The trough set forth in claim 2 wherein: said insulating means comprises a thermosetting plastic.

Claim 5

The trough set forth in claim 2 wherein: said insulating means comprises a urethane material.

Claim 6

The trough set forth in claim 2 wherein: the ends of said legs are bifurcated, and said flange is mounted between the portions of said bifurcated ends of said legs.

Claim 7

The trough set forth in claim 5 wherein: said flange is molded to the ends of said legs.

Claim 8

The trough set forth in claim 1 in further combination with: a water inlet pipe extending along at least a part of the length thereof between said legs below the walls forming the cavity, coupling means mounted to extend through the walls of said cavity, and a float valve connected to said coupling means for controlling the flow of water into said trough.

Claim 9

The trough set forth in claim 7 in further combination with: an overflow pipe mounted within said cavity and arranged to extend through the bottom thereof for connection to a drainage system.

Claim 10

A trough for livestock comprising: a molded body member, the walls of which define an elongated closed-ended concave cavity extending along its length, said walls of said cavity at the periphery of the opening outlining said cavity being turned back on themselves to define leg means for supporting the trough, said leg means and the walls of said cavity forming between them a pocket extending around the cavity, and a flange mounted adjacent the end of said leg means and extending laterally and inwardly of said trough for supporting said trough on the top of a platform, the end of said leg means being arranged to fit around the periphery of a part of the platform.

Claim 11

A trough for livestock comprising: a molded body member, the walls of which define an elongated closed-ended concave cavity extending along its length, said walls of said cavity at the periphery of the opening outlining said cavity being turned back on themselves to define leg means for supporting the trough, said leg means and the walls of said cavity forming between them a pocket extending around the cavity, and a flange mounted adjacent the end of said leg means and extending laterally and inwardly of said trough for supporting said trough on the top of a platform, the end of said leg means being arranged to fit around the periphery of a part of the platform.

Claim 12

The trough set forth in claim 9 wherein: the end of said leg means comprises a closed loop which tightly fits the periphery of the top of the platform.

Claim 13

The trough set forth in claim 9 wherein: said flange is cemented to the end of said leg means.

Claim 14

The trough set forth in claim 10 in further combination with: fastening means extending through said legs means between their ends and said flange for fastening said leg means to the platform.

Claim 15

The trough set forth in claim 10 in further combination with: insulating means substantially filling said pocket for aiding in retaining the temperature of the substance placed in said trough.

Claim 16

A trough for livestock comprising: a molded body member, the walls of which define an elongated closed-ended concave cavity extending along its length, said walls of said cavity at the periphery of the opening outlining said cavity being turned back on themselves to define leg means for supporting the trough, said leg means and the walls of said cavity forming between them a pocket extending around the cavity, a concrete platform for supporting said trough, said platform having a flat top smaller in area than its base and positioned inwardly of the periphery of its base, the periphery of said top being of substantially the same shape as the end of said leg means whereby the end of said leg means fits tightly around the periphery of said top, and means for fastening said leg means to the periphery of said top of said platform.

Claim 17

A trough for livestock comprising: a molded body member, the walls of which define an elongated closed-ended concave cavity extending along its length, said walls of said cavity at the periphery of the opening outlining said cavity being turned back on themselves to define leg means for supporting the trough, said leg means and the walls of said cavity forming between them a pocket extending around the cavity, a concrete platform for supporting said trough, said platform having a flat top smaller in area than its base and positioned inwardly of the periphery of its base, the periphery of said top being of substantially the same shape as the end of said leg means whereby the end of said leg means fits tightly around the periphery of said top, and means for fastening said leg means to the periphery of said top of said platform.

Claim 18

The trough set forth in claim 14 in further combination with: a flange mounted adjacent the end of said leg means and extending laterally and inwardly of said trough for supporting said trough on the top of said platform.

Claim 19

The trough set forth in claim 15 in further combination with: insulating means substantially filling said pocket for aiding in retaining the temperature of the substance placed in said trough.
