Improvements in the Manufacture of Aerated or Carbonated Waters
and Beverages and in the Means employed therein.
I, HENRY JAMES WOODWELL, Wine and Spirit Merchant and Bonder, residing
at the Railway Bell Hotel, Kidderminster, in the County of Worcester, do hereby
declare the nature of this invention to be as follows:-
This invention relates to aërated or carbonated waters and beverages, and con-
sists in certain improvements in their manufacture and in the means employed
therein which tend to simplify and improve the aëration or carbonating and
quicken the process.
Usually such aërated drinking beverages as soda water, champagne cider, beer,
wine and the like have been carbonated by the agitation of the gas with the liquid
in a mixing chamber or reservoir, and such mixing has sometimes been accom-
plished by revolving fans or wheels having vanes upon them. In such a manu-
facture the liquid is forced or drawn into the mixing reservoir by a pump or the
like, as also, in some cases, is the carbonic acid gas.
According to this invention the mixing reservoir, pumps etc. are dispensed with
and the carbonated liquid is formed by the uncharged liquid and gas elements
contained in it being forced and drawn through an impregnating engine or
apparatus by the existing pressure of the gas within the supply bottle or tube.
In this engine or apparatus the carbonating gas forms the medium for drawing
into the said engine the liquid which is to be impregnated, and the compressed
gas is so arranged to meet the said liquid as to split the latter up into globular
particles and thoroughly intermingle with it, the said splitting up of the water
causing the latter to quickly absorb the required amount of gas. The impregnated
liquid is then passed on to a receiver or a contrivance for using it.
The apparatus or engine consists for the most part of a barrel casing of metal
or other suitable material, within which is located the impregnating mechanism.
This barrel casing is preferably made in two parts so as to be detached for cleaning
and fitting the mechanism, and its one or delivery end is adapted to be connected
to a container or its equivalent. Centrally disposed and working within this
barrel casing is a circular spindle or stalk, having a conical head upon its one end,
which is innermost and near to the delivery end of the apparatus, and upon its
other end a handle or its equivalent for rotating the said spindle or stalk, the said
spindle being fitted with a packing gland on its handle end and mounted within a
screw box within the rear part of the apparatus so as to cause the conical head to
advance or retire longitudinally to or from a seating, a screwed part being arranged
inwards of the conical head of the stalk to engage the screw box. A small axial
hole is bored centrally through the spindle or stalk from the nose end of the conical
head as aforesaid for about half the length of the stalk and head combined, ter-
minating in crossly directed passages or holes communicating with a longitudinal
and cylindrical chamber surround the stalk which said chamber is connected, by
a branch supply, to the compressed bottle of gas through a screw union joint or

or drawn into the mixing reservoir by a pump or its like; and also in some cases
is the carbonic acid gas.
According to this invention the mixing reservoir, pumps, &c., as aforesaid, are
dispensed with, and the carbonated liquid is formed by the uncharged liquid and
gas elements contained in it being forced and drawn through an impregnating
engine or apparatus by the existing storage pressure of the gas within the supply
bottle or tube. In this engine or apparatus the carbonating gas forms the medium
for drawing into the said engine the liquid to be impregnated, and the compressed
is so passed into the said engine as to meet the said liquid at a contracted part
in its interior and split it up into a kind of spray, or into globular particles, and
thoroughly intermingle with it, the said splitting up causing the liquid to quickly
absorb the necessary amount of gas with a proper distribution. The impregnated
liquid is then passed onto a receiver or contrivance for using it.

An impregnating engine or apparatus according to this invention is set forth
in the accompanying sheet of drawings, and its construction and also the process
of aeration will be described herein in connection therewith. In the said sheet
of drawings longitudinal sections of the said engine are shown in Figs. 1 and 2,
and cross sections, on the lines F and H, in Figs. 3 and 4. The difference between
Figs. 1 and 2 is only in respect of the positions of the moving parts, Fig. 1 showing
the liquid supply shut off from the delivery, and Fig. 2 open to the delivery.
The apparatus or engine is built up of a barrel casing a of metal, within which
is located the necessary parts and devices to constitute the impregnating mechanism..
This barrel casing is built up of three parts a², a³, a³, so as to admit of the interior
being opened for cleaning and for fitting; the connection of the said parts being
made by screwed portions a, af. The end a7 of this barrel casing is adapted to be
connected to a container or its equivalent, as it is the delivery end of the engine.
Centrally disposed and working within the bore c of the barrel casing, a, is a
circular rod or stalk, d, having a conical or taper head upon its one end, which
is nearest to the delivery end a of the engine, and upon its other a handle or
turn for rotating or turning the said rod or stalk. The middle part d' of the
said stalk is externally screwed for engagement with a like screwed box c² formed
in the bore of the middle part a³ of the barrel casing, and its handle end passes
through a packing gland fitted to the handle end of the engine's casing for
making and forming a gas-tight working bearing for the one end of the said stalk.
A small axial hole is bored through the rod or stalk from the nose end de of
the conical head for about half the length of the stalk and head combined, the
said axial hole leading from, or into, crossly directed passages or holes which
communicate with a surrounding chamber, 3, formed in the bore of the engine's
casing and connected by a branch supply g to a compressed bottle of carbonating
gas. The provision of this chamber is to enable the inlet cross holes, to the
stalk's axial hole de, to be at all times in communication with the gas supply g, no
matter whether the said stalk may be advanced or withdrawn for the purpose of
closing or opening the liquid supply. The conical head of the said stalk is
arranged to work upon a coned seating c disposed near to the delivery end of the
engine, (well forward of the gas inlet) and its nose end de, from whence issues the
compressed gas from the supply g, is arranged to protrude into the contracted
bore of the engine's casing near its delivery end. Inwards of the coned seat-
ing is formed a clearance chamber, c, into which the uncharged liquid from the
supply is directed at c, a non-return valve fitting h, which is in communication
with the water supply, being connected to the part c for the liquid's feed, and for
preventing the return of the liquid if the delivery end of the engine should be
stopped, or partly stopped, as would be the case if fitted to a soda water supply on
a large retailing premises.
It is the object of the conical head of the stalk and the seating, c, to control the
supply of the uncharged liquid to the delivery bore, wherein it meets the gas
issuing from the axial hole at the nose end and becomes split up into a fine
