ABSTRACT:
Ratchet wrench, having a motor drive and having a member which oscillates angularly, cooperating with a rotor, which intermittently drives a shaft angularly through a pre-determined number of degrees, the shaft being configurated to carry a socket to fit a nut to be turned. The wrench has a head which carries the oscillating member and a ratchet pawl. A manual adjustment is provided to adjust the pawl for driving the shaft in either direction as desired. The ratchet pawl is carried in the rotor member which is mounted in the head and which carries the shaft on which is mounted the socket for fitting on the nut to be turned. All of the parts are held within the head with appropriate friction being applied to the rotor by use of a wave washer.
