CHARLES F. BOWMAN, OF NEW HAVEN, CONNECTICUT.
CUTTING-NIPPERS.
IBPEOIFICATION forming part. of Letters Patent No. 355,373, dated January 4, 1887.
Application filed June 30, 1886. Serial No. 206,696. (No m0dcl.
T0 aZZ whom it may concern.-
Be it known that I, CHARLES F. BOWMAN, a citizen of the United States, residing at New Haven, in the county of New Haven, State of Connecticut, have invented. certain new and useful Improvements in Cutting-Nippers, of which the following is a specification, reference being had therein to the accompanying drawings, in which- Figure l is a View of a pair ofcutting-nippers with my improved detachable cuttingedges. Fig. 2 is an enlarged sectional view of i one of the jaws and of a cutting-edge, and
shows the screw holding the parts together.
My invention relates to that class of cuttingnippers which have detachable cutting-edges,
the object being improved means for holding the cutting-edges to the jaws.
The invention consists in making a recess in the jaw, the front side of which is undercut, and the back side of which is slightly inclined, and in making the cutting-edge to fit into the same, as is hereinafter more fully described.
To enable others to make and use my improved nippers, I will give a description of the same in detail.
The nippers A are of the usual form and construction, except the jaws. The jaws have transverse grooves or recesses B, the front side, a, of which is lower or shorter than the back side by the thickness of the part c of the cutting-edge, and is undercut or dovetailed. The back side, I), of the recess forms an angle with the bottom of the same greater than a right angle, so that as the cutting-edge is forced into the recess it is forced forward and into the undercut in the front part, a. The
cutting-edges have the parts 6 extending over and beyond the front side, a, of the recess and are made to fit into the recess B. In
order to make the cutting-edges sit firmly in the recess and be perfectly rigid, I make the parts in the recess a little longer than'the recess, so that the rear ends will not touch the bottom of the recess, as shownin Fig. 2. The cutting-edges are fastened to the jaws by screws.
The construction may be somewhat varied without departing from the spirit of my invention. For example, the under-cut may be in the cutting-edge and not in the jaw, and the jaw be made to correspond therewith.
Constructed as described, as the cuttingedges move in a circle the pressure of the edges against the wire to be cut will tend to raisethe part' 0 of the cutting-edge against the undercut in the front part, a, of the recess, and the rear part of the cuttingedge downward against the inclined back part of the recess, so that the greater the pressure on the cuttingedges the tighter they will be held in the jaws.
Having described my improved nippers, what I claim as new, and desire to secure by Letters Patent, is o A nipper-jaw, in combination with a detachable cutting'edge and a fastening device for holding them together, the jaw having a recess, the front side of which is lowest and undercut, the back side. of which forms an angle with the bottom of the recess greater than a right angle, the cutting-edge extending over and beyond the front side of the recess, and adapted to fit into it, as described.
. In testimony whereof I affix my signature in presence of two witnesses.
CHARLES F. BOWMAN.
