Abstract: A powered ratchet tool including a housing and a drive mechanism for driving an output member. The drive mechanism includes a yoke through which the output member extends. The ratchet tool further comprises a first selective pawl, a second selective pawl, and a non-selective pawl in the yoke that are biased toward an outer toothed surface of the output member and blocking member. The outer toothed surface includes first and second selectively-toothed sections. When the first selectively-toothed section and second selectively-toothed sections are rotationally aligned with the with the first selective pawl and the second selective pawl, the first and second selective pawls are incapable of transferring torque to the output member. The blocking member moves between an operating position, wherein the non-selective pawl is engaged with the outer toothed surface, and a home position, wherein the blocking member inhibits the non-selective pawl from engaging with the outer toothed surface.

Abstract: A power tool includes a tool head having a working element and a powerhead configured to provide power to the working element. The powerhead includes a fluid tank configured to hold a combustible fuel and defines an initial internal volume having an internal pressure. A diaphragm is formed of a flexible material and forms at least a portion of the fluid tank. The diaphragm moves from an unexpanded state to an expanded state when a temperature of the combustible fuel increases above a threshold value. Movement of the diaphragm to the expanded state increases the internal volume of the fluid tank to allow the internal pressure of the fluid tank to remain approximately constant.

Abstract: A ratchet tool a handle housing and a ratchet assembly including a pawl and an output shaft. The pawl is moveable between a first position in which the pawl is operatively coupled to drive the output shaft in a first direction and a second position in which the pawl is operatively coupled to drive the output shaft in a second direction opposite the first direction. A switch in the handle housing has an external actuation surface for engagement with an operator's hand. The ratchet tool also has a rotatable gear having at least one tooth, the rotatable gear operatively coupled to the pawl such that rotation of the rotatable gear effectuates movement of the pawl between the first and second positions. A linkage is operatively coupled to the rotatable gear to effectuate rotation of the rotatable gear by actuation of the switch.
