GUSTAVE O. DEGENER, OF NEVI YORK, N. Y., ASSIGNOR TO UNDERWOOD COMPUTING MACHINE COMPANY, OF NEW YORK, N. Y., CORPORATION OF NEW YORK.

COMBINEDTYPE-WRITING AND COMPUTING MACHINE.

Application filed May 27, 1913.

To all whom it may concern:

Be it known that I, GUSTAVE O. DEGENER, a citizen of the United States, residing in New York city, in the county of Ne v York and State of New York, have invented certain new and useful Improvements in Combined Type-l v riting and Computing Machines, of which the following is a specification.

This invention relates to a new and improved means for automatically controlling the state of one or more computing heads as to adding, subtracting, etc., and is shown in connection with a machine of the combined typewriting and computing type, such as that illustrated in an application of 'VValter lVright, No. d85,0 l6, filed March 22, 1909, now Patent No. 1,24%,397.

In prior automatic mechanisms for controlling the character of computation carried on by the computing heads, either the typewriter carriage or the computing mechanism has been burdened with this additional mechanism, which added to the com plexity of the mechanism and slowed up the action thereof.

It is, therefore, an object of this invention to relieve the typewriter carriage and the computing mechanism of such extra burden by providing a separate device entirely distinct from the typewriter carriage and the computing mechanism, for automatically controlling the character of action of the computing heads.

In carrying out this object, use is made of the tabulating mechanism of the typewriter, so that every time a tabulating key is actuated to bring the typewriter carriage to a new computing zone or column, a controller, shown in the form of a disk, will be given a step movement to bring into play one or more positioning buttons according to the number of computing heads. These buttons are set to shift cooperating linkages greater or less amounts according to their previous positions and according to. the computing states desired. The linkages shift gearing to change the drive as to its direc tion or activity for both the master wheel shaft and the assisting tens-carrying shaft of the corresponding computing heads.

The controller disk is provided with a power of its own and with an escapement therefor actuated by a bar universal to the tabnlating keys, so that when any "tabulat Specification of Letters Patent.

ing key is actuated, the disk will be driven a step by its own power to bring into play a new set of position-determining buttons. The controller disk may be returned manually at the end of each line of writing, so as to reenergize its motive means and so as to bring it back to its initial starting point.

In order to obviate the possibility of the operative forgetting to reenergize the controller motive means and to return the controller disk to its starting point, a lock may be provided, which, at the end of a written line, will come into play to preventthe actuation of the controller and also to prevent the actuation of the tabulatiiig keys. This lock may be adjusted to any of a plurality of positions corresponding to the terminal of the extent of controlling action desired.

In case of an error, or for any other rea son, the automatic mechanism may be op- 75" eratively disconnected and the state of the computing heads controlled manually. For this purpose, the shifter operated upon by the positioning buttons is made composite, so that the train of connection between the 8[. controller and the computing heads can be interrupted at this point and the state of the computing heads determined by the shifting of manual levers.

Other features and advantages will hereinafter appear.

Referring'more particularly to the separate parts of this invention as embodied in the form shown in the drawings, 1 indicates numeral keys and 2 character keys which ar mounted on key-levers 3, so as to depress th same and thus rock bell cranks 4 to swing type-bars 5 up rearwardly against the front side of a platen 6 mounted on a traveling carriage 7. The carrier-get? has a traveling movement under the control of an escapement indicated in general at 8, which in- .cludes a rack bar 9 pivotally mounted, by

means of arms 10, on the carriage 7, and engaging a pinion 11 fixed to an escapement wheel 12. The escapement wheel 12 is con trolled in its movement by fixed and movable dogs 13, which in turn are actuated when any one of the type keys is actuated, by means of a universal frame 14, which is engaged by a heel 15 on each of the typebars 5 as the latter swing upwardly to strike the platen 6.

In addition to this step-by-step movement,

the carriage 7 may be given a jump or tabulating movement. For this purpose,

there are provided tabulating keys 16, mounted on key-levers 17, which are pivoted intermediate their ends, and support at their rear ends plunger stops 18. When a tabulating key 16 is depressed, it raises the associated plunger stop 18'to bring the same into the path of a tabulating stop 19 adjustably mounted on a rack 20 carried by the carriage 7.

