WILLIAM M. STONE AND HENRY DUNDAS, OF KEESEVILLE, NEW YORK.

DEVICE FOR SORTING HORSESHOE-NAILS.

SPECIFICATION forming part of Letters Patent No. 355,109, dated December 28, 1886.

Application filed November 5, 1886. Serial No. 218,052. (No model.)

To all whom it may concern:

Be it known that we, WILLIAM M. STONE and HENRY DUNDAS, both of Keeseville, in the counties of Essex and Clinton and State of New York, have invented a new and Improved Device for Sorting Horseshoe-Nails, of which the following is a full, clear, and exact description.

The object of our invention is to provide a new and improved device for sorting long and short horseshoe-nails rapidly and accurately.

The invention consists of a ring revolving on a block and provided with recesses, of an adjustable stationary cam attached to the said block, and of a bent arm for separating the nails and leading them to a discharge-opening in the block.

v The invention also consists of various parts and details, and combinations of the same, as

will be described hereinafter,and then pointed out in the claims. 7

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a'plan view of ourimprovement. Fig. 2 is an elevation of the same with part of the ring broken away. Fig. 3 is asectional side elevation of the same on the lines x w of Fig. 2. Fig. 4 is a side view of the same in part.

The circular stationary block A is provided with the annular recess B, in which is 'fitted the ring 0, having recesses D on its inner edge, which extend a short distance beyond the rim of the block A, having the recess E, forming a pocket, E. A cam, F, is held on the rim of the block A, and is vertically ad j ustable by a set-screw, G, and is provided with a rabbet, F, near the rim of the block A.

To the upper edge of the rim of the block A, near the pocket E, is attached the outwardlybent arm H, which curves downwardly and has its lower pointed end a short distance above the center of the cam F. A spring, J is held to the upper edge of the rim of the block, and extends toward the arm H and rests with its free end on the inner edge of the ring 0.

The operation'is as follows: The ring 0 is revolved on its bearing B in any suitable manner, either by hand or by power, in the direccesses D reach the recess E of the block A..

The heads of the nails I"rest on the ring 0, and thus support the nail. As soon as the nails I reach the cam F, then the short nails, which do not touch thecam F, remain in their vertical position and pass between the spring J and the arm H into the recess E, and drop out of the recesses D in the ring as soon as they reach the pocket E, the arm H operating as a cam to force them out. (See Figs. 2 and 3.) The rabbet Fin the cam F permits of setting the cam high enough, so that all the nails which are too long to pass over perpendicularly will be thrown out sufliciently to pass entirely clear of the arm H. The longer nails come with their lower ends in contact with the cam F, and are thrown into an inclined position, as shown in Fig. 4, and pass to the out side of the arm H, and remain in their support on the ring 0 by the action of the spring J. When the long nails have passed the arm H, they are then removed from the ring. Thus .it will be seen that all the short nails drop out of the ring 0 when coming to the pocket E, while the longer nails remainin the ring, and are thus separated from the short ones. The cam F can be raised or lowered, according to the length of the nails to be sorted.

Having thus fully described our invention, what we claim as new, and desire to secure by Letters Patent, is

1. The combination of a revolving ring having recesses for carrying nails, a block for supporting said ring and having a recess or pocket for the discharge of short nails, a cam for throwing the shanks of the long ones out of a perpendicular or vertical position, an arm acting as a cam to force the short ones out of the recesses in the ring, and a spring to retain the heads or necks of the long ones in position while passing the pocket provided for the discharge of the short ones, substantially as described.

2. The combination, with a revolving ring having recesses, of a block supporting the said ring and having a recess forming a pocket, an adjustable cam having a rabbet and held on the said block, a bent arm extending downwardly, and a spring to hold the short nail in place until it reaches the said pocket, substanrim of the block, and the spring J, fastened to tially as described. the block and extending along the upper end 3. The combination, with a revolving ring of the-rim of the block, in combination with having recesses, of a block supporting the said the ring 0, having the recesses D, substanr 5 5 ring, a cam,a bent arm extending downwardly, tially as described.

and a spring extending to the said arm to hold the nails in place, substantially as described.

4. The block A, provided with the recess B,

and the recess E, forming the pocket E, the Witnesses:

to vertically-adjustable cam F, having the rabbet CHARLES F. BERo,

F, the outwardly-bent arm H, secured to the GEO. -W. THOMPSON.
