GENERAL DESCRIPTION The instant invention is shown applied to the Ellis type of accounting machine, the basic principles of operation of which are so well known in the art that it is vbelieved unnecessary to go into a detailed description thereof. Therefore patents: Nos.

1,197,276 and 1,197,278, issued September 5, 1916, to Halcolm Ellis; No. 1,203,863, issued November 7, 1916, to Halcolm Ellis; Nos. 1,939,804; 2,038,717; and 2,082,098, issued respectively December 19, 1933; April 28, 1936; and June 1, 1937, to Raymond A. Christian; and No. 2,079,355, issued May 4, 1937, to Charles L. Lee.

While the present invention is shown embodied in the well-known Ellis type of `accounting machine, it is not the intention to limit this invention to this particular machine, as it may easily be adapted for use in almost any type of accounting machine.

The present machine has a plurality of denominational rows of amount keys, which in adding operations control the positioning of corresponding actuators, said actuators in turn positioning corresponding printing sectors and actuating the wheels of the selected totalizers to add therein the amount set up on the keyboard. The present machine is equipped with three adding totalizers and a consecutive number counting device. The totalizer usually referred to, in the machines of the above-mentioned patents, `as the No. 3 totalizer is used for consecutive number counting, and its construction is modiiied to obtain this result.

The machine is provided with a traveling carriage which is arranged to be tabulated manually or automatically from col-umn to column under control of tabulating stop lugs on control blocks adjustably mounted on said traveling carriage, in cooperation with tabulating stop bars and controlling means therefor.

The different totalizers :are selected and conditioned for addition by means of camming lugs on the control blocks, in cooperation with hanging bar levers for the respective totalizers.

In the machine illustrated herein, the three adding totalizers and the consecutive number totalizer are selected and conditioned for subtotal operations by means of their respective sub-total control keys, and these tctalizers yare selected and conditioned for total operations by means of a total control key used in conjunction with their respective sub-total control keys.

The mechanism described in general above, which is pertinent to the present invention, will now be described in detail.

DETAILED DESCRIPTION Framework The mechanism of the machine embodying the instant invention is supported by main frames 40 and 4| (Figs. 1, 2, and 5), said main frames connected by cross frames 42 and 43 and by various other cross frames, rods, and shafts.

In figures such as Fig. 5, where the framework is shown in phantom by dot and dash lines, where the dot and dash lines of such framework do not show behind the other parts, it indicates that such parts are in front of the framework.

The frames 4U and 4| are secured to a machine base 44, to which is secured also a case or cabinet 45 which encloses the mechanism of the machine, and which supports a laterally shiftable traveling carriage 46 later to be described.

Operating mechanism The machine embodying the instant invention is driven by a -conventional type of continuously running motor 39 (Fig. 2) supported by a framework 41, secured to the machine base 411. The armature shaft 48 of the motor 39 carries a worm wheel 49 which meshes with, and drives, a clutch drivingmember 59 vfree on a stud 5| in the framework 41. Also free on the stud 5|, andfcontained within a boring in the driving member 56, is a clutch driven member 52 carrying a stud 53 upon which is pivoted the lower end of a link 54, the upper end of which is free on a stud 55 in a drive arm 56, secured to a main drive shaft 51 journaled in the frames 48 and 4|.

A machine starting bar 58 has stems 59 and 69, parallel portions of which extend through and are guided by slots in a plate 6| mounted on the frame 46. The stem 59 is pivotally connected to a plate 62 free on a stud 63 in the frame 45. The plate 62 carries a stud 64 embraced by a bifurcated portion of one arm of a three-armed lever 65, free on a stud 66 in the frame 40, while the stem 68 is pivotally connected to an arm 61 of said lever 65. An'arm of the lever 65 carries a stud 68 which cooperates with a shoulder on an arm 69 free on a stud 10 in the frame 48, and having pivotally connected thereto one end of a pitman 1|, the other end of which is bifurcated to straddle a stud 12 in the frame 48. The pitman 1| carries a stud 13 embraced by a slot in an upward extension of a lever 14 free on a stud 15 in the motor framework 41.

Depressing the starting bar 58 rocks the plate 62 and the lever 65 counter-clockwise and clockwise, respectively (Fig. 2), to move the stud 68 out of. engagement with the shoulder on the arm 69. This frees the arm y69, pitman 1|, and lever 14 to Athe, action of a torsion spring 16, which immediately rocks `said lever 14 counter-clock- Wise to move a bent-over ear 11 thereof out of the path of the upper end of a clutch engaging lever 18, free on a stud 19 in the clutch driven member 52. The lever 18 has adjustably connected thereto a plate 88 carrying a stud 8|, to which is anchored one end of a clutch band, the other end of said band being secured to the clutch driven member 52. v Y

Moving the ear 11 out of the path of the upper end of the lever 1.8 frees said lever to the action of a spring 83, which immediately rocks said lever 18 counter-clockwise to expand the clutch band 82 to cause said band to grip the inner surface of the continuously rotating clutch driving member 50, whereupon said driving member immediately rotates said driven memberr counter-clockwise in unison therewith. One rotation of the clutch driven member 52 (Fig. 2), by means of the link 54, oscillates the arm and the main drive shaft 51, first counter-clockwise and back to normal position through an approximate angle of 60 degrees.

