Abstract
Abstract A gasket seal for use in the sealing of conduits with telescoped ends, the conduits being subjected to high vacuum flow therethrough, which seal consists of a flexible plastic band around the outside conduit with a lip extending over and beyond the outside conduit which lip engages the inner conduit and has an outer clamp extending to a rim on the lip and engaged with the lip and in overlapped relation to the end of the outer conduit to squeeze the band into engagement with the outside conduit and the lip into engagement with the inner conduit, and thereby provide an airtight seal.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
212 words
In combination: a pair of conduits having telescoped ends in engagement and in which the outer conduit has an exterior circumferential surface with a terminal shoulder and the inner conduit has an exterior circumferential surface; a flexible endless elastomeric band having side margins; an interior shoulder between said side margins for engagement with the terminal shoulder; a lip extending along the inner conduit, and having an inwardly extending rim bounded by one of the side margins and said interior shoulder and having an interior surface engaging the circumferential surface of the inner conduit; said lip having an exteriorly disposed terminal rim portion spaced along the inner conduit in spaced relation beyond said shoulder; said band having an interior face extending from said interior shoulder for engagement with the circumferential surface of the outer conduit; and a circumferentially contractable clamping member having side margins and being circumferentially disposed on said band and positioned with one of said side margins of the clamping member in contact with said terminal rim portion, said clamping member being disposed inwardly of the side margins of the band in overlapped relation to said band at said shoulder and simultaneously clamping said band in engagement with said circumferential surfaces of said conduits on opposite sides of said interior shoulder.
Claim 2
Dependent Claim
212 words
In combination: a pair of conduits having telescoped ends in engagement and in which the outer conduit has an exterior circumferential surface with a terminal shoulder and the inner conduit has an exterior circumferential surface; a flexible endless elastomeric band having side margins; an interior shoulder between said side margins for engagement with the terminal shoulder; a lip extending along the inner conduit, and having an inwardly extending rim bounded by one of the side margins and said interior shoulder and having an interior surface engaging the circumferential surface of the inner conduit; said lip having an exteriorly disposed terminal rim portion spaced along the inner conduit in spaced relation beyond said shoulder; said band having an interior face extending from said interior shoulder for engagement with the circumferential surface of the outer conduit; and a circumferentially contractable clamping member having side margins and being circumferentially disposed on said band and positioned with one of said side margins of the clamping member in contact with said terminal rim portion, said clamping member being disposed inwardly of the side margins of the band in overlapped relation to said band at said shoulder and simultaneously clamping said band in engagement with said circumferential surfaces of said conduits on opposite sides of said interior shoulder.
Claim 3
Dependent Claim
24 words
The combination defined in claim 1 in which said band has an external positioning groove for said clamping member bounded by said terminal rim.
Claim 4
Dependent Claim
28 words
The combination defined in claim 1 in which said band has a roughened inner surface to aid in gripping the exterior circumferential surface of one of said conduits.
