' the shelf, and at the same time to This invention relates to devices usually provided for engaging the side edges of the sheets as they are placedinto position for writing.

Heretofore the side age has been in the form of a ledge turned /up from the plate, .the latter provided witlf a claw or hook to fit tightly-upon the beaded upper edge of the paper shelf, as in the wellknown Underwood typewriting machine.

It has been found in practice thatzthese hooks and claws must be so tight, in order to hold the gage roperly upion the letterfeeding carriage, tffat it is di them along the paper shelf, owing to t eir strong binding actioni and moreover the shelf becomes scratched and marred.

The object of this invention is to provide for-convenient and easy attachment and detachment of the gage from the paper shelf and easy adjustment therealong, without any liability of marring the appearance of rovide a very effective means for holding t e gage in any position.

I According to this invention, a side gage plate is bentup at right angles from a base plate, which overlies the front face of the paper shelf. The upper end of the base plate is curved around the top of the headed edge. of the shelf, and 'may be provided with a bearing surface of felt or soft material, to prevent ma'rring the shelf. The curvedpor- ,tion of the plate is extended to form a fingerpiece. A second plate is hinged upon the main plate, and is also extended to form a companion finger-piece.

Projecting from the second plate is a pair of claws to catch between the edge of the beaded portion of the shelf and the rear face of the shelf. A spring gives the power to grip the shelf.

n the accompanying drawings, Figure 1 is a cross-section of the platen frame of an Underwood typewriting machine, showing how the improved gage is applied to the paper shelf. Fig. 2 is a view similar to Fig.

cult to ad'ust ii, but showing the improvedgage applied 1s a perspective to thejia er shelf.--Ei vi ,v shoy ingihe impl huiid gage in an invert position.

T usual platen 1 and axle 2 are revolubly'lnpunted 'in a'platen frame 3, which ineludes an inclined paper shelf 4, at the rear of'the platen, to support the paper during the operation of the mach-ine,t 1e shelf having its upper edge provided with a rolled or beaded rim 5. I v I u The side gage device comprises a plate 6, bent up from a bottom plate 7 which overlies the front face of the paper shelf 4, the plate 6,

serving to gage the edge of the paper as it is inserted between the shelf and. platen. The

upper end of the late 7 is curved as at 8,;to

- conform with the .eaded end 5 of the shelf 4,

and may be provided with a piece of felt or soft material 9; to prevent any marring of the surface of the shelf. v

Extendingdownwardly from the toppertion of the plate 7 are two ears 11, between V which extends a shaft 12. A plate. 1'4has a pair of ears 15, projecting upwardly, by means of which the plate is hinged upon the shaft 12. There are also projecting from theplate 14 two claws 16, which engage between the edge of the beaded portion 5 of the shelf 4 and the rear face of the shelf. It is preferred to separate these claws and form them so that they will have a binding or wedging action between the beaded edge and the shelf, to secure a substantial grip, to retain the gage against accidental skewing during the intermittent movement of the-typewriter caragainst the rear of the shelf to produce the wedging or binding action are designated as 16?, and'consist of cars bent up from the front edge of the plate 14. continued rearwardly to form a finger piece 17, and cooperates with a fingerpiece 10 extended from the curved portion 8 of the plate- 7, to form a grip. Springs 13, carried on the The plate 14 is shaft 12,-ongage the finger piece to cause the fingers 16 to ress against the shelf to hold the gage in p ace, as shown in Fig. 2.

To place the gage on the shelf, the finger pieces ,10 and 17 are pressed together as showIr/inFig. 1, to open the jaws of the clip, and the ga e is brought down on. the front faeeof the jielf 4, when the finger )icccs may bereleased and the springs 13 wili cause the rofki'ng of the gripping member 14 and cause the fingers 16 to wedge themselves between any time it is only necessary to press the fingenpi'eces 10 and 17, and wherever desired. held by aresilient justment of which there is no tendency to injure the front surface of the shelf.

Having thus described my invention, I claim:

A device of the character described, comprising a plate to be secured,- against the front face of a typewriter shelf and having a part to serve as a paper age, said plate exslide the gage The gage is very secure y gripping means, the'adtending over the upper er ge of the shelf and having a finger piece, hin ed claws for engaging at the rear of the shelfto hold the gage in place, a spring for forcing said claws into engagement with the shelf, and a companion ger piece carried by said claws. 2. A device of i the character described, comprising a plate to be secured against the front face of a typewriter shelf and having a part to serve as a paper age, said plate extending over the upper e ge of the shelf and having a finger piece, hin ed claws for engaging-at the rear of the shelfto hold the gage 1n place, a s'prin for forcing said claws into engagement wit the shelf, and a companion is Very convenient, and
