SAW-HANDLE.

SPECIFICATION forming part of Letters Patent No. 270,419, dated January 9, 1883.

Application tiled October 10. No model.

To all whom it may concern Be it known that I, BENJAMIN GoUL'roN, of"

- Kaco. Wangaroa, in the county of Man gonui,

in g-catch, preferably made automatic by means ofa spring, for securing said handle or handle socket to the end of the saw, substantially as hereinafter specified.

Reference is to be had to the accoin mnying drawings, forming part of this specification, in which similar letters of reference indicate corresponding partsin all the figures.

Figure 1 represents a side view of the one end portion of a erosscut-saw constructed in accordance with the invention. Fig. 2 is a farther side view of the same with the handle in course of being titted to its place; and Fig. 5, a side view, showing the handle as secured in position on the end of the saw. Fig.4 is a longitudinal section, in part, on the line {U ain Fig. 3; and Fig. 5, a farther longitudinal section, in part, on the line 3 y in Fig. 3. Fig. 6 is a side view of the one end portion of apitsaw, showing a modified construction for va rying the position of the handle.

Although my invention is only shown in the drawings as applied to the one end of a saw, it will readily be understood that both ends are or may be alike.

Theinvention is more particularly intended for crosscut saws, but, as already stated, is also applicable to other saws.

The handle is mainly constructed of thin metal plates, and slips onto the end of the saw or receives the end of the saw within it as other loose handles of crosscnt-saws have been fitted; but it importantly differs in the means Patented in New Zealand Mart-h 6, 1882, No. Go].

provided for attaching it to and detaching it from the saw.

Referring in the first instance to the first five figures of the drawings,either end portion of the saw A has a slot, I), cut or formed in it from the front edge of the saw toward the back thereof, or at right angles to the length of the saw, thesame presenting an open end where it joins the cutting-edge of the saw. It also has another, and itmay be smaller, open outer ended slot, 0, formed in its edge and running in direction of thelength of the sawylikewise has a shoulder projection, s, on said end edge between the slot 0 and the back edge of the saw.

B is the handle or metalsocketportion thereof, constructed atits inner end to slip over or receive within it the end of the saw, and provided at its back or outer end with the usual hand-gri ppingcross-bar (I. Said handle-socket is provided at itsjaw or sawreceiving end with across rivet or pin, 0, arranged to fit or play within the slot I) when the whole handle is being fitted to its place, as shown in Fig. 2. The whole handle then turns by this pin 0 as a pivot within and against the back end of the slot 1) till it is brought into its proper closed position relatively to the end of the saw, as shown in Fig. 3, when it is secured or locked byacrosspin or proiection, on a slide, 0, shootinginto engagement with the slotc in the end edge portion of the saw. The slide 0, which carries the pin j", that works through and along a slot, g, in the.handle-socket 13, is fitted to hug the outsides of said socket, and is connected by a cross-pin, It, which passes through another slot, 1', in the socket and serves as a bolster for a spring, 7;, to press against and urge the slide (J forward. In this way the whole handle be comes self-locking, as it is adjusted into position, by first entering the pin 0 within the slot 1) and turning the handle up till it is arrested by striking the shoulder projection s. In the working of the saw there will he no tendency of the handle to get loose, as the strain comes entirely upon the pin 6 and not upon the slide U or its locking-pin], and by simply drawing back the. slide 0 the whole handle, on being pressed down, is readily detached from the saw when required.

By the construction of the handle and end of the saw, as described, the handle becomes self-adjusting in its lit to the. saw, and the spring 7. not only provides for its being selflocking, but for holding itin place. ltd'esired, said spring might be dispensed with, and the slide C he slid forward by hand and be secured by a set-screw or otherwise from slipping back. A spring-catch, however, which the slide with its locking-pin and spring forms. is preferable.

Fig. (i of the drawings shows the end ot a pit-saw, A, as formed with duplicate slots 1; I, the one of which projects inward from the cut ting-edge of the saw, and the other from the back edge thereof; also shows duplicate slots 0 c in the end edge ol the saw, with the shoulder projection a between them. This construc tion provides tor the handle '3, with its accompanying slide (fl, and pins 0 f being attached closer either to the front or back edge of the saw, as the work ma. require.

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

1. The saw ldade A, having a shoulder, s, and slot 0 in its end, a slot, 1), in its side, and the ad acent corner cut away, ha ring; the corner ot' the. blade of the saw curved in the are of a circle from the inner end of slot I) as a center, as and for the purpose specified.

2. The c mbination, with the saw ;\,|l'|\"lll a shoulder, J, an end slot, 0, a slide slot, 1), and the adjacent corner rounded. ol' the handle or socket ll,providedwith the fixed pin 0,11 sliding pin.f, and a shoulde adapted to lit shoulder J at the same time that said pins eand ffit in the slots I; and 0, respet'atively, as and For the pur 'iose specified.

J). The combination, wi h the .raw or saw blade A, having open-ended slots I 0, arranged at right angles to 621,011 other, or thereabout, as described, ot' the handle or handle-socket I provided with a cross-pin, for fit within the slot 1) ol' the saw, and a spring-catch, C. arranged to engage with or in the slot (5 ot the saw, substantially as specified.

The foregoing specification ot' my improvea meat signed by me this 2lst day of July,'l882.
