This invention relates to a new and useful improvement in printing mechanisms de--,

various transactions and operations performed by the machine may be recorded on different sheets or strips of paper. For instance, in th making up of statements for country banks, or customers, whether daily or monthly, .it is the practice to distribute various items constituting said statements in different columns where they may be checked over by the bank and lts customers.

The statement is usually sent to the customer. It is desirable that, at the time of preparing these statements to be issued to the customers, the bank retain a record thereof for its own use in order that at the end of the day or whatever-period is covered by the issued statements, the bankwill have a complete record of the issued statements for purposes of re-checking and correcting errors in the issued statements should any be found to exist.

To illustrate a customers statement:

This statement is made up in the usual way on the regular slips issued by the bank at the time the customers book' is balanced and shows two or morecolumns, the dates and amounts checked out on the said dates, the old balance, or balance forwarded, the amount of deposits, the total of checks re-- turned, the balance on the day the statement was issued, and total of the old balance, plus the deposits which equal the new balance as.

determined by subtracting the checks re-- Checked New Ex- Old Deposits out. change. balance. 1, 234. 50 3, 500. 00 3, 675. 00 4. 5O 1,0.)5. 00 1,075. 00 6, 000. 00 5, 000. D0 6. 0D 2, 059. 00 2, 546. O0 100. 00 1, 900. 00 50 745. 50

In some instances, in making up bank statements, it is desirable, for checking pur poses, to record each item comprising the totals of the difi'erent columns, and these may be. obtained by the use of the adjustable blocks to be hereinafter described. lln other instances, it is desirable only to obtain the totals of'the various columns appearing in the statement to be issued, in which event such totals may be controlled by the several total Keys of the machine, the adjustable blocks on the main paper carriage being moved to one side, or entirely removed, if this latter operation is desired.

In. the drawings, I have shown a combined typewriting and adding machine such as is disclosed in French Patent No. 383,719, dated January 16, 1908, and which is also shown in application for United States Letters Patent filed by Hubert Hopkins, Serial No. 310,739, filed April 9, 1906, to which my tally roll attachment is applied; but it is obvious that the principles of operation. hereinafter described and the mechanism for carrying the same into effect may be utilized with other types of machines.

In the following description, I shall utilize, as far as practicable, the same reference numerals which are applied in said French patent to refer to corresponding parts. I will state, however, that in the present machine the multiplying mechanism and associate parts have been omitted, but

the wheels 268-, which form the productwheels in multiplying operations of the mechanism disclosed in the French patent.

have been retained. In the present machine they are only used as adding wheels; however, the multiplying mechanism may be re tained if desired Typewm'ter mechanism. I have not disclosed all the details of the typewriter mechanism in this case as it is only necessary to state that the printing type carried by the forward ends of the racks make aD'lIIIPIBSSlOII on the paper supported by the platen of the laterally movable carriage. The main paper carriage has mounted thereon and movable therewith, a

notched rack 39, on which notched rack are adjustably-mounted various steps, to beherethe escapement of'said-carriage to letterspace the same when a digit key in the adding department 1s operated, means for preventing lateral movement of the carriage when a digit key of the adding department is operated so that the adding department may record various items in column order, means for line-spacing the platen of this carriage upon the operation of the adding mechanism, etc, all of which are described in said French patent, before referred to, and therefore need not be specifically described. here. v

The totalizerc.

These consist of two sets of wheels 119 and 288 mounted in frames which are movable so as to engage and disengage the totalizer wheels with the racks whereby, when said racks make an excursion, they will not only position the printing type both front and rear, but will register the numbers printed in one or the other set of totali'zer Wheels depending upon which is selected to receive such number. The means for controlling the excursions of the racks comprising the setting-up mechanism operated by the keyboard of the adding mechanism, torms no part of the present invention, nor is it necessary to describe the carrying mech anism and'its manner or control, as these or equivalent parts are fully disclosed in said French patent.

Tally roll frame.

