Specification of Letters Patent.

Patented Feb. 15, 1910.

Application filed July 13, 1906. Serial No. 325,989.

T all whom it may concern:

Be it known that I, GEORGE A. Sims, 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 TypelVritin'g Machines, of which the following is a specification.-

My invention relates to means for doing what is known as condensed record work and has for its object to provide improved devices for facilitating such work in typewriting machines.

To this end the invention consists in the features of construction; combinations of devices and arrangements of parts hereinafter described and particularly pointed out in the claims.

I have illust ated my improvements as applied to the Monarch front-strike typewriter but it is to be understood that the invention may be adapted to other forms of writing machines.

In carrying out my invention in the present instance I provide a detachable supporting member or shaft which is journaled on the supporting arm portions of the usual and ordinary paper fingers mounted on the carriage of the Monarch typewriter, said shaft being held from endwise motion but not interfering in anyway with the regular operation of said paper fingers. The shaft is rotatable on its axis and is provided with a spline which cooperates with springs on the regular paper fingers, whereby the shaft may be maintained in either of the positions to which it may be turned. Supported on the shaft and adjustable lengthwise thereof are one or more auxiliary or supplementary paper ilingers, preferably two, one arranged at each side of the printing point and betweenit and the'regular or terminal paper fingers. By turning the supportingv shaft,

the auxiliary paper fingers may be swung into or out of operative position without affecting the regular paper fingers.

My invention is preferably employed to facilitate the execution of that style of commercial work commonly known as condensed record billing wherein as the bill is written a duplicate is written on a record or sales sheetthroiigh an interposed carbon sheet. Preferably the regular or terminal paper fingers are arranged to cooperate only with the record sheet and the carbon sheet,

also being shown.

A fresh bill sheet may be inserted at therear of the machine and pushed around until it is in position for writing the first line, 1

whereupon the feed rollers may be again brought to operative position and the auxiliary paper fingers swung down to cooperate with the fresh bill sheet. Thereafter during the usual line spacing movements the bill sheet and the carbon and record sheets will be fed together through the machine and the items of the new bill will be reproduced on the carbon sheet close to the last item of the reproduction of the immediately preceding bill.

While I have thus briefly outlined the pre-- ferred method of using my improvements it will, of course, be understood'that the invention may be used in other In the accompanying drawings, Figure 1 is a full sized frontv ew, partly in section and with parts broken away of the carriage of a typewriting machine embodying my i11 vention. Fig. :2 is an enlarged perspective view of a part-hereinafter termed a locking or retaining arm or bracket. Fig. 3 is an enlarged detail sectional view showing one of the supporting arms and he shaft on which it is mounted, the section being taken on the plane represented by the line as in Fig. 1 and looking in the direction of the arrow at said line. Fig. 4 is an enlarged transverse sectional view taken on the plane represented by the line y-g in Fig. 1 and looking in the direction of the arrows at said line, parts of the machine not appearingin said Fig. 1

Fig. 5 is a View corresponding with Fig. 4 but showing some of the parts in the differentrelations from those in which they appear in said Fig. f and omittingasome of the parts appearmg in the latter figure. Fig. 6 is an enlarged perspective view of a part hereinaftertermed throiigh openings in a an auxiliary orsupplcn'ientary paper finger and lts supporting member or shaft.

In the crawings, 1 indicates the top plate of the machine, and 2, brackets (only one of which is shown), fixed on the top plate, said brackets having oppositely grooved track-ways 3 secured to them by screws ,4. Antifriction balls 5 cooperate with the grooved track-ways and with oppositely rooved ways in a rear or slide bar 6. Proecting forwardly from the ends of said slide bar are horizontal end or side bars 7, said side bars being rigid with the slide bar and comprising with the latter a platen frame, carrier or carriage. A cylindrical platen S is-journaled in theside bars 7 and is operatively connected at its left-hand end with a line space ratchet wheel 9 cooperative with which is a pawl 10 pivoted at 11 on a crank arm 12 and'operative bya crank arm or line space handle 141-. The line space handle 14 when properly actuated causes the pawl 10 and ratchet wheel 9 .to cooperate in a known manner to turn the platen on its axis'through one or more'units of line space distance. In addition to the line spacing mechanism thus briefly described it is to be understood that the usual detent mechanism-(not shown) is )rovided, said detent mechanism cooperat-v mg with the line space ratchet wheel 9 to prevent overthrow of the platen in the turn: ing movements thereof and to prevent accidental displacement of the platen from the line space positions to which it may be successively turned and that the usual finger wheels are provided at the end of the platen shaft.

