Year: 1872

page_text: LETTERS PATENT to Jean Louis de Negroni, of No. 2, Boulevard du
Temple, Paris, in the Republic of France, Gentleman, for the
Invention of "IMPROVEMENTS IN STOPPERING BOTTLES AND OTHER
VESSELS."
PROVISIONAL SPECIFICATION left by the said Jean Louis de Negroni
at the Office of the Commissioners of Patents, with his Petition, on
the 23rd July 1872.
I, JEAN LOUIS DE NEGRONI, of No. 2, Boulevard du Temple, Paris,
in the Republic of France, Gentleman, do hereby declare the nature of
the said Invention for "IMPROVEMENTS IN STOPPERING BOTTLES AND OTHER
VESSELS," to be as follows, that is to say :-
-
The Invention consists in an improved arrangement or construction of
stopper for bottles and other vessels.
I employ a plate turning round an axis, and uncovering or covering
the whole or part of the opening of the bottle or vessel to be stoppered.
This plate may be placed at the upper part of its axis, and may be

page_text: provided on its top with a knob. It is lined with cork or other com-
pressible and elastic material to effect an air-tight closing. It may be
placed directly above the opening of the bottle or other vessel to be
closed, and bear frictionwise thereon, with or without the medium of
cork. I can place it so as to cause it to slide between two pieces of cork
or other suitable material.
The stopper may form part of the bottle or vessel to be closed, and be
made of metal, glass, earthenware, or china ware, or it may be applied
thereto so as to move on it with gentle friction by means of solder,
mastic, or other cement.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Jean Louis de Negroni in the Great Seal Patent
Office on the 22nd January 1873.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JEAN
LOUIS DE NEGRONI, of No. 2, Boulevard du Temple, Paris, in the
Republic of France, Gentleman, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-third day of July, in the year of
our Lord One thousand eight hundred and seventy-two, in the thirty-sixth
year of Her reign, did, for Herself, Her heirs and successors, give and
grant unto me, the said Jean Louis de Negroni, Her special licence
that I, the said Jean Louis de Negroni, my executors, administrators,
and assigns, or such others as I, the said Jean Louis de Negroni, 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 STOPPERING BOTTLES AND OTHER VESSELS," upon the condition (amongst
others) that I, the said Jean Louis de Negroni, 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

page_text: within six calendar months next and immediately after the date of the
said Letters Patent.
NOW KNOW YE, that I, the said Jean Louis de Negroni, 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 Drawing hereto
annexed, and to the figures and letters marked thereon, that is to
say:
-
The Invention consists in an improved arrangement or construction of
stopper for bottles and other vessels.
To make the construction of the improved stopper better understood,
I will proceed to describe the same by reference to the accompanying
Drawing, in which Figures 1 and 2 represent a glass, earthenware, or
metal bottle or flask, the neck of which is formed so as to receive the
improved stopper, as shewn in Figures 4 and 5.
This improved stopper consists of a plate 6 moved by the knob d, and
covered with cork or other analogous elastic material a, and which by
pivotting on the pin e opens or closes the bottle.
Figure 5 shews the bottle closed, and Figure 6 shews it open.
Figures 7, 8, and 9 represent another mode of constructing the im-
proved stopper. D is a central opening; E, a pin round which turns a
metallic plate C, F, moving over a fixed piece of cork G, and effecting
the closing.
The whole forms a capsule, shewn open in Figure 9, and closed at
Figures 7 and 8. This construction of stopper is applicable to all kinds
of bottles, flasks, and other like vessels.
Figures 10 and 11 represent a stopper which can be fixed by means of
a perforated cork L, L', over the opening of any kind of bottle or other
like vessel, as shewn in Figure 11. The opening may be opened or
closed by the plate C, D, moving over a piece of cork G, applied as
shewn in Figure 8. N, N', is a neck for pouring out the contents.
Figures 12 and 13 represent a stopper which can be introduced into
and on a bottle, as herein-before described. In this case the plate G
covered with cork is turned by means of a knob A entirely round the
axis I, as seen in Figure 13, which shews a plan of the capsule.

page_text: uncovered. The closing is effected by means of a spring, which in the
rotatory motion of the plate comes under the packing m.
In Figure 14 is shewn the piece or plate of cork G having an open
part and a solid part G³, which may or may not correspond with an
opening I underneath. In the position shewn by the Drawing the bottle
is closed. By turning round the knob A the cork G is moved into the
position; G¹ uncovers the opening I, and the liquid can be poured out
through the spout H, Figure 15.
The arrangement shewn by Figure 16 is similar to that in Figure 4,
but in this case the opening in the plate covered with cork is very small, 1
as shown in plan, Figure 17, so that a slight movement of rotation only
is required to effect the closing.
Figures 18 and 19 shew the capsule, which may be opened or closed
as in Figure 8, with this difference, that two layers of cork are placed
one above, and the other underneath the plate in order to effect a tight 1
closing.
These improved stoppers are applicable to all kinds of bottles, flasks,
and like vessels containing solid, liquid, or gaseous substances.
In witness whereof, I, the said Jean Louis de Negroni, have hereto
set my hand and scal, this Twentieth day of January, in the 2
year of our Lord One thousand eight hundred and seventy-
three.
