SHEARS.

Application filed July 30, 1917; Serial No. 183,547.

To all whom it may concern:

Be it known that we, THOMAS J. FEGLEY and GEORGE O. LEOPOLD, citizens of the United States, and residents of Philadelphia, county of Philadelphia, State of Pennsylvania, have invented certain Improvements in Shears, of which the following is a specification.

Our invention relates to certain improvements in shears for cutting comparatively heavy articles and articles diflicult to cut under ordinary conditions.

One object of our invention is to design the shear so that it will be compact and can be readily manufactured by hand and which will make a shear out.

A further object of the invention is to design the shear so that the lever will be a simple lever and the shear cut will depend upon the peculiar shape of the blade and the location of the pivot in relation to the bed.

In the accompanying drawing:

Figure 1 is a perspective view of our improved shear;

Fig. 2 is a side view showing the shear blade in an elevated position;

Fig, 3 is a similarview showing the blade partially depressed; and

Fig. 4: is a sectional view on the line 44, Fig. 3.

Referring to the drawing, 1 is the base of the shears having projections 2 at each end by which it can be secured to a' bench. 3 is a curved extension carrying the bar 4 for the pivot 5 of the lever 6. This lever has a handle 7 and a body portion 8 to which the blade 9 is secured by screws 10, or other fastenings. 11 is a bed plate secured to the base by screws 12, and this bed plate has a flange 13 against which the material to be cut is held. The edge 14:

of the plate forms one blade of a shear 1n connection with the edge 15 of the blade 9. The bedplate 14 extends laterally beyond the base, as shown in Fig. 4, so that the knife will be clear of the base when the cut is made.

The invention is particularly adapted for cutting brake linings, and like materials, which are woven and usually consist of a fiber and metal woven or braided together, and where it is desirable to make a clean cut. A tool of this character can be readily mounted on a work bench and the ma terial, which is usually in long lengths, can be cut to any short length desired, The cut will be sharp so that when the ends are brought together they will fit snugly.

While the invention is particularly adapted for cutting brake linings, &c., it can be used for cutting other materials without departing from the essential features of the invention.

We claim:

The combination in shears, of a base; an overhanging bearing cast integral with the base; a bed plate mounted on the upper surface of the base and having an upwardly projecting flange at its inner edge; screws for securing the bed plate to the base; a lever pivoted to the bearing and having an integral handle and body portion, the body portion extending on the same side of the pivot as the handle; and a blade attached to the side of the body portion, the body portion being recessed to receive the blade, the blade having a curved cutting edge so shaped that when the lever is drawn down the blade will have a shearing movement past the edge of the base plate.

In witness whereof we affix our signatures.

THOMAS J. FEGLEY. GEORGE O. LEOPOLD.
