Complete Specification Left, 25th Feb., 1896-Accepted, 28th Mar., 1896
I, PAUL ROBERT WIESNER, of 64 Gordon Street, Glasgow North Britain,
Surgical Instrument Maker, do hereby declare the nature of this invention to be
as follows:
My invention relates to an improvement in stoppers, and has for its object to
construct these so that by simply reversing the plain air-tight stopper it is capable
of regulating the flow or drip of the liquid from the bottle, more especially in the
administration of anesthetics.
The stopper is of a double or interchangeable form or configuration, and may
be made of glass, metal, or cork, or other suitable material. One portion con-
stitutes the cork or air-tight stopper, while the other regulates the drip or flow of
the liquid. This latter portion is provided with two orifices or passages, one of
which acts as a passage for the discharge of the liquid, while the other allows air
to pass in to the bottle to facilitate the drop.
When it is desired to pour out any of the liquid from the bottle, the air-tight
stopper is simply taken out of the neck of the bottle, and the portion for regulating
the drip or flow of the liquid inserted therein, and the bottle is turned up, when
the liquid drops out. The flow or drip can be regulated by placing the finger
over the upper orifice.
According to existing stoppers great care must be taken when not being used
to see that the orifices in the neck of the bottle are properly closed up so as to
prevent evaporation, but it will be obvious that according to my improvements
there is no chance of evaporation taking place, because at a glance and without
the slightest trouble it can be seen whether the bottle is properly stopped.
The stopper made according to my improvements can be adapted to any bottle.
Dated this 24th day of May 1895.

COMPLETE SPECIFICATION.
An Improvement in Bottle Stoppers.
I, PAUL ROBERT WIESNER of 64, Gordon Street, Glasgow North Britain,
Surgical Instrument Maker, 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 an improvement in bottle stoppers, and has for its object
to construct these so that by simply reversing the plain airtight stopper it is
capable of regulating the flow or drip of the liquid from the bottle more especially
in the administration of anæsthetics."
Figure 1 is a section of a bottle with stonner

page_text: The stopper is of a double or interchangeable form or configuration, and may
be made of glass, metal or cork, or a combination of both, or other suitable
material. One portion A constitutes the cork or airtight stopper, while the other B
regulates the drip or flow of the liquid. This latter portion B is provided with
two orifices or passages c, d, one c of which acts as a passage for the discharge of
the liquid, while the other d, being a little larger, allows air to pass in to the
bottle to facilitate the drop. Or the orifices or passages c, d, may be independent
tubes passing through the portion B and the air tube d may be extended so that
it will pass into the bottle as shewn in Figure 3.
When it is desired to pour out any of the liquid from the bottle the airtight
stopper A is simply taken out of the neck E of the bottle F, and the portion for
regulating the drop or flow of the liquid inserted therein, and the bottle is turned
up when the liquid drops out as seen in Figure 1. The flow or drip can be
regulated by placing the finger over the upper orifice d.
According to existing stoppers great care must be taken when not being used
to see that the orifices in the neck of the bottle are properly closed up so as to
prevent evaporation, but it will be obvious that according to my improvements
there is no chance of evaporation taking place, because at a glance and without
the slightest trouble it can be seen whether the bottle is properly stoppered.
The stopper made according to my improvements can be adapted to any bottle.
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 :-
:―
A bottle stopper constructed, substantially as and for the purposes hereinbefore
described and illustrated on the accompanying sheet of drawings.
Dated this 24th day of February 1896.
