To all whom it mo'yconcm:

Be it known that I, HANNIBAL C. FORD, a citizen of the United States, and resident of Syracuse, in the county of Onondaga and State of New York, have invented certain new and useful Improvements in Type- Writing Machines, of which the following is a specification.

My invention relates especially to paper feeding and paper supply devices for typewriting machines and hasfor itsma-in object to provide improved mechanism for continuousribbon-like work sheets, such as those commonly termed tally strips. I

To that above and other ends, the invention consistsin the features of construction, combinations of devices and arrangements of parts hereinafter described 'and particularly pointed outin the claims.

I have shown my invention as applied to a Smith Premier typewriter, although it is to be understood that said invention may be adapted in whole or in part to other forms of writing machines. 1 4

In carrying out the invention in the preslivery holder or carrier being'mou'nted on a supporting frame secured to the paper carriage truck andthe receiving holder or carrier being mounted on a support secured to the front bar of the platen frame or carrier. The tally strip passes around and under the platen outside of the work or bill sheet and preferably the inner face of it is coatedwith carbon or other transfer medium enabling a separate transfer or carbon strip to be -dispensed with. In the present case the' transfer medium is of two dlfierent colors,

preferably black and red which are dis- .-'posed in stripes longitudinal of the tally stri Provision i's-made for'adjusting the hol ers orcarriers lengthwise of the platen 'so as to bring the fields or stripes of the tally strip in register with the total'and credit columns .on thebill sheet wherever such columns maybe located widthwise of said bill sheet, and so that byoperating the usual printing instrumentalities the item on the tally strip and the corresponding item in the total or credit column of the bill sheet may be simultaneously written. Furthermore, as the Smith Premier machine e1n- .ploys a rocker platen (that is a platen which may be rocked on its support) means are provided for taking up the slack of the tally strip during the return of the platen to normal position after it has been so rocked and also for keeping the tally strip in a taut condition between the carriers or holders. As is well understood it is desirable to .line space the tally strip or move it in the direction of its length a single line space distance'only for each bill sheet, so that the amounts on the tally strip may appear con-' densd or close together. -Furthermore, in styles of billing work in which it is desirable to employ a tally strip it-is also highly desirable to square or aline each bill sheet as it is introduced into the ma chine. I have, therefore, in the present instance provided means for cOnnecting the.

handle or arm which operates the alining or leading edge stop device for the bill sheet with the means for line spacing the tally strip, so that the latter is automatically line spaced each time the leading'edge stop is positioned to cooperate with a bill sheet on the introduction of the latter into the machine.- The line spacing mechanism for the tally strip comprises in the present in stance a ratchet wheel fixedly related to the receiving tally strip carrier and a pawl carrying arm pivotally connected with the finger piece or operating arm for actuating the leading edge stop device and also for releasing the main paper feed roller.

Having thus briefly outlined the main features of my invention I will proceed to describe it more in detail in connection with the accompanying drawings, wherein-- Figure 1 is a front elevation of the platen and carriage of a Smith Premier typewriter having my invention applied thereto, said 'figureshowing the parts in normal or writing position, the front portion of the carriage frame or truck being broken away for the sake of "clearness- Fig. 2 is a left-hand end view, partly in.sect-ion,of Fig. 1. Fig.

3 is a left-hand endview, partly in section, and showing the platen rocked forward to expose the writing. Fig. 4 is a. fragmentary longitudinal sectional view of the delivery tally strip carrier ,or holder and its si1pport.'

Fig. 5 is a sectional view takenon a plane represented by the line yy in Fig. 1 and seen in the direction of the arrowsagsaid line. Fig. 6 is a fragmentary rear view showing parts of the paper feeding mechanism of the machine.

In the drawings, 1 designates the carriage truck or frame which runs on anti-friction.

balls 1, the latter being seated on grooved rear and front track-ways or guide rails numbered respectively 2 and 3, said .guide rails being secured tothe top plate (not shown). A platen 4 is mounted in a platen frame or carrier, consisting of a front rod or bar 5, a rear bar 6 and left-hand and right-hand end or side plates or bars numbered respectively 7 and 8. A platen shaft or axle 9 passes through the end plates of the platen frame and at its end portion bears on the carriage truck or frame 1, the ends 5 of said axle being provided with the usual finger wheels 69. The platen carrier is normally heldin the position illustrated in Fig.

