Abstract
Abstract A drainage reservoir for an underground watering system consisting of a sump substantially frusto conical in form having a plurality of apertures therein, said apertures comprising drainage valves which include valve members in connection with each of said apertures which yield to the pressure of water within said reservoir to open said apertures for pssage of said water through said apertures and which yield to subsurface water pressures to close said apertures against the entrance of subsurface waters into sad reservoir.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
91 words
A drainage reservoir for an underground sprinkling system having in combination: an enclosed housing having a drain line from said system running thereinto, apertures through the walls of said housing spaced thereabout, and a valve structure mounted in operative association with each of said apertures yielding to the pressure of drainage water from within said housing to permit the passage of said water out of said housing and yielding to the oressure of subsurface waters about said housing to seal said apertures against the entrance of said waters into said housing.
Claim 2
Dependent Claim
91 words
A drainage reservoir for an underground sprinkling system having in combination: an enclosed housing having a drain line from said system running thereinto, apertures through the walls of said housing spaced thereabout, and a valve structure mounted in operative association with each of said apertures yielding to the pressure of drainage water from within said housing to permit the passage of said water out of said housing and yielding to the oressure of subsurface waters about said housing to seal said apertures against the entrance of said waters into said housing.
Claim 3
Dependent Claim
113 words
The structure set forth in claim 1, wherein said apertures each comprise a relatively large opening and a relatively small opening thereabove, said valve structure comprises a body portion in the form of a flap overlying said relatively large opening, said body portion has a neck portion of small transverse dimension adapted to be disposed through said smaller opening to hold said flap portion in operating position overlying said larger opening, said neck portion having an enlarged terminal portion at the inner side of said housing adapted to be disposed through said smaller opening to hold said valve member in operating position, and said body portion is swingably carried by said neck portion.
Claim 4
Dependent Claim
130 words
The structure set forth in claim 1, wherein said valve structure comprises a base portion which overlies the outer side of an aperture and a head portion which overlies the inner side of said aperture; a neck portion is disposed through said aperture connecting said base portion and said head portion and having sufficient length for some movement of said valve structure axially of said aperture, said neck portion having a plurality of radial ribs extending outwardly therefrom within said aperture, and said head portion having a plurality of underlying open bottom radial grooves whereby water will drain out of said reservoir through said radial grooves and through said apertures, the pressure of said water moving said valve structure outwardly of said aperture sufficiently for drainage outwardly of said housing.
Claim 5
Dependent Claim
61 words
The structure set forth in claim 1, wherein said valve structure comprises one portion overlying the outer side of an aperture and a second portion overlying the inner side of said aperture, means connecting said portions and providing for movement thereof axially of said aperture, and said second portion and said connecting means permitting drainage of water outwardly of said housing.
