-: The "invention" herein relatesy torn "printing setting up'type'co'ini'nensuufate with the leigf y 'nations' on the fcard and actuante darn'- accin'nul' Computeol and then printed-byfthef' print-ing cumule"ting,r "and rece tacle and are fed to the analyzing mecfianism in which, as shown in said copending application, analyzino pins, which find perforations in the car s being analyzed, pass upwardly therethrough and engage extension pins, Which in turn actuate registering stops 14. After the cards have been analyzed they are discharged into a suitable receptacle.

The first step in the operation of the typesetting and tabulating mechanism, consists in the pushing up of the various sto pins 14 (Fig. 2) by means of the extension ins, which are actuated by the various per orations in the cards as they pass through the machine. A specific description of the stop pins, their supporting means, and the means for returning them to normal position after they have set in motion various other parts of the typesetting and tabulating mechanism is iven 1n said co-pending application.

lghe registering stops 14 correspond in number to the extension pins except that there are no extension pins or registering stops 14 to correspond with the analyzing pins that analyze the zero perforations in the cards. Each row of registering stops 14 has a zero sto 16 associated therewith, which is normal y in zero stopping position and will remain so unless one of the registerino` stops 1 to 9 inclusive associated therewith 1s actuated and therefore it is unnecessary for a zero analyzing pin to actuate or cooperate with a zero stop 16.

Herein the part of the accounting machine to the left in Fig. 2 will be considered the forward part of the machine while that to the riffht in Fig. 2 will be considered the rear of the accounting machine.

The registering stops 14 in the present instance are arranged in a suitable number of rows having ten stops in each row, the stops of each row corresponding to the integers 9 to 1 inclusive and zero, the stop 9 being at the forward end of the machine and the zero stop at the rear ond thereof. The stops 14 corresponding to the integers 1 to 9 inclusive are each composed of a flat body portion comprising a head having forwardly projecting portion 17, a cam face 18, a small rectangular shaped abutment 19 made on one side of the pin and adjacent to its upper end, an elongated body portion 20, and a lower restoring notch 21 on the rear edge thereof. The stops 14 have their projections 17 normally resting on an upper stop plate 22 and extend down through a lower stop plate 23. The stop plates 22 and 23 have `openings therein corresponding in number to the stops 14 and zero stop 16 in registry with each other whereby the pins may reciprocate through them.

The stop plates 22 and 23 are indirectly sup orted on the cheek plates 34.

Tlhe zero stops 16 are formed somewhat similar to the stops 14 and have a forward rojection 36 at their upper end and a cam ace 37 on the forward edge extending upward from the extension 36 and a recess 38 in its rear edge.

Means is provided for anchoring the varlous registering stops 14 that are actuated by the extension pins and also holding the zero stops 16 in position for causing an actuation of the corresponding typesetting and tabulating elements. This anchoring means is fully shown and described in said co-pending application and is not claimed herein.

The zero stops 16 are normally disposed in raised position and whenever a stop 14 is actuated to the raised position by means of the plungers 12, simultaneously therewith the zero stop 16 in that row will be lowered.

In order to accomplish this result an elongated lever 62 (Fig. 2) is provided for each row of stops 14, whlch lever is provided with a plurality of lugs 63 arranged in a straight line and all extending in the same direction, each lug 63 also extending into one of the recesses 21 of the stop 'pins 14. The front ends of the levers 62 are pivoted on a suitable shaft which is supported within the cheek plates 34 of the machine. The rear ends of the lever 62 are provided with lugs 66 which are slidably and ivotally mounted in slots 67 at the rear en s of the links 68, which links are pivoted on a shaft 69 supported by the cheek plates 34. The front end of the links 68 are provided with lugs 70 which are arranged to slide within a recess 38 formed in the rearedge of the naught stops 16.

Supported by the cheek plates 34, is a comb plate 71 the upper end of which is Islotted to permit the lever 62 to extend therethrough and be guided thereby. A coil spring 71 is strained between the lever 62, and the lower edge of the said plate 71 for the purpose of normally raising the lim naught stops 16 into the position shown in` Fig. 2. When one of the stops 14 is raised, the actuation of the lever62 by means of the cooperation of the slot 21, carried by the stop, with the plug 63, carried by the lever, will cause the links 68 to be actuated which will in turn lower the stop 16 of the row in which the stop pin 14 has been raised.

As has beenheretofore described the first action that takes place When the machine is started, is the raising of the various stop pins 14 by the actuation of the extension pins which. are in turn controlled by the perforations in the cards passed through the machine. After a card has transferred its data to the pins 14 by raising them, and has assed from the machine, means is provided or returning the pins 14 to their normal lower position for actuation by the next incoming card. This means forreturning the stop pins to their normal position is described in detail in said co-pending application.

A lever 72 is provided having a bifurcated lower end 73 which straddles the main drive shaft 74 which provides the driving means, for the entire typesetting and calculating mechanism. This lever 72 is provided with a pin 72 upon which is rotatably mounted a roller 75 which is arranged to roll within ,2; cam slot 76 in a suitable cam on the shaft There is provided and described in said co-pending application, though not shown or claimed herein, a means operatively connected with said lever 72 whereby the stops 14 which have been set by the perforated cards, are released by the aforementioned anchoring means after they have performed their functions. As soon as the pins 14 are freed, the lever 62 will be pulled down by means of the coil spring 71', and in its downward movement the lugs 63 carried thereby will engage the slots 21 of the stop p-ins 14 and pull them downward to their normal lowered position.

