BUCKSAW.

SPECIFICATION forming part of Letters Patent N0. 623,588, dated April 25, 1899.

Application filed April 25, 1898. Serial No. 678,822. (No model.)

To all whom it may concern:

Be it known that I, PETER WooDRINo, a citizen of the United States, residing at Oelwein, in the county of Fayette and State of Iowa, have. invented a new and useful Bucksaw, of which the following is a specification.

Heretofore braces for bucksaw-fram es have been reduced in size and strength at their centers to overlie each other in crossed position and perforated to be clamped together by means of a screw-bolt extended through the perforations.

My object is to avoid reducing the strength of stays and to facilitate connecting and disconnecting the different parts of a frame as required to economize space in packing and shipping and in regulating the tension of the saw-blade for practical use.

My invention consists in the construction, arrangement, and combination of mating Wooden braces with a metal clamp, wooden uprights or end pieces of common form, and a saw-blade, as hereinafter set forth, pointed out in my claim, and illustrated in the accompanying drawings, in which- Figure 1 is a side View, and Fig. 2 an edge view, of one of the mating braces. Fig. 3 isa modification of Fig. 1, showing the brace bent and of uniform thickness from end to end. Fig. 4 shows the complete saw and themating braces clamped together in crossed position at their centers. Fig. 5 isa modification of Fig. 4., showing the upper ends of the mating braces mortised and tenons on the ends of the frame. Fig. (3 is a sectional view on the dotted line 00 a: in Fig. 4:, showing the form of the metal clamp andthe manner of its application.

The letter A designates a brace that is reduced in thickness'at its central portion, as

shown in Fig. 2, and wider at its central portion, as shown in Fig. 1, so that it has as much wood and is practically as strong at its center as at its end portions, and when two matingtightener, as required to stiffen the complete frame and to regulate the tension of the sawblade fixed to the frame.

Fig. 3 shows a brace A of uniform thickness from end to end and sufficientlybent or bowed laterally so that when two mating braces are connected with the end pieces of the frame, as shown in Fig. 4E, and clamped together at their centers, as shown in Fig. 5, the-ends of the braces will be in the same plane and in alinement with each other and the upright end pieces B and O, to which the ends of the braces are connected by means of mortises and tenons.

D isa frame-tightener consisting of a metal rod and turnbuckle, havingloops on its ends adapted to slip over the top corners of the frame in such a manner that the frame may be thereby stiffened and the tension of the saw-blade F regulated by the operation of the turnbuckle in a common way.

H is a U -shaped spring-metal clamp adapted to be placed astride of the mating braces at the point where they cross each other. The ends of the clamp have coinciding perforations, through which a screw-bolt J is passed, and by means of a Winged nut on the end of the bolt the braces-can be rigidly pressed and clamped together to retain all parts of the complete frame rigidly fixed together.

It is obvious that all the parts of the frame and the saw-blade can be readily separated and placed together and into a compact bundle and small space to facilitate packingand storing and economize space and expense in shipping. stays in a crossed position by means of a flexible spring-metal clamp and a screw-bolt and nut the clamp is conformed to the convex surfaces of the stays, as required to bind them firmly in fixed positions and to maintain the frame rigid when in use.

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

In a bucksaw-frame, the combination of two mating wooden stays that are unimpaired at their central portions by removal of wood, a flexible U-shaped metal clamp having coinciding bolt-holes in its ends and a screwbolt and nut, as and for the purposes set forth.
