The present invention relates to a cash register. comprising several totalizers, in particular general totalizers and individual totalizers, each composed of several rotating discs, as well as the usual auxiliary mechanisms, such as an indicating device and a printing mechanism.



   The object of the invention is, on the one hand, to simplify the construction of such a body by the arrangement of the totalizers and other members on longitudinal shafts so that their number can be increased by the addition of members. similar on their respective trees; on the other hand, to make its operation very expeditious, independently of the number of totalizers, by the simultaneous control of all the totalizer disks intended to intervene in an operation in progress, as well as of the auxiliary mechanisms participating in it.

   At the same time, the invention aims to improve the operation of the cash register by using the same operating members, both for the recording operations and for the operations of resetting the totalizers, these same units. furthermore suitable for actuation of the indicator

 tcur and the printing mechanism.



   According to the invention, the motor unit of the register simultaneously actuates a control shaft of all the totalizers and of the operating mechanisms which coordinate the movements of the totalizer discs and of the components of the auxiliary mechanisms.



   The control tree of the totalisers performs during each operation a movement of invariable amplitude, while the operating mechanisms, each of which corresponds to a different numerical order, intervene under the control of the keyboard or other control device. setting numbers, to stop the totalizing discs of each numerical order in the respective positions corresponding to the recording to be made. The movement of the control shaft is advantageously a rotation of one full turn, followed by a rotation of one turn in the opposite direction.

   In order to act on the totalizer discs, which are threaded in a known manner onto the control shaft, the operating mechanisms can be arranged so as to cooperate with this shaft either during its forward movement or during its backward movement. return.



   With a view to selecting and actuating the totalizers, there are interposed between the control shaft and the totalizer discs coupling devices which, during recording operations, are controlled by the operating mechanisms. - counters, while during the zeroing operations they are controlled by the totalizer discs themselves. These coupling devices include coaches in a number equal to that of the disks and capable of being brought into engagement with the latter, and all the coaches of the same numerical order are mounted on a common support carried by the drive shaft. control. By acting on this support using the operating mechanism of a given order, it is thus possible to simultaneously actuate all the disks of the same order participating in the same operation.



   To each operating mechanism are, on the other hand, adjoining bodies which intervene to determine the operation of the auxiliary mechanisms, in particular the indicator and the impediment.

  External view.- The cash register shown in the drawing (Fig. 1) has the shape of an elongated cash register resting on a plate 101 on which stand up, inside, transverse partitions 102, 103 and 104 which serve as supports for the internal parts of the body, protected by a cover plate 105.



   On its front face, near the right end, the cash register has a keypad 215 for setting the amount to be recorded. The keypad is flanked, on its left, by a selection lever 290, surmounted by 'a handle 290' and used to select which of the individual totalizers to participate in the current operation. The individual totalizers are, in the example shown, four in number, designated by A, B, D and E (Fig. 3). In addition, the cash register includes a ticket totalizer K, a day totalizer J and a general totalizer G; the amounts totaled by each of the totalizers are directly readable in windows 106 aligned to the left of the key holder and normally covered with a locking shutter, omitted in FIG. 1.



   To the right of the keypad is a control lever 310 surmounted by a handle 310 'and intended to be placed in

  <Desc / Clms Page number 8>

 one of its positions which correspond to the nature of the operation to be performed: simple recording, zeroing of a totalizer, etc.

   At the right end of the front wall is a large button 440 called the trigger button, which is pressed to start the electric motor housed inside the body, in order to make the prepared operation effective. using the keys and levers 290 and 310. Below the trigger key 440 is a repeat key 460 which allows several recording operations relating to the same amount to be repeated without having to to set, each time, this amount using keys 215.

   A button 475 in the right side wall is used to deactivate the repeat key when the series of operations involving an unchanging amount is completed. A crank 516 operates the cash register at the. hand, if the electric current fails.



   The amount of each transaction is made visible, in large characters, by a plate indicator 601 surmounting the cash register.



  The same amount is printed on a receipt issued at 856 through the left wall of the cash register. The date on each ticket is made up by a composter 716 accessible from the outside, also on the left wall. Inside the cash register, the amount of each transaction is also printed on a control strip, and the amounts of the last few transactions are visible in a window 107 in front of which the control strip passes. The key 790 in the left wall is used to replace the reel from which this tape unwinds.



   In the middle of the machine, to the left of the selection lever 290, windows 108 show the counter indications which count the number of operations of the day totalizer and of the individual totalizers, as well as the number of operations without recording, say "change".



   Finally, a lock 486 located to the right of the control lever 310 makes it possible to prevent any unauthorized use of the device.

  <Desc / Clms Page number 9>

 checkout, blocking all of its control devices.



   We will now describe the assembly of the various components of the cash register.



   Totalisers.- These are all mounted in the upper part of the machine, between the transverse partitions 103 and 104 (Fig. 3); they are all of identical construction except for the number of disks, so that only one will be described, for example the individual totalizer D.



   Each totalizer is composed of a certain number of annular discs 110 comprised between two flanges 111, 111 'and each corresponding to a numerical order, each disc has ten teeth on the outer periphery. In the totalizer D there are six disks 110, which makes it possible to totalize amounts up to a total of 9999.99. The discs are juxtaposed and threaded on a control shaft 100 common to all the totalizers. The discs 100 surround the shaft 100 with play and they are each supported on the outside by three rollers Il, 113 'and 114 which engage in a peripheral groove of the disc 110, and are themselves respectively mounted. on shafts 115, 115 'and 116, parallel to the shaft 100 and carried by the flanges 111 and 111' of the totalizer.



  These flanges are threaded, at their lower part, on a guide 117 fixed between the partitions 103 and 104, parallel to the shaft 100.



  At their top, the flanges 111 and 111 'end in forks which receive in their hollow a fixed shaft 118 supported by means of sleeves 119. These serve to hold the packages in place on the shaft 118. toothed wheels 120 similar in diameter and number of teeth to discs 110. Each toothed wheel 120 meshes with a totalizer disc 110, the number of wheels 120 in each pack being equal to the number of discs 110 in the total. - corresponding sateur. The peripheral surfaces of each of the ten teeth of each wheel 120 bear the numbers from 1 to 0, visible through the window 106 of the casing 105 of the machine and used for reading the amount totaled by the totalizer in question.

  <Desc / Clms Page number 10>

 



   The totalizer disks 110 are operated as follows:
At its inner periphery, (Fig. 4) each disc has a mentonnetllO 'in which are cut a number of notches 121, for example ten in the case shown, with which the coaches 122 carried by the liner can cooperate. shaft 100. There is a driver 122 for each of the totalizer discs intended to be actuated directly; only the disks of the upper numerical orders of the general totalizers G and J are actuated only by transfer and do not have a driver in front of them. All the trainers 122 corresponding to the disks 110 of the same numerical order in the various totalizers are wedged on a bar 123 housed in a longitudinal groove 124 of the shaft 100 (FIG. 4).

   There are therefore, in the shaft 100 at least as many grooves 124 with bars 123 carrying coaches 122 as there are disks 110 actuated directly in any one of the totalisers. The bars 123 are distributed around the shaft 100 with the same angular spacing as the notches 121 inside the discs 110. Each bar 123 constitutes, with all the coaches that it carries, a coupling device for the control. totalizer disks: for recording an amount on one or more totalizers, it is necessary to bring the coaches 122 into engagement with the notches 121 of the disks 110 which are to participate in the operation, and to make turn each disc in the desired direction as many tenths of a turn as there are units.



   As shown in Fig. 3a, the width of each driver 122 is less than the thickness of a totalizer disc 110. On the other hand, the chin 110 'in which the notches 121 are formed, also occupies only part of the length. The thickness of each disc, while beside this part the internal diameter of the disc is large enough to form an annular hollow in which the driver can rotate freely. When the

  <Desc / Clms Page number 11>

 machine is at rest, none of the coaches 122 is engaged with the corresponding disc 110, all of the coaches 122 being in the annular recesses of the discs.

   Each totalizer intended to participate in a recording operation must therefore be moved, with its flanges 111 and 111 ', along the guide 117, from left to right in FIG. 3, from a distance such that the notches
121 engage with coaches 122.



   Selection of individual totalizers.- The selection of an individual totalizer is prepared, at. start of the recording operation, using lever 290 (Fig. 23), the handle 290 'of which is on the outside of the machine, to the left of the keypad (Figs. 1 and 2 ). This lever which turns around a central shaft 300 of the machine (Figs. 23, 24) can occupy several positions, depending on the totalizer to be selected, and these positions are indicated by an arrow integral with the handle 290 'at look at the corresponding indications written on the envelope 105 of the machine.



   The lever 290 drives in its angular displacements, a toothed sector 282 which meshes with a pinion 149 wedged at the right end of a selection shaft 125 (Figs. 6,8 and 23). This shaft rotates freely in the partitions 103 and 104 and carries, for each of the totalizers, a fork 181 intended to grip between its claws a tooth 127 of the flange 111 'of each totalizer (Figs. 4 and 10).



   The claws of the various forks 181 are angularly offset, from one fork to another, by an angle corresponding to that described by the lever 290 when passing from one position to the next. It is therefore understood that, depending on the position of the lever 290, one or the other fork 181 is made to grip the tooth 127 of the flange of the corresponding totalizer and that it is then sufficient to move the shaft.
125 from left to right by an appropriate distance, so that the disks 110 of the selected totalizer are brought into engagement with the drivers 122 which will allow the latter to actuate the totalizer disks.



   The axial movement of the shaft 125 is derived from the motor shaft 500 (Figs. 36 and 37) which is rotated, in the manner

  <Desc / Clms Page number 12>

 described later, at the start of each machine operation. The shaft 500 carries a toothed wheel 511 which meshes with a toothed wheel 512 mounted on a shaft 150. This also carries a groove cam 151 (Figs. 37 and 8). A roller 152 located at the end of an arm 153, is engaged in the groove of the cam which has a profile such that during a revolution of the cam, the arm 153 receives from the edge a movement in the direction of needles. a watch then, after a stop, returns to its original position. The arm 153 is fixed on an axis 154 which oscillates in a support 155 mounted on the guide 117 (fig.3 and 8).

   At its other end, the pin 154 carries a U-bent lever 156 (Figs. 6,8 and 9), elastically connected by a compression spring 157 to an elbow lever 158. The latter is crossed by a spindle 159 which also passes through two uprights 160, 160 'pivoting on the axis 154. The spindle 159 can, moreover, engage in the notches 161 of two plates 162 vertically guided, respectively by buttonholes 163 and 164, on the axis 154 and on two pivot screws 165 engaged in a ring 166 surrounding the shaft 125. The ring 166 can rotate on the shaft 125, but its axial movement is prevented by two fixed bars 167 which flank it on both sides.

   When the selection of one of the totalizers being prepared by the operation of the selection lever, the shaft 150 describes one revolution, the arm 153 oscillates the axis 154 with the levers 156 and 158, and the spindle 159. That here, engaged in the notches 161, driven, to the right in FIG. 6, the plates 162 and, by the screws 165, the ring 166. The shaft 125 must follow this movement and that of its forks 181 which has been brought into engagement with the. tooth 127 of a totalizer, drives it to the right in FIG. 3, the quantity desired to bring the notches 121 of its discs 110 into engagement with the coaches 122.



  The travel of the selected totalizer is limited by the meeting of its flange 111 with an adjustable stop 128 (Fig. 3) screwed into a support 129 fixed on the guide 117. At the end of the operation, the totalizer is returned to its position. resting by the cam 151

  <Desc / Clms Page number 13>

 and the arm 153 aided by a return spring 130 stretched between the support 129 and the flange 111 '; this same spring also prevents any untimely displacement of an unselected totalizer.



   Some machine operations, such as resetting the D-day totalizer to zero, do not require the axial movement of the individual totalizers. In view of these operations, therefore, the mechanism which has just been described must be rendered inoperative. For this purpose, the control lever 310 (Fig. 27) is used, the button 310 'of which is located outside the machine.



  Before carrying out an operation, the lever 310 is brought into the corresponding position, the designation of which is indicated next to the button 310 '(FIG. 2). In its movements, the lever 310 drives by a connecting rod 307 articulated to the lever at 403 and by an intermediate lever 308, a pin 306 (Figs. 27 and 10) on which is wedged a lever 171 articulated to a fork 172 guided on a shaft 168 parallel to the shaft 125. One of the branches of the fork 172 carries a rack 169 which meshes with a pinion 170 wedged on the shaft 168. A cam 173 (Figs. 7 and 8) is integral with this pinion. the groove of which slides a tenon 174 carried by a connecting rod 175 that a buttonhole 176 guides vertically on the shaft 168.

   At its lower end, the connecting rod 175 is extended by a horizontal part which carries two arms 177 (Figs. 6 and 8) pierced with buttonholes traversed by a pin 178 which also passes through the plates 162. When the control lever 310 is brought into a position which corresponds to an operation requiring the selection of one of the individual totalisers, all the members described occupy the positions shown in Figs. 6 and 8 and the selection is made as described.

   But when the lever 310 is brought into one of the "zeroing the day totalizer" or ticket total positions which does not require the selection of individual totalizers, this lever, by the connections described: connecting rod 307, lever 308, axis 306 , lever 171, fork 172, gears 169-170 and shaft 168 - rotates cam 173 which, through lug 174, connecting rod 175, arms 177

  <Desc / Clms Page number 14>

 and pin 178 lowers plates 162 such that their notches 161 clear pin 159, and other notches 179 of these plates catch on a fixed pin 180 mounted on support 155.

   In this position, the rotation of the cam 151, which causes a pivoting of the spindle 159, has no effect on the selection shaft 125, and none of the individual totalizers is moved laterally.



  Selection of the general totalizers.- The connections which, for certain positions of the control lever 310 render inoperative the mechanism for selecting the individual totalizers, are also used to carry out, as required, the selection of the totalizers G, J and K. The Flanges 111 'thereof, like the flanges of the individual totalizers, each have a tooth 127 capable of being gripped by forks similar to the forks 181 acting on the individual totalizers. However, the forks for the grand totalizers are 'wider in the angular direction and are subdivided into two parts 182, 182' (Fig. 12) to be able to intervene in several angular positions.

   These forks are carried by a sleeve 183 (Figs. 6,7, 11,12) which surrounds the shaft 125 and carries a toothed wheel 184 in mesh with a toothed wheel 185 wedged on the shaft 168. A fork 186 , engaged in a groove of the hub of the. toothed wheel 184 connects the sleeve 183, by a connecting rod 187 integral with the fork 186, to the upright 160 which, as already described, pivots from left to right at the start of rotation of the machine then, after a stop, returns to its resting position. The sleeve 183 therefore receives an axial movement which, through the forks 182, 182 'is transmitted to the selected grand totalizers, just as has been described for the individual totalizers.

   The transmission of the angular movement of the lever 310 to the sleeve 183 is such that the five positions of the lever correspond as many angular positions of the sleeve with the forks 182, 182 '; the width and the angular arrangement of these on the sleeve 183 are determined with a view to actuating the totalizer (s) which must per-

  <Desc / Clms Page number 15>

 ticipate in the planned operation:

   When (Fig. 2) lever 310 is in the first down position, (zeroing an individual totalizer), none of the general totalizers are selected, none of the forks 182, 182 'being in operation. taken with the teeth 127 of their flanges 111 '; in 2nd. position (single recording), the day totalizer D and the general totalizer G are selected to participate in the operation, in addition to the individual totalizer selected, as described, using the lever 290; in 3rd. position (recording at several stations), the three totalizers G, J and K are selected; in 4th. position (ticket total), the ticket totalizer K alone is active; finally, in 5th. position, only the D-day totalizer is selected, to be reset to zero.



  Control of the totalizers.- When any totalizer is selected, that is to say when the notches 121 of its discs 110 are brought into engagement with the coaches 122, these are used to rotate each of the discs. 'as many tenths of a turn as this disk has to register units. The rotation of the discs is done, for an addition, in the direction indicated by the arrow in Fig. 20, and in the reverse direction for a subtraction, that is to say for the resetting of the totalizer.

   As already said, there is, in each totalizer, a driver 122 for each disc 110; the coaches which belong, in the various totalisers in the same numerical order, are grouped on the same .bar 123, and all the bars 123 participate in the rotation of the shaft 100 which performs one complete revolution for each operation of the machine. The bars 123, with the drivers which they carry, constitute couplings between the shaft 100 and the discs 110. The movement of the shaft 100 is derived, like all the others, from the motor shaft 500 which, he, too, makes a complete revolution per operation.

   The shaft 500 carries a toothed wheel 511 (Fig. 37) which, by an intermediate gear 537 wedged on the shaft end 539 transmits the movement to a toothed wheel 538 wedged on a shaft 200, located at the bottom and at the bottom. rear of the machine, between - partitions 103 and 102 (Figs. 13 and 14). A pair of 187,188 cams

  <Desc / Clms Page number 16>

 fixed near the right end of the shaft 200 positively control a double lever 189 which carries two rollers 190 and 191 co-operating with the cams 187 and 188, respectively. The lever 189 can pivot on an axis 192 and is articulated at the top, in 193, to a connecting rod 194 in the form of a fork. The pivot 193 is guided in the rectilinear window 195 of a fixed support 196.

   The two arms of the fork 194 form outwardly facing slats each furnished laterally with a small cup 197, 197 'respectively. By its two jaws, the fork 194 can be hooked to one or the other of two lugs 198 and 199 fixed on the side of a toothed sector 201 which can rotate on the central shaft 300.



   The toothed sector 201 meshes with a pinion 202 wedged on the control shaft 100, near its right end (Fig. 3).



