1 Claim.

This invention relates to a hammer for all purpose use.

The chief object of the present invention is to provide a hammer that can be constructed on a mass production basis and economically and finished to specific uses, the finishing requiring a minimum of parts and these of simple construction.

The chief feature of the present invention resides in providing a hammer body of suitable material and apertured for handle reception, said body having integral threaded extensions for attachment to thread socketed caps or heads.

Another feature of the present invention resides in providing a handle-body lock that cannot become loose as is`the case with conventional handle wedges and which lock is most desirable for heavy duty hammers.

The heads, disposed at opposite ends of the body, may be alike as to material or shape or may differ. Such material may be aluminum, brass, copper, steel or lead metal, or plastic or bre, or rubber or rubber-like material, or even wood or rawhide.

In general the head is cylindrical in shape so that it readily lends itself to production from bar stock if of wood or harder metals such as steel, brass, etc.

Other objects and features of the invention will be set forth more fully hereinafter.

The full nature of the invention will be understood from the accompanying drawings and the following description and claim:

In the drawings:

Fig. 1 is a perspective view of a hammer embodying the present invention.

Fig. 2 is a central sectional view of the same.

Fig. 3 is a top plan View thereof with the upper head removed.

In the drawings I0 indicates a conventional wooden handle that drive seats into a transversely and centrally disposed bore I I in an elongated cylindrical body I2. 'Ihe bore is flared Ias at I3.

The body at opposite ends includes integral threaded extensions I4 which are axially aligned. The resulting structure may be formed from cylindrical bar stock in an automatic machine, etc., thus lending itself to rapid and economical production with the loss of but that part necessary to form the extensions and the bore, the latter being formed by broaching or multiple drilling and the like.

The heads also may be expeditiously and economically formed on automatic screw machines and from bar stock. Each head is herein shown as a cylindrical body I5 having centrally thereof a bore I6 internally threaded at II, the mouth of the bore being chamfered as at I8.

The bore opens upon flat face I9 and is adapted to bear upon fiat face 20 at the end of the body I2. The chamfer I8 accommodates such portion (root) of threaded extension I4 as may not be threaded. Thus the actual bearing between body and head is truly annular, as it were, thus reducing the unit shock or load to be transmitted from the head to body and vi-ce versa and also relieving the extension I4 of the same for it thus serves chiefly as a connector because it terminates short of the inner end of threaded bore I6.

Mass production of heads and bodies thus can be effected and from desired materials for it is obvious that any body can accommodate any two different kinds of heads. Also when a head becomes worn it can be readily removed and redressed or a new head substituted as desired.

Reference will now be had more particularly to Figs. 2 and 3. Therein the body is shown provided with a bore 2I parallel to the extension axis and sufficiently offset radially therefrom. This bore is so disposed that it intersects transverse or handle bore II. Bore 2| extends from one face 20 toward the opposite face and may extend to the Same or terminate short of the latter, as illustrated in Fig. 2.

The mouth of bore 2I is counterbored as at 22. After handle I0 has been drive seated in bore I I a nail 23 is. seated in bore 2| and driven through the handle, the head 24 of the nail nesting well within the counter bore 22 so as not to project beyond the face 2U. Thus facial contact between body and head is assured at all times. Obviously application of the head I5 retains the nail against loss if the same ever became somewhat loose in the handle. The nail when driven home obviously forms its own hole through the handle.

While the invention has been illustrated and described in great detail in the drawings and foregoing description, the same is to be considered as illustrative and not restrictive in character.

The several modifications described herein as well as others which will readily suggest themselves to persons skilled in this art, all are considered to be within the broad scope of the invention, reference being had to the appended claim.

The invention claimed is:

In a hammer, a generally cylindrical body of substantially uniform diameter throughout its length and having at faces at both ends disposed at true right angles to the axis of said body, threaded extensions integral with said body and projecting axially therefrom at each of said body ends, detachable heads for each of said extensions, each of said heads having an interiorly threaded centrally disposed socket to be engaged With the threads of said extensions in face to face Contact with the respective faces of said body, said body having a transversely disposed handle receving opening in its midportion and a longitudinally disposed bore extending from one end adjacent the other end thereof.

through said opening and offset. laterally of said extensions, and a safety pin freely receivable in said bore to extend through a handle received in said opening and sealed therein by said detachable heads.
