The present disclosure relates to a powered screwdriver. The powered screwdriver includes a housing, a motor housed in the housing and a tool holder driven by the motor. The tool holder selectively holds both a screwdriver bit and a hex key. The hex key includes a bend such that legs of the hex key are transverse to one another.

Screwdriver and tool holder

A power tool having one or more sound damping members which reduce sound and/or vibration from one or more parts of a power tool. The sound damping member can reduce sound and/or vibration from static or dynamic parts of a power tool. The sound damping member can reduce noise and/or vibration from one or more rotating or moving parts of a power tool and its housing or internal structure. Methods, means, controls, systems and practices for reducing or eliminating undesired sound from a power tool are disclosed.

Power tool sound damping

A power tool includes a housing, a motor disposed in the housing, an output spindle configured to be driven by the motor, an input switch, and a controller configured to control power being delivered to the motor. The controller is operable in one of: (a) a normal mode where the controller causes continuous electric power to be delivered to the motor during actuation of the input switch in a first range of positions; and (b) a feathering mode where the controller causes discontinuous electric power to be delivered to the motor during actuation of the input switch in a second range of positions that is different from the first range of positions motor to simulate feathering the input switch.

Power tool with automatic feathering mode

A modification system for the modification of elongated pieces of stock may include a powered tool for modifying, or altering the piece of elongated stock, and a support device for supporting a position of the elongated stock relative to the powered tool. An arrangement of the components of the powered tool may provide for ergonomic balance of the powered tool. The support device may include a clamping device that clamps, or holds the elongated stock, and an adjustment device that adjusts a position of the clamping device based on a size of the elongated stock. The support device may include a latching device that maintains the position of the clamping device relative to the stock. A reaction arm may inhibit rotation of the tool relative to the stock during operation. A biasing device may provide for application of an axial biasing force on the stock, to initiate operation.

Pipe threading or cutting device

A powered tool follower assembly can include a solenoid plunger that is movable longitudinally in a direction aligned with a drive axis in response to energization of the solenoid and a biasing mechanism with a spring axis extending transversely to the drive axis. A lever arm can extend between the plunger and the biasing member and couple the plunger to the biasing mechanism. A pinch roller can be disposed between the lever arm and the driver. Energization of the solenoid can move the plunger longitudinally, causing relative movement between the lever arm and the drive wheel that forces the pinch roller into engagement with the driver and transfers a biasing force from the compression spring through the lever arm and pinch roller to the driver to pinch the driver between the pinch roller and the flywheel and drive the driver along the driver axis.

Powered hand-held fastening tool

A powered hand-held fastening tool includes a housing defining a handle, a frame, a motor-driven flywheel journaled to the frame, and an elongated driver that is selectively coupled to the flywheel to drive a fastener into a workpiece. The flywheel and driver have complementary sloped surfaces that mesh with each other to transmit energy from the flywheel to the driver to accelerate the driver along the driver axis. A follower assembly for selectively coupling the driver to the flywheel includes a solenoid actuator.

A cantilevered flywheel for a motor having an inner rotor. A power tool having an electric motor which drives a cantilevered flywheel. A fastening device having a driver blade and/or driver profile which has a driving action energized by a transfer of energy from contact with a cantilevered flywheel. Methods of using a cantilevered flywheel in power tools and appliances.

Power tool drive mechanism

A lighting device is provided including a first elongate light body supporting a first light source, a second elongate light body supporting a second light source, and first and second handles coupled to first ends of the first and second elongate light bodies. A rotary structure is disposed between second ends of the first and second elongate light bodies to support rotary movement of the first elongate light body with respect to the second elongate light body. A battery receptacle is disposed on the first elongate light body, a detachable light mount is disposed on the second elongate light body, and the detachable light mount is electrically connected to the battery receptacle. A detachable light is removably mounted on the detachable light mount.

Sound damping for power tools

A powered hand-held fastening tool includes a housing defining a handle, a frame, a motor-driven flywheel journaled to the frame, and an elongated driver that is selectively coupled to the flywheel to drive a fastener into a workpiece. A follower assembly for selectively coupling the driver to the flywheel includes a solenoid actuator, a biasing mechanism, a lever arm connected between the solenoid actuator and the biasing mechanism, and an intermediate member having journaled thereto a pivot roller and a pinch roller. Upon energization of the solenoid the lever arm is moved in a direction parallel to the drive axis, thereby applying a force on the pivot roller perpendicular to the drive axis, causing the pinch roller to press the driver against the flywheel and initiate the drive stroke. The intermediate member pivots about the pivot roller to release the pressure on driver upon completion of the drive stroke.

A driving tool with a housing, a motor received in the housing, a control unit and a trigger. The housing defines a handle. The control unit is configured to operate the motor and has a microswitch, an actuator arm and a spring. The actuator arm is biased by the spring toward the microswitch. The spring is configured to move the actuator arm against the microswitch to cause the microswitch to operate in an actuated switch state. The trigger is coupled to the handle and is movable between a first trigger position and a second trigger position. The trigger has a switch arm that cooperates with the actuator arm to form a lost-motion coupling that permits a predetermined amount of movement of the trigger from the first trigger position to the second trigger position before coupling the switch arm to the actuator arm. The actuator member does not contact the microswitch when the trigger is in the second trigger position so that the microswitch operates in a nominal switch state.
