The invention herein relates to a printing tabulator which is adapted to be actuated by. perforated cards, which in their passage through the machine operate elements for setting up type commensurate with. the designat ons on th card and actuate anaccumulatingv mechanlsm for accumulating thereinthe data recorded on the card perfor- L.

a'tions whereby the total accumulated data may be computed andthen printed by the printing elements of the machine.

The embodiment illustrated in said c0 1 pending application comprises a main frame, the card feeding mechanism the card analyzingmechanism, and an upper base 10 (Figf 1) on which the accumulating and printing mechanism l2.hereinafter to be described and the paper carriage 13 are mounted.

The cards to be analyzed are disposed in a receptaclev and. are. fed to the analyzing mechanism in which, as shown in said copendlng application. analyzing pins, which find perforations 1n the cards being analyzed,

tension pins, which in turn actuate registering stop 14; After the cards have been ana passupwzirdly therethrough and engage ex lyzed they are discharged into a suitable r receptacle.

The first step in the operation of the type setting tabulating mechanism, consists in the pushingup of the various stop pins 14. (Fig. 2) by'means of the extension pins. which are actuated by the various perforations in the cards as theypass 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 type setting and tabulating mechanism is given in said copending application.

The 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'cardsl Ea'chrow of registering stops 14 have a zero stop 16 associated' therewith, which is normally in zero stopping position and will remain so unless one of the regis tering stops 1 to 9 inclusive associ'ated therewith is actuated and therefore it is unnece's sary for aze'ro analyzing pin to actuate or cooperate with a; zero stop 16.

Herein: the part .of' the accounting machine to the left of Fig.2'wi11' be considered the forward part of the machine, while" that tothe right of Fi'gl 2'will be-con'sidered the rear of the accounting machinefi The registering steps 14 in the present instance are arranged-in a suitablenumber of rows having'ten'stop's' ina'ehrow, the stopsof each row corresponding to the integers!) to1- inclusive and; zero, the stop 9 being at the forward' end of the machine and the zero stop at the rear end thereof. The stops l4' corresponding to the integers 1 to 9'inclusiv'e are each composed of aflat body portion comprising ahead havingfor- '-Cwardly projectingportion 17 a cam face 18 facing'forward directly above said projec tion 17, a small rectangular shaped abut merit-'19 made on one side of the pin and adjacent itsu'pper end, and a lower restoringnotch 21'*on the rear edge thereof. The stops1 4 have their projections 17 normally resting on'an upp'er stop'plate 22 and extenddown 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 supported on the cheek plates 34.

ward from the extension 36 and a recess 38 herein. The zero stops 16 are normally disposed in raised position and whenever a stop 14 is actuated to the raised position,

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, which 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' an'dpivotally mounted in slots 67 at'the rear ends 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 7 0 which are' arranged to. slide within a recess38 formed in tlie rearedge of'the naught'stop 16.

Supported by the cheek plates 34 is a comb plate 71 the upper end of which is slotted to permit the lever 62 to extend therethrough and be guided thereby. A coil spring 71 is strained between the abutment 66 and the lower edge of the said plate 71 for the purpose of normally raising the naught-stops 16 into the position shown in Fig.3 2. Attention is called totlie fact that when one of the stops 14 is raised, the actu ation of the lever 62 by means of the coeperation of the slot 21, carried by thestop, with the plug 63, carried by the lever, will cause the link 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 been heretofore 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 passed from the machine, means is provided for returning the pins 14 to their normal lower position for actuation by the next incoming card. This means for returning the stop pinsto their normal position is de scribed in detail in said copending applica tion.

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'entir'e type setting and calcula ting'mechanis'm. This lever 72 is provided with a pin 74 upon which is rotatably mounted a roller 75 which is arranged to roll within a cam slot 76 of a cam 77.

There is provided and described in said copending 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 68 carried thereby will engage the slots 21 of the stop pins 14 and pull them downward to their normal lowered position. The naught stop pins 16 are arranged, as shown in Fig. 7, tonormally retain or hold back reciprocating rack bars, which during their reciprocation actuate type setting.ele-. ments. As heretofore described, the raising of a stop pin will lower the naught stop-so that upon the actuation of a stop pin, 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 reciprocation members have actuated the type setting elements and upon being stopped by the raised stop pins will hold the type setting elements in a position to set type corresponding with the numberof the'raised stop pins. A detaileddescription of the reciprocating rack bars and their connection and cooperation with the naught stops,-stop pins andtype setting elements will now be described.