Referring now to Figs. 1, 2 and 8, it will inner face of which cross arm is mounted a platen 505 of rubber or other suitable material. This frame 503 forms a support for the paper guides 506 and 507 and also a mount for the paper feed'rolls 508and 509, the former of which is preferably idle. 510 is a cross bar connecting the lower legs of the frame to which is secured a plate 511 operating in the groove of shaft 502, said plate having some play in said groove so as to provide lost motion, the purpose of which will hereinafter be described. 512 indi- 'cates a frame having upward extensions bent to embrace the shaft 502, said extensions being located within and adjacent the legs of the frame 503 so that the frame 512 will be moved in all positions of the frame 503. Frame 512 has side members 513 preferably bent, outwardly therefrom. the upper ends of which side members provide a support for a guide roller 514' for the paper, and the lower ends of which side members provide a mount for the spool 515 which carries the roll of paper 516 from which the tally strip entirely across said rear wall, as shown.

The frame 503 carries an escapement rack 521 below the shaft 502, on which rack is a depending portion carrying a roller which bears on the outer face of track plate 520 (see Figs. 2 and 3). By means of this roller 522, the upper end of frame 503 is permitted to move forwardly so that its platen 506 can make a printing impression, such forward movement of frame 503 not disturbing the frame 512; and likewise, the lower end of frame 512 is permitted to move outwardly slightly if for any cause the ten sion on the tally strip is such as to require such movement. This outward movement of the lower end of frame 512 is also desirable in introducing a new roll of tally I paper.

which carries it in the full line position.

shown in Fig. The spring 525 connected An inward extension on each side to the rod 523 at all times holds'the roller against the escapement bar and tends to move the Same inwardly so the said bar and frame will occupy their normal positions.

TaZZg roll frame escapement.

Reference has been made heretofore to the printing of different numbers on the sheet of paper carried by the main paper carriage in column order and horizontal alinement, which numbers, as the typewriter carriage is advanced leftwardly, through the medium of the adjustable blocks 40, causes certain of said numbers, in at least three of the columns, (or such number of separate accumulators asmay be arranged upon the shaft 48) to be separately accumulated.

Assuming now that it is desirable to make a record On the tally strip of the different items constituting the three columns registered and accumulated in the groups of forward totalizer Wheels 119 (or the totals thereof), it follows that, as the typewriter carriage advances leftwaydly, and, through the blocks 10 carried thereby, operates the escapement so asto successively bring the groups of totalizer wheels 119 under control of the racks 100,,the tally-roll carriage, whose starting or home position. like the typewriter carriage, is at the right of the machine, looking from the front, will have to he stepped leftwardly so as to present dif ferentprinting surfaces of the tally-roll to the recording mechanism so that the tallyroll will have corresponding columns of figures or totals thereof impressed thereon. The frame 503, before referred to, has a spring 526 (see Fig. 23) connected thereto, (the right hand end looking from the front of the machine), the other end of the spring being connected to-one of the brackets 501 so that the energy of said spring is at all times exerted to draw the frame 503 leftof the frame, with which recesses and projections cotiperates an escapement pawl 527 (see Fig. 23) in the form of a bell crank lever, said escapement pawl being pivoted to a bracket 530'extending inwardlyfrom the track rail 520. Thistrack rail is cut away or recessed to permit the operation of the escapement pawl. The escapement pawl has a leaf spring member 52?? secured thereto and Whose free rear end coiipera-tes with the projections 521 on the escapement rail, the purpose of this spring 527 being to absorb the shock of the tally roll carriage. I do not in this application claim the construction and arrangement of this escapement mechanism and do not deem it necessary to further describe the same in detail, as it is fully illustrated and described in the parent case filed May 20, 1916, Serial No. 98,853.

531 represents a bar slotted at each end to engage screws which find a bearing in some suitable frame members of the machine, (see Fig. 2) whereby, through the medium of these guiding slots, the bar 531 may be 7 to the pivoted members 42 of the blocks 40,

except that the rear ends of these. pivoted members 535 lie in a different horizontal plane (see Fig. 20). In this manner, the different stop blocks on the notched bar 39 may cofiperate with their respective tappets .without interference with other tappets.

