Improvements relating to Bungs for Casks, Tanks, and the like.
I, JOHN DAY, 11, Meadow Street, St. Paul's Road, Southsea, by trade an
Engineer, JOSHUA HART, Cork Manufacturer, 13, Lake Road, Landport, Ports-
mouth, do hereby declare the nature of this invention to be as follows:-
Improvements relating to bungs for casks, tanks and the like for use in closing
the orifices or bung holes in casks or tanks & other vessels & are made of iron
or metal or other suitable materials & are designed to supersede the ordinary
bushes & plugs now in use especially in the brewing business. The bushes &
plugs are constructed so as to obviate the use of corks or wooden shives vent
spills &c. They are fitted into the casks or vessels the same as the ordinary ones
now in use, either by being screwed in or rivetted through the flanges. The tight
joints are made by the surfaces of the plugs and bushes being pressed in contact
with each other, or by the insertion of an india-rubber washer or other suitable
material & are pressed together either by a cam or wedge system or by what might
be termed a cam lever or spring which secures the plugs in the bushes making
them tight. The plugs are made either with a vent hole in the centre or not,
as required, also with a valve in the centre or without one. The plugs with valves
are intended for use in cellars, or when the liquid is drawn by means of pumps
or the ordinary beer engines.

Improvements relating to Bungs for Casks, Tanks and the like.
JOHN DAY, 11, Meadow Street, St. Paul's Road, Southsea, Trade Engineer,
jointly with JoSHUA HART, 13, Lake Road, Landport, Portsmouth, Cork Manu-
facturer, 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:-
Improvements relating to bungs for casks, tanks and the like, and are made
either of iron metal or other suitable material. They are intended to obviate
the use of corks or wooden shives, spills &c. and are fixed into the casks, tanks
or other vessels, either by being screwed in or secured through the flanges by

page_text: rivets or other suitable means.
The bungs or plugs have a washer of india rubber
or other suitable material in a recess as shown at R Fig. 5 and the bushes have
a corresponding projection shown at S Fig. 3 which fits the recess in bung or
plug, and are forced in contact with each other either by a key or lever making
the junction air tight &c.
Fig. 1. Plan of bung or bush together with plug and key or lever complete.
Fig. 2. Bush in elevation and shewing the recess at H to receive key or lever
Fig 6, and which is held down and secured by turning thumb piece at I.
Fig. 3.-Section of bung or bush together with plug, key, or lever, spring, and
valve complete, with arms of plug Fig. 4 and lever Fig. 6 in position to be pressed
down into the recess at H
Fig 4. Plan of plug shewing radial recesses on arms of plug as at J into
which the fulcrums of Fig. 6 are placed and which are the bearings for K.
Fig. 5. Section of plug shewing spring at M, keep pin and disc at G, vent hole
in plug at P, ball valve of indiarubber or any suitable material at L india rubber
washer at R.
Fig. 6. Key or lever side elevation shewing fulcrum at K.
Fig. 7 Disc with hole in centre, and is placed between keep pin G and
lower end of spring in Fig. 5.
Fig. 8. Keep pin shewn at G in Fig. 5.
The mode of application in using these bungs &c. is as follows:-
The bush or bung Fig. 1 is permanently fixed into the cask or tank. The
plug Fig. 4 is dropped into the bush or bung as at S. The ends or fulcrums of the
key Fig. 6 are placed in the radial recesses of plug at J, which is given a quarter
of a turn which brings the arms of plug Fig. 4, and the fulcrums of the key or
lever Fig. 6 under the flanges of the bush as shewn at C in Fig. 3, when the
lever may be pressed down into the recess shewn at H in Figure 2, and secured by
turning thumb piece I in the position shewn in Figure 1 plan A when it is
secured &c.
These bushes and plugs will also be secured in position in other ways and
patterns as required namely by means of a wedge or cam system. They have a
wedge piece or cam on the ends of the arms of the plug instead of a radial recesses
as shewn at J Fig. 4, and with a corresponding wedge or cam under the flange
at T Fig. 1 or on the bottom part of the bush, so that when the plug Fig. 4 is
dropped into the bush Fig. 1, and given a quarter of a turn more or less, the
wedges or cams are forced together with key or wrench making the junction air
tight &c.
The plugs are made with vent hole and valve in the centre or not as required.
The plugs with valves are intended for use in cellars, or when the liquid is drawn
by a pump or the ordinary beer engine, admitting the air only as required.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what
we claim is:-
The production of a bung and plug that can be 'made air tight without the aid
of a screw thread on the plug, or in the bush or bung.
