Links or coupling devices of the general form of a chain-link which are designed to replace broken links or connect chains or parts of chains without heating or welding. These links should be capable of receiving two chain-links and furnishing bearings for the same, one at each end of the detachable link.
(1) Note. This subclass does not include hooks or coupling members or devices which are especially designed for other purposes and are classifiable elsewhere, as whiffletree-connectors, clevises, etc. Lap links or rings designed for general use and which answer the above requirements will be included in this subclass. For links for connecting sprocket-chains, see Class 474, Endless Belt Power Transmission Systems or Components, particularly subclasses 202+ for positive drive power transmission belts and links used in such belts.
