-HOOP-.PLANER KNIFE.
1 SPECIFICATION forming part of Letters Patent No. 355,580, dated January 4, 1887.
Application filed September 28, 1885. Serial No.178,470. (No model.) i
To all whom zit may concern:
Be it known that I, ELIJAH -WINDsoR, a British subject, residing at Oil City, in the county of Lambton, in the Province of Ontario, Dominion of Canada, have invented new and useful Improvements in Hoop-Planer Knives, of which the following is a specification.
My invention generally relates to that class of knives that are used in rotary heads for planing hoops or similar articles, and particular] y relates to that class of knives that plane the principal surface of the object, and at the same time shape the corners orfedges.
My invention therefore consists of constructions and combinations, all as will hereinafter lie described in the specification, and pointed out in the claims, reference being had to the accompanying drawings, in which Figure 1 represents a front elevation of a planer-knife embodying my invention; Fig. 2, a rear elevation of the knife shown in Fig. 1;
Fig. 3, a longitudinal section, and Fig. 4 a
transverse section on line :0 x.
A represents the body of the knife, having the curved edge a and lips a. The outer edges, a", of the front side of the knife are'beveled at a from the lips a to about half-way the length'of the knife. This-beveling gives contact with the material to be planed.
The back of the knife is provided with the depression or recess a, which 1 reduces the thickness of the blade at that point, and consequently the time and labor required to regrind the knife.
I am aware that'bits have been provided with cutting-edges at both ends and grooves on the front and back, so that the bit may be reversed and used either for cutting a tenon or groove, and that the cutting-edges of knives have been grooved to lighten the same, and these I do not claim; but a What I do claim is 1. A hoop-planer knife having the cutting edge a, the lips 64, and the bevelededges a on the front of the knife, and extending to about midway of the length of the latter, substantially as described.
2. A hoop-planer knife having the cuttingedge a, the lips to, the beveled edges a on the front of the knife, and the recess 64* on the back of the knife, substantially as described.
