MAGAZINE TACK-HAMMER.

SPECIFICATION forming part of Letters Patent No. 630,116, dated August 1, 1899. Application filed January 12, 1899. Serial No. 701,952. (No model.)

To all whom it may concern.-

Be it known that I, Lnwrs W. SAMMIS, of the city of New York,(Greenpoint,) borough of Brooklyn, in the countyof Kings and State of New York, have invented a new and Improved Magazine Tack-Hammer, of which the following is a full, clear, and exact description.

My invention relates to an improvement in magazine tack-hammers; and it consists of IO means for more securely holding the tack in place ready for driving and for preventing tacks from being accidentally discharged while in use than in hammers of its class as heretofore constructed.

I5 My invention further comprises the novel features hereinafter described and claimed.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indizo cate corresponding parts in all the figures.

Figure 1 is a side view of my device, showing the delivery-chute and a portion of the hammer-head in section. Fig. 2 is an under plan view of the hammer. Fig. 3 is an end View of the hammer-head; and Fig. disa section of the hammer-head, taken upon the line l 4 in Fig. 1.

To the handle A of the hammer is secured a reservoir or magazine 0, which contains the tacks. To the end of the magazine or reservoir which is next to the hammer-head is secured a delivery-chute D, curved in crosssection and havinganarrow opening passing down the center of one side adapted to re- 3 5 ceive the stems of the tacks, the heads being in the meanwhile carried by the under portion of the chute lying at each side of the slot. This chute extends downward to the hammer-face and extends horizontally under the same, terminating a short distance beyond the inner edge of the hammer-face, as clearly shown in Fig. 1. A short section H of the under portion of this chute extends beneath the hammer, and said section and the adjacent ends of the guard-plates E hold the tack in position before driving.

The under surface or face of the hammer is provided with a groove I, (clearly shown in Figs. 3 and 4,) adapted to receive the heads of the tacks. Beneath this portion of the hammer-face lie the guard-plates E,whicl1 are supported upon spring-arms F, the latter extending upward along the side faces of the hammer-head and lying within grooves G, formed therein. These spring-arms,asherein shown, consist of round wires, although the same may be made as flat springs. These spring-arms are securely held in place by means of a bolt J, which passes through the hammer-head and engages both spring-arms. The inner or adjacent edges of the two plates E are sufficiently close together to prevent the tacks from being discharged between them while the hammer is in ordinary use.

The tack is freed from the hammer after being driven into the floor by pulling the hammer bodily away from the tack. The plates E are slightly beveled at their inner corners, which are next to the delivery-chute 4 D, so that they will spread sufficiently to pass the tack and free it. As one tack is driven and removed from the hammer another one comes down into place ready for driving. The opposite face of the hammer may be used for driving the tack home.

One end of the magazine is provided with a hinged door K, which is secured in place by a spring-catch L, so that the door may be opened for filling the magazine with tacks.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent-- 1. A magazine tack-hammer, having a slot or groove extending centrally across its face and adapted to receive the tack-heads, independent spring-held plates projecting toward each other from the sides of the head over the hammer-face and its groove, their inner edges being normally closely approaching and engaging the tack-stems to prevent their 0 escape, said edges being slightly beveled at the end first engaging the tack, a magazine, and a feeding-chute leading therefrom to the hammer-face and presenting the tacks to the groove in the face, substantially as described. 5

2. A magazine tack-hammer, having a slot or groove extending centrally across its face and adapted to receive the tack-heads, springarms securedto opposite sides of the hammer-head and projecting beneath the ham- I00 mer-face one at each side of the groove, plates tacks to the groove in the face, substantially secured to said arms and projecting toward as described.

each other over the hammer-face and its groove to engage the tack-stems and prevent their further movement along the groove, a magazine and afeeding-chute leading therefrom to the hammer-face and presenting the L. \V. SAMMIS.
