H A M M E R SPECIFICATION forming part of Letters Patent No. 404,388, dated June 4, 1889.

Application filed Tune 8, 1888. Serial No. 276,466. (No model.)

To all whom it may concern.-

Be it known that I, AMBROSE L. DE VOL, a citizen of the United States, residing at the city of Binghamton, in the county of Broome and State of New York, have invented certain new and useful Improvements in Hammers; and I do declare the following to be 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-accompany: ing drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

Figure 1 is a longitudinal section of the hammer; Fig. 2, a plan view of the guideplate straightened out; Fig. 3, a side view of the guide-plate finished. Fig. 4 is an inside view of the hammer head. Fig. 5 is an end view in the direction of the arrow; Fig. (5, a section 011 line y y; Fig. 7, a section on line as a; Fig. 8, a section on line .2

This invention relates to a magazine-hammer wherein are held the tacks or small nails ready for use, whereby is obviated'the necessity of using both hands in tacking.

The invention consists in the construction hereinafter set forth.

In the annexed drawings, the letter A indicates the handle, which is round and hollow, preferably tapering, as shown, and open at both ends. The larger end a is covered by a cap B, threaded or otherwise secured thereto. The smaller end a is filled by a plug C. This plug fills the end a of the handle and has at its larger end the under-cut c.

Secured on the head a of the handle A is the head 'D. The driving end at is made as usual. The peen end (1 has on the rear side the g'toove (Z O11 the under side of the bore the head has the wings 6 Q, extending rearward, with the upper end of the groove (Z between them. The groove (1 then slants forward, having the oblique portion (Z and then downward, having the vertical portion (1, and at the eXtremity e of the peen runs out, as shown. The rear edge 9 of this peen end is'curved, as shown.

In Fig. 2 is shown the guide-plate F. As shown in this figure, it is of flat sheet metal possessing more orless elasticity. At one end it has a tang f and shoulders f f. In it is made a slotf, at one end of which 1s the circular hole f and at the otherend the crossslot f forming the recesses or offsets f The main part f of this guide has the width of the peen end of the hammer-head. This guide is placed over this end, as shown in Fig. l. The tang f is put through the bore 6,

the end f being turned down and the shoul- 6o and the upper end of the groove (Z being in This guide F fits line, as shown in Fig. 1. snugly against the outside faces of the wings e e of the head, the slot f being above the groove (Z The other end of the guide is turned around the extremity c of the head 76 and is turned up, as shown at f the slot f coming so as to have its bottom a little below the face of the extremity e of the head. This guide is made so that the transverse diameter of thehole f and the length of the cross-slot f are about the same as the width of the groove 61 or at least sufficient to pass the head of a tack, as will be explained. The slot f is smaller than the width of the groove (F, or

sufficient to accommodate the stem of a tack. 80

On the under side the handle A has a slot a, about the width of the slot f and running from the head D back a suitable distance.

In use the magazine or hollow of the handle is supplied with a due number of tacks. 8 5

A vigorous shake causes some of them to settle with their stems projecting through the slot a, the heads keeping them from dropping through. By shaking the hammer with the head slightly held down the tacks will slide toward the head. As they come to the hole f and the wings e, the tacks are given a downward turn, the heads slipping through the hole f and into the groove (1 the stems protruding through the slot f ing down push one another until one passes around the curved edge of the peen to the end 6 of the hammer and is ready for insertion, when a slight blow causes the tack to stick.

The hammer is then withdrawn backward, [00

the slot f slipping over the head of the tack. The hammer-head is removed and the tack The tacks passdri\'en home. The operation is continued until all the tacks are exl1ansted,when the magazine is refilled.

I am aware that a hammer has had a magazine attached to it and that hammers have had hollow handles as a receptacle for tacks; but the tacks are not fed to the head, as in my invention. By myinvention I have a hamnier complete in itself without any auxiliary device, the hammer containing Within itself the magazine from which the tacks are automatically fed to the head.

\Vhat I claim is- 1. A hammer having the handle A made hollow and provided with a slot 1v underneath, the head I), having the driving end I] and the poem end (1, the latter having a groove (I? in its rear side connecting with the slot o said groove being covered by a slotted. guide-plate which extends around the extremity of the peen end of the hammer, as set forth.

2. The combination of a hollow handle having the guide-slot C0, the head D, having the groove (Z and the guide-plate Ii, having the hole f, the slot f and the slot f", as set forth.

In testimony whereof I ailix my signature in presence of two witnesses.

AMBROSE Ii. DE VOL.
