DEFINITION

Classification: 241/270

(under subclass 262) Apparatus in which the reciprocation of the comminuting surface is in a vertical straight-line path.

(1) Note. Most of the devices classified in this group are those ordinarily known as "stamp mills".

SEE OR SEARCH THIS CLASS, SUBCLASS:

149+, and 165, for plural devices of this type.

205, for devices having the characteristics of this group in which the reciprocating surface is given a rotary motion on the comminuting stroke.

263, for vertically reciprocating surfaces moving parallel to a cooperating surface. SEE OR SEARCH CLASS

74, Machine Element or Mechanism, appropriate subclasses, for actuating devices of the type there provided for in which no claim is made to a significant comminutor combination. See the notes in the class definition.

81, Tools,

463+, and see the notes thereto for other impact tools.

91, Motors: Expansible Chamber Type, appropriate subclasses, for actuating devices of the type there provided for in which no claim is made to a significant comminutor combination. See the notes in the class definition.

100, Presses,

214+, for reciprocating presses not elsewhere provided for.

384, Bearings, for vertically reciprocating stems of stamp mills where no significant structure of the comminutor is included. See the line with Class 384 in the notes to the class definition.

418, Rotary Expansible Chamber Devices, appropriate subclasses, for rotary expansible chamber motors, per se, or in which no claim is made to a significant comminuter combination. See OPERATORS FOR COMMINUTORS and Refernces To Other Classes of the main class definition to this class (241).
