A transportable machine including an elongated frame having a top end and a bottom end, a handle disposed on the top end of the frame, a base disposed on the bottom end of the frame, where the base and the frame together define a space configured to receive and support a load, and a wheel disposed on the bottom end of the frame. A track is coupled to the frame, where the track includes a roller and an endless belt configured to rotate about the roller. A motor is coupled to the roller, where the motor is operable to drive the endless belt, and a power supply provides power to the motor.

Transportable machine including a track system

A portable pipe threader includes a housing, a carriage, and at least one pipe threading tool. A drive assembly of the is at least partially positioned within the housing and includes an electric motor operable to provide torque to the pipe. A lubrication system is removably coupled to the housing and includes a reservoir for holding a lubricant and a pump powered by the drive assembly. A stand of the portable pipe threader is adjustable between collapsed and deployed states. When collapsed, 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. When deployed, the longitudinal axis is maintained at a second oblique angle to funnel lubricant away from an end of the pipe on which a working operation is performed.

Lubrication system for portable pipe threader

A portable pipe threader includes a stand upon which a pipe is supported, a carriage supported by the stand upon which at least one pipe threading tool is supported, a spindle including a plurality of chuck jaws for clamping the pipe, the chuck jaws configured to move radially inward along a travel path toward an outer surface of the pipe, and a sensor system configured to determine a location of the chuck jaws along the travel path and relative to the outer surface of the pipe, the sensor system configured to output a signal corresponding to the location of each of the chuck jaws when engaged with the outer surface of the pipe. The portable pipe threader further includes an electronic controller in communication with the sensor system configured to determine an outer diameter of the pipe in response to the signal output from the sensor system.

Portable pipe threader

A portable pipe threader includes a stand upon which a pipe is supported, a carriage supported by the stand, and a plurality of pipe threading tools coupled to the carriage and selectively operable to perform work on the pipe. The portable pipe threader further includes a drive assembly mounted to the stand including a brushless direct current ('DC') motor operable to provide torque to one of the pipe or a selected one of the pipe threading tools to rotate the pipe and the selected one of the pipe threading tools relative to each other, and a battery pack supported by the stand in selective electrical communication with the motor to provide electrical power to the motor.

A feed mechanism for use with a drain cleaner includes a frame configured to be coupled to the drain cleaner. The frame including a cable passage defining a cable axis. The feed mechanism includes a plurality of rollers including a translatable roller. Each roller defines a roller axis. The translatable roller is moveable between an engaged position and a disengaged position. The feed mechanism includes a mode selection member coupled to the frame and moveable between a first position in which each roller axis is parallel to the cable axis and the plurality of rollers are configured to spin the cable about the cable axis, and a second position in which each roller axis is non-parallel to the cable axis and the plurality of rollers are configured to move the cable in a first direction along the cable axis.
