WILLIAM ALLAN DYER, or SYRACUSE, NEW YORK; ASSIGNOR TO THE SMITH PREMIER TYPE'WRITER COMPANY, TION OF NEW YORK.

or SYRACUSE, NEW YORK, A com-om- TYPE-WRITING MACHINE.

Patented Feb. 27, 1912.

Application filed June 1, 1909. Serial No. $9,376.

T 0 all whom it may concern:

Be it known that I, WILLIAM ALLAN DYEB, 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 Typerio ing Machines, of which the following is a specification. i

My invention relates especially to What is commonly termed the paper feeding mechanism of typewriting machines and its obj cot, generally stated, is to provide improved devices of the class specified.

To the above and other ends the invention consists in the features of construction, combinations of devices and arrangements of parts hereinafter described and particularly pointed out in the claims.

My present invention is directed to the paper guiding and controlling devices usually called paper fingers and is designed to provide ajconstruction whereby the paper finger contrivan'ces may be readily and cxpeditiousiy removed out of the path of the paper.

My improvements are particularly useful in connection with manifolding work, as

they enable erasures to be mace conveniently on the separate sheets constituting the manifolding packet or set.

In my companion application Serial No. 499,375 filed of even date herewith, I have shown. one means of accomplishing the general object in view by providing a construction wherein th paper fingers are swung laterally on their individual supports or can riers without disturbing the position of said supports lengthwise of the machine. In the present case the result sought for is attained. by swinging the paper fingers bodily, together with the support or rod on which they may be adjustably set, away fronrthe surface of the platen 'or the paper thereon so to leave the paper in advance of the printing line, and for a short distance at the opposite side thereof entirely free to be turned away from the platen sheet by sheet.

My invention is shown as embodied in a- No. 10 Smith Premiertypewriting machine which is a front-strike machine, but the nature of the ii'ivention is such that it may be readily adapted to other styles of writing machines, front-strike or otherwise.

In the accompanying drawings, Figure l is "a front elevation of a platen and a carriage of a No. 10 Smith Premier 'typewrib ing machine embodying my invention and of the upper part of the machine frame on which said carriage is supported, parts being omitted and parts broken away, the machine shown in thedrawings bein of the wide plate style. Fig. 2 is ragmcn tary perspe ive View of one of the paper fingers, Fig. 0 is sleeve coinprisin part of one of the paper linger contrivances. Fig. 4 is a sectional view taken on a plane represented by the line a; in Fig. 1 and looking in the direction of the arrow at said line. Fig. 5 is a view corresponding to Fig. 4; but showing some of certain other parts shown in id Fig. 4.

As shown in Figs. 1 and :he top plate 1 of the main frame of the machine has rising therefrom standards 2 wh' h support a grooved track-way .Anthfriction balls 4 cooperate with the track-way and with the angularly bent. portions of a slide bar 5 connectedto the ends whereof are end bars 6, the end bars and slide bar being comprised in the carriage truck. The platen carrier or frame includes end bars or pieces 7 and 8 connected by frame rod or bar 9. Axle sections 10 extend laterally outward from the ends of the platen l1 and normally rest in seatsor notches 12 in the end bars 6. Studs 13 extend laterally from the end pieces 7 and at the rear of the platen and engage bearing openings in the bars 6. The platen and platen carrier may be tilted upward and rearward on the. studs 13 as pivots fromthe Fig. 4.- to the Fig. 5 position preferably by pressure applied to an extension or finger piece 14: integral with and extend mg upward fronithe left-hand endbar 7. The extent of the tilting movement is limited by a pin 15 extending from the end bar 7 into a depression or slot 15 formed in the left-hand end bar 6 of the carriage truck.

The usual or suitable paper feeding and controlling devices may be provided, s'aid devices comprising a paper .table (not shown) and a deflect-or or apron, the forward portion whereof is indicated by dotted lines in Fig. and numbered 16. Main and secondary feed rollers, numbered respectively 17 and 1S and indicated by dotted lines in Figs. 4; and 5, cooperate-with a perspective View of a the platen, the main feed roller 17 being located at the rear of the under side thereof and the secondary feed roller forward of the 7 main feed roller. The paper controlling de-.

I per thereon and overlying the apron 16 and somewhat above the upper edge of the same.

The parts thus far described are not my in vention but are found in the No. 10 Smith 1 Premier machine.

