  • Patent number: 10525578
    Abstract: A power tool includes a tool handle and a tool head. The tool handle includes a housing having a grip portion and defining a longitudinal axis, a motor disposed within the housing and including a drive shaft having an axis of rotation substantially parallel to the longitudinal axis, a trigger positioned adjacent the grip portion for selectively activating the motor, and a handle interface. The tool head is selectively coupleable to the tool handle and includes a head interface for coupling with the handle interface of the tool handle, a transmission driven by the drive shaft of the motor when the tool head is coupled to the tool handle, and an output member coupled to the transmission. The output member defines an axis generally perpendicular to the axis of rotation of the drive shaft.

  • Patent number: 9931743
    Abstract: A power tool having a removable head, a motor, a trigger, and a trigger stop movable between first and second positions. In the second position the trigger is unlocked to permit activation of the motor. A linkage is coupled to the trigger stop and is positioned at a first radial distance from the first central axis. A plurality of actuators extend from the head and are positioned at a second radial distance substantially equal to the first radial distance. When the head is coupled to the handle in a first rotational orientation, one of the plurality of actuators engages the linkage to move the trigger stop to the second position, and when the head is coupled to the handle in a second rotational orientation different from the first rotational orientation, another one of the plurality of actuators engages the linkage to move the trigger stop to the second position.

  • Patent number: 9085077
    Abstract: A power tool head is removably connectable to a power tool handle. The power tool head has an output for performing an operation on a work piece, and a housing having an inner surface defining a main cavity for receiving an interface of the power tool handle. The housing has an outer surface generally opposite the inner surface. The power tool head also has a first opening for selectively receiving a drive shaft for transferring rotation of the drive shaft to the output, the opening defining a central axis. The power tool head also has a pin extending substantially parallel to the central axis for depressing a trigger lock button, and a second opening extending from the inner surface to the outer surface in a direction generally radial with respect to the central axis for receiving a release member.

  • Publication number: 20140261367
    Abstract: A tile saw for cutting a workpiece includes a frame having a guide that extends from a first end to a second end. A first engagement member and second engagement member are coupled to the frame and disposed adjacent the first end, and a third engagement member is disposed adjacent the third end. A saw is coupled to the frame and is operable to rotate a cutting blade about an axis and a table is operable to support the workpiece. A pan is positioned to support the frame and contain a quantity of coolant. A fourth engagement member is coupled to the third engagement member and a first latch is selectively coupled to the first engagement member. A second latch is selectively coupled to the second engagement member. The first and second latch and the fourth engagement member cooperate to restrict movement of the frame with respect to the pan.
