Abstract
Abstract This invention is in regard to septic tank drainage conduit structures, including an open-sided conduit structure for installation in clay type soil conditions and a U-shaped conduit structure for use in loose or sandy soil conditions. Each conduit structure is constructed of an integral material and of a large size to achieve maximum absorption of waste septic fluid into the surrounding soil area. Each conduit structure is supported on leg members with a completely open bottom area between the leg members to achieve maximum waste water absorption downwardly from each conduit structure.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
175 words
A conduit structure to be placed in a trench adapted to be connected to a conventional septic tank structure to convey waste water therefrom for absorption into the soil area surrounding said conduit structure, comprising; (a) said conduit structure having a main body assembly with a top wall member mounted on spaced support leg members; (b) said support leg members having a drainage hole therein to permit waste water flow therethrough; (c) said main body assembly having an open area between said support leg members and downwardly of a lower surface of said top wall member to permit free flow of waste water downwardly therefrom into the soil area; and (d) said support legs extended downwardly and perpendicular to said top wall member and transverse to the longitudinal axis of said top wall member, whereby the waste water can flow freely laterally of said top wall member starting at a position directly below a lower surface of said top wall member into the adjcent soil area which is of a generally solid clay type composition.
Claim 2
Dependent Claim
175 words
A conduit structure to be placed in a trench adapted to be connected to a conventional septic tank structure to convey waste water therefrom for absorption into the soil area surrounding said conduit structure, comprising; (a) said conduit structure having a main body assembly with a top wall member mounted on spaced support leg members; (b) said support leg members having a drainage hole therein to permit waste water flow therethrough; (c) said main body assembly having an open area between said support leg members and downwardly of a lower surface of said top wall member to permit free flow of waste water downwardly therefrom into the soil area; and (d) said support legs extended downwardly and perpendicular to said top wall member and transverse to the longitudinal axis of said top wall member, whereby the waste water can flow freely laterally of said top wall member starting at a position directly below a lower surface of said top wall member into the adjcent soil area which is of a generally solid clay type composition.
Claim 3
Dependent Claim
193 words
A conduit structure to be placed in a trench adapted to be connected to a conventional septic tank structure to convey waste water therefrom for absorption into the soil area surrounding said conduit structure, comprising; (a) said conduit structure having a main body assembly with a top wall member mounted on spaced support leg members; (b) said support leg members having a drainage hole therein to permit waste water flow therethrough; (c) said main body assembly having an open area between said support leg members to permit free flow of waste water downwardly therefrom into the soil area; (d) said support legs extended downwardly and perpendicular to said top wall member and transverse to the longitudinal axis of said top wall member, whereby the waste water can flow freely laterally of said top wall member starting at a position below a lower surface of said top wall member into the adjacent soil area which is of a generally solid clay type composition; and (e) said support leg members have downwardly, inwardly inclined end walls to permit waste water flow longitudinally of said conduit structure about said end walls and through said drainage hole.
Claim 4
Dependent Claim
193 words
A conduit structure to be placed in a trench adapted to be connected to a conventional septic tank structure to convey waste water therefrom for absorption into the soil area surrounding said conduit structure, comprising; (a) said conduit structure having a main body assembly with a top wall member mounted on spaced support leg members; (b) said support leg members having a drainage hole therein to permit waste water flow therethrough; (c) said main body assembly having an open area between said support leg members to permit free flow of waste water downwardly therefrom into the soil area; (d) said support legs extended downwardly and perpendicular to said top wall member and transverse to the longitudinal axis of said top wall member, whereby the waste water can flow freely laterally of said top wall member starting at a position below a lower surface of said top wall member into the adjacent soil area which is of a generally solid clay type composition; and (e) said support leg members have downwardly, inwardly inclined end walls to permit waste water flow longitudinally of said conduit structure about said end walls and through said drainage hole.
Claim 5
Dependent Claim
74 words
A conduit structure as described in claim 2, wherein: (a) said top wall member having a septic inlet piping assembly connected thereto to convey septic tank waste water to an interior and centrally of said main body assembly; and (b) said conduit structure having spaced transfer members anchored to said top wall member, whereby said transfer members are to be grasped to transfer and move the entire said conduit structure to the proper location.