2 by spring pressed hook-like arms 10 and 11 which engage pins or.studs 12 and 13v projecting lat-erallyffrom the end plates-7f and 8. The platen frame and'the carriage truck together constitute a platen car 'iage' which is adapted to be fed step by step for letter spacing in the usual way. The rear I bar 6 of the platen carrier has fixed to it brackets or standards 1 1 to which is secured a paper table 13. Links 15 are mounted on and depend from the rear bar 6, said links at their lower ends being connected to a shaft or spindle 64 having bearings in the links. Short arms 67 fixed to a shaft or rod 66 extend downwardly from said shaft outside of the links 15, as shown in Fig. 6, these arms being connected at their lower ends with the shaft 64. The arms 67 are provided with eyes which receive the rod 66, plmfi seouring said rod andarms 67 in fixed relation. The rod 66 carries a main feed roller 17 which is normally maintained in contact with the platen 4 or. the paper thereon by springs 18 which are secured to the standards 14: at their upper ends and press against the rod 66 at their lower end portions.

$ A stop device or gage for the leading edge of the paper is provided, said stop device consisting of a lip or shelf 20 turned outwardly at the rear from a paper plate 20, which paper plate is pivotally mounted on 5 the shaft 64 and is normally pressed at its forward edge portion against the platenor the paper thereon by the usual paper fingers 21, as shown in 2. From an in pection of this figure it will be apparentthat the leading edge stop 20 is normally separated from the platen and is hence then in an inoperative position. An operating arm, finger piece or releasing member 19 is. fixed to the left end portion of the rod 66 by a pin 19'. The construction is such that when the finger piece. or arm 19 is pulled forward from normal position by the operator the feed roller 17 .is moved backward and the forward portion of the paper plate 20 together with the paper fingers 21 is moved away from the platen. The leading edge stop 20,-however, remains inoperative during this movement of the paper plate 20. \Vhen, however, the finger piece or operating arm 19 is pushed in the opposite direc-' tion or rearward from the normal position, it first operates to swing the leading edge stop 20 into operative position against the platen and next operates to release the feed roller 17 or move it away from the platen. The paper controlling devices comprising leading edge stop and feed roller devices above described form the subject-matter of the patent to A. J.- Briggs No. 813,345, dated February 20, 1906 and it is not therefore considered necessary to describe herein the mechanism or explain its manner of operation in greater detail. -In practice it is com mon when the writing is finished to release.

the written work sheet by pulling the arm 19"forward, thus enabling 'said written work sheet or bill sheet to be readily withdrawn from the machine. Thereafter the arm 19 ,is pushed rearward bringingthe leading edge stop 20 into operative position an releasing the feed roller 17-, this concurrent operation of the stop and feed roller enabling a new work sheet or bill sheet to be readily inserted over the paper table 16 and alined against the leading edge stop 20.

The usual line spacing handle 28 controls a slidable line spacing pawl 29, the latter being adapted to cooperate with the crown teeth of a 'line spacing ratchet wheel 30 (Fig. 1) to enable line spacing movements to be communicated to the platen, with the right-hand end. of which the ratchet wheel 30 is operativcly connected.

Referring now to the novel tally strip devices, these include a delivery holder or carrier for a supplementary work sheet or tally strip, said holder being arranged at the rear of and above the platen and mounted on a support comprising left-hand and righthand uprights or standards numbered respectively 24 and 52, which may be secured at the back of the carriage truck or frame in any suitable manner. For example, the uprights 24: and 52 may be fixed at their lower ends to the tabulating rack bar 70 with which the machine is commonly suplied, said bar 70 being attached to brackets 1, secured to the carriage truck. 'Bearing blocks 47 and -8 are screwed to the upper ends of the uprights 24 and 52 respectively, said bearing blocks supporting a shaft 34. he shaft 34 may rotate within the bearing blocks but is restrained from turning freely by the friction of a coiled spring 49 surrounding the right-hand end portion of the shaft and confined between the bearing block 48 and a collar 50 secured'to the shaft 34 by a set screw 50 (Fig. 4). By moving and setting the collar 50 nearer to the hearing 48 the spring 49 may be compressed to increase the resistance oflered b the shaft 34 to rotary'movement; and, course, by setting the collar 50 farther from the hearing block 48 the resistance. of the shaft 34 5 to rotary movement will be lessened. "A finger button 51 is secured to the end of the shaft 34: outside the right-hand bearing block 48. By pulling rightward on this button the spring 459 may be compressed and the shaft 3 f moved longitudinally rightward so as to withdraw its left-hand end portion from the bearing block 47. tion is such that after being thus withdrawn from the left-hand bearing block the shaft 34 may be swung horizontally rearward, the

