Improvements in and relating to Measuring-cocks or -Valves.
I, MAX SIELAFF, of 39, Zionskirch Strasse, Berlin in the Kingdom of Prussia,
Germany, 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 refers to cocks or valves, by means of which a definite quantity
of a liquor may be drawn off the store-vessel containing the respective liquor;
my improvements in cocks of that kind relate to the arrangement of channels
allowing the air forced away by the liquor to flow over into said store-vessel.
There is thus secured an easy efflux of the liquid out of the said store-vessel,
as well as an easy influx into the measuring-space proper; the latter may be formed
either by a special vessel connected to the store-vessel by means of the cock, or by
the hollow plug of said cock. By leading the air forced away by the respective
quantity of the liquor into the store-vessel, there is gained the further advantage,
that said store-vessel may he kept hermetically closed.
In order to make my invention more clear, I refer to the accompanying
drawing, in which similar letters denote similar parts throughout the different
figures, and in which:
Figure 1 is a vertical longitudinal section through a mode of construction at
present preferred by me; the measuring vessel being formed by the hollow plug
figures, of the cock; &
Figure 2 is another vertical longitudinal section through the same mode of
construction, the plug being turned by 90º.
B is the store-vessel or reservoir formed in this case by a barrel or cask. The
casing A' of the cock having the plug A contains besides the main-channel 4 a
short upper channel 6 and a longer lower channel 1. The plug A forming a
chamber 9, is in its upper portion provided with the aperture 7, and in its lower
portion with the apertures 2 and 3. If the plug is in the position shown in
Figure 1, the aperture 2 coincides with channel 1, and aperture 7 with channel 6.
The liquid thus enters the chamber 9, through 1 and 2, whilst the air leaves that
chamber through 7 and 6. If thereafter plug A is turned for 90° (compare Figure 2)
aperture 3 of the plug will coincide with a channel 5, adapted to lead the liquor off,
and aperture 7 will coincide with a channel 8, (shown in Figure 1 in dotted lines)
adapted to allow the entrance of air into chamber 9. The air now contained
within said chamber 9, will flow over into barrel B as soon as plug A is again
turned for 90° so as again to fill chamber 9 with the liquor.
I wish it expressly to be understood, that the plug A need not itself form the
measuring-vessel, but that a special measuring-vessel may be used in combination
with a cock or valve having channels and apertures like those of the cock
shown.
Instead of air for refilling the chamber of plug after the liquor has been with-
drawn, there may be used any other gas, for instance such a one, as will be of
special influence upon the respective sort of liquor.
Having now particularly described and ascertained the nature of this inven-
tion, and in what manner the same is to be performed, I declare that what!
claim is: :-
1. As a means for measuring liquors in definite quantities, a cock or valve having
a channel or channels adapted to lead the liquor from the store-vessel into the

page_text: measuring-space, and another channel or other channels adapted to lead the air or
gas contained within said measuring space from the latter into said store-vessel,
for the purpose as described.
2. As a means for measuring liquors in definite quantities, a cock or valve having,
first, a channel or channels adapted to lead the liquor from the store-vessel into the
measuring-space; second, another channel or other chanuels adapted to lead the
air or gas contained within said measuring space from the latter into said store-
vessel; and third, still another channel or other channels, adapted to lead the
outer air or a gas into the said measuring-space, for the purpose as described.
3. As a means for measuring liquors in definite quantities, a cock having a
hollow plug, and a channel or channels adapted to lead the liquor from the store-
vessel into the chamber of said plug; another channel or other channels adapted to
lead the air or gas contained within said chamber into said store-vessel, for the
purpose as described.
4. As a means for measuring liquors in definite quantities, a cock having a plug
containing a chamber adapted to be used as a measuring space; said cock and its
plug being provided, first, with a channel or channels adapted to lead the liquor
from the store-vessel into said chamber; second, with another channel or other
channels adapted to lead the air or gas contained within the said chamber into
said store-vessel; third, with again another channel or other channels adapted to
lead the outer air or a gas into the chamber of the plug; and, fourth, still another
channel or other channels adapted to lead the liquor off the said plug, substantially
as described.
