PROVISIONAL SPECIFICATION.
An Improved Tap for Beer-casks and the like.
I LOUISA GOODALL, of 7 Bartletts Buildings, Holborn, in the County of Middlesex,
Merchant, trading as H. A. Goodall & Co. (a communication to me from Alfred de
Coninck, of 33 Rue d'Hauteville, City of Paris, France, Merchant,) do hereby declare
the nature of this invention to be as follows:-
My invention relates to an improved tap for beer-casks and the like, and has for its
object to provide an air inlet in the tap itself, so that the use of vent-holes and pegs,
is obviated. In carrying my invention into practice, 1 form the valve or cock, by
which the liquid is turned on and off, with an additional perforation besides the one
which communicates with the barrel or stem of the tap. This said second perforation
is formed just above the first one, and communicates with a passage which terminates
in a groove, and which is formed down the tap, running parallel with the passage
through which the liquid flows.
"
In the perforation in the barrel or stem of the tap, through which the valve or cock
passes, a small groove is cut, so that when the tap is turned on, the groove in the valve
or cock, leading to the perforation in the top of the said valve or cock, is directly
opposite the groove in the barrel or stem of the tap, so that a passage is formed through
which the air and gas pass, through a passage cut for the purpose in the barrel or stem
of the tap, to and from the cask.

COMPLETE SPECIFICATION.
An Improved Tap for Beer-casks and the like.
I LOUISA GOODALL, of 7 Bartletts Buildings Holborn, in the County of Middlesex,
Merchant, trading as H. A. Goodall & Co. (a communication to me from Alfred de
Coninck, of 33 Rue d'Hauteville, City of Paris, France, Merchant,) 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 tap for drawing off
liquids from casks or barrels without requiring a vent hole, or having to remove the
bung from its opening.
The object of my invention is to provide a tap that will allow air to enter the barrel
or cask at the same time as a portion of its liquid contents are being drawn off.
In the accompanying drawings,
Fig. 1 is a longitudinal section of my improved tap, on the broken line x. x of Fig. 2
which is a sectional elevation of the same.
Fig. 3 is a horizontal section on the broken line Y. Y of Fig. 1.
Fig. 4 is a cross section on line z. z of Fig. 3, the plug being removed to show the
passages.
Fig. 5 represents the lower portion of the plug showing the air passage formed
therein.
P. is the plug and B the body of the tap. The inner end of this body is of ordinary
construction, its central passage or opening o leading to the two openings or perfora-
tions p. pl which open in the plug P as shown in Fig. 1. The perforation p forms an
air passage allowing, when the plug is turned on, air to enter from the outside into
the passage o, while the perforation p² allows at the same time the liquid from the cask
or barrel to pass through the tap and be discharged at its mouth m. The air passage a
LD077

page_text: in the plug P has the form of a vertical side groove (Fig. 5) leading at the top by
means of a small channel c to a round opening which communicates through the
body B with the air passage p and the passage o above mentioned, and thus enables
the outer air to reach the contents of the cask or barrel, this admission of air taking
place when the plug is turned on and its opening g communicates with the passage pl
and the passage o, that is to say, when liquid flows at m. This double influx of air
and discharge of liquid is due to the positions of the openings and 6. relatively to
that of the passages p. pl as when the plug P is turned off the communication
between the opening b and the passage p and between the opening g and the passage p¹
is closed.
my
Having now particularly described and ascertained the nature of said
invention and in what manner the same is to be performed, I declare that what
I claim is :-
My improved tap or cock allowing external air to reach the liquid contents of the
cask or barrel furnished therewith, at the same time as a portion of such contents is
discharged through its mouth, the said tap or cock being arranged, constructed and
operating, substantially as and for the purpose set forth.