- The reciprocating rack bars each comprise a relatively thin bar shaped body portion 82 which is provided with a longitudinal slot 83 that isadapted to slide along a transverse bar 84, secured to the cheek plates 34. Atransverse bar 85 is also provided which serves as a support for the forward end of the bar 82. The bar 85 is rigidly fastened to the cheek plates 34. A second relatively thin bar shaped member 86 is pivoted 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 bar 89 which is reciprocated by means hereinafter to be described, and during its reciprocation will move both the bar 82 and the bar 86 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 shaft182 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 vertically extending arm 92 which is made integral with the inner end of the bar 82.

The free end of the bar 86 is provided with an offset portion 93 which is adapted to extend through a slot-94 in the upper edge of the bar 82 so that the extreme end 95 of the bar 86 may engage the bar 82 on its opposite'side. Due to this arrangement the two bars 82 and 86 are always held together and as the bar 86 swings on its pivot 87' the end 95 of the bar 86 will engage and slide up and down against the vertically extending arm 92 carried by the bar 82. A. horizontally extending pin 96 is carried by oneside face of the bar 82 which is adjacent to thebar 86 and pivotally mounted upon which is a bell crank lever 97 (Fig. 10), 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 v86.. The other end of the lever. 97 is;provided-wi th.a"lug 100 havinga cam front face 101 and a right angular notcn 102, in its rear edge,"the horizontal :wall of which is extendedout at right angles to the lever 97 forming a rest 103 (Fig. 2). The upper edge of the bar 82 is provided with an upstanding abutment 104 having avertical front wall or inwardly. turned shoulder 105. and an inclined or .cam rear wall 106, the purpose of which inclined wall willbe hereinafter set forth. The bottom edg'ebf the bar 82 is provided with an abutment 104similar but smaller than the abutment 104 carried by its upper edge. This abutment 104. is provided with a vertical front wall. 10.5 directly beneath and in thesame planewith the vertical wall 105 of the abutment 104. The abutment 104 is also provided with an inclined or cam rear wall 106 the purpose of which will be hereinafter set forth. y, r The bar 89 which as heretobefore described, is for the purposefof reciprocating the bars 82 and 86 is itself reciprocated in the following manner, reference especiallybeing made to Fig- 1. I I

The bar 89 which is rectangular in cross section is rigidly connected at each end to a slidel07, which is-reciprocatable between rollers 108 forming guideways thereforQ A slot 109 is made in each cheek plate 84 which receive a roller 110 revolubly mounted on the shaft 111 secured to the rear end of the said slides 107. The front end of the slides 107 are provided with horizontally extending pins 112, which are reciprocatably mounted in slots 113 formed in the upper ends of levers 114, the lower portion of which are triangularly shaped, one corner being pivoted to stud shafts 115 carried by each cheek plate 34.. The other. corner of the triangular shaped leveis 114 carries a roller which is arranged to roll within a suitable cam groove in a cam carried on the shaft 7 4.

Returning now to the reciprocating bars 82, the top edge of the forward portionof the said bars 82 are provided with gear teeth 119 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 which segments have an are shaped rear edge pro- .vided with gear teeth 123 which will hereioo its

ment by means of the pin 9.8 carried by'the after be described. The front edge ofthe' q turned portions in engagement with said notches and openings respectively; Q'The plates 128 are secured to the segment by means of bolts 129. Reading from the uppe'r edge of the typecarrying portion of the segment, the type carried thereby read in sequence, the first type being z'ero,- the next 1, the next 2, etc., the last type onfthe segment being numbered 9. A

