HENRY FLATER, OF FINDLAY, OHIO, ASSIGNOR OF ONE-HALF TO JOHN POE.

SAW-SET.

SPECIFICATION forming part of LettersPatent No. 269,402, dated December 19., 1882.

- Application filed August 23, 1882. (No model.)

To all whom it may concern Be it known that I, HENRY FLATER, a citizen of the United States of America, residing at- Findlay, Hancock county, State of Ohio, have invented certain new and useful Improvements in Saw-Sets, of which the following is a specification, reference being had therein to the accompanying drawings.

Figure 1 is a plan view. Fig. 2 is a side elevation. Fig. 3 is a longitudinal vertical sectional view, and Figs. 4 and 5 are vertical cross-sections.

This invention has relation to saw-sets; and it consists in the construction and novel arrangement of parts, as will be hereinafter fully described, and particularly pointed out in the claims appended.

The object of this invention is to give a uniform'set to any saw, from a fine handsaw to a large crosscut-saw.

Referring by letter to the accompanying drawings, a designates the base-plate, provided with the clamping-arm I), having the clamping-screw 0 near its middle portion and the perforated ears d at oneend, through which wood screws are to be passed to secure it to the bench, to hold it, in connection with the clam ping devices, securely in place on the bench. In plan view the base a is nearly in cross form, the edges of the transverse portion being recessed at e, and having the upper and lower inner i'acesff of this portion provided with vertical horizontal grooves g g, the inner walls of which are in line with the vertical walls of the recesses e, as shown in the drawings. A recess, 0, extends from each recess 6 to a recess, h, in each edge of the stem portion h of the base a, and vertical longitudinal grooves i i are formed in the inner facesjj ot' the projections k k, as shown. The stem portion h has a lateral slot, l, somewhat elongated, about the middle of its length, for the reception of a'lateral bolt, m, the purpose of which will be hereinafter explained. The base portion just described is preferably made of malleable iron, and is provided with a graduated scale, it, upon its face, at one side, as shown, and is recessed longitudinally in the middle of the transverse portion to receive an anvil, o, of steel, said anvil having a beveled front end, 0, which comes under the head of the pivoted jaw 11. The head 1) of this jaw is also of steel, and is pointed, and has an under bevel, q, as shown, to correspond with the bevel 0 of the anvil. A spring. 1", is let into a recess, 8, in the stem portion W, and has its upper end in engagement with the under-face ot' the pivoted jawp for the purpose of lifting thejaw after each blow upon its head.

tdesignates a sliding gage having arms t and 1?, which are provided on their upper and lower edges with vertical flanges u, which fit and work in the vertical groovesg g and it. The arms t t are provided on their outer faces, near or at their front ends, with vertical standards n, which carry on their rear edges guards v o of brass, against which the saw-teeth rest when being set. The arms t are perforated laterally at w for the reception of a bolt, m, which passes through them and through the elongated lateral slot Zin the stem portion h of the base a. This bolt m is provided with a thumb-nut, m, for locking the sliding gage in any position to which it may have been adjusted. The rear end of the sliding gage is provided with a verticallyadj ustable screw, 00, for elevating or lowering the back of crosscut-saws when they are being set, so that the desired angle may be given to the teeth of the same.

The operation of the device is very simple, and is as follows: The device is first securely fastened to the bench. The sliding gage is then adjusted by the scale to the grade of set desired. The points of the saw-teeth are then pressed against the brass guards and the head of thejaw driven down on each alternate sawtooth by a blow from a hammer or hatchet. The alternate teeth which have not been struck should be operated upon in a like manner from the other face of the saw. I

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a saw-set, the combination, with the base-plated, having the clamping-arm b, clamping-screw c, and perforated cars 01, of the anvil 0, having the bevel 0, and the pivoted jaw 19, having the head 0, with under bevel q, and the spring 7', substantially as and for the purpose specified.

2. In a saw-set, the base-plate a, recessed and grooved in its edges and having. the lateral slot in its stem portion h, the graduated scale, and pivoted spring-actuatedjaw, in comguards, and the vertical adjusting-screw a', re
