Abstract
A portable pipe threader includes a housing, a carriage supported by the housing, at least one pipe threading tool coupled to the carriage and selectively operable to perform work on a pipe, a drive assembly at least partially positioned within the housing including an electric motor operable to provide torque to the pipe, and a lubrication system removably coupled to the housing, the lubrication system including a reservoir for holding a lubricant and a pump supported upon the reservoir and configured to draw the lubricant from the reservoir, the pump being powered by the drive assembly.
Claims20
A portable pipe threader comprising:
- a housing;
- a carriage supported by the housing;
- at least one pipe threading tool coupled to the carriage and selectively operable to perform work on a pipe;
- a drive assembly at least partially positioned within the housing, the drive assembly including an electric motor operable to provide torque to the pipe;
- and
- a lubrication system removably coupled to the housing, the lubrication system including a reservoir for holding a lubricant and a pump supported upon the reservoir and configured to draw the lubricant from the reservoir, the pump being powered by the drive assembly.
A portable pipe threader comprising:
- a housing;
- a carriage supported by the housing;
- at least one pipe threading tool coupled to the carriage and selectively operable to perform work on a pipe;
- a drive assembly at least partially positioned within the housing, the drive assembly including an electric motor operable to provide torque to the pipe;
- and
- a lubrication system including a reservoir coupled to the housing, a valve positioned within an inlet of the reservoir, and a basin positioned beneath the carriage,
- wherein the basin includes an inclined bottom wall for directing lubricant toward the reservoir, and wherein the valve is actuated from an open position, in which lubricant may flow through the reservoir inlet and into the reservoir, and a closed position, in which lubricant is prevented from exiting the reservoir through the reservoir inlet, in response to removing the reservoir from the basin.
A portable pipe threader comprising:
- a housing;
- a carriage supported by the housing;
- at least one pipe threading tool coupled to the carriage and selectively operable to perform work on a pipe;
- a drive assembly at least partially positioned within the housing, the drive assembly including an electric motor operable to provide torque to the pipe;
- a lubrication system removably coupled to the housing, the lubrication system including a reservoir for holding a lubricant and a pump powered by the drive assembly;
- and
- a stand adjustable between a collapsed state and a deployed state,
- wherein, in the collapsed state, a longitudinal axis of the housing is maintained at a first oblique angle relative to a horizontal reference plane parallel with a work surface upon which the stand is supported to funnel lubricant toward the reservoir, and in the deployed state, the longitudinal axis of the housing is maintained at a second oblique angle relative to the horizontal reference plane parallel with the work surface upon which the stand is supported to funnel lubricant away from an end of the pipe on which a working operation is performed.
