UNfound:

The Schade Typewriter was invented by engineer Rudolf Schade who referred to it as the "Schade System." The typewriter was produced ca.1896 at 119 Albrechtstraße in the Steglitz District of Berlin, Germany. The firm of Rudolf Schade Schreibmaschinen Fabrik (Rudolf Schade Typewriter Works) was the typewriter's manufacturer. To operate the Schade, the user would clamp it to a tabletop and insert a sheet of paper. The sheet would remain stationary as the  keyboard component of the machine would advance along the rails beneath.