When any one of the plunger stops 18 is raised it must release the carriage 7 from its escapement mechanism, indicated at 8. For this purpose, there is provided a lever 21 universal to all of the plunger stops 18 and engaging shoulders 22 provided thereon. This lever 21 when rocked, will draw on a link 23 to rock a lever 24 carrying at its forward end a roller 25 engaging under the rack 9, so that when any one of the tab-- ulating keys 16 is actuated, it will raise the rack 9 out of engagement with the pinion 11, permitting the carriage 7 to travel under the traction of a spring barrel indicated When any one of the numeral keys 1 is actuated, in addition to printing the number by means of the type-bars 5 swinging up to strike the work-sheet on the carriage 7, it also, as will be seen by reference to Fig. 2, pulls on a hook 27 to rock a bell crank 28, the latter drawing on a link 29 to rock a lever 30. The lever 30 carries at one end, a plunger 31 arranged in apposition to one of a series of index pins 32 suitably mounted on an index or valuating wheel 33. Thus when a numeral key 1 is actuated, by virtue of the connected linkage, it will force the associated plunger 31 against the apposite pin 32, setting it from a projecting position on one side of the valuating wheel 33 to a projecting position on the far side of the valuating wheel There is one of these linkages and plungers for each of the numeral keys 1, and they are each arranged in apposition to one of the pins 32.

The plungers 31 are located in apposition to the pins 32 distant amounts corresponding to their particular numeral keys; from a'four-tooth detent wheel 34. This detent wheel 34 normally engages one of the pins 32 which has been previously set up to its position projecting on the far side ofthe wheel 33. The detent wheel 34 looks the valuating wheel 33 against rotation by engagement withthis pin, and is in turn locked by an escapement wheel 35 connected there to by a shaft 36. This escapement wheel 35 normally engages one of a pair of detent dogs 37 and 38 provided on a rock shaft 39. -VVhen a numeral key is actuated, this shaft 39 is first rotated in one direction to permit a movement of one of the teeth of the escapement wheel 35 from engagement with one of the dogs, 37, to engagement with the other of the dogs, 38. Then when the numeral key is returned to its normal raised position, the shaft 39 is rocked in the opposite direction to permit the tooth in engagement with the dog 38 to slip by and the next tooth on the detent 35 will then come into engagement with the first dog, 37, permitting a quarter rotation of the detent wheel 34. This is all caused by the tendency of the valuating wheel 33 to rotate, as will be hereinafter described, which rotation tends to return the detent wheel 34 by reason of the fact that the set pin on the valuating wheel 33 tends to escape by the detent wheel 34.

To rock the shaft 39 at the actuation of any of the numeral keys 1, all of the links 29 extend through slots 40 in a collar-"plate 41, which is mounted for sliding movement against the tension of a spring42. When one of the links 29 is drawn on by the ac tuation of its associated numeral key 1,then' the tail end of the corresponding lever 30 will engagethe collar plate 41, to force the spring 42.

same rearwardly against the tension of the The collar plate 41 cooperates with a second collar plate 43 spaced therefrom to rock a lever 44 resting therebetween, at one end. The opposite end of the lever 44 is connected by a link 45, to an arm 46 on the rock shaft 39.

Thus it will be seen that when a numeral key 1 is depressed to set a pin 32 through the aid of the plunger 31, then the shaft 39 will be rocked in one direction, and when the numeral key 1 is returned, the shaft will be rocked in the opposite direction permitting a quarter of a revolution of the detent wheel 34, so that the pin in engagement therewith will escape by the same and a newly set pin will come into engagement therewith and enable the relocking of the valuating wheel 33. The extent of movement of the valuating wheel 33 depends upon the particular numeral key actuated. That is to say, if the 2 key were actuated, the valuating wheel would move a distance corresponding to the distance of the second pin removed from the pin engaging the locking detent wheel 34.