Pivoted at 15 in lugs 16 projecting forwardly from the rear bar 6 are downwardly and forwardly extending arms17 in which are journaled a shaft18 carrying the main feed roller 19, said roller in the present instance comprising number of sections. Pivoted at 20 in tl1e lower-.-ei1d portions of the arms 17 are small wheels 21 which are adapted to cooperatewitlnarms 22 pivoted at 23 in the lugs 16, said arms-at 'their for- Ward end portions carrying a; feed roll'shaft, 24: on which is mounted one qrmore auxiliary feed rollers Springs--26 secured to the}, hanger arms 17 cooperateavith fi ged abutme'nts 27 to maintain the feed roller 19 normally in cooperative relation or contaet with the platen, while springs 28 secured 'to the hanger arms 22 tend to maintain the feed rollers in cooperative relation 01- contact With the platen. The feed rollers protrude paper apron 29 which extends from side to side of the machine beneath and at the rear of the platen and is provided with end portions 30 WlllCll are coiled or hooked around a shaft 31 'journaled on the brackets 16 and in the'side bars 7 of the carriage, said paper apron being thereby pivotally connected with the shaft and being Projecting oppositely release the paper feedin carries with them the springs cameos maintained normally close to the-platen as shown in [*ig. -.l: by flat springs 32 secured on the hanger arms i The paper feeding and guiding devices and'the' line spacing mechai'iism thus far described are substantially the same as the corresponding parts of the Monarch machine and it is not thought necessary to describe them in greater detail. Said paper feeding and controlling-devices may be moved away from the platen and thereby rendered inoperative, by any suitable means, that shown in the drawings and which I prefer to use being the invention of H1 H. Steeleand d3. scribed and claimed b him in a. pending application to which re erencemay be hadfor a fuller description than that given below. from the shaft 31 above each hanger arm 17 are lugs 33 and 34 and projecting upwardly and forwardly from eacli of said hanger arms 17 is a lug 35' which is cooperative with the forward lug 33 of each of the pairs of lugs on the shaft 31. At the left-hand end of saidshaft a finger lever 36 is fixedly secured, said finger lever operating when pulled forwardly to, turn the shaft and cause the lugs '33 thereon to cooperate with the lugs 35 on the hanger arms 17 to temporarily release or render in operative the main and auxiliary paper feed rollers and to swing the paper apron away from the platen, the parts remaining in released position as long as pressure is exerted to hold the lever 36 forward. In "order to devices and'maintain them locked in the inoperative v osition the release lever 36 is pushed back rom its normal position shown in Fig. 4 tothe position shown in Fig. 5. The backward movement ofthe lever 36 rocks the shaft 31 rear wardly and causes the lugs 34 thereon to ngage theihanger arms-17 and swing them downwardly about their pivots 15, thereby swinging the main feed roller away from the platen to inoperative position as shown in Fig. 5. The downward swinging movement of the arms 17 causes the rollers 21 at the thereby rel'eas i flhe downward movement of the arms 22 A 32 with the resnltithat the paper apron is relieved of the pressure of said springs and swings down wardli about the shaft 31'as a center and away from the platen to the position shown in Fig. 5. As will be understood from a consideration of Fig. 5 the parts are so pro portioned that when the release lever is swung to the rearward position the flat face 3st of each lug 3+1 will have been turned so that it is in engagement with the upper faceof the associate hanger arm 17, the lugs 34 serving to lock the parts in the position shown so that said parts will remain inoperative after the hand of the operator is removed from the release lever 36, thereby operator free to.

