Improvements in or relating to Apparatus for Controlling the
Discharge of Liquids under Pressure from Bottles or other
Vessels.
1, HERMANN ROCHOLL, of Minden, Westfalia, and of 12 Waterloo Street,
Glasgow, in the County of Lanark, Scotland, Glass-bottle Manufacturer, 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, which relates to improvements in or relating to apparatus for
controlling the discharge of liquids under pressure from bottles or other vessels, has
for its object to simplify and improve their construction and action.
And in order that my said invention and the manner of performing or carrying
the same into effect or practice may be properly understood, I have hereunto
appended an explanatory drawing showing in sectional elevation a bottle fitted
with my improvements.
The top-piece 1. which is preferably of china, is screwed into the mouth 2. of the
bottle, the joint being made air or gas tight by means of the rubber ring 3. Such
ring should be moistened previous to the top-piece being screwed in, in order that
the joint may be the more readily made secure. 4. is a glass tube which reaches
nearly to the bottom of the vessel. It is attached to the top-piece by means of the
screwed thimble 5, a washer 6. making the joint tight. 7. is a valve kept closed by
internal pressure or by the spring 9, but which may be opened at any time by
pressing the button 8, the dotted lines showing its position when thus open.
9. is a
spring whose function is to cause the valve to return to its seat when the pressure
is taken off the button. 10. is a flexible cap or washer preferably of rubber, its
purpose being to make a joint between the top-piece and the button. 11. is the
spout through which the liquid 12. is ejected, 13. being the compressed gas chamber.
The parts are preferably made of such material as will not readily be affected by
the contained gases or liquids.
The bottle is charged with liquid by means of any ordinary filling apparatus in
which provision is made to press down the button 8, and keep the valve 7. open
during the filling process, the superfluous gas being blown off in the usual way.
Care should be taken that the bottle be not filled to a greater height than
shown
in the drawing, the space 13. being used to contain the compressed carbonic
acid gas. Such gas need not be compressed to a pressure greater than five
atmospheres.
When it is desired to discharge the liquid, the valve 7. is opened and the
compressed gas in the chamber 13. causes the liquid to pass up the tube 4. and out
of the spout 11.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what I
claim is :-
In apparatus for controlling the discharge of liquids under pressure from bottles,
or other vessels, the construction, combination and arrangement of the various
parts consisting of the top piece 1. which is screwed into the mouth of the vessel,

spring 9, flexible cap 10, spout 11, and chamber 13, substantially as herein described
in reference to, and shewn in the annexed drawings.
Dated this 4th day of October 1894.
