Abstract
Abstract Relates to a leaktight coupling having a dual capability of joining two lines together in either an easily demountable relationship or a relatively permanent relationship. Includes flanged tubular members, axially aligned with their flanges adjacent, and a sealing member disposed between said flanges. To connect two lines in a demountable relationship, one line is permanently secured to one tubular member, the other line being passed through the other tubular member, through the sealing member, and partially into the first tubular member, the sealing member holding the second line in place. To connect two lines in a permanent relationship, the lines are permanently secured to respective ones of the tubular members, and the ends of a sleeve carrying the sealing member extend respectively into the tubular members. In either use, a clamping device draws the flanged tubular members together.

Claim 1
Independent Claim
195 words
A coupling for connecting two tubular lines together, comprising: first and second tubular members, each of said tubular members having a flanged portion on one end thereof, said tubular members being axially aligned with the respective flanged portions adjacent, each of said tubular members having an inner diameter dimensioned to receive respective ones of the lines; an annular resilient sealing member operatively disposed between said adjacent aligned flanged portions; and means for drawing said flanged portions together; said first tubular member adapted to have one of the lines partially inserted thereinto from the unflanged end thereof and to have this line permanently secured thereto, said unflanged end of said first tubular member extending through and axially beyond at least a portion of said drawing means said second tubular member having the second line extending completely therethrough, through said sealing member, and partially into said first tubular member, wherein said sealing member tightly embraces and is supported by the second line, and holds this line in place, said drawing means being operative to draw said flanged portions together to compress said sealing member into high leaktight sealing engagement with said flanged portions and the second line.
Claim 2
Dependent Claim
195 words
A coupling for connecting two tubular lines together, comprising: first and second tubular members, each of said tubular members having a flanged portion on one end thereof, said tubular members being axially aligned with the respective flanged portions adjacent, each of said tubular members having an inner diameter dimensioned to receive respective ones of the lines; an annular resilient sealing member operatively disposed between said adjacent aligned flanged portions; and means for drawing said flanged portions together; said first tubular member adapted to have one of the lines partially inserted thereinto from the unflanged end thereof and to have this line permanently secured thereto, said unflanged end of said first tubular member extending through and axially beyond at least a portion of said drawing means said second tubular member having the second line extending completely therethrough, through said sealing member, and partially into said first tubular member, wherein said sealing member tightly embraces and is supported by the second line, and holds this line in place, said drawing means being operative to draw said flanged portions together to compress said sealing member into high leaktight sealing engagement with said flanged portions and the second line.
Claim 3
Dependent Claim
201 words
A coupling for connecting two tubular lines together, comprising: first and second tubular members, each of said tubular members having a flanged portion on one end thereof, said tubular members being axially aligned with the respective flanged portions adjacent, each of said tubular members having an inner diameter dimensioned to receive respective ones of the lines; an annular resilient sealiNg member operatively disposed between adjacent aligned flanged portions; means for drawing said flanged portions together; said first tubular member adapted to have one of the lines partially inserted thereinto from the unflanged end thereof and to have this line permanently secured thereto, said second tubular member adapted to have the second line partially inserted thereinto from the unflanged end thereof and to have this line permanently secured thereto; and a sleeve member having a constant outer diameter positioned in and dimensioned to engage the interior of said tubular members in close, free, slidable relationship; wherein said sealing member tightly embraces and is supported by said sleeve member and holds said sleeve in place, said drawing means being operative to draw said flanged portions together to compress said sealing member into high leaktight sealing engagement with said flanged portions and said sleeve.
Claim 4
Dependent Claim
201 words
A coupling for connecting two tubular lines together, comprising: first and second tubular members, each of said tubular members having a flanged portion on one end thereof, said tubular members being axially aligned with the respective flanged portions adjacent, each of said tubular members having an inner diameter dimensioned to receive respective ones of the lines; an annular resilient sealiNg member operatively disposed between adjacent aligned flanged portions; means for drawing said flanged portions together; said first tubular member adapted to have one of the lines partially inserted thereinto from the unflanged end thereof and to have this line permanently secured thereto, said second tubular member adapted to have the second line partially inserted thereinto from the unflanged end thereof and to have this line permanently secured thereto; and a sleeve member having a constant outer diameter positioned in and dimensioned to engage the interior of said tubular members in close, free, slidable relationship; wherein said sealing member tightly embraces and is supported by said sleeve member and holds said sleeve in place, said drawing means being operative to draw said flanged portions together to compress said sealing member into high leaktight sealing engagement with said flanged portions and said sleeve.