  At rest, the pinion 202 is located substantially in the middle of the toothed sector 201 which can therefore rotate the pinion in either direction. The profiles of the cams 187 and 188 are such that, during the rotation of the shaft 200, the lever 194 hooked to the lug 198 causes the shaft 100 to rotate first one turn clockwise. 'a watch then, after a moment of rest, a turn in the opposite direction. If, on the other hand, the lever 194 attacks the toothed sector 201 via the lower lug 199, the shaft 100 performs the same movements in reverse order.



   To prevent the fork 194 from unhooking during travel, a segment 203 is pivotally mounted on the shaft 300. The radius of the circular part of the segment 203 is such that this part comes to support one or the other. another bucket 197 or 197 'of the fork 194 when the latter is hooked to one or other of the lugs 198, 199. In addition, the fork 194 is supported by one or the other of two tenons 204 , 204 ', fixed on segment 203; depending on whether the fork is hooked to the lug 198 or to the lug 199, the lugs 204 'or 204 come to rest respectively from below or from above, on a small plate 205 fixed to the fork 194.



  To reverse the initial direction of rotation of shaft 100, it suffices

  <Desc / Clms Page number 17>

 therefore made to pivot the segment 203 downwards (Fi.g. 13) until the tenon 204 butts against the plate 205 and pushes it downwards, with the fork 194 which then unhooks from the 'lug 198 and hooks up to lug 199. In this movement, the fork is guided by the elongated lips 206 and 206' of the tips of the fork, which also serve to limit the travel of the toothed sector 201 .



   The segment 203 is controlled, with a view to changing the initial direction of rotation of the shaft 100, by the control lever 310, already mentioned. This lever (Fig. 27) has a profiled slot 357 in which can slide a roller 358 carried by one of the arms of an elbow lever 359 (Figs. 13 and 27), pivoting on a fixed axle end 458. The another arm of the lever 359 ends in a fork to grip a button 207 fixed on the segment 203.

   The profile of the groove 357 is such that when the lever 310 is in the second or third position from below, in FIG. 2, ("single ticket'11 or" ticket with addition "positions) the roller 358 is engaged in the lower part of the groove 357 (Fig. 27) and the fork 194 is hooked to the lug 198 of the toothed sector 201 ( Fig. 13), so that the rotation of the shaft 100 starts in a clockwise direction, which corresponds to an addition operation.

   If the lever 310 is moved to one of its other three positions, the roller 358 sliding in the groove 357 rotates the lever 359, the segment 203 and the yoke 194 so as to bring the yoke into engagement with the yoke. lug 199 of the toothed sector 201 and to reverse the initial direction of rotation of the shaft 100, as required by the operations prepared by the movement of the control lever.



   When a cash register operation, for example a simple addition on an individual totalizer, has been prepared by the described maneuvers of levers 290 and 310, it is a matter of rotating each disc of the selected totalizer by the same amount. tenths of a revolution that the disc must register in units. As already said, the shaft 100 which carries the tie rods 123 on

  <Desc / Clms Page number 18>

 which are threaded the coaches 122 performs, during the operation, a complete turn in the desired direction and then, after a short stop, returns to its starting position. The drivers are normally in the active position with their points directed radially with respect to the shaft 100 and engaged in the notches 121 of the disks of the selected totalizer (s).



   A star-shaped braking device 131 (Fig. 5) intended to prevent inadvertent pivoting of the coaches 122, is wedged on the shaft 100, near the right end thereof (Fig. 3). The hub of the star receives the ends of all the bars 123 which carry the coaches 122. Next to the star 131 is wedged, on each bar, a small lever 1324, the free end of which carries a roller 133 taken between the two jaws of a clamp 134, 134 ', Each of these clamps has its pivot! 35 fixed near the periphery of the star 131 and its two arms are connected to each other by a spring 136. There is therefore a clamp 134, 134 'by driver 122 of each totalizer, and for convenience, two neighboring clamps are mounted alternately to the right and left of star 131.



  For greater clarity, Figs. 3 and 5 show only two clamps.



   When, at the start of the operation of the body, the shaft 100 is set in rotation, the star 131 and all the parts which it carries participate in this movement. To the same movement also participate toothed wheels 137 wedged on the shaft 100 (Fig. 3) between the totalisers and star 131 as well as coaches 138 similar to coaches 122, but a little wider, wedged on the bars. 123;, there is a driver 138 in front of each toothed wheel 137 and its tip is engaged in an interior groove 139 of the wheel 137. The number of the toothed wheels 137 is equal to that of the numerical orders in the highest digit. high on which a cash transaction can relate, ie seven in the example shown.



  Each toothed wheel 137 engages with a toothed sector 240) Fig.



  17) which rotates on the central shaft 300, and the amplitude of which is regulated by pressing one of the keys of the order

  <Desc / Clms Page number 19>

   corresponding nmeric. Thus, when an amount comprising, for example, 1 tens and 5 units, the "1" key for tens stops, as described later, the corresponding segment 240 after a determined rotation, while the segment analog 240 cooperating with the keys of the units is stopped, after a rotation five times greater, by the key "5" of the units. With the tens segment 240, the corresponding toothed wheel 137 is also stopped, after a rotation of one tenth of a turn.

   From this moment, its driver 138 wedged on a bar 123 cannot therefore continue its rotation with the bar 123 and the shaft 100, while remaining in the active position, with its tip directed radially with respect to the shaft 100. As the shaft 100 advances in its rotation, the driver 138 therefore pivots with the bar 123 to disengage from the groove 137, until it reaches a lying position similar to that in which FIG. . 21 shows a trainer 122.



  During this pivoting of the bar 123, all the drivers 122 wedged on the same bar, that is to say belonging to the numerical order of tens in the various totalizers, are also tilted, so that those , which were engaged in notches 121 of the disks 110 are released after having driven the disks 110 of the tens of all the selected totalizers by a tenth of a revolution, in accordance with the number "1" to be recorded. This uncoupling process is repeated for the disks of each numerical order, at the moment when these disks have made as many tenths of a revolution as they have to register units.



   While a bar 123 pivots, allowing the trainers 122 and 138 that it carries, to disengage from the notches 121 and 139 in which they were engaged, the lever 132 that this bar carries pivots in the same way as the coaches, and its roller 13 moves one of the jaws 134, 134 'against the action of the spring 136, while the other is held in place by a stop 141 which rests against the neighboring branch of the star 131. The springs 136 thus serve to oppose any untimely pivoting of. bars

  <Desc / Clms Page number 20>

 123 with the coaches 122 and 138, because, as long as these are not tilted by the depression of a key, they cannot produce the extension of the spring 136.



   The profile of the notches 121 (Figs. 4 and 20) is such that during the pivoting of the coaches 122 their point forces the discs 110 which they have just driven to remain stationary, which prevents the rotation of these discs, by inertia, in the process. -beyond the desired position. In addition, the correct alignment of the totalizing discs 110 is ensured by pawls 142 which are mounted on the shaft 116, one per disc 110 and are elastically inserted under the action of springs 143 between the teeth of the discs.



    Mechanism for installing the upright (keypad of keys ¯,), .- Keys 215 (Fig. 2) whose depression determines the amplitude of rotation of the totalizing discs 110 are grouped, on the front face of the machine, in a keyboard comprising as many columns as there are digits in the largest amount that can be recorded at once, ie five in the example shown. Each column has nine keys bearing the numbers 1 to 9, mounted in a curved support 210 (Fig. 17, 18) which is carried by two longitudinal bars 211 and 212.

   The latter has, over the entire width of all the supports 210 a flat 213 which allows, after an appropriate rotation of the bar 212, to individually lift for assembly or disassembly, each of the supports 210 which then pivot. around the lower bar 211. The rod 216 of each key is guided in a recess of its support 210 and supported laterally by the cover 214 thereof (Fig. 18). A tab 217 integral with each rod 216 engages in the recess of the support and presses on a return spring 218 mounted in this recess, around a pin 219 which also serves as an additional guide for the rod 216. by crossing a notch in the tongue 217.

   The stroke of the key is limited, downwards, by a heel 220 near the top of the rod 216, and upwards by a nose 221 of the rod. The lower surface of the nose 221 is tilted and

  <Desc / Clms Page number 21>

 cooperates with a lug 222. All the lugs 222 of the same column of keys are fixed on an oscillating arc called the trigger arc 223 suspended from the support 210 at the top by a link 224 and at the bottom by a trigger 225, these two parts being able to pivot on pins 226 and 226 'respectively. The trigger arc can therefore oscillate a small amount, substantially along an arc of a circle having the shaft 300 as its center.

   When a key is pressed, its nose 221, acting on the corresponding lug 222, slightly pushes the trigger 223 clockwise, against the action of a spring of return 227, until the lug 222 enters a notch 228 of the nose 221 by a small backward movement of the arc 223, under the action of the spring 227. The pressed key can therefore no longer go up. under the action of its spring 218.



   The trigger arc 223 is flanked by a locking arc 229, guided by rods 230 and 231 oscillating respectively on the pivots 226 and 226 '. The locking arc 229 has angled notches 232 in a number equal to that of the keys of a column, ie new, which can cooperate with lugs 233 each fixed to the side of a rod 216. Normally, the lugs 233 are located above the arch 229, opposite the entrance of the elbow cutouts 232 which each have a radial part, and a side part. When a key is pressed, its lug engages in the angled notch to the bottom of its radial part.



  During the operation, the arc 229 is moved, by means described below, in the direction of clockwise, so that the lug 233 of each pressed key is engaged in the lateral part of the key. the notch 232 and remains retained there by the outer edge thereof; this edge is also present in front of the lug of each key not pressed, so that until the end of the operation, that is to say until the arc 229 is brought back to its normal position no new key can be pressed, whereas keys already pressed cannot be released unexpectedly.

   However, before moving the locking arc, we

  <Desc / Clms Page number 22>

 can correct an error made in the choice of the keys pressed: when, in addition to a key pressed by mistake, another key of the same column is pressed, this one advances the trigger arc 223, as described , and at this moment the first released key rebounds under the effect of its return spring 218.



   The keyboard does not include "zero" keys, the function of which is fulfilled, in each column, by a pawl 234 (Fig. 17) mounted on a pivot 235 fixed on the support 210. The pawl 234 is biased by a spring. 236 which keeps it tilted towards the center of the machine. In this position, the pawl 234 rests on a pin 237 carried by the trigger 225. When, on depressing a key, the movement of the trigger arc 223 causes the trigger 225 to oscillate in clockwise, pin 237 lifts pawl 234 which becomes inoperative. when, on the other hand, the figure to be recorded in the considered column is "0", there is no key to press, and the role of pressed zero key is played by the end of the pawl 234.



   When an amount to be recorded is set using the keys, the control shaft 100 is rotated as already described in an anti-clockwise direction (Figs. 17 and 20), to record the amount on the selected totalizer (s); the rotation can also start in the opposite direction, in the case of a zeroing operation. At the same time as the control shaft 100, the central shaft 300 receives movement in the same direction and of the same amplitude, derived from the same camshaft 200 (Figs.



  15 and 16). The double lever 189 which controls the forked connecting rod 194 also controls, by means of a connecting rod 208 and a journal 209, a toothed sector 146 freely rotating the central shaft 300. The toothing of the sector 146 is identical to that of the sector 201 which actuate the shaft 100, and the amplitude of rotation of the two sectors is the same; however, the rotation of the sector 146 always starts in the same direction. The toothed sector 146 meshes with a pinion 144 attached to a pinion 145 of a slightly larger diameter. The two gears

  <Desc / Clms Page number 23>

 are idle on the shaft 100, and the pinion 145 meshes with a toothed sector 147 wedged on the central shaft 300.

   This return is determined so as to achieve a maximum amplitude of the sector 147 equal to the angle formed by the spokes going from the shaft 300 respectively to the "9" key and to the zero pawl 234, (Fig. 17). .



   Operators.- The toothed wheels 137 which the shaft 100 carries, each have a tooth 148 a little wider than the others (Figs. 3, 17 and 19), which can come into engagement with an isolated tooth
241 carried by sector 240 slightly out of the plane of its other teeth. The tooth 148 only hits the isolated tooth 241 when the rotation of the shaft 100 begins in the counterclockwise direction, which corresponds to a recording operation; it then drives the sector 240, the teeth of which engage with the ordinary teeth of the toothed wheel 137.



   On the other hand, each toothed wheel 137 is engaged with one of the teeth of a double pinion 242 idle on an axis 243 supported by the partition 103 and by a fixed support 238 (FIG. 19). The other toothing of pinion 242 can mesh with a toothed sector 245, rotating on shaft 300. This second toothing of pinion 242 has a larger tooth 244, and the toothed sector 245 an isolated and laterally offset tooth 246. These two special teeth do not engage, at the start of the rotation of the shaft 100, until this rotation begins in the direction of clockwise, which corresponds to a zeroing operation. Thus, depending on the initial direction of rotation of the shaft 100, it is the sector 240 or the sector
245 which is driven in a clockwise direction.



   One or the other of the toothed sectors 240 and 245 drives in its rotation, a plate 248 which can pivot on the shaft 300.



   To this end, the sector 240 has a tab 239 (Fig. 18) perpendicular to the plane of the sector, while the sector 245 carries a tab 247. The plate 248 has a nose 249 offset laterally so as to be located in the plane of the shanks 216 of the keys (Fig. 18) and which is long enough to strike the shank of a pressed key or the end of the zero pawl 234 when the latter is not

  <Desc / Clms Page number 24>

 statement. The plate 248 also carries a lock 250 guided radially by two rods 251 and 252 articulated on the one hand to the nose 249 and the other to the lock 250. On the rod 252 is fixed a roller 253 which engages, normally, in a notch 254 of a sickle-shaped segment 255, the hub of which is wedged on the shaft 300.

   Since the rotation of shaft 300 is synchronous with that of sector 240, members 240, 248, 250 and 255 move, during the recording operation, together until nose 249 of the plate 248 is stopped by the pawl 234 or by the rod of a depressed key. The shaft 300 continues its rotation with the segment 255 which forces the roller 253 to disengage from the notch 254 of the segment and to advance the latch 250 in a radial direction, against the action of a return spring 256, until 'so that the point of the lock engages in one of the notches 257 that the support 210 of the keys has at its inner periphery.

   The roller 253 rolls on the segment 255 which continues to advance, while the plate 248 remains stopped, with the segment 240 and the toothed wheel 137 in an angular position determined by the numerical value of the pressed key. As already described, this stop has the consequence that the trainer 138 (FIG. 3) disengages from the groove 139 of the toothed wheel 137 causes the bar 123 to pivot with the trainers 122 which it carries and immobilizes the bars. discs 110 which have just marked the number corresponding to the pressed key. If the digit to be marked is "0", the nose 249 is stopped by the pawl 234 from the start, as if a "0" key located before the "1" key had been pressed.

   However, the shaft 100 and, with it the coaches 122 and 138 which are placed in the inactive or inclined position, as shown in FIG. 21, continue their rotation to complete the complete turn. Shaft 300 also continues to rotate and stops when the tip of segment 255 is near roller 253.



   During the return rotation of shaft 100, the drivers 138 which had participated in the operation remain in an inclined position, with their tips pointing in the direction of movement. When

  <Desc / Clms Page number 25>

 a driver 138 meets the groove 139 it engages there (Fig. 17) by straightening up under the action of the spring 136 (Fig. 5), and returns the toothed wheel 137 to the rest position. This gear also drives the corresponding sector 240 towards the rest position, as long as their teeth remain in engagement.

   It should be noted that for their part the coaches 122 do not bring back the totalizer discs 110 which they have just actuated, because before the backward rotation of the shaft 100, the lever 153 controls by the the cam 151 (Fig. 8) has returned the selected totalizers, by an axial movement from right to left in FIG. 3 in the rest position, so that the drivers 122 can freely rotate and straighten in the annular space of the discs 110.



   At the same time as the shaft 100, the shaft 300 returns back with the segment 255. As soon as the notch of the latter comes below the roller 253, the latter engages therein and allows the spring 256 to remove the lock 250. The plate 248, thus released, is also brought back and, by acting on the tab 239 of the toothed sector 240, it completes the return thereof to the rest position.



   The operation is analogous during the resetting of a totalizer. In this case, the control lever 310 having been placed in the corresponding position, and the totalizer to be reset being ¯ selected using the lever 290, (in the case of one of the individual totalizers) , the rotation of the shaft 100 begins, as already described, in a clockwise direction (Fig. 17). The plates 248 of all the numerical orders involved in the operation are therefore driven through the gears 137 and 242 and toothed sectors 245, while the sectors 240 remain stationary.

   The discs 110 of the totalizer are all driven in the opposite direction to that in which they rotate during recording, by the coaches 122, each of which is in engagement with one of the notches 121 of the corresponding disc.

  <Desc / Clms Page number 26>

 corresponding. Each disc 110 which meshes with a reading wheel 120, drives the latter in its rotation and is stopped, when it reaches the zero position, by a stop tooth 140 integral with the wheel 120 (FIG. 20). As shown in Fig. 3, each wheel 120 is integral with a ring 126 capable of rotating on the fixed shaft 118. It is on the ring 126 that the tooth 140 is formed which mainly serves, in cooperation with a transfer cam 262 carried by a shaft 264, to prepare the transfer of the tens of a disk 110 to the neighboring disk 110 of higher numerical order.

   But during the zeroing of the totalizer, when the wheels 120 turn counterclockwise, the tooth 140 of each wheel hits the part 281 of the cam 262 as the wheel 120, and with it, the corresponding disk 110, reaches the zero position. At this moment, the disc 110 stops, but its driver 122, tilting with its bar 123 to disengage from the notch 121, continues its rotation with the shaft 100 until the completion of a revolution full. Of course, the discs of the same totalizer which, before setting to zero, marked different figures, stop at different times, each after as many tenths of a turn as it marked units.