The front end of tappet 533 is beveled or inclined as shown in Fig. 2'so that as the typewriter carriage moves leftwardly, in the direction of the arrow, on hair 39, the mem bers 535 will engage the inclined end of the tappet 533 and cam the same rearwardly- Upon the return movement of the. types writer carriage to the right, thetappet 533 swings on its pivot in a manner well known without vibrating the bar 531.

Returning the tally-roll carriage.

In United States Letters Patent No. 1,120,862, granted December 15, 1914: upon an application for improvements in carriage return mechanism filed by me, I have shown a a construction for returning the typewriter carriage from a constantly rotating motor shaft, this carriage return mechanism being carries a gear wheel 542 which is designedto mesh with rack teeth 543 formed on the inner face of the escapement bar 521. The carriage return mechanism, including the gear wheel 542, is mounted in the frame of the machine, while the escapement bar, having the rack teeth which mesh therewith, is carried by the tally-roll frame which is slidingly mounted on the casing of the machine. This casing is removable and when the parts are assembled, if the teeth on gear 542 do A tappet 533 is mounted upon eas es not mesh Xactly with the rack teeth 543, then the sliaft 539 may yield slightly until, by a relative movement between the teeth, they are brought into proper mesh with each other; likewise, the escapement bar 521 and the lower end of frame 503 may yield outwardly slightly for the same purpcse.

The notched bar 39, before described, is provided with an adjustable block 553 having a cam faceprojection 554, (see Figs. 2 and 19) which, in the movement of the typewriter carriage, is designed at the proper moment to operate the bar 551, releasing the plate 544:, and permit upward movement thereof to effect an engagement between the clutch members of the carriage return mech anism. This carriage return mechanism for the tally-roll carriage is separate and distinct from the carriage return mechanism for the typewriter carriage, though it derives motion for its constantly driven shaft 535 from the same source of power, to wit, the motor drive for the calculating machine; the constantly driven shaft 535 (see Figs 2 and 3) has a miter gear 557 at. its lower 4 end which meshes witha companion gear 556 on shaft. 557 whose forward end is driven by the gears 558 which are in turn driven from the motor.

Tally roll i leeord'ing mechanism.

Referring now to Fig. 1, it will be observed that each the rack bars has a toothed extension 100 secured to the rear end thereof, for engagement with the seg ment 560, there being a segment and its connected type carrying.part 561 for each rack. 562 are type carried by the type carrying part, said type being riveted or otherwise fixedly secured in position. These type carrying parts have characters, zero, 1, 2, 3. 4-, etc., up to 9, .in the usual order.

The shaft 271, (see Figs. 1 and 13) on which the side frames 270 are pivoted, which side frames carry the shaft 269 on which the rear totalizer wheels 268 are mounted, is bent up at its middle portion, between its hearings, to permit the segmental racks 560 to pass thereunder. The hub of each segmental rack and type carrying part (560- 561) is provided with a shoulder 563 with vwhich copcrates a shoulder on a pivoted type guard carrying member 564. Springs 565 tend to hold the shoulders of these guard carrying mcmbers'in position. against their respective shoulders 563.

566 are thin flexible type guards whose forward ends normally lie over the zero type, 'in the printing line, and preventsaid zero type from making a printing impression on the tally strip; However, when-- ever any printing segment 561 is operated by movement of its controlling rack 100, it will tilt the guard carrying member 55% forwardly and uncover the type positioned liliin the printing line.

guard carrying member 564 forwardly by to the right thereof so as to uncover the Zero printing type in the printing line. It willbe seen by reference to Fig. 12, that each of the guard carrying members 564, except the one in the units column or order of lowest denomination, has a lateral projection 567 extending behind the next adjacent guard carrying member 564 identified with the column of next lowest order. Thus, when any guard, carrying member of any order is op erated, it will operat all of the other guard carrying members to the right, as seen from the front of the machine, or of lower order,

to expose the zero type in the printing line. To illustrate, if $12.50 was set up on the keyboard and the racks 100 moved forwardly to introduce this number intothe selected accumulator. the type-carrying parts of the tally roll printer would be correspondingly positioned to record this number, with the exception of the one identified with the rack of lowest order which would remain unmoved, but whose zero printing type .Would be exposed in the printing line so that zero at the right would be printed. All of is made by rocking frame 503 so as to force I the type-carrying parts of the tally roll printer of higher denomination to the left of the highest digit in the number being recorded, will remain unmoved and consequently the guards 566 will cover the'zero type to th left of the number being recorded and thesezeros will not be printed.

