A valve for controlling the flow of water from an irrigation pipe, the combination of a circular grommet of resilient material, said grommet having an annular recess in the circular outer surface thereof, said recess receiving the lip of a hole formed in a flattened part of the wall of an irrigation pipe, a hollow cylindrical valve member having an end wall forming the bottom thereof, said valve member having a plurality of holes in the cylindrical wall thereof adjacent to said end wall, said grommet having a circular inner surface in frictional engagement with the circular outer surface of said valve member so that said valve member is supported on said flattened wall of said pipe, said valve member being adjustable with respect to said grommet, said grommet closing said holes adjacent to said end wall when said valve member is adjusted so that said end wall is positioned in close proximity to the bottom of said grommet, said valve member having a top flange around the open top thereof, said valve member being adapted to be opened by a workman hitting said top flange and moving said valve member inward in said grommet so that said holes are opened into the inside of the irrigation pipe to allow water to flow out of said pipe through said holes.

A valve for controlling the flow of water from an irrigation pipe, the combination of a circular grommet of resilient material, said grommet having an annular recess in the circular outer surface thereof, said recess receiving the lip of a hole formed in a flattened part of the wall of an irrigation pipe, a hollow cylindrical valve member having an end wall forming the bottom thereof, said valve member having a plurality of holes in the cylindrical wall thereof adjacent to said end wall, said grommet having a circular inner surface in frictional engagement with the circular outer surface of said valve member so that said valve member is supported on said flattened wall of said pipe, said valve member being adjustable with respect to said grommet, said grommet closing said holes adjacent to said end wall when said valve member is adjusted so that said end wall is positioned in close proximity to the bottom of said grommet, said valve member having a top flange around the open top thereof, said valve member being adapted to be opened by a workman hitting said top flange and moving said valve member inward in said grommet so that said holes are opened into the inside of the irrigation pipe to allow water to flow out of said pipe through said holes.
Claim 3
Dependent Claim
90 words
A valve for controlling the flow of water from an irrigation pipe, the combination as set forth in claim 1, further characterized in that said substantially round outer surface of said valve member is provided with a rounded helical thread engaging a corresponding helical groove in the inner surface of said grommet, said grommet being of yieldable Material so that said valve member may be pressed inward by applying axial pressure thereto without turning said valve member and said valve member may be moved into either position by turning it.
Claim 4
Dependent Claim
49 words
A valve for controlling the flow of water from an irrigation pipe, the combination as set forth in claim 1, further characterized in that the flattened part of the wall of the irrigation pipe is recessed into the pipe to protect the valve member during handling of the pipe.