During return movement of the link 54 and the arm 56, a flat surface 84 on a stud carried by said link engages an upward extension 85 of the lever 14 and rocks said lever and the arm 69 clockwise to move the ear 11 into the path of the lever 18 and to move the shoulder on said arm 69 beyond the stud 68. spring 86 to rock the plate 62 clockwise and the lever 65 counter-clockwise, to return the stud 68 into the path of said shoulder, to retain the ear 11 in the path `of the upper end of the lever 18 when the stud 84 passes beyond the extension 85. Continued rotation of the clutch driven member 52 causes the upper end ofthe lever 18 to engage the ear 11 to contract the clutch band 82 todisengage the clutch driven member from the clutch driving member to terminate machine operation.

The lever 18 is assisted in disengaging the clutch band 82 by a cam lever 81 free on a 'stud 8,8 in the motor framework 41. The lever 81 is urged clockwise by a compressible spring 89' to maintain a camming surface thereon in the path of a roller 96 mounted on an arm 91 secured to the clutch driven member 52. Near the end of rotation of the clutch driven member 52, the roller 96 engages the camming surface 95 to rock the lever 81 counter-clockwise to compress the spring 89, whereupon the declining portion of said camming surface, in cooperation with said roller, urges the clutch driven member 52 clockwise to assist the lever 18 in contracting the clutch band 82 and retaining said band con* tracted.

Counterclockwise engaging movement of the arm 69 and the lever Y14 is limited by a downward projection 98 of the pitman 1| contacting the stud 1|). One rotation of the clutch driven member 52 and one complete oscillation of the arm 56 and main shaft 51 drive the machine mechanism through one cycle of movement, which is the requisite for adding, total, and subtotal operations.

The usual non-repeat mechanism is provided for preventing repeat cycling of the machine when the starting bar 58 is inadvertently retained depressed at the end of a machine operation.

VDepressing the starting bar 58 (Fig. V2) also renders mechanism. elective which causes' the traveling carriage 46 to ber automatically tabulated from one columnar position to the next.

In addition to the regular starting bar 58, the machine also has aV vertical feed starting bar 99 and an auxiliary starting bar |06. Depressing the bar 99 releases the ,machine for operation, causes the traveling carriage platen roll to be automatically rotated to line-space the record material supported thereby, and prevents automatic tabulation of the traveling carriage. Depressing the auxiliary starting bar |88 initiates what is termed an idle operation `of the machine, in which the automatic rotation or line-spacing of the platen and the automatic tabulation of the traveling carriage are rendered inoperative.

Amount keys Inasmuch as the different rows of amount keys and the mechanism associated therewith are substantially duplicated in each denominational order, it is believed that a description of the one row of amount keys shown in Fig. l, and the mechanism associated therewith, will be sufi-lcient for the purpose of this specification.

This permits a v The row of amount keys shown in Fig. 1, are assembled in a keyboard framework comprising a top plate I 02, a partition plate |03 for each row of keys, and right and left side plates (not shown), said side plates being secured to the frames 40 and 4|. The upper ends of the keys 16| protrude through, and are guided by, corresponding openings in the top plate |02, while the lower ends of said keys are guided by square studs |05 therein, in cooperation with vertical slots |06 in the partition plate |03 for this particular bank. Each of the keys |0| has encircling the stem thereof a spring |04 compressed between a washer |01, integral with said key stems, and the bottom of an opening |08 in the plate |03. The springs |04 urge the keys |0| upwardly to compress felt washers |09 between the washers |01 and the top surfaces of the openings |08, said top surfaces being formed out of bent-over portions of said openings |08 and having slots therein which admit the stems of the keys |0|. rIhe felt washers |09 deaden the sound when the amount keys are released by preventing a meta-lto-metal contact between the washers |01 and the tcp of the openings |08.

Each row of amount keys has a detent plate ||2 (Fig. 5) hinged on a rod, not shown, supported by the keyboard framework, said plates being spring-urged counter-clockwise.

Depressing one of the keys |0| causes a bentover lip l i0 on the lower end of the stem thereof to by-pass an angular lower edge of the detent plate H2, whereupon said detent latches the key in depressed position. If another key is depressed in the same row, the bent-over lip H0 of said key rocks the plate ||2 clockwise sufficiently to release the key previously depressed, thereby constituting what is termed "fiexible key action.

Mechanism not described herein, but fully disclosed in said parent application, is provided for automatically rocking the detent plates ||2 clockwise near the end of adding operations, to release the depressed amount keys.

Depressing any one of the keys |0| (Fig. l), except the 9 key, moves the square stud |05 therein into the path of a corresponding one of a series of graduated steps |32 on an actuator rack |33, for this particular amount bank, a notched portion of the forward end of which fits in a corresponding slot in a rod |34, supported by the frames 40 and 4|, and the rearward end of which is bifurcated to fit a corresponding slotted portion of a bar |35 also supported by the frames 40 and 4|. It is, therefore, evident that the actuator |33 is mounted for horizontal reciprocating movement, which is imparted thereto in a manner presently to be described.

Depressing any one of the amount keys |0| also moves a zero latch (not shown), which retains the actuator |33 in zero position when no amount key is depressed, to ineffective position. There is no corresponding step |32 on the actuator |33 for the stud |05 in the 9 key, and depression of this key merely releases the zero latch and the rack travels full distance rearwardly until a wall |33, formed by the notched forward end thereof, contacts the rod |34.

tensioned between the segment |39 and a leading har |48 extending between two similar arms |49, only one here` shown, secured on the shaft |46,

normally maintains a projecting portion of the segment |39 in yieldable contact with the leading bar |49.