   At the same time as each disc 110, also stops the toothed wheel 137 which corresponds to the same numerical order, and this because the pivoting of the bar 123 releases the driver 138 from the groove 139 of the toothed wheel 137. With this last, the pinion 242 and the toothed sector 245 also stop. The plate 248, would precede driven by the sector 245, by the intermediary of its tab 247 acting on a part 258 integral with the plate, is also stopped because a hook 259, oscillating on a pivot 260 carried by the sector 245, hooks, under the action of a spiral spring 261, to part 258 and makes plate 248 and sector 245 integral.

   On the other hand, the segment 255 continues its rotation with the shaft 300 and pushes back, as previously described, the roller 253 with the latch 250 which locks the plate 248 in the position.

  <Desc / Clms Page number 27>

 tion corresponding to the number which was marked by the disc 110 of the same numerical order. Plate 248 is held in this position until the return rotation of shaft 100 returns all of the mentioned members to their rest position, just as after a recording operation.



   The hook 259 which has just been mentioned fulfills yet another function which consists in preventing the inadvertent entrainment of one of the toothed sectors, 240 or 245, when the other is activated. To this end, on returning to the rest position after a zeroing operation, the hook 259 hits a yoke 370 which extends over the entire width occupied by the key mechanism, and is released, by a pivoting movement in counterclockwise, of part 258, which will allow plate 248 to accompany sector 245 to the next recording operation. At the same time, the hook 259 is hooked, by a notch at its lower end, to the sharp edge of the yoke 370, so that the toothed sector 245 to which this hook is integral, cannot move during the operation of 'recording.

   On the other hand, when the operation to be carried out is a setting to zero, the yoke 370 is tilted, for a purpose and by means described below, in an anti-clockwise direction, which frees the yoke. hook 259 and allows it to hook again to room 258, so that sector 245 can participate in the operation.



   The shaft 300 carries, for each numerical order, in addition to the components already described, a bifurcated lever 631 and a sector 632 which communicate the movements of the shaft respectively to an indicator mechanism and to a printing mechanism, in order to make visible and print on receipts or cards the result of each recording or zeroing operation of the cash register. These mechanisms will be described later.



  Transfer Mechanism.- We have described how to make each totalizer disc 110 turn by as many tenths of a turn as this disc

  <Desc / Clms Page number 28>

 must mark units, this angle of rotation being limited by the depressing of one of the keys 215. It goes without saying that, when a disc passes, during a recording operation, from the position "9" to the "0" position or beyond, one unit must be carried over to the adjacent left-hand disc 110 (Fig. 3) ie to the disc 110 of the next higher numerical order. This transfer of the tens is effected with the aid of the rings 126 (Figs. 20, 21), each of which flanks a reading wheel 120 in engagement with a totalizer disc 110.

   Each ring 126 has a tooth 140 which cooperates with the corresponding transfer cam 262 of which is integral a transfer part 263, located, like the cam 262, on a shaft 264, but opposite the adjacent disk 110 on the left. The shaft 264 is mounted, parallel to the shaft 118, between two supports 265 which can pivot on a shaft 266. The distance between the shafts 264 and 118, during the operation of the machine, and the angular position rings 126 on the latter are such that when a disc 110 changes from "9" to "0", its transfer tooth 140 enters a notch 267 of the corresponding cam 262 and causes it to rotate, with its transfer part 263 , counterclockwise, at an angle such that the finger 268 of the part 263 comes to be placed in the path of the blades 269 fixed on the shaft 266.

   This rotation of the parts 262-263 takes place against the tension of a spring 270 stretched between each part 263 and a spring-holder bar 271 connecting the supports 265 between them. Each spring 270 therefore tends to return its part 263 to the rest position where it leans against a fixed bar 272 bracing the supports 265.



   The part 262-263, moved by the transfer tooth 140, nevertheless remains in its new position of preparation for the transfer, because of the pressure of the pawl 142 on the disc 110, which does not allow the spring 270 to bring back in. rear part 262-263 with ring 126 and discs 120 and 110.

   Subsequent clockwise rotation of shaft 266 brings one of the blades 269 into engagement with finger 268 of part 263 and rotates

  <Desc / Clms Page number 29>

 this at a certain angle such that a tooth 279 of this part, coming into engagement with one of the teeth of the toothing of the corresponding wheel 120, rotates the latter as well as the corresponding disc 110 by a tenth of a turn, after which, the transfer being thus accomplished, the wheel 120 is blocked by the meeting of its next tooth with the part 280 of the part 263.

   If the wheel 120 was originally in position 9, its rotation caused by the transfer would in turn prepare the transfer by one unit to the next left wheel, and this transfer would be made effective by the blade 269 which follows the one that completed the first postponement. The shaft 266 makes two complete revolutions with each machine operation, so that it can make effective, if necessary, eight consecutive transfers, after which the shaft 264 moves away from the shaft 118 to allow the parts 263 to disengage from the wheels 120 and to be returned to the rest position by their springs 270.



   The shaft 266 receives its rotational movement from the shaft 150 which carries for this purpose an incomplete toothed wheel 273 (Fig. 22) meshing with a pinion 274 on the shaft 266. The ratio of the gears is such: that shaft 266 makes its two turns while shaft 150 completes approximately the last third of its revolution, while during the first two thirds of the revolution of shaft 150 during which takes place When preparing the transfers, the shaft 266 is held stationary by the two locking cams 275 and 276 carried respectively by the shafts 266 and 150.



   The backward movement of the shaft 264 is also derived from the shaft 150 (Fig. 20) on which are wedged two identical cams 277 acting on two rollers 278 each carried by one of the supports 265 of the shaft. 264. While the machine is at rest, (position shown in Fig. 20) the rollers 278 are respectively in front of the cut-out portion of each of the cams 277, which allows a spring not shown to hold. the shaft 264 moved away from the shaft 118. But as soon as the rotation of the shaft 150 begins, the cams push the rollers 278 against the action of the spring and

  <Desc / Clms Page number 30>

 move shaft 264 closer to shaft 118 to allow for preparation and completion of carryovers.

   At the end of the operation, the cams 277 again present their hollow part to the rollers 278, which allows the spring to move back the shaft 264 for the purpose of straightening all the transfer parts 262-263 which have participated in the operation.



   The backward movement of shaft 264 is used to lock all wheels 120 and, with them, discs 110 while the machine is not in use. For this purpose, a blocking bar 540 (Fig. 36) which extends along all the totalizers, is mounted between two levers 541 which can swing on the fixed guide 117, on either side of the assembly. totalizers. The levers 541 are controlled by two connecting rods 542 articulated, at 543, to the supports 265 of the shaft 264. When, the machine being at rest, the shaft 264 is moved away from the shaft 118 which carries the wheels 120, the bar 540 is engaged between the teeth thereof and locks them, while maintaining their exact alignment, against any inadvertent rotation.

   At the start of an operation, when the shaft 264 is brought closer to the shaft 118 by the means described, the connecting rods 542 push back the levers 541 with the locking bar 540 and thus disengage the wheels 120 and the discs. 110 for the duration of the operation, after which these wheels and discs are again blocked by the recoil of the shaft 264.



  Operation counters.- The different operations carried out by the cash register are counted separately by counters which are six in number: four for the operations of each of the individual totalizers A, B, D and E, one for the operations without recording (known as "exchange" operations), and one for the operations of zeroing the D-day totalizer.



   The meters may be of any suitable known construction, provided that they can be controlled by a reciprocating movement. We will not therefore describe the construction details, but only the mode of their control.

  <Desc / Clms Page number 31>

 



   All the counters 283 (Fig. 24) are fixed on the partition 103 of the machine, in the vicinity of the selection lever 290. It has already been explained that before any operation, this lever is brought into a position corresponding to the The operation to be carried out, that is to say, from bottom to top in FIG. 2, foreign exchange transaction, recording of an amount using one of the four totalizers A, B, D or
E, the selection of which is prepared at the same time, or operation to reset the day totalizer J.



   At the end of the axis 284 by which each counter is actuated is articulated a link 285 articulated on the other hand to a balance 286 (Figs. 23, 24, 25). The latter ends at the top with a point which normally engages in a notch of a fixed stop segment'287, while the lower end of the balance 286 is guided by a buttonhole, in the radial direction of the machine, on a fixed button 288. Each balance is biased towards the outside by a spring 289. The selection lever 290 carries a bogus with two ramps 291 (Figs. 23, 24) which cooperates with pins.
292 each fixed on one of the balances 286.

   When lever 290 is moved to one of its six mentioned positions, its boss
291 presses on one of the pins 292 and causes the balance 286 which carries it to descend against the action of the spring 289, until its pin 292 engages fully in a notch 293 of a sector 294 which can pivot on the central shaft 300. The balance 286 is thus coupled to the sector 294 which, when the machine is started, receives a small oscillation movement borrowed from an eccentric 295 wedged on the camshaft 200 and transmitted to the sector
294 by a double fork 296 cooperating with the eccentric 295 and oscillating around the shaft 300. The fork carries two tenons 297 between which is normally engaged the end 298 of the sector.
294.

   The oscillation movement thus transmitted to the sector 294 is transmitted by the lowered balance 286 and the corresponding rod
285 to the counter intended to count the operations of the totalizer, the selection of which is determined by the position of the lever 290.

  <Desc / Clms Page number 32>

 



   In multiple item registrations which result in the addition of items with printing of the total on a receipt, this printing must not be accompanied by the operation of a counter, because each individual item has already been counted. The counter which has remained engaged must therefore be prevented from functioning during the operation of printing the total, despite the rotation of the camshaft 200. To this end, the fork 296 is disconnected from the sector 294 by the following device:
A fork 299, the branches of which surround the shaft 200, is guided longitudinally by a pin 301 engaged in a slot 302 of the fork. At the lower end, the fork 299 has a slot 303 perpendicular to the direction of movement of the fork, and in this slot is engaged a tenon 304 carried by a lever 305 wedged on the axis 306.

   This axis can receive an oscillating movement controlled by the control lever 310, via the connecting rod 307 and the arm 308 (Fig. 27). One of the arms of the fork 299 has a profiled slot 309 in which is engaged a pin 311 carried by a connecting rod 312 pivoting on the axis 306. The same pin 311 is engaged in an eyelet 313 of the fork 296 (Figs. 23 and 25). The profile of the slot 309 is such that, during the displacement of the fork 299 caused by the manipulation of the lever 310, the spindle 311 is only affected when the latter is brought into the so-called "total ticket position". "(Fig. 2).



  In this case, the pin 311 is brought to the bottom of the V-shaped portion of the slot 309 and drives the double fork 296 to the right (Fig. 23), thus freeing the tip 298 of the sector 294 from between the tenons 297. When the machine is started for printing the total ticket, the rotation of the eccentric 295 with the shaft 200 has no effect on the sector 294 which therefore does not activate the engaged counter.



  Control lever. We have seen that before starting the machine, the control lever 310 must be placed in the position corresponding to the type of operation to be carried out. There are five gen-.

  <Desc / Clms Page number 33>

 res of operations to which correspond five positions of the control lever, namely, seen from bottom to top in FIG. 2: 1) Aims at zero of one of the individual totalizers A, B, D or E. 2) Recording of a single amount ('Single ticket "). 5) Recording of several related amounts which must then be added together ("Ticket with addition") 4) Addition of these amounts ("Total of the ticket") and 5) Reset of the day totalizer.

   It has already been described how the control lever 310 influences the direction of rotation of the control shaft 100, depending on whether it is placed either in the second or third of the above positions, which correspond to an operation d. 'recording, or in another of its positions.



  We will now describe the other effects produced in the machine by the movements of this lever.



   The lever 310 has the general shape of a plate (Fig. 27), the hub of which surrounds the central shaft 300 and the handle 310 'of which is guided in a slot in the outer sheet 105 of the machine.



  Notches in the slot allow the lever to be placed exactly in each of its five positions. However, the lower position, which corresponds to the setting to zero of one of the partial totalizers, is normally prohibited by the bolt 483 of the lock 486 placed to the right of the lever 310 (Fig. 2) and of which the key is in possession. of an authorized person. The following device prevents the operation of the machine when the lever 310 is in an intermediate position:
A roller 314 carried by an arm 315 (Fig. 27) is engaged in a sinusoidal groove 316 of the body of the lever 310. The arm 315 which is wedged on a pivot 317, is secured to a hook 435 (Fig. 33) wedged. on the same pivot 317 fixed to the partition 102 of the machine.

   Each correct position of the lever 310 corresponds to a peak of the sinusoidal groove 316, that is to say a point remote from the shaft 300. When the roller 314 is on one of the ridges, the hook 435 is raised and not not hinder the movement to the right of a plate 400, a movement which, as described later.

  <Desc / Clms Page number 34>

 thinkable for starting the machine. If lever 310 is stopped between two of its exact positions, roller 314 located between two ridges of the groove lowers hook 435 which hooks to a projection 436 of plate 400 and locks the machine.



  The safety device which has just been described also operates in the opposite direction: when operating the machine, it is not possible to move the control lever 310 because, the hook 435, being retained above the projection 436 of the plate 400 does not allow the arm 315 to pivot, so that the roller 314 remains blocked on one of the ridges of the slot 316 and immobilizes the lever 310.



   During the zeroing operations of the totalizers, the keys 215 of the machine must be blocked against any manipulation, and the "zero" pawls 234 (Fig. 17 must be raised to allow the plates 248 to leave their rest position. and perform the movements required for zeroing.



  As has been explained, a yoke 370 which extends over the entire width of the keypad is tilted counterclockwise at the start of each zeroing operation, and this movement is controlled by the lever 310, through an arm 375 which carries a roller 318 engaged in a slot 319 of the lever 310. Said movement of the yoke 370 brings it below the projections forming the end of right of the triggers 225 (Fig. 17) which serve as lower support for the trigger arcs 223 of the key mechanism, which prevents any rotation of the triggers 225 which could result from the manipulation of the keys.



  These are thus blocked for the duration of the operation.



  Conversely, if one of the keys had accidentally remained depressed, the corresponding trigger 225 would prevent the tilting of the yoke 370 and thus would not allow the control lever 310 to be brought into the position preparatory to the zeroing of a totalizer. The axis 343 which carries the yoke 370, also carries six fingers 363 (Figs. 30, 31), namely one for each "zero" pawl.

  <Desc / Clms Page number 35>

 234 with the exception of that of the numerical order of tens of thousands, the actuation of which will be described later. When yoke 370 is tilted, each finger 363 presses on a pin 234 'carried by the corresponding pawl 234, and withdraws the latter from the active position to disengage the finger 249 from each plate 248 and the toothed sectors 245.

   These movements take place both for the five sectors corresponding to the five columns of keys, and for the two sectors of the higher numerical order (thousands and tens of thousands) which do not include any keys.



  Interconnection of the control and selection levers.- It is understood that there must be a correlation between the positions of the levers 310 and 290 (Fig. 2); we will now describe the connections existing, for this purpose, between these two levers.



   Next to the selection lever 290 (Figs. 23, 24) an arc 320 is suspended from two levers 321 and 322 pivoting on journals 323 and 323 'respectively, fixed on a support 324 (Fig. 24) which runs alongside the arc 320, and is carried by the bars 211 and 212 which carry the supports 210 of the keys. Thanks to this assembly, the arc 320 can perform a slight displacement, substantially along an arc of a circle having the shaft 300 as its center. A spring 325 stretched between the support 324 and the arc 320 tends to pull the latter upwards, but the arc is retained by a hook 326 which is hooked to the pivot 327 connecting the arc 320 to the lever 322 and attached in 328 to the support 324 by a spring 329 stronger than the spring 325. The latter is therefore normally loaded. In the support 324 are embedded locks 330, one for each of the totalizers A, B, D, E and J.

   It can be seen in FIG. 2, the barrels 331 of these locks. One of the locks must be operated by its own key, to allow lever 290 to select the corresponding totalizer. Below the barrel 331 of each lock (Figs. 24 and 26) is mounted a plate 332 guided parallel to the axis of the machine by the barrel and by a button 333 fixed to the body of the lock. The narrower right part of the plate 332 is bent at a right angle ,,

  <Desc / Clms Page number 36>

 and is biased to the left by a spring 334 (Fig. 24) fixed on the other hand to the support 324. The left part of the plate 332 forms an elongated eyelet which surrounds the barrel 331 (Fig. 26) by following the contour of the barrel cut so as to form at its right part, a rib 335.

   As a result, the plate 332 prevents the rotation of the barrel, as long as it is not pushed to the right, against the action of the spring 334. For this purpose, the lever 290 has, between two notches 336 ( Fig. 26) a solid part which only pushes back plate 332 when the lever is placed in the correct position, otherwise it is not possible to turn the key in the lock.



   The cylinder 331 of the lock carries, at its lower part, a bolt 337 in the form of a cam which, when the selection lever is in a correct position, engages in a slot of this lever through one of the cutouts 338 of the arc 320. When the barrel 331 rotates, its bolt 337 lowers the arc 320 (Figs. 22,23) and is only stopped when it comes into contact with the neighboring lock.



  The downward movement of the arc 320 causes the support lever 322 to rotate slightly counterclockwise, and this movement is transmitted by a tenon 339 engaged in the bifurcated end of the lever 322 and carried by the arm 340 of a yoke 360, to the latter, which pivots on an axis 361. The yoke 360 extends over the entire width of the key compartment and ends in the vicinity of the control lever. control 310 (Figs. 27 and 30) by an arm 362 which is connected by a connecting rod 341 to one of the arms of an elbow lever 342 pivoting on an axis 350. The other arm of this lever carries a lug 344 engaged in a slot 345 of the control lever 310.

   When the arc 320 is pushed down by the bolt of one of the locks 550, the lug 344 is pushed towards the center of the machine (materialized by the shaft 300) and allows, by sliding in the slot 345 to move the lever 310, which would not have been possible without actuating one of the locks 330 of the individual totalizers.



