(Cl. y23S-59) 4 Claims.

This invention relates to accounting machines and moreparticularly to machines having column registers in which numbers are entered digit by digit and 'a crossfooter, or cross computing register arranged to be actuated to correspond with the actuation of the registers. The invention is shown as embodied in a typewriting and accounting machine of the Elliott-Fisher type.

In crossfooters of the usual construction employed in machines of the above type, the transfer mechanisms for the respective trains of accumulator wheels of the crossfooter are tripped in succession assaidtrains are actuated in succession by the master wheel of the crossfooter. This master Wheel moves step by step across the several trains of the crossfooter to correspond with the movement of the master wheel which operates the column registers, across said registers. The transfer mechanisms remain in tripped position until the end of the register and crossfooter actuation and,I must berestored to operating positions before another accumulating operation of the crossfooter.

The primary object of the present invention is to provide accounting machines of the type in which numbers are entered digit by digit in the registers and crossfooters with noveland improved mechanism for resetting the transfer mechanism of the crossfooter by power.

With the abovekobject in view, the` invention consists in a transfer resetting mechanism for the crossfooter embodying the novel rand improved features, constructions and combinations of parts hereinafter described and particularly pointed out in the claims, the advantages of which will be readily understood and appreciated by those skilled in the art.

The invention will be clearly understood from the' accompanying drawings illustrating a ma chine embodying theinvention in its preferred form and the following detailed description of the construction therein shown.

Figure '9 is a view similar to Figure 8 illustrating certain of the parts in diierent positions.

The machine embodying the invention, as illustrated in the drawings, comprises a platen frame, one of the side rails of which is indicated at 2, a substantially fiat platen, 4 mounted for vertical movement in said frame, a line space frame, a

-portion of which is indicated at'B, mounted for forward and rearward movement on said platen frame, and mechanism for imparting line spacing movement to the linefspace frame at the end of each return movement of the carriage, all as shown and described in applicants pending application referred to above.

Upon the line space frame is mounted a type 'carriage or head indicated as a whole at 20 upon which are supported the usual series of type bars each carrying one or more types for engaging the work sheets supported on the platen. The type bars are arranged to be operated by a power driven mechanism in the `present machine, and this mechanism in part is carried by the carriage. The carriage also carries the usual series of keys forming the keyboard of the machine and controlling the coaction of the type bars with the power driven mechanism. The carriage also carries a master wheel by which the totalizers or registers are driven and mechanism for driving the master wheel differentially by power to set up or enter successively the various digits of a number step by step in a register. y

The type carriage is mounted for movement forwardlyA and rearwardly with the line space frame and is also mounted for lateral movement on said frame in a right-hand direction to letter space during a typing operation and for return movement in a left-hand direction to restore the carriage to position for starting the typing of a line. The carriage is provided with front and rear wheels or rollers arranged to engage respectively the front and rear rails of the line space frame of which the rollers engaging the rear rail I0 of said frame are indicated at 24. The carriage is acted upon by the usual metallic band 26 having one end attached to the carriage and connected with the usual spring drum 28 which tends yieldingly to move the carriage constantly in a right hand direction along the rails of the line space frame. The letter spacing movement of the carriage is controlled by the usual escapement mechanism indicated as a whole at 30.

The several type bars of the machine, one of which is indicated at |12, are arranged to be actuated by power through suitable connections from a continuously rotating uted shaft 238. This shaft is continuously driven from a motor 32 through suitable driving mechanism, such as that shown in Figure 4. The driving connections for the several type bars are selectively engaged with the iiuted shaft by means of key levers 246.

The mechanism for actuating the accumulating devices of the column registers comprises a series of vertically movable toothed differential actuator racks, one of which is indicated at 324, a toothed or fluted shaft 350 continuously driven from the motor 32 for moving the racks upwardly when engaged with the shaft, a differentially operated shaft 320 actuated by the racks during their downward movement through the engagement of the racks respectively with gears 346 fixed to the shaft, and a master wheel 304 for actuating the accumulating devices 300 of a column register 289 connected with the shaft through suitable gearing indicated at 314.- The actuator racks 324 are selectively engaged with the fluted shaft 350 upon the actuation of the respective type bar levers of the numeral type bars under certain conditions and are moved upwardly by said shaft to the positions required for their subsequent action. The racks are then disengaged from the fluted shaft and are moved downwardly by a spring pressed bail 332. During their downward movement, the racks are engaged with the respective gears 346 to operate differentially the shaft 320.

