Abstract
Abstract A sewage septic tank system including a septic tank for receiving sewage discharge, a liquid junction box operatively connected to receive liquid discharge from the septic tank, at least one, and preferably a plurality of drainage lines opening into the liquid junction box for discharge and draining of liquid therefrom to a drain field and the like, and levelling caps having eccentrically disposed face openings therein, the caps being adjustably mounted on the liquid inlet ends of the drainage lines whereby the openings can be adjusted to provide for varied and different liquid levels in the junction box, and for controllable substantially even distribution of liquid into the drainage lines.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
158 words
A septic tank system comprising a septic tank, a junction box operatively connected to receive liquid from the septic tank, and discharge means operatively connected into said junction box for discharging liquid from the junction box into a septic drain field, said discharge means including an open ended pipe having an end extending into said junction box to receive and discharge liquid therefrom, a cap member mounted on said end being located in said junction box, said cap member including an end closure face having an opening eccentrically offset from the axial center of the pipe and a flange extending from said end clousre face, said flange having an internal dimension for rotatably securing the cap to the open ended pipe, said cap member being rotatably secured to the pipe to variably position said opening with respect to the surface level of a liquid in said junction box, thereby controlling the liquid discharge flow into the drain field.
Claim 2
Dependent Claim
158 words
A septic tank system comprising a septic tank, a junction box operatively connected to receive liquid from the septic tank, and discharge means operatively connected into said junction box for discharging liquid from the junction box into a septic drain field, said discharge means including an open ended pipe having an end extending into said junction box to receive and discharge liquid therefrom, a cap member mounted on said end being located in said junction box, said cap member including an end closure face having an opening eccentrically offset from the axial center of the pipe and a flange extending from said end clousre face, said flange having an internal dimension for rotatably securing the cap to the open ended pipe, said cap member being rotatably secured to the pipe to variably position said opening with respect to the surface level of a liquid in said junction box, thereby controlling the liquid discharge flow into the drain field.
Claim 3
Dependent Claim
29 words
In a septic tank system as claimed in claim 1, wherein said open ended pipe is cylindrical, said cap member has a circular cross-section and a cylindrical shaped flange.
Claim 4
Dependent Claim
155 words
In a septic tank system having a septic tank, a junction box operatively interconnected to the septic tank to receive discharge material from the septic tank, and a plurality of discharge pipes operatively connected to the junction box for discharge of liquid therefrom and distribution into a septic drain field, each of said pipes having an end with an opening extending through a side wall of said junction box to receive liquid therefrom; the improvement comprising a cap rotatably mounted on at least one open end, said cap having a pipe mounting flange and an end closure face, said end closure face having an opening eccentrically offset from the axial center of the pipes and being rotatably secured to the pipe, rotation of said cap serving to variably position the cap opening with respect to the surface level of a liquid in said junction box, thereby controlling the liquid discharge flow into the drain field.
Claim 5
Dependent Claim
155 words
In a septic tank system having a septic tank, a junction box operatively interconnected to the septic tank to receive discharge material from the septic tank, and a plurality of discharge pipes operatively connected to the junction box for discharge of liquid therefrom and distribution into a septic drain field, each of said pipes having an end with an opening extending through a side wall of said junction box to receive liquid therefrom; the improvement comprising a cap rotatably mounted on at least one open end, said cap having a pipe mounting flange and an end closure face, said end closure face having an opening eccentrically offset from the axial center of the pipes and being rotatably secured to the pipe, rotation of said cap serving to variably position the cap opening with respect to the surface level of a liquid in said junction box, thereby controlling the liquid discharge flow into the drain field.
Claim 6
Dependent Claim
81 words
A septic tank system as claimed in claim 1 or 3, wherein a plurality of said open ended pipes extend into said junction box at peripherally spaced positions, each of said open ended pipes having a said cap member rotatably mounted thereon, said cap members being separately individually adjustable to vary the inlet opening of any of the discharge pipes with respect to liquid level in said junction box, enabling even or controlled distribution of discharge liquid into the drain field.
