Total Claims: 7
Claim 1
Independent Claim
249 words
A livestock watering system comprising, a concrete waterer housing having a lower end and an upper end, said housing having formed therein a hollow compartment with an open end at said lower end of said housing; a pipe circuit having a portion thereof embedded in said housing, said pipe circuit having first and second terminal ends extending within said compartment and an animal water outlet extending exteriorly of said housing at a point spaced above the ground; said outlet having a valve therein which is movable between open and closed positions and which is biased towards its closed position, said valve being yieldably movable to its open position in response to pressure from the livestock being watered. a source of water above freezing temperature; a first pipe connected to said source and extending from below the frost line of the ground upwardly into said compartment where it is connected to said first terminal end of said pipe circuit, a second pipe connected to said second terminal end and extending downwardly therefrom below the frost line of the ground; vertical underground pipe housing means in communication with said open end of said compartment and extending downwardly below the frost line of the ground; said housing means surrounding said first and second pipes; pump means for providing continuous flow of water from said source through said first pipe, said pipe circuit, and said second pipe whereby heat energy in said circulating water will deter freezing of water in said water lines.
Claim 2
Dependent Claim
249 words
A livestock watering system comprising, a concrete waterer housing having a lower end and an upper end, said housing having formed therein a hollow compartment with an open end at said lower end of said housing; a pipe circuit having a portion thereof embedded in said housing, said pipe circuit having first and second terminal ends extending within said compartment and an animal water outlet extending exteriorly of said housing at a point spaced above the ground; said outlet having a valve therein which is movable between open and closed positions and which is biased towards its closed position, said valve being yieldably movable to its open position in response to pressure from the livestock being watered. a source of water above freezing temperature; a first pipe connected to said source and extending from below the frost line of the ground upwardly into said compartment where it is connected to said first terminal end of said pipe circuit, a second pipe connected to said second terminal end and extending downwardly therefrom below the frost line of the ground; vertical underground pipe housing means in communication with said open end of said compartment and extending downwardly below the frost line of the ground; said housing means surrounding said first and second pipes; pump means for providing continuous flow of water from said source through said first pipe, said pipe circuit, and said second pipe whereby heat energy in said circulating water will deter freezing of water in said water lines.
Claim 3
Dependent Claim
42 words
The system of claim 1 wherein said passageway and said interior compartment have horizontal cross-sectional areas sufficiently large so that heat from the ground will rise upwardly into said interior compartment to help prevent freezing of the water in said valve means.
Claim 4
Dependent Claim
13 words
The device of claim 1 wherein said water outlets are nipple valve elements.
Claim 5
Dependent Claim
28 words
The device of claim 1 wherein said housing has an access opening in the side thereof for communication with said compartment to permit access to said terminal ends.
Claim 6
Dependent Claim
34 words
The device of claim 1 wherein said housing includes a step element on its sides to support the front feet of an animal to permit easy access by the animal to said water outlet.
Claim 7
Dependent Claim
89 words
The system of claim 1 wherein a third pipe interconnects said first and second pipes below the frost level of the ground for permitting water to pass directly from said first pipe to said second pipe without passing through said pipe circuit in said waterer housing; said third pipe having a restriction therein which limits the amount of water passing therethrough so that part of the water from said first pipe passes through said pipe circuit and part of the water from said first pipe bypasses said pipe circuit.
