Improvements in Appliances connected with Waterworks and
Reservoirs.
I, CHARLES THOMPSON, of 2 St. James's Place, Otley Road, Baildon in the
County of York; Mill Furnisher do hereby declare the nature of this invention to
be as follows:
"
This invention relates to improved appliances for withdrawing the surplus, or
"overflow water from reservoirs, and other water storage works in such a manner
that water which has longest been in the reservoir, and is consequently more likely
to be impure; and water in which there is more or less sediment is first drawn off,
when there is a supply greater than the demand and the water being drawn from
the bottom of the reservoir in lieu of the top as heretofore, tends to keep the
bottom of the said reservoir clean and free from sediment.
According to this my said invention I employ outlet or overflow pipes, or a
conduit built somewhat similar to an inverted U-n. One end of the pipe, or
conduit is bent along the bottom of the reservoir and is open for the passage of
water, and the other end of the conduit is connected with the overflow pipe. At
or near the top or apex of the conduit the latter is open and formed with one of
the edges overlapping the other.
The action is as follows:-Water passing into the inlet end of the overflow
conduit will necessarily rise up the pipe or conduit to the same level as the
surrounding water, and when this rises above the apex of the the water will
commence flowing down the other side and to the outlet and so continue until the
level of the water falls; the opening at the top of the conduit preventing the
acting as a syphon and also allowing more water to flow down the and to the
outlet in the event of water coming into the reservoir in greater quantity than can
flow through the inlet end of the overflow conduit. The pipe supplying the "main"
is placed in the usual position.

Improvements in Appliances connected with Waterworks and
Reservoirs.
I CHARLES THOMPSON of 2 St. James's Place, Otley Road, Baildon in the
County of York Mill Furnisher, 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:-
This invention relates to improved appliances for withdrawing the surplus, or
"overflow" water from reservoirs, and other water storage works in such a manner
that water which has longest been in the reservoir, and is consequently more likely
to be impure; and water in which there is more or less sediment is first drawn off,
when there is a supply greater than the demand, and the water being drawn from
the bottom of the reservoir in lieu of the top as heretofore tends to keep the
bottom of the said reservoir clean and free from sediment.
According to this my said invention I employ outlet or overflow pipes, or a
conduit built somewhat similar to an inverted U-n. One end of the pipe, or

conduit is bent along the bottom of the reservoir and is open for the passage of
water, and the other end of the
or near the top or apex of the
the edges overlapping the other.
conduit is connected with the overflow pipe. At
conduit the latter is open and formed with one of
Such being the nature and object of my said invention the following is a
complete description of same reference being made to the accompanying drawings
in which
Fig. 1 is a plan view of a reservoir having my improved appliances for with-
drawing the surplus water therefrom applied thereto.
Fig. 2 is a sectional side elevation of a part of Fig. 1.
Fig. 3 is a sectional side elevation shewing a modified form of my improved
appliance.
According to this my said invention I employ outlet or overflow pipes 1. 1.
preferably branching to different points at the bottom of the reservoir 2 such pipes,
or branches 1. 1. are open at the ends 3. 3. and the outlet. or overflow end 4 of the
pipes or conduit is curved or bent upwards to, and over, or through the retaining
bank or wall 5 of the reservoir 2, the outlet 6 being at a point as high as that
at which the surplus water in the reservoir begins to overflow, and escape by the
"bye-wash" 7.

In lieu of discharging the surplus water at a point as high as the "overflow
'mark of the reservoir 2 I in some cases prefer to discharge it at or near the
bottoin, in which event the pipe or conduit 1 is bent or built somewhat similar to
an inverted U-n (see Fig. 3). One end of the pipe or conduit 1 is bent along
the bottom of the reservoir preferably as shewn by Fig. 1 and is open for the
passage of water, and the other end-4 of the conduit is connected by pipes
passing through the lower part of the retaining bank or wall 5 of the reservoir 2
to the "bye-wash" 7. At or near the top or apex 8 of the conduit 1 the latter is
open and formed with one of its edges 9 overlapping the other, the branch 1" of the
conduit being about twice the diameter of the branch 1 for the purpose of carrying
"off surplus water which passes up the branch 1 and also through the opening '10 at
'the top or apex 8 when the water rises above such opening.
From the pipes 1 at the bottom of the reservoir 2 a branch 11 extends which
may be connected with the "main" 12' or the "bye-wash" 7 and in this branch
pipe 11 is a valve 12" operated by spindle and handle 13. so that by opening the
valve the water can be drawn from the bottom of the reservoir 2. either for the
purpose of flushing and cleaning the pipes, or for emptying the reservoir.
When the water in the reservoir 2 rises it necessarily rises to the same height in
the pipés or conduit '1 and when' the water has risen' above the point 14 it escapes
by way of the outlet 6 and " bye-wash" 7 (see Figs. 1 and 2) the water which
passes through the outlet 6 being drawn from the bottom of the reservoir 2, and
bye-wash 7 in
that which cannot escape by the pipes 11. 1. is carried over the "
the ordinary way. In Fig. 3 the action is similar to the above described but the
water passes down the branch 1" and escapes from the outlet-6 at the bottom of the
retaining bank or wall 5, the opening 10 preventing the conduit 1 acting as a
syphon, and also allowing, water to pass down the branch 1 in the event of its
collecting or coming into the reservoir in greater quantity than can flow through
the branch 1.
It will be seen that water will commence to flow through the outlet 6 as soon as
it rises in the reservoir above the point 14 or line AB (see Figs. 2 and 3) but
that it will not flow over the "bye-wash" 7 (Fig. 2) or through the opening 10
(Fig. 3) until it rises above the line CD so that unless the water in the
reservoir rises rapidly the surplus "or overflow will be drawn entirely from the
bottom of the reservoir and that water which has been longest therein.
When the water in the reservoir falls below' the point 14 it immediately ceases
to be discharged through the outlet 6.
The water from the reservoir 2 is supplied to the "main" pipe or pipes in the
"usual manner.

page_text: 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 application and use of the appliances for withdrawing the surplus water from
reservoirs or other water stores in the manner, and for the purpose herein described
and substantially as illustrated by the annexed drawings.
