Letters Patent Ng. 112,007, dated February 21, 1871.
IMPROV-EMENT IN BUCK-SAW FRAMES.
The Schedule lreferred to ln these Letters Patent and making part of the lame.
Description of the .Accompany/ing Drawing.
Figure 1 is a side view, partly in section, of my improved buck-saw;
Figure 2, a transverse section on the line 1 2, fig. 1; and
Figure 3, a perspective view, illustrating a modification otr' my invention.
General Description.
The frame ofthe saw has the usual curved strip B and handle D, of wood, which are connected together above by ordinary tightening-rods, E E, adapted to a screwcoupling nut e, and below by the saw-blade A.
The diagonal struts or braces G and H form a part of and serve to steady the frame, but are not connected together where they cross each othera plan adopted in some buck-saws-for I have found that a mnch'better result, as regards the general steadiness ofthe frame, may be attained by so constructing and arranging these braces that one shall have no control of the other where they cross.
l'Ihi's is accomplished, in the present instance, by
making one ofthe braces of three pieces, namely, the wooden strips h and h', and the double socket t', of metal, one of the stripsV being driven tightly into and secured to one end of the socket, and the other into directions that, under no circumstances, can one brace control the other where they cross. j
The braces are provided at their ends with simple tenons, fitting into corresponding mortises in the strip B and handle D, so that on tightening the tensionrod the 'braces will be lrmly secured in their places, the blade stretched, and the entire frame will be rigid and steady.
In place of a brace consisting of two strips and a double socket of metal, constructed as described above, two plain strips of wood may be used, provided they are arranged at a suitable distance apart to admit the counter-brace, as shown in iig. 3, and providing they are disconnected from the counter-brace.
