2 Claims.

.My invention relates to hammers and relates more particularly to improved means for attaching hammer heads to the handles therefore.

My invention further contemplates the use of such improved means for attaching handles to other hand tools than hammers, such as axes, adzes or the like.

Hand tools, such as hammers, of the prior art are ordinarily provided with metal wedges to secure the heads to the handles of such tools. In use, such Wedges often fall out or are ejected because the handle is weakened by dampness and the wedges are often forced out by the constant pounding or other use of the tool.

It is an object of my invention therefore initially to provide an improved hammer.

It is a further object of my invention to provide improved attachment means for securing such hammer head and its handle portion together.

A further object of my invention is to provide means for securely fastening a hammer head to the handle therefor and preventing the same from becoming loose after successive pounding on the same or after the exposure of the hammer to moisture.

A still further object of my invention is to provide improved means for securing a handle to a tool of the general type described which will remain secure and prevent the head from flying ofi thus achieving a safety quality in hand tools.

A further object of my invention is to provide means for dampening 0r cushioning the handle against the force of blows upon the hammer head.

A still further object of my invention is to provide a hammer or the like which will be inexpensive to manufacture, composed of but few parts and highly efficient and durable in use.

Other objects of my invention and the invention itself will become more readily apparent from a purview of the description and the ap-- pended drawings.

In the drawings:

Fig. 1 is a view partly in section and partly in elevation of a hammer which is an embodiment of the handle of my invention;

Fig. 2 is a view partly in section of the hammer head of Fig. 1;

Fig. 3 is an exploded view of the improved handle portion of my invention;

Fig. 4 is a perspective view of the attachment means of Fig. 1 which assists in joining the head of Fig. 2 to the handle of Fig. 3.

Referring now to the drawings, in all of which like parts are designated by like reference char- 2 acters,in Figs. 1 to 4 inclusive I show my invention as applied to a hammer. In Fig. l, I show a hammer 10 of the familiar claw-type having a head portion l preferably of metallic material having a handle 2 of wood or other preferred material.

The hammer head I is formed with the usual socket portion 3; said socket portion, being generally U-shaped in cross-section, is further provided adjacent a centrally disposed portion thereof, as best shown in Figs. 1 and 2, with a tapered groove 4. Said groove 4 is preferably formed with a substantially flat inner face 5 and a pair of oppositely tapered sides 6 and l, wherefore the groove is of substantially greater width adjacent the inner face of the socket and of substantially less width at its most inwardly formed portions 5.

A horizontally extending bore 8 is disposed laterally at the one side of the handle receiving socket portion of the hammer communicating with the generally tapered U-shaped groove 4 on the inner face of the socket, said bore extending from the groove to the exteriorly disposed outer surface of the socket portion. A mating complementary groove 9 is formed on the outer surface of the upper portion [4 of a preferably wooden hammer handle 2. When the handle 2 is press fitted within the socket in the hammer head I. the groove in the handle mates with the groove within the handle socket to form a generally sixsided channel or conduit adapted to receive rubber or plastic material which is injected therein in fluent form under pressure through the aperture or bore 8 which communicates with said channel. At [5 I show a pressure relief opening. The upper portion of the handle is preferably tapered as shown at 20.

The said rubber or other plastic material is allowed to solidify in the channel or conduit and plugs or the like may be inserted within the bore 8, if desired, to seal the fluent rubber or other material therein, until solidification occurs. Upon solidification, the substantially annular core [3 which has been formed exerts pressure against all sides of the channel and securely connects the handle and hammer head together. When rubber or other flexible material is used to unite the tool head and handle, as above described, the tool not only has an expansive force which tends to more securely retain the handle within the socket of the tool, thus preventing loosening because of pounding or impact force on the peen end of the hammer, but also provides '2 a a dampening member which absorbs some of the force of the blow imparted to the tool.

Although I have described my invention in connection with a preferred embodiment, it will be understood that numerous and extensive departures may be made therefrom, such as forming the head of the tool, which may be of various sorts, and any handle therefor of diiferent materials, and inserting various fluent material in conduits similantodhatinsed inthissembodiinenm. without however departing fromthe spirit of my invention and the scope of the appended claims.

What I claim is:
