WALLACE E. MOKIE, OF TELLURIDE, COLORADO.

SAW-

SET.

SPEGIFIGATION forming part of Letters Patent No. 673,446, dated May '7, 1901.

Application filed October 5. 1899- To [LZZ whom. it may concern:

Be it known that I, WALLACE E. h/ICKIE, a citizen of the United States, residing at Telluride, in the county of San Miguel and State of Colorado, have invented certain new and useful Improvements in Saw-Sets, of which the following is a specification.

My invention relates to a saw-setting device, the object being to provide an effective and durable saw-set which will be simple in construction and capable of being manufactured at small expense.

The construction of the improvement will be fully described hereinafter in connection with the accompanying drawings, which form a part of this specification, and its novel features claimed.

In the drawings, Figure 1 is a side elevation of a saw-set embodying the invention. Fig. 2 is a top plan view of the same. Fig. 3 is a detail vertical section showing the anvil and its support. Fig. 4 is a reverse plan view of the guide which engages the saw-teeth, and Fig. 5 is a section on the line 5 5 of Fig. 1.

The reference-numeral 1 designates the base-plate of the device, provided atits front end with depending lugs or flanges 2, formed with openings for the reception of set-screws for securing the base 1 to a bench or other support. An arm 3, having an opening for a set-screw 4, projects from the front end of the base 1.

The base 1 is formed near its front end with a rectangular opening 5 and is recessed at its rear end to form parallel arms 6 and 7, to the rear end of each of which is secured a bracket 8. Set-screws 9 pass through these brackets to serve as stops for the lever 10, which carries the hammer of the device. This lever 10 is formed at its rear end with diverging arms 11, provided with openings for the passage of a shaft 12, which is supported in bearings of the parallel arms 6 and 7 and constitutes the pivotal support or fulcrum of the lever. Around the shaft 12 is located a coil-spring 13, the ends 14 of which rest, respectively, on the upper side of one of the arms 11 and on the under surface of the base, as shown in Fig. 2. The front end of the lever is rounded at its upper surface and formed with a projecting handle 15, and one side of the front Serial No. 732,681. (No model.)

end or head of the lever is formed with a circular recess 16, within which is removably and adjustably secured a circular hammer 17. This hammer is formed with equidistant peripheral notches, which divide the periphery into independent striking-surfaces 18. The outer side of the hammer is beveled for a portion of its area, as shown in Figs. 1 and 5, which reduces the thickness of a part of the hammer, as at 19, and adapts the hammer for saw-teeth of varying width. The hammer is secured to the lever by a set-screw 20, passing through a central opening in the hammer and a corresponding hole in the head of the lever.

The front end of the base 1 is provided with a semicircular projection or extension 21 and with a circular socket 22, formed with a shoul der 23. Within the socket 22 is rotatably supported an anvil-block 24, formed with a shoulder 25, which rests upon the shoulder 23 of the socket and having its upper surface beveled, as shown, entirely across the block.

26 and 27 designate guide-bars extending across the base 1, in rear of the anvil, to serve as guides for the saw.

Adjacent to the end of the guide-bar 27 is a guide 28, comprisinga pointer formed with an opening 29 for the reception of a screw 30 and with a prong or sharpened projection 31, adapted to enter the spaces between the sawteeth. From the under surface of the rear end of the pointer depends a lug or pin 32, adapted to slide in a longitudinal slot 33, formed in the base 1. The pointer-guide may thus be adjusted longitudinally or at right angles to the saw.

The anvil 24 is held in place by a setscrew 34.

35 designates a block supported upon the base 1 and hollowed out on its upper surface to receive a block 36, of rubber or other yielding material, to avoid shock or jar in the op eration of the lever by cushioning its stroke.

The operation of the device will be readily understood. The saw to be set is laid transversely upon the base, resting upon the anvil 24, with one of its teeth in position to be struck by the hammer 17, which is adjusted upon its axial support to present the proper strikingsurface opposite the anvil. The

pointer 28 is adjusted so that its prong 31 will enter between the teeth and assist in holding the saw in proper position.

I claim- A saw-set comprising a base-plate formed integral with depending lugs at the'front end with an extension in front of the lugs having a shouldered circular socket and a supporting-arm with transverse guides, with parallel arms at the rear end, each having a bracket with a side slot and with a central block having a socket, the spring-lever fulcrumed to the parallel arms having a head formed with a circular recess, a circular hammer having peripheral notches, set-screw for securing the hammer in the circular recess, the pair of set-screws working in the brackets and acting as stops for the lever, a cushioning-block for the lever, located in the central block, the anvil formed with a shoulder and having its upper surface beveled entirely across the block, and seated in the shouldered circular socket, a set-screw for securing the anvil, a set-screw in the supporting-arm for supporting the saw, a guide-bar having'a pin at its rear end and engaging in the side slot and a pointer at its forward end, and a set-screw for securing the guide-bar.

In testimony whereof I aifix my signature in presence of two witnesses.

WALLACE E. MCKIE.
