IWlRE-NA-BL MACHINE.

SPECIFICATION forming part of Letters Patent No. 330,219, dated November 10, 1885 Application filed September (3, 1883. Renewed May 1, 1885. Serial No. 164,058. (No model.)

To all whom it may concern Be it known that I, JOHN S. FOLLANSBEE, a citizen of the United States,residing at Bridgeport, inthe county of Fairfield and State of Connecticut, have invented certain new and useful Improvements in Wire-N ail Machines; and I do herebydeclare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. l

My invention relates to certain novel and useful improvements in machines for manufacturing nails from wire, and has for its ob- I ject to simplify the construction of machines of this description and reduce the cost of manufacture; and with these ends in view my invention consists in the details of constructlon and combination of elements hereinafter ally designated by the claims.

In order thatthoseskilled in the artto fully and in detail explained, and then specificstand more fully how to make and use my improvement, I will proceed to describe the construction and operation of the same, referring 1 by letters to. the accompanying drawings,

forming part of this specification, in which F1gure 1 is a plan view of my improvement;

Fig. 2, an end elevation of the same; Fig. 3,a

detail view illustrating the cutting and head ing mechanism; Fig. 4, a section taken at the line a: a: of Fig. 1; Fig. 5, a detail viewshowingthe manner in which the cutter issecurcd to the plate which carries it; Fig. 6, a detail side elevation of the carrier-wheel and pointing-dies and means for operating them. Fig. 7, is a detail View illustrating the double-acting cam; Fig. 8, a detail front view showing the relative position of the pointing-dies and 1 the carrier-wheel; Fig. 9, a section through the liney y of Fig. 1; Fig. 10,a section through the. line 2 z of Fig. 1; Fig. 11, a detail perspective illustrating the shape of the pointingdies, and Fig. 12 a detail perspective of the band which extends partially around the carrier-wheel.

Similar letters denote like parts inthe several figures of the drawings.

A isthe bed-plate, and B B raised portions at the rear end thereof, forming guideways.

which motion will of course be communicated by the lever E. At. one end of this lever is attached in any ordinary way, or vcast integral therewith, a downwardly-projecting lug, I, which is adapted to rest upon the face of the cam G.

J isa traveler, having a rib, K, on its bot tom (see Fig. 9,) adapted to slide within the guideways B. Rigidly secured to this traveler is a spindle, L, over which are placed disks M in such manner as to move freelyup and down.

I An opening, N, is made through the spindle which my invention appertains may underto admit the wire between the disks,as will be presently explained. The other end of the lever E is placed over the spindleimmediately upon the upper disk. The lug I is kept in constant contact with the side of the cam O by means of a spring, 0, attached to the lever E and pin 1?. As the shaft D revolves the face of the cam will operate to raise that end, which I will term the heel 0f the lever, resting on it through the medium of the lug I, thereby depressing the other end and causing the disks M to act as jaws and close upon the wire, so as to hold it fast. The side of the camnow throws the heel of the lever backward, there by causing the forward end to swing forward, carrying with it, of course, the traveler and disks, and consequently the wire.- The position of the mechanism and parts so far described is now such as shown at Fig. 1. As

the shaft 1) continues to revolve the cam G will cease to operate the lever E, and the latter will be returnedto its normal position by means of the spring 0. By this latter movement the disks M will be carried back over the wire.

Q is a lever pivoted by the pin R, and with its heel end resting against a cam, S, on the shaft D. T is a screw passed through the forward extremity of this lever, so as to project downward below the lever. When the wire has been fed forward by the actionof the lever E, the cam S will raise the heel of the leverQ and cause the forward end to be depressed, and thereby bring the'screw T down upon the wire, so as to keep the latter from being carried backward by the friction of the disks during their return movement. The screw T may be adjusted in and out, therebyvarying' the pressure on the wire, or compensating for any wear. U is an ordinary set-screw passed through a bearing, V, between the guideways B, and by the adjustment of said screw the play of the traveler J is regulated to determine the amount of wire to be fedat each forward movement. W is a presser-bar pivoted between the standards X, and having at its heel end an ordinary cam-ball, Y. This ball forms the extremity of the spring-arm Y,-which is bolted or otherwise secured at the other end to the under side of the presser-bar.