    --However, the length of slot 345 is limited to

  <Desc / Clms Page number 37>

 so that the lever 310 can only be moved between its first and fourth position (seen from below in Fig. 2). In fourth position (1! Ticket total ") the lug 344 reaches the bottom of the window 345 and the lever 310 cannot therefore be brought to its fifth position preparatory to the zeroing of the day totalizer J In order for this to become possible, it is first necessary to push the selection lever 290 fully upwards, which corresponds to the selection of the D-day totalizer. Shortly before the end of this movement, the lever 290 strikes a latch 346 (Fig. 23) which the arc 320 bears on its side, and the arc is lifted against the action of the strong spring 329.

   Then only the first cutout 338 (from above) of the arc 320 comes in front of the lock 331 of the totalizer J and allows the bolt 337 of the latter to immobilize the lever 290 and the arc
320. The upward movement of the arc 320 is transmitted, as described (but in reverse), by the lever 322, the yoke 360, the connecting rod 341 and the elbow lever 342 to the lug 344 which is , st, therefore, completely disengaged from the slot 345 of the lever 310 and allows the latter to be placed in its fifth position which corresponds to the setting to zero of the day totalizer J.



   As already described, during the resetting of individual totalizers, the first six "zero" pawls 324 are reversed by as many fingers 363 as the yoke 364 carries. For the purpose of resetting the day totalizer J which has seven discs 110, it is also necessary to move back its "zero" pawl which corresponds to the higher numerical order (tens of thousands), and this is done by a latch 388 (Fig. 34) fixed on the lever. 322 supporting the arc 320. This latch pushes back the hook 324 in question during the rotation of the lever 322, caused by the movement of the selection lever 290 preparatory to the zeroing of the day totalizer J.



   In order to avoid errors in the handling of the locks and in the installation of the amount to be registered, measures are taken to make it impossible to actuate the locks when one or more of the keys are pressed, and to remove the key from the lock. '' an individual to- talisteur if, at the end of the operation, one or more

  <Desc / Clms Page number 38>

 keys remained pressed. For this purpose the yoke 360 (Figs. 30, 31) is flanked, at the left end, by an arm 365 carrying a roller 366 which normally occupies, when none of the locks is manipulated, a position above of the nose 369 of a lever 367 integral with the yoke 370. When the cylinder 331 of the lock of one of the individual totalisers is turned, the yoke 360 pivots, as already described, in the direction of clockwise.

   The roller 366 pushes back the nose 369 of the lever 367 while descending and thus gives the yoke 370 a rapid oscillation. When the roller 366 descends below the nose 369, the yoke 370 returns to its place under the action of the spring 371 which connects it to the yoke 364 (Fig. 32), the latter being immobilized, as explained, by the roller 318 (Fig. 32 and 27) engaged in slot 319 of control lever 310.The same oscillation of yoke 370 occurs when turning the cylinder of a lock in the opposite direction to remove the key, the roller 366 acting in this case on the lower inclined surface of the nose 369.



  Now, the yoke 370 serves to block the keys by acting on the protruding nose of the triggers 225 (Fig. 17) and, when a key is pressed, it is impossible to move the yoke back. It follows that, if one wanted to turn the cylinder of a lock when a key is pressed, the yoke 370 would strike the nose of a trigger 225, so that the roller 366 could neither descend nor rise. , and it would be impossible to manipulate the lock.



  Operation without intervention of totalizers.- In certain cases, for example for control purposes, or for a simple exchange operation etc., the machine must be operated without recording or resetting, therefore without any totalizers is activated, and without having to use the key of one of the totalizers.

   To this end, the selection lever 290 is brought into its lower position, called "change" in FIG. 2; in this position of the lever 290 (Figs. 23 and 31), a pin 372 fixed on a projection of the body of the lever, engages in an inclined notch

  <Desc / Clms Page number 39>

 
368 which has, at its upper part, the lever 367, integral with the yoke 370, and causes the latter to tilt to the left (Fig. 23), where it is immobilized. Therefore, as already explained, the keys
215 are locked against manipulation, and conversely, when a key is depressed, yoke 370 cannot swing to the left and lever 290 cannot be moved to the "change" position.



   On the other hand, it is only possible to place the lever 290 in the "change" position when the control lever 310 occupies the 2nd. or 3rd. position ("single ticket" or "ticket with addition"). In fact, when the lever 310 is in another position, the yoke 364 is tilted, as we have seen, in the opposite direction to that of clockwise (Figs. 27, 31). The left arm (Fig. 30) of the yoke 364 is flanked by a finger 373 which, by tilting with the yoke 364 comes into the path of the pin 372 of the lever 290 and prevents the latter from engaging in the yoke. 'inclined notch 368 of lever 367.



   The latter, together with the yoke 370, is also tilted to the left, so that the pin 3723, upon striking it, prevents the lever 290 from lowering to the "change" position. Conversely, when the lever 290 is in this position, it is not possible to put the control lever 310 in the 1st., 4th. or 5th. position, because the pin 372, placed in front of the finger 373 opposes the movement of the yoke 364 to the left and, therefore, the movement of the lever 310.



   As has been said, the starting of the machine begins with an escape, to the right, of a plate 400 (Fig. 33), the functions of which will be more fully described later; for this it is necessary, that a lock 401.qui retains it by hooking to a shoulder of its lower face, is lowered, and this, whatever the operation that the machine must perform.



   When it is a question of a recording, or of the resetting of one of the individual totalizers preceded by the manipulation of one of the locks 330, this manipulation has the effect, as already described, of causing a pivoting movement, in the opposite direction of acute

  <Desc / Clms Page number 40>

 the of a watch, of the elbow lever 342 (Figs. 27 and 33). The left arm of this lever presses on a lug 348 carried by one of the arms 347 of a yoke 349 pivoting on the axis 350. The other arm 351 of the same yoke, which ends in a fork (Fig. 33. ) embraces a pin 402 carried by the latch 401.

   A spring, not shown, attached to the partition 102 and to the yoke 349 maintains the arm 347 thereof in contact with the elbow lever 342, so that, upon manipulation of one of the locks 330, the movement of the lever 342 is transmitted to the latch 401 which descends and releases the plate 400. When the operation envisaged is the resetting of the day totalizer D, with a view to which the control lever 310 is placed in its highest position, it is this lever itself which, by pushing back the lug 348 by its inclined surface 352 (Fig. 27), rotates the yoke 349 and thus lowers the latch 401.



   Finally, when the machine has to operate without recording or zeroing for a so-called "change" operation, the selection lever 290 is first brought into the lower position corresponding to this type of operation. Going down, the lever 290 strikes a catch 353 (Fig. 23) of the arc 320 and causes the latter to descend, which causes the same effect as the manipulation of one of the locks, namely: pivoting of the support lever 322 and yoke 360, translation of the connecting rod 341 (Fig. 33), pivoting of the elbow lever 342 and of the yoke 349 with its arm 351, and lowering of the lock 401. During these movements, the roller 366 of the arm 365 soli- The yoke of the yoke 360 (Figs. 30 and 31) is placed below the nose 369 of the lever 367, which retains the lever 290 in its lower position, despite the tendency of the spring 325 to raise the arc 320.



  The notch 368 at the top of the lever 367, in which the pin 372 of the lever 290 is engaged, has a shape such that it allows the lever 290 to go up a little, which causes a slight rotation of the lever 367, with the yoke 370 , under the action of spring 371 (Fig.



  32), in a clockwise direction, so that the nose

  <Desc / Clms Page number 41>

 369 advances above the roller 366. In order to be able to raise the lever 290 in a position other than that called "change", it is necessary that the arc 320 and the yoke 360 with the arm 365, as well as the lever 367 return to their rest position. The roller 366 cannot however rise above the nose 369, by pushing the lever 367 back, under the sole action of the spring 325 acting on the arc 320.



  To raise the arc 320, use is made of a hook 354 pivoting on an axis 355 carried by the lever 290. When the latter is in the "change" position, the hook 354 hooks onto the pin 353 of the lever. arc 290, under the action of a spring 356. While the lever 290 is raised, the hook 354 drives the arc 320 which causes the roller 366 to rise above the nose 369. The arc 320 protrudes. slightly, upward, his. normal position, but the strong spring 329 then pulls it down and moves the hook 354 back against the action of its spring 356, after which the arc 320, disconnected from the lever 290, is returned by the spring 329 to its position rest.



  Automatic control of the control lever.- The most frequent operation of the machine is that of a simple recording, which requires that the control lever is in its second position from below, (Fig. 2); however, this lever is often also in the fourth position, to add and print the total of several recordings made. In order to make the work of the machine more expeditious, the lever 310 is automatically returned to its second position, at the end of each operation during which it was in the fourth position.

   For this purpose, the body of the lever 310 carries, at the rear of the machine, a small cam 376 (Figs. 27, 28, 29) in the plane of which is, on the other hand, a groping 377 suspended from it. two levers 378 and 379 pivoting respectively on axes 380 and 381 which are carried by a support 382 mounted on a fixed frame 600. The lever 378, which is bent, carries at the end of its other arm a pin 383 which , by passing through an opening in the support 382, engages in the forked end of one of the arms of an elbow lever 384 pivoting on the axis 381.

  <Desc / Clms Page number 42>

 



  The other arm, also forked, of the angled lever 384 controls a lug 385 fixed to a finger 386. The latter can slide, by a buttonhole 387, on a pin 637 carried by the frame 600. The finger 386 which is normally located fully clockwise, as shown in Fig. 27, is also supported by the end of a link 389 articulated, at the other end, to an arm 390 capable of pivoting on the axis 637. When the control lever 310 is brought into its fourth position, the cam 376 meets the feeler 377 and pushes it back to the right which, by the cooperation of the bent levers 378 and 384, causes the latter to pivot clockwise, against the tension of a spring 391.

   Fn swiveling, the lever 384 drives the lug 385 to the left with the finger 386, until the axis 637 is in the right end of the buttonhole 387. In this advanced position, the finger 386 by pivoting on the axis 637 may strike a tenon 392 fixed to the body of the control lever 310 when the finger receives an upward impulse. The arm 390 connected to the finger 386 by the connecting rod 389 is controlled by a forked connecting rod 594 which carries a roller 395 cooperating with a cam 393 wedged on the camshaft 200. This shaft, as already said, makes a complete revolution. every time the machine is operated.

   The profile of the cam 393 is such that at the start of the operation the connecting rod 394 is slightly raised and the finger 386, being in the forward position to the left, hooks onto the pin 392 and remains so for almost the entire duration. of machine operation. Towards the end of the operation, the cam 393 abruptly lifts the connecting rod 394 and, with it, the finger 386. This movement transmitted by the tenon 392 to the lever 310, has an amplitude such that this lever, by pivoting on the shaft central 300, is returned to its second position that it must occupy for a new registration operation. At the same time, the spring 391 returns all the components described in their rest position.



  Motor organs. - We have described so far, in addition to the actual totalisers, the arrangement and operation of the

  <Desc / Clms Page number 43>

 the machine involved in the preparation of an operation.



   We will now describe the motor members which are used to start the machine in order to make effective the operation prepared by the means described.



   The motive force actuating the machine can be supplied, which is the normal case, by an electric motor housed therein, or else, in the event of an electric current fault, by the operator himself. even acting on a crank. The two controls can be used at will, without the intervention of any coupling.



   The electric motor 501 (Figs. 36 and 37) which may be of any suitable type, and which is preferably a single phase auxiliary pole motor, operating at 40-50 per./sec., And provided with of a speed reducer 502, is suspended, by arms
503 (Fig. 37) to the bearing 504 of the motor shaft 500, and its gear 505 engages the idler toothed wheel 506 on the shaft 500.



   The motor 501 also rests elastically on the plate of the machine 101 (Fig. 36) with the interposition of rubber blocks 109.



   By virtue of this floating arrangement, the gears 505 and 506 remain in constant mesh smoothly despite the slight oscillations of the motor which may occur during operation as a result of rapid variations in resistive torque.



   The coupling between the toothed wheel 506 and the shaft 500 is produced, for the duration of the operation, by a roller clutch consisting essentially of a cup 507 integral with the toothed wheel 506 and a disc 508. wedged on the shaft 500. Three rollers 509 (Fig. 36) each housed in a cutout; wedge-shaped disc 508 establishes the connection between it and the cup
507 when they are wedged between these two parts as a result of the clockwise rotation of the bowl
507 driven by the engine.

   The jamming of the rollers 509 is further promoted by springs 510 housed in the body of the disc 508.

  <Desc / Clms Page number 44>

 
On the other hand, the shaft 500 carries a toothed wheel 511 which, by means of the toothed wheels 512 and 513 wedged on the shaft 150 is controlled by a pinion 514 wedged on a shaft 515. The latter, which comes out of the machine on the right side of it (Figs.l, 35 and 36) carries a crank 516 acting through a roller clutch 517-518, which has two rollers, but is otherwise similar to that between the motor and the shaft 500. It will therefore be understood that the shaft 500 can be driven either by the motor 501 or by the crank 516.



   Control shaft 500 makes one complete revolution per operation, which requires, in the case of manual control, two complete revolutions of crank 516. If the control is carried out, as is normal, using the motor, the rotation of the shaft 516 is limited to one revolution by the following mechanism: pawl 519 "(Figs. 36 and 38) with two jaws 521 and 522 can pivot on a pin 520 fixed to the partition 102. The nozzle 521 can engage in a notch of a disk 523 fixed on the shaft 500, and prevents the latter from turning using the crank 516 as long as the machine is not released as explained below .

   The nose 522 can engage in a notch of a flat disc 524 (Fig. 37) mounted on the hub of the disc 523 and carrying, perpendicularly to its plane, three pins 525 each entering a central hole of each clutch roller 509.



  The nose 522 maintains the disc 524 in the disengaged position, the pins 525 pushing the rollers 509, against the action of the springs 510, in the widest part of the notches in the disc 508.



  Between the disc 524 and the disc 523 are still mounted on the hub of the latter; a detent disc 526 (Fig. 39) also cooperating with the nose 522 of the pawl 519 and a cam 527 which is attached thereto, finally a contact breaking cam 528 (Fig. 40) assembled in such a manner adjustable to disc 523. Cams 527 and 528 cooperate with a two-arm contact lever, pivoting on a fixed axis 529 (Fig. 36). One of the arms, 530 of this lever carries a roller

  <Desc / Clms Page number 45>

 531 which can engage in the notches of the two cams 527 and 528 at the same time; the other arm 532 of the contact lever ends in a rod of insulating material 533 which brings together, when the arm 532 pivots clockwise, two electrical contacts 534 and 534 '.

   The contact cam 527 integral with its detent disk 526 is subjected to the action of a spiral spring 535 (Fig. 39) which tends to make it rotate clockwise, in advance of the axis. rotation of the motor shaft, but this movement is normally made impossible by the pawl 519, the nose of which 521 retains the disc 526 in the position where the roller 531 of the arm 530 is engaged in the hollow of the cam 527 at the same time than in that of the cam 528 integral with the stop disk 523.



   To start the machine, it is therefore necessary first of all to reverse the pawl 519 and for this purpose the large release button 440 is pressed (Figs. 2 and 33). The key 440 surmounts a rod 441 guided, through a fixed block 442 towards the center of the machine. The end of the rod 441 carries a lug 444 engaged in the forked end of a pawl 450 pivoting on a pin 449 and resting, by its other end, against a shoulder 458 of the plate 400 which, as already said, must escape to the right (in Fig. 33) at the start of machine operation. When the trigger button 440 is depressed against the action of a strong enough spring 443, the pawl 450 pivots clockwise and disengages the plate 400.

   It should be noted that it is necessary to release the plate 400 by pressing the button 440 even when it is desired to operate the machine by hand by means of the crank 516.



  It will be remembered that the latch 401 which also retains the plate, was withdrawn during the preparatory movements of the selection 290 and control levers 310, so that the plate 400 can escape to the right, under the action of 'a powerful spring 403 attached to the plate at 438. In its movement to the right, the plate 400 which is guided by a large notch 429 embracing the central shaft 300 pushes back a connecting rod 480 and rotates, around a

  <Desc / Clms Page number 46>

 axis 431, one of the two arms 432 of a yoke 433, the other arm 434 of which (Fig. 36) is connected to a lever 536 fixed on the axis 520 which carries the pawl 519.

   The latter is thus lifted and releases the disks 523, 526 and 524; under the action of the spring 535, the cam 527 turns by a certain angle, advancing with respect to the subsequent rotation of the shaft 500, pushes the roller 531 back, rotates the lever 530-532 and closes the contact 534- 534 ', which starts the engine. At the same time, the spindle disc 524 allows the rollers 509 to engage, so that all parts start to rotate with the shaft 500.



   Shortly before the completion of the complete revolution of the shaft 500, the plate 400 is returned, as described below, to its rest position and, by causing the connecting rod 430 in this movement to the left, it causes the lowering. of the pawl 519. This first meets the notch of the disc 526 which is immobilized while the shaft 500 is still turning and thus tightens the spring 535. The roller 531 of the lever arm 530 nevertheless remains in the out position because , in front of it, only the cam 527 presents its notch to it, while the contact breaking cam 528 is still present by its circular face, so that the electrical circuit still remains closed and only opens completely at the end of the operation, when the size of the cam 528 is also in front of the roller 531.



  At the same time, the pin disc 524 is immobilized by the nose 522 of the pawl 519 and its pins 525 push back the rollers 509 to effect the disengagement while the shaft 500 is stopped by the pawl 519 whose nose 521 falls back into the 'notch of disc 523. In this way, the inertia of the motor and its speed reducer does not affect the shaft 500 because, immediately after stopping the latter, the cup 507 can rotate freely up to 'when the engine is stopped.



