    Abstract: A rotary power tool comprises a drive mechanism including an electric motor and a transmission, a housing enclosing at least a portion of the drive mechanism, a spindle rotatable in response to receiving torque from the drive mechanism, a first ratchet coupled for co-rotation with the spindle, a second ratchet rotationally fixed to the housing, a sleeve bushing on an interior of the housing, and a bearing arranged between the spindle and the sleeve bushing and rotatably supporting the spindle. The bearing has an outer race. The spindle is movable relative to the housing in response to contact with a workpiece, causing the first and second ratchets to engage and the spindle to reciprocate while rotating. The outer race of the bearing moves along the sleeve bushing during reciprocation of the spindle when the first ratchet and second ratchet are engaged.

    Abstract: A hammer drill comprises a drive mechanism including a spindle, a first ratchet coupled for co-rotation with the spindle, a second ratchet rotationally fixed to the housing, and a hammer lockout mechanism adjustable between a first mode and a second mode. The hammer drill further comprises a clutch adjustable between a first mode and a second mode. The hammer drill further comprises a detent radially movable between a locking position and an unlocking position, and a collar movable between a first rotational position in which the hammer lockout mechanism is in the first mode and a second rotational position in which the hammer lockout mechanism is in the second mode. In the first mode the detent is positioned such that the spindle is moveable relative to the housing. In the second mode the detent is positioned such that the spindle is prevented from moving relative to the housing.

    Abstract: An impact tool includes a housing having a handle portion defining a first axis, a motor supported by the housing and defining a motor axis, and a rotary impact mechanism arranged on a second axis that is perpendicular to the first axis. The rotary impact mechanism is configured to convert a continuous rotational input from the motor to consecutive rotational impacts upon a workpiece. The rotary impact mechanism includes a chamber containing a hydraulic fluid, an anvil positioned at least partially within the chamber, and a hammer for imparting the consecutive rotational impacts upon the anvil. The hydraulic fluid is configured to attenuate a noise of the rotary impact mechanism that is created by the hammer impacting the anvil. The impact tool further includes a gear train that receives torque from the motor and includes a rotational input that transfers torque to the rotary impact mechanism.

    Abstract: A ratchet tool has a handle housing and a ratchet assembly including a pawl and an output shaft. The pawl is moveable between a first position in which the pawl is operatively coupled to drive the output shaft in a first direction and a second position in which the pawl is operatively coupled to drive the output shaft in a second direction opposite the first direction. A switch in the handle housing has an external actuation surface for engagement with an operator's hand. The ratchet tool also has a rotatable gear having at least one tooth, the rotatable gear operatively coupled to the pawl such that rotation of the rotatable gear effectuates movement of the pawl between the first and second positions. A linkage is operatively coupled to the rotatable gear to effectuate rotation of the rotatable gear by actuation of the switch.

    Abstract: A gas spring-powered fastener driver includes a cylinder, a moveable piston, a driver blade attached to the piston, the driver blade movable with the piston, a lifter including a rotary component operably coupled to the driver blade to move the driver blade from a driven position to a ready position, and a multi-stage planetary transmission. The transmission includes an output shaft operatively coupled to the lifter to provide torque thereto, a first bearing supporting a first portion of the output shaft for rotation, a second bearing supporting a second portion of the output shaft for rotation. The fastener driver also includes a housing having a cylinder support portion in which the cylinder is received and a transmission housing portion in which the first and second bearings are received to rotatably support the output shaft. The cylinder support portion and the transmission housing portion are integrally formed as a single piece.
