AN IMPROVED CISTERN FOR HOUSEHOLD AND DRINKING PURPOSES
Year: 1884

page_text: I, JOSEPH CORNELIUS of No 11 Regent Street in the Parish of East Teignmouth
in the County of Devon, Chemist, do hereby declare the nature of my invention
for "AN IMPROVED CISTERN FOR HOUSEHOLD AND DRINKING PURPOSES" to be as
follows:-
Consists in substituting for the flat bottoms of Cisterns now in use, concave
bottoms or bottoms inclining from all sides of the Cistern to any given point in
the same, and at that point, making a suitable outlet provided with Valves.
Connections, Stop Cocks & for the purpose of runing off rapidly the contents or
a part of the contents of the Cistern, and consequently carry off with the water
all the dirt, grit and other matter that has deposited there (but which is now
allowed to remain month after month and often year after year to the manifest
danger of the public health) because of the difficulty of cleansing the Cisterns of
the present style of construction.

page_text: I, JOSEPH CORNELIUS of 11 Regent Street, Teignmouth, in the County of
Devon, do hereby declare the nature of my said Invention for "AN IMPROVED
CISTERN FOR HOUSEHOLD AND DRINKING PURPOSES;" and in what manner the
same is to be performed to be particularly described and ascertained. in and by
the following statement, reference being had to the accompanying drawings, and to
the letters of reference marked thereon, that is to say :-
The object of this invention is to provide a cistern which shall from its
construction prevent any dirt or other objectionable matter sticking to, or
remaining on the bottom of said cistern.
With this view I form the bottom of my cistern sloping from all sides of the
cistern to a given point, thus forming a well. where dirt & accumulates as deposited
from the water. At the apex of the slopes aforesaid I provido an outlet with
valve or stop-cock attached by which the water, or as much of it as may be
required, is enabled to be run off, carrying with it all the deposit accumulated.
Or, the bottom of my cistern may be of a concave form the outlet aforesaid
being placed at the lowest level possible.
Cisterns constructed in accordance with this my invention may be of any shape
desired, square, oblong, round, oval, or any other shape, and are advantageous both
to the user and to the water companies, a cistern being maintained clean and
wholesome by this my invention with the use of a very little water. By fitting a
solf closing valve at the outlet aforesaid no waste of water can take place by
omitting to shut the water off after flushing, and no accumulation of dirt, now so
common in cisterns as at present constructed, is possible. My cisterns are compact
and do not occupy much space and are moreover inexpensive to manufacture.
And in order that this my invention may be fully understood reference is had to
the accompanying drawings, which shew in section various constructions of my
improved cistern.
a a Figures 1 and 3 being the slopes forming the bottoms of the cisterns with
outlet and valve c for flushing. This valve c may if desired be fitted at the
bottom of outlet pipe b so as to allow the dirt & to accumulate in said pipe b and
then be carried away with the water when c is opened.
Figure 2 shews my cistern with concave bottom d. Valve c and outlet b being
similar to Figures 1 and 2.
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
The construction and arrangement of sloping or concave bottoms and outlet
to cisterns, substantially as and for the purposes hereinbefore set forth and
described.
Dated this Seventeenth day of January 1885.
