Abstract
Abstract A well service structure for remote positioning in respect to residences served and comprising a top pipe section connected to a wall casing that extends vertically downward. The top pipe is itself encased partially by a spherical resin tank cast in hemispheres and joined to the top pipe and to each other. The interior of the top pipe is provided with a taper portion, the lower portion of the taper is shouldered and is slightly smaller in diameter than the upper taper portion and the top pipe is perforated intermediate the limits of the tapered portion. A flow director supporting well pipe and pump is provided which is connected to the upper section of well pipe so that water from the well enters the distributor axially and is diffused radially through the perforations in the top pipe extension and into the spherical tank. The top plate closure of the flow director includes a taper faced ring seal and the lower plate closure on the flow director includes a similar but smaller taper faced seal and both are seated on the tapered portion provided in the top pipe. In addition, a flange portion of the taper faced seal rests on an internal shoulder provided in the top pipe. The spherical tank is provided with a resilient membrane in the upper portion which separates the tank into two parts, the part below the membrane being vented to atmosphere via a bent tube and the lower part is provided with a delivery nipple connectable to a remote use facility. The tank is preferably buried and in some situations, may be housed above ground and preferably remote from the residence or dwelling served. The upper portion of the top pipe extends above the ground and is preferably closed by a protective clousre but may be selectively opened to permit axial removal of flow director, well pipe, pump, strainers, foot valves, and the like.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
67 words
In a well service structure wherein a flow distributor is located within a top pipe extension of well casing the combination comprising: a spherical tank secured to the top pipe and around radial openings through the top pipe; diaphragm means for resiliently confining a compressible gas media above liquid in said tank; and a connecting nipple through said tank whereby liquid may be drawn from said tank.
Claim 2
Dependent Claim
67 words
In a well service structure wherein a flow distributor is located within a top pipe extension of well casing the combination comprising: a spherical tank secured to the top pipe and around radial openings through the top pipe; diaphragm means for resiliently confining a compressible gas media above liquid in said tank; and a connecting nipple through said tank whereby liquid may be drawn from said tank.
Claim 3
Dependent Claim
31 words
In the combination as expressed in claim 1 wherein a resilient nonporous diaphragm separates said liquid phase from said gas phase in a relationship of about one-third gas to two-thirds liquid.
Claim 4
Dependent Claim
21 words
The combination as expressed in claim 1 and including a selectively usable vent tube from said liquid side of said diaphragm.
Claim 5
Dependent Claim
167 words
A well service structure comprising: a top pipe connectable to well casing and extending thereabove which inclUdes a tapered portion providing seal seats, the upper part of said tapered portion being of larger size than the lower part of said tapered portion and radial openings through said top pipe intermediate the upper and lower parts of said tapered portion; a thrust shoulder adjacent and below the said lower part of said tapered portion; a flow director having a pair of tapered faced resin seals insertable axially through said top pipe and closing on said tapered portion and said shoulder above and below said openings and said flow direction connectable to well pipe extending axially below said top pipe; a spherical tank surrounding said top pipe and secured thereto and said radial openings communicating the interior of said top pipe isolated by said flow director to the interior of said tank; and a resilient diaphragm separating said tank into an upper gas chamber and a lower water chamber.
Claim 6
Dependent Claim
167 words
A well service structure comprising: a top pipe connectable to well casing and extending thereabove which inclUdes a tapered portion providing seal seats, the upper part of said tapered portion being of larger size than the lower part of said tapered portion and radial openings through said top pipe intermediate the upper and lower parts of said tapered portion; a thrust shoulder adjacent and below the said lower part of said tapered portion; a flow director having a pair of tapered faced resin seals insertable axially through said top pipe and closing on said tapered portion and said shoulder above and below said openings and said flow direction connectable to well pipe extending axially below said top pipe; a spherical tank surrounding said top pipe and secured thereto and said radial openings communicating the interior of said top pipe isolated by said flow director to the interior of said tank; and a resilient diaphragm separating said tank into an upper gas chamber and a lower water chamber.
Claim 7
Dependent Claim
28 words
The combination as set out in claim 4 wherein said resilient diaphragm is sealed centrally to said top pipe and sealed peripherally to the interior of said tank.
Claim 8
Dependent Claim
201 words
In a well service structure comprising a top pipe extension of well casing having a tapered portion and radial openings therethrough intermediate the ends of said tapered portion seats in spaced apart axial relation above and below said openings, said tapered portion having the upper seat larger than the lower seat, and a spherical resin tank having a phase separating diaphragm surrounding and sealed to the top pipe, the flow director comprising: an upper plate closure disc; a lower plate closure disc in spaced apart parallel relation to said upper plate, said lower plate having a smaller diameter than said first plate; spacers maintaining a spaced parallel interval between and secured to said plates, one of said spacers being hollow and through said upper and lower plates; a threaded nipple axially through the lower of said plates; a threaded coupling secured to the upper of said plates and extending axially thereabove; and a pair of taper faced resin seals molded to the periphery of said upper and lower plates, whereby said seals seat on a mating taper in said top pipe and against a thrust shoulder when said flow distributor is axially secured to well pipe and lowered into well casing.
Claim 9
Dependent Claim
201 words
In a well service structure comprising a top pipe extension of well casing having a tapered portion and radial openings therethrough intermediate the ends of said tapered portion seats in spaced apart axial relation above and below said openings, said tapered portion having the upper seat larger than the lower seat, and a spherical resin tank having a phase separating diaphragm surrounding and sealed to the top pipe, the flow director comprising: an upper plate closure disc; a lower plate closure disc in spaced apart parallel relation to said upper plate, said lower plate having a smaller diameter than said first plate; spacers maintaining a spaced parallel interval between and secured to said plates, one of said spacers being hollow and through said upper and lower plates; a threaded nipple axially through the lower of said plates; a threaded coupling secured to the upper of said plates and extending axially thereabove; and a pair of taper faced resin seals molded to the periphery of said upper and lower plates, whereby said seals seat on a mating taper in said top pipe and against a thrust shoulder when said flow distributor is axially secured to well pipe and lowered into well casing.
Claim 10
Dependent Claim
154 words
A spherical tank for well service structures which include a flow distributor and a top pipe extension above well casing, comprising: a pair of hemispheric shells formed from reinforced resin material, said shells closing on a top pipe and sealed thereto and peripherally connected to each other forming a hollow sphere axially penetrated by said top pipe; a resilient diaphragm secured to said top pipe and secured internally to at least one of said hemispheric elements whereby two chambers are formed in said tank by said diaphragm, the upper of said chambers containing gas and the lower of said chambers in communication through said top pipe with liquid; a delivery nipple through said tank communicating with the lower of said chambers; and a tube through said diaphragm selectively openable and closable to atmosphere whereby gases collecting on said liquid phase side of said membrane may be selectively vented and used for gaging and controlling.
