    Abstract: A power tool including a housing with left and right side walls, a rear wall extending between the left and right side walls, a left angled wall extending between the left side wall and the rear wall and a right angled wall extending between the right side wall and the rear wall. The power tool also includes a handle extending from the housing and defining a gap between the handle and the rear wall of the housing, a motor located within the housing, a fan driven by the motor, and a spindle driven by the motor to rotate about an axis. The left and right angled walls converge inwardly toward the axis in a front-to-rear direction along the axis. The housing includes air intake openings located on the left and right angled walls. Rotation of the fan draws an airflow into the housing through the air intake openings.

    Abstract: A cut-off saw including a housing, a support arm coupled to and extending from the housing in a first direction, a cutting wheel supported by the support arm, a rear handle extending from the housing in an opposite, second direction, a motor disposed in the housing, a battery pack configured to power the motor, and a battery receptacle defined by the housing in which the battery pack is receivable. The battery pack is positioned between the cutting wheel and the rear handle. The cut-off saw also includes a battery cover coupled to the housing. The battery cover is selectively moveable between a closed position, in which the battery pack is enclosed by the battery receptacle and the cover, and an open position, in which the battery pack is accessible.

    Abstract: An impact power tool includes a motor, an output shaft to which a tool bit is attachable for performing work on a workpiece, and an impact mechanism disposed between the motor and the output shaft for converting a continuous torque output from the motor to discrete pulses of torque upon the output shaft, the impact mechanism including a cylinder assembly, a cavity defined within the cylinder assembly containing a hydraulic fluid, and a collapsible member having a first end and a second end opposite the first end. The collapsible member is maintained in a shape coinciding with that of the cavity by fitment within the cavity, with the first and second ends being disconnected from each other. The collapsible member is collapsible to compensate for thermal expansion of the hydraulic fluid during operation of the impact mechanism.

    Abstract: A clutch mechanism is used in a rotary power tool having a motor. The clutch mechanism includes an input member to which torque from the motor is transferred and an output member co-rotatable with the input member. The output member defines a rotational axis. A cam surface is formed on one of the input member or the output member. First and second compression springs are carried by the other of the input member or the output member for co-rotation therewith. A follower has a circular cross-sectional shape and is biased against the cam surface by the first and second compression springs. In response to relative rotation between the input member and the output member, the cam surface displaces the follower along a line of action coaxial or parallel with each of the first and second compression springs. The line of action does not intersect the rotational axis.

    Abstract: A clutch mechanism, for use in a rotary power tool having a motor, comprises an input member to which torque from the motor is transferred and an output member co-rotatable with the input member, the output member defining a rotational axis. The clutch mechanism further comprises a cam surface formed on one of the input member or the output member and a compression spring carried by the other of the input member or the output member for co-rotation therewith. The clutch mechanism also comprises a follower having a circular cross-sectional shape biased against the cam surface by the compression spring. In response to relative rotation between the input member and the output member, the cam surface displaces the follower along a line of action coaxial or parallel with the spring. The line of action does not intersect the rotational axis.

    Abstract: A cart for carrying a cut-off saw having a saw blade. The cart includes a frame with upper and lower portions, a wheel arm pivotably coupled to the lower portion about a first axis, and a rear wheel assembly coaxial with the first axis and coupled to the frame and the wheel arm. The cart includes a front wheel coupled to an end of the wheel arm opposite the rear wheel assembly, an adjustment lever pivotably coupled to the upper portion about a second axis, and a link having a first end pivotably coupled to the adjustment lever and spaced from the second axis, and a second end pivotably coupled to the wheel arm between the first axis and the front wheel. Pivoting the adjustment lever about the second axis pivots the wheel arm about the first axis to adjust a vertical position of the front wheel relative to the upper portion.

    Abstract: A concrete vibrator includes a frame, a strap coupled to the frame, a main housing supported upon the frame, and an electric motor coupled to the main housing. The concrete vibrator further comprises a flexible shaft having a first end coupled to the motor and an opposite, second end. The concrete vibrator further comprises a vibrator head coupled to the second end of the shaft, the vibrator head configured to receive torque from the motor and the shaft to cause the vibrator head to vibrate. The concrete vibrator is operable in a backpack configuration in which the strap is used to carry the concrete vibrator with the frame in a vertical orientation, and in a briefcase configuration in which the frame is supportable in a horizontal orientation.
