A Cock for Charging Air and Liquor Combined into Stills and
other Vessels.
I, JOHN HARVEY of Dundas Hill Distillery, Port Dundas, in the County of Lanark,
North Britain, Distiller do hereby declare the nature of this invention to be as
follows:
:-
This Invention, which relates to a cock for charging air and liquor combined into
stills and other vessels, has for its object to admit air into such stills and other vessels
in advance of the liquor about such stills to be admitted thereinto and thereby to
prevent collapse of the stills or other vessels from the formation therein of a vacuum
through the condensation of steam; the passing of the air thereinto by the cock
constituting this Invention preventing such vacuum being formed.
The cock constituting this Invention has two passages in it one above the other and
at right angles to each other. These passages are so arranged that when the cock is
opened the liquor flows through one of the openings or passages into the still or other
vessel preceded by an air flow thereinto through the other passage, and on closing the
cock both the liquor and air passages are shut.

A Cock for Charging Air and Liquor Combined into Stills and
other Vessels.
I, JOHN HARVEY of Dundas Hill Distillery, Port Dundas, in the County of Lanark
North Britain, Distiller, 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, which relates to a cock for charging air and liquor combined into
stills and other vessels, has for its object to admit air into such stills and other vessels
in advance of liquor about to be admitted thereinto and thereby to prevent collapse of
the stills or other vessels from the formation therein of a vacuum through the con-
densation of steam; the passing of the air thereinto by the cock constituting this
Invention preventing such vacuum being formed.
The cock constituting this Invention has two passages in it one above the other and
at right angles to each other. These passages are so arranged that when the cock is
open the liquor flows through one of the openings or passages into the still or other
vessel preceded by a flow of air thereinto through the other passage, and on closing
the cock both the liquor and air passages are shut.
In order that my invention may be properly understood and readily carried into
effect I will now proceed to describe the drawings hereunto annexed.
Figure 1 is a side elevation of a cock constructed according to my invention.
Figure 2, is a plan of the same.
Figures 3 and 4 are respectively vertical sections of the same on the lines A. B.
and C. D. Figure 2.
Figures 5 and 6 are respectively sections on the lines E, F, and G. H. Figures 4
and 3.
The barrel or casing marked P of my improved cock as illustrated in the accom-
panying 3 sheets of drawings is constructed with 2 passages marked J and K being
the air and liquor passages respectively and are constructed at right angles to each
other and one above the other. A hollow plug marked L is secured in the barrel
marked P by a nut and screw at the lower part thereof as is usual in other kinds of
cocks. The plug L is provided with a horizontal division marked M at or near its
centre which divides the air passage marked J', situated in the upper part of the plug
marked L from the liquor passage K', in the lower part thereof.
When it is desired to apply my improved cock to stills for instance such as are
used in Distilleries the liquor passage K, is connected to the lower part of the still by
a pipe, the liquor passes through the cock in the direction indicated by the arrows
marked on the different figures. The air passage J, is also connected to the still by
means of a pipe so that when the cock is turned on for the admission of liquor to the

page_text: still air will simultaneously pass into the still through the passage J in the direction
of the arrows indicated more particularly in Figures 5 and 6 entering the still in
advance of the liquor thus preventing the collapse of the still or other vessel from the
formation therein of a vacuum through the condensation of steam.
Having now particularly described and ascertained the nature of my said Invention
and in what manner the same is to be performed I declare that what I claim is.
The improved cock for charging air and liquor combined into stills and other
vessels whereby air is or may be admitted in advance of or prior to the admission of
the liquor to such stills or vessels substantially as and for the purposes herein described
and shewn in the accompanying drawings.
