Note(s)

  1. Attention is drawn to the notes preceding class F01, especially as regards the definitions of "rotary-piston machine", "oscillating-piston machine", "rotary piston", "co-operating members", and "internal-axis".
  2. The subject-matter of this sub-class comprises:
    1. rotary-piston or oscillating-piston engines for elastic fluids, e.g. steam,
    2. rotary-piston or oscillating-piston engines for liquids and elastic fluids,
    3. rotary-piston or oscillating-piston machines for elastic fluids,
    4. rotary-piston or oscillating-piston machines for liquids and elastic fluids.
  3. In this sub-class, the term "rotary-piston machine" embraces the German terms "Drehkolbenmaschinen", "Kreiskolbenmaschinen", and "Umlaufkolbenmaschinen".
