WILLIAM B. RISDON, OF TRENTON, NEW JERSEY, ASSIGNOR TO THE AMERICAN SAW COMPANY, OF NEW YORK, N. Y.
INSERTIBVLE SAW-TOOTH.
SPECIFICATION forming part of Letters PatentNo. 289,715, dated December 4, 1883.
Application filed August 23, 1883. (N0 model.)
.To aZZ whom it may concern.-
Be it known that I, WILLIAM B. BIsnoN, of Trenton, in the county of Mercer and State of New Jersey, have invented certain new and useful Improvements in Inserted Saw-Teeth, of which the following is a full, clear, and exact description.
Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in both the figures.
Figure 1 is a side elevation of a part of a saw-plate to which my improvement has been applied. Fig. 2 is a sectional elevation of a part of the same, taken through the line 00 m, Fig. 1.
The object of this invention is to secure inserted teeth in the plates of circular and other 'saws without straining the said plates.
The invention consists in a saw-tooth made with a shoulder, a toe, a perforation, and a slit at its heel, to adapt it to be secured in a recess in a saw-plate provided with a shoulder and a recess at the rear end of the said toothreceiving recess by a rivet wholly within the said tooth, as will be hereinafter fully described.
A represents a sawplate, in the edge of which, and at suitable distances apart, are formed semicircular recesses B, to receive the teeth 0. The concave edge of the plate A, around each recess B, is beveled into V-shape, and the convex edge of the tooth O has a V- shaped groove formed in it to fit uponbeveled edge of the plate A.
Upon the heel of the tooth C is formed a shoulder, D, to abut against a corresponding shoulder, E, formed upon the plate A at the inner end'of the concaved edge of its recess B, to support the tooth against the pressure caused by the resistance of the substance being sawed.
In the edge of the saw-plate A, at the shoulder E, is formed a small recess, F, and upon the heel of the tooth 0, beyond the shoulder D, is formed a toe, G, as shown in Fig. 1.
In the heel of the tooth 0, near the shoulder D and toe G, is formed a small circular perforation, H, from which a slit, I, leads out to the concave edge of the said tooth (3, so that when the tooth has been inserted in its seat the driving of a rivet, J, into the perforation H will force the toe G into the recess F, and thus fasten the tooth C in its seat. The rivet J is then headed down enough to keep it in place.
WVhen the tooth G is to be detached ,the rivet J is driven out with a punch or other suitable means, and the tooth can then be turned out.
With this construction the rivet, being wholly within the tooth, puts no strain upon the saw-plate, and consequently does not atfect the trueness of the said plate, which is not the case when the tooth is fastened in place by a rivet driven through a hole formed partly in the tooth and partly in the plate. 7
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is
l.' The combination, with the saw-plate A, having recess B, shoulder E, and recess F, and the tooth 0, having shoulder D, toe G, perforation H, and slit I, of the rivet J, substantially as herein shown and described,whereby the tooth is secured in its seat without putting any strain upon the saw-plate, as set forth.
2. A separate saw-tooth, 0, made, substantially as herein shown and described, with a shoulder, D, a toe, G, a perforation, H, anda slot, I, at its heel to adapt the tooth to be secured to its seat ina saw-plate by a rivet wholly within the said tooth, as set forth.
3. A saw-plate made, substantially as herein shown and described, with a semicircular recess, B, to receive the tooth, ashoulder, E, at the inner end of the concaved edge of said recess, to receive the thrust of the tooth, and a recess, F, in the edge of the saw-plate above the shoulder E,to receive a toe of the tooth, as set forth.
WILLIAM B. RISDON. WVitnesses:
JAMES T. GRAHAM, EDGAR TATE.
