Abstract: A bowed external spring retaining ring of the E-shaped type includes flats at the leading and trailing ends of the ring. The flats form leading and trailing edges of the ring which are rounded on a concave side of the ring. The ring is formed by a punch which has an end face comprised of a concave portion and straight portions, the latter forming the flats on the ring.

Abstract: A bowed internal retaining ring comprises a middle tab and a pair of intermediate tabs projecting generally radially from the ring, said middle tab being flat and coplanar with a pair of flat end sections of the ring. The ring can be installed forwardly or backwardly without appreciably altering the performance of the ring.
Abstract: An applicator for installing a radially installed spring retaining ring into an external groove of a shaft comprises a ramp having a slot for receiving a groove shaft. The ramp also includes a pair of opposed side walls between which the rings travel. Each ring includes a pair of flats arranged to guidingly engage the side walls to prevent the ring from rotating as it advances along the ramp.
Abstract: An applicator for installing a retaining ring into an external groove of a workpiece comprises a floor having a slot for receiving a grooved workpiece. A pair of groove locators are rotatably mounted alongside the floor. The groove locators have forwardly converging side edges against which the rings engage as they are being pushed forwardly. Such engagement pushes the locators apart whereby forward free ends of the locators are displaced out of the workpiece groove by an advancing ring. The side edges are arranged to impose relatively small forces tending to close the ring, and to retain the ring in contact with the floor.