leaving both hands of the adjust the paper or work sheet, to remove'it, or to enter a new work sheet in the machine, said work sheet as is well understood passing down over a paper table 37 (Fig. 4) at the rear of the platen, thence over the paper apron 29..and between the platen and the feed rollers and thence upwardly at the front of the platen where it may be guided by suitable paper paper fingers, each of said fingers comprise ing an off-set guiding portion 38, a feed roller 39 and a supporting arm 40 on which said guiding portion and said feed roller are pivotally supported. These paper fingers are not claimed by me herein but form the subject-matterof another application wherein they are described at length. As will be more clearly understood from what follows, I prefer in the present instance to employ these paper fingers z s teri'ninal paper fingers to cooperate with a comparativelywide work sheet such as a record or sales sheet and to permit a narrower sheet such as a bill sheet to pass between them without being touched orcontrolled by them. The rear end portion of the supporting arm 40 of each paper finger is provided with a laterally cxtend ing hub 41through which passes a supporting rod or bar 42, said bar being secured in lugs 43cxtending upwardly from the side bars 7 of the platen carriage, headed screws 43 cooperating with the supporting rod 42 at its ends and serving to retain said rod in position; v

Referring now to my novel paper feeding devices, as best shown in Fig. 3,'the top of the supporting arm 40 of each of the paper fingers heretofore described is cut awayor depressed forwardly of the rod 42 as indicated by the numeral 44. A supporting rotary member or shaft 45 is seated in the depressions 44, said depressions serving as bearings for the shaft which lies forwardly of and parallel with the rod or bar 42. Said shaft is formed or provided with a spline,

feather or lateral projection or rib 46 extending throughout its length and) is re-' tained in its bearings 44 by fiat spring members 47, each of which is secured to the top of its associate arm 40 by means of a headed screw 48 and a pin 49, said pin. serving to prevent rotary movement of said spring member 47 about the screw 48 a center. The springs 47 extend forwardly and horizontally and their free ends are adapted to bear against the shaft 45 and against the spline 4G thereon. As shown in F ig. 1 the right hand end portion of the shaft 45 is formed with a circumferential groove or depression 50 which cooperates with the for ward end portion of a looking or retaining controlling, devices or arm or bracket designated as a whole by the angles as shown at 53 and at the inner end of the off-set portion 53, said arm is again bent forwardly at right angles, the forward end portion of the arm being provided with a slot 54 which serves tobifurcate said arm,

forming fingers 55 which engage-avith the groove 50 in the shaft 45. The construction is such that said shaft may turn or'mtate freely but is held from longitudinal l1l()\O-' ment. The shaft 45 serves as a sup :-ortiug member for one or more auxiliary or supplementary paper controlling devices or paper fingers, two of such paper fingers being shown in-the drawings,- they being alike in construction and best illustrated in Fig. (3.

Preferably each of the auxiliary or supplementary paper fingers is formed of a single piece of sheet metal and comprises a .body portion 56 terminating at its lower end in a controlling part or finger proper '57 and at its upper end in an angularly disposed finger piece 58-. .Ears or tabsoQ are bent up at right angles to the body portion of the finger, said ears being perforated as indicated at 60 to permit the passage therethrough of the shaft The spline 46 on the shaft passes through a notch (31 in each ear 59,--said notch joining the main perforation 60. The notches are wider than the spline 40 so that the paper finger may have a slight rotary movement on and relative to the shaft 45. Secured to each of the auxiliary paper fingers in any suitable manner, as by rivets 62, is a spring arm or tongue (33, the free end of said spring arm cooperating with the shaft 45 and the spline 4G thereon and serving to press the associate auxiliary paper finger against theplaten when said fingers are in operative position. The springs 63 also serve as frictional means for retaining the associate auxiliary paper fingers in any desired position longitudinally of said shaft 45. The construction is such that the auxiliary paper fingers may be readily slid along the shaft 45 from side to side of the machine and toward or from eachother and maybe retained in any d'e- Y .auxiliary or supplementary paper fingers n and in the other case on and its spline at two points "auxiliary paper fingers to-operative post- &