   As has been explained, the rotation of the motor shaft 500 is transmitted, on the one hand, to the camshaft 200, by the gears 511, 537, 538, and from there to the shaft. 100 carrying the totalisers;

  <Desc / Clms Page number 47>

 on the other hand to the shaft 150, by the gears 511 and 512.



  Safety plate.- We have already said that at the start of each operation, the plate 400 released by the manipulation of the large release button 440, escapes to the right under the action of the spring 403 (Fig. 33). and thus starts the engine 501.



   The spring 403, attached to the plate 400 at 438 is fixed at the other end to a connecting rod 404 articulated at 405 to an arm 406 which can pivot on the axle 193 and which is normally held stationary by a roller 407 which it carries and which is engaged in the groove 408 of a plate cam 409 fixed on the shaft 200. The connecting rod 404 is assembled to the plate 400 by means of a button 410 fixed to the plate and engaged in a buttonhole 411 of the connecting rod. When the plate escapes to the right, its stroke is limited by the length of the buttonhole 411, the connecting rod remaining stationary.



   During its movement to the right and its return movement, the plate 400 performs yet other functions which will now be described. It has been said that after the preparation of a recording and throughout the duration of the latter, the keys 215 must remain locked by the locking arcs 229 which do not allow a new key to be pressed, nor release the pressed keys. The arcs 229 are controlled from the plate 400 which coiaports, for this purpose, a curved groove 412 in which can slide a pin 413 carried by a fork 414 (Fig. 33). The latter is guided, at one of its ends, on the central shaft 300 and articulated, at the other, to an arm 415 wedged on an axis 416 supported by the partition 102 and by a bracket 417 fixed to the partition 103.



  The escape of the plate 400 to the right has the effect of lifting, by the spindle 413, the fork 414 and of rotating the arm 415 and the axis 416 in the opposite direction to that of clockwise. Two identical arms 418 wedged at the ends of the axis 416 carry a rod 419 which extends over the entire width of the keyboard

  <Desc / Clms Page number 48>

 keys and engages, as a result of the described movement in which it participates, in the notches 420 (Fig. 17) of the rods 230 supporting the upper ends of the locking arcs 229.



   These are thus raised and block all the keys for the duration of the operation. When, at the end of the operation, the plaque
400 is returned to the left, to its rest position, all the movements which have just been described are reproduced in the opposite direction, and the keys are thus released with a view to preparing a new recording.



   The return of the plate 400 to its rest position is controlled by the cam 409 (Fig. 33) wedged on the shaft 200 which makes one revolution during each operation. Shortly before the end of the turn, the groove 408 of the cam 409 presents to the roller 407 a re-entrant part which forces the arm 406 to pivot rapidly, around the axis 192, first to the left, then to the right. . In its movement to the left, the arm 406 is accompanied by the connecting rod 404, the plate 400. and the spring 403 which therefore does not oppose the return of the plate 400 to the left. The plate in this return movement extends somewhat beyond its normal position, which allows the pawl 450 to drop past the shoulder 458 of the plate.

   While the cam 409 completes its turn, the re-entrant part of the groove
408 slightly exceeds the fgalet 407, which brings the arm 406 and the connecting rod 404 a little to the right, to their rest position, and binds the spring 403. As a result, the plate 400 is also brought back a little to the right and is stopped in its normal position when its shoulder 'rests 458 butts against the pawl 450.



   During the return movement, to the left, of the plate
400, which marks the end of an operation, the keys 215 which were pressed for the recording operation should be pulled out. For this purpose, the connecting rod 404 is articulated to a connecting rod 421 articulated, on the other hand, to a balance 422 (Figs.



   33 and 33a) pivoting on the axis 423 and carrying, at its free end, a small plate 424. This plate 424 has a notch

  <Desc / Clms Page number 49>

 425 in which., Is. engaged a pin 426 which passes through an opening of a connecting rod 427 articulated to a lever 428 integral with a yoke 374 which can pivot about the axis 361 and extends over the entire width of the keyboard. When, towards the end of the operation, the connecting rod 404 is moved to the left under the action of the roller 407 controlled by the cam 409, this movement rotates, in an anti-clockwise direction, yoke 374 (Figs. 33 and 17) which strikes the triggers 225 (Fig. 17).



  These, by pivoting, raise the trigger arcs 223, the pins 222 of which release the stems 221 from the keys 215 and allow all the keys which had been pressed to rebound under the action of their return springs 218. Immediately after that, when the connecting rod 404 withdraws a little to the right, the yoke 374 and, with it, the detent arcs 223, return to their normal position.



   It may happen accidentally that the person using the machine keeps his hand on key 440, which could trigger a second operation. To deal with this eventuality, the following safety device is provided.



   Next to the pawl 450 is mounted on the pivot 449 a counter-pawl 452 provided with a curved groove 453 in which a lug 451 of the pawl 450 can slide. A spring 454 stretched between the pawl 452 and the pawl 452. lug 451 maintains the latter at the left end of the groove 453 and holds the pawl 452 raised. This pawl ends in a hook offset laterally so as to be in the plane of the plate 400, a little above a shoulder 455 thereof. When the trigger button 440 is pressed, the counter-pawl 452 is applied to the shoulder 455.



  If key 440 were to remain depressed while plate 400 returns to the left at Operation Complete, counter-pawl 452 would drop past shoulder 455 of the plate as the plate protrudes a little to the left, as described. , its normal position, and

  <Desc / Clms Page number 50>

 would make it impossible to trigger a second operation unexpectedly. When the button 440 is released, the latter rises under the action of its spring 443, lowers the pawl 450 a little in front of the shoulder 458 of the plate, raises, by means of the spring 454 the counter-pawl 452 and thus allows the plate 400 to resume, under the action of the spring 403, its normal position determined by the meeting of the shoulder 458 with the pawl 450.



  Repeat Key - As has been said, the keys pressed for a recording operation are released and return to their original positions at the end of the operation. However, if it is desired to record the same amount several times consecutively, it is desirable to leave the keys pressed so that it is sufficient to press the release key 440 at each subsequent operation, without any further movement. preparatory. For this purpose, the machine has a key 460, called "repeat key", located to the right of the keypad, below key 440 (Figs. 2 and 33). The key 460 surmounts a rod 461 guided along the partition 102 in the slot of a block 462 and provided with a return spring 463.

   Near its lower end, the rod 461 forms a heel 464, the lower inclined face of which pushes back, when the key 460 is pressed, a lug 468 integral with a lever 469 which pivots on the pivot 449, and that a spring of reminder, not shown, tends to pull down. In a groove 470 of the lever 469 is engaged a pin 471 fixed to one of the arms of a fork-shaped balance 472 (Fig. 33a) guided vertically by the end of the shaft 423. its lower end, the balance 472 carries the pin 426 which, as already said, passes through a hole in the connecting rod 427 serving to transmit to the yoke 374 the movement which is used for the. end of an operation, to release the pressed keys.

   It will be understood that when the repeating key 460 is pressed, the movement imparted by the rod thereof, to the lever 469, has the effect of lifting the balance 472 with the pin 426, to cause the latter to come out. the notch 425 of the plate 424 and thus disconnect the connecting rod 421

  <Desc / Clms Page number 51>

 of the connecting rod 427. Under these conditions, the yoke 374 not receiving any pulse at the end of the operation, does not release the pressed keys, and this as long as the repeat key 460 remains pressed. In order to avoid an unexpected rebound of the latter, its heel 464 has a notch 466 in which the lug 468 engages, under the action of a spring not shown, as soon as the key 460 is fully depressed.



  * Key release mechanism.- When you no longer wish to repeat the recording of the same amount, you must release both the repeat key 460 and the keys 215 on the keyboard. A button 475 is used for this purpose located to the right of the machine, in front of the crank 516 (Figs. 1 and 35). This button 475 is carried by an articulated rod 476, at the rear of the machine, to one of the three branches of a Y-shaped lever, 477, pivoting on an end of axis 478 fixed to the partition 102. At the lower end of the lever 477 is articulated a connecting rod 479, the opposite end of which has a slot 480 in which is engaged a pin 481 which the lever 428 carries, integral with the yoke 374.

   When the operator. pulls towards the front of the machine (that is to say towards the left in Fig. 35), the button 475 with the rod 476 which is guided, at its front end by a slot 482 and a tenon, fixed 483, this movement causes the lever 477 to pivot around the axis 478. The connecting rod 479 moves rearwardly, drives the lever 428 integral with the yoke 374 and causes the latter to pivot counterclockwise. 'a watch, which has the effect, as already described, of releasing the pressed keys 215, via the triggers 225 (FIG. 17). In its pivoting movement, the lever 428 drives the connecting rod 427 to the left with the spindle 426 and the lower end of the balance 472 (Fig. 33).

   The upper end of this balance describes a circular movement to the right, around the axis 423 as its center, in which the spindle 471 takes part, trapped in the curved slot 470 of the lever 469. The curvature of the slot 470 is less than that

  <Desc / Clms Page number 52>

 of the path of the spindle 471, so that the lever 469 is slightly raised and its lug 468 comes out of the notch 466, which allows the key 460 to return to its normal position, under the action of its spring return 463. In order that the lever 469 is lifted more easily, against the action of its return spring, the connecting rod 479 carries a finger 484 (Figs. 33 and 35), the inclined upper surface of which comes below the spindle. 426 and pushes it slightly upwards.

   After releasing the button 460, when the operator releases the button 475, all the parts are returned to the position corresponding to the normal operation of the machine: the lever 469 with the balance 472 are pulled down, by the return spring not shown of the lever 469 until the pin 426 engages in the notch 425 of the balance 422; the linkage 479-477-476, as well as the yoke 374 and its lever 428 are returned to their place by a spring 485 stretched between the latter lever and the finger 484 of the connecting rod 479.



   The mechanism described is also used when it is necessary to correct, before starting up the machine, an error in the handling of the keys: pulling the button 475 releases the keys 215 already pressed. The lug 468 being outside the notch 466 of the repeat key which is not pressed, this key is in this case not affected by the handling of the button 475.



   When, at the end of a recording operation, the pressed keys 215 are released in the normal way, by the recoil to the left of the plate 400, the movement transmitted to the lever 428 by the connecting rods 421 and 427 is exerted. no reaction on all of the components which have just been described because, during the oscillating movement of the lever 428, its pin 481 simply slides in the slot 480 of the connecting rod 479, without moving the latter or the related components .



    - Releasing the keys using button 475 must not be

  <Desc / Clms Page number 53>

 be done when the machine has not yet been started, that is to say when the plate 400 has not yet moved to the right in FIG. 33. In order to avoid false maneuvers, the third branch of the Y-lever 477 carries a stopper 474. If the button 475 is pulled when the plate 400 has already escaped to the right, the stopper 474, by pivoting with the lever 477 about the axis 478, hits the lower horizontal surface of the wide notch 429 by which the plate 400 is guided on the shaft 300 and prevents the operation of the key release mechanism , until the plate 400 returns to its rest position, after the completion of the operation.



  General lock - The starting of the machine, which in any case requires the movement of plate 400 to the right, can be prohibited using the general lock 486 which is to the right of the keypad ( Figs. 2 and 35). The rotary cylinder of this lock carries three arms 487, 488 and 489. When the lock is closed, the arms move into the position shown in FIG. 35: The arm 487 is placed below the lug 402 of the latch 401 which retains, from below, the plate 400 and therefore prevents the starting of the machine.

   At the same time, a pin 490 fixed to the arm 487 comes into contact with an integral lever 491, through the part 492 (Figs. 30 and 32) of the yoke 370; the pin 490 thus causes the yoke 370 to tilt which locks all the keys 215 in the rest position, so that it becomes impossible to manipulate them. The second barrel arm 488, which has the shape of a hook, hooks onto a pin 493 of the connecting rod 479 and thus prevents the operation of the key release mechanism using the button 475. -Finally , the third arm, 489 is articulated to a rod 494 articulated on the other hand to a lever 495 pivoting on the fixed pivot 483 (Figs. 33 and 35). A pin 499 carried by the lever 495 comes, while the lock is being closed, to strike a heel 496 of a locking arc 497 which is thus raised.

   The arc 497 is guided by two buttons 498 and 498 'engaged respectively, in -. A notch and a slot of the arc which is normally drawn.

  <Desc / Clms Page number 54>

 down by a spring, not shown. The arc 497 has, on its back, two notches 446 and 457, normally situated next to the rods 441 and 461 of the trigger button 440 and of the repeat button 460. These rods each have a lug, respectively 445. and
467, which enter the notches 446 and 457 when the keys 440 and 460 are pressed. But when, by closing the lock, the arc 497 is raised, the notches move away from the rods 441 and 461, so that 'it becomes impossible to press any of the keys 440 and 460.

   Although the movement of the selector lever 290 is still possible, except in the lower position, the locks 331 of the totalizers cannot be manipulated, because of the blocking of the latch 401 of the plate 400. Thus, any manipulation not authorized checkout is prohibited by the general lock 486.



   Variant. - According to a modified form of control of the totalizers, use is made, in each regulating mechanism, of a single toothed sector, instead of the two toothed sectors 240 and 245 described above. In this modified construction, the rotation of the control shaft always starts in the same direction, whatever the type of operation to be performed. If the operation is a resetting of a totalizer, the selection of the latter becomes effective from the start of the rotation of the control shaft which drives the totalizer discs in its forward stroke; during the stopping of the shaft, the totalizing discs move away from their respective drivers, and the shaft returns to its normal position without bringing back the discs which it has driven on the way.

   On the other hand, if the operation is a recording, the forward stroke of the control shaft is carried out "empty", without driving totalizing disks; these are brought into engagement with their respective drivers only during the short stop of the control shaft which drives them during its return rotation. This simplified operation of the body can be achieved thanks to some modifications in the selection mechanism, in the control of the control shaft and the shaft.

  <Desc / Clms Page number 55>

 central, and in the arrangement of the operating mechanisms. These modifications will now be described.



   Instead of the profiled groove cam 151 (Fig. 8), the camshaft 150 carries two cams 550 and 551 (Figs. 44 and 45) with which two curved levers 554 and 555 cooperate, each of which carries a roller. , respectively 552 and 553 which rolls on the periphery of the corresponding cam 550 or 551. The two levers 554 and 555, which can, under the influence of the cams 550, 551, pivot on a fixed pivot 556, end, each, by a finger 557, the meeting of which with a lug 558 (or 559) of the cam 550 (or 551) has the effect of returning to its normal place that of the levers 554 or 555 that the cam 550 or 551 had rotated . At the opposite end, each of the levers 554, 555 ends in an enlarged part (Figs. 46 and 47) in which a slot is made, respectively 560 and 561.

   In these two slots is engaged the end of the same lever 562 wedged on the pin 154 which is mounted in the fixed support 155 so as to be able not only to oscillate, but also to slide to a small extent.



   The axis 154 receives its sliding movement from a rocker 565 (Fig. 44) which can pivot on a fixed pivot 566, and the forked end of which is engaged in a groove 564 which the axis presents to. . its left end. The rocker 565 carries two rollers 567 and 568 which cooperate alternately with a cam 569 fixed on the shaft 168. An oscillation imparted to the shaft 168 (by the operation of the control lever 310, as already described with reference to FIG. 10), therefore results in a displacement of the axis 154 to the left or to the right, depending on whether the cam 569 pushes the roller 567 or 568 of the balance 565.



   The oscillating movement of the axis 154 is imparted to it by the lever 562. The slots 560 and 561, in which is engaged the end of the lever 562, which accompanies the axis 154 in its sliding movement, are profiled in such a way. way that, placed on the left

  <Desc / Clms Page number 56>

 in the slots (Fig. 46) the end of the lever 562 is only lifted by the curved lever 554, when the latter oscillates under the influence of the. cam 550. On the other hand, when the end of the lever 562 is placed, by the sliding of the axis 154, in the right part of the slots 560 and 561 (Fig. 47), it is the curved lever 555 which only the lever 562 can be lifted, thus causing the axle 154 to oscillate.



   The bosses of the cams 550 and 551 have such angular positions, with respect to the shaft 150, that when the pin 154 is in its right-hand position, which is the case when the control lever 310 is placed in the right position. a position preparatory to a zero-setting operation, the axis 154 receives an oscillation, through the intermediary of the cam 551 and the levers 555 and 562, as soon as the machine is started up, and is returned to its normal angular position when the control shaft 100, after having turned one revolution, is stopped before its return rotation. The oscillation of the axis 154 has the effect of making effective the selection of the totalizers intended to participate in the operation, as described with reference to Figs. 7 to 12.

   On the other hand, when the control lever 310 is moved for a recording operation, this movement is transmitted by the rack 169 (Fig. 10) to the shaft 168 and by the cam 569 and the balance 565 to the shaft. pin 154 and lever 562, the end of which is placed in the left part of slots 560 and 561 (Fig. 46). In this case, it is the curved lever 554 which oscillates the axis 154 when the drive shaft 100 is stopped after its forward rotation. At this time, the selection of the totalizers to participate in the operation becomes effective, and their discs are driven during the return rotation of the drive shaft 100.



   From the foregoing, we will therefore start the rotation of the control shaft 100 always in the same direction, which makes it unnecessary to control it by means of the device for changing the direction of travel (Figs. 13 to 16). ). In the modified construction,

  <Desc / Clms Page number 57>

 the rotation of the control shaft derives, as before, from two cams 187 and 188 (Fig. 41) wedged on the camshaft 200 and acting on the two rollers 190 and 191 of a double lever 189 which can pivot on the axis 192. At its upper end, at 193, the lever 189 is articulated to two connecting rods 571 and 572. The connecting rod 572 controls, by a button 573, a toothed sector 574 which is loose on the central shaft 300 and meshes with the pinion 202 wedged on the control shaft 100.

