INVENTOR ITNESS W J: A 51427052. QLV 4 BY A ORNE S UNITED STATES JOSEPH A. BARTOSZ, OF SALEM, OREGON.

HAMMER.

Application filed October 4, 1919.

To all w 710m it may concern Be it known that I, JosnrI-I A. BARTOSZ, a citizen of the United States, residing at Salem, in the county of Marion and State of Oregon, have invented a new and useful Hammer, of which the following is a specification.

My invention relates to improvements in hammers, particularly of the claw hammer variety, in which a T-shaped post can be made to appear out of the top of the hammer.

To draw long nails straight and easy out of a board, requires usually the aid of a block under the claw; the object of my invention is to provide for the hammer an adjustable fulcrum which makes the use of blocks unnecessary; another object is to furnish a clamping device whereby a carpenter can drive a nail as high as his hammer will reach, though that point may be beyond the reach of his hand.

Sundry further objects and advantages will appear as the description proceeds.

I attain these objects with the mechanism illustrated in the accompanying drawing in which Fig. I hammer,

throughout the several views.

The post 1 carries at the upper end the cross piece 2, while the lower end 3 is threaded, giving this element a somewhat.

T-shaped appearance. This post is inserted into the claw hammer 4, which latter is provided with the necessary slots for that purpose. Screwable adjustment of the post is accomplished by a knurled nut 5 on the threaded portion 3; said knurled nut being located in a slot 6 of the wall which forms the eye of the, hammer.

mer, is merely a box-shaped cover to protect the threaded portion 3 from damage.

To draw a long nail with this hammer, the knurled nut is turned with the thumb until the, post projects sufficiently for that purpose, as for instance shown in dotted lines in Fig. I, then the claw is inserted under the nails head and the latter pulled, whereupon the post may be returned to its normal place.

It sometimes happens that a place where a nail needs to be driven, is still within the reach of the hammer, but too high for a hand to hold the nail. In such cases the post 1 is raised and the nail is inserted into the slot vacated by the cross piece, so that the head of the nail rests against the post; the cross piece is then slightly clamped down on the head, and the nail tacked into its proper place in the board sufliciently hard to enable a withdrawal of the hammer without pulling the nail again. Further driving of the nail may thereupon be done in the regular way.

Having thus described my invention it will be seen that my objects have been accomplished and, though I have shown the preferred form of construction, I reserve to myself the right to make changes in minor details, providing I do not violate the spirit and principle of my invention.

I claim:

A claw hammer comprising a head, a removable handle in the head, and a groove extending across the upper surface of the head in close proximity to the claw, with a T-shaped post screwably mounted in the head, said post moving at right angles to the groove, and the cross-bar on top of the post coacting with the groove in holding the head of a nail while said nail is being tacked into place.

Signed by me at Portland, Oregon, this 29th day of September, 1919.
