The ratchet-wheel is; secured to the rear and the front face oE-th'e wheel isreces'sedms pivot screw, H. This pivot screwis threaded projects beyond the rearsid'e of the same and is eng g d by me I'- The reversible .pawl, K -'is f nlcrnmed upon the handle in position to. engage the ratchet, wheel, and is'provided with a wedge-shaped detent', L, which is engaged, to hold the pawl in the desired position, by a latch, M. This latchis seated in a. channel, N, in the handle. of the wrench, and comprises, essentially, a

bowed slide, 0, and a spring tongne,'P. The

bowed slide is provided with a longitudinal slot, 0, which is engaged .by a set-screw, Q,

taking into'the handle, whereby the latch is capable of longitudinal movement except when locked in position by the tightening of the set-screw. The latch is normallypressed' forward by the coiled actnating'spring, R,
