MA'CHiNE FOR MARKING HORSESHOE-NAILS.

SPECIFICATION forming part of Letters Patent No. 320,423, dated June 16, 1885.

Application filed February 25, 1885.

To all whom it may concern.-

Be it known that I, CHARLES WELLINGTON WOODFORD, of Essex, in the county of Essex and State of New York, have invented a certain new and useful Improvement in Horseshoe-N ailFinishin g Machines and I do hereby declare that the following is a full, clear, and exact description of the same.

My invention consists in the combination, with a ring carrying in pockets the heads of horseshoe-nails or nail-blanks, and intermittently rotated, of a tripping device for raising the heads of such nail-blanks or nails above the surface of the ring, and a reciprocating die or dies for impressing upon the face of the head of such nail-blank or nail any device which may be chosen to identify the nails made by any firm or company.

For full comprehension of the invention reference must be had to the annexed drawings, in which Figure 1 is a part plan view of upper side of ring and marking mechanism Fig. 2, a side View of same, and Fig. 3 a front view of tripping device.

Similar letters of reference indicate like parts.

Only such parts of the machine as relate particularly to the present invention are shown fully, the others, if indicated at all, being simply in outline.

A is the horizontal revolving ring, having its periphery formed of a series of ratchetteeth, and intermittently rotated by means such as apawl actuated by a bellcrank lever, or in any of the usual and well-known methods. In pockets (0, formed on the innerperiphcry of this wheel, are carried the nail-blanks or nails.

B is the stationary ring.

In the drawings my invention is shown in connection with the head or guide 0, carrying the clipping or shearing dies for pointing the nail, this being extended so as to hold a die, I), on the face of which is recessed or cut in relief the mark desired to be placed on the nail.

To the guide or traveler O is secured at any desired point a projecting piece, E, having a flat upper surface and an obliquely-cut end, which, as the guide moves forward, first (No model.)

raises and then holds up the free end of a hinged tripping arm or lever, F, which rests usually upon a suitably-placed pin or support,

f. The lever F thus acted upon raises the nail which is in the ring A, immediately opposite to the die D, until the head is above the level of the top of the ring, thus exposing the face to the action of the die and holding it in position to receive its impact, a stationary die, G, secured to the inner ring, 13, holding the nail during such operation. With the next movement of the ring the nail is released from the tripping-lever F, drops down to its former level in the ring, and is carried round until removed from the ring by any ordinary means for the purpose. The backward movement of the guide 0 and projecting piece E allows the tripping-lever F to drop to its normal level.

It must be understood that, although I have shown my invention as operating in connection with and after the pointing and finishing mechanism, I do not confine myself to this, as it may be situated anywhere on the ring, and the operation of marking the die be performed even before the nail-blank is reduced. Again, the die G within the ring may be the reciprocating marking one and the die D stationary; or both may be arranged to reciprocate, if desired.

.The tripping device shown is one which will be found "eryefl'ectivein producing the result desired; but it must be'understood that I do not confine myself to its precise details, as any equivalent means may be used for the purpose.

What I claim is as follows:

In a horseshoe-nail-finishing machine, the combination, with an intermittently-rotating ring carrying in pockets nail-blanks or nails, of a tripping device for raising and holding the heads of such nails above the surface of the ring, and a reciprocating die or dies for impressing the desired device on each nail-head, substantially as described.

CHARLES WELLINGTON WOODFORD.
