Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
183 words
A chain link for a product capturing chain, comprising: a flat base portion having front and back surfaces, first and second ends, and leading and trailing edges; hinge eyes projecting from said leading and trailing edges for connecting said link to the other similar links; at least one guide shoe projecting from said back surface for supporting said link on a track; a resilient, hollow, tubular gripping member approximately the same length as said flat base portion, having first and second ends and said inner and outer surfaces and including a flattened outer surface portion contacting said front surface of said flattened base; first and second opposed retaining lips integral with said flat base portion and projecting from said first and second ends, each of said lips including a first portion substantially perpendicular to said flat base and a second portion substantially parallel to said flat base opposite said front surface, the opposed retaining lips each being wrapped around one of the ends of said hollow, tubular gripping member and projecting inside said gripping member for retaining it on said flat base portion.
Claim 2
Dependent Claim

A chain link for a product capturing chain, comprising: a flat base portion having front and back surfaces, first and second ends, and leading and trailing edges; hinge eyes projecting from said leading and trailing edges for connecting said link to the other similar links; at least one guide shoe projecting from said back surface for supporting said link on a track; a resilient, hollow, tubular gripping member approximately the same length as said flat base portion, having first and second ends and said inner and outer surfaces and including a flattened outer surface portion contacting said front surface of said flattened base; first and second opposed retaining lips integral with said flat base portion and projecting from said first and second ends, each of said lips including a first portion substantially perpendicular to said flat base and a second portion substantially parallel to said flat base opposite said front surface, the opposed retaining lips each being wrapped around one of the ends of said hollow, tubular gripping member and projecting inside said gripping member for retaining it on said flat base portion.
Claim 3
Dependent Claim
69 words
A chain link as recited in claim 1, wherein the inner surface of said resilient gripping member defines a flattened portion opposite the flattened portion on its outer surface, said flattened portion on the inner surface of said gripping member having approximately the same width as said opposed lips, so that said lips contact said flattened inner surface portion for retaining said resilient gripping member on said flat base.
Claim 4
Dependent Claim
53 words
A chain link as recited in claim 2, wherein each of said opposed lips includes forward and rear edges, each of said edges defining a rounded indentation at the intersection of said first and second portions of its respective lip, so as to provide a smooth edge for contacting said resilient gripping member.