A description of the operation 'of the' stop pins, the reciprocating rackba'i's and. the oscillating type segments will new be given. In the position shown in Fig. 2 'a'llofthe' stop pins 14 are down and all of the naught stops 16 are in raised position. Whenthe stop ins 14 are in their initialraised position t e vertical walls 105 of the abutment 104 fit withinthe notches 38 in the; upper end of the naught stops and consequently hold the bars 82 and their associated bars 86 in their extreme rearward position, and

also retainall of the type segments in'a position to print ciphers. Although each spring 91 is exerting tension to lift the bar 86 nevertheless this bar is held to the limit of its downward movement dueto the fact that the rest 108 carried by one end of the'bell crank lever 97 will rest on top of the naught stop 16 (Fig. 7 which holds the said bell crank 97 at the limit .of its downward movemember 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 lowered simultaneously, as has been heretobefore explained. The downward movement of the naught stop 16 frees the 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 front side of the reciprocatingbar 89. Attention is called to the fact that 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 of the abutment 104. As soon as the notch 88 engages the reciprocating bar 89, the saidbar is locked between it and said vertical wall so that when the said bar 89 is reciprocated bymeans'of the lever 114 and its associated retreat parts, heretofore desdr'ibed,*the bar's 822ii1d 86 will also be moved forward. Sim1 1'lta neous with the forward movement'of the bar 86 the bell crank 97 is moved-dawn; As the bar 89 is reciproca'ted bythe *lever' 114, Ithe said bars 82 and 86will,be carriedwith it until the cam face 101 of the bell'crank errgages the rectangular =abu'tnient19 of the stop pin 14 which hasbeenraise'df This'cont a'ct lifts the bell crank 97, lowersjthe rod 8. against the te'nsion *of' the' spring 91 which in its downwardmovemeflt-freleases "the re-' ci-proc'atin bar 89. A'sf'so'on' as'g the '=bell crank 97 as been raised-fire vertical wall 105' of the abutment 104wi11 engage the rearend of the r ais'e'd stfip' i)if1 14 and pre vent the bar 82 moving fu fitlilz Sh e the reciprocating bar 89' is released as the bar 82 1s stopped, the bar 9 win continue its forward movement altheugh ltm:ba s2 and the: lever '86 have this is for the p rpeseof;ireeih g the bars 82 and 86 from thereciprbatingmembr 89'1ifs'they' engage thesto pins initheir' forward position and there 31* permitting theihai to carryall of th'e'fhja-rs 86 forvvartl which have not been freed therefrom in the manner here tofore described; Due to tlie'i 'ackt th ll9, as'the bar-"82 is moved forward, the type segment-1 22 is oscillated through-the mediumfofithe gear whe l 12o as her'etofore described? Afte'r all of the t pe' 'segmeuts liavebeen set by the 'stop ins in position--'to -'print data transferred'there'to from thetards, means is provided for locking and aimin the type segments sof'tha't they not move during the printing operation. {lh'is "locking and alining" means will 'howbe'briefly described. The extreme upper'end of thele'v'er 72is provided with a knife shaped "transversely extending arm 1.30 slidably mounted within a slot 131, within the cheekplates -'=Both the slot 131 and the knife'sha'ped member 130 which is herein termed 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. I 3

The locking of the printing segments and the releasing of the stops l l, is brought about simultaneously so; that the f'recipro'cating members may be free to be movedback to their original position after printing without engaging any stop pins whatever except the naught stops 16 as will be hereinafter more fully described. p

A mechanism is herein provided for preventing all of the ciphers to the left of the digit last set up by the stop pin from'being printed. Or in other words, a mechanism is provided for retracting all ofthe segments out of print-ingposition which have been left against the naught stops asthe released bars 82 start on their forward movement.

BEST AVAiLfld-ELE Relatively thin levers 132 are provided which have on their upper edges an abutment 133=pr0vided with a front cam wall 134 and a rear cam wall 135. 'The said rear cam wall is adapted to engage a cam wall 136 formed on thebottom ed'ge'of the reciprocatable bar 82 when the rack bars are retracted beyond zero printing position. The levers 132 are pivotally mounted upon a transverse shaft 137 which 'is 'reciprocat'ably mounted within slots 138 made in the cheek plates 34.

Meansi's provided for reciProcatingthe :which extends horizontally ,to the right of thelever 149 a suflicient distance to engage the adjacent bar 1320f the next lower order. A spring7157'isstrained; between a bar 152 fastened between theche'ek plates 34and a downwardly extending ear'159 made integral with. the'lower, edge of the bar 149. This spring is for the purpose of'normally holding the levers 132 and149 in such a position that thefrear cam wall 135 will engage the cam face 136 of ,the rack bar when the rack bar isretract ed beyond zero-printing position.

