T0 (LM whom t may concern.'

Be it known that l, THOMAS CARROLL, a citizen of the United States, residing at Dayton, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in Cash-Registers, of which l declare the following to be a full,` clear, and exact description.

This invention relates to cash registers and has for a main object to provide an improved mechanism of the class described which will include a registering device and printing devices.

A* second object is to provide an improved construction for preventing an operation of the counter when desired, as for example in connection with certain kinds of special transactions.

An improved printing mechanism including multiple type is provided which is normally at an intermediate position and therefore is arranged to take only a minimum movement to bring any desired type to printing position.

Another object is to provide an improved and automatic reversing device for an.ink ribbon.

It may be desired at times to use the machine without the printing attachmentf'tnd I provide means brought into operation automatically by the removal of the record holding means for preventing the operation of the printing mechanism.

The provision of the removable record holding means also has the function of providing for a segregated analysis of transactions. By the provision of the detachable means each clerk may be provided with an individual record strip holding means, and upon operating the machine he may insert his particular record holding means in the machine and receive upon the same a printed record of the transaction handled by him. In this way each clerk would have a printed record made by the machine of his findividual sales. The machine may also be dsed to provide a separate record strip holding means for different cashiers when on duty, and as long as a cashier is on duty his record holding means may be permitted to remain attached to the machine, but on leaving the post the cashier would'then detach hisrecord holding means and the new cashier going on duty would substitute for the same his own record holding means. In this manner the proprietor of an establishment employing a machine of this type will be enabled to ascertain just how muehof the days business was handled by the different clerks or cashiers in his employ.

Viith these and incidental objects in view, the lnvention consi-sts in certain novel features of construction and combination of parts, the essential elements of which are set forth in appended claims and a preferred form of embodiment of which is hereinafter specifically described with reference to the drawings which accompany and form part of this specification.

Of said drawings: Figure 1 is a transverse section of a machine of a well known type to which I have shown my invention as applied. Fig. 2 is a rear elevation of the same. F ig. 3 is an elevation of lone end of the machine showing the printing mechanism. Fig. 4 is a transverse section near the left hand end lof the machine showing the controlling devices for the printing mechanism. Fig. 5 is a section o n another line showing the throw out mechanism for the counter and Athe special keysand connections controlling the same. F ig. '5 is Ia detail of a key arrester for thesp'eci'al keys. Fig. 6 is a detail showing the special printer and operating devices therefor.

My invention is adapted to be used with many types of cash registers and I have shown it as adapted'for and applied to a prior invention for which Letters Patent of the United States numbered 879,081 and 977,509 did issue on February 11th, 1908, and December 6th, 191,0, respectively, as well as other applications showing substantive improvement on the same. The machine is of the so called key operated type. The keys are arranged to differentially operate the register segments which are mounted Ion a piv- .oted frame. A cQmmon key member such as a key coupler is provided, the operation of which serves to rock the segment carrying clinations but are inclined in different di rections so that some keys will move the plate in one direction and some keys in a reverse direction thereby rendering necessary only a maximum movement of the type carrier of five steps instead of a maximum of nine steps as is the case in most prior machines.

The record holding devices are arranged to be removed easily from the machine and means are provided for preventing the striking of the type hammers when such removal has taken place.

I provide a reciprocating device for operating the ink ribbon feeding mechanism carrying two oppositely directed pawls with means for bringing them alternately into operation the said means being controlled by the ribbon itself.

lescribed in general terms the machine comprises a series of keys 10 here shown as levers pivoted on the main rod 11 and having a vertical portion 12 at the rear end thereof, this vertical portion having differently graduated slots 13. The cut away portions 13 are adapted to abut and move a rod 14 carried by arms 15 and the frame including the rod and arms serves to differentially move the registering segments 16. The usual tablet indicators 17 are provided having their stems resting on the eX- treme rear ends of the keys. Each of the keys 10 has a slot 18 in which a rod 19 of a key coupler 20 is adapted to move and therel'iy couple together any depressed keys. lieferring now to Fig. 5 it will be seen that l provide a cam 21 having a depressionwhich normally engages an anti-friction roller 22 carried by a pivoted rod 23, this mechanism being duplicated at the two ends of the machine. The arms 23 are pivoted on the main rod 11 and serve with the rod 24 to forma rigid frame. This rod 24 carries the registering segments and it will be evil:lo

