ALVEUS J. CLEMMONS, OF ABERDEEN, MISSISSIPPI.

IMPROVEMENT lN CHAIN-MACHINES.

Specification forming part of Letters Patent No. 121,849, dated December 12, 1871.

To all whom it may concern:

Be it known that I, ALvEUs J. OLEMMoNs, of Aberdeen, Monroe county, Mississippi, have invented an Improved Chain-Machine, of which the following is a specification:

Figure 1 is a top view Fig. 2, a side elevation, illustrating the process of bending the eyes of the links; Fig. 3, a perspective view, showing the parts disconnected; and Fig. 4 is a perspective view of the link.

This invention relates to a machine for forming links of staple-shape or open at one end, and having eyes at the extremities of the piece of metal forming each link, such links being more especially designed for well-chains.

Referring to the drawing, a is a bench, to whose top is secured a metal plate, I), from which spring parallel lugs 0, running lengthwise of the bench and placed far enough apart to receive between them a lever, r1, pivoted at one end to the bench. To the under side of the lever 61 is fastened a hook, e, and to its upper side a leaf, f, through whose eye is passed, crosswise ot the bench a, a pin, g, that serves as the pivot for a clevis, h, whose legs extend one to each side of the lever d, and have pins is projecting from their outer sides near their ends, said pins being, when the clevis is turned backward a little in rear of the grooves i in the insides of the lugs 0, formed to receive the pieces of iron which make the links. To the under side of the bench a is hinged a lever, 1, having a hook, 111, which connects with the hook e. To lay the blanks across the tops of the lugs c the parts have to be disconnected, as shown in Fig. 3. The upper lever is then turned down upon the blanks and the clevis h turned back, as shown in Fig. 1. Connecting the hooks e and m, the force of both levers is available for bending the blanks into links between the lugs 0, the links during the process entering the grooves z. \Vhen fully bent the ends of the links extend above the lugs 0. By turning forward the clevis h, as shown in Fig. 2, the pins k are made to form the eyes 12 at the extremities ofthe links.

I claim as my invention The combination of the bench a, lever d, lugs c, and clevis h having the pins k, all arranged as specified.
