Improvements in and relating to Bungs.
1, SAMUEL SALOMON of Market, 62 Labischin, kreis Schubin, in the Empire
of Germany, 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 :-
This improved bung closure is shown in the annexed drawing in Figs. 1 and 2 in
cross section in two different forms of construction, whilst Fig. 3 is a plan view
corresponding to Fig. 2.
In the construction shown in Figs. 2 and 3 there is placed in the bung hole a
conical plate socket A, which has on the top flange a whilst at the under part
a similar flange a' is obtained after having slid the socket into the bung hole, by
turning back the under edge with an appropriate tool. Into this metal socket is
driven the cork or bung E and a cover B is put on the flange a which cover
reaches with its curved projection b into a slot of the flange a and thus under the
latter so that the projection 6 forms a hinge joint; another projection 6² has the
small turnbuckle or lock c which forms on the upper part a key head c¹. This
turnbuckle reaches when standing rectangularly to the position of Fig. 3, through
a slot of the flange a and effects the closing connection between the cover B and
the bung socket when the head c is turned by a key. On the under side of
plate B is arranged a packing B' which presses upon the bung; between the two
surfaces there may be a disk of impervious material. By means of the rivet d the
disk D is fixed to turn on B which disk D is provided with two slots d'; in the
dotted position of Fig. 3 therefore the lock and the hinge joint are completely
covered by the disk D and protected against penetration of dirt. When the
closure is to be opened, the disk D is so turned, that the slots d' staud over the
closing device and hinge joint; from this disk a part is cut away at f in order
to allow the turning up of the cover. Instead of the disk represented there
might also be used a pivoted square bridge or also an eccentrically pivoted
completely circular disk.
In the form of construction shown in Fig. 1 there is no arrangement on
the one side of a hinge joint, but on each side there is arranged a turnbuckle
or lock.
It will be seen the closure is such that without using any bung E and only
by the tightening of the cover B against the border a a completely secure closing
is obtained.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
(1.) Improved bung closure consisting of a metal socket in the bung hole and
having above and below flanges extending over the eyes of the bung hole with a
cover which is fixed on one side with a hinge joint and on the other side by a
turubuckle or lock on the upper socket flange and on which cover is arranged
a rotary protecting plate, which usually covers the lock and the hinge joint.

page_text: (2.) A bung hole closure as in Claim 1 which is fixed by two turnbuckles or locks
in place of one hinge joint and one turnbuckle or lock.
