UNITED STATES PATENT QFFICEO GEORGE N. CLEMSON, OF MIDDLETOIVN, NE\V YORK.

HAN DSAW.

SPECIFICATION forming part of Letters Patent No. 325,157, dated August 25, 1885.

Application filed May .20, 1885.

To all whom it may concern.-

Be it known that I, GEORGE N. CLEMSON, a citizen of the United States, residing at Mid dletown, in the county of Orange and State of New York, have invented certain new and useful Improvements in Saws; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

Figure 1 of the drawings is a representation of this invention, and is a perspective view. Fig. 2is a side view of the blade.

This invention relates to saws, and especially to that class of saws known to the trade as meat-saws, and it consists in the novel construction of the saw-blade which adapts it to be fitted to saw-frames of different sizes, as will be hereinafter fully described, and particularly pointed out in the claim.

Referring by letter to the accompanying drawings, A designates the frame of the saw, which is of ordinary construction employed in this class of saws.

Heretofore this class of saws have been riveted in the frames or bows, and when they became dulled they were resharpened in the bows. Consequently it was not necessary to remove the blade from the frame. By my improved construction the meat-saw may be sold at a price that renders it cheaper to use a new blade than to resharpen a dulled one. The bows or saw-frames are of varying lengths, and a single hole in each end of the saw-blade u will fit only a few of the frames in the market.

By providing a saw-blade that may be fitted to saw frames or bows of different sizes (No model.)

this difficulty is obviated, and this I have accomplished. I provide each saw-blade B with two holes, D C, at each end, so that it may be fitted to saw frames or bows of four different sizes, and by this construction I may remove a dulled saw-blade and insert a sharp one, which may beimmediately used, and, when dulled, may be replaced by a new blade.

I am aware that it is not new to provide a saw at opposite ends with two perforations, one arranged above the other, and that it is also old to arrange two perforations at opposite ends of a saw-blade on the same longitudinal plane; but in the latter construction a clamp or other suitable device is used for fastening the blade to the handle or holder, and the securing-bolts are in all of the perforations at the same time, which is not the object or manner of using my blade.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is

As an improved article of manufacture, a handsaw consisting of a bowed metallic frame, A, having its opposite ends kerfed and provided with a single transverse perforation, as shown, a blade, B, having the two outer perforations, O O, and two inner perforations, D D, on the same longitudinal plane, the said blade being secured to the frame by means of a pin, so as to leave an idle perforation at each end, whereby the blade is adapted for frames of various sizes, substantially as specified.

In testimony whereof I affix my signature in presence of two witnesses.
