Abstract
Abstract An adjustable valve for use on irrigation pipes to control or to shut off the water flow. This device is provided with a flexible grommet that is inserted into a hole in the irrigation pipe and supports the valve member on the pipe. The grommet is provided with a tapered inwardly projecting lip that extends a short distance into the irrigation pipe and frictionally engages the body of the valve member. This grommet lip is stretched slightly by a tapered flange that is provided on the valve member when the valve member is inserted into the grommet. This lip contracts to grip the body of the valve member after the tapered flange of the valve member is pressed through the grommet. The valve member may be adjusted in the grommet to control the water flow out of the pipe through openings in the body of the valve member. When it is desired to close the valve, the valve member is moved outward until the grommet lip and tapered flange engage each other. These parts also limit the outward withdrawal of the valve member from the grommet.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
222 words
A valve for controlling the flow of water from an irrigation pipe, the combination of a grommet of resilient material, said grommet having a recess in the outer surface thereof, said recess receiving the edge of an opening formed in part of the wall of an irrigation pipe, a hollow valve member supported by said grommet, said valve member having an end wall forming the bottom thereof, said valve member also having a tapered flange extending beyond the sides thereof and surrounding said bottom, the body of said valve member having a plurality of holes in the sides thereof, said grommet having a hole therethrough and the diameter of said hole at the top of said grommet being large enough to receive said tapered flange, said grommet also having an inwardly tapered lip at the bottom thereof for frictionally engaging the sides of the body of said valve member, said valve member having a top flange around the open top thereof, said valve member being adjustable with respect to said grommet so that said holes of said valve member open into the inside of the irrigation pipe when said top flange is adjacent to said grommet, said valve member being closed with respect to said irrigation pipe when said end wall is positioned in close proximity to the bottom of said grommet.
Claim 2
Dependent Claim
222 words
A valve for controlling the flow of water from an irrigation pipe, the combination of a grommet of resilient material, said grommet having a recess in the outer surface thereof, said recess receiving the edge of an opening formed in part of the wall of an irrigation pipe, a hollow valve member supported by said grommet, said valve member having an end wall forming the bottom thereof, said valve member also having a tapered flange extending beyond the sides thereof and surrounding said bottom, the body of said valve member having a plurality of holes in the sides thereof, said grommet having a hole therethrough and the diameter of said hole at the top of said grommet being large enough to receive said tapered flange, said grommet also having an inwardly tapered lip at the bottom thereof for frictionally engaging the sides of the body of said valve member, said valve member having a top flange around the open top thereof, said valve member being adjustable with respect to said grommet so that said holes of said valve member open into the inside of the irrigation pipe when said top flange is adjacent to said grommet, said valve member being closed with respect to said irrigation pipe when said end wall is positioned in close proximity to the bottom of said grommet.
Claim 3
Dependent Claim
113 words
A valve for controlling the flow of water as set forth in claim 1, further characterized in that the slope of said tapered flange is substantially parallel to the inclined inner surface of said tapered lip when said tapered flange first engages said tapered lip during the assembly of said valve member with said grommet, and said tapered lip is expanded by said tapered flange when said valve member is fully inserted into said grommet, thereafter said tapered lip engages the body of said valve member up to the shoulder of said tapered flange during adjustment of said valve member so that said valve member can not be accidentally removed from said grommet.
