Year: 1884

page_text: I GEORGE WILLIAM CHINNERY of 5 Richmond Rd, Queens Road, West,
Walthamstow, in the County of Essex, Marine and Mechanical Engineer do
hereby declare the nature of my invention for IMPROVED APPARATUS FOR
MAKING AND SUPPLYING AERATED DRINKS to be as follows:-
My Invention has for its object an "Improved Portable Apparatus for the
making and supplying Aërated Drinks," and in order to do this, I construct the
apparatus as follows.
First, I make a vessel of steel, malleable-iron, or other suitable metal, coated
internally, and occasionally externally with, enamel, silver, tin, or other suitable
material, the said vessel containing from 3 pints, and upwards, and being in the
the shape of a sphere, or elongated-sphere-preferably, in two seperate halves,
united by means of flanges, bolts and nuts, or a union-joint, & screw, or other
suitable appliances, with some soft material between, on the top, (or possibly at the
bottom) of the aforesaid vessel, I screw on, or connect another smaller vessel, the
shape of an ovoid, or preferably the shape of the vertical steam-dome of -an
ordinary steam-boiler, having internally a tube rising nearly to the top of the
upper-vessel, and passing through an aperture into the vessel below. At the
bottom of, and secured to, the lower-vessel I fit a knuckle-joint, secured to a stand,
or base of suitable material; by means of said-joint, I cause the vessel to incline as
may be desired, for the purpose of cleansing, the interior, and also for agitating, or
mixing the ingredients within, as well as supporting the vessels by means of said
knuckle-joint, I also fit springs to maintain the vessel in a vertical position when
desired. At the side of the upper, and also at, or near the base of the lower vessels
I fit a small tube, or nozzle with cap, plug, or tap, for the purpose of draining off,
and cleansing the interior of the vessels when desired.
On the lower vessel I fit at a convenient height, an high-pressure tap, having an
internally-descending tube for the purpose of drawing off, and serving on draught,
the liquor within.
On the upper vessel, in a convenient position I fit a screw-cap, or nut, having an
internally-fitted plug, or washer, with a ring of India-rubber, (or more suitable

page_text: material) the said plug entering an aperture in a screwed-boss on the upper vessel,
or I may prefer to use an hinged man-hole cover form of arrangement, secured by
screws, or some more suitable appliance-the above-mentioned aperture being used
for the purpose of filling, and charging the vessels beneath, the whole of the
aforesaid vessels being tested to an hydraulic pressure of 200 lbs to the square
inch.
At, or about the joint of the two halves of the lower vessel I fit a cylindrical, or
other-shaped, (in some instances annular-shaped) hollow vessel of suitable material
extending nearly to the top of upper vessel to be used as an ice-box, or refrigerator
or receptacle for non-conducting material for the purpose of keeping the gas, and
liquids at a low temperature, said vessel having a small draw-off-tap for water.
The apparatus generally to be encircled or covered with an inverted circular or
other shaped dome of pulp, or other material, resting on the base, &c. the said
cover, (or possibly the above-mentioned ice-box) having arranged, and secured
around it various receptacles, of glass, or other material (with small taps), for
holding of syrups, or other liquors.
I." charge" the apparatus as follows, first, I fill the lower vessel with the liquid
to be aërated, and then having inserted a temporary-plug in the tube of upper-
vessel, I insert alkali, and acid, and a small portion of water, then removing the
plug, I put on the cap, or other appliances, and the carbonic-acid gas, resulting
from the above mentioned mixture immediately commences to aërate the liquid
below, from whence I draw it off as may be desired on any syrup or other liquid.

Improved Apparatus for the Making and Supplying Aërated
Drinks.
I, GEORGE WILLIAM CHINNERY of 5 Richmond Road, Queen's Road West
Walthamstow Essex, Engineer do hereby declare the nature of my invention for
IMPROVED APPARATUS FOR THE MAKING AND SUPPLYING AERATED DRINKS and
in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement:-
This invention will be best understood. by reference to the accompanying
drawings in which Figure 1 is a vertical section of the apparatus Figure 2 an
elevation taken in a vertical plane at right angles to that of the section Figure 1;
Figure 3 an elevation in the same vertical plano as Figure 1, and Figure 4 a detail
of the cap.
Like letters represent like parts in the different views.
A is the lower chamber or vessel in which is placed the water or other liquid to
be aerated. This may be spherical or other suitable shape but the form shown in
the drawing in which the vertical axis is longer than the horizontal ono is
preferred. With this shape the weakest part is the straight piece at or near the
cer tral junction line and this part is strengthened by the flanges B. B. (of which
there is one to each half or part of the vessel) which extend entirely round the
vessel and serve for securing the two parts of the vessel together by bolts C in the
ordinary manner.
The tap D for drawing off the contents of the vessel A is preferably placed
about half way up the side say upon a boss D' Figure 2 extending from the
vessel just above the upper flange and long enough to carry the top clear of the
flange cover &-Inside the vessel extends the pipe or channel D' to the bottom
so as to permit of approximately the whole of the contents being drawn off at the
tap D.
The pipe E extends from the lower vessel A inside the upper vessel F to near
its top and is preferably placed a little out of the centro so as to allow of F being
charged through the aperture F and clear of the pipe E. The position of the
aperture F¹ could however be changed if desired but the arrangement shown is
preferred.
The upper vessel or dome F is secured to A in any suitable manner but preferably
in the manner shown in Figure 1 where it fits round a portion projecting beyond
the seat and is secured by studs or bolts and nuts as shown. It may however be
screwed on to a projecting boss in the same way that the cap G is fitted. This
dome F may be of any suitable shape.
The cap G screws on to the branch F2 so as to close the aperture F¹, and as very
great difficulty is experienced in making such a joint so secure as to resist a heavy
pressure of gas I have adopted the following means which will be better understood
by the enlarged view Figure 4.
.