The naught stop pins 16 are arranged to normally retain or hold back reciprocating rack bars 82, which during their reciprocation actuate typesetting elements. As heretofore described, the raising of a stop pin will lower the naught stop so that upon the actuation of a stoppin, the reciprocating rack bar associated therewith will be released and be permitted to run forward until it engages a raised stop pin 14. `During their reciprocation the reciprocating members have actuated the type settingelements and upon being stopped bythe raised v'stop pins will hold the typesettingelements in a position to set type corresponding with thenumber of the raised stop pins. lA detailed description ofthe reciprocating rack bars and their connection and cooperation with,

the naught stops, stop pins and typesetting elements willnow be described. i

The reciprocating rack bars each coniprise a. relatively thin bar shaped bbdy portion 82 which is provided with a longitudinal slot 83 that is adapted to slide along a transverse bar 84, secured to the cheek plates 34. A transverse bar 85 is also provided which serves a support for the forward end of the bar 82. The bar 85is rigidly fastened to the cheek plates 34. A second relatively -thin bar shaped member 86 is pivted at its front end to a pivot 87 carried by the front end of the bar 82. The upper edge of the bar 86 is provided with a recess 88 to receive a bark 89 which is reciprocated by 'means hereinafter to kbe described, andduring its reciprocation will move. both the bar 82 and the bar l86 connected thereto. The

bar 86 is provided with a cut away portion 90 so as to lessen the depth of the said bar to enable it to slide above the shaft 84 and at the same time permit the outer ends of the bars 82 and 86 to remain parallel with each other. A spring 91 is strained between the free end of the bar 82 and a vertirally extending arm 92 which is made integral with the inner end of the bar 82.

.A horizontally extending pin 96 is carried by one side face of the bar 82 which is adJacent to the bar 86 and pivotally mounted'upon which .is a bell crank lever 97, the outer end of which is provided with a horizontally extending pin 98 which is reciprocatively movable in a slot 99 made in the bar The otherend of the lever 97 is provided with a. lug having a cam front face 101 and a right angular notch forming a rest 103 (Fig. 2). The upper edge of they bar 82 is provided with an upstanding abut- .ment 104 having a vertical front wall 105 and an inclined or cam rear wall 106. The bottom edge of the bar 82 is provided with an abutment 104 provided with a vertical front wall 105 and a cam rear wall 106 the purpose of which will be hereinafter set forth.

The bar 89 which as heretobefore described, is for the purpose of reciprocating the bars 82 and 86 is itself reciprocated in the following manner, reference especially being made to Fig. 1.

The bar 89 which is rectangular in cross section is rigidl connected at each end to a slide 107, whic is reciprocatable between rollers 108 forming guideways therefor. A slot 109 is made in each cheek plate 34, which receive a vroller 110 revolubly mounted on the shaft 111 secured to the rear end of the said slides .107. The front end of the v'slides 107 are provided with horizontally roller which arranged to roll within a suitable cam groove in a cam carried on the shaft 7 4.

Returning now to the rack bars 82, the top edge of the forward portion of the said bars 82 are provided with. gear teeth 119 v which are in mesh with a gear 120 (Fig. 2)

secured to type segments 121, which have bearing on a transverse shaft 122 carried between the cheek plates 34 which segments have an arc shaped rear edge provided with gear teeth 123 which will hereafter be described. The front` edge of the segments 121 are also made arc shaped and are provided with rectangular notches to receive the upturned ends of type 126. The rear ends of the type are also provided with a laterally turned ranged to fit within rectangular openings in said segments. A fiat arch shaped plate 128 is arranged to fit against the type 126 and to hold their laterally turned portions 1n engagement with said notches and openings respectively. Reading from the upper edge of the type carrying portion of the segment, the

type carried thereby read in sequence, the

first type being zero, the next 1 the n ext 2 etc., the last type on the segment being numbered 9.

A description of the operation of the stop pins, the reciprocating rackbars and the oscillating type segments will. now be given. ln the position shown in Fig. 2 all of the stop pins 14 are down and all of the naught stops 16 are in raised position.\ When the stop pins 14 are in their initial raised position the vertical walls 105 of the abutment 104 fit within the notches 38 in the upper end of the naught stops and consequently holds the bars 82 and their associated bars 86 in their extreme rearward position, and also retain all of the type segments in a position to print ciphers. Although each spring 91 is exerting tension to lift the bars 86 nevertheless this bar is held to the limit of its downward movement due to the fact that the rest 103 carried by one end of the bell crank lever 97 will rest on top of the naught stop 16 which holds the said bell crank 97 at the limit of its downward movement by means of the pin 98 carried by the member 82 and the slot 99 in the bar 86. As soon as any of the stop pins 14 are raised by means of said pin extensions, actuated by means of a card passing through the-machine, the naught stop 16 in that row is lowered simultaneously, as has been heretofore explained. The downward movement of the naught stop 16 freesvthe abutment 104 permitting the bar 82 -to be carried forward. Simultaneously with the disengagement of the abutment 104 and the stop pin '16, the lever 86 is raised by means of the spring 91 which in its upward movement moves the notch 88 to fit against the yfront side of the reciprocating bar 89. When the parts are in their normal' position, the bar 89 is at the limit of its rearward movement and rests against the vertical wall 105 of the abutment 104. As soon as the notch 88 engages the reciprocating barv 89,1the said bar is locked between it andsaid vertical wall 105 so that when the said bar 89 is reciprocated by means of the lever 114 and its associated parts, heretofore described, the bars 82 and 86 will also be moved forward. Simultaneous with the forward movement of the bar 86 the bell crank 97 is moved downward. As the bar 89 is reciprocated by the lever 114, the said bars 82 andl 86 will be carried with it until the cam face 101 ofthe bell crank engages the rectangular abutment 19 ortion 127 which is ar-l of the stop pin 14 which has been raised. This contact lifts the bell crank 97, and lowers the rod 86 awainst the tension of the spring 91 which in its downward movement releases the reciprocatin bar 89. As soon as the bell crank 97 has n raised the vertical wall 105 of the abutment 104 will engae the rear end of the raised stop pin 14 an prevent the bar 82 from moving further. Since the reciprocatin bar 89 is released as the bar 82 is stoppe the bar 89 will continue itsforward movement although the bar 82 and the lever 86 have been stop ed. This is for the urpose of freeing the ars 82 and 86 from t e reciprocating member 89 as they engage the stop pins in their forward position and thereby permitting the bar 89 to carry all of the bars 86 forward which have not been freed therefrom in the manner heretofore described.

