PROVISIONAL SPECIFICATION.
Improvements in Bottle-necks and in Tap-stoppers to be used
therewith.
I, ROWLAND BROTHERHOOD, of Cambria House, Chepstow, in the County of
Monmouth, Civil Engineer, do hereby declare the nature of this invention to be as
follows:-
My invention relates to improvements in bottle-necks and in tap-stoppers to be used
therewith; but more particularly, to bottles for aerated beverages, either still or
sparkling; the object of the invention being to allow of a portion of the contents
being drawn without impairing the freshness of the remainder.
In carrying my invention into effect, I make the stopper with a port extending
centrally from its outer end for about three quarters of its length, and then opening
out at a right angle through the periphery of the stopper. A special port formed in
the bottle neck or shoulder establishes communication between the end of the said
right angled port and the interior of the bottle.
The turning of the stopper about its axis opens and shuts the line of ports in the
bottle and stopper.
There may be more than one line of ports or the line may be duplicated for less
than its whole length, and the mouths of the ports may be of any suitable shape.
The locking of the stopper is effected by means of projections on the inner end of
the stopper. These pass, as the stopper is pushed into the bottle, below a shoulder or
flange formed on the internal surface of the latter, and engage under the said shoulder
or flange as the ports are being closed, so as to lock the stopper against the expulsive
force of the contents of the bottle.
The top of the stopper is provided with any suitable device for turning it.

COMPLETE SPECIFICATION.
Improvements in Bottle-necks and in Tap-stoppers to be used
therewith.
I, ROWLAND BROTHERHOOD, of Cambria House, Chepstow, in the County of
Monmouth, Civil Engineer, do hereby declare the nature of this invention, and in what
manner the same is to be performed, to be particularly described and ascertained in
and by the following statement :-
My invention relates to improvements in bottle-necks and in tap-stoppers to be used
therewith. Inasmuch as the main object of the invention is to allow of a portion of
the contents of the bottle being drawn off without interfering with the freshness of the
remainder, it is particularly applicable to bottles of aërated beverages either still or
sparkling.
In carrying my invention into effect, I make the stopper with a port extending
axially from its outer end, or top, to nearly the opposite end, or bottom. One or more
side ports, at right angles more or less with the axial port, are formed in the sides of
the stopper, their axes being at right angles more or less with the axis of the first
mentioned port. Special ports are formed in the inner surface of the neck, or
shoulder, of the bottle, and are (according to the conformation of the bottle)
positioned so as to establish communication between the bottle-interior and the
axial port above described when the stopper is turned into the right position. I prefer
to have two ports in the sides of the stopper, and opposite to each other; so that a
quarter of a turn is all that is required to eitner open or close them both, according to
the initial position of the stopper with respect to the neck ports.

In order that my invention, and the means by which the same is to be carried into
practical effect, may be thoroughly understood, I will now describe them in detail,
referring in so doing to the accompanying figures which are to be taken as part of this
Specification and read therewith.
Fig. 1 is a sectional elevation of a bottle and tap-stopper made according to my
invention.
Fig. 2 is a side elevation of the stopper.
Fig. 3 is a sectional plan taken on the line A-B of Fig. 1.
Fig. 4 is a part sectional elevation taken on the line C-D of Fig. 1, but omitting
the stopper.
Fig. 5 is an elevation shewing the bottle opened.
Fig. 6 is a plan of the stopper.
A is the stopper; and a, a are convenient lugs or thumb-pieces formed on the top
of it, by which it can be easily turned in either direction. B is the axial port, and C
is the blind, or closed, end of the stopper.
D is the bottle neck; and E, the packing on the stopper.
F, F are the two side ports, and G G are the neck-ports between the side ports and
the interior of the bottle.
H, H are the projections on the bottom of the stopper; and 1, I are the flanges
under which they engage.
It will be apparent from a consideration of the foregoing, and especially from an
examination, from a practical point of view, of the drawings referred to, that the
present invention refers only to a bottle the axis of whose neck is a linear continuation,
in a more or less direct line, of the axis of the said bottle. Or, to present the idea of
the preceding sentence in another way, the locking device, such as it is described
above, is always and from the nature of my invention necessarily so, within the cavity
of the bottle, and bearing against a seat furnished by the enlargement inwards of the
bottle shoulder, or neck, whichever is the more convenient position for the purpose.
The drawings shew one axial port and two side ports, or what is practically two
lines of ports. I have already pointed out that this arrangement is preferable to only
one side port. It is so for this reason. When there are two lines of ports, air can
flow into the bottle up one side of the axial port, and through one of the side ports, at
the same time that the liquid is flowing out through the other side port and down the
other side of the axial port. Whereas, if there were only a single line of ports, the
liquid and air would tend to block each other, and the former would gurgle out
instead of flowing freely.
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: --
The combination of vertical stopper having an axial port extending for nearly its
entire length, and its bottom end blind or closed; side-port or ports through the
stopper side or sides; neck port or ports to correspond with said side port or ports
respectively projections upon the bottom end of the stopper, and flanges with which
they can engage for the purpose of locking the stopper; as set forth.