dent that when any key is depressed the cams 21 Will serve to raise the arms 23 and thereby move the rod 24 to carry the segment racks 16 into engagement With the pinions of the counter wheels this engagel ment. being caused before the cut away portions 13 of the keys reach the rod 14. When the keys reach the lower end of the stroke 'Y nroiecting arm 26 of the key coupler abuts against a cam device carried by rod 24 so that the coupler is then shifted laterally a sufficient distance to carry the cams 2l from under the rollers 22. Onthe instant that the key starts to return the arms 23 are allowed to drop back to normal position thereby carrying the segments 16 out of gear with the pinions 25 and this occurs before the segments have started their reverse oscillation due to the return of the keys. It Will be seen that this provides a one Way connection between the segments and the counter wheels.

So much of the machine as has been de-Y scribed is shown inthe prior patents and I will now pass to a description of my present improvements and will first describe the so called throw out mechanism for the counter.

The machine is designed to take care of different classes of transactions and some of these such as Charge sales Money paid out and f Money received on account should obviously not be included in the register but a printed record of the same is desired. I therefore provide means controlled by special keys representing the desired transactions for preventing the operation of the counter and to this end means are provided for coupling the arms 23 to a counter carrying frame so that they will move together. Tn Fig. 5 I have shown the counter frame indicated by numeral 31. This is pivoted loosely on the rod 11. Mount- .ed on the counter frame 31 is a bell crank 100 lever 32 pivoted at 33 and having an antifriction roller 34 at one end and notches 35 and 36 near the other end. The notch 35 is normally surrounding a pin 37 carried by the counte` frame. The notch 36 is nor- 105 mally over a flange 37 on the arm 23. Special keys 38 are provided for the desired special transactions and these keys are also journaled en rod 11. Their rearwardly tending portions 39 have cam projections 40 110 adapted when the keys are depressed to engage the anti-friction roller 34 and elevate the same therebyrocking the bell crank 32 around its pivot 33 and serving to engage the notch 36 with the flange 37'* and to dis- 115 engage the'- pin on the counter frame from the notch 35. It will be seen that this connects the counter frame 31 to the arms 23 andA therefore that when the arms 23 are rocked 'through the elevation of the key 120 coupler the frame will be rocked as well so that the segments 16 vvill not'engagc the counter wheel pinions 25 and thereby opera.- tion of the register is prevented. To compel 'a complete depression of the special keys 'I 125 the key coupler. When any special key 38 J 1s depressed the rearward extension 39 there- I 'of engages the flange 41 rocking the' same rearwardly and depressing the hook 44 in front of the projection 45. When the key 38 is completely depressedthe extension 39 passes .above the flange 41' and the same,

i time this moves forwardly' under the key 38 as a spring 47 connects the lever 42 toa pin on the main frame of the machine. A 'projection 49 is provided on the cam 21 and i this projectionserves when the keys arey completely depressed to-engagea projection 50 on thelever 42 and restore the same to normal position thereby releasing the special keys.v

The special keys 38 do not support indi- Y Acators as do the value keys as it is not deated cams on projections 56 of .the specialA wardly.

sired to expose the indicators until the value indicators are also elevated while it will be remembered that the special keys are depressed before the value keys. I provide therefore levers 51 .one for each of the special keys which are also journaled on the main rod 11 and which serve to support special indicators 52. These indicators are arranged to be slightly elevated through connections set from the special keys so as to couple them to the key coupler which then provides for the furthervelevation of the said indicators. An arm 53 is provided journaled on the pinA 54 on the counter frame .and normally pressed forward as shown by a Spring. This arm 53 carries on the lower end thereof a pin 55 which is adaptedvto be engaged by differently gradukeys so that when any one of the keys 38 is depressed the arm 53 will be rocked rear- Such rearward rocking serves to bring a fiange 57 on the said arm over the forward end of the desired one of the levers 51. When the value keys are thereafter depressed the counter vframe is rocked as it is at this time coupled rocking serves to slightly depress the arm 53 so that its flange 57 abuts and moves the desired lever 51 and elevates the rear. end of the same enough to couple it to the key 'coupler. The vfurther operation of the value key serves to elevate the special indicator as well asthe desired. value indicator.