The machine shown in said pending application is provided with a space bar mechanism for controlling the escapement and both the type bar mechanism and space bar mechanism operate to cause step-by-step movements of the carriage by letter space intervals., The said machine is also provided with a column tabulator mechanism and with a decimal tabulator mechanism for releasing the escapement to space the carriage greater distances.

All of the mechanisms of the machine briefly described or referred to above have substantially the same construction, arrangement and mode of operation of parts as the corresponding mechanisms illustrated and described in applicantspending application Serial No. 281,772 and need not further be described herein.

Crossfooter register mechanisms As shown clearly in Figure 2i of the drawings, the shaft 320 is extended beyond the side plates 239 of the type carriage at each end of said carriage and right and left hand cross-computing registers or crossfooters 546 and 548 are mounted at the respective ends of the carriage. The totalizer mechanisms of these crossfooters are connected respectively with the ends of said shaft for operation by the shaft. The totalizer mechanisms of the crossfooters preferably are substantially identical and each of these mechanisms has the same general construction arrangement and mode of operation of parts as the corresponding mechanism illustrated and described in the patent to Foothorap, No. 2,145,254, dated January 3l, 1939.

The mechanism for driving the totalizer of each crossfooter comprises a master wheel 550 mounted on a shaft 552 to rotate therewith but shiftable longitudinally of the shaft to select the denomination of the totalizer mechanism corresponding with the denomination in which the master wheel 304 is located with relation to the column register. The master wheel 550 is driven by mechanism similar to that shown and described in Foothorap Patent No. 1,847,429, dated March 1, 1932, and in Foothorap Patent No. 2,032,691, dated March 3, 1936. The master wheel shaft 552 is journaled in bearings in the side plates 553 of the crossfooter frame and is driven from the actuator shaft 320 through a gear 554 xed to said shaft and meshing with a gear 556 journaled on and shiftable axially of the shaft 558 fixed to one of the side plates 553. When the machine is set for addition, the gear 556 is arranged to mesh with a gear 560 secured to the master wheel shaft 552. To set the crossfooter mechanism for subtraction, the gear 556 is shifted axially out of engagement with the gear 560 and into engagement with one section of a twin gear 562. The gear 562 is journaled on a shaft 564 secured to the adjacent side plate 553 and the other section of said gear is constantly in mesh with the gear 560, the gear 562 rotating idly when the machine is set for addition.

The value indicating wheels 566 are journaled on a shaft 568 mounted in the supporting plates 569 of the crossfooter frame and are arranged to be driven in opposite directions respectively, for addition and subtraction by toothed denominational number wheels 510 with which the master wheel 550 is arranged to mesh. The wheels 510 are journaled side by side on the shaft 512 supported in the crossfooter frame plates 569 and said wheels are connected with the value indicating wheels by intermediate gears 514 and 516. The master wheels of the two crossfooter registers are respectively shifted axially step by step to the right, looking at the front of the machine, into engagement successively with the wheels 510 to select the denominations corresponding to the denominations of the column register wheels successively engaged by the master wheel 304 by mechanism described later in this application.

Each crossfooter register is provided with a two-way transfer mechanism of the type illustrated and described in Patents No. 2,032,691 and No. 2,145,254, referred to above. This mechanism includes a series of transfer heads 516, one for each denomination, mounted to rock upon a fixed shaft 580 to either side of a central normal position. Rocking movement of a transfer head is effected initially by the engagement of a wide tooth on the corresponding denominational number wheel 510 with a trip member 582 on the head arranged in the plane of said tooth to rock the head in one direction or the other at the time in the movement of said wheel at which a transfer is required. Movement of the head is continued in the direction in which it is initially vrocked by actuating mechanism including a bell crank actuator lever 584 pivoted at 586 on the frame of the crossfooter, a spring 588 connected with the downwardly extending arm of the lever and urging the forwardly extending arm of the lever toward the axis of the head and a link connection 598 between the head and the latter arm of the actuator lever. head and its actuating mechanism is such that, in the normal position of the parts, they assume a dead center position providing a toggle lock resisting the action of the spring 588, in which position they are yieldingly held by a pivoted detent 592 urged by a spring 594 against a roller 596 mounted on one end of the link 598. Combined carrying ngers and locking dogs 598 tensione-d by springs 688 are mounted on each head and are each provided with a projection 602 arranged in the plane of the next higher denominational number wheel 518 to impart the carrying step of movement to said wheel upon the rocking of the head.

