Class 100
PRESSES
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+).
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.
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+.

Apparatus acting within a storage chamber building to compact
fodder material confined by the floor and walls of the
building.
(1) Note. The devices in this and the subclasses indented
hereunder are usually employed while the silo is being filled
and thus act to compact successively added increments of
material against the mass already compacted within the silo.
As the silo thus fills, the compacter acts always on the top
of the material as it rises within the silo. This requires
that the compacter be so connected to its actuator means that
the operation is continuous despite the changing level.
(2) Note. The storage chamber is usually round in cross
section. This permits the use of a compacter moving
circularly about an axis normal to such cross section and
having a uniform radius of action. Furthermore, the round
wall presents a continuous surface which may be used to guide
such a circularly moving compacter.

(1) Note. In the devices here classified the material is

openings generally by the platen causing compression or the

the material from one place to another where the movement is
incidental to the compressing operation see the Search This

acutated by the weight of the material between the platens,

the compressive force. Additionally a movable platen may

platen.
(2) Note. The material may be pressed progressively in these
presses. That is, successive increments are compressed which