The valuating wheel 33 may be normally under a tendency to rotate in any suitable manner, as by being provided with a shaft 47, having a gear 48 meshing with'a gear 49 on a shaft 50. The shaft 50 may also be provided with a bevel gear 51 (Fig. 1) engaged by a bevel gear 52 on a shaft 53, which in turn may be driven from a motor 54 through the intermediary of meshing bevel gears 55 and 56 mounted, respectively, on the motor shaft and the shaft 53. A slip clutch may be provided in this gearing, so that when the valuating wheel 33 is locked against movement, the motor may continue to rotate without damage to the mechanism.

The purpose of this rotation of the valuating wheel 33 is to enable the running-up of numbers digit by digit into the computing wheels of one or more computing heads, of which two are shown at 57 and 58. For this purpose, when the valuating wheel 33 is permitted to rotate and the bevel gear 51 is likewise rotated, this movement will be communicated, by means of a bevel gear 59 meshing with the bevel gear 51, to a shaft 60, which in turn transmits it through a pair of intermeshing bevel gears 1 and 62, to a vertical shaft 63. This latter shaft is arranged to drive the master-wheel shafts, of which one is indicated at 64 in Fig. 5. Th refore, each master-wheel shaft is proaided at its outer end with a bevel gear, indicated respectively in connection with the computing heads 57 and 58, at 65 and 66.

Meshing with the bevel gear 65, there is provided a pair of bevel gears 67 and 68 loosely mounted on the shaft 63. Likewise meshing with the bevel gear 66, there is provided a pair of loosely-mounted bevel gears 69 and 70 loose on the shaft 63. Between the pairs of bevel gears 67, 68 and 69, 70, there are provided shiftable clutches 71 and 72, which are capable of occupying any one of three positions corresponding to the rotation of the gears 65 and 66 in one direction or the other, or to a non-rotation of these gears. That is to say, each of the clutches 71 and 72 is provided on its top and bottom with teeth arranged to engage corresponding teeth on the inwardly-facing sides of the paired bevel gears.

It will thus be seen that when one of the clutches 71 or 72 occupies a position connecting one of the paired bevel gears to the shaft 63, the associated master-wheel shaft 64 will be driven in one direction, and when inaposition connecting the other paired bevel gear to the shaft 63, the master-wheel shaft 64 will be driven in the opposite direction. It will be further seen that when the clutch occupies an intermediate position in which neither of the paired bevel gears is connected to the shaft 63, then the associated master-wheel shaft 64 will remain dormant or silent. The master-wheel shaft 64 in each case is provided with a master-wheel indicated at 73, which engages internallyformed teeth 74 on a computing wheel 75. This computing wheel 75 is also provided with external teeth 76 meshing with a gear 77 carried by a dial wheel 78, which is adapted to exhibit the numbers shown up thereon through a sight opening 79 in a computing head casing 80.

The master wheel 73 may be moved step by step through the several computing wheels of both the computing heads to cor respond to the writing of the different digits on the work-sheet located on the typewriter carriage, by means of a lever 191, which may be intermittently connected to the carriage through the intermediary of a latch 192, which engages the different tappets or stops 19 carried by the carriage in a manner shown and described in an application of Valter Wright, No. 574,813, filed August 1, 1910, now Patent 1,244,398.

hen one of the dial wheels and its associated con'iputing wheel has made a complete revolution, that is, when the number exhibited passes from 9 to 0, it is necessary to carry one to the computing wheel of next higher denomination. F or this purpose, there is provided a tens-carrying mechanism, indicated in general at 81, which depends for its action on the rotation and direction of rotation of a rubber roller 82, which is driven from a shaft 83 by interconnecting gearing indicated in general at 84. There is a shaft 83 for each of the computing heads, and it is provided, in this case, on its outer end with a bevel gear, in dicated, in the case of the computing heads 57 and 58, at 85 and 86. The bevel gears merals and 91.

85 and 86 similar to the bevel gears for the master-wheel shafts, mesh with paired bevel gears loosely mounted on a shaft 87. These bevel gears are indicated, in the case of the gear 85, by the numerals 88 and 89, and in the case of the bevel gear 86, by the nu- Clutches 92 and 93 are provided between the pairs of gears to connect one or the other of the paired gears in driving relation with the shaft 87. The shaft 87 is also driven from the motor 54 through the intermediary of a shaft 94, con nected by a pair of bevel gears 95 and 96 at one end to the shaft 87, and by a pair of bevel gears 97 and 98 to the shaft 63 at the other end.