Transfer resetting mechanism for crossfootei` registers After each ofthe transfer heads 518 is rocked into inclined position in the ymanner above described, to execute a carry, the head remains in this position until it is positively restored to the normal or upright position shown in Figure 5. The present machine is provided with mechanism which operates, immediately after the master wheel 384 leaves the units of cents position in a column register, to restore automatically the transfer mechanism of the crossfooter or crossfooters which may be then in operation. This mechanism comprises a rod or shaft 684. carried by spaced arms 686 secured to a rock shaft 688 mounted to turn in bearings in the crossfooter frame. In restoring the transfer mechanism, the rock shaft 688 is turned in a counter-clockwise direction (Figure 5) thereby swinging the rod 684 downwardly into engagement with the projecting ends 584a of the forwardly extending arms of any of the actuator levers 584 which may have been swung upwardly out of normal position by the rocking of a transfer head, thereby swinging said arms of said levers downwardly therewith. This restores the links 598 and the transfer heads to their normal positions shown in Figure 5.

rlhe mechanism for thus actuating the rock shaft 688 comprises an arm 618 secured to the rock shaft, a lever SI2 xed to a rock shaft 6I4 mounted in bearings 5&5 on the frame of the carriage and links ISIS connecting the arm GII) with the lever SI2. The rock shaft 688 is turned in the opposite direction by mechanism comprising an arm SI5a secured to `said rock shaft, a lever 6l1 pivoted at 6I9 on the frame of the crossfooter mechanism and connected with the arm 6I5e by a link 62I. The lever SI1 is acted upon by a coil spring 623 which constantly tends to swing the same in a counter-clockwise direction (Figure 5) and thereby to turn the rock shaft 688 in a clockwise direction.

'I'he lever 6I2 is connected by a pitman 6I8 with a crank pin 628 fixed in a disk 622 journaled on a screw stud 624 threaded into a supporting bar or block 626 secured to one of the side plates of the frame of the carriage, the pitman having a lost motion connection with the lever SI2 by means of a stud 628 secured in the lever and engaging in a slot 638 in the pitman. The disk 622 constitutes one element of a one The arrangement of each v' revolution clutch for actuating the pitman 6I8 and the arm IiI2.y Pivoted at 638 on the disk is a ypawl 632 arranged `to engage the teeth of a ratchet wheel 634 journaled on the hub of the disk 622 (see Figure 7). The pawl is acted upon bya leaf spring 638 which tends to swing the pawl into engagement with the teeth of the ratchet wheel 634. A gear wheel 648 is fixed to the hub of the ratchet wheel 634 and is continuously driven by means of a gear wheel 642 secured on an extension on the shaft 238 projecting beyond the adjacent side plate 'of the carriage. n