The printing impression. on the telly strip its platen against the exposed type in the printing line. The tally strip is in front of the platen, as shown in Fig. 1, and the ink ribbon travels over the type in the printing line and under the free ends of the type guards. The method of efiecting a printing impression, that is, forcing the tally strip 1 against the type by means of the platen car ried by. the rocking frame 503, is as follows: The shaft 502, before described, has a groove on its upper side in which is received the lower end of a plate 511, there being slight lost motion of the plate in the groove so as to permit a slightfreedom of play necessary in sliding the frame .503 along the shaft. This play or lost motion is also taken advantage of to effect the operation of the (alley strip feed rolls, as will presently appear. I v

t one end of the shaft 502 is fixed an arm 568, which arm has a stop block 569 on its outer end (see Fig. 5) for engagement with.

in manufacture. .,The rock arm 5-68 extends The tiltin of' this 1 the i through an opening in the rear Wall of the casing, (see Fig. 5), and is provided having a cam slot formed therein for engagement with a stud or pin carriedby the cam 266 "of the machine which is mounted on shaft 81, which latter is the main operating shaft of .the machine and is rocked at every operation of the -machine. 'Thus', whenever the machine is operated, the initial movement of the pin on cam 266, passing through the concentric portion of the slot in cam 571, will maintain the bar 570 practically stationary to enable the digit type 562 to be moved to their printing position, after which and during, the final movement of said cam the bar 570 will be depressed to make a printing impression on the tally strip, On the initial reverse movement of cam 2 66. the bar 57 0 will be lifted, and during the final movement of the cam, held sta tionary. The upper end of bar 570 is guided between the forked-ends of a bar 572 (see Figs. 4 and 5), which is slotted to receive a screw, whereby the same is variably ful crumed on the side framing of the machine. This bar 57 2v is pivotally connected to a rock arm 573 fixed on one endof the sleeve 574 mounted on a cross shaft 57 5. The opposite end of this sleeve carries a rock arm 57 6 to which is connected the rear end of a bar 577 whose front end is slotted to receive a screw secured to a bracket on the, frame of the machine whereby the front end of bar 577. It will be observed that there is a straight face between the inclined ends .of this T-shaped head. This is to insure proper engagement of the adjustable blocks there with at the end of each tabulating movement of the tally roll-carriage. Unlike the tappets 43, 533, and 552, heretofore=described,

the bar .577 is not designed to be momentarily vibrated and then rcturnedto its'nornhal position. On the contrary, the blocks 578 are so adjusted that when the tally roll carriage is in its. home position, and at the end of each tabulating movement thereof,

the bar 577 shall be held "in its rearward position. Whenever the bar 577 is forward, the printing mechanism for the tally strip is disabled and thus by the adjustment of blocks 578, this disablement'can be effected in any position that the typewriter carriage may occupy, that is, stationary position wherein other parts of the machine may be operated. v

The upper end of bar 570 is held within the forked end of the. lever 572 by means of springs 580, (see Figs, 4: and 5 springs also tend to move the bar 5'77 forwardly.

When-the bar 577 is moved rearwardly, the pin 569 is moved into the slot 568 and thus bar 570 is connected to the rock arm 568 and ateach operatiomof the machine the shaft 502 will be rocked.

