Description: |
| Angled jaw adjustable wrench; the movable jaw slides on a "flat oval" shank and is adjusted by a screw parallel to that shaft. German wrench designs included a similar form without adjusting screw where the adjustment was held only by friction.
Note the spelling variation (Riem vs. Riehm) in the descriptive article and the brief listing.
German Gebrauchsmuster Registrations are not included in online patent sources. They are known only from the German patent office's PATENTBLATT and from lists and notices in trade publications and the like. |
