In order to shorten this time of operation, a novel totalizer-engaging mechanism has been developed, wherein a total operation occurs during a single machine operation. Prior to this development, a total operation required two machine operations, during which time the tens transfer operation and the restoring of the tripped transfer mechanisms occurred. It is therefore an object of this invention to provide a tens transfer mechanism which can be operated through primary and secondary transfer operations and can be restored to its home position during a total operation of a cash register which occurs during a single machine operation. It is another object of this invention to provide a mechanism for restoring tripped tens transfer mechanisms without the necessity of disengaging and re-engaging the totalizer wheels and the transfer mechanism as a distinct functional operation. It is a further object of this invention to provide a mechanism for allowing the entering of a tens transfer into the next higher order during and by the restoring of the tripped transfer mechanisms. It is another object of this invention to provide an aligning means associated with the tens transfer mechanisms to maintain the machine operation.

SUMMARY OF THE INVENTION A tens transfer mechanism including a transfer pawl tripped by a totalizer wheel, a transfer segment normally engaged by the transfer pawl when in an untripped position and disengaged when in a tripped position, and a bail member mounted adjacent said transfer segment and engaging said segment to restore those segments operated during the previous machine cycle while conditioning the segments for operation in the present machine cycle and subsequently releasing the segments to operation by the transfer pawls, whereby primary and secondary transfer operations will occur simultaneously. An aligner member cooperating with the transfer segment aligns the totalizer wheels when the totalizer wheels are moved into engagement with the adding segment.

DESCRIPTION OF THE PREFERRED EMBODIMENT The invention is directed to a tens transfer mechanism utilized in a cash register of standard construction, which includes a plurality of amount key banks. As is well known in the art, mounted in each amount key bank is a rack member which is settable to a position by engaging the stem of the depressed key in the amount bank. An adding segment which engages a rack member is also set to a position commensurate with the key depressed. During an add operation, totalizer wheels are brought into engagement with the adding segments alter the segments have been set by the depressed key. When the rack member and the adding segment are returned to their home position, the amount represented by the key depressed is added into the totalizer wheels. The totalizer wheels are then disengaged from the adding segment.

As disclosed in the co-pending United States patent application titled Totalizer Control Mechanism," Ser. No. 87,767 filed in the names of I-Ians-Juergen Krause and Johannes Rindfuesser, the co-inventors in this present application, the engagement and disengagement of the totalizer wheels during an add, sub-total, or total-taking operation occur during a single machine operation. At the end of the machine operation, the rack members in each of the amount banks are in an adjusted position and are returned to their home position during the first part of the next machine operation. By this construction, the operation of the cash register is considerably shortened. The present invention is utilized with this type of totalizer operation and concerns the tens transfer operation, which allows a total or subtotal operation to occur during a single machine operation.

As is well known in the art, the tens transfer mechanism functions to add one" to the next higher order totalizer wheel when, during an adding operation, a value is added to the lower order totalizer wheel which moves the totalizer wheel from its ninth position to its zero position. This movement of the totalizer wheel will trip the tens transfer mechanism, which, at a subsequent time in the machine operation, will rotate the next higher order totalizer wheel one position. This is known as a primary transfer operation. If, as a result of the primary transfer operation, the next higher totalizer wheel is moved from its ninth position to its zero position, a secondary transfer operation is eflected. The present invention allows both of these transfer operations to occur simultaneously.

Referring now to FIG. 1, there are shown the totalizer-engaging mechanism and the tens transfer mechanism utilized in the present embodiment. Included in the totalizer-engaging mechanism are a number of totalizer wheels 20 secured to a shaft 21 mounted between a pair of plate members 22, which in turn are secured to a shah 23 rotatably mounted within the frameworK (not shown) of the machine. Secured to the right-hand plate member 22 is a roller stud 24, the end of which is positioned within a cam slot 25 located in a totalizer-engaging plate 26 rotatably mounted on a shaft 27 and secured to a hub member 28, the other end of which is secured to an operating plate 30. Secured to the end of the shaft 27 is a driving arm 31, which contains a slot 32, within which is positioned a stud 33 (FIG. 2) mounted on a control plate 34. As shown in FIG. 2, the driving arm 31 is one of three such arms engaged by the control plate 34, which in turn is rotatably mounted on a shaft 35. Each driving arm 31 controls a totalizer line, as disclosed in FIG. 1, there being three totalizer lines in the machine.

