This invention consists of a lid which has a movable part so connected thereto
that when the lid is pressed down, a prolongation of same is brought forward and
the lid fits in two opposite grooves.
The lower movable part of the lid is movably connected by hinges or pins to the
other part, and in the middle it is provided with a round upper projecting piece,
which goes through an opening in the upper part of the lid when same is shut
down. A metallic plate or disc of the same diameter as the said projecting piece is
placed on the said projecting piece so that it can revolve round an eccentrically
placed pin. If the plate or disc is turned back it is free to fall down, if on the
other hand the plate or disc is brought forward the movable part is joined tightly
to the upper part of the lid, so that they may be regarded as a single stiff lid.
If it is desired to lock the box with a lid of this kind, the latter is placed with
its middle part raised with one end in a groove formed in the end of the box and
the movable part being then pressed down, enters a groove formed in the other end
of the box. If the lid is now pressed down its ends will exactly fit into the
grooves, and the projecting piece with the plate or disc protrude through the

page_text: corresponding opening in the upper part of the lid. In order to fasten it securely,
the plate or disc is turned round its pivot whereby the plate or disc fits into a slot
formed in the end of the box. Now the removal of the lid from the.box is
impossible as long as the plate or disc remains in the slot. In order to fasten it
more securely, a string pin or padlock or bolt, may be put through a hole in the
projecting part of the plate or disc.
The box may according to a modification be provided with hook shaped pieces of
hoop-iron on two opposite sides, and the lid is movably fixed to two of them. On
the other end the lid is provided with the before described projecting piece and the
plate or disc movably fixed by its eccentrically placed pin. The mode of fastening
same is as follows. When the lid is put on the box a piece of wood is hooked by
pins at each end into the hooks formed at the ends of the hoop iron round the box,
and pressed down. The projecting piece with its eccentrically pivoted plate or disc
on the lid, then fill up the corresponding hole or opening in the before described
piece of wood, the plate or disc. is then turned round and projects through a slot
cut in a projecting side of the piece of wood and the locking is effected. In
reopening, it is necessary first to turn the plate or disc back on to the projecting
part, and then remove the piece of wood. In this case also the plate or disc is
made fast by a lock or pin or string through the hole near the edge thereof.
A further modification of this invention may be made as follows-Also in this
case the lid proper is provided with a projecting piece and an eccentrically pivoted
plate or disc. The lid is held in its position by two parts which are hinged near
each end of the box by means of hoop iron or in any other suitable manner, so that
there is room for the lid to go between them and the box.
The locking up is arranged in the following manner. These parts are raised so
as to allow the lid to be slipped underneath them on to the box, then they are put
down, and the projecting piece fits into the corresponding opening in the middle.
One of these parts overlaps the other. Then the plate or disc is turned round and
rests in a slot of a clamp on the part which overlaps, and a lock, string or pin may
be put through the hole of the plate or disc for holding it more securely. In order
to undo the lid, the plate or disc is drawn back on to the projecting piece, first the
overlapping part and then the other part is raised, upon which the lid may be
removed.