Due to the rack teeth 119, as the bar 82 is moved forward, the type segment 122 is oscillated through the medium of the gear wheel 120 as heretofore described..

After all of the type segments have been set by the stop pins 1n position to print data transferred thereto from the cards, means is provided for locking and alining the type segments so that they may not move during the printing operation. This locking and alining means will now be briefly described.

The extreme upper end of the lever 72 is provided with a knife shaped transversely extending arm 130 slidably mounted within a slot 131, within the cheek plates 34. Both the slot 131 and the knife shaped member 130 which is herein termed a detent, are arranged radial to the gear teeth 123 of the type segments and lock the said segments from moving, and line up the type carried thereby. The lockin of the printing segments and the releasing of the stops 14, is brought about simultaneously so that the reciprocating members may be free to be moved back to their original position after printing without engaging any stop pins' whatever except the naught stops 16. A mechanism is provided for preventing all of the cipliers `to thel left of the digit last set up bythe sto pin from being printed. Or in other wor s, a mechanism is provided for retracting all of `the segments out of printing position which have been left' against the naught stops as the released bars 82 start on their forward movement. Since this mechanismisdescribcd in said co-pending application and does not directly relate to the non-printof items that are accumulated, a description thereof is not given here. The parts 132, 139 and 183 relate to this mechanism.

Means is provided for lowering the bars 86 so as to raise the bell cranks 97 so that when the bars reach the limit of the rearward stroke the rest 103 will be in vposition to rest upon the' top of the naught stops' which are in their raised position as shown in Fig; 3.

The means for lowering the bars 86 and lifting the bell cranks comprises a transverse bar 163 (F'i 2) which isarranged above the upper e ge of the bars 86 being rigidly carried by the upper ends of slide levers 164 arranged adjacent to the inner face of each cheek plate '34, which, during their downward movement, slide the bar 163 in slots 165 made in the said cheek plates.

vThe slots 165 are of a length suliicient to permit the bar 163 to move down in contact with the upper edge of the bars 86 and force them downward. The lower ends of the levers 164 are rovided with pins 166 which project throng slots 167 in the cheek plates 34 and 35. The levers 164 are reciprocated up and down by means of levers 168 arranged adjacent to the inner face ofthe' cheek plates 34 and have bifurcated rear ends 169 which straddle the pins 166. The levers 168 are pivoted at 170 to each cheek plate 34 and are oscillated by suitable con-y 4, plates34 respectively as is shown in Fig. 2.

At the lower part of the forward end of the cheek plates 189 is mounted a transverse horizontally extending shaft 192, `the outerl ends of the shaft 192 projecting through longitudinal slots 193 (Fig. 1) in the cheek plates 34. Upon the shaft 192 are mounted spacing collars which are rigidly held together between the cheek plates -191 by means of collars 1494 which clamps against the outside of the cheek plate '191 by means of a nut 195. Revolubly mounted in each of the spacing collars are gear wheels 197 each having ten gear teeth 198v thereon. Une

side face of veach of the gear wheels 197 isprovided with an annular collar 199 having on .its periphery an abutment 200 providing fa radial face 201 and an inclined cam face 202. The abutment 200 is made on the periphery of the collar 199 so that it lies adjacent gear tooth of the gear teeth 198. The collars 199 are also provided with an 'abutment 203 having a rounded face, and

this abutment is arranged adjacent gear tooth and diametrically opposite the abutment 200. The functions of the abut- 1Ifnenlts 200 and 203 will be hereinafter set ort The rear end of the cheek plates 189 are provided with longitudinal slots 205 which receive a guide rod 206 rigidly carried by the cheek plates 34 and 35.

Means are provided for reciprocating the accumulating carriage backward. and forward on the guide rod 206 and the shaft 192 which carries .the accumulating gear wheels. This means comprises levers 207 (Figs. 1 and 3) which have their vupper ends 209 respective y supporting the shaft 192. The lower ends of the levers 207 are pivoted to stud shafts 211 carried by levers 215 which have horizontally extending portions 217 (Figs. 4 and 5) which-extend inwardly toward each other and are provided with vertically extending relatively rectangular shaped plates 219 pinned together at their upper and lower ends by means of pins 221. The said plates 219 are provided with registered openings 223 and 224 to receive a cam shaft 225, loosely mounted-on a shaft 226 which passes throu h its center. .Rigidly mounted upon the s aft 226 are collars 227 and 228 (Fig. 3) which abut against the ends ofthe cam shaft 225 and are held in locked position by means of set? screws 229. The collar 227 is rovided with an annular groove 230 to recelve the bifurcated end 231 (Fig. 2) of a lever 232 which is pivotally mounted at 233 to the frame work 234.

The base carries the entire typesetting and accumulating mechanism and also the reciprocating printing carriage 13. The lever 232 intermediate its ends is provided with a rectangular cage 235 within the walls of ywhich is reciproca-tably mounted a.

lunger 236 having a cam engaging head on its upper end. A spring 237 is compressed between the inner face of the said cam engaging head and the wall of the rectangular cage. The spring is normally held compressed by means of a bell crank 238 pivoted to the lever 232, one end 239 of which is adapted to engage a collar 241 carried on the inner end of the reciprocating plungeil 236. The other arm of the bell crank 239 upon being pressed, disengages the end 239 from the collar 241 and permits the plunger to be forced upwardly under action of the spring, whereupon the plunger enters a spiral cam groove 244 (Fig. 6) in the periphery of the cam 77. As thc cam head runs in the groove 244 the lever 232 will be pushed to one side by the said groove and thereby cause a sidewise movement of thc lever 232 which will slide the cam shaft 225, for a purpose to be hereinafter set forth. As the cam reaches the end of its revolution, an abutment 245 secured therein and having an inclined face 246 will engage the end of the plunger head and force it downwardly, whereupon the collar 241 snaps in back of the said lever 238 and is held in its locked position (Fig. 2). A coil spring 248,

