F 01 B

 MACHINES OR ENGINES, IN GENERAL OR OF POSITIVE-DISPLACEMENT TYPE, e.g. STEAM ENGINES (of rotary-piston or oscillating-piston type F 01 C; of non-positive-displacement type F 01 D; internal-combustion aspects of reciprocating-piston engines F 02 B 57/00, F 02 B 59/00; crankshafts, crossheads, connecting-rods F 16 C; flywheels F 16 F; gearings for interconverting rotary motion and reciprocating motion in general F 16 H; pistons, piston-rods, cylinders, for engines in general F 16 J)
 

Notes

(1)

 This subclass covers, with the exception of the matter provided for in subclasses F 01 C to F 01 P:
 

-

 engines for elastic fluids, e.g. steam engines;
 

-

 engines for liquids and elastic fluids;
 

-

 machines for elastic fluids;
 

-

 machines for liquids and elastic fluids.

 Attention is drawn to the Notes preceding class F 01, especially as regards the definitions of "steam" and "special vapour".

 

 

 
 

 1
