Abstract: A high pressure misting nozzle is disclosed having a nozzle stem body with a fluid inlet and a first chamber in communication with the fluid inlet, a fogger nozzle attached to the nozzle stem body, the fogger nozzle having a nozzle orifice and a second chamber in communication with the nozzle orifice and the first chamber, a valve member movably located in the first chamber and movable between a closed position preventing fluid communication between the fluid inlet and the first chamber, and an open position which allows fluid communication between the fluid inlet and the first chamber, and a nozzle pin movably located in the second chamber, the nozzle pin having fluid metering notches and being freely movable between a first position in which it is displaced away from the nozzle orifice, and a second position in which it is located adjacent to the nozzle orifice, the fluid entering the second chamber urging the nozzle pin toward the second position.

Abstract: A poultry feeder having an adjustment mechanism which adjusts the relative positions between the feeder tower and the feeder bowl to control the amount of feed entering the bowl that is readily adjustable, and, at the same time, enables the feeder bowl, the grill and the adjustment collar to freely rotate relative to the feeder tower to prevent damage to the adjustment mechanism when the grill and/or the bowl is contacted by the feeding birds. A lower edge of an adjusting collar rests on a shoulder portion of the feeder tower when the poultry feeder is suspended above floor level. The relative positions between a bottom of the feeder tower and the feeder bowl is adjustable in a plurality of discreet positions. Each of the plurality of discreet positions provides a different clearance between the bottom of the feeder tower and the bowl, thus controlling the amount of feed which may enter the bowl from the feeder tower.

Abstract: A liquid feeding nipple is disclosed for feeding liquids to fowl having a hollow housing, a valve seat insert located in the housing, the valve seat insert having a first liquid passage, a housing cap on a second end of the housing, the housing cap having a second liquid passage, and a valve member movably located within the housing so as to be movable between a closed position, in which liquid communication between the first and second liquid passages is prevented, and an open position which enables liquid communication between the first and second liquid passages. The liquid feeding nipple also has a trigger pin with a head in contact with the valve member and a stem extending from the housing. The stem has a first flow control portion adjacent to the head and a second flow control portion adjacent to the first flow control portion such that the cross-sectional area of the second flow control portion is less than that of the first flow control portion.

Abstract: A ventilation control system is disclosed for a building having an elongated ceiling vent opening, the system having a vent door, spaced apart brackets pivotally supporting the door on the building structure adjacent to the ceiling vent opening such that the door is movable between closed and opened positions, and an actuating mechanism for moving the door between the closed and opened positions. The vent door has an elongated door casing of plastic material having a hollow interior and opposite side walls, a support member located in the hollow interior of the door casing adjacent to each of the opposite side walls and a foam material substantially filling the hollow interior of the door casing. The door casing may be extruded from plastic material and has integrally formed outwardly extending sealing members which engage the building structure when the vent door is in the closed position to seal the vent opening.

Abstract: An insulated watering system is provided for fowl, animals or the like in which a length of pipeline is defined by several groups of watering pipes with each group of watering pipes being of a different wall thickness and having greater heat-insulating efficiency in the direction of water flow. The pipes are preferably formed from foamed polymeric/copolymeric material, such as polyvinylchloride, and each includes an interior cylindrical closed cell core sandwiched between noncellular skins or plies. The exterior diameters of all watering pipes are identical, but the interior diameters of the various groups decrease in the direction of water flow. In this fashion, a larger wall thicknesses of the pipes effectively insulate the lesser volume of water flowing through the water line along downstream portions thereof.

Abstract: A watering system for poultry, small animals or the like including a plurality of elongated stabilizing anti-roosting members in longitudinal alignment with each other and interconnected by slidable connectors, a plurality of interconnected watering pipes below the stabilizing members, clips for connecting the stabilizing members to the watering pipe and a suspension system for suspending the overall watering system relative to a supporting surface. The clip for connecting the stabilizing members to each other in generally of an inverted V-shape configuration and the clip for securing the watering pipes to the stabilizing members is of a generally C-shaped configuration.

Abstract: A drinker for feeding liquid to fowl and/or small animals includes a housing having an outlet through which liquid/water flows under the control of a valve operated by a drinker 10 which is actuated by the fowl and/or small animals. The water outlet and particularly the pin is supported above an uppermost top wall of a wire cage which prevents inadvertent/accidental operation of the pin to prevent water leakage. An inlet is directed into an associated water pipe from above with an associated outlet thereof being spaced above a lowermost portion of the water pipe to preclude accumulated sediment from entering the drinker and causing the valve to remain in its open position.

Abstract: A pressure regulator includes a flexible diaphragm which sets-off a liquid chamber having an inlet and an outlet for respectively introducing liquid into and discharging liquid from the liquid chamber under the control of an associated valve through an actuator operated by the movement of the diaphragm. The valve is carried by a coupling which is connected to the housing inlet which, upon the uncoupling of the coupling, allows inspection and/or repair of an associated valve seat or the actuator through the pressure regulator inlet.The pressure regulator can be cleaned or flushed by a novel method which includes uncoupling the coupling from the liquid inlet and reversing the connection with an associated standpipe outlet and thereafter reopening the liquid inlet valve. Liquid enters the liquid chamber through the standpipe outlet and discharges the liquid chamber through the liquid outlet thereby flushing the liquid chamber in a thorough and effective manner.

Abstract: A nipple drinker particularly adapted for feeding liquid to fowl and/or small animals which includes a passage, a ball valve closing the passage when seated on at least one valve seat, and a ball valve actuating stem having a head and a pin, the head having a concave surface and a through bore opening therethrough, and an exterior surface of the pin having at least one water flow channel whereby both small and large fowl and/or animals can actuate the stem to unseat the ball valve in proportion to the force applied to the stem which not only provides proportional water flow but also assures automatic self-cleaning or flushing of the recess.