strained between the end of the lever 233 lil and. the upper edge or the lever 232, .non mally holds said end in an upward position to be engaged by the collar 241. rlfhe levers 207 and 208, as before described, are for reciprocating the accumulating carriage. These levers are pivotally mounted upennJ transverse` shaft 250 which is mounted in the cheek plates 34. Between the said levers 207 and pivotally mounted on the shaftl 250 are the inner contacting ends 251 of le- v vers 253 and 254 respectively which have the revolution of the said cam, transmits a rockin i motion to the lever 254 which throng themedium of the levers 215 and 207 reciprocates the accumulating carriage. When the said accumulating carriage is being reciprocated by the lever 254, the4 accumulating elements thereof are actuated for accumulating purposes only, as will be hereinafter more fully explained, and consequently the lever 254 may be termed`the accumulating lever. A coil sprlng 263 is strained between ears 2645 carried by the lever 207 the lever 215 for the purpose of normally holding a lug 266 carried by the lower edge of the lever 207 against the lowei` edge of an opening 267 made in the upper end ofthe lever l215. The springs Y263 are of such 'strength vthat the levers 207 and 215 are for all lpractical purposes, as though the 1 were made as a single lever.

he roller 258 is revolubly mounted in a cam groove 268 of a cam 269 which, during the revolution thereof, will transmit a rocking motion to the lever 253, which motion, through the medium of levers 207, will reciprocate the accumulating carriage. Since the reciprocating carriage is reciprocated by the levers 253 only when taking the total this lever 253 may be termed the total taking lever.

The camshaft225 is provided with an annular groove 271 havlng inclined side walls 272 and 273 respectively. The openings 223 and 224form bearings for the cam shaft 225. The groove 271 is of a width greater than the space between the levers 253 and 254 so that only one of the said levers at a time can have the walls of its opening 255 or 256 in contact with the periphery of the cam shaft 225.y As for instance, when the cam shaft is shifted by the lever 232 and its associated parts, as heretofore d scribed, andthe levers 253 -has the walls of ts open'.-`

is loose in the groove of the cam shaft 225 but will be iree within the groove 271 (Fig. 5). W'hen the cem shaft 225 is shifted in the reverse direction, the levers 253 and 254 occupy the position shown in Fig. 4, in which case the lever 253 is shown loosely mounted in the 'roove 271 while the edges of the opening or' the lever 254 are in engagement with the periphery of the cam shaft. Since both of the levers 253 and 254 are always being oscillated through the action of their lever which is loosely mounted in the groove 271 it may frequently not be in a position where its opening will exactly register to vrecevethe cam shaft 225 when it is moved sidewise. Due to the inclined walls 272 and 273 of the annular groove 271, however, when the cam shaft 225 is moved sidewise in the opening in one ofthe levers 253 or 254,v the edges of the said opening will slide upon the inclined walls 'of the annular groove 271 until the cant sha t. Whenl the cam shaft is moved sidewise so as to place the edges of the opening of the levers 253 or 254 1n engage-l ment with the periphery of the cam sha-ft, a positive connection vwill be made between the said lever and its cooperating levers 215 and the accumulating carriage reciprocated. At this time the other lever whose opening 271 has no operative eect onfits associated lever 207 for reciprocating the accumulatln carriage. From the above it is apparent t at the levers 253 and 254 are selectively locked, so to speak, to the cam shaft 225 for reciprocating the accumulating carriage, the lock and release being actuated by the shifting of the cam shaft 225.

The purpose of the dii'erent cycles of the reciprocation of the accumulating carriage by two different levers, and its effect upon the accumulating and printing mechanisms will be hereinafter exl lained.

Now will be consi ered the position of the parts in which the lever 254 is locked on the cam shaft 225 and the accumulating carriage is being reciprocated thereby for 'the purpose'of accumulating. At this time the elements of the accumulating mechanism occu y the position shown in Fig. 2.

As is s own in this figure, the printing operation has been completed,I and the other elements of the printin mechanism have beenso set to permit a grec passage Vof the reciprocating members 82 in a rearward directlon. Be ore the members 82 move rearwardly however, the lever 254 is operated which. will reciprocate the accumulatmg carriage 'forwardly until the accumulator wheels 197 have been brought intocontact with the gear teeth 123 .of the type seg'-,

come vin position to receive the los ments. The rearward movement of the bars 82 will then rotate the accumulating gear wheels 197 and turn the teeth thereon to an extent which corresponds with the type last set up by the type segments.

When the rack bars 82 have reached the limit of their rearward movement, the lever 254 is again rocked to reciprocate the accumulating carriage rearwardly and thereby disengage the accumulating gear wheels with the gear teeth of the type segments, and bring the said accumulating gear wheels into engagement with a transverse bar 272 which is carried by the cheek plates 34 and holds the said accumulating gear wheels against accidental shifting.

This reciprocation of the accumulating carriage backward and forward and the engagement and disengagement of the ac cuxnulating gear wheels with the gear teeth of the type segments takes place as the bars 82 are at rest.

However, lwhen any of the accumulating gear wheels havemade a complete revolution the inclined wall 202 (Fig. 2) of the abutment 200 carried by the said. gear wheel has been brought into engagement with the inclined wall. 273 made on the lower end 274 of an L shaped lever 275, the said lever is rocked upwardly on its pivot 276 against the action of a coil spring 277 strained between the lever 275 and a transverse rod 276 carried between the cheek plates 189, normally holds the lever 275 in a horizontal position. In its horizontal position, the lever 275 holds a vertically extending lever '278 to the limit of its upward movement,

the upper edge of the leverA 275 engaging a lip 279 carried by the side of the lever 275 to hold it in its said upward position against the tension of -a' coil spring- 280 strained between the said lever and a transverse rod 281 carried between the cheek plates 189. A horizontally disposed comb plate 281 is carried between the cheek plates 189 forms guideways for the vertical extending levers 278. Pivoted to the lower end of thelever 278 is a horizontal lever 283 which is pivotally connected to the lower end of a lever 285 which is provided with an enlarged slot 286 receiving the transverse shaft 276. The upper end of the lever 285 is shaped to form a lever 287 which extends rearwardly in a relatively horizontal direction and is pivotally mounted upon a transverse rod 289. A spring 290 carried between the lever 285 and a transverse rod 291 carried by the cheek plates 189 normally holds the outer end of the lever 287 in a downward position. The said outer end of the lever 287 is slidablyl mounted in a comb plate 292 and carries on its outer end a revolubly mounted roller 294 adapted to engage a stepped cam plate 295 provided with cam surfaces 295 which plate is reciprocated back and forth for lifting the roller 294 and rocking the lever 287 against the tension of the spring 290. The cam plate 295 is disposed between the cheek lates 34 and carries at its side edges ro 1ers 296 which are adapted to roll in longitudinal slots 297 (Fig. 1) in the cheek plates 34.

