TYPE-WRITING MAClIINE.

Patented July 1, 1913.

Application filed March 26, 1912. Serial No. 686,239.

To all whom it may concern:

Be it known that I, GEORGE A. SEIB, citizen of the United States, and resident of Ilion,in the county of Herkimer and State of New York, have invented certain new and useful Improvements in Type-Writing Machines, of which the following is a speci fication. a

My invention rel atesto paper guiding and controlling devices for typewriting machines and its general object is to provide improved devices of the character specified.

More specificallyone object is to provide devices, preferably detachable,which guide,

5 restrain and control the paper beyond the printing line, preventing the paper from dropping downward so as to cover the printing pointand obstruct the type bars in their movements toward the platen.

Anotherobject is *to provide an improved erasing plate or shelf. Still another object is to provide guiding devices for the written portion of the paper, said devices extending beyond the platen and providing a passage-way, one side of which is temporarily removable completely: to expose the paper above the printing line for the purpose among others of enabling erasures and corrections to be made with facility.

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

In the accompanying drawings whichshow my invention in the form of an attachment applied to the carriage of a machine like the N o. 11 Remington typewriter, Figure 1,is a fragmentary top plan view of the platen and carriage'showing my invention applied thereto, parts of the machine being omitted. Fig. 2 is a side elevation of the parts shown-in Fig. 1. Fig. 3 is a fragmentary side elevation of a modification. Fig. 4 is a fragmentary perspective view of the preferred form of mounting.

Referring to Figs. 1 and 2, the platen 1 has an aide 2 and is shiftably supported on a carriage truck comprising front and rear bars 3 ands and connecting endbars 5. The platen is shiftable up and downonthe truck by mechanism of known construction not shown herein. a The types. cooperate with the front face of the platen.- The paper 6 is guided and fed paper and printlng line, the feed roll ers 7 and 8 cooperating with the lower side of the platen. r

The devices embodying my invention in the present instance are detachably supported on the carriage andcomprise angular supporting arms 11 which are detachably secured to theends of the usualscale bar '12 on the front bar 3 of the carriage truck by screws 13. The lower of the arms 11 are cut away as indicated at 14 providing feet 15 which rests on the front bar 3. These feet are preferably made a little longer than needed in. order that they may be filed down different extents to compensate for variations in the distance between the upper face of the bar 3 and the screw holes for the screws 13. The construction is such that when the screws 13 are tightened the arms 11 are secured rigidly in place, the feet 15 cooperating with the bar 3 to preventpivotal movement of the arms around the screws 13 as axes. The arms 11 are parallel with each other and extend introduced at the rear of the platen and is around the lower and forward sides of the same by devices compris-v pressure forward end portions horizontally rearward from the front b'ar3 until close to the platen where they are bent or inclined upward, the inclined port-ions .or extensions ll terminating at points considerably above the platen and slightly to the rear thereof. As will be seen from Fig.

1 the arms 11 are spaced apart to such an extent that they are near the ends of the platen. The arms 11 provide -a detachable support for an erasing device or shelf which comprises a plate-like body portion 16,

bar 17 around which the upper end portion of the plate 16 is bent or hooked, the two parts being suitably secured togetl1er,as by soldering. The ends of as indicated at 18, and these coned ends loosely into bearing holes 19 in the rear ends of the extensions 11. The erasing shelf is thus pivotally supported oii'the arms 11' and preferablv of thin sheet metal, and a rod or E the rod 17 are concd, I fit inclines downward and forward from \he 1'od'17, the lower forward edge of the plate l6 resting against the face of the platen which supports it in proper working poststion. The erasing plate is conveniently arij stood that when the device 20 a sheet, in maintaining or notches 24 in the inner ranged so that the paper may be advanced from theprinting line and pressed bacl r, against the plate 16 which provides a suitablesupport against which erasures may be made. I 1

