LEON OSMONID BANDELL AND REGINALD HARVEY RAPLY, OF GLENMORE, AUCKLAND,

- NEW ZEALAIN'ID.

CLAW-HAMMER HEAD.

Application filed June 9,

To all whom it may concern:

Be it known that we, LEON OsMoND RAN- DELL and REGINALD HARVEY RArLY, sub jects of the King of Great Britain, residing at 37 Aitken Terrace, Glemnore, Auckland, in the Dominion of New Zealand, have invented new and useful Improvements in Claw-Hammer Heads, of which the following is a specification.

This invention relates to the well known type of claw hammer used by carpenters and others. These hammers as generally made hitherto, do not allow of the claw being satisfactorily used in the drawing of tacks or small nails, as the claw grip cannot be worked in under the heads thereof owing to its size. These hammer heads also lack lei *erage capacity in the drawing of large nails.

The object of the present invention is to provide a construction of hammer head that will obtain the twofold purpose of making adequate provision for the withdrawal? of small nails and tacks and also of providing a heel or raised fulcrum upon which the hammer may be levered when drawing large nails.

The invention therefore consists in constructing the hammer head with a second and small claw formed by a pair of prongs arranged to project outwards and upwards in a curve from the top of the hammer head at a position to the rear of the main claw and forward of the handle socket. The said prongs extend in the same line as those of the main claw.

This construction is shown in the acoompanying drawings, in which 2-- Figure 1 is a side elevation, and

Figure 2 is a plan of a hammer head made in accordance herewith.

In carrying out the invention, the ham- 1924. Serial No. 718,933.

mer head A is made in the usual manner with its claw members B curving from one end, but is also made with an additional and small claw C positioned between the main claw and the handle socket D, upon the outside surface of the head. This small claw is made by forming two prongs so that the curve outward from the main claw surface and extend in the same direction as the main claw, sufficient pitch or clearance being given such ,prongs to allow for a tack head or small nail head passing in between them and the surface of the main claw. The space between the two prongs is also made of the V shape shown in Figure 2.

These prongs C also serve as a fulcrum upon which the hammer head may be levered when using the large claw in drawing nails, etc., and by reason of the fulcrum being close up to the main claw, a much wider range of leverage is obtained and consequently greater power in the drawing of such nails.

We olai1n:

A claw hammer head provided with a main claw projecting from one end thereof, and also constructed with a smaller and auxiliary claw which projects from the same end and in the same direction as the main claw; said auxiliary claw being located at the base of the main claw but at the opposite side thereof from the handle socket, so that it forms a fulcrum whereon the head directly rocks when the main claw is engaged in extracting a large nail.

In testimony whereof, we afiix our signatures.
