The present invention relates to cash registers and accounting machines, and concerns more particularly the totalizer selecting mechanism and the tens carrying mechanism.
It is old and well known in the art to select for simultaneous operation a plurality of totalizers each of which is arranged on a diiferent shaft. However, it is often desirableto. select for simultaneous operation a plurality of totalisers all arrangedon a common shaft. 1 To this end the present invention provides novel means for selecting a variable number of totalizers arranged on a common shaft, together with special tens carrying mechanism for performing the proper transfer from lower to higher denominational order wheels; I
It is, therefore, a primary object of this invention to provide novel means for selecting for oporation a plurality of totalizers all arranged on a common shaft.
Another object is to provide means for selecting a variable number of totalizers a common shaft.
A further object is to provide means for causing a plurality of totaiizer-s, arranged in interall arranged on spersed fashion on a common shaft, to be actuated by a single differentially movable actuator. An additional object is to provide means Whereby a variable number of totalizers, all arranged on a common shaft, may be selectively coupled to a single diiferentially movable, actuator.
Another object is to provide means for transferring a total from one of a plurality of totalizers mounted on a common shaft to any other one of totalizers.
'A still further object is to provide novel tens carrying mechanism for transferring from a lower denominational wheel to a higher denominational wheel.

DETAILED DESCRIPTION The machine herein, illustrated is provided 50 with a plurality of totalizers similar to the totalizers shown and described in United States Letters Patent to Lehmann et al., 2,108,896. Each totalizer comprises adding wheels H! (Fig. '7) arrangedininterspersed order on acommon shaft or 55 support. For instance, the adding wheels: of the same denomination for each totalizer are grouped together, there being a group of units adding wheels, a group of tens adding wheels, and so on. Each denominational group of adding wheels I0 is freely mounted on a hub Ii of a setting wheel I2 corresponding to that particular group of wheels. The setting wheels I2, in turn, are freely mounted on a sleeve I4 which is nested on a sleeve 2I shiftably mounted on a rod (Figs; '7 and 10). Each setting wheel I2 is associated with and adapted to be actuated by an individual differentially movable actuator I3. During each operation of the machine, the actuators I3 are rocked first clockwise and then counterclockwise, under control of banks of amount keys, as clearly shown in the above Patent No. 2,108,896, and thus rotate the setting wheels I2 extents commensurate with the value of the amount keys depressed.
The ends of the hubs I I contact each other, and
- the wheels I2 are mounted in hubs in the upper ends of totalizer carriers I 6 secured to a shaft I9. The latter is connected, in any desired manner, with the machine drive and is rocked thereby at different times (Fig. 18) to either engage the setting wheels I2 with the actuators I3 in the performance of an adding operation or engage the adding wheels ID with toothed sectors II5 and I2! (Figs. 9, 10, 11 and 13) to transfer one from a wheel ID of lower order to a wheel Ill of next higher order. When the machine is at rest, the shaft I9 is positioned to hold the totalizer wheels in an ineffective position, as shown in Fig. 10. The adding wheels I0 are prevented from being accidentally moved out of their respective positions during the above mentioned rocking movements of the shaft I9 by means of springpressed retaining pawls I35 mounted on a rod I36 supported by the totalizer carriers I6. The time of the engaging and disengagingmovements of the totalizer wheels is shown in the time chart, Fig. 18.
' Means is provided for selectively coupling one or more adding wheels Ill of each denominational group to the setting wheel I2 associated therewith, so that said selecting adding wheels IE! will be actuated the same extent as imparted to the wheel I2 by differentially movable actuator I3. This means will now be described.
, Each sleeve I4 (Fig. 7) comprises a plurality of individual sections all located end to end on the sleeve 2I carried by the shaft 20. Each sectional sleeve I4 is associated with a different denominational group of adding wheels II). The various sections of the sleeve I4 are free to rotate independently of each other about the sleeve 2I but are compelled, by means of -a plate I? secured at one end of the shaft 20 and a pin [8 (Fig. 5) extending through the opposite end of said shaft, to take part in any shifting movement imparted to the shaft 20. When participating in such shifting movement, the various sections comprising the sleeve I4 move in unison as one single body. The sleeve 2I is provided with an elongated slot 22 through which extends the pin I8, thus permitting the shaft 20 and the sleeve 2I to be shifted relatively to each other.
Associated with each denominational group of adding wheels I0 is a coupling member I5 (Figs. 7 and 10) rotatably mounted in an annular groove formed in the section of the sleeve I 4 corresponding to that particular group of adding wheels. The member I5 protrudes through a transverse slot formed in the hub II of the setting wheel I2.
The member I5 is shiftable with the sleeve I4 to engage internal teeth 24, of any one of the adding Wheels Ill associated therewith, from the ninth down to the second totalizer, to thereby couple said adding wheel to the common setting Wheel I2 therefor. The member I5, when in its normal extreme left hand position (Fig. 7), .enters an internal groove 23 of its respective totalizer carrier I6 whereby the member I5 is prevented from being shifted unintentionally. However, before the sleeve I4 is rotated for any operation, the member I5 may be shifted to the right to select a totalizer for actuation. When the shaft 20 and the sleeve I I are shifted to the right by means to be hereinafter described, the members I5 are simultaneously moved into engagement with the internal teeth 24 of the adding wheels ill of one of the totalizers, so that the adding wheels of the totalizer selected are coupled to the associated setting wheels I2.
Likewise, associated with each denominational group of adding wheels Ii) is another coupling member 25 rotatably mounted in an annular groove formed in the sleeve 2|. The member 25 also protrudes through the transverse slot in the hub H of the setting wheel I2. Like the member i5, the member 25 is shiftable with the sleeve 2I to engage internal teeth24 of any one of the adding wheels II] associated therewith, from the first totalizer to and including the ninth totalizer, to thereby couple. said adding wheel It to the common setting wheel I2 corresponding thereto. The member 25, when in its normal extreme right hand position (Fig. '7), engages internal teeth of its respective setting wheel I2 and is thus prevented from engaging the internal teeth 24 of any of the adding wheels Iil. When in this position the member 25 will rotate idly with the setting wheel I2. Thus, when the sleeve 2| is shifted to the left by means to be hereinafter described, the members 25 are simultaneously moved into engagement with the internal teeth 24 of the add ing wheels ID of one of the totalizers, so that the adding wheels of the totalizer selected are coupled to their associated setting wheels I2.
