8 Claims.

This invention relates to repeat mechanism for cash registers and the like, but more particularly to repeat mechanism for the type of machine shown and described in the co-pending application for United States Letters Patent, Serial Number 172,660, led March 4, 1927, by William H. Robertson, which issued into Patent No. 1,924,- 290 on August 29, 1933, of which this application is a division.

One object of this invention is to provide a machine having a plurality of totalizers with means for transferring a total from one totalizer to another subsequently to the totalizing operation and without knowledge that such total is to be transferred. Another object is to provide means whereby a total may be reentered in the totaliser :from which it was taken after said totalizer has been returned to zero.

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

GENERAL DESCRIPTION The machine in which the present invention is embodied is provided with four banks of amount keys and one bank of transaction keys. The instant machine is also provided with a plurality of totalzers, each of which may be selected by a lever situated at the front oi the machine. A manipulative member commonly called a total lever is provided for controlling the various functions of the totalizers. The instant machine is provided with both electrical and manual means of operation, and may be released for either electrical or manual operation by means of a starting bar conveniently located on the keyboard.

A repeat release key is also provided in the instant machine for use when it is desired to duplicate preceding transactions. The repeat release key may also be used for transfering amounts from one totalizer to another and for re-entering totals in a totalizer which had been cleared by the preceding operation.

In the following description the above mechanism pertinent to the instant invention will be described in detail:

DE'nAILED DESCRIPTION Amount banks The machine of the instant invention is provided With four banks oi amount keys 5Fl (Figs. l and 2) slidably mounted in key frames 5l supported on rods 52 and 53 carried in the side frames Ed and 55 (Figs. 2, '7 and 9). Each key 5D is held in its outer or normal position by a coil spring 56 (Fig 2). Each bank is provided with a exible detent 5l which cooperates with a stud Eil secured in each key 59. The depression of a key shifts the detent 5l downwardly against the tension of a spring 59 until the stud lit passes the shoulder on the detent 5l whereupon the spring 59 shifts the detent upwardly to hold the key in its depressed position.

Each key bank is also provided with a locking bar 6U (Fig. 2) which upon release of the machine is moved upwardly by mechanism to be hereinafter described, thereby moving said locking bar 50 beneath the studs 58 of the undepressed keys and over the stud 58 of the depressed key, thus locking the undepressed keys in their outer positions and the depressed key in its inner position. The exible detent 51 and the locking bar 65 are slidably mounted on two studs 6| (Fig. 2) secured to the key frame 5|.

Each bank of amount keys is provided with a Zero stop pawl 52 (Fig. 2) for controlling the differential mechanism, to be later described, when no key is depressed in the bank. The pawl 62 is rocked to its ineffective position by a stud 63 carried by the detent 51 when any key is depressed in the associated amount banks. Depression of a key lowers the detent 51 as above described, thereby rocking the zero stop pawl 62 clockwise by engagement of the stud 63 with the shoulder Bil on the zero stop pawl 62. The Zero stop pawl is pivoted on a stud B5 (Fig. 2) on the key frame 5| and held in engagement with the stud |53 at all times by a spring 65.

Transaction bank The transaction bank of keys 69 (Fig. 1) is of the same construction as the amount banks. These keys are used for printing identication characters and indicating the kind of transaction entered in the machine.

Operating mechanism After the operator has depressed the desired key representing the transaction, he may operate the machine either by means of a crank 15 (Fig. 1) or by an electric motor (not shown). The motor is located beneath the registering mechanism and access thereto may be had through a door 14 in the front of the cabinet. Depression of the motor bar 16 releases the clutch mechanism and closes the circuit through the motor. Such mechanism is shown and described in United States Letters Patent to Kettering and Chryst No. 1,144,418 dated June 29, 1915.

The machine is operated by means of a main cam shaft S5 (Figs. 3 and 9) which receives one complete revolution for each machine operation. Rotation of the cam shaft 8|! is effected by a train of mechanism including pinion 8|, pinions 82 and 83 secured together and mounted on a stud 84, and pinion secured to worm gear 86 which meshes with a worm gear 81 on the main cam shaft 85. The pinion 3| is secured by a sleeve to one member of the motor clutch mechanism above referred to. The motor clutch is driven by a pinion (not shown) on the motor armature which meshes with a gear secured to a bevel pinion (neither of which is here shown). The bevel pinion meshes with a bevel gear 9| (Fig. 3) secured to one member of the motor clutch mechanisrn. T/Vhen the motor is released the clutch drives the pinion Si and through the train of pinions and gears 82, S3, 85, 86 and 81', causes the main cam shaft 8|) to receive one complete rotation.

