Claims Analysis

Total Claims: 2
Claim 1
Independent Claim 292 words
An irrigating device for plants and the like comprising: a. A flexible fluid disseminator, said disseminator having an elongated flexible perforated tube, the major portion of which is adapted to be placed beneath the surface of the ground adjacent the root system of plants for irrigating the same, said tube having means extending upward above the ground for connecting the same to a liquid supply; b. a plurality of separate liquid distributing elements spaced along said tube; c. each of the liquid distributing elements comprising a moisture retaining material of loosely assembled fibers surrounding said tube and a liquid pervious outer retainer surrounding the moisture retaining material for holding the same in place about the tube; d. ties at each end of each liquid pervious outer retainer for selectively positioning the location of the same; e. a liquid receptacle positioned in the liquid inlet end of the tube, said liquid receptacle having a perforated rotatable funnel like element for receiving the liquid; f. a liquid tight outer container for receiving said liquid from the funnel like element; g. a valve positioned adjacent the bottom of the outer container; h. A handle for rotating said funnel like element, the funnel like element having a flat surface adjacent its apex and perpendicular to the rotatable axis of the funnel like element; i. a stationary portion of said valve carried by the said outer container comprising a flat surface positioned adjacent the flat surface of the funnel like element having a plurality of openings therethrough; j. means carried by the rotating surface for rotating and closing said openings through the stationary surface of the said valve when the funnel like element is rotated by said handle to regulate the flow of liquid into the tube.
