PAPER-GUIDE FOR TYPE-WRITERS.

'State of Illinois, have invented certain new" and useful Improvements in Paper-Guides for Typejtvrlters. of which the. following 1s a specitication.

This invention relates to adjustable paper guides for holding the paper firmly against the platen during the typewriting operation; and the object ot' tbe invention is to so constructI and mountthe guides that they may be individually adjusted to an)I suitable poi sition with respect toA thel platen, and so that ample space will be a'orded behind the rod on which the guides are mounted for erasures` and for theeasy manipulation of the paper.

Further objects will appear from a detailed description of the invention, which consists in the features of construction and combination of parts hereinafter described and claimed.

In the drawings- Figure 1 is a front elevation of a typewriter carriage and platen, showing the paper guides in their relation thereto; F ig. :2 a cross sectional view of the platen and carriage, showing one of the guides in elevation; Fig. 3 an enlarged sectional elevation of one of the guides; and Fig. 4 a sectional detail, taken on line, li--t of Fig. 3.

Referring to Fig. 1, the paper guides are carried upon a rod 5 which is provided -with a flat side 6, the ends of which rod are supported by forwardly projecting arms 7 formed on the end plates 8 of the carriage frame. The construction of the carriage and associated parts forms no part of the resent invention and need not be described 1n detail. The carriage frame serves to mount a platen 9 located diagonally to the rear and below the rod 5, space being afforded behind the rod to permit the operator to manipulate an eraser when it is desired to make erasures on the paper. Each of the paper guides comprises a flat plate l() provided, at its ends, with inturned ears 11 which are bored to receive the rod 5, and the plate l0 norm-illy extends diagonally toward the center or Lie platen and is provided, at. its lower end, with a curved `linger 12 adapted to press against the surface of the platen, the lower edge 13 of which is si'iglitly bent away from the platen to facilitate the initial Specification of Letters Patent. latenfpd F91), 22, 1910.

t )ositioning of the paper which is fed down l )elow thc platen and over a curved guide plate 14. the forward edge of which is closely l adjacent to and behind the curved lower edge of the nger 12, so that the papel' will slip easily from the guide plate behind the linger. Oneach side of the.ti ger 12, at its t point of connection with the plate 10, is a rearwardly extending tongue 15 which overlies the platen'and is curved in register' with the curvature of the linger. which line of curvature, as shown in F ig. 2, is of a slightlyr greater radius than that. of the surface of the platen, so that the paper will begnessed against the platen at a single point which is at or in 'proximity to the printing line.

i l i I Il@ plate 10, at its outer edge, is bent at right angles to afford an upper plate 1G which overlaps the upper edges of the ears 11 and is given a curvature commensurate with the curvature of said ears. The upper plate exof the ears and terminates in a handle 1T which extends diagonally upward from the rod 5 and permits manipulation of the guide as a whole. The plate 10 is provided, on its inner face, with a bow spring 1S which presses against the rod 5 and is adapted to normally abutagainst thc tintface (3 of the rod in such a manner as to hold the fingers of the guides under tension againstthe. surface of the paper.

In use, the guides can be adjusted to any placement by the pressure of the bow springs, which, however, are not of Sutlicient tension to prevent easy manual manipulation of the guides. When the paper is being initially inserted, the 'guides can be thrown out of contact with the platen by pressing on the handles 17, which pressure serves to lift the lingers 12 away from the platen, so that the paper can be easily inserted. Thereafter the guides can be snapped back into engaging position and held during the operation ofthe machine.

The construction of the guides is one which ermits them to be easil stamped or blocked) out of a plate of meta each of the guides being formed of a single piece of metal, with the exce tion of 'the s rings, so that the cost of tlie guides will extremely small and the expense of their assembling reduced to a minimum. The artends around substantially the upper halt` desired position along the rod and will be held against accidental longitudinal dis-V 2 asdieo rangement, furthermore, is one which is -extreniely effective in the addressing of envelops o1' other relatively thick paper, since the guides can be adjusted to leave only the necessary space between there for receiving the intended typewritin thereby holding the surface of the envelop firmly against the platen, which isfoften ditlieult in the addressing of envelops on typewriters of the usual character.

vWhat l regard as new and desire to secure bj: Letters Patent is:

l. ln a device of the class` described, in combination with a platen, a rod mounted adiacent to the pla ten the rod provided with a flattened face, a guide comprising upper and lower plates bent at an angle to one another. one of the plates beingrprovided, at. its edges, with inwardly tamed ears having holes through which the rod extends, the upper plate. terminating in an angularlj.' disposed handle, the lower plate terminating in a (leperl ig curved iin er, and a bow .s ring connected with one o the plates and adapted to bear against the rod, for holding the guide in adjusted position when said bow spring @intacts the flattened face of said rod, suiislantiaily as described.

:2. ln a device of the class described, in combination with a plaien, a rod mounted adjacent to the pieten the rod provided with a flattened face, a guide comprising upper and lower nietes bent at an angle to one another, one o the plates being provided, at its edges, with inwardly turned ears having holes through which the rod exlends, the upper plate terminating in an angolari); disposed handle, the lower plate terminating in a depending curved finger, the lower plaie being further provided on each side o the nger with upwardly extending tongues, and a bow spring interposed between one of the plates and the rod, 'for holdin# the guide in adjusted osition when said bow spring contacts the attened face of said rod, substantially as described. 3. ln a device of the class described, in combination with a platen, a rod mounted adjacent to the platen the rod provided with a flattened face, a guide comprising upper and lower plates bent at an angle to one another, one of the plates being provided, at its edges, with inwardly turned ears having holes througi which the rod extends, the upper plate having connected therewith a handle, the lower plate terminating in -a depending curved finger, and a bow spring connected with one of the pistes and adapted to bear against the rod for holding the guide in adjusted position when said bow spring contacts the flattened face of said rod, substantially as described. l

ei. In a device of the class described, in combination with a platen, a rod mounted adjacent. to the platen the rod provided with a flattened face, guide comprising upper and lower plates bent at an angle to one another, one o the plates being provided,-
