Abstract
A fluid-powered tool assembly having first and second tool members, a body, and first and second rotatable shafts. The first shaft is attached to the first tool member for rotation therewith about a first axis, and the second shaft is attached to the second tool member for rotation therewith about a second axis. A linear-to-rotary force transmitting member is mounted for reciprocal longitudinal movement in response to selective application of pressurized fluid thereto. The force transmitting member engages the first and second shafts to translate longitudinal movement of the force transmitting member in a first longitudinal direction into simultaneous rotational movement of the first shaft about the first axis in a first rotational direction and into rotational movement of the second shaft about the second axis in a second rotational direction, and to translate longitudinal movement of the force transmitting member in a second longitudinal direction opposite the first into opposite simultaneous rotational movements of the first and second shafts.