The control plate 34 contains a slot 36, within which is positioned a stud 37 secured to one end of a cam follower arm 38 rotatably mounted on a shaft 40. A pair of rollers 41, mounted on the arm 38, engage a pair of cam plates 42 secured to the main cam shaft 43. Rotation of the main cam shaft 43 during a machine operation rocks the cam follower arm 38 first clockwise about the shaft 40 and then counter-clockwise. The clockwise movement of the cam follower arm 38 results in the clockwise movement of the driving arms 31.

As viewed in FIGS. 1, 2, and 3, secured to each of the driving arms 31 is a rod 44, which extends through a slot 45 in the operating plate 30. Rotatably mounted on the operating plate 30 is a sensing arm 46, which is urged counter-clockwise about its pivot point by a spring 47 secured between the arm 46 and a stud 48 mounted on the operating plate 30. As more fully disclosed in the co-pending United States patent application of Krause and Rindfuesser cited previously, the counter-clockwise movement of the sensing arms 46 under the action of the spring 47 is controlled by a selecting disk 50 (FIGS. 3 and which is rotated during a machine operation to present either a high control surface 51 or a low control surface 52. or both, to the sensing arm 46 during a machine operation, whereby, upon sensing a low control surface 52, the am 46 is rotated counter-clockwise a sufficient distance to allow a lower stop portion 53 of the arm 46 to engage the rod 44. This engagement will allow, during a clockwise movement of the driving arm 31, the rod 44 to pick up the operating arm 30 and rock it clockwise, which movement is transmitted to the engaging plate 26 and, through the cam slot 25 and the stud 24, to the plate member 22, which results in the rocking of the totalizer shaft 21 counter-clockwise about the shaft 23, thereby allowing the totalizer wheels to be engaged with the adding segment 54 (FIG. 8) in the amount bank.

Clockwise rotation of the arm 31 results in the disengagement of the totalizer wheels 20 from the adding segment 54. As disclosed fully in the previously cited co-pending United States patent application of Krause and Rindfuesser, the selecting disk 50 (FIGS. 3 and 5) is controlled by a detect 55 and a finger member 56 operated by certain of the transaction keys during a machine operation. Thus, during at add, sub-total, or total operation, the selecting disk 50 is rotated to position one of the control surfaces 51, 52 adjacent a stud 49 mounted on the sensing arm 46, which will control the timing of the engaging of the three totalizer lines of the machine with the adding segmens 54 in the amount banks. The cam plates 42 will rock the driving arms 31 clockwise to engage the totalizer wheels with the adding segments between I50 and 180 of revolution of the cam shaft 43 and between 320 and 350 of the cam shaft revolution. The driving arm 31 will be rocked counter-clockwise to disengage the totalizer wheels between 270 and 300 and between and of the cam shaft revolution. Depending on what transaction key has been depressed determines the timing of the engagement of the totalizer wheels under the control of the driving arms 31. Thus, in a sub-total operation, the totalizer wheels are disengaged and then reengaged during the first of revolution of the cam shaft 43 and are then disengaged and then re-engaged during the second half of the cam shaft revolution. Reference should be made to the previously cited copending United States patent application of Krause and Rindfuesser for a full disclosure of the timing operation of the totalizer-engaging mechanism disclosed in FIG. 1

As shown in FIG. 1, each totalizer wheel has a wide tooth 57 (FIG. 6) mounted thereon. Positioned in the plane of rotation (FIG. 7) of the wide tooth 57 is a projection 58 of a tens transfer pawl 60 rotatably mounted on the shaft 23. There is one tens transfer pawl 60 for each totalizer wheel 20. When the totalizer wheel 20 is rotated by the adding segment 54 in a manner well known in the art, so that the totalizer wheel passes from nine" to zero" in a clockwise direction as viewed in FIG. 1, the wide tooth 57 will engage the projection 58 and rock the transfer pawl 60 counter-clockwise about the shaft 23. A stud 61, mounted on the pawl 60, extends into a lower notch 62 of a retaining and restoring pawl 63 rotatably mounted on the shaft 21. The stud 61 is positioned in the notch 62 when the transfer pawl 60 has not been tripped by the wide tooth 57.

The transfer pawl 60 has an extension 64, which in the untripped position is positioned adjacent a tooth portion 65 (FIG. 1) of the next-higher-order tens transfer segment 66, which in turn is mounted on a shaft 67 secured between a pair of support plates 68, which are rotatably mounted on the shaft 23. The pawl 63 has an upper notch 70, into which the stud 61 is positioned whenever the pawl 60 is tripped by the wide tooth 57. A spring 71, mounted between a bent-over ear 72 of the pawl 63 and a bent-over car 73 of the pawl 60, normally urges the stud 61 into one of the

notches

62, 70 of the pawl 63. The pawl 63 also has a foot portion 74, which is positioned adjacent the next-highestorder transfer segment 66, the foot portion 74 being moved into the path of movement of the segment 66 upon the tripping of the pawl 63 by the wide tooth 57.