Thus, from the above it will be seen that when the actuators I3 actuate their respective setting wheels I2, the members I5 and 25 associated with each of said setting wheels are, by means of the hub I I, caused to be rotated with their respective setting wheel I2. The lateral shifting of the members I5 and the members 25 relatively to each other determines which totalizers are to be coupled to the setting wheels I2 during an operation of the machine.
The means for shifting the members I5 in the manner above described will now be explained. The right hand end of the sleeve I4 (Fig. 5) is adapted to be rocked within a slot 26 (Fig. 3) of a plate 2'! but is incapable of being shifted transversely in saidslot. The plate 27, in turn, is shiftably mounted on two rods 28 and 29 and has a guide roller 36 engaging a cam groove 3Ia. formed in a drum 3I. While the sleeve I4 is not shiftable in the slot 26 it is shiftable with the plate 2'1, as will be more fully described hereinafter. The drum 3I is secured to a shaft 32 (Figs. 3 and 5) suitably journaled in side frames of the machine. Fast to the right hand end of the shaft 32 is a gear 33 meshing with a setting segment 34 secured to a shaft 35 which has fast thereto an arm I42 (Figs. 6 and 12). The free end of the arm I42 is notched to contact a stud I43 of an arm I44, secured to the hub of a gear I45. A spring 4|, attached to segment 34, mainhereinaf described. With t e g ar M5 in its home non, as shown in Fig. 12, the arm I44,
segment fa l and drum 3| are so positioned that the cam groove Zita formed in the latter will position the plate 2? so that theshait 2t, sleeve I4 and members It": are in their extreme left hand positions, with the members I5 rendered ineffective iecause at this time they are in engagement with the internal gear 23 (Fig. 7) of their respective tctalizer carriers I6.
As shown in the time chart, Fig. 18, after the amount diiierential actuators I3 are adjusted,- the arm 5M, through the gear I45, is given an oscillatory movement, first in a clockwise directicn (Fig. 12) until the pin M3 thereof assumes a position designated by @435, and then, after the actuators i3 returned to their home positions, the arm M4 is returned in a counter-clockwise direction to its home position. When the arm t i l is rocked clockwise as just described, a springs! (Fig. 3) tends to rock the segment 36 in a like direction but is prevented from doing so by a pin t ereon contacting the lower end of a slot formed in a setting segment 38 freely mounted on the shaft 35. The segment 38 serves to adjust the tens carrying mechanism which will be hereinafter described. A spring 39 normally causes the segment 38 to contact a pin ila of an arm 4% (Fi 6) 'oined b means of i J v a sleeve to a gear Mi! connected to an intermittent oscillatory drive of the well-known type. When the machine is at rest, the pin 36 coacts with the lower end of the slot 37 in the segment (Fig. 3).
During an operation of the machine after the amount differentials have been adjusted, the arm til is rocked clockwise in substantially the same man-n the arm i-M until the pin 4m assumes the position designated by 40a (Fig. 3), from which position it is not returned to its home position until at the end of the operation. During the clockwise movement of the arm 4?"), the segment under the action of the spring 35), is This lik moved in a clockwise direction.
l clockwise direction to follow the arm M4- du g the latters clockwise movement. this occurs, the segment 34, meshing with the gear rotates the shaft 32 and drum 3| counterclockwise (Fig. 3). Due to the shape of the cam groove the drum 3! will at this time shift plate 27!, shaft 26 and sleeve M to the right an hus engage the members I5 with the internal M or the adding wheels Iii. When this is dished, the adding wheels of the selected tctalizer are coupled to their respective setting wheels iii. The means for controlling the selection the different totalizers will be hereinafter described.
After the amounts have been added into the car, the arm I44 is rocked counter-clockwise ome position (Fig. 12) and in so doing ccacts with the arm M2 to return the the gear 33, drum 3!, plate 2?, sleeve iait i153 and members it to their home positions. Since the arm All is not rocked counterclockwise to its home position until later, i. e.,
at the end of the operation, the segment 331'smains stationary for awhile, the slot 31 permitting the segment 34 to return counter-clockwise to its home position.
The means for shifting the members 25 in the manner hereinbeiore described will now be explained. The right-hand end of the sleeve 2| (Figs. 4 and 5) projects through a slot formed in a plate 112 shiitably mounted on the rods 28 and 25. The sleeve 2| is rc-ckable within the slot the plate i2 but is shiftable only with the plate 42. it which engages a cam groove Ma. formed in a drum Mi rotatably mounted on a sleeve 44' loose on. the shaft 32. v
Etigidly mounted in the; hub of the drum 4-4 is a stud I56 (Fig. 5) having pivoted-thereon a beveled pinion Hill. The pinion I5] meshes with pair of beveled gears I52 and IE3. The gear 552 is fast to a gear I54 secured to the left end of a sleeve 5% loose on the hub of the drum 44, while the gear I53 is secured to the left end of the sleeve M. The gear I54 meshes with a gear I550, which, in turn, meshes with a toothed segment i552: loosely mounted on a sleeve I55 on the shaft 35. The segment I55a, through the gears I55?) and i550, both secured to a shaft 45', constantly connected to a toothed segment I56 of totalizerselecting lever I51 (Fig. 14) on the shaft 35.
The beveled gear IE3 is connected, by means of the sleeve 44 (Fig. 5), to a gear 45 constantly meshing with a setting segment 46 (Fig. 4) pivoted on the shaft 35. The segment 46 is connected by means of the sleeve I55 to an arm I46. A s ring 5?! connected to the segment 46 normally holds the arm I46 (Figs. 6 and 12) in contact with a pin Ml of an arm I48 which is connected, through a gear I49, to an intermittent oscillatory drive mechanism.
With the arm I45 in its home position, as shown in Fig. 12, the segment 46 will position the drum 44 so that the cam groove Ma formed therein will hold the plate 42 and sleeve 2| in their extreme right hand position, thus placing the members 25 in their normal ineffective positions.
