Improvements in Vessels for Containing Liquids.
1, FREDERICK WILLIAM GOLBY, of 36 Chancery Lane, in the County of
Middlesex, Patent Agent, do hereby declare the nature of this invention and in
what manner the same is to be performed, as communicated to me by Paul
Lochmann, of Langestrasse 27, Leipzig-Gohlis, Saxony, Germany, Director, to be
particularly described and ascertained in and by the following statement :-
The object of the present invention is to construct a vessel in such a manner
that its capacity may be varied at pleasure, without allowing air to enter there-
into. The vessel therefore, is well adapted for containing and preserving liquids
which are liable to become stale, such as beer, wine or the like, and which, at
different intervals of time, require to be tapped off in greater or smaller quantities
without admitting air into the interior of the vessel. By placing such liquids in
vessels of the kind hereinafter described the liquid will be preserved for a long
period of time.
In the accompanying drawings, Fig. 1 represents a longitudinal section through
a vessel constructed according to this invention which consists of an outer vessel to
which is connected by a rubber diaphragm, a hollow dished cover, the vessel and
the cover being drawn out as far as possible one from the other; Fig. 2 is a
similar view of the same with the hollow dished cover inserted half way into the
outer vessel, and Fig. 3 is a similar view showing the hollow dished cover
completely pushed into the outer vessel.
The outer vessel a and the hollow dished cover 6 fit together and are united by
means of a rubber diaphragm or connection c made airtight at the joints in any
suitable way.
1 now the vessel a and cover b (Fig. 1) united by the rubber connection c,
are pushed one into the other (as in Figs. 2 and 3) in such a way that the rubber
connection c forms a part of the vessel, a more or less rapid discharge of the
vessel a containing the liquid may be obtained through the outlet f, by means
of suitable pressure on the cover b, i.e., the capacity of a may he diminished at
pleasure.
It is advisable to make the hollow dished cover of such depth that with the wall
of the rubber connection c it is equal to the depth of the vessel a. The vessel
itself may, of course, be formed in any way; with a conical vessel and conical
cover however, such as is shown Figs. 1 to 3, the annular space between the
vessel a aud cover b and the rubber connection c, which cannot be utilized, will be
the smallest possible.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, 1 declare that what I
claim is ;-
A vessel, whose capacity may be varied at pleasure for containing and
preserving liquids which easily become stale, characterized by an outer vessel and
a hollow dished cover joined together by a rubber connection, and which can be
pushed one into the other in such a way that in order to completely discharge the
outer vessel, the outside wall of the hollow dished cover, and of the rubber
connection, fit closely against the inside wall of the outer vessel, thus causing the

page_text: expulsion of the whole quantity of liquid substantially as described with reference
to the accompanying drawings.
