250 - Johann SCHMITT
SCHMITT, resident of Koblenz, had developed in 1874 a novel knitting machine. He patented it in Germany and France , for example, but not in Luxembourg.
On 23 September 1879, however, he applied in Luxembourg for a brevet de perfectionnement of his earlier invention under title of:
Innovations et perfectionnements à la machine à tricoter dite “Schmittsche Strickmaschine”
The application proceeded, without examination, to grant under the 1880 Patent Law on 23 July 1880.
