Description:
Carriage wheel tire bolt wrench. A "rod" which holds the frame for the beveled gears also serves as the fulcrum for the lever handle which forces the socket into engagement with the nut of the tire bolt.

A known example is marked only with a patent date which appears to read "Patented July 10, 1902." It includes a secondary lever handle which appears to have been part of a clamping structure which may have included a means to hold the tire bolt from turning.
