PROVISIONAL SPECIFICATION.
Improved Apparatus for Discharging Aerated Liquids.
I, MORTIMER EVANS, of Savile Club, Piccadilly, Engineer, do hereby declare
the nature of the said invention to be as follows:-
This invention relates generally to an improved arrangement of apparatus to be
employed in discharging regulated or other quantities of aerated liquids, and
specifically to a new and improved formation of the container of the portions of
liquid to be discharged and to improved means used in connection therewith of
elosing and unstopping the outlet aperture from such container such latter
improvements being specially designed to dispense with and avoid the dis-
advantages of the use of all tortuous valvular and tap devices ordinarily used,
which tend in the act of discharging the liquid to mechanically effect the disengage-
ment of the occluded gas from the aerated liquid, rendering the latter "flat and
more or less unpalatable, and to permit of the unimpeded escape of the aerated
liquid without liability to such disengagement of its contained gas.
To the aforesaid end, the invention consists in the application to such apparatus
of a container (which may be made of any desired capacity) formed with a
depending outlet of any sufficient area relatively to the capacity of the container,
and so as to avoid all sharp angles or the like and to present to the escaping
liquid a smooth, rounded and unimpeded gradually contracting outlet.
The upper end of such container is gradually contracted and is cemented, packed
or otherwise equivalently secured in a suitable mounting, which serves as a means
for bolting or otherwise suitably securing the apparatus to any suitable support,
and also serves to support the operating details of a rounded valve having its
seating at and closing the inner end of the outlet opening from the container, such
operating details being so arranged as to cause the valve to normally close the said
outlet opening and as that the operation thereof as hereinafter described shall raise
the valve entirely away from the said outlet opening, so as, as aforesaid, to leave
the same free and unimpeded for the escape of the aerated liquid.
Such raising of the valve clear from the outlet opening from the container is
effected by the depression or other convenient actuation of a conveniently placed
handle, also preferably supported by the said mounting and overlying a rod
connected to the valve operating details and projecting from the said mounting.
Excepting when thus actuated, the handle is independent of the said valve, so
that, by its connection with an ordinary three-way cock or equivalent means orossing
a passage in the mounting leading from a suitably placed reservoir of the aerated
liquid to the upper end of the said container, it can, without actuating the said
valve controlling the outlet from the container, be successively moved into such
position as will place the reservoir and container in communication for charging the
latter, close off such communication so as to confine the charge next to be drawn
within the container, and open an escape through the said three-way cock for or
actuate other or equivalent means of effecting the relief of any excess pressure
within the container, immediately before its actuation (as aforesaid) of the said
independent valve, which latter thereupon permits of the free and unimpeded escape
of the aerated liquid from the container with the advantage herein before referred to.

Improved Apparatus for Discharging Aerated Liquids.
I, MORTIMER EVANS, of Savile Club, Piccadilly, 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 :-
This invention relates generally to an improved arrangement of apparatus to be
employed in discharging regulated or other quantities of aerated liquids, and
specifically to a new and improved formation of the container of the portions of
liquid to be discharged, and to improved means to be used conjunctively therewith for
closing and unstopping the outlet aperture from such container.
The improvements lastly referred to have been specially designed with the objects
of dispensing with and avoiding the disadvantages of the tortuous valvular and tap
devices ordinarily used (which tend, in the act of discharging the liquid, to
mechanically effect the disengagement of the occluded gas from the aërated liquid.
and so render the latter "flat" and more or less unpalatable), and of permitting of
the unimpeded escape of the aërated liquid without liability of such disengagement
of its contained gas.
On the accompanying drawings, Figures 1 to 5 represent sectional elevations
of two modifications of the invention. Figures 1 and 2, are sectional elevations
on the same plane, and represent two positions of the modification therein repre-
sented. Figure 4, is a section on the plane indicated by the line a-, Figure 3,
looking in the direction of the arrow ; and Figure 5, is a section on the plane
indicated by the line de, Figure 3, looking in the direction of the arrow
A special feature of the invention consists in the application to and use in
such apparatus of a container 6, made (of any desired capacity) of a globular,
prolate ellipsoidal, or cylindrical formation with semi-spherical or equivalently
rounded ends, or of any analogous formation (avoiding angular formations or the
like), and gradually merging at the one end into a depending outlet 7, of any sufficient
area relatively to the capacity of the container and presenting to the escaping liquid a
smooth rounded and unimpeded gradually contracting outlet, and in like manner
gradually merging at the upper end into a neck-inlet 8, of convenient area and
shape for attachment to a suitable supporting mounting 9.
The inlet-neck S, of the container 6, is preferably formed with a rim 10, and is
secured within the mounting 9, by a split collar 11, about which the mounting 9,
is screwed so as to compress an elastic washer 12, between the rim 10, and an
opposite ledge 13, formed within the mounting. The inlet-neck of the container
may, however, be connected or otherwise than as aforesaid suitably attached to the
mounting 9.
There is used, according to the present improvements, in conjunction with such
a container, an extensible and collapsible vertically-acting valve 14, having its
seating at and being adapted to close the immer end of the outlet 7, from the
container.
The operating details of such valve are so arranged as to cause the valve to
normally close the outlet 7, and, when they are operated and in action, as to
cause the valve to be raised entirely away from the aid outlet (eide Fig. 21, so as
as aforesaid, to leave the same unimpeded for the free escape of the aerated
liquid.
The mounting 9, in addition to supporting the container, as aforesaid, serves
also to support the operating details of the Said valve, and the means controlling
the admission of the liquid to the container, and also serves as a means of securing
the whole apparatus to a counter, wall or any other convenient support 15.
The valve 14, is made of a rounded or other equivalent formation adapted to
close the outlet 7, as represented in Figs. 1, 3 & 4, and is preferably adapted with
a projecting elastic washer 16, adapted to abut against the inner sides of said