Each of the tens transfer segments 66 (FIGS. 1 and 6) has a surface portion 75, which is urged into engagement with a bail member 76 by means of a spring 77 secured between a stud 78, mounted on the segment 66, and the shaft 23. The bail member 76 is rotatably mounted on the shaft 67. Secured to the right-hand portion of the bail member 76 is a stud 80 (FIGS. 1 and 4), on which is mounted a release lever 81 having a stud 82, which extends to a position engaging either an upper notch 83 or a lower notch 84 in the right-hand support plate 68. The stud 82 is urged into engagement with the notches by a spring 85, mounted between the stud 82 and a stud 86, mounted on the plate 68.

As shown in FIGS. 1 and 4, mounted on the righthand support plate 68 is a roll member 87, to which is rotatably mounted an operating member 88. The end of the roll member 87 is positioned within a portion of the cam slot 25 in the engaging plate 26. As will be described more fully hereinafter, whenever the engaging plate 26 is rocked clockwise about the shaft 27, the cam slot 25, acting on the roll member 87, rocks the support plate 68 and the shaft 67 about the shaft 23, which controls the shifting of the transfer segment 66. This movement of the engaging plate 26 is also transmitted through a stud 90, mounted on the operating member 88, to the operating member. The operating member 88 will be rocked at the end of the movement of the plate 26. A stud 91, mounted on the operating member 88, engages the release lever 81 when the member 88 is rocked counter-clockwise by the movement of the engaging plate 26.

There will now be described an operation of the tens transfer mechanism with respect to two consecutive add operations followed by a total-taking operation. As is well known in the art, the first add operation is initiated by depression of the add transaction key (not shown) after the appropriate amount keys have been depressed. As is disclosed fully in the previously cited co-pending United States patent application of Krause and Rindfuesser, the detent 55 (FIG. 5) will not move, and the selecting disk 50 will present a high surface 51 (FIG. 3) to the stud 49 of the sensing arm 46, thus preventing the rod 44 from actuating the operating plate 30. During the first half of the revolution of the cam shaft 43, the adding segments 54 (FIG. 8) are restored to their zero position. At the beginning of the second half of rotation ([80" to 255) of the cam shaft 43, the amount rack members (not shown) are differentially set by engaging the stem of the amount keys in a manner well known in the art. This operation also sets the adding segments accordingly. At 245, the

finger member 56 (FIG. 5) is rocked to engage a stud 92 mounted on the selecting disk 50, thereby rotating the disk counter-clockwise to position a low control surface 52 to the stud 49 on the sensing arm 46, thus allowing the spring 77 to move the lower stop portion 53 of the arm 46 to a position engaging the rod 44. At 320, the cam plates 42 (FIG. 2) rock the driving arms 31 clockwise, thereby allowing the rod 44 to also rock the operating plate 30 (FIG. 1) clockwise. This movement is transmitted to the engaging plate 26, whose clockwise rotation rocks the plate members 22, by means of the roller stud 24, counter-clockwise about the shaft 23 to engage the totalizer wheels with the adding segments 54.

This clockwise movement of the plate 26 also causes, by means of the cam slot 25 and the roll member 87, the rocking of the support plate 68 counter-clockwise and then clockwise about the shaft 23, thereby engaging (FIG. 15) and disengaging (FIG. 17) the transfer segments 66 and the totalizer wheels 20. This action also occurs during the clockwise movement of the plate 26 during the disengagement of the totalizer wheels from the adding segments. During this engaging movement, a lower notch 93 of the transfer segment 66 is engaged with a fixed aligning bar 94 (FIGS. 1, 6, and 15) while also engaged with the totalizer wheels. Thus the totalizer wheels 20 (FIG. 15) are in alignment during their initial engagement with the actuators. As the right-hand support plate 68 is rocked counterclockwise about the shaft 67, the stud 82 on the release lever 81 is freed from engagement with the lower notch 84 in the support plate 68 and, under the urging of the spring 85, is moved into the upper notch 83, so that, during the clockwise movement of the plate 68, the surface 95 of the release lever 81 is positioned beneath the stud 91 on the operating member 88. Thus, at the end of the first cycle of operation of the cam shaft 43, the totalizer wheels 20 (FIG. 15) are engaged with the adjusted adding segments 54.

