Abstract
Abstract A composite sealing device is formed by molding a resilient ring on a coined portion of the inner diameter of a washer. A mechanical bond is formed by the ring material extending through holes at the outer periphery of the coined portion of the washer. The holes are of such diameter as to permit cold flow of metal into the holes from the coined portion of the washer without completely filling the void of the holes.

Claim 1
Independent Claim
129 words
A composite sealing device comprising: 1. a malleable washer having an annular main body; i. a central opening defined by a continuous inner circumferential peripheral surface; ii. a plurality of apertures disposed in said washer and spaced about said central opening; iii. a portion of said main body being of reduced axial thickness and extending radially outwardly from said central opening and into each of said apertures to form jagged edge portions along each interface between said apertures and said portion of reduced axial thickness; and 2. a resilient sealing ring disposed on and surrounding said portion of reduced axial thickness and extending through said plurality of apertures, wherein said resilient sealing ring is in engagement with and retained by said jagged edge portions of said plurality of apertures.
