Claims.

This invention relates to a tens carrying mechanism and is a division of our application Serial No. 412,346, filed September 25, 1941.

The present invention is embodied in a machine of the general type disclosed in Letters Patent of the United States Nos. 1,619,796; 1,761,542; and 1,916,535, issued, respectively, March 1, 1927; June 3, 1930; and July 4, 1933, to Bernis M. Shipley; No. 2,141,332, issued December 27, 1938, to Charles H. Arnold; and No. 2,176,561, issued October 17, 1939, to Everett H. Placke.

The present invention is directed to a tens transfer mechanism adapted to a machine which includes four totalizer lines, each line consisting of a maximum of ten sets of interspersed totalizer wheels.

The principal object of the invention is to provide a novel tens transfer mechanism which is particularly adapted to a machine including interspersed totalizers.

Another object of the invention is the provision of improved transfer mechanism for transferring tens digits from lower denominations to higher denominations.

Another object of the invention is to provide novel means to shift'the totalizers laterally, for the purpose of transferring from lower to higher denomiational orders, without disturbing the previous selection of any totalizers under con trol of a selecting differential mechanism.

A specific object of the invention is to provide a tens transfer mechanism wherein the tens transfer elements are adjacent the amount entering actuators for interspersed totalizers; means for laterally shifting the row of interspersed totalizers for selecting a totalizer for actuation; and other means to shift the selected totalizer line laterally into alinement with the tens transfer segments after the amount has been entered, preparatory to receiving the tens transfer entries.

, With these and incidental objects in view, the invention includes certain novel features of construction and combinations of parts, the essential elements of which are set forth in appended claims and a preferred form or embodiment of which is hereinafter described with reference to the drawings which accompany and form a part of this specification.

GENERAL DESCRIPTION The keyboard of the machine embodying the instant invention comprises a plurality of rows of amount keys which in adding operations control the positioning of corresponding amount differential mechanisms, said differential mechanisms in turn being arranged to transmit the values of the depressed amount keys to the printing mechanism and to the wheels of the selected totalizer. In sub-total or total recording operations, the amount differential mechanisms, which include an amount actuator for each denominational order, are positioned by the ling the lateral shifting of the corresponding totalizer frameworks to aline the various sets of. totali'zer wheels with the amount actuators. The

four rows of transaction keys likewise control the lowest order. After the selected totalizer wheels are engaged with the transfer segments, said segments are released to the driving action of their springs, to cause the tripped segments to advance the wheels of the next higher order one digit,'to 'eifect a tens transfer. v v

The selected set of 'totalizer wheels remains in alinernent with the transfer segments at the end of the machine operation and are shifted back into alinement with the amount actuators at the beginning'o-f the succeeding operation, at which time all the previously tripped transfer segments positioning of four corresponding add selecting,

disks, which, in cooperation with their respective feeler mechanisms, control the radial shifting movement of the framework for the corresponding totalizer lines to cause the selected set of totalizer wheels on the selected totalizergline to be engaged with and disengaged from the amount actuators.

The amount differential mechanisms are driven by a main. cam shaft, which in adding operations makes one revolution and in sub-total recording or reading operationsand in total recording or resetting operations makes two such revolutions. Adding operations, which require one revolution of the main cam shaft, are commonlyreferred to as one-cycle operations, and sub-total and total recording operations, which require two revolutionsof the cam shaft, are commonlyreferred to as two-cycle operations.

In adding operations, initial movement of the differential mechanisms, under influence of the cam shaft, causes said mechanisms to be positioned under control of the depressed amount keys, and, during thispositioning, the framework of the selected totalizer line is shifted laterally,

' under influence of the depressed transaction keys,

to aline the selected set of totalizer wheels thereon with the amount actuators. After the selected set of totalizer wheels has been alined with the amount actuators, the corresponding feeler mechanism, in cooperation with the corresponding selecting disk, which has previously been positioned .under influence of the depressed transaction key,

causes the totalizer engaging mechanism to' be connected to the shiftable' framework for the selected totalizer line. Operation of the'totalizer engaging mechanism causes the selected set of totalizer wheels to be engaged with the amount actuators after said actuators have been positioned by the amount keys, as explained above,

' and return movement of said actuators'under influence of the main cam shaft, rotates the selected totalizer wheels in accordance with the values of said depressed amount keys to add in said wheels the amount set up on the keyboard.

