SAW-S ET.

SPECIFICATION forming part of Letters Patent No. 636,168, dated October 31, 1899.

Application filed July 2 '7, 1 8 9 9.

To all whom it may concern.-

Be it known that I, MATTHEW ODGERS, a citizen of the United States, residing in Philadelphia, Pennsylvania, have in vented certain Improvements in SaW'Sets, of which the following is a specification.

The object of my invention is to provide a simple form of saw set in which the saw is firmly clamped at a point adjacent to the toothed edge before the action of the settingdie upon the tooth, whereby the teeth of saws of different sizes can be accurately set. This object I attain in the manner hereinafter set forth, reference being had to the accompanying drawings, in which- Figure 1 represents a longitudinal section of a saw-set constructed in accordance with my invention. Fig. 2 is a transverse section on the line a a, Fig. 1; and Fig. 3 is an enlarged face view of the anvil forming part of the saw-set.

The body 1 of the saw-set is hollow and forms a guide for the two sliding dies 2 and 3, the former of which is a clamping-die and the latter a setting-die, operating in conjunction with an anvil 4, which is secured by a set-screw 5 to a jaw 6, which is located some distance beyond the end of the body-1 of the saw-set and is connected thereto by a curved arm 7, so that between the body 1 and the jaw 6 is' formed a throat for the reception of the toothed edge of the saw-blade. The anvil 4 has a series of setting-faces 4, four of which are shown in the present instance, each of these setting-faces having an extent of bevel differing from the others, as shown in Fig. 3, so that by turning the anvil in respect to the jaw 6 any desired setting-face 4 of the series may be brought into position to coact with the setting-die 3.

The inner end of the body 1 has depending flanges 8,between which are pivoted,by means of transverse pins 9, a pair of levers 10, the short arms of these, levers engaging with notches or recesses in the outer faces of the sliding dies 2 and 3, which are disposed back to back in the central opening of the body 1, as shown in Fig. 1. The long armsof the levers 10 form handles whereby the saw-set is manipulated, and these long arms of the levers are normally separated from each other Serial No. 725.296. (N0 model.)

by the action of an interposed coiled spring 11, so as to withdraw the dies 2 and 3 to their full extent. Contact of lugs 12 on the levers 10 with stops 13 on the body of the saw-set serves to limit the separation of the levers and the retraction of the dies.

To pins projecting from the sides of the body 1 of the saw-set are hung projecting ears 14 on gage-bars 15, located one on each side of said body, said gage-bars being connected by a cross-bar 16, which has a threaded opening for the reception of a set-screw 17, the latter bearing upon the rear face of the body 1, so that by the adjustment of this set-screw the gage-bars 15 can be caused to project more or less forwardly into the throat of the sawset, and can thus govern the set of the tooth by limiting the extent to which the latter is permitted to project over the beveled face of the anvil 4.

By the use of the clamping-die 2, working closely adjacent to the setting-die 3, the saw is clamped at a point close to the tooth before the action of the setting-die upon the latter.

also simple in construction and convenient of manipulation.

Having thus described my invention, I claim and 'desire to secure by Letters Patcut-- 1. The combination in a saW-set,of the body having a jaw located beyond the end of the same, and an arm connecting said jaw to the body, and a setting-anvil on said jaw having a broad flat bearing-surface for the saw-blade and a beveled surface for determining the set go of the tooth, and a pair of dies disposed back to back and guided in said body of the sawset, one of said dies being a clamping-die for the saw-blade and having a flat end opposed to the flat face of the setting-anvil and the other a setting-die having a beveled end operating in conjunction with the beveled face of the setting-anvil, substantially as specified.

2. The combination in a saw-set, of the hollow body having clamping and setting dies I00 guided therein, the end jaw having a settinganvil thereon, an arm connecting the end jaw levers, and lugs on the levers projecting 1011- gitudinally beyond said short arms and coop- I5 erating with stops on the body of the saw-set for limiting the extent of such separation, substantially as specified.

In testimony whereof I have signed my name to this specification in the presence of 20 two subscribing Witnesses.

MATTHEW ODGERS.
