Supplying Gauged Quantities of Liquids.
I, THOMAS SHAW COCKCROFT, of 3 to 13 Egerton Street, Birkenhead in the County
of Chester, Mineral Water Manufacturer do hereby declare the nature of my said
invention to be as follows :-
My Invention relates to apparatus for measuring quantities of liquid, such as measuring
quantities of syrup in aërated water bottling; drawing quantities of liquid such as
oils, or alcoholic, or other liquids, and consists in so constructing and connecting the
measuring device with the supply that the measuring device is self filling, and is
discharged by a valve which closes the supply, the action of the valve being positive,
namely when the supply is open to the measure, the discharge port of the valve is
closed and when the discharge port is opened the supply port is closed. The measure
may be a cylinder having a piston, the stroke of which is capable of variation, so that
the capacity of the measure can be changed as required. For example the measure
may be of size and adjusted to contain when used for syruping in aërated water
bottling, one ounce, two ounces, three ounces, or it may be of size and adjusted to
contain a gill, a pint, a quart, a gallon, or other quantity as desired when used for
drawing alcoholic liquids, or other liquids, or oils. For example the measure, which
may be a cylinder, is separated from the supply vessel by the positive valve and the
supply vessel is placed at a higher level than the measure, so upon opening the valve
to the supply the measure will fill and be charged with the quantity of liquid for which
it is set, which quantity is regulated by adjusting the stroke of the piston, which rises
as the measure fills, so that the measure will be, say, one ounce, two ounces, three
ounces, or other quantity. To empty the measure the valve is closed to the supply and
opened to the discharge, the piston falling as the measure empties. To obtain a record
of the amount drawn, or discharged, the piston, or plunger of the measure may be
arranged to operate a registering device, such as a Harding's, or like Counter, having
dials which are marked to correspond with the variations of the measure.

I THOMAS SHAW COCKCROFT, of 3 to 13 Egerton Street, Birkenhead, in the County
of Chester, Mineral Water Manufacturer, do hereby declare the nature of my said
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 apparatus for measuring quantities of liquid, such as
measuring quantities of syrup in aërated water bottling; drawing quantities of liquid
such as oils or alcoholic or other liquids and consists in so constructing and connecting
the measuring device with the supply that the measuring device is self filling, and is
discharged by a valve which closes the supply, the action of the valve being positive,
namely when the supply is open to the measure the discharge port of the valve is closed
and when the discharge port is opened the supply port is closed. The measure may be
a cylinder having a piston, the stroke of which is capable of variation, so that the
capacity of the measure can be changed as required. For example the measure may
be of size and adjusted to contain when used for syruping in aërated water bottling,
one ounce, two ounces, three ounces, or it may be of size and adjusted to contain a gill,
a pint, a quart, a gallon, or other quantity as desired when used for drawing alcoholic
liquids, or other liquids or oils. For example the measure which may be a cylinder is
separated from the supply vessel by the positive valve and the supply vessel is placed
at a higher level than the measure, so upon opening the valve to the supply the measure
will fill and be charged with the quantity of liquid for which it is set, which quantity
is regulated by adjusting the stroke of the piston, which rises as the measure fills, so
that the measure will be, say, one ounce, two ounces, three ounces, or other quantity.
To empty the measure the valve is closed to the supply and opened to the discharge,
the piston falling as the measure empties. To obtain a record of the amount drawn,
or discharged, the piston or plunger of the measure may be arranged to operate a
registering device such as a Harding's or like Counter, having dials which are marked
to correspond with the variations of the measure.
In order that my Invention may be clearly understood, I will now proceed to more
particularly describe the same with the aid of the accompanying two sheets of
Drawings which illustrate an apparatus according to my Invention. The Drawings
are marked with figures and letters of reference corresponding with those used in the
following explanation and like letters are used to denote like parts throughout the
several Figures.
DESCRIPTION OF THE DRAWINGS.
Figure 1 is an elevation of an apparatus according to my Invention.
Figure 2 is a sectional elevation of the apparatus.
Figure 3 is a plan of the apparatus shown in section through a Figure 1.
Figure 4 is sectional elevation of the apparatus through a Figure 3.
The example of my Invention shown in the Drawings illustrates an apparatus for
measuring quantities of syrup in aerated water bottling. In the Drawings A is the
measuring vessel. B is the positive valve, which is so placed between the measuring
vessel A and the supply duct C that the measuring vessel A is self filling by means of

page_text: the valve B. The valve B is of the "plug" type and its seat D is formed in the
branch E containing the supply duct C. The measuring vessel A consists of a cylindrical
glass tube a held in a metal case d between the face e of the branch E and a packing
gland F. Within the vessel A there is a piston H the upper end of which passes
through the gland F and through a guide I provided with holes i and a pinj so that
the stroke of the piston H can be adjusted by setting the pin through the required
holes and thus the capacity of the vessel can be regulated, for example to contain one
ounce,
two ounces, three ounces or other quantity as required. The valve B is provided
with a handle B' and a nozzle B2 and with a duct which forms the duct of the
nozzle B² and with two ports k. l. The valve seat, or case D has also two ports mn.
These ports are so formed and placed that the port will, on turning the valve B,
open the supply duct C to the port m and so to the vessel A to fill the vessel, and
when the vessel is full, by turning the valve B in a reverse direction the ports and m
are closed, and the vessel is open to the discharge duct b and nozzle B2 through the
ports n and l.
The supply duct C is connected to a supply vessel which is placed at a higher
level than the measuring vessel A so that upon opening the valve B to the duct the
measure A will by the head or pressure of the liquid fill and be charged with the
quantity of liquid for which it is set, the piston H rising to the gauge pin or stop j.
When full the measure A is emptied by reversing the movement of the valve B so
that it is closed to the supply and open to discharge the contents of the measure A
through the nozzle B2, the piston H falling as the measure A empties.
To obtain a record of the amount drawn from the supply the piston H may be
connected by a rod and lever to a registering device of any known and suitable kind,
such as a «
Harding's "Counter, the dials of which are marked to correspond with the
variations of the measure.
I would have it understood that the device shown in the Drawings is only given as
an example of an apparatus according to my Invention and that the design and detail
can be varied without departing from my Invention, namely the form of valve and the
form of measure may be changed to suit the different conditions of the application to
which it may be put.
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:
First. In an apparatus for discharging or supplying gauged quantities of liquids, a
cylinder having a plunger working therein, or their equivalent, the ingress and egress
passages to which are controlled by a positively operated tap or taps, valve or valves
substantially as set forth.
Second. An Apparatus for discharging or supplying gauged quantities of liquids in
which a single tap or valve is adapted to form communication alternately with a cylinder
provided with a plunger, or their equivalent, and a supply vessel, and the cylinder and
the exit duct of the apparatus substantially as set forth.
Third. The Apparatus described for measuring quantities of syrup in aërated water
bottling, or like purposes, having a measuring vessel A, a supply duct C and a positively
operated valve B substantially as set forth and as shown in the Drawings hereto
annexed.