bearing block 48 turning on the upright 52' to permit of such swinging movement. W hen thus swung to the rear a continuous work sheet or tally strip wound in a roll may be readily. arranged on or removed from the shaft 3} which is adapted to carry it.

The delivery holder or carrier comprises a tubular part or hub 23 having bushings 32 i and 33 suitabl secured in its 'endsas by screws 44 and 2 being formed with 0 enings through which shaft 34; passes, the tu ular hub 23 surroundping the shaft "and being-adapted,'throu'h the bushings, to turn thereon (Fig. 4).] Tie holder or carrier is constructed to bcrotated' to a limited extent on the shaft '34 and spring means is provided for automatically retracting-the carrier after such limited rotary movement, said movement and auto- 35 matic retraction being for the purpose of permitting the platen to be rocked forward and. backward for inspecting the'writing.

without interfering with the proper operation of saiddevices. Theconstruction by, which the results just referredto are ob-- tained will now be described.

Acollar 35' surrounds the shaft 34 and passes through the bushing 33, said bushing bearing on 'said collar. At its inner end which lies within the tube 23, said collar '35 is provided with a flange 35. The lefthand end portion of the collar 35 extends outside the bushing 33 and is surrounded by a second collar38 which provides a support for a set screw 39, the latter'passing through both the collars 35 and38 and abutting against the shaft 3i thereby'seeuringthe two collars in a fixed relatio'n'witli' sale; h

Thisrelatiomit will be apple.rent,-- be varied both circumferentially nihd leng tudh nally-"of the'shaft. Als'le'e 'e36"is'ai'ranged between. the flange 135F111! the bushing 33. said sleeve having a bearing on thecollar 35 and-being adapted 'jto turn freely thereon.- 60 The sleeve 36 is provided with a lug or pro- -jection 37 which is adapted'topoperatively e age with a Strider pin 40 projecting latera yiinward from the bushing 33 and also with'alstud or pin 41. projecting laterally *5 from the flange '35 and oppositely from the The. construe respectively, said bushings engages the surface of the hub 23.

Preferably, the inner face of the tally strip hub23 ofthe delivery'carrier. At its rightpin or stud 40. The pins or studs {t0 and 41 are of such length that they may freely pass the one by the other when the parts which carry them are relatively rotated. A wire spring 42 is coiled around the shaft 34 within'the tube :23 and has one of its ends secured to the bushing 32 and its other end secured to the flangeBfi. The tension ofthe spring may be adj usted by loosening the set screw 72 and turning-the hub. 23relatively to the 75 bushing 33. This spring tension should be such that when wound up as much as it may be in the operation. of the machine it will exert. a force slightly less than that necessary to overcome the spring 49.

The operation of the'parts described immediately above will presently be explained more at length. I

The tubular hub 23 is provided with a right-hand flange 43 having oppositely dis- 'posedand inwardly .projecting tongues H (Figs. 4 and- 5). The flange 43 is fixedly sccuredto-the hub 23 in any suitable manner as by screws 4-1 passing through the tongues 44 into the tube Y23 and bushing 32. The

hub; also receivesa left-hand flange 45 having-a hub portion Mi -which frictionally The flange 415 may be adjusted at various dis: tances from the flange 43 toaccommodate tally str ps of varying width. The continuous ribbon-like work sheet shown in the present instance is numbered 31 and. will hereafter be referred to as a-tally strip.

