Abstract
Abstract A recirculating animal waterer is disclosed. In one embodiment, the waterer includes a supply conduit which extends from a remote water source underground at a level below the frost line to a first junction located inside a waterer stand. A first nipple extends from that first junction and terminates outside the stand. A cross-over conduit extends from the first junction to a remote second junction, also located inside the waterer stand. A second nipple extends from that second junction to a point outside the stand. A return conduit extends from the second junction back to the first junction. This return conduit includes a heatable section. A heater is mounted adjacent the supply conduit heatable section. If desired, a thermostat can be located adjacent the second junction to provide intermittent heater operation. In another embodiment, additional nipples extend from the stand, and water conduits provide an endless, recirculating flow of water past each nipple.

Claims Analysis
Total Claims: 24
Claim 1
Independent Claim
117 words
A recirculating animal waterer, comprising, in combination, a water supply conduit adapted to extend from a water source to a first junction, a first nipple extending from the first junction, a cross-over conduit extending from the first junction to a remote second junction, the first and second junctions being mounted at substantially the same hydraulic levels, a second nipple extending from the second junction, a return conduit separated from the supply conduit and extending from the second junction back to the first junction, and a heater mounted adjacent the return conduit whereby to heat water in the return conduit and encourage convective, endless water flow in the waterer without directly heating water in the water supply conduit.
Claim 2
Dependent Claim
117 words
A recirculating animal waterer, comprising, in combination, a water supply conduit adapted to extend from a water source to a first junction, a first nipple extending from the first junction, a cross-over conduit extending from the first junction to a remote second junction, the first and second junctions being mounted at substantially the same hydraulic levels, a second nipple extending from the second junction, a return conduit separated from the supply conduit and extending from the second junction back to the first junction, and a heater mounted adjacent the return conduit whereby to heat water in the return conduit and encourage convective, endless water flow in the waterer without directly heating water in the water supply conduit.
Claim 3
Dependent Claim
41 words
A recirculating animal waterer according to claim 1 including a housing member, the first and second nipples each extending from their respective junctions through the housing to terminal points outside the housing so as to provide nipple access to thirsty animals.
Claim 4
Dependent Claim
28 words
A recirculating animal waterer according to claim 1 including a thermostat electrically connected to said heater so as to cause said heater to operate on an intermittent basis.
Claim 5
Dependent Claim
16 words
An animal waterer according to claim 3 wherein said thermostat is located adjacent said second nipple.
Claim 6
Dependent Claim
26 words
A recirculating animal waterer according to claim 1 including water shut-off means located in said supply conduit between said first junction and said remote water source.
Claim 7
Dependent Claim
24 words
An animal waterer according to claim 1 wherein said return conduit includes a heatable section having a section inlet located below a section outlet.
Claim 8
Dependent Claim
22 words
A recirculating animal waterer according to claim 2 wherein said first and second junctions are mounted on opposite sides of said housing.
Claim 9
Dependent Claim
45 words
A recirculating animal waterer according to claim 1 wherein said water supply conduit includes a single line extending from a position below a soil frost line to said first junction, and wherein said first junction is located at a position above said soil frost line.
Claim 10
Dependent Claim
47 words
A recirculating animal waterer according to claim 1 or 2 wherein at least one of said nipples includes a hollow cylinder having a downstream end, the downstream cylinder end defining an anti-freeze-up slot extending axially inwardly in an upstream direction from the downstream cylinder nipple mouth end.
Claim 11
Dependent Claim
140 words
A recirculating animal waterer according to claim 1 or 2 wherein at least one of said nipples has an upstream end adapted to receive water, and a downstream mouth extending axially toward and terminating at a downstream end, the nipple also including a valve member carried in the body member and having a stem adapted to be canted from a closed, water-flow-halting position to an open, water-flow-permitting position, the nipple body mouth taking the shape of a hollow right cylinder through which a bevel plane has been passed, thereby exposing a limited side portion of the valve member stem to canting motion by animal biting action, but prohibiting the animal from grasping the stem during biting action, the mouth defining an anti-freeze-up slot in the cylinder wall extending axially inwardly in an upstream direction from the downstream nipple mouth end.
Claim 12
Dependent Claim
146 words
A recirculating animal waterer, comprising, in combination, a walled housing, a supply conduit extending from a water source into the housing and terminating at a first junction, a first nipple extending from the first junction through the housing wall and terminating outside the housing, a conduit extending from the first junction to a remote second junction, a second nipple extending through the housing wall and terminating outside the housing wall, at least one additional conduit extending from the second conduit to an additional downstream junction point, a return conduit separate from the supply conduit and extending at least indirectly from the additional junction point back to the first junction, and a heater positioned in the housing to heat water in the return conduit so as to cause water to recirculate through the conduits except the supply conduit and past the nipples in a substantially continuous flow.
Claim 13
Dependent Claim
146 words