Y is an ordinary adj usting-screw operating against the upper surface of the cam-ball, for the purpose of throwing the latter more or-less within the field of action of the cam-wheelZ on the shaft D, as will be seen by reference to Figs. 1 and 4:.

A is a clamp-bar bolted at one end to the bed-plate, as seen at Fig. 4, and provided at the other extremity with a downwardly-projecting lug, B, which extends immediately over the path of the wire. The upper forward portion of the clamping-bar and the lower forward portion of the presser-bar are pro vided with recesses G, curved in cross-section, and within these recesses is placed a .connecting-plate, D; so that it will .be readily .understood that any motion of the presser-bar in a 1 vertical plane will be communicated to the; clamp-bar. As the cam Z revolves it will opf erate the cam-ball Y, and thereby throw the forward end of the presser-bar downward, which will cause the clamp-bar to be forced against the wire, as shown in Fig. 4.. When the cam Zhas ceased to act on the presser-;bar, the latter will return to its normal position by gravity, while the resiliency of the clamp-bar will return the latter, and thereby insure the; retention of the connecting-plate. Should a? greater or less pressure be desired, this mayi readily be accomplished by the adjustment of the screw Y, as will be readily .understood. E F are arms pivoted at G, soas to form a; toggle-joint. The extremity of the arm E lSf pivoted to an adjustable block, H, secured to the bed-plate by a bolt, I, passing throughau elongated slot, J. The arm F is pivoted to a block, K, arranged to slide in guideways-ini the bed-plate in any'ordinary way. I

L is the tool for forming the heads on the nails, and is secured to the block K, as shown.

-K, arranged on the short shaft L.

Figs. 1 and 2.)

Iterm a plunger-rod, N, so as to form a conection between the arms E F. and said rod, for the purpose presently explained. This plunger is confined as against lateral play by means of guideways 0, (see Fig. 10,) and is provided with a lug, P, which projects upward through an elongated slot, Q,'in a plate, It, the latter being securely fastened to the bed-plate.

Theplunger is operated bya cam, S, on the shaft D, as follows: As the shaft revolves the said cam will strike against the plunger, force it vforward, and thereby cause the arms E F to straighten out and drive the heading-tool L against the wire, as will be presently ex-v plained. I

By manipulating the adjusting-screw T a greater or less throw may be impartedto the heading-tool, as the case may be.

U is a spring bearing against the link M, as shown, andserves to return the plunger and arms'to their normal position.

V is a plate arranged to slide within ways W .on the bed-plate. Secured on the plate V, at the forward extremity thereof, are the cutting-tool X and push-out Y. These are held in position by means of caps Z secured by screws, as clearly shown at Figs. 3 and 5.

A are setscrews passed through the raised portion B of the plate against the cuttingtool and push-out, by means of which the latter may be adjusted to compensate for wear,or for other obvious purposes.

0 is-a projection attached to or cast integral with the plate V,.and is operated by the cam D. v

E E are raised portions of the bed-plate, having grooves F for the wire. These raised portions also form guideways for the cuttingtool and push-out, and prevent any unsteadiness or unnecessary wabbling of the same. When the cam D strikes the projection O, the cutting-tool and push-out will be forced forward, thereby causing the wire to be severed and be pushed by the cutter and push-out from out the supports E into the carrierwheel G. The spring H serves to return the plate V to its normal position.