   The pinion 202 on the other hand meshes with a pinion 575 which is in mesh with a toothed sector 576 wedged on the central shaft 300. In this way, when, when the machine is started, the shaft to cams 200 make a complete revolution with its cams 187 and 188, these, in accordance with their profile, impart to the control shaft its rotation of one revolution followed, after a short stop, by a rotation one turn in the opposite direction; and at the same time the central shaft 300 receives its usual movement. So that there is no delay in the rotation of the central shaft 300 relative to that of the control shaft 100, the connecting rod 571 attacks the toothed sector 576 by the button 577 and thus corrects the play of the components. transmission which could appear towards the end of the race.



   At its lower end at 578, the arm of the toothed sector 574 is articulated to a connecting rod 590 which controls, by a button 591, the frame 643 which intervenes in the operation of the indicator, as described below.



   As already stated, the modified control of the control shaft 100 makes it possible to replace, in each regulating mechanism, the two toothed sectors (240 and 245), by a single toothed sector 592 (FIG. 48) which participates in all the changes. operations, both recording and resetting. Furthermore, the operation of the regulatory mechanism is substantially the same as previously. In each of its movements, the toothed sector 592 is accompanied by the plate 248 which is now secured to the toothed sector 592 by two spacers 593 (Figs. 48 and 49). The locking device, with its members 249 to 255 is the same as that

  <Desc / Clms Page number 58>

 previously described, with reference to FIG. 17.



   The movements of the mechanisms according to Figs. 41 to 50, on the one hand during a recording operation, on the other hand during a zeroing operation, are as follows:
Prior to starting the machine for recording, the selection lever 290 is operated to select the individual totalizer intended to participate in the operation, and the control lever 310 which is placed in the po 'position corresponding to the type of operation, namely "Ticket-, simple" or "Ticket with addition" (Fig. 2).

   The movement of the lever 510 results in a rotation of the shaft 168 (Fig. 44) such that the cam 569 pushes the balance 565, with the axis 154 and the lever 562, to the left, so that the end lever 562 is placed on the left in slots 560.561 (Fig. 46) and can only be lifted by curved lever 554.



     When the machine is started up, the shaft 200 (Fig. 41) begins to turn in the direction of the arrow, and almost immediately its cams 187 and 188 make the toothed sector 574 rotate to the left then , after a short stop, bring it back to the position shown. The pinion 202 wedged on the control shaft 100 thereby transmits to the control shaft a rotation of one complete turn in the direction of clockwise then, after the short stop, of a turn in the direction. reverse. At the same time, by the pinion 575, the toothed sector 576 wedged on the central shaft 300, receives a movement similar to that of the sector 574, but in the opposite direction.

   The control shaft 100, the drivers 138 of which are engaged in the grooves 159 of the toothed wheels 137, drives the latter and, with them, the toothed sectors 592 of all the operating mechanisms. Each time one of the fingers 249 encounters the stem of a depressed key (or a zero pawl) during the forward stroke, it interrupts it. rotation of the operating mechanism to which it belongs and thus stops the corresponding toothed wheel 137. Each operator mechanism remains locked in the position reached, by its lock 250.

   Due to the stopping of the toothed wheel, while it continues its rotation until the completion of the revolution, the
 EMI58.1
 b "" -4r

  <Desc / Clms Page number 59>

 coupling device 138-123-122 swivels and continues its rotation, with the drivers 138 and 122 inclined, until the completion of the outward travel of the shaft 100. It should be noted that during this whole first phase of the movement, no totalizer disc is driven, because the selection has not yet become effective.



   As the drive shaft 100 stops after its forward stroke, the cam boss 550 (Fig. 44) reaches the roller 552 of the curved lever 554 and rotates the latter which, in turn, rotates. raises the end of lever 562 (Fig. 46) and rotates pin 154. As described with reference to Figs. 6 to 10, the pivoting of the axis 154 imparts to the selection shaft 125 the axial movement, in which the selected totalizer participates, the notched chins 110 'of which are placed in the plane of the corresponding coaches 122. Then begins the return movement of the toothed sectors 574 and 576 and of the control shaft 100.



   In its return rotation, the control shaft 100 does not immediately drive the totalizer discs 110 and the toothed wheels 137. This drive does not start, for each numerical order, until the moment when the driver 138 , meeting the groove 139 of its toothed wheel 137, engages therein and straightens the coupling device. At the same time, the notch 254 of the segment 255 is in front of the roller 253 of the locking device and allows the latch 250 to move back and unlock the entire corresponding operating mechanism.

   From this moment the toothed wheel 137 drives, by the coupling device 138-123-122 the totalizer disc (s) 110 of the same numerical order of the selected totalizer (s) and, by the pinion 242, the sector toothed 592 and the entire operating mechanism, up to the rest position thereof, that is to say until the completion of the return rotation of the control shaft 100. It is understood that, in each numerical order, the totalizer disks 110 accompany the control shaft 100 for as many tenths of a turn as the operating mechanism has been able to make tenths of its outward travel, before being stopped by a

  <Desc / Clms Page number 60>

 key pressed, and this number of tenths is equal to the numerical value of the key pressed.

   Thus, for example, if the digit to be recorded in a given numerical order is "7", the operating mechanism has been stopped by the key "7" pressed, after seven tenths of its travel; Coupling mechanism accompanied toothed wheel 137 for seven tenths of a turn, then it rotated and performed the remaining three tenths without toothed wheel 137, with coaches 138 and 122 tilted. On the return, trainers 138 and 122 remain tilted for the first three tenths of a lap then straighten up when trainer 138 encounters groove 139, and train totalizing discs 110 for seven tenths of a cough, causing them to register the number. 7.

   When the shaft 100 and the operating mechanisms stop, the boss of the cam 550 (Fig. 44) leaves the contact of the roller 552 of the lever 554, and the lug 558, by striking the finger 557 of the lever 554, returns this to its normal position, as do the lever 562 and the pin 154, following which the selection shaft 125 slides with the totalizer (s) which participated in the operation and moves the chinsticks 110 apart 'of their disks 110 of the coaches 122. The machine is thus ready for preparation for the next operation.



   During a zeroing operation of a totalizer, the operation differs only slightly from that which has just been described. The preparatory operation of the control lever 310 causes, through the shaft) 168, the cam 569 and the balance 565, the axis 154 sliding to the right, so that the end of the lever 562 is placed in the part right of the slots 560,561, as shown in FIG. 47.



   As soon as the machine is started up, the boss of the cam 551 raises, by the roller 553, the curved lever 555, and the latter actuates the lever 562 and the axis 154, which makes the selection of the totalizer effective. wants to reset. At this time, the cams 187 and 188 (Fig. 41) rotate, as

  <Desc / Clms Page number 61>

 describes the toothed sectors 574 and 576 and, with them, the operating mechanisms and the control shaft 100. The coupling devices 138-123-122 being normally in the active position, all of the totalizer discs 110 of the selected totalizer accompany the 'shaft 110 until each of them is stopped (by the meeting of tooth 140 of its reading wheel 120 with stop 281,
Fig. 20) in zero position.

   As soon as a disc 110 reaches this position, its driver 122 which continues to rotate with the shaft 100, tilts, causing the bar 123 and the driver 138 to pivot, which thus ceases to drive, its toothed wheel. 137 with the toothed sector
592. Segment 255, which continues to rotate with shaft 300, advances latch 250 which locks the entire operating mechanism in the position reached.



   At the end of the forward stroke of shaft 100, cam 551 releases roller 553, and curved lever 555 is returned to its normal position by lug 559 which, at this moment, hits the finger. 557 of the lever 555. This lowers the lever 562, and the axis 154, by pivoting in the opposite direction, returns the selection shaft 125 to its normal position, by moving the totalizer discs 110 away from their drivers 122. The return rotation of the shaft 100 is therefore done without driving discs 110. During this return rotation, the coaches 122 and 138 straighten up as each of the latter meets the groove 139 of the corresponding toothed wheel 137 which, from that moment, returns the operating mechanism, unlocked by its segment 255, to its rest position.



   Whether it is a recording or zeroing operation, during the forward stroke, toothed sector 574 (Fig.



   41) drives, by its button 578, the connecting rod 590 to the right and, towards the end of the stroke, the latter rotates, in the direction of clockwise, the frame 643 with the bar 642 which pushes back all the forked levers 631 against the hubs of the plates 248, which is necessary for the operation of the indicator which will now dare described.

  <Desc / Clms Page number 62>

 



  Indicator.- The indicator consists essentially of packets of rectangular plates 601 (Figs. 1, 36, 51, 52, 53) bearing on one side the characters or figures used to compose the desired indication. These packs of plates are grouped into two sets, the plates of one of the series bearing their inscription on the operator's side, and those of the other series on the customer's side, so that each complete indication appears. on both sides of the body.



  So that these two indications appear simultaneously, the two packs of plates which, in the two series, must show the same sign or number, are united in pairs by a common command. Thus, the packs of plates indicating the centimes of each of the two indications form a pair, and the same applies to the plates indicating respectively the decimes, the units etc., and also for the two packs of plates bearing the conventional signs which, as the case may be, characterize the genre of the operation in progress or the totalizer involved in it.

   It should be noted that the two packs of plates forming a pair are not leaned against each other; on the contrary, so that the indication on each face of the case is correctly composed, the two packs of plates, for example those of the centimes, which form a pair, are located at the opposite ends of the indicator, so that their digits are the last, on the right, in each indication.



   In the example shown, each series comprises eight packs of plates: (the first on the left) for the conventional signs, and the other seven for the digits from 0 to 9, which makes it possible to dial any amount up to 99999.99 . Each plate 601, except the last of each pack, is extended downwards by a rod 602 and in each pack the rods are laterally offset with respect to one another. The other (Figs. 51 and 53) so as to be arranged in steps. The rods 602 of each pack pass through correspondingly shaped openings of the frame 600 of the indicator and a guide plate 603 supported, above the frame 600, by

  <Desc / Clms Page number 63>

 amounts 604.

   Each plate can occupy an upper position, in which the number it bears is visible behind the window of the indicator, while the lower end of its rod 602 is at the level of the frame 600; and a lower position which it reaches by descending vertically from a height equal to that of the plate 601 to uncover the next plate of the package.



  The first plate of each packet being that which bears the number zero, and the other following numbers in the order on the successive plates, it is understood that it suffices, to compose any amount, to lower , in each. package, as many plates as the amount to be composed contains units in the corresponding numerical order. The last plate of each package should never be lowered; therefore it is fixed and has no stem.



   The raising of the plates 601 lowered during a previous operation and the descent of the plates with a view to composing the amount of the operation in progress, are effected with the aid of an operating member 605 (Fig. 36). in the form of an inverted trough, which extends over the entire width of all the plates and rests, by its top, on a bar 606. This bar is guided vertically by two rods 607 which support it and which slide at the interior of the uprights 604. The trough 605 has side legs 608 which pass, below the plates, between neighboring packages. Each tab 608 carries a drive member such as an elastic roller 609 which fits into the gap between neighboring plate packs.

   The friction between the roller 609 and the edge of the plates 601 is sufficient to cause in the descent, with the rollers 609, those of the plates which are not retained in the upper position.



   The descent of the plates is controlled by the following mechanism: Two pairs of vertical connecting rods 610 (Fig. 36) are ar-

  <Desc / Clms Page number 64>

 Linked, at the top, to the bar 606 and at the bottom, with two levers 611 which can pivot on journals 612 fixed to the supports 613 which are assembled to the plate 101 of the machine. Each lever 611 has a notch 614 in which is engaged a roller 615 fixed on an arm 616 which is wedged on the shaft 192. Between the two arms 616 is wedged on the shaft 192 an elbow lever 618, each arm of which carries a roller 619, 619 'respectively. The rollers 619, 619 'cooperate respectively with carnes 620, 621 wedged on the shaft 200 which makes one revolution per operation; therefore, the lever 618 impresses the shaft 192 with an oscillation during each operation.

   This oscillating motion of shaft 192 is transmitted by arms 616, rollers 615, levers 611 and connecting rods 610 to trough 605 as a downward motion followed by an upward motion.



  The profile of the carnes 620, 621 is such that at the beginning of each operation all the plates are raised and remain in their upper position until, towards the end of the operation, the trough 605 descends in resulting in those plates which have meanwhile been released for this purpose. The plates are released using the following mechanism, identical for each of the numerical orders:
Below the frame 600 and the lower end of the rods 602 when the plates 601 are in the upper position is a series of juxtaposed slats 622 (Figs. 36, 51,52, 53, 54), one for each pair. packets of plates 601.

   Each slat 622 carries a pair of horizontal legs 623 and 624, which come to be placed below the rods of the two packages of plates of the same numerical order and are supported, by their free ends, on angles 625 along the frame 600. Each slat is guided longitudinally by its elongated slots 626 in which pins 627 are engaged and, in the extreme right slot (Fig. 51) a pin 628. At the right end, the lower edge of the slat - that slat 622 is cut into a rack 629.



   When a slat 622 is in its extreme left position, its legs 623 and 624 support the rods 602 of all -

  <Desc / Clms Page number 65>

 indicator plates 601 of the two packs of plates in the corresponding numerical order. These plates, one packet of which is turned towards the operator and the other towards the customer, are therefore all in the upper position and show the zero inscribed on the first plate of each pack.

   The rods 602 of the plates being staggered, as shown in plan in FIG. 53, it suffices to move a slat 622 with its legs 623 and 624 to the right a certain number of "steps" (each of which is equal to the distance by which each rod 602 is offset from the following rod) to allow to as many plates, in each of the two packages that this slat commands, to descend to the lower position and discover the inscription on the first non-lowered plate.



  So for example when, in a given numerical order, the digit to be recorded is "4", the batten 622 corresponding to the same numerical order must be moved to the right by four steps, which will allow the first four plates to be lowered. respectively bearing the numbers 0, 1, 2, 3 and will show the number "4" on the next plate which is not lowered. Each rack 622 is controlled for this purpose from the key mechanism via the operator mechanism of the same numerical order.



  Each operating mechanism, in addition to the components already described, comprises, articulated at 630 to the plate 248 (FIG. 17), a fork-shaped lever 651, the bifurcated end of which cooperates with a lug 633 of a sector. toothed 632 pivoting on the shaft 300. The possibility of pivoting the lever 631 with respect to the plate 248 is limited by the hub 248 'of this plate which hits the middle part of the lever 631, curved so as to bypass the hub. It has already been explained how, during each recording operation, this plate 248 turns clockwise by an angle proportional to the number of units to be recorded in the numerical order at which it belongs, and how it is returned to its resting position at the end of the operation.

   The movements of

  <Desc / Clms Page number 66>

 lever 631 are transmitted by the lug 633 and a connecting rod 634, a curved arm 635 which is integral with a helical wheel 636 and can rotate with the latter on a shaft 637 (Figs. 17 and 51) supported by ears 638 of the frame 600. The helical wheel 636 meshes with a pinion 639 wedged on a small transverse shaft 640 also supported by the frame 600. The shaft 640 also carries a spur gear 641 in mesh with the rack 629 of the batten 622.



  The transmission ratios of all these members are such that the rotation of the plate 248 limited by the depression of a key causes a movement to the right of the slat 622 by a number of "steps" equal to the number carried by the key. key pressed; therefore, as many plates 601 are released, in each of the two packs of a pair, to descend and discover the next plate on which the same number becomes visible. The movements of the transmission components are controlled, by the lever 631 and the lug 633 of the toothed sector 632 as follows:
The amount of a previous transaction indicated by the plates 601 remains visible until the next transaction during which the previous indication disappears to make room for the new indication.

   While at the end of the previous operation, the plate 248 has been returned to its rest position by the means already described, the lug 633 of the sector 632 has been held in place, using the locking device slats 622 described later.



  Therefore, the fork 631 has performed a movement consisting of a rotation around the lug 633 and a translation along the line 630-633. When, at the start of the current operation, the plate 248 advances again in the direction of clockwise, by pulling the forked lever 631, the latter repeats, in the opposite direction, said compound movement, until its curved middle part comes to rest against the hub 248 'of the plate 248.



   If, from this moment, the movement of plate 248 continues, which is the case when the number to be marked is greater than the number marked during the previous operation, the lever

  <Desc / Clms Page number 67>

 631 describes a simple rotation around the axis 300 and moves the pin 633 with the sector 632, the connecting rod 634 and the other transmission members to the position which corresponds to the new number to be marked.



   If the new number is equal to the one previously marked, the lever 631 stops as it rests against the hub 248 'of the plate 248.



   Finally, if the new number is smaller than the previous one, the lever 631 stops with the plate 248, without coming into contact with the hub 248 'of the latter.¯ So that the indicator can mark the new number, it is therefore necessary that the lever 631 is pushed back against the hub of the plate 248 by bringing the sector 632 with its lug 633 to the position which corresponds to the new number. This is done with the aid of a bar 642 which extends over the entire width of the key compartment and constitutes one side of a rigid frame, the other sides of which are formed by a yoke 643 which can pivot. on the axis 350 The yoke 643 is connected by an arm 644 (Fig. 27) to a fork 645 which carries a roller 646 cooperating with a cam 647 wedged on the camshaft 200.

   The profile of this cam is such that at the moment when sectors 240 or 245 (depending on whether it is a recording or zeroing operation) have completed their outward movement and are momentarily stopped, the cam 647 gives the fork 645 a rapid movement to the left which results, at the bar 642, in an oscillation in the direction of clockwise. During this oscillation, the bar 642 hits the back of the curved part of all the levers 631 which have remained away from the hub of the corresponding plates 248, and pushes them towards them. The levers 631 which undergo this movement, drive the pins 633 and the corresponding sectors 632 and place them in the position which corresponds to the number to be marked by each of them.

