Abstract

An adjustable telescoping union for repairing or connecting two ends of PVC pipe which cannot be manipulated lengthwise is provided in a two piece telescoping coupler. An internally lipped tubular housing having a retained sleeve sized to standard PVC pipe can be adjusted laterally to join two ends of the pipe and has gluing means for a permanent and leak-proof rejoining of the two separated pipe ends.

Claims

1. An adjustable union coupler for repairing and connecting PVC pipe ends comprising:

an elongated substantially tubular housing having longitudinal passageway therethrough for a tubular interior telescoping sleeve movably fitted therein;

said tubular housing internally lipped at one end thereof and fixable internally at the opposite end with a slip-reducing bushing;

said tubular telescoping sleeve affixed on the outer surface at one end with a restricting lip ring;

said restricting lip ring having a gluing groove circumvolved outwardly edgewise on the surface thereof and two longitudinal glue inlet groves on opposite sides in said outer surface of said lip ring commencing at said circumvolved gluing groove as inward lateral extensions thereof;

said tubular telescoping sleeve and said slip-reducing bushing both affixed with a pipe stop lip at adjacent interior positions;

said tubular housing apertured at said lipped end thereof for glue application therethrough onto said interior telescoping sleeve for glue attachment of said housing lip to said restricting lip ring and extrusion through said glue inlet grooves to said circumvolved gluing groove for permanent attachment of said interior lip ring to the internal surface of said housing;

said adjustable union coupler, the assemblage thereof, attachable at said slip-reducing bushing end to one end of a PVC pipe by adhesive means, and at said tubular telescoping sleeve end to one end of a second PVC pipe by longitudinal telescoping of said telescoping sleeve from said tubular housing and attachment thereof to said second end of PVC pipe with an external coupler by adhesive means.

2. The adjustable union coupler of claim 1 wherein said tubular housing internally lipped is structured with said internal lip being a plastic ring glued into said housing.

3. The adjustable union coupler of claim 1 wherein said tubular housing internally lipped is manufactured with said internal lip being a part thereof.

4. The adjustable union coupler of claim 1 wherein said slip-reducing bushing is structured with said bushing being a plastic ring glued into said housing after assemblage and installation of interior telescoping sleeve.

5. The adjustable union coupler of claim 1 wherein said slip-reducing bushing is manufactured into said housing and said lip is a plastic ring glued into said housing after assemblage and installation of interior telescoping sleeve.

6. The adjustable union coupler of claim 1 wherein said tubular housing aperatured at said lipped end thereof having said aperture being a hole through said housing structure and having a glue funneling entrance bevel in the outward surface of said housing.