The pawl 632 is held out of engagement with the ratchet wheel 634 during the movement of the master wheel 384 past the denominational number wheels 388L of a column register until the master wheel passes from the number wheel yof the units of cents position by means of a detent lever 644 pivoted at 646 on a bracket 648 .attached to the frame of the carriage, which lever carries a detent rstud 658 arranged to engage the tail of the pawl as shown in Figure 5. The lever 644 is acted upon by a coil spring 652 which lnormally holds the lever yieldingly in position with the stud 658 in engagement with the pawl, the movement of the lever under the action of the spring being limited by means of a stop `pin 654. When the master wheel 384 passes from the units of cents position in a register, the lever 644 is swung in a lclockwise direction (Figure 9), thereby disengaging the stud 650 from the tail of the pawl 632 to allow the same to be engaged with ratchet wheel 834 by the spring 638. Upon the engagement of the pawl with the ratchet wheel 634, the disk 622 is given a single rotation by said Wheel and, during this movement of the disk, the lever 6l2 is swung downwardly by the pitman 6 I 8 thereby actuating the rock shaft 688 and the rod 684 to restore the rtransfer mechanism. Immediately afterthe lever 644 is actuated to cause the stud 658 to release the pawl 632, said lever is, itself, released by its actuating mechanism and, when the tail oi the pawl has passed the stud, the lever is swung back to normal position by the spring 652 thereby rlocating the stud in the path of the tail of the pawl. As continued rotation of the disk 622 engages the tail of the pawl with the stud 658, the pawl is again disengaged from the teeth of the ratchet wheel 634, and the disk 622 comes to rest. The usual spring actuated reverse rotation preventing pawl 654a is kpivoted in the crossfooter frame and arranged to engage a notch in the disk 622 to prevent reverse rotation of the disk when the pawl 632 is held out of engagement with the ratchet wheel 634.

The present machine is provided with mechanism for moving the master wheel 558 of each of the crossfooter mechanisms from denomination to denomination along the series of numeral wheels 518 during the passage of the master wheel 384 of the icolumn register actuating mechanism through the several denominations of a column register having the same general construction, arrangement and mode of operation of parts as the corresponding mechanism illustrated and described in Patent No. 2,145,254, and in part in Patent No. 2,032,691, referred to above. Each master wheel 558 is shifted by a master wheel carriage 655 movable on a guide 651 in the directionv of the axis of the wheel and connected by a link 658 to a forwardly extending crank arm 66| fixed to the upper end Lof a vertical rock shaft 663 mounted to turn in bearings in the crossfooter framework. A rea-rwardly extending arm 665 is xed to the lower end of said shaft and is connected by a link 654b with one of a pair of longitudinally slidable coupling bars 656 and 656e, one for actuating each of the master wheel carriages. These bars are mounted side by side between a pair of laterally spaced housing plates 658 secured to the frame of the type carriage and said bars slide between upper and lower series of rolls 660. The rock shafts 663 are each acted upon by a coil spring 652 connected, in one crossfooter, with the arm 66| and, in the other crossiooter, with the arm 665 which tends to swing the shaft in a direction to maintain the corresponding carriage 655 in starting position with the master wheel 55D in a position just above the rst numeral wheel 516. These springs, acting through the connecting mechanism, urge the coupling bars 656 and 656e to the left (Figures 8 and 9). A coupling dog 666 is pivoted at 668 upon each of the coupling bars and is acted upon by a coil spring 618 which tends to swing the same upwardly into position to engage and interlock with a lug 672 on the base of each column register. A pin or stud 614 is mounted on each of the coupling dogs 666 and engages in an elongated slot 616 formed in the adjacent housing plate 658, the stud cooperating with cams formed at the opposite ends of the slot to swing the dogs downwardly out of engaging position with relation to the lug 672 on the column register.

Normally the dogs 666 lie in their upper or operative positions, one behind the other as illustrated in Figures 5 and S, with the pins 614 located in the le t hand portions of the corresponding slot-s 676 and adjacent to the respective cams at the ends of the slots (see Figure 8). When the carriage has advanced the printing point to a position within one letter spa-ce of a column position on work sheet on which a number is to be printed or a position at which the master wheel 384 of the column register actuating mechanism is within one space of the rst number wheel 399* on a column register, the coupling dog or dogs which are in operative position will engage the lug cl2 on the column register and will hold the corresponding slide or slides stationary during the continued advance of the carriage. Because of the relative movement of the carriage Upon which the crossfooter mechanisms are mounted and the slides 855 and Ga, the corresponding master wheel or wheels 556 will be advanced from denomination to denomination across the corresponding series of numeral wheels 518. When the master wheel 384 advances one step beyond the lowest denominational order of a. column register, the pin on each coupling dog, which is engaged with the lug 6l'2, is engaged by the cam at the right hand end of the corresponding cam slot 816 and the dog is depressed out of engagement with the lug thereby releasing the corresponding coupling slide. Each rock shaft 663 is then swung by the corresponding spring 662 in a direction to carry the master wheel 556 back to its normal or starting position and the corresponding coupling slide is moved back to the left to its starting position shown in Figure 8 with relation to the carriage. Figure 9 shows the coupling slides and associated parts in the positions which they assume when the coupling dogs have disengaged the lug 612 on the column register and the slides have been moved part way back to their starting positions.

