the Commissioners of Patents, with his Petition, on the 8th May
1873.
I, EUGENE GERAUT, of Farringdon Road, in the City of London, do
hereby declare the nature of the said Invention for "IMPROVEMENTS IN
AERATED WATER BOTTLES, AND STOPPERS FOR THE SAME," to be as follows:→
My Invention has for its object improved methods of constructing
the necks of bottles in which soda water, lemonade, or other aërated.
liquids are contained, so that stoppers can be readily and firmly fixed in
them without liability to injury.
Also of improved methods of constructing stoppers to fit such bottle.
necks, through which stoppers the bottles can be filled with the aërated
liquids, or the latter can be discharged as required.
For the purpose of my Invention I form a hollow screw inside the
neck of the bottle, into which the stopper (which has a corresponding
screw formed upon it) can be screwed. I make this screw of metal by
casting it in a fluid state into the neck of the bottle (into which
a suitable mould may be first introduced in order to limit the flow of

page_text: the metal), and I form one or more recesses on the inside of the neck
of the bottlo, into which recesses the metal flows so as to form (when
cool) projections, which prevent the metallic screw from being blown
out.
Sometimes for the same purpose I form the mouth of the bottle with
a lip overhanging inwards, inside which the metal screw is cast.
I do not make the ring reach quite to the mouth of the bottle, but
I make it end at a distance sufficiently within the latter to form a
recess formed by the glass mouth of the bottle outside the ring. By
this method of construction great advantages are obtained in economy
of material and cheapness of manufacture as compared with bottles
having external screws and caps made in the ordinary methods well
understood and practised..
The improved stopper, which I make fit the neck of the bottle, fitted
with a metallic screw ring as above described, is constructed as
follows:-
I take a metallic screw, fitting into the screw in the bottle neck, and
having a collar upon it at a sufficient distance from its lower end.
Below this collar, upon the screw, I place a ring of india-rubber or
other suitable elastic material of such size that when the stopper is
screwed into the neck of the bottle the ring is compressed into the
recess formed by the top of the hollow metal screw and the glass mouth
of the bottle as above described, and a perfectly tight joint is thus
made. :
The stopper is made hollow or tubular, and its lower part contains a
valve which may be of the ordinary kind, and is pressed upwards against
a seat which is formed in the hollow or tubular part of the stopper.
This seat is made preferably in the usual way with an angular edge
pointing downwards, the upper part of the valve having a recess into
which is fitted a piece of india-rubber or other soft substance, which,
when pressed against the valve seat, makes a perfectly tight joint. The
valve is forced upwards by the pressure of the gas in the bottle, and by
a spiral spring which is contained in the upper tubular part of the
stopper, and through which spring a central wire passes, the lower end
of which is screwed into the valve, and the upper end is attached to a
button or knob, the stem of which fits the top of the stopper, and is
pressed up by the spiral spring. This stem may have one or more

page_text: feathers formed upon it, fitting into corresponding grooves in the stopper
to prevent the stem from turning round. A discharge pipe, straight or
curved, is formed passing from the tubular stopper above the valve.
When the mouth of the bottle is turned down and the button or knob
is pressed, the valve is opened and the aërated liquid is discharged. On
releasing the button the valve is returned to its seat by the pressure of
the gas and of the spring, and any quantity of the aërated liquid can
thus be drawn off from time to time as required.
The stopper may have a tube attached to it, passing nearly to the
bottom of the bottle, and the discharge pipe may be turned downwards
so that the aërated liquid may be discharged without inverting the
bottle.
In order to fill with aërated liquid the bottles fitted with my improved
apparatus as described, they are placed in a suitable frame, by which the
discharge pipe described is held in close and firm contact with a supply
pipe, into which the aërated liquid is then admitted under pressure. The
valve in the stopper is then opened by means of the button or knob,
and the bottle thus becomes filled with the liquid..
The accompanying Drawing is in illustration of my Invention.
a is an aërated water bottle, into the neck of which, b, is cast the
metallic screw c, which is prevented from being forced from the bottle
by the projection d. The stopper is formed with a screw c, and is fitted
with the india-rubber ring f, which is compressed into the recess formed
by the end of the screw c, and the glass sides of the mouth of the
bottle. is the discharge pipe, and i is a button or knob, which, when
pressed (the bottle being inverted) opens the valve and allows the
escape of the aërated liquid.