The meansA for reciprocating thel canr plates 34. The lower ends of the levers 307 are ifurcated as at 310 to straddle a transverse shaft 311 reciprocated in 'parallel slots 312 (Fig. 1) in the frame work 234. 'The transverse shaft 311 passes through the entire machine and is arranged to receive the levers 307 of each independent unit or zone. Levers 313 arranged on each side of the machine have one end 314 pivotally mounted on the transverse shaft 311 and their other ends provided with a longitudinal slot 315 to receive the main drive shaft 74. This end of each lever 313 is provided with a revolubly mounted roller 318 which is arranged to rotate in a cam groove 319 in the cam 77. As the main shaft 74 is revolved', through the lever connections heretofore. described, the stepped cam plate 295 is reciprocated back and forth. Due to the arrangement of the pinion 306 and the rack bars 298 and 305, the movement of the rack bar'298 is in ratioiof two to one to the movement of the pinion 306 on the rack bar 305.

Returning now to the L shaped lever 275, it will be seen that means is provided for locking the rear end of this lever in a downward position when the vertical portion 275 thereof has been raised by engagement with the abutment 200 carried by the accumulative gear wheels. This means comprises a belll crank lever 320 (Fig; 2) pivoted upon a transverse shaft 321 carried by the cheek plates 169.I Horizontally disposed comb plates 322 guide these levers during their movement. A coil spring 324 strainedl between the upper end of the lever 320 and al transverse shaft 325 carried by the cheek plates 189 will normally pull the upper end of the lever 320 forwardly and hold itagainst the inner end of the lever 275. W'hen the lower end of the lever 275 is raised as heretofore described,-the vertically extending portion 326 -thereof will snap within a notch 327 formed in the front edge of the lever 320 and hold the said portion 326 in its downward position. The other arm 328 of the bell crank 320 is adapted to come in Contact with the transverse shaiit 206 and upon doing so will move the upper end of the lever rearwardly against the ten sion of the spring 325 releasing the vertically extending portion 336 of the lever 275 from the notch 327 and permit the said lever 275 to oecup its horizontal position under the action oiA the spring 277.

A description of the operation of the carryover mechanism which has just been above described' will now be given. After the accumulating gear wheels have made a complete revolution and the abutment 200 thereon comes in contact with the cam face 273 ofthe vertically extending portion 274 of the lever 275 the said lever will be rocked about its pivot so that its inner end is low is associated.

ered. The lowering of the inner end ofthevlever 27 5 permits the verticall extendrod 278 to be drawndown un er action of the-spring 280 so that the lever 283 will be dropped down in frontof the abutment 104 carried by the reciprocating bars 82.

When any one of the accumulating gear' wheelghas made a complete revolution the reciprocating bar 82 associated therewith will of necessity be in its extreme rearward position. Both the vertically extending lever 278 and the inner end of the lever 275 descend simultaneously, the lever 275 bein locked in its downward osition by means o the bell crank 320 and t e vertical lever 278 being held in its downward position by means of the coil s rin 280. When the parts are in the position a ove described, the reciprocating cam late 295 is moved forwardly by -means o the levers 298, 307 and their associated elements. A forward movement of the cam plate 295 will engage the inclined cam surface 295 thereon with the roller 294 carried by the inner end of the lever 297 thus raising the roller. The lifting of the roller 294 will rock the lever 285 about its pivot 288 thereby forcing the lever 283 pivoted thereto in a rearward direction and bringing the innerV end of the lever 283 into engagement with the abutment 104 made on the upper edge of the reciprocating bar 82, and force the said bar backward a distance suiiicient to turn the gear wheel 120 to oscillate the type segment a distance suiiicient to rotate back one tooth distance, the accumulator gear wheel with which it Due to the fact that the abut ments 200 are carried by the left hand face of each accumulative gear wheel, the set back mechanism heretofore described of the next adjacent accumulative gear wheel to the left is actuated. In other words, a rotation of one of the accumulative gear wheels will actuate the set back mechanism of the aecumulative gear wheel of the next higher order.

' A brief description of the entire machine thus far described will now be given explaining the sequence of operation of the various mechanisms to print and accumulate the data perforated in the cards which are passed through the machine.

