Specification Accepted, 9th Mar., 1889
1, HERBERT JOHN ALLISON, of 52 Chancery Lane, London, in the County of
Middlesex, Patent Agent, do hereby declare the nature of this invention (which
has been communicated to me from abroad by Levi Franklin Smith, of No. 2430
Thompson Street, in the City of Philadelphia, State of Pennsylvania, United States
of America, Manufacturer), and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement :-
Figure 1, is a central section through my stop-valve bung. Figure 2 is a face
view thereof, the top being removed. Figure 3 is a detail sectional view showing the
valve depressing devices. Figure 4 and figure 5 are detail views of the valve.
This invention is an improved valved bung for tanks containing fermenting liquors,
and its objects are to provide a combined stop valve, and air valve, bung, and to
provide means wheroby the valve may be held open during the filling of the vessel
and afterwards hermetically closed, and to these ends the bung is constructed and
arranged as hereinafter fully described.
In the drawings, A represents a portion of a vessel in the bung hole of which is an
annular flanged bushing B, screw-threaded exteriorily to engage the sides of the bung
hole, and interiorily for engagement of my improved bung. The said bung has a
cylindrical outer shell D flanged at its outer end, as at d, and exteriorily throaded
at c, near said flange, to engage bushing B, as shown. The inner end of shell D is an
annular interiorily threaded ring E, connected to the body of the shell by legs c.
The outer end of the shell is threaded interiorily at f, and within said threaded portion
is a partition G formed integral with the shell and having an opening g at one side.
Outside said partition G are a series of lugs F, projecting inward from the wall of the
shell, and adapted to be engaged by a wrench when it is desired to remove or replace
the bung.
To the inside of partition Gis fitted a ring H the edge of which is dressed to form
a seat for the valve I. Said valve is dressed on its face to fit against seat H, and it
moves within arms e, being mounted on a stem J the outer end of which passes

page_text: through an opening in partition G, and its rear end through an opening in a
disk K secured within ring E, by means of threads, or in other convenient manner,
preferably threads, as shown, so that the disk and valve can be removed if it becomes
necessary to redress the latter.
The stem lies in the axial line of the shell, and the valve is automatically closed by
a spiral conical spring I placed between the valve and disk K. The end of stem J
passing through partition is threaded exteriorily and bored interiorily as at j, said
oro passes through the stem from its outer end to a point below the valve, and is
shouldered at m above the valvo, and threaded above said shoulder. M is a scrow
plug in the threaded end of borej and when scrowed home its inner end will seat on
shoulder in and close the bore. N is a lateral opening in the stem communicating
with borej above tho valve, and n is a similar oponing communicating with bore j
below the valve.
O is a nut on the end of stem J above partition G, which when screwed down locks
the valve on its seat, the enlarged head of plug M prevents nut ( being turned off the
stem. As the metal fuces of the valve and its seat wear and sometimes prevent close
joints, may employ a flexible disk (, as shown in figures 4 and 5, which in the
former instance is placed on the front face of the valve, and is properly retained by a
plate and nut, when the valve is seated the edges of disk are bound between the
valve and its seat ensuring a tight joint. As shown in figure 5, the Hexible disk is on
the back of the valve, and whin the latter is closed, the pressure of fluid or gases
presses the flexible edges of the disk against the face of seat H ensuring tight joints.
P is a slot in partition to one side of oponing i, and Q is a key or flat bar of
metal provided with opposite notches y, on its sides. R is a metal cap bnving a
threaded flanger, adapted to engage threads fof the shell as shown. This cap may
be attached to the bang or vessel by a chain, to prevent its loss.
Bushing B being secured in the bung-hole, the bung is screwed therein, the valve
being kept closed by its spring. When it is desired to fill the cask, key Q is inserted
through opening Pand the valve depressed thereby, the key is then turned and its
notches engage the lower edges of said slot locking the key and holding the valve
open. The supply tube is passed through opening between arms into the vossal.
When filled the tube is withdrawn, key Q removed, and the valve is immediately and
automatically closed. If the vessel is to be transported nut Ois_scrowed down
against partition G locking the valve, and cap R is put in place. To admit air to
the vessel without opening valve 1, plug M is partly unscrewed until communication
is established between opening N and boro j, when air can pass through the bore into
the vessel.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
1. In a stop valve bung, the combination of the cylindrical shell having a somi-
annular partition and annular valve sent at one ond; with a valve, a valve stem
carrying said valve having one end playing through an opening in said partition and
screw-threaded, and its other end playing through a disk in the lower end of the
shell, a coiled spring for oporating said valve, and tho nut on the threaded end of the
stem, substantially as described.
2. The combination of the shell, its valvo seat and valve having a stem bored
longitudinally to establish communication through the valve when the latter is closed
and having lateral openings communicating with the bore at opposite sides of the
valvo; with a screw plug M for closing said bore and cutting off communication
therethrough, substantially as specified.
3. The combination of a shell having an annular valve seat, and a spring actunted
valve; with a valve stem having a central boro and openings communicating thoro-
with on opposite sides of the valvo, a scrow plug in the outer end of said stem for
closing communication through its bore, and a nut on said stem for locking tho valvo,
all substantially as described.

page_text: 4. The combination of the shell having an internal partition G provided with a
slot P and the valve and valve stem; with a key Qadapted to be inserted through
slot P to depress the valve and retain the same open, all substantially as specified.
5. In a bung, the combination of shell D having an internal partition G, an annular
valve seat below said partition, and an interiorily threaded ring E at its opposite end,
with the valve I, valve stem J, nut O, disk K exteriorily screw-threaded, and
spring L, all substantially as specified.
6. The combination of the flanged exteriorily and interiorily threaded bushing B;
with the stop valve bung having an exteriorily threaded portion engaging said
bushing, and a perforated partition G, valve seat HI, spring actuated valve I its stem J
having borej and openings N, n, the nut O and plug M, all substantially as described.
7. The herein described stop valve bung, consisting of a cylindrical exteriorily
threaded shell formed with a transverse perforated partition near its outer end, and an
annular valve seat at the inner side of said partition; in combination with a valve
stem J carrying a valve I and playing through a central oponing in said partition and
through an opening in a disk K secured in the inner end of the shell, the conical
spring controlling said valve, and the nut on the end of the stem outside said
partition, substantially as set forth.
