Abstract
A retaining device to secure a socket to an anvil including an O-ring, an integral projection extending inwardly from the O-ring, and an insert secured at or near a far end of the integral projection. The insert may be made from a non-metallic high modulus material that can compress up to 50% of its original diameter without breaking. The insert may also include a socket wear indicator that consists, for example, of a raised ridge located within a recess on the side of the insert. The raised ridge, if crushed at the juxtaposition between the socket and the anvil, provide an early indication that the socket's drive aperture is worn and that the socket should be replaced.
Claims12
A one-piece retaining ring that is adapted for securing a socket to an anvil having a transverse through-hole, the socket having a drive aperture, an annular groove about its periphery and a cross-bore that aligns with the anvil's transverse through-hole when the anvil is inserted into the socket's drive aperture, comprising:
- an O-ring;
- a projection formed integrally with and extending inwardly from the O-ring;
- an insert;
- means for securing the insert at or near an end of the projection;
- and
- a socket wear indicator that is located on a side of the insert and is positioned within the juxtaposition between the socket's cross-bore and the anvil's transverse through-hole to present a crush mark that visually indicates when the socket's drive aperture is worn to the point that the socket fits loosely on the anvil and should be replaced, the socket wear indicator formed from a raised ridge that extends outward from a recess on the side of the insert.
