Description: |
| The reversible ratchet built into the "head" has pawls with partial "gear" teeth and a surrounding ring with corresponding internal teeth.
One form of resulting wrench was distributed in the U.S. by the Emil Schwarz Co. (Chicago) as the driver for a 5/8" hex drive "ALL-In-ONE" ratchet and socket set. These were manufactured in Germany and imported. The ESPACENET entry for the patent lists corresponding patents from several European countries -- DE-425,020 is the German patent.
The overall structure of "ALL-IN-ONE" includes features similar to British patent GB-205,819 and corresponding German patent DE-402,483 -- Hirsch & Mayer, Feuerbach. |