To prevent a depression of more than one lspecial key at an operation I provide a key arrester shown in Fig. 5a. It will be seen in Fig. 5 thatthe special keys have depending projections 61 and these are adapted to engage the.spool shaped part 62 carried loosely on a rod 63. The depressed portion of the spool is only wide enough to allow one special key projection 61 to be moved to the arms 23 and this.

therein. If the center key 38 is depressed no movement of the :spool 62 takes place while if either 0f the two outside Special keys are depressed the spool is moved in one direction or the other .but no two special keys can be depressed at'tl`e same time.

The printing mechanism is best shown in Figs. 2, 3 and 4. I provide plates 71 one for each bank of value keys at the extreme rear of the machine. These plates 71 have cut therein slots one for each key of the Abank and the slots have differently graduated inclined portions 72. In the normal position these-slots are directly over the keys 10 and it will be clear that the depression of the forward end of any value key will raise the rearward end thereof causing it to pass up the corresponding vslot 72 and thereby cause a lateral movement of ,the plate 71, these plates being supported by a pin and "slot connection 73 to allow such lateral movement. Each `plate is connected to a link 74 and these links 74 are connected to bell crank levers 75 journaled on arod 76. Connected to the levers 75 are vertical arms 77 having segment racks 7 8 as integral parts thereof, the arms being bent as shown in Fig. 2. As shown in Fig. 3 the racks 78- mesh with segments 79 which carry on the front ends thereof separate type .bars 80`- These type bars are separately carried by pin and slot connections oni the segments 79 each type barhaving thereon two numerals. The movement of the type bars to cause an impression on the record material is accomplished through the agency of hammers 81 these hammers being mounted on a shaft 82 and having a slot 83 in which a pin 84 of a lever 85 is adapted to ride. The lever85 is journaled on a pin, 86 and has a projection 87 with a notch 88 in which a lever 89 shown in Fig. 3 but better shown inFig. 4 normally rests. When the lever 89 is rocked t0 carry it away from the notch -88 the leverv 85 may rotate under spring tension thereby causing the pins 84 to ride down in the ,slots 83 and thereby throwing the hammers friction roller 95 carried by an arm 96 rigidly mounted on the shaft supporting the, key coupler and which is indicated -by numeral 98. YVhen the coupler is raised it will be clear that the roller 95 will ride up-I wardly in the slot 94 and serve to rock the bell crank lever 92 around its pivot 93 thereby tensioning spring 91. As shown in Fig. 4 spring 91 passes through a hole in a flange 99 on the lever 85 and is provided with' a screw 100 the head of which will not pass through the hole in the said flange. It will be seen that in the normal position 1li' lthe i parts shown in Fig. 4 the spring 91 is under no tension but when the lever 92 is rocked as before described the spring will be tensioned and will bring the head of the screw 100 against a (lange 99, movement of the flange being prevented by the lever 89. The arm 96 is provided witha projection 101 adapted to engage as the coupler reaches the end of its upward stroke with a pin 102 on the lever 89. As this lever 89 is journalecl on the pin 103 it will be seen that at the end of the key coupler stroke the` leverwill be raised away from the notch 8 8 of the arm 87 and the spring 91 will then throw the type hammers 81 quickly forward to take an impression. When the keys return to normal position the lever 92 is reversely rocked and the lever 85 thenereturns to the position shown in Fig. 4 thereby carrying back the type hammers 81 through an arm 104 carrying a rack 105 engaging a pinion 106 on shaft 82. This arm 104 i's moved forward by the hammer stroke and is retamed by key coupler rod 19.