When the machine is operated by the crank 15 (Fig. 1) the main cam shaft 8|) is given one complete rotation by means of a train of gears, not here shown, but fully illustrated and described in the parent application above referred to.

Machine releasing mechanism The machine is released for operation by depression of the motor bar 1B (Fig. 3) The motor bar 16 is removably mounted on a plate ||6 slidably mounted on the right frame 55 and normally retained in its upward position by a spring H1. The plate IB carries a stud l l5 adapted to cooperate With a pivotally mounted pawl H5. Depression of the motor bar 15 withdraws the pawl H4 from beneath a flange H3 on a slidably mounted link ||0 and permits a spring (not shown) to lower the link il). Downward movement of the link lill rocks an arm |54 outwardly (Fig. 3) to withdraw said arm from the path of the driven member of the clutch mechanism, thereby permitting the machine to begin an operation.

This release of the clutch mechanism also closes a circuit through the electric motor, causing it to operate. The mechanism for closing the circuit through the motor is Well known in the art and is illustrated and described in the above mentioned Kettering and Chryst patent.

The link IIS) is restored to its normal position upward near the end of the operation of the machine, and the arm |54 rocks into the path of the clutch mechanism, thereby stopping the machine by mechanism not here shown but fully illustrated and described in the above referred to parent application.

The well known non-repeat pawl |22 (Fig. 3) is provided for preventing a second operation of the machine in case the motor bar 16 is not permitted to return to its normal position before the end of the operation of the machine. If the operator should hold the motor bar in its depressed position as the machine completes its operation, the non-repeat pawl |22 moves beneath the iiange i i3 under tension of a spring 623, which normally holds the pawl |22 engaged with a flange |24 of the release pawl lill. The operation of this nonrepeat mechanism is well known in the art and it is felt that further description is unnecessary.

Locking bar operating means As above mentioned, each bank of keys is provided with one of the locking bars 65 (Fig. 2) which is rocked beneath the stud 53 of the undepressed amount keys and abovethe studs 58 of the depressed amount keys, thereby preventing depression of a key or the release of a depressed key after the machine has been released for operation.

Mechanism for operating this locking bar is under control of the link li). The link IIS (Fig. 3) has secured thereto a stud B55 embraced by a bifurcated arm |56 of a yoke |51 (see also Fig. 8) extending between the side frames 54 and 55. Each locking bar GU is provided with a stud |58 (Fig. 2) which projects into a bifurcated arm |59 loosely mounted on a shaft |60 carried by the side frames. The downward movement of the link upon releasing the machine, as above described, rocks the yoke |51 clockwise to engage and rock the arm |59 counterclockwise, which by means of the stud |58 raises all the locking bars 5l) into locking position.

The yoke |51 (Fig. 8) is provided with an arm |63 (Figs. '7 and 8) for preventing operation of a repeat release key |64 after the machine has been released. The repeat release key is mounted on a rod 2 I5 supported in the side frames 55 and 55. The repeat release key and its associated mechanism will be described hereinafter.

Restoration of the link H5 to home position near the end of machine operation, as hereinbefore described, returns the yoke |51 to its normal position thereby permitting the locking bars 60 land arms I 59 to be returned to their normal positions by a spring |68 (Fig. 2). However, if for some reason the above parts should not be restored by the springs |68 the key releasing mechanism to be presently described, positively restores the locking bars and the arms |59 to their home or normal positions.

Key release mechanism Mechanism has been provided for automatically releasing the depressed amount and transaction keys at the end of machine operation. Near the end of machine operation the shaft |69 (Fig. 2) is rocked clockwise by mechanism not here shown, but fully illustrated and described in the parent application referred to hereinbefore. This causes an arm lll secured to the shaft |60 to lower the flexible detent 51 thereby disengaging the hook on said flexible detent from the stud 53 in the depressed amount key, whereupon the depressed amount key is returned to home position by its spring 56. Clockwise rocking of the shaft |69 also causes the arms I'H to engage a stud |85 in the arms |59 to positively return the locking bars 59 to their normal ineffective positions.

