    摘要: The tool has a circular body, and an actuating lever pivotably coupled thereto. The lever, however, has two limbs, joined through a bight, and one of the limbs is fully nested in a recess formed therefor in the body. Consequently, one may grasp the tool about the body, whereat the one limb is nested, without turning the tool on, inadvertently. The other limb extends outwardly from the body, however, and by grasping the tool thereat, and depressing this other limb, the tool is turned on.

    摘要: A pneumatic tool has a one-piece metal tube forming an air motor cylinder and an associated air inlet plenum. Air passages are formed between an inner housing, molded in situ about the motor cylinder tube, and an outer housing separately molded. The inner and outer housings are both formed from a non-metal composite material which contributes to operator comfort by its light weight, thermal insulation, vibration damping, and noise suppressing properties. The tool may be assembled to provide forward exhaust, rearward exhaust, or combined forward and rearward exhaust.
