Improvements in Aerated Mineral Water Bottle Openers.
HENRY LOMAX, of 9, Railway Road, Darwen, Mechanical Engineer, and Joun
TOMLINSON, of Kay Street, Darwen, Colliery Agent, do hereby declare the nature
of this invention to be as follows:-
This invention relates to an improved means of opening aerated mineral water
bottles, by which means, the bottle is hermetically sealed, before the ball or stopper
is released from its place in the neck of the bottle.
This is accomplished by means of the following arrangement.
We use the ordinary circular cup, made of wood or other suitable material,
with its pin or peg in the centre, the outer end of which is dished, so that when
pressed against the ball, it centres itself on the perhiphery of the ball, and prevents
the end of the pin or peg disturbing or unseating the rubber forming the air-
tight cushon around the ball. This pin or peg 18 surrounded by a conically formed
spiral spring.
Around the pin or peg is a disc of cloth or other material, which when pressed
against the neck end of the bottle first' makes it air tight, which on being further
pressed whilst being kept air tight, the pin or peg dislocates the ball, thus the
atmosphere is excluded from sudden contact with the gas in the bottle, thus keep-
ing the contents of the bottle from being splashed and wasted, and also permits
the gas to enter the chamber or cup in the pusher.

Improvements in Aerated Mineral Water Bottle Openers.
We HENRY LOMAX, of 9, Railway Road, Mechanical Engineer, and JOHN
TOMLINSON, of Hay Street, Colliery Agent, both in Darwen, in the County of
Lancaster, 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:-
This invention relates to an improved means for opening or releasing the
inwardly seated stoppers of aerated mineral water bottles, by the application of
which improved means the rim of the bottle neck is practically hermetically sealed
before the stopper is depressed or released from its seat so that the effusion of the
[Price 8d7

unavoidable with bottled aerated waters in good condition.
In carrying out this invention we prefer to construct the improved means or
openers ás hereinafter described and as illustrated in the accompanying sheet of
drawings, to which drawings reference will now be made.
In the said drawings Fig. 1, represents an elevation, Fig. 2, a vertical section
of our improved bottle opener and Fig. 3, a plan of the underside.
A cup a is formed of wood or any other suitable material preferably in the form
illustrated. Such a cup has hitherto been used for the purpose of releasing the
stopper and was provided with a central peg which when the cup was pressed,
displaced the stopper, the cap simply acting as a shield for confining the splash-
ing of the contents. According to our invention the cup a which is formed inside
large enough to embrace the rim of the bottle mouth, is also provided with a
peg al by which the stopper is displaced when the cup is pressed.
We prefer to hollow the end of the peg as shewn on Figure 2, in order to
enable it to centre itself upon the crown of the stopper which is generally spherical
or convex, and for the purpose of preventing the peg from displacing the india-
rubber seating of the stopper. This hollow face as is preferably formed as a

than one, having a rigid backing formed by a washer c
disposed a helical or coned spiral spring d. We prefer at present to employ
two discs of the flexible material b and b¹. These discs are formed preferably to fit
the inside wall of the cup, and have central holes which fit and are capable of
sliding upon the peg a¹.
In the use of the apparatus the disc 6 first comes in contact with the rim of the
bottle neck. A comparatively tight joint is thus made between it and the said
rim, owing to the disc being flexible and of soft material. Upon pressure being
applied to the cup, the peg advances and depresses the stopper. The effusion of
the contents is checked by the flexible disc and by the joint made between the
disc b and the rim of the bottle neck and by the joint round the central peg, but
the pent up gas can find its way out gradually at the two joints, first into the
hollow of the cup. Thus by the checking of the rush of gas and by diffusing
it first into the cup, waste of the contents of the bottle is prevented and splashing
avoided.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what
we claim is:
The improved construction of opener for bottles containing acrated mineral
waters and the like, which opener consists of a cup-shaped body having a central
projecting peg inside of the cup and an annular disc or pad large enough to cover
the rim of the bottle mouth but preferably filling the area between the peg and
the inside wall of the cup and backed by a suitable spring, which pad when the
opener is in
use presses upon the rim of the bottle mouth and per
mits the bottle stopper to be pressed down by the cup body and peg
thereby releasing the enclosed gases in a more gradual manner and preventing
the diffusion and waste of the contents substantially as described and illustrated
herein before and by the accompanying sheet of drawings.
