GENERAL DESCRIPTION The machine to which the present invention is shown applied isprovided with three lines of totalizers, which, as illustrated in saidparent case, are designated the front,
or batch, totalizer line; the rear, or transaction, totalizer line; and the upper, or list, .totalizer line. The batch and transaction totalizer lines comprise interspersed totalizers, each set of which is carried on a shiftable shaft, so thata desired set of totalizer wheels are alined with differential actuators for receiving entries and for having totals read therefrom. The shafts are shifted by drum cams under control of transaction keys and a transaction differential. In order to provide for accurate alinement of the totalizer wheels with the actuators, a novel alining mechanism is provided, which is adjustable within close tolerances to obtain the best possible alinement therebetween.
Front, 0r batch, totalizer line As disclosed in said parent case, the batch totalizer line comprises two interspersed totalizers consisting of totalizer elements 350 (Fig. 5). The totalizer elements 350 are rotatably mounted on a totalizer shaft 351. The shaft 351 is shiftably mounted in bearings carried by a pair of engaging arms 352, located adjacent frame plates 194 and 199 (see Fig. 2). The engaging arms 352 are mounted on a shaft 353 so as to rock thereon. Each arm 352 is provided with a cam slot 354 (Figs. 3 and 2,695,944 Patented Dec. 14, 1954 4). Engaging each cam slot 354 is a roller 355 carried by an arm 356 mounted on a stud 357, one carried by each side frame 194 and 199. Each arm 356 is also provided with a stud 358 projecting into an open slot in each arm 359 secured on the rock shaft 353. The rock shaft 353 is actuated during the machine operation in either adding or total-taking timing in a manner described in the parent case.
The shaft 351, together with the totalizer elements 350, is shifted endwise to properly aline one or the other of the two interspersed totalizers with differentially movable actuator racks 304 (Figs. 3, 4, and 5), controlled for movement by amount keys in the usual manner. The manner in which the totalizer elements 350 are shifted 11% respect to the actuator rack 304 is described hereina ter.
Front, 0r batch, totalizer aliner When the totalizer wheels 350 are in their disengaged positions, as shown in Fig. 3, an aliner 360, engaging between the teeth of the wheels 350, maintains the totalizer wheels against rotation. The aliner 360 is long enough to span the entire totalizer line and extends from the frame 194 to the frame 199. This aliner is in the form of a yoke, having a bail and two arms 366, each of the latter having a stud 362 projecting into a cam slot 361 of the arm 359. Upon rocking of the shaft 353, the cam slots 361, engaging studs 362 on aliner arms 366, disengage the aliner 360 from the totalizer elements 350, after the totalizer elements are properly engaged with the actuator racks 304, as shown in Fig. 4.
Rear, or transaction, totalizer line The rear totalizer line includes eight sets of interspersed totalizer elements 370 (Figs. 2 and 5). A ninth totalizer is shown 111 Fig. 2 to illustrate the maximum number of totalizers which can be provided. However, the ninth totalizer is shown in the position corresponding to the add print key, which key, in the present disclosure, prevents the rear totalizer from becoming engaged with its actuators in the manner disclosed in said parent case. Therefore, as disclosed therein, nothing will ever be entered into the ninth totalizer. Therefore, for the purpose of this description, it is assumed that only eight totalizers on the rear totalizer line are actually used, which is adequate for the application illustrated.
The engaging mechanism for the rear totalizer line is identical with that described for the front totalizer line. The totalizer elements 370 are mounted on a shaft 371 shiftably mounted in bearings in a pair of arms 372, rotatably mounted on a rock shaft 373. The arms 372 are provided with notches similar to the notch 354 (Figs. 3 and 4), with which rollers 375 (Fig. 2) of arms 376, similar to the arm 356 (Fig. 4), engage. The arms 376 are provided with rollers 378 (Fig. 2), similar to the rollers 358, which project into open slots in rocking arms 379 pinned to the shaft 373. When the shaft 373 is rocked in the manner described in the parent case, the cam arms 379, through rollers 378, rock arms 376, which, through rollers 375, rock the arm 372 to engage the totalizer wheels 370 with the actuator racks 305.
