ABSTRACT

An air ratchet hand tool has an elongated, generally cylindrical handle
portion with an axial air inlet passage therethrough, and having an outer
surface with two longitudinally extending channels formed therein, each
communicating with the air motor. A thermoplastic grip jacket covers the
handle portion and cooperates with the channels to form therebetween two
exhaust air passages which exit at the distal end of the handle. Longitudinal
ribs on the jacket project radially inwardly into engagement with longitudinal
recesses in the handle portion to inhibit relative rotational movement, while
a lug on the handle portion extends through an opening in the jacket to
inhibit relative axial movement. A flexible and resilient trigger cover covers
the valve trigger and the jacket opening through which it projects.