I have beforestated that each type cnrrier has two different type thereon but this causes no confusion of impression as the platen roller is of so small a radius as to curve away from the type not set for operation.

The record' holding mechanism is provided to be easily removed from the machine and in such case it is not desired that the printing hammers should strike the type. The record mechanism includes a holding roller 111 and a winding and feeding roller 112 as well as the platen roller 113. These rollers are mounted on pins carried by a plate 111 best shown in Fig. 4. The said plate has a cut away portion 115 near the bottom thereof which is adapted to surround a rod 1!6. A head 117 on the rod 116 prevents lateral movement of the plate 114. It will be clear that the plate 114 may be Considered as pivoted on the rod 116 and means are provided For retaining the top of the plate in its desired position. This means in.- cludes a latch *118 adapted to be laterally moved manually when desired in whichcase the yplate lli may be rocked around rod 116 through a projection 119 at the top of the plate. lt will be seen that the plate and the rollers carried thereby are a separable structurc which may be easily removed by simply throwing the latch 118. To prevent* the printing laannners from striking when the ref-ord holding means is withdraw from normal position l provide an arm 121 normally "pressed bv a spring 122 to a position in the path ol' the end 122i of lever 85. This arm 121 is however normally held against the tension ot' spring 122 and in the position shown in Fig. 4 by a link 126 the forward end ohr-lush' is adapted to contact with the projection" il@ op the plate 114. The link use a link 131 connected to the 4the rollers is 126 is provided with a slot surrounding a pin 127 to allow it a rearward and forward motion. 1t will be seen that when E ttch y11j-l is tripped and plate 114 rocked :forwardly the project-ion 119 thereof will be moved 70 is made the elevatIon of the coupler will 75 still raise arm 96 thereby rocking lever 92 and tensioning spring 91 bug the upward movement of lever will evi ently be prevented by arm 121 so that no movement of the type hammers can take place.

To provide for feeding the record previously mentioned lever 92. This link 131 is connected by a pin 132 to a lever 133 carrying a pawl 131 which is spring pressed the teeth of the ratchet 135 on the wm ing roller 112. The lever 133 and'pawl 134 are carried by thje frame of the machine but ratchet 135 is carried by plate 111 and will so strip I to engage 35 of course be removed when.the said plate is withdrawn. A retaining pawl 136 is provided to prevent backward movement of ratchet 135 and this is carried by a pin on plate 114i It will be seen from this mechanism that when the coupler is elevated arm 96 will be rocked thereby rockin lever 92 and drawing arm 131 rearwar ly.v This rearward motion will cause the actuating pawl 134 to move backward over the teeth of ratchet 135 and on the reverse movement 100 are shown in Fig. 4. Two rollers 1-11 and 142 are provided which serve alternately as feeding rollers for the ribbon 143. Each of provided with a ratchet 144 or, 115 having oppositely Journaled on the pin 146 is a vertical plate 147 having slots 148 in which pins 149 mounted on the main frame are adapted to move. It will be seen that this plate 147 can have no movement except a s tion around its pivot 146, the extent of oscillation depending on the length of the slots 148. Two notches 151 and 152 are provided on the upper end of the plate 147 and The ink ribbon and its :feeding mechanism arranged teeth.

ight oscillaan arm 153 is arranged to be drawn by a 120 spring 151 connecting the arm to the main frame into one or the other of the said notches thereby serving to hold the plate 147 in either of its two extreme positions. This plate 1-17 has mounted thereon two pins 161 125 167, the pawl 166 being adapted to engage 130 ratchet 145 for feeding roller 142 and the pawl 167 being adapted to engage ratchet 144 for feeding roller 141. Connected to the plate 165 by a pin 171 is a link 172 which is also connected by a pin 173 to the bell crank lever 92.