An aliner 380, similar to the aliner 360, is provided for the rear totalizer line and is operated by the arms 379 in like manner.
During the operation of the machine, the totalizer shaft 371 is shifted laterally in bearings of arms 372, under control of the transaction keys, to aline the proper set of totalizer wheels 370 with the actuators 305. Thereafter, the shaft 373 is given a rocking movement to engage the selected set of totalizer elements 370 with the actuators 305 in the proper timing, so that either adding or total-taking operations may be performed in the selected totalizer.
Totalizer aliner adjusting means Each totalizer shaft 351 and 371 has provided thereon a novel means for adjusting the totalizer elements in respect to the actuators 304 and 305, so that accurate alinement can be obtained. This novel construction is the same for both totalizer shafts, and therefore the mechanism is illustrated in connection with the rear totalizer parent case. as the secondtransaction'bank. The keys 110 to 118 inclusive control the time and the manner of operation -of the totalizer engaging and disengaging mechanism, together with controlling certain functions of the printing line only. Thismechanism is best disclosed in Figs. 2,3,and4.
The left-hand end of the shaft 371 (Fig. 2) is provided with threads to receive an adjustable aliner member381 The aliner member 381 consists of a castellated nut'having aliner'discs 382 thereon, arranged to engage alining slots 383 in an alining block 384 mounted on the left side frame 194 when'the' shaft 371 is moved to engage the totalizer wheels with the actuators. The righthand end of the shaft 371 is'threaded at 385 to receive an adjusting nut 386. A yoke 387 straddles the nut 386, and the yoke is differentially shifted sidewise by a .drurncam 388 under control of the transaction keys, in a'manner to be described hereinafter, to selectively shift thetotalizer wheels 370 in relation to the actuators 305 for selecting a totalizer. When the totalizer shaft 371, together withthe totalizer wheels 370,'isassemb1ed in the mac'hine, the shaft 371 is adjusted endwise by the turning 'nut386 to properly aline the'sele'cted set of totalizer wheels 370 with the actuator racks 305. Thereafter, a cotter pin 377 isinsertedthrough notches in one face of the nut 386'and'through an'opening'in the shaft 371. This holds the-selectedtotalizer elements370 in alinement in respect to the'shifting' drum cam'388. After the 'first adjustment has been-made bymeansof thenut 386, aliner member 381 is properlywadjusted to aline the aliner discs 38 2 withthe aliner slots 383.
fterthe aliner-member 381 properly alines the discs 382 with the slots-383 in accordance with the adjustment of the nut 386, 21 cotter pin 3901 is inserted through the notches in the aliner'member 381'and through an openingin the shaft 371.
The novel arrangement including the two nuts 381 and 386 provides "a fine adjustment for a ccuratealinement of the interspersed totalizer wheels 370 with respect to the actu'atorracks 305; The'front totalizer shaft 351 istprovided with a like adjusting feature whereby the two batch totalizers may be accurately alined with the actuators 304.
.'Transact'io n keys The transaction keys-for controlling the various funcsection of the machine in the manner described in the This=bank of keys will-be referred to herein mechanism described in the parentcase.
Coacting with the studs 579 -'of the keys 101 to 109 inclusive is a differentially settable slide'689 (Figs. 6 and 9). project to the right and left "intothe path of alternatelyarranged ears 690 formed on the'slide' 689. The rela- .tionship between the studs 579 and'the ears 690 is such The studs 579 on the transaction keys alternately that, "on operation of'the machine with a key depressed,
the slide 689 is arrested in aposition comrnensurate with thegposition of the depressed key.. The slide 689 is .slotted-atits'front and'rear ends to besupported by, and slide on, collars 691 and 692 carried by studs 693 and 694, respectively. The studs 693 and 694 are riveted on the'frarne'182.
The slide 689 isprovided'with teeth 696(Fig. 9) meshing with a segment 697 of an arm 698 having a slot 699,
"into which projects a stud 700 of a latch 701 (Figs. 7 and'8).
