    Abstract: A power tool comprises an adjustable auxiliary handle assembly that facilities safe use of the tool by the operator when handling heavy duty handheld machinery. The adjustable auxiliary handle assembly comprises a strap, a handle base, an over-center linkage assembly, a locking lever, a locking lever and an adjustable knob. The strap is easily released and able to rotate and be locked in a different position convenient and comfortable to the operator. The auxiliary handle assembly is adjustable and can be operated with one hand (e.g., one-handed operation). The over-center linkage assembly holds the auxiliary handle position in place while allowing the power tool to be used in high-torque/high load applications.

    Abstract: Illustrative embodiments of impact tools with impact mechanisms rigidly coupled to electric motors are disclosed. In at least one illustrative embodiment, an impact tool may comprise an impact mechanism, an electric motor, and a control circuit. The impact mechanism may comprise a hammer and an anvil, the hammer being configured to rotate about a first axis and to periodically impact the anvil to drive rotation of the anvil about the first axis. The electric motor may comprise a rotor that is rigidly coupled to the impact mechanism, the electric motor being configured to drive rotation of the hammer about the first axis. The control circuit may be configured to supply a current to the electric motor and to prevent the current from exceeding a threshold in response to the hammer impacting the anvil.

    Abstract: A pneumatic motor includes a stator having a stator inner wall including a dwell region and a rotor eccentrically disposed within the stator. The rotor is configured to rotate about the axis of rotation and includes a plurality of vanes disposed around the rotor. Each vane of the plurality of vanes is configured to slide within a respective slot formed in the outer surface of the rotor between a fully retracted position and a fully extended position as the rotor rotates about the axis of rotation to maintain contact with the stator inner wall. The stator inner wall has a radius relative to the axis of rotation that is substantially constant within the dwell region so that vanes of the plurality of vanes are in the fully extended position within the dwell region.
