IMPROVEMENT IN NAIL-DELIVERING MACHINES.

' Specification forming part of Letters Patent No. 145,755, dated December 23,1873; application led October 29, 1873. Y

To all whom it may concern:

Be it known that I, SrLAs S. PUTNAM, of Boston, in the county of Suffolk and State of Massachusetts, have invented an improved machine for receiving, turning, and deliver-I ing forged or partially-made horseshoe-nails to other machinery for afterward operating upon them, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings making part of this specification, in which- Figure l is a front elevation of my improved machine. Fig. 2 is a side elevation of the same. Fig. 3 is a vertical section on the line x x of Fig. 2. Fig. et is a section on the line y y of Fig. l.

Forged or partially-made horseshoe-nails have been delivered to machinery, for finishing or otherwise operating upon them, by a carrier-wheel which was provided with compartments to receive the nails and jaws or nippers to hold them from dropping out during the revolution of the wheel, the jaws being opened at the required times to release the nails and allow them to drop out.

This invention has for its object to provide a cheaper, more effective, and less complicated mechanism than that above described, and consists in the combination of a carrier-wheel provided with one or more boxes or compartments for receiving the nails, which are prevented from dropping out until they arrive in the proper position, with conductors and a ring or guard which surrounds the carrier-wheel, the latter being partially rotated alternately in opposite directions, or revolved intermittingly in one direction, as preferred, while the rim or periphery of the carrier-wheel intercepts the nail and retains it within the conductor until the box or compartment arrives beneath it.

To enable others skilled in the art to understand and use my invention, I will proceed to describe the manner in which I have carried it out.

In the said drawings, A represents the bed of the machine, from which rise the supports a b of a circular frame or ring, B, at the back of which are two cross-bars, c d, and at the point where these bars unite is a long bearing, e, in which is supported a shaft, f, to one end of which is secured a gear, C, and at the opposite end a carrierwheel, D, which is incloscd within the ring B, on the inside of which is a iiange, 5, as seen in Fig. 4. Extending radially from the hub to the periphery of the wheel D, and connecting them together, are two boxes or compartments, g g, which are open at their outer ends, and are formed to receive the nails as they drop point or head down singly from a conductor, E, at the top of the ring B, the nail in the conductor passing through a notch or aperture, 6, in the ring, and resting on the periphery of the wheel, asseen in Fig. 3, and it is thus retained within the conductor until one of the compartments g is brought under it, when it drops therein and is carried round by the revolution of the weeel until it arrives in a position over a notch, 8, in the bottom of the ring, and diametrically opposite to the notch 6, when it drops out of the compartment into a conductor, G, by which it is delivered to other machinery for finishing or otherwise operating upon it; and it will be seen that the ring B serves as a guard to prevent the nail from dropping out as the carrierwheel is revolved, thus avoiding the necessity of employing jaws or nippers to hold the nail, as heretofore, and rendering the machine less complicated and more certain in its action, and also reducing its cost. The half-revolution of the carrier-wheel serves to turn the nail so that it is dropped into the lower conductor Gr, with its head in a position exactly the reverse of that which it occupied when in the upper conductor E. The carrienwheel is rotated half-way round, first in one direction, and then in the other, so as to bring the compartments g g alternately beneath the conductor E to receive a nail, by means of a toothed segment, t', at the end of a lever, H, which engages with the gear C at the end of the shaft f, each compartment being momentarily arrested previous to the direction of its' motion being reversed, on its arrival beneath the conductor E, or over the conductor Gr, which allows sufficient time for 'the nail to drop into or out of its compartment. The lever H is pivoted upon a stud projecting from the vertical bar c, and its lower arm is provided with a slot, 7c, in which ts a crank-pin, l, projecting from the face of a disk, I, secured to the inner end of a shaft, m, which has its bearing in a standard, K, and carries at its outer end a Wheel, L, by revolving which the lever H is vibrated to actuate the carrier-Wheel, as required.

'Instead of partially rotating the carrier- Wheel alternately in opposite directions, it may be revolved intermittingly in one direction by a ratchet-Wheel and .paWl, or other suitable device, and, instead of employing two boxes or compartments, g, as shown, one only, or a series of three or more, may be used, if preferred, in which latter case the carrierwheel would be revolved intermittingly in one direction, the amount of each movement being made to correspond With the distance between the compartments.