After the amount differential actuators I3 are adjusted, the arm I48 is rocked counter-clockwise (Fig. 12) until the pin MT assumes the position designated by Ml, and the arm I48 is not returned clockwise to its home position until after the actuators I3 are restored to their initial positions. During the counter-clockwise movement/of the arm M8, the segment 46, under the action of a spring 52 (Fig. 4) tends to follow 3 the arm I48 in its counter-clockwise movement. However, such counter-clockwise movement of the segment M5 is prevented by a pin All thereon contacting the upper end of a slot 48 formed in an adjusting segment M- loosely mounted on the sleeve connecting thearm 40 with the gear M53 (Fig. 6). The segment 49 serves to set the proper tens carrying mechanism, as will be hereinafter described. A spring 59 normally tends to hold the segment 49 in contact with a pin 52a of an arm 5| (Figs. 4 and 6). The arm 5| is connected, by a sleeve, to a gear |4| freely mounted on the shaft 35, and the gear |4| is connected to an intermittent oscillatory drive mechanism (not shown). position in Fig. Before the adjustment of the amount differential actuators I3 takes place, the oscillatory drive mechanism just referred to rocks the arm 5| in a counter-clockwise direction until the pin 5|a assumes the position designated by The plate 42 is provided with a roller" The segment 45) is shown in its home 5M (Fig. 4). The arm 5I is not returned to its home position until at the end of the operation. When the arm 5I moves counter-clockwise, the spring 50 moves the segment 49 so that the pin 41 is free to move upwardly in slot 48, and the spring 52 rocks the segment 46 counter-clockwise to follow the arm I48. When the segment 46 is thus rocked counter-clockwise it will, through V the gears 45, I53, and I5I, rotate the drum 44 an Y for the purpose of rotating the drum 44.
extent commensurate with the totalizer selecting key depressed. At such time, the gears I52 and I54 are held stationary by the totalizer selecting lever I51 to create a planetary gearing effect The cam groove 44a is of such shape that when the drum 44 is rotated as just described it will shift the plate 42 and sleeve 2| toward the left to engage the members 25 with the internal teeth 24 of the adding wheels Hl, thus coupling the adding wheels of the totalizer selected to their corresponding setting wheels I2.
After the amount differential actuators I3 are returned to their home positions, the arm I48 is restored to its initial position by the oscillatory drive mechanism previously referred to. During such clockwise movement, the arm I48 coacts with the pin M1 to return the arm I46 and segment 46 to their home positions. Such restoration of the segment 46 to its home position causes the drum 44 to be rotated to shift the plate 42 and sleeve 2| to the right to restore the members 25 to their extreme right hand ineffective positions. I
Totalizer selecting mechanism A bank of totalizer selecting keys 88 (Figs. 1 and 2) is provided for determining the extent of shifting movement imparted to the members I5 and 25 to selectively couple the adding wheels III of a, plurality of totalizers totheir respective common setting wheels I2.
Each arm of the setting segments 38 and 49 is provided with two stop faces 53, 54 and 55, 56, respectively (Fig. 1). With the machine at rest, the stop face 53 of the segment 38 contacts one end of a zero stop pawl 51 pivoted on a stud 58 of a totalizer key bank frame 58a. A spring 59 normally urges a pin 68 of the zero stop pawl 51 into contact with a projection SI of a detent 62 carried by two arms 62a and 62b pivoted to the key bank frame 58a. The detent 62 is normally urged downwardly by a spring 53 until the arm 62a contacts stationary stud 64 carried by the frame 58a. With the zero stop pawl 5! in the position just described, the segment 38 is thereby held in its zero position against the action of the spring 39 (Fig. 3) when the rocking arm 40 is actuated. If, however, the zero stop pawl 51 is moved out of the path of the stop face 53, by de-- pression of one of the totalizer selecting keys 83 as will be hereinafter described, the segment 38, under the action of the spring 39, is rocked clockwise to follow the arm 4|] until its stop face 54 strikes the lower end of a depressed key 80. When this occurs, the arm 48 continues its invariable rocking movement until the pin 48a assumes the position designated by 4M, and when moved counter-clockwise to its home position restores the segment 38 to its normal position. During such clockwise movement of the segment 38, the drum 44 is rotated in the manner previously described to shift the shaft 20 and sleeve I4 toward the right an extent commensurate with the key depressed, to engage the members I5 with the adding wheels I0 of the totalizer corresponding to the depressed key 88.
If the Zero stop pawl 57 is not moved out of its effective position by depression of one of the keys 80, the segment 38 is thus prevented from following the arm 48 in its clockwise movement. Since the pin 38 abuts against the lower end of the slot 31 (Fig. 3) the segment 34 is prevented from moving clockwise to follow the arm I44. Consequently, the shaft 25 and sleeve I5 associated therewith are not shifted to the left and the members I5 are not moved out of their normal ineffective positions.
With the machine at rest, the stop face 55 of the setting segment 49 contacts one end of a zero stop pawl 65 pivoted to the frame 58a. A spring 66 normally urges the pawl 65 counter-clockwise to cause a pin 61 thereon to abut against a projection 68 formed on a detent 59 (Fig. 2). The detent 69 is carried by a pair of arms 69a and 69b pivoted to the key frame 59a. The detent 69 is normally urged downwardly by a spring I0 to cause the arm 89a to abut against the pin 64. With the zero stop pawl in the position just described, the setting segment 49 is thereby held in its zero position, against the action of the spring 59 (Fig. 3), while the arm 5| (Fig. l) is rocked counter-clockwise during an operation of the machine.
Depression of any of the upper four totalizer selecting keys 89, through means to be later described, causes the zero stop pawl 55 to be rocked out of the path of the stop 55 on the setting segment 49. Thus the segment 49 will, under the action of the spring 58, follow the counter-clockwise movement of the arm 58 during an operation of the machine until the stop 56 on said segment strikes the end of the depressed key. This arrests the counter-clockwise movement of the segment 49 but the arm 5| continues its invariable counter-clockwise movement until the pin 5m reaches a position designated by 5Ia' (Fig. 1). Such counter-clockwise movement of the segment 49 clears the path of the stud 41, whereupon the spring 53 (Fig. 4) rocks the segment 4% counter-clockwise to rotate the drum 44 in the manner hereinbefore described. Such rotation of the drum 44 causes the shifting of the plate 42 and sleeve 2I toward the left a distance commensurate with the key 89 depressed. This causes the members 25 to engage the adding wheels If of the totalizer selected by the depressed key and thereby couple said wheels to their respective setting wheels I2, as previously explained.
Depression of any one of the lower five totalizer selecting keys 84) causes the Zero stop pawl 51 to be rocked out of its normal effective position. The means actuated by said keys 89 for accomplishing this result will. now be described.
The detent 62 has inclined surfaces 72 coacting with pins 73 on the five lower keys 89. Whenever one of the five lower keys 89 is depressed, the pin 73 will coact with one of the inclined surfaces I2 on the detent 52 and cam the latter upwardly against the action of a spring 63. Durmg such upward movement, a projection SI on the detent 62 will coact with the pin 68 and rock the zero stop pawl 57 clockwise, against the action of the spring 59, thus removing the righthand end of said pawl (Fig. 1) out of the path of the stopping face 53 on the setting segment 38. This permits the segment 38 to be moved by spring 39 until arrested by the stem of a depressed key 88, as hereinbefore explained.