-702 carried by the frame 182 and by the side frame The arm 698 is rota'tably-mounted on a stud (not shown). The. latch 701 ispivotally mounted on a stud 703 carried by an arm'704 alsopivotally'supported on'the stud'702. A'beam705 is pivotally mounted on the arm 704 by a stud 706. The free end of the beam 705 is provided with a'stud 707, which projects into a slot 708 of an arm 709, also pivoted on the stud 702. The arm 709 is provided with a segment 710, meshing with teeth 711 (Fig. 6') ofa type'settingand control slide 712. The'control'slide 712 is slidably mounted on the *aforesaid collars 691 and 692 and at its upper end by "a'stud '688'mounted in the framework of the machine.
The latch 701 (Figs. 7 and 8) isnrovided with a toe 713 'normallv engaginga notch 71.5, of a differential-driver '71'6. Thediffe'rential drivel- 716 is nivotedron thestud 702 and is provided with a notch 717, into which prop jects a stud 718 on the free end of a lever 719 pivoted aroundthe stud 706 as a center.
on' a stud'720carried'by theffanie'work of the machine. The lever 719 is secured to an arm 733 (Fig. 8) by a hub 721. The arm 733 is provided with a pair of rollers 722, which coact with a'pair of cam plates 723 secured to the driving mechanism of the machine. The lever 719 (Figs. 7 and 8) is provided with a roller 724, which is movable into engagement with a' surface 725 of the beam 705 in a manner .to be describedv presently.
When the cam plates 723 are rotated, the arm 733 is rocked clockwise (Fig. 6) to rock the lever 719'clockwise. Clockwise movement of the lever 719, through the stud 718 and the notch 717, rocks the differential driver 716 also clockwise. Clockwise movement of the driver 716 carries withit the latch 701'and, through thestud 700, rocks the arm 698 (Fig. 9') clockwise. Clockwise movement of the arm 698, by the segment'697, moves the slide 689 to the right. (Fig. 6) until an car 690 thereon comes into contact'with the'stud 579 of a depressed key. This arrests the slide-.689 in a position commensurate with the depressed keyand at the'same time positions thearm 698 ('Fig. 9) in a corresponding position. Arresting of the arm 698, through its cam slot 699 acting on the stud 700, cams'th'e l'atchf701 counter-clockwise around its stud 703, thus withdrawing the toe 713 from-the'notch715'to arrest: further movement of the arm 704. Counter-clockwise movement of .the latch 701 (Fig. 8) cams an 'ear 726 thereoninto a corresponding notch 727 (Fig. 6) ofalocking plate 728 supported by the studs 693 and 720, Continued movement of the driver 716, after the latch 701 has been disengaged therefrom, moves a concentric surface 729 (Fig. 7) thereof beneath the toe/713 and positively locks the latch 701 and the arm 704 in adjusted position, with the result that the stud 706 for the beam 705 is also locked in anadjusted position corresponding to the depressed key.
During the-clockwise rocking movement 'of the lever .719, the roller '724 thereon comes into engagement with the surface 725 of the beam 705 and rocksthe beam 705 Movement of the beam 705 around the stud 706 cams the stud 707 on the lower end thereof into the slot. 708 and rocks the arm 709 and the segment 710 into a position corresponding to the position in which'the arm 704 has been, adjusted and locked by the latch 701. This adjustment of the segment 710, through the teeth 711 on the slide 712, positions the slide 712 corresponding to the adjusted position of the differential slide 689.
After the control slide 712 has been positioned by the beam 705 in the manner just described, the cams 723 return the levers 719 counter-clockwise to restorethe differential driver 716 into its home position. During this counter-clockwise movement of the driver 716, when the notch 715 again comes beneath the toe 713, the toe 713 drops behind the notch 715, and, upon continued clockwise movement, the driver 716, acting through a roller 714 thereon, engages the arm 704 and restores the arm 704 and the latch 701 to their home positions.
During this movement, the se ment 710 and the control slide 712 are held in their 'adiustedpositions by means described hereinafter, and therefore the beam 705 pivots around the stud 707. The segment .710remainsin the adjusted position until readjusted during the next succeeding cycle of operation.
