Abstract: A pawl mechanism for an indexable tool and adapted to selectively transmit rotational motion of a yoke of the tool to a drive lug of the tool in one of first and second rotational directions. The pawl mechanism including a pawl carrier, first and second pawls pivotably coupled to the pawl carrier, and a selector switch rotatably coupled to the pawl carrier and adapted to selectively position the first and second pawls to transmit rotational motion of the yoke to the drive lug in one of the first and second rotational directions.

Abstract: An impact mechanism for an impact tool having a housing with a housing longitudinal axis, wherein the impact mechanism includes an impact mechanism longitudinal axis that is offset and substantially perpendicular to the housing longitudinal axis. The impact mechanism includes a gear carrier adapted to be driven by a motor of the impact tool to rotate about the impact mechanism longitudinal axis, a hammer slidably coupled to the gear carrier and rotatable about the impact mechanism longitudinal axis, the hammer includes a radial surface with a hammer lug extending therefrom, and an intermediate bit adapted to receive impact force from the hammer lug and transfer impact force to a tool bit.

Abstract: A display housing assembly has a base, a lens, and buttons. The base, lens, and buttons may be shaped to correspond with an external geometry of a tool housing, such as, for example, curved, arcuate or cylindrically shaped. The display housing assembly may also be assembled by molding the lens, molding the base over the lens, and molding the buttons over the base.

Abstract: A tool with two sequential gear trains and gear carrier assemblies adapted to be recessed into internal gears. The internal gear assembly also prevents rotation of the internal gear assembly relative to a housing of the tool. For example, the internal gear assembly can include a first gear train and second gear train sequentially coupled to the first gear train, wherein a first ring gear and first planet gears of the first gear train are substantially similar to a second ring gear and second planet gears of the second gear train.

Abstract: A motorized hand tool such as a cordless ratchet wrench is configured for reducing assembly and disassembly processes. The motorized hand tool includes a motor end plate that may be fastened to a drive member such as a ratchet head assembly without the use of fasteners or assembly tooling such as presses, fixtures or hammers. A flange on the motor end plate can pass through a keyway in a periphery of the ratchet head assembly and may be then be rotated out of the keyway and into a peripheral slot of the ratchet head assembly. A rib protruding inwardly from a clamshell housing portion of the tool closes the keyway to prevent the flange on the motor end plate from rotating back into the keyway.
