SAW-HANDLE.

SPECIFICATION forming part of Letters Patent No. 236,925, dated January 25, 1881.

Application filed December 18, 1880. (No model.)

To all whom it may concern:

Be it known that I, JAMES R. WOODROUGH, of Cincinnati, Hamilton county, Ohio, have invented a new and" useful Improvement in Saw-Handles, of which the following is a specification.

The object of this invention is a cheap, durable saw-handle that can be readily attached to the blade and detached therefrom, and in which the blade will be securely and firmly held, and easily tightened should it become loose.

In the accompanying drawings, in which similar reference-letters indicate identical parts in the difierentviews, Figurel is a side elevation of. the attached handle. Fig. 2 is a longitudinal vertical section in front of the blade, and Fig. 3 is a transverse vertical section in front of the tightening-screw.

A is the handle of an ordinary handsaw. It may be formed after any approved pattern, in addition to the customary slit or kerf to receive the blade B. It has two transverse perforations, the lowerone to receive a plain pin, 0, which passes through-the handle and a perforation through the blade. The upperperforation registers with a perforation which is the enlarged termination of a slot cut from the upper edge of the saw-blade. The slot in the blade also registerswith a vertical perforation bored from the upper edge of the handle to meet the upper transverse perforation.

D is an angle-metal clip, made preferably of malleable cast metal. It firmly clasps the sides of the handle and rests upon the upper edge.

E is a screw, which passes through the top of clip D, the vertical perforation in handle A, the slot in blade B, and the semi-cylindrical nut F, which occupies the corresponding perforation in blade B and extends from each side of the blade intothe upper perforation in the handle. This perforation is large enough to allow the nut vertical play when actuated by its screw.

The blade and handle are secured together as follows: The blade is first inserted in the kerf in the handle, the rivet G and nut F inserted, and the clip D forced over the handle, claspin g the blade firmly upon each side. The screw E is now inserted and tightened, straining the heel of the blade between rivet or pin 0 and nut F.

It will be seen that there is but one screw in my handle, and if this should work loose, as all screws are liable to do, it can be quickly tightened with an ordinary screw-driver, and should the wooden part of the handle, by a fall or other accident, be broken, it can be readily replaced by the workman' with little expense and trouble.

My handle maybe given a highly ornamental finish without much additional expense by extending the sides of clip D and forming them into fanciful shapes.

A better handle than those in common use may be made by omitting the clip D or its clasping-sides and using simply the lower fastening-pin and the upper tightening-screw and its anchor-nut, with a plate or washer under the head to protect the wood of the handle.

My anchor tightening device may also be used to draw the edge of the saw against an upper plate or the end of the kerf, if not out through the handle.

I claim 1. In a handsaw, the combination of handle A and blade B, slotted as shown, with a tightening device consisting of screw E and anchor-nut F, substantially as specified.

2. In a handsaw, the combination, substan- 8o tially as hereinbefore set forth, of handle A and bladeB with pin 0 and an upper tighten ing screw and nut, as E F, drawing against said pin.

3. The combination, substantially as herein- 85 before set forth, of handle A and blade B with clip D, pin 0, screw E, and nut F.