A novel tens transfer mechanism, which functions in adding operations, is provided for transferring tens digits from lower to higher denominations. In adding operations, when the wheels of the selected totalizer pass from 9 to while being rotated in an additive direction b the amount actuators, a long tooth on said wheels trips the transfer mechanism for the next higher order. After the amount actuators have completed their return movement, the'framework for the selected totalizer line receives an auxiliary lateral shifting movement to move the selected set of totali'zer wheelsout of alinement with the amount actuators and into alinem'ent with a series of transfer segments which are located adjacent to the corresponding amount actuators, there being one such transfer segment in each denominational order "of each of the four totalizer lines except the are restored to .un'tripped position.

DETAILED DESCRIPTION Amount Difierentz'als The amount, keys 56 (Fig. 1) control the positioning of corresponding amount differential or actuator mechanisms, and, inasmuch as this differential mechanism i substantially duplicated in each denominational order, it is believed that a description of the mechanism of one such denomination'al order, as shown in Fig. 1, will be sufflcient for the purpose 'c-fthis specification.

The amount'keys M (Fig. l) of the denominational row here'shown, which is representative of all the rowsof amount keys, are mounted in a framework I0?! supported rods Iill and 'I II] in turn supported by the main framework of the machine; Depression of any one of the amount keys 54 rocks a zero stop pawl I82 counter-clockwise out of the path of a projection N3 of an amount actuator Hi4 free. on ashaft I journaled in the main frames 59, and moves the lower end of said depressed key into the path of said projection I63. When no amount, key 55 is depressed, the zero stop pawl IiiZ, under influence of a spring Iil9, is retained in'the path of the projection I63 and breaks the latch for this amount bank in zero position, as will be explained later.

The'actuator' I84 (Fig. 1) has therein an angular camming slot III, through which extends astud H2 in alatch II3 pivoted on a stud IM carried by a latch arm II5 free on the shaft I195. The stud I12 also extends through an angular camming slot H6, which'isla-companion slot to theislot II, said slot .I I6 being in a differential balanceplate II'I free on the shaft W5. A footshapedextensio'nyof the latch II3 has thereon a shoulder H3, which, in cooperation with a, similar shoulder on a .latch'drivingsegment I I9 free on the shaft I05, forms a driving connection between. said segment and the latch arm H5. A

,link' I20 operativelyconnect's the driving segment IIQto' an operating'le'v'er I2! pivoted on a stud I22 in a partitioniplate I23 for thisparticular amount bank, there being such a partition plate for each amount bank.

A boring in a downward extension'of the lever I2I freely'engagesa rod 124, opposite ends of which are secured in similar arms I25 (only'the left-hand arm b'eing shown here), said arms being pivoted on studs (not shown) similar to and 'known in the art, 'operatively connects the main 2,380,450 cam shaft I30, to the operating motor, said motor being arranged, to drive the shaft I30 one clockwise revolution in adding operations and two such revolutions in reading and resetting operations. Revolution of the main cam shaft I30, by means of the cams I28 and I29, imparts an invariable oscillating movement to the arms I25, the lever .I2I, and the latch-operating segment I I9, first clockwise and then counter-clockwise.

