Improvements in Means of Opening Bottles Containing Liquids
under Pressure.
I FREDERICK FOSTER of Niagara Works Eagle Wharf Road Hoxton in the ("ounty
of Middlesex Engineer do hereby declare the nature of this invention to be as
follows:-
The object of this invention is to provide means for facilitating the opening of ball
stoppered bottles containing liquids under pressure.
For this purpose I fit each bottle with a staple having trunnions at each extremity
which rest upon the india rubber ring in the groove made in the bottle mouth.
This staple is thus held by its trunnions in position above the india rubber ring and
is capable of movement from side to side of the bottle mouth overlapping the ball
stopper and rotating upon its trunnions for this purpose.
A projecting piece or "trigger" is attached to the staple, suitably shaped at one
end to be operated by hand for moving the staple and formed into a curved pricker at
its opposite end.
The curved pricker bears against the ball stopper in contact with which it moves
until it reaches the india rubber ring between which and the ball stopper its point is
forced sufficiently to cause an escape of gas whereby the ball stopper readily falls into
the bottle which is thus safely and expeditiously opened.
The staple with its "trigger" and pricker is formed in one piece by stamping and
is bent into the required form as shown by the accompanying drawings in which
Fig. 1 shows in section the neck of a bottle closed by the ball stopper A and fitted
with the "trigger-opener B shown with the prick r C in position to be forced
between the ball A and the india rubber ring which forms the seating for the ball.
"
Fig. 2 shows the "trigger-opener" B in position after the ball stopper has fallen
from its scating by reason of the escape of gas.
"
Fig. 3 shows the "trigger-opener" removed from the bottle. B is the "trigger
by which the opener is operated. C is the pricker which is forced between the ball
stopper and the india rubber ring to cause the required leakage. D is the staple
overlapping the ball stopper and E. E. are the trunnions by which the " trigger-
opener" is held in position in the bottle mouth. Fig. 4 is a plan of Fig. 2 and in all
the Figures the same reference letter indicates the same part."
COMPLETE SPECIFICATION.
Improvements in Means of Opening Bottles Containing Liquids
under Pressure.
I FREDERICK FOSTER of Niagara Works Eagle Wharf Road Hoxton in the County
of Middlesex 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:—
The object of this invention is to provide means for facilitating the opening of
ball stoppered bottles containing liquids under pressure.
For this purpose I fit each bottle with a staple having trunnions at each extremity
which rest upon the india rubber ring in the groove made in the bottle mouth.
This staple is thus held by its trunnions in position above the india rubber ring
and is capable of movement from side to side of the bottle mouth overlapping the
ball stopper and rotating upon its trunnions for this purpose.

page_text: A projecting piece or trigger is attached to the staple at one end to be operated
by hand for moving the staple and is formed into a curved "pricker" at its opposite
end.
The curved pricker" bears against the ball stopper in contact with which it moves
until it reaches the india rubber ring between which and the ball stopper its point
is forced sufficiently to move the ball stopper laterally and so cause an escape of gas
on one side of the ball whereby the ball stopper readily falls into the bottle which is
thus safely and expeditiously opened.
The staple with its "trigger" and "pricker" is formed in one piece by stamping
and is bent into the required form as shown in the accompanying drawings in which
Fig. 2 is a perspective view and Fig. 3 a sectional view of the neck of a bottle closed
by the ball stopper A and fitted with the "trigger opener" B shown with the
"pricker" C in position to be forced between the ball A and the india rubber ring
which forms a seating for the ball. Fig. 4 is a perspective view and Fig. 5 a
sectional view showing the "trigger opener "B in position after the hall stopper has
fallen from its seating. Fig. 1 shows the "trigger opener" removed from the bottle.
B is the "trigger" by which the opener is operated.
C is the " pricker" which is
to be forced between the ball stopper and the india rubber ring to move the ball and
so cause the required leakage. D is the staple overlapping the ball stopper and E E
are the trunnions by which the "trigger opener" is held in position in the bottle
mouth. In all the above mentioned figures the same reference letter indicates the
same part.
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
1. The
"
trigger opener" hereinbefore described and particularly illustrated
by Fig. 1 of the accompanying drawings to be used for the purpose of opening
internal ball stoppered bottles.
2. Fitting internal ball stoppered bottles with "trigger openers" in the manner
hereinbefore described and illustrated by Figs. 2, 3, 4 and 5 of the accompanying
drawings to move the ball laterally and so cause an escape of gas when it is required
to open the bottle.
