Abstract
Abstract This invention is an improved distribution joint used in conjunction with septic tank absorption field systems. The invention more particularly divides and accurately controls the distribution of septic tank effluent into separate portions of the absorption fields while eliminating the buildup of flow disrupting sediment on the divider by providing a unique flow pattern thereover.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
178 words
An improved flow divider comprising: a septic tank means; an effluent line communicatively connected at one end to said septic tank means; an inlet portion communicatively connected to the end of said effluent line opposite said septic tank means; a distribution portion communicatively connected to a transverse opening in the lower portion of said inlet portion to define (an overhanging) lip from which effluent must drop when passing from said inlet portion to said distribution portion, said transverse opening having a diameter slightly smaller than the interior diameter of said distribution portion; and partition like flow divider means disposed generally beneath said lip and extending across said distribution portion, said divider means including a steeply sloping first edge extending downwardly from a point adjacent said lip and a second edge extending upwardly from the end of said first edge opposite said lip at an angle greater than ninety degrees, with said first and second edges being of the knife edge type, whereby the buildup of particulate and other solids on or adjacent the flow divider can be prevented.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
19 words
The improved flow divider of claim 1 wherein said partition like flow divider is constructed from relatively thin material.
Claim 4
Dependent Claim
17 words
The improved flow divider of claim 1 wherein a clean-out opening is provided in said inlet portion.
Claim 5
Dependent Claim
16 words
The improved flow divider of claim 3 wherein a cover is provided for said clean-out opening.
Claim 6
Dependent Claim
26 words
