SECTION I - CLASS DEFINITION

This is the generic class for apparatus for subjecting material to compressive force by (a) causing solid surfaces to approach one another while the material is between them, (b) compelling the material to move through a constriction, or (c) by rendering a flexible member taut around the material. [For specific subclass references, see Subclass References to the Current Class, below.]

This class is the generic class for methods and apparatus for binding material with a flexible filament, strand or band.

This class includes methods in which material is pressed to compact it to a smaller volume.

This class includes methods and apparatus for pressing a lid against a receptacle.

This class includes silos combined with means to compact ensilage within them. (See subclasses 65-69).

This class includes presses with a duct or collector for liquid flowing from the material as a result of the pressing.

This class includes devices for removing from the material a cloth in which the material has been compacted.

This class (100) includes methods and apparatus for crushing hollow metal bodies such as tin cans, automobile bodies, etc. Disclosure of additional utility for bottle breaking is also included here (Class 100) while bottle breaking, per se, is in the class for solid Material Comminution or Disintegration. See the Search Class Notes below.

This class includes devices for subjecting previously associated articles to compressive force to cause them to be bonded together where no associating means is claimed.

EXPLANATORY NOTE ON SCOPE OF CLASS

Presses are employed in many arts and are classified generally according to the art to which they pertain. For the locus of various arts, reference may be made to the Index to the Manual of Classification. In Lines With Other Classes, Combined Pressing Elsewhere Classified and Binding and Pressing Elsewhere Classified, hereof, are listed arts in which pressing is common or in which subclasses have been established relating to it.

Class 100 has heretofore gathered presses relating to such arts as baling, bundling, copying, expressing liquids from solids, and packing. The art so gathered has been employed to establish this generic classification of presses.

Since it is not desirable to withhold from use those portions of the reclassification which can be completed and handled as a unit, the reclassification is established even though many inventions relating to the subject matter are represented herein only by search notes to other classifications.

SECTION II - LINES WITH OTHER CLASSES AND WITHIN THIS CLASS

Class 100 is the generic class for apparatus for pressing particulate material. Class 264 is the generic class for corresponding methods; for the line between these classes see paragraphs under Lines With Other Classes and Within This Class of the class definition of Class 264.

COMBINED PRESSING ELSEWHERE CLASSIFIED

This class provides, in subclass 102, and in the various subclasses preceding it for pressing in combination with other features. Nearly all pressing elsewhere classified includes not only pressing, per se, but in combination with other devices or steps. Where other classes set out subclasses directed to combinations of pressing with other features, which combinations relate to those appearing in the Class 100 schedule, suitable cross search notes to the subclasses concerned have been made.

See References to Other Classes, below, referencing this section for classes that each include pressing and have a subclass directed to combined features generally, one of which may be pressing, or a specific combination of pressing with other features and not appearing in the Class 100 schedule or of special note.

BINDING AND PRESSING ELSEWHERE CLASSIFIED

Methods and apparatus are intermixed in the art as elsewhere classified and they are included together in References to Other Classes, referencing this section.

Plastic shaping. The shaping of material by molecular flow under pressure is generically in Class 264, Plastic and Nonmetallic Article Shaping or Treating: Processes, and divided among other classes according to the nature of the material worked. Of these, Class 99, Foods and Beverages: Apparatus, and Class 426, Food or Edible Material: Processes, Compositions, and Products, are generic to food material, and Class 72, Metal Deforming, as to metal. Class 419, Powder Metallurgy Processes, for making articles from particulate material including metal particles. See the definitions of these classes for the distribution of related art.

The compaction of particulate material into a definite shape wherein at least some of the particles maintain their identity in the product is classified in Class 100 and Class 264. For the line, see the definitions to Class 264, particularly subclasses 109-128.

However, compressing the material for the purpose of baling or forming a solid, compact, self-contained bundle is considered treatment of matter to change its shape or condition and so would go beyond Class 414 subject matter and cause classification in Class 100 even if associated with a vehicle.

(1) Note. In the devices here classified the material is moved from one position to another to transport it between openings generally by the platen causing compression or the pressure surface. For devices in which there is movement of the material from one place to another where the movement is incidental to the compressing operation see the Search This Class, Subclass notes below. See the Search Notes for a press acutated by the weight of the material between the platens, that is, the material resting on a platen and falling from one location to another causes the movable platen to exert the compressive force. Additionally a movable platen may transport the material into contact with the stationary platen.
(2) Note. The material may be pressed progressively in these presses. That is, successive increments are compressed which may be forced together into one mass or may have a distinct line of demarcation maintained between them.