The end bars 7 and 8 are fprmed with forward extensions numbered respectively 7 and 8 carrying shouldered screws 21 on which'are pivoted arms 22 and 23, said arms extending upward in front of the axis of the platen and terminating at their tops in collar portions 24 and 25. The arms 22 and 23 are connected by a cross rod or bar 26, said rod extending lengthwise of the platen above the same and entering the collar portions 24:

and25 in which the ends of said rod are suitably secured. The rod 26 and the arms 22 and 23 constitute a U-shaped frame or bail which. is adapted to be swung forward and downward on the pivots 21,bl.lt which normally is maintained locked in the position shown in Figs. 1 and 4:. An arm 27 which fits in a depression in the inner face of the left-hand bar G is secured in place by a screw; 28, and said arm extends forward and upward, constituting in effect a part of the carriage truck.- At its forward or free end the arm 27 is bent or oifset inward toward the middle of the platen at right angles to the body portion of said arm as indicated at 29. As shown in Figs. 1 and 4 the bent portion or offset 29 lies in the path of the arm 22 and is normally so close to the front edge of the lower part of said arm that it will prevent forward movements of said arm and of the swinging frame of.

which said arm is a part. This stop 29 a sort of safety device for preventing the swinging frame from dropping and also serves other purposes as presently to be described. Normally, thc swinging frame comprisingtherod 26 is locked or latched in the posit-iodshown in Figs. 1 and i by means ineludinga latch, locking device or catch 30" pivoted at 31' to the inner face of the end j'piece'7. Said latch normally extends "forward from its pivot and is provided witha seat or notch 32 which engages a pin 33flextending laterally inward from the arm 22. A coiledspring 34 arranged between the latch 30 and a hub 7 at-the inner side of and integral with the frame I iece presses the latch 30 upward and maintains the notch 32 normally engaged with the pin 33 as shown in Fig. 4. From Fig. 4 it will be seen that the pivot screw 21 of the arm 22 is forward of the pin 33. Con sequently if the platen be tilted up so as to take the arm out of the path of the stop 29, and then the rod 26 be pulled forward, the pin 33 will rise slightly, depressing the forward end portion of the latch or catch 30, thus unlocking the swinging frame and en abling it to be swung forward and down to the position shown in Fig. 5. The frame will be arrested in this position by the an gagement of a V-shaped notch 35 cut in the forward edge of the arm 22with the upper edge of the stop or off-set 29. The construction'is such" that when the notch 35 and stop 29 are engaged not only are the arm 22 and the frame of which it constitutes a part held from further downward movement but the platen and platen carrier are also held up or locked in the tilted position shown in Fig. 5, the swinging frame forward of the part 29, together with the devices on the rod 26, acting as a counter-weight to the platen and preventing it from. dropping back to normal position under the influence of gravity.

When the latch30 is freed from the pin 33 its upward movement under the pressure of the spring 34 will be limited by the engage ment of a tail piece 30 on said latch with the hub 7 as shown in Fig. 5, so that when the swinging frame is restored to normalpd sition the pin '33 will, engage with the top face of the latch 30 forward of the notch 32 and will. depress said latch far enough to enable said pin 33 to re-seat itself in said 7 notch and thus re lock the swinging frame in normal position.

The rod 26 supports one or more paper controlling or guiding devices or paper finger cont-rival'lces, there being two main contrivances shown in the present case which are adapted'preferably to cotiperate with the side margins of work sheets. In addition there may be provided a smaller or secondary guide finger which ordinarily is arranged about midway ofthe length of the platen. These contrivances are slidably supported on the rod 26 and cooperate with the front or printing face of the platen.

l lach of the principal paper finger con trivances has a sleeve 36 which is shown detached in Fig. 3, said sleeve 36 being depressed longitudinally to form an internal fin or feather 37. The sleeve 36 surrounds is arranged between parallel arms 39 which are art of a vU-shaped member (Fig. 2). Sai member further comprises a cross piece 40 connecting said arms, the latter.

ing cut out as indicated at 41 to fit over ithe rod 26. One of the cut outs 41 is provided with an inwardly projecting pointed rotary movement of the Wrod 26 may take place. to the under face of 515i sists merely 29 one end of whichfis securedto 'the sleeve; the

side of. the platen and overlies the scale or Coiled arohnd the sleeve pa'per-plate 19. ,136 between the arms ,opposite end of said" spring engaging the 11 away a short cross piece and tending constantly to press the paper finger against the front face of the platen. The spring pressure is transmitted by the lower endof the paper finger to the scale or'paper plate 19.311d normally maintains said scalein contact with thepaper thereon as" shown in vplaten or-the ig. at; The

ista'nce'from the face of the platen and on the rod 26 as a pivot against the spring 44, the rod -26 remaining mot-ionvless. 'Thism'ovement of the paper finger as also its sliding movement along the rod 26 his entirely distinct from the; bodily swing ofthe paper finger 26,..as hereinafter described, during which bodily swing thefrelationship between the rod and the paper finger is not varied. I

40 do not claim per 86 the specific construction of paper finger contrivances abovev described;- finger oontrivance as herein used are broad and are intended to include such devices as control and guide the paper after it leaves the printing point.

One of the paper finger contrivances just described may be and preferably is arranged to cooperate with'the margin at one 0 side of the paper-while the companion contrivance is similarly-arranged at the opposite. margin, the sleeves 36 being controlledby the arms 39- between which way between these guides or fingers and on the rod-26 may be arranged a short central auxiliary guide fin er which, as' here shown, is formed 0 F a st'ripof sheet metal which is bent topartially embrace the rod 26 and is provided-witha paper guiding. :portion' which extends downward and forwardat the front side oft-he platen-some 'diatanoeftoward the scale plate 19; The .frictionai engagement between the looped Q6 orpi r -qf the short finger 45 and the'r'od' aper' finger may be swung together with the "rod.

