Description:

An 1894 write-up for the COLUMBUS adjustable wrench from v. STEIN & Co. (Remscheid) included its basis in D.R.G.M. 8481.

The Oct. 9, 1895 PATENTBLATT citation used in this entry was the 1895 "extension" for the registration. Original effective date Oct. 5, 1892, extended to Sept. 24, 1895.

German Gebrauchsmuster Registrations are not included in online patent sources. They are known only from the German patent office's PATENTBLATT (where they are listed by Patent classification rather than by registration number) and from lists and notices in trade publications and the like. Most tools produced with D.R.G.M. "protection" do not include the registration number on the tool.
