TOOL-HAN DLE.

Specification of Letters Patent.

Patented Oct. 4, 1921.

Application filed April 30, 1921. Serial No. 465,674.

T 0 all whom it m ag/ concern y Beit knownY that I, JoiiN P. DoMAN, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented certain new and useful Improvements in Tool-Handles` of which the following is a specification.

My invention relates to tool handles and more particularly to such tool. handles as are intended to be struck by a hammer or similar means when in use. for inst-ance., a carpenters or cabinet makers chisel.

An object. of the invention is to provide such a tool with a Wooden handle which can withstand the hard usage to which it is necessarily put.

Another object of the invention is to provide such a handle which is neat and shapely in appearance and one which can be manufactured at small cost.

In practice it is customary to provide such tools with wooden handles` and even though made of the hardest wood they are quickly shattered and become useless. v To avoid this, the handles have been covered at their upper ends with leather'. ln use, however, the leather is soon torn to shreds and the han-r dle is then exposed directly to the blows of the hammer and is quickly splintered.

These tools are very expensive and their destruction after comparatively short usage becomes quite an item to wood workers. It is accordingly an obje-ct of my invention to provide a tool handle which will stand up under the hardest usage 'and to this end I `have devised the handle hereinafter described.

In the accompanying drawings:

Figure 1 is a side elevation ofA a chisel, showing the handle in longitudinal section.

Fig. 2 is a side view of the chisel at right angles to Fig. l; and

Fig. 3 is a cross section thereof, taken on line 3-3 of Fig. 1, and looking in the directicnof the arrows.

Referring to the drawing more in detail the numeral 1 designates the tool as a whole, which is provided with the metallic cutting portionv 2 and wooden handle 3, the latter being mounted on the chisel proper in the usual manner.

The upper end of the handle is provided with an elongated opening 4 which is slightly larger in diameter than the screw 5,`but not quite so long. It should'be noted that the screw is somewhat blunton its lower end for a purpose to be later described. The upper end of the opening' is provided with a counter-sunk port-ion 6, either squared or tapered, to receive the head of the screw.

In assembling the device, the opening 4 is first filled with a cement 7, such as glue or other similar material. The screw is then inserted in the opening before the cement has had. time to set and is screwed into place,

thereby embedding the blunt, slightly tapered end in the wood of the handle, and seating the head of the screw in the countersunk portion. Y

When in use the head of the screw receives the impact of the blow from the hammer and transmits it throughout the handle. In this manner the blow is not concentrated at any particular pointon the handle and the latter is accordingly much more durable. B v using a screw vwith a blunt end the same is prevented from unduly working its way into the handle.

In the claims appended hereto the wordl 8 cement is intended to include all compositions having the inherent properties of cements or similarfmaterials.

Having fully described my invention, what I 'claim as new and desire to secure by Letters Patent is:

l. A handle for chisels and thev like, pro-- vided with an elongated opening in one end thereof, a screw inr said opening to receive the blow of a hammer, said screw being of less diameter `than the opening, and wood 'adhering cement filling the space between the screw and the walls of the opening.

2. A handle for chisels and the like, provided with an elongated opening in one end thereof, means in said opening .to receive the blow of a hammer, said means beingof less diameter than the opening, and vbeing embedded'in wood adhering cement. c

3. A handle for chisels and the like, provided with an elongated opening in one enc thereof, means in said opening to receive the blow of a hammer, said means being of less diameter than the opening and being einhedded in wood adhering cement, said means being of greater length .than the opening and having its lower end embedded in the nia-- teria] of the handle.

4. A handle for chisels and the like, pro-r vided with an elongated opening in lone end thereof, a screw in said opening to receive the blow ofa hammer, said screw being of less` diameter than the opening, and having its lower end embedded in the material of the handle.

5.V A handle for chisels and the like, provided with an elongated opening in one end thereof, a screw in said opening to receive the blow of a hammer, said screw being of less diameter than the opening, and having its lower end embedded in the material of the handle, and wood adhering cement or the like filling the space between the screw and the Wall of the opening.
