Improvement to the ratchet in 4,934,220. The patent number is reported on a WILLIAMS branded ratchet; Snap-On acquired WILLIAMS ca. 1994.
Abstract
A reversible ratchet wrench has a ratchet body with a cavity receiving the ratchet assembly. A pawl-engaging reversing lever is insertable through an opening in the ratchet body from the cavity and has a flange dimensioned to be trapped between the body and the pawl. A seal between the reversing lever and the ratchet body is provided by an O-ring seated in a groove in the outer surface of the reversing lever hub. A cover plate closes the cavity and cooperates with the pawl and the flange to retain the reversing lever in place.
