SAW-SET.

SPECIFICATION forming part of Letters Patent No. 772,295, dated October 11, 1904.

Application filed February 1, 1904. Serial No. 191,520- (No model.) i

T0 at whom, it may concern:

Be it known that I, HENRY RICE, a citizen of the United States of America, residing at Crawfordsville, in the county of Montgomery and State of Indiana, have invented certain new and useful Improvements in Saw-Sets, of which the following is such a full, clear, and exact description as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, forming a part hereof.

The object of this invention is to produce a saw-set of a simple construction by the use of which any desired set can be given to the sawteeth rapidly and efficiently. This object is attained in the construction illustrated in the accompanying drawings, and hereinafter fully described. A

The invention consists in certain novel features particularly pointed out in the claims.

In the annexed drawings, Figure 1 is a plan view of my improved saw-set, a portion of a saw-blade being indicated in dotted lines. Fig. 2 is a side view with a portion broken away, and Fig. 3 is an end view of the same.

In carrying out my invention I employ a U-shaped frame A, having longitudinal slots B in its sides and having a set-screw C swiveled in its shoulder or base. The ends of this frame are bent outward to form guard-flanges or stops D, against which the edge of the sawteeth rest when the tool is in use. These stops are greater in height than the sides of the frame, so that a saw-blade resting upon the sides of the frame will abut against the stops, as shown in Figs. 1 and 2. Between the side bars of the frame is fitted an anvil-bar E, one end of which is engaged by the set-screw C, whereby when the said screw is rotated the said bar will be adjusted longitudinally in the frame. Bolts F, fitted in the anvil-bar, project through the slots B in the frame and are adapted to secure the said bar firmly in the position to which it may be adjusted. The free end of the anvil-bar projects from the open end of the frame between the flanges or stos and is beveled on its upper face, as shown at In practice the saw-blade is placed over the anvil-bar and U-shaped frame with its teeth abuttingagainst the stops, as clearly shown, and the set-screw at the base of the retainingframe is then manipulated to adjust the anvilbar and bring the beveled portion of the same more or less under the saw-tooth, according to the set to be given the same, as will be readily understood. When the proper adjustment of the anvil-bar has been obtained, the bolts F are tightened, so as to hold the parts firmly in that position. The operator then holds the saw down on the tool with one hand and with a small hammer in the other hand strikes. the saw-tooth a sharp blow, so as to bend it down to the beveled face of the anvil-bar. The sawblade is then moved along, so as to bring the next alternate tooth into position to be set. After half the teeth have been thus set in one direction the saw is turned over and the remaining teeth are set in the opposite direction.

The stops or flanges against which the saw blade rests may be straight, as shown, or they may be curved in order to accommodate circular saws. These stops prevent the saw shifting its position and causing one tooth to project farther than the others over the anvilbar, the result being that a uniform set is given all the teeth.

It will be noted on reference to Fig. 2 that the sides of the adjustable frame are of the same height as the anvil-bar, so that the said frame aids in supporting the saw-blade. It will also be noted that the upper edges of said sides adjacent to the stops are cut away on a line corresponding to the bevel on the end of the anvil-bar, so that there will be no projections above the beveled surface of the anvil-bar, and consequently there will be no tendency to buckle or warp the tooth or notch the edge of the same when it is struck by the hammer or other setting-tool.

The device is extremely simple, and its advantages are thought to be obvious.

Having thus described my invention, what I claim, and desire to secure by Letters Patcut, is-

1. A saw-set comprising an anvil-bar hav ing a beveled end, and a frame connected to the anvil-bar and having its ends extended cured to the anvil-bar and having its ends extended laterally to form stops, the beveled portion of the anvil-bar being between said stops and the sides of the frame having their upper edges inclined adjacent to the stops to correspond With the bevel of the anvil-bar.

In testimony whereof I have signed this specification in the presence of tWo subscribing Witnesses.

HENRY RICE.
