COMPLETE SPECIFICATION.
An Improved Stopper for Bottles, Jars, and other Vessels.
We, JOHANN NADLER, Engineer, and REINHOLD MERKELT, Householder, both
residing 36 Alfred Place, Store Street, Tottenham Court Road, London, 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 automatic stoppering devices for bottles which may be
applied to any vessel or jar containing liquids developing carbonic acid. In
comparison with 'the hitherto known stoppers my stoppering device can readily be
fastened and easily be manipulated. The emptying of the bottle is effected by means
of a light pressure exerted upon a central button.
"The invention is shown in the accompanying drawing.
Fig. 1 is a cross section of the stopper in its closed condition and
Fig. 2 a cross section in its open condition.
:
"'h is a hollow cylinder, the upper enlarged part of which is provided with an inner
thread into which is screwed a second hollow cylinder c, the upper end of which has
an outer thread into which is screwed a third hollow cylinder. Into the hollow
cylinder fits, exactly a second cylinder 9., provided with an inner thread. The
hollow-cylinder his narrowed on its lower end for the purpose of preventing the
rotatable hollow cylinder g from falling out of the cylinder h. Into the hollow
cylinder. g. is screwed another hollow cylinder. k provided with a flange k", and
carrying a cylinder of india rubber i which by rotating the hollow cylinder g is
compressed between the flange " of the hollow cylinder k and the hollow cylinder, so
that the diameter of the cylinder i, is considerably increased. The moveable cylinder e
centrally held in the two upper hollow pieces and is provided on its lower end with
a-disc el bearing against a disc of india rubber fintercalated between the cylinders c
and h. On its upper end the cylinder e is threaded and screwed into the button a.
Below this button there is arranged a hollow cylinder of india rubber d having the
tendency of pressing the button a and in consequence also the cylinder e upward and
moreover it tightens the hollow piece b to the outside. The cylinder e is provided
above the disc el with a longitudinal slot e', which may be substituted also by two
smaller superposed openings communicating with a central boring of the cylinder e.
The hollow space c¹ of the hollow piece c is in direct communication with the hollow
space of the hollow piece b and the latter with the outlet-passage b¹.
In order to fasten the stoppering device upon the bottle or another jar or vessel,
first the hollow cylinder h with the hollow cylinders g and and the ring of india
rubber is inserted in the neck of the bottle, whereupon the hollow cylinder 9 is
rotated by means of a key engaging into the recesses , so that the hollow piece k is
screwed into the hollow cylinder and the ring of india rubber i is compressed.
The hollow cylinder g is rotated until the ring of india-rubber i bears firmly against
the walls of the neck n. The latter is narrowed upward, so that the ring of india-
rubber is pressed by the inner pressure existing in the bottle, always more tightly
against the walls insuring thereby a perfect tightness.
In order to fasten more firmly the stopper there is inserted at the upper end of the
bottle a second ring of india-rubber l. The hollow piece c is screwed then into
the hollow piece b. The cylinder e is passed through the disc of india-rubber f, the
hollow pieces cand..6 and the cylinder of india-rubber d, and it is screwed into
the button a.
After this has been done, this upper part is firmly connected with the

page_text: lower part by screwing the cylinder ċ into the cylinder h, and the stoppering device
is ready for use. The bottles are filled in the commonly known way. For emptying
the bottle the button a is pressed down, so that the slot e' of the cylinder is in
communication with the hollow space 9' of the cylinder g and in consequence through
the glass-pipe m with the interior of the bottle. The liquid, under the action of the
inner pressure ascends through the pipe m and enters through the slot e', the hollow
space c', and then the hollow space 61 and it passes thence through the outlet-
passage into the open air. When the pressure exerted on the button a ceases, the
latter, under the action of the inner pressure existing in the bottle against the disc e",
and under the action of the cylinder of india-rubber d moves upward, so that the
disc ell bears against the disc of india rubber shutting off thereby the interior of the
bottle against the outer air.
Having now fully described and ascertained the nature of our "said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :
1. An automatic stoppering device for bottles containing liquids developing
carbonic acid, characterised by a valve cylinder e provided with a longitudinal slot e
and susceptible of being pressed downward by means of a button a to such an extent,
that the slot e¹ communicates with the interior of the bottle and the liquid is
allowed to flow out through the hollow spaces c¹ 61 of the hollow pieces c d and
through the outlet-passage b", while when the pressure, ceases, the valve-cylinder
under the action of the cylinder of india-rubber d ascends until its disc ebears
against the disc of india rubberfforming thus a tight closure substantially as above
described and shown in the accompanying drawing.
2. The fastening of the stoppering device characterised in Claim 1 in the neck of
the bottle in such a manner, that the cylinder of india rubber, by rotating the
hollow cylinder 9 and by screwing thus the hollow piece into the hollow,
cylinder g, is compressed between the flange kl and the hollow cylinder h, hearing
by this means tightly against the walls n of the neck, while the hollow piece his
fixed by a ring of india-rubber in the neck of the bottle and connected by
screwing with the hollow piece c, substantially as set forth and shown in the
accompanying drawing.
