IMPROVEMENTS IN STOPPERS FOR BOTTLES FOR AERATED AND OTHER EFFERVESCENT LIQUIDS."
Year: 1876

page_text: LETTERS PATENT to James Bolt and John Weeder, both of Halifax, in the
County of York, for the Invention of "IMPROVEMENTS IN STOPPERS FOR
BOTTLES FOR AERATED AND OTHER EFFERVESCENT LIQUIDS."
PROVISIONAL SPECIFICATION left by the said James Bolt and John Weeder
at the Office of the Commissioners of Patents on the 3rd March 1876.
JAMES BOLT and JOHN WEEDER, both of Halifax, in the County of York. "IM*
PROVEMENTS IN STOPPERS FOR BOTTLES FOR AËRATED AND OTHER EFFERVESCENT
LIQUIDS."
This Invention relates to stoppers adapted to close bottles containing aërated water,
or other effervescing drinks and liquors containing gaseous fluids or fixed air, and
consists in the construction and combination of a valve or "flap" made of india-
rubber or other suitable substance, and which said valve or flap is used in
combination with certain parts of a stopper for which Provisional Protection has
been allowed to the said James Bolt, application dated 15th January, N° 164.
At the bottom of the inside projecting picce described in the aforesaid Provisional
Specification we make a hole of suitable dimensions, and out of the piece of india-
rubber or other suitablo substance slightly altered which is placed on the inside pro-
jection, or by attaching to it another picce (but we prefer to use the piece placed
on the projection) we form the valve or flap, the action of which is as follows:--
When it is required to fill the bottle with the requisite liquid the tube employed
for filling is inserted in the neck of the bottle, and it lifts or holds back the valve or
flap until full, when it is withdrawn, and the valve or flap springs back to its
original position, where it remains firmly compressed by the expansible pressure of
the liquid against the portion of the projection which forms a bearing surface, and
which is greater or smaller according to the size of the hole made therein, we prefer
to have as small a hole as is practicable for the filling of the bottles; in case a largo
hole is made in the projection, we secure by any suitable means a piece of metal,
glass, or other suitable substance on one or both sides of the valve or flap, to
prevent it being forced through the hole or aperture. The said valve or flap is
always closed, whether the bottles be empty or full, or partly so, except at the time
the tube is inserted for filling the same; the advantage thus derived over the

page_text: "
valves or "flaps heretofore used, and which have been made of metal and which
have had a metal hinge or joint which has allowed the flap to fall immediately
upon any of the contents being discharged, will be obvious, and the valves
so constructed have had in the first place to be pushed back by inserting
a pencil, pointer, or other article in the neck to discharge the contents; now
by our improvements, when it is required to empty the bottle of its contents,
the whole stopper is released from its heretofore secured position (it being
held by wire or other suitable material attached to the neck of the bottle) by
means of either the wire or stopper being worked or moved in slots or slits of
suitable form, which are made in projections which extend on the outside of the
bottle, and which are in connection with the inside projection before-named. The
stopper thus released falls or is placed back on to the neck of the bottle, to which it
always remains attached, and does not in any way interfere with the contents
whilst they are being poured out. When empty it is again secured in the neck of
the bottle, the valve still closed, and which remains so until the tube is inserted for
filling.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said James Bolt and John Weeder in the Great Seal Patent Office on the
1st September 1876.
JAMES BOLT and JOHN WEEDER, both of Halifax, in the County of York.
« IM-
PROVEMENTS IN STOPPERS FOR BOTTLES FOR AËRATED AND OTHER EFFERVESCENT
LIQUIDS."
This Invention relates to stoppers adapted to close bottles containing aerated
water, or other effervescing drinks and liquors containing gaseous fluids or fixed air,
and consists in the construction and combination of a valve or flap made of india-
rubber or other suitable substance, and which said valve or flap is used in combination
with certain parts of a stopper A, for which Letters Patent have been granted to the
said James Bolt, dated 15th January 1876, Number 164.
At the bottom of the inside projecting piece marked A' on the accompanying
Drawing, and which is described in the aforesaid Specification, we make a hole B of
suitable dimensions, and out of the piece of india-rubber or other suitable substance
which is placed on the inside projection A¹, or by attaching to it another piece (but
we prefer to use the piece placed on the projection) we form the valve or flap C, the
action of which is as follows:-When it is required to fill the bottle with the
requisite liquid, the tube D employed for filling is inserted in the neck of the bottle,
and it lifts or holds back the valve or flap C until full, when it is withdrawn, and
the valve or "flap” springs back to its original position, where it remains firmly
compressed by the expansible pressure of the liquid against that portion of the
projection which forms a bearing surface, and which is greater or smaller according to
the size of the hole made therein, we prefer to have as small a hole as is practicable
for the filling of the bottles; in case a large hole is made in the projection, we secure
by any suitable means a piece of metal, glass, or other suitable substance, on one or
both sides of the valve or flap, to prevent it being forced through the hole or
aperture. The flap C is always closed, whether the bottles be empty or full, or
partly so, as shewn in Fig. 1, which represents our stopper as applied to an ordinary
half-pint bottle; at the time the tube is inserted for filling the same it is in the
position as shewn at Fig. 2. Fig. 3 shews the position of the stopper when the
contents of the bottle are being poured out. The advantage thus derived over the
valves or "flaps" heretofore used, and which have been made of metal, and which
have had a metal hinge or joint which has allowed the flap to fall immediately
upon any of the contents being discharged, will be obvious, and the valves so
constructed have had in the first place to be pushed back by inserting a pencil,
pointer, or other article in the neck to discharge the contents; now by our improve-
ments, when it is required to empty the bottle of its contents the whole stopper is

page_text: released from its heretofore secured position to that shewn in Fig.
(it being held
by wire or other suitable material attached to the neck of the bottle) by means of
either the wire or stopper being worked or moved in slots or slits e, f, of suitable
form, which are made in projections of the stopper A, which extend on the outside
of the bottle, and which are in connection with the inside projection A¹ before
named. The stopper thus released falls or is placed back on to the neck of the
bottle, to which it always remains attached, and does not in any way interfere with
the contents whilst they are being poured out. When empty, it is again secured in
the neck of the bottle, the valve still closed, and which remains so until the tube is
inserted for filling.
Figs. 4 and 5 are details of the rubber of which the valve or flap is formed,
Fig. 4 shewing the flap C closed, and Fig. 5 shewing it open, as in filling.
Fig. 6 is a plan view of the stopper, shewing the hole B for the insertion of the
tube D.
Having thus described and shewn by Drawings how the Invention may be put
into practise, we would have it understood that what we claim as our Invention,
and believe to be new is, the application and use of a valve or flap attached to a
moveable stopper operated when the contents are being poured out, in manner
substantially as herein shewn and described.
In witness whereof, I, the said James Bolt, for and on behalf of myself and the
said John Weeder, have hereunto set my hand and seal, this Twenty-fourth
day of August, in the year of our Lord One thousand eight hundred and
Witness,
Wч WHITEHEAD,
Patent Agent,
