Improvements in Tapping Devices for Casks and like Receptacles.
I, GEORGE GABB of 47 Kingston Road, Wimbledon, in the County of
Surrey, Wine Merchant, do hereby declare the nature of this invention to be as
follows:-
My invention is designed so as to improve the so-called broaching taps now in
use and particularly to obviate the necessity of using spiral or other springs for
the purpose of keeping a valve up to its seating within the metallic cylinder
permanently fixed to the cask or other receptacle and to make the device a lock
to the cask or receptacle the tap forming at the same time the key thereto.
In carrying out my invention I sink flush with the head or other part of the
cask a preferably circular flange or plate carrying a short cylinder or barrel pro-
jecting into the cask through and clear of the head thereof (or other portion to
which it is attached) so far as may be found convenient. At or near the centre of
the cylinder is an internal flange or projection shouldered on the inner face to
form the seating for a valve head. To the rear of this seating surrounding the
cylinder are perforations for the admission of the fluid contained in the receptacle.
The rear end of the cylinder is internally threaded to carry a cap which may be

also perforated, and is screwed to fit therein.
threaded to receive a screwed face plate or disc and the tap itself. The valvular
device is constructed as follows. I provide a metallic block or boss shouldered to
fit the seating and carrying a spindle projecting towards the front of the cylinder
and terminating in a left handed screw over which engages a shouldered cap or
nipple inserted through the face plate or disc hereafter described the nipple being
fluted to receive a screwdriver or the like. The face plate or disc carries a short
tube or chamber which surrounds one end of the valve spindle and is shouldered
internally at its extremity to stop the cap or nipple before described which fits
close up thereto and thereby keeps or pulls the valve (by the spindle to which it is
fitted) close up to its seating when the face plate or disc is flush with the front
plate on the withdrawal of the tap. The outer rim of the face plate or disc is
perforated to allow of the fluid in the receptacle passing into the tap when the
device is open for the purpose. In the face are two or more cuts or slots in which
engage correspondingly formed projections on the end of the tap. The edge or
rim of the face plate or disc is screwed to follow the thread of the front portion
of the cylinder and when engaged with the end of the tap by means of the pro-
jections thereon is run back until the end of its projecting tube comes in contact
with the valve head which is thus driven from its seating and the contents of the
receptacle allowed to pass through the face plate into the tap. On the withdrawal
of the tap by unscrewing the same the face plate or disc is brought forward again
flush to the front plate causing the valve head at the same time to return to
and press tightly against its seating and so the cask or receptacle is sealed or
locked.

Improvements in Tapping Devices for Casks and like Receptacles.
I, GEORGE GABB, of 47 Kingston Road, Wimbledon, in the County of Surrey,
Wine 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 is designed so as to improve the so-called broaching taps now in
general use and to obviate the necessity of using spiral or other springs for the
purpose of keeping the valve up to its seating within the metallic cylinder fixed
in the receptacle, moreover my improved device is also intended to act as a lock to
the receptacle, the tap portion acting as the key thereof.
+
Referring to the accompanying sheet of drawings,
Figure 1 is an elevation of the front of the device when closed and locked and
the tap removed.
Figure 2 is an end elevation of the tap showing the fangs or teeth forming
the key.
Figure 3 is a vertical longitudinal section of the cylinder and valve portions of
my device and
Figure 4 is a side elevation of the end of the tap showing one of the fangs or
teeth projecting from the screwed portion thereof.
In carrying out my invention I sink flush with the head or other part of the
cask or fix thereto a preferably circular flange or plate A carrying a short cylinder
or barrel B projecting into the cask through and clear of the head thereof (or
other portion to which it is attached) so far as may be found convenient. At or
near the centre of the cylinder is an internal flange or projection C shouldered on
the inner face to form the seating for a valve head D. To the rear of this seating
surrounding the cylinder are perforations for the admission of the fluid contained in
the receptacle.
The rear end of the cylinder is internally threaded as at E to carry a cap F
(which may be also perforated) which is screwed to fit therein. The front of the
cylinder is threaded as at G to receive a screwed face plate or disc H and the táp
itself. The valvular device is constructed as follows:
I provide a metallic head or boss D shouldered to fit the seating C and carrying
a spindle J projecting towards the front of the cylinder and terminating in a left
handed screw K over which engages a shouldered cap or nipple L inserted through
the face plate or disc H hereafter described, the nipple being fluted at L' to
receive a screwdriver or the like. The face plate or disc H carries a short tube
or chamber M which surrounds one end of the valve spindle and is shouldered
internally at its extremity to stop the cap or nipple before described which fits
close up thereto and thereby keeps or pulls the valve head (by the spindle to which
it is fitted) close up to its seating when the face plate or disc is flush with the front
plate on the withdrawal of the tap.
The outer rim of the face plate or disc is perforated as at H¹ to allow of
the fluid in the receptacle passing into the tap when the device is open for the
purpose. In the face are two or more cuts or slots N in which engage corre-
spondingly formed projections O on the end of the tap. The edge or rim of the
face plate or disc is screwed to follow the thread of the front portion of the
cylinder and when engaged with the end of the tap by means of the projections
thereon (or by a loose key) is run back until the end of its projecting tube comes
in contact with the valve bead which is thus driven from its seating and the
contents of the receptacle allowed to pass through the face plate into the tap. On
the withdrawal of the tap by unscrewing the same the face plate or disc is brought
forward again flush to the front plate causing the valve head at the same time to
return to and press tightly against its seating, and so the cask or receptacle is
sealed or locked.

page_text: For purposes of steaming or cleaning the face plate may be actuated by means
of a loose key.
Having now particularly described and ascertained the nature of my said
invention and iu what manner the same is to be performed I declare that what I
claim is
1. In broaching devices for casks and other receptacles the use of a valve head
such as D kept up to its seating by means of a spindle having a screwed end
engaging with a shouldered cap or nipple such as L. retained in position at the face
of the device by the face plate H and its chamber M, until released by the
insertion of the fangs or teeth O carried by the tap and the turning or screwing
of the said tap into the fore part of the cylinder B substantially as hereinbefore
described.
2. The locking or closing device for casks or like receptacles for liquids, such
device being capable of being released when the cask is full by means of the tap
before described, and when empty by the insertion of a loose key so that the cask
may be steamed or the device cleansed, substantially as hereinbefore described and
as illustrated by the accompanying drawings.
