Serial No. 748,940.

This invention relates toautomatic tabulating machines having automatic total taking mechanism and controlled by analyzers or sensing mechanisms in turn controlled by perforations or designationsin record cards, though it is noted that in some respects the present invention is not limited to tabulating machines nor even to perforated-card-controlled machines.

Heretofore, I have invented several machines of this type having mechanisms for automatically initiating and taking totals and resuming operation at the ends of the successive groups of record cards. The present invention relates to improvements over these and similar machines.

In one type of machine I provided what are called spacing and total cards which are interposed between the respective groups to be totalled, these cards properly controlling the sequence of necessary operations for eflecting cortect total taking, the space card causing the required idle revolution of the adding machine beforetaking a total, the total card initiating the total taking operation. In large installations, the expense of making these special cards and loss of time in inserting them in the proper places is very great, and one object of the present invention is to do away with the use of such cards, and hence with the expense and loss of time.

When inserting these cards, sometimes the operator fails to insert the cards in the proper place, or fails to insert one or both at the end of some group, or fails to insert the separate spacing and total cards in the proper sequence. These failures cause errors and attendant confusion, delay and necessity of repetition of work, which of themselves are costly and may sometimes result in irreparable injury.

In another type of machine invented by me, the total taking is initiated bythe change in the location of the groups designating perforations between the respective groups. For operating this type of machine, the perforations designating the class to which each group of cards belongs must have the same arrangement and locationon the respective cards, which arrangement and location must be different from that of the cards of the preceding and succeeding groups. When the groups of cards pass through the designation change sensing portion of the analyzing mechanism, this mechanism senses the change at theend of each group and brings about the taking of the total.-

In this type of machine the class-designating perforations of each class group must be the same throughout the group and must be different from the adjacent words, it is not possible to spend upon this method of taking totals if the designating perforations of all the groups are the same,

as the machine could not sense the change from one group to the next; or ifthe designating perforations of any group were not groups. In other the same, aswhen the cards were mixed or contained cards of one or more classes, as then the totals would be taken at random throughout the group; or if the class designating perforations were omitted entirely, as when the classifying matter is written or printed, It is an object of the present invention to provide a machine which will automatically bring about the takin of a total, and subsequent resumption of ad ing on the next card group,- independently of the presence or absence or arrangement or location of any designating or classification perforations as distinguished from amount perforations. For example, in many instances the perforated record cards are of paper of different colors to distinguish the difierent departments in which they belong or the different items of business to which the relate. In such case, differently colored car groups could be placed in the magazine successively, for instance, brown, green, yellow, red, white or the like; and as each grou of a certain color of aper is fed through t e machine, a total of t at group will be taken automatically and the adding operation of the machine on the next group resumed. The only perforations required on the cards are the amount perforations for adding. It the total number of cards of a series of groups are to be printed only a single counting perforation would be. required for use with the machine shown herein, though the invention is not limi-ted in its broadest aspect to a machine that requires perforations for counting or even to mathematical operations.

Another object is to provide an analyzer disabler, operating without the use of a spacing card or without stopping the analyzer pin box, for disabling the analyzer to permit the required idle or spacing cycle before total taking as ex lained above.

Another 0 ject is to provide in an accounting or other machine of this type, a card feeling means in the feeding means itself, whereby operations controlled thereby may be initiated at an early instant, thus giving the various mechanisms more time to act than is the case where the feeler is in the analyzer.

Still other objects of the invention are to improve generally the simplicity and efiiciency of card control mechanisms and to provide apparatus of this kind which is durable, economical to manufacture, easy to operate and which will not easily get outof order.

Still other objects of the invention will appear as the description proceeds; and while herein details of the invention are described, various changes may be made without depart-- ing from the scope of the invention as claimed.