Initial movement clockwise of the segment I I9, by means of the shoulder thereon in cooperation with the shoulder II8 on the latch II3, carries said latch and the latch arm II clockwise in unison therewith. The latch I I3, by means of the stud I I2 in cooperation with the slots I II and I I6,

carries the actuator I04 and the balance plate II1 clockwise in unison therewith. In this case, a spring I61 and the downward inertia of the balance plate II1 causes the slot H6, in cooperation with the stud I I2, to retain the latch in engagement with the segment H9 and thereby overcomes any tendency of the slot III in the actuator I04 to cam said latch II3 out of engagement with the shoulder on the operating segment H9. The actuator I04 moves in unison with the segment II9 until the projection I03 engages the lower end of the stem of the depressed key 54, which obstructs, further clockwise movement of said actuator I04. Stopping of the actuator I04 causes the cam slot III, in cooperation with the stud II2, to cam the latch II3 counter-clockwise "to disengage the shoulder II8 from the segment I I9 and simultaneously to engage an arcuate surface on the top of said latch with the corresponding one of a series of alining notches I32 in a curved alining bar I33 secured to the partition plate I23 for this particular amount bank, said plate I23 being supported by the shaft I05 and the rods I34, I35, and I35, in turn supported by the main framework of the machine. {is the segment II9 continues its clockwise movement without interruption, an arcuate surface thereon passes in the path of the foot-shaped extension of the latch II3 to lock said latch, the arm H5, and the actuator I04 in set positions.

The actuator I04 has, on the periphery thereof, a plurality of gear teeth I31 arranged to cooperate with the different sets of totalizer wheels I38 to I4I inclusive, carried respectively by the Nos. 1, 2, 3, and 4 totalizer lines.

In adding operations, after the actuator I04 has been positioned, as explained above, the selected totalizer line is shifted radially to engage the corresponding one of the selected set of totalizer wheels thereon with the teeth I31 of the actuator I04. After the corresponding one of the selected set of totalizer wheels has ben engaged with the actuator I04, return movement counterclockwise of the operating segment I I9 moves the arcuate surface on said segment beyond the footshaped extension of the latch I I3 and simultaneously causes a stud I42 carried thereby to engage a raised surface on the latch arm II5 to rearm II5 causes the alining notch I32, in cooperation with the arcuate surface on the latch I I3 and the spring I61, to reengage the shoulder II8 on said latch I I3 with the corresponding shoulder on the operating segment I I 9. During its return movement counter-clockwise, the actuator I 04 ,rotates the wheel I38 of the selected totalizer in -3 an additive direction, in accordance with the value of the depressed amount key 54, to add said value into said wheel.

An aliner I43 (Fig. 2), in cooperation with the teeth I31, retains the actuator I04 in set position in all types of operations. Obviously the aliner I43 is disengaged while the actuator I04 is being positioned.

The differential movement of the actuator I04 is transmitted to the indicator mechanism by the well-known minimum movement mechanism including beam I45, link I41, and segment I48. The link I41 also transmits the differential setting movement of the actuator to type carriers I58, through segment I50, link I52, segment I53, and the Well-known internal-external gear mechanism I55, the latter being fully disclosed in United States Patent No. 1,693,279, issued November 27, 1928, to Walter J. Kreider.

Transfer mechanism A tens transfer mechanism is provided for transferring tens digits from lower to higher denominations. The transfer mechanism for each totalizer line comprises a transfer segment and its associated tripping mechanism for each denominational order, except the lowest order, and, when a totalizer wheel passes from 9 to 0 While traveling in an additive direction, the long tooth thereon trips the transfer mechanism for the next higher order. The transfer segments are located adjacent to and parallel with the corresponding amount actuators; therefore, after the amount actuators have completed their return movements, to enter the value of the amount set up on the amount keys in the selected totalizer wheels, it is necessary to shift the selected totalizer line or lines a slight distance laterally to aline said wheels with the corresponding transfer segments. Immediately thereafter, the previously tripped transfer segments function to add one in the totalizer wheels of the nextv higher orders.

