An Improved Internal Stopper for Bottles or other Vessels
Containing Aerated Waters or Liquids
I, WILLIAM SAMSON, of 154 Seagate, Dundee, in the County of Forfar, Acrated
Water Manufacturer, do hereby declare the nature of this invention to be s
follows
-
This Invention, which relates to an improved stopper for bottles or other vessels
containing aerated waters or liquids, has for its object to produce a floating stopper
with its smaller end at all times situated upwards, so that the pressure of the gas in
the aerated water forces it up into the neck of the bottle or other vessel, to close the
said aperture
The stopper-which is an improvement upon my Patent No 14,755 1st December
AD 1885-18 fitted with a piece or pieces of metal, glass or other suitable material,
in such a manner that the stopper at all times floats on the liquid with its smaller end
or point upwards
The ballast may be inserted in the form of a ball, or it may be fixed on to the
bottom of the stopper
The stopper in its natural condition is necessarily larger than the aperture in the
neck of the vessel, and in order to get it thereinto it is placed in hot water or
otherwise made soft or compressed, and in that state is pushed into the bottle or
other vessel
The aperture in the neck of the vessel is made in two diameters, the larger of which
1s towards the inside, thus forming an annular seat
The stopper is made of cork, the point of same being in the form of a truncated
cone and the remaining portion cylindrical

I, WILLIAM SAMSON, of 154 Seagate, Dundee, in the County of Fortar, Aurated
Water Manufacturer, do hereby declare the nature of this invention and in whit
minner the sume is to be performed, to be particularly described and ascertained in
and by the following statement
-

cont uning acrated waters or liquids, his for its object to produce a floating stopper

DESCRIPTION OF DRAWINGS
In these drawings the same reference numerals are used to mark the same or like
parts, wherever they are repeated
Figs 12 and 3 are respectively a plan of upperside, an elevation and a vertical
section of one form of stopper constructed according to my present Invention
Fig 4 is in part an elevation and in part a vertical section of a bottle fitted with a
stopper constructed in accordance with my present Invention, the said stopper being
therein shewn as previous to the closing or sealing of such a bottle as hereinafter
explained
Fig 5 is a similar view of the same with the stopper in the position in which it 19
when the bottle is closed or sealed
The stoppers constructed according to my present Invention, and as represented
upon the annexed drawing, are formed partly conically, or as parts of cones, and
partly cylindrically, and my said invention has specially for its object so to construct
such stoppers that they shall float with their conical end upwards, on the surface of

page_text: the aerated water contained in the bottles to be stoppered To effect this balancing o
the stopper, a piece of material of greater specific gravity than that of the cork
stopper 1 is inserted or attached to its larger end This weight may consist, as shewn
at Figs 12 and 3 of the semispherical piece 2 of lignum vitae, porcelain or other
equivalent materia!
The beforementioned stopper, which it will be observed, is larger than the hole in
the neck 3 of the bottle 4 is immersed in hot water, or otherwise softened or
compressed, so as to enable it to be pushed into such bottle
When the bottles are charged with aerated liquid 5 the stoppers are forced into the
necks thereof, the openings through these necks being contracted so as to constitute a
seat in or against which the said stopper becomes wedged
I desire it to be understood that the necessary balancing of the hereinbefore
described stopper may be effected by weights of forms other than those shewn upon
the annexed drawings that arrangement being merely shewn as an example
Having now particularly described and ascertained the nature of my said
Invention and in what manner the same is to be performed, I declare that what
I claim is
-
The improved stopper 1 formed partly conically or as a part of a cone, and partly
cylindrically, the larger end of which is fitted with a weight of lignum vitae, or other
suitable material, so that the said stopper is caused to float always with its smaller end
upwards all substantially as and for the purposes herein before set forth with reference
to the annexed drawings
