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.
Claims1
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.