Pivotally mounted on pins I6 carried. by the detent 52 are five pawls '55 having inclined surfaces 15a. The pawls I are normally held against pins I8 of the detent 62 by springs 11, in which positions the upper edges of the pawls I5 are out of the path of movement of the pins I3 on the keys 3B. When, upon depression of one of the five lower he s 55, the detent 52 has been moved upwardly, the pawls I5 are thereby rocked so that the inclined surfaces I505 thereof confront the key pins l3 of the four remaining undepressed lower keys 80. Thus, if one of the four undepressed lower keys 80 is depressed, the pin I3 thereon will coact with the inclined surface 15a of its respective pawl I5 and earn the detent upward an additional extent. The pawl I5 of the first depressed key 80 above mentioned is then able to diverge against the action. of its spring 17, whereas an upper projection I4 on the detent 52 coacts with a pin 6'! on the zero stop pawl 65 and rocks the latter clockwise to remove the right-hand end thereof from the path of the stop face 55 on the segment 59.
Similar to the detent 62, the detent 69 (Fig. 2) has four inclined surfaces I9 thereon cooperating with the pins I3 of the four upper totalizer selecting keys 8!). Depression of any one of said keys 80 causes the pin I3 to coact with one of the inclined surfaces I9 and cam the detent 69 upwardly against the action of a spring In. During such upward movement of the detent 69 a projection 68 formed thereon coacts with a pin 51 on the zero stop pawl 55 and rocks the latter clockwise out of the path of the stop face 55 on the setting segment 49. During such movement of the detent 59 another projection 82 thereon is moved into contact with the pin 60 on the zero stop pawl '51. Also pivotally mounted on pins 83 carried by the detent 69 are four pawls 34 having inclined surfaces 84a. Springs 85 normally hold the pawls 84 against pins 85 on the detent 69. If, after depressing one of the four upper keys 8!! and thereby rocking the detent 59 upwardly to move the pawl 55 out of the path of the segment d9, another one of said upper keys on is depressed the pin I3 thereon will coact with the surface 84a of its respective pawl 84 and cam. the detent 69 further upward. Such additional upward movement of the detent 69 causes the projection 82 to rock the zero stop pawl 51 out of the path of the stop face 54 on the setting segment 38.
From the foregoing description it will be understood that if no keys 8B are depressed, the setting segments 38 and 49 are retained in their zero positions by the zero stop pawls 51 and 55, respectively. If only one key 8L! is depressed in either the upper group or lower group of keys, then either the setting segment 49 or the segment 38 is released for operation and is rocked in the manner hereinbefore described until it is stopped by the stem of the depressed key, whereas the other setting segment corresponding to the other group of keys remains in its normal position. On. the other hand, if a key 80 is depressed in each of the two different groups, i. e., the upper and lower groups, both setting segments 49 and 38 are released and each of said segments is rocked until stopped by the depressed key nearest thereto. When two keys B9 are depressed in one and the same group, either upper or lower, both Zero stop pawls 55 and 51 are thrown out as above described to permit both the setting segments 45 and 35 to be moved until stopped by the stems of the two depressed keys.
Tens carrying mechanism There are two groups of tens carrying mechanisms provided in the present machine, one group being shiftable to effect the proper transfer for any totalizer selected by the coupling members i5 and the other group being shiftable to effect the transfer for any totalizer selected by the coupling members 25.
The means for shifting the first of the above mentioned groups of tens carrying mechanisms now be described. The segment 38 (Figs. 3 ail-J. 6) meshes with a gear 89, loose on a shaft "i, which gear meshes with another gear 90 se- 01 ed to a shaft 9!. Also secured to the shaft 5% is b... am 523 having a cam groove 92a engaged by a guide roller 93 of a plate 94 shiftably mounted on rods 95 and 91. An angular'shaped bail connects the plate 94 with another plate (not shown) to form a shiftable frame for carrying, in a manner to be hereinafter described, the
tens carrying mechanism into alinement with whichever totalizers are selected by the members it. From the foregoing it will be seen that when the segment 98 is rocked clockwise, as previously described, it will, through the gears 89 and 9B. rotate the drum 92 clockwise (Fig. 3). an extent commensurate with the depressed totalizer selecting key M. The drum 92 in turn, through the cam groove 92a and roller 93, shifts the frame comprising the plates 94 (only one of which is shown) and hail 95 a like extent to properly position the tens carrying mechanisms, associated with the members I5, into alinement with the totalizer elements which are engaged by the associated members I5.
The means for shifting the other groups of tens carrying mechanisms, which are associated with the members 25, will now be described. The setting segment 49 (Figs. 4 and 6) meshes with a gear 58, loose on the shaft 88, which gear in turn meshes with another gear 99 freely mounted on the shaft 9! and connected by a sleeve 99a to a beveled gear I 58. The gear I58 meshes with a beveled pinion I59 pivoted on a stud IEI secured to the hub of a drum I00. The pinion I59 meshes with beveled gear I50 rigidly connected to a gear I53 engaging an intermediate gear I64 fast on the shaft 88. Also secured to the shaft d8 is another gear I8I engaging the toothed sector I55 of the totalizer selecting lever I5I. Inasmuch as the lever I5! is not operated during adding operations it will. through the means just described, cause the gears 63 and I553 to remain stationary. It will thus be seen from the above that when the setting segment 49 is rocked counter-clockwise, previously described. during adding operations it will, through gears 98, 99. and I58, rotate the beveled pinion I59. With the beveled gear I (it! held stationary, as previously mentioned, the pinion it?!) will rotate around said gear in a planetary manner to rotate the drum I95. The drum Hi l has formed therein a cam groove lillia engaged by a guide roller NH of a plate I02 shiftably mounted on the rods 96 and 91. The plate N12 is connected by means of an angular shaped hail 5833 to a second plate I02 (not shown) to form a frame shiftably mounted on the rods 96 and 3?. This frame carries the tens carrying mechanisms for any totalizers selected by the members 25.
The cam grooves and lfllla in the drums 92 and mo, respectively, are shaped the same as the corresponding grooves in the drums 3i and it previously described. Inasmuch as the setting segments 34 and 38 are moved simultaneously and like extents, the members l5 and the frame 94-45, carrying the tens carrying mechanisms, will thereby be shifted simultaneously and like extents. Also, since the setting segments 26 and 59 are moved simultaneously and like extents, the members 25 and the frame I02-I03, carrying the tens transfer mechanisms, will thereby be shifted simultaneously and like extents. other words, the frame Ste-95 will be shifted in the same direction as the members I5, while the frame Lit-I03 will be shifted in the same direction as the members 25.
