PROVISIONAL SPECIFICATION.
Improved Appliance for Sealing and to Facilitate the Tapping or
Opening of Drums, Barrels, Fire-extinguishers, or other Receptacles
containing Acids, Beer, or other Liquors.
I, ALFRED WILLIAM PEMBERTON of Blackfriars Street, Salford in the County.
of Lancaster, Cotton Spinner, do hereby declare the nature of this invention to be
as follows:
The object of this invention is to provide an appliance wherewith drums, barrels,
casks or other receptacles for containing liquors may be readily hermetically sealed
and easily tapped or opened when required to withdraw the liquid.
Into the receptacle is fitted or screwed a hollow boss or sleeve screwed internally
and provided with a seating upon which rests a disc or diaphragm of lead or other
material frangible or easily cut. Upon the disc is screwed down a second hollow
boss or sleeve also internally screwed, which holds the disc firmly in position and
seals the opening into the interior. Into this second hollow boss or sleeve screws a
tap, tube, pipe, union or other device for drawing off the liquor or for attaching
a pipe or pump thereto. This tap is fitted with a cutter or other device which when
screwed against the sealing disc cuts or breaks it thereby allowing the contents to
flow through. The tap may be open at the end or closed and formed with perfora-
tions as desired.
When refilled the receptacle is again easily sealed by withdrawing the second
hollow boss or sleeve and inserting another disc on the seating and screwing it in
tightly again.
The appliance may be attached to oil or acid drums, small hand grenades or fire
extinguishers from which the liquor is thrown without the aid of a pump, beer
barrels, casks and other receptacles for liquid which require to be hermetically
sealed but easy to open.

COMPLETE SPECIFICATION.
Improved Appliance for Sealing and to Facilitate the Tapping or
Opening of Drums, Barrels, Fire-extinguishers, or other Receptacles
containing Acids, Beer, or other Liquors.
I, ALFRED WILLIAM PEMBERTON, of Blackfriars Street, Salford in the County
of Lancaster, Cotton Spinner, 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:—
The object of this invention is to provide an appliance wherewith barrels, casks,
hand fire extinguishers drums or other receptacles for containing liquors may be
readily hermetically sealed and easily tapped or opened when required to withdraw
the liquid.
It consists essentially of a hollow bush or sleeve screwed internally with a seating
upon which rests a disc or diaphragm of lead or other material and an inner sleeve
also screwed internally which is screwed down upon and holds the lead disc in
position thereby sealing the opening into the interior.
The invention will be fully described by reference to the annexed drawings in
which as examples it is shown applied to the tap hole of a barrel or cask and to a
hand fire extinguisher.

page_text: Fig. 2, section of the appliance on line x-x.
Fig. 3, plan.
Fig. 4, sectional elevation of hand fire extinguishing apparatus.
Fig. 5, section of the appliance on line y-y.
In the several figures similar letters refer to like parts.
Into an aperture A such as a tap hole or other opening for drawing off or
emptying the liquor is fitted or screwed a hollow bush or sleeve B made of any
suitable metal. The bush or sleeve B is cut or provided internally with a screw
thread and at one end of it is formed a seating b upon which I place a disc or
diaphragm C of sheet lead or other material readily frangible or easily cut. Into
the interior of the sleeve B is screwed a second sleeve or hollow bush D which
bears against and holds the sealing dise C firmly in position. When the sleeve D
is screwed down the leaden disc Chermetically seals the aperture into the interior
of the receptacle. The seal is opened or broken by the insertion of a hollow plug,
tap, tube or other device into the interior of the sleeve D which when forced
against the sealing disc cuts it or punches it out round the seating. The sleeve D
is preferably provided with an internal screw thread and the hollow plug or tap
formed with a corresponding thread.
In Figs. 1, 2 and 3 it is shown applied to an ordinary cask or barrel the
sleeve B being fitted into the tap hole and secured thereto. The tap E which is of
any ordinary construction is formed with a screw thread on the shank corresponding
with the screw on the inner sleeve D. The shank of the tap may be either open or
closed at the end with suitable perforations. To tap the barrel it is screwed into
the sleeve the end punches out the disc C and passes through into the interior
when the barrel is empty the tap is withdrawn and applied to another barrel.
In Figs. 4 and 5 the invention is shown applied to a small tubular fire extinguisher
or hand grenade from which a still liquor is thrown on to the fire without the aid of
a pump. The sleeve B is soldered or otherwise attached to the end of the tube or
receptacle F which holds the extinguishing liquid. Into the interior of the inner
sleeve D is screwed a hollow plug & which is forced against the sealing disc C. It
is milled round the outer edge and provided with projecting pieces or wings g by
which a firm grip may be obtained to screw it into the sleeve D against the disc C.
The outer end may be open or is preferably as shown provided with a perforated
rose or cover gl. When required for use the hollow plug G is screwed down
against the seal, the disc cut and the liquor discharged through the perforations
in the rose or cover g¹. At the other end of the extinguisher I place a small air
valve H which falls to its seat when in an erect position but which falls away and
allows the entry of air when the apparatus is being discharged. The vent may be
covered by a small screwed cap H when not in use to prevent dust or dirt lodging
thereon or any drip or leakage therefrom.
The appliance may also be attached to receptacles other than those illustrated
such as oil or acid drums or the like for holding liquids which require to be
hermetically scaled but easy to open.
At any time or when re-filled the receptacle can again be easily sealed. The
inner sleeve D is unscrewed and the remains of the first disc withdrawn a fresh
disc is inserted and placed on the seating band the sleeve again screwed down
thereon.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed I declare that
what I claim is :-
1. An appliance whereby barrels, casks, fire extinguishers, drums, and other
receptacles for liquids may be readily sealed and easily tapped consisting of a hollow
bush or sleeve to be attached thereto with a seating to receive a disc or diaphragm
a small sealing disc of lead or other soft frangible material and an inner hollow
sleeve to retain the sealing disc in position substantially as described.

page_text: 2. The combination with a barrel, cask, fire extinguisher oil drum or other
receptacle for liquids of an internally screwed hollow bush or sleeve to receive a
sealing disc attached to the receptacle an internally screwed bush or sleeve fitting
into the other to secure. the sealing disc in position and a hollow plug, tap or the
like screwed into the inner sleeve to break the seal and discharge the contents
substantially as described and shown.
