LINK FOR'CHAIN-S.

SPECIFICATION forming part of Letters Patent No. 544,759, dated August 20,1895.

Application filed ay 25, 1895- Be it known that 1, WILLIAM H. EIsENHART,

of York, in the county of York and State of Pennsylvania, have invented certain new and useful Improvements in Links for Chains; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part of this specification, and to the letters of reference marked thereon.

This invention has for its object to provide a link for chains which shall be simple, strong, and capable of being manufactured by automatic machinery, when so desired.

The invention consists in certain novel details of construction and combinations and arrangements of parts, all as will be now described, and pointed out particularly in the appended claims.

Referring to the accompanying drawings, Figure 1 is a perspective view of a link made in accordance with my invention. Figs. 2 and 3 are similar views of slightly-modified forms. v

Like letters of reference in the several figures indicate the same parts.

In carrying out my invention each link is formed by a single rod or bar of metal, which, starting from a central point is extended in both directions, the ends reflexed, and one end formed into an eye or loop which embraces the opposite end and central portion of the bar or rod.

Referring specifically now to Fig. 1, it will be seen that the barAhas its ends bent back or refiexed, forming the loop ends B B of thelink, one end being formed into an eye or loop 0, embracing the opposite end and central portion of the bar. In this preferred construction, Fig. 1, the ends of the bar are bent back on opposite sides or in opposite directions and the central portion of the bar is bent diagonally of the link, forming in effect a figure 8. The end D of the bar extends beyond the loop, and is again reflexed and passed through the loop in theform of a hook. With the parts Serial No. 550,711. (No od l.)

in this position, the eye is tightened and the whole constitutes a most efficient chain-link. It is not essential, however, that the end D should extend outside of the eye, but it may extend directly through the eye, as shown in Fig. 2, where the hook end D turns out in-- stead of in.

doubled back and the other end brought back and given a turn around the central portion and opposite end, forming the eye complete.

The manufacture may be carried out by hand or by automatic machinery, such as would at once occur to those skilled in the art of chain manufacture. I

Havingthus described my invention, what I claim as new is- 1. A chain link formed of a rod or bar of metal having the ends refiexed and one end formed into an eye or loop embracing the cen tral portion and opposite end of the bar; substantially as described.

2. A chain link formed of a rod or bar of metal having the ends reflexed in opposite directions, and one end formed into an eye or loop embracing the central portion and opposite end of the bar; substantially as described.

3. A chain link formed of a rod or bar of metal having the ends reflexed, one end formed into a hook and the opposite end formed into an eye embracing the hook and central portion of the bar; substantially as described.
