PROVISIONAL SPECIFICATION.
An Improved Method of Tapping Barrels Containing Beer, Porter,
or other Liquids, and Preventing Waste and Leakage of said
Liquids during Tapping.
. FRANCIS NUTTALL 13 Fisher Street Oldham in the County of Lancaster Black-
smith, do hereby declare the nature of this invention to be as follows:-
This Invention consists of an improved method of Tapping Barrels containing
Beer, Porter, or other Liquids, and for preventing waste and leakage of said liquids
during tapping, by means of a screwed bush or plug a, secured to the barrel end the
bush also carries a guide for the valve c and spring d, the valve being kept on the
seating e in the bush by means of the spring d and preventing the liquid from
escaping.
To tap the barrel I use a tapf screwed to suit the bush a the tap being provided
with holes as shewn at g Figs. 1 and 2, the tap is screwed into the bush until it
forces the valve c from its seating Fig. 2, the liquid then escapes through the holes y
in the tap, the said tap is arranged so that it is screwed in the bush a a short distance
Fig. 1 before coming in contact with the valve, so as to prevent leakage through the
bush before opening the valve.
When the tap is removed or unscrewed from the bush the spring d presses the
valve back to its seating before the threaded part of the tap leaves the bush.
I also provide the tap with a centre point h to engage in a corresponding recess in
the valve as shewn, to ensure easy and direct opening of the valve with little
friction and without damaging the face of the valve.

COMPLETE SPECIFICATION.
An Improved Method of Tapping Barrels Containing Beer, Porter,
or other Liquids, and Preventing Waste and Leakage of said
Liquids during Tapping.
FRANCIS NUTTALL, 13 Fisher Street Oldham in the County of Lancaster Black-
smith 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 :-
This invention consists of an improved method of tapping barrels containg Beer,
Porter or other liquids and for preventing waste and leakage of said liquids during
tapping.
By means of a bush or plug a Figs. 1, 3 and 5 secured to the barrel end the said
bush or plug having arms or projections; for guiding the valve c and spring d and
has also a screw thread to receive a tap f.
The bush has a valve seat e to receive valve c the said valve being kept against the
seat by means of the spring d and preventing the liquid from escaping.
To tap the barrel I use a tap f screwed to suit the bush a the tap being provided
with a hole or holes as shewn at g the tap is screwed into the bush until it forces the
valve from its seat, the liquid then escapes through the holes g in the tap, the tap is
arranged so that it is screwed into the bush a short distance before it commences to
open the valve, so as to prevent leakage through the bush, before the valve is opened,
the tap is also provided with a leather or rubber collar i, the face of the valve c may
also be provided with a similar facing of leather or other material, the valve casing or
projections are encircled by a gauze or strainer k to prevent hops or impurities

spring d presses the valve back to its seat before the threaded part of the tap leaves
the bush, Figs. 1 and 2 shew the arrangement secured to the barrel end on the inside
Figs. 3, 4, 5, and 6, shew the arrangenient secured to the barrel on the outside so that
the apparatus can be easily removed for cleaning both the valve and the barrel
Figs. 3 and 4 shew the more preferable plan, in this case I use another bush or
ferrule secured to the barrel end and screwed to suit the thread of the bush or valve
casing a, so that the valve can be taken out without much trouble.
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 :-
A method of plugging or securing the outlet of barrel by means of an arrangement
of bush or valve casing with valve and spring secured to barrel end in connection.
with a tap as shown and for the purpose as herein before set forth and more particularly
described in specification and drawings.
