PROVISIONAL SPECIFICATION.
Improvements in Metallic Bungs.
We, EMILE REGNAC, GEORGES REGNAC and JULES REGNAC, of Charleroi,
Belgium, Brassfounders, do hereby declare the nature of this invention and in
which manner the same is to be performed to be as follows:-
The object of this invention is a metallic bung for barrels casks and tanks,
consisting in its essential parts of a metallic annular seat screwed with the threads
of its outer circumference into the bung-hole. To the top of this annular box is
provided an inwardly placed flange, the lower side of which having three or more
inclined planes, and into which box is put a solid disk having projections on the
outside, analogous and corresponding to the inclined planes of the seat; the
protuberant projections pass the slits given to the flange, if the disc is put into the
box and then by turning the wedge-shaped projections catch under the inclined
faces of the flange.
In the accompanying drawing, Fig. 1 is a transverse central section of the seat,
Fig. 4 a top plan-view of it; B are the inclined planes, CCC the slits provided
to put in the other part (D) drawn in Fig. 2, 5 and 3. The cylindrical body has
the projections (E) with inclined top faces; the inside of (D) is hexagonally shaped
in order to put in, after having set the box (D) into the seat (A), a screw-key by
turning of which the inclined faces of (E) are pressed against the correspondent
faces of (B).
In this manner a solid closing is reached the tightness of which is obtained by
the lute (H) put on the flange (C¹). In the center of (D) there is fixed (s. Fig. 2)
a ring affording an easy employment of the bung; in Fig. 3 the bung has in its
center a screw-down valve (J) the faying-surface of which is formed by the
ring (K) and by the lute fixed to the end of the screw-bolt (J). The center-nave
has two perforations (L) allowing an admission of air to the interior of the cask
the valve being screwed down.

We, EMILE REGNAC, GEORGES REGNAC and JULES REGNAC, of Charleroi,
Belgium, Brassfounders, do hereby declare the nature of this invention and in
which manner the same is to be performed to be as follows:-
The object of this invention is a metallic bung for barrels, casks and tanks-
The bang consists in its essential parts of a metallic annular seat screwed with the
threads of its outer circumference into the bung-hole. To the top of this annular
box is provided an inwardly placed slitted flange, the lower side of which having
two or more inclined planes, whilst the lower end of the box has a solid, inwardly
placed collar; into this box is put a disk having projections on the top, analogous

pass the slits given to the flange, if the disk is put into the box and then
by turning the wedge shaped projections catch under the inclined faces of the
flange, and the disk is pressed against the lower flange and the tightening hereby
effected.
In the accompanying drawings Fig. 1 is a transverse central section of the seat,
Fig. 4 a plan view of it; B are the inclined planes, CCC the slits provided
in the top flange to put in the other part D drawn in Fig. 2, 5 and 3. This
cylindrical body D is provided with projections E, having inclined top faces; the
inside of D is hexagonally shaped in order to put in, after having set the box D
into the seat A, a key by turning of which the inclined faces of E are press. 1
against the correspondent faces of B.
In this manner a solid closing is reached the tightness of which is obtained by
the late H put on the flange G. In the center of D there is fixed (see Fig. 2) a
ring affording an easy employment of the bung.
In Fig. 3 the bung has in its center a valve J, consisting of the set screw I to
the lower end of which is attached a metallic plate K', upon which is put a rubber
or leather lute K2; the nipple K³ having at its lower end an annular shape K, forms
the tightening face against which K2 is pressed if I is raised. The nipple has two
perforations L L, forming communications between the air and the inner of the
barrel; for drawing off the barrel the screw I is lowered, and hereby the tightening
of K and K suspended.
What we claim and desire to secure by Letters-Patent is:
1. A bung for barrels, consisting of an annular flat box, having a screwed outer
face whilst to the top of the inside is provided a slitted collar, the lower side of
which has inclined planes, whilst the lower end of the box has an inwardly placed
solid collar; and consisting of a polygonally hollowed disk the top of which has
projections with inclined planes, substantially as set forth.
2. In a bung as described the disk D, having in its center a valve, consisting of
a thumb-screw J placed in a center nave having perforations along its axis, whilst
to the lower end of the screw is fixed a tightening disk pressed by the screw
against a ring face, ceutrally arranged on the lower side of the disk, substantially
as set forth.
