TYPEWRITING EIACHINE.

Application'- ledvOctober 16, 1922. Serial No. 594,689.

To ZZ 107mm '25 may colare/vt.' p

-Be it known that HERBERT E. BRIDG- wiiricin citizen of the United tates,V and re ident of Syracuse, in the county of @non` daga and State of New York, have invented certain new and useful improvements in rilypewriting Machines, of which the following is a specification. i.

' My invention rela-testo typewriting and like iacliinves, and more particularly to paper feeding means for such machines.

' The object ofthe invention, generally stated, is to provide a simple, inexpensive and highly efficient paper feed device which my be readily shifted to effective or ineffective position as may be desired, and by the mere act of thus shifting the `device bringing into4 action means for effectively holding the device `in either of such positions.v Y l "Stated more specifically, an object of the inventionis to provide a simple and edective auxiliary vpaper feedor pressure device which may be maintained underV spring pressure against the front of the platen or the paper thereon, and which, when it is desired to dispense withr the use of such device, may be readily shifted to a position. at a considerable distance away from the platen where it may be maintained free from interference with the vwork sheets.`

To the aboverand other ends which will hereinafterv appear, my invention consists in the features of construction, arrangeinentsof parts and combinations of devices set forth in the following description and particularly pointed out in the appended claims. i v

In the accompanying;drawings, wherein like reference characters indicate corresponding parts in the different views.

Figure l is a fragmentary top plan VView of 'a portion of a typewriting machine equipped with the paper feed device of my invention.

Figure 2 is a detail fragmentary vertical fore-and-aft sectional view of the same, taken on the line 2,-2 of Figure l and looking in thedirection of the arrows at said line.

Figure 3 is a view corresponding to Figure 2 except that the paper feed-device is shownin side elevation instead of in sectionand is shown retractedtothe 1neffective position.

n purpose.

Figure 4 is an enlarged detail transverse sectional view of the paper feed device and some of the associated parts, the section being taken on the line 4 4; of Figure 2 and looking in the direction of the arrows at said line.

I have shown my invention embodied in the present instance. in a Monarch'typewriting machine equipped for use with Wahl l adding mechanism, Ysaid machine embodying inventions of Frederick A. Hart, Serial No. 630,226, filed April 6,' 1923, although the paper feed device of my invention vis not restricted to its use in such a machine but may be employed in various makes of typewriting or like machines..

In the accompanying drawings I have shown only so much of the machine referred to as is necessary to arrive at an understanding of my invention in its embodiment therein. p

he typewriting machine comprises the usual carriage l supporting a platen 2. Side arms 3 are iixedly secured by suitable means to each end of the carriage. The means employed in the present instance are the same as those disclosed in the patent to Herbert H. Steele No. 1,222,694, dated April 17, 1917.

Parallel cross bars i have their feet 5 secured by screw bolts 6 and nuts 7 to the arms 3. These bars extend throughout the length of the carriage in front of the platen and are united at different points throughout the length thereof by shouldered spacing pins or members 8 riveted at their ends to the ,cross bars, as indicated at 9. As far as the present invention is concerned, these parts constitute portions of the typewriter carriage. 0

l utilize the cross bars 4 to support the paper feed device of my invention, although other supporting, means connected to the carriage may be provided forthis Arranged about centrally of the carriage is a shouldered spacing pin or member l() which preferably isV connected at its Vendsto the cross bars 4 b-y headed screws jio l iisY or supporting portion. 13 thereof is arranged abovetand extends fore-andati;Y of the nia- `chine beyond the cross bars et. The side edges 14 of the supporting portion 13 are parallel and a centrally arranged slot 15in the part 13 extends longitudinally thereoi'.VV

A sheet metal carrier or slide, designated as al Whole by the reference numeral 16, isv riormed at opposite sides with downwardly extending inwardly bent ears or lugs 1T that embrace the sidesV of, thesupporting bracket and guid'ethe back partof the slide in itsY movement on the bracket fore-and-aft ot tlieniacliine, and with similarly bent ears 13 forV they sainevr purpose Vat the Viront end of said slide.

The ears 18, cto-acting With the forward looped end 19 of the bracket limit the forivard inotion'of the slide, as Will be under.A

stoodfrom an inspection. of Fi'g.,3. .Hoiv.

Vever, the rear looped portion 19a of .the bracket of reduced Width, as indicated in Fig.j1.,'so that the ears` 17 may pass said looped. portion Without arresting the rearjwardV motionfofthe slide. Such motion of the slide is limited only by the co-operation.

*Y oiitliefeed4 device or roller carriedbyvthe slide coacting with the platen, as Will herev .inafter appear. lThe slide is preferably pro- ,videdl with a finger pieceito facilitate its movement either vto the effective position shoi'v'nzin Fig; 2 or to theinel'ective position lsliownin Fig., 3. In the present instance aV finger piece 20 isriveted at 21 to the slide and projects upwardly therefrom where itis readily accessible to the operator. The slide isjformed at its rear side edges with downV` ivardly bent parallel supporting arms 22 f 46 which carry between their rear ends a suitable paper ieed. device, in the present instance in. the form oit a feed roller 23.V rl`his rollerV isjournaled on a pivotrpin` 24kV supported at Vits ends in openings in the arinsVV 22'ai'id riveted against displacement there-.-V from. .From what has been said, it will be understood that the'oiily appreciable move:

. nient that the slide has independently ofits movement With-the carriage is a movement tore-and-aft of the machine or transversely ofthe platen -fromthe position shown in Y Invorder Vthat the slide may beretained indefinitely under spring pressure in its effective position shown inFig. 2, or may be retained indefinitely iii its retracted or ineffec-V tiveposition shoivn in Fig. 3, I provide the 'following means; Y, The pin10 has afguide slot 25 to receive an arm or controlling inember 26. One end of the arniis pivoted at 27 in this slot4 so that the armY which extends up above its supporting member or pin -10 Ymayswing *onfitsA pivot fore-andjaift' of the machinev from the position Vshown in Fig.V

2 to that indicated in Fig. 3, and vice versa,

A contractile spring 28` isrconnected at one i Y" end to the arinfZG and at itsA other eiidto a'- pin 29 riveted to'the looped Vend 19a*V of the:

bracket. The orceot thisispringltendsto move the arm 26 rearwardly from the Fig.

