Patent number: 5875536Abstract: An apparatus for installing a snap ring comprises an inner press assembly which is spring biased downwardly from an upper press assembly. The inner press assembly includes a plurality of arms having first ends having an abutment surface adjacent a notch. During installation of the snap ring, the upper press assembly and inner press assembly move toward a component which receives the snap ring, such that the first ends of the arms abut the snap ring. The snap ring is thus moved downwardly into the component. If the snap ring expands radially outwardly into the snap ring groove, the abutment moves past the snap ring and the notches receive the snap ring. If the snap ring does not expand sufficiently radially outwardly into the snap ring groove, the abutment surface of the arms contacts the snap ring, thereby resisting downward movement of the inner press assembly. There is then relative axial movement between the inner press assembly and the upper press assembly.Type: GrantFiled: March 14, 1997Date of Patent: March 2, 1999Assignee: Cobra Machine Tool Co., Inc.Inventor: Frank N.
