Abstract: 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.

Abstract: A power tool 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 and has an upper portion and a lower portion. The drive mechanism also includes a connecting rod coupled to the driven gear to translate rotary motion of the driven gear into reciprocating motion, and an output shaft coupled to the connecting rod to reciprocate relative to the housing through a cutting stroke and a return stroke. The drive mechanism further includes a counterweight coupled to the driven gear for rotation with the driven gear. The counterweight moves through the upper portion of the driven gear during the cutting stroke of the output shaft, and moves through the lower portion of the driven gear during a return stroke of the output shaft.

Abstract: A reciprocating saw including an outer housing positioned along a longitudinal axis of the reciprocating saw. The reciprocating saw also includes a motor casing covering a portion of a motor, and a gear casing positioned within the outer housing and coupled to the motor casing. A rib is formed on either one of the gear casing and the outer housing, and the rib extends substantially parallel to the longitudinal axis. In addition, a window is formed in either one of the outer housing and the motor casing. The rib forms an egress path between the gear casing and the outer housing in communication with the window.

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.

Abstract: A reciprocating saw includes a housing, a motor, and a drive mechanism. The motor is configured to operate in a forward mode corresponding to a first rotational direction, and in a reverse mode corresponding to a second rotational direction opposite the first rotational direction. The drive mechanism includes a driven gear, a connecting rod, an output shaft, and a counterweight. The driven gear is rotated by the motor and has an upper portion and a lower portion. The output shaft reciprocates through a cutting stroke and a return stroke. The counterweight is coupled to the driven gear and rotating with the driven gear. When the motor is operated in the forward mode, the counterweight moves through the upper portion of the driven gear during the cutting stroke of the output shaft, and moves through the lower portion of the driven gear during a return stroke of the output shaft.