   The corresponding indicator plates 601 being thus released by the slats -622-controlled from the lug 633, the amount of the operation

  <Desc / Clms Page number 68>

 in progress will appear on the indicator as the trough 605 is lowered by the means described. It should be noted that the indicator indicates not only the amount of a recording operation, but also that of a reset, because the indicator is controlled by the intervention of the plates. 248, whether these are moved by the toothed sectors 240 (recording) or by the toothed sectors 245 (zeroing).



   In order to neutralize the possible play of the joints, it is necessary to ensure the correct alignment of the slats 622 immediately after their displacement, before the released plates 601 have started their downward movement. Then, until the end of the current operation and until the start of the next operation, the slats 622 must be locked against any untimely displacement. For this purpose an alignment device is provided controlled from the camshaft 200. A lever 648, angled at right angles and pivoting on the shaft 192 (Figs. 51,52), carries at the end of one of the its arms a roller 649 cooperating with a cam 650 wedged on the shaft 200. A spring, not shown, tends to apply the roller against the surface of the cam 650.

   The other arm of the lever
648 is connected, by a connecting rod 651, to one of the ends of a flail
652 suspended, pivotally to one of the axes 640 (the seventh from the right, in the example shown) of the slat control mechanism 622. At its other end, the flail 652 is connected, by its buttonhole 653 and a button 654, to the aligner itself.



   This is made up of two levers 655, 655 '(Figs. 51 and 55) pivoting on pivot screws 656 screwed into fixed bars 657 which flank, on either side, the slats 622 and carry the brooches
627 serving as guides for the slats 622. At their free end, the levers 655, 655 'are connected by a transverse knife 658 which can engage in the hollows of a toothing 659 made on the underside of the slats 622, and of which the step corresponds to the steps of the movement of the slats.

   When the machine is at rest, the cam 650

  <Desc / Clms Page number 69>

 presents to the roller 649 a circular surface of large radius (Fig. 52) which holds the elbow lever 648 in a position such that the right-hand end of the flail 652 is pulled down and the knife 658 is lifted and engaged between the teeth 659 of the slats 622 which are thereby correctly aligned and locked against displacement. At the start of the operation, the cam 650 presents the roller 649 with its reduced radius surface and, under the action of its spring, the elbow lever 648 pivots, lifting the connecting rod 651 and the flail 652, the other end of which descends in removing the knife 658 from between the teeth 659. At this point the movement of the slats 622 begins in preparation for the inscription of the new post on the indicator.

   As soon as the slats have been moved, the cam 650 pushes the lever 648 again and locks the slats 622, aligning them with precision, in their new position until the end of the operation, while the plates 601 go down by showing the amount to which the transaction in progress relates.



   It has been said that at the end of the operation, the pins 633 of the sectors 632 are held against any movement by the aligner device. It will therefore be understood that, while the slats 622 are blocked by the knife 658, the transmission members, among which are the connecting rods 634 and which connect these slats each to a lug 633, are also immobilized, so that the lugs 633 and the toothed sectors 632 are effectively locked until the time when the slats 622 have to be moved in order to prepare the inscription to the indicator.



   The operation of the indicator, as described heretofore, relates to the seven pairs of packets of plates 601 which carry digits to compose the amount of transactions. The indicator, however, has an eighth pair of packs of plates (from the right) which do not indicate numbers but signs characterizing the individual totalizers participating in the operation or designating the type of operation. .



  This pair of plate packs is therefore not

  <Desc / Clms Page number 70>

 not controlled by means of the plates 248 which accompany the toothed sectors 240 or 245, but directly from the selector lever 290, which as explained, is placed, prior to each operation, in a position which determines the selection one of the individual totalizers, or of the day totalizer alone (with a view to setting it to zero), or even operation without any totalizer (so-called "change" operation).



   Next to the selector lever 290 (Fig. 55) there is, idle on the central shaft 500, a toothed sector 632 with its lug
633, and a forked lever 631, identical to those already described. However, this lever 631 is articulated, at 630 to the body of the selection lever 290, and can be applied against the hub 690 of this same lever 290. Because all the elements of the indicator remain blocked, since the end of the previous operation, until the indication of the operation in progress appears, the connections described could prevent the movement, prior to any operation, of the selection lever 290, in particular when this movement must be done from the bottom up.

   In order not to hinder such a movement of the lever 290, the rigid connecting rod 634 connecting the lug 633 to the curved arm
635 is replaced by an extendable connecting rod, made of two parts
634 and 634 ', articulated respectively to the lug 633 and to the arm 635.



   Each of the parts has a button, respectively 671 and 671 ', engaged in a buttonhole, respectively 672' and 672 of the other part of the. connecting rod, so that the connecting rod 634-634 'can extend: when the lever 631 being applied against the hub 690 of the selector lever 290, the latter is moved from bottom to top, driving the lever 631 and the toothed sector 632, the part 634 of the extendable connecting rod moves from right to left, driven by the bit 533.



   The button 671 'of the right part 634' of the extendable connecting rod is caught in the forked end of an elbow lever 673 which can pivot on the axis 192. The other end of the lever 673 forms a spout 674 which is located near the cam 620 fixed on the

 bre 200. At the start of each operation, when all the indicator plates are raised as explained, as a result of the rotation of the cams 620 and 621, a pin 675 fixed to the side of the cam 620, hits the nozzle 674 and tilt lever 675 counterclockwise.

   As a result, the right part 634 'of the extendable connecting rod, previously lengthened by the operation of the selection lever 290, is pushed to the left, so that the buttons 671 and 671' reach the bottom of the buttonholes 672 and 672 'and the connecting rod is reduced to its minimum length; moreover, it moves entirely to the left, by causing the lever 631 and the toothed sector 632 to pivot, the lug 633 of which advances into the slot of the lever 631. Then, while the control shaft is stopped 100, when the bar 642 pushes back, as described, all the levers 631, it also acts on the lever 631 of the mechanism in question and brings it back against the hub 690 of the selection lever, thus placing the toothed sector 632 with its button 633 in the position which corresponds to the sign that the first pair of plates must show.

   This sign will appear, along with the transaction upright, as the trough 605's is lowered as described.



  Printing - The printing mechanism hereinafter referred to as "printing", intended to print the amount to which each operation relates, as well as other useful indications; both on a ticket issued to the customer and on a control strip which remains in the machine, is controlled from the toothed sectors 632 which have already been mentioned in connection with the control of the indicator.



   The printing press, housed in the left part of the machine, between the partition 104 and a support plate 700 (Fig. 56) supplies the following printed documents:
1) The ticket, intended to be delivered to the customer, and on which are printed the name of the firm, the date, the order number of the ticket, and the amount recorded or canceled; when the recorded amount consists of several items, the word "total" and the

  <Desc / Clms Page number 72>

 the result of the addition of the items, known as the "receipt total", are also printed. Beside the amount is printed a sign characterizing the individual totalizer which carried out the recording.



  Likewise, a conventional sign, for example "R1", placed transversely to the line, next to the upright, indicates a zeroing operation.



   2) The serial number, the amount of the transaction and the characteristic sign of the totalizer are also printed on a control strip which remains inside the machine, in a locked compartment.



   3) The cash register described makes it possible to use, instead of receipts, forms filled in by the seller. These cards are obliterated by the machine which prints on them the date, the serial number and the amount which is, at the same time, recorded by the appropriate totalizer (s).



   The characters used for printing the transaction amounts are located at the periphery of printing wheels 702 (Fig. 57) each having twenty teeth which carry two series of numbers from 0 to 9, and which can rotate freely on one. pin 701 attached to bulkhead 104. Each wheel 702 meshes with an intermediate pinion 703 which is idle on pin 704, and is in turn engaged with a special gear 705 (Figs. 56,57). The wheels 705 are each wedged on the end of a tubular shaft 706, these shafts being fitted one over the other and supported by a shaft 707 supported by the partition 102 and by a bearing 708 rotating with the shaft in the support plate 700. The bearing 708 also carries a gear 705, the last one on the left.

   The support plate 700 is rigidly assembled to the left-hand partition 104 by spacers 709 and the axes 701 and 704 of the toothed wheels 702 and 703. The tubes 706 and the shaft 707 whose axial displacement is prevented by a flange 711 attached to the plate 700, receive rotational movements from the plate 248 and the toothed sectors-.652 of the previously described operating mechanisms (Fig. 17).

  <Desc / Clms Page number 73>

 



  For this purpose, each tubular shaft 706, as well as the shaft 707 carries, near its right end, a toothed wheel 710 in engagement with one of said toothed sectors 632. It will be remembered that there is such a sector for each numerical order of the amount that the machine can register, and that during the operation each sector is brought, by the plate 248 and the forked lever 631, in an angular position which corresponds to the number of units to be registered in the numerical order considered. To each toothed sector 632 corresponds a toothed wheel 710 and at the other end of the shaft 707 or of the tube 706, a toothed wheel 705 whose amplitude of rotation is thus determined by the figure to be recorded and printed.

   It should be noted that, like the sectors 632, the toothed wheels 705 pass, in the course of successive operations, from one active position directly to the next, without passing through an intermediate rest position.



   The printing on the paper which passes, with the ink ribbon, under the type wheels 702, is obtained by the living force of three hammers 720, 721 and 722 (Figs. 60, 61) which strike the paper at the bottom. right of the characters to be printed. Behind the wheels 705 and at their lower level is fixed a transverse bar 712 which rigidly connects the plate 700 to the partition 104 and bears the invariable text of the stamp to be reproduced on all tickets, namely the text at the bottom of the ticket and the header of it.



  The separation of the issued ticket is made between these two parts of the stamp, so that the formula at the foot of the ticket is on the issued ticket, while the header is printed at the top of the ticket which will be issued in the next operation . Behind the stamp 712 is the date stamp whose axis 713 (Figs. 59 and 60) is supported by the partition 104 and the plate 700. On this axis is wedged the first of the character discs 714, which is that of tens of days; the other discs, the characters of which make up the date, are carried by the right ends of the tubular pins 715, one

  <Desc / Clms Page number 74>

 on the other and on the axis 713. The opposite ends of the axes 715 and 713 are extended beyond the left wall of the machine (Fig. 59) and carry buttons 716 which allow the date to be dialed by hand. wanted.

   The correct alignment of the date discs is ensured by pressure springs 717 (Fig. 60) fitted at one end in a support 718 fixed to the partition 104.



   The three hammers 720, 721 and 722, which are used for printing the ticket, are located below a horizontal plate 719 which separates them from the compartment of the type wheels described, but has openings allowing the hammers to hit on the characters to be printed. The hammers, which each have the shape of a prismatic body lined with elastic material, are attached to levers pivoting about a pin 725 attached to the partition 104 (Figs. 60, 61). The date hammer, 720, is carried by two levers 730 braced at the free end by a control rod 726; a similar rod 727 braces the ends of the two levers 731 which carry the stamping hammer 721, and a third control rod 728 braces the levers 732 of the hammer 722 which prints the amount of the operation.

   All these levers are furthermore interlocked, on the common axis 725, by intermediate rings 734. The hammer 722 comprises a small independent part 723 intended to print the ticket number and capable of being made inactive, this which is necessary in the case of a recording at several stations: these do not receive a number, only the total amount receives one.



   The hammers are controlled by means of the control rods 726, 727 and 728 which are extended through the partition 104 towards the interior of the machine and are hinged there to the vertical control rods 740, 741 and 742, respectively (Fig. 64). At their upper end, the three connecting rods each have an eyelet which surrounds the control shaft 500 which, engaged by the electric motor, makes one revolution per operation. On the ar-

  <Desc / Clms Page number 75>

 bre 500 is wedged a cam 736 (Figs. 64 and 66) which is used to control hammers 720, 721 and 722. A second caine 737, also wedged on the shaft 500, controls another hammer 724 intended to perform printing on the control strip, as described below.



   Each of the three connecting rods 740, 741 and 742. is biased downwards by a spring 743 attached on the other hand to a fixed support 745 common to the three springs. The connecting rod 742 which controls the hammer 722 printing the upright, carries near its top a pin 746 which passes through slots 747 made in the upper part of the connecting rods 740 and 741, and on which is fixed a roller 748 cooperating with the cam 736. This cam is circular in shape with a notch 749 which presents itself in front of the roller 748 at the instant when printing is to take place. At this instant, the roller falls into the notch 749 under the effect of the spring 743 which pulls the connecting rod 742 downwards, and the two connecting rods 740 and 741, previously retained by the pin 746, descend at the same time.

   The levers 730, 731 and 732 therefore pivot rapidly on their axis 725 and the three hammers 720, 721 and 722 quickly strike the character wheels through the interposed paper and ink ribbon, after which the cam 736 returns all these parts to their rest position.



   While printing the items which are to be added to a receipt, the small partial hammer 723 should remain inactive; likewise, hammers 720 and 721 must remain stationary, because the serial number of the ticket, the company stamp and the date must only be printed once, together with the total of the ticket. The immobilization of hammers 723, 720 and 721 is controlled from the control lever 310 when the latter is placed in its 3rd. bottom position, called "ticket with addition !!, It has been explained that, during the movement of the lever 310, the shaft 168 which extends between the partitions 103 and 104 (Figs. 6 and 7) receives a rotational movement, the amplitude of which depends on that of the displacement

  <Desc / Clms Page number 76>

 cementing of lever 510.

   Near the partition 104, therefore in the vicinity of the printing mechanism, the shaft 168 carries a grooved cam 750 (Figs. 7 and 65) in which is engaged a pin 751 which carries a connecting rod 752. When the control lever is in its 3rd. In this position, the connecting rod 752, which is normally in its lower position, is pulled upward by the cam 750 and the spindle 751.



   At its lower end, the connecting rod 752 is articulated to a lever
753 which can pivot around pivot 754 attached to frame 104. When connecting rod 752 is lifted, it lifts lever 753 and brings finger 755 to the free end thereof below a pin 756 attached. to the connecting rod 740 which controls the hammer 720. This pin passes through the connecting rod 740 and engages in the upper part of an elongated hole in the connecting rod 741 which controls the hammer 721.



   When, at the time of printing, the connecting rods 740 and 741 are released by the notch 749 of the cam 736, they are prevented from descending by the pin 756 which strikes the finger 755; alone, the connecting rod 742 descends and actuates the hammer 722. To avoid printing the ticket number during this operation, the partial hammer 723 is made retractable, being supported by a rod 729 and guided vertically in the body of the ticket. hammer 722 (Fig. 57). Near its end near the hammer 722, the lever 732 thereof has a slot 757 (Fig. 57) in which a pin 758 can slide which is carried by an arm 733. This has an eyelet through which the pin 725 passes. hammers so that the arm 733 can move slightly approximately horizontally.

   The bifurcated end of the arm 733 grips a transverse bar 760 integral with the rod 729 carrying the retractable hammer 723, while at the opposite end the arm 733 has a notch 761 in the form of an arc of a circle, in which a lug 762 of a circuit breaker lever is engaged
763 (Figs. 64 and 68). This lever can pivot on the tube 706 ', which is the outside of the coaxial tubes 706, and its upper arm carries a lug 764, engaged in a profiled slot 765 of the lever 753.



  When connecting rod 752 lifts lever 753, lever-circuit breaker 763

  <Desc / Clms Page number 77>

 rotates counterclockwise, its pin 762 pulls the arm 733 to the right (in Fig. 57), so that its pin 758, following the inclination of the slot 757, descends and lower arm 733 with bar 760 and hammer
723 of an amount sufficient to render it ineffective while the large hammer 722 strikes for printing the post.



   As has been said, in addition to the cam 736, the shaft
500 carries a cam 737 which controls the printing of amounts and serial numbers on a control strip, using a hammer 724 (Figs. 64 and 65). This hammer is integral with a lever 766 capable of pivoting on the axis 754 fixed to the partition 104 that an arm of the lever 766 passes through a suitable opening (Fig. 65). The lever 766, which a strong spring 768 tends to swing counterclockwise, is articulated to a connecting rod 769 embracing, by a buttonhole made at its opposite end, the shaft 500 on which the connecting rod is thus guided. The connecting rod 769 carries a roller 770 which cooperates with the cam 737, the shape of which is identical to that of the cam 736.

   It is therefore understood that, when the notch of the cam 737 presents itself in front of the roller 770, the latter engages therein, and allows the spring 768 to suddenly pull the lever 766 to the left (in FIG. 64). which causes the hammer 724 to strike the necessary blow for printing with the aid of the second series of characters carried by the printing wheels 702.



   During a zeroing operation, it is necessary, in addition to the amount to which this operation relates, to print a distinctive sign, for example "R1" to indicate that it is not a registration operation. For this purpose, one uses a connecting rod 773 articulated, at its lower end, to a short lever 774 pivoting on the axis
754 and guided, near its upper end, by the shaft 168, a circular groove of which is engaged in an axial slot of the connecting rod 773. The widened upper end of the connecting rod 773 has a transverse profiled slot in which a lug is engaged 772

  <Desc / Clms Page number 78>

 fixed on the right side (Fig. 65) of the cam 750 fixed on the shaft 168.

   When this is, at the same time as the control lever 310, in one of its extreme positions, which is the case when the day totalizer J or one of the individual totalizers A, B, D or E must be reset, the lug 772 lowers the connecting rod 773 and, with it, a curved bar 775 (Fig. 69) which is integral with it and passes through an opening in the partition 104; the curved bar 775 is articulated, by a pivot 776, to the first wheel 703 'of the intermediate wheels 703, which engages not with a character wheel 705 (like the other wheels 703), but with a special wheel 705' which bears, on only one of its teeth, the character designating the zeroing operation.

   When the connecting rod 773 is lowered, this movement is transformed, at the wheel 705 ', into a rotation which brings the character of this one opposite the hammer 722, so that the distinctive sign of zeroing will be printed next to it. the amount of this transaction.