O0 is coated with a suitable transfer medium. In the present instance this medium is applied in two colors dividing the inner surface of the tally strip into two longitudinally extending bands or color fields a and b-whichpreferably. are respectively black and red. The tally strip is wound or rolled on a core piece or sleeve 46; the latter being adapted to he slid on-and off the tubular O hand end the core piece 46 is provided with oppositely disposednotches 4:6 with which the tongues 44 are adapted to engage. The construction is such that the core piece 46 carrying the tally strip 31 is forced to turn with the delivery carrier when .the latter is turned. r The free end of-the tally strip 31 is. drawn downwardly from the back of .the delivery carrier. and around the under s'idefofgthe platen, passing outside of'and over the feed roller 17 and the aper late 20, thence passing over the un er an front sides of aguide rod 68 and upwardly over the front and top of the receiving carrier-presently to 25 be described. The guide rod .68 extends.

fromside-tg-sidc ofthe platen in front of and abouton a line with the bottom of the latter and is secured at its ends to standards or brackets 26 and 27 fixed to the front bar upright and extend partly below the frame bar 5 and partly above the latter and that the guide rod 68 is secured at the lower ends of the standards 26 and '27. Near. their upper ends said standards are perforated to provide bearing openings for a shaft 53 on which the forward or receiving tally st-rip carrier or holder is mounted. This receiving carrier comprises a hollow tubular body 25 provided with end plugs orbushings 25* through which the shaft53 passes. A set screw 54 engages a threaded opeuing'in the right-hand bushing 25 and secures the receiving carrier in a fixed relation with the shaft 53. By loosening the screw 54 the receiving carrier may be adjustedlengthwise of its shaft. .The body 25 of the receiving carrier is provided with slots 6:} (Figs. 1 and 3) through which the free end of the tally strip 31 is adapted to be threaded and by which said tally strip is frictionally held in engagement with the carrier.

Referriug 'to the operation of the tally strip spring 42 and its associate parts, it will be apparent that the spring 42, being fixed at its left-hand end to the flange 35, tends constantly to turn the delivery carrier in the direction of the arrow in Fig. 2, thereby, of course, tending to wind the tally strip 31 ,on the delivery carrier. \Vhen the outer end of the tally strip is free or loose, the delivery earrier is checked or prevented from turning beyond a certain point by reason of the fact that the stud or engaging member 40.011 the carrier engaging the lug or engaging member 37 on the sleeve 36 forces said sleeve to -turnwith the carrier until the opposite side of thelug 37 is arrested by the stud or engaging i'ueiuher 41. The stud 41 is fined to the. sleeve which is fast on the shaft 34, said shaft being frictionally held by the spring 49 and the spring 42 not being strongcnough to overcome the friction of said spring 49, hen the free end of the tally strip is drawn downward toward the platen the delivery carrier is turned in the direction of the arrow in Fig. 4; thereby winding up the spring 42 and turning the stud 4-0 away from the lug 37, said lug and its sleeve, of course, remaining quiescent. l'V hen the carrier is turned through almost a. complete revolution the stud 40 will contact with the opposite side of the lug 37 with the opposite side of the stud 41 and thereafter. as "the carrier continues to turn, will force said lug, with the collar 35 and the shaft 34, to turn with it, overcoming the friction of the spring 49 and forcing the delivery carrier, and the shaft 34 on which it is mounted to turn together asa unit. The

relations of the connecting members 40, 37

and 41 during this last described stage are illustrated in Fig. 2.

It will be seen that the construction is such that substantially two revolutions of the delivery carrier may take place independently of the shaft 34 and that after these two revolutions the shaft is taken up and forced to turn with the carrier, the conneeting member or lug 37 serving to provide in effect alost motion connection between the shaft 34 and the delivery carrier. It will also be apparent that before'enough of the tally strip has been drawn from the delivery carrier to enable said tally strip to be fastened to the receiving carrier the delivery carrier will have been turned through more than two revolutions and consequently the shaft 34 will be forced toturn with the delivery carrier. It will further be seen that when the tally strip is attached to the receiving carrier the spring 42 will be -"l'ocker platen style like the gmith Premier typewriter. \Vhen the platen is rocked forward from the position shown in Fig. 2 to that shown in Fig. 3 the delivery carrier and the shaft 34 will be turned together throughv something less than two revolutions, .the devices 40, 37 and 41 being 'rotated to the position shown in full lines in Fig. 2. W hen the writing has been inspected or an erasure'made or whatever the desired purpose was hasbeen accomplished and the platen is rocked back to normal position, the spring 42 will automatically take up the slack in the tally strip, rewinding it on the delivery carrier which will be turned on the shaft 34 in the direction of the arrow in Fig.2, said shaft itself, during this course, during subsequent line spacingmovements of the tally strip the delivery carrier will turn I independently of the shaft until the engaging members 40,- 37

