Improvements in or relating to Vessels for Containing Liquids.
I, 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 present invention relates to apparatus or vessels for containing, transporting
and preserving liquids of all kinds by means of which the liquid may with the
greatest facility he emptied, from the vessel without the admission of atmospheric
air thereinto. With but little trouble small quantities of beer, wine or other liquids
with which the vessel is filled, may be discharged without in the slightest degree
impairing the good quality of the liquid, remaining in the vessel, which keeps of
the same good quality until it is completely consumed.
The accompanying drawing shews two modes of carrying the invention into
effect.
Fig. 1 shews a liquid vessel in the form of a bottle, containing in its interior an
elastic bag or expeller, and an air-pump for filling the same.
Fig. 2 shews a cylindrical liquid-vessel containing in its interior an elastic bag
or expeller an air-pump and an ice container or cooling chamber, surrounding the
pump and serving to keep both pump and liquid cool.
The apparatus consists of a liquid-vessel with a distensible bag or chamber or a
Both distensible bag or
membrane for that purpose, inserted in its interior.
chamber and membrane, when exposed to a pressure of air or gas tend to become
distended and by their expansion force the liquid out of the vessel as soon as the
tapping ceck, or other tapping contrivance, is opened. During or after the
discharging of the liquid, atmospheric air cannot, however enter into the vessel so
that the durability of the liquid is warranted. Now the principal reason why beer,
wine or other liquids become stale or thick, must as a rule be ascribed to the fact
that atmospheric air gets mixed with the liquid in the vessel.
The vessel a may be of any suitable form, for instance, as that of a bottle as
shewn in Fig. 1, as a cylindrical vessel as shewn in Fig. 2, or it may be shaped in
any other way desired. Into the vessel a an elastic bag or expeller 6 is inserted
or, in place of the latter, a membrane which is fixed to the closing device of the
vessel and which must be barred against the outside by means of a non-return
valve v.
Air. carbonic acid or gas, or any suitable liquid, is pamped into the bag
or expeller b or against a membrane thereby causing the liquid in the vessel a by
the expansion of b, to be forced out through the outlet e when the tapping cock d
is opened, without atmospheric air being able to enter the vessel. In order to
inflate the bag or expeller b, an air-pump 1. e that shewn in Figs. 1 and 2, or other
means of conducting or fore ng fluids, ma be used. Thus the bag or expeller b
may le connected with a carbonic acid-bottle, or with a conduit and, according to
the requirements, gas, water, or air may admitted through a cock, or the like,
arranged for the purpose. In order conpletely discharge the vessel the
cock d is connected with the lower part o he same by the tube g. The pistonsk
of the air-pump may be either directly supplied with valves or flaps o as in Fig. 2 or
may be in connection with a valve in the bottom of the pump cylinder, as shewn
in Fig. 1. The piston rod p and handie serve to facilitate the management of
the pump.
In the vessel a a refrigerator y also be arranged, between 2 and mas

page_text: in Fig. 2, or in any other way, serving at the same time for cooling the liquid and
the pump, so that the air or the like, passes into the expeller b in a cold state, and
the liquid is cooled from inside. The cylinder and refrigerator may suitably be
covered by lids n and m. According as it is intended to draw a large or a small
quantity of the liquid from the vessel a, the expeller 6 or, the inserted membrane
must be inflated in order, by its expansion, to force the liquid when the tapping
cock is opened. The pump and the discharge cock may be fastened together on
the closing cap of the vessel, as in Fig. 1, or directly to the vessel or to its lid 7,
and separate from each other as shewn in Fig. 2. The elastic expeller or the
membrane may be arranged in any suitable shape and manner.
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;-
1. An apparatus or vessel for containing, transporting and preserving liquids
characterized by an elastic bag or expeller or, a membrane, placed in the interior of
the vessel in such a way that, by inflating the expeller or by bringing the membrane
under pressure by means of air, gas, water or the like, the liquid is forced out of
the containing vessel, without allowing atmospheric air to pass thereinto,
substantially as described.
2. The addition to an apparatus or vessel of the kind indicated in the preceding
claim, of an ice container or cooling chamber arranged in such a way that the
liquid in the vessel as well as the air or other means for inflating the bag or
expeller, or the membrane, is cooled in the pump before getting into said bag or
expeller or the membrane, substantially as described.
