COMPLETE SPECIFICATION.
An Improved Apparatus for Discharging Liquids from Fermenting
Vats or Vessels.
I, XAVER REISCH BÖCK, of Cüstrin, in the Empire of Germany Master-Brewer,
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 :-
My invention relates to apparatus for discharging liquids of any kind from
fermenting vats or vessels without any loss; which apparatus operates with
absolute certainty its manipulation being very simple.
In the accompanying drawings-
Figure 1 represents a vertical section of my improved apparatus applied to a
fermenting vat or vessel.
Figure 2 shows an elevation of the sieve closing device.
This improved apparatus consiste substantially of three main parts; that is to
say a short tube a secured in the bottom of the fermenting vat or vessel a sieve
closing device b guided vertically in the said tube a and a discharge cock c of well
known construction, which can be secured to the lower part of the tube a by means
of a coupling.

At its two extremities the tube a is provided with exterior screw threads d and e
upper extremity being screwed into the bottom S of the fermenting vat or
el so that the edge g of this tube will be flush with the upper face of the
.om S. The interior of the tube a is turned smooth throughout its length at its
lwer end a recess is turned upon its interior surface for the reception of a broad
ia-rubber ring o held in position by means of a pin. Below the india-rubber
r.ng o I arrange an adjusting ring hand on the outer side of the tube a I provide
a screw thread e for securing the discharge cock c to the said tube. The sieve
closing device is made as a plug, a packing ring i of india-rubber being provided
thereupon, and a hole is provided in an extension k of the plug by which it is
enabled to be removed by means of a bent wire rod after the fermenting vat or
vessel has been emptied. The sieve is intended to prevent the passing out of the
vat, through the tap c with the liquid of anything that may have fallen into the
vessel, such as spigots bungs etc.
The discharge cock c has a tubular extension 7 which fits very tightly against
the inner periphery of the tube a and such cock may be fixed to the tube by
means of an adjusting ring m for which purpose a collar is provided on the tubular
extension of the cock c. This cock has a discharge outlet provided with a screw
thread for securing an india-rubber pipe or hose thereto.
My improved apparatus operates as follows-
For filling a fermenting vat or vessel the sieve closing device is inserted into
the tube a; the india-rubber ring i will then bear against the upper edge of the
tube a and by reason of its weight and the liquid above it will be pressed against
the said tube, thus making a durable and perfect joint until the fermenting vat or
vessel is emptied. When the emptying is to take place, the tubular extension of
the cock c is inserted from below into the tube à until the screw thread in the
coupling m comes in contact with the screw thread e on the tube a, whereupon the
said cock is fixed in its position. In this operation the sieve closing device is raised
by the tubular extension on the cock c so that the sieve projects into the fermenting
vat or vessel, being guided in the tube a to such an extent that it will not be liable

The sediment and the coarser particles which float in the liquid are retained by
the sieve. When a fermenting vat or vessel is not to be completely emptied the
cock c is closed and the coupling of the same is disconnected from the tube a after
the desired quantity of liquid has been discharged, then the cock is slowly
withdrawn so that the sieve closing device will descend and make au absolutely
tight joint again.
• Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is―
1. An apparatus for discharging liquids from fermenting vats or vessels, com-
prising a tube a fixed in the bottom of such vat or vessel and a sieve closing
device guided vertically in the said tube, wherein a tubular extension on the
cock c can be moved up and down and fixed by means of a coupling, the sieve
closing device being opened by the upward movement of the cock for the purpose
of discharging the fermenting liquid and tightly closed again by the downward
movement of the cock, substantially as set forth.
