Description: |
The patent describes a hex-drive socket wrench set including a crank-type handle, universal joint, extension bars, hex to square drive adapter, and "T" handle with a sliding round bar handle. They use ball detents for stops and to secure connections. The patent claim is for the "T" handle.
The ratchet is mentioned as being the subject of a separate patent application -- it is covered by patent nos. 1,614,039 and 1,628,467.
Some of the components are pictured in a 1925 "Automobile Digest" advertisement for the Husky No. 120 Heavy Duty Set. |
