SAW-S ET.

SPECIFICATION forming part of Letters Patent No. 736,534, dated August 18, 1903.

Application filed August 22,1901- $erial No. 72,929. (No model.)

To all whom it may concern:

Be it known that I, JOSEPH MORIN, a citizen of the United States of America, and a resident of the city of Seattle, in the county of King and State of Washington, have invented certain new and useful Improvements in Hammer-Sets, of which the following is a specification.

My invention relates to improvements in hammer-sets for saws, and has special reference to a device of this class embodying means for setting, jointing, and gaging.

Among numerous objects attained by this invention is the production of a handy and durable tool for operating on the teeth of crosscut, drag, and the like saws and which embodies essential features of adaptability, efficiency, and adjustability which render it extremely useful and reduces time and labor in setting, jointing, and gaging saws.

The above-mentioned and other objects equally as desirable I attain by the construction,combinations,and arrangements of parts as disclosed on the accompanying drawings, set forth in the following specification and succinctly pointed out in the appended claims.

WVith reference to the drawings filed herewith and bearing like reference characters for corresponding parts throughout the several views, Figure 1 is a perspective view of my improved saw-set and indicates by broken lines the hammer reversed; Fig. 2, a side elevation of the device, on large scale, indicating by broken lines a file in relative position and the hammer reversed to clamp same in position for jointing; and Fig. 3, an edge view of the hammer removed from the shank and showing the adjustable gage.

This invention includes a suitable shank,

as 4, preferably rendered rectangular as viewed from the side and formed with one side edge, as 5, substantially smooth and true and a catch adjacent one end of said edge adapted to receive the end of a file and comprising in the present instance a laterallydisposed lug having a V-shaped notch in the inner side edge of suitable size to accommodate the stub end of a fiat file and to clamp same as forced therein. This shank is also preferably provided with suitable laterallyprojecting gaging-lugs, as 7, disposed on one side surface at suitable points adjacent catch 6 and are formed and used in the usual manner, and at the opposite end the shank is provided with a suitable anvil, as 8, adapted for cotiperation with ahammer9,operably mounted on said shank relatively thereto. The hammer 9 is preferably pivotally mounted for action on a suitable axis 10, fixed to a bracket 11, carried by shank 4 adjacent the forward end thereof and projected above the edge surface 5, and said hammer is suitably formed and positioned to act conjointly with said edge surface to clamp a file thereon when properly adjusted by partial rotation. As now considered, this hammer comprises a substan-' tially L-shaped body pivotally mounted 'sub-' stantially midway the length of the stem thereof,with the end of the foot portion adapted to receive impact of a suitable driver, as an ordinary hand-hammer, and the upper end of the stem adapted to clamp a file upon edge 5 when said body is properly turned, as indicated by dotted lines in Figs. 1 and 2, and thus bring the foot portion of the body into position for a firmer grasp of the hand to manipulate the device for jointing. As now considered, shank 4 and hammer 9 are rendered substantially equal in thickness, and bracket 11 is offset from the side of said shank which bears gaging-lugs 7, so as to leave the opposite side smooth to facilitate jointing action of the device, and the anvil 8 is suitably rendered by forming the upper portion of the adjacent end of said shank at a suitable angle to give the saw-teeth the proper set as forced by the action of the hammer which acts at the lower corner of the stem against said anvil.

At the forward end of shank 4 a suitable jaw 14 is fixed in relative position to the end surface of said shank to afford a slot, as 15, therebetween adapted to receive the sawteeth for action of hammer 9 and also for action of said device to spring the teeth, and said jaw terminates adjacent to the lower corner of anvil S to allow relative free action of said hammer. This jaw is preferably sup-. ported from bracket 11, which is suitably slotted transversely above slot 15 to allow the device to move freely along the saw with the teeth in said slot, and substantially midway the length of jaw 14 suitable recesses 17 are formed, one in the face thereof and one in the end surface of shank 4, to receive the set'portion of the saw-teeth when operating the device as a spring-set.