As a card is fed through the machine various stop pins 14 are elevated corresponding with the various perforations of the card. The elevation of the stop pins 14 will lower the naught stops 16 in the rows in which the stop pins are elevated. rEhe lowering of the stop pins will permit the reciprocating bars 82 associated therewith, and these levers will depress all of the levers 132 to the right thereof which have not been depressed by the forward movement of the reci rocating bars associated therewith. All of t e levers 132 however, to the left of the lever 132 which has been depressed by the forward movement of the rack bar will still be in their upright position. While the reciprocating bars 82 which have been released are moving forwardly, these last mentioned levers 132 will be reeiprocated rearwardly by means of the bell cranks 139 levers 143 and other elements associated therewith, which in their rearward movement will force back the bars 82 with which they are associated, and oscillate the type segments actuated by these rack bars downwardly to a non-print position. The bars 82 move forwardly under the action of the reciprocating bar 89 until the abutments 104 carried on their lower edges come in contact with the various elevated stop pins 14 at which time they come to a rest. When the rack bars 82 have come to a rest, the segments associated therewith have been oscillated upwardly a distance suflicient to set the type thereon in consonance with the number of the stop pin 14. When all of the type segments have been oscillated into proper position the detent 130 is drawn down into engagement with the gear teeth 123 on the type segments and alines and locks them so that they cannot be moved during the print operation. Sim ultaneous with the operation of the detent, the levers 62 and 163 are actuated, the former causing the drawing down of the set stop pins 14 and elevatlng all of the naught stops 16, the latter contacting with the reciprocating bars 86 for lowering them so that on their return movement the bell cranks 97 carried thereby will be in position to rest upon the top of the naught stops 16. The reciprocating printing carriage 13 is then brought into engagement with the t pe segment and an impression made on t for thetype segments is Awithdrawn and the reciprocating bars moved rearwardly under action of the bar 89. The rearward movement of the rack bars 82 will revolve the accumulating gear wheel through the medium of the type segments and rotate the gear teeth thereon corresponding with rthe type printed. When the bars 82 have completed their rearward motion, the reciprocating accumulating carriage 1s also moved rearwardly so as to disengage the accumulative gear wheel from the type segments and to move them into engagement with a transverse bar to lock them against further rotation. All of the elements are now ready for a second forward movement of the reciprocating bars 82, and the above operation continues. When any of the accumulative gear wheels have made a complete revolution, during which timethe bars 82 associated therewith have moved rearwardl into naught stop position, the L shaped bars 275 are rocked, which through the mechanism heretofore described, will move the rack bar 82 adjacent to the left thereof, back one space so that the accumulative gear wheel associated with this rack bar will also be moved back one space, and in this way form the carry over.

The above operation continues as the cards pass through the machine and the items thereon are printed by the type sectors and accumulated on the accumulator wheels until either a total card is fed to the machine or until it is desired to take the total of the data accumulated by operating a total ke manually. A description of this total ta 'ng mechanism will now be given. l

All of the actions heretofore described have taken place when the lever 253, which I term the accumulating lever, is locked by means of the reciprocating cam shaft, to`

the levers 215. When the total is to be taken the key 240 is lifted either manually or by a push rod A controlled by the perforated cards, as is described in my copen'ding application, Serial No. 80,973, filed Feb. 28, 1916. The reciprocating plunger 238 is released, which will spring into the cam groove 244 and upon engaging therewith will rock the lever 232 about its pivot 233 and reciprocate the cam shaft 255 to the position shown in Fig. 5, which will unlock the accumulating lever 253 and lock the total taking lever 254, whereupon the locking of the levers 207 with the other lever 253 will cause the said lever to reciprocate the accumulating carriage forwardly until the accumulator wheels are brought into contact with the type segments.

At the salne time that the cam shaft 2'55 is reciprocated as above described, means is provided for lowering the pins 14 and the naught stops 16 so that the bars 82 will be in a position to move forward. p This means is described in detail in said co-pending application Serial No. 158,142 and need not be described here.

After .the accumulator gear wheels have been moved into mesh with' the gear teeth on the type segments and after both the naught stops and the stop pins have been lowered as above described, all the elements will have been set to permit a forward movement of the bars 82. The bars 82 are moved forward under the action of the transverse bar 89 and its associated elements, the said bar 89 being gripped between the abutments 104 and the notches 88 formed in the'upper edges of the bars 86. The forward movement of the bars 82 rotate the accumulator gear wheels in the direction which is anti-clockwise in Fig. 2, until the radial wall of the abutments 200 come into contact with the rear edgesA of y 'the vertically extending portion of the bar 275. When the accumulating gear wheels have been stopped in the manner heretofore described they have revolved their associated type segments upwardly a distance sufficient to set into printing position the type corresponding with the gear teeth of the accumulating wheels. Since all of the accumulating wheels will not revolve the same distance, but since it is necessary that the bar 89 should move to the limit of its outward movement, means is provided for releasing the said bar from engagement with the notches 88 formed in the bar 86 so that the `bar 89 may slide on the upper edge of the bar 86 as is shown in Fig. 26. This means comprises a lever 350 pivoted to a transverse shaft 351 carried by the cheek plates 189, and is provided on its upper edge with a rounded abutment 353 which is adapted to come in contact with the rounded abutment 203 carried on the collar 199. When the said abutment 203 and 353 come into said contact, the lever 350 is forced downwardly, which will force the bars 86 also downwardly through the mediuiui of an outwardly turned lip 354 formed on the outer cud of the lever 350. The forcing down of the bar 86 as before described, will release the transverse reciprocating bar 8 9 and permit it to move downwardly to the limit of its stroke. When all of the type segments have been set up in the man ner heretofore described, the detent 130 is brought into contact with the gear teeth. of the type segments and locks thel'said segments in printing position. The reciprocating printing carriage 13 is then moved up into engagement with the type and an iinpression Inadeon the paper carried thereby. This impression gives the total of the data accumulated by the accumulative gear wheels. Afterl the vprinting operation is completed the detent 130 is lifted. The

bar 82 then move rearwardly during which motion, the reciprocating plunger 238 is forced back into its locked position as shown in Fig. 2, and the lever 232 has been rocked about its pivot 233 and thereby reciprocated the cam shaft 225 back to accumulating. All of the parts are now in the position to accumulate further data.

It is to be understood that all the description thus .far has been given relative to the operation of one unit of the machine, that is, one printing and accumulating section composed of 9 type sectors and 9 accumulating gear wheels together with their associated and cooperate elements. It is also to be understood, however, that each unit may contain a greater or less number of associatmi printing and accumulated elements. The complete machine, however, comprises a number of units each identical with the unit heretofore described. Means is provided for holding the bars 82, associated with the digits to be kept from printing and accumulating, so that it cannot run forward and backward to set type and accumulate and also to hold the bar 82 back far enough to render the type segment associated therewith to occupy a nonprint position. This means comprises a plurality of latch levers 401 (Fig. 2) which are pivotally mounted upon a transverse bar 402 carried between the cheek plates 34 of the machine. When it is desiredto render a line of digits inoperative, the reciprocating bar 82 associating therewith is drawn back so that the upper end of the latch lever401, which is provided with' a hook 403 will hook over a horizontally extending pin 404 carried by the vertically extending portion 92 carried by the bar 82.

