  • Patent number: 9186735
    Abstract: A reciprocating saw having a clamping arrangement with a clamp support base, a first locking member and a release lever. The clamp support base defines a first blade slot that is configured to receive a saw blade therein. The first locking member is movable between a disengaged position, which does not inhibit withdrawal of the saw blade from the first blade slot, and an engaged position that inhibits withdrawal of the saw blade from the first blade slot. The release lever is pivotally coupled to the clamp support base and coordinates movement of the first locking member.

  • Patent number: 8826549
    Abstract: A reciprocating saw having a clamping arrangement with a clamp support base, first and second locking members and a release lever. The clamp support base defines first and second blade slots that are each configured to receive a saw blade therein. Each of the first and second locking members are movable between a disengaged position, which does not inhibit withdrawal of the saw blade from the a corresponding one of the first and second blade slots, and an engaged position that inhibits withdrawal of the saw blade from the corresponding one of the first and second blade slots. The release lever is pivotally coupled to the clamp support base and coordinates movement of the first and second locking members.

  • Publication number: 20130299207
    Abstract: An electric power tool is provided. The electric power tool includes a motor housing having inlet and outlet slots and an electric motor received within the motor housing. The electric motor is configured to drive a working spindle. The electric power tool includes a ventilation device disposed within the motor housing and configured to generate an airflow between the inlet and outlet slots. The electric power tool also includes an airflow gear case attached to the motor housing. The airflow gear case having an opening to receive the working spindle and bearings. An airflow sleeve covers the airflow gear case, wherein at least a portion of the airflow received from the motor housing is introduced along an airflow path defined by the airflow gear case and the airflow sleeve.

  • Patent number: 8555516
    Abstract: A saw blade clamping arrangement for a power can include a clamp support base that is operatively coupled for movement with a drive shaft and has a first and a second, saw blade slots. First and second locking members can be operatively associated with the clamp support base and be movable between a locked position that selectively locks the blade in one of the corresponding first and second slots, and an unlocked position that releases the blade. A release member can rotate to cause the first cam surface to urge the first locking member at least partially into the first slot and the second cam surface to concurrently urge the second locking member at least partially into the second slot. In another configuration, the release member can alternatively urge the first or second locking member into the respective slots.