The inventive features for the accomplishment of these and other objects are shown herein in connection with a tabulating machine which includes an adding machine having a card analyzer provided with yieldable analyzer pins adapted for passing through perforations of the cards. A magazine for holding groups of the cards supplies them to apicker mechanism for feedln the cards from the magazine to the ana yzer. The magazine is constructed for permitting the passage of one card group and then preventmg the passage of the next group until the magazine is shifted. A. feeler feels the cards being fed and as soon as all of one group is fed, the feeler senses the absence of cards and thereupon actuates a shifting mechanism for shifting a retaining plate for holding down the analyzer pins and thus disabling the analyzer when no card is fed thereto to permit the adding machine to complete the addin raising of the analyzing pins would interfere with. A total initiating mechanism including a rock shaft and a clutch is also controlled b said feeler and actuates tripping means w ich causes the machine to take the total and clear the machine at the proper time after the completion of the adding operation. Said initiating mechanism also brings about the shifting of the magazine to ermit the feeding of the next group and t e resumption of the operation of the machine.

My improved automatic total taking mechanism is shown inconnection with an automatic accounting machine of the general type shown in my United States Patents Nos. 1,245,502 and 1,245,506 issued Nov. 6, 1917; and also the United States Patent No. 1,388,271 issued Aug. 23, 1921.

This accounting machine comprises an adding machine mounted on a frame 11 carrying a. card analyzer and feed means later to be described.

The analyzer comprises fixed upper and. lower spaced perforated analyzer plates 12 and 13 (Fig. 12) between which perforated cards are fed. A vertically reciprocatory pin box 14 carries yieldably projected analyzer pins 15 adapted to pass through the perforations 16 (Fig. 14) in the lower plate to engage the card 17 at points where no perforation exists in the card or to pass through perforations in the card and into the registering perforations 18 of the upper plate, where they engage and raise terminal pins 19 slidably disposed in said perforations '18 and in similar perforations in a plate 20. Said terminal pins in turn engage and raise extension rods 21 resting on the terminal pins for controlling the registering of numbers and the like in the adding machine 10.

The feeding mechanism Pairs of opposed feeding rolls 22, (Fig. 12) adjacent to the analyzer, feed cards into the analyzer from a feeding mechanism comprising a picker supporting frame 23 (Figs. 1, 2 and 5) adjacent to the said rolls and provided with guide channels 24 (Fig. 5) across the ends and a throat block 25 at'the discharge side. An elongated picker block 26 on said frame is rovided with a pair of end shoes 27 (Fig. 5 slidable in said guide channels 24. The picker block is continuously reciprocated by, means of a picker lever 28 Fig. 7) actuated from a cam 29 (Fig. 12) on t e main shaft 30 as described in'said patents.

A picker blade 31 secured on the rear of said block projects a short distance through a slot in a card supporting plate 32 mounted fast on the picker block and rovided with a rear extension 33 and a pair 0 forward extensions 34 (Fig. 5) forming therebetween a forward opening 35 for the rece tion of the throat block 25 as the picker bloc moves forward. A card positioning guide frame or container 38 (Fig. 3) mounted on said picker supporting frame is provided at its forward end with a horizontal slit 39 forming an elongated member 40 cooperating with the throat block 25 to form the card gate or throat 41 through which cards are projected by' the picker blade to the feed rollers 22.

The member 40 is adapted to be sprung to-- ward the throat block by an adjusting screw as shown.

