To all whom it may concern:

Be it known that I, J. (J.

the pressure-head or cross-bar connected to the outer end of the frame, all as hereinafter set forth.

In the accompanying drawings, the letter A designates the main frame, consisting, prefferably, of two bars, B B, bent at one end to form the fork O of the frame, and at the other j to provide a slot or opening, D.

To the outer end of the frameA is attached the pressure-head or bar E, which is usually pivoted to permit the frame to he turned while the bar E is pressed against the body of the operator.

P indicates the crank whereby the lever is This crank is preferably made with two handles, Z Z, so that it can be worked with both hands. The bearing end o of the crank is provided with an anti-friction roller, 8, which works in the slot G of the lever.

The fork of the frame is provided with pointed projections V, which extend beyond the cutting-edgeof the knife and serve to hold the instrument firmly in position when pressed into the rick. A transverse guide-bar, I, supports the lever near the middle of the knife.