The tens carrying mechanism associated with the members I5 and carried by the shiftable frame t l-05 will now be described. The horizontal shank of the angular bail 95 is provided with a plurality of projections I05 (Figs. 8 and 10), the space between each pair of which forms a recess for each denominational order, to receive an arm I050. connected by a bail H3501 to a tens carrying lever I05. The levers I05 are loosely mounted on a rod 805 and are shiftable with the frame 9 l-95. Each of the levers I55 corresponds to a different denominational order and carries a tens counter-tooth I01. Each tooth I? is slidably mounted on its respective lever E by means of two elongated slots through which project pins I055 carried by the lever. In addition, each tooth I0! is provided with a cam slot concentric with the rod I05 and engaged by a rod I05 carried by the totalizer carriers 25. The tooth i0! of each denominational order and its appropriate member I5 are in one and the same plane. Thus, due to the fact that the sleeve i l and the frame 92-95 are shifted together and in the same manner, the tooth I01 will always be opposite the adding wheel I0 which is engaged by its respective member I5 to couple said wheel to its setting wheel I2. It will thus be seen that the tooth I071 is shiftable with the lever I05 and, through its mounting on the pins M3517. is also adapted to be shifted by the rod N33 with the totalizer carrier It When the latter receives its rocking movement.
Each lever 35 has an extension @050 provided with three notches. These notches cooperate with a rod H0 (Figs. 10 and 'l) of a springpressed locking bail I I I, pivotally mounted on a shaft H2, extending the full width of its respec: tive denominational order. During actuation of an adding wheel. I0, when passing from 9 to 0, the long tooth I0a thereon will coaot with the upper end of the tooth 501 and rock the lever Hi5 counter-clockwise, in which position it is held by the rod l I0 which moves into the second notch of the extension I050 when the arm. I05 moves downwardly. The lever I05 is given an additional counter-clockwise movement by means to be hereinafter described, whereupon the rod 1 I0 enters the third or uppermost notch of the extension i55c and holds the lever I05 in such position. The upper end of the arm I05a on the lever I05 is provided with a cam slot I I3- which is engaged by a pin I I4 of a toothed sector I I5 pivoted on a shaft H5. In rest position, the pin H4 abuts the left-hand end portion of the slot I'I'E, which portion is concentric with the shaft 500. This prevents the sector II5 from being rocked during the first counter-clockwise movement im parted to the lever I05, while during the second counter-clockwise movement given to the lever H55 the sector H5 is rocked counter-clockwise by the lower portion of the slot H3 in the arm I05a.
Each toothed sector H5 is guided by a pair of extensions Ii'l (Fig. 8) integral with the vertical shank of the bail 95, there being a pair of such extensions associated with each enominational order. Through such guides, the toothed sectors II5 are shifted with the tens carrying levers I 05 so that the sectors 555 are always positioned opposite the adding Wheel I0 of next higher denominational order from the adding wheel Iii coupled by the member I5 to the setting wheel I2.
The other group of tens carrying mechanisms, which corresponds to the members 25 and is associated with the shiftable frame I02-I03, will now be described. Allotted to each denominational order is a tens carrying lever I20 (Fig. 11) which is shaped like, and functions in substantially the same manner as, the tens carrying 1ever I05 before referred to. Each lever I20 is connected by a bail I20d to an arm I20a which is associated with the next higher denominational order. The levers I05 and [20 are both loosely mounted on the shaft I05 (Fig. 8), in alternate sequence, and are adapted to be operated independently of each other. The arms I 20a of the levers 52:0 are embraced by extensions I22 on the bail I03 formed as part of the shiftable frame I02-I03. Whenever the frame I02I03 is shifted laterally in the manner hereinbefore described, the levers I20 will be shifted therewith.
Slidably mounted on pins I201) of each lever I20 is a tens counter tooth IZI, which is constructed and operates like the tens counter tooth I07 previously described in connection with the lever I05. The rod I08 is straddled by a bifurcated portion of the tooth I2I and serves to guide the tooth in its movements. The tooth I2 I, like the tooth I01, is always positioned opposite the adding wheel I0, of its respective denominational order, which has been coupled by the member 25 to the setting wheel I2.
Like the levers I05, each lever I20 has an extension I200 provided with three notches. These notches cooperate with a rod I23 of a springpressed lock bail I24, pivotally mounted on the shaft H2 (Fig. 7), extending over the full width of its respective denominational order. During actuation of an adding wheel I0, as the latter passes from 9 to 0, the long tooth Illa thereon will coact with the upper end of the tooth I2I and thereby rock the lever I20 counterclockwise, in which position it is held by the rod I23 engaging the second notch of the extension I200. The lever I20 is given an additional counter-clockwise movement by means to be hereinafter described, whereupon the rod I23 enters the third or uppermost notch of the extension I200 and holds the lever I20 in such position. The upper end of the arm I20a of the lever I20 is provided with a cam slot I25 which is engaged by a pin I26 of a toothed sector I21 pivoted on the shaft IIS. In rest position, the pin I26 abuts the left-hand end portion of the slot I25, which portion of the slot is concentric with the shaft I06. This prevents the sector I21 from being rocked during the first counter-clockwise movement imparted to the lever I20, while during the second counter-clockwise movement given to the lever I20, the sector I 2! is rocked counter-clockwise by the lower portion of the slot I25 in the arm I20a.
Each toothed sector I21 is embraced by projections I28 integral with the bail I03 so as to cause the sectors I21 to take part in the shifting movement which the frame I02-I03 receives. In this manner, the sectors I2'I are always positioned opposite the adding wheel II) of the next higher denominational order from the adding wheel I coupled by the member 25 to the setting Wheel I2.
The means for imparting the second counterclockwise movement, above referred to, to the tens carrying levers I and I20 will now be described. Each of the levers I05 and I20 is pro vided with an extension I05 and. I20 respec" tively. The extensions I05 and I207 of the two levers I05 and I20 associated with each denominational order cooperate with a tens carrying bail I30 (Figs. 8, 9, l0, l1, and 13), there being one of such bails associated with each denominational order. The bails I30 for the different denominational orders are loosely mounted on a shaft I3I, each of said bails being connected to a cam disc I33 by means of a pitman I32 having a guide roller I32a coacting with a. cam groove I33a in said disc. The cam discs I33 are secured to a shaft ISE which is given one complete rotation in a counter-clockwise direction at the end of each operation of the machine. The cam grooves I33a in the discs I33 are so shaped that, after the amount differential actuators I3 have been restored to their home positions, they rock the bails I30 first clockwise, then counter-clockwise past their home positions, and finally clockwise to their initial positions. The cam groove I33a of the discs 533 are so formed as to actuate the bails in successive order, beginning with the one associated with the lowest denominational order.
