ABSTRACT:
A manually actuated torque magnifying impact tool in which an annular inertia member surrounds and is directly supported rotationally on a common axis on a ratchet tool head. This construction confines impact stresses to the inertia member and tool head, instead of carrying these stresses through bearings and frame members as in former constructions, which required extra studiness in these members and thus undesirable extra weight in the tool.
