page_text: I, THOMAS ELWORTHY, of No. 101 London Road and No. 24 Springfield Road,
St. Leonards on Sea, in the County of Sussex, Architect do hereby declare the
nature of this invention to be as follows:-
An apparatus for raising and conveying Sewage or other liquids to a distance,
where low levels or tidal influence renders ordinary methods of discharge imprac-
ticable at all times, and to avoid the large expense for working incidental to a
pumping station,
Description, see reference letters on accompanying drawings.
A To represent a small receiver, built in, or attached to an existing Tank, into
which the inflow drains or pipes must empty.
A A division wall of sufficient height to ensure the pipe E being filled when
the weather is dry, or the inflow is small. An ordinary penstock fixed in this
division or wall for connection with the tank, cleansing, or other purposes.
B. A syphon of cast iron, with air tight flange joints, and a check valve in same,
with a second bend C, the height of which is regulated by the rise required, such
double syphon connected with the outfall tank (if any) or forming its own outfall or
discharge by an iron pipe with air tight flanged joints as D. D. The length of
outfall or discharge pipe being regulated by the distance required (in this case
taken as one mile).
E. A pipe connecting the receiver with the outfall, or discharge pipe D. filling
the same by gravity as soon as the sewage or other liquid rises to the level of the
pipe E. This pipe is fitted with an air tight sluice valve (full way) see F.
A similar full way sluice valve is fixed at F* near the outfall which is opened or
closed by a barrel on the spindle, and a continuous steel rope from the syphon end,
attached to the engine or other machinery used for working the air pump, where
the nature of the ground renders such a method practicable, or the situation
favourable thereto.
The sluice valve F⚫ being always closed except when the discharge takes place.
Between F and F the outfall or discharge pipe is provided with air ball valves
at suitable distances, and charcoal deodorisers for the escape of air, while such
outfall or discharge pipe is filling.

page_text: The pipe D. D. being filled the sluice valve at F is closed and the air extracted
from the double syphon by the pipe G. G. connected with an air-pump. At H
and I. are ball valves constructed to allow the air to escape, but closing when the
syphon or pipes are filled with liquid, which will be indicated by a float or pressure
gauge near the engine of air pump.
The sluice valve F being opened by the barrel and steel cord or otherwise, the
whole of the liquid is discharged J. is a well hole for access to bend of syphon
and K a movable cap for cleansing bend of syphon when required.
The apparatus can be easily attached to any existing Tank, and where sewage
from its low level is tide locked, the tank may be emptied several times, regard
being had to size of apparatus and volume to be discharged.

I, THOMAS ELWORTHY, of No. 24 Springfield Road and 101 London Road both.
in St. Leonards on Sea, in the County of Sussex, Architect, do hereby declare the
nature of my invention for RAISING AND CONVEYING SEWAGE TO A DISTANCE,
and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement :-
This Economic Extractor for raising and conveying Sewage to a distance for
discharge, where low levels or tidal influence render ordinary methods of discharge
impracticable at all times, or for irrigation, and to avoid the large expenses for
working incidental to a pumping station, is constructed as follows.
(The reference letters will be found upon the drawings which have been "left
with the Provisional Specification.")
A. To represent a small receiver built in or attached to existing Tank, into
which the inflow drains or pipes must first empty. A a division or wall of
sufficient height to ensure the pipe E being filled when the weather is dry, or the
inflow small; An ordinary penstock fixed in this division or wall for connection
with the tank, cleansing, or other purposes.
B. A syphon of cast iron with air tight flange joints, with a second bend C, the
height of which is regulated by the rise required, such double syphon connected
with the outfall tank (if any) or forming its own discharge by an iron pipe with
flange joints as D. D. the length of outfall or discharge pipe being regulated by the
distance required (in this case the length taken is one mile).
E. A pipe connecting the receiver A with the outfall or dischargo pipe, D, filling
the samo by gravity as soon as the Sewage or other liquid rises to the level of the
pipe E. This pipe is fitted with an air tight sluice valve (full way) at F.
A similar sluice valve is fixed at F* near the outfall, which is opened or closed by
a barrel on the spindle and continuous steel cord from the tank end, attached to
the engine or other machinery used for working the air pump where the nature of
the ground renders such a method practicable, or the situation favourable thereto;
the sluice valve F being always closed except when the discharge takes place ;
Between F and F the outfall or discharge pipe is provided with air ball valves at
suitable distances, (and charcoal deodorisers where necessary) for the escape of air
while the outfall or discharge pipe is filling.
The pipe D. D. being filled, the sluice valve F. is closed, and the air extracted
from the double syphon by the pipes G. G. connected with an air pump.
At H and I are air ball valves, constructed to allow the air to escape but closing
when the syphon or pipes are filled with liquid, which will be indicated by a float
or pressure gauge near the air pump.
The sluice valve F being opened by the barrel and steel cord or otherwise, the
whole of the sewage is at once discharged, and this may be repeated several times
during the time the tide is high; or as often as the receiving tank is filled, regard

page_text: being had to the size of the apparatus, and the volume to be discharged. It may
be affixed to any existing Tank J is a well hole for access to bend of syphon.
K. A cleaning cap to the same.
Having now particularly. described and ascertained the nature of my said
Invention, and in what manner the same is to be performed, I declare that what
I claim is :-
(a.) The combination of a double syphon and outfall or discharge pipe, with
neck or branch into receiver of Tank for automatic filling with Sewage, with two
sluice valves, and escapements or air valves as at H and I, for egress of air from the
same whilst the apparatus is charging..
(b.) The exhaustion of double syphon by pipes, air valves, and air pump when the
discharge pipe is full, and the sluice valves closed, and the discharge, by opening
sluice valve Fa by barrel and steel cord or otherwise.
I do not claim for the air pump or sluice valves F and F (which are the manu-
facture of a firm of Engineers) but only the adaptation of the same in the
"Economic Extractor."
