PROVISIONAL SPECIFICATION.
A New Air-tight Stopper for Bottles and Jars.
I, SAMUEL MARKS of No. 68 High Street, Deptford, in the County of Kent,
Manufacturing Jeweller, do hereby declare the nature of this invention to be as
follows:-
It has been found difficult to produce an air-tight stopper that can be adapted
from one bottle or jar to another, at any and at all times, when an accident or
occasion occurs.
My invention consists of making an air-tight stopper for bottles and jars which
is capable of being fitted over and over again to other bottles and jars, should the
first or original vessel, to which it had been attached, become broken.
I prefer to make the air-tight stopper of iron or brass, but it can be made of
other metals, and plated or otherwise, to be fixed round the neck of the bottle
or jar.
The part of the stopper that fits inside the mouth of the jar or bottle, to render
it completely air-tight, is made of india-rubber and brass, and can be easily opened
and closed by hand owing to its being governed in its action by a small lever or by
leverage.
To describe more fully this my invention the stopper is made to fit in this way:
A metal band is fixed round the top of the bottle or jar, and is fastened by a screw,
and it can thus be easily taken off and fixed on another bottle or jar when an
accident or occasion arises and an india-rubber stopper is fitted in the mouth of
the bottle or jar which completely shuts out the air from the same and which is
opened or closed at will by a small lever, which works or acts from the metal band
round the neck of the bottle or jar.
In the event of the jar having no groove or collar round the top of it, I make a
wire frame to fit round the bottom of it, and thus make a connection with the top
so as to make the vessel perfectly air-tight in this way.
Dated this First day of February 1893.
COMPLETE SPECIFICATION.
A New Air-tight Stopper for Bottles and Jars.
I, SAMUEL MARKS of No. 68 High Street, Deptford, in the County of Kent,
Manufacturing Jeweller, do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement :-
It has been found difficult to produce an air-tight stopper that can be adapted
from one bottle or jar to another, at any and at all times, when an accident or
occasion occurs.
My invention consists of making an air-tight stopper for bottles and jars which
is capable of being fitted over and over again to other bottles and jars, should the
first or original vessel, to which it had been attached, become broken.
I prefer to make the air-tight stopper of iron or brass, but it can be made of
other metals, and plated or otherwise, to be fixed round the neck of the bottle
or jar.
The part of the stopper that fits inside the mouth of the jar or bottle, to render
it completely air-tight, is made of india-rubber or cork and brass, and can be easily

page_text: opened and closed by hand owing to its being governed in its action by a small lever
or by leverage.
To describe more fully this my invention, the stopper is made to fit in this
manner A metal collar or band is fixed round the neck or top of the bottle or
jar, and is fastened by a screw which can be unscrewed at any time, consequently it
can thus be easily taken off and fixed on another bottle or jar when an accident or
occasion arises; and an indiarubber or cork, or an indiarubber and cork stopper is
fitted in the mouth of the bottle or jar (which completely shuts out the atmospheric
air from the same) and which is opened and closed at will by a small lever, which
works or acts from the metal band fixed round the neck of the bottle or jar.
In the drawings annexed, the part marked A is the bottle or vessel, which may
be of glass or earthenware. The part marked B is a metal collar or band which is
fitted round the top of the neck and under the lip or in the groove of the bottle or
vessel, and is fixed or fastened by a screw 6 Fig. 2 through two holes in the band
perforated and threaded, which can be unscrewed when required, and fixed on
another similar vessel. To this metal collar or band is fixed the metal top marked C
under the circular plate of which is a round fixed pad marked d made of india-
rubber or cork or of layers of indiarubber and cork, and forms the air-stopper
which by the pressure given by the lever markede (which is also pivoted to the
band or collar marked B) being brought down is firmly pressed into the mouth of
the bottle or vessel, thus effectually excluding the atmospheric air, and rendering
the bottle or vessel perfectly air-tight. To open the bottle or vessel the lever
marked e is simply lifted upwards, and the stopper then falls clear of the mouth of
the bottle so that the contents of the same may be emptied partly or wholly without
any obstruction.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is:
1. The construction and use of a stopper for bottles and jars which are made
perfectly air-tight by a lever or by leverage given to the stopper substantially as
described.
2. The construction and use of an air-tight stopper made of metal and india-
rubber or cork or of india-rubber and cork substantially as described.
