ATTACHMENT FOR NAIL MACHlNES.

SPECIFICATION forming part of Letters Patent No. 391,465, dated October 23,1888.

Application filed July 20, 1888.

To all whom it may concern:

Be it known that we, PHILIP MORGAN GIB- BONS, WILLIs K. TorLEY, and GEORGE F. BROWN, citizens of the United States, residing at Sunbury, in the county of Northumberland and State of Pennsylvania, have invented a new and useful Improvements in Attachments for Nail-Machines, of which the following is a specification.

Our invention relates to an improvement in attachments for nail-machines; and it consists in the peculiar construction and combination of devices, that will be more fully set forth hereinafter, and particularly pointed out in the r 5 claims.

The object of our invention is to provide at tachments for nail-cutting machines, whereby the latter may be used for making wire nails, thus enabling the machine to make either cut or wire nails at will.

In the accompanying drawings, Figure 1 is a top plan view of a nail-cutting machine provided with wire-nail attachments embodying our improvements. Fig. 2 is a side elevation of the same. Fig. 3 is a vertical longitudinal sectional view taken on the line x as of Fig. 1. Fig. at is a vertical transverse sectional View taken on the line 3 y of Fig. 1. Fig. 5 is a front elevation of a nail-cutting mao chine provided with our improved wire-nail- I making attachments, and illustrating a modified form of the same. Fig. 6 is a detail perspective view of the gripping device for feeding the wire to the machine.

A represents a rectangular frame, which is provided at itsfront and rear corners with supporting-legs B C, respectively. The latter have vertical arms or standards at their upper ends, which project above the frame, and are 0 provided with bearings D,in which is journaled a shaft, E. The same is provided at its center with an eceentriccam, F. To one end of the shaft E is secured a crank-wheel, G, and to the opposite end thereof are secured a balance-wheel, H, and a pulley, I, the latter being adapted to be driven by an endless belt from a suitable counter-shaft in the usual man- Arranged transversely in the frame A, near Serial No. 280,459. (No model.)

the center of the same, is a bar, K, and paral- 5o lel with said bar, and at a suitable distance in front of the same, is a rock-shaft, L. Project ing rearward and upward from the center of the rock-shaft is a lever, M,which bears against the eccentriccam F, and is thereby operated 5 5 by the latter when the same is in rotation. The lower end of the lever M is arranged at substantially right angles, and is provided in its upper side with a longitudinal recess,N, which constitutes a dieholder, as will be hereinafter described.

0 represents a rocking frame, which is arranged longitudinally on the frame A, at one side of the frame, and has a pair of ears or arms, P, which bear against the front side of the frame and the rear side of the bar K, and are pivoted on bolts or pins R, which are in line with each other. From the outer corner of the rocking frame projects an upwardlycurved arm, S, the inner end of which is provided with an extension, '1. In the inner side of the rocking frame, near the center thereof, is a recess, U, for the purpose to be hereinafter stated.

V represents a rocking yoke, which is substantiallyin the shape of aninverted letter U, and has trunnions at its ends, which are journaled in bearings \V on the frame, said yoke being arranged transversely on the same and atasuitabledistancefrom thefrontsidethereoi. 8o Near the center of the yoke, on its front side, is the usual recess, X, in which a die is ordinarily secured when the machine is used for making cut nails; but when the machine is provided with our improved attachments for making wire nails the said dieis removed,and hence the same is omitted in the drawings. From one end of the yoke V projects an arm,

Y, which extends rearward, and is connected to the crank-wheel G by means of a link, Z, 0 whereby the rotation of the Wheel G causes the arm Y to oscillate, and thereby rock the yoke. The said arm is provided at its. lower front corner with an extension or lug, A, which is arranged under and at a distance from the ex- 5 tension T of the rocking frame 0.

B represents a tumbling link, which has its ends inserted in recesses in the opposing sides of the extension T and lug A, and thereby causes the rocking arm Yto impart corresponding motion to the frame 0.

G representsa coiled retractile spring,which has its lower end secured to a pin, D, that projects from one of the legs B and has its upper end secured to the outer corner of the rocking frame 0. The function of this spring is to normally lower the outer end of the arm S,and thereby return the rocking frame to itsinitial position. When the said arm is sufficiently heavy to return the rocking frame to its initial position, the spring 0 may be dispensed with, if preferred.

On the center of the front side of the frame A is a rigid die plate or holder, E, which is provided in its upper side with a rectangular recess, F.

G represents an arm or ledge, which projects from one of the front corners of the frame.

The machine so far described is the usual nail-cutting machine now in common use, and we make no claims in this application to any of the hereinbefore-described parts of the said machine, and we have illustrated the same herein only for the purpose of making plain the construction and operation of our improved attachments, whereby the said machine may, without alteration of any part thereof, be employed to make wire nails.

We will now describe our improved wirenail-making attachments to the nail-cutting machine.

a represents a pair of parallel guides, which are located transversely on one side of the frame between the ledge or arm G and the proximate bearing W. The said guides are provided on their opposing inner sides with longitudinal grooves b, which are engaged by longitudinal flanges d on opposite sides of a reciprocating plate, c. From the upper side of said plate, at a suitable distance from the inner end thereof, project a pair of lugs or ears, f, between which is fulcrumed a rocking jaw, g, the latter having on its under side a longitudinal inverted-\I-shaped groove, H. From the upper side of the said jaw, at asuitable distance from the outer end thereof, projects an arm, i. The said plate e and the said rocking jaw constitute a gripping device, which is adapted to grasp a wire and feedthe same automatically to the machine, in the manner hereinafter described.

