JOHN H. VELLS, OF NEV YORK, N. Y.
KNlFE FOR CUTTER-HEADS..
SPECIFICATION forming part of Letters PatentNo. 339,606, dated April 6, 1886.
(No model.)
To all whom it may' concern:
Be it known that I, J oHN H. WnLLs, of the city and State of New York, have invented a new and useful Improvement in rood-Working Tools for use in Machine Cutter-Heads, of which the following is a specification.
The object of my invention is to provide a plow or analogous woodworking tool in such manner as to cause it to make a clean square cut when straight downward cuts are desired, and when applied to a cutter employed on a cutterlhead will avoid heating and discoloration of the wood by friction.
My invention consists in providing such plows or cutters with a narrow rib on the face in line with the part of the tool at which the straight downward out is desired.
It also consists in a cutter having the workingface side wider than the other, and having suc-h face provided with the rib at the point of straight out, as before stated.'
It also consists in a cutter inclined inward slightly from the cutting-edge toward the body of the tool.
In the drawings which accompany and forni part of this specification I have shown a cut ter designed for use with an ordinary cutter head for cutting a straight even groove.
Figure lis a plan view showing a completed 'cutter with the face of the tool on opposite at the different ends. Fig. 2 is a perspective of such a tool before the bevel is given it, or before grinding. Fig. 3 is a longitudinal section of the completed cutter.
A in the drawings designates the cutter. a are ribs projecting slightly from the straight face of the tool. These ribs or'ridges are made in any suitable way in making the tool, and when it is beveled and ground form short projecting spurs from the edge at the point of its straight downward out. The rib is made prefsides of the cutter erably with its inner side inclining, to forma sharp angle with its outside edge; but in some eases it may beV of a rectangular form. The entire edge of the cutter-blade is slightly beveled from its straight or face side backward, as shown in the drawings at b, to prevent any thing but the cutting-edge comi ng in contact or rubbing the sides of straight cut of the moldv ing or other device operated upon. This cutter may also, when desired, be slightly inclined in the direction of its length from the cutting-edge toward the body of the tool, to assist in making it freely clear the wood without touching or rubbing it. This narrowing in practice is very slight, and, when not enough to be perceptible to the eye, will effect a marked result in the working of the tool in actual operation. The rib being upon the straight side of the tool, the grinding upon the bevel sharpens the rib, as well as the rest of the cutting-edge. Such cutting-tools when in use are always set at a less incline than the bevel on the ends of the same, and the ribs therefore precede the main cuttingedge, and the tool will therefore make a clean and straight out. The bevels of the tool prevent blaeking or discoloration by rubbing against the edge of the straight out of the wood.
I claim- A reversible woodworking plow-cutter provided on its workingfaces with ribs located at its sides, to form projecting ,spurs in advance of the cuttingedges, and having its sides tapering slightly to the rear thereof, whereby in grinding the cutting-edges of the tool the spurs will present the saine relative degree of projection beyond the line of such cuttingedges, substantially as and for the purpose set forth. l
In testimony whereof I affix my signature in presence of two witnesses.
JOHN H. WELLS.
