Abstract
Abstract This invention relates to sewage systems, FIG. 3, it particular to a vented leaching channel for use in such systems. A plurality of vented leaching channels are arranged in a corresponding plurality of trenches in the leaching field of a sewage system so as to control the flow of sewage and to form a volume underground for storage output during aerobic action thereon. Each leaching channel comprises a series of leaching channel units arranged end-to-end, the first unit having an end cover adapted to receive the sewage and the last unit having a vent. Except for the end cover and vent, the units are identical for ease of manufacture and installation, and each includes a barn or shedlike structure having sheltered apertures in its walls adapted to permit outward flow of sewage while preventing inward flow of dirt and other undesirable material. Special access apertures are also provided in all the units.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
100 words
A vented leaching channel for use in sewage systems, comprising a series of channel units, each unit comprising a barn or shedlike structure having sheltered apertures in its walls adapted to permit outward flow of sewage while preventing inward flow of dirt and other undesirable material, wherein said apertures are arranged in a plurality of vertically spaced horizontal rows and wherein the shelter for said apertures comprises a corresponding plurality of outer lips extending the length of the unit, the width of any lip being less than that of all higher lips and greater than that of all lower lips.
Claim 2
Dependent Claim
100 words
A vented leaching channel for use in sewage systems, comprising a series of channel units, each unit comprising a barn or shedlike structure having sheltered apertures in its walls adapted to permit outward flow of sewage while preventing inward flow of dirt and other undesirable material, wherein said apertures are arranged in a plurality of vertically spaced horizontal rows and wherein the shelter for said apertures comprises a corresponding plurality of outer lips extending the length of the unit, the width of any lip being less than that of all higher lips and greater than that of all lower lips.
Claim 3
Dependent Claim
162 words
A leaching field comprising a plurality of trenches, a distribution box, a series of channel units in each trench, each channel unit comprising a pair of apertured walls and an unapertured ceiling connecting said walls and sheltering the volume between said walls, connectors between the ceilings of adjacent channel units, said connectors sheltering the volume below them, an end wall at that end of each series which is the more remote from said distribution box, an inlet wall at the other end of each series, said inlet wall including an aperture adapted to receive effluent from the distribution box, and a vent near said end wall, wherein the apertures in said apertured walls are arranged in a plurality of horizontal rows and wherein the shelter for said apertures comprises a corresponding plurality of outer lips extending the length of the unit, the width of any lip being less than that of all higher lips and greater than that of all lower lips.
Claim 4
Dependent Claim
162 words
A leaching field comprising a plurality of trenches, a distribution box, a series of channel units in each trench, each channel unit comprising a pair of apertured walls and an unapertured ceiling connecting said walls and sheltering the volume between said walls, connectors between the ceilings of adjacent channel units, said connectors sheltering the volume below them, an end wall at that end of each series which is the more remote from said distribution box, an inlet wall at the other end of each series, said inlet wall including an aperture adapted to receive effluent from the distribution box, and a vent near said end wall, wherein the apertures in said apertured walls are arranged in a plurality of horizontal rows and wherein the shelter for said apertures comprises a corresponding plurality of outer lips extending the length of the unit, the width of any lip being less than that of all higher lips and greater than that of all lower lips.
Claim 5
Dependent Claim
86 words
A vented leaching channel for use in sewage systems, comprising a series of channel units, each unit comprising a barn or shedlike structure having apertures in its walls arranged in a plurality of vertically spaced horizontal rows and adapted to permit outward flow of sewage while preventing inward flow of dirt and other undesirable material, said apertures extending outward through the thickness of said walls at a downwardly sloping angle such that a horizontal line cannot pass through the aperture in the thickness of said walls.
Claim 6
Dependent Claim
86 words
A vented leaching channel for use in sewage systems, comprising a series of channel units, each unit comprising a barn or shedlike structure having apertures in its walls arranged in a plurality of vertically spaced horizontal rows and adapted to permit outward flow of sewage while preventing inward flow of dirt and other undesirable material, said apertures extending outward through the thickness of said walls at a downwardly sloping angle such that a horizontal line cannot pass through the aperture in the thickness of said walls.