   Above the character wheels 702 (Fig. 60) is the paper roll 781 forming the control strip. The paper unwinds from a reel 780 fitted on a fixed axle 782 and passes over two guide rollers 783, which hold it in a horizontal position between the hammer 724 and the wheels 702; from there the paper is directed by further rollers 784 to take-up reel 785 on which the printed web is stored at 786. Between the neighboring guide rollers 783 and 784 is, above the paper, a prism 787 glass reader, allowing the last printed amount to be read; for this purpose, the paper of the tape is translucent and the prism is total reflection, its hypothenuse serving as a reading mirror.

   The spool which receives the printed roll 786 consists of two half-cylinders assembled by a bolt 788 and a spring 789 which presses the half-cylinders against each other. A two-pin wrench 790 (Fig. 63) forming a fork is inserted between the two halves of the coil 785. This wrench also takes

  <Desc / Clms Page number 79>

 in a slot made in the end of the shaft of the reel 791 which can turn in the partition 104, going beyond it towards the interior of the machine (Fig. 65). The key 790 therefore makes the axis 791 integral with the spool 785 and allows the latter to be turned, with the roller 786, by hand. To take out the printed roll, simply remove the 790 key, which allows the two halves of the spool to come together and remove the roll.

   The compartment containing the rolls 781 and 786 is isolated from the other parts of the printing mechanism by sheets 792 and 793 and is accessible from the outside, by a door, not shown.



   The end of the axis 791 which penetrates towards the interior of the machine through the partition 104 (Figs. 63, 64,65, 67) carries a ratchet mechanism which ensures the automatic advancement of the control strip. This mechanism comprises a cup 794 wedged on the axis 791 and an idler plate 795 with two cutouts in the form of half-segments, and a cover 796 (Figs. 64 and 67) extended by an arm 797, rigidly mounted on the plate 795. In the cutouts of the plate are housed two rollers 798 subjected to the pressure of two small springs 799 housed in holes of the plate 795, so that each roller 798 is wedged between the plate and the inner surface of the plate. the cup 794. when the plate 795 turns in the direction of the arrow (Fig. 67) it therefore drives the cup 794 and the shaft 791.

   On the outside of the bowl is a fixed block 800 with a cutout in the form of an inclined plane in which is housed a roller 801 acting on the bowl as a retaining pawl when the latter rotates in the opposite direction to the arrow. (Fig. 67). A small control arm 802 (Fig. 64), which rotates on the axis 791, is articulated at 803 to a connecting rod 804, the bifurcated end of which embraces the shaft 500 on which it is thus guided.



  The connecting rod 804 carries a roller 805 engaged in a groove of a plate 806 wedged on the shaft 500. The shape of the groove is such that, during the revolution of the shaft 500, the connecting rod 804 is first. pulled to the right (Fig. 64) then, after printing, pulled back

  <Desc / Clms Page number 80>

 in its initial position, and the arm 802 participates in these movements.



   A spring 807 hooked to the end of the arm 797 pulls the latter towards the pin 803 which connects the arm 802 to the connecting rod 804, so that the arm 797 with the cover 796 and the plate 795 participate in the movements of the arm 802 , under the action of the spring 807 on the outward journey, and under the thrust of the spindle 803 on the return. During this return, the plate 795 drives the axis 791 of the reel 786 and advances the control strip by one step.



   The uniform advancement of the web at each printing is ensured by the following adjustment mechanism: Two arms 811 wedged on an axis 810 (Figs. 60, 62, 630 carry a groping roller 812 which normally rests on the pressure roller. .pier 786. The axis 810 which crosses the partition 104 door, on the other side thereof, (Figs.



   64, 65) an arm 813 to which is fixed a pin 814 which comes to be placed in the path of the arm 797. While the latter pivots under the action of the spring 807, it meets the pin 814 and then stops that the small arm 802 still continues its rotation.



   The amplitude of the pivotal movement of the arm 797 (and with it, of the spool 785 of the roller 786) is therefore regulated by the position of the spindle 814, i.e. by the diameter of the roller 786, and the profile of arm 797 is such that as the diameter of the roller
786 increases, the amplitude of the pivoting of the arm 797 decreases to advance the paper by an invariable amount with each operation.



   A safety device prevents the operation of the machine when the paper in the control strip has run out. In front of the feed roller 781 is a retainer
816, the arms 817 of which are wedged on an axis 818 carried by the partition 104 which it passes through. A torsion spring 819 (Fig. 63) which surrounds the axle 818 and is fixed to this axle and to the partition 104, tends to rotate the axle and thus presses the retaining roll 816 against the paper roll. 781. At the end of the axis 818 is wedged

  <Desc / Clms Page number 81>

 an arm 820 (Figs. 63, 65) articulated on the other hand to a connecting rod 821 connected in turn to an angled rod 822 which, supported by small brackets 823 near the machine plate, extends over the entire length of it.

   Near the other side of the machine, the bent rod 822 is hinged to a vertical link 824 (Figs. 33, 35), the upper end of which carries a lug 825 engaged in a slot 826 at the lower end of the machine. locking arc 497. The control tape paper is wound onto a longitudinally halved take-up reel, the two halves being held together by the paper itself. When this is almost exhausted, the two halves of the spool 780 separate and fall out. As a result, the retaining roller 816 rotates counterclockwise, passing below the axis 782 of the spool 780.

   Under the action of its spring 819, the axis 818 participates in its movement, and its arm 820 lifts the connecting rod 821 and, via the rod 822, the connecting rod 824 and the lug 825, the arc lock 497 is also raised and locks the trigger button 440, thereby preventing the machine from being started.



   The web of paper supplying the tickets constitutes, inside the machine, a large roll 828 carried by a spool 827 (Figs. 60 and 62) fixed to the partition 104; the roller is retained laterally by a disc 829 fixed by a knurled nut 830.



  The paper coming from the roller 828, is guided by the rollers 831 and 852 and then passes, between the table 719 and a sheet 833 which protects it against contact with the ink ribbon 834, towards a drive mechanism. The latter comprises a cylinder 835 and two pressure rollers 836 (Figs. 60, 61, 63). The driving cylinder 835 is supported on one side by a bearing 837 fixed to a sheet 838 which supports the table 719, and on the other side in the partition 104 beyond which the axis of the cylinder carries a pinion 839. This pinion (Figs.



  61,64) is meshed with an idle toothed wheel 840 on a fixed axis -

  <Desc / Clms Page number 82>

 841. The hub of the wheel 840 constitutes a cup in which is housed a unidirectional drive device with rollers, similar to that which controls the drive of the control strip. Its roller carrier plate 842 (Fig. 65) is integral with a cover terminating in an arm 843 (Fig. 64). A lever 844 pivoting on the pin 841 is articulated at 845 to a connecting rod 846.

   As the operation of the drive device is identical to that of the control strip, it will suffice to say that the toothed wheel 840 is only driven, in a clockwise direction, when the lever 844 is pivoted, in the same direction, on the axis 841, which takes place under the control of the plate 806 wedged on the shaft 500, and of its groove 848 in which is engaged a roller 849 of an arm 850, which pivots on the shaft. 'shaft 150 and is articulated to connecting rod 846. With each movement of toothed wheel 840 which meshes with pinion 839, drive cylinder 835 rapidly rotates at an angle such that the paper advances the length of a ticket. .



   The pressure rollers 836 are freely mounted, above the cylinder 835, on eccentric bulges 851 of a rod 852 journaled in the partition 104 and in a fixed support 853 (Figs. 60, 61, 62, 63). The angular adjustment of the rod 852 therefore makes it possible to modify, if necessary, the pressure of the rollers 836 on the paper; a lever 854 is used for this purpose, which is wedged on the rod 852 and ends in a button 855. One of the faces of the support 853, which comes above the paper, is bevelled and serrated ( Fig. 63), so that the printed ticket can be easily torn off, pushed out of the machine, by the drive device 836-835.



   It will be understood that during the printing of several amounts intended to be added together on the same ticket, the paper must advance, at each printing, only one space and not the entire length of the ticket. This modification in the paper feed is controlled from the control lever 310 which, in order to

  <Desc / Clms Page number 83>

 of the operation in question, is placed in its 3rd. position known as: "ticket with addition". This position of the lever 310 corresponds to a position of the shaft 168 such that the cam 750 wedged on this shaft keeps the connecting rod 752 (Figs. 64,65) raised. The lever 753 that the connecting rod controls, is therefore raised to the right of its axis 754, and lowered to the left.

   At the left end, lever 753 carries a pin 857 which normally lies out of the path of paper advancing arm 843 ', but comes into its path when it is. lowered. In this case, the arm 843 is stopped, by the pin 857, after a low amplitude rotation and remains pressed against this pin, under the action of its spring 858, until the return of the lever 844 whose amplitude of oscillation remains invariable, and the pivot pin 845 returns the arm 843 to its normal position. The slight oscillation thus effected by the arm 843 is sufficient to impart to the receipt paper, via the toothed wheel 840, the pinion 839 and the driving cylinder 835, an advance movement which corresponds to a line spacing.

   Then, after printing the total of the ticket, the latter receives a normal advancement movement, so that its total length is equal to that of an ordinary ticket plus the length occupied by the printing of the added items.



   The zeroing operations result in the issuance of an ordinary ticket; only a distinctive sign, printed next to the amount, just like on the control strip, indicates that it is a zeroing operation.



   On the axis 701 of the printing character wheels 702, to the right of these (Fig. 58) are similar wheels 860 which are used to print the serial number of each operation, both on the receipt. than on the control strip. These wheels 860, the twenty teeth of which carry two series of characters from 0 to 9, are controlled by a counter mechanism so as to add, for each printing, a unit to the number previously printed. Cha-

  <Desc / Clms Page number 84>

 that wheel 860 is flanked by a ratchet wheel 861, each wheel comprising two series of ten teeth separated by diametrically opposed notches 862.

   On the axis 701 of the wheels 702 can pivot a frame 836, the two lateral sides of which carry an axis 864 on which are mounted drive claws 865 which cooperate with the ratchet wheels 861. The claws 865 are angularly offset. 'relative to each other (Fig. 57) by a value slightly greater than the height of one tooth of the wheel 861, so that normally only the claw cooperating with the wheel 860 of the units can act on it to make it turn the length of a tooth and thus add a unit to the number to be printed. When this wheel, after having made a U-turn, arrives at position "9", the next wheel 860, the tens wheel, must advance by one.



    At this moment, the claw 865 of the units is in front of a notch 862 and engages in this one, thus allowing the axis 864 to pivot a little under the action of a spring 866 and to bring the next claw 86b, (that of the tens), engaged with the corresponding wheel 861. On the next oscillating movement of frame 863 which operates wheels 861, two of these, (those for units and tens) will each be advanced one unit, which causes wheel 860 to move units to position " 9 "to position" 9 ". When the second wheel 861 has also reached the "9" position, its notch 862 will allow the third claw 865 to intervene to drive the wheel 860 hundreds, and so on, up to the fourth and last wheel 860.

   The correct angular position of the wheels 860 is ensured by pawls 867 pivoting on a small fixed axis 868 and engaging, under the action of leaf springs 869, fixed on the cross member 712, between the teeth of the wheels 861.



   The wheels 861 integral with the character wheels 860 are controlled via the frame 863. The pin 864 which carries the claws 865 and is mounted between the two lateral sides of the frame, is connected to a connecting rod 870 (Figs. 59, 64) folded so as to turn the toothed wheels 840 and articulated at the opposite end;

  <Desc / Clms Page number 85>

 at 871, to a guide arm 872 pivoting on the hub of part 844 of the ticket paper drive mechanism. A hook 873 (Figs. 64, 65) freely mounted on the journal 845 of the part 844 can catch on the extension of the articulation axis 871 between the connecting rod 870 and the arm 872; it is held in this position by a spring 874 stretched between itself and the part 844.



  Each oscillation of the part 844 itself controlled by the connecting rod 846, the lever 850 and the cam 806, is thus transmitted, by the connecting rod 870, to the frame 863 which performs a complete oscillation and adds, by means of one or more several claws 865, one unit with the number composed by the wheels 860. However, during the printing of several items on a single ticket, these items are not assigned a serial number, such a number being allocated only in total of the ticket. The wheels 860 must therefore not be actuated while printing the items to be added. It has been explained that, during their printing, the stroke of the arm 843 is limited to a small amplitude by the pin 857 of the lever 753 (Fig. 64). The arm 843 carries a lug 875 located in front of the hook 873.

   The adjacent face of the hook has a profile such that when the arm 843 is stopped while the lever 844 continues to move, the reaction of the hook 875 lifts the hook 873 and disconnects it from the guide arm 872, against the tension of the spring 874. The wheels 861 are therefore not actuated and the number dialed by the wheels 860 remains unchanged.



  When the described parts return to their normal position, which takes place when the ticket total is printed, the hook 873 again hooks up to the lug 875, under the traction of the spring 874.



   When character wheels 702 and 860 are brought into position for printing the amount and serial number, they must be aligned and held in place for the duration of the printing. The alignment is ensured by the horizontal bar 878 of a frame 879 (Figs. 60 70) which can oscillate on the fixed axis 880 supported by the partition 104 and the support plate 700, so as to engage

  <Desc / Clms Page number 86>

 manage the bar 878 between the teeth of the wheels 702 and 860. To the frame 879 is fixed a rod 881 which passes through a hole in the partition 104 and is articulated to a connecting rod 882 which connects it to a balance 883 pivoting on the axis 884 of a driving cylinder 885 of the ink ribbon.



  The upper arm of the balance 883 carries a roller 886 which cooperates with a cam 887 wedged on the shaft 500. The depth and the wedging angle of this cam are such that the balance pivots in the opposite direction to that of the needles. 'a watch when the wheels 702 and 860 have already dialed the numbers to be printed, but before the actual printing. Bar 878 is then drawn between the teeth of wheels 702 and 860 and locks these in the correct alignment until printing is complete, after which cam 887 allows balance 883 to return to its idle position. rest, under the action of a not shown return spring. The wheels 702 and 860 are thus released for the purpose of composing the digits to be printed during the following operation.



   The balance 883 simultaneously controls the advancement of the ink ribbon 834. This endless ribbon bypasses the '702 and 860 imprint wheels, as well as their control wheels 703 and 750 (Figs. 57,60) and can travel guided by rollers 888, 889 and 890. The ribbon 834 also passes over an ink roller 891 surrounded by a layer of felt soaked in ink, then over the drive roller 885, and finally over a tensioning roller 892. The latter can rotate between two flanges 893 subjected to the action of springs 394 attached on the other hand to a spacer 895 connecting the support plate 700 to the partition 104.

   On the end of the axle 884 which passes through the partition 104 towards the interior of the machine is wedged a ratchet wheel 896 (Fig. 70) which can be actuated by a pawl 897 articulated to the lower arm of the balance 883 and is subjected to the pressure of a spring 898. At each printing operation, as the balance swings to align and lock the character wheels, the pawl 897 turns the ratchet wheel 896 by one tooth of output.

  <Desc / Clms Page number 87>

 such as: The cylinder 885 drives the ink ribbon 834 of a corresponding length.



   As has been said, the machine is also suitable for the obliteration, at each operation, of a form filled in advance, for example by the seller. In this case, there is no need to issue tickets. When the machine is to operate in this way, the roll 828 of receipt paper is removed beforehand, and at each operation the card is slid into the slot between the table 719 and the paper guard plate 833 (Figs. 60, 62) in view of the printing of the transaction amount, the order number and the date.



  The hammer 721 bearing the stamp of the company must be made inactive, as well as the pressure rollers 836, in order to facilitate the passage of the card. For this purpose, the handle 854 (Figs. 61, 62) is used, the button 855 of which can be moved axially. The rod 899 of the lever can engage in one of the two holes "T" or "F" of the support plate 700, where it is held by the pressure of a spring 900. When the rod 899 is engaged in the hole "T", which corresponds to the described operation of the machine, with issue of tickets, the eccentricity of the bulges 851 of the shaft 852 is directed downwards (Fig. 60), and the rollers 836 are pressed against the drive cylinder 835. In addition, the tail of the lever 854 is engaged in a cutout 901 of the table 719 and obstructs the slot between this table and the sheet 833.

   On the other hand, when the handle is brought to position "F", for operation with plugs, the tail of the handle is withdrawn from the cutout 901 and clears the path of the plugs; at the same time, the rollers 836 are raised so as to no longer press on the cylinders 835 and to release, on their side, the slot through which the cards pass.



   Below the hammer 721 (Fig. 60) which needs to be immobilized, there is a lever 902 which can pivot on a fixed axis 903. The upper end of the lever 902 forms a hook which can be seated. 'hook to a rod 904 integral with the hammer 721. In the body

  <Desc / Clms Page number 88>

 of the lever 902 is made a curved slot 905 in which is engaged a pin 906 carried by the end of a curved lever 907 whose opposite end is wedged on a pin 908 journalled between the partition 104 and the sheet 838 which supports the table 719. On the end of the axis 908 which passes through the sheet 838 is fixed a small lever 909 whose opposite end can obstruct the cutout 901 of the table 719.

   Normally, lever 909 is lowered by the tail of lever 854 (Fig. 62), against the action of a spring, not shown, which tends to lift the free end of lever 909.



  Pin 906 of lever 907 is then at the top of slot 905 (Fig.



  60) and thus keeps the hooked lever 902 away from the rod 904 of the hammer 721. But if the lever 854 is placed in the "F" position, its tail releases the lever 909 which is raised under the action of its spring. , and rotates its axis 908 with the lever 907, the pin 906 of which draws the lever 902 to the right, so as to hook the latter to the rod 904 of the hammer 721 and to immobilize the latter.



   It should be understood that the invention extends to each of the various mechanisms described above, considered separately, as well as to the combination of these mechanisms, resulting from their co-operation, in a cash register constructed and operating. nant as it has been exposed.
