IMPROVEMENT IN HAMMERS.

Specification forming part of Letters Patent N0. 149,912, (lated April 2l, 1874; application liled February 14, i874.

To all whom 'it may concern:

Be it known that I, OANninUs BILH/inz, of Pittsylvania Gourt-House, in the county of Pittsylvania and State of Virginia, have invented a new and useful Improvement in I-Iammers, of which the following is a specitication:

The invention will rst be -fully described, and then pointed out in the claim.

In the accompanyn g drawing, Figure lis a side view of the hammer, partly in section. Fig. 2 is a view looking from the line a; a' of Fig. 1.V

Similar letters of reference indicate corre- A is the hammer. I3 is the handle thereof. C is the main claw for drawing nails. Dis the claw for drawing tacksformed of one side of the main claw. E is apoint formed by eX- tending the other part 0i' the main claw, as seen in the drawing. This point is for the purpose of enabling` the operator 'to make a hole in the wood, in which the nail will stick without holding previous to driving. At the base of the claws an orifice, F, is made through the hammer, in which I attach, by a pivot-pin, an eccentric jaw, Gr. This jaw works in connection with the forward end H of the orifice F, and is pressed toward the end H by the spring I. This jaw is notched or serrated to prevent slipping` from the nail.

The object of this arrangement is to draw nails which have no heads, such as the main claw C will not take hold of. When the end of such a nail is once made to enter the orice F between the serrated end of the jaw G and the end H of the oriiice F, it is tightly held, and the nail may be drawn by the usual movement of the hammer.

This eccentric jaw and orice'may be applied to any hammer or instrument for drawing nails or spikes. The improvement, therefore, is not intended exclusively for application to nails without heads, but will gripe and hold anything that can be introduced, the jaw and oriice being properly proportioned for the use` intended.

In drawing nails with a hammer having a main claw, C, the head of the nail is frequently pulled oli', which renders the hammer useless for further operation; but by means of the orifice F and eccentric jaw G the difficulty is at once overcome.

Having thus described my invention, I claim as new and desire to secure by Letters Patentv The claw-hammer A, provided with jaw G, pivoted eccentrically in and pressed toward the forward end H of the orice F, as and for the purpose specified.

GANDIDUS BILHARZ.