The card magazine A magazine base 43 resting on said guide frame or container 38 is provided at one end with a boss 44 pivotally received on a bearing bushing 45 carried in a projection 46 of the frame 23. A bolt bracket 47 at the opposite end of said base is provided with a vertical bore 48 having an enlarged lower portion 49. A bolt 50 slidable in said bore is provided at the upper end with a manipulating wheel 52 and at the lower end with a collar 53 guiding th'e'bolt in the bore at the lower end. A spring 54 in said enlarged portion compressed between the shoulder formed by said enlarged portion and said collar presses the bolt into an opening 55 to hold the card. shaped opening 56 of said base in registration with the guide frame 38. A retaining'member 57 mounted on said frame is provided with an undercut groove in which may be engaged an arcuate projection 58 on said collar 53 to hold the bolt in locked position. When the bolt 48 is unlocked and raised the base 43 may be swung entirely clear of the guide frame 38, thus to give unobstructed access to the picker. A ear plate 60 rotatably disposed in anannu ar groove 61 of the magazine base and on bearing ribs 62 of said base is provided with an intramarginal crossshaped opening or card reservoir 63 (Figs. 2 and 3). The opposite ends of this opening are adapted to register with said card shaped opening 56 of the container 38 of the base when the gear plate is disposed at either of its two normal positions at right angles to each other. A retaining ring 64 fast on base 43 holds said gear plate in position and carries a stop pin 65 adapted to be engaged by stop plates 66 mounted fast on said gear plate 60 to stop said plate in the registering positions. Card end guides 68 mounted on said gear plate are formed with end and side walls 69 and 70 for engaging and positioning the cards 17 to holdthem in the crossedor staggered relation in which they are stacked, as shown in Fig. 4, before they are placed in the magazine. One corner 71 of one of each pair of end guides is bevelled to engage the cut-off corners 72 of the cards to prevent the misplacing of the cards in the end guides, so the cards cannot be fed backwards or upside down.

The lower cards of the lowest group, or all of the lowest group, if the group be small,

drop through the opening 56 into the guide frame 38, whereupon the lowest card rests on the supporting plate 32 to be engaged by the picker blade and fed through the card gate to the feed rollers and thence to the analyzer. The feeding action continues until all of the cards are fed from the lowest group, the cards of the group next above in the meantime resting on the base 43 and the ribs 62 thereof, which thus act as a preventin means to hold said group from the picker. Wfien the last card is fed from the lowest group, certain automatic actions, later to be described, are set up which causes the taking of the total of said lowest group and the shifting of the gear plate 60 and everything carried thereon through 90 to bring said next to the lowest group, which has now become the lowest group, into registration with the card shaped opening 56 and the guide frame 38, whereupon the feeding of cards is resumed. The gear plate 60 is slightly grooved to receive the ribs 62' to prevent cards getting between the gear plate and base when the gear plate is shifted.

If the card groups are small and of less height than the guide frame 38, the next to the lowest group will always be supported by the base 43 and thus carry the load of all the cards above and relieve the pressure on the lowest group and the picker. lhis is an important advantage of the present inven tion. With my former machine it was not possible to feed the cards properly when a large number of cards was placed in the magazine as the weight of these cards exerted too great a pressure on the picker, whereas with the present invention a hundred or more of these small groups can be placed in the magazine at once, while only the weight of the lowest group bears on the picker. This advantage permits a single operator to load one machine while other machines are working and thus attend several more machines than was possible with my former machine.

The suction card positions?" In my earliest machine, some difficulty was experienced in making the cards lie fiat on the picker and throat block for effecting positive and reliable feeding. To remedy thisit' has been customary to place a flat weight upon the cards, but even this fails to give perfect results every time, especially when only one or a few cards are in the magazine. I overcome this difficulty by suction'means which will now be described.

A suction pump (Fig. 1) mounted on the motor supporting frame 76 and driven by the belt 77 from the motor 7 8,0f the machine tends to create a vacuum in a suction pipe 79 (Fig. 6) extending from said pump to a suction orifice 80 (Fig. 7) through the throat block. A U-shaped pipe 81 extending to orifices 82 near the picker blade and ex- The card feelem or sensing mechanism The above mentioned automatic actions are brought about by the action of a card feeler 85 (Figs. 2, 3, 5, 7, 10 and 11) supported in a strap bracket 86 mounted on the base 23 at the rear face of the picker block to provide a vertical guideway for the thin feeler shank 87 (Fig. 10) disposed in said guideway with its edges in the direction of the path of the cards and provided at the rear edge with a recess 88. The upper end of the shank is provided with a flat head 89 for engagement. with the bottommost card. A fiat spring 90 (Fig. 3) mounted on the lower face of the picker supporting frame 23 engages the lower end of said shank and is just strong enough to raise the feeler when no card is resting thereon and weak enough to be depressed by the feeler when a single card rests thereon.

