Abstract
A seal for use in sealing an annular opening between a stationary member and a rotating cylinder telescopically arranged with the stationary member, the seal comprising a series of partially overlapping members circumscribing the cylinder adjacent the stationary member and closing the annular opening. The seal comprises a series of self-biasing leaf members attached to the stationary member and being biased into sealing engagement with the rotating member and a series of blanket members positioned adjacent the seal members to prevent leakage from the gaps between adjacent leaf members to substantially seal the annular opening between the rotating and stationary members.