When the arm 55 (Fig. 2) is oscillated in the manner explained earlier herein, a roller |50 carried thereby, in cooperation with an irregular camming slot |5| in a cam plate |52, secured on the right-hand end of the shaft |46, rocks said shaft, the arms |49 (Fig. 1), and the leading bar |48 first rearwardly or counterclockwise and then back to normal position through an invariable excursien during each machine operation. Initial movement rearwardly, or counterclockwise, of the leading bar |48, by means of the spring |41 (Fig. 1), causes the segment |39, the reducer arm |45, and the actuator |33 to travel in unison therewith until such movement of said actuator is terminated by one of the steps |32 thereon contacting the stud |05 in the depressed amount key 10|. This positions the actuator and the reducer arm |45 commensurate with the depressed amount key, and the leading bar |48 completes its rearward movement independently or the segment |39, flexing the spring |41.

Initial movement counter-clockwise of the reducer arm |45, by means of a link |52 (Fig. 1) connected between an arm |53 of said reducer arm and a printing sector |54 for this particular amount bank, positions said printing sector in proportion to the depressed amount key. The printing sector |54 is pivotally mounted on an arm |55 free on a printer shaft |56 journaled in the printer framework and the frame 40.

Directing attenticn to Fig. 1, after the leading bar |43 has completed its initial movement rearwardly to cause the actuator |33, arm |45, and printing sector |54 to be positioned, a roller |10 (Fig, 2) mounted on the same axle as the roller |59, said axle being supported by the arm 56, in cooperation with a camming groove |19 in an arm |30 flexibly connected to an aliner shaft |9| jcurnaled in the frames 40 and 4|, rocks said shaft clockwise, near the end oi' the initial movement counter-clockwise of the arm 56. Secured on the shaft 48| (Fig. 1), and moving in unison therewith, are two arms |82, only one here shown, supporting a cross bar |83 having secured thereto an alining bar |84, which, upon clockwise movement of said shaft |8I, engages the proper one of a series of teeth cut in the periphery af the segment |39 to aline said segment, the printing sector |54, and the actuator |33 while printing is being effected and while the totalizers are being engaged with said actuator ,in adding operations.

After printing has been effected, return movement clockwise of the arm 56 (Fig. 2) causes the roller |18, in cooperation with the cam groove |19, to rock the shaft 8| counter-clockwise to normal position to disengage the aliner |84 (Fig.

1) from the segment |39. Continued return movement clockwise of the arm 56 causes the roller |58, in cooperation with the cam slot |I, to return the shaft |46 and the leading b-ar |48 clockwise. During its return movement the leading bar |48 picks up the reducer arm |45 and returns said arm, the printing sector |54, and the actuator |33 forwardly to normal or zero position, as shown in Fig. 1, where the zero latch again becomes effective to retain said actuator and connected parts in zero position.

T otalz'zers rIhe machine embodying the present invention has four totalizers, numbered 1 to 4, respectively (Fig. 1), assembled in Vertical pairs at the rear of the machine. The #l and #2 totalizers are mounted in a framework |86, secured Vto the main frames 40 and 4|, and two plates |81, only ene here shown, connect the framework |81 to a framework |88, which supports the #3 and #4 totalizers. Each of the fourtotalizers has a single set of wheels, adapted to be actuated by their corresponding actuators |33.

In the invention illustrated herein, the #3 totalizer is never engaged with the actuators during adding operations, Vthis totalizer being used as a consecutive numbering device, and is advanced step by step in a manner later to be described.

Wheels |89 and 35 of the #l and #2 totalizers, corresponding to the denomination illustrated in Fig. l, are arranged to cooperate respectively with rack teeth on the upper and lower surfaces of the bifurcated portion of the actuator |33. Wheels |36 and |31 of the #3 and #4 totalizers are adapted to cooperate respectively with'teeth on the upper and lower surfaces of the bifurcated portion of an extension |98 connected to the actuator |33I and supported by a slotted bar ist mounted in the framework |88.

The #1, #2, and #4 totalizers are adding totalizers, and, taking the #l totalizer as an exampleafter the leading bar |48 (Fig. 1) has completed its initial movement rearwardly andthe actuator |33 has been positioned by the depressed amount'key ll mechanism, controlled by the traveling carriage and presently to be de-A scribed, causes the wheel |89 to be engaged with the actuator |33, and return movement forwardly of said actuator, under the influence of the leading bar |48, rotates said wheel |89 in a clockwise direction to add therein the value of the` amount set up on the depressed amountI key |i||.

In total and sub-total operations the wheel |38 of the #-1 totalizer is rocked into engagement with the actuator |33 prior to the initial movement rearwardly of said actuator, which movement reversely rotates said wheel to Zero position, which position is determined by one of the diametri-cally opposed teeth on the tripping cam 253 coming into contact with the pawl 28| This positions the Wheel |83, the actuator |33, and the printing sector |54 in accordance with the yamount standing on said wheel, after which functioning of the printing mechanismV causes this amount to be recorded on the record material.

In total operations the wheel |83 is rocked out of engagement with the actuator |33 prior to its return movement forwardly, and consequently said wheel remains in a zeroized condition. In sub-total operations the wheel |83 remains in engagement with the actuator |33 during its return spear/ee movement forwardly, and consequently is returned to its original position.