and 41 again are brought into the relations shown in full lines in Fig. 3 after which the shaft 34 will be forced to turn with the carrier. Without the spring 42 and the coiipcrating parts or the equivalent of said spring and parts it will be clear that a tally I strip of-the character described could not be used advantageously with a rocker platen for the reason that each time the platen was rocked forward a considerable length of. the

tally strip would be drawn elf the carrier and when the platen was rocked back to normal position the taken up. The construction is such that when the platen is rocked forward at,.any

time, slack in the tally strip will be taken.

u by the action of the spring 42 when the p aten is restored to its normal position.

As has been stated it is desirablein order to condense the items on the tally strip, that said tally stripshould be line spaced once only for each bill sheet which is written, In the present instance in order to aeconr plish this result I provide supplementary line spacingjd evices .for the tally strip which are operative automatically, when 'the'iirm 19 is pressed or pushed rearward to move the leading edge stop 20 to operative position and the feed roller 17 away from the platen. The supplementary line spacing devices comprise a toothed wheel 56 which is suitably secured to the shaft and is arranged in a slotor recess formed in the upper portion of the standard 26.. A ball detent 57 is supported on a coiled spring 58 arranged in a depression 58 drilled or otherwise formed at the bottom of the recess '60 in-the standard 26 (-Fig.' 2). Said ball detent cotiperates with the toothed wheel 56 to maintain the shaft 53 and the forward: receiving carrier carried by said shaft in desired line space position. The parts are so proportioned that the space between two adjoining teeth of the wheel 56 gives the desiredline space distance between the items on the tally strip. The

' central line of the depression 58" is slightly to therear of the-axis of the shaft 53 sothat the 'ball 57 cooperates with the teeth of the wheel 56 in such'a way that said 'wheelis more easily turn'ed forward than backward, although a sufii cient force exerted on the shaft 53 or pull on the telly strip will enable the receivingcarrier to be turned backward-for any purpose without the necessity of releasingthe ball detent manually. The right-hand end ortion of the shaft 53 has fixed to-it outside the standard 27 a finger button by which the shaft and-the receiving carrier may be conveniently turned by hand, A pawl-carrying arm 59 is pivotally connected at 63 with t e arm 19, said arm 59 extending upward and forward, as

shown in Fig.2, and being oft-set inward,

as shown in Fig. 1, so-that its upper end prevented by the bushing 33 which is adaptportion may enter the recess 60, the latter servingas a guide fora-the arm which may move fOreLand aft of the machine in the recess. The forward end portion of the arm 59 terminates ina hook or pawl 61 which slack would not be.

cotiperates with .the teeth-of the wheel 56 and is held from accidental displacement by a coiled spring 62 which is carried by a cross pin 62 which bridges the upper part of "the recess 60. When the arm 19 is pulled forward to release the feed-roller 17, the pawl 61 is moved awayfrom the toothed wheel 56 so that no movement is communicated to the forward or receiving tally strip or carrier and hence the tally strip itself is not affected. When, however, the arm 19 is pushed rearwardly to operatively position the leading edge stop 20 and move the feed roller 17 away from the platen, the'oijiwl 6.1 cooperates with the toothed wheel 56 to turn the'latter one tooth and so advance the tally strip a single line space distance.

