SAW- HAN DLE.

SPECIFICATION formingpart of Letters Patent No. 272,007, dated February 6, 1883.

i Application filed August 10, 1882. (N model.)

To all whom it may concern:

Be it known that I, JAMES R. WOODROUGH,

a citizen of the United States, residing at Gincinnati, county of Hamilton, State of Ohio, have invented certain new and useful Improvements in Saw-Handles, of which the following is a specification.

This invention relates particularly to handles for key-hole saws. Its object is a cheap, secure means to readily attach and detach the blade and handle, and which will also serve to strengthen the handle and prevent it from splitting. I

In the accompanying drawings, in which like parts are represented by similar referenceletters in both views, Figure 1 is a side elevation ofkey-holesaw provided with myimproved blade removable fastening device. Fig. 2 is a perspective view, drawn to about full size, of my fastening-clip detached from the handle and having the tightening-screw removed.

A represents the common wooden handle, slotted back, as usual, from the forward end to dotted line ato receive the ordinary blade, B, whichis pushed back to the end of the slot. The removable fasteningclip consists of two rings, 0 O, which are united by a web, D, the. whole being made in one piece, and preferably of cast malleable metal. The web D is perforated and tapped to receive the fasteningscrew E. When the blade is inserted in the handle A and. the clip pushed back over the end of the handle, as seen in Fig. 1, the screw E is tightened down upon the top edge of the blade, and, the screw being greater in diameterthan the slot in the handle, it will embed itself slightly .in the wood and hold the clip in place upon the handle, while holding the blade firmly between the rings 0 and the end of the screw.

I am aware that it is not new to provide a saw-handlewith a permanently-fixed ferrule having a set-screw to clamp the blade to the V handle. This arrangement requires that the end of the saw handle be specially constructed to fit the ferrule, and in the event of the bandle being broken the ferrule is thrown away.

By my improvement I am enabled to use any saw-handle of ordinary construction as it comes from the factory, either before or after it is provided with transverse bolt-holes; andI am also enabled to use any ordinarily-constructed sawblade, and should either the blade or the handle be broken the broken member can be readily replaced by anew one, as, with my removable fastening-clip, neither the blades or handles require special preparation, as they did to be used with the fixed ferrules heretofore known.
