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, said ratcheting tool comprising:
a. a head and a handle attached to said head, said head having a top end and a bottom end;
b. a gear rotatably disposed in said head, said gear defining a first plurality of teeth on an outer circumference thereof;
c. a pawl disposed in said head so that said pawl is slidable both parallel to and perpendicular to a longitudinal center axis of said handle between
a first position in which said head transmits torque through said pawl in a first rotational direction, and
a second position in which said head transmits torque through said pawl in an opposite rotational direction,
said pawl defining
a second plurality of teeth on a front face of said pawl for engaging said first plurality of teeth,
a pocket defined in a rearward face of said pawl,
a shelf formed in said lower surface of said pawl; and
d. a lever defining a lip protruding therefrom, said lever being disposed in said head in driving engagement with said pawl so that actuation of said lever drives said pawl between said first position and said second position, wherein said lip is received by said pawl shelf, and said pawl moves both parallel to and perpendicular to said longitudinal center axis of said handle when ratcheting occurs.
2. The ratcheting tool of claim 1 , further comprising a spring-loaded pusher carried by said lever, wherein said pusher engages said pocket of said pawl.
3. The ratcheting tool of claim 2 , wherein said pusher is parallel to said longitudinal center axis of said handle.
4. The ratcheting tool of claim 1 , wherein said head further defines a through cavity, and said gear, said pawl and said lever are disposed in said through cavity.
5. The ratcheting tool of claim 4 , further comprising a cover plate disposed in said through cavity beneath said gear, said pawl and said lever.
6. The ratcheting tool of claim 1 , said lever further comprising an arm that is adjacent a top end of said head of said lever.
