Ratchet wrench
View Patent ↗A ratchet wrench has a through cavity in which a reversing lever is disposed. The reversing lever has a pair of protruding lips formed thereon opposite from one another. A cooperating ledge is formed on the head in the cavity and on the pawl which is adjacent to the reversing lever. A spring-loaded pusher is disposed longitudinally in a blind bore in the reversing lever and the pusher engages a pocket in the pawl. A cover plate is disposed on a shelf recessed on the bottom of the wrench and spaced apart from the reversing lever.
1. A ratcheting tool, the ratcheting tool comprising:
a. a head and a handle extending radially outwardly from the head;
b. a gear rotatably disposed in the head, the gear defining a first plurality of teeth on an outer circumference thereof;
c. a pawl disposed in the head so that the pawl is slidable both parallel to and perpendicular to a longitudinal center axis of the handle between
a first position in which the head transmits torque through the pawl in a first rotational direction, and
a second position in which the head transmits torque through the pawl in an opposite rotational direction,
the pawl defining
a second plurality of teeth on a front face of the pawl for engaging the first plurality of teeth,
a pocket defined in a rearward face of the pawl,
a shelf formed in the lower surface of the pawl; and
d. a lever defining a lip protruding therefrom, the lever being disposed in the head in driving engagement with the pawl so that actuation of the lever drives the pawl between the first position and the second position, wherein the lip is received by the shelf of the pawl, so that the pawl prevents upward motion of the lever relative to the head of the tool.
