SPRINGBLOCK SET FOR SAWS.

messes.

Specification of Letters Patent.

Patented Mar. 3,1914.

To all whom it may concern Be it known that I, Ensnnn GODIN, a sub jcct of the King of England, residin at I-Iarrisville, in the State of New Y ork, United States of America, have invented certain new and useful Improvements in Spring-Block Sets for Saws, of which the following is the specification.

This invention relates to improvements in spring block sets for saws and the objects of the invention are to provide a portable device which may be readily used to accurately set saws and in which the degree of setting may be adjusted by simple means.

Further objects are to construct the device of few and workable parts not likely to come out of order and which may be readily used by unskilled workmen and it consists essentially of the improved construction hereinafter described in detail in the accompanying specification and drawings.

I11 the drawings, Figure 1 is a perspective view of the device. Fig. 2 is a longitudinal section of the same in position. Fig. 3 is an end elevation. Fig. 1 is a transverse section through the clamping bolt.

In the drawings like characters of reference indicate corresponding parts in all the figures.

Referring to the drawings, A represents the anvil member on which the teeth of the saw are adapted to be shaped, to which end it is formed with an inclined portion 10 on which the teeth are adapted to be bent to the proper inclination.

B represents a longitudinally adjustable gage member in the form of a plate, fitting within a dovetail slot 11 on the anvil member and adapted to be held in adjusted position by suitable clamping means. The clamping means which I have devised comprise a threaded pin 12 in the side of the gage member extending through a slot 13 in the wall of the dovetail groove, said pin having a clamping thumb nut 14 thereon adapted to force a plate 15 against the side of the anvil member. For further security the side of the anvil member may be formed with teeth 16 adapted to receive a single tooth 17 on the plate 15.

C represents a hammer member reciprocable to and from the surface of the anvil member, and supported by a plate spring 18 which is secured at 19 to the gage member. The spring is adapted normally to maintain the hammer member in slightly raised position. The upward movement of the hammer member is adapted to be limited by suitable means, such as downwardly projecting plates 20, secured to the sides of the spring member and having enlarged ends 21. adapted to fit within dovetail slots 22 in the sides of the gage member B. The underside of the hammer member is shaped to conform with the inclined surface 10 so that it will shape the teeth of the saw thereto. It will be observed that the dovetail slot 11 is formed by flanges 2 1 and 25 which project upwardly from the surface of the anvil member.

For convenience in attaching the anvil member to the top of a stump or other form of support on which it is placed, it may be provided on the under-side with a plurality of spikes 23.

The device may be used to set ordinary cross-cut saws as well as circular saws. In using the device the anvil member is secured to a suitable support and the saw placed across the same in a substantially horizontal position, each particular tooth being brought beneath the hammer member and the hammer member is then driven down on the tooth by means of a suitable sledge or mallet. The inclination may be regulated by adjusting the supporting member longitudinally by the means previously described.

As many changes could be made in the above construction and many apparently widely different embodiments of my invention, within the scope of the claims, constructed without departing from the spirit or scope thereof, it is intended that all matter contained in the accomi panying specification and drawings shall be interpreted as illustrative and not in a limiting sense.

WVhat I claim as my invention is 1. A saw setting device comprising in combination an anvil member having a slot therein, a gage member mounted in the slot, means for clamping the gage member in adjusted position in said slot, a hammer member formed with a laterally extending tongue adapted to act as a spring, said tongue supporting the hammer member and being secured to the gage member and means for limiting the upward movement of the hammer member.

2. A saw-setting device comprising in combination an anvil member having a longitudinally extending slot in the normal upper surface thereof, a gage member slidsaid means extending laterally through a slot formed in one of the side Walls of the first mentioned slots, a hammer member supported by a plate spring formed integral therewith, said spring being secured to said plates on the side of the spring having engage member.

3. An improved saw setting device comprising an anvil member having a dovetail slot formed on the surface by two flanges, one of the flanges having a slot therethrough, a gage plate mounted in the dovetail slot, clamping'means on the gage plate extending through the slot in the flange on the anvil member and adapted to bear against the side of the anvil member, a hammer member, and means for supporting the hammer member from the gage plate with freedom to reciprocate to and from the anvil member.

l. An improved saw setting device comprising an anvil member, an adjustable gage plate thereon having dovetail slots in the sides thereof, a hammer member, a fiat spring supporting the hammer member and larged ends fitting the dovetail slots in the gage member.

In, Witness whereof I have hereunto se my hand in thepresence of tWO WIlSI'lGSSGS.