A pair of levers 93 (Fig. 5) disposed longitudinally to the picker block are intermediately fulcrumed, as at 94, on the lower face of said forward extensions 34 for movement in a horizontal plane and have their inner ends 95 disposed directly behind the shank 87 (Figs. 10 and 11), whereby when the feeler is depressed and said picker block is moved forward, said inner ends 95 will engage said shank and oscillate said levers. On the other hand, if said fceler is raised by said flat spring when no card is resting on the feeler, said inner ends 95 will engage in said recess 88 (Fig. 11) and said levers will not be oscillated.

When said levers are oscillated they project forwardly a pair of push rods 97 (Figs; 5 and 10) having their rear ends pivoted to the outer end of said levers 93 and provided intermediately with longitudinal slots 98 receiving retaining pins 99 mounted on said forwardextensions 34 for retaining and guiding the push rods forwardly.

A rock'shaft"100 (Figs. 9,12, 16 and 17) disposed transversely across the machine below the path of the cards and mounted in the side frames of the machine for rocking movement is rocked back and forth once during each cycle of operation for a reason which will presently be stated, by means of an oscillating lever 101 having its upper end fast on said rock shaft and its lower end forwardly turned to form an elbow portion 103 saaoae the oscillating lever 101 during the period of each, cycle when the analyzer pins 15 are in their lower positions.

The analyser dz'sabler Sleeves 110 (Figs. 9, 13, 14 and 16) loosely mounted on the rock shaft 100, for independent movement relative thereto carry fast thereon lever arms 111 (Fig.- 13) adapted to be pushed forward or clockwise by said push rods 97. against the action of springs 112. Lifting arms 115 (Figs. 13 andt16) also fast on said sleeves are each provided with a laterally turned flange 116 adapted whenever the arms 111 are not pushed forward or clockwise to engage and raise a downwardly projecting cam edge 117 (Fig. 16) at the rear end of a dog 118 pivoted at its forward end to the upper end of an upwardly and forwardly inclined arm 119 fast on the rock shaft. A. spring 120 yieldably holds the dog depressed.

The rods 97 are normally projected each time the picker feeds a card forwardly thus forcing the

arms

111 and 115 forwardly and permitting the dog to fall. When the picker moves back, the rods 97 and the

arms

111 and 115 are retracted by the springs 112, raising the dogs 118. Thus the dogs are lowered once for each adding cycle of the machine, and this lowering-takes place so that they are in their lowered positions at the time that the cam groove portion 109 is at the position of Fig. 12. I

An upper shaft 123 (Figs. 13, 14 and 18) mounted in said frame for oscillatory movement above said rock shaft and above the path of the cards carries downwardly projecting arms 124 provided with radial notches 125 each .adapted to receive a tooth 126 on its associated dog when the latter is raised thereby to rock said shaft 123 as the dog is rocked to the right. A short lever 128 fast on shaft 123 is pivoted to the end of a forwardly extending, shift bar 129 for shifting a retaining plate 130 disposed be tween said

analyzer plates

12 and 13 for supporting the pins 19 and provided at its forward edge with an upturned lip 131 (Figs. 8 and 12) provided with perforations received on horizontal pins 132 fast in the forward edge of the upper. analyzer plate 12 to prevent the retaining plate from sagging. The upwardly inclined rear edge portion 134 of said retaining plate helps guide the cards into the analyzer and carries a lug 135 rovided with an upturned internally threa ed projection 136 (Fig. 13) guided in a slot 137 and held in a lug 138 (Fig. 9) of the bar 129 by means of a screw 140 (Fig. 13) passing through said shift bar and received in said projection for holding the retaining plate fast with said shift bar.

