near Bradford, in the County of York, for the Invention of "IMPROVE-
MENTS IN STOPPERS FOR BOTTLES OR OTHER SIMILAR ARTICLES AND IN THE
METHOD OF AND MEANS FOR SECURING THE SAME."
Sealed the 14th October 1876, and dated the 28th April 1876.
PROVISIONAL SPECIFICATION left by the said Stephen Walker at the
Office of the Commissioners of Patents on the 28th April 1876.
STEPHEN WALKER, Aërated Water Manufacturer, of Shipley, near Bradford, in the
County of York. "IMPROVEMENTS IN STOPPERS FOR BOTTLES OR OTHER SIMILAR
ARTICLES, AND IN THE METHOD OF AND MEANS FOR SECURING THE SAME."
My Invention relates to employing a tapered screwed stopper, which being turned
in an india-rubber washer placed in the neck of the bottle, firmly secures the
stopper in the bottle or other similar article. For this purpose the neck of the
bottle or other similar article is made with a recess in the top part, which is forned
rather long to allow of fitting in it a thick india-rubber washer; in this washer is
turned a tapered stopper made with a coarse screw; the india-rubber washer presses
into the hollow parts of the screw, firmly securing the stopper in the neck of the
bottle. The top of the stopper is made square, six or eight sided, or of any other
suitable form; and by unscrewing the stopper the screw is released from the
india-rubber washer and the stopper is easily removed.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed
by the said Stephen Walker in the Great Seal Patent Office on the 17th
October 1876.

STEPHEN WALKER, Aërated Water Manufacturer, of Shipley, near Bradford, in the
County of York. IMPROVEMENTS IN STOPPERS FOR BOTTLES OR OTHER SIMILAR
ARTICLES, AND IN THE METHOD OF AND MEANS FOR SECURING THE SAME.
The said Invention relates to employing a tapered screw-threaded stopper,
which being turned is screwed into the neck of the bottle, which is formed with
a female screw therein or into an india-rubber washer placed in the neck of
[Price Gil]

page_text: the bottle, thereby firmly securing the stopper in the bottle or other similar
article.
To carry out my Invention the neck of the bottle or other similar article is made
with a recess in the top part, which is formed rather longer than usual to permit of
a thick india-rubber washer being fitted therein, or the neck of the bottle is made
with a female screw. In the washer is turned a tapered stopper made with a
coarse screw thread. This india-rubber washer presses in the hollow parts of the
screw, or the screw thread of the stopper is turned in the female screw formed in
the neck of the bottle, thereby firmly securing the stopper in the neck of the
bottle. The top of the stopper is made square, six or eight sided, or of other
suitable form, and underneath the top of the stopper is fitted an india-rubber
washer. By unscrewing the stopper the screw is released from the neck of the
bottle or other similar article, and the stopper is easily removed.
But in order to enable my improvements to be better understood I will proceed
to describe the same by reference to the accompanying Drawing, in which Figure 1
represents a section of a bottle with a tapered screw-threaded. stopper screwed in the
neck of the bottle; Figure 2, section of the neck of a bottle with a straight screw-
threaded stopper screwed therein.
Figure 3 represents an outside view of a bottle shewing a section of the neck,
having an india-rubber washer fitted therein, in which is screwed a taper screw-
threaded stopper.
Figure 4 section of the neck of a bottle with india-rubber washer and taper
screw-threaded stopper.
Figure 5 represents a bottle for containing aërated liquid, shewing section of
the neck with a metal cap screwed therein.
Figure 6, plan of the sanic.
Figure 7 represents a section of the neck of a bottle and stopper for aërated
waters.
Similar letters of reference are used to represent similar parts.
A, Figure 1, section of a bottle of the ordinary construction, having a female
screw formed in the top part of the neck B, in which screws a taper stopper C,
made with a coarse screw thread (the extent of taper of the stopper and the pitch
and size of the screw thread may be varied as required). The stopper is made by
preference of glass, but it can also be made of earthenware or other suitable material.
The top D of the screw is recessed, and receives an india-rubber washer E to give
the required pressure and hermetically close the bottle. The recess keeps the
washer in position, and prevents it coming off the screw. The top F of the stopper
is made four, six, or eight sided, or of other suitable shape and form; by unscrewing
the stopper it is easily removed from the bottle. The stopper shewn in Figure 2
is similar in construction to that shewn in Figure 1, but the stopper C is made
straight, and formed with a screw thread which screws into the straight female
screw-threaded neck of the bottle. The india-rubber washer E fits over, and is
kept in its place by the screw.
The top B of the neck of the bottle, shewn in Figure 3, is made with a recess, in
which is fitted a thick india-rubber washer G. This washer can be made of any
suitable material or composition other than india-rubber. In the thick washer is
screwed a taper stopper C made with a coarse screw thread. The india-rubber
presses in the hollow parts of the screw, and firmly secures the stopper in the neck
of the bottle. The top H of the screw is made round, and over which is fitted
an india-rubber washer E to hermetically close the bottle.
Figure 4 represents a similar method of stoppering the bottle to that shewn in
Figure 3, but the top I of the recess, in which fits the washer G, is flanged. The
screw-threaded stopper C'is also made smaller and tapered, and with a smaller
pitch of screw.
Figure 5 represents a bottle for containing aërated water, shewing section of
the neck and stoppering apparatus. The top of the neck of the bottle is made
with a female screw, in which screws the screw-threaded part of a metal cap K.

page_text: The bottom part L is made taper, and over the tapered part is fitted an india-
rubber washer M, in which a marble N firmly presses when pressure is in the
bottle, thus firmly and hermetically stoppering the bottle. The top of the metal
cap K is made with a flange O, in which are made or formed two holes P for
receiving a key with which to turn the screw-threaded cap in the bottle.
The
Figure 7 represents the neck of a bottle for containing aërated water.
india-rubber ring or washer Q is fitted in the screw of the bottle, pressing in the
hollow of the screw. Over the ring or washer is fitted a metal cap R, which is
screwed into the neck of the bottle, the bottom part S pressing on the ring. The
top of the cap is made with a flange O, having two holes P, in which to fit a key
to allow of turning the cap in the screw-threaded neck of the bottle.
Having thus described my improvements, and the best means I am acquainted
with for carrying the same into effect, I would have it understood that I do not
confine myself to the precise details shewn and described, as these may be varied
without departing from the peculiar character of the Invention; but what I do
claim is
Firstly. The construction and employment of bottles or other similar articles
having the top of the necks formed with tapered or straight female screws, in which
screw tapered or straight screw-threaded stoppers, substantially as herein-before
described and represented in the accompanying Drawing.
Secondly. The construction and employment of bottles or other similar articles
having the top of the necks formed with recesses in which are fitted washers of
india-rubber or other suitable material or composition, and in which screw
tapered screw-threaded stoppers, substantially as described and represented in the
Drawing.
Thirdly. The construction of bottles for aërated water or other effervescent
liquids, with female screw-threaded necks, in which metal caps are screwed,
substantially as herein-before described and represented in the accompanying
Drawing.
In witness whereof, I, the said Stephen Walker, have hereto set my hand
and seal, this Sixteenth day of October, in the year of our Lord One
thousand eight hundred and seventy-six.
