Abstract
An apparatus and method for joining pipes includes a plate for melting mating surfaces of the pipes to be joined. Additionally, the apparatus utilizes a vacuum in order to push the first and second pipes together in lieu of hand or mechanical pressure which may be inconsistent. Additionally, the vacuum allows the pipes to be joined to settle on each other in order to create a pressure about a periphery of the end of the pipe being joined to the other pipe. The consistent pressure creates a very strong joint between the first and second pipes.
Claims7
A heater plate of a pipe attaching machine for forming a liquid tight seal between a distal end of a first pipe and a second pipe, the heater plate comprising:
- a plate having opposed first and second sides sized and configured to mate with the distal end of the first pipe and the second pipe, the plate being operative to provide heat to the distal end of the first pipe and the second pipe for raising their temperatures to a softening temperature of the first and second pipes, the second side having a cup configured protrusion;
- and
- a handle attached to the plate, the handle being insulated from the plate so that the handle can be gripped by a person to manipulate the heater plate even when the plate is heated;
- wherein the cup configured protrusion defines an upper edge, the upper edge of the cup configured protrusion having a concave configuration.
A heater plate of a pipe attaching machine for forming a liquid tight seal between a distal end of a first pipe and a second pipe, the heater plate comprising:
- a plate having opposed first and second sides sized and configured to mate with the distal end of the first pipe and the second pipe, the plate being operative to provide heat to the distal end of the first pipe and the second pipe for raising their temperatures to a softening temperature of the first and second pipes, the second side having a cup configured protrusion;
- a handle attached to the plate, the handle being insulated from the plate so that the handle can be gripped by a person to manipulate the heater plate even when the plate is heated;
- wherein the plate has a through hole so that negative pressure created in a cavity of the first pipe is applied between the plate and the second pipe to hold the plate to the second pipe.
A heater plate of a pipe attaching machine for forming a liquid tight seal between a distal end of a first pipe and a second pipe, the heater plate comprising:
- a plate having opposed first and second sides sized and configured to mate with the distal end of the first pipe and the second pipe, the plate being operative to provide heat to the distal end of the first pipe and the second pipe for raising their temperatures to a softening temperature of the first and second pipes, the second side having a cup configured protrusion, an aperture disposed at a central area of the cup configured protrusion to allow negative pressure to flow therethrough with a vacuum;
- and
- a handle attached to the plate, the handle being insulated from the plate so that the handle can be gripped by a person to manipulate the heater plate even when the plate is heated.
