NAIL-ASSORTING MACHINE.

SPECIFICATION forming part of Letters Patent No. 541,481, dated June 25, 1895.

Application led November 30, 1892. Serial No. 453,642. (No model.)

horizontally, and from those pools the nails are taken by litters and cast laterally point first into chutes, the side of the pool at its upper end having lugs against which the ends' of the nails bear, the point of each nail first passing one of said'lugs leaving the point end free to drop to the right or left and enter the chute prepared to receive it.

In this present invention each pool has at its opposite ends a chute, so that a nail raised from the pool will be cast into one or the other of said chutes head first, it entering one or the other of said chutes according to the position of the head.

Figure lis a top or plan view of a sufficient portion of a nail-assorting device to enable my invention to be understood. Fig. 2 is a section in the line oc. Fig.'3 is a section in the line A is a suitable upright or bar on which is secured a block B having at its upper end a hopper B on which headless nails are thrown in bulk. In this bar slides an elevator B2, actuated by, as herein shown, a sector lever B3, the teeth of which engage teeth at the shank of the elevator, and as the elevator rises it lifts a nail and the latter slides therefrom laterally into the pool a formed in a suitable block or bar C.

The parts so far described are substantially as in said Letters Patent, the pools being a little longer than the nails being assorted.

At the ends of the pool I have provided chutes b, c, into one or the other of which the nails taken from the pool will be cast or discharged. Preferably these chutes will be in the bar C, and they may join in a common and resting on a spring elocated between said cross-bar and the balancing kpost carrier f2 kept seated, as herein shown, on the slide B2 by fingers f3.

In operation it will be supposed that a nail is lying in the pool, and that the litters and balancing post are fully depressed. In this condition the slide B2 will be lifted and the carrier f2 and cross-bar e2 will rise in unison, the ends of the litters taking up with them a nail; but as soon as the cross head c2 is arrested in its ascent, as shown in 3, the balancing post in its further upward movement travels beyond the upper ends of the litters e, e and lifts the nail, as in Fig. 3, the head end of the nail, however, keeping its bearing on the end of one lifter, and when the balancing post has been raised sufficiently to so position the nail that gravity may assume control of it, then the nail will slide headforemost olf the balancing post and the lifter on which it then rests, and will drop into a chute.

In Fig. 3, the nail will go into chute c. In the patent referred toa nail when lifted from the pool by the fingers h, h, was acted upon This invention is not limited to the exact shape of actuating devices for the litt-ers and balancing post.

The devices shown may be duplicated side by sidev as provided for in the said patent.

Having described my invention, what I claim, and desire to secure by Letters Patent, 1S'- 1. In a nail assorting machine of the class having a pool into which the nails are deliv-` ered in bulk, the combination of a chute at each end of such pool, and a lifter adjacent to each chute, with a balancing post interposed between snch litters, movable with them, and having,r a further movement above the upper ends of said litters after the litters have reached the limit of their upward movement, to raise the nail from off the litters and permit it to drop olt` from it head foremost, by gravity, into one or the other of the chutes, substantially as described.

2. In a nail asserting machine of the class having a pool into which the nails are delivered in bulk, the combination of a chute at each end of such pool, and a litter adjacent to each chute, with a balancing post interposed between such litters, independent carriers for the litters andthe balancing post, means to lift both carriers simultaneously, and means to arrest the ascent of the litters carrier while the balancing post carrier proceeds farther upward and raises the balancing post above the litters, whereby a nail is raised by the litters and balancing post and thereafter raised off the litters by the balancing post and permitted to fall by gravity head foremost into that one of the chutes next the head end of the nail,substantially as described.

In testimony whereof I have signed my name to this specification in the presence ot' two subscribing witnesses.

CHARLES W. GLDDEN.
