A reciprocating shaft assembly in a reciprocating saw moves in a reciprocal motion and drives a saw blade via a blade holder. At least one bore is formed in an end of the reciprocating shaft assembly opposite the blade holder. A pin fixed to the saw passes through the bore and acts as a bearing to support the reciprocating shaft assembly in its reciprocating motion.

Bearing structure for a reciprocating shaft in a reciprocating saw

A counterweight in a reciprocating saw counterbalances a reciprocating shaft assembly adapted to hold a saw blade. The counterweight is supported for reciprocating motion by slides which ride within slots formed in a housing adapted to hold the reciprocating mechanism.

Reciprocating counterweight structure for a reciprocating saw

A reciprocating power tool includes a motor operatively connected with a drive assembly for driving a reciprocating shaft, on which a working tool is supported. The reciprocating power tool includes a base so that the tool may stand upright when resting upon the base without the use of external supports. A counterweight positioned inside of the drive housing minimizes vibration. The motor is preferably positioned so that its rotational axis is angled with respect to a longitudinal axis of the reciprocating shaft. This configuration of the motor produces a compact configuration for a reciprocating power tool and helps the tool stand upright upon the base of the tool. A battery may be provided in a cordless embodiment and is advantageously positioned for balancing the tool.
