COMPLETE SPECIFICATION.
An Apparatus for Purifying, Disinfecting, and Deodorizing the
Contents of Sewers, Drains, Cesspools, and other analogous
Places Requiring to be Disinfected.
I, FREDERICK ALEXANDER BLACK of 16 Union Street Inverness North
Britain, Solicitor, 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 an apparatus for purifying disinfecting and deodorizing
the contents of sewers drains cesspools and other analogous places requiring to be
disinfected.
In order that my invention may be properly understood and readily carried into
effect I have hereunto appended one sheet of drawing representing a section of
the apparatus.
The apparatus consists of an upper vessel A. and lower vessel B, the latter being
provided with an outlet pipe or dropping pipe C. Inside the apparatus there are
two tubes a and b. a is an air pipe extending from near the top of the vessel A
where it is open to the atmosphere through the bottom (being soldered round
about) and terminating in the lower compartment B, slightly above the level of
the drop pipe C. 'The screw tube b, extends from about the top of the upper
compartment through the bottom (being also soldered round about) to the bottom
of the lower compartment. It is open at the top but closed at the bottom. It has
three slits in its side b¹ b³ ³, one 6' just above the bottom of the upper compart-
ment, a second b³ just above the level of the drop pipe, and the third * just above
the bottom of the lower compartment.
The action of the apparatus is as follows:-The upper compartment is filled
with disinfecting liquid and the stopper screwed in so as to be air-tight. Air
enters and liquid escapes only through the tube b. Air enters the lower compart-
ment freely through the tube a, but until the liquid in the lower compartment has
by dropping sunk to the level of the centre slit in the tube b no air can get into
the upper compartment. Whenever a bubble of air gets into the upper
compartment a few drops of liquid escape from it and again the air supply to the
upper compartment is cut off until the liquid has again sunk in the outer box.
In order to regulate the rate of flow a bent pipe is coupled on to the outlet
pipe which can be turned round to increase or diminish the amount of discharge.
If it is found objectionable to have a continuous dropping and it is desired to
discharge a larger quantity at longer intervals I provide a tip-over bucket D
which can be used by hanging on the outlet pipe C. When this bucket fills to a
certain height it tips over and discharges its contents and immediately rights
itself.
A stop-cock c is provided to stop the flow altogether when required.
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 :-
The apparatus for supplying purifying, disinfecting and deodorizing liquids to
sewers, drains, cesspools, and the like, substantially as described and illustrated.