When said shift bar 129 and retaining plate 130 and the notched lever 124 are in the osition shown in Figs. 13 and 14, the per orations of the retaining plate aline with the perforations of the analyzer plates; but when the last card of a group hasbeen analyzed and the feeler recess 88 (Fig. 11) rises to receive the ends 95 of the levers 93, said

arms

111 and 115 are not pushed forward as in Fig. 14, but remain under the dog 118 whereby said shift bar and retaining plate are pushed forward, as in Fig. 15, and the perforations 142 of the retaining plate move out ofregister with said terminal pins 19 and analyzer pins 15 and prevent the rising of the analyzer pins and the raising thereby of the terminal pins and the extension rods 21, thus to permit the adding machine to complete the carrying process of the adding cycle before 'takin the total. This permits the disabling of t e anal zer without the necessity of stopping the pin ox,

the latter being continuously reciprocated by means of the pin box cams 143 (Fig. 9) carried on the main shaft 30and engaging rollers carried on extensions 144 of the pin box as well known in my former machine.-

The chatch and total initiating A bracket 145 (Figs. 9 and 18) mounted on the frame of the machine a. distance below said rock shaft'100 carriesa short shaft 146 carrying fast thereon a toothed lever 147 (Fig. 18) provided at its upper end with gear teeth 148 meshing with teeth 149 of a down-' wardly projecting toothed sector 150 fast on upper shaft 123. The intermediate part of said toothed lever 147 is provided with. a large transverse clearance opening 151 receiving rock shaft 100, but outof contact with the rock shaft permitting the upright arrangement of the toothed lever as shown. An arm 155 fast on shaft 146 carries a pendant link 156 having its lower end pivoted to a cam lever 157 havi its rear end pivoted to a. bracket 158 on t e base 159 of the machine frame and yieldably raised by a compression spring 160. A total initiatin shaft 163 disposed across the lower part 0 the machine in bearing brackets 158 and 164 (Fig. 9) carries a cran 165 provided with a horizontal bore 166 receiving a clutch bolt 167 provided with a head 168 norma1ly en aged by said cam lever 157, which is slig tly forwardly inclined away from the crank, as shown in Fig. 19, for withdrawin the bolt from the crank and normally ho ding it withdrawn against the action of spring 169 compressed between a shoulder 170 of the crank and a collar 171 on the bolt. A sleeve 173 (Fig. 19) rotatably mounted on shaft 163 is rotated by means of reduction gears 174, 175 (see also Fig. 20), interposed between said sleeve and main shaft whereby the sleeve is rotated at half the speed of the main shaft. A disk 176 (Fig. 19), fast on said sleeve is provided with diametrically opposite lugs 177 adapted to be engaged by said bolt when said cam lever has released it, whereby said total shaft is rotated until said head 168 again comes into engagement with the cam lever and is withdrawn from said lug, thereby giving the total shaft only one complete rotation each time the upper shaft 123 is rocked as previously explained. A bearing sleeve 180 (Fig. 9') mounted in the machine frame carries a tripping shaft 181 in turn carrying a lever 182 (Fig. 20), provided at its free end with a roller 183 adapted to be engaged by a tripping cam 184 mounted on said total initiating shaft 163 after 180 rotation of the shaft. Said tripping shaft also carries a forwardly projecting arm 185 connected by an upwardly extending link 186 to a forwardly projecting tripping link 187 intermediately fulcrumed on the upper end of the active arm 188 of a bell crank lever 189 (Fig. 12) fulcrumed at its elbow part upon a bracket 190 on the machine frame and provided at its lower end with an anti-friction roller 191 engaging in a groove 192 of a total cam 193 carriedon said main shaft. A tripping lug 195 carried on the forward end of tripping link 187 is adapted to actuate a total shaft actuating. mechanism 196 when link 187 is tripped by the action of cam 184 and moved longitudinally by said bell crank lever thereby to set the adding machine for taking a total.

