We, LUDWIG FINK and LEOPOLD CASPER, both of 12 Trift Str. Berlin, in the
Kingdom of Prussia, German Empire, manufacturers, do hereby declare the nature
of this invention to be as follows:-
--
Our improved boxes are made for the purpose of being transported from the place
where they are manufactured to the place where they are used, in a flat state, that
is each of them consists of a single sheet of paste-board, so as to be piled one above
the other for saving room.
The boxes are made of a sheet of paste-board which has at each side of the part
representing the bottom, a projecting part of right-angular shape, which serve as
the side-walls of the box when bent up to a right angle with regard to the bottom.
For joining these side walls we provide the rims of the same which constitute the
corners, with holes or cuttings at regular distances. Through these holes or cuttings
we pass, when the box has to be used, a hinge-like wire of which the one end enters
the holes of the one side wall and the other one the adjacent holes of the adjacent
side wall. For stiffening and making the boxes more durable we apply also edge-
joints of sheet metal of right angular shape in section, which are provided with
corresponding holes as those in the side-walls and we then pass the hinge like wire
through both, the holes of the paste-board as well as through those of the sheet metal
joints.
We further strenghten the box by providing its side walls near their ends with
scores by running them through suitable rollers, we also give the box a coating
consisting of demara resin, or mastic, or gum-arabic, mixed with lye of borax in a
concentrated state.

page_text: We, LUDWIG FINK and LEOPOLD CASPER, both of 12, Trift Strasse Berlin, in the
Kingdom of Prussia, German Empire, Manufacturers, 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 :-
--
Our invention relates to boxes, and has for its object to facilitate the transport of
such boxes, by packing or piling them one above the other in a flat state, and by
joining the sides of the boxes when arrived at their place of destination, by means of
hinge-like wires, and our invention has further for its object to strenghten these boxes
by grooves and caps of sheet.metal and by a durable coating.
The manner in which we carry out our invention is shown in the accompanying
drawings, in which:
Figure 1 is a plan of a box being in a flat state.
Figure 2 shows the same in a side view.
Figure 3 represents part of the box when fitted together.
Figure 4 shows the hinge like wire used for joining the sides of the box.
Figure 5 shows a section of a box.
Figure 6 is a plan of a box when finished.
Figure 7 illustrates the form of the sheet metal corner binding pieces.
Figure 8 is a perspective view of one corner of the box, the wire being not yet
inserted.
Figure 9 shows a rolling apparatus for producing, longitudinal grooves in the side
walls of the boxes, and
Figure 10 is a sectional view of a side-wall being provided with a stiffening cap.
The boxes consist of a single sheet of paste board having the shape of a cross fig. 1.
The centre part of this cross constitutes the bottom o, the extending sides form the
walls bbbb of the boxes. The rims of the walls which make the vertical corners of
the box, when put together, are provided with slits a, and the parts between these
slits a are bent or pressed alternately to the outside and inside of the box, as can be
best seen in figures 3, 5, 7 & 8. Through the loops or hinges thus formed we pass
wires d or d¹ at each corner; the wires are used when the corners of the boxes are
kept together by edge-joints c of sheet metal, while we may use the hinge-like wire d
also in those cases where we do not strenghten the boxes by said edge-joints, which
are made and cut according to the cuttings in the side-walls of the boxes and the
parts between these cuttings are bent or pressed in the manner as those of the paste
board.
To give these boxes a still greater durability we provide them with horizontal or
vertical corrugations or channels by running them through the rolls h and g, figure 9,
the one having a groove k, the other a bead or tongue 7 which produce said
corrugations e in the boxes, as shown in figure 10. We further provide the upper

page_text: edge of the boxes with caps f, figure 10, which may be applied before passing the
paste-board between the rollers, whereby these caps are also corrugated.
In order to make the boxes impervious to water and dampness we coat them with
Demara resin, or mastic, or gum arabic mixed with lye of borax, the latter being in
a concentrated state. Thus we are able to manufacture boxes which may well be
transported great distances without being injured either by loads or weights resting
on them, or by water or dampness, and the cost of transporting being much smaller
than other boxes.
Having now particularly described and ascertained the
invention and in what manner the same is to be performed we
claim is:
nature of our said
declare that what we
1) Boxes consisting of one piece of paste board, of cross like shape the sides of
which being provided with slits, a through which a hinge like wire is passed.
2) Boxes consisting of one piece of paste board of cross like shape, the sides of
which being provided with slits a and edge-joints c provided with like cuttings,
through which a wire is passed, for the purpose as described.
3) Boxes being made of one piece and having their corners joined by wires and
being provided with sheet metal caps f.
4) The coating of boxes with Demara resin, or mastic, or gum-arabic mixed with
lye of borax in a concentrated state for the purpose as described.
Darted this 11th day of June 188d.
