  • Patent number: 11780152
    Abstract: An expansion tool includes a housing and an expansion head having a casing and jaws. The jaws are movable between a closed position and an expanded position relative to a longitudinal axis. 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.

  • Publication number: 20230256498
    Abstract: An expansion tool includes a housing, a motor supported by the housing and including a motor, a mandrel, and a drive mechanism configured to convert a rotational input from a motor shaft into translational movement of the mandrel. The expansion tool includes a first operating mode and a second operating mode. When the expansion tool is operated in the first operating mode, the drive mechanism is configured to reciprocate the mandrel between a retracted position and a first extended position. When the expansion tool is operated in the second operating mode, the drive mechanism is configured to reciprocate the mandrel between the retracted position and a second extended position different than the first extended position.

  • Publication number: 20230226628
    Abstract: 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.
