PROVISIONAL SPECIFICATION.
Improved Apparatus for Disinfecting Drains and Sewers and
the like.
1 JOSEPH ARNOLD Surveyor and Draftsman 40, Clowance Street, Devonport
in Devonshire do hereby declare the nature of this invention to be as follows:-
My invention relates to combined deodorising, and disinfecting apparatus whereby
sewers, cesspits, and drains, are relieved of gaseous pressure, due to a sudden influx
of water, and the gases in escaping are caused to pass through, or come in contact,
in a more or less divided state, with a disinfecting, and deodorising liquid, and
whereby such liquid is continuously supplied to the sewer, cesspit, or drain itself.
The apparatus essentially of two vessels formed one within the other, and having
a bottom common to both vessels, the wall of the outer vessel projects below
the level of said bottom to a regulated depth to allow of ventilating openings being
made therein, the wall of the inner vessel projects below the level of said bottom
to a regulated depth to allow also of ventilating being made therein, and having
an overflow rim formed inwards at the lower extremity of the said wall. of the
inner vessel, the said overflow rim having a slight seal formed therein, dipping just
to, or below, the surface of a disinfecting liquid supplied to the said overflow rim,
and by which the gases in escaping beneath the said seal are brought in a more
or less divided state, into prolonged, and intimate contact with the liquid in the
said overflow rim. The inner vessel is kept constantly supplied with a chemical
kept in a state of solution, and is caused to overflow into the said rim in regulated
quantity. A regulated quantity of another liquid is supplied from the outer
vessel, the liquids being such that by their chemical combination, gases will be
generated having a powerful disinfecting, and deodorising action on the sewer
gases as they ascend to the overflow rim, and before passing beneath the said
seal, the excess of liquid flows into the cesspit, sewer, or drain, and helps to keep
it sweet.

I JOSEPH ARNOLD of 40 Clowance Street, Devonport in Devonshire, Surveyor
and Draughtsman 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 :-
My invention relates to combined deodorising and disinfecting apparatus, whereby
sewers, cesspits, and drains are relieved of gaseous pressure due to a sudden influx
of water, and the gases in escaping are caused to pass through, or to come in
contact in a more or less divided state with a disinfecting and deodorising liquid,
and whereby such liquid is continuously supplied to the sewer, cess-pit, or drain
itself. Reference is to be had to the accompanying drawing forming part of this
Specification which shews a vertical section of the apparatus.
The apparatus consists essentially of two vessels formed one within the other,
and having a bottom common to both vessels, the wall of the outer vessel projects
D

page_text: below the level of said bottom to a regulated depth to allow of ventilating
openings O, being made therein, the wall of the inner vessel projects below the
level of said bottom to a regulated depth to allow also of ventilating openings V,
being made therein and having an overflow-rim R. R. formed inwards at the lower
extremity of the said. wall of the inner vessel, the said overflow rim having a
slight seal S. S formed therein, dipping just to, or below the surface of a
disinfecting liquid supplied to the said overflow rim, and by which the gases in
escaping beneath the said seal are brought in a more or less divided, state, into
prolonged, and intimate contact with the liquid in the said overflow rim. The
inner vessel A. is kept constantly supplied with a chemical kept in a state of
solution, and is caused to overflow at F. down into the said overflow rim in
regulated quantity. A regulated quantity of another liquid is supplied from the
outer vessel B. B. through a drip-tap T and is carried by an adjustable channel
pipe. P into the said overflow rim R. R the liquids being such that by their
chemical combination gases will be generated having a powerful disinfecting, and
deodorising action on the sewer gases as they ascend to the said overflow rim,
and before passing beneath the said seal S. S. The excess of liquid flows into the
cesspit, sewer, or drain, and helps to keep it sweet. The liquid supplied from
the inner vessel A by the overflow F. is preferably a solution of permanganate
of soda, whilst that supplied from the outer vessel B. B. through the drip-tap T
may be dilute sulphuric acid, and carried by the aforesaid channel pipe P into the
said overflow. rim R. R.
6 Having now particularly described, and ascertained the nature of the said
invention, and in what manner the same is to be performed, I declare that what
I claim is -
The herein described apparatus to be applied to drains, and sewers and the like
consisting of two vessels formed one within the other, with a bottom common to
both vessels, the wall of the outer vessel projects below the said bottom, to allow of
ventilating openings being made therein, the wall of the inner vessel projects below
the said bottom to allow also of ventilating openings being made therein, and
having an overflow rim formed inwards at lower extremity of wall of said inner
vessel, with a seal formed in the said overflow rim slightly immersed in a disinfecting
liquid, and a second liquid supplied through an aperture to the said overflow
rim, as and for the purpose specified.
Dated this 28th day of July 1894
JOSEPH ARNOLD.
