FEED GUIDE FOR PRINTING PRESSES.

. Application filed June 15,

T 0 aZZ whom it may concern;

Be it known that I, CLYDE L. VVELsI-I, a citizen of the United States, residing at Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Feed Guides for Printing Presses, of which the following is a specification.

This invention relates to feed guides for printing presses to facilitate the positioning of the paper upon the platen prior to the printing operation. I

Objects of the invention are to provide a device of the character described, in a man; ner as hereinafter setforth, which is simple in its construction and arrangement, strong, durable and efficient in its use, readily positioned, which permits of printing closely thereto, and which is comparatively inexpensive to manufacture.

To the accomplishment of these and such other objects as may hereinafter appear, the invention consists of the novel construction, combination and arrangement of parts herein specifically described, and illustrated in the accompanying drawing wherein is shown an embodiment of the invention, but it is to be understood that changes, variations and modifications may be resorted to which come within the scope of the claims hereunto appended.

In the drawing forming a portion of this specification and wherein like numerals of reference designate corresponding parts throughout the several views:

Figure 1 is a top plan view of a plurality of feed guides attached to a draw sheet.

Figures 2 and 3 are enlarged top and bottom plan views, respectively, of the guides, in accordance with this invention.

Figure "if: is a sectional view on line IV- IV, Figure 2.

Figure 5 is a rear elevation of the device.

Figures 6 and 7 are enlarged detail perspective views of the wedge member and the gauge member, respectively.

Figure 8 is a top view of the tongue member.

Referring in detail to the drawing 1 denotes the body portion preferably constructed from sheet metal and rectangular in contour. The bottom portion 2 thereof is formed to provide a pair of forwardly projecting pointed prongs 3. The ends of the body portion 1 are open, and the top of each Specification of 'Iietters Patent.

of the side members {10f the body portion is provided with a longitudinally extending flange 5 having enlarged rear and forward ends 6. r

, A gauge member 7, provided with an angularly disposed depending head 8, is pivotally connected in the rear lower end of the body portion 1 by means of the shaft- 9, which passes through the apertures 10 in the side members 4 and through the apertured ears 11 of the gauge member 7. The head 8 is formed integral with the forward end of the gauge member 7 and has its lower edge provided with notches 12, which latter "are adapted to overlap the points of the prongs 3. The rear end of the gauge member 7 has an upwardly disposed arm 13 formed integrally therewith.

Slidably mounted in the body portion 1, on top of the gauge member 7, is a wedge member 15 provided, at each side thereof, with a forwardly tapering side member 16. The rear end of the wedge member 15 is formed with a vertically extending portion 17 having a rearwardly disposed lug 18 punched therefrom.

The gauge member 7 and the head 8 thereof, at the point of juncture, are formed with a slot 19 for the insertion of a resilient tongue member 20'; adapted to extend through and project from the body portion 1, beneath the gauge member 7.

In practice the operation of the feed guides is as follows: By sliding the wedge member 15 rearwardly the lug 18 thereof will strike the arm 13 of the gauge member 7, thereby lifting the head 8 clear of the prongs 3. The device is attached to the draw sheet positioned on the platen of the printing press, by inserting the prongs 3 into and beneath the draw sheet and then sliding the wedge member 15 forwardly thereby forcing the head8 upon the prongs 3 beneath the draw sheet. The action of the notches 12 upon the prongs 3 will serve to augment the gripping action therebetween. The flanges 5 of the body portion 1 engage the wedge member 15, when the latter is slid in the forward direction to secure the device upon the draw sheet. The vertical portion 17, of the wedge member 15, extending above the body portion 1, facilitates the manipulation of the wedge member 15. The enlarged rear and. forward ends 6, of the flanges 5, retains the wedge member 15 in the assembled position, as the vertical portion 17 thereof is of greater width than the Spare bet-ween either of the ends 6.

The device may be used either with or without the tongue member 20. It is employed to "facilitate to positioning the sheet to be printed upon the draw sheet, but would not be used when printing closely to the guide. The tongue 20, being resilient, may be frietionally drawn and held in the body portion 1 in any position desired.

W hat I claim is? l. A feed guide for the purpose comprising a body portion provided with prongs, a gauge member pivotaily connected in the said body portion, and a wedge member slidably mounted in the body portion for forcing said gauge member against the said prongs.

i feed guide for the purpose set forth comply sing a body portion provided with a pair o'fforwardly disposed prongs, a gauge member pivotally connected in the said body portion and including a depending head,,

and a wedge member slidably mounted in the body portion for looking said head against said prongs.

8. A- feed guide for the purpose set forth comprising a body portion provided with a pair of prongs, a gauge member pivotally connected in said body portion and including a depending head, said head formed with a pair of notches adapted to overlap said prongs, and a wedge member slidably mounted in the body portion for holding CLYDE L.
