JOHN WILLS, OF KEESEVILLE, NEW YORK.

MACHINE FOR FINISHING HORSESHOE-NAIL BLANKS.

SPECIFICATION forming part of Letters Patent No. 250,863, dated December 13, 1881.

Application filed July 8, 1881. (No model.) 7

To all whom it may concern:

Be it known that I, JOHN B. W1LLs, of Keeseville, in the county of Essex and State of New York, have invented certain new and useful Improvements in Machines for Making Horseshoe-Nails; and 1 do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to machines for finishing horseshoe-nails; and it consists in the construction and arrangement of parts, as hereinafter more fully described and claimed.

In the annexed drawings, which fully illustrate the invention, Figure l is a top view of my improved machine. Fig. 2 is a vertical side elevation of the same with driving wheel removed. Fig. 3 is a section on the line m 00. Fig. 4 is a section on the line 3 Fig. 5 is a view of the inner face of driving-wheel, showing attached cam. Fig. 6 is a cross-section of the machine on the line 2 z, and Fig. 7 is a top and side view of the trimming-die.

' supports the carrier-wheels BB and other operative parts. The wheels B B are provided with a rim or flange, b, that affords a support for the endless feed-chain O, which also passes the horseshoenails.

over or around the pivoted flanged guides D D.

The feed-chain O is composed of suitable links pivoted together in any convenient manner, each link being provided on its upper surface with an inclined notch, c, and on its outer edge with a double inclined or beveled notch, 0'. The notches 0 form a ratchet for engagement with the pawl E, by which the chain is fed, and the notches c are for the reception of The feed-pawl E is attached to the upper part of a lever, E, which is pivoted to the bar a. This lever is provided with a friction-roller, e, and is operated at intervals by the contact with said roller of a cam, e, on the driving-wheel E The driving-wheel E is keyed to the end of a shaft, F, that carries a cam, G, and eccentrics H I. The cam Gr engages at intervals with a roller, d, in the end of a lever, J, which is mounted at its opposite end on a rock-shaft, K.

Beneath the lever J, extending in the opposite direction, is a lever, L, having a roller,f, against which the lever J presses. The lever L is mounted on a rock-shaft, M, arranged beneath the wheel B. This shaft M is provided with an arm, g, the beveled end of which bears against a lug, h, on the anvil-block N, which is mounted on a rock-shaft, O, the arm g and lug It being held to a constant contact with each other by means of the downward pressure of the spring-rod i.

The anvil N carries a straightening-die, k, which is arranged opposite a die-roller, I, that is journaled in bearings in the end of the die stock or box P,which incloses the eccentric H on the shaft F.

In the die stock or box P are sliding blocks or bearings m m, upon which the eccentric H acts to impart an oscillating movement to the box P, and cause its roller 1 to roll downward in contact with the die 70, or with the nail held therein, thus straightening the latter.

It will be observed that the anvil N and die It recede through the movements of the rockshaft M and its, arm 9 when the stock I? and roller Z ascend after the nail is straightened. The stock I? is pivoted in a block or bearin g, a, secured to or forminga part of the rock-shaftK.

On the shaftKis loosely journaled a slotted block or hearing, 0, through which passes the shank of the die-stock Q, which incloses the eccentric I on the driving-shaft F. It will thus be seen that the stock Q has both a reciproeating and an oscillating movement. At the forward end of the stockQis journaledaroller, p, which acts in connection with a stationary die, q, arranged opposite on a standard, a, to flatten the point of the nail. The stock Q is also provided at its forward end with a projection that carries a die, 1, that holds the point of the nail against the trimming die or knife s. This knife is adjustably supported in the standard a, so as to be readily arranged in any desired position.

Beneath the lever L is a block, it, that rests on a spring, u,which serves to force the levers J L back after they have turned the rock-shafts K M inward. The pawl E, as soon as released from the pressure of the cam c acting on the roller e, is forced back by means of a spring, 22. In feeding the chain 0 forward the pawl E is held to its engagement with the ratchet O on said chain by means of a guide-yoke, to, through which the pawl passes.

The nails to be finished having been placed in the notches c of the feed-chain C, it will be seen that at each revolution of the drivingwheel E the pawlE, engaging with the ratchet c, is caused to feed the chain forward, thus bringing the nails in contact with the dies 75 q 8, while the simultaneous movement of the rock-shafts K M O, actuated by the cam G through the levers J L and arm g, as well as the movements imparted to the stocks P Q by the eccentrics E1 on the shaft F, cause the dies 1 r to coact with the said dies 70 q s in giving the necessary finish to the nails.

The pawl-lever E may be operated by hand, if desired, and the shaft F rotated by any suitable power.

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

1. In a horseshoe-nail machine, the combination of the flanged wheels B B, guides D D, carrier-chain 0, consisting of pivoted links having notches c c, and the pawl E, attached to lever E, substantially as shown and described.

2. The combination of the frame A, flanged wheels B B, guides D D, ratcheted feedchain 0, lever E, carrying pawl E and roller 0, and shaft F, carrying wheel E provided with cam e, substantially as and for the purpose described.

3. The combination of the frame A, shaft F, having cam G and eccentrics H I, die-stocks P Q, provided with dies, rock-shafts K M O, levers J L, anvil N, and suitable spring-connections, substantially as shown an d described.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in presence of two witnesses.

JOHN BOMAN YVILLS.