It will be remembered that lever 92 is oscillated at each operation of the machine by the raising and lowering of the coupler and it will be clear that as plate 165 is connected by link 172 to the lever 92 that the plate 165 will be reciprocated at each operation of the machine and thereby cause a feed in one direction or the other of the ink ribbon. When the ribbon is completely unwound from one of the spools as is shown in Fig. 4 a succeeding operation of the machine will cause the pawl which is at the time operative, here shown as pawl 166 to engage the tooth of ratchet 145 and en. deavor to operate the same. The pawls 166 and 167 are provided with extensions 181 and 182 and these extensions are connected by a long'spring 183. 'When the parts are inthe position of Fig. 4 and an operation 0f the machine is made the pawl 166 will as stated engage ratchet 145 but will be unableto rotate the same as the ribbon is completely unwound from the spool 141. The pawl 166 will thereby rock around its pivot pin and throw the carrying plate 147 to its other position this being possible through the yielding of spring 154 which will cause the arm 153 to then engage notch 152 and hold the plate 147 in its new position with pawl 167 adapted to engage the teeth of ratchet 144. It will be seen that this mech anism provides an automatic reversing device for the ink ribbon.

To print characters on the record strip indicating the special key if one has been depressed I provide mechanism shown in Fig. 6. The special keys 38 have edges 191 adapted to engage a rod 192 carried by arm 193 the arms being journaledk on rod 63. The arms 193 are rigidly connected to a vertical bar 194 and this is connected through a link 195 to a bell crank 196 having at the forward end thereof a plurality of type carriers 197. It will be understood that the edges 191 of the special keys 38 are so shaped as to differentially rock the arms 193 and thereby bring the desired type 197 to the printing point. It will be seen that although there are only three special keys in the machine as shown I have provided four type 197. The type' which is normally at prlnting position is adapted to cause an arbitrary character such as a dash to be printed thereby indicating that a cash sale has been made. When however one of the special keys is depressed the corresponding type is brought toprinting position and a letter indicating transaction is printed on the strip.

It is desired to provide means for alining the type carriers while they are being printed from and to this end I provide the segments 79 with a series of notches 201 as shown in Fig. 3. A plurality of pawls 202 carried rigidly by a shaft 203 serve to engage the notches 201 and to exactly place the type. These pawls are adapted to be rocked into and away from the notches by a plate 204 (see Fig. 5) also rigidly carried..75 by shaft 203. This plate 204 has a cam slot- 205 cut therein and a pin 206 movable with the coupler rides in the said slot. It will be clear that as the said coupler is elevated pin 206 will finally' reach the cam portion of slot 205 and rock the plate 204 rearwardly. This will evidently serve to depress V`the pawls 202 into the proper notches 201 and lock the type until an impression has been taken therefrom.

provide means for locking the printer operating plates 71 when no key in the-corresponding bank is depressed I provide bent arms 211 these arms being shown in Figs. 1 and 2. These arms 211 are fastened to the plates 71 and bent around and under the keys. The forward ends of the arms are bifurcated and in the bifurcations levers 212 are adapted to engage, thereby lockingv the plates 71 against lateral movement. The levers 212 have at the forward ends thereof lateral rods 213 extending under the keys of the corresponding bank. It will be seen that while the bent arms 211 are normally locked against lateral movement by the levers 212 that a depression of any key in the bank will depress the pin 213 thereby elevating the rear end of a lever 212 enough to allow lateral movement of the arm 211 and consequently to allow" the printing de- 105 vices to be set.

