WIRE-NAIL; MACHINE.

SPECIFICATION forming part of Letters Patent No. 355,3 1, dated January 4, 1887.

Application filed February 6, 1886. Serial No. 190,971. (No model.)

To all whom, it may concern.-

Be it known that I, JosErHARBErrnR, a citizen of the United States, and a resident of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Machines for Making W'ire Nails, of which the following is a specification. v

My invention is a machine in which the leading end of a wire is clamped and punched to form the nail-head when the wire is advanced a certain distance, and again clamped and cut to complete the nail, when the cut-off portion is struck laterally to eject it from the machine. V

In the accompanying drawings, Figure Lrepresents a plan view, partly in section, of a nail-machine embodying my invention. Fig. 2 represents a longitudinal central section thereof 011 line y y, Fig. 1. Fig. 3 represents a crosssection thereof on the line 00 m, Fig. 1. Fig. 4 represents an inverted plan view of the same. Figs. 5, 6, and'7 represent detailviews of parts.

Similar letters indicate similar parts.

The letter A designates the machine-frame supporting the bearings for a main shaft, B,

on which is mounted the driving-gear, hereinafter described. From the frame A rises a standard, 0, having guideways D for two clamping-blocks, D D", one of which is fixed and the other movable, and having also guide ways E for the stocks E of knives or cutters F F said knife-stocks being movable horizontally and from each other and transversely to the movable clamping-block.

G designates a feeder, which is movable horizontally to and from the clamping-blocks, and which carries a guide,H,provided with spring- 40 jaws I I, for engaging the wire passing through it, said feeder being fitted in guideways G.

S designates a punch, the stock S of which is arranged in guideways S on the machineframe to move horizontally in the plane of the wire that is fedcto the machine, and J designates a knocker arranged to vibrate in a plane intersecting the plane of the wire.

WVhen the machine is applied to use, the proper wire is passed through the guide H on the feeder G, and thence through a hole, '5, of the standard between the clamping-j aws D D the leading end ofthe wire being allowed to protrude, as indicated in Fig. 2. If the machine is then put in operation, the movable clamping jaw or block D is forced against its fellow jaw, D, thereby firmly clamping the Wire. The punch S is then forced against the protruding end of the wire, whereby such end is flattened, so as to take the form ol'a nail-head.

The feeder G is then moved in ward to advance the wire, the latter having in the meantime been released by the clamping-jaws and the punch having receded. The distance to which the wire is thus advanced determines the length of the nail, and when the feeder has completedits stroke the wire is again clamped by means of the proper jaws, when the cutters F F are moved toward each other, so as to act jointly on the'wire to sever it. The knocker J is then moved toward the wire, so as to strike against the part cut off and eject the same from the machine, it being broken off in case the same should still adhere to the wire strand. I

In the example shown the required motion of the parts is produced by the following mechanism.

At a point below the bed of the machine is an oscillating lever, K, which has its fulcrum in coincident pivots K, and carries rollers K whereby it engages the peripheries of camwheels K of the main shaft at one end, while it carries a stud, K, whereby it engages the movable clamping-jaw D at the other end. Said clamp-operatinglever K is bifurcated, as shown in Fig. 4, and the cam-wheels K which are two in number, act on the respective branches thereof. The fixed clamping-jaw D is secured to the standard 0 by means of a setscrew, L, to permit its adjustment in relation to the movable jaw. On the main shaft is a crank, N, the pitman N, of which is connected to the punch-stock S for properly reciprocating the punch. The position of the punchstock S and of the punch projecting therefrom is substantially in the horizontal plane of the main shaft B, as shown in Fig. 2, and by this arrangement a very effective operation of the punch is produced, inasmuch as the power is applied in the line of the thrust of the punch. 011 the bed of the machine are two oscillating levers, 0, each of which has its fulcrum in a pivot, O, and which carries a roller, 0 whereby it engages a cam, 0 at I thenail.

one end, while it is fitted between two lugs, O", of the knife-stocks E, respectively, for engaging the latter at the other end. The motion of the levers O is produced in one direction by means of the cams O, the action thereof being to trip said levers at the required intervals, and in the other direction by means of springs 0 and said cams are formed by means of lateral projections 011 the canrwheels K so that these wheels impart motion to both the clamp-operating lever K and the knife-operat ing lever from the same shaft. Below the feeder G is a rock-shaft, P, carrying an arm, P, the free end of which is fitted betweenlugs 1? of the feeder for engaging the latter, and also carrying a second arm, P, which is connected by means of a rod, 1?, with an eccentric-pin, F of a wheehl, of the main shaft. The eccentric-pin 1? is connected to the wheel ,P by means of radial slide P and set-screw P so that said pin may be adjusted in relation to the axis of the wheel for regulating the mo tion of the feeder and the consequent length of The knocker J is secured to one end of an oscillating lever, Q, which has its fulcrum intermediate of the ends in a pivot, Q, of a bracket, f, and which carries a roller, Q", at the other end, whereby it engages a cam, Q, of a wheel, Q, of the main shaft at the other end, so that the k nocker, together with its lever, obtains a positive motion in both directions.

I am aware that independent cams have heretofore been used to act on the knife-operating levers and clamp-operating levers, and also that two conjoined cams have been used, one to operate a clearer slide or knoeker, and

I do not claim such as my invention, a very important feature of which is the employment of conjoined cams to act on the knife-operating lever and clamp-operating lever, and another the construction of a knoeker-operating cam integral with a fly-wheel, as described,

whereby the machine is rendered very compact and eiiective in operation.

WVhat I claim as new, and desire to secure by Letters Patent, is

1. In a wire-nail machine, a main drivingshaft on which are mounted two double camsthat is to say, each cam having both peripheral and lateral projections to operate, respectively, the gripping and cutting levers, the bifurcated lever K, supported beneath the bed. of the machine and provided with the stud K, and the rollerK jointly with thegr-ipping, heading, and cutting dies described, to complete the nail in the manner set forth.

2.v In a wire-nail machine, the clamping blocks D D, the latter being movable vertically by the bifurcated lever. K, having stud K, the cutters F F mounted on cutter-stock E, the latter having lugs O, with which levers O engage to reciprocate said cutter-stocks, cams O feed-plate G, provided with the lugs I and guide H, in which latter are the curved spring-jaws I, arm I and shaft P, jointly with mechanism for operating said parts, and with cutting and heading-dies to complete the nail, in the manner set forth.
