Class 425
PLASTIC ARTICLE OR EARTHENWARE SHAPING OR TREATING:
APPARATUS
Class Definition:
This is the generic class for:
1. Apparatus including a molding surface which either shapes
a fluent or bulk material, which material has plasticity as a
property, into a self-sustaining article or preform of
desired shape or which reshapes or resizes a plastic or
"green" preform or product, not provided for elsewhere.
2. Apparatus for shaping of molten materials including
metal, but excluding glass, where no molding surface is
employed, e.g.., by melt comminution or spheroidizing.
3. Apparatus for treating (e.g.., vulcanizing, etc..), a
product made by the apparatus of this class, not provided for
elsewhere.
4. Apparatus for randomly depositing and bonding (uniting)
particulate material, not provided for elsewhere.
5. A combination of apparatus of this class with any diverse
working or treating apparatus which combination is not
provided for elsewhere.
(1) Note. Caveat relating to administration of this class.
Only the assignment of "original" copies of patents issued
after 1934 are to be used as evidence of appropriate
classification within the class.
(2) Note. Class 425 does not provide for a product made by
the apparatus of the class. A specific article is classified
with the respective art class to which it belongs, (e.g.., a
rubber glove is provided for elsewhere).
SEE OR SEARCH THIS CLASS, SUBCLASS:

simultaneous extrusion of a drop of liquid and a drop of
fluent but hardenable encapsulating material.
77 for an ultra high pressure generating device disclosed
for use in changing or controlling chemical or physical
properties of a material (e.g.., diamond maker, etc..).
87 see the notes and compare with the class for dispensing,
some of which subclasses provide for means to dispense
semi-solids, (e.g.., toothpaste, putty, etc..), where there
is no intent that a dispensing orifice produces a
self-sustaining preform having a shape that is reflected in a
