Filed:

Sep 29, 1982

Appl. No.:

6/427617

Inventors:

Earl C. Thompson - Hewitt TX
Morris C. Keller - Dallas TX
Francis Rustin - Springfield MO

International Classification:

F16K 3100
A01K 700

US Classification:

1376142

Abstract:

A valve body has a larger bore and a smaller bore defining a transverse valve seat; and a plug closes the larger bore, the inner end confronting the valve seat and defining a radially enlarged valve chamber. The valve closure member comprises an enlarged head seating on the valve seat and an integral stem projecting from the discharge end of the valve. The plug has an axial recess opening toward the valve seat; and a control member comprises an enlarged head and an integral stem. A helical biasing spring is received over the control member stem; and the stem and spring are received within the plug recess to permit free axial movement over the valve closure member and free compression and expansion of the spring. The control member, which engages the closure member head to seat the closure member, has small lateral clearance with associated parts to severely restrict lateral movement of the control member and of the spring. When used with a drinker cup, the closure member stem of the valve projects axially into the cup; and a weighted valve operator disposed over the free end of the stem and extending laterally beyond the valve housing, assists newly hatched chicks to actuate the stem to open the valve.

International Classification:

A01K 3900
A01K 706

US Classification:

119 75

Abstract:

A parallel array of a lower elongated plastic water pipe, an intermediate elongated compression member, and an upper tensioned cable is supported at the ends by rigid end support members. Animal operated drinker valves, mounted within upward opening cups, are disposed in longitudinally spaced relation on the upper face of the water pipe. The entire apparatus is suspended from an overhead support by the end supports. Intermediate spacer brackets maintain the spaced relation of the pipe, compression member, and tensioned cable. Where the cable functions as an anti-roost cable for poultry, additional cable supports are mounted on the compression member and secured to the cable to maintain the spacing of these two members. In alternative form an elongated support bar of V-shaped cross-section is maintained in contiguous relation with the pipe by spaced clamps, to serve as an additional anti-sag support for the watering unit.

International Classification:

A01K 700

US Classification:

119 725

Abstract:

A drinker line consists of an assembly of prefabricated drinker sections of standardized construction. Each section includes a length of PVC pipe with a PVC pipe coupling attached to one end. A stiffening support consists of strips of sheet metal broken along its longitudinal center line to form a 60. degree. V-shaped cross section. The stiffening support includes a support bar of that construction, disposed contiguous to the pipe with the pipe partially nesting in the channel of the support, and the bar being slightly shorter than the pipe to allow for mounting of couplings at both ends of the pipe. A short bridging bar of the same stiffening construction is nested with the support bar at the coupling end of the pipe in overlapping relation with the support bar, and extending beyond the coupling end of the assembly for nesting relation with the support bar of an adjacent drinker section after assembly. The pipe, support bar, and bridging bar are secured together to form the assembled drinker section by suitable band clamps. Each drinker section includes a plurality of longitudinally spaced drinker devices, such as drinker cups secured to the pipe by poultry operated drinker valves.

Assignee:

Agri Manufacturing Corp. - Springfield MO

International Classification:

A01K 700

US Classification:

119 72

Abstract:

A water line, made up of joined sections of PVC pipe, may have any desired length. The pipe is suspended from drops at ten (10) foot intervals for example. The pipe is partially supported in plastic drop hangers having insulating and elastic properties. The drop hangers have an aperture at the upper end for connection to a drop, a laterally opening recess at the lower end to receive the pipe in snap-in relation, and a laterally opening recess intermediate its ends for receiving a metal conduit in snap-in relation. The metal conduit is formed as a continuous line and functions as a part of an electric circuit. Plastic support hangers have corresponding laterally opening recesses for the pipe and conduit. The support hangers are used as needed between the drop hangers to maintain the pipe in non-sagging relation relative to the conduit or to support a shocker wire. The pipe carries spaced animal operated drinker valves, which may be mounted in drinker cups.

International Classification:

A01K 706

US Classification:

119 725

Abstract:

A nipple waterer consists of a valve body including a base with exterior and interior bosses projecting in opposite directions from that base. A pair of spring fingers project from that base generally parallel to each other and to the interior boss. These fingers are provided with interior cylindrical recesses for engaging the cylindrical exterior of a water pipe; and the pipe is provided with a radial hole to receive the interior boss which communicates with the interior of the pipe. A bore extends axially through the two bosses and the intervening base and defines a valve chamber. A cap, secured to the exterior boss, is provided with a central hole and defines a valve seat. A valve closure member consists of a headed stem, with the stem projecting through the hole and the cap to be actuated by an animal to unseat the closure member. The closure member head is maintained against the valve seat by a helical compression spring within the valve chamber, retained therein by an internal lip at the distal end of the interior boss. In cup waterer form, a frusto-conical cup member is formed integrally with the valve body, surrounding the exterior boss and projecting closure member stem.