During the auxiliary shifting of the totalizer 'line to move the selected totalizer wheels into alinement with the transfer segments, said line; is partially disengaged to insure that said wheels; do not stumble on the transfer segments and to insure that adjacent wheels do not stumble on the teeth of the actuators. The selected totalizer wheels remain in engagement with the transfer segments at the end of machine operation and are disengaged therefrom immediately at the beginning of the succeeding operation, after which the totalizer line is restored laterally to aline the wheels thereof with the amount actuators.

Inasmuch as the transfer mechanisms for the different denominational orders and for the different lines of totalizers are identical, it is believed that a description of the transfer mechanism for the denominational order of the No. l totalizer line shown in Fig, 1, will suffice.

The transfer mechanism for the denominational order of the No. 1 totalizer line, shown in Fig. 1, comprises a transfer segment I10 (Fig. 2) pivoted on a stud I1I in a plate I12 supported by the rods I34, I35, and I36. Aspring I13 urges the segment I10 counter-clockwise to normally maintain a camming surface I14 thereon in engagement with a stud I15 in a transfer operating arm I16 free on a stud I11 in the plate I12. A spring I10 urges the arm I16 clockwise to normally maintain a bent-over ear I19 thereon in contact with a retaining tooth I on a trans fer trip yoke 'I8I- free on a stud I82 inthe plate I12 for the order here shown.

When the selected No. 1 totalizerwheel I30, in the next lower order to. the order shown in Figs. 1 and 2, passesthroughzero, along tooth I83 thereon engages a bent-over extension I84 on the yoke I8I and rocks. said yoke counter.- clockwise to disengage the tooth I80 from the ear-I19 to release the arm I16 to the action of thespring I18, which rockssaid .arm a. slight distance clockwiseuntil the ear I10 passes-beyond the tooth I80 and untila, dependingfinger I85 of said arm I10 contacts .a stud I80, which at this time is in the position here shown in dot-anddash lines The stud I80 is secured in a restoring disk I81 fast on the shaft I05, there being such a disk for each denominational order, with the exception of the lowest order. Also fast on the shaft I (Fig.2). is a crank I 00 carrying a stud I89 embraced by a. slot. in acam lever I90 free on a stationary stud I9I. Angularly disposed arms of the lever'I90 carry, respectively, rollers I92 and I93, which cooperate respectively with the peripheries of companion plate cams I90 and I95 secured on the main cam shaft IS. The timing of the cams I04 and I95 is such that initial movment of said cams, through the lever I90,- rocks the disk I81 clockwise, causing the-stud I00, in cooperation with thedepending finger I85, to restore the operating arm I16 counter-clockwise against the action of its spring H0 until the ear I19 passes beyond the tooth I80. Continued rotation of the cams I94 and I95 returns the disk I81 and the stud I86 a slight distance counter-clockwise to permit the ear I19 to engage the tooth I80 to latch the transfer mechanism in untripped position, and to position thestud I80 a slight distance away from the finger I85, as shown in dotand-dash lines in 2. Restoring movement counter-clockwise of the operating arm I16 causes the stud I15, in cooperation with the camming surface 115, to restore the tripping segment I10 clockwise against the action of the spring I13.- I

It should be noted that the restoring of the transfer mechanism takes place during initial movement of the amount actuators I04 and prior to the time the selected totalizerwheels-are engaged therewith. Return movement of the amount actuator for the next lower order wheel I38 (Fig. 2) rotates said wheel in an additive or clockwise direction; causing the long tooth I83 thereon to engage the extension I84 to trip, the yoke I01, in the mannerexplained above. -After the amount actuator has completed its return movement, the-transfer shift is impartedto the No. 1 totalizer line to move the wheels I of the selected totalizer into alinement with the transfersegments' I10, and immediately thereafter the cams I94 and I95 return the disk I01 counter-clockwise to the position shown here. The operating arm I10 moves clockwise in unison with the disk I81, causing the stud I15, in cooperation with the camming surface I14, to permit the spring I13 to rock the segment counterclockwise to advance the totalizer wheel I38, for the order here shown, one digit to effect a tens transfer.

