Improved Closure for Use in connection with Cooler Doors.
I, PETER STAHL, Engineer of 15 Mittererstrasse, Munich, Bavaria, Germany,
do hereby declare the nature of my invention and in what manner the same is
performed to be particularly described and ascertained in and by the following
statement:-
The present invention relates to an improved closure for use in connection with
coolers for cooling the contents of casks, said closure being adapted to close the
cooler round the tap of the said cask, which projects out through the cooler wall to
enable the contents of the cask to be drawn off.
Owing to the fact that the position of the tap in the cask often varies in height,
it has hitherto been necessary to have a slot in the cooler doors or wall to allow for
this variation in height in various casks and consequently a part of the said slot
which was not filled out by the throat of the tap remained open, allowing the
exterior warmth to penetrate into the cooler and causing the cooling medium
therein to get exbausted more quickly, than if the cooler were closed tightly round
the tap throat.
By means of the present invention I provide a closure by means of which the
cooler will always be closed tightly round the throat of the tap.
And in order to make the present Specification more easily intelligible reference
is had to the accompanying drawing in which similar letters denote similar parts
throughout the several views:―
Fig. 1 being a front elevation of the closure,
Fig. 2 a vertical section through the centre of the same,
Fig. 3 a horizontal section along the centre line of the same.
c is the throat piece having interior rings of elastic material adapted to close
round the throat of the tap or cock, c' is the foot or slide piece of the said throat
piece c, adapted to slide in guides a a attached to the plates & let into the doors A A
of the cooler. The throat piece c and foot c' are divided into two halves along the
vertical centre line, and one half as also one guide a is fixed to each door of the
cooler. One half is also provided with a lap to overlap the opposite half when
the doors are closed. Springs gg are provided between the upper surface of the
slide or foot c' and the under surface of the guides a a. A slot B corresponding in
width about to the bore of the throat piece, is provided half the said slot being cut
in each door.
Thus when the cask has been placed in the cooler, the vertical position of the
throat piece may be adjusted to suit the position of the tap of the said cask which
has to extend out of the cooler, and will by means of its packing rings d d' close
air tight round the throat of the said tap or cock, whilst by means of the springs 99
the foot of the said throat piece e will be tightly pressed against the plates b b and
will consequently securely close the remaining parts of the slot which had otherwise
remained open.
Having now particularly described and ascertained the nature of my invention
and in what manner the same is performed I declare that what I claim is :-
1. A device in connection with the doors of a cooler for enclosing the throat of
the cock or tap of the cask in the said cooler, consisting of the combination of a
throat piece c, having suitable interior packing rings, and having a foot or guide
plate c', the whole being vertically divided, along the line of juncture of the doors
of the cooler, means for guiding the said throat piece vertically, a vertical slot B in

page_text: the said doors, and. means for pressing the said foot c¹ against the doors for the
purpose substantially as described.
2. The combination of the throat piece c having interior packing rings d d¹ and
foot or guide plate c', the whole heing divided vertically along the line of juncture
of the doors of the cooler, the angle guide pieces a a attached one to each door of
the cooler, slide plates bb let into each door of the said cooler to which the said
guides are attached and springs arranged between the said guides and the outer
surface of the foot e substantially as described.