It will be seen from Figs. and 11 that, if the levers I05 and I 20 are not given the initial counter-clockwise movement previously referred to, the bails I30 associated with said levers will pass idly beneath the projections I05f and I20f, respectively, of the levers, without having any eifect on the latter. If, however, when an adding wheel Illpasses from 9 to 0, one of the levers I05 or I20 is rocked counter-clockwise into the position shown in Fig. 9 by means of the tens tooth Illa, the projection I05f or I20 thereof is moved directly into the path of its respective bail I30. when the bail E30 is rocked clockwise it will coact with either the projection "f or If, depending upon which has been moved into the path thereof, and rock the lever I05 or lever I20 counter-clockwise until it assumes the position shown in Fig. 13. When this occurs, the cam slot N3 of the arm I05a or the cam slot I in the arm IiZIlct will cam the pin. H4 or I25 and tens carrying sector H5 or I21, respectively, in a counter-clockwise direction.
After the members I5 and 25 and the tens carrying levers i635 and Mid are adjusted laterally into alinement with the selected totalizer, the amount differential actuators I3 are rocked clockwise an extent determined by the amount keys. Just before the actuators I3 are rocked counterclockwise to their home positions, the totalizer carriers I 5 are rocked counter-clockwise to engage the various setting wheels I2 with. the actuators I3, so that the latter will, during their counter-clockwise movements, actuate the wheels I2 to add upon the adding wheels I0 of the tota1izers selected the amounts which were set up on the actuators it under control of the amount keys. After the actuators 53 are thus restored to their home positions, the members I5 and 25 are returned to their normal ineffective positions and the totalizer carriers It are rocked clockwise to engage the adding wheels iii of the selected totalizers with the tens carrying sectors H5 and I21. Thus, if any of the adding wheels l0 passes from 9 to 0, the long teeth I Do thereon will actuate their corresponding tens carrying levers I05 or I20 to adjust the toothed sectors I I5 or I21 so that upon rotation of the cam discs I33 the sectors will be actuated thereby in successive order to add"onc upon the adding wheels I0 of next higher denominational order.
Should an adding wheel I0 of next higher denominational order, when having I transferred thereto, pass from 9 to 0, the tens tooth I0 thereon will cause one of the projections I05 1 and i223 on its corresponding tens carrying levers I05 and I20, respectively, to be moved into the path of the appropriate bail I shortly before the latter receives its rocking movement On the clockwise movement of the bail I30 the lever I05 or I20 wiil he thereby rocked further counter-clockwise and thus cause one of the sectors I I5 and I21 associated therewith to be rocked likewise. This causes the sector to add 1 onto the adding wheel I0 of still next higher denominational order. After the proper carry has been eifected, the totalizer carriers I0 are rocked counter-clockwise to return the row of totalizers to its normal ineffective position. Also near the end of the cycle of operation of the machine, the cam discs I33 serve to restore the displaced tens carrying mechanisms to their normal positions by first rocking the bails 1 30 counter-clockwise past their normal positions, at which time the balls I30 strike projections I05 and Il-lflg on the levers I05 and I20, respectively, and rock said levers clockwise to return the toothed sectors H 5 and I 2'! to their normal positions, after which the bails I30 are again rocked clockwise to their normal positions.
Adding operation A brief description will now be given of the operation of the machine when performing an adding operation wherein a key is depressed in each of the upper and lower groups. The amount is entered upon the amount keys (not shown) and two of the totalizer selecting keys 80 are depressed. Depression of the keys 00 moves the zero stop pawls 5'5 and 65 out of the path of the two setting segments 38 and 40 (Fig. 1). Upon operation of the machine, the amount differential actuators I3 are moved clockwise an extent commensurate with the value of the depressed amount keys, while the two actuating arms 00 and I44 are rocked clockwise and the two actuating arms 5! and I48 are rocked counter-clockwise (Figs. 1 and 12). springs 33 and 4|, the two setting segments 38 and 34 follow the arms 40 and I64 in the latters clockwise movement until the face 54 on the segment 30 strikes the lower end of a depressed key 80 and is thereby arrested in its clockwise move ment. This causes the pin to abut the lower end of the slot 37 in the segment and thereby arrest the movement of the segment 34 in a position corresponding to that of the segment 38. In a similar manner, the setting segments 49 and 46, under the action of their springs 50 and 52, follow the actuating arms 5| and M8 in the latters counter-clockwise movement until the face 50 on the segment 49 strikes the lower end of a depressed key 80, thereby arresting the counterclockwise movement of the segment 09. The setting segment 45, with its pin iil abutting the upper end of the slot 43 in the segment 43, is also stopped in a position corresponding to that in which the segment 69 is stopped.
Due to the fact that the two setting segments Under the tension of their 34 and 3B are moved the same extent, as above described, they will, through the medium of the drums 3! and 93, respectively, shift the sleeve I4 and the members I5 thereon (Fig. 7) and the frame 94-35 (Fig. 6) toward the right. This causes the members I5 to couple to the setting wheel i2 the adding wheels of the totalizer selected and aline the tens counter teeth I01 with said adding wheels III. At the same time, the tens carrying sectors II5 are alined with the corresponding adding wheels II) of next higher denominational order.
As the two setting segments 46 and 45 are moved counter-clockwise like extents, they will, through the drums M and I80, respectively, shift the sleeve 2i and the members 25 thereon (Figs. 5 and '7) and the frame I02, I03 to the left an extent determined by the appropriate key 80 which has been depressed. This causes the members 25 to couple to the setting wheels I2 the adding wheels II! of the totalizer selected and alines the tens counter teeth I81 with the appropriate adding wheels. At the same time, the tens carrying sectors I21 are alined with the corresponding adding wheels ID of neXt higher denominational order.
After thus selecting the two desired totalizers in the manner above described, the totalizer carriers it are rocked counter-clockwise suflicient to engage the setting wheels l2 with the amount differential actuators I3 just before the latter begin their counter-clockwise movement to home position. Thus, as the actuators I3 are moved counter-clockwise they will actuate the setting wheels I2 and add upon the adding wheels II) of the totalizers selected, which have been coupled to the wheel It by the members I5 and 25, the amount set up on the actuators 23.
