A reciprocating saw includes a housing, a motor, and a drive mechanism. The motor includes an output gear rotatable about a motor axis. The drive mechanism includes a driven gear that engages the output gear and is rotated by the motor. The driven gear has a circumference and is vertically-oriented within the housing. The drive mechanism also includes an output shaft coupled to the driven gear and configured to reciprocate relative to the housing. The drive mechanism further includes a single counterweight fixed relative to the driven gear and rotating with the driven gear through a path and in a same direction. As the counterweight moves through a rearward half of the path, the counterweight generally moves in an upward direction, and as the counterweight moves through a forward half of the path, the counterweight generally moves in a downward direction.

Each jaw includes a first tapered portion defining a first length along the longitudinal axis, a first sizing portion extending parallel to the longitudinal axis from the first tapered portion and defining a second length along the longitudinal axis, a second tapered portion defining a third length along the longitudinal axis, and a second sizing portion extending parallel to the longitudinal axis from the second tapered portion and defining a fourth length along the longitudinal axis. The first sizing portions define a first diameter and the second sizing portions define a second diameter greater than the first diameter when the jaws are in the closed position. The third length is greater than the fourth length.

A drum unit is removably coupled to the base unit. The drum unit includes a rotatable drum, a cable stored within the drum and selectively extendable out of the drum and into a drain, and a second portion of the drive arrangement, where the second portion of the drive arrangement includes a driven shaft extending along an axis of rotation of the rotatable drum, where the driven shaft is rotatably fixed to the rotatable drum, and wherein the first portion of the drive arrangement is configured to drive the driven shaft and the rotatable drum when the drum unit is coupled to the base unit.

Drain cleaner

A drain cleaner includes a shroud with a closed end and an open end opposite the closed end and a drum assembly positioned within the shroud. The drum assembly is rotatable relative to the shroud. The drum assembly includes an inner drum and a drum cover extending entirely over an open forward end of the inner drum. The drain cleaner also includes a flexible cable stored within a cavity defined by the inner drum and the drum cover of the drum assembly. The flexible cable is supported by the inner drum. The drain cleaner further includes a handle assembly coupled to and extending rearwardly from the shroud. The handle assembly includes a motor, a grip, and an actuator to selectively energize the motor. The actuator is positioned in an area defined between the grip and the shroud.

An expansion tool includes a housing, a motor supported within the housing, a mandrel, and a drive mechanism configured to convert a rotational input from the motor into translational movement of the mandrel. The drive mechanism includes a cam and a drive shaft coupled to the cam. The expansion tool further includes a frame including a hub and a neck extending from the hub and having an opening. A working element is coupled to the neck and has a plurality of jaws movable from a closed position toward an expanded position in response to movement of the mandrel from a retracted position toward an extended position. The mandrel extends through the opening to engage the jaws, and the drive shaft is rotatably supported by the hub.

A reciprocating saw includes a housing, a motor, and a drive mechanism. The drive mechanism includes a driven gear that is rotated by the motor. The driven gear is vertically-oriented within the housing. The drive mechanism also includes a drive arm coupled to the driven gear to translate rotary motion of the driven gear into reciprocating motion, and an output shaft coupled to the drive arm to reciprocate relative to the housing along a spindle axis through a cutting stroke and a return stroke. The drive mechanism further includes a counterweight coupled to the driven gear and rotating with the driven gear through a path and in a same direction. As the counterweight moves through a rearward half of the path, the counterweight generally moves in an upward direction, and as the counterweight moves through a forward half of the path, the counterweight generally moves in a downward direction.

A drain cleaning device includes a drum, and a cable positioned within the drum. The cable is operable to be extended out of the drum and into a conduit. The drain cleaning device also includes a motor coupled to the drum to rotate the drum, a sensor operable to detect a characteristic of the cable, and a controller coupled to the sensor and the motor. The controller is configured to receive a signal from the sensor indicative of the characteristic of the cable and send an instruction to the motor to change an operating parameter of the motor based on the signal received from the sensor.