As fully described in the previously cited co-pending United States patent application of Krause and Rindfuesser, the completion of the adding operation occurs during the first part of the next succeeding machine operation, during which time the rack members in the amount banks are returned to their home position, which action adds the amount in the totalizer wheels in a manner well known in the art. To initiate the next add operation, the operator will index the new amounts into the amount keys and depress the add transaction key, which will start the next machine operation. Between 2.5 and 40 of this second machine cycle, the driving arm 31 will complete its clockwise movement to cause a lower shoulder 96 (FIG. 1) of the totalizer engaging plate 26 to engage the stud 80 mounted on the righthand side of the bail 76, thereby rocking the bail clockwise about the shaft 67. This clockwise movement of the bail engages the surface of the transfer segments 66, rocking said segments clockwise about the shaft 67 against the action of the spring 77 (FIG. 8). During this time, the adding segments 54 are rotated counter-clockwise to their zero position, thus rotating the totalizer wheels 20 clockwise, thereby adding the amount into the totalizer wheels. As is well known in the art, the extent to which each totalizer wheel 20 is rotated clockwise by movement of its adding segment 54 to zero position is determined by the setting of the adding segment. Since all of the totalizer wheels were positioned at zero at the commencement of the first machine operation, rotation of the totalizer wheels 20 is ineffective to trip any of the tens transfer mechanisms, which would normally occur at this time.

Between 80 and 115 of rotation of the main cam shaft 43 in the second machine cycle, the driving arm 31 (FIG. 1) rocks the operating late 30 counterclockwise, which disengages the totalizer wheels 20 from the adding segments 54 (FIG. 14). Before the totalizer wheels are disengaged from the adding segments, the transfer segments 66 are rocked counterclockwise into engagement with the totalizer wheels 20 and the aligning bar 94 (FIG. 10) and are then rocked, together with the totalizer wheels 20, clockwise about the shaft 23 (FIG. 12) but with the bail 76 in engagement with the segment 66 (FIG. 14). As the engaging plate 26 (FIG. 1) completes its counter-clockwise movement, the stud 90, located on the operating member 88, is engaged by the upper shoulder 89 of the plate 26, thereby rocking the operating member 88 counter-clockwise about the roll member 87. This movement is transmitted by the stud 91 to the release lever 81, which is rocked clockwise about the stud 80, thereby camming the stud 82 from the upper notch 83 to the lower notch 84 of the support plate 68. This action rocks the bail 76 counter-clockwise from engagement with the transfer segment 66 (FIG. 12), which releases the segment 66 to the action of the spring 77. At this time, the transfer segments 66 are held by the extension 64 of the transfer pawls 60 which have not been tripped by the wide tooth 57 of the associated totalizer wheels 20. Thus no transfers are effected, and, when the transfer segments 66 are again rocked into engagement with the aligning bar 94 (FIG. 16), as will be described hereinafter with respect to a total-taking operation, the upper notch 97 of the segment will be engaged with the bar.

Between 180 and 260 of revolution of the cam shaft, the rack members in each of the amount banks and their associated adding segments are again differentially set in accordance with the amount set up by the depressed amount keys at the commencement of the second machine cycle. As described previously, with respect to the first add operation, between 320 and 350, the totalizer wheels 20 (FIG. 1), under the control of the driving arm 31 and the operating plate 30, are rocked into engagement with the adding segments 54 (FIG. 12), with the transfer segment 66 held by the extension 64 of the transfer pawl 60 against the action of the spring 7 7.

At the beginning of the third machine cycle, the operator depresses the Total transaction key on the keyboard of the machine, which initiates a machine operation. Between 2.5 and 40 of rotation of the main cam shaft, the bail 76 is rocked clockwise about the shaft 67 to normally restore the transfer segment 66, which would have been tripped during a previous transfer operation. At this time, since there was no previous transfer operation, the segments 66 have been held by the extension 64 of the pawl 60, as described previously. The clockwise rotation of the bail 76 will now engage the segments 66 against the action of the spring 77 (FIG. 8). Between 0 and 75, the rack membets and the adding segments 54 will be moved to their zero position, which action adds the amount set up in the amount banks during the second machine operation to the amount transferred to the totalizer wheels during the second machine operation. It is at this time that the primary and secondary tens transfer operation will occur.

In order to describe the operation of the tens transfer mechanism, it is to be assumed that, in one of the amount banks, an amount has been entered into the totalizer wheels which, when added to the amounts now being entered, will cause the respective totalizer wheels to pass from nine" to "zero" during the entry of the second amount and thereby trip the tens transfer pawl 60 associated with said amount bank. It is also assumed that the next higher denominational order totalizer wheel is standing at nine" and will not receive an entry from its adding segment.