The operation'bf this'mechanism will now ,hedescribedg As the various stop pins 14 are elevated, and the associa'ted stop pins 16 are lowered, as ,has, been heretofore described the bars '82 arestarted on their forward stroke. "As they move forwardly the cam face 136 on the bottom edge of the rack bar 82 will strike the cam face .133 of the lever 132 and force it downwardly in the position shown in Fig. 2. The downward movement of the lever 132 will elevate the lever 149 which, through the medium of the horizontally extending lipj156 fastened theret'o,will engage the adjacent lever 132 to the right thereof and force it down. As these levers 132 are forced down they will clear the bottom edge of the levers 82. After all of the bars 82, which have been controlled by the stops 14, have started on their forward movement and have forced down all of the levers 132 associated to the right thereof, the bellcrank 139'is moved in a clockwisedirection by meansof theYroller 145, cam groove'146, and its other intermediate associated elements. This movement of the bell crank 139 will reciprocate all of the bars 132 but those which have already been depressed by the forward movement of the bars 82 will slide beneath the said bars 82 and upon a rod 160 mounted between the cheek plates 34, engaging a longitudinal slot 161 made in the inner end of the bar 1132. However, those bars 132, which have'not been depressed eitherby a movement of the bar 82 or by a lip 1-56 carried by the adjacent bar 149, will still be in their upward position-as mentioned above, in which the cam face 135 lies adjacent to the cam'face 136 of the reciprocatable bar 82.- As a consequence, when these lastmentionedlevers 132 are moved by the bell crank 139 a longitudinal slot 162 made-in the inner end of the 1ever133'will receive the bar'160 and 'preventthe 1ever 132 from being depressed.

As the bars 132 move farther under the action of the ball crank 39, the cam face- 135. will engage the cam face 136 andlfor'ce'fit backwardly. The cam groove146 is ofjsuch contour that the bellcrank'139will move the bars 82' back one space, so that the type segments associated therewith will occupy 'a' position as shown in Fig. 1, in which} the naught type are below the printing position. As a consequence, when thebars 82 have finished their forward movement and are set up for printing, all of-the typeseginents to the left of any type segment which is'controlled by a stop pin 14 will be'kicked back by the mechanism above described s o-"tha't they will be in a non-print position.

p to "this point the general operation of the mechanisms'thus far described, is as follows: hen any of the stop pins 14 corresponding to the perforations "in thefcards fed' through the machine, are raisedgthe naught stops in that-row'are simultaneously lowered which will permit the members 82 tomove forward. The forward movement ofthe bars 82 rocks the lever 132 in an anticlockwise direction, and allof the levers 132 of a lower order will also be rocked through the instrumentality of the lips 156, but all of the bars 82, of an order higher than the rack bar of the highest order that is permitted by the removal of the naught stop and the setting of the pin 14 to 'be'moved forwardly will be kicked back one space so that the type sectors are oscillated down out of printing position. The bars 82, which have been moved forward come to rest'the reciprocating bar 89 is freed and moves forward to the limit of its stroke. When all'of the type sectors are in position to print. the detent mechanism is operated, which slides the detent; 130 into the gear teeth 123 of the type segments and locks them against movement. Simultaneously.with theoperation' of the detent mechanism, the release mechanism releases the stop. pins 14 and permits them to be drawndown into their original position by means of the bar 62 which at the sametime raises the naught stops 16. The

paper carriage 13 is then, as will beexplained, moved up into engagement with the type on the type segments, and the printing operation takes place. The printing carriage is then retracted, and at the same time means is provided forlowering ,the bars 86 soas to raise the bell cranks 97 sothat when the-bars reach the limit of the rear-ward lstroke the rest 103 will be in position 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- (Fig. 2) which is arranged above the upper edge of the bars; ,86 being rigidly carried by the upper ends of slide levers 164 arranged gadj acent the inner face of each cheek 131M63 which during their downward movement slide the bar 163 in slots 165 madein the said cheek plates. The slots 165. are of a length sutlicient topermit the bar 163 to movedownin contactwith the upper .edge'of the-bars 86 and force them downward. The lower ends of the leversjl64; are provided with pins 166 which p oject r gh s ts- 7-i the ch e p at 34: and 35, which slots-are of-a length equal to the slots 165. The levers 16%.areireciprocated up and down by means of levers 168 arranged-adjacent the inner .faceof the cheek plates 3t and have bifurcated rear ends 169 whichstraddle the pins-166.1 The levers 168 are pivotedat 170 to each cheek plate and are oscillated by suitable connecting mechanism driven from a cam on the shaft 74.

