  • Clamping arrangement for receiving a saw blade
    Patent number: 7003888
    Abstract: A saw blade clamping arrangement for a power tool includes a clamp support, a biasing member and an actuation member. The clamp support is interconnected with the drive shaft for reciprocating motion with the drive shaft relative to a housing of the power tool. The clamp support is configured to selectively receive a saw blade of the power tool in various orientations. A release lever is carried by the housing and is manually rotated to move a control member between a first position in which the saw blade is coupled to the drive shaft and a second position in which the saw blade may be displaced from the drive shaft. In at least one of the orientations, the saw blade is positioned offset from the drive shaft and proximate one of the side walls of the tool housing to allow for flush cutting of a work piece.

  • Blade ejection mechanism for a saw blade clamping arrangement of a power tool
    Patent number: 6502317
    Abstract: A powe tool includes a saw blade ejection mechanism for a saw blade clamping arrangement of a power tool. The power tool includes a housing, a drive shaft mounted for reciprocating motion relative to the housing and a saw blade. The clamping arrangement is operative for releasably connecting the saw blade with the drive shaft. The saw blade ejection mechanism includes a mounting member and an elongated plunger. The mounting member is adapted for attachment to the drive shaft. The elongated plunger is connected to the mounting member for movement between a first position to a second position for ejecting the saw blade from the saw blade clamping arrangement.