The terms paper finger and paper the lengthwise-- movements of they 'are confined. Mid-' 26 is sufiicient to maintain saidfinger 45 in adjusted positions. The friction between the guides or fingers 43 and the scale-plate 19 due to the pressure from the springs 44 assists to maintain the main paper finger contrivances or guiding devices in adjusted positions.

As has been stated, my invention-is especlally adapted to facilitate erasures in manifolding work. Sup osethat the marginal guides or paper nger contrivances have been adjusted on the rod- 26 to correspondwith. the width of the .paper to be written on and that a manifolding packet or set of papercomposed of an'inner sheet a, outer sheet c, be introduced intothe -machine at therear;

platen ween the-same and the feed. roller "17; thence; being guided tothe feed roller 18 by the deflector 16,. and passing upward between the scale 19 after which the packet is brought intocoii'peration with thepape'r finger contrivances.

As the writing takes-place and the sheets are advanced together line by line in the usual or any suitable way, the leading edge portions of the sheets. will. the front side of the platen vand will-be guided by the paper fingers or guiding devices backward under- 26 as-shown in 4. are in the Fig. 4' position-and it be desired to make an erasure; Eben the platen and plat'en" carrier are first tilted upward and back by pressure on the finger piece 14 after A which the swinging frame or bail is released, preferably by pulling forward against, the rod 26, and is lowered to the Fig. 5 position in which, as will be recalled, itis arrested by the stop 29 while at the same time the tilted position, thus leaving both hands of the operatorf'free to handlethe paper. As the swinging frame is lowered it of course carries witli'it the paperfinger contrivances which are thereby' bodily removedforward and downward away from .the printing face or front face of the platen; As the paper finger contrivances are swungaway from the platen; the. pressure which they exert normally against the scale or paper plate 19 is lessened, permitting plate to move v forward and slightly downward away from the platen and the paper thereon so that when vthe paper finger contrivances are finally arrested, the plate 19 will be held by the-end portions of the parts 43 at some distance away from. the front face of the platen as shown in Fig. Obviously with the parts in the Fig. 5 position, the portions three sheets, a carboninlay b and an The. packet isadvanced over theitpaper table and down behind the pass upward at platen and, =the,-papcr plate or the supporting rod S .1.1ppose the sheets platen is locked up in its .of the sheets above the front upper edge of the deflector or apron 16 are entirely free lationship shown in said figure it will beapparent that the printing line on the un dermost sheet a will be exposed so that an erasure may readily be made in the printing line against the platen as a backing. After such erasure the carbon inlay b may be turned upward and backward against the sheet a and then a protecting or backing sheet may be introduced directly behind the outer sheet 0 so that the corresponding erasure may be made thereon. Thereafter the backing sheet may be withdrawn, the sheet 0 replaced, and the swinging frame and associate parts restored to normal position and locked therein by proper pressure applied to the rod 26.

It will be seen that in my present invention the different sheets of a manifold packet or set may be freed for any desired purpose without the necessity either of turning the'platen and paper forward and backward or without moving the paper finger contrivances laterally to new positions and subsequently re-adjusting them in, the old i Therefore to free the advanced portion of the paper so that it may be expeditiously handled,'in a construction like the present one it is not alone sufiicient to move the paper finger contrivances but the supporting rod also must be moved out of the path which the paper follows when it is drawn away from the platen surface.

It will further be understood that paper finger contrivances of different constructions from those shown and which mayor may not be off-set may be made use of by my present inven tion; that the support for the paper finger contrivances may be varied so long as said support is caused to swing or otherwise move and thereby'to be itself carried along with the paper finger cont-rivances out of the path of the paper, enabling the same to be freely pulled away from the platen surface; that. the paper plate or scale may alsobe differently controlled to move somewhat away from the platen; and that in some instances it may not-be necessary to provide for movlng said paper plate.

By my present lnvention I combine with the'platen of a typewritingmachine a sup port having an unvarying normal relationaper guide on said support, and means or moving said support away from the printing face of the platen,

said means in the present instance comprising the pivoted arms 22 and on which said support is mounted; that locking means comprising a spring catch normally secure said support in a fixed relationship Wit-h said platen carrier; that said locking means are releasable to permit bodily movements of said support in said paper guide; that in the present instance said support is a rod extending longitudinally of the platen and above the same, the platen being that of a front-strike machine; that the paper guide in the present instance is a paper finger which is adjustable along said rod or support and which cooperates with the paper to guide it under said support and be tween the same and the platen; that the sup port and the paper guide move entirely away from the front face of the platen, thereby leaving free and unobstructed the printing face of. said platen upward from a point belowthe printing line; and that the supporting rod and the means for moving it or the arms which carry it constitute in the present instance a swinging frame or pivotally supported bail which is rotatable on its pivot downward and forward to carry the paper fingers downward and forward below the printing line on the platen.