As has been before described after the printing operation takes place the bar 163 is lowered so as to come in contact with-the upper edges of the bars 86 and force them thereof from the cam face 136 formed on the lower edges of the rack bars 82 and permit the rack bars to move forward until the abutments 104 carried thereby, come into engagement with the notch 38 of the naught stop 16.

The means for causing the forward move ment of the bars'which have been released; from the kick back mechanism, comprises levers 181 pivoted to a bar 182 carriedby the cheek plates 3 1, the upper end 183 of which is adapted to come in contact with pins 184i carried by rack bars 82, and force them forward by means of a spring 185 which is strained between the lower end 01 the levers 181 and a rod 186 carried by the cheek plates 3 1. The forward movementof the upper .ends of the levers 181 is limited by means of a horizontally disposed comb plate 188. Attention is called to the fact that all .013 the operati ns her t fore d scribed take place during the forward movement of the bars 82 and therefore the movementof the said bars in a forward direction may be termedthe printing stroke.

The accumulating elements of the ma chine are arranged to be operated during the rearward movement of the bars 82, and a description of this mechanism willnow be given.

The accumulating mechanism comprises a reciprocating carriage having spacedvertieallyarranged cheek plates 189 which are arranged within andadjacent to the cheek plates 34trespectively as is shown in Fig. 3.

The rear end of the cheek plates 189 is provided with longitudinal slots 205 which receive a releasing guide rod 206 rigidly carried by the cheek plates 34.

lWeans is 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 (Fig. .1) which have their upper ends respectively pivoted to the shaft 192. The lower ends of the levers are pivoted to stud shafts 211 on the upper. part of levers 215. The lower parts of the levers 215 extend inwardly toward each other and are provided with vertically extending relatively shaped plates 219 (Figs. 1 and 6) pinned together at their upper and lower edges by .means of pins,221.. The said plates-219 are rectangular whichare collars 227 which abut against the ends of the camf'shaft 225. The collar 227 is provided with an'a'nnular groove228 adapted to're'ceive the bifurcatedfe'ndi23l of a lever 232which is pivotally' mounted at 233 to the frame work as' is showniinfFig2.

A coilspring-248strained between the end of the lever 241 and the upper edge of the lever 232 provides means for normally hold ing said end in an upward position to be enga ed by the collar 2 12.. j

lieturningnow to the levers 215, which as stated'are for the purpose of reciprocating the'accu mulating carriage, thesel levers are pivotally mounted upon a transverse shaft 250 which is mounted in the cheek plates 34.

Between the said levers-207 and pivotally mounted on th'e shaft 250 are contactingends 251 of two separate levers 253 and 254:

respectively each of which has an opening receiving the cam shaft 225. The outer ends of the levers 253 carry rollers 260 and 261 of which one 260 is shown engaging a cam groove 262, which, during the revolution of the cam shaft 74; transmits a rocking motion to the said lever 253 which through the medium of thelevers 213 and 207 reciprocate's theaccumulating carriage. lVhen the "will be operated for taking totals.

strength'that the levers 207 and 213are for all practical purposes a single lever. f

When the cam shaft 225 is 'slidjby the lever 232"to one limitof movement, the

lever 25 1 is lockedto the levers 213 and the accumulator c' arriage'is rocked for accumulating'item s. However, when the cam shaft 225 ismoved to its otherlimitof movement,

the other lever 253 is locked to the lever 213 and the carriage is reciprocated for taking totals. The cam'grooves 262 being differently designed so' that this is accomplished. Th arrangement and operation of the cam shaft 225 and its cooperating parts are described in detail in said co-pending application.

