Abstract
Abstract This invention provides a pipe-coupling arrangement that includes a gasket around each of the pipes to be connected, the gaskets having outwardly tapered surfaces engaged by members outwardly of them, with a provision being made for compressing the gaskets to wedge them against the surfaces of the pipes. One of the gaskets may include an outwardly tapered portion for sealing against a surrounding part when the gaskets are compressed, or a separate O-ring may be used for this purpose. The inclusion of sealed telescoping sleeves provides for an expansion coupling.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
287 words
In combination with a first tubular member and a second tubular member having adjacent ends, a device for sealingly interconnecting said adjacent ends comprising annular means circumscribing said adjacent ends, a first gasket circumscribing said first tubular member, said first gasket having an inner substantially cylindrical surface substantially complementarily engaging the outer surface of said first tubular member, a second gasket circumscribing said second tubular member, said second gasket having an inner substantially cylindrical surface substantially complementarily engaging the outer surface of said second tubular member, said annular means being interposed between and engaging the adjacent ends of said gaskets, said first gasket having a surface remote from said end thereof inclined radially and axially inwardly relative to said first tubular member, said second gasket having a surface remote from said end thereof inclined radially and axially inwardly relative to said second tubular member, a first annular element adjacent said first gasket, said first annular element having a surface inclined radially and axially inwardly relative to said first tubular member and engaging said remote surface of said first gasket, a second annular element adjacent said second gasket, said second annular element having a surface inclined radially and axially inwardly relative to said second tubular member and engaging said remote surface of said second gasket, means for providing a seal between said first and second annular elements, and means for biasing said first and second annular elements relatively toward said annular means for urging said ends of said gaskets against said annular means, and reacting through said remote surfaces of said gaskets to compress said inner surface of each of said gaskets inwardly against the periphery of the tubular member which it circumscribes for effecting a seal therewith.
Claim 2
Dependent Claim
287 words
In combination with a first tubular member and a second tubular member having adjacent ends, a device for sealingly interconnecting said adjacent ends comprising annular means circumscribing said adjacent ends, a first gasket circumscribing said first tubular member, said first gasket having an inner substantially cylindrical surface substantially complementarily engaging the outer surface of said first tubular member, a second gasket circumscribing said second tubular member, said second gasket having an inner substantially cylindrical surface substantially complementarily engaging the outer surface of said second tubular member, said annular means being interposed between and engaging the adjacent ends of said gaskets, said first gasket having a surface remote from said end thereof inclined radially and axially inwardly relative to said first tubular member, said second gasket having a surface remote from said end thereof inclined radially and axially inwardly relative to said second tubular member, a first annular element adjacent said first gasket, said first annular element having a surface inclined radially and axially inwardly relative to said first tubular member and engaging said remote surface of said first gasket, a second annular element adjacent said second gasket, said second annular element having a surface inclined radially and axially inwardly relative to said second tubular member and engaging said remote surface of said second gasket, means for providing a seal between said first and second annular elements, and means for biasing said first and second annular elements relatively toward said annular means for urging said ends of said gaskets against said annular means, and reacting through said remote surfaces of said gaskets to compress said inner surface of each of said gaskets inwardly against the periphery of the tubular member which it circumscribes for effecting a seal therewith.
Claim 3
Dependent Claim
43 words
A device as recited in claim 1 in which said annular means includes a central cylindrical portion overlapping the adjacent ends of said tubular members, and a washer at either end of said cylindrical portion, said washers engaging said ends of said gaskets.
Claim 4
Dependent Claim
55 words
A device as recited in claim 1 in which said means for biasing said first and second annular elements relatively toward said annular means includes an outwardly projecting flange associated with either of said annular elements, and threaded means interconnecting said flanges for moving said flanges toward each other upon rotation of said threaded means.
Claim 5
Dependent Claim
53 words
A device as recited in claim 2 in which at least one said annular elements includes an extension overlapping said annular means, said means for providing a seal between said first and second annular elements including a seal interposed between said annular means and either of the overlapping portions of said annular members.
Claim 6
Dependent Claim
49 words
A device as recited in claim 4 in which said annular means is cylindrical, said extensions of said annular elements are cylindrical, and in which each of said seals is an O-ring, said annular means having a circumferential groove in the outer surface thereof for each of said O-ring.