The totalizer engaging mechanism will be explained more` in detail later in connection with the traveling carriage mechanism.

Traveling carriage The travelingcarriage 46 (Fig. 1) is supported for horizontal shifting movement on the case 45 by means of corresponding ways 232 and 203 *mounted respectively near the rear of the traveling carriage and the case, said ways having therebetween ball bearings284, which reduce friction and insure accurate alinement or` the platen |11 with the printing mechanism. The front of the traveling carriage is shiftably supported by vmeans or rollers 235, carried thereby, in cooperation with a rail 233, mounted on the case 45. A series of rollers 281 on the carriage, in cooperation with a recessed or horizontally grooved portion of the rail 235, prevents the front ofthe traveling carriage from tilting upwardly, and a series of brackets 233 secured to the frame of the traveling carriage, in cooperation with a flanged portion of the way 283, prevents the rear of the traveling carriage from tilting upwardly.

Accounting machine tabnlating mechanism eling carriage to various columnar positions.

Initiating machine operation by depressing the ,;starting bar 58 (Fig. 2) causes the accounting machine tabulating mechanism to function automatically, or said tabulating mechanism may be operated manually by depressing a tabulating key 215, located on the right-hand side of the accounting machine keyboard between the vertical feed and auxiliary starting bars 33` and |38. .A manipulative lever 21S (Fig. 2), one end of which protrudes through a slot in the keyboard plate 3i, is provided for rendering the automatic tabulating mechanism effective or ineffective at will. Y

Adding operations The Nos. l, 2, and 4 totalizers are selected for addition. by means of add hanging bar levers in cooperation with corresponding tappet lugs on a series of control blocks located inthe various columnar positions of the traveling carriage on the stop .bar 214 (Fig. 5). Inasmuch as similar mechanism is used to select the three totalizers for addition, it is believed that a description of the mechanism used in connection with the'No. 1 totalizer will Ybe sufficient.

A control block 305 (Fig. 5) has a tappet lug 325 adapted to cooperate with the upturned end 326 of a No.1 add hanging bar lever 321, free on a stud 328 in the frame 42. A link 329 (Fig. 6) connects the hanging bar lever 321 to an addcontrol pawl 33|! free on a stud 33| in the frame 4|, andthe rearward end of said pawl is normally in the path of a shoulder 332 on an add control plate 333, free on a studV 334 in the frame 4|,and urged counter-clockwise by a spring 335. The plate 333 has a stud 333 embraced by the bifurcated upper end of a link 331, the lower end lof which is pivotally connected to a lever 338 loose on a stud 339 in the frame 4|. The lever 333 Vhas secured to the lower end thereof a shoeV 345, the sole of which cooperates with an arcu- 341 secured on'the main shaft 51.V

A stud 348 in the plate 341 rotatably supports a totalizer engaging lever 349, having in the upper'end thereof a stud 350, which pivotally supports one end of a link 35|, the other end of which is pivotally connected to an arm 352 secured on a No. 1 totalizer engaging shaft 353 journaled in the totalizer framework |86 (Fig. l). Also secured on the engaging shaft 353 are two similar cams 354, only one here shown, having similar camming slots 355, which cooperate with rollers 356 mounted on opposite ends of a rockable frame 351, which supports the No. l totalizer. Pivotally mounted on the stud 35!) (Fig. 6) is a totalizer engaging pawl 358 urged counterclockwise by a spring 359 to normally maintain a projection thereof in contact with a stud 366 in the lever 349.

An extension 35| of the pawl 358, in cooperation with a square stud 362 in the plate 341, is

adapted to rock the No. 1 totalizer into engagement with the actuators |33 in adding operations, and a square stud 363, in the plate 341, in cooperation with a prominence on the lever 346, is adapted to disengage the No. l totalizer from the actuators |33 near the end of adding operations.

Upon operation of the machine, initial movement clockwise of the main shaft 51 and the totalizer engaging plate 241, as viewed in Fig. 6,

moves the arcuate surface 346 out of the path of the shoe 345 to release the lever 338, link 331, and plate 333 to the action of the spring 335. However, when the traveling carriage is so positioned that the tappet 325 (Fig. 5) does not engage the upward extension 326 of the No. 1

hanging .bar lever 321, the pawl 336 remains in the path of the shoulder 332 of the plate 333, as shown in Fig. 6, to obstruct counter-clockwise movement of said plate, under iniluence of the spring 335. When the above condition prevails, initial movement clockwise of the plate 341 causes an upward extension 364 of the pawl 358 to engage the stud 336 to rock the extension 36| out of the path of the stud 362, thereby permitting the lever 349 to continue to pivot relatively to the plate 341, and consequently the No. 1 totalizer engaging mechanism does not function.

When the traveling carriage 46 is tablulated to the columnar position corresponding to the control block 385 (Fig. 5), the stop lug 354 on said block, contacting the tabulating bars controlled by the tabulating mechanism, arrests the traveling carriage in a position wherein the tappet lug 325 engages the upward extension 326 of the lever 321, thus rocking said lever clockwise, as viewed in Fig. 5. Said clockwise movement of the lever 321 raises the link 329 (Fig. 6) to rock the pawl 330 counter-clockwise out of the path of the shoulder 332. In this instance, when the arcuate surface 346 moves out of the path of the shoe 345, upon initial movement clockwise of the plate 341, the spring 335 rocks the plate 333, link 331, and lever 338 counterclockwise to move the stud 336 out of the path of the extension 364.