The printing carriage, desivnated generally by reference numeral (Figs. 1 and 7) is located on the printer tabulator base, opposite the type 126.

The carriage is supported at opposite ends on the cam shaft brackets 599 and the lever shaft brackets 601 carried on the base plate of the printer tabulat-or. These brackets are tied together at their upper part by the tie plates 602 bolted at opposite ends to the upper part of these brackets respectivel i.

Tlie lever shaft brackets 601 are provided at their upper ends with guide slots 604 in which are received the L shaped carriage supporting brackets 605 provided at their forward ends with anti-friction rollers 606 adapted to reciprocate in the elongated openings 607.

The supporting brackets 605 are formed near their rear ends with uprights 608 between the upper ends of which are carried the rail supporting bar 609. Between the rear ends of said supporting brackets is carried the arm supportingshaft 610, intermediately of the ends of which are carried the L shaped supported members 612 colnprising the forwardly extending carriage supporting arms 614.

Intermediately of the ends of the supporting bar 609 are carried the forwardly projecting plates 615 which carry at their forward ends the carriage rail 616.

The brackets 605, the -bar 609, the shaft 610, the supporting member 612 and the rail 616 together form a structure which may be called the reciprocatory or movable support for the carriage proper.

The carriage proper comprises end plates 616 held spaced apart by the tie rod 613 and the bracket shafts 629. On the bracket shafts are mounted the rearwardly extend ing supporting brackets 618 each provided with a circular opening adapted to receive the carriage rail 616, this opening being provided with a rearwardly extending slot 614 adapted to rovide a passage for the tie plates 615 w en the carriage is slipped on to the carriage rail. )Vhen the carriage has been put in place it is thus supported by said carriage rails and by the forward ends of the arms 614 engaging under the tie rod 613 at the lower forward part of the carriage.

Between the end plates 617 is mounted the paper roller shaft 620 carrying part of the paper supporting and feeding mechanism to be mentioned thereafter.

The forward edge of the uprights 608 (Fig. 9) of the brackets 605 are provided with inwardly turned perforated ears 621 carrying supporting studs 622 on which are slidably mounted the locating bar 624 pro vided with elongated slots 625 receiving said studs, said bar being also provided with a plurality of holes 626 large enough to receive the heads of the locatin stud 627 fixed on the locating bracket 628 Xed to the bracket shafts 629 connecting the end plates 617.

The carriage may be swung outwardly u pon the rail 616 (Fig. 7) until the stud 627 clears the holes 626, and the carriage then shifted longitudinally until the stud engages in a different hole 625, as desired. The stud 627 and bracket 628 are locked in the adjusted position by means of a locking plate 630 Fig. 9) provided with key slots 631 each aving a large end 632 (Fig. 8) thru which the head of the stud 627 is adapted to pass and with small ends 634 adapted to form shoulders to engage under the head of said stud whereby the stud is positioned by means of a spring 635 tensioned between the upright 608 and the angular manipulating end 636 bent outwardly on said locking plate. The locking plate is held in proper position relative to the locating bar by means of a guide plate 633 secured to an upright 608 (Fig. 9) receiving one end of the locking plate and slotted guide plate 633 secured to the other end of the locking plate and embracing the screw 634 in the ear 621.

The printing is accomplished by the forv ward movement of the paper supporting mechanism which movement brings the paper against type of the type sections. This is accomplished by means of the upper and lower carriage actuating levers 637 and 638 (Fig. 7) pivoted on the lever shaft 639 carried by lever shaft brackets 601. The upper and lower actuating levers are both pivotally mounted on said shaft 639 and when in printing position are locked together as will be explained, and are oseillated by means of the engagement of the cam roller 640 engaging in the cam groove 641 of the printing cam 642 carried on the cam shaft 74. The` actuating levers give one complete cycle of oscillation once for every revolution of the cam shaft 74.

This locking is accomplished by means of locking cones 645, which are shown in un,- locked position in Fig. 8 and must be moved to the right of said figure to lock said upper and lower levers against relative movement. These cones engage in, and when locked, hold in alinement the openings 6484 and 649 of said upper and lower levers, and are carried on the cone supporting shaft- 650 yieldably drawn to unlocked position 'by means of the tension spring 651 secured between the end of said shaft and across piece 652 disposed across the opening 654 (Figf97) in the lever bracket 601. The opening 654 is large enough for the insertion of the cone shaft and cones when assembling the machine.

These cones may be moved to locking position by means of the bell crank lever 655 fulcrumed on the base of the machine and provided at its upper end with spaced ears 656 engaging a transverse pin 657 in the cone supporting shaft 650. This lever is actuated by means of a link `658 pivoted at its lower end to the motive arm of said lever, and at its upper end to the locking lever 660 (Figs. 2 and 7) fulcrumed intermediately as at 661 on the cam shaft bracket 599. The locking lever 660 terminates in a manipulating end 662 (Fig. 1) received in a slot 664 of the locking plate 665, said slot being providedl at its upper and lower parts with shoulder forming recesses 666 and 667 in which said manipulating end may be locked to retain said locking cones in either locked or unlocked position.

On the paper roller shaft 620 journaled in the end plates 617 (Figs. 6 and 7) are disposed a plurality of paper rollers 748. Between adjacent pairs of the paper rollers and loosely engaging said bushings are carried the elastic platen block 758 of rubber or other suitable material.

Partly surrounding or housing the lower part of the paper rollers 748 are the outer paper shields 780 (Fig. 8). These outer shields cooperate with the paper rolls to form guides for the paper 871 (Fig. 7) on which the tabulations are to be printed, said outer shields being continued upwardly in front of the paper rollers 748, whereby are formed extensions 784 (Fig. 8) between which the type of the type sectors pass when the paper is pressed against them by means of the platen blocks 758.