I is a cog on the shaft D, and meshes into .acog-wheel, J, journaled within-the bedplate. This latter wheel has a beveled gear .on its face, which meshes into a beveled. gear, (See M is a wheel on the shaft L, and having on its periphery a short worm or track, N, which o erates the wheel 0 in the ordinary way,

each complete revolution of the wheel M .causing the worm to act on one tooth of the wheel 0, so that the motion of the latter is intermittent. The wheel 0 is attached to the shaft P, which is j ournaled within the standard Q, bolted to the bed-plate, and secured to the other extremity of this shaft is the carrier-wheel G, whose function and operation will be presently explained.

Bolted to the bed-plate, or .cast integral therewith, is an uprightpost,R,having therein dovetailed bearings, as clearly shown at Fig. 1. Extending laterally from this post is a bearing, S, through which is journaled the shaft T. A rocking motion is imparted to this shaft by means of a rod, U, attached to a crank-pin, V, on the wheel W, arranged on the shaft D, the other extremity of the rod being similarly attached to a crank-arm, X, (see Figs. 1, 2, and 6,) the rod U being of course attached to the crankarm X at a point farther from the axis of the shaft T than the distance of the pin V from the axis of the shaft D. Within the dovetailed bearing in the post It is a die-box, Y, arranged to slide freely ina vertical plane,and operated by an eccentric actuated by the movement of the shaft T. The operation and construction of the mechanism for imparting motion to the die-box is so old and well known, being common to nearly every machine-press, that I will not enter into any description of the same.

Cutting-dies Z Z are secured one within the die-box and the other immediately below upon the post R, as clearly shown at Figs. 6 and 8. The shape of the dies is illustrated at Fig. 11; so that it will be readily understood that when a nail is placed between them the upper die will force the wire down against the lower die so that the latter will cut through the wire, the upper die meantime performing a similar function, the result being that the nail ispointed.

The carrier-wheel G is arranged on the same shaft with the wheel 0, so that the intermittent motion of the latter will be imparted to the said carrier. A band, A, secured to the post R, as shown at Fig. 6, extends upwardly around the carrier-wheel, close to the periphery thereof, to the point where the cutter and push-out force the nail within the recesses within the said wheel, (see Fig. 8,) the object of this being to prevent the nails from falling out during the revolution of the wheel until they have been carried around to a suitable position, from whence they may drop by gravity into any receptacle. When the nails are forced within the carrier, they project laterally therefrom, as seen at Fig. 6. As the carrier revolves the inner or point end of the nail rides up the inclined side of the lower die, Z, and falls into the said die in the proper position so that when the upper die descends the nail may be pointed, as hereinbefore set forth.

The operation of my improvement is as follows: The wire is run through any ordinary wire-straightener and then guided into the opening N between the disks M. As the shaft D revolves the wire will be fed forward by the action of the lever E. The presser-barW and clamp-bar A operate as soon as the lever commences to return to its normal position. When the wire has been clamped by said presser and the clamp, the cam S operates the plunger N, thereby causing the heading-tool L to strike the end of the wire and form a head thereon. The cam D strikes the projection G and forces the cutting-tool and push-out forward, "0 thereby severing the wire and pushing the severed portion forward into one of the recesses in the carrier-wheel. The latter revolves step by step, as hereinbefore described, and carries the nails up into the proper position between the cuttingdies Z, which point the nails, as set forth.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. The shaft D, carrying cams 0 Z D S and wheel W, in combination with the feed ing, clamping, cutting, and push-out and heading mechanisms, rod U, and means for pointing the nails, substantially as described.

2. The die-box arranged to slide vertically within supporting-posts, in combination with shaft T, rod U, crank-pin V, and shaft D, substantially as set forth.

3. The die-box and pointing-dies, in combio nation with the shaft T, rod U, crank-pin V, shaft D, carrying cams G,S,D,and S, and the feeding, clamping, heading, and cutting mechanisms, substantially as hereinbefore set forth and described.

4. The carrier-wheel recessed in its periphcry, in combination with the wheel 0, wheel M, having worm N, band A, and pointingdies Z, substantially as described.

In testimony whereof I affix my signature in 100 presence of two witnesses.
