Ratchet wrench

A ratchet wrench comprising a housing defining a chamber, a drive mechanism, a pawl arm, and a handle. The drive mechanism is adapted to mount a wrench member and is positioned proximate the distal end of the housing. The drive mechanism is adapted to mount a wrench member and is positioned proximat...

description	A ratchet wrench comprising a housing defining a chamber, a drive mechanism, a pawl arm, and a handle. The drive mechanism is adapted to mount a wrench member and is positioned proximate the distal end of the housing. The drive mechanism is adapted to mount a wrench member and is positioned proximate the distal end of the housing. The drive mechanism includes a ratchet first wheel having a first set of ratchet teeth oriented in a first direction and a second ratchet wheel having a second set of ratchet teeth oriented in a direction opposite that of the first set of ratchet teeth. A handle is connected to the housing for pivotal movement and is spaced apart from the drive mechanism. A pawl arm is mounted for reciprocating movement between the handle and the drive mechanisms such that one end is in operative association with the handle and the opposite end includes a first pawl for driving the first ratchet wheel in a first direction and a second pawl for driving the second ratchet wheel in the opposite direction. Upon movement of the handle, the pawl arm moves so that at least one of the pawls moves into contacting relation with the corresponding ratchet teeth to rotate the drive mechanism.
