page_text: LETTERS PATENT to Isaac Burdin of Station Glass Works, Knottingley, in
the County of York for an invention of IMPROVEMENTS IN INTERNAL STOPPERS
FOR BOTTLES TO CONTAIN AERATED WATERS AND OTHER LIQUIDS BOTTLED
UNDER PRESSURE
PROVISIONAL SPECIFICATION left by the said Isaac Burdin at the Office
of the Commissioners of Patents on the 27th April 1882.
"
ISAAC BURDIN of Station Glass Works, Knottingley in the County of York
IMPROVEMENTS IN INTERNAL STOPPERS FOR BOTTLES TO CONTAIN AERATED
WATERS AND OTHER LIQUIDS BOTTLED UNDER PRESSURE."
"
The Invention has for its object improvements in internal stoppers for bottles to
contain aerated waters and other liquids bottled under pressure and relates to an
improved construction of stopper whereby the necessity for employing a large
amount of force to open the bottle and thereby causing an explosion and in some
cases causing the bottle to break to the danger of the opener as is the case with
stoppers of the construction now in use.
According to my Invention I form on the exterior of the stopper preferably four,
five or six grooves but other number of grooves may be employed.
These grooves I form either lengthwise of the stopper or inclined around the
same.
By these means on slightly pressing the stopper it leaves the india rubber ring
surrounding the same and thus allows the pressure to escape through the grooves
and the stopper to fall into the bottle without causing either explosion or breakage
of the bottle

The Invention has for its object improvements in internal stoppers for bottles to
contain aerated waters and other liquids bottled under pressure and relates to an
improved construction of stopper whereby the necessity for employing a largo
amount of force to open the bottle and thereby causing an explosion and in some
cases causing the bottle to break to the danger of the opener as is the case with
stoppers-of-the-construction now_in_use is avoided.
According to my Invention I form. on the exterior of the stopper, four, five-or-
six grooves but other number of grooves may be employed.
These grooves I form either lengthwise of the stopper or inclined around the
same.
By these means on slightly pressing the stopper it leaves the india rubber ring
surrounding the same and thus allows the pressure to escape through the grooves
and the stopper to fall into the bottle without causing either explosion or breakage
of the bottle.
-And-in-order that my said Invention may be more clearly understood and readily
DESCRIPTION OF THE DRAWINGS.
Figures 1 and 2 are longitudinal sections of the upper parts of a bottle with my
improved stopper therein Figure 1 shewing the bottle completely closed and
Figure 2 showing the body of the stopper slightly depressed and thereby giving
vent to the gas before the bottle is completely unstopped. Figure 3 is a sido
elevation, Figure 4 is a longitudinal section and Figure 5 is a cross section of the
body of the stopper separately. a is the body of the stopper which is as heretofore
formed with a circular chase or groove a', around the same to receive the ring 6 of
india rubber, c is the neck of the bottle in the interior of which is formed a seat c¹
for the india rubber ring b against which the latter is pressed by the pressure
within the bottle acting upon the stopper.
The stopper and its mode of action as above described form no part of my present
invention which consists in forming on the exterior of the body a of the stopper
any required number of grooves a² for the purpose berein after described. In the
drawings I have represented the body a of the stopper provided with two of such
grooves a² which number I have found sufficient for the purposes of my Invention
but if desired other numbers of such grooves may be employed and although I have
represented such grooves as being formed lengthwise of the stopper they may be
formed inclined around the same.
By the use of stoppers constructed with grooves a² as above described I am
enabled to open the bottle without the necessity for employing a large amount of
force thereby preventing an explosion on opening the bottle and the possible
breakage of the bottle to the danger of the opener as is sometimes the case with
bottles supplied with stoppers of the construction heretofore employed.
By the aid of my Invention, on slightly pressing the stopper a, it leaves the
india rubber ring 6 surrounding the same and thus allows the pressure to escape

either explosion or breakage of the bottle.
Having thus described the nature of my said Invention and the mode in which
I carry the same into effect, I would have it understood that what I claim is
3 constructing internal stoppers with grooves a substantially as herein shewn
and described and for the pupose stated.
In Witness whereof I the said Isaac Burdin have hereunto set my hand
and seal this twenty fourth day of October in the year of our Lord one
thousand eight hundred and eighty two.
