HAMMER.

SPECIFICATION forming part of Letters Patent No. 613,459, dated November 1, 1898.

Application tiled December 22,1896. Serial No. 616,677. (No model.)

To all whom it may concern.-

Be it known that I, EDWARD G. MINNE- MEYER, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Hammers; and I do hereby declare the following to be 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.

Figure 1 is a side elevation, partly in section, of the head of my improvedhammer. Fig. 2 is a view of the handle detached. Fig. 3 shows the completed article. Fig. 4. is a sectional view showing in detail the Vmanner of securing the handle and head together. Fig. 5 is a similar view showing a slightlymodiiied construction. Fig. 6 is a view of a slightly-modified manner of securing the handle shown in Fig. 2 to the head.

In the drawings, A designates the hammerhead, which may be of any suitable size and form, and B designates the handle.

As shown, the handle B is formed from a single metallic Yrod which is iirst bent upon itself to form the loop() and then has the members thereof twisted together from a point adjacent to said loop to a point near the endsl of the rod. The ends of the handle-rod are inserted into suitable passages a, formed in the head A, and are held therein by means of the above-described twist and by a rivetpin D. The latter is passed through a passage a', formed in the head substantially at right angles to the passages a, and engages with notches or recesses b', formed in the members b of the handle. Preferably the ends of the members b are inserted in the sockets or passages provided therefor in the head prior to twisting said sections together, such twisting acting to clamp said sections or members still more closely on the rivet-pin D. As an additional means of securing the handle and head together the ends of the members h may extend entirely through the head and be upset or formed into enlargements b2, as shown in Fig. 3, which will assist in preventing separation of the handle and head; but in many cases the pin D, en-

gaging with the head and entering the notches or recesses in the members b of the handle, will be a sufficient fastening, and therefore the ends of said members b need not extend through the head, but merely into sockets formed therein, as indicated in Fig. 5.

Instead of employing a single lock-pin, as above described, when both ends of the handle-rod are inserted in the hammer-head I may employ two of such pins, one for each end of the handle-rod, as shown in Fig. 6.

While I have herein shown my improvements as applied to light hammers, I do not wish to limit myself to such a tool, as I am aware that my improvements are applicable to hammers of various forms, hatchets, dac.

The present implement is characterized by having the pin fastening for the head and the supplemental fastening and bracing provided by the twisting of the wires or bars of the handle. The twisting of the latter parts is eected in such way that the last coil or turn adjacent to the head exerts a powerful pressure, the result of which is that the head is bound between-the twists of the handle and the transverse pin, the tension resulting from the twists in the handle preventing loosening of the head or the pin, and by having this force exerted upon the head by the twists the handle immediately adjacent to the head is stiffened and vibrations are prevented. This is true not only of the construction shown in Fig. l, but also of that shown in Fig. 6, in which the pressure of the coils against the head acts to brace the parts and hold the head and pin properly together.

What I claim is-- In a hammer, the combination of a head having two passages or sockets, a, formed therein, and a third passage, a', extending at an angle to and communicating with both the first vsaid passages, a handle formed from a single metallic rod having its ends inserted in the passages or sockets, o., and its intermediate portions twisted together, and a lockpin extending through the passage, a', in the head, between and contacting with both members of the handle, substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses.

EDWARD G. MINNEMEYER.