To shift the clutches for the master-wheel shaft and the tens-carrying shaft of each computing head, there is provided a composite shifting lever, indicated in the case of the computing head 57, at 99, and in the case of the computing head 58, at 100. These shifting levers are identical and only one will be described. The composite shifting lever consists of a main lever 101, pivoted at 102, and provided with a pin 103 engaging in a groove in the master-wheel clutch 71 or 72. Pivotally mounted on a pin 104 provided on the main lever 101, there is pro vided a supplementary lever 105, which has a movement relative to the main lever 101, limited by a pair of fingers 106 and 107 engaging opposite sides of the pivot 102. This supplementary lever 105 is provided with a pin 108, which engages in a circumferential groove provided in one of the tens-carrying clutches 92 or 93. The lost motion between the main lever 101 and the supplementary lever 105 is provided, so as to permit the settling of the. teeth in the different clutch faces. This lost motion is taken up by a spring 109.

It will thus be composite levers seen that when one of the is shifted, the associated clutches will be shifted to concomitantly change the drive of the master-wheel shaft and the assisting tens-carrying shaft, so that they will always rotate in corresponding directions either to add or subtract, or they will not rotate at all in the case where it is desired to have the associated computing heads silent.

Of course, these composite levers might be shifted directly manually. In this case, however, each of the main levers is provided with an eye 110, with which engage links 111 and 112 for the computing heads 57 and 58, respectively. The links 111 and 112 are connected, respectively, (Fig. 4) to separate bell cranks 113 and 114, pivotally. mounted on a stub shaft 115, so that they may be rocked by these'bell cranks. The bell cranks are in turn rocked by links 116 and 117, which are drawn on by levers 118 and 119, to which they are connected. These levers are provided with hand- grips 120 and 121, to enable them to be manually manipulated, if desired, one of the hand-grips being bent over to permit more ready access to the other hand-grip.

The levers 118 and 119 are pivot-ally mounted intermediate their ends on a stub shaft 122, so that they may be rocked by a pair of links 123 and 124, which are con nected thereto at their lower ends. The links 123 and 124 may in turn be drawn on by composite shifters 125 and 126, separately pivoted on a stub shaft 127. Each of the composite shifters is provided with a centralizing element 128 and 129, respectively, which in the case of the latter faces upwardly, and in the case of the former faces downwardly, to engage position-determining buttons 130 provided on opposite sides of a rotatable controller disk 131. Each centralizing element 128 and 129 may be formed by providing a pair of flanges 132 and 133 spaced apart from each other and provided with parallel reaches 134 and 135 (Fig. 8),to form a channel therebetween, in which one of the position-determining buttons 130 can pass to fix the location of the shifter 125 for any particular position of the disk 131. The flanges 132 and 133 both flare outwardly from opposite sides of the parallel reaches 134 and 135, so as to form guideways forcing the shifter to move to such a position that the cooperating position-determining button 130 may enter the channel formed between the parallel reaches. The reason for flaring the centralizing device in both directions is to permit the actuating movement of the disk 131 and a returning or ineffective movement of this disk.

The disk 131 forms a part of the controlling mechanism and is arranged to be given a step by-step movement at the actuation of each of the tabulating keys 16 to bring the typewriter carriage into a new computing zone or column. For this purpose, the controller disk 131 is secured to an escapement wheel 136, which has secured thereto a gear 137 meshing with a rack 138 on a bar 139. The bar 139 is guided for movement on a plate 140 and has connected thereto a spring 141, which is normally under a tension tending to drive the rack bar 139 and thus rotate the gear 137 with the escapement wheel 136 and the controller disk 131. This movement, however, is prevented'by a dog 142 which engages the teeth 149 of the escapement wheel 136. The dog 142 is mounted on a bar or rail 143, which is universal to all of the tabulating keys 16, with the possible exception of the millions key, indicated at 144.

