COMPLETE SPECIFICATION.
Improvements in and connected with Water Supply.
I, EDWARD DRAKE BERTINE, of New York, County and State of New York,
United States of America, Builder, 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 an improved feed tank that receives the water from the
main and delivers it to the distributing pipes or to the pump to insure a uniform
pressure.
The invention consists in the various features of improvement more fully pointed
out in the claim.
In the accompanying drawing Fig. 1 is an elevation of the tank showing it connected
to the pump.
Fig. 2 is a detail vertical central section of the tank.
The letter a, represents a tank made of metal and preferably of cylindrical form.
The tank is connected both with the water supply and the water discharge pipes.
These pipes enter the tank from opposite sides and the mouth 6, of the water
supply pipe b, is located a considerable distance above the mouth c', of the discharge
pipe c. The pipe b, receives the water from the main and delivers it to the tank a.
It should be provided with a valve 63, to stop or check the supply of water to the
tank. From the pipe b, there extend upwardly two more or less rising pipes 68, 64,
that deliver water directly to the lower stories of a building.
•
The discharge pipe c, communicates with a pump d, which pumps the water into a
rising pipe d, that delivers it to the roof tank, or the pipe c, may be directly
connected to the rising pipe or pipes.
At a bend of pipe c, there should be placed the air chainber d³, to collect the air
from the water.
At the upper part of tank a, there is placed an air cock a', and into the lower
part of tank a, there enters an emptying pipe a³, having cock a³. In order to
properly clean the tank, it should be provided with a hand hole a*.
The operation of the device is as follows:
The water from the supply pipe flows into the tank a, and forces air contained in
said tank into the upper part of the same as shown ate. The pressure of this air cushion
will, in time, be sufficient to check the water supply, unless an equal amount of water
is drawn out. As the mouth c¹, is located beneath the mouth 61, the air will not force
the water up the pipe c, but the water will be taken up by the pump only in such
quantities as the pump can conveniently handle. In this way, the pump will not
choke up, but will work uniformly and without thumping. If no pump is used, the
pressure in all the rising pipes connected with pipe c, will be uniform.
Any sediments contained in the water will collect in the lower part of the tank a,
and may be removed by the hand hole.
The outside pipes 6, 64, are used only in case a pump is also used. They will
receive their water before the tank is supplied and thus there will always be a free
flow into such pipes whether the pump is worked or not. Thus the objection, that
the lower stories must suffer a temporary absence of water, while the pump is worked,
is overcome.
When the pump has completed its work, the lever 6³, is closed and the cocks a¹, a³,
are opened. This will permit the air and waste water to escape.
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:
1. The combination of a tank having an air cock, with a water supply DiDe

page_text: connected to the main and with a water discharge pipe for distributing the water,
the water supply pipe entering the tank above the water discharge pipe substantially
as specified.
2. The combination of a tank with a water supply pipe connected to the main, a
water discharge pipe entering the tank below the water supply pipe and with an air
cock within the upper part of the tank and a water emptying pipe connected to the
lower part of the tank, substantially as specified.
3. The combination of tank a, having valve a', with emptying pipe a², having valve a³,
water supply pipe b, having valve 63, and rising pipe 6, and with water discharge
pipe c, entering the tank below pipe b, the tank a, being interposed between the
pipes 6, and c, substantially as specified.