Manual means have also been provided for rocking the shaft |60 clockwise to release the depressed amount and transaction keys. Such manual releasing mechanism is not here shown, but reference may be had to the parent application for a full description thereof.

Differential mechanism The differential mechanism for all the amount banks is identical. Therefore the differential mechanism for one amount bank only will be described herein. The differential actuator is adjusted under the influence of a spring, the differential movement thereof being controlled by the lower end of the depressed amount key.

Referring to Fig. 2, a shaft 2|5 journaled in the frames 54 and 55 has pivoted thereon an actuator 2|() provided with teeth 2H and a forwardly extending arm 218. A spring 229 is tensioned to rock the actuator 246 in a clockwise directicn, but is prevented from doing so by a Universal rod 22| (Figs. 2 and 6) carried by a pair of arms 222, only one of which is shown (Fig. 6) secured to the shaft 2 I5. One of these arms (Fig. 6) is adjacent the left side frame 54 and the other arm 222 is located adjacent the right side frame 55. Secured to the left-hand arm 222 (Fig. 6) is a disk 223 having gear teeth which mesh 7 with a segment 224 pivoted on a stud 225 carried by the left frame 54. The segment 224 has mounted thereon a pair of rollers 226 which coopera-te with a pair of cam plates 22'!v secured to the main cam shaft 8|).

When the cam shaft 80 rotates during the machine operation the segment 224 rocks the arms 222 and the rod 22| lrst in a clockwise direction (Fig. 6) thereby permitting the actuator 2|5 (Fig. 2) to be rocked under the influence of the spring 222 until stopped by the end of the depressed key 50, unless prevent-ed from moving by the zero stop pawl 52 (Fig. 2). The rod 22| advances far enough to permit nine steps of movement of the actuator 2|6.

After the actuator 2|6 has been positioned under control of one of the keys 5U and the rod 226 has finished its clockwise movement a totalizer pinion 239 (Fig. 2) is moved into mesh therewith in a manner to be hereinafter described. After the totalizer pinion has been engaged with the actuator 2|6. the segment 224 (Fig. 6) is rocked counterclockwise by the cams 227 thereby moving the rod 22| back to its normal position to carry the actuators 2|@ back to home position. This backward movement of the actuator 2M adds an amount on the totalizer pinion commensurate with the value of the amount key depressed.

A stop is provided to prevent overthrow of the arms 222 and the Universal rod 22| (Fig. 6). The arm 222 which is adjacent the left frame 5i) is provided with surfaces 231i and 239 which engage a stud 232 when said arm 222 is rocked to its extreme positions. Thus the stud 292 limits the movement of the arm 222 and the rod 22! in both directions.

Transaction bank dijjerentz'al mechanism An actuator 255 is also provided for the transaction bank, but this actuator is only used for adjusting the type carriers and indicators in a manner to be later described. There is no totalizer pinion 2322 associated with the transaction bank.

Totalizers The machine of the instant invention is provided with two interspersed totalizers, each consisting of a set of pinions 232 (Fig. 9). A mechanism to be presently described, is provided for shifting the two sets of pinions 239 into operative alinement with the actuators M5. The totalizer pinions 2.3i), rotatably mounted upon a sleeve 259 (Figs. 2, 9 and l0) are properly spaced thereon by collars 219. The sleeve 259 is slidably mounted on a shaft 295i) supported by two arms 26| to a shaft 262 journaled in the frames 52 and Secured to the shaft 252 is an arm 263 (Figs. 3 and 9) having pivoted thereto a link 22d. The link 264 carries a stud 'H3G adapted to cooperate with a bifurcated arm 229 pivoted tothe frame The arm F29 has a cam slot 'E28 through which projects a stud mi fast in the total lever 92. As the total lever is moved to the Add position the stud i271 cooperating with the cam slot 728 rocks the arm 729 causing a stud 225 in the link 254i to engage a notch 285 (see also Fig. 4) in an arm 25'! during adding operations. The arm 29? (Fig. 4) is provided with a roller 26d which projects into a cam slot in a cam disk 2F59. The cam slot in the disk 289 is so timed that during the operation of the machine the totalizer pnions 23) are engaged and disengaged from the actuators 2id at the proper time.

