  • Patent number: 4189062
    Abstract: A dispenser for split retaining rings includes a base, a bracket mounted on the base, a ring-retaining rail pivotably mounted to the bracket and a guide passage for a ring-removal tool. Lateral displacement of the rail is prevented by maintaining opposite sides of the rail in contact with stationary surfaces. The base is formed of a single piece of formed sheet metal and includes a bracket supporting platform and folded portions which prevent sagging of the platform. Frictional wear of the platform is prevented by a wear plate mounted thereatop. The ring-retaining portion of the rail is designed to accommodate a wide variety of retaining rings, including rings with and without a center prong. The dispenser is assembled at the time of manufacture with the rail permanently disposed with proper clearance above the guide passage.
