1. An apparatus for fusing molten portions of pipe together comprising:
- a support frame;
fixed clamp means on said support frame to retain a molten portion of said first section of pipe in a fixed axial position;
movable clamp means adapted to retain a molten portion of a second section of pipe axially spaced from said molten portion of said first section of pipe, said movable clamp means movably supported upon guide rods, said guide rods fixed to said support frame on each side of said pipe the axis of which lies in an imaginery plane which intersects the central axis of said molten portions of said first and second pipe sections;
means to move said clamp means bringing said molten pipe portions into contact for fusion; and
means in communication with said movable clamp means to indicate the force applied to said molten pipe portions when drawn together into contact for fusion.

Abstract
A portable wheeled apparatus for fusing plastic pipe having a support frame with stationary clamps attached thereto and movable clamps in axial alignment therewith. A first pipe section is secured within the stationary clamps and a second pipe section is secured within the movable clamps and are brought into contact for facing, heating and fusing by a manually operated handle. The apparatus is provided with retention devices to maintain a given axial force applied to the pipe sections during fusing. An indicator device is in communication with the movable clamps to display the force applied to the pipes.