The mechanism for imparting auxiliary or transfer shifting movement to the totalizer line will be explained later herein in connection with the totalizer selecting and engaging mechanism.

In reading and resetting operations, the wheel I38 (Fig. 2) is reversely rotated by the amount actuator I04 until the long tooth" I83 thereon comes into contact with the extension I81 to locate said wheel in zero position and t position the actuator and the recording mechanism in accordance therewith.

Transactionlc'eys and differential mechanism therefor The differential mechanism for each. of the four rowsoftransactionkeys is simi1ar:in every respect to the amountdifferential mechanism shown in Fig, 1 and explained above, and, as the transaction differentiahmechanism is substantially duplicated for each row of transaction keys,-. itris believed thata description of ,the differential mechanism. for the first row of transaction keys, shown in Fig. 3, will suflicefor all.

The transaction keys 55 for the first transaction bank are mountedxina key frame I supported by the rods IOI and III) in, exactly the same manner as the amount key banks. Depression of. any one of the transaction keys 55.ro.cks a zero stop pawl I99 counter-clockwise out of the path of a projection 200 ,of an actuator .20I free on the shaft I05, said actuator 20I being operatively connected to abalance plate 202 by means of angular slot in said actuator and said plate, in cooperation with. a stud in a latch203 pivotally mounted on a latcharm 204 free on the shaft I05. The latch 203 cooperatesswith a shoulder on a differential operating segment 205 free on the shaft I05 and connected by a'link 200 to an operating lever 201 .free on a stationary stud 298. The cam lever- 201 carries rollers 29 and 2E0, which cooperate, respectively, with the peripheries of companion plate cams 2 II and 2I2 secured on the main camshaft130. The cams 2H and H2 function torock theactuator 20I first clockwise and back to normal position during each revolution of said main shaft I30. The parts of the transacticndifierential described briefiy above are similar to and function exactly like similarparts of the amount actuator shown in Fig. l and described earlier herein.

Initial movement clockwise of the lever 201,

through the segment 205 and the latch 203, carries the actuator ZOI clockwise in unison therewith until the projection 200 contacts the stem of the depressed transaction key, which positions said actuator according to the value of said depressed transaction key. This disengages the latch 203 from the segment 205 in exactly the same manner as described for the amount bank, thus permitting said s'egmentand the lever 201 to complete their initial movements clockwise independently thereof. When the lever 201nears the terminus of its initial movement clockwise, a roller 213 carried thereby engages anarcuate surface on a beam 254 pivoted on thearm 204, to position said beam in accordance with the depressed transaction key. -The rearward end of the beam 214 is bifurcated to embrace a stud 22-5 in a 11m; 21s, the upper end of which link is pivotally connected to a gear sector 2l1 secured to one, of a plurality of nested tubes 2 I8' freeon the. shaft M9. The. lower end of the link '21s is pivotally connected to asegment 2I9 free on the shaft IEI, and connected by a sleeve 220 to a crank 221. The crank 22I '(Figsl d and 4) is connected by a link 222 to a segment 223 free on the shaft I05, said segment meshing with a gear 220 secured on a short shaft 225 journaled in plates 225 and 221 supported by the rods I34, 135,8.1101136 (Fig. 1).

Also secured on the, shaft,225-(Figs. 3 a'nd 4) is a disk carrying three studs 220*(onlytv'vo right-hand end of the No. 1

being shown), which freely engage corresponding borings in theleft-hand face of a'drum cam 230 free on the shaft 225. The cam 230 has a helical cam groove 23I, which cooperates with a roller 232 secured in a slide 233 shiftably mounted on the top surface of a yoke 234 by means of studs in said slide in cooperation with horizontal slots in said yoke, said roller 232 arranged to extend through one of said horizontal slots. The yoke 234 is free on the shaft 225, but is held against rotary movement by a roller 235 carried thereby, in cooperation with a horizontal slot in a bracket 236 secured to the plate 226, and by means of a vertical slot in the left-hand extension thereof, in cooperation with a stud 231 in the Plate 221. An annular groov 238 (Fig. 4) in a reduced portion of the drum cam 230, in cooperation with a slotted bracket 239 secured to the yoke 234, maintains said drum cam and said yoke in fixed lateral relationship to each other.

