Improvements in Flushing Chambers and the like, and Fittings
connected therewith.
SAMUEL HENRY ADAMS Hydraulic Engineer Park Avenue Harrogate, do hereby
declare the nature of this invention to be as follows:-
My improvements are specially designed for use where it is desired to use sewage
or other impure waters for automatic syphon, and other Flush Tanks. My intention
being to so clarify this liquid that it shall be less likely to clog or choke the
mechanism employed. For this purpose I use a precipitant as alum or other material
placed, either in the Flush Tank, itself or in a suitable position or space purposely
formed for it in the sewer or drain or channel by which this liquid is led to the
Tank or Chamber, and I so design my Flush Tank that the sediment or thicker
matter separated from the liquid shall fall into a receiver or sump or such a position
that it shall enter the sewer to be flushed when a suitable valve is opened by
preference my flushing apparatus discharging behind this sediment to drive it
forward into the sewer itself.
Another way in which I may do this is by so constructing my tank that the
sewage entering a special compartment or division the liquid from it shall pass
through a suitable filtering wall or medium and thence to the Flush Tank itself in
which the syphon is placed, the heavier matter being allowed to fall into the sewer
when a valve is opened. I may also place my chemical or other filter chamber in
such a position on the supply pipe that the clearer liquid only shall pass to the Flush
Tank, the heavier passing on in the sewer or channel provided.

Improvements in Flushing Chambers and the like, and Fittings

SAMUEL HENRY ADAMS Park Avenue Hydraulic Engineer Harrogate, 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 improvements are especially designed for use where it is desired to use sewage
or impure waters for automatic syphon or other Flush Tanks, my intention being so
to clarify this liquid that it shall be less likely to clog or choke the mechanism

page_text: employed. For this purpose I may use a precipitant as alum or other material
placed either in the Flush Tank itself, or in a suitable position or space purposely
formed for it in the sewer or drain or channel by which this liquid is led to the
tank or chamber and I so design ny Flush Tank that the sediment or thicker matter
separated from the more liquid shall fall into a receiver or sump or such a position
that it shall enter the sewer to be flushed when a suitable valve is opened and by
preference that my flushing apparatus discharging behind this sediment shall drive
it forward into the sewer itself.
Another way in which I may do this is by so constructing my tank that the
sewage entering a special compartment or division the liquid from it shall pass
through a suitable filtering wall or medium and thence to the Flush Tank itself in
which the syphon is placed-the heavier matter being allowed to fall into the sewer
when a suitable valve is opened for the purpose I may also place my chemical or
other filter chamber in such a position that the clearer liquid only shall pass to the
Flush Tank the heavier passing on in the sewer or channel provided. Reference
to the drawings will explain my invention where at Fig 1. is a Flushing Tank
constructed according to my patent-the tank A may be built of brick or any
desired material, and is fitted with a flushing valve automatic or otherwise-in this
instance an automatic syphon B is shewn and this I prefer. The liquid coming in
from pipe C enters receptacle or division D and passing through the filtering medium
at E the heavier matter is deposited on the one side-that is in chamber D, whilst
the filtered or strained liquid passes over to the other into chamber A. The liquid
in this chamber may operate the syphon B or may be allowed to pass off by a valve
to drain or sewer F-the sediment in D is allowed to pass through valve H to the
same drain or sewer. In the event of liquid rising through the gradual choking of
the filtering medium or otherwise it will pass away by pipe G to the sewer itself. In
this instance I open or close my sludge valve H by the spindle & hand wheel.
Fig 2. shews a Flushing Chamber very similar to the last but that provision is
made (by preference in a stone slab laid upon the top of the sludge chamber as a
cover M) in a basket N containing the alumina O or other precipitant it is desired to
use, the sewage flowing over or co:ning in contact with the alumina will be subjected
to chemical reaction the sludge being precipitated to the bottom and the clarified
liquid passing by way of the opening P to the Flushing Chamber A. The sludge in
chamber D is disposed of in the same way as in Fig 1. passing when valve His
opened to the sewer. I may if I prefer precipitate or strain my sewage in small
chambers placed at a little distance from my Flushing Tanks-in this way where
precipitation is resorted to the sewage flowing in the sewer will be much less
offensive no sewer gases will be given off decomposition being stopped by the
precipitant.
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
1st. The use in a Flushing Chamber of a filtering arrangement so constructed that
the impure liquid passing thro this filter on its way to the Flushing Tank proper
shall be strained or filtered in its passage.
2nd. The use in combination of a Flushing Chamber and a filtering arrangement
designed to render impure liquid less impure for the purpose of sewer flushing.
3rd. The use in combination of a Flushing Tank, a screening chamber and a
sludge plug or valve to allow the exit of sludge or deposit to a sewer to be flushed.
4th. The relative positions of the different parts and arrangement and design of
Flushing Tank and screening chamber shown at Fig 1.
5th. The use of a precipitant in combination with a Flushing Tank.
6th. The use of a precipitant, a sludge chamber and a Flush Tank all in combination
for the purposes of sewer Flushing.
7th. The use of a precipitating chamber or a screening Tank in combination with

page_text: altho distinct from and at a distance from the Flushing Tank supplied by the
liquid which shall pass through this chamber.
8th. The general arrangement and design of the parts shewn or their equivalents,
though differing in formation yet substantially the same and for the same
purpose.
