Abstract

Abstract 1. Pipe fusion apparatus for joining plastic pipe either coaxially in-line or at a selected angle to each other, comprising: (a) frame means having a longitudinal axis; (b) first pip clamp means with its axis parallel to said longitudinal axis, said clamp fastened to said frame near a first end thereof; (c) second pipe clamp means fixed near a second end of said frame for rigidly holding one pip so the its axis is at a selected angle to and in a plane passing through the axis of said first clamp; (d) third movable pipe clamp means slidably mounted on said frame between said first and second clamps thereof, said third clamp to retain another pipe at all times coaxial with said first clamp (e) means to longitudinally traverse said third clamprelative to said first clamp to provide said coaxial in-line pipe joints and relative to said second pip clamp to provide said angle type joints; and (f) means positionable co-axial to said third clamp to heat the opposed pipe surfaces.

Claims Analysis

Total Claims: 2
Claim 1
Independent Claim 170 words
Pipe fusion apparatus for joining plastic pipe either coaxially in-line or at a selected angle to each other, comprising: (a) frame means having a longitudinal axis; (b) first pip clamp means with its axis parallel to said longitudinal axis, said clamp fastened to said frame near a first end thereof; (c) second pipe clamp means fixed near a second end of said frame for rigidly holding one pip so the its axis is at a selected angle to and in a plane passing through the axis of said first clamp; (d) third movable pipe clamp means slidably mounted on said frame between said first and second clamps thereof, said third clamp to retain another pipe at all times coaxial with said first clamp (e) means to longitudinally traverse said third clamprelative to said first clamp to provide said coaxial in-line pipe joints and relative to said second pip clamp to provide said angle type joints; and (f) means positionable co-axial to said third clamp to heat the opposed pipe surfaces.
