Year: 1875

page_text: LETTERS PATENT to Hector Aylesbury, of the City and County of
Gloucester, for the Invention of "IMPROVEMENTS IN STOPPERS FOR BOTTLES
FOR CONTAINING AERATED AND OTHER LIQUIDS.""
Sealed the 13th July 1875, and dated the 23rd January 1875.
PROVISIONAL SPECIFICATION left by the said Hector Aylesbury at the
Office of the Commissioners of Patents, with his Petition, on the
23rd January 1875.
I, HECTOR AYLESBURY, of the City and County of Gloucester, do
hereby declare the nature of the said Invention for "IMPROVEMENTS IN
STOPPERS FOR BOTTLES FOR CONTAINING AËRATED AND OTHER LIQUIDS," to be
as follows:-
This Invention consists in the construction and employment of
stoppers for bottles consisting of a disc fixed to a rod, and of another
disc which can be caused to slide on rod, or in other words through
which the rod slides when required.
The object of the first disc is to stopper the bottle, and for that pur-
pose to be caused to come against the root of the neck thereof. The

page_text: chief object of the second is to prevent dirt or anything else from getting
into the neck of bottle. The top disc may be made with flange to
cover neck, or without same, when it can enter the neck as preferred.
The rod has button at top.
'
To use stopper I place same into neck, which is easily done because
the discs contract, being preferably made of india-rubber or a com-
position thereof prepared in such way as not to injure the liquid in
bottle.
The bottle is filled with acrated liquid in ordinary way, whether the
bottle is inverted or not, and the gas forces the lower disc against root
of neck, while the top disc is left just inside neck and stops the mouth
thereof, thereby preventing dirt getting in. For further security the
lower disc may be further pulled against the root of neck by the
rod.
To unstopper the bottle, force down the rod through top disc, which
simultaneously drives down the lower disc, air is admitted and the
liquid flows out; while partially inverting the bottle to pour out the
liquid place the finger on the rod or upper disc, which causes the said
rod and both dises to be set at an angle with the neck and there is free
egress for the liquid.
To clean the bottle the stopper can be forced into same and the
owlingwy alconing hruch intenduend and wlion again filled the son forces

SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Hector Aylesbury in the Great Scal Patent Office 2
on the 23rd July 1875.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, HECTOR
AYLESBURY, of the City and County of Gloucester, send greeting..
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-third day of January, in the year 3
of our Lord One thousand eight hundred and seventy-five, in the thirty-
eighth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said Hector Aylesbury, Her special licence,

page_text: that I, the said Hector Aylesbury, my executors, administrators, and
assigns, or such others as I, the said Hector Aylesbury, my executors,
administrators, and assigns, should at any time agree with, and no
others, from time to time and at all times thereafter during the term
therein expressed, should and lawfully might make, use, exercise, and
vend, within the United Kingdom of Great Britain and Ireland, the
Channel Islands, and Isle of Man, an Invention for "IMPROVEMENTS
IN STOPPERS FOR BOTTLES FOR CONTAINING AËRATED AND OTHER LIQUIDS,"
upon the condition (amongst others) that I, the said Hector Aylesbury,
my executors or administrators, by an instrument in writing under
my, or their, or one of their hands and scals, should particularly
describe and ascertain the nature of the said Invention, and in
what manner the same was to be performed, and cause the same
to be filed in the Great Seal Patent Office within six calendar
months next and immediately after the date of the said Letters
Patent.
NOW KNOW YE, that I, the said Hector Aylesbury, 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, reference being had to the accompanying
Drawings, and to the letters of reference marked thereon, that is to
say :-
My said Invention, which relates to the construction and employment
of improved stoppers for bottles, consists of two discs of india-rubber
(or a composition thereof) situate upon a rod or spindle, to one extremity
of which one of the said discs is fixed by a nut and washer or other
suitable means, while the other disc is capable of a sliding movement
upon the rod or spindle. When in its position in the bottle the
periphery of the lower and fixed disc is in contact with the root of the
bottle neck, the stopper being held there by the pressure of gas within
the bottle, the upper disc serving as a protection against the ingress of
dust or insects to the bottle ucck. The said upper disc may also be
provided with a flanch or lip, which rests upon the top of the bottle
neck and more effectually closes it, but it is preferred for general use to
employ the form of disc first described.
The upper end of the rod or spindle is provided with a button or
metallic disc, upon which the finger is laid when it is desired to pour

page_text: out a part or the whole of the contents of the bottle; this is effected.
by depressing the rod or spindle, and consequently the lower disc.
The gas in escaping blows the upper disc out of the bottle neck and
leaves it open for the passage of the liquid.
And in order that my said Invention may be properly understood, I
now proceed more particularly to describe and set forth the system,
mode, or manner in or under which the same is or may be used or
carried practically into effect, reference being had to the annexed
Sheet of Drawings and to the letters and figures marked thereon,
similar parts in the different views being simarly lettered, that is to
say :-
Fig. 1 on the annexed Sheet of Drawings shews an acrated water
bottle in vertical section, to which my improved stopper is shown applied;
Fig. 2 is a vertical section of the stopper; while Fig. 3 is a perspective
view or elevation of the same.
As shewn by these Figures the stopper consists of two india-rubber or
composition discs, the lower A of which is fixed to the lower extremity
of the rod or spindle B by means of the nuts C and D, as more par-
ticularly illustrated at the sectional view, Fig. 2.
free to slide upwards and downwards upon the rod or spindle B which
is also provided at its upper part with a smaller metallic disc or
button F.
The upper disc E is
When the stopper is in use, that is to say, when it occupies the
position in the bottle shown at Fig. 1, the lower disc A. is held against
the root of the neck by the 'gaseous pressure within the bottle, thereby
preventing the escape of gas or liquid therefrom; and the upper disc E
occupying the position shewn closes the bottle neck and prevents the
ingress of dust, insects, or other extraneous matter. The disc E, which
may be made of rubber or metal, or both combined (as shewn at Fig. 5),
or other suitable materials, may also have a flanch or lip to cover the top
of the bottle neck, as shown at Fig. 4, whereby the neck is more effec-
tually closed and the disc E preserved at its proper level.
When it is desired to pour out the whole or a portion of the contents
of a bottle, the rod or spindle B and disc A are depressed by pressure
from the finger of the operator applied to the button or disc F, where-
upon the gas escapes, blowing the disc E out of the bottle neck and
leaving it free for the passage of the liquid; whilst the bottle is being

page_text: emptied and is inverted, as shewn at Fig. 5, the stopper is held by the
finger in such a position as not to interfere with the efflux of liquid from
the bottle, the external or exposed part of the stopper being held above
and clear of the outflowing liquid.
If it is not desired to use the whole of the contents at once the bottle
may be re-stoppered by pulling the disc A against the root of the bottle
neck, when the gaseous pressure remaining in the bottle will hold it
there until again depressed by the finger, as herein-before described.
Having now described my said Invention, the construction of the
same, and mode of application, I would observe in conclusion, that what
I claim as the Invention secured to me by the herein-before in part
recited Letters Patent is, the employment of a stopper for stopping
bottles containing aerated waters or other liquids, constructed and
operated substantially in the manner herein-before described and shewn,
or any mere modification thereof.
In witness whereof, I, the said Hector Aylesbury, have hereunto
set my hand and seal, this Twentieth day of July, in the year of
our Lord One thousand eight hundred and seventy-five.
