To @ZZ whom z' 71mg/ concern:

Be it known that we, EDWARD L. TAFT, of Gardner, in the county of Vorcester and State ot' Massachusetts, and HENRY M. RICH, of Athol, in the county of Vorcester and State of Massachusetts, have invented a new and Improved Automatic Nailer, of which the following is a full, clear, and exact description.

rlhe object of our invention is to provide a new and improved device for forcing nails through sticks or rods-such as rattan, reed, CC.

The invention consists in the construction of parts and details, as will be fully set forth hereinafter, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure l is a side view of our improved nailer before the nail is driven. Fig.2 is a plan view of the same, parts being broken out and others in section. Fig. 3 is a side view of the same after the nail has been driven. Fig. i is a plan view of the feeding device. Fig. 5 is a side view of our improved nailer, he jaws being spread to receive the rod. Fig. (5 is Va plan view of the feeder anddevices for carrying the nails. Fig. 7 is a side view of the sliding cam-piece. Fig. 8 is a bottom view ot' the nail-holding sockets.

Two levers, A and4 B, are pivoted together, and are provided with the jaws A and B'. Ou the pivot C is loosely mounted a bar, D, in such a manner that it can turn independently of either lever Aor B. At the rear end of bar D, between the levers A B, a boX, D', for receiving the paper of nails E, is formed, which box has a suitable cover. A spring, E', is heid between the bottoni of the box D' and the lever B, pins Ey projecting from the inner edge of the lever B and the bottoni of the box D' into the ends of the spiral spring E'. A lever, F, provided with a lug, F', is pivoted to the side of the bar D, behind the pivot C, by means of a pivot, F2, passed through the lug F' into the bar D, so that the said lever F can turn on the pivot F2. The lever Fis provided at its rear end with an irregular U- shaped recess, F", into which a pin, F*, projects frorn the outer side of the lever B. Neal the middle the lever F is curved upward, an( on its front end it is provided with the trans verse piece G, in which a slightly-curved slot` G', is formed, and at the bend the lever F i: provided with au irregular L- shaped slot, H having the two opposite shoulders H' and H on opposite sides. In the outer surface of th bar D a earn-piece, I, is mounted to slide trans Versely to the width of said cani-piece I-tha is, in the direction from one jaw tothe otherwhich cam-piece I is shown on an enlarge( scale in Fig. 7. A pin, I', projects from th piece I through the slot G' in the end of tht lever F. On the lower end of the piece I s notclnl, is formed in each side edge, and forms an upwardly-projecting prong, 1*, at the lowel end of each side edge ofthe piece I. A pin, J, carrying a roller, projects into the rear recess, I, ol' the ca1npiece I, which pin is formed or the outer edge of a bar, K, held by pins o1 screws k to slide on the bottom edge of the bai D, and provided at its end with ahalf-socket. K', for receiving the nail. The said bar K if provided with longitudinal slots, througl which the screws 7c pass that hold it on the un der side of the bar D. A bar, L, is held t( slide on the outer side of the barD by a screw. L2, passed through a longitudinal slot, L, i1: the said bar L, and on the outer end of tht said bar L a half-socket, L', is formed, whicl tits against the half-socket K', formed on th( end of the bar K. A pin, J2, on the inner enc of the bar L, passes into the notch I3 in the front edge of the cam-piece I. The front edge of the bar D has a curved rabbeted edge, M, which passes into a grooved lug or hook, M', formed on the end of the jaw B', t-he end oi which jaw is provided with a projection o1 hammer-head, N, that drives the nails. The bottom socket-piece, L', has its inner edge beveled, as shown in dotted lines in Fig. l, sc that when the hammer-head N strikes the said bevel it can force the said socket outward, as will be fully set forth' hereinafter. Into the L-shaped slot H a pin, O', projects from a crank, O, pivoted in a suitable recess in thc outer side of the bar D, which crank O is ou one end of a short shaft, O2, passed through the bar D,and provided on the other end with a crank, P, provided on its swinging end with a longitudinal slot, P, into which a pin, P2, passes. The said crank P slides in the recess P3 in a plate, Pf, forming the covering of a longitudinal cavity or recess, Q, in the inner surface of the bar D. The above-mentioned pin P2 is connected with the sliding feedbar B, having a pointedhead or prong, R', formed on its free end, which head is provided with a shoulder, B2, in its inner edge. The outer edge of the head B is inclined outward slightly. A slning-catch, S, provided with a hookhead, S, which is forked as is shown in Fig. 4, is secured to the inner surface of the feed-bar B a short distance from the free end ofthe same. A spring, S2, is secured on the plate PL and rests on the outer surface of the feedbar B. Springs T, secured on the inner surface of the plate Prest against the nails a on the nailtape Ein the cavity or recessQ in the barD. A shoulder/His formed in the inner side of the bar D at the front edge. The inner end ofthe bar Krests upon and is guided by a clip, U, formed on the bar D. The nailholding sockets K and L are provided in their bottom edges with very small notches,forming an aperture, XV, through which the nails can pass, as is shown in Fig. 8.

The operation is as follows: The jaws A B :i are separated, and the stick or rod through which the nail is to be driven isy passed between thejaws, as is shown in dotted lines in Fig. 1, the nail being heid between the feeding-bar B and the hook S' on the end of the spring S on the said bar, the nail resting against the shoulder B2 at the end of the feeding-bar. The point of the nail is direct-ly over the aperture XV, between the two halfsockets L and K'. The handle-levers AB are pressed together, and the hammer-head N on the jaw B is pressed on the head of the nail, whereby the nail is pressed downward. By pressing' down the jaws the L-shaped slot H, acting on the pin 0, swings down the crank O, whereby the crank P is swung toward the rear of the device and pulls back the feedingbar B. By this time a nail has been forced down, so that it can be held by jaws L K. By pressing the handles together still farther the nail is forced into the wood, and by the time the head N passes down into the socket in which the nail is held the upper end of the slot G strikes the pin I and forces down the cam-piece I, so as to permit the head Nto act on the bevel ofthe sockets, to force the bar L toward the front of the instrument, and the sliding bar K, on the bottom of `bar D, is moved toward the rear. The levers are then pressed together until the nail has been driven entirely into the stick. When the handles A B are released, they are separated by the spring E. the pin F* strikes the end of the slot F,and swings up the front end of thelever F, causing the bottom of the slot G to strike the pin l', whereby the cam-plate I is pulled up, and the cam projections 14, acting on the pin J2 and the pin J, pull the bar L toward the rear and force the bar K forward,whereby the two socket-sections are brought in contact ready for a fresh nail. At the same time the bottom of the slot H, acting on the pin O', swings up the crank O, whereby the crank P is swung down, and the slot P, acting ou the pin P2, forces forward-that is, toward the front end of the instrument-the feed bar R, the hook-prong of which catches on one of the nails held on the nail-tape E and draws the entire tape forward, the nail being held, as above specified, by the hook of the feedingbar and the hook S of the spring S. The springs T hold the tape from moving out too far, and the feeder-bar is projected beyond the end of the tape, whereby the nail held by the feedingbar is separated from the tape, and the paper adhering to the said nail is torn off. The spring S2 presses the feeding-bar against the tape. When the nail has been driven, the above-described operation is completed.

The device can be made in different sizes, according to the sizeof the nails to be driven.

Having thus fully described our invention, we claim as new and desire to secure by Letters Patent- 1.