If one of the adding Wheels II], during such adding operation, passes from 9 to the tens tooth lea thereof will strike the appropriate tens counter tooth I91 and I2I and rock the corresponding tens carrying lever I and I20 counter-clockwise (Fig. 9). This positions the projection N) or I201, depending upon which one of the levers Hi5 and I is effected, in the path of the tens carrying bail I35 associated therewith. When the actuating arms M l, and I48, (Fig. 6) are restored to their normal positions, the setting segments 34 and 48 (Fig. 3) are thereby also returned to their home positions. This causes, through the drums 3i and M, the shifting of the sleeves I4 and iii to their normal ineffective positions so that the members I5 and disengage all. adding wheels If! from the setting wheels I2. whereupon, the totalizer carriers I6 are rocked clockwise to engage the adding wheels I0 of the two selected totalizers with the tens carrying sectors H5 and I21. The shaft I34 then commences its counter-clockwise rotation and causes the cam discs I33 to first rock each of the bails I clockwise, in successive order, beginning with the bail for the lowest denominational order and finishing with the bail for the highest denominational order. During such clockwise movement, the bails I35 will coact with the projections I05 and I'Zilj and rocks the levers I and E20, respectively, counter-clockwise. This will cause the arms "35a and I2fia, through the slots H3 and I25, respectively, formed therein, to rock the tens carrying sectors H5 and I25 counter-clockwise. The latter, being engaged with the adding wheels of next higher denominational order, will advance said wheels one step of movement. By
rocking the bails I30 clockwise in successive or der, beginning with the lowest order and finishing with the highest order, continued tens carrying is provided.
After eifecting the transfer of 1 from the Wheels of lower order to the wheels of next higher order, the totalizer carriers I6 are rocked counterclockwise to return the row of totalizers to its normal ineffective position (Fig. 10). During their return movement, the tens carrying bails Iiill are rocked by the cam discs I33 first counterclockwise past their normal positions and then clockwise to their normal positions. The bails during their counter-clockwise movements, coact with the projections IDBg and I2Bg and rock the levers I55 and I20, together with their tens carrying sectors H5 and I21, respectively, clockwise to restore them to their normal positions. At the same time, the actuating arms 59 and 5! (Figs. 3 and l) are rocked counterclockwise and clockwise, respectively, to their normal positions and in so doing return the setting segments 38 and 49 to their home positions. Such movement of the segments 38 and 49 causes the frames 94, 95 and I02, I03 to be shifted to their home positions, so that the tens carrying elements I05, I55 and I20, I21 are restored to their initial positions. Finally, the amount keys and totalizer selecting keys 8!) are released and returned to their normal undepressed positions by means old and well known in the art.
Total taking operation When taking a total from any of the totalizers, the totalizer selecting lever I51 (Fig. 14) is used instead of the keys 80 for selecting the proper totalizer. The lever I51 is loosely mounted on the shaft 35, adjacent the bank of keys 85, and has formed integral therewith the toothed segment I55 previously referred to. As already explained, the segment I56 is connected by means of the gears i550, I55b and I54 (Fig. 5) to the bevelled gear I52, and is, likewise, connected by means of the gears I8I, I64 and I63 (Fig.6) to the beveled gear I58. Consequently, when the totalizer lever I51 is adjusted to select a particular totalizer, the segment I56 will rotate the two beveled gears I52 and IiiD accordingly. Since the beveled gears I53 and 558 are held stationary at this time, the gears I52 and Hit) will rotate the beveled pinions I5I and I59 around the stationary gears I53 and I58 in a planetary manner, thereby causing the cam drums 44 and 199 to be rotated accordingly. This causes the sleeve ill and the members 25 thereon, together with the frame I52, I03 carrying the tens carrying elements I25, I2I and I21, to be shifted to the left, so that the members 25 will couple the adding wheels Iii of the selected totalizer with the setting wheel I2, while the tens counter teeth I2I are positioned opposite the coupled adding wheels. From the foregoing it will be seen that the totalizer selecting lever I51 may be adjusted to cause the members 25 and the associated tens carrying elements to be set for all the adding wheels of any of the totalizers, during which time the members I5 and associated tens carrying elements remain in their normal ineffective positions.
The machine is adapted to perform two kinds of total taking operations, namely, a total or totalizer reset operation and a sub-total or read operation. The time of engagement and disengagement of the setting wheels It with the '16 amount differential actuators I3 governs which one of said kinds of operation the machine performs. For instance, to perform a total taking or totalizer resetting operation, the setting wheels I2 are engaged with the actuators I3 at the very beginning of the latters clockwise movement. Consequently, the actuator I3 will rotate the setting wheels I2, together with the adding wheels I coupled thereto, counter-clockwise until the tens teeth Ifla on the adding wheels of the selected totalizer strike the upper ends of the tens carrying teeth I2I and are arrested thereby in their zero positions. The tens carrying teeth I2I are provided with noses I2Ia, which are so arranged that when the tens teeth I0a strike these noses I2Ia during reset operations, the levers I20 will not be rocked by the last mentioned teeth. If the setting wheels I2 are disengaged from the actuators I3 before the latter begin their counter-clockwise movement to home position, the adding wheels I0 of the selected totalizers will be left standing in their zero positions. However, if the setting wheels I2 are not disengaged from the actuators I3 until after they are returned counter-clockwise to their home positions, the amounts originally standing on the adding wheels of the selected totalizer will be added back on said wheels again, as is old and well known in the art.
Transferring a total from one totalizer to another totalizer on the same totalizer Zine Means is also provided for transferring atotal from one totalizer to any other desired totalizer on the same totalizer line. A control lever I10 (Fig. 14) is. provided for conditioning the machine to perform various kinds of operations, namely, adding operation, total taking or totalizer reset operation, sub-total taking or read operation, and transfer total operation. It is the last mentioned operation which will now be considered.
The control lever I10 has formed integral therewith a segment I1I (Figs. 14 and 15) having a cam groove I1Ia which is engaged by a guide roller I12 of a bail I13 shiftably mounted on a stud'I15 carried by one of the side frames. The bail I13 has formed thereon a forked arm I14 engaging an annular groove formed in the hub of a broad gear I11 shiftably, as well as rotatably, mounted on the shaft 35. Fast to the gear I11 is an angular lever I16. The gear I11 is constantly in mesh with a segment gear I18 secured to the shaft I10a. The shaft I18a and ear I18 are rocked first counter-clockwise and then clockwise during each operation of the machine by the intermittent oscillatory drive mechanism (not shown) hereinbefore referred to. This will cause, through the meshing of the gear I18 with the gear I11, the lever I16-to be rocked first clockwise and then counter-clockwise to its home position during each operation of the machine.
