AN IMPROVEMENT OR IMPROVEMENTS IN THE MANUFACTURE OF STOPPERS FOR BOTTLES FOR CONTAINING AËRATED OR GASEOUS LIQUIDS
Year: 1877

page_text: LETTERS PATENT to Lauchlan Rose, of 11, Curtain Road, Finsbury, in the
County of Middlesex, Lime Juice Merchant, for the Invention of " AN
IMPROVEMENT OR IMPROVEMENTS IN THE MANUFACTURE OF STOPPERS FOR
BOTTLES FOR CONTAINING AËRATED OR GASEOUS LIQUIDS."
Sealed the 5th February 1878, and dated the 31st October 1877.
PROVISIONAL SPECIFICATION left by the said Lauchlan Rose at the
Office of the Commissioners of Patents on the 31st October 1877.
LAUCHLAN ROSE, of 11, Curtain Road, Finsbury, in the County of Middlesex,
Lime Juice Merchant. "AN IMPROVEMENT OR IMPROVEMENTS IN THE MANUFAC-
TURE OF STOPPERS FOR BOTTLES FOR CONTAINING AËRATED OR GASEOUS
LIQUIDS."
This Invention consists in improvements in the manufacture of that class of
stoppers described in the Specification of former Letters Patent granted to me, and
dated the Ninth day of March, One thousand eight hundred and seventy-seven,
No. 960, the main object of the present improvements being to manufacture such
stoppers, having the body of greater specific gravity than the bottom, in one
operation, instead of it being necessary to form such stoppers of two or more parts
requiring afterwards to be adjusted together.
In constructing stoppers of vulcanite and xylonite or other suitable moulding
material, I produce the stoppers from moulds, the body or upper portion of the
stopper being moulded in vulcanite, xylonite, or other material, so prepared
that it shall have a specific gravity much greater than the vulcanite, xylonite,
or other material used for forming the lower portion of the stopper, both materials
being united from the pressure exercised in the moulding process.
I am thus enabled to produce a stopper in one piece, having the body or head
portion of greater specific gravity than the bottom, and thus securing a proper

page_text: gravitating stopper for the purpose described in a more simple and economical
manner than hitherto.
It will be understood that where the material employed for the body of the
stopper is of light specific gravity, its gravity may be increased by introducing a
weight of suitable material in the interior of the body portion of the mould.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said Lauchlan Rose in the Great Seal Patent Office on the 29th April
1878.
LAUCHLAN ROSE, of 11, Curtain Road, Finsbury, in the County of Middlesex,
Lime Juice Merchant. "AN IMPROVEMENT OR IMPROVEMENTS IN THE MANU-
FACTURE OF STOPPERS FOR BOTTLES FOR CONTAINING AËRATED OR GASEOUS
LIQUIDS."
This Invention consists in improvements in the manufacture of that class of
stoppers described in the Specification of former Letters Patent granted to me, and
dated the Ninth day of March, One thousand eight hundred and seventy-seven,
No. 960, the main object of the present improvements being to manufacture such
stoppers, having the body of greater specific gravity than the bottom, in one
operation, instead of it being necessary to form such stoppers of two or more parts
requiring afterwards to be adjusted together.
În constructing stoppers of vulcanite and xylonite or other suitable moulding
material, I produce the stoppers from moulds, the body or upper portion of the
stopper being moulded in vulcanite, xylonite, or other material so prepared that is
shall have a specific gravity much greater than the vulcanite, xylonite, or other
material used for forming the lower portion of the stopper, both materials being
united from the pressure exercised in the moulding process.
I am thus enabled to produce a stopper in one piece, having the body or head
portion of greater specific gravity than the bottom, and thus securing a proper gravi-
tating stopper for the purpose described in a more simple and economical manner
than hitherto.
Where the material employed for the body of the stopper is of light specific
gravity, its gravity may be increased by introducing a weight of suitable material
in the interior of the body portion of the mould during the process of moulding.
But to make my Invention better understood I will now proceed to describe the
same by reference to the accompanying Drawing in which,

Figure 1 is a section of a stopper moulded in one operation from two materials of
different specific gravity; Figure 2, elevation of the same; and Figure 3, elevation
of same, shewing the usual washer applied thereto.
Figures 4 and 5 are sections of stoppers formed by moulding them from suitable
material and having a weight introduced into the interior of the body during the
moulding operation; Figures 6 and 7, elevations of same; and Figures 8 and 9,
elevations of same with washer applied.

page_text: In Figure 1, a is the body or upper portion of the stopper, of greater specific
gravity than the lower portion b, the two materials being united by the moulding
process; c, groove for the ordinary india-rubber washer d, shewn applied in
Figure 3.
In Figures 4 and 5, e shews the weight of lead introduced into the body portion
of the mould during the process of moulding, so as to increase the gravity of the
head of the stopper; b, lower portion of the stopper; c, groove for the usual washer
d, shewn applied in Figures 8 and 9.
I would here observe that vulcanite and xylonite are materials especially adapted
for making stoppers according to my Invention.
Having thus described my Invention, and the best means with which I am
acquainted for carrying the same into effect, I wish it to be understood that what
I claim is,-
Firstly. The manufacture of stoppers for bottles for containing aërated or gaseous
liquids by moulding them in one operation from two materials of different specific
gravity, as and for the purpose herein-before described.
Secondly. The manufacture of stoppers for bottles for containing aërated or gaseous
liquids, by moulding them with a weight in the body portion of the stopper, as and
for the purposes herein-before described.
In witness whereof, I, the said Lauchlan Rose, have hereunto set my hand
and seal, this Twenty-ninth day of April, in the year of our Lord One
thousand eight hundred and seventy-eight.
Witness,