Alever, 7c, is fulcrumed near its outer end on a pin, Z, which projects upward from theledge or arm G, near the outer corner thereof, and the inner end of said lever is provided with a longitudinal open slot, m, which receives the arm 2', and thereby the said lever is connected to the rocking jaw of the gripping and feed device.

n represents a pitman, which is pivoted at one end on a pin or spindle, 0', that projects from the outer side of the arm S, and the opposite end of the said pitman is pivotally connected to thelever-arm Icata suitable distance from the fulcrum Z thereof by means of a pin or bolt, 1).

0 represents a heading-die, which is arranged in the recess U of the rocking frame 0,and is of the form here shown. Secured in the recess N of the rocking lever M are dies 8 and t, and secured in the recess F of the die plate or holder are countersunk dies 8 and t. The dies 8 ands have their meeting ends adapted to grip and hold the wire-nail blank, and the dies t and t have their meeting ends adapted to point the wire nails and sever the blank from the Wire rod.

The operation of ourinvention is as follows: A wire, u,of suitable size and material, is introduced from a continuous roll (not shown,) through the groove h of the gripping device and through the guide-opening e in a plate, to, which is secured to the die plate or holder E. We will assume that the machine is in its initial position when the eccentric-cam F is raised, so as to raise the lever M, and thereby close the dies and counter-dies s s t it against each other and cause the tumbling link I) to raise the outer side of the rocking frame, so as to incline the die 9" toward the dies 8 s and cause the pitman a to move the inner end of the lever outward, so as to move the gripping device outward on the wire a, while the latter remains at rest. As the shaft E rotates the cam F lowers the outer end of the lever M, and thereby rocks the shaft L, so as to cause the gripping and cutting dies 8 t to recede from the counter-dies s and t. The crank-wheel G and link Z elevate the rear end of the lever Y, so as to rock the yoke V forward and cause the tumbling link B to start the rocking frame 0 in its descending movement. The said frame thereby draws the pitman n and causes the latter to move the lever-arm 7c inward on the ledge or arm G, and the said lever being in engagement with the arm 2' of thejaw g, the latter is turned on its axis and caused to clamp the wire a firmly on the plate 6, and thegripping device is then moved inward, so as to thrust the ends of the wire past and between the ends of the dies and counter-dies. As the machine continues to operate, the dies and counter-dies, when their opposing ends come in contact with each other, serve to securely grip the wire and to form a pointed end to that portion of the wire which constitutes the blank and sever the same, and the machine is so timed that in the instant succeeding this gripping and cutting action of the dies and counterdies the rocking frame 0 is moved upward by IIO the crank-wheel G, links Z, arm Y, and tumbling link B, so as to cause the heading-die r to be so forcibly compressed against the outer end of the blank as to form the head of the nail. The machine is illustrated in this position in the variousv figures of the drawings.

By regulating the distance between the fulcrum Z and the connectingpin p of the lever is the gripping and feeding device may be caused to move any desired distance, so as to feed a sufficient length of the wire between the dies and counter-dies, according to the desired length of the nail.

In Fig. 5 we illustrate a modified form of our invention, in which the pitman n and lever 7c are dispensed with and a 1lIlk,l ,employed in lieu thereof, the said link having one end pivotally connected to a pin, a, on the arm B, and its opposite end forked or bifurcated and pivotally connected by a pin, N, to opposite sides of thejaw g of the gripping device.

Wire-nail machines now in common use are exceedingly large, heavy, and costly, and require a great deal of power to operate them, while the nail-cutting machines such as herein illustrated and described and now in common use are comparatively small, light, and require only a minimum expenditure of power to run them.

Our' improved attachments, hereinbefore described, adapted for use in connection with such nail-cutting machines, enable said machines to be successfully employed in making wire nailswithout in any Wise altering the construction of said machines and without impairing their usefulness for cutting nails, and hence a person owning one ofsuch nail-cutting machines, and also provided with our improved attachment therefor, may use the machine either for making out nails or for making wire nails, at will.

Having thus described our invention, we claim- 1. In a nail-machine, the combination of the rigid die plate or holder E, the counter-dies s t, secured therein, the rock-shaft L,the dies 8 t, secured thereto, the rocking frame 0, the header-die 1', secured thereto and arranged at right angles to the dies and counter-dies and in line with the meeting end of the dies and counter-dies,the guide 10, opposite the headerdie and secured to the plate or holder E,and the feeder connected to and operated by the rocking frame 0, substantially as described.

2. The combination, in a nail-machine, of the rock-shaft L,having the lever M, the dies 8 t,adapted to be secured to the rock-shaft, the die plate or holder E, rigid on the frame of the machine, the counter-dies s t, secured in said plate or holder, the rocking frame 0, the heading-die r,secured therein,the plate e,movable longitudinally in suitable guides and arranged in line with the heading-die, the jaw g, pivoted on said plate, the guide to, for the purpose set forth, and connections, substantially as set forth, between the jaw g and the rocking frame 0, substantially as described.

3. The combination, in a nail-making machine, of the rocking frame 0, the longitudinally-movable plate 6, the c1amping-jawg,pivoted thereon, the lever is, engaging and connected to the said jaw, and the pitman conmeeting said lever to the rocking frame, substantially as described.

4.. In a nail-making machine, the rigid die plate or holder E,having the counter-dies,the guide w, secured to said die plate or holder, and the rock-shaft having the die, the guide being arranged in line with the meeting ends of the dies and counter-dies, substantially as described.

In testimony that we claim the foregoing as our own we have hereto affixed our signatures in presence of two witnesses.