As the adding segment 54 (FIGS. 8 and 9) moves counterclockwise towards its home position, the engaged totalizer wheel 20 is rotated clockwise (FIG. 9) and, as described above, will pass from the nine position to the zero position. As this occurs, the wide tooth 57 engages the projection 58 of the transfer pawl 60, rocking the pawl counter-clockwise about the shaft 23. This action trips the pawl. The counter-clockwise movement of the pawl 60 removes the stud 61 from the lower notch 62 (FIG. 6) of the restoring pawl 63 to the upper notch by the action of the spring 71. This movement positions the foot portion 74 of the pawl 63 in the path of the counter-clockwise rotation of the tooth portion 65 of the transfer segment 66 in the nexthighest denominational amount bank. The counterclockwise movement of the pawl 60 also moves its extension 64 from out of the path of the segment 66 in the next-highest denominational amount bank.

Between and l l5 of revolution of the cam shaft 43, the shaft 67 (FIG. 11) is rocked counter-clockwise about the shaft 23 in the manner described previously, thereby bringing the transfer segment 66 into engagement with the totalizer wheels 20. Then both the totalizer wheels 20 and the engaged segment 66 are rocked clockwise about the shaft 23, thereby disengaging the totalizer wheels 20 from the adding segments 54 (FIG. 13). During this time, the bail 76 is rocked counterclockwise about the shaft 67, thereby releasing the next-higher-order segment 66 to the action of the spring 77 (FIG. 13). The spring 77 rotates the segments 66 counter-clockwise (FIG. 24) about the shaft 67 which rotates the engaged totalizer wheel 20 in the next-higher amount bank clockwise about the shaft 21. The segment 66 moves counter-clockwise until it engages the bail 76, which movement is the equivalent of one tooth space of the totalizer wheel 20. Thus a tens transfer is effected into the next-higher denominational order (FIG. 14). The counter-clockwise rotation of the segment 66 also causes its tooth portion 65 to engage the foot portion 74 of the restoring pawl 63, rocking the pawl clockwise about the shaft 21, thus restoring the stud 61 of the transfer pawl 60 to the lower notch 62 of the pawl 63 by the action of the spring 71.

As was described above, the next-higher-order totalizer wheel 20 was assumed to be standing in the nine" position prior to the primary transfer operation, which operation caused it to move from nine" to zero,

thus tripping its transfer pawl 60 in the manner described previously. Since at this time the bail 76 is not engaged with the transfer segment 66, which is now being held by the extension 64 of the transfer pawl 60 (FIG. 12), the tripping of the transfer pawl 60 releases the segment to add one unit into the totalizer wheel of the next-higher-order amount bank due to removal of the extension 64 from engagement with the segment 66. Thus both the primary and secondary transfer operations will have occurred by l50 of revolution of the cam shaft 43.

As disclosed fully in the previously cited co-pending United States patent application of Krause and Rindfuesser, in a total-taking operation, the driving arm 3] will pick up and rock the operating plate 30 and the totalizer-engaging mechanism clockwise between 150 and 180 of the revolution of the cam shafi, which moves the totalizer wheels 20 into engagement with the adding segments 54, which are now standing in their zero position. Between 180 and 260, the rack members of the amount bank and their associated adding segments will then move, which will rotate the totalizer wheels counter-clockwise (FIG. 15) about the shafl 21 until the wide tooth 57 engages the projection 58 on the transfer pawl 60. This engagement arrests the rack member and the adding segments 54 in positions corresponding to the total amount entered into the totalizer wheel. Between 270 and 300, the driving arm 31 is rocked counter-clockwise to disengage the totalizer wheels 20, which now stand at zero, from the adding segments 54. During this time, the transfer segment 66 and the shaft 67 are rocked clockwise about the shaft 23, thereby disengaging the segment 66 from the totalizer wheels (FIG. 17). As disclosed previously, between 0 and 75 of the next machine operation, the adding segments are returned to their zero position while the bail 76 is rocked clockwise (FIG. 8) about the shaft 67 to restore all of the tripped transfer segments 66 as described previously. it will thus be seen that, with this tens transfer construction, the total operation of a machine can occur during a single machine operation in which both primary and secondary transfer operations are concluded and while allows the restoration of the transfer segments to occur without interfering with the machine operation.

What is claimed is:

l. [n a cash register having a plurality of amount banks of keys each of which includes a differentially settable actuator mechanism settable to a position representing amounts set up in the amount banks, a tens transfer mechanism for effecting primary and secondary transfers simultaneously which includes a. a totalizer wheel rotatably mounted in each amount bank and adapted to be moved between an engaged position and a disengaged position with said differentially settable actuator mechanism;