3 to thev Fig. '2 position. Theupper Vend ot .Y

the arm 26 V'extends through the slot 15in thebracket and, when the parts are inthe positionindicated in Fig. 3, bearsupvvardly 'against' thebottom of the slide sothat the force of the spring 2S is at'this time exertedV upivardlyon the slide, tending tolioldrit by friction in. the retracted positiom When,

however, the `operator desires .to Iuse VYthe i paper `feed de .v'iceit' is merely Vnecessary'Yto .grasp tlieiiiigei'piece 2O vand move Athe slideV rearward. Tliis -nioveine'nt is continueduntil the 'forward edge 30 otthe'slidepasses upper end ot'the arm 26S .Vlien thisoccurs the arin 2G will bear against saidfioiyvard edge instead of against the bottom .oiithe Vslide and Vthe 4lorce ofthe spring Will Y Y then be exerted endWise'against-:the slide,

Various changes may be made without departing from my invention as it is defined in vthe accompanying claims.

What I claim as new and desire to secure by Letters Patent, is

l. In a typewriting or like machine, the combination of a platen,'a carrier mounted to slide towards and away from the platen, a paper feed device carried by said carrier, and a spring pressed pivoted member coacting with said carrier and automatically operative to hold it under spring pressure in either its projected position of use with said feed device bearing against the platen or in the retracted ineffective position depending on which position the carrier may be shifted to by hand.

2. In a typewriting or like machine, the combination of a platen, a carrier mounted to slide towards and away from the platen, a paper feed roller 'carried by said slide, a spring', and meansY for directing the force of said .spring either endwisey on said carrier or transversely thereof jas may be desired, thereby holding the carrier under spring pressure in either its effective or ineffective position.

3. In a typewriting or like machine, the combination of a platen, a carrier mounted to slide towards and away from 'the platen, a paper feed roller carried by said carrier, an arm pivoted on a relatively fixed part below said carrier and co-acting either with Y the bottom or with one end thereof depending on the position to which the carrier is moved relatively to saidarm, and a spring connected to said arm.

l. In a typewriting or like machine. the combination of a carriage, a platen, a fixed support on the carriage, Va slide mounted on said support for sliding movement towards and awa-y from the platen, a paper feed device carried by-said slide and movable therewith into and'out of position of use, and a spring pressed controlling member co-actwith the slide to exert a lateral pressure thereon when the slide is moved out of position of use and to exert an endwise pressure on the slide wnen the latter is in position of use.

5. In a type-writing or like machine, the combination of acarriage, a platen carried thereby, a fixed support on the carriage, a slide mounted on said support for movement fore `and aft of the machine and into and out of position of use, a paper feed roller carried by said slide and movable by the slide into and ont of contact with the platen, and a spring pressed controlling member that automatically exerts a pressure on the slide either transversely of the path of its movement or in the direction of its path of movement depending on the position to which said slide is moved by hand. 6. In a typewriting or likeV machine, the combination of a carriage, a platen carried thereby, a. sheet metal bracket detachably Xed to the carriage, a sheet metal slide mounted for sliding movement only on said bracket into and out of position of use, a paper feed device carried-by said slide at 'one end thereof and moved by the slide into or out of contact with the platen depending` on the direction in which the slide is shifted, a spring, and means for directing the force of said spring either endwise or laterally against the slide depending' on the position to which it is moved by hand, whereby the force of the spring` is directed at one time to press the paper feed device against the platen and at anotherl time to hold said device away from the platen.

7. In a typewriting or like machine, the combination of a carriage, a platen carried thereby, a bracket secured to the carriage and extending transversely of the platen, a carrier mounted on said bracket to slide thereon towards and away from the platen, a paper feed device carried by said carrier and moved thereby into and out of contact with the platen or the paper thereon, a spring, and means whereby the position of the carrier automatically directs the effective force of the spring` either to force the feed device against the platen or to hold it away from the platen in its retracted position.

8. In a typewriting or like machine, the combination of a carriage, a platen carried thereby, a yoke-like sheet metal bracket secured at its ends to the. carriage infront of the platen and extending fore-and-aft of the machine, a carrier mounted on said bracket to slide fore-and-aft of the machine, a paper feed device carried by said carrier and moved thereby into and'out of contact with the platen or the paper thereon, a spring, and means whereby the position of the carrier on the bracket directs the effective force of the spring either to slide the carrier towards and cause the feed device to bear against the platen or to hold Ydi . the slide in its retracted position with the i''eed device out of Contact with the platen.

9. in a typewri'ting or like machine, the combination of Ya carriage,-a7platen carried thereby, a bracket carried by tl ecarriage andfhaving a slot therein, a paper feed device, a carrier therefor `mounted to slide on saidbraclet, an arm beneath the bracket extending` tliroughvsaid slot and adapted'in Vone position of the carrier to vbea-rV against the saniefin a direction at substantial right angles Yto tlie'direotion oi'` its sliding movement and inanotberposition of tbecarrerV to bear against 1t 1n the'dn'ection ot its sliding movement, and a-spring .connected to said arm.
