All improved Automatically closing тар поте valve and vent
Valve for Casks and Barrels.
We, JOHN GILMORE, of the Vicarage, West Norwood, in the County of Surrey,
Clerk in Holy Orders, JOHN FARQUHAR GILMORE, of the same place, Merchant, and
WILLIAM RICHARD CLARK, of 3 Danby Street, Peckham, in the County of Surrey,
Mechanician, do hereby declare the nature of this invention to be as follows:-
Our invention relates to an improved automatically closing tap and spigot or vent
valve to be employed therewith to be used for barrels & casks, and it is designed to
keep the interior of the barrel free from contact with the outer air upon the removal of
the tap and to prevent the liquor spurting out and wasting when the tap is inserted or
removed.
A great difficulty and expense, attendant on the use of beer barrels, is that they
require to be cleansed of the remnant of beer, which by contact with the atmosphere
has become sour.
Now by our invention such contact is avoided, and the barrel may be filled without
the necessity of bringing any water or steam in contact with the same.
Our invention consists of a valve spring pressed against a seating in the interior of
the barrel, the pressure being sufficient to hold the valve against the weight or pressure
of the liquid. The interior of the back of the valve is formed with a female screw-
thread, and the whole is screwed on to a socket into which the butt of the tap fits.
This socket is flush, or nearly so, with the end of the barrel.
The butt of the tap is formed with a screw thread to correspond with the female
screw in the valve, and, upon being inserted in the socket, it engages therewith, and
the shoulder or flange resting against the socket plate, and rotation being imparted to
the tap, the valve is drawn against the spring pressure from its seating by the travel
of the screw, and the tap is held firm by the screw and the reaction of the spring.
The beer is then free to travel round the edges of the valve and through the tap,
which is fitted with a cock in the usual way.
It is obvious that the conditions may be reversed, when the tap is screwed through
the socket plate, and raises the valve against the pressure of the spring and the liquor.

page_text: For our spigot or vent valve, we provide a valve fitting upon a suitable seating in a
recess and spring pressed thereupon so as to be normally closed. To a projection
formed on the back of this valve is pivotted a cam which when it lies upon its side
allows the valve to rest upon its seating, but upon being raised erect presses upon a
frame and raises the valve from the seating, thus admitting as much air as may be
required to restore atmospheric equilibrium, when the beer is withdrawn from the
cask.
The cam being erect and the barrel rolled, it will catch in the ground and fall into
its recess, closing the valve, and not interfering with the handling of the barrel.

An Improved Automatically Closing Tap-hole Valve and Vent
Valve for Casks and Barrels.
We JOHN GILMORE of the Vicarage West Norwood in the County of Surrey,
Clerk in Holy Orders, JOHN FARQUHAR GILMORE of the same place Merchant, and
WILLIAM RICHARD CLARK, of 3 Danby Street Peckham in the County of Surrey
Mechanician 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:-
Our invention relates to an improved automatically closing tap and spigot or vent
valve, to be employed therewith when used for barrels or casks, and it is designed to keep
the contents of the barrel or cask free from contact with the outer air, upon the removal
of the tap, and to prevent the liquor spurting out and wasting when the tap is inserted
or removed A great difficulty and expense attendant on the use of barrels is that
they require to be cleansed of the remnant of the beer which has been left in the
barrel and which by contact with the atmosphere has become sour.
Now by our
invention such contact is avoided, and the barrel may be refilled without the necessity
of the use of much water or steaming the barrel to purify it from the effect of the
sour beer left in it.
Our invention (fig. 1) consists of a valve, A, spring pressed against a seating, B,
in the interior of the barrel at the tap hole, the pressure being sufficient to hold the valve
against the weight or pressure of the liquid, the interior of the back of the valve is
formed with a female screw thread and the whole is screwed on to a socket C into
which the butt of the tap D fits. This socket is flush or nearly so with the end of the
barrel, the butt D of the tap is provided with a screw thread to correspond with the
female screw in the valve, and upon being inserted in the socket it engages therewith,
and the shoulder flange resting against the socket plate C, and rotation being imparted
to the tap the valve is drawn against the strong pressure H, H, from its seating, by
the travel of the screw & the tap is held firm by the screw and the reaction of the
spring H, H, the beer is then free to travel round the edges of the valve and through
the tap which is fitted with a cock in the usual way.
It is obvious that the conditions may be reversed, when the tap being thro'
the socket plate C, a projection I presses against the valve A, overcomes the pressure
of the spring H, and the liquor is then free to be drawn from the tap.
The tap D (fig. 3) is screwed on to a projecting tube which is driven or screwed
onto the end of the barrel with a projecting pin I as the tap screws in it presses the
valve away from its seating and allows the liquid to flow.
Fig. II shews valve open by the tap being screwed in-fig. I shews it closed-
fig. IV. back view.
In our spigot valve we provide a valve fitting upon a suitable seating in a recess
and spring pressed thereon, so as to be normally closed fig. V-and open in fig. VI-

page_text: the top view in fig. VII. A projection P formed on the back of the valve is pivotted
and forms a cam, when this cam lies on its side it allows the valve to rest upon its
scating but when it is raised erect it presses upon a frame F and raises the valve from
the seating thus admitting as much air as may be required to restore atmospheric
equilibrium when the beer is being withdrawn from the cask.
The cam if erect, and thus the valve open, will when the barrel is rolled over catch
on the ground and by the weight of the barrel be pressed into its recess, and the valve
thus be closed. The cam is ordinarily closed by hand pressure.
Having now particularly described and ascertained the nature of our invention and
in what manner the same is to be performed, we declare that what we claim is
I. The combination of a tap and valve so that when the tap is screwed onto the
chamber in which the valve rests, the valve is opened by being drawn forward by the
rotation of the tap as shewn in figs. I & II.
II. We claim also the reverse action of this, so that screwing in the tap, then by the
pressure of a pin the valve is pressed backward and opened as shewn in fig. III.
III. We claim in combination with the automatic tap hole valve, a self closing vent
valve, which is normally closed and is opened by raising the cam which controls it as
shown in fig. V. VI. & VII. and which is self closed when the barrel is rolled over
upon being removed.