Alining devices, including an arm 275 and an aliner 212 (Fig. 2) are provided for maintaining the totalizer pinions in proper alinement when disengaged from the actuators Zi. These parts are sol arranged that the aiiner becomes disengaged at the time the tctalizer pinions begin to engage the actuator 2li?, and becomes ire-engaged just before the totalizer pinions are entirely engaged from the actuators, all of which is fully explained in the parent application above referred to.

Alining means is also provided for holding the totaliZer pinions 239 of the totalizer which is not in operative alinenient with the actuators 2 i 5 against rotation. This means consists of a bar 225 (Figs. 2 and 9) slotted to permit free rotan tion of the pinions of the totalizer in operative alincment with the actuator 2 i5.

Transfer mechanism A transfer mechanism has been provided for the totalizers for carrying l to the next higher order pinion when the lower order pinion passes from 9 to 0. It is felt that a description of the above transfer mechanism is unnecessary herein, as reference may be had to the Robertson application, Serial Number 172,660, of which the present application is a division, for a full description of the transfer mechanism.

Totalzzer selecting means Means have been provided for selectively shifting the pinions of the desired totalizer into operative alinement with the actuators 2&6 and such means will now be explained. The sleeve 259 (Figs. 9 and 10), which as before stated, carries the two sets of totalizer pinions 232, is shifted by a manually operable lever 3|!! (Figs. l, 3, 9 and l0). The righthand end of the sleeve 259 has secured thereto a collar 32|) (Figs. 9, l0 and 11) engaged by an upwardly extending arm 32| of a totalizer selecting slide 322 slidably mounted on a crossbar 23| supported between the frames 54 and 55. The slide 322 is provided with a rack 323 (Fig. 1l) which meshes with a pinion 324 secured to a shaft 325, the forward end of which is journaled in the bar 28| and the rearward end in the back frame 24|. Secured to the shaft 325 is an arm 326 (Figs. 3 and 9) having forwardly extending flanges 321, adapted to be pivoted to rearwardly extending flanges 328 on the lever 3|2 to form a connection between the lever 3|9 and the shaft 325.

The lever 3|9 has a finger 330 (Figs. 3 and 10) adapted to cooperate with notches 33| in a plate 332 secured to the crossbar 28|. The lower end of the lever 3|3 is adapted to cooperate with a flange 233 of an arm 333 secured to an arm 334 by a hub loosely mounted on a stud 335 secured in the frame 55. A spring 333 (Fig. 3) is tensioned to rock the arms 334 and 338 clockwise.

When it is desired to select the totalizer, the upper end of the lever 3|!! (Figs. 3 and l0) is first pressed rearwardly against the tension of the spring 333 until the finger 33|] is withdrawn from the notch 33|. This frees the lever 3|9 so that it may be rocked either to the right or to the left, as the case may be. Rocking of the lever 243 through the shaft 325, (Fig. ll) pinion 324 and rack 323, shifts the totalizer selecting slide 322 to move the desired totalizer into position to be engaged with the actuators. The selected totalizer is retained in alignment with the actuators by means of aligning notches 34B (Fig. 9) in the slide 322 being engaged by aligning teeth 534i on the arm 253 whenv the latter is rocked to engage the totalizer with the actuators.

An interlock is provided between the lever 3|9 and the machine releasing mechanism which prevents release of the machine when the lever 3|9 is out of effective position, and locks the lever 3l2 in effective position after the machine has been released. Pressing the lever 3|9 rearwardly, preparatory to shifting the totalizer, rocks the arm 334 (Fig. 3) counterclockwise until its upper end is in the path of a stud 342 in the link H2. This prevents releasing of the machine by holding the link Ilfl' in ineffective position until the lever 3MB is moved into an effective position. Likewise releasing of the machine for an operation lowers the link lll), causing the stud 342 to move into the path of the arm 334 to lock the lever 3 il in effective position during machine operation.

