DETACHABLE HAMMER TIP Filed April 25, 1947 INVENTOR.

Q2116 a. my BY W ff f ATTORNEYS.

Patented Mar. 7, 1950 UNITED STATES ATENT OFFICE 1 Claim.

This invention relates to detachable hammer tips and the principal object of the invention resides in the provision of a new and improved detachable soft tip or head for a hammer and including new and improved means for securing the same to the striking element of a conventional hammer.

Further objects of the invention reside in the provision of a relatively soft striking element in the form of a shouldered core surrounded by a ring which has an inwardly directed flange cooperating with the shoulder to hold the core in position on a conventional hammer head, said ring providing means for securing the device to the conventional hammer by means of a coil spring or other resilient means in the form of a loop, the latter being disposed about the hammer handle adjacent the point of juncture thereof with the hammer head so that the detachable device cannot accidentally fall from the hammer or become displaced.

A still further object of the invention resides in the provision of a device as above described and including an outwardly flaring flange at the end of the ring opposite the interior above described, said exterior flange having a pair of diametrically opposed holes therein to receive the hooked ends of a coil spring or the like; and in which the ring may be indented so as to permanently secure the soft core therein, it being pointed out, as an alternative, that without some means to permanently secure the core to the ring, the core may be detached and the operator may substitute therefor cores of different natures such as copper, rubber, plastic, and leather.

Other objects and advantages of the invention will appear hereinafter.

Reference is to be had to the accompanying drawings in which Fig. 1 is a View in side elevation of the hammer attachment in position on the hammer, parts being in section;

Fig. 2 is a view in side elevation of the attachment; and

Fig. 3 is a top plan view of the device.

A conventional hammer head Ill is shown in Fig. 1, this hammer having a striking element of conventional design indicated at [2 and a handle or the like M, as is usual.

The present invention provides a soft striking element indicated at 6 and having an outwardly extending solid flange l8 for disposition behind an inturned flange 20 of a steel ring or the like 22.

The element l6 may be referred to as a core and it will be seen that it may be easily detached from the ring 22 and substitution of cores of different materials may easily be made. At the same time, however, the striking head l2 of the conventional hammer will maintain the core in striking position as long as the device is attached to the hammer.

The ring 22 is made preferably to fairly closely fit the periphery of the hammer head [2 and at its end opposite flange 20 it is provided with a curved outwardly flaring flange or rim 24 which is perforated at diametrically opposite points for the reception of hooks 26 at each end of a coil spring 28 so that the latter is permanently secured to the ring 22.

In order to attach the device to the hammer [0, the handle [4 of the hammer is entered into the loop formed by the coil spring and the device is slid up to the head it! whereupon it is pulled as to the right in Fig. 1, striking the spring, and attached so as to engage at the under side of the hammer head l2 whereupon a slight tilting motion will dispose the ring about the hammer head I 2 in the position shown in Fig. 1.

The spring 28 may be made of such a tension that it will hold the device securely to the hammer head in the position shown and at the same time, the flange 24 prevents contact of the spring with the lateral side surfaces of the hammer head Ill so that there will be no interference between these elements.

If desired the ring 22 may be indented as at 30 to be pressed onto the material of the soft core in the flange l8 thereof so as to permanently connect the core to the ring.

Reference is made to my co-pending application Serial No. 728,161, filed February 12, 1947, the present case providing an improvement thereover.

Having thus described my invention and the advantages thereof, I do not wish to be limited to the details herein disclosed otherwise than as set forth in the claim, but what I claim is:

A device of the class described comprising a cylindrical ring, an inwardly directed flange at one end thereof, an outwardly directed flange at the other end thereof, a soft one piece core in the ring, said core having a portion of a diameter to extend through the inwardly directed flange of the ring outwardly thereof, and a portion of larger diameter abutting the inwardly directed flange and held against escape from the ring in the direction that the smaller diameter soft core portion extends from the ring, a spring attached to the ring at substantially diametrically opposite points of the outwardly directed flange to fit over a hammer head from one side surface thereof to the other side surface of the hammer head and keep the latter in abutting relation with the soft core to maintain the soft core REFERENCES CITED against the inwardly 'directed flange, the core being otherwise free of the ring and easily reg f rtiferences are of record m the moved and replaced, and said spring being 6 o 8 en adapted to fit over the hammer head with por- 5 UNITED STATES PATENTS tions of said spring extending over the opposite Number Name Date side surfaces of said hammer head to retain the 378 632 svensson Feb 28 1888 device thereon the use Of the hanlm r- Peters t CARL UIFVES- 1,792,153 Evich Feb. 10, 1931