Therefore, after the actuators |33 have been positioned by the depressed amount keys, and near the end of the initial movement clockwise of the plate 341, the extension 36| of the pawl 353 engages the stud 362. This terminates movement of the lever 349 in relation to the plate 341 and causes said lever to move in unison with said plate, which movement, by means of the link rocks the arm 352, shaft 353, and cams 354 counter-clockwise. Counter-clockwise movement of the cams 354, by means of the slots 355 therein, in cooperation with the rollers 356, rocks the totalizer frame 351 clockwise to engage the Wheels |89 of the No. 1 totalizer with the actuators 33. The No. l totalizer remains in engagement with the actuators |33 during their return movement forwardly, to add in said totalizer the amount set up on the keyboard.

After the actuators |33 have completed their return movement, and near the end of the return movement counter-clockwise of the plate 341, the stud 363 engages the lever 349, causing said lever to move counter-clockwise in unison with said plate 341, to rock the arm 352, shaft 353, and cams 354 clockwise to normal positions, as here shown, to disengage the wheels |89 of the No. 1 totalizer from the actuators |33. Return movement counter-clockwise of the plate 341 (Fig. 6) causes the arcuate surface 346, in cooperation with the sole of the shoe 345, to rock the lever 338, link 331, and plate 333 clockwise to normal positions, as here shown, to move the shoulder 332 on said plate beyond the end of the pawl 330 so that said pawl may again move into the path of said shoulder to obstruct counterclockwise movement of the plate 333.

A train of mechanism similar to that described for engaging the No. 1 totalizer with the actuators is provided for each one of the four totalizers. For a detailed description of such totalizer engaging mechanisms, reference may be had to the Christian Patent No. 2,038,717.

The Nos. l, 2, 3, and 4 totalizers are selected and conditioned for sub-total operations by means of their respective sub-total keys 312 to 315 inclusive (Figs. 5 and 6), and a total operation may be performed in any one of the four totalizers by using a total key 316 in conjunction with the proper one of the sub-total keys 312 to 315 inclusive. It is believed that a description of a sub-total and a total operation in connection with the No. 1 totalizer will be sufficient, as the mechanism and the manner in which it functions are substantially the same for each of the totalizers.

A repeat key 31|, the sub-total keys 312 to 315 inclusive, and the total key 316 are mounted on the left side of the accounting machine keyboard. The lower ends of said keys extend through corresponding slots in the angle plate |21 and the upper ends of said keys extend through corresponding slots in the keyboard plate |26. Each of said keys has a spring, similar to the spring |28 for the release key |25, which urges said keys upwardly to normally maintain a shoulder, formed on the upper end thereof, in Contact with the lower surface of the plate |26.

Depressing the No. 1 sub-total key 312 (Fig. 6) moves a notch 311 therein opposite a bent-over ear 313 on a key latch lever 319 pivoted on a stud 380 in the frame 4|, whereupon a spring 38| urges said lever clockwise to latch said key 312 depressed. Clockwise movement of the lever 319 causes a stud 382 in the lower end thereof, in cooperation with a camming surface 383 on a lever 384 free on a stud 385 in the frame 4|, to rock said lever clockwise. Upon clockwise movement of the lever 384, an extension thereof, in cooperation with a stud 386 in a lever 381, also free on the stud 385, rocks said lever 381 clockwise in unison therewith. A spring 383 yieldingly connects the lever 381 to a totalizer engaging pawl 389, also free on the stud 385 and mounted adjacent said lever 381, said spring 388 normally maintaining said pawl in contact with a stud 390 in the lever 391. Also pivotally mounted on the lever 391 is a tctalizer disengaging pawl A39|, urged counter-clockwise by a spring 392 into engagement with a stop on said lever 381. Clockwise movement of the lever 381 moves the ends of the

pawls

389 and 39| intor the path of the lower end of the engaging lever 349, said lower end being reinforced by a block 393.

Upon operation of the machine, initial movement clockwise of the plate 341 (Fig. 6) causes the end of the lever 349 to engage the pawl 389 to rock the wheels |89 of the No. 1 totalizer into engagement with the actuators |33 in the manner explained hereinbefore. Initial movement rear- Wardlyof the actuators |33 reversely rotates the wheels |89 to zero, to position said actuators and the printing sectors to the amount standing on said totalizer wheels. When the plate 341 nears the end of its initial movement, and after printing has been effected, mechanism presently to be described rocks the latch 319 counter-clock- Cri wise to disengage the ear 318 thereof from the notch 311 to release the No. 1 sub-total key 312,r This counter-clockwise restoring movement of the latch 319 permits the levers 384 and 381 to be 1 returned, by gravity, counter-clockwise to normal positions tomove the

pawls

389 and 39| out of the path of the lower end 393 of the lever 349, so that the pawl 39| will not engage the lever 349 and disengage the wheels |89 from the actuators 33. As the wheels |99 remain in engagement with the actuators |33 during their return movement forwardly, said wheels are returned to their original positions to reenter the amount in the No. l totalizer, after which the stud 363, near the end of return movement of the plate 341, engages the lever 349 to disengage the wheels |89 from the actuators.

