SPECIFICATION forming part of Letters Patent No. 302,100, dated July 15, 1884, Application filed December 26. 1883. (N model.) 7
To all whom it may cmwern:
Be it known that I, MYRON CASE, of Kasoag,
in the county of Oswego and State of New York,
have invented a new and Improved Buck-Saw, of which the following is a full, clear, and exact description.
My invention consists of an improved con-.
saw frame having'acombined brace and.
strainer arranged accordingfto the principle of my invention. Fig. 2 is a side elevation with some parts in section and modified to some extent, and Fig. 3 is a detail view.
In the place of the usual bar of the frame, located about midway between the saw a and the top cord, 1), I arrange acombined brace and strainer consisting of a thrust-bar, c, and a lever-bar, d, bar a being mortised into the lower end bar, f, of the frame rather slack, and ex;
tending nearly to the upper end bar, 9, and
pivoted or otherwise jointed to the bar d, which is pivoted to the upper end bar, 9, at h, and
extends diagonally therefrom to the upper end of the lower frame-bar, f, with which it connects by a suitable binding device, so as to shift along and be secured at any point to said end barf. In Fig. 1 said bar 01 consists of two parallel parts, which embrace bars 9, c, and f,
and extend beyond the latter with a connecting-pin, h, each side, and with a wedge, i, between the inside of barf and thepin h of that side, the wedge being to hold bar d down to any'position it may be set to for tightening the frame by applying end-thrust to bar 0. Bar 11 may be secured by a grip-yoke, j, fitted to the end to swing up and down along bar 7",
and bind thereon by the pull of theupward stress of the bar d, said bar 01 terminating in this case. inside of the end bar f.
To'take up the slack from time to time that comes from the spring of the bars f and bar d may have a series of holes for shifting the pivot-pin it along it; or the pin kmay be adjustable along either bar 61 or c,- or bar 0 may have a slot in the end for pink, which may be packed out from time to timeby pieces of leather qor other material placed in the slot behind the pin; but I propose in practice to make the bar 0 extensible in any way, with a cam, Z, pivoted on one part and bearing against the end, or a shoulder or pin of the other part, so that the bar may be extended readily at any time by shifting the cam a little. For this purpose the cam Z may be set in a slot of one of the sectionsof the bar, in which slot abar, 1), may be located with one end against the face of the cam, and near the other end said bar may be connected with a pin, m, extending through slots n of the sides of thepart of the bar 0, containing the cam, and connecting with the part c, that is connected to the leverbar. In this case said part c of the thrust-bar may connect with lever-bar d by bearing at the I do not limit myself to any particular ari rangement of the extensible thrust-bar, nor to the construction and arrangement of the leverbar.
.I am aware that the end bars of a buck-saw have been provided with a thrust-bar and piv: oted straining-lever connected together, and said lever adjustable on the top cross-piece of the frame by a pin and-series of holes, and I do not claim such, broadly, as of my invention.
Having thus described my invention,what I claim as new,and desire to secure by Letters Patent, 'isi 1. The thrust-bar located between the saw a and the top cord, 1), in abuck-sa'w frame, having one end movably connected to aleverbar, d, and the other end connected to the lower end bar, f, and saidlever-bar d pivoted to end bar 9, and arranged to swing along and be secured to barf by aimovable binding device near the outer. end of said lever, sub
stantially as described. v
2. A bucksaw frame provided with a thrustbar, 0, and a pivoted lever, (1, adjustable with respect to each other, whereby any slack in the frame may 'be taken up, substantially as set forth.
3. The combination of an extensible thrustbar, 0 c, and an adjusting-cam thereon, with the lcvenbard and the end barsfg of a bucksaw frame, substantially as described.
4. In a saw-buck frame,the extensible thrustbar 0 0 and operating-cam Z, in combination with the lever d, pivoted to thenpper end bar, 7, inovably connected with the said thrust-bar, and adjustably connected with the lower end