page_text: Upon the end of branch F' I place the brass or similar plug H which fits into the
aperturo Fl and carries the india rubber washer H. The cap G is screwed down
upon the plug H and the washer H¹ is squeezed between the plug and the end of
the branch F thus making a perfectly tight joint. By this means the rubber
washer is not turned round as would be the case if the cap G pressed directly
upon it; such turning besides spoiling the rubber is almost certain to crumple it
and work it into bills and hollows so that it becomes extremely difficult to make a
tight joint.
The cap G may be screwed on with a spanner but to prevent unauthorised
persons tampering with the machine I prefer to adopt a special form so that the
cap cannot be removed without the proper spanner.
The ice box I is an annular vessel which fits over the dome F and rests upon the
upper portion of A to which it is fitted; it may be provided with a drain tap or
plug and its general shape and arrangement is clearly shown in Figure 1.
The vessels K which are arranged around the apparatus may be supported in
perforated plates secured upon the bolts C; they are intended to contain the
various syrups which may be wanted.
At the bottom of vessel A is a projecting lug L which fits in the jaw M of the
stand N the bolt O connecting the two and completing the joint or hinge. The
amount of movement of this joint is limited by the jaw M which is squared at
the top and nearly reaches the bottom of chamber A so that when the latter is
pulled over sufficiently far the two parts come in contact with one another and
stop further movement in that direction. The apparatus is kept upright except
when pulled over by the springs P. Q. which act against each other but allow of
the movement just described and which is useful for shaking up the contents &°.
The form shown in Figure 3 is the same as the others but a nonconducting
cover R is placed over the whole apparatus the vessels K being let into holes in a
broad flange R' which surrounds the vessel. The slot R³ is to permit the passage
of the tap D when the cover is placed on or withdrawn. This cover R may
generally be dispensed with in temperate climates.
The plugs A³ and F are for draining their respective vessels.
This apparatus may be constructed of the ordinary materials used for such
purposes such for instance as copper but this I object to on account of the bad
effect upon the contents after they have lain in the vessel a little time.
I thereforo prefer to employ steel or malleable cast iron or the like coated
internally (and externally also if desired) with enamel, or other acid resisting
material so that the contents may be left in the vessel for an indefinite time
without deteriorating.
As an apparatus of this kind has to stand very heavy internal pressure it must
be very strong and I find by constructing it of the materials and form indicated
that it will safely resist a pressure of two to three hundred pounds to the inch.
The apparatus may be charged as follows:-
•
- I place in the lower vessel the liquid to be aerated, and then having inserted a
temporary plug in the top of pipe E so as to close it for the time being I place the
soda and acid and a small portion of water in the upper vessel F and then removing
the temporary plug I place the plug H with its rubber washer on the branch
and screw on the cap G. The gas which is generated in F pas-es by the tubo E to
the lower vessel A and impregnates the liquid therein in the usual manner and
being thus put under pressure it can be drawn off at the tap D.
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 apparatus such as described an approximately spherical vessel A which
is made preferably of malleable. cast iron and coated inside with enamel, A. being so
formed that the length of the vertical axis is greater than that of the horizontal

page_text: axis being divided into two halves or portions in such manner that the flanges B
by which the two parts are held together are at the weakest part of the vessel
where they act as strengthening ribs all substantially as specified and illustrated in
the accompanying drawings.
2.-In an apparatus such as described the combination with a vessel such as A
of the joint L M which permits an oscillating movement of the vessel and springs
P. Q. which return the vessel to its normal position when released substantially as
specified and shewn in Figure 2 of the accompanying drawings.
3. In an apparatus such as described the combination with a vessel such as A
of a joint L M which whilst permitting an oscillating Inovement of the vessel limits
the extent thereof substantially as specified.
4. As a means of making a tight joint in a soda water or other machine
containing gases under pressure the combination with the ordinary screw cap G
and branch F2 of the plug H and rubber washer H₁ substantially in the manner
specified and shewn in Figure 4 of the accompanying drawings.
5.-The combination with an apparatus such as described of an annular ice box I
adapted to be placed upon and around it and whoso interior walls are recessed to
accommodate a vessel such as A substantially as specified and shewn in Figure 1 of
the accompanying drawings.
6. In an apparatus such as described the combination with the vessel A of
vessels K arranged about said vessel A in the manner specified and adapted to
contain syrups, essences, and the like for use with the aërated drinks supplied from
vessel A.
