Specification of Letters Patent.

Patented Oct. 23, 1906.

Application filed June 4, 1904. Serial No. 211,108.

To all whom it may concern:

Be it known that I, HENRY CLAY LYON, a citizen of the United States, and a resident of Howard Lake, in the county of Wright and State of Minnesota, have invented a new and Improved Hammer, of which the following'is a full, clear, and exact description.

My invention relates to hammers, and more particularly to those of the magazine type, which carry and supply nails in position for driving.

Its principal objects are to provide a simple and effective device of this class.

It consists in the various features and combinations 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 indicate corresponding parts in all the fig Figure 1 is a side elevation of one embodiment of my invention.

Fig. 2 is an end elevation thereof looking from the left in Fig. 1 and partly broken away and in section. Fig. 3 is a longitudinal section on the line 3 3 of Fig.2, showing the elements in the position Fig. 4 is a similar view, but with the parts in their delivery osition; and Fig. 5 is a detail in perspective 0' the controlling and contact member.

I have here illustrated a hammer comprising, more essentially, a head 10, having a contact-shank 11, claws 12, and a socket 13, by which is carried a handle 14.

Mounted on the outer side of the head, which preferably has such a shape as to substantially conform to it, is a casing C, which may be secured in place by screws 0. In the outer portion of this casing is situated a magazine-chamber '15, having a supply-opening provided with a cover 16 and held normally closed by a spring 17, contacting with an arm 17, projecting from the inner wall of the casing. The magazine-chamber terminates in a throat 1 8, narrowed longitudinally of the hammer and having at its inner end a feed-opening 19. In the lower portion of the casing beyond this feed-opening is formed a channel 20, having lateral curved walls 2 1, converging outwardly to a contracted delivery-opening 22. To the wall of the chamber adjacent to the hammer is fixed a plate 21 having outwardly-diverging edges, and secured to each of the side walls of the chamber is an inclined cheek-piece 22, serving to move the nails toward the plate. As the nails descend from the magazine the edges of the plate 21 engage the heads of the nails and draw them outwardly in both directions. In the channel 20 are fixed opposite inner walls 22*,

lying nearer the central axis than the outer wall and against which the heads of the nails positioned by the plate 21f strike to turn the point down. Access may be had to the channel through an opening normally closed by guides 22 The feed-opening 19 is controlled by two adjacent closures or gates, these operating through an opening 23 in the inner wall of the casing and being situated in a chamber 24 within the head. One of these closures consists of a plate 25, carried upon the end of a lever 26, said lever being fulcrumed in brackets 27, fixed to the casing and having its inner angular end 28 contacting with a spring 29, which normally holds the closure in the position illustrated in Fig. 3 of the drawings. Extending along this spring 29 and the lever 26 is a fiat spring 30, contacting with the arm 28 and having an inturned end 31, furnishing the second closure, but normally lying outside the throat of the magazine.

The spring 30 is engaged by a contactpiece 32 projecting from an arm 33 of an operating member or slide 34. This slide exa slide 22, operating between tends along a groove 35, formed in the handle,

and may be guided by a pin 36, operating through an elongated o ening or slot 37. the outer end of the side is articulated one arm of an angle-lever 38, fulcrumed at 39 in a recess or groove 40 in the handle.

In the head below the delivery-opening from the channel 20 and extending to the face of the shank is formed a groove 41, continuing the channel. groove is a recess 42, in which is situated a controlling member or gate comprising a head 43 and a stem 44, extending through a bore 45 to the opposite side of the hammershank. In this head 43 is an opening 46, which may be brought into alinement with the groove 41, and outside this opening is a contact portion 47, furnishing a closure for the groove and a driving-face. In the extremity of the gate-stem is a recess 48, engaged by a reduced end portion of an arm 49, depending from the operating member. About the shank is a groove 50, in which is situated a retaining-spring 51, which may be secured in place by a screw 52. This spring is open or divided at 53, opposite the'groove 41 and Tol the walls of the spring on each side of this opening are inclined or diverge inwardly at 54.

In use the magazine is supplied with nails, and these descend by gravity through the throat, and the lowest one rests upon the plate 25. Now when it is desired to begin the feed the thumbpiece of the operating-lever is pressed inward. This brings the contact-piece against the spring 30, pressing it against the angular portion of the lever 26, which is turned about its fulcrum, and this withdraws the plate from the opening, allowing the lowermost nail to drop into the channel. At the same time the end 31 of the spring passes across the opening and again closes it, there being suflicient space between these two closures to permit the movement while the nail is resting upon the plate, but not enough to admit a second nail. The operating-lever is now released, and the spring exerts its tension to force the slide back, at the same time withdrawing the closure 31 and permitting the spring 29 to return the closure 25, upon which the succeeding nail is deposited. The nail which has passed into the channel falls with its head in contact with one of the inner side walls 22", which retards its movement, turning the point downward, so that it enters the delivery-opening and rests upon the portion 47 of the gate. A second pressure upon the operating-lever not only supplies the next nail to the channel, as has just been described, but brings the gateopening into alinement with the deliveryopening, allowing the nail to fall into the groove which continues the channel, in which it rests with its head supported by the walls 54 of the retaining-spring. The next release of the operating-lever restores the contact portion 47 to its initial position, when it will be situated above the head of the nail, as is shown in Fig. 3, furnishing a contact-face, whereupon it may be driven into the work by a preliminary blow, giving suflicient engagement with the wood to enable the hammer to be drawn away, the retaining-spring yielding to permit this. It will be seen that after the lfil st operation there is always a nail in the ehanaerreadyto pass down into the position 'for drivin upo'n the operation of the lever to feed the next nail, and the driving may be jedntinued until the supply in the magazine is exhaust d? This deviceenables the workjriianlt'o's'upplyand drive'the nails with one hand, leaving the other hand entirely free to holder; place the work. This allows such lep mtions as shingling' and lathingto be carrie'd on'with great speed. v