In order to prevent thepin 569 from slipping out of its slot, 1 provide a guard member 581 which is loosely mounted on shaft 502 and which has a finger 581 at its forward end normally located in front vguard member, 581 is depressed. when the rock arm 568 is depressed, this: post will traverse the slot and eventually, contact with the bottom wall thereof, whereof and below the plane of the pin 569. Thus, when the parts are in normal position, the finger uncovers the slot. A. spring 582 tends to hold the guard member 581. upwardly at all times. carried. by the rock arm 568, which post passes through a curved slot in the guard mally in theposition shown in Fig; 5 in which the post 583.is located in the upper end of the curvedslot thereof while the However,

upon the guard member will be depressed with the rocking arm and the operation of the ribbon feeding mechanism effected. The. depression of rock arm 568 will cause the,

finger 581 toplosev the end of slot 568 and prevent any displacement of thepin 569% In the rocking of the arm 568, the walls of the slot will, inv the lowermost position of.

said rocking;- movement be inclineddownwardly and the pin would have a tendency to ride'down this incline and out of the slot were it. not prevented from doi presence of a guard finger 581?.

When the rock arm 568 is depressed to rock the shaft 502, the platen carried by the frame 503, isbrought into contact with the type in the printing line, but the pressure necessary for ciiecting the printing impression is not exerted upon said platen until the lost motion between the plate 511 and slot in the shaft 502 is taken up. When this lost motion has beenovercome, the final pressure is placed upon the platen, this occurring at the last operation of the down ward movement of the rock arm 568.

These 583 indicates a post.

ng soby the When the rock arm 568 is lifted, it is immaterial whether the frame 503 is first rcstored to its normal position or whether the lost motion of theplate in the groove is first taken up. In any event, the normally retracted position of the frame is determined by the roller 522 carried by the escapement bar (see Figs. 2 and 8). When the roller 522 contacts with the track plate 5:20 and arrest'sthe frame 503 in its retracted position, the shaft 502 continues to be rocked, thereby absorbing the lost motion referred to until the stop member 569 engages the track plate 520. This continued rocking movement of the shaft 502 is utilized in linespacing the tally strip.

I Zinc-spacing the tally Sni Oneend of the paper feed roll 509 (the righthand end,.as viewed from the front of tliema-chine, see Fig. 3), is provided with a hand-wheel 586 for manual operation. The

,oppositeend of said feed roll is provided with a ratchet wheel 587, (see also Fig. 9). This ratchet wheel cooperates with a springpressed centering pin 588 carried by an arm pivotally connected to the frame 503, which centering in permits the manual rotation of the feed roller 509 in either direction.

To mechanically effect the line-spacing of the paper, I mount a plate 589 (Fig. 9) on .the shaft 502, said plate having a slot and pin connection with the frame 503, so as to permit independent movement thereof, and

said plate also having a projectionwhich fits into the groove, of shaft 502,- but not tightly, permitting a slight independent play of said plate. Plate 589 carries apaperfeeding pawl 590 which is normally held in. operative position by a spring 591. A bar 592 F igs. 2 and 3) is mounted in a bearing provided by one of the brackets 501, said bar eing tidjustably held in position by means of ass-t screw 593. Thisbar is" cut away at intervals, as at 592 so that whenever said hair is adjusted to locate one of its cutaway portions opposite, or in line with, the paper--feeding pawl, 590, (see Fig. 9) said paper-feedingpawl is permitted to engage the ratchet wheel. and line-space the tally strip. When, however, the paper-feeding pawl 590 rides upon the bar, as shown by dotted lines in Fig. 9, the vibration of the pawl 590 will beidle. Thus, after a printing impression, and after the frame 503 has been retracted the full measure of its retractive movement, the continued rocking of the shaft .502. in taking up tost motion therebetween and said frame, will rock the plate 589 and vibrate the paper-feeding pawl 590. If the bar 592 is so adjusted as to have a recess'in line with said paper-feeding pawl, then the paper-feeding pawl will engage, and by operating the ratchet wheel,

line-space the tally strip; but, if said paperfeeding pawl is riding the bar, its vibration will be idle.

The bar 592 is sufficiently long (see Fig. to hold the paper-feeding pawl 590 in a disabled position throughout the entire travel of the tally roll carriage, except when it occupies that position which may be desig- .the blocks should be adjusted accordingly,

such as the carriage return block, eta, so as to roperly articulate and harmonize the various devices which are controlled by the typewriter carriage.

Feeding the tally roll i n/le ribbon.