Depressing the total key 316 in conjunction with the No. 1 sub-total key 312 selects and conditions the No. 1 totalizer for a total operation, which is exactly like a sub-total operation, with the exception that the latch 319 is not rocked counter-clockwise to release the sub-total key 312 near the end of the initial movement of the plate 341. Consequently the pawl 39| remains in the path of the projection 393 and said projection by-passes said pawls during initial movement clockwise of the plate 341. Return movement counter-clockwise of the plate 341 causes the end of the lever 399 to engage the pawl 39| to rock the totalizer wheels |89 out of Vengagement with the actuators |33 prior to return movement forwardly of said actuators |33, thereby leaving the wheels |89 of the No. 1 totalizer in a zeroized condition. Near the end of machine operation the latch 319 is rocked counterclockwise, in a manner presently to be described, to release the No. 1 sub-total key 312.

Release of control keys `Inasmuch as the time of release of the subtotal keys 312 to 315 inclusive determines whether the operation is a sub-total or a total operation, it is impossible to use the regular amount key releasing means for releasing these keys,

and therefore a separate releasing mechanismY slot in the forward end thereof, in cooperation 75 with a stud 49| in* a foot-shaped lever 402 pivoted on a stud 403 in the frame 4|, and by means of a slot 404 in tnev rearward end thereof, in cooperation with a studV 403 in the upper end or a lever 496 fulcrumed on a stud 401m theY frame 4|. Mountedadjacent. the .bar 400, and somewhat similar in outline thereto, is an auxiliary release bai` 408 (Figs. 6 and 8), the forward end of which is slotted to straddle an eX- tension of the'stud 40|, and the rearward end of which is pivoted on an extension of the stud 405.

In sub-total operations the total key 431.6 is not depressed, which causes theenlarged portion of a wedge 409, pivotally mounted on the stem of saidv key, to be positioned between studs 4|8 and 4|| carried respectively by Ythe bars 409 and 498, to connect said bars so that they will shift forwardly in unison when the No. 1 sub-total key is depressed. Forward shifting movement of the bar 408v rocks the lever 406 clockwise to move a foot-shaped portion` 4|2 vthereof into position to be engaged by an extension 4|3 of the stud 348 in the plate 341. Initial movement clockwise of the plate 341 engages the No. 1 totalizer wheels with the actuators |33, as explained above. Near the end of initial movement clockwise of the plate 341, and after printing has been effected, the extensio-n 4I3 engages the foot 412 to rock the lever 466 counter-clockwise to shift the bars 408 and 499 rearwardly to rock the latch 319 counterclockwise to disengage the ear 318 thereof from the notch 311 to permit the key 312 to be-springreturned upwardly to undepressed position.

Return movement counter-clockwise of the latch 319 (Fig. 6) permits the lever 394 and the pawls 399 and 39| to rock counter-clockwise about their pivot 385 to move said pawl 39| out of the path ofthe lever 349. This permits lthe wheels |89 of the No. 1 totalizer to remain in engagement with the actuators |33 during their return movement forwardy, to return said wheels to their original positions, to reenter therein the amount of the sub-total. At the beginning of return movement counter-clockwise of the plate 341, the extension 4|3 is withdrawn from the foot 4|2 and the spring 38| returns the latch 319 and connected parts clockwise until the ear 318 comes to rest on the edge ofthe stem of the key 312, as shown in Fig. 6. Near the end of return movement counter-clockwise of the plate 341, the stud 363 engages the lever 349 and disengages the No. 1 totalizer wheels |89 from the actuators |33. j

If it is desired to perform a total operation in the No. l totalizer, the total key 316 is depressed in conjunction with the No. 1 sub-total key 312. Depressing the total key 316 (Fig. 6) moves a notch 4|4 therein opposite a bent-over ear 4|5 of a latch 416, pivoted on a stud 4|1 in the frame 4|, whereupon a spring 4|8 urges said latch 4|6 clockwise to engage the ear 4|5 with the notch to retain the total key depressed. Depressing `the total key 316 carries the wedge 409 (see also Fig. '1) downwardly in unison therewith to move the enlarged portion thereof from between the studs 4|0 and 4||, to disconnect the bar 400 from the bar 408. An upwardly extending nger of the wedge 409, in cooperation with the studs 4|0 and 41|, retains said wedge in proper relationship with saidstuds.

It is, therefore, evident that when theextension 4|3 of the stud 348 (Fig. 6) strikes the `lever 406and shifts the bar 408 rearwardly, during the initial movement of the plate 341, no movement will be imparted to the bar 408; consequently the latch 319 will remain in its clockwise position to retain the No. 1 sub-total key 312 depressed and to retain the

pawls

389 and 39| in the path of the lever 349.

Initial movement clockwise of the plate 341 (Fig. 6) causes a stud 4|8 carried thereby to by-pass the lower end of a lever 4|9, pivotally mounted on the bar 408, said lever being yieldingly retained in a neutral position by a spring 420. At the beginning of the return movement counter-clockwise of the plate 341, the lower end 393 of the lever 349 engages the pawl 39| to rock the No. 1 totalizer Wheels |89 out of engagement with the actuators |33, before said actuators start their return movement forwardly, thereby leaving said Wheels in a zeroized condition. Continued counter-clockwise movement of the plate 341 causes the stud 4l8 to engage the lower end of the lever` 4|9 to rock said lever clockwise until a surface 42|, on the upper end thereof, contacts a stud 422 in the frame 4|, whereupon continued clockwise movement of said lever shifts the bar 480 rearwardly. Rearward movement of the bar 480 causes the projection 368 thereon to rock the latch 319 counter-clockwise to disengage the ear 318 from the notch 311 in the key 312 to permit said key to be spring-returned upwardly to undepressed position and to permit the

pawls

389 and 39| to be returned counter-clockwise out of the path of the lever 343 to normal position, as shown in Fig. 6. When the stud 4|8 moves beyond the lower end of the lever 4|9, the spring 38| returns the latch 319 clockwise until the ear 318 comes to rest on the edge of the key 312.

