Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
90 words
A system for maintaining an even level of water in a series of troughs each having notched side walls and being spaced apart in the same plane that cOmprises an elongated chamber, an elongated reservoir, a common wall between said chamber and reservoir and defining holes at spaced intervals therealong, the wall of said reservoir opposite said common wall defining a plurality of outlet ports each communicating directly with an end of one of said troughs, said ports generally conforming to the interior cross sectional shape of the trough served.
Claim 2
Independent Claim
90 words
A system for maintaining an even level of water in a series of troughs each having notched side walls and being spaced apart in the same plane that cOmprises an elongated chamber, an elongated reservoir, a common wall between said chamber and reservoir and defining holes at spaced intervals therealong, the wall of said reservoir opposite said common wall defining a plurality of outlet ports each communicating directly with an end of one of said troughs, said ports generally conforming to the interior cross sectional shape of the trough served.
Claim 3
Independent Claim
107 words
A system for maintaining an even level of water in a series of troughs each having notched side walls and being spaced apart in the same plane that comprises an elongated chamber, an elongated reservoir, a common wall dividing said chamber and reservoir and defining holes at spaced intervals therealong, the wall of said reservoir opposite said common wall defining a plurality of outlet ports each communicating directly with an end of one of said troughs, said ports each conforming to the interior cross sectional shape of the trough served but with its upper defining edge in a plane slightly below the bottom of the trough notches.
Claim 4
Independent Claim
107 words
A system for maintaining an even level of water in a series of troughs each having notched side walls and being spaced apart in the same plane that comprises an elongated chamber, an elongated reservoir, a common wall dividing said chamber and reservoir and defining holes at spaced intervals therealong, the wall of said reservoir opposite said common wall defining a plurality of outlet ports each communicating directly with an end of one of said troughs, said ports each conforming to the interior cross sectional shape of the trough served but with its upper defining edge in a plane slightly below the bottom of the trough notches.
Claim 5
Independent Claim
115 words
A system for maintaining an even level of water in a series of troughs each having notched side walls and being spaced apart in the same plane that comprises an elongated chamber, means to feed water to said chamber centrally thereof, an elongated reservoir, a common wall dividing said chamber and reservoir and defining holes at spaced intervals therealong, the wall of said reservoir opposite said common wall defining a plurality of outlet ports each communicating directly with an end of one of said troughs, said ports conforming to the interior cross sectional shape of the trough served but with its upper defining edge in a plane slightly below the bottom of the trough notches.
Claim 6
Independent Claim
115 words
A system for maintaining an even level of water in a series of troughs each having notched side walls and being spaced apart in the same plane that comprises an elongated chamber, means to feed water to said chamber centrally thereof, an elongated reservoir, a common wall dividing said chamber and reservoir and defining holes at spaced intervals therealong, the wall of said reservoir opposite said common wall defining a plurality of outlet ports each communicating directly with an end of one of said troughs, said ports conforming to the interior cross sectional shape of the trough served but with its upper defining edge in a plane slightly below the bottom of the trough notches.
Claim 7
Independent Claim
104 words
A system for maintaining an even level of water in a series of troughs each having notched side walls and being spaced apart in the same plane that comprises an elongated chamber, an elongated reservoir, a common wall dividing said chamber and reservoir and defining holes at spaced intervals therealong, the wall of said reservoir opposite said common wall defining a plurality of outlet ports each communicating directly with an end of one of said troughs, said ports having a cross sectional area slightly less than the cross section of that portion of the trough served lying below the bottom of the trough notches.
Claim 8
Independent Claim
104 words
A system for maintaining an even level of water in a series of troughs each having notched side walls and being spaced apart in the same plane that comprises an elongated chamber, an elongated reservoir, a common wall dividing said chamber and reservoir and defining holes at spaced intervals therealong, the wall of said reservoir opposite said common wall defining a plurality of outlet ports each communicating directly with an end of one of said troughs, said ports having a cross sectional area slightly less than the cross section of that portion of the trough served lying below the bottom of the trough notches.
