HORATIO CAMERON, OF BOSTON, ASSIGNOR OF ONE-HALF TO EDWIN L. EDES, OF PLYMOUTH, MASSACHUSETTS.

WIRE-NAIL MACHINE.

SPECIFICATION forming part of Letters Patent No. 390,648, dated October 9, 1888.

Application filed NovemhcrQB, 1887. Serial No. 256,303. (No modeLi T aZZ whom it may concern.-

Be it known that I, HORATIO CAMERON, a citizen of the United States, residing at Boston, in the county of Suffolk and State of Massachusetts, have invented a new and useful Improrementin AttachmenisforOuttingWire Nails and W'ire Tacks, as applied to a Blanchard tack and nail machine, of which the fol lowing is a specification.

The object of my invention is to produce an attachment for a Blanchard tack and nail machine, whereby I am enabled to make wire nails or tacks with the said machine.

The invention consists in the peculiar con struction and arrangement of the pointing, feeding, and cutting mechanism, as hereinafter fully set forth, and pointed outin the claims.

Referring to the accompanying drawings, Figure 1 represents a front view of a Blanchard tack and nail machine with my invention applied thereto. Fig. 2 is a rear view of the fcedingbar; Fig. 3, a side view of the same. Fig. 4. shows, respectively, a section through a: x of Fig. 2 and through 3 y. Fig. 5 showsa rear view of a modification of the feed bar. Fig. 6 is a side view of same. Fig. 7 is a detail view showing the wire pointed and ready to be cut ofi. Fig. 8 is ,a plan or top view of same. Fig. 9 is a view showing the wire cut off and carried down to the heading mechanism. Fig. 10 is a plan or top view of same.

A represents the frame of a Blanchard tack or nail machine; B, the shaft upon which are mounted the gripping-lever O and camsD D, for operating the cutting -jaws E E Upon one end of the shaft 13 is mounted the driving wheel or pulley D and upon the other end is In the Blanchard machine to each of the out ting-jaws E E a knife is secured parallel with the front of the machine. These I dispense with, and in their place arrange the following mechanism: To the inner side of the cuttingjaw E, I secure a knife, M, so that the knife is at right angles to the front of the machine and next to the jaw E and to the said jaw E, I also secure a die, N, and to the bed-piece F, I secure a corresponding die, P. These dies N and P are for pointing the wire, as will be hereinafter fully explained. To the otherjaw, E, I secure a stay, Q, for steadying the knife M while cutting the wire.

To one side of the frame of the machine I secure a plate, R, provided with aslot, 1". (See Fig. 1.) This plate is for carrying the feedbar S, which is connected thereto by a stud, T. This stud consists of a central portion, t, of slightly larger diameter than the ends 75 t which are both screw-threaded. (See Fig. 4.) Upon the portion is placed a washer, to, that bears against the shoulder. The bolt t is then passed through the slot 0* in the plate R and securedby a nut, 12. Upon the central portion, 25, is placed a sleeve, w, which is passed through a slot, 8, in the feed-bar S, and then clamped thereon by a nut, a", the sleeve being held on the stud by a nut,

At the upper end of the feed bar S is secured a bolt, a, provided at its'inner end with a roller, 6, that works in a cam, 0, cut in the periphery of the disk K. The lower endof the bar S is bent at right angles, and is provided with a teat or small projection, d.

e is a small arm fulcrumed atf on the rear of the feed-bar S, and is provided with a slot, in which a chisel-pointed piece of metal, g, is se' cured by a set-screw, h. Against the upper part of'the pieceg the free end of a spring, j, presses, as shown. The wire to be fed to the machine passes between the teat d and the piece 9.

It will be seen that the stud T can be adjusted to any required position on the plate R, thereby regulating the fulcrum of the feed-bar according as it is desired to feed the wire for a short or long nail, a reciprocating motion being imparted to the upper end of the feedbar S by the cam c, and consequently an opposite motion is imparted to the lower end, which feeds the wire forward, the piece 1 being free to ride over the wire when the end of the feed-bar is moving backward; but when moving forward the wire is gripped between the piece 9 and teat (Z and carried therewith.

Between the feed-bar and the knife I fix a tube, X, to guide the wireinto the lower pointing-disk.

When it is desired to make very long nails, instead of attaching the ,teat (1, piece g, and springj directly onto the feed-bar S, I secure them to a slide, U, that works in a guide, V, (see Figs. 5 and 6,) secured to the frame of the machine. The slide U is provided with a pin or stud, 7c, and the end of the feed-bar S is formed with a saddle to fitover same,as shown. The object of this arrangement is to feed the wire in a straight line, as with verylong nails the swing of the lower end of the feedbar S would be so great as to raise the wire to an objectionable height above the cntting-off and pointing mechanism.

The operation is as follows: The wire being pointed and in the position shown in Fig. 7 and the machine started, the cams D D cause both the cutting'jaws E E to descend until the knife M has cut off the wire,when the jaw E comes to a standstill, while thejaw E continues to descend. The piece of wire that has been out off, being held between the knife M and the carrier L, is carried down to the gripping-jaws 0 O to be headed in the usual manner. Just before the cutoff piece is delivered to the gripping-jaws the dieNcomes into contact with the end of the wire and forms a point thereon. lVhile the wire is held by the die N as it forms a point the feed-bar S is thrown l back ready to push the wire forward. The jaw E now rises until the lower edge of the knife is on a level with the bottom of the stay Q, when both thejaws E E rise together until they are a short distance above the die 1?, when they both come to a standstill, and the feed-bar S is then operated to push the wire forward the required distance, when the jaws E E again descend and the operation is repeated.

Vhat I claim as my invention is 1. In combination with the cutting-jaws E E of a tack or nail machine, the knife M, stay Q, and pointing-dies N P, substantially as and for the purposes set forth.

2. The stud T, consisting of the central portion, 1, ends '6' i washer a, nut 12, sleeve w, nut .13, and nut 31, in combination with the feed-bar S, provided with a slot, 8, and plate R, pro vided with a slot, 0, substantially as and for the purposes set forth.

8. The slide U, provided with arm e,chiselpointed piece 9, spring 7', teat d, and pin or stud It, in combination with the guide V and feed-bar S, substantially as and for the purposes set forth.

4. The stay Q, knife M, and pointing-die N, secured to the cutting-jaws of a tack and nail machine,in combination with a fixed pointing die, I, and feed-barS, constructed and operated substantially as and for the purposes set forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

IIOBATIO CAMERON.