Indicators Calling attention to Figs. 1 and 2, the machine is provided with a series of indicators 422, one for each amount bank and one for the transaction bank. These indicators are first restored to zero and then set up according to the amount of differential movement given the totalizer actuators 2 I 6 during machine operation.

For each indicator there is a segment 42| (Fig. 2) loosely mounted on the shaft 2|5, and meshing with a gear 422. One of the gears 422 is secured to the end of a shaft 423 and one is secured to each of the sleeves 424. Each gear 422 meshes with a gear 425 loosely mounted on a rod 426 carried by the side frames 54 and 55. The gears 425 mesh with pinions 42T secured to the indicators 42B. When the rod 22| (Fig. 2) moves forwardly to allow setting of the actuators 2|6, it contacts a surface 429 on the segment 42| and moves said segment far enough clockwise to return the indicators 420 to their Zero positions. The gears 425 are stopped in Zero positions by a rod 430, which passes through slots out in said gears 425 and acts as a positive zero stop for the indicators 420.

A coupling pinion 440 (Figs. 2 and 7) is provided for each differential mechanism for coupling the actuators 2|6 with the segments 42|. The coupling pinion 44B is normally in mesh with the actuators 2l6 and the segments 42|, but at the beginning of the machine operation said pinions are moved out of mesh long enough to permit the actuators 2|5 to be adjusted under control of the depressed amount keys 50 and also for permitting the rod 22| to restore the segments 42| to zero, as above described. After the actuators 2|6 have been adjusted the coupling pinions 440 are again moved into mesh and the actuators are returned to their home positions. Such movements of the actuators is transmitted to the indicators 420 by the segments 42| and the train of gears above described. Thus the indicators are set commensurate with the value of the amount keys depressed.

The coupling pinions 446' (Fig. 2) are all loosely mounted on a rod 44| (see also Fig. 7) carried by two arms 442 secured to a shaft 443 journaled in the frames 54 and 55. Also secured to the shaft 443 is an arm 444 carrying a stud 445 embraced by a notch in a link 446 guided at its upper end by a stud 441 which projects into a slot in the repeat release key 64. The lower end of the link 446 is pivoted to an arm 448 secured to the shaft 2|0. Secured to the shaft 2|!) is an arm 449 (Fig. 3) provided with a roller 450 projecting into a cam groove 45| on one side of a cam 452 secured to the main cam shaft 8|).

At the beginning of an operation of the machine the cam 45| through the arm 449 rocks the shaft 2||l clockwise to lower the arm 448 (Fig. 7) and the link 446. The lowering of the link 445 rocks the armv 444 and shaft 443 counterclockwise to disengage the coupling pinions 440 from the actuators 2|6 and the segments 42|. After the actuators 2 I5 have been positioned according to the depressed amount keys and all the segments 42| have been moved to zero, the cam groove 45| through the mechanism actuated thereby moves the coupling pinions back into mesh with the actuators and segments. The rod 22| then returns the actuators to their home positions to adjust the indicators as above described.

From the above description it is apparent that at the end of the operation of the machine the indicators and the trains of mechanisms connected thereto remain set according to the previous operation. However, the actuators 2|6 are al1 returned to home positions and remain thus when the machine is idle.

Secured to the back frame 2li! is an aligner 468 (Fig. 2) adapted to cooperate with the tooth spaces of the coupling pinions 44B when said coupling pinions are disengaged from their actuators @is and the segments Ml. This retains the pinions fitti in proper alignment with said actuators 2 iii and segments 42|! so that upon subsequent reengagement they will mesh properly with each other.

Type carriers As hereinbefore mentioned the shaft 423 (Fig. 2) and each sleeve i255 has secured on their lefthand ends gears Q22, which are adjusted according to the differential movement of the actuators 264i. The righthand ends of the sleeves lit and the shaft have secured thereon gears (not shown) adapted to position a plurality of type carriers (not shown) according to the differential movement of' the actuators 2m.

Total-taking operations This machine is also capable of performing total-taking operations. The total control lever 52 (Fig. i) has four positions, namely, ad read, reset and non-add. When it is desired to read the total on a totalizer the lever is moved to the read position and the machine operated in the usual manner. However, if it is desired to read the totalizer and reset it to zero, the total lever is moved to the reset position and an operation of the machine prints the total and resets the totalizer to Zero.

