Abstract
Abstract A mounting link plate for a link chain has a laterally projecting bridge secured to one of its longitudinal edges. The bridge is press-fit into a slot in a nonmetallic lug. The link and lug are then pivotally secured to a chain by pins and a pin link plate in a known manner so that the lug is located between the spaced connected link plates and projects away from the chain.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
246 words
An attachment for a link chain having a plurality of laterally spaced link plates pivotally interconnected at their ends to other laterally spaced link plates, said attachment comprising: a retaining link plate pivotally connected at its ends to certain of said laterally spaced link plates of said link chain: a mounting link plate pivotally connected at its ends to said retaining link plate and to said certain of said laterally spaced link plates of said link chain, said mounting link plate being laterally spaced from said retaining link plate; an arm on said mounting link plate projecting upwardly above an upper edge of Said link chain and laterally toward said retaining link plate; inwardly facing surfaces on said mounting link plate and said retaining link plate, respectively, partially defining a space between said mounting link plate and said retaining link plate; a lug in said space between said mounting link plate and said retaining link plate, said lug projecting upwardly above said upper edge of said link chain and having an aperture extending laterally therethrough, said arm on said mounting link plate being movably engaged in said aperture, whereby, the arm on said mounting link plate and the lug are moveable relative to each other for disassembly; and outwardly facing side surfaces on said lug engageable, respectively, with said inwardly facing surfaces of said mounting link plate and said retaining link plate to retain said lug between said mounting link plate and said retaining link plate.
Claim 2
Dependent Claim