This actuating mechanism is well known as the one used on my former machine and includes a short fixed shaft 197 carried on the main frame and carrying loosely thereon an upwardly extending arm 198 carrying a lateral pin 199 engageableby said lug 195. The shaft 197 also loosely carries an active arm 200 fast with said arm 198 and connected by a link 201 to a lever 202 fast on the total shaft 203 of the adding machine, whereby when the link 187 is tripped into the position shown by the dot-dash lines in Fig. 12, and the lug 195 engages the pin 199, said total I shaft is rocked and the total taking mechanism of the adding machine is set in operation. In order to hold the total shaft rocked long enough for the total taking operation to be completed, the arm 205-, also fast with said

arms

198 and 200, is caught by a latch 206 fulcrumed on the bracket arm 207 fast on said fixed shaft. After the total operation iscom- 209. In Fig. 12'the total shaft 203 is Shown ssaose operated and latched, a condition brought about by the control of the cam 184 under the roller 183 and the operation of the lever 189 by the cam groove 192 of the cam 193 as it the initiating shaft 163 by

reduction gears

213 and 214 whereby shift cam 210 is rotated by shaft 163 one half of a rotation for each complete rotation of the shaft 163. A shift link or bar 215, provided with a longitudinal series of rack teeth 216, carries a slot 217 at one end received on said cam shaft 211 and a guide slot 218 at the other end received on a guide pin 219 fast on an extension 220 on said bracket 164. A roller 223 onsaid shift bar engages in said groove 212 for shifting said link from one limit to the other for each half rotation of the shift cam. A vertical counter shaft 224 mounted in said extension carries fast on its upper end a pinion 225 (Fig. 19) engaging said rack teeth 216 and on its lower end is provided with a gear 226 engaging a smaller gear 227 on the lower end of a spindle 228 having its lower end mounted "in said extension and its upper end mounted in said bearing bushing 45 (Fig. 3) on saidpicker frame 23. A drive pinion 230 (Fig. 2) loosely mounted on the upper end of spindle 228 engages the teeth 231 of the gear plate 60.

A collar 232 fast on the upper end of said .the inward movement of said members thereby to position said pinion relative to said spindle, said spring permitting yielding movement between said spindle and drive 'pinion thereby to prevent the breaking of any of'the gears should the magazine be accidentally held stationary.

It will thus be seen that each time the shaft I 163 is rotated, the cam 210 moves 180 and a the bar 215 moves from one limit to the other and rotates the pinion 225, the

gears

226 and 227, and the spindle 228, the pinion 230 and the gearplate 60, the teeth and diameters of said pinions, gears and gear plates being such masses that one complete movement of the bar 215 gives a quarter r0tation.to the gear plate and the parts carried thereon.

The operation The cards are separated and arranged in crossed or staggered relation as shown in Fig. 4. If the groups correspond to perforations onthe cards, this grouping is done on the sorting machine. If the grouping 1s according to colors not corresponding to any perforations of the cards, the groupmg is done by hand, the various colors having prevlously been placed. together. If perforated cards are grouped without regard to the perforations thereon, or if picture or printed cards or im'perforated cards of any k nd are grouped as for counting, the grouping w1ll take place as the various cards are selected depending upon the manner of selection under the given circumstances.

The cards having been grouped or stacked as shown in Fig. 4, a suitable number of groups are placed in the magazine, the beveled corners 71 of the magazine (Fig. 2)

. and the beveled corners 7 2 of the cards insuring that they are properly directed. The lowest group should preferably register with the card shaped opening 56. The height of the end guides 68 and the card guide 38 need not be limited to the heights, illustrated; and if the card groups are small, a large number of them may be placed in the magazine at once as hereinbefore fully explained.

Preferably the machine is started after the cards are in the magazine, since if not the machine will go through the action of taking and clearing zero totals, that is, taking a total with no number registered in the machine. If the lowest group is not in the card guide frame 38, the machine will take a zero total and shift the magazine 90 and drop the lowest group into the guide frame 38.

With the magazine loaded and with cards in the guide frame 38 and the machine started, the suction at the orifices and 82 positions the lowest card to the picker blade and on the throat block, depressing the feeler 85, so that when the picker moves forward to feed the card to the feed rolls 22. the recess 88 (Fig. 10) will be out of register with the .ends 95 of the levers 93 causing said levers to project forward the push rods 97 (Fig. 14) and push forwardthe

arms

111 and 115 to permit each dog 118 to drop down as shown in Fig. 14. The dog 118 is in its lowered position at the time the cam groove portion 109 and lever 101 are in the position shown in Fig. 12. When the arm 119 is rocked as the 'dog is out of engagement with the notched arm 124, the shaft 123 is not rocked, the retaining pla 130 is not shifted to the position of Fig. 15, the

sectors

150 and 147 are not rocked, the cam lever 157 is not lowered, the bolt 167 is not released and the total is not taken nor is the magazine shifted.