The total key 316 (Fig. 6) is released just after the No. 1 sub-total key 312 in the following manner.

Initial movement clockwise of the main shaft 51,Y the plate 341, and a disc |22, causes a stud |2| in said disc to by-pass the angular nose of a spring-pulled tappet 423, free on a stud 424 in the frame 4|. Return movement counter-clockwise of the disc |22 causes the stud |2| to rock the tappet 423 clockwise, whereupon a stud 425, carried by said tappet, in cooperation with an angular surface 426 on an arm 421 integral with the latch 4|6, rocks said latch counter-clockwise to disengage the ear 4|5 from the notch 4|4 to permit the total key 316 to be spring-returned upwardly to undepressed position, as here shown. After the stud |2i moves beyond the tappet 423, the spring 418 returns the latch 4|6 and the arm 421 clockwise until the ear 415 comes to rest on the edge of said key 316.

It should be remembered that in both total and sub-total operations, the pawl 389 (Fig. 6), in cooperation with the lower end of the lever 349, engages the wheels |89 of the No. 1 totalizer with the actuators |33 prior to the initial movement rearwardly of said actuators. Likewise it should be remembered that the sub-total keys 313, 314, and 315 have mechanism similar to, and functioning in substantially the same manner as, the sub-total key 312 to control their respective totalizers Nos. 2, 3, and 4.

Consecutive number mechanism As previously explained, the No. 3 totalizer (Figs. l and 3) is reserved for the accumulation of a consecutive number which is printed on the various detachable portions of the record slips. In the present arrangement, mechanism, func- Aif) tioning when the No. 4 totalizer is selected for an adding operation, causes the units wheel of the consecutive number accumulator to be advanced one digit. In the system disclosed in the parent; application, the No. 4 totalizer is selected for addition only once during a series of operations required to complete a record slip. It is therefore evident that the consecutive number accumulator will be advanced only one digit during each series of operations. Other operations performed in the No. 4 totalizer-for example, sub-total and total operations--have no effect upon the advancing mechanism for the consecutive number accumulator.

The No. 3 totalizer shaft (Fig. 4), which supports the consecutive number Wheels |96, is mounted in a rockable frame 632, similar to and functioning in exactly the same manner as the frame 351 (Fig. 6) for the No. 1 totalizer, explained earlier herein. The frame 632 is pivoted on trunnions supported by the frame |88 (Fig. 3) and the extreme right and left arms of said frame 632 each support a roller 633 (only one here shown) which engage their respective cam slots 634 in two engaging cams 635 secured on an engaging shaft 636 journaled in the framework |88. A flying lever mechanism and its totalizer engaging pawl, similar to that illustrated in Fig. 6 for the No. 1 totalizer and explained earlier herein, controls the engaging shaft 636 for the consecutive number accumulator to engage and disengage the wheels |96 (Figs. 1 and 4) with and from the extensions |98 of the actuators |36 in total or sub-total timing.

The consecutive number accumulator is not provided with an add hanging bar lever and associated mechanism for selecting and conditioning said accumulator for adding operations, but instead is provided with a step-by-step advancing mechanism now to be described.

A trip pawl 631 (Fig. 4), for the units consecutive number wheels |96, is pivoted on a rod 638 supported by the framework 632, and said trip pawl is urged counter-clockwise by a spring 636 to normally engage a rod 645 supported by the frame 662. A bent-over ear 646 of the pawl 631 normally engages a shoulder 641, on a cam lever 648 pivoted on a rod 649 supported by the frame 632, to normally restrain said lever 648 against the action of a spring 658, which is tensioned to urge said lever counter-clockwise. The lever 646 has a cam slot 65| into which extends a stud 652 in a segment 653 pivoted at 654 to a plate 644 supported by the framework |88 (Fig. 3). Gear teeth in the segment 653 (Fig. 4) mesh with the teeth of the units consecutive number wheel |96 when the consecutive number accumulator is out of engagement with the actuator extension |63, as here shown.

The pawl 631 has a shoulder 655 which cooperates with a nger 856 integral with a shaft 651 journaled in the framework |88. Secured on the right-hand end of the shaft 651 (Fig. 3) is an. arm 658, said arm and said shaft urged clockwise by a spring 659 to normally maintain a shoulder on said arm in contact with a stop stud 660 in the frame |88. The arm 658 carries a stud 66| which cooperates with the upper end of a pawl 662 pvotally mounted on the upper end of a pitman 663, the lower end of which is pivoted to a crank 664 on the right-hand end of a No. 4 totalizer engaging shaft 665 journaled in the framework |88. A spring 666 urges the pawl 662 clockwise into engagement with a stud 681 in the pitman 663.

The engaging mechanism for the No. 4 totalizer, comprising the shaft 655 and engaging cams 551 mounted thereon, having camming slots 66B which cooperate with their respective rollers 669, is similar in every respect to the No. l totalizer engaging mechanism illustrated in Fig. 6 and described earlier herein.