page_text: outlet. The valve may be made in parts securing the washer 16, between them,
as represented in Figure 3, or in any other suitable manner, and it may be hooked
to or otherwise freely suspended. at 17, to an operating rod 18. so as to permit
of its descending into the said outlet and efficiently closing the same.
In the modification represented in Figures 1 and 2. the raising of the valve 14,
is effected by a lazy-tong arrangement 19, which is centred at 20, one end being
connected at 21, to a guided operating rod 18 and the other end being connecteil
The whole device is
at 23, by a guided pivotal attachment to the valve rod 22.
carried by a bridge 24, depending from a closing cap-nut 25, screwing into the
top end of the mounting 9. The pivots 20, 21, 23, of the lazytongs, respectively
work in opposite slots 26, 27, 28, of appropriate lengths, formed in a supporting
tube 29, depending from the bridge 24; and the levers of the lazytongs are guided
in other slots (not shown) made in the opposite sides of the tube 29. A spring 30,
arranged between the pivots 20, 23, normally tends to distend the same and to
keep the valve 14, against its seating in the outlet 7, and to automatically return
it thereto when the actuating handle 31, is not in action. The spring 30, may be
replaced by a spring in tension normally tending to draw the opposite side pivotal
connections of the lazytong levers together. The rod 18, is fitted with a valve-
piece 32, adapted to close the aperture 33, in the cap-nut 25, through which the
rod 18, works, when the valve 14, is on its seating in the outlet 7. The provision
of the slots 26, for the pin 20, enables the spring 30, to ensure both valves 14, 32,
abutting against the openings they respectively control.
In the modification represented in Figures 3 to 5, the raising of the rod 18, and
attached valve 14, is effected by gearing operated (as in the modification herein-
before described) at the appropriate time, by the means controlling the admission
of the liquid to the container. Such gearing consists of a segment 34, which
actuates the former of two connected wheels 35, 36, the latter of which gears with
a racked portion of the rod 18. The pivots 37, 38, of the wheels 34, 36, and the
rod 18, are supported by a bracket 24, depending from a tubular closing piece 25,
The return
which is secured to the mounting 9, by an annular screw-cap 25*.
of the valve 14, to its seating at the outlet 7, when not under the control of the
means which cause it to be raised from the seating, is effected by a spring 30,
connected as represented in Figure 4, or in any other suitable manner.
The raising of the valve 14, is effected in the modification represented in
The handle is connected
Figures and 2, by depressing the handle 31. ride Fig. 2.
to an ordinary three-way cock 39, or to other equivalent or suitable means of
consecutively admitting the aerated liquid from the supply 40, through a port 41,
to the container 6 and, after closing such through connection, letting off the
surplus pressure of gas in the container 6, through a connection then formed
between the port 41, and an exit opening 42, (ride Figure 1) so as to allow
(consequent upon the continued depression of the handle, ride Figure 2, during
which the exit passage 42, may remain in communication with the container 6,) of
the unimpeded gravitating and escape of the aerated liquid from the container
without any such disengagement as aforesaid of its occluded gas.
In the modification represented in Figures 3 to 5, the raising of the valve 14, is
effected by a projection 43, on the adjacent end of the cock 39, abutting against and
actuating the segment 34, on the continued turning of the handle 31, after the
charging of the container (eide Figure 3) and relief of its superfluous pressure
therein on the further turning of the handle, have been effected.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. The combination. in apparatus for discharging aerated liquids, of a container
of the improved formation hereinbefore described with means operating in the
manner herein before described for closing and unstopping the depending outlet
thereof.

page_text: 2. The arrangement of such apparatus hereinbefore described with reference to
Figures 1 and 2 of the accompanying drawings.
3. The arrangement of such apparatus hereinbefore described with reference to
Figures 3, 4 and 5 of the accompanying drawings.
4. The application to apparatus for discharging aerated liquids of means
operating in the manner hereinbefore described for controlling the outlet of the
container thereof.
