WILLIAM P. HARMONY, OF SIDNEY, OHIO.

FEED-GUIDE FOR PRINTING-PRESSES.

Application filed September 11, 1912.

T 0 all whom it may concern Be it known that I, WILLIAM F. HAR- MONY, a resident of Sidney, in the county of Shelby and State of Ohio, have invented certain new and useful Improvements in Feed-Guides for Printing-Presses; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to use the same.

This invention relates to feed guides for platen printing presses, that is, to guides or gages of the character secured to the tympans of such presses to insure correct positioning and the holding of sheets as they are fed to the press.

The object of the invention is to provide such a guide of great simplicity, effectiveness, and without movable parts or parts liable to be bent or broken.

The invention consists in the construction hereinafter described and particularly pointed out in the claims.

In the accompanying drawing which illustrates the invention and forms part of the specification ;Figure 1 is an enlarged side elevation of the guide secured to a tympan, the latter being shown in section; Fig. 2 is a plan view of the same; Fig. 3 is a plan view of a blank such as used for making the guide. 7

In making the improved guide I employ a plain straight blank 1 of brass, copper, or other suitable material, preferably cutting it from a longer strip, or a sheet, and bending the blank into final shape at a single operation. In Fig. 3 the three transverse broken lines denote the location of the required bends.

The guide, which is complete in itself, comprises a main flat part 2, which in use is connected to a press tympan by any suitable adhesive material, a part 3 extending up ward and a little forward, a reversely bent part 4, and a front foot 5 in, or nearly in, the plane of part 2. The parts 3 and 4t brace each other and are not liable to be accidentally bent out of position. The corners Specification of Letters Patent.

of the blank are shown clipped; this is not essential but is preferred, especially at the front end since it assists in placing the guide on a tympan as hereinafter described.

Numeral 6 denotes a tympan such as suitable for use in a press of the character stated. The top or draw sheet 9 of the tympan where a guide is to be located has accurately cut therein a slit 7 a little longer than the width of the guide, and into this slit the foot 5 is entered until the part 4 reaches the front edge of the slit which exactly locates the guide and that without requiring either skill or judgment on the part of the workman. The slit 7 being cut by a sharp instrument, and the foot 5 entering easily therein, no ragged edges or parts, such as might interfere with movement of the sheet fed, are formed, as in some cases in which guides are formed with projections which themselves puncture the tympan. The foot 5 extends entirely across the guide and therefore when it is entered in the slit 7 it protects the whole width of the guide against the fed paper working under the guide so as to permit a crooked feed. The upwardly projecting part of the guide, which inclines toward the operator, guides the fed sheet downward and with the small overhanging loop 8 tend to keep it from curling up and slipping over the guide.

This simple device has no movable or adjustable parts, and no pins, screws, or the like, to get out of adjustment, break or be lost.

The invention is not limited to the exact form shown. For example, although it is preferred to have the edges of the blank and of the guide parallel this is not essential. Sfor is it essential that the parts 3 and 4 be parallel, nor that part 3 incline forward.

Having thus described the invention what I claim and desire to secure by Letters Patent of the United States is 1. A guide for fed sheets in platen printing presses comprising a continuous strip of metal having a main fiat body portion, a double upward and forwardly inclined extension, and a front foot in substantially the the plane thereof in advance of the lower plane of the body portion and extending end of said upward extensionbelow the clear across the guide. bearing portion for said fed sheets.

2. A guide for fed sheets comprising a In testimony whereof, I have signed this 5 single strip having a supporting body porspecification in the presence of tWo subscrib- 15 tion, an upward extension against which ing Witnesses.
