CLASS 119,	ANIMAL HUSBANDRY
Click here for a printable version of this file

SECTION I - CLASS DEFINITION

This class provides for methods or apparatus for the propagation, rearing, training, exercising, amusing, feeding, milking, grooming, housing, controlling, handling, or general care of a living animal unless provided for elsewhere.

(1) Note. The word "animal" is used in its generic biological meaning of a living sentient multicellular organism and is applicable to insects, fish, fowl, mammals, and other members of the animal kingdom.

(2) Note. This class is subdivided into:

(a) an array of specified animal culturing subclass groups, the common bond within each group being determined by the particular kind of animal that is the subject of the invention;

(b) an array of subclass groups directed to a method or apparatus for obtaining milk from an animal other than a human; and

(c) a number of subclass groups, the common bond within each group being determined by the function or mode of operation rather than the particular creature to which the invention is applied. The groups mentioned in (c) may include subject matter specifically limited in use to a human or to fowl, and patents directed to said specific uses are classified in subclasses having a distinctive title which provides for the respective human or fowl specific use. It should be noted that the subclass(es) that specifically provide for a human use are the only areas in this class providing for a human application, and since these subclasses are the residual areas for human application not otherwise provided for, the definitions of these subclasses are strictly limited. The outside classes listed in the search notes of both the class definition and the subclass(es) relating to a human should be exhausted before placement of a patent relating to a human application in this class.

(3) Note. A method provided for in this class is appropriately classified in a subclass specifically providing for the method or, absent a specific method subclass, in a subclass providing for the apparatus of this class used in the method.

(4) Note. A method of making an apparatus of this class is excluded from this class, and may be found in an appropriate manufacturing class.

SECTION II - LINES WITH OTHER CLASSES AND WITHIN THIS CLASS

FOR SUBJECT MATTER RELATED TO MILKERS

Class 60, Power Plants, has pulsators distinguished from Class 119 and Class 137 Fluid Handling, subclasses 103+, pulsators or fluid distributors in that the former do not relate to through-flow mechanisms but rather effect the pulsing of a confined body of fluid, the same body of fluid, for example, operating upon a pressure responsive mechanism. Milking machine pulsators are broadly construed as valving arrangements which cyclicly control fluid flowing under pressure and not involving the same body of fluid. See References to Other Classes, below, labeled as having other subject matter related to milkers

"Pump elements" of this class (119) permit through flow of fluids but lack, in general, valving ingress except that provided by the nature of the cow being milked.

BROODER:

This subclass is indented under the class definition. Subject matter including a small, warmed chick housing chamber, provided with a hover, hover chamber, or canopy to perform the function of a mother fowl in providing shelter and warmth to the chicks.

(1) Note. For original classification of a patent in this and indented subclasses, there must be claimed some structure, in addition to a heating or ventilation system, which particularizes the device for the confinement or protection of the chicks. Merely calling a device a brooder is insufficient disclosure for placement in this subclass. Examples of particularizing structures are attraction lights, dropping boards, and spacers, or other antismothering devices.

(2) Note. The hover structure is a component within the brooder chamber constructed of a flexible material, usually feathers. The hover is designed to lie in close proximity to the chicks, so that in brushing against their backs, it provides not only warmth but a sense of security.
