DEFINITION

Classification: 100/269.01

Fluid pressure actuation:

(under subclass 214) Apparatus in which the means to move an opposed pressure surface (i.e., platen) includes an expansible working chamber, and means to admit fluid under pressure into the working chamber to cause expansion of the working chamber.

SEE OR SEARCH THIS CLASS, SUBCLASS:

170, for a roll-type concurrent conveying and pressing press having fluid pressure means for yieldably mounting at least one of the rolls.

SEE OR SEARCH CLASS

29, Metal Working,

252, for a pulling or pushing assembling or disassembling device having a fluid operator.

60, Power Plants, 325+, (and particularly 533+) for an hydraulic-type motor not combined with press structure, and see the reference to Class 60 in the class definition of Class 100 for a statement of the line.

72, Metal Deforming,

429+, for means to drive a tool of a metal shaping machine, and see the notes thereto.

83, Cutting,

137, for cutting apparatus embodying a fluid pressure actuated stripper; subclasses 375, 390, 460, and 461 for cutting apparatus with fluid pressure actuated work clamp; and subclass 639 for a cutting tool reciprocated by fluid pressure means.

91, Motors: Expansible Chamber Type, appropriate subclasses for expansible chamber motors not combined with press structure, and see the reference to Class 91 in the Class Definition of Class 100 for a statement of the line.

147, Coopering,

9, for a machine having an hydraulic or steam press for forcing a hoop upon a barrel.

164, Metal Founding,

212, for a fluid pressure operated sand mold press, and subclasses 312+ for a fluid pressure operated metal injection machine.

254, Implements or Apparatus for Applying Pushing or Pulling Force,

93+, for a fluid pressure actuated implement (other than a power applying element or machine) for applying a pushing or pulling force to an object (e.g., jack, extractor, tensioning apparatus, etc.). 269, Work Holders,

20+, for a device having fluid means to grip work while being treated. See section VIII under the class definition of Class 269 for the line with Class 100.

408, Cutting by Use of Rotating Axially Moving Tool,

63, 99, and 130 for a drill press in which the motor making the tool and work move relative to one another along the axis of relative rotation is operated by fluid pressure.

417, Pumps, appropriate subclasses for a pump, per se, for generating pressure for a fluid motor actuated press.

418, Rotary Expansible Chamber Devices, for a rotary expansible chamber-type pump, per se.

425, Plastic Article or Earthenware Shaping or Treating: Apparatus,

389+, for a preform reshaping or resizing or vulcanizing means utilizing a fluid pressure actuated diaphragm as a press surface, and subclass 417 for a press forming apparatus including an expansible male-shaping member.

452, Butchering,

43, for a sausage stuffer in which a reciprocating piston is actuated by a fluid motor.