The shaft is maintained in either of the positions shown in Figs. 4: and by the springs .47, said spring in one case operating "one side of the spline' lti to turn or the shaft 45 inone direction forrdly, for example, as shown in Fig. l the other side of said spline to turn the\shaft 45 in the oppo site direction, the pressure exerted by the operator causing the spline as it turns to lift the springs 1 :7 against their inherent tension. It will he understood from a consideration of Figs. t and Frtliat the spring members Jere double acting and that ac- .*ording as the point of contact of said spring members with the spline alt; is at one side or the other'of a vertical plane passing through the center of rotation of the shaft to. said springswill tend to turn or rotate said shaft one 'way or another until the springs contact with the surfaceof the shaft. proper. 'hen this contact occurs each of the springs will be in contact with the shaft. or in two lines l the shaft 45 will be. arrested. "he parts are, so arranged that when the -h-att if) is turnpd forwardly to bring the tion, said fingers contact operatively with the will have been turned far auxiliary paper platen before the shaft 45 comes to a state of rest. During the final stage of mow. ment of the shaft if) the springs (53 are slightly flexed and the spline to is arr "ted in a position intermediate side wallsof the. notches 61 '(Fig. i). Ctinseqitently the auxiliary paper fingers-are pi essed ihto operative contact:f \\'ith the platetf, eatli by'its spring or), thush-eceiving individual springmachine in tlltlTliOPGl' order'and fed around pressure. and are capable of sliglit ,'ind'ivid-- ual rotary movements to compensateyfor inequalities in the work sheet, etc. l -)uring the rearward turning movement of the shaft to. the contact or engagement of the springs -l-T with the sitrface of the shaft proper at the other side of the spline takes place wnen the auxiliary paper tingers'ha e been swung upwardly to the position shown in Fig. 5 where they will be in a natural position of rest. At this time, it will be understood, the rear walls of the. notches til are main-' tained against the rear face ofthe spline it) by the springs (33. If desired, of course, the

It will be seen that the double acting springs 47 serve not only to maintain the fingers inraised or lowered 7 5 serve to maintain the shaft Said shaft and the paper fingers thereon may be readily removed by pulling it forwardly and slightly upwardly against the pressure of the springs 0 i7 and may be as readily reinserted in place on the main or terminal paper fingers, care being taken in the latter instance to effect a rengagement between the fingers and the circumferential groove 50 in the. g5 right-hand end portion of said shaftf 'f" Referring now to the operation of my improvements, as I have stated I prefer to em ploy them in condensed'record billing, in which, for example, it may be'desired to write each bill on abill sheet (1 (Fig.1) and at the same time to write a carbon copy 0' such bill on a record or sales sheet b through a sheet.- of carbon paper 0 interposed between the bill and record sheets. From an inspection'of Fig. 1 it will be noted thatthe bill sheet. a is narrower than the record and carbon sheets I) and 0. Themain or terminal paper fingers are adjusted on the rod or bar 42- sofar apart that they will. 60- operate only with the side portions of the record and carbon sheets, the bill sheet a passing between the main paper fingers and not being affected by then Said main or spline most purposes position but also 45 seated in its bearings.

terminal paper fingers, it will be understood, 5 ma y be readily slid lengthwise of the rod l but are so constructed that they cannot turn on said rod, and the rod itself is held from turning on its supports. The auxiliary paper-fingers are arranged to cooperate i with the side portions of the bill sheet a as shown. a. a

All three sheets are mtroduced late the line on the bill theoperator may operate the line'spacing mechanism to bring a fresh line of the record sheet to the printing position. '.l.hereafter the release lever 36 1s pressed rearwardly to move the paper feeding and guiding devices at the rear and lower side erative position as blll sheet a will now be free from all the paper guiding and controlling devices and of the platen from the operative positions shown in Fig. 4 to the inoperative positions shown in Fig. 5. By pressure exerted on the finger portion 58 of one of the auxiliary paper fingers, the latter, together with their supporting shaft, may be turned up to inopshown in Fig. The

may readily be pulled out or withdrawn from the .machine.

.writing the first line.

bill sheet at having turned down to coiiperatewith said bill sheet controlled thereby again and the release lever 36 may be pulled forward to render the paper operative. The

- second bill sheet may now be written andthe matter thereon reproduced-through the interposed carbon sheet on the record. sheet, after which the second bill sheet may be Withdrawn and a third and succeeding bill sheet written in the manner hereinbefore described.

.It will be seen that by my invention there is no necessity of alternately turning the platen forward and back 'in operating the devices and thatthere are no indices or calculations necessary to'operate the devices so that the mind of the operator is freed from thetaxation ordinarilyineurred in operating condensed billing mechanism.

Various changes may be made without departing from the spirit and scope of my invention.
