PROVISIONAL SPECIFICATION.
Improvements in Cocks for Racking off Wines 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 racking off cocks and especially to cocks of the kind
described in the Specification of former Letters Patent granted to me No. 9793
of 1891, the object of my present invention being to provide means for preventing
any liquid which may remain in the pipe connected with the outlet of the cock
from being retained therein when the cock is moved from one cask or vessel to
another.
In carrying out my invention I form in the body of the cock opposite to the
liquid and air-inlet and escape nozzles a recess or by-pass extending from the
liquor inlet in the plug of the cock to the air-port in the said plug. When the
cock is closed this recess or by-pass establishes communication between the liquor
passage of the cock and the air-passage thereof in order that as the cock is lifted
from a cask or other vessel the air may enter and allow the liquid to flow out.
Dated this 21st day of November 1893.

COMPLETE SPECIFICATION.
Improvements in Cocks for Racking off Wines 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 racking-off cocks and especially to cocks of the kind
described in the Specification of former Letters Patent granted to me No. 9793 of
1891, the object of my present invention being to provide means for preventing
any liquid which may remain in the pipe connected with the outlet of the cock
from being retained therein when the cock is moved from one cask or vessel to
another.
In carrying out my invention I form in the body of the cock opposite to the
liquid and air-inlet and escape nozzles a recess or by-pass extending from the
liquor inlet in the plug of the cock to the air-port or opening in the said plug.
To enable my invention to be fully understood I will describe how it can be
carried out in practice by reference to the accompanying drawing, in which :-
Figure 1 is a vertical section of a cock for racking off wines and other liquors
embodying my present improvements, the cock being shewn closed:
Figure 2 is a similar view but shewing the cock open:
1
Figures 3 and 4 are horizontal sections on the lines A B and C D respectively of
Figure 1.
Similar lettore in all the figures indicate similar parts.

page_text: a is the body of the cock; b and c the two nozzles for the inlet of the liquor
and outlet of the air respectively; d is the conical end to admit of the cock being
fixed in the bung hole or other opening of the cask or other vessel; f the plug of
the cock; the passage therein; and g the annular space between the plug and
the conical end d of the body of the cock, and h and i the liquor and air-inlet
ports or openings in the plug respectively all the said parts being arranged
according to the Specification of my said former Letters Patent.
jis the recess or by-pass which I now form in the body a of the cock opposite the
liquor-inlet nozzle and air-escape nozzle c, the said recess or by-pass extending
from the liquor inleth in the plugf of the cock to the air-port i.
By this construction when the cock is closed as shewn in Figure 1 the recess or
by-pass j establishes communication between the liquor-passage e of the cock and
the air-passage g thereof, so that as the cock is lifted from a cask or other vessel
the air may pass in at the bottom of the conical end d and through the by-pass j
into the passage e and thereby allow any liquid which would otherwise be held
suspended in the plug to flow out. When the cock is open as shewn in Figure 2
communication between the by-pass; and the air-port g is cut off. By this means
I avoid the delay and waste which usually take place in draining the down-
pipe.
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 of the kind herein referred to for racking off wines and other liquors
having a recess or by-pass formed in the body of the cock opposite to the liquid
and air-inlet and escape nozzles, such recess or by-pass extending from the liquor
inlet in the plug of the cock to the air-port in the said plug substantially as, and
for the purposes, herein set forth.
2. The improved cock for racking off wines and other liquors hereinbefore
described and illustrated in the accompanying drawing.