An upturned portion of the-slide 233 (Figs. 3 and 4) has therein a slot 240, which engages an annular groove MI in a hub portion of a totalizer frame side member 242, said hub portion having therein a boring which freely engages a shaft 243 which is arranged to be shifted radially in a manner presently to be described, to engage the selected set of totalizer wheels with the amount actuators. The side member 242 supports the totalizer line or rod, while a similar side member 258 (Fig. 1), also slidably mounted on the shaft 243, supports the left-hand end of said No. 1 totalizer line, said side members, together with the No. 1 totalizer line and the shaft'243, forming a shiftable framework for engaging and disengaging the No. .1 totalizer wheels with and from the amount actu ators. The lower ends of the side members 242 and 258 have therein similar slots which engage similar tooth-shaped blocks 244I (Fig. 4) carried by the plates I23, said blocks being the shape of and in alinement with the teeth in the actu ators I04 (Fig.1).

The roller 235 (Figs. 4 and 6) extends into a cam slot 244 in one of four camming extensions on a transfer. shift cam 245 free on the shaft I05. An extension 246 of the cam otally connected thereto the upper end of a link 241 having a stud 249 in the lower end, which normally engages a slot in an'arm 248 fixedly connected, by a hub free on a stud 250 in the plate 226, to a cam arm 25I. The cam arm 25I carries rollers 252 and 253, which cooperate respectively with the peripheries of companion plate cams 254 and 255 secured on the main cam shaft I30.

The timing of the cams 254 and 255 is such that the arms 25I and 248 and the cam 245 (Figs 5 and 6) are shifted clockwise prior to initial movement of the amount actuators I04. Clockwise movement of the cam 245, by means of the slot 244 in cooperation the yoke 234 toward the left, as viewed in Fig. 4, which movement is transmitted by the bracket 239 to the drum cam 230 andthence by the cam groove 23I and the roller 232 to the slide 233. This shifts the member 242and the No. 1 totalizer framework a slight distance toward the left to move the selectedtotalizer wheels out of alinement with the transfer segments I and into alinement with the amount actuators I 04 (see also Figs. 1 and 2).

After the selected set of wheels on the No. 1

totalizerhas been shifted out of alinement with 245 has pivwith the roller 235, shifts the transfer segments, as explained above, the roller 2I3 (Fig. 3) engages the beam 2I4 to position said beam in accordance with the depressed transaction key, and this positioning is transmitted by the link 2I6 to the sector 2I1, the segment 2I9, and the crank 22I. The crank 22I, by means of the link 222, rocks the gear segment 223 from zero position, as here shown, in a clockwise direction to a position corresponding to the depressed transaction key. Clockwise movement of the segment 223 (Fig. 3) rotates the gear 224, the shaft 225, and the drum cam 230 counterclockwise, causing the cam groove 23I (Fig. 4) in said drum cam, in cooperation with the roller 232, to shift the slide 233 and the totalizer framework, comprising the members 242 and 258 and the No. 1 totalizer line, toward the left, as here viewed, to aline the set of totalizer wheels I38 corresponding to the depressed transaction key 55 with the amount actuators I04.