The universal bar 143 is supported by a pair of spaced arms 145, which are mounted on a rock shaft 146, so as to form a universal frame. This frame is normally held in a raised posltion by one or more springs 147 coiled about the shaft 146 and engaging under the arms 145.

lVhen the universal frame, including the universal bar 143, is in its normal raised position, the dog 142 will have the toe 148 thereof in engagement with one of the teeth 1490f the escapement wheel 136, preventing rotation thereof under the tension of the spring 141. As soon, however, as one of the tabulating keys 16 is depressed, it will engagethe universal bar 143 and depress the same against the tension of the springs 147, thereby moving the toe of the dog 142 out of engagement with the escapement wheel 136. Before, however, this wheel can complete its movement, a second pawl or dog 150, which is somewhat shorter than the dog 142, will be depressed to bring the toe 151 thereof into the path of movement of the next tooth 149 on the escapement wheel 136, locking the escapement wheel and the controller disk 131 from further rotation.

When the tabulating key just depressed returns to its normal position, the universal bar 143 will likewise return, carrying both the dogs 142 and 150 with it, thereby removing the dog 150 from engagement withthe tooth 149 on the escapement wheel 136, and bringing the dog 142 into engagement with this tooth, so that during one up-anddown movement of a tabulating key, the dogs will alternate in action, permitting a single step movement of the escapement wheel 136 corresponding to the distancebetween two of the teeth 149, and thus permitting a single step movement of the controller disk 131.

The dogs 142 and 150 are connected to a sleeve 152, which is common to both of them, and which is further pivoted on the bar 143, so as to admit of a swinging movement of the dogs relatively thereto. This swinging movement may be made use of in permitting a backward rotation of the escapement wheel 136, the teeth 149 thereof being inclined on their rear surfaces to cam the dogs aside.

In order to permit this movement of the dogs and yet maintain them normally in cooperative relation with respect to the teeth 149, there is provided a spring 153, which is secured to a lug 154 on the bar 143 and extends through an opening 155 in one of the dogs, 142. Inasmuch as the dogs are secured together by the common sleeve 152, the spring 153 will answer for both of them. The inward motion of the dogs under the urging of the spring 153 is limited by a stop 190.

After a single series of controlling ac tions of this controlling mechanism has been effected, as, for example, when a complete line of numbers has been written on the typewriter, then it. is necessary to retension the spring 141 and return the controller disk 131 to its normal position. For this purpose, the bar 139 may be provided with a hand-hold 156 at one end thereof, so that the operative can grasp the same and return the bar 139 to its original starting position, and thus reenergize or retension the spring 141 connected thereto. Inasmuch as the rack of the bar 139 still meshes with the gear 137, then this gear will be rotated in a counter-direction, that is, in the opposite direction to that shown by the arrows in Fig. 4, so that the escapement wheel 136 and the controller disk 131 will be returned to their original starting positions.

lVhile the controller disk 131 may be of any suitable form, the type adopted in this instance consists in having a flat disk with a series of perforations therein arranged in a circle. Every other perforation may be used for the position-determining buttons 130 on one side of the disk, and the intermediate perforations may be used for the positon-determining buttons on the opposite side of the disk. That is to say, with two computing heads, the alternate holes or perforations correspond to the controlling buttons on opposite sides of the disk and thus to the two shifters 125 and 126 and their accordant computing heads.

The position-determining buttons are shown in the form of screw-bolts, each provided with a head 157 (Figs. 9 and 10) and an eccentrically-located shank 158 of a size to conform to the holes or perforations in the disk 131. The shanks 158 are screwthreaded to enable the attachment thereto of locking nuts 159, which secure the positiondetermining buttons in any adjusted position. The adjustment of the buttons and the locking of them in position may be aided by a screw-driver slot 160 provided in each head 157.