Reading or sub-total operations In read operations the totalizer is rocked into engagement with the actuators 2i6 at the beginning of machine operations. Then when the Universal rod E22! (Fig. 2) is moved forwardly the totalizer pinions 235 are rotated in a backward or counterclockwise direction until the long tooth 352 on each pinion is stopped by the forward end of the associated transfer trip pawl 351i. This is the Zero position of the totalizer `pinions and the amount standing on the totalizer wheels will have been transferred to the actuators 2l. Return movement of the rod 252i causes the amount to again be added upon the totalizer wheels and the indicator and type carriers adjusted accordingly.

The cam for controlling the engagement and disengagement of the totalizer during read operations is shown in Fig. 5. In order to make this controlling cam effective it is necessary to engage the stud 265 (Fig. 3) with a notch '25 (Fig. 5) of an arm l2@ loosely mounted on the shaft 210.

As the total lever 62 (Fig. 3) is moved to the read positionthe stud I2? cooperating with the cam slot F28 rocks the arm 129, causing the stud 265 in the link 264 to engage the notch 'E25 in the arm 726.

The arm E25 (Fig. 5) is provided with a roller 'H32 which engages a cam race 133 in the lefthand side of the cam G52 mounted on the main cam shaft 8&3. The cam race 'E33 is so timed as to engage the totalizer with the actuators before the actuators move, and to disengage the totalizer after the Universal rod 22| is returned to its normal position, thus causing the amount to again be added on the totalizer, and the indicators and type carriers set up.

During totalizing operations the Zero stop pawls 62 (Fig. 2) are rocked to ineffective positions in the following manner. A stud 'M5 (Figs. 3 and 8) in the total lever l G2 is adapted to cooperate with a camming surface on the lower end of an arm 766 secured to the shaft 533 when the total lever E52 is moved to the read or reset position to rock the arm Mii and shaft 533 counterclockwise. The counterclockvvise movement of the shaft 533 causes an arm (Fig. 2) secured thereon to also rock ccunterclockwise, causing a stud 535 in the arm 535. to engage the Zero stop pawls 62 to rock them to ineffective positions during read and reset operations.

Reset or tantalizing operations A reset operation is performed in the same manner a read operation, the only difference being that the totaiizer is disengaged from the actuators l before said actuators are returned to their home positions. This prevents the amount from being re-entered in the totalizer.

Movement of the t-otal lever 62 (Fig. l) to the reset position, through the stud l2? cam slot liii and arm 'i129 (Fig. 3) causes the stud 255 to engage the bifurcated arm (its. The arm M9 is rocked by the cam race 35i in the cam Llii as before described, and the timing thereof is such that at the beginning of the machine operation the totalizer is engaged with the actuators and after being returned to zero is disengaged therefrom before the Universal rod '222i is restored to its home position. Thus it is seen that with the totalizer disengaged when the actuators 2W are restored to normal, the amount will not be reentered in the totalizei` and therefore the totalizer will be left at zero.

Repeat release lcey mechanism The repeat mechanism provided in this machine is characterized by the fact that the operator need not know at the time of making the original entry that the amount is to be repeated. Therefore an amount of a preceding transaction may be repeated at any time after said transaction. It is also possible to repeat a total operation after the totalizer from which said total was taken has been returned to zero. It is also possible by using the repeat release key to transfer a total from one totalizer to any other` totalizer after the totalizer from which the total was originally taken has been returned to zero, or if desired, the total may be re-entered in the totalizer from which it was taken.

In repeat mechanism heretofore known in'the art, it is necessary to make a preliminary setting before the original amount is entered in order that this amount may later be repeated. Such preliminary setting has been entirely done away with in the present invention. All that the operator need do is to glance at the indicators and if they show the amount which he desires to enter in the machine, he rst sees that the total lever is in the add or non-add position and then presses the repeat release key which releases the machine to enter the desired amount. It is obviously a fact that a repeat mechanism such as this is useful in a great many lines of business and it is not desired to limit its use to any particular system or systems.

