Description: |
| Machine translation of claims: "Device for fixing the handle and the head of wrenches and the like, which is connected to it by a joint and equipped with a ratchet mechanism, in various angular positions, characterized by a U-shaped spring-loaded bracket, one leg of which is guided in the hollow joint pin and the other leg of which is guided in a bore of one joint part and each engages in one of the holes arranged on a circle around the joint axis on the second joint part."
This is the "hinge joint" portion of the handle and ratchet in German DE-402,483 and British GB-205,819. Those patents' claims focus on the ratchet structure.
This "hinge joint" structure appears in the handle of "ALL-IN-ONE" distributed in the U.S. by Emil Schwarz (Chicago). That tool has been linked to U.S. patent 1,629,205, German patent DE-425,020, etc.
1921 write-ups and ads for the ALL-IN_ONE Wrench (Chicago) which seems to have features corresponding to these patents raise additional questions. German ads for the ALL-IN-ONE supply names for a couple of manufacturers. |