The position-determining buttons 130 are to be located on the disk 131 in one of three positions corresponding to adding, neutral and subtracting. By reference to Fig. 9, these three positions will be noted for the top side of the disk. 161 indicates a position-determining button in its adding adjustment, that is, with the head 157 thereof swung to its position farthest from the center of the disk 131; 162 indicates a position-determining button in its subtracting position with the head 157 swung to its position nearest the center of the disk 131; and 163 indicates the adjustment of the positiondetermining button to a location corresponding to a neutral condition of the computing head, that is to say, with the head 157 thereof located in a position midway between its extreme outer and inner possible locations. Of course it is to be understood that the heads 157 of the position-determining buttons are considerably larger and deeper than the nuts 159 which hold them in posi-' tion, so that the centralizing element 128 I state of the computing heads manually independent of the automatic controlling mechanism, as in case it is desired to correct an error. In such an event, the manual levers 118 and 119 may be manipulated in such a manner as to leave the automatic controlling mechanism in the same condition. For this purpose, the shifters 125 and 126 are composite, that is to say, formed of two parts having a relative movement when neoessary. In other words, each composite shifter includes a bell crank lever 164:, to one arm 165 of which is secured the centralizing element 128 or 129. The other arm 166 of the bell crank lever has a mate in an arm 167, which is pivoted to the same stub shaft 127 in close juxtaposition thereto. The arm 167 is normally connected to the arm 166, so that the two will move together as a unit by a latch 168, which is held in its locking position by a spring 169. The arm 167 has a perforation 170 in which the link 123 or 124C is hooked to form the connection to the corresponding lever 118 or 119.

The latch 168 is pivoted to an extension 171 on the arm 167, and is provided with a beveled locking tooth 172, which engages a corresponding socket 173 in the arm 166.

This yielding connection between the two parts of the shifting lever permits the forcible disengagement of the latch 168 and thus of the arm 167 from the arm 166 when the associated lever 118 or 119 is manipulated to vary the state of the associated computing head from that determined by the particular positionii'ig button 130 in engagement with the centralizing element 128 or 129. In other words, by this forcible disengagement, the character of computation can be controlled manually independent of the automatic controlling means.

In addition to the fact that the latch 168 may be'readily cammed out of its socket while the bell crank lever 164: of the shifter is held stationary by engagement with one of the buttons 130, this latch may also be forced into position'when the corresponding lever 118, 119, is returned to a position cor responding to the position of the bell crank lever 164. For this purpose, the arm 166 of the lever 164;, which is spread out at the point of engagement with the latch 168, is beveled at both sides of the notch 173, as at 17 1 and 175, to admit of the camming by of the latch on a re-mating relative movement of the arms 166 and 167. The limits of movement of the shifter may be determined by stops 176. V 7

It might happen that the operative after completing a line of writing and running through the line of computing zones, would forget to return the rack bar 139 at the same time that the typewriter carriage is returned to its starting position for a new line. A

lock is therefore provided to guard against with a series of perforations 177 arranged at intervals corresponding to the step movements of the escapement wheel and of'the controller disk 131, and preferably in register with the teeth 1 19 of the escapement wheel 136. These perforations may be numbered from 0 to 10 to correspond to the initial position of the typewriter carriage and the several possible computing zones thereof. The alternate perforations for the positioning-determining buttons on the controller disk 131 may be correspondingly numbered, so that the stopping points of this disk will accord with the different columns or zones as typewritten. A look 178 may be secured, by means of a bolt 179, at any one of these points by passing the bolt throu h one of these openings 177. The lock 178 projects beyond the root circle of the escapement wheel, and, in fact, conforms at its outer end to the particular tooth with which it is brought into register, on one side thereof, that is, on the inclined or back side thereof. This lock, however,projects beyond the locking side of the tooth with which it is cooperating, so as to prevent the dog 142 from being depressed out of the path of this particular "tooth.

It will be seen that after the controller has been moved step by step to the end of the desired controlling sphere thereof, then the dog 1 12 will be located directly above the guard or look 178, preventing a further actuation of any of the tabulating keys 16. In this instance, the guard is shown as being located at the fourth station corresponding to four computing zones or columns, beyond which the carriage cannot be tabulated. and the computing mechanism controlled in its state until the automatic controlling mechanism has been returned to its initial position.

In preparing the machine for operation, the position-determining buttons 130 are properly located on the disk 131 for the sequence of computing actions desired of the computing heads. In this instance, the top side of the disk 131 controls the upper computing head and the bottom side of the disk 131 controls the lower computing head, there being but two heads shown. If it is desired to add in any particular zone, the button will be located in the position illustrated in Fig. 9, at 161. If it is desired to have the computing head silent in any zone a button in a position such as that indicated at 163, will be used. If, on the other hand, it is desired to subt act in any computing Zone, the positioning button will be adjusted to a location shown at 162.

