Abstract: A conveyor chain for poultry processing is formed of injection molded regular links in serially connected relationship, and has at intervals a special link adapted to receive a threaded stud for a chicken carcass-supporting cone or other structure. The special link has a base portion which is of preferably the same configuration as the regular links. Above this, integrally molded with the base portion, is a platform with laterally outwardly extending flanges for stability against tilting. A threaded boss extends up from the platform and has a threaded internal bore extending vertically, to receive a threaded stud. The threaded boss comprises a relatively light plastic cylinder and has regularly extending buttresses stabilizing it on the platform. The special link is integrally formed by injection molding of a suitable material such as acetal, and is light in weight and profile.