In Fig. 2, the'position of the parts is such accumulator carriage is reciprocated for accumulating; the printing operationhas been completed and the parts are set for the free return of the rack bars 82. Before the bars 82 return rearwardly, however, the accumulating carriage will be moved forwardly until the accumulator wheels 197 have been brought in contact with the gear teeth 123 of the type segments. The rearward movement of the bars 82 will then rotate the accumulating gear wheels 197 and the type segments. en the rack bars 82 have reached the limit of their rearward movement, the lever 207 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 en- .gagement with a transverse bar 272 which is carried by the cheek plates 34s and holds the said accumulating gear wheels against accidental shifting.

Thisjreciprocation of the accumulating carriage backward and forward and the engagement 'and disengagement of the accumulating gear wheels with the gear teeth of the type-segments takes place as the bars 82 are 'at rest. However, when any of the accumulating gear wheels have made a c0mplete revolution the inclined wall 202 (Fig. 3) of the abutment 200 carried by the said gear wheel has been brought into engagement withthe inclined wall 273 made on the lower endof an L shaped settable lever 27 5, the said lever is rocked upwardly on its pivot 276 against the action of a coil spring 274; strained between the lever 275 and a transverse rod 276 carried between the cheek plates 189. This spring normally holds the lever 275 in a horizontal positionas is shown in Fig. 2. the upward movement of the lever being limited by a transverse rod 277 mounted between the cheek plates 189. In its horizontal position, the lever 275 holds a vertically extending lever or pendant link 278 to the limit of its upward movement, the upper edge of the lever 275 engaging a lip 279 carried by the side of -the lever 278, which movement is limited by the rod 277' mounted in a longitudinal slot 280 in the end of the lever 278, and holds the said lever 278 in its said upward position against the tension of a coil spring 280' strained between thefsaid leverand a transverse rod 281 carried between the cheek plates 189. A horizontally disposed comb plate 281' carried between the cheek plates 189 forms guide ways for the vertical extending levers- 278. Pivotedto the lower end of the lever 278 at the point 282 is a carrying bar or lever 283, guided in a vertically disposed guide combplate 284. The other end of the lever 283 is pivotally connected to the lower vend of a carrying lever or actuator 285 which .is provided with an enlar ed slot 286 receiving the transverse shaft 27 The up per 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, carried between thecheek plates 34. A coil spring 290 strained 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 slidably mounted in a vertically disposed 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 plates 34 and carries at its side edges rollers 296 which are adapted to roll in longitudinal slots 297 (Fig. 1) in the cheek plates 34.

The means for reciprocating the cam plate 295 backward and forward comprises levers 298 pivoted to the cam plate at the point 299, and carry on their lower edges rack teeth 300 which mesh with a pinion 301, revolubly mounted upon a shaft 302 slidably mounted in a longitudinal slot 303 in the cheek plates 34. Rollers 304 prevent the upward movement of said levers 298 and keep the rack teeth in engagement with the pinion 301. The pinion 301 is also in mesh with stationary rack bars 305 fastened to the outer face of the cheek plates 34.

This means comprises a bell crank detent lever 320 (Fig.3) pivoted upon a transverse shaft 321 carried by the cheek plates 169. Horizontally disposed comb plates 322 guide these levers during their movement. A coil spring 324 strained between the upper end of the lever 320 and a transverse shaft4325 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. When 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 shaft 206 and upon doing so will move the ,upper end of the lever rearwardly against the tension of the spring 328 releasing the vertically extending portion 326 of the lever 275 from the notch 327 and permit the said lever 275 to occupy its horizontal position under the action of the spring 27 A description of the operation of the carry over mechanism which has just been above described will now be given.

It is of course to'be understood that due to the fact that the abutmentsFZOO arecarried by the left hand fa ce of'each accumulative gear wheel. the set back mechanism heretofore described oft-he 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 accumulative gear wheel of the next higher order.

