Abstract
Abstract A molded plastic fitting particularly useful for joining together two tubular members. The fitting is a generally cylindrical molded plastic body having first and second ends, the first end being recessed axially to fit the outside of one tubular member, and the second end being radially inwardly offset from the first end by a circumferential step and dimensioned to fit inside the end of the other tubular member with the step abutting that end of the tubular member. Both ends of the molded body are bonded to the tubular members. A fastener passes through a transverse wall inside the molded body to clamp the molded body against the first tubular member. Both ends of the tubular member are constructed to give resiliently for proper fitting with the respective tubular members.

Claim 1
Independent Claim
212 words
A fitting for joining together two tubular members at an angle to each other, said fitting comprising a molded plastic body of generally cylindrical configuration having a first end and a second end, said first end being larger than said second end and offset radially therefrom by a step, said first end being substantially equal in diameter to that of one of said two tubular members and having a concave face recessed axially thereof, said concave face having a radius substantially slightly smaller than that of said one of said two tubular members to provide resilient wings which resiliently fit the outside of said one of said two tubular members, said second end being tubular, having a slightly greater diameter than the inside diameter of the other of said two tubular members and having at least two longitudinal slots therein to provide resilient sections which resiliently fit telescopically within the inside of said other of said two tubular members and said body having a transverse wall therein through which a fastener may be secured to said one of said two tubular members, and said transverse wall having annularly distributed ribs extending into said first end, into which said face is recessed, to provide a more extended weldable surface for said concave face.
Claim 2
Dependent Claim
212 words
A fitting for joining together two tubular members at an angle to each other, said fitting comprising a molded plastic body of generally cylindrical configuration having a first end and a second end, said first end being larger than said second end and offset radially therefrom by a step, said first end being substantially equal in diameter to that of one of said two tubular members and having a concave face recessed axially thereof, said concave face having a radius substantially slightly smaller than that of said one of said two tubular members to provide resilient wings which resiliently fit the outside of said one of said two tubular members, said second end being tubular, having a slightly greater diameter than the inside diameter of the other of said two tubular members and having at least two longitudinal slots therein to provide resilient sections which resiliently fit telescopically within the inside of said other of said two tubular members and said body having a transverse wall therein through which a fastener may be secured to said one of said two tubular members, and said transverse wall having annularly distributed ribs extending into said first end, into which said face is recessed, to provide a more extended weldable surface for said concave face.
Claim 3
Dependent Claim
217 words
A fitting for joining together two tubular members at an angle to each other, said fitting comprising a molded plastic body of generally cylindrical configuration having a first end and a second end, said first end being larger than said second end and offset radially therefrom by a step, said first end being substantially equal in diameter to that of one of said two tubular members and having a concave face recessed axially thereof, said concave face having a radius substantially slightly smaller than that of said one of said two tubular members to provide resilient wings which resiliently fit the outside of said one of said two tubular members, said second end being tubular, having a slightly greater diameter than the inside diameter of the other of said two tubular members and having at least two longitudinal slots therein to provide resilient sections which resiliently fit telescopically within the inside of said other of said two tubular members and said body having a transverse wall therein through which a fastener may be secured to said one of said two tubular members, said first end having at least two concentric rings into which said face is recessed and said plastic body being secured to said two tubular members at said first and second ends with solvent cement.
Claim 4
Dependent Claim
217 words
A fitting for joining together two tubular members at an angle to each other, said fitting comprising a molded plastic body of generally cylindrical configuration having a first end and a second end, said first end being larger than said second end and offset radially therefrom by a step, said first end being substantially equal in diameter to that of one of said two tubular members and having a concave face recessed axially thereof, said concave face having a radius substantially slightly smaller than that of said one of said two tubular members to provide resilient wings which resiliently fit the outside of said one of said two tubular members, said second end being tubular, having a slightly greater diameter than the inside diameter of the other of said two tubular members and having at least two longitudinal slots therein to provide resilient sections which resiliently fit telescopically within the inside of said other of said two tubular members and said body having a transverse wall therein through which a fastener may be secured to said one of said two tubular members, said first end having at least two concentric rings into which said face is recessed and said plastic body being secured to said two tubular members at said first and second ends with solvent cement.
