SAW SET Filed June 19, 1945 EDWIN F. HUFFSMITH,

Patented Oct. 22, 1946 UNITED STATES PATENT OFFICE SAW SET Edwin Franklin Hufismith, Cook, Wash.

Application June 19, 1945, Serial No. 600,287

3 Claims. 1

The present invention relates to new and useful improvements in saw sets, and more particularly to a device of this character adapted for setting the teeth of chain saws and embodying means for setting the teeth at opposite sides of the saw.

The invention is designed particularly for use in the setting of the teeth of a chain saw while the saw is clamped in position on a saw-filing bench, and the invention embodies the provision of an anvil adapted for positioning at either side of the saw and hammers adapted for use at the respective sides of the saw and adapted upon delivery of an impact to the hammers to set the teeth at a desired angle.

A further object of the invention is to provide a device of this character of simple and practical construction, which is efiicient and reliable in use, relatively inexpensive to manufacture, strong and durable, and otherwise well adapted for the purposes for which the same is intended.

Other objects and advantages reside in the details of construction and operation, as more fully hereinafter described and claimed, reference being had to the accompanying drawing forming part hereof, wherein like numerals refer to like parts throughout, and in which:

Figure 1 is a front elevational view with parts broken away and shown in section.

Figure 2 is a side elevational view.

Figure 3 is a sectional view taken substantially on a line 33 of Figure 1.

Referring now to the drawing in detail, wherein for the purpose of illustration I have disclosed a preferred embodiment of the invention, the numeral 5 designates an anvil having one end formed with oppositely inclined striking faces 6 and I and having its opposite end tapered to form a handle 8 by means of which the striking faces of the anvil may be held against the side of a chain saw 9 while the saw is held with its upper flight secured in a stationary position by means of a clamping plate I of a saw-filing bench.

The lower portion of the anvil is of a straight construction, as indicated at II in Figure 3 of the drawing, for bearing in confronting relation against the base of the teeth 9 of the saw, and the straight lower surface I I of the anvil is formed with a horizontally extending groove I2 adapted to accommodate the rivets I3 used for pivotally connecting the teeth of the saw while the anvil is slidably moved against one side of the saw.

Upper and lower bolts I4 and I5 extend transthe hammer I9.

versely of the anvil 5 and a pair of upwardly and forwardly curved arms I6 are provided with slots I1 in their loweri portions for receiving the ends of the bolts for vertically adjusting the arms at opposite sides of the anvil.

A bolt I8 extends transversely at the upper ends of the arms I6 and constitutes a shaft supported between the upper ends of the arms and on which a pair of hammers I9 and 20 are swingably mounted by hangers 2| and 22 projecting upwardly from the hammers. The hammers are secured in spaced relation on the bolt I8 by means of spacing washers 23.

The striking face 24 of the hammer I9 is inclined in the plane of the inclined face 6 of the anvil, while the striking face 25 of the hammer 20 is inclined in the plane of the face I of the anvil, as will be apparent from an inspection of Figure 3 of the drawing.

In the operation of the device, the lower front edge of the anvil 5 is positioned on the upper edge of the clamping plate In at one side of the chain 9 and with the inclined face 6 of the anvil bearing against one side of the teeth of the chain. A hammer blow is then struck against the hammer I9 whereby to set the teeth of the saw in accordance with the inclination of the face 6 of the anvil and the striking face 24 of The device is moved along the side of the saw for setting the alternate teeth by the hammer I9 and the device is then positioned at the opposite side of the saw and the remaining teeth set by the hammer 20 and inclined face I of the anvil.

It is believed that the details of construction, manner of use and advantages of the device will be readily understood from the foregoing without further detailed explanation.

It is to be understood, however, that even though I have herein shown and described a preferred embodiment of my invention, the same is susceptible of certain changes fully comprebended by the spirit of the invention as herein described, and the scope of the appended claims.

Having thus described the invention, what I claim is:

1. A saw set comprising an anvil adapted for holding against either side of a saw and having oppositely inclined anvil faces for oppositely setting the teeth at the respective sides of a saw, a pair of arms rising from the anvil in spaced relation to each other, a shaft supported at the upper ends of the arms, and a pair of hammers swinga-bly mounted on said shaft for striking the teeth of the saw, said hammers having striking faces inclined in the plane of the respective anvil faces.

2. A saw set comprising an anvil adapted for holding against either side of a saw and having oppositely incline-d anvil faces for oppositely setting the teeth at the respective sides of a saw, a pair of arms rising from the anvil in spaced relation to each other, means for securing the arms in vertically adjusted position on the anvil, a shaft supported at the upper ends of the arms, and a pair of hammers swingably mounted on said shaft for striking the teeth of the saw, said hammers having striking faces inclined in the plane of the respective anvil faces.

3. A saw set comprising an anvil including a handle for holding the anvil against either side of a saw, said anvil having a straight transverse lower front portion and oppositely inclined upper front portions for oppositely setting the teeth at the respective sides of a saw, a pair of upwardly and forwardly extending arms secured at the opposite sides of the anvil, a shaft supported at the upper ends of the arms, and a pair of hammers swingably mounted on said shaft for striking the sides of the teeth of the saw, said hammers having striking faces inclined in the plane of the respective anvil faces.