It will be recalled that the segments lili at the end of machine operations (Fig. 2) are left standing in the positions to which they were adjusted under control of the depressed amount keys 5l) in add and non-add operations and under control of the long teeth on the totalizer pinions 230 in read and reset operations. It will also be remembered that the actuators 2|6 are always restored to their home or zero position. During repeat operations the segments 42| and the gears 422 and 425 together with the rod 43D are used for controlling the positioning of the actuators 2|5. As it is impossible to perform a repeat operation with any of the amount keys 50 depressed, other means must be provided for positioning `the actuators 2|6. This means consists of the rod 433 which stops the gears 425 and through the gears 422 stops the segments 42| in their Zero positions as above described.

Depression of the repeat release key |64 (Fig. '7) disconnects the link 445 from the stud 445 and therefore when the machine starts to operate the coupling pinions 445 will not be disengaged from the actuators 2|6 and the segments 42|. A slot 43| out in the lower end of the repeat release key |54 embraces the stud 445, thereby holding the arm 444 and pinions 443 in positive alinement when the repeat release key is depressed. Thus when the rod 22| (Fig. 2) receives its forward movement to restore the segments 42| to their zero positions the actuators 2|6 are moved like distances thereby setting up the actuators to the amount previously standing on the segments 42|. During the return movement of the rod 22| the coupling pinions remain engaged with the actuators and segments and therefore the actuators 2|5 are returned to their home positions and the segments 42| are returned to the positions in which they were standing at the beginning of the repeat operation.

Repeat operations may be made only when the total lever is in either the add or as shown in Fig. l, in the non-add position. With the total lever in the add position the amount previously standing on the segments 42| is again added into the pinions on the selected totalizer, and the indicators and type carriers are adjusted in the same manner as before described for adding operations.

The means for disconnecting the link 446 (Fig. 7) from the stud 445 consists of a slot in the repeat release key |64 through which the stud 441 projects. Depression of the repeat release key rocks the link 446 clockwise until it is disengaged from the stud 445.

It is not necessary to depress the motor bar 16 (Fig. 1) to release the machine for a repeat operation. Depression of the repeat release key |64 (Fig. '1) causes a stud 5||| to enter a slot 5|| in an arm 522 secured to the shaft 5|3 to rock said shaft counterclockwise. Counterclockwise movement of the shaft 5|3 (Fig. 3) causes a stud 5|5 in an arm 5|4 secured on the shaft 5|3 to engage the lower end of the release pawl ||4 to withdraw said pawl |l4 from beneath the flange v||3 on the link H0 to release the machine for operation in exactly the same manner as described hereinbefore.

A spring 5|6 (Fig. 7) is arranged so that regardless of which direction the arm 5|2 and shaft 5|3 are rocked said spring will return and retain them in normal positions. A spring 5|9 (Fig. 1) is provided for retaining the repeat release key |54 in its normal ineffective position against the stop stud 526 in the frame 54. The frame 54 also carries a stud 52| for limiting the downward movement of the repeat release key.

As the actuators 2|6 are moved under control of the segments 42| during repeat operations, it is necessary that the Zero stop pawls 52 (Fig. 2) be rocked to ineffective positions and this is accomplished in the following manner: The repeat release key |64 carries a stud 535 (Fig. '1) which when the repeat release key is depressed enters a slot 53| in an arm 532 secured to the shaft 533 to rock said shaft counterclockwise. This causes the stud 535 (Figs. 2 and 8) in the arms 534 to engage the zero stop pawls 62 and rock them to ineffective positions during repeat operations. The arm 534 is also provided with a flange 536 which is rocked into the path of a pawl 531 pivoted on the flexible detent 51. Thus when the arm 534 is rocked counterclockwise by the depression of the repeat release key the flexible detent 51 is locked against movement, which in turn locks the amount keys 5B against depression during repeat operations.

As previously set out the amount keys are released by rocking the flexible detent 51 downward, and as this detent is locked against movement during repeat operations, it is necessary that the automatic releasing mechanism for the amount keys be disabled during repeat operations. While this releasing and release disabling mechanism is not here shown, reference may be had to the parent application for a full description thereof.

Repeat release cey lockout mechanism Means is also provided for preventing operations of the repeat release key if any one of the keys in any of the amount banks has been depressed. The depression of an amount key rocks its respective flexible detent 51 (Fig. 2) downwardly, thereby positioning the pawl 531' on said detent in the path of the flange 536 on the arm 534, thus blocking the counterclockwise movement of the shaft 533 and thereby preventing depression of the repeat release key |54.

