Description:

The key features are the matching "rack" type teeth and internal springs forming "one-way" ratchets, and the use of a standard hex shaft for handle, extension, etc. which allows the tool to reach into places difficult of access.

A December, 1921 ad shows the patent employed in a complete ratchet socket set.
