Abstract

In a ratchet tool having a toothed driving, a complementary coaxial, generally cylindrical rotatable toothed core within the ring, and a core-carried pivotal toothed double-ended pawl secured within the core and selectively positionable to intercouple the driving ring with the core for positively driving a core-carried tool element in each of two opposite torque-transmitting modes, improved means for pivotally shifting the pawl to a selectable mode of torque-transmitting core rotation, the improvement comprising finger actuable pawl-shifting means responsive to finger pressure applied along a vector which includes a force component directed axially into the core to effect, through intercoupling linkage, pivotal radial shifting of the pawl, alternately, between first and second driving-ring-engaging operational positions, and in which the pawl shifting means is conveniently manipulable with the same hand used to hold and to operate the tool. An additional important feature of the invention is that there is provided means whereby the tool user may palpably or visually readily perceive in which rotational mode the tool is set.
