Improvements relating to Closed Vessels for Containing and
Supplying Liquids.
I, PAUL BAUMERT of 58 Mohrenstrasse, Berlin, W. in the German Empire,
Engineer, 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 devices or appliances for enabling liquids to be drawn.
from closed vessels without the use of carbonic acid gas or the like and without the
admission of air.
A vessel constructed to embody these improvements consists of a cylindrical
receptacle containing a spring controlled piston by means of which the contents
may be forced through the outlet? The improved vessel is easily transported and
handled and does not require to be kept in a vertical position.
The
Referring to the accompanying drawing, which illustrates how this invention
may be carried into effect, C is a cylindrical vessel having a lid D and provided
with a piston K. This piston is provided with a packing ring or disc M of any
suitable flexible or elastic material. A spring F is arranged between the cover D
and the piston K in such a manner as always to tend to force the latter downwards.
When the tap H is opened, therefore, the liquid contained in the vessel C
commences to discharge and continues to be expelled until the tap is closed.
spring F is maintained in its proper position by the concentric projections B
and B which are secured respectively to the cover and to the piston. To prevent
compression of air when the piston moves towards the cover and rarifaction when
the piston moves towards the bottom of the vessel, the cover D is formed with an
opening O which also permits the valve L to be opened when the piston has
reached its highest position.
The action of the apparatus is as follows, assuming the receptacle to be filled
with liquid and the piston to be in its highest position as shown in the drawing.
If now, the tap H be opened, liquid will flow out through it owing to the
pressure of the spring F upon the piston K, and this flow will continue until the
tap is closed or the piston has reached the bottom of the receptacle. When the
piston has reached the bottom of its stroke the receptacle may be re-filled by
forcing or pumping the liquid through the open tap H, thus avoiding any
unnecessary exposure to the atmosphere.
After the receptacle has been filled the valve L may be opened to allow the
escape of any air which was originally contained within the tube or channel R
leading from the receptacle to the 'tap.
An indicating device A may be combined with the upper part of the cylinder C
so as to indicate the quantity of or otherwise measure the contained liquid. This
device consists of a flexible or elastic band graduated or suitably marked and
arranged to pass before an opening O'. This band is wound upon a suitable reel
or spindle and has its outer free end attached to the piston K.
As the piston
descends the band is unwound and the different marks pass before the opening O¹
and show the quantity of liquid left. Upon the ascent of the piston the band is
re-wound upon its spindle.

page_text: When the receptacle or cylinder is used for containing fermented or fermenting
liquids which exert a considerable pressure and force the piston still closer
against the cover D, a safety opening $ may be formed in the wall of the cylinder
through which the liquid may escape upon an excessive pressure being reached
without doing any damage.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, declare that what I
claim is:
1. A closed vessel from which liquid may be drawn without the use of carbonic
acid gas or the like and without the admission of air, constructed and arranged
substantially as hereinbefore described and as illustrated by the accompanying
drawing.
2. In a closed vessel of the herein before described type from which liquid may
be drawn, the combination with the piston of a valve L, arranged and operated
substantially as and for the purpose herein set forth and as illustrated by the
accompanying drawing:
3. The combination with the apparatus hereinbefore described of a safety
opening S, substantially as set forth and as illustrated by the accompanying
drawing.
4. In a liquid containing device of the type set forth, a quantity indicating
or measuring device constructed and operated substantially as hereinbefore
described and as illustrated by the accompanying drawings.
5. A closed apparatus for containing liquid which is filled or re-filled by
forcing the liquid through the outlet tap, substantially as and for the purpose
herein before described and as illustrated by the accompanying drawing.
Dated this 18th day of May 1897.