In adding operations, after the selected set of totalizer wheels has thus been alined with the amount actuators, radial shifting movement is imparted to the shaft 243 (Figs; 1 and 3), as will be presenting explained, to engage the selected totalizer wheels with the amount actuators I04, after said actuators have been positioned under influence of the depressed amount keys. Return movement counter-clockwise of said actuators rotates said wheels in an additive direction to enter the amount therein, and, after said actuators have completed their return movements, the totalizer wheels are slightly disengaged from the actuators, and the cams 254 and '255 (Fig. 6) function to shift the No. 1 totalizer a slight distance to the right to move the selected set of wheels thereon into alinement-with the transfer segments I10; After this, the Norl'totalizer line is returned to full engaged position and the tripp d transfer segments I10 (Fig. 2) then function, under influence of their cams I94 and I95, to effect the transfer of tens digits from lower to higher, denominations, in the manner explained earlier herein.

At the endof a machine operation, the selected set of totalizer wheels remains in alinement with the transfer segments I10 and is returnedinto alinement with the amount actuators I04 at the beginning of the succeeding operation.

Totalieer engaging mechanism In machines of the type to which the present invention is shown applied, a selecting means un der control of the transaction banks of keys is provided for selecting the line of totalizers to be engaged with the-amount differentials I04 for receiving entries. Since this selecting means forms no part of the present invention, it is not disclosed herein. thereof, reference may be had to the parent case, referred to hereinbefore. For the purpose of understanding the present invention, it is only 'nec-' essary to know that, when a totalizer on a selected totalizer line is to be engaged with the amount actuators, a stud 3I0 (Fig. 5) is rocked into engagement with a notch 348. at the proper time, and when said notch is alined with the stud 3 I 0.-

The stud 3I0 is carried on a link 3 pivotally connected to the end of a lever 3 I2 free on a stud 3I3 in the frame 5|. A link 3| 4 pivotally connects the lever 3| 2 to the end of a lever 3I5 secured on the shaft 243, said lever carrying a roller 3 I 6, which engages a camming slot 3I1 in a totalizer engaging plate 3 I8 secured to the frame For a complete disclosure 5!.

Operation The novel tens transfer" mechanismoperates as followsz The transaction keys 55 control the selection of-a 't'otalizer line by well k'now'n inea'n's described in the parent'application and in ithe paten'ts referred'to herein: After a'line has beenselected, a utotalizer on the line is selected by the depressed control key 55, which, through the differential mechanism controlled thereby," rotates segment 223 and drum" cam 23!] to shift the desired-totalizer into alinement with the amount actuators I04. Thereafter, the engaging mechanism shown in Fig! 5' engages the' s'elected totalizer- -with the actuators I04, sothatamourits set-on the keyboard can" be entered in the totalizer.

When a; totalizer wheelpass'esfirom etc 0, the longtooth I83 thereon'trips'yoke "IN to release arm H5 which at this time 'isarrested by stud l B3','-wh'ich' stud at thistime is 'in the dot-and dash position? (Fig. 2'). After the ainount has been entereddnto thetotalize'rg the-totaliz'er is partially disengaged-from the racks lll4 'by cams 338-339 I (Fig.5) and the "mechanis'rn 'op'erated thereby; Thereafter, 'the-totalizer line-is shifted by earn 254-255 (Fig. 6)"-t'o' aline the totalizer. int0= which the'amountswereentered by the amount differential, with the transfer segments I10. "After the totaliz'er wheel'sareengagedWith the segments l-ll'hthe-stud's' ltfi are withdrawnto their original position by cams ISM-495 (Fig. 2) to release the tripped arms I16, which in turn releases the associated transfer segments I to enter the tens carries in the proper totalizer elements. Thereafter, the machine comes to rest.

Near the beginning of the next machine oper ation, the cams 338339 disengage the totalizer from the actuators, and the cams I94--l 95 thereafter restore the trippedtransfer segments I!!! by moving the member I81 and the studs I86 clockwise slightly beyond the dot-and-dash position shown in Fig. 2. This movement of the studs I86 past such position rocks the members I16 counter-clockwise until the trip members |8l again latch the members H6 in the positions shown. During such counter-clockwise movement of the members H6, the studs I thereon move the transfer segments I10 back to their normal positions.