Vhen the buttons for the successive steps or stopping points of the controlling mechanism have been properly adjusted, it may be determined how far the computing mechanism is desired to be used. That is to say, if, as illustrated in the drawings, it is desired to have four computing zones or columns, there will be placed on the rack 20 of the carriage, four of the carriage stops 19, as illustrated in Fig. 3, so that the carriage will be positioned by an actuation of the tabulating keys for four different columns or zones. The guard or lock 178 can then be positioned on the escapement wheel 136 at the number 41 position corresponding to the termination of the fourth. step movement of this controlling mechanism. That is to say, the 0 position corresponds to the initial position of the carriage; the 1 position corresponds to the first computing zone; the 2 position to the second computing zone, and so on. Thecontrolling mechanism is ar anged 'ith the spring 11-1 completely tensioned and the tooth 1&9 of the escapement wheel 136 in register with the O position in engagement with the dog 14:2. The carriage is likewise positioned to its extreme location at. the right. The tabulating key 16 is then struck to bring the carriage to the first computing zone or column. This actuation of the tabulating key will not only determine the position of the carriage but will depress the universal bar 1&3 and bring the dog 142 out of engagement with the initial toot-h. 1&9 (at 0 Zone), concomitantly bringing the short dog 150 intothe path of the next tooth.

hen the tabulating key returns, the springs 127 will likewise return the universal frame including the universal bar 143, so that the dog 150 is removed from engagement with the tooth on the escapement wheel 136, and this escapement wheel with the controller disk 131 flies around under the propulsion of the spring 141 until this next tooth which has just escaped past the dog 150, comes into engagement with the dog 142 which by this time has risen into the path of this tooth.

During this movement, the positioning buttons on the top and bottom of the controller disk 131 will engagethe bottom and top of the centralizing elements 128 and 129, and adjust them to positions corresponding to the positions of the heads of these buttons. This movement will be transmitted to the clutch-shifting composite levers 99 and 100, so that the drive and character of drive of the master-wheel shafts and the tensarrying shafts of the computing heads will be determined, and thus the state or character of computation carried on by these computing heads determined.

After the digits of a number to be computed in this first computing Zone or column have been written on the work-sheet on the carriage and run up in the computing heads, then the tabulating mechanism will be again actuated to bring the carriage to the next computing zone or column, which actuation will likewise cause a step movement of the controller or controlling mechanism, to provide a readjustment of the states of the computing heads, if it should so happen that it is desired to change them for the next column. Of course, the positioning buttons in two successive columns might be the same for any one computing head or for both computing heads, so that the mechanism would remain in its state of previous adjustment. This action is repeated for each computing zone or column until the fourth computing Zone or column in the example given, is finished. Then it will be impossible to actuate the tabulating mechanism as the dog 142 will engage the guard or look 178 and be prohibited from any downward movement. This, then, shows that the end of the sphere of control of the controlling mechanism has been reached for the particular adjustment thereof, and that it is necessary for the operative to return the controlling mechanism to its original position and retension the spring 1 17 by actuating the hand-hold 156. This, then, while admitting of the automatic control of the states of a plurality of computing heads for the different zones of columns, prevents an overrunning of this mechanism, and further prevents states becoming discordant with the particular zones of the typewriter carriage with which the successive step movements are intended to accord.

If itshould be desired to manipulate the composite state-controlling levers for any computing head, so as to obtain a state other than determined by the automatic mechanism, as in case itis necessary to make a correction, then the particular lever 118, 119, corresponding to the computing head which it is desired to control, is manipulated, which may be done without a disruption of the mechanism or an interference with the automatic mechanism by virtue of the composite character of the shifters 125, 126.

In case it should be required to actuate the typewriting mechanism to space the carriage without operating the state-controlling mechanism, the millions key could be used, inasmuch as it does not project above the universal bar 143.

It will thus be seen that there is provided an automatic controller or controlhng mechanism for determining the state of a plurality of computing heads according to a determined plan.

Variations may be resorted to within the scope of the invention, and portions of the improvements may be used without others.