A counter-balancing nlate 730 (Fig. 9) is pivotally mounted on the stud 702 ad acent the slide 698 and has a slot 731', throu h which the stud 700 on the latch 701 projects. A spring 732, stretched between the counterbalancing plate 730 and the arm 698, normally maintainsthe parts in the positions shown in Fig. 9. If, during the operation of themachine, the latch 701 has a tendency to withdraw prematurely from the notch 715 due to centrifugal force, the plate 730 prevents such move ment. When the arm 698 is positively arrested, upon an ear 690 on the slide 689 coming into contact with the stud 579 of a depressed key, the 'stud 700, operating in the cam slot 699, rocks the latch 701 counterclockwise in the manner described above. Counterclockwise movement of the latch 701 moves the stud 700 thereon in the cam slot 731 to rock the counterbalancing plate 730 clockwise against the action of the spring 732. Since it is necessary to stretch: the spring v 732 to move the stud 700 in the cam slot 699, the spring 732 and the plate 730 act to prevent premature disen gagement of the latch 701 from its driver 716.
Type wheel setting mechanism The control slide 712 (Fig. 6) for the second transaction bank controls the setting of a symbol-printing type element 755 in each of the three groups of type elements shown in the parent case.
Formed on the under side of the control slide 712 (Fig. 6) are a series of teeth 756, meshing with a pinion 757, which is connected to a segment 758 by a sleeve 759. The segment 758 meshes with a ring gear 760 carried by a disc 761 mounted on the shaft 632. The ring gear 760 has inner teeth meshing with a pinion 762 carried by a square shaft 763. Also carried by the square shaft 763 are pinions, similar to the pinion 762, adjacent each one of the three ring gears 764, one being provided for each group of type wheels. Meshing with each ring gear 764 is an intermediate pinion 765 on the shaft 524. Meshing with each intermediate pinion 765 is a ring gear 766 meshing with the respective type wheels 755. Through the connections just described, the setting of the control slide 712 adjusts the type carrier 755 into a position corresponding to the position to which the control slide 712 is adjusted by the differential mechanism under the control of the depressed keys 101 to 108 of the second transaction bank to set a symbol at the printing line to identify the key which was depressed.
Totalizer-selecting mechanism The two interspersed totalized linesnamely, the Rear totalizer line on the shift 371 (Fig. 5) and the Front totalizer line on the shaft 351-are shifted to select a totalizer under control of the keys 101 to 108 in the second transaction bank through the control slide 712.
Near the upper, or right-hand, end of the control slide 712 (Fig. 6), and formed on its under side, are a series of teeth 767 in mesh with a segment 768 rotatably supported on the shaft 302. Connected with the segment 768, by a hub 769, is a gear 770 (see also Fig. 2). The gear 770 meshes with pinions 771 secured to the drum cams 388 for the Rear and Front totalizer shifting lines. The totalizer-shifting cams 388 are rotatably mounted on shafts 389. Each drum cam 368 is provided with a cam race 772, into which projects a roller 773 of the beforementioned yoke 387.
When the control slide 712 is adjusted under control of a depressed key 101 to 109, each drum cam 388 is rotated an extent commensurate with the depressed key. Each cam race 772, acting on an associated roller 773, slides the corresponding yoke 387 endwise on a pair of shafts 774 and 775 an extent sufficient to select the proper totalizers on the interspersed totalizer lines, as
described hereinbefore, alining the proper sets of totalizer wheels 350 and 370 with the actuator racks 304 and 305, respectively.
After the control slide 712 (Fig. 6) has been properly adjusted under control of the depressed key 101 to 109, an aliner 778, mounted on a shaft 776, is rocked to engage an alining segment 777, also secured to the hub 769, to maintain the drum cam 388 in its proper adjusted position during the time the totalizers are engaged with the actuator racks 304 and 305.
To actuate the aliner 778, a pair of cams (not shown) are provided, which cams, together with their drivlng connections, including a link 784, are shown and described in the above-mentioned parent case.
While the form of mechanism shown and described herein is admirably adapted to fulfill the object primarily stated, it is to be understood that it is not intended to confine the invention to the one form or embodiment disclosed herein, for it is susceptible of embodiment in various other forms.
