Specication forming part of Letters Patent No. 123,556, dated February 13, 1872.
I, WILLIAM. GLnMsoN, of Middletown, in the county oi' Orange, in the State of New York, have made certain Improvements in Buck-Saw Frames, ot' which the following is a speciiication:
The object of this invention is to cheapen, and at the same time strengthen, the frame without increasing its weight or cost; and it consists in the construction and arrangement ofthe several parts that compose the frame, as will more fully hereinafter be described.
In the drawing, Figure lrepresents in side view the saw-traine and its severa-l parts.
A is the hand-end ot' the frame. A' is the opposite end of the frame. B is the i'ulcrumbrace or cross-bar between the end pieces A and A'. C is the saw, one end otl which is inserted in the end piece A', in the usual manner, and held by pin d, while the other end has a screw-rod, c, attached, and passes through end piece A, with a thumb-nut, c', thereon, and by which the saw is strained. b b are simple straight rods ot' metal wire, put into holes that 'go obliquely through the end pieces A and A', and through brace B. These rods b b go through the end piecesA and A', above the brace B, and thence obliquely through the brace B, as seen in Fig. 1,and are so inserted for the purpose of strengthening andstiftening the joint where the brace B enters the end pieces A and A'. I,
As will be seen,the joints made by the brace B and the end pieces A andA', are not aiiected by the straining of the saw by turning up the thumb-nut c' against the end piece A, for while. thus contracting orforcing the end pieces toward each other, the oblique direction at which the rods b go through both the end pieces A and A' and brace or bar B prevents the opening of the joint on the upper side of the brace B, by reason of the rod b being` clamped both in the end pieces and brace the moment the lower ends of the end pieces are made to approach each other, causing an upward de ilection of the brace or bar B by the Vpulling action of the rods b,- consequently causing the frame to become rigid and unyielding, and in consequence ot' which condition the end pieces A and A' may be much smaller and lighter, and A' shorter, or not projecting so far above the straiirbrace as A, as is the case in other constructions, which will reduce the expense ofthe frame in proportion as the wood is less.
This invention is an improvement upon the frame patented to lne October l0, 1871, in which was used common wood screws to strengthen and hold the joints in contact, as in practice it isi'ound ythat the screw is wholly unnecessary, asa simple plain piece ot' wire will answer every pui-pose of the screw, and being cheaper in its cost will necessarily cheapen the fra-me without in any way taking from it any ofthe advantages described in said patent, in which a screw is used; and by my present iinproveinent, as herein described, I do away with the strain-rod at the upper end of the fra-me, tha-t was necessary in the patent cited.
l I am aware of the patent dated July 5,1870, to E. M. Boynton, for a saw-frame, and I disclaim the construction therein shown, as the saw-traine in that patent is heavy and cumbersome, it having two cross-bars through which pass the diagonal rods before entering the end pieces. lVhile in my fra-mc there is but a single cross-bar, through which and the end pieces the diagonal rods go, while the lower end piece is much shorter, thereby making a lighter and better-balanced frame, as well as arnuch cheaper one.
Having thus described my invention, what I claim, and desire to secure by Letters Patent, 1s-
The combination of the end pieces A A', cross-bar B, and diagonal rods b b, constructed and arranged to form the frame of a bucksaw, as shown and described.
