(under subclass 38) Apparatus in which the movement of a fluid by which the material is suspended is employed to effect the comminution of the material.
(1) Note. The distinction between the patents included in this subclass and those in the other fluid application subclasses, is that the devices herein employ the movement of the fluid, viz., its kinetic energy, to effect the comminution of the material to which it has been applied.
(2) Note. Comminuting devices which project the material against a surface without supporting it on a moving fluid current are not included herein. Numerous devices of this type will be found elsewhere in this class, see particularly subclasses 91 and 274+.

91, see (2) Note above.
185.5, through 197, and the notes thereto, for apparatus in which material is subjected to impact by rotary members but in which there is no substantial suspension of the material in a moving fluid current. 274, see (2) Note. above.