After each number is printed by the type of the type sectors, it is necessary to feed the paper upwardly one or more spaces. This feeding is accomplished by means of engagement of the teeth of the feed ratchet 801, mounted on the shaft 620, by a suitable feed pawl 802 (Fig. 7) pivotally mounted as at 803 on the feed pawl lever 804 fulcrumed intermediately as on the stud shaft 805 and driven by the link 806, in turn driven by the drive lever 807 mounted onV the feed shaft 808, said shaft being actuated by the actuating arm 809 fixed on said shaft and adapted to come into contact with and be moved by the abutment shaft 810 carried on the abutment shaft brackets 811 pivotally mounted on the tie plates 602. As the feed pawl is described in said co-pending application and forms no part of the present invention, it need not be described here. The brackets 811 are limited in their .rearward movement bythe engagement, with the tie plates, of a shoulder 812 formed by the lower edge of the lug 814 laterally turned at the rear edge of saidy abutment shaft brackets, and is yieldably held at its rearward limit of movement by a spring 815 tensioned between said lug and a lug on the rear part of the' shaft tie plate 602.

When the carriage is moved forwardly toward the type sectors the free end faces 816 of the actuating arm 809 engage and push down the abutment shaft 810 against the action of the spring 815 until said end face clears said shaft and permits the shaft and its bracket to be snapped back by the spring 815 until stopped by the shoulder 812.

After the printing has taken placeand the carriage moves rearwardly, the abut ment shaft 810 is engaged by the lower side of the actuating arm 809 whereby said arm and drive lever 807 are raised thus rocking the pawl lever 804 and lowering the pawl 802, thus turning the ratchet 801 one or more teeth.V

The feeding mechanism is yieldably held in position to feed by means of a spring 825 tensioned between the end plate 617 and a perforated ear on the upper part of the inner end of the arm 807.

When it is desired to insert, remove or feed the paper entirely independently of the feeding mechanism just described, I provide a mechanism comprising the paper feed gear 829 (Fig. 8) fixed on the paper feed shaft 620 and engaged by the idler gear 830 rotatably mounted o n the end plate Gl7,.the idler gear being in turn engaged by the knob gear 831 fixed on the stud shaft 805 rotatably mounted in the end plate 617 and carrying knurled knob 832 by which said shaft and gears may be manually rotated.

While the paper is being fed and durlng the time of printinff, itis desirable that it be firmly held against the platens. This is accomplished by means of a clamping mechanism comprising a clampL bar 833 (Fig. 7) carried between the outer en ds of the clamp levers 834 provided with intermediate longitudinal slots 835 loosely receiving the paper feed shaft 620, whereby the paper clamp bar is adapted to move toward and from the paper rollers as well as to revolve with said rollers. The inner ends of the clamp levers are provided with small pins 836 received in longitudinal slots 837 in the lower ends of the springV levers 838 intermediately fulcrumed on the end plates 617 and drawn by a spring 839 strained between the upper end o the spring levers and the u per part of end plates 617, whereby the c amp lever 834 is yieldably drawn downwardly and the clamp bar 833 yieldably pressed against the pa# per and presses the paper against the paper rolls 748.

This yieldable engagement maintains during the printing and feeding of the paper, but after feeding has taken place, as above described, the releasing pin 840 mounted on the cam bracket shaft 841 comes into contact with the abutment shaft 810 and forces the cam bracket shaft and the cam bracket 842to rock rearwardly whereupon the cam edge 843 forces outwardly the pin 836 and therewith the lever 834 and bar 833 and also rocks said lever in a direction clocln wise on Fig. 7 whereupon the bar 833 is moved downwardly over the paper and later takes a fresh grip upon the paper when the clamping lever is released by the cam on the next forward movement'of the carriage and moves downwardly under` the action of the-spring 839.

I prefer to use an inking ribbon of which the supporting and feeding :means is generally indicated by reference numeral 850, but this forms no part of the invention herein claimed. l

When a total is printed it is desirable to show some visual signal to indicate that the number printed is a total. rlhis is accomplished by shifting the carriage to the left when the total is printed, whereby the total is shown printed a `little into the right of the alinement of the listed column.

Means for accomplishing this result will now be described. l

As shown in Fig. 8, the lower edge of maaier the locating bar 824 is provided with a notch 880 in which engages the upper end of the vertical lever 881 pivoted interme- 'diately on the bracket 882 tixed on the printoted on a pin 885 in a. lug 888 on the base of the madhine. The forward end of said horizontal lever is pivotally connected to the rear end of the total shift lever 232.

When the total pin 236 engages in the groove 244, said pin is shifted to the right, and the upper end of the lever 882 is, therefore, shifted to the left, whereupon the locating bar is moved to the left on the pin 622 in the slot 625, thus causing the printin to take place a slight distance to the right of the column.

When by means of the lever 660 the carriage has been set to 'a non-printing position so that the items accumulated are not printed, it is still desirable that the totals themselves be printed. In order to accomplish this printing automatically, there is provided the automatic printing lock lever 887 (Fig. 8') pivotally mounted onthe bracket 888 fixed to the shaft 639, the upper end of which lever engages in a notch 890 the lower end engaging a transverse\pin 891 in the printing lock shaft 650. When the carriage is shifted to the left, the bar 624 is moved therewith and carries the upper end of the lever 887 to the left whereupon the lower part of said lever, said printing lock shaft and the cones 745 are moved to the right thus locking together the upper and lower printing levers 637 and 638 and effecting the printing.

From the foregoing, the operation of the printing carriage will be easily understood.

aper 1s inserted in the rear opening bctween the outer shields 767 and the paper rolls 748, and the paper rolls 748 are turned by means of the knob 431 until the part on which it is desired first to print are opposite the platen blocks 758.

The locking lever 6G() is set in locked or `unlocked position depending upon whether it is desired that the items be printed or not.

The machine is then started in operation as heretofore explained and the type is set and the accumulators accumulate. If the locking lever is set in locked position the cams 642 causel the printing levers and the carriage to reciprocate and the printing is effected.

When a total is taken the carriage is moved to the left just before the printing by means of the total signal lever 881 engaging in the notch 880 of the locating bar. lf the locking lever 660 has not been set in printing position, the automatic levers 887 also cause the cones 745 to lock the printing levers and print totals when the totals are set up and y presented by the type sectors.
