COMPLETE SPECIFICATION (AMENDED).
Improvements in the Disposal of Sewage, and Apparatus connected
therewith.
I JOSEPH NORRIS of Sunningdale in the Parish of Egham in the County of
Surrey Builder and Contractor do hereby declare the nature of this invention and
in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement:-
The nature object of the this invention is a new method for the disposal of sewage
without the ordinary cesspool and for the prevention of the accumulation of sewer
gas, in the soil pipe. The new method deals with According to this invention the soil
from waterclosets &c. is dealt with in the following manner.
A chamber called the fresh air inlet chamber is constructed in the ground as
shewn by sections A. B and C. D in the plan drawing accompanying this
Specification. The sides and ends of the chamber are lined with white glazed
bricks or glazed earthenware. The slopes of the bottom marked E and F on the
plan are of concrete and are lined with white glazed tiles and at the bottom is en
enamel-overflow-pipe a central gutter marked G on-plan leading to an enamel overflow
pipe to carry off the liquid portion of the soil. The chamber is covered in by a
hinged iron grating which is marked A. B. C. D. on (see the plan view). The soil
drain, marked H, on plan from the watereloset house enters this chamber about
1 foot from the bottom. Underneath the orifice outlet of the soil drain is placed
a strainer marked I on plan of the shape and size shewn in the accompanying plan
the sides and ends of which are made of galvanized iron wires about a quarter of
an inch apart the top of the strainer being open. The bottom of the strainer is
made of galvanized sheet iron punctured all over with holes of about a quater of
an inch in diameter and turned up about two inches all round.
There is a handle marked J on plan to the strainer so that it may be taken ont
and replaced daily. Two iron rods guides marked K and Lon-plan rise from the
bottom of the chamber to the sides as shewn in the cross section A. B. of the plan to
keep ensure the strainer in taking and keeping its proper position in the chamber.
When the soil enters the strainer the solid portion is retained by the strainer
but the liquid portion passes into the chamber gutter G and is carried off by the
overflow pipe before mentioned. The strainer should be lifted out by means of
the handle and emptied daily and the contents dug into the earth, the strainer is
being then replaced. A current of fresh air induced by a ventilating shaft passes
through the iron grating of the inlet chamber and through the soil drain // which
is connected with an ordinary the ventilating shaft as shewn in the section
drawing.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is
