PROVISIONAL SPECIFICATION.
A Method of and Means for Regulating the Quantity of Water in
the Cylinders or Condensers of Aerated Water Machines.

I BENJAMIN SHAW, 1 Upper Head Row, Huddersfield, in the County of
Yorkshire Aerated Mineral Water Manufacturer do hereby declare the nature of
this invention to be as follows:-
My invention relates to a method of regulating the quantity of water in the
cylinder or condensor of a soda water machine by means of which the water supply
to the pump is closed automatically when water in cylinder gets to its proper
working height, which said height each user may determine for himself, thus
ensuring a constant working limit to the height of water without any attention on
the part of the attendant.
On a suitable bracket or stand, either attached to the cylinder direct or to the
frame of the machine, or fixed in any suitable position away from the machine, is
fixed a box, preferably of gun metal, the top of which is connected with the top of
aerated water cylinder and the bottom of which is connected with the bottom of
the aerated water cylinder. Inside this box is a float, made of metal (hollow),
earthenware, or any other suitable material, to which is attached a lever com-
municating on outside of box (through suitable packing) with the water feed valve
of the soda water pump attached to machine so that when the water in cylinder or
condensor rises to the proper height the float in the box named will rise and the
lever attached to float will close the water feed valve which supplies the soda water
pump with water.
To prevent the float collapsing when made of hollow metal, on account of outside
pressure, I make a hole in float so that pressure can get inside as well as outside
and to ensure the float being free from any water that may get in through the said
hole, I make the stem hollow and a small screw on outside can be removed at any
time and any water blown out of the hole.

COMPLETE SPECIFICATION.
A Method of and Means for Regulating the Quantity of Water in
the Cylinders or Condensers of Aerated Water Machines.
I, BENJAMIN SHAW, of 1 Upperhead Row, Huddersfield, in the County of
York, Aerated Water Manufacturer, 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 relates to a new means or method of regulating the quantity of
water within the cylinder or condenser of an aerated or soda water machine, so
that the supply of a given quantity of water thereto can be automatically regulated,
and this is effected by means of a hollow or solid float working within a box or
chamber, preferably composed of gun metal.
Such being the nature and object of my invention, I will now proceed to describe
the same more fully, and for that purpose make reference to the accompanying
sheets of drawings, wherein Fig. 1 is elevation of a soda-water machine having
connected to it a pump A operated either by a steam engine or by hand power, as
will be well understood. B represents the soda-water cylinder or condenser,
supplied with water from cistern C, which water passes through pipe D, feed water

page_text: valve E, and pipe F to the pump A, which forces the said water through pipe G
into the condenser or cylinder B. The height of water within the condenser is
indicated by letter a and implies the working height which every manufacturer
fixes for himself as is well known.
It being essential to the production of good waters that the height of the water
in the cylinder or condenser B should not be allowed to exceed the level fixed
upon, whether the withdrawal of water therefrom be constant or whether it is
suspended for a short time, then recommenced and suspended again, or the with-
drawal is otherwise intermittent, I have devised self acting mechanism which, with
no attention whatever on the part of the workman, will open the valve for supplying
water to the pump when the level of the water in the condenser B is below the
maximum height, and will immediately close such valve when the maximum height
is reached. This automatic regulator which comprises my invention, consists of a
suitably shaped box or vessel H which is in communication with the condenser B
by pipe I, so that the same height of water lodges in the box H as lodges in the
condenser B. Within the said box H (which is shewn on an enlarged section at
Fig. 2 and plan view Fig. 3.) is a float J of any suitable description but preferably
hollow as shewn, and composed of metal, earthenware or other substance, which
said float works on a fulcrum b, so that as the water in the condenser B and in the
box H lowers, the float also lowers thereby causing the fulcrum 6 to turn partially
around, which, by means of link and rod d opens water feed valve E, permitting
water to pass therefrom to the pump A and to the condenser, but immediately the
water rises to the predetermined height in the condenser and box the valve E is
closed and further supply of water stopped by which means the water is kept at or
prevented from exceeding the maximum or working height without any attention on
the part of the attendant so long as the machine is at work.
€
The top of the box H is in communication, by means of pipe K with the top of
the condenser B so that the gas and water within both these vessels are at equal
pressures. To prevent the float from collapsing when made of hollow metal, on
account of the pressure of gas on the outside of the float, I make suitable apertures
or openings e in the top of the tube f to permit the gases to get to the inside of the
float so as to keep the pressure uniform. In order to let out water or moisture
which may gather within the float I make the stem 9 hollow and in communication
with a tube h, the outlet end of which is provided with a screwed cap i, which on
being removed, any moisture lying within the float can be blown out through the
said tube . Instead of the float working in a box H it may be arranged to work
in a compartment forming part of the condenser or in the condenser itself.
Fig. 4 is sectional elevation of valve E and parts connected therewith, and
Fig. 5, of the joint of the hollow stem g.
By the use of the automatic float for opening and closing the feed valve E, the
supply of water to the condenser is continuous and steady when bottling or working,
consequently the strength of the aerated waters is uniform and the waters manu-
factured are always of the same strength. When the float is solid no provision is
necessary for the egress of water as in the case of the hollow float.
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 :-
In an aerated or soda-water machine, the combination therewith of a hollow or
solid float and valve, operated in the manner substantially as herein shewn and
described and for purposes set forth.