The clutch control detent lever 644 is swung in of the slides, comprises a connecting lever 618 pivoted at 888 on the detent lever 644 and connected by the spring 652 with the bracket 648, this spring normally holding the connectingr lever in the position shown in Figures 8 and 9 with relation to the detent lever with a projection 682 on the connecting lever in engagement with a stop pin 684 nire-:l to the detent lever. Thus, with the levers in the relative positions shown in these figures, the spring 652 tends to swing the detent lever 666 in a counter-clockwise direction. To enable the connecting lever 616 to be actuated from the coupling slides, the lever is provided with two downwardly extending projections 686 and 665e, the projection 686LL being arranged in front of and extending below the projection 686 shown clearly in Figures 5, 8 and 9. The projection 686'UL is arranged to be engaged by a connecting pin 638 secured in the slide 656 and extending forwardly therefrom through a slot in the forward housing plate 658. The projection is arranged to be engaged by a connecting pin 668 xed in a bar 690 rigidly secured to the slide 553e, said pin also extending forwardly from the slide through a slot in the forward housing plate The length of the pin 688a is such that it does not project forwardly far enough to engage the projection 686e as shown in Figure 5. In order to enable the projections 686 and 686a to ley-pass the pins 688 and 688a when the coupling slides are held stationary during the advance of the carriage, each of the projections is provided with a cam face 69| arranged to engage the corresponding pin.

The above described mechanism has the following rnode of operation: Referring to the mechanism controlled by the coupling slide 656, when the slide is in its normal left hand position, with relation to the housing plates 658 as shown in Figure 8, the connecting pin 688 is located in the position shown in this figure with relation to the projection 686a on the connecting lever 6?3. When the slide is held stationary by the engagement of the coupling dog 666 with the lug 812 on a column register, the cam 69| on the projection 666e is engaged with the connecting pin 563 by movement of the lever 618 with the carriage and the laterally extending arm of the ccnneoting lever G13 is lifted t0 allow the pin to pass the projection after which the connecting lever is swung baci: to its normal position by the spring 652, these movements of the lever being produced without eiecting the detent lever 644 which remains in its normal clutch disengaging position. When the coupling slide 656 is released by the action of the coupling dog, and the slide is moved back to the leit with relation to the carriage by the slide actuating springs (Figures 8 and 9), the connecting pin 688 engages the right hand side of the projection 686a thereby swinging the detent lever 644 into the position shown in Figure 9 to set in operation the one revolution clutch. Dtu'ing this movement of the detent lever 644 vthe connecting lever 618 swings as a unit theremovement of the coupling slide. After the 'pin 688 passes beyond the connecting lever 618, the levers 644 and 618 are restored to their normal positions as shownv in Figure 8 by the actionoi the spring 652 so that the stud 650 on the lever 644 will again engage the tail of the pawl 632 to release the clutch as the disk 622 rcompletes a revolution.

The one revolution clutch is tripped in the same manner by the action of the coupling slide 656e, the pin 688 on this slide acting on the connectingilever 618 to swing the detent lever 644 to trip the clutch during the retracting movement of the slide.

The one revolution clutch shown in Figure is arranged to reset the transfer mechanisms of both the crossfooters in the event that the several transfer mechanisms have been operated during the passage ofthe carriage through the zone of a column register. To this end the rock shaft BIA is extended across the rear of the type carriage and one f the arms or levers SI2 is attached to each end of the shaft. Mechanism connected with each of these levers having substantially the same construction as that shown in Figure 5 is provided for restoring the transfer mechanism of each crossfooter. In the present application it has been considered necessary to show this mechanism only as applied to the right hand crossfooter It is to be understood that, except as defined in the claims, the invention is not limited-to the particular construction and arrangement of parts of the illustrated embodiment of the invention but that the invention may be embodied in other forms within the scope of the claims.
