Description: |
| "L'objet de la présente demande de brevet est une clé ajustable pour boulons et écrous, destinée à trouver son emploi notamment en tous endroits où le transport d'un grand nombre de clés et le maniement des clés pour l'ajustement desquelles on est obligé de se servir des deux mains, constituent autant d'inconvénients."
Swiss patent corresponding to British patent GB-189217111 & German patent DE-65962 for a quick-adjust wrench - the movable jaw slides on an oval shank, and "binds" to hold adjustment. Known examples marked "CAM - Depose."
Manufacture attribution taken from Ron Geesin's entry for "C.A.M. Automatic Wrench Syndicate", vol. 2, pg. 42 of THE ADJUSTABLE SPANNER. Maynard was British, with his manufacturing plant in Belgium. A German ad lists 5 sizes of the "CAM." |
