Year: 1880

page_text: LETTERS PATENT to Louis Emile Chagniat, of Wheatsheaf Lane, South
Lambeth Road, in the County of Surrey, Glass Manufacturer, for an Invention
of "IMPROVEMENTS IN CLOSING OR STOPPING BOTTLES, JARS, AND OTHER
VESSELS MADE OF GLASS OR VITREOUS MATERIALS."
PROVISIONAL SPECIFICATION left by the said Louis Emile Chagniat at
the Office of the Commissioners of Patents on the 22nd March 1880.
LOUIS EMILE CHAGNIAT, of Wheatsheaf Lane, South Lambeth Road, in the
County of Surrey, Glass Manufacturer. "IMPROVEMENTS IN CLOSING OR STOPPING
BOTTLES, JARS, AND OTHER VESSELS MADE OF GLASS OR VITREOUS MATERIALS."
My Invention consists in placing upon the neck of a glass bottle or other vessel
on the exterior, a ring of metal having a screw thread to receive a screwtbreaded
cap, this screwthreaded ring being so secured on the neck of the bottle that it may
be said to form one piece with it.
Having obtained my screwthreaded ring or collar by stamping, or in any
ordinary manner, I propose to fit it upon the neck of the bottle either during
manufacture or by bringing it to such a heat that the glass of which it is made will
enter into the channels formed by the screwthread, and cause the ring to adhero to
the neck as if it were a part thereof.
The metal cap by which the mouth of the bottle is to be closed having also been
stamped out or otherwise made, and screwthreaded or tapped,
to place
propose
therein a layer or cushion of cork or other clastic material, so that when this cap is
scrowed down on to the mouth of the bottle, the edges of the mouth or rim will
enter into the cork and ensure an hermetical closing.
This mode of closing or stoppering may be used with the automatic ball stopper
in bottling effervescing liquids, but the screw cap will of itself prove a good
stoppering for such liquids.
It will be understood that my metallic screwthreaded stoppering may be applied
not only to glass bottles, but to a variety of vessels made of any vitreous material,
and for any purpose for which it may be found suitable.

It will bo understood that my metallic screw threaded stoppering may be applied
not only to pocket flasks, as shown on the Drawing, but to glass bottles of every
shape and size, and to jars and a variety of vessels made of vitreous material, and
for any purpose for which my Invention may be found suitable.
My Invention permits the use of a very thin metal for the collar and cap, which
advantage added to the facility of applying my stoppering makes its use very
economical.
Having now described and ascertained the nature of my said Invention, and in
what manner it is or may be performed, what
I claim as of my Invention and as secured to me by the herein before in part
recited Letters Patent is,-
Firstly. The application of the ring or collar during the manufacture of the glass
bottle or vessel made of glass or vitreous material so that it forms part thereof,
substantially as specified.
Secondly. The application of the ring or collar to the bottle or other vessel

page_text: by reheating and partially fusing that part of the neck of the bottle or other
vessel upon which it is to be secured, substantially as above set forth.
In witness whereof, I, the said Louis Emile Chagniat, have hereunto set my
hand and seal, this Thirty first day of August, in the year of our Lord
One thousand eight hundred and eighty.
Signed, sealed, and delivered, by
the within named Louis Emile
Chngniat, in the presence of