It is desired that the mechanism should be locked while the counter is being returned to zero and mechanism for accomplishing this result is shown in Fig. 5. The counter shaft is indicated in this figure by the numeral 221 and it has mounted thereon a disk 222 cut away as indicated at 223. The lever 42 previously referred to has connected at its upper end a bar 224 which has a slot 225 surrounding the shaft 221 a'ndt serving to guide the arm. Pin 226 is mounted in the forward end of the arm 224 and normally rests in the cut away portion 223 of the disk 222. It will be clear that when disk 222 is rotated by turning the shaft 221 to reset the counter that pin 226 will be forced V forwardly thereby rocking the lever 42 and depressing the projection 44 in the path of projection 45 on cam 21. This evidently locks the mechanism as cam 21 is carried ri idly with the key coupler. It will be evident that such rocking of lever 42 will move rearwardly the flange 41 at the bottom of said lever thereby serving to 13e thereby returningr 55 normal position in .which they are locked release a special key if such key has been depressed. 'lhe operation of the machine will be clear from the foregoing descrip` tion but it may be briel'ly described as follows. To register an amount the keys 10 corresponding to the amount areI depressed and then allowed to resume their normal position. l'Vhen the keys are depressed the coupler 20 rises with the rear ends of the 19 keys thereby rotating the cam 21 and raising arms 23 and rod 24 carrying the segments 16 which actuate the counter wheels into mesh with the said wheels. The further depression of the keys serves to raise the cut away portion 13 thereof to engage the rod 14 and to thereby rock the segments 16 to add the desired amount on the counter. iVhen the keys reach their lowest position the coupler is moved laterally and the cam 20 21 thereby carried from under the rollers lVhen the keys 10 start to return the arms 23 immediately drop allowing the segment 16 to be withdrawn from the counter wheels and the segments are thereafter re- 25 turned to normal position out of mesh with the said wheels.

'lhe depression of any value key 10 depresses the rod 213 thereby elevating the rear end of the lever 212 corresponding to 'the bank in which a key has been depressed.

of keys may be moved laterally as the reiiir4 up the slot 72. This plate 71 serves to set the correspoinling printing segments 79 through the link 74, lever 75 and bent arm 77. As the cvnpler moves upward the arm 96 carried therewith rocks lever 92 and thereby tension spring 91. As the coupler reaches its ul'ipermost position projection end of the key passes 35 lateral motion Aof the 101 rocks the lever Sl thereby releasing the S5 when the spring vafesllie said lever and carried ther-(ninth 91 immediately cle` causes the pin 84 to throw the printing hammer S1 against a type carrier to force said carrier to impressing position. The forward.movement of llever serves t0 nieve forward the arm 1071 through the pinion 106 mounted on shaft S2. lVhen the keys return to normal position the rod 19 of the key coupler strikes or arm 104 moving the saine rearwardly the printing hammers to by theilever H9.

When a special transaction is to be en tered in the'n'rachine the operation is in large part the saine as whent.he cash sale is registered. In this hitter case however a special key is first depressed and the'cam 39 carried thereby rocks levelli 32- aronnd its pivot 33 and thereby serves to connect the arms mi the counter frame 31. When the arms ..3\are\roeked around their pivots 11 the counter frame will be also moved so that the segments 16 remain out of mesh With the register wheel pinions 9.5 and no amount is added on the counter'. It will of course be remembered that this operation of rocking' the counter frame does not take place until the value keys are depressed. 'The' depression of the special key serves to the machine until the key has reached its lowermost position through the movement of lever 42 which is cammed by the rear1 end of the special key. When the special key isl depressed the depending projection 56 thereof rocks the arm 53 to' bring a flange 57 over the desired indicator lever 51. When the value key isdepressed and the' counter frame rocked flange 57 slightly raises the rear end of lever 51 to couple the lsame to the coupler so that when the value keys are thereafter' operated the special indicator will 4be raised. The depression of the special key serves to position a printing device through the mechanism shown in Fig. 6. At each Voscillation of lever 92 the ink ribbon feed pawls are reciprocated to slightly feed the record material.

The record holder may be removed by tripping latch 118 when the arm 121 im mediately springs forward and serves to prevent the operation of the printing' hammers. A while the printing takes place by the pawls 202 controlled .from camming arms 201.

It will be seen that the machine is normally adapted to both print and.register the amount indicated on the value keys but it will of course be understood that the print ing devices or the registering device may be dispensed \vitli.3.l/Vhen a special transaction is to be entered the register is automatically prevented from operation. T operation of the printing mechanism may be dispensed with by'inerely tripping the latch thereby permitting the record holding plate tolfemove slightly forward.

While the form of mechanism here shown and described is admirably adapted to fulfil the objects primarily stated, it is to be understood that it is not intended to con line the invention t'o thel one form of embodi @ment herein disclosed` for it 1s susceptible of the forward edge embodiment in various forms all comin within the scope of the claims which follow.