A link l() connects the pitman 653 to the cam arm |80 for the actuator segment aliner |84, which, it will be recalled, is rocked clockwise by the roller |18 (Fig. 2) on the arm 55 near the end of the initial movement counter-clockwise of said arm and after the actuators and ktheir associated segments have completed their wise to move the upper end of the' pawl 652,

which is normally out of the path of the stud SSL beneath said'stud. After the pawl to2 has been rocked beneath the stud Sti, the shaft 6555 is rocked counter-clockwise to engage the wheels of the No. 4 totalizer with the'actuators in add time, which movement causes the crank EGA to shift the pitman 653 upwardly, whereupon the pawl 652 engages the stud 68| and rocks the arm i558 and the shaft counter-clockwise, contrary to the action of the spring G59. Counter-clockwise movement of the shaft 551 (Figs.

3 and 4) and the ringerV 65S causes said finger,

in cooperation with the shoulder 655, to rock the pawl 631 clockwise, against the action of the spring 639, to disengage the ear 546 from the shoulder Sill of the lever-648. This releases the lever E48 to the action of the spring 55E), which immediately rocks said lever counter-clockwise, causing the cam slot tl, in cooperation with the stud 652, to rock the segment 653 counter-clockwise, to rotate the units wheel |95 one tooth space in a clockwise direction, to add one digit in the consecutive number accumulator. Counter-clockwise movement of the lever 6138 is terminated by a projection 61| thereon contacting` the shaft 551. When any one of the lower order wheels itt passes through zero, one of two diametrically opposed projections on a tripping cam 683, integral therewith, trips a pawl similar to the pawl 63?, and said pawl releases a cam lever, similar to the lever 648, which, by means of a sector similar to 653, immediat-ely advances the next higher order wheel |96 one digit.

A restoring bar Si?. (Fig. 4) is provided for restoring the tripped levers 548, sectors S53, and pawls 631 to normal positions. The bar 12 is actuated by the tota-lizer engaging mechanism and functions only after the wheels |96 have been disengaged from their sectors 553 and engaged with the actuator extensions |98. Inasmuch as the consecutive number accumulator is advanced by the finger 655 and is not engaged with the extensions |98 for advancing thereby, the bar B12 receives no movement at this time and therefore the levers 64B, sectors 653, and pawls '631 remain in tripped positions until a sub-total or total operation is performed in the No. 3 accumulator, at which time the bar 612V is actuated.

The restoring bar 672 has integral therewith two similar arms 613, only one here shown, fulcrumed on trunnions in the frame |88, said trunnions in axial alinement with the rod 649. At the beginning of sub-total or total operations, in the consecutive number accumulator, the wheels |96 (Fig. 4) are rocked out of engagementfwith the sectors S53 and into engagement with the actuator extensions |93. Immediately thereafter the `restoring bar B12 is rocked clockwise, and, in cooperation with theprojections 614 of the levers 48, restores said levers and the sectors 553 to normal positions, whereupon the springs 639 restore the pawls 637 counterclockwise to untripped positions to cause the ears B46 to move into the path of the shoulders 641 in preparation for the next advancing movement of the consecutive number device.v

In the system described in the parent application, a series of operations are necessary to complete one record slip. In the first of said series of operations the consecutive number accumulator is advanced one digit, as explained above. Thereafter the consecutive number accumulator is sub-totalized several times to print the consecutive number upon the various portions of the record slip. In the first of these sub-total operations the tripped levers V|348, sectors '$53, and pawls 631 are restoredby the bar 612 to untripped positions, as explained above.

When the No. 4 totalizer is selected and conditioned for sub-total or total'operations (Figs. 3 and 4), the engagingV shaft 665 and the crank E64 are rocked counter-clockwise, at the beginning of machine operation, prior toinitial movement clockwise of the arm |80.; Consequently the upper end of the pawl 52 movesY above the bottom of the stud ESI and `upon initial movement of the arm and the pitman S33, said pawl 662 engages said stud 66| and is rocked thereby relatively to said pitman 6&53, contrary to the action of the spring 4656 and obviously without impart-ing any movement tc the arm 658 and the shaft 65?. when total and sub-total operations are performed in the No. 4 totalizer, the trip pawl 63T (Fig. 4) will not be released, and the-units wheel |96 of the consecutive number accumulator will not be advanced.

After the restoring bar 512l has restored the lever `648, sector 653, and pawl B31, said bar is latched in an intermediate position a slight vdis-- tance away from the extension 6M and near the end of the operation the latch is disengaged and said bar 612 is spring-returned counter-clockwise to normal position, as here shown. The above action of the restoring bar 612 is necessary for transferring amounts from lower to higher denominations, during adding operations in the regular totalizers, but is unnecessaryin the No. 3 totalizer, Where the No. 3 totalizer hasbeen modified for the accumulation of a consecutive number and is not actuated by the actuators |33 (Fig. l).

Summarizing briey the foregoing'description of the consecutive number mechanism, it will Vbe seen that the No. 3 totalizer is utilized only as a consective number accumulator, and that this accumulator is advanced one step each time the No. 4 totalizer performs an adding operation, but is not advanced when other than adding operations are performed in said No. 4 totaliz-er.

While the form of mechanism herein shown and described is admirably adapted to fulfil the objects primarily stated, itis to be understood that it is not intended to confine the invention to the one form or embodiment herein disclosed, for it is susceptible of embodiment in various forms all coming within the scope of the claims which follow.
