My invention relates to an improved means for regulating the height of water
in cylinders or condensers of ærated water machines, and consists of a float
operating a valve which controls a communication through pipes .between the
cylinder or condenser and the ærated water pump. The float may be placed in the
cylinder,; or in a separate. vessel suitably connected to the cylinder, in such a
manner that when,, water rises in the cylinder above a predetermined level the
float rises opening the valve and establishing communication between the cylinder
and the pump, filling the pump on its suction stroke and thus, preventing, it
drawing water through the suction valve... A check valve may be placed between
the valve operated by the float and the pump. When the float is hollow I take a
pipe from the inlet side of the valve, operated by the float, into the float and so
arranged that when the valve, opens all moisture is carried away. I also attach a
cock in communication with this pipe to provide a further means of blowing
moisture or water out of the float.

I, NATHANIEL SAINT GEORGE WILCOCKS, of the Bath City Brass Foundry and
Ironworks, 45, Avon Street, Bath. in the County of Somerset, Engineer, 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 invention consists of a vessel connected to the cylinder of an æerated water
machine in such a manner that when the level of the water rises in the cylinder
it also rises in the vessel and by lifting a float placed therein opens a valve allowing
sufficient gas or water to pass from the cylinder to the pump to fill the latter on its
suction stroke and to keep the suction valve closed; in this way preventing the
pump receiving its charge of gas and water or gas only or water only through its

page_text: suction valve and thus not allowing any more water to be delivered into the
cylinder untill the water level has been lowered sufficiently to allow the float to
fall and by closing the valve allow the pump to draw its charge through the suction
valve. The accompanying drawing is a longitudinal partly sectional elevation.
1 represents a preferably gunmetal vessel containing a hollow float 2 with its
arm 3 working on a pin 4 and operating the valve a pipe 6 passes through the
aperture 6³ and reaches nearly to the bottom of the float 2 and is continued by the
passage 61 to the valve 5. Above the valve 5 I place a check valve 7 to take
the delivery pressure of the pump. A pipe 8 leads to the valve chamber 9 of the
pump 10. The pipe 11 is continued to the cylinder and connected to it as near the
top as possible, and the pipe 12 is continued to the cylinder and connected to it as
near the bottom as possible. A bracket 13 provided with a slot in which a bolt 14
may slide gives vertical adjustment for the vessel 1. A drain cock 15 is provided
to use if required to drain water from the float 2.
1
The action is as follows: the vessel 1 being adjusted to the required height
in relation to the desired height or level of the water in the cylinder of the ærated
water machine, the water passes from the cylinder through the pipe 12 into the
vessel 1 and lifts the float 2 which opens the valve 5 compressed gas passes through
the aperture 6 and together with any water from condensation or leakage which
may have accumulated sufficiently in the float 2 now passes by the pipe 6 and
passage 61 through valves 5 and 7 and pipe 8 to valve chamber 9 and pump 10
completely filling the pump and closing the suction valve 16. The pump on its
delivery stroke closes the valve 7 and delivers its contents into the cylinder in the
usual way and on its suction stroke is again filled by pressure from the cylinder
through the valve 5 the suction valve 16 remaining closed. This action
continues until the water in the cylinder is drawn off and allows the float 2 to fall
and close the valve 5 when the pump will draw its water and gas through, the
suction valve 16 in the usual way.
When the connecting pipe 8 is unduly long or when the valve 5 is connected to
two or more pumps I use a check valve 17.
It is obvious the pipe 8 may be connected to any other portion of the pump
provided the pressure it delivers will close the suction valve 16.
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::
1. In an ærated water machine the combination of a vessel such as I with
float 2 valve 5 pipe 6 cock 15 and valve 7 substantially as herein described and
shown by the accompanying drawing.
2. In an æerated water, machine valve 17 as herein described and shown on
accompanying drawing.
i
3. In an ærated water machine a valve such as 5 controlling a communication
between the cylinder and the pump or pumps for the purpose of admitting water or
gas to the pump or pumps from the cylinder when the water in the latter rises
above its required level.
