Abstract: An oscillating power tool has a housing including a handle portion defining a handle axis and a head portion defining an output axis that is perpendicular to the handle axis. The head portion includes a front face intersected by the handle axis. A drive mechanism includes an output shaft configured to oscillate about the output axis in a rotational manner in response receiving torque from a motor. A lighting assembly is configured to illuminate a workpiece in front of the head portion of the housing. The lighting assembly includes a lens arranged on the front face of the housing, a holder coupled to the lens, a plurality of printed circuit boards supported by the holder, and an LED arranged on each of the printed circuit boards. In response to being activated, the LEDs are configured to project a wide-angle beam of light through the lens.

Abstract: An oscillating power tool including a housing, a motor including a drive shaft rotatable about a motor axis, an output spindle configured to be driven by the motor and journaled for oscillating rotation about an oscillation axis, and a drive mechanism. The drive mechanism is configured to convert rotation of the drive shaft into oscillating rotation of the output spindle about the oscillation axis and includes an eccentric member and a forked member. Oscillating rotation of the forked member has an angular amplitude about the oscillation axis. The eccentric member is movable with respect to the forked member to change the angular amplitude of oscillating rotation of the forked member. An amplitude adjustment actuator is configured to move the eccentric member to change the angular amplitude of oscillating rotation of the forked member. The amplitude adjustment actuator defines a receptacle. At least a portion of the forked member is disposed in the receptacle.

Abstract: A powered fastener driver includes a driver blade movable from a top-dead-center position to a bottom-dead-center position for driving a fastener into a workpiece, a drive unit for providing torque to move the driver blade toward the top-dead-center position, and a rotary lifter engageable with the driver blade. The lifter having a body and a drive pin coupled to the body. A roller is positioned on the drive pin and engages with a tooth of the driver blade when moving the driver blade from the bottom-dead-center position toward the top-dead-center position. The roller includes a first engagement section that receives an end portion of the tooth and a second engagement section. An engagement member engages the second engagement section for aligning the first engagement section of the roller with the end portion of the tooth to facilitate meshing between the end portion of the tooth and the roller.

Abstract: A powered staple driver includes a magazine configured to receive staples and a nosepiece having a staple driving channel from which consecutive staples from the magazine are driven, the staple driving channel extending along a driving axis. The magazine obliquely extends from the nosepiece in both a first plane containing the driving axis and a second plane that is perpendicular to the driving axis.