' From the feed rolls, the cards pass. between the

analyzer plates

12 and 13 and since, as explained, the retaining plate 130 is not shifted, the cards are analyzed in the ordinary way and pass on to the usual card receptacle (not shown).

The above analyzing or registering operation continues until all of the cards of a group have been fed from'the magazine.

T otaZ ta king Operation no card rests on the feeler, the feeler will rise (Fig. 11) undr the action of the spring (Fig. 3), the ends (Fig. 5) of the levers 93 (Fig. 11) will be received in the recess 88, the push rods 97 (Fig. 13) will not be pushed forward as the picker moves forward,

arms

111 and 115 will not move forward'and the dogs 118 will not be dropped down from theposition of Fig. 13 when the cam groove port-ion 109 reaches the position of. Fig. 12 and has moved the dogs to' the left into the position shown in Fig. 13.

When the cam groove portion 109 passes the position of Fig. 12, it rocks the lever 101 and arm 119 in a direction clockwise to-the position shown in Fig. 15, whereby the dog 118 moves the notched arm 124 to the position of Fig. 15, rocking the upper shaft 123 and shifting the plate 130 until the perforations 142 move out of register with the analyzer pins 15 to prevent the rising of the pins while the adding machine and pin box finish the cycle thus permitting the completion of the adding operation before the commencement of the total taking operation.

When the upper shaft 123 is thus rocked in this counter-clockwise direction, the sector 150 (Fig. 18) and associated parts cause the depression of the cam lever 157 and the release of the bolt 167 (Figs. 9 and 19) into engagement with one of the constantly revolving lugs 17 7, whereby the total initiating shaft 163 is given one complete rotation, bringing the bolt head 168 again into camming engagement with the cam lever 157 (see Fig. 19 and causing the withdrawal of the bolt rom the lug 177 to permit the shaft 163 to come to rest. As the sleeve 173 rotates with half the speed of the main shaft, it is necessary to have twolugs 177 in order that a lug be presented to the bolt 167 once during every cycle of the machine. I This single rotation of the initiating shaft will cause the tripping cam184; to move in a counter-clockwise direction toward the roller 183, but the cam will not reach the roller until after the bell crank 189 has been normally rocked while the lug 195 is in raised position. Thus during the first half of the rotation of the initiating shaft, the

total shaft-203 will not berocked, the total taking mechanism will not be set and the main shaft and the pin box, which make two cycles during the rotation of the initiating shaft will complete an idle cycle While the analyzer pins are being held down as above explained. This will give time for the completion of the adding operation, and

before the bell crank 189 is rocked again,

the cam 184 will have reached the roller 183 and caused the rocking of the tripping link 187 to the position of the dotted lines so that the rocking of the bell crank 189 by the cam groove 192 will cause the then lowered lug 195 to engage the pin 199 and the rocking This shifting of the shift bar and the conse quent rotation of the spindle 228 causes the rotation of magazine supporting gear plate 60 (Fig. 2) through 90, thus bringing the card group which was resting on the base 43 into registration with the card shaped opening 56 to permit said group, which has now become the lowest group, to rest upon the picker and depress the'feeler to prevent further rocking of the upper shaft 123 tFig. 14) until the analyzing and adding of the next group is complete, as previously described.

The above operations are repeated as long as cards are supplied to the magazine.

When groups of cards are to be counted, one column or digit of the card and the adding machine is reserved for this purpose, the index point 1 of this column of the card being perforated. The card groups are fed through the machine and the unit 1 is added by the machine each time; at the end of the group the total of these units is the number of cards in the group. In this way cards may be counted which contain thereon only printed or written matter except for the single perforated index point 1.