Related to anvil 8 is a suitable adjustable gage, as 18, adapted to insure regularity in setting the saw-teeth and preferably mounted on the stem of hammer 9 and formed with a head 19, adapted for contact with the point of the saw-teeth, and thereby limit their projection above said anvil. As now considered, this gage embodies a base 20, longitudinally movable on said stem and formed'with aslot 21, adapted to receive a suitable set-screw, as 22, engaged by suitable screw-threads with said stem and adapted to clamp the gage in adjusted positions. D

To operate this device as a hammer-set, it is grasped in one hand with the palm beneath the shank and an ordinary hand-hammer taken in the other. The deviceis then placed with the teeth of the saw in slot 15, and hammer 9 is adjusted to allow a respective sawtooth to project upwardly to engage head 19 of gage 18. ward slightly and the impact end of hammer 9 given a smart blow, which bends the respective saw-tooth outwardly against the face of anvil 8. This action is repeated for each tooth of a respective side and the shank then reversed, respectively, on the saw-blade to set the opposite teeth in a like manner. As a spring-set the device is operated by engaging a tooth in slot 15 with the set portion in a respective recess 17 and then pressing the shank upwardly or downwardly, as desired. In jointing a suitable file is placed on edge surface 5 with the stub end engaged in catch 6, Fig. 2, when hammer 9 is reversed to clamp same firmly upon said surface and the device is grasped with the hand about bracket 11 and the thumb lying along the upper edge surface of the foot of the hammer, whereby a firm hold is had to manipulate the file in the usual manner for jointing and the file insuredfrom slipping by pressure of the thumb on the hammer. To gage the set of the teeth, shank 4 is grasped and the lugs 7 presented to the side of the saw-blade in the usual From the foregoing it will be understood that this device presents numerous novel and advantageous features which reduce the labor ofsetting, jointing, and gaging saws, render such operations simple and readily understood, and set the teeth of the saw true and uniform.

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

1. In a device of the nature indicated; the combination with a shank having one side edge smooth, a catch at one end and an anvil at the opposite end; of a hammer pivotally mounted on said shank inoperable relations to said anvil and arranged to swing into fileclamping relation with said side edge.

2. In a device of the nature indicated; the

The device is then pressed up-' combination with a shank having one side edge smooth, a catch at one end and an anvil at the opposite end; of a substantially L- shaped hammer pivotally mounted on said shank by the stem above said side edge in operable relations to said anvil and adapted to swing into file-clamping relations with said side edge and present the foot for thumb-pressure.

3. In a device of the nature indicated; the combination with ashank havinga smooth upper side edge surface, a catch at one end, and the opposite upper end corner beveled to form an anvil and a jaw fixed relatively to said end with a slot therebetween; of an L-shaped hammer having a long and a short stem, the long stem being pivotally mounted'on said shank having the lower portion of its long st'em in cooperative relations with said anvil and the center of movement arranged to cause the opposite end of said long stem to come into file-clamping relations with said side edge when the hammer is swung.

at. In a device of the nature indicated; the

combination with a shank having smooth upper side edge surface, a catch at one end, the opposite upper end corner beveled to form an anvil and a bracket on one side surface projecting above said edge and beyond said anvil, of a jaw fixed to said bracket beyond the end of said shank, a recess in said end and in the opposing surface of the jaw, and an L- shaped hammer havingalongandashortstem pivotally mounted on said bracket and having the lower end of thelong stem in cooperative relations with the anvil and the center of movement arranged to bring the opposite end of said long stem into file-clamping relations with said edge surface when .the hammer is reversed.

5. In a device of the nature indicated; the combination with a shank having a smooth upper side edge surface, a file-catch at one end, gage-lugs on one side adjacent the catch, the opposite upper end corner of the shank beveled to form an, anvil and a bracket on the same side as said lugs projecting above said edge and beyond the anvil; of a jaw fixed to said bracket beyond the end of said shank, a recess in said end-and in the opposing surface of the jaw, an L-shaped hammer having a long and a short stem pivotally mounted intermediate of the long stem on said bracket with the lower end of the long stem in who erative relation with the anvil and the center of movement arranged to bring the opposite end of said long stem into file-clamping relations with said edge surface, and a gage to predetermine the length of the set portion of the saw-teeth adjustably mounted on said long stem relatively to the anvil.