The pin 585 which is vibrated when the arm 568 is rocked, as before described, will, in its descent, strike a lever 593 pivoted at 59t to one of the frame bars of the machine and through extension 593 thereof rock a plate 595 through the means of a connecting link 596 (seel ig. 8). Plate 595 I 1ng connection is to take care of any cockcarries a spring-pressed pawl 59'? which c0- operates with a ratchet 598 on a shaft 599 (see Fig. 8). Thus, whenever the frame 568 is rocked to effect a printing impression, the shaft 599 will be rotated a short distance to efi'ect a feeding of the ink ribbon.

Ribbon reverse mcbam'sm.

600 indicates the ink ribbon which, as shown in Fig 15, is designed to be wound upon spools 601. Each of these spools has a miter gear 602 connected thereto with which miter gears 603 are designed to alter-,

nately engage, depending uiponthe direction of feed of the ribbon-'the ribbon being taken up or wound upon the spool which is being driven. The shaft 599, before referred to,

is of such length that when one of these gears 603 is in drivingengage nent with one spool, the other of said gears 1s out fdr1ving engagement, and vice versa.

formed in part by a fixed curved Wall 60%, to which the ends of the ribbon may be secured, and a. movable wall 605, the latter being pivoted at one end. and connected to a spring 606 which tends to open said well, as shown at the l ft in Fig. 15. The free end of this swinging wall carries a pin 607,.which extends down through a curved slot in the bottom spool head. In the osition of the parts shown in Fig. 15, the pm 607 has been per- Each bf' the ribbon spools 601 has a hollow cote mitted to move outwardly, into the path of a hook on the end of a sliding bar 608. Up to this time, the spool at the right-hand end, in Fig. 15, has been positively driven and exhaustion from the spool at the left-hand side of said figure has permitted the outward swinging of the removable Wall and the location of the pin in front of the hook, The

continued'rotation of the lefthand spool in the direction of the arrow, by the drawing off of the ribbon, will cause the pin-607 to slide the bar 608 leftwardly moving the pinion 603 out of driving engagement with the right-hand spool and the pinion 603, at the left, into engagement with the spool at the left. The spool at the left now becomes the driven spool and in winding up the rib bon thereon, its rotation will be reversed from that indicated by the arrow and the ribbon will in due course fold in the movable wall so as tolocate the pin-607 out of the path of thehook on the end of the bar 608. The bar 608 has a hook on its opposite end and the spool at the right side of Fig.

15 has a fixed and movable wall, above de-' scribed. The bar 608 has an upward extension carrying two collars 609 slidingly mounted on shaft 599. Between these collars and members ailixed to the shaft are.

springs 610 one of said springs being interosed between each collar and ailixed memer of the shaft. The purpose of this yielding of the teeth between gears 603 and,;602.- If the gears are cockedfthat is, not brought into proper registration when the bar 608.

is moved, one of the springs 610 will be compressed until by the next rotation of the shaft 599, the teethof the gears are brought into proper mesh.

There is a centering device for holding the 'shaft599 in its two positions, this consisting of the bar 611, having a roller on its upper end-which drops into either one of two .V-

These ribbon guides are held in their outer position by means of springs 618 and have a slot and pin connection with the arms .617,

.(see Figs. 10 and The purpose of this is toenable said guides to be pressed. inwardly by the platen at each type impression and afterward the guides move the ribbon away from the type so as nottointerfere with subsequent movement of the type. The

type are of course held stationary during the printing impression as is also the ribbon and the paper feeding mechanism, heretofore described. The ink ribbon. is ted just before each type mpression, while thelinespaclng or papenfceding mechanism, when in position for papenfeeding operation, is

operative only after a type impression.

