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.
