IMPROVEMENTS IN CLOSING OR STOPPERING BOTTLES, JABS, AND OTHER LIKE VESSELS
Year: 1856

page_text: LETTERS PATENT to Jean Alexandre Labat, j', of Bordeaux, in the
Empire of France, and of 32, Essex Street, Strand, London, for the
Invention of "IMPROVEMENTS IN CLOSING OR STOPPERING BOTTLES, JABS, AND
OTHER LIKE VESSELS."
Sealed the 20th February 1857, and dated the 10th October 1856.
PROVISIONAL SPECIFICATION left by the said Jean Alexandre Labat,
at the Office of the Commissioners of Patents, with his Petition, on the
10th October 1856.
I, JEAN ALEXANDRE LABAT, j', of Bordeaux, in the Empire of France, and
of 32, Essex Street, Strand, London, do hereby declare the nature of the said
Invention for "IMPROVEMENTS IN CLOSING OR STOPPERING BOTTLES, JARS, AND OTHER
LIKE VESSELS."
This Invention relates to certain improvements on my Patent of Sept 28th,
1853, No. 2227, for improvements in stoppering bottles, jars, and other vessels,
and consists in fixing the threaded-metal collar therein described to the neck
of the bottle or other vessel. For this purpose I prefer to cast the metal
collar by a suitable mould around the neck of the bottle or other vessel, which
is provided with grooves or other indentations to recieve the liquid metal.
When the bottle or other vessel is removed from the mould, and the metal
becomes set, the threaded collar is ready to receive the screw capsule described
in my former Patent, by which the bottle or other vessel becomes hermetically
closed in a simple and efficient manner.

page_text: SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Jean Alexandre Labat, in the Great Seal Patent Office on
the 8th April 1857,
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JEAN
ALEXANDRE LABAT, jr, of Bordeaux, in the Empire of France, and of 32, Essex
Street, Strand, London, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Tenth day of October, in the year of our Lord
One thousand eight hundred and fifty-six, in the twentieth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the said
Jean Alexandre Labat, jr, Her special licence that I, the said Jean Alexandre
Labat, j', my executors, administrators, and assigns, or such others as I, tho
said Jean Alexandre Labat, j', 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 CLOSING OR STOPPERING BOTTLES, JARS, AND OTHER LIKE
VESSELS," upon the condition (amongst others) that I, the said Jean Alexandre
Labat, j', my executors or administrators, by an instrument in writing under
my, or their; or one of their hands and seals, 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 Jean Alexandre Labat, j', do hereby
declare the nature of the said 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 to improvements made on a Patent granted to me on
the 28th day of September 1853 for an improved system of closing or
stoppering bottles, jars, and other like vessels, and consists chiefly in making
the metal screw-threaded collar therein described fixed on the neck of the
bottle or other vessel instead of being moveable; and this I effect by casting
the metal collar on the neck of the bottle or other vessel.
In the annexed Drawings, Figures 1 & 2 represent the necks of two bottles,
one provided with a groove on the outside; the other has notches or inden-
tations. The object of the groove or notches being to receive the metal collar

page_text: and retain it. In carrying this Invention into practice, I prefer to use the
notches or indentations rather than the grooved system, as the metal during
the operation of casting enters the notches and act as rivets.
Fig. 3 represents a bottle neck in the mould ready to have the collar cast
thereon.
Figs. 4 & 5 represent two necks of bottles with the collar, the first on the
grooved system, the other on the notched system; and Figures 6 are the
capsules ready to be screwed on.
Figures 7, 8, 9, represent the kind of mould I use in casting the screw-
threaded collars on the necks of the bottles; the liquid metal enters by the
ducts or channels 10, 10.
The capsules or stoppers may be punched out and afterwards be supplied
with the screw thread, or they may be cast complete in one operation. I
prefer the latter method, and for that purpose I use a mould, such as repre-
sented by Figures 11, 12, 13, 14, & 15. The two projections on the top of
the capsule for screwing it tightly on the bottle being cast at the same time,
as shown by dotted lines, Fig. 15.
Having now described the nature of my Invention, and the manner in
which it may be carried into effect, what I wish to claim and secure by the
herein in part recited Letters Patent is, the construction and application of
fixed screw-threaded collars and capsules or stoppers to screw thereon, for
closing bottles, jars, and other like vessels, as herein set forth.
In witness whereof, I, the said Jean Alexandre Labat, jr, have hereunto
set my hand and seal, this Sixth day of April, in the year of our Lord
One thousand eight hundred and fifty-seven.
LABAT, J. (L.S.)
