NAIL HAMMER. No. 378,650. Patented Feb. 28, 1888;

Inv ardor DAVID PHILANDER BIGAELOV, OF ARLVILLE, IOVA.

SPECIFICATIONforming part of Letters Patent No. 378,650, dated February 28, 1888.

Application filed June i8, 1887.

I0 @ZZ whom it may concern.-

Be it known that I, DAVID PHILANDER Bref- ELOW, a citizen of the United States, residing at Earlville, in the county of Delaware and State of Iowa, have invented certain new and useful Improvements in Nail-Hammers, and I do declare the following to he a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon,which form a part of this specification.

Thespecial object ofthe invention is to make a hammer adapted to drive large orsmall nails without slipping thereon; also, to do blind-nailing; also, to prevent the hammer'handle from working loose in the head or being slivered; also, to render end of hammer perfectly tight in the head.

Figure l of the drawings is a longitudinal section showing the handle, head, and auxiliary parts put together; Fig. 2, a detail view, in side elevation, of the handle; Fig. 3, a perspective view of the top strap 5 Fig. 4, a similar view of the bottom strap; Fig. 5, a similar view of the tightening-wedge.

In the drawings, A represents the handle having the rabhets a a on opposite sides, the shoulders a a', and the open end slots, a2 a2.

B is the upper fastening-strap, and C the lower one, both made of metal and each hav ing a front shoulder. These front shoulders, Z) c, rest in the front notches, d d', of the hammer D.

On the top strap, B, there is no rear shoulder 5 but on the bottom one7 C, is the rear shoul- Serial No. 241,763. (No model.)

der, c2, which fits in the rear notch, d2, ot' the hammer-head.

The wedge E is made with the side shoulders, c, so that when driven into the handle slots aKZ the wood that has been pressed out laterally will spring back over the shoulders e and effectually prevent the wedge from beingjarred out.

In practice I fit the bottom strap, C, into the head with its shoulder' c in the notch d and the shoulder c in the notch d2, then put the handle in, and drive the top strap into the head until the shoulder b enters the hemmen notch d. Finally, I drive the wedges E horne7 into the open slots a2, when the hammer is com plete and ready for use.

I make the hammer-head to weigh from one and one-half to two pounds, and make the workingface d3 perfectly flat, so that it will not slip on a nail.

Having thus described all that is necessary to a full understanding of my invention, what I claim as new, and desire to protect by Letters Patent, is

The combination of a wooden handle having open end slots, a2, metallic straps B C, having shoulders b c ci, a hammer head having the notches d d di, and the wedges E E, having shoulders e @,wherehy the shoulders I) c c2 may be forced into and held in the notches d d di, as described.

In testimony whereof I affix my signature in presence of two Witnesses.

DAVID PllTTulNIlllR BIGEIADW.
