Abstract
Abstract An apertured flange member with a beveled inner edge slidably disposed about a uniform cylindrical surface of a tubular member having an elongated axial bore and a circumferential recess immediately adjacent the tube''s end extremity in which recess a resilient sealing ring is seated, and means for moving the flange member toward a second body arrangement to produce a fluid-tight (liquid or gas) communication between the bore and an opening in an end extremity of the second body arrangement by the action of the beveled edge urging only a portion of the sealing ring beyond its seat and toward and contacting the second body arrangement, whereby the sealing ring is compressed into an inescapable cavity formed by the beveled edge of the flange and the circumferential recess.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
194 words
A semiflexible fluid-tight tube coupling device, comprising: a first tubular member having an elongated axial bore and a uniform outer cylindrical surface except for a first circumferential recess sealing ring seat substantially immediately adjacent an end extremity thereof; a second body arrangement including an opening in an end extremity thereof; a first resilient sealing ring seated in said circumferential recess; a first flange member having an aperture therethrough slidably disposed about said outer cylindrical surface, said flange member including a beveled edge portion about said aperture facing toward said end extremities; and attachment means cooperating with said first flange member and said second body member for moving said flange member toward said second body member and joining together said end extremities with said bore communicating with said opening said tubular member, sealing ring, circumferential recess, first flange member, second body arrangement and attachment means all being so constructed and arranged that, said beveled edge portion contacts and urges only a portion of said resilient sealing ring beyond said sealing ring seat toward and into sealing contact with said second body arrangement to provide a fluid-tight seal between said end extremities and said flange member.
Claim 2
Dependent Claim
194 words
A semiflexible fluid-tight tube coupling device, comprising: a first tubular member having an elongated axial bore and a uniform outer cylindrical surface except for a first circumferential recess sealing ring seat substantially immediately adjacent an end extremity thereof; a second body arrangement including an opening in an end extremity thereof; a first resilient sealing ring seated in said circumferential recess; a first flange member having an aperture therethrough slidably disposed about said outer cylindrical surface, said flange member including a beveled edge portion about said aperture facing toward said end extremities; and attachment means cooperating with said first flange member and said second body member for moving said flange member toward said second body member and joining together said end extremities with said bore communicating with said opening said tubular member, sealing ring, circumferential recess, first flange member, second body arrangement and attachment means all being so constructed and arranged that, said beveled edge portion contacts and urges only a portion of said resilient sealing ring beyond said sealing ring seat toward and into sealing contact with said second body arrangement to provide a fluid-tight seal between said end extremities and said flange member.
Claim 3
Dependent Claim
59 words
The tube coupling device according to claim 1, wherein said attachment means includes a pair of first attachment arrangements disposed in said first flange member on opposite sides of said bore, and also includes a pair of second attachment arrangements disposed in said second body arrangement on opposite sides of said opening and registering with said first attachment arrangement.
Claim 4
Dependent Claim
34 words
The tube coupling device according to claim 2, wherein said second body arrangement is a block and said end extremity thereof is planar, and wherein said opening communicates with a bore in said block.
Claim 5
Dependent Claim
48 words
The tube coupLing device according to claim 3, wherein said pair of second attachment arrangements are threaded studs extending orthogonally from said planar end extremity, and wherein said first attachment arrangements are holes and associated threaded nuts, said studs extending through said holes and threadably engaging said nuts.
Claim 6
Dependent Claim
95 words
The tube coupling device according to claim 2, wherein said second body arrangement includes a second tubular member having an elongated bore communicating with said opening and having a uniform outer cylindrical surface except for a second circumferential recess sealing ring seat immediately adjacent said end extremity thereof, and also includes a resilient sealing ring seated in said second circumferential recess, and further includes a second flange member having a second aperture therethrough slidably disposed about said second cylindrical surface and having a beveled edge portion about said second aperture facing toward said end extremities.
Claim 7
Dependent Claim
42 words
The tube coupling device according to claim 5, wherein said pairs of first and second attachment arrangements are holes and associated threaded nuts, and wherein said attachment means also includes a threaded stud extending through said holes and threadably engaging said nuts.
Claim 8
Dependent Claim
40 words
The tube coupling device according to claim 1, wherein the circumferential edge of said circumferential groove adjacent said end extremity is spaced from said end extremity by a distance not greater than the cross sectional radius of said sealing ring.
Claim 9
Dependent Claim
31 words
The tube coupling device according to claim 1, wherein said circumferential recess is semi-circular in cross section and has a cross sectional radius not greater than that of said sealing ring.
Claim 10
Dependent Claim
23 words
The tube coupling device according to claim 5, wherein said first and second sealing rings are joined by an integral web portion therebetween.
Claim 11
Dependent Claim
31 words
The tube coupling device according to claim 1, wherein said beveled edge portion defines a truncated conical surface making approximately a 45* angle with respect to the axis of the cone.
