Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
192 words
In combination, an irrigation system including a selfpropelled vehicle with a water delivery pipe, a water supply pipeline with a plurality of spaced risers, each with a valve therein for supplying water to the water delivery pipe, a capping member with a conical valve therein adapted to seat over each riser to communicate the riser with the delivery pipe, said riser valve comprising a valve disc normally in a closed position, said capping member including a slidable sleeve extending out of the delivery pipe, a sphere with an open bottom secured to the lower end of said sleeve, said conical valve closing off said opening, a gasket around said opening adapted to seal against each of said risers, a striker rod fixed to said conical valve and being substantially longer than the length of said conical valve adapted to strike said riser valve when the sphere is seated on said riser, and pivotal lever means for moving said sleeve and sphere from an uppermost position to a seated position on said riser valve to open each of said valves to cause water to pass from said supply pipe to said delivery pipe.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
163 words
An irrigation device comprising a self-propelled vehicle adapted to move along a fixed pipeline on the ground, having a frame with wheels on the bottom thereof, water discharge means on said vehicle having a substantially horizontal section and a substantially vertical section for discharging water therefrom to irrigate the area, capping means having a sleeve member slidably disposed in said vertical section for detachable connection to riser valves in the pipeline, including a spherical portion in communication with said sleeve member and a valve means in said spherical portion and means for actuating said capping means to connect it in a liquidtight relationship to one of the riser valves, said valve means including a spider member and a striker member carried by spider member, a cone member carried by said striker member including a valve disc adapted to seat against the inner surface of said spherical portion, said valve disc and cone member being fixedly connected to said striker member for movement therewith.
Claim 4
Dependent Claim
163 words
An irrigation device comprising a self-propelled vehicle adapted to move along a fixed pipeline on the ground, having a frame with wheels on the bottom thereof, water discharge means on said vehicle having a substantially horizontal section and a substantially vertical section for discharging water therefrom to irrigate the area, capping means having a sleeve member slidably disposed in said vertical section for detachable connection to riser valves in the pipeline, including a spherical portion in communication with said sleeve member and a valve means in said spherical portion and means for actuating said capping means to connect it in a liquidtight relationship to one of the riser valves, said valve means including a spider member and a striker member carried by spider member, a cone member carried by said striker member including a valve disc adapted to seat against the inner surface of said spherical portion, said valve disc and cone member being fixedly connected to said striker member for movement therewith.
Claim 5
Dependent Claim
