PROVISIONAL SPECIFICATION.
An Improvement for Augmenting the Delivering Capacity of the
Mains of Gravitation Water Supply Systems.
I, JOSEPH BOWMAN WILSON, of Rose Mount, Papcastle, Cockermouth, in the
County of Cumberland, Civil Engineer, do hereby declare the nature of this
invention to be as follows:-
'
The improvement for augmenting the delivering capacity of the mains of
gravitation water supply systems consists in attaching to the mains, at suitable
places, centrifugal or other suitable forms of pumps, which may be driven by
steam engines, gas engines, oil engines, turbines and other hydraulic engines
driven by water from extraneous sources.
The mains at the points where the pumps are placed are disconnected, the lower
ends of the upper parts of the mains being connected to the suctions of the pumps,
and the upper ends of the lower parts of the mains are joined to the deliveries
of the pumps, by which arrangement the water passing down the mains is made
to pass through the pumps, and the speed and capacities of the pumps is such
that they are capable of delivering a greater quantity of water than the mains
would deliver by the force of gravity alone; the flow of water in the upper
lengths of the mains is accelerated by the sucking action of the pumps, and in
the lower lengths of the mains the water is further accelerated by the forcing
uction of the pumps.
Standpipes or air-vessels, or standpipes and air vessels, are attached to the
mains to prevent shocks thereto.
The improvement for augmenting the delivering capacity of the mains of
gravitation water supply systems may be applied to one or more of the mains.
By means of the improvement herein described cities, towns, and districts,
whose populations have increased until the supply of water needed has outgrown
the capacities of the water mains of gravitation systems, may be saved the heavy
expenditure that has to be incurred in laying a new set of mains, and the present
supply of water largely increased at but a relatively trifling cost.
The improvement can also be used in new works of water supply.

I, JOSEPH BOWMAN WILSON, of Rose Mount, Papcastle, Cockermouth, in the
County of Cumberland, Civil Engineer, do hereby declare the nature of this

page_text: invention and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement:-
The improvement for augmenting the delivering capacity of the mains of
gravition water supply systems consists in attaching to the main, at fitting places,
centrifugal or other suitable forms of pumps, in a manner that will permit the
water in the mains to pass through them, the pumps being driven by any suitable
motor, such as turbines, steam engines, gas engines, oil engines, compressed air
engines, or electro motors.
Figure 1 of Sheet 1, of the drawings shows in elevation one form of the inven-
tion wherein a centrifugal pump is used, and is driven by a turbine by means of
bevel gear; the water used for the turbine being obtained by utilising the com-
pensation water to be returned to the source for other purposes, or from a source
extraneous to that of the water supply. Figure 2 is a plan of the arrangement
shown by Figure 1. (a) is the main whose delivering capacity it is desired to
increase; (b) is the centrifugal pump which is driven by gearing, as indicated
by the dotted lines, actuated by a turbine (c). The water for working the turbine
is conveyed to it by the pipo (d) and leaves by the pipe (e).
Figure 3, shows in sectional elevation the adaptation of a form of screw pump
which may be used instead of a centrifugal pump, to increase the flow of water
in the mains when attached thereto, in the manner shown; any suitable motor
and driving mechanism may be used to work it. (a) is the main, and (b) the
screw-pump.
By passing the water of a main through a pump driven by motors, the water
in that main can be driven, at a higher velocity, consequently enabling a larger
quantity of water to be supplied by the main.
The advantages of the invention are that should a district through which a
water main passes require a greater quantity of water than the existing main
can, under its present condition, supply, that supply can be augmented without
laying a second or larger main. Again, in the event of a district at a higher
elevation than that arranged for when the water supply was originally designed
be built upon, the wants of such a district could be met by means of the invention
herein described, the pumps being able to deliver the water to the higher level,
as already stated, without interfering with the general arrangement of the water
system.
The two forms of pumps shown by the drawings are the most suitable for
carrying out this invention, but the inventor does not confine himself to these
only, as others may be used; neither does he claim as part of this invention
centrifugal pumps, screw pumps, or any other form of pump for lifting or forcing
water as they are old, as is also the use of the turbines, steam engines, and the
like motors for driving them for the use of which also no claim is made.
Spur and bevel gearing have been shown as suitable for driving the pumps,
but these may be driven by means of belting, or be driven direct by steam engines
or other motors,
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:-
-
Augmenting the quantities of water delivered by a main or mains of gravita-
tion water supplies by inserting in a length or lengths of a main or mains pumps,
driven by turbines, steam engines, gas engines, oil engines, or other motors,
through which the water in the mains can pass and the quantity delivered by
the mains or the pressure therein be increased.
