Anti-pollution cattle feeding stations

Claim 2

An animal feeding station, comprising a fence enclosing an area, at least one feed station adjoining said fence, a layer of asphalt co-extensive with said area, a layer of particulate material overlying said layer of asphalt over substantially its entire layer, a layer of perforated thin sheet steel lying flat on said layer of particulate material, a sump, and pipe means for conveying liquid produced by said animals from said particulate material to said sump, said pipe means being located below said layer of perforate thin sheet steel but above said layer of asphalt.

Claim 3

The combination according to claim 1, wherein said particulate material is primarily gravel.

Claim 4

The combination according to claim 1, wherein said last means includes perforated pipes laid above said layer of asphalt, said pipes communicating with all areas of said station and being sloped sufficiently to provide rapid drainage from said particulate material to said sump for all areas of said station.

Claim 5

A feeding station for animals, comprising a fence defining the boundaries of said feeding station, at least one feed bunker adjoining said fence, a layer of perforated steel sheet material substantially covering the entire area within said fence, a quantity of particulate non-absorbent solid material underlying and supporting all said sheet material, and means for collecting liquid deposited on said layer of perforated steel sheet material from said particulate solid material.

Claim 6

A feeding station for animals, comprising a fence defining the boundaries of said feeding station, at least one feed bunker adjoining said fence, a layer of perforated steel sheet material substantially covering the entire area within said fence, a quantity of particulate non-absorbent solid material underlying and supporting all said sheet material, and means for collecting liquid deposited on said layer of perforated steel sheet material from said particulate solid material.

Claim 7

An animal station, comprising a fence enclosing said station, at least one feed bunker adjoining said fence, a base lamina underlying the area defined by said fence and a layer of non-liquid-absorbent particulate matter supported by said base lamina, a layer of perforated thin sheet steel plate supported on said particulate matter and extending over the area defined by said fence, the perforations of said plate encompassing at least 25 percent of the area of said plate, a lagoon, and perforated collection pipes distributed within said particulate matter, wherein said base lamina, pipes and plate are all sloped to facilitate gravity flow of liquid to said lagoon, cisterns communicating directly with said lagoon, pipe means interconnecting said cisterns with said lagoon, and means providing direct access from said particulate matter to said lagoon, whereby plural modes of run-off of liquid matter can occur from the upper surface of said plate to said lagoon, viz. directly over the surface of said plate, directly through said aggregate, and through said perforated pipes.

Claim 8

An animal station, comprising a fence enclosing said station, at least one feed bunker adjoining said fence, a base lamina underlying the area defined by said fence and a layer of non-liquid-absorbent particulate matter supported by said base lamina, a layer of perforated thin sheet steel plate supported on said particulate matter and extending over the area defined by said fence, the perforations of said plate encompassing at least 25 percent of the area of said plate, a lagoon, and perforated collection pipes distributed within said particulate matter, wherein said base lamina, pipes and plate are all sloped to facilitate gravity flow of liquid to said lagoon, cisterns communicating directly with said lagoon, pipe means interconnecting said cisterns with said lagoon, and means providing direct access from said particulate matter to said lagoon, whereby plural modes of run-off of liquid matter can occur from the upper surface of said plate to said lagoon, viz. directly over the surface of said plate, directly through said aggregate, and through said perforated pipes.
