MROVED MACHINE vP01-I2 FORGING- BRSE-SHOE Kms.

The Schedule referred to Ln these Lettera Patent and making part o! the mmc To all to whom Ait may concern.

Be it known that we, J OHN Huoonfr'r and Joux ALBERT HUoGE'rT, of Eastbourne, in the county oi' Sussex, England, subjects of the Queen of Great Britaiu, have inventedor discovered new and useful Improvements in the Manufacture of Horse-Nails, and other nails, and in MachineryY used therein and we, the said JOHN HUGGETT and JOHN ALBERT HUG- GETT, do hereby declare the nature of the said invention, aud'in what manner the same is to be performed, to be particularly described and ascertained in and by the following statement thereof; that is to say:

This invention has for its object, improvements in the manufacture of horse-nails, and other nails, and in machinery `used therein.

We employ a hammer, worked by power, by which ak regular reciprocating motion is given to it.

On the face of the hammer are two dies, one corresponding in form to the side of the nail, and the other to its edge.

This hammer works upon an anvil, also having the incline or bevel ofthe nail formed upon it.

The bar of iron which is to be drawn down to form a nail, is received into a holder, which tuins it onequarter round, and shifts it sideways from one die of the hammer to the other, after each blow, so that the bar may be alternately struck on the side and edge,v and alternately by one and the other of the dies which the hammer carries.

-Thepholdcr for the bar to be drawn down may couveniently be an axis connected with -the hammer, so that it turns one-quarter round between each'stroke, rst one way, then the other.

And in order that our said invention may be most fully understood and readily carried into eect, we will proceed to describe the drawings hereunto annexed.

`Descripim of the Drawings.

Figure 1 is a side view of the.apparatus which we employ;A

Figure 2 isau end view; and

Figure 3 is a. plan, partly in section, ofthe same. 'g'

a a is the frame ofthe machine.

It has -npou it a standard, a, carrying the main axis, b, on which there are fastan loose pulleys, b', to receive a driving-belt.

b* is an eccentric ou this axis, receiving an eccentric rod, c, which, at its other end, is jointed to the springarm d.

This arm d, at one end, pivots upon a spring-standard, a, fixed to the frame a.

Ar, its other end, the spring-arm d is jointed to a cylindrical hammer-head, e, which is capable of rising and falling within a corresponding cylindrical guide, ax, forming pan. of the standard a.

At the upper end of the hammer-head e, a piston is formed, which works in a corresponding cylinder at the top of the standard a, and the space enclosed under this pistou communicates with an air-passage fitted with a valve, which is worked by the descending-rod f.

All these parts are not shown in any great detail i the drawings, because they are not, in themselves, new, and they form no part of the present invention.

Their action is as follows:

As the axis b revolves, the eeccntrio b gives a vibrating motion to the spring-arm d, and the hammerhead e is thus worked-up and down in its guide, striking a blow upon the anvil g at each reciprocation, and during this time air is alternately received into and expelled from the space underneath the piston, upon the hammer-head.

When it is desired to prevent the hammer striking upon the anvil, the air-valve, which allows the ingress and egress of air, as above explained, is closed, and the airv being trapped underneath the piston, prevents the descent ofthe hammer-head, the spring-'arm'd and the spring-standard c then bending under the action of *be eccentric b.

The anvil g has set into it two steel dies, gl and g', which are shown seperately in the Figures 4 and the Figures 5 respectivelys and also in Figure 6, which is a side view of the hammer-head and anvil.` l

One of the des'g gf has upon it anincline ortaper corresponding with the face of the nail, and th'e other an incline or taper corresponding with the side of the nail. Y

The hammerfheadalso carries two sponding in form to the dies g g, them respectively.

h h' are two blocks, bolted to the table of theframe a, and holding, in a recess between them, the axis which has a rectangular notch, k', formed in' it, from end to end; and into this notch the nail-rod is received,

steel dies, correand wcrlclng with and it is locked in a clip, k', at the front end of A' axis, by the locking-screw kzx.

k k are pulleys on the axis 1c. Around them two cords pass, one to a spring, l, fend- 'ing constantlyto keep the axis I: with the notch k* uppermost in the position in which Ait is represented in the drawing, and with a projection at lcX upon-lt, -restin against a stop on the block h, whilst the other co passes to a lever, m., having a spring, n, attached to it, and this spring n, when iree to act, overpowers the spring l, turning the axis k to the right hand.

m. is a truck ofthe lever m, which the spring n, when the machine is at work, keeps in ontact with the cam o.

The axis of this cam is driven by a spur-wheel, of, upon it, gearing with a pinion, b, of half the size, upon the axis b. Thus it will bc seen that the action of the com o is to partially rotate the axis k first one way and then the other, between the successivo blows of the hammer, and the parts are su adios-ted that the axis k may maire a quarter rotation. This partial rotation carries the nail-bar from one pair of dies of the anvil and hammer to the other, and, at the same time, it

turns the baror quarter round between the blows, and in this way the rod is pointed.

The pointed bar is removed from the machine, and the pointed end being shorn olf, forms the nail required.

p is n treadle, connected by a link with the lever q, which springs q q' tend constantly m draw to its highest position, or that in which tbe drawing represents it; and this position it oocupieewhen the action of the machine is stopped.

Atthis time it will he seen that a rod, r, jointed to the end of the lever q, supports the pin n on the'leyer n, and prevents the spring n acting through the lever and oord on the axis k, which consequently remains stationary. But when the trjeadle. and lever q are depressed, the rod r is also carried' own until the ineline at its upper end comes opposite the pin es', and' the lever m and spring are free to operate.

When the tleadie p is depressed, the arm q on the axis of the lever q,`by means of the rod j; opens thevalve, and admits air to and from the cylinder ax, so as to allow the hammer to operate.

The lever q, when drawn down by the treadie, gives motion to the claw s, and in descending, the upper portion of said claw comes in contact with the screw kx, and turns it, so as to tighten it upon the properlyheated bar, which has been put into the notch in the axis k, and so the bar is held whilst itis being forged. Similarly, when the lever q rises, the lower portion of the claw s,at the proper time, comes in contact with the screw kx, and partly turns it in the opposite direction, and the nail-rod is released, so that it may be ref moved from the machine, and another substituted.

4The clip k is able to move a short distance longitu- Jdinally, in relation to theraxiak, which carries it so 'that the nail-bar may be more free to draw out, or len hen under the blows of the hammer.

o studs, kx'x kxx, fixed in the end of the axis, support and serve as guides -for the clip-piece k', and springs upon these studs press it toward the These springs, however, yield somewhht to the lengthening ofthe nail-red under thehammer.

t is a support, to uide the workman in placing the nailbars in the mac ine.

w is a pusher, connected with the .lever q, which, when the lever q is allowed to rise to stop the forgin of the nail-bar, acts' on a projection upon the clip so fntoturn itandtheaxiskintpapoas, sition suitable to admit of tb'e removal of the forged 4 nail-rod, and the introduction of a esh rod into the machine.
