COPPER-TIPPED HAMMER.-

$PECIPICATION forming part of Letters Patent No. 334,283, dated January 12, 1886.

Application filed September 30, 1885. Serial No.178,623. (N model.)

To all whom it may concern:

Be it known that I, HARRY A. RANDALL, a citizen of the United States,'residing at Terryville, in the county of Litchfield and State of Connecticut, have invented certain new and useful Improvements in Copper-Tipped Hammers, of which the following is a specification. I

My invention relates to improvements in hammers for striking finished work without marring it; and the objects of my improvement are to provide copper-tipped hammers with a cheap and convenient means for securing the tips and for removing them when desired, and also to so arrange the tips that they may be partially rotated within their sockets for securing them in different positions.

In the accompanying drawings, Figure 1 is an elevation of one side of my hammer, and Fig. 2 is a sectional view of the same on line a; m of Fig. 1, but partly in elevation.

A designates the hammer-head, which I prefer to make of cast metal; but it may be forged, if desired. The ends of this head .I provide each with asocket and with a transverse slot, (2, which opens into the inner end of the socket. The side wall of each socket is provided with a threaded hole to receive the set-screw b.

B designates copper tips, the shanks c of which are placed within the respective sockets, and the tips are secured by the set-screw b.

I prefer to form an annular groove, d, in the shank 0, into which groove the end of the set-screw enters, as shown. The shank 0 is long enough so that its inner end projects slightly into the transverse slot to.

The copper tips enable the hammer to be used for striking finished work without marring it.

In case one corner of the tip becomes battered more than the other, the set-screw may be loosened and the tip partially rotated on its axis, so as to bring the battered portion into some other position relatively to the hammer-handle, and then the set-screw can be tightened to hold the tip in place.

When the tips are worn out and new ones are to be substituted, or when for any reason it is desired to remove them, the set-screw is loosened far enough to withdraw its end from the groove, and in case the shank sticks in its socket a suitable keyor tapering wedge-as, for instance, a file-shankmay be forced into the slot a against the end of the shank c, for starting the shank and tip out of the socket.

I am aware that prior patents show hammers or mallets having soft-metal heads; also, that prior patents show and describe hatchets having a socket at one end, into which metal tips are secured-in one case by friction only, and in another by a rivet or screw passed through the walls of the socket and shank of the tip. Another patent shows and describes a hammer-like head having a dovetail slot through each end, into which tips of various forms having dovetailed shanks are placed, and made fast by rivets or screws which pass through the walls of the dovetailed slot and the dovetailed shank of the tip. All of said prior art is hereby disclaimed.

I claim as my invention 7 The herein-described hammer, consisting of the head A, having tip-receiving sockets and transverse slots connected therewith, the setscrews 1), and the tips B B, having shank a, secured within the socket by means of the setscrew, substantially as described, and for the purpose specified.
