ABSTRACT OF THE DISCLOSURE
A chain link having a pair of curved extremities and
being generally in the shape of an elongated loop. The loop
defines two sides which converge towards the middle of
the link where the two sides are rigidly joined together,
as by a weld, thereby forming a pair of interior spaces
progressively narrowing towards the middle. Such link is
adapted for use in alternation with pin links in a chain
designed to remove waste material in a livestock enclosure.
A method of making the link is further disclosed.