Heretofore operators have experienced trouble, especially when nearing the end of the written portion of the sheet above the printing line and out of the path of the type bars. Where the paper is not particularly stiff and especially where there isa current of air inv the room due either to a natural breeze or a fan or the like, the part of the paper above. the platen and out of the control of the paper feeding and guiding devices frequently drops or is blown downward and forward .so as 'to cover the printing line. In order to overcome this I provide novel means for mounting a guide that restrains that portion of the paper which extends beyond the platen, in such a way as to prevent it from dropping or 'being blown forward, the result being that with my devicethe advanced portion of the paper is always maintained above the platen] In the present instance the device comprises a wire retainer or bail 20 which is bent or zig-zagged, as illustrated in Fig. 1,. and has lateral side portions 21 which ter-' minate in outwardly bent bearing ends 22 that engage in hearing holes 23 formed in the arms 11 about at the junction of the body of the arms and the extensions 11. The si portions 21 are seated in grooves faces ofthe extensions 11, the notches inclining-upward and rearward from the holes 23 so that they normally maintain the retaining device 20 inclined rearward from itssupport, 'as shown in Fig. 2. The paper 6, after leaving the control of the platen andthe pressure rolls 10, passes upward behind'the device 20, which cooperates with the frontface or surface of the paper throughout its width and directs it upward and rearward, restraining and overcoming any-tendency to drop downward and forward. The forward faces of the notches 24 are curved or flared slightly near their upper ends so as to give an easy start in pulling the device 20 forward to abnormal position. This movement of the device 20 to abnormal position is for the purpose of freeing the upper part of the paper so that'erasures may conveniently be made against the plate 16 or for any other desired purpose. It will be underis grasped and pulled forward the spring of the wire of which it is composed will enable the side portions 21 to be forced or cammed out of the depressions or notches 24: so that the device 20 may be swung forward pivotally until it is arrested by the scale bar 12 when it will be in the dotted line position shown swung forward in 2. The device 20 will be retained inabnormalfposition by the friction between the side portions 21 and the inner faces ofthe-bars 11'. is loosely pivoted swung upward. so

sinceithe erasing plate it may lee conveniently that if desired the underlying sheets of a manifold pack may he (11- rected beneath it, enabling erasures to'be made onthe overlying sheet or sheets directly against-the erasing plate as a backing. On swinging the device 20 back to normal position the side portions 21 will spring outward'as soon as they register with their respective notches 24 and will cooperate frictionally with the notches to retain the device in its working position. Said device 20 may also be lowered or swung down to abnormal position when the machine is,

not in use.

The paper retaining or'directing device 20is located so that its lower portion 1s forward of and slightly above the pointat which the paper leaves the control ofthe platen and the uppermost feeding devices that cooperate with the platen, namely, the pressure rolls 10. The arrangement is such that the paper, the platen, control of or handling on the part of the operator, and cannot by any chance escape forward under said device. Further it is to .be noted that the supports 11 and the devices mounted thereonare arranged on the non-shiftable carriage truck but that the lower end of the looselypivoted erasing shelf 16 rests against the shiftable platen. Consequently cated by dotted lines in Fig. 2, the supports 11 and the device 20 will not-be affected;

but the erasing plate will swing outward and forward on its axis which remains stationary, to the dottedline positionin Fig. 2. The erasing plate .16 and the bail or frame QTAare substantially parallel and provide in effect a passage-way extending above and beyond the platen, whichpassage-way automatically receives the paper after it has left the control guiding devices which cooperate with the platen, and thereafter guides the paper after leaving the control of passes automatically into the the device 20 without any care whenthe platen is shifted upward as indiof the'various feeding and throughout its entire width; that this passage-way inclines upward and rearward from the upper, forward side of the platen that its rear side is composed in the present?- instance of a loosely pivoted erasing plate or shelf; and that its forward side-consists of a movable paper guide which may be out of the way and also to render the paper accessible for any desired purpose.

Both the erasing late device and the paper. retaining dev 'oe or and downward so asto get it bail are quite. light so that they do not add appreciablyto the weight of the carriage. By making the 13:: W

, one of which is provided retaining device in' the form of a wireframe having a bent or zig-zag main portion'as;

illustrated, it acts in efiectpas would a con- 'tinuous plate of a width equal to the vertical distance between the upper and lower bends of the wire frame. I

' Modifications may be resorted to within the scope ofmy present invention and parts of it may be used without other parts. For example, Fig. 3 illustrates a paper retaining device which is not associated with any In the Fig. 3 construction erasing plate.

the detachable supporting arms 'Wl1i0l1 correspond to the arms 11 of the first con-- struction, terminate in short extensions 25*, with an inwardly projecting stop pin 26 against which the pivoted retaining device 27 is adapted to rest normally, the stop pin taking tlieplace of the notches 24' of the prior construction and serving to maintain the retaining device 27 in normal position.

' What I claim as new and desire tests matically at 'its front cure by Letters-Patent, is

1. In a typewritingmachine, the combination of a carriage comprisingta front bar, a platen, supporting arms 'detachably secured to and-extending rearward from said front bar, and a restraining device pivotally supported on saidarms, the paper after it passes above the platenface'.with the rear side of said device.

2. In a typewriting machine, the combination-of a carriage comprising a front' bar, a platen on sa d carriage, horizontally arranged supporting arms having feet 00- '7 operating with the'upper'face of said front bar, said arms being detachably secured on said front' bar,

' inclined position above the platen where it cotiperates automatically with the frontface of the paper after it leaves the platen and prevents the paperfrom dropping forward.
