PROVISIONAL SPECIFICATION.
An Improved Cock for Racking off Wines, Ale, Porter, and
other Liquors.
I, FRANCIS ALLEN ROCHE, of 7, St. Luke's Place, in the City of Cork,.
Ireland, Mechanical Engineer, do hereby declare the nature of this invention to be
as follows:-
My invention relates to an improved construction of cock or faucet for racking
off wines, ale, porter and other liquors, the object being to afford an unobstructed
passage for the liquor entering a cask or other vessel and, at the same time, allow a
free exit of the air from the said vessel.
For this purpose I form the body of the cock with two nozzles, one for the inlet.
of the liquor, and the other for the outlet of the air, and with a conical end to.
admit of its being fixed in the bung hole or other opening in the cask or other
vessel.
The passage in the plug of the cock is formed with perfectly parallel sides and
an annular space is left between the lower end of the plug and the conical end of
the body. The plug is made with an opening forming a communication between.
the said passage and the inlet nozzle, as usual, and with another opening forming a
communication between the said annular passage and the air-outlet-nozzle.
With this construction a single movement of the handle of the cock will open or
close both the liquor inlet and the air outlet, thereby avoiding the use of a non-.
return valve, either on the air-nozzle or on the racking apparatus.
It is of great importance that the air-nozzle or its pipe should not become
permanently charged with liquor and my improved racking cock allows the release
of such liquor from the air-nozzle or pipe of one cask or vessel by simply opening.
the cock in the next cask or vessel, thereby avoiding the obstruction which is caused.
when using a non-return valve.

COMPLETE SPECIFICATION.
An Improved Cock for Racking off Wines, Ale, Porter, and
other Liquors.
I, FRANCIS ALLEN ROCHE, of 7, St. Luke's Place, in the City of Cork,
Ireland, Mechanical 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:-
My invention relates to an improved construction of cock or faucet for racking
off wines, ale, porter and other liquors under pressure, the object being to afford an
unobstructed passage for the liquor entering a cask or other vessel and, at the same.
time, allow a free exit of the air from the said vessel.
In the accompanying drawings-
Figure 1 is an elevation; and, Figure 2 is a vertical section of a cock for racking
off wines, ales, porter, and other liquors, constructed according to my invention:
Figure 3 is a horizontal section on the line A B of Figure 2; and,
Figure 4 is a similar view on the line C D of Figure 2.
Similar letters in all the figures indicate similar parts.
According to my invention I form the body a of the cock with two nozzles b, c

page_text: for the inlet of the liquor and outlet of the air and fob or foam respectively, and
with a conical end d to admit of its being fixed in the bung-hole or other opening of
the cask or other vessel.
The passage e in the plug f of the cock is formed with perfectly parallel sides
and an annular space g is left between the lower end of the plug and the conical
end of the body a. The plug is made with an opening h, Figure 3, forming a
communication between the passage e and the inlet nozzle b, as usual, and with
another opening, Figure 4, forming a communication between the annular space g
and the air and fob outlet nozzle c.
With this construction a single movement of the handle of the cock will open for
close both the liquor inlet b, and the air and fob outlet e, thereby avoiding the use
of a non-return valve, either on the air-nozzle or on the racking apparatus.
It is of great importance that the air and fob nozzle c or its pipe should not
become permanently charged with the liquor shut in the said nozzle or pipe when
changing casks, and my improved racking cock allows the release of such liquor
from the air-nozzle or pipe of one cask or vessel by simply opening the cock in the
next cask or vessel, thereby avoiding the obstruction which is caused when using a
non-return valve. If the air-pipe attached to the nozzle be led to the top of the
racking tank the fob in the said pipe will be forced into the tank by the ascending
air, thus avoiding the necessity for a separate fob tank or vessel.
C
Part of the air and fob pipe is of glass to allow of ascertaining when the cask or
other vessel is full.
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. A cock for racking off wines, ale, porter and other liquors having its body
formed with two nozzles for the inlet of the liquor and the outlet of air and fob or
foam respectively, and with a conical end; and its plug formed with two openings,
one of which forms a communication between the liquor inlet nozzle and the passage
in the plug and the other between the air and fob outlet nozzle and an annular
space between the lower end of the plug and the conical end of the body, sub-
stantially as and for the purposes herein before described.
2. The improved racking cock hereinbefore described and illustrated in the
accompanying drawings.
