repair-link

Century Dictionary and Cyclopedia

1. n. In mech., a chain-link so constructed that it can readily be substituted for a broken link. In round-link chains it is usually made of half-sections of a link formed by a plane which passes through its long and short axes, the link being open on the long side for a length equal to the thickness of the iron of which the links are made. These two halves are hooked to the adjoining links so that the opening of each half comes against the continuous side of the other, and when in place the two halves are riveted together. In fiat or roller-chains, the two pins are riveted to one side or cheek, and the other cheek is held in position after the repair-link is in place by cotters or spring loops of wire.