Peferring now to certain features in the manner of using and operating my improvements, when it is desired to arrange a-tally strip roll in place the shaft 34: is withdrawn from its left-hand bearing 47 and I rearward, after which the flange 45 is remo ed and the tally strip roll with its core piece 46 is slipped on the tubular hub 23 and adjusted in pla'cewith the notches 46*" engaging the tongues 44. Then the flange 45 is replaced and the shaft 34 swung forward and caused to reengage in the bearing swung the tension of the spring 42 as has been described so that the tally strip is maintained in a taut condition. Assuming that bill sheets of the character best shown in Fig. l of the drawings and designated by the reference numeral 22 are to be employed, the

operator next introduces one of. said. bill sheets into the machine makingnse preferably of a side guide (not shown) of any desired character for properly positioning the bill sheet lengthwise of the platen. An inspection of-the bill sheet-22 shows it to be provided with date, item, amount, total andcreditcolumns. The delivery and receiving carriers are adjusted lengthwise of their respective shafts 34 and 53 so'that the black field a of the tally strip 31 overlies or is superposed on the total column of the bill sheet and the red field b overlies the credit column of the bill sheet. In adj usting' the rear or delivery carrier lengthwise-of its'shaft 34 it is only necessary to loosen the set screw 39 and move the carrier along to the desired position after which the set screw may be tightened. When it is tightened, the collars 35 and 38 are thereby fixed to the shaft 34 and motio'ii of the de-- livery carrier leftward along its shaft is ed to abut against the collar 38, while motion of said carrier rightward is prevented by the flange 35 against which the sleeve 36 is adapted i. but at its right side, said sleeve at its left side being engaged by the 17, paper plate 20 andleading edge stop 20,

while the tally strip passes outside of the feed roller, paper plate and stop and is separated from the platen at the printing line by the bill sheet 22. Assuming that a bill sheet has been properly introduced and written and that it is desired tojwithdraw it and introduce a new bill sheet, the operator pulls forward the finger piece or arm 19, thereby releasing the written bill sheet from the control of the paper feeding and controlling devices including the paper feed roller 17, paper plate 20 and paper fingers 21'. The written bill sheet may then readily be withdrawn after which the operator presses the arm 19 rearward. This operation positions the stop 20 against the platen and moves the feed roller 17 away from the platen, at the sametime automatically advancing the tally strip so that the total or credit item next printed upon it will be a line space distance below the item last printed on it. With the finger piece or arm 19 maintained in its rearmost position a new bill sheet may be introduced and alined against the stop 20, after which-the arm 19 may be released, permitting the parts to return to normal position and causing the feed roller 17 to engage with the bill sheet. By operating the line spacing handle 28 or a platen finger wheel 69 the platen may be turned in line spacing direction until the bill. sheet is in position for receiving the first item or line of writing. This turning of the platen and ad Vance of the bill sheet occurs without ailecting the tally strip 31. The first and subse quent lines or items on the bill sheetmayv now be printed by operating the usual printing instrumentalities (not shown) causingthe types to make their impressions on the bill sheet through the usual inking ribbon (not shown). The final item to be written on the bill is the daily total or the credit as the case may be, and this final item is printed through the ribbon on the outer or plain surface of the tally strip 31 while simultaneously the transfer medium on the inner surface of said tally strip off-sets on the'bill sheet thereby reproducing the total or'credit item in the-proper column on said bill sheet. Next the'arm 19 may be pulled forward releasing'the bill sheet so that it may be withdrawn from the machine, after which the arm 19 may be pushed rearward,again operatively positioning the stop 20 and automatically line spacing the tally strip. When, in the course of printing the bill it is desired to inspect the-writing, make an erasure or the like, the platen may be rocked forward in the usual way and when it is returned to normal position the spring 42 will take up the slack in the tally strip as has .carrier, may be separated from the unused portion and removed from the machine, to be then taken to the bookkeeping department where it is made use of to check or prove the billing work. It is not deemed necessary to take up in detail this phase of billing systems in which a tally strip of the character described may be employed. I The free end of the unused portion of the tally strip is, of course, threaded through the slots 65, thereby reconnecting the tally strip with the receiving carrier, and the parts are then so arranged that work may be resumed when desired.

While I have described one mode of making use of my improvements it will, of course, be understood that said improvements may be used in other ways than that described and that parts of my invention may be employed without other parts. Various changes may be made without departing from the spirit and scope of my invention.
