IMPROVEMENT IN SAW-FRAMES.

. Specification forming part of Letters Patent No. 94,500, dated September 7, 1869 5 reissue N o. 4,276, dated February Q1, 1871; reissue No. 5,674, dated December 2, 1873; application led November 17, 1873.

To all whom it may concern Be it known that DANIEL MOORE and ED- WIN MUORE, of the city of Brooklyn, E. D., county of Kings and State of New York, have invented certain new and useful Improvements in Saw-Frames.

This invention is for the combination of a brace, frame, saw, and tightener, as will be hereinafter described; and the following is a full, clear, and exact description thereof, Which will enable others skilled in the art to which it appertains to make and use the saine, reference being had to the accompanying drawings, with letters of reference marked thereon,

forming a part of this specification, in Which- Figure l represents a side elevation partly in section, and Fig. 2 represents a section of one of the joints.

A represents the handle portion of the saW- frame. A represents the opposite portion of the frame '5 B, the saw, and c, the tightener for drawing the upper ends of the saw-frame together. This tightener is shown as made of rods with looped ends passing into inort-ises in the upper ends of the frames A A, the rods having right-and-left-hand screw-threads on them, taking the shackle f. The thrust-brace is made with ends, as seen at cl, constructed to lit corresponding mortises or recesses c in the faces or inner edges of the frame sides A A. This thrust-brace D is shown as being formed of aros of circles a b, land the straining of the saw is effected by forcing the stretcher b into brace ca is shown as attached near the middle to the stretcher b, and the ends enterthe mortises or recesseslin the frames A A. These stretchers a and b form arcs of circles, the con- Vex sides being placed together; hence, when the tightener e draws the ends of a toward each other and make the same the arc of a smaller circle, the stretcher b will be forced into a more nearly straight form straining the saW by pressing against the inner edges ot' the frames A A.

A saw-frame with a single stretcher is not claimed; neither a thrust-brace and diagonal bar; nor a pair of tension-braces and a thrustbrace; but,

Having thus fully described the invention, what is claimed, and desired to be secured by Letters Patent, is-

The frame sidesA A', a saw, B, and a tightener, e, in combination With the thrust-brace D, having the four points of bearing in the frames A A', between the tightener and saw,

vsubstantially as and for the purpose specified.