As previously stated, the yoke |51 (Fig. 7) is provided with an upwardly extending arm |63 for preventing depression of the repeat release key after the machine has been released for operation. The arm |63 is provided with a surface 542 which is rocked beneath the stud 530 on the repeat release key when the machine is released for operation by the motor bar 16, thereby locking the repeat release key |54 against depression.

The arm |63 has a recess 543 (Fig. 1) which passes over the stud 533 when the repeat release key is fully depressed, thereby permitting clockwise movement of the yoke |51 which allows the machine to release.

Interlocks When the total lever |62 (Fig. 3) is moved to read or reset position a stud 145 (Fig. 3) fast therein engages an arm 146 secured to the shaft 533, to rock said shaft counterclockwise thereby moving the flange 536 (Fig. 2) on the arm 534 beneath the pawl 531 on the exible detent 51. This locks all keys, except the transaction keys, against depression during totalizing operations. This same train of mechanism likewise prevents moving the total lever to the read or reset position when any of the amount keys 50 are depressed, as this rocks the pawl 531 into the path of the flange 536 thereby preventing counterclockwise movement of the shaft 533.

Movement of the total lever |52 (Fig, 3) to either read or reset position also locks out the repeat release key |64 in the following manner. The total lever is provided with a cam surface 180 which engages a stud 18| in the arm 5|4 when the total lever is moved to read or reset position. This movement of the arm 5|4 rocks the shaft 5|3 and the arm 5|2 clockwise thereby positioning the locking surface 522 (Figs. 'l and 8) beneath the stud 5l@ on the repeat release key to prevent depression thereof.

Means are also provided for locking the machine against release when the total lever H52 is not properly adjusted in one of its four positions. Such locking mechanism, While not here shown, is fully illustrated and described in the parent application.

Transfer totals Totals may be transferred from one totalizer to another any time after a read or reset totaltaking operation is completed. No preliminary setting is necessary. Thus the totals can be tran.,- ferred even though the operator does not know at the time of making the read or total-taking operation that such total is to be transferred.

The transferring of a total is effected by the repeat release key 64. In transferring a total from one totalizer to another all the operator need do is to make a total or sub-total operation, then position the selecting lever 3l@ (Fig. 10) to select another totalizer and depress the repeat release key whereupon such total or subtotal, as the case may be, is transferred into the selected totalizer.

During any total-taking operation the segments @2l are adjusted to represent the amount standing on the totalizer. Upon subsequent depression of the repeat release key the actuators ZIB are controlled in the same manner as described for repeat operations and therefore it can be seen that the amount taken from the totalizer will be added into the subsequently selected totalizer,

If after a reset operation it is desired to reenter the total on the totalizer, this may be done by the repeat mechanism. At the end of a reset operation, the amount taken from the totalizer remains in the segment @El and therefore in order to reenter this amount all that is necessary is to move the total lever to the add position and press the repeat release key. During this operation the segments 42! (Fig. 2) control the differential positioning of the actuators 2id in the same manner as previously described for adding repeat operations.

In View of the foregoing description it is felt that a statement of the operation and use of the machine is unnecessary. However, a brief summary will be given of the functions of the machine.

The machine of the instant invention is provided With two totalizers, either of which may be selected for adding, reading or resetting by means of the totalizer selecting lever Sii) and the total lever |52. The totals standing on the totalizers may be read and re-entered in the totalizers, or the totals may be read and the totalizers reset to zero. This is controlled by the total lever IGZ which has four positions of adjustment, namely, non-add, add, read and reset, When the total lever is in the non-add position the depressed amount keys Sil serve only to position the indicators and the type carriers. When the repeat release key is used with the total lever in non-add position the indication andprinting of the amount of the preceding transaction is duplicated.

A total may be taken from either totalizer and transferred to the other. This operation consists of taking a total in the ordinary way selecting the desired totalizer and then depressing the repeat release key. This mechanism is also useful when the operator makes a reset operation by mistake, as he may re-enter the amount on the cleared totalizer by depressing the repeat release key.