If, however, the lever I10 is set in its transferring position, the cam groove I1Ia causes the bail I13, gear I 11 and lever I16 to be shifted toward the left, whereby the lever I16 is moved into the path of the stud I80, while the'gear I11 still remains in mesh with the gear segment I18. Thus, when the gear I18 is rocked counter-clockwise, as previously described, it will, through the gear I11, rock the lever I16 clockwise. During such clockwise movement of the lever I16 the end thereof will strike the stud I80 of the totalizer selecting lever, which has been positioned according to the totalizer selected, and rocks said lever clockwise to restore it to its normal position.
The manner in which the above mentioned mechanism functions to transfer a total from one totalizer to another totalizer on the same totalizer line will now be described.
When preparing the machine for a transfer operation, the positioning of the control lever I10 to its transfer position causes the lever I18 to be moved into the path of the stud I80 on the totalizer selecting lever I51, as already stated. The latter is positioned to select the totalizer from which it is desired to take a total, whereby, through the gears 155e, I551), I54, I52, II and I53 and the cam drum 44 (Fig. 5) the members 25 are so shifted to the left to couple the adding wheels ill of said selected totalizer with. their associated setting wheels I2. At the same time, the lever I51 (Fig. 6), through the gears I8i, I04, I63, I60, I39 and I58 and the cam drum I00, causes-the appropriate tens carrying elements I28, I2! and I21 to be shifted to the left accordingly and placed opposite the coupled adding wheels I0.
The totalizer to which the total is to be transferred is selected by depression of one of the totalizer selecting keys 80 (Figs, 1 and 2) in' a manner previously described. At the beginning of such transfer total operation, the setting wheels I2 (Figs. and 1.2) are rocked into engagement with the differential actuators I3 as previously described, so that when the latter are rotated clockwise, the adding wheels II) of the coupled totalizer selected by lever I51 are rotated counter-clockwise until their tens teeth Ilia strike their associatedtens counter teeth I2I, whereby the adding wheels I0 are arrested in their zero position. The actuators I3 are likewise arrested at this point. With the totalizer thus reset to zero and the total taken therefrom now standing on the amount differential actuators I3, the arms 40,5I, I44, I48 and lever I16 are given their regular oscillatory movements. At this time the lever I16strikes the stud I8fi of the totalizer selecting lever I51 and restores the latter clock- Wise to its home position, whereby also the sleeve 2I' and the members 25 thereon, together with the frame I02, I03 with the appropriate tens carrying elements I20, I2I, I21, are returned to their normal ineffective positions. Thus the totalizer selected by the totalizer selecting lever I51 for the purpose of taking a total therefrom is now reset to'zero and the adding Wheels I0 thereof are uncoupled from the setting wheels I2.
If, in this connection, one of the five lower totalizer selecting keys 80 (Fig. 1) has been depressed, the setting segments 38 and 34 (Figs. 1 and 3), being released by the zero stop pawl 51 associated therewith, are ableunder the action of their springs 39 and 4!, to follow the actua ing arms 40 and I44 during their first rocking movement until both of said segments are stopped by the face 54 on the segment 38 striking the stem of the depressed totalizer selecting key 80. Through such setting of the segments 38 and 34, the members I5 and their associated tens carrying elements I05, I01, I I5 are shifted accordingly, so that the totalizer determined by the depressed key 80 is selected and coupled to the setting wheels I2.
If, however, one of the four upper totalizer keys 80 (Fig. 2) is depressed, only the zero stop pawl 65 will be thereby thrown out of its effective position. Therefore, during the first rocktion the amount difierential actuators ing movement of the actuating arms 5! and I48 (Fig. 6), the setting segments 49 and 46 (Figs. 2 and 4) under the action of their springs 50 and 52, respectively, follow the movement of the arms 5| and I48 until arrested by the face 56 on the segment 49 striking the stern of the depressed key 80. The arms 5! and I48 (Fig. 6), however, complete their first rocking movement, during which time the lever I16 (Figs. 14 and 15) restores the totalizer selecting lever 51 to its normal position. When this occurs, the difierential gears |5| to I53 inclusive, and I58 to I60, inclusive, (Figs. 5 and 6) rotate the drums 44 and I00, respectively, to cause the members 25 and the appropriate tens carrying elements I26, HI and I21 to be moved out of the positions they assumed under control of the totalizer selecting lever I51 and into new positions determined by the depressed key Bil. This causes the coupling and selection of the totalizer to which the total taken from another totalizer is to be transferred.
Now the amount differential actuators I3 are restored to their home positions, with the total standing thereon which was taken from the totalizer selected by the totalizer selecting lever I51, at which time the actuators will transfer such total to the newly coupled totalizer selected by the depressed key 80. If, during such transferring operation, some of the adding wheels I0 of the newly selected totalizer pass from 9 to 0, the proper tens carrying is effected by the appropriate tens carrying levers I05 or I20, said levers being rocked just as in regular adding operations. After the amount has been transferred to the secondtotalizer, the adding wheels I0 thereof are uncoupled from the setting wheels I2 by means of the members I5 or 25 being returned to their normal ineffective positions and the adding wheels Ill coupled with the appropriate tens carrying sectors 5 or I21 through the rocking of the totalizer carriers I6 clockwise. Rotation of the shaft I34 then causes the proper tens carrying to be completed in denominational order, after which-the totalizer row is rocked counter-clockwise to its nor mal or unengaged position (Fig. 10), while the tens carrying elements are restored to their initial positions.

Also in such modified form of the inven- I3 are constantly in. mesh with the broad setting wheels I2, which are rotatably mounted on a shaft I66. The coupling wheels I5 and 25' are in constant mesh with the setting wheels I2 and are carried by frames I4 and 2|, respectively. The
frames I4 and 2| correspond to the sleeves I I and 2| in the preferred form of embodiment of the invention, and like said sleeves have secured to the right ends thereof plates substantially like the plates 21 and 42, respectively.

The wheels I5, like the members I5, are shiftable toward the right to select the adding wheels of any one of the totalizers from the ninth down to and including the second totalizer, while the wheels 25', like the members 25, are shiftable to the left to select the adding wheels of any one of the totalizers from the first to and including the ninth totalizer.
