Specification of Letters Patent.

Patented July 8, 1919.

Application filed July 31, 1916, Serial No. 112,356. Renewed March 31, 1919. Serial No. 286,551.

i a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to the class of wood working tools, and has particular reference to an imporved hammer or hatchet construc- I tion.

My invention has for its primary object to provide a hammer or hatchet which possesses greater strength for all useful purposes to which it may be put than those like devices which are known to me. Where the average hatchet is used for pulling out a bent or misplaced nail, the whole strain of the pull comes on the point in the handle just back of the socket into which the handle fits so that when any undue force is used in pulling a nail the handle is often broken. Nearly every hatchet must be skilfully handled in order to prevent the handle from breaking, regardless of the quality of the material or the initial strength of the handle. By my improved construction, the handle is relieved of the greater part of this strain without adding materially to the weight of the device or to its bulk.

My invention also contemplates an improved hatchet or hammer construction, in which it is practically impossible for the head to fly off the handle.

It is also an obj set to construct a hammer or hatchet which is in the nature of a combination tool, the usual head construction having combined therewith a movable part which may be actuated as a wrench element for use in removing burs and similar at tachments.

lVith the above and other objects in view, as will hereinafter appear, my invention will now be fully set forth and described, reference being had to the accompanying drawings, in which Figure 1 is a side elevation of the device,

Fig. 2 is an elevation of the handle meme Fig. 3 is a plan View, and

Fig. 4 is a section on line 4-4 of Fig. 1, looking in the direction the arrow.-

ln said drawings, in which the hatchet enibodying my improvements is shown, 1 indicates the body of the hatchet having the usual hammer head 2, and the handle socket 3. The handle 4 is fitted into the socket 3 in the usual manner, but between the socket 3 and the hand grip portion 5, the handle 1 is reduced to provide the recess 6. The recess 6 constitutes'a seat for a pair of arms 7 which extend re'arwardly from the body 1, at the upper extremity of the socket 3. Said arms 7 lie in parallel relation, and form rearward extensions of the Walls of the socket .3, and are of such cross-sectional dimensions that their upper faces merge into the upper face 8 of the hand grip section of the handle. Thus, the rear ends of the extension butt against the face 9, and the lower sides thereof rest upon the bottom of the recess 6 throughout their lengths. At their rear ends, the arms 7 are joined by a U-shaped yoke 10 which extends around and closely ts the sides and bottom of the handle a, so that the arms 7 are closely confined within the recess 6, and any tendency of the arms to spring is avoided. A rivet or bolt 11 is passed through the handle 4: and through the sides of the yoke 10, so that the elements are thus further securely united. It will be noted that the rivet 11 not only acts to unite the arms and the yoke to the handle at but also serves to retain the hatchet head upon the handle. It is thus practically impossible for the head to fiy off the handle.

The rear side of the hammer head 2 is cut away to provide a recess 12, in which is seated a block 13. Extending through the body of the hammer head 2, and having the head 13 rigidly mounted thereupon is a bolt or shank 14, which extends rearwardly from the hammer head 2 and is provided with a foot 15 Whose lower extremity rides upon the bottom of the recess 6, between the arms 7 the shank 1 1 constituting a carrier for the block 13 which forms one member of what is in effect a separable tool head. That portion of the bolt or shank 14 which extends through the hammer head 2 is squared, so that as the bolt is reciprocated through said hammer head, the block 13 will be held in upright relation, in opposition to the body of the head 2. The exposed portion of the bolt is threaded and carries the nut 16, which upon rotation, frees the bolt 14, so that the block 13 may be spaced from the body of the hammer head. 21; In this manner, the

block 13 and the head 2 constitute the opposing jaws of a wrench, the proper rigidity for the wrench structure being secured through the connection between the foot 15 and the arms 7 and the sliding relation of the squared portion of the bolt 1% with the head 2.

From the foregoing description it is evident that my improved construction may, with equal facility, be applied to a hammer structure instead of a hatchet and that all of the advantages hereinabove claimed for the hatchet construction will also be secured for the hammer structure.

The construction defined provides a hatchet 0r hammer which possesses agreatly increased amount of strength without an undue increase in weight or bulkiness, and, furthermore provides a combination tool which greatly adds to the convenience and utility oflthe device.

relation therefrom against said flattened portion of the handle and having a yoke connecting the extremities of the arms and embracing the handle, and a carrier for the second head member slidably engaged with the socketed head member, with its extremity slidably held between, said arms.

In testimony whereof, I affix my signature,

inthe presenceof two witnesses.
