ABSTRACT:
An adjustable sealing device for sealing between rotatable drive shaft, such as a propeller drive shaft, and the aperture in a structure, such as the hull or bulkhead of a vessel, through which the shaft passes. The device is generally rigid and is comprised of an adapter ring, a slide ring, a diaphragm positioned between the adapter ring and the slide ring, a friction ring having one end positioned in the adapter ring and a seal surface engageable with the seal surface of a seal ring rotatable with the shaft, biasing means positioned between the slide ring and the friction ring for urging the seal surfaces together, and a spring cover acting as a seal redundant to the diaphragm.
