Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
244 words
A trough for livestock comprising: a molded plastic 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 a pocket for receiving a supporting framework for the trough, said pocket extending around the cavity, a framework mounted within said pocket and having means at each end for mounting said member forming said cavity on two spaced upstanding pedestals, a water inlet pipe extending into one end of said cavity, valve means connected to said water inlet pipe mounted within and at one end of said cavity, cover means detachably mounted on the periphery of said cavity over said valve means and extending into said cavity for concealing said valve means from the livestock, means for detachably fastening said cover means to said trough, and insulating means for substantially filling said pocket for sealing said framework in said pocket, said cover means comprising a substantially right angular configuration having one leg formed to cover said valve means and fit against one end of said cavity adjacent said valve means and the other leg extending toward the bottom of said cavity and shaped to fit substantially the outline of the cross-section of said cavity, whereby said cover means conceals said valve means from the livestock and provides for the flow of water into all areas of said cavity.
Claim 2
Dependent Claim

Claim 5
Dependent Claim
15 words
The trough set forth in claim 3 wherein: said insulating means comprises a thermosetting plastic.
Claim 6
Dependent Claim
39 words
The trough set forth in claim 1 in further combination with a groove formed in the periphery of the outline of said cavity around said valve means for receiving the edges of said one leg of said cover means.
Claim 7
Dependent Claim
105 words
The trough set forth in claim 1 wherein: said means for detachably connecting said cover to said trough comprises a spring mounted on the underside of said cover means on said other leg of said cover means and biased to extend into a protrusion on the side of said cavity within the space concealed by said cover, and aperture means in said other leg of said cover means exposing said spring, whereby a human may reach into the space concealed by said cover means to bias said spring out of said protrusion to release said cover means from said trough to expose said valve means.
Claim 8
Dependent Claim
62 words
The trough set forth in claim 6 wherein: said spring comprises a V-shaped configuration having each of its leg members biased to extend outwardly thereof into protrusions on opposite sides of said cavity, whereby a human reaching into said aperture means biases said leg members toward each other to release them from said protrusions to release said cover means from said trough.
