PROVISIONAL, SPECIFICATION.
Improvement in Venting Casks or Barrels.
I JOHN ENOS DUDLEY Gas Fitter, 15 Plato Street, Oldham, do hereby declare
the nature of this invention to be as follows:-
Fig. 1. is part section of a shell or casing and rotating plug as described in my
Complete Specifications and drawings Fig. 7, of my patent tapping arrangement
for casks or barrels and numbered 20,209, 1889.
(A) is a short slot or grove which is cut in the side of the rotating plug (B) to
engage with a hole (C) in the shell or casing to vent the cask. (C) is a hole in
the shell or casing and engages with the slot or grove (A) in the side of the
rotating plug (B) for the purpose of supplying air, or venting the cask or barrel
when a supply of beer, &c., is being drawn from the barrel.
Figs. 2, & 3 are part elevations of Fig. 12, of my Complete Specifications and
drawings as before mentioned and numbered 20,209, 1889.
Fig. 2 shows the end of the slot or grove (A) which is cut in the side of the
plug (B) engaged with the vent hole (C) open, to supply air, or vent the barrel
while the plug is open. (D) is a projecting piece on the head of the plug for the
purpose of partial rotating the same by a key provided for that purpose, and
described in my Specifications and drawings as before mentioned and numbered
20,209, 1889.
On moving the plug round in the direction of the arrow and towards the
word (OFF) as shewn in Fig. 3. the supply of beer, &c. from the barrel is shut
off, and also the supply of air, or vent, at the same time, immediately the plug is
turned in the direction of the arrow the vent is closed, as the slot or grove (A)
in the side of the plug disengages from the vent hole (C).
By this method of venting casks or barrels it is impossible to open the tap to
get a supply of beer, &c., without venting the cask at the same time, conversely
is it so in stopping the supply of beer, &c., the vent being closed at the same time.
When applied to barrels where the beer, &c., is drawn without pumps, it will
be found invaluable, especially so in domestic use, as the old method of venting
on the side of the barrel by a seperate arrangement, and the fear of leaving the
vent open, and the beer, &c., spoiling is entirely obviated by my venting arrange-
ment working in conjunction with my patent tapping arrangement.
When the barrels have to be connected with pipes to beer pumps, and the tap,
and vent left open to allow the beer to be drawn by the pumps from the barrel,
a small clack or valve can be applied as shewn at (E) to prevent the air from
entering the barrel only when the beer, &c., is being drawn out, when the clack
or valve will lift and allow the air to pass, by screwing out the air tube, or vent
tube (F) the small clack or valve may be put in, or taken out, but should only be
put in when the barrel has to be connected with pipes to beer pumps, or other
pumps. The vent tube (F) is diverted into the barrel so as to supply air, or.
vent the barrel above the surface of the bear, &c., when the barrel is placed on
its side.

Improvement in Venting Casks or Barrels.
I JOHN ENOS DUDLEY Gas Fitter, 15 Plato Street, Oldham, 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 :-
Fig. 1. is part section of a shell or casing and rotating plug as described in my
Complete Specifications and drawings Fig. 7. of my patent tapping arrangement for
casks or barrels and numbered 20,209, 1889.
(A) is a short slot or grove which is cut in the side of the rotating plug (B)
to engage with a hole (C) in the shell or casing, to vent the cask. (C) is a hole
in the shell or casing and engages with the slot or grove (A) in the side of the
rotating plug (B) for the purpose of supplying air, or venting the cask or barrel
when a supply of beer &c. is being drawn from the barrel.
Figs. 2. & 3. are part elevations of Fig. 12. of my Complete Specifications and
drawings as before mentioned and numbered 20,209, 1889.
Fig. 2. shows the end of the slot or grove (A) which is cut in the side of the
plug (B) engaged with the vent hole (C) open, to supply air, or vent the barrel
while the plug is open. (D) is a projecting piece on the head of the plug for
the purpose of partial rotating the same by a key provided for that purpose,
and described in my Specifications and drawings as before mentioned and
numbered 20,209, 1889.
On moving the plug round in the direction of the arrow and towards the
word (OFF) as shown in Fig. 3. the supply of beer &c. from the barrel is shut
off, and also the supply of air or vent, at the same time, immediately the plug is
turned in the direction of the arrow the vent is closed, as the slot or grove (A) in
the side of the plug disengages from the vent hole (C).
By this method of venting casks or barrels it is impossible to open the tap to
get a supply of beer &c. without venting the cask at the same time, conversely
is it so in stopping the supply of beer, &c., the vent being closed at the same time.
When applied to barrels where the beer &c. is drawn without pumps, it will be
found invaluable, especially so in domestic use, as the old method of venting on
the side of the barrel by a seperate arrangement, and the fear of leaving the vent
open, and the beer &c. spoiling is entirely obviated by my venting arrangement
working in conjunction with my patent tapping arrangement.
When the barrels have to be connected with pipes to beer pumps, and the tap
and vent left open, to allow the beer to be drawn by the pumps from the barrel,
the air passage as shown at (E) is enlarged to admit a small ball which is also
shown at (E) the said ball on seating itself on the top of the vent hole (C) will
prevent the admittance of air into the barrel when the pumps are not in use by
the pressure from the beer &c. forcing the ball on the seat. Immediately on
pumping beer &c. from the barrel the said ball will lift and allow the air to pass
to vent the barrel By screwing out the air tube, or vent tube (F) the said ball
be put in, or taken out, but should only be put in or used when the barrel has
to be connected with pipes to beer pumps, or other pumps. The vent tube (F)
is diverted into the barrel so as to supply air or vent the barrel above the surface
of the beer &c. when the barrel is placed on its side.

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,
The particular method of automatically venting a cask or barrel by the action
of the thuh

page_text: a hole in the shell or casing in which the plug fits and allows a current of air to
pass into the barrel, on turning the plug to stop the supply, the vent is closed at
the same time, substantially as herein before described and illustrated in Figures 1,
2, & 3 of the drawings left with the Provisional Specification.
Dated this 24th day of October 1891.
