SECTION III - GLOSSARY
Terms in the definitions of this class followed
by an asterisk(*) will be found to be defined in this section.
ACCESS
The term "access" is intended to include
a cutting means which (a) makes an incision (usually at a point
adjacent either the stem or tip of the food) for the purpose of allowing
the same means and/or another means to separate the core-pit* from
the interior of the food; or, (b) impales the food (and, the place
of entry of the impaling means frequently is used for the same purpose
as the incision in (a), immediately above); or, (c) halves the food
(and, once the food is "halved", an easier "access" is
obtained to separate the core-pit, seeds, inner membranes, etc.)
BLOSSOM-END
This expression relates to the surface area of food at
the location of the natural attachment to the food of the flower
or calyx of food such as a cherry or strawberry and may also include
a small portion of adjacent skin; the expression is arbitrarily
extended to include the tip or root of food such as a turnip or
potato.
CORE-PIT
That portion of an article of food that is located in
and around the geometrical center of the food; however, the outer
periphery of the core-pit is NOT necessarily equidistant for the
outer periphery of the food, (e.g., a generally ellipsoidal "pit" in
a generally spherical peach). Further, in some varieties of food
(e.g., a relatively small variety of apple) a drilling or punch-die
type means which may remove a substantially right circular cylinder
section, when aligned with the stem-blossom axis of the apple, will
usually remove not only the seed pocket but also that portion of
the apple containing matter connected to both the stem and blossom
ends of the apple. Thus, the core-pit portion may include a central portion
only, or a central portion plus a right-circular-cylinder section
containing the central portion.
CORE-PIT
This expression usually precedes the word "means",
and is intended to comprehend a "mechanical treatment" which
contacts all or a portion of the core-pit and then severs, tears
away, separates, and/or removes the core-pit from the remaining
portion of the food.
DISJOIN (DISJOINING)
These expressions are used to indicate that one portion of
a naturally occurring article of food is detached or disunited from
an immediately adjacent portion of the food without necessarily
being spatially separated to a significant extent. For example:
rolling, with some slight pressure, a hard-boiled fowl egg will
disunite at least part of the bond between the outer shell* and
the interior of the egg; however, unless the shell is totally removed,
the membrane between the shell and the interior egg portions keeps
the shell attached. Thus, at least portions of the shell have been
disjoined from the inner portions although the same, or other portions
of the shell, have not been spatially separated from the inner portions.
EDIBLE
An object that is subject to consumption by an human
or animal by chewing or masticating prior to swallowing.
FOOD
A man-made or naturally-occurring discrete article consumable
by animals or humans for nourishment.
GRAIN
This term is interpreted to include those seeds to which the
term is ordinarily applied, e.g., wheat, oats, cottonseed, corn,
coffee beans, barley, etc., and to exclude larger vegetables such
as beets, nuts, potatoes, etc.
HULL or HULLING
These expressions are treated as being species of skin* disjoining*;
however, an exception is recognized, as follows: Grain-hulling equates
a covering of dirt or similar impurities, with the naturally occurring
outer covering of grain*.
REMOVE
To spatially separate significantly one portion of food from
another.
SEED
A discrete article, constituting a propagative part of
a naturally-occurring edible food, usually found in or near the
core-pit area. As to human consumption, it is frequently "waste";
but, as to the reproduction of the species, it is essential.
SHELL
Shell includes those outer coverings of articles of food which
fracture upon impact, as distinguished from those outer coverings
that yield upon impact. Prime example of foods having fractile and/or
fracturable outer coverings are fowl eggs and nuts.
SKIN
That portion of the outer periphery of an article of
food that is dissimilar with respect to the inner portion of the food
in at least one (and usually several) of the following respects:
color, consistency, density, firmness, flexibility, hardness, texture
("rough" vs. "slick" to the touch),
and toughness (resistance or lack of resistance to "tearing").
STEM-END
This expression relates to the surface area of food at
the location of the natural attachment to the food of a stalk, stem,
branch, vine or cap that supports an article of food such as a cherry
or strawberry and may also include a small portion of the adjacent
skin; the expression is arbitrarily extended to include the area
of attachment of the sprout, leaf, stalk or foliage of food such
as a potato.
STEMMING
This expression is arbitrarily assigned as being generic to
the separation of items such as a blossom, leaf, root, tip, or similar
portion of a naturally occurring food, in addition to connoting
the separation of a stem.

(1)
Note. This subclass is a locus for reciprocating, solid (nonperforated)
grain-hulling members.
(2)
Note. Excluded from this subclass are mere tumbling devices
(i.e., rotary drums or other moving receptacles which present no
abrasive or other material removing surface to the grain) for effecting
mutual abrasion only between the grains for hulling or cleaning,
such devices being classified in the appropriate subclasses of Classes
51, 366, or other appropriate classes in accordance with the line
between those classes. However, receptacles, whether moving or stationary,
when provided with relatively movable grain contacting members which
move the grain in the receptacle for the purpose of removing the
husk or adhering impurities (see (3) Note.), are provided for in
this class even though the action on the grain is limited to mere
mutual abrasion. Combinations, which include both mere mutual abrasion
by tumbling in a moving receptacle and the use of an abrading or
other material removing surface, are provided for in this and the
indented subclasses.
(3)
Note. Most of the devices classified in this or the indented
subclasses are for the purpose of removing husks, skins, or other
naturally occurring integuments from grains. However, because of
the similarity of their structure to hullers, cleaners (to remove
adhering impurities) are included when the cleaner is of such a
nature as to subject the grain to an appreciable rubbing, abrasion
or impact action by a solid work treating surface or agent. Cleaners
not involving appreciable abrasion or impact action will be found
in the generic cleaning Class 134, Cleaning and Liquid Contact With
Solids, or some other cleaning class according to the notes appended
to the class definition of Class 134.
Brushing, Scrubbing, and General Cleaning,
subclasses 3.1+ for grain cleaners employing the instrumentalities
provided for in that class, e.g., brushes and wipers. See subclass
620 of this class (99) for hullers employing brushes or wipers.
Solid Material Comminution or Disintegration, for grain comminuting devices having structure similar
to the devices classified herein and for combinations of grain hullers
of the type classified here, with comminutors (see
subclasses 7 and 101.01 of that class). Since most of the hullers
classified here inherently divide the husk or adhering impurities
into a number of pieces in the process of removal from the grain,
only such devices as effect the division of the grain body (endosperm)
into a plurality of parts should be considered comminutors or comminutor-huller
combinations for Class 241.
Agitating,
subclasses 219+ for movable mixing chambers, and subclasses 241+ for
stationary mixing chambers with movable stirrers having general
utility as described in (2) Note above.
Abrading, for an abrading process or apparatus of general
application. For example, included in Class 451 is a grain tumbling
device which presents no abrasive or other material removing surface
to the grain wherein abrading is effected by mutual engagement of
the grains with each other. However, note that a grain container
that is either stationary or moving is included in Class 99 when provided
with a grain contacting member which moves the grain in the container
for the disclosed purpose of removing the husk or adhering impurities,
even if using an abradant.
