Pipe Fusion Machine

Abstract

One fusion machine can butt or socket fuse polyolefin pipes and fittings in straight alignment or at inwardly or outwardly mitered universal angles from 0° to 45° for butt fusion and from 0° to 10° for socket fusion. The machine is manually driven, hydraulically monitored and operated in all configurations from one side of the machine.

What is claimed is: 
     
         1 . A machine for fusing polyolefin pipe, the machine comprising:
 a frame having a reference end and a drive end supporting spaced apart parallel guide rails therebetween in a horizontal plane;   a carriage mounted to slide longitudinally on said guide rails;   a drive reciprocating said carriage on said guide rails in response to directional force applied to said carriage; and   one pipe fusion jaw mounted on said frame and another pipe fusion jaw mounted on said carriage, each said jaw being rotatable about a respective pivot axis into mirrored angular orientation relative to a vertical plane perpendicular to said parallel guide rails;   whereby mirrored ends of pipes angularly aligned and horizontally extended by said jaws can be reciprocated by operation of said drive for fusion in a mitered relationship defined by said vertical plane.
