VENT PEG ADAPTED FOR PURIFYING THE AIR ADMITTED TO FERMENTABLE LIQUIDS
Year: 1884

page_text: Fermentable Liquids.
I, WILLIAM HENRY HALL of 20 Combedale Road, Westcombe Park, East
Greenwich in the County of Kent, Boilermaker's helper do hereby declare the
nature of my invention for "VENT PEG ADAPTED FOR PURIFYING THE AIR
ADMITTED TO FERMENTABLE LIQUIDS" to be as follows:-
My Invention relates to the purifying of the air admitted through the vent
to casks or closed receptacles containing beer or other liquids liable to be decom-
posed by the impurities in the air, and it has reference to the employment over
the air inlet or vent, of a funnel or vessel containing filtering media through
which the air is caused to pass to the interior of the cask or closed receptacle.
The funnel is provided with a pipe which enters the cask, and this pipe is also
carried up within the funnel to a suitable height so as to form round it an annular
chamber which is partly filled with water; and over the mouth of the pipe is
placed a bell or inverted vessel dipping in the water of the funnel. It will be
obvious that when the tap is turned for drawing off the beer or other liquid, air
enters at the upper part of the funnel passing by a circuitous course through the
water and beneath the bell to the pipe whence it enters the cask or closed
receptacle in a purified condition, the result being that beer or similar liquid is
preserved in good condition for a much longer period than is practicable when the
ordinary vent pegs are used.
In lieu of employing water in the funnel, any other suitable liquid such for
example as salycilic, carbolic or sulphuric acid may be used, with or without the
addition of pumice stone or similar aubstances.
The apparatus also forms a tell-tale, by audibly indicating when the beer or
other liquid is being drawn off, through the noise produced by the bubbling of the
air through the water,

I, WILLIAM HENRY HALL of 20 Combodale Road, Westcombe Park, East
Greenwich in the county of Kent, Boiler makers helper do hereby declare the
nature of my invention for A VENT PEC ADAPTED FOR PURIFYING THE AIR
ADMITTED TO FERMENTABLE LIQUIDS 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 tho, purifying the air admitted through the vent to
casks or closed receptacles containing beer or other liquids liable to be decomposed
by the impurities in the air, and it has reference to the employment over the air
inlet or vent, of a funnel or vessel containing filtering media through which air is
caused to pass, to the interior of the cask or closed receptacle. The funnel is
provided with a pipe which enters the cask, and this pipe is also carried up within
the funnel to a suitable height so as to form round it an annular chamber which is
partly filled with water; and over the mouth of the pipe is placed a bell or inverted
vessel dipping in the water of the funnel. It will be obvious that when the tap
is turned for drawing off the beer or other liquid, air enters at the upper part of
the funnel passing by a circuitous course through the water and beneath the bell
to the pipe whence it enters the cask or closed receptacle in a purified condition,
the result being that beer or similar liquid is preserved in good condition for a
much longer period than is practicable when the ordinary vent pegs are used.
In lieu of employing water in the funnel, any other suitable liquid such for
example as salycilic, carbolic, or sulphuric acid may be used, with or without the
addition of pumice stone or similar substances or the funnel or vessel may be
covered with flannel or wool or other like filtering material or it may be replace l
by a porous plug made of carbon, clay or similar substances impregnated or not
with disinfectants.
The apparatus may also form a tell tale by audibly indicating when the beer or
other liquid is being drawn off through the noiso produced by the bubbling of the
air through the water.
Having now particularly described & 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 purification of the air admitted through the vent to casks or closed receptacles
containing beer or other liquids liable to be decomposed by the impurities in the
air substantially as in the manner heretofore described.
Dated this second day of July 1885.
