TOOL-HANDLE.

SPECIFICATION forming part of Letters Patent No. 403,832, dated May 21, 1889.

Application filed July 17, 1888. Serial No. 280,164- (No model.)

To all whom it may concern.-

Be it known that 1, CHARLES DWIGHT FUL- LER, a citizen of the United States, residing at Minneapolis, in the county of Hennepin and State of Minnesota, have invented new and useful Improvements in Tool-Handles, of which the following is a specification.

The invention relates to improvements in tool-handles.

The object of the invention is to protect the handles of chisels and other tools and prevent them from splitting under the blows of a mallet or hammer.

Heretofore metal caps have been employed to protect tool-handles and prevent them being split by the blows of a hammer or mallet; but such caps have been of specific construction, and were adapted only for a particular class of tool-handles. Metal caps have also been provided upon tool-handles to enable the tools to be used as hammers.

The invention consists in the novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claim hereto appended.

In the drawings, Figure 1 is a central longitudinal view of a tool-handle constructed in accordance with this invention. Fig. 2 is a detail perspective View of the cap.

Referring to the drawings, A designates a wooden body of a tool-handle, which may, as illustrated in the drawings, be a chisel-handle or any other tool-handle that is designed to be subjected to blows of a hammer or mallet. The end is provided with a screwthreaded projection, (1, upon which is screwed a metal cap, B, whereby the end of the handle is protected from injury by the blows of a hammer or mallet. The screw-threaded projection a is formed integral with the handle A, as illustrated in Fig. l of the accompanying drawings, and leaves a broad flat annular bearing-surface, a upon each side of it for the cap.

The cap B is constructed of suitable metal and has an internally-threaded recess, b, which is adapted for the reception of the screw-threaded projection a of the handle A, whereby the metal cap B is secured to said handle A. Around the lower edge of the metal cap B is a flange, b, which, when the metal cap B is screwed in place, fits in a circumferential rabbet, a, formed in the handle, and between this peripheral flange b and the screw-threaded recess Z) is an annular shoulder, 12 designed to engage the annular bearing-surface a of the body A. The circumferential flange 1) acts as a ferrule, and when the cap is screwed in place the wood is compressed, which compression effectually prevents the extreme edge of the handle splitting off, and the construction of the base of the cap forms a broad bearing-surface. The metal cap B is constructed solid, and the force of a blow is thereby diminished before it is transmitted to the wooden portion of the handle A.

Of course I desire it to be understood that I do not limit myself to the precise details of construction herein shown and described, as I may, Without departing from the spirit of the invention, make any minor changes therein.

From the foregoing description and the accompanying drawings it will readily be seen that the metal caps constructed in accordance with my invention are applicable to any form of tool-handle and are fully capable of protecting them from injury from blows of a hammer or mallet.

Having described my invention, I claim In a tool-handle, the combination, with the wooden body having its ends circumferentially rabbeted and provided with a central screw-threaded projection, and a flat annular bearing-surface at the base of said projection, of a metal cap having a threaded recess to receive the projection of the wooden body, a flat annular shoulder at the base of the cap surrounding the threaded recess, and a peripheral flange tapering from the annular shoulder, whereby, when the cap is screwed in place, the wood at the end will be compressed and prevented from splitting, substantially as described.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in presence of two witnesses.

CHARLES DWIGHT FULLER.
