Description:
The offset in the handle places the center of the "T" in line with the socket. A spring clip on the socket allows allows interchangeability, and the sockets can face toward or away from the handle. SUCCESS Ratchet Cylinder Tooth Wrench ads starting August 1902 show this form of wrench head. The ratchet portion is noted, but is not described in detail; it probably is a refinement of the J.P. Johnson patent no. 601,146.