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

I 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. The lowering of-the stop pins will permit the reciprocating bars 82 associated therewith, to be moved forwardly. The forward movementofjhe,bars 82 will depress the leased are moving forwardly, these'last men tioned 'le'vers'l32 willbe reciprocfated rearwardly by means of the 'bell eranks l39 levers 1&3 and other elements associated therewith, which in their rearward movement will force back the bars 82 with which they are associated, and oscillate thetype 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 abutnients 104: carried on theirflower 'edgesfcomefl in contact with the various elevated stop 14: at which time they come to a the rack bars 82 have come to rest',i'jthe segments associated therewith have been (53% cillated upwardly a distance sufiicient to. set the type thereon in consonance with the number of the stop pin 14. When al l of the type segments have been oscillatedinto proper position the detent 130' drawn -down into engagement with the gear 123 on the type segments and alines and locks them so that they cannot be moved during the print operation. Simultaneous with the operation of the detent, the levers 62 and 1 I;

163 are actuated, the former causing the drawing down to the set stop pins :14 and ele rating 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 type segment and an impression made on the paper carried thereby. The rack bars .82 are now ready for their rearward movement, but previous thereto the reciprocating accumulating carriage has been moved forwardly so that the a cumulating gear wheels are brought into engagement with the teeth 123 of the-type segments. The locking detent for the type segments is withdrawn and the reciprocating bars are 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 the type printed. When the bars 82 have completed their rearward motion, the reciprocating accumulating carriage is 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 reciprocation bars 82, and the above operation continues. \VVh en any ofthe accumulative gear wheels have made a. complete revolution,.during which time the bars 82 associated therewith have moved rearwardly 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. 1

The above operation continues as the cards pass through the machine and the items thereon arev printed by the type sectors and accumulated. on the accumulator wheels until either a total card is fed to the X machineor until it is desired to take the total of the data accumulatedby operating a total key--manually. A description of this total taking mechanism will now be given.

All of the actions heretofore described have taken lace when thatvone of the levers 253, which might term the accumulating lever, is locked by meansof the reciprocating'cam shaft to the levers 215. When the total is to be taken the key 240 is lifted either manually or a push rod A controlled by the perforated cards, as is describedin my copending application, Serial No. 80,973, filed Feb. 28,1916. The reciprocating plunger 238 is released, which will spring intothe cam groove as stated and upon engaging therewith will rock the lever 232 about its pivot and reciprocate the cam shaft 255, which will unlock the accumulating lever 254 and lock the total taking lever 253, whereupon the locking of the lever 208 with the other lever 253 which I may term the total taking lever will cause the said lever to reciprocate the accumulating carriage forwardly until the accumlator wheels are brought into contact with the type segments.

At the same time that the cam shaft 255 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. This means is described in detail in said co-pending ap plication 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 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 edges of the vertically extending portion of the bar 275 (Fig. 8). 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 ear 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 outwardmovement, means is provided for releasing the said bar from engagement with the notches 88 formed in the bar-86-so thatthe 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 35?) come in contact as is shown in Fig. 26, the lever 350 is forced downwardly, which will force the bars 86 also downwardly through the medium of an outwardly turned lip 354 formed on the-outer end of the lever 350. The forcing down of the bars 86 as before described, will release the transverse reciprocating bar 89 and permit it to move downwardly to the-limit of its stroke. When all of the type segments have been set up in the manner heretofore described. the detent 130 is brought into contactwith the gear teeth of the type segments and locks the said segments in printing position. The reciprocating printing carriage 13 is then moved up into engagement with-the type and an impression made on the paper carried thereby. This impression gives the total of the data accumulated by the accumulative gear wheels. After the printing operation is completed the detent 130 is lifted. The bars 82 then move rearwardly during which motion the reciprocating plunger 238 is forced back into its locked position as shown in Fig 3, and the lever 232 has been rocked about its pivot 233 and thereby reciprocated the cam shaft225 backto accumulating-position. 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 with the digits to accumulating, so that it cannot run forward cationj,"

This holds the'rece'ss' 88 and the shoulder formed thereby out of reach of the'drive bar 89, whereby the latter'may continue to reciprocate without moving the bars 82 and 86. 4

The printing carriage, designated generally by reference numeral 13 (Fig. 1) 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 tabulator.

The 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 printing carriage is carried on these L shaped brackets and is reciprocated therewith by means of bell-cranks 610 pivoted on a shaft 611 and provided with a roller engaging in a groove ona suitable cam carried onthe cam shaft 74.