ing to numbers introduced into the addingmechanism of the machine and which are so i eeaaee printing mechanism upon the depression of the total key to record the total on the sheet recorded on the sheet of paper carried by thetypewriter carriage. As before stated, whenever the bar??? is permitted to occupy its forward position, no printin can be There ore, it is eiiected on the tally roll. I necessary to adjust the blocks 578.130 positions wherein the bar 577 will beforced follows, therefore, that if the blocks 5Y8 are moved, the bar 577 will not be pushed rearwardly at the end of a tabulating o' eration, and obviously certain of "the b ocks may be removed to obviate'item printing in certain columns and permit item or total printing in other columns. 1' will assume, for the purposes of the present description, that it is not desired to rint items in any one of the columns on tie tally strip, but that it isdesired to record only the totals thereof as said totals are yielded from the wheels 119 and 268 and recorded on the sheet of paper carried by the typewriter carriage. To do this, it is necessary to plaiie the printing on the tally strip under control of the two tota'al keys marked T and R. T., (meaning total and rear total).

Referring now to the construction disclosed in Fig. 21, it will. be seen that when the total key is depressed, it will pull for-f wardly a bar 170, thereby rocking a lever 172. This lever is connected by a link 174 to a bell crank lever 173 having a forward extension which engages a pin on a bar 113, connected to the frame 49, so that when the total key is depressed, the wheels119 are brought into engagement with the racks 100. The bell crank 173 also has a rearward extension lying under a member 180 of a hell crank which shifts the cams 82-109 (see 21) moving them in their central" The operation oi the tooth 232 for engagement with the segn'icnt 233 Wherebythe pendants 235 may be posior neutral position. total key through the link 185 lifts the tap pct 84 out of the patlrof pin 83 and thus prevents the lifting of frame 58 which canrearwardly at the proper time to causes. record to be made on the tally St1'1P."-Il2.

of paper carried by the typewriter carriage, I also efi'ect the printing of such total on the tally strip. 1 provide the bar 577 with a shoulder 577 (see Fig. 2) in front of which lies a bell crank lever 620 (Fig. 21) pivoted to a bracket on the frame of the machine, and which bell crank lever has a slot and pin connection with a bar 621 having a pin 622 on its lower end lying under the forward extension 172 of hell crank 170. Inthis manner, whenever the total key is depressed, the bar 621' is pulled downwardly and through the bell crank 620, the bar 577 is moved to the rear so that the printing devices of the tally-roll attachment are brought into operation so as to print the totals of the columns. Of course, the printing of the totals of the columns, as controlled by the total key, just described, can be 'used in connection with the printing of the items on the tally strip, if desired.

The total key for the rearregister wheels 268 may have its extension 304 located over they pin 622 ,(see Fig. 21), so that when this key is depressed, the total, as represented in the wheels 268, will also be recorded on the'tally strip. I do not claim in this application the particular means for shifting the cams 82'-109 as the same is more fully shown and describedin the French Patent 'mesh with the racks, shifting the cams to Hubert Hopkins, No. 383,719, dated January 16, 1908.

I do not deem it necessary to refer in detail to the parts controlled by the rear total key except to say that when it is depressed, in addition to pulling down the link 185, be fore described, pulling down bar 621, in the present application, causing the wheels 268 to 82-409 to their second or neutral position, the depression of said rear total key will also lift the levers 102. r I have not herein referred to the operation of subtraction, which is necessary in making.

out statements where the difference between debits and'cr edits has to be determined, but

'tioned over the lifting bars 247. The pendants are each slidable upon the arm 236 of a vertically movable bar 239 having a stepped portion 243 to cotiperate with a stop granted upon applications filed by me.

The carriage return mechanism for the typewriter is not illustrated in detail as this may be similar in all respects to that illustrated in Patent No. 1,120,862, dated December 15, 1914, granted upon an application filed. by me.

The use of the non-print key may not he required, but if such is desired, the mechanism employed in the Hubert Hopkins Patent No. 1,080,694, dated December 9, 1913,01 any other desired form, may be employed. It is desirable, however, in the list- 7 ing of designating characters, such as dates, customers numbers, etc, to provide means for automatically preventing the accumulation. of such numbers as the totals thereof are unnecessary. The mechanism shown in my pending application, Serial 310,759,493, filed April 7, 1913, may be, employed for this purpose.

I do not in this application claim the details of the ribbon reversing mechanism, as the same forms the subject matter of United States Patent No. 1,245,637, issued to me November 6, 1917. y
