Abstract: An oscillating power tool includes a housing, a motor, a tool holder driven oscillatingly, a flange threadedly coupled to a plunger, and a lever pivotable between a clamping position and a release position. The flange is configured to be movable in an axial direction. The flange is configured to clamp the output element onto the tool holder in the clamping position and configured to be displaced a first distance from the tool holder in the release position. The lever includes a cam surface including a substantially flat surface configured to engage the plunger in the release position. In the release position, a gap is disposed between the lever and the housing to allow the lever to be rotated past the release position. The lever is configured to displace the flange a second distance from the tool holder, larger than the first distance, when rotated past the release position.

Abstract: A transducer assembly for use in a power tool including a housing, a motor, an output shaft that drives a workpiece about a central axis, and a transmission. The transducer assembly includes a transducer positioned between the motor and the transmission. The transducer including an inner hub being rotationally affixed to the housing, an outer rim affixed to a rotatable component of the transmission, a plurality of webs extending radially outward from the inner hub to the outer rim, and a sensor affixed to each of the webs for detecting strain of each of the webs in response to a reaction torque applied to the transmission from the output shaft. A width of each of the webs gradually tapers from at least one of the outer rim or the inner hub toward a midpoint of each of the webs in a direction perpendicular to the central axis.

Abstract: A cut-off saw configured to remove material from a workpiece, the cut-off saw includes a motor, a blade, a drive assembly, a handle, and a coating. The blade is capable of removing material from the workpiece upon contact between the blade and the workpiece. The drive assembly is coupled to the motor and the blade and is configured to transmit torque from the motor to the blade. The handle is configured to be grasped by a user, and includes a surface and a first material having a first surface resistivity. The coating covers at least a portion of the handle. The coating is configured to distribute static electricity away from the surface. The coating is made of a second material having a second surface resistivity less than the first surface resistivity.

Abstract: A powered fastener driver including a housing, an inner cylinder within the housing, and a piston movable within the inner cylinder from a TDC position to a BDC position. The piston has a diameter of less than 1.7 inches. A stroke length of the piston is between the TDC position and the BDC position measuring greater than 3 inches. A driver blade is attached to the piston for movement therewith along a driving axis. A lifter is operable to move the piston and driver blade from the BDC position toward the TDC position. A drive unit is operably coupled to the lifter to provide torque thereto, causing the lifter to rotate. A source of pressurized gas is in fluid communication with the inner cylinder. A pressure of the pressurized gas acting on the piston at the TDC position is greater than 180 psi.

Abstract: A powered fastener driver includes a housing, a nosepiece coupled to the housing, a driver blade movable within the nosepiece between a ready position and a driven position, a canister magazine coupled to the nosepiece and including collated fasteners arranged in a coil, and a pusher mechanism coupled to the nosepiece for individually transferring collated fasteners from the canister magazine to a driver channel in the nosepiece, wherein the pusher mechanism includes: a linkage assembly having a support arm, a finger pivotably coupled to the support arm, a lever pivotably coupled to the support arm via and a fork pivotably coupled to the lever via a second fixed pivot, and a feeder arm engaged with the fork. The feeder arm pushes fasteners into the driver channel as the pusher mechanism is actuated by the impact of the driver blade during a retraction stroke of the driver blade.

Abstract: A gas spring-powered fastener driver includes a cylinder, a moveable piston positioned within the cylinder, a driver blade attached to the piston and movable therewith between a ready position and a driven position, a lifter to move the driver blade from the driven position to the ready position, and a transmission including an output shaft operatively coupled to the lifter to provide torque to the lifter. The fastener driver also includes an input to provide torque to the transmission and a clutch positioned downstream of the input and operably coupled to the output shaft to limit an amount of torque transferred to the output shaft and the lifter. In response to an application of a reaction torque to the output shaft above a predetermined threshold, torque from the input is diverted from the output shaft via the clutch.

Abstract: A power tool includes a housing, a motor positioned within the housing, and an impulse assembly coupled to the motor to receive torque therefrom. The impulse assembly including a cylinder at least partially forming a chamber containing a hydraulic fluid, an anvil positioned at least partially within the chamber, and a hammer positioned at least partially within the chamber and engageable with the anvil for transferring rotational impacts to the anvil. The hammer includes a surface facing the anvil, a first through hole formed in the surface and a second through hole formed in the surface. The impulse assembly further includes a biasing member biasing the hammer towards the anvil. The flow of the hydraulic fluid through the first through hole varies as the hammer translates away from the anvil.