"
This invention consists of a lid which has a movable part so connected thereto.
that when the lid is pressed down a prolongation of same is brought forward and
the lid fits in two opposite grooves.
In Figure 1 this lid is shown alone, Figures 2 and 3 are plan view and vertical
sectional view which show the same in connection with the box. The lower
movable part a of the lid i is movably connected by hinges or pins x to the other
part i; and in the middle it is provided with a round upper projecting piece b
which goes through an opening in the upper part of the lid when the same is shut
down, as shown in Figures 2 and 3. A metallic plate or disc d of the same
diameter as the said projecting piece b is placed on the said projecting piece b so
that it can revolve round an eccentrically placed pin h. If the plate or disc d is
turned back in the position shown in full lines in Figure 2 it is free to fall down
into the position shown by the dotted lines in Figure 1, if on the other hand the
plate or disc d is brought forward to the position shown by the dotted lines in
Figure 2, it is clear that the movable part a is joined tightly to the upper part of
the lid i, so that a and i may be regarded as a single stiff lid.
If it is desired to lock the box A with a lid of this kind the latter is placed with
its middle part raised in the position shown by dotted lines in Figure 3 with the
end in a groove / formed in the end of the box and the movable part a being
then pressed down, enters the groove m formed in the other end of the box. If the
lid is now pressed down its ends and a will exactly fit into the grooves / and m,
and the projecting piece b with the plate or disc d protrude through the corre-
sponding opening in the upper part of the lid i as shown in full lines at Figure 3.
In order to fasten it securely, the plate or disc d is turned round its pivot h to the
position shown by the dotted lines in Figure 2, whereby the plate or disc d fits
into the slot e formed in the end of the box. Now the removal of the lid i from
the box A is impossible as long as the plate or disc d' remains in the slot in the
dotted position. In order to fasten it more securely, a string, pin, or padlock or bolt
may be put through the hole f in the projecting part of the plate or disc d.
Figure 4 is a side view, Figure a plan, Figure 0 a detail view and Figure 7 a
plan of a modification of the lock up lid. The box A is provided with the hook-
shaped pieces of hoop iron g g¹ on two opposite sides, and the lid a is movably fixed
to g at x, Figure 4. On the other end the lid a is provided with the before-
described projecting piece b and the plate or disc d movably fixed at h. Hereby it
will be seen that the part a forms the lid for shutting the whole box, the mode of
fastening same is as follows. When the lid a is put on the box (Figures 5
and 7) the piece of wood i, Figures 6 and 7, is hooked by its pins y at each end
into the hooks formed on g', and pressed down. The projecting piece b with the
eccentrically pivotted plate or disc d on the lid a, then fill up the corresponding
hole or opening in the piece i, the plate or disc d is then turned round into the
dotted position Figure 5 whereby d projects through the slot e in a projecting side
of the piece i, and the locking is effected. In reopening, it is necessary first to
turn, the plate or disc d back on to the projecting part b, and then remove the piece

page_text: of wood . In this case also the plate or disc d is made fast by a lock or pin or
string through the hole f near the edge thereof.
Figures 8 to 11 show a further modification Figure being a side view,
Figure 9 a plan, Figure 10 side view of the lid and Figure 11 vertical section
through the box and lid.
Also in this case the lid proper a is provided with a projecting piece band an
eccentrically pivotted plate or disc d. The cover a is held in its position by the
two parts i and 2 which are hinged near each end of the box by means of the
pieces of hoop iron g and g' or in any other suitable manner so that there is room
for the lid to go between them and the box The locking up is arranged in the
following manner. When the parts i and are brought into the position shown
at Figure 8, the lid a (Figure 10) is slipped underneath them on to the box A,
then is put down, and i afterwards, and the projecting piece b fits into the
corresponding opening in the middle." The part i, as shown in Figure 11,
overlaps . Then the plate or disc d is turned round to the dotted position shown
in Figure 9 and d rests in the slot e of the clamp g of the part i which overlaps
and a lock, string, or pin may be put through the hole of the plate or disc d
for holding it more securely. In order to undo the lid, the plate or disc d. is
drawn back on b, first i and then ¹ is raised, upon which the lid a may be
removed.
Having now described the nature of the said invention and in what manner
the same is to be performed I declare that I claim as the invention communicated
to me.
First The prolongation of the lid i by means of the movable part a whereby
the lid when put down is pressed into two opposite grooves k and m formed in
the box substantially as described with reference to Figures 1 to 3.
Second-The arrangement of the disc d which turns on a pin h for the uniting
of the movable part a with the fixed part i of the lid so as to effect a perfect
closure substantially.as described with reference to Figures 1 to 3.
Third The lid a which by the hoop iron pieces g is connected with the box A
so as to turn and provided with the piece b in combination with the part i which
bears against the hook parts of the pieces g¹ and which can be firmly connected
with the lid by means of the disc d turning on the pivot h substantially as
described with reference to Figures 4 to 7.
t
... Fourth-A locking lid for boxes and other vessels consisting of the part a
provided with the piece b and disc d-which can turn; on pivot h, and of the two
parts and which overlap each other and are connected to the pieces g and g¹
so as to be able to turn on the pins x and y, the disc d forming a firm connection
between the three parts a, i and i and with the box A substantially as described
with reference to Figures 8 to 11.
In witness whereof I the said Gerard Wenzeslaus von Nawrocki have hereunto
set my hand and seal this Seventeenth day of January in the year of our Lord
One thousand eight hundred and eighty four.
