COMPLETE SPECIFICATION.
An Improved Portable Box.
We CARL JOSEPH AUGUST KREIBIG of 18 Pulsnitzerstrasse, Master Potter, and
FRIEDRICH PAUL STEIN of 6" Martin-Lutherstrasse, Master Joiner, both of Dresden,
Saxony in the Empire of Germany, do hereby declare the nature of our said invention
and in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement:-
This invention has for its object the construction of boxes in an improved manner
whereby they are capable of being folded and rendered easy for transport and occupying
little space for storage.
..
In carrying out our invention we construct a box or case arranged and combined in
such a manner that, while possessed of great strength and durability, it can be easily
and rapidly folded or made up. The sides, top or lid, and bottom are all made
separate from one another, but are made to mortice one to the other, and fixed by
means of bolts or other means.
And in order that our said invention may be particularly described and ascertained
reference is hereby made to the accompanying drawings, in which similar letters of
reference indicate corresponding parts.
Fig. 1 is a plan view shewing the sides detached.
Fig. 2 is a plan view of the box or case with the lid or cover removed.
Fig. 3 is a plan view of the lid or cover.
Fig. 4 is a side elevation, and
Fig. 5 is an end elevation of the box showing more particularly the corner
fastening.
abcd are the four sides of the box or case, all of which are fitted with lugs or pro-
jections through the outer extremity of which a hole is drilled or otherwise
forined.
These lugs are so arranged that when the sides are in their proper position the lugs
are capable of receiving a screwed bolt which is passed up from the bottom of the
box, through holes formed therein, through the lugs e and then through the
holes formed in the cover or lid of the box i.
The two sides a and c have slots e made to receive the lugs e of the sides b
and d.
In order to more securely fix the lid or cover i in position we fit screw
sockets to the sides a and c as shown in Figs. 1. 2 and which receive screw
bolis m passed through the lid i and bottom respectively.
When additional strength is required we sometimes fit rails or battens 111213,
to the sides, bottom and top of the box which are kept in position by screws or
otherwise.
In order to form or set up the box or case, the four sides a b c and d are placed
on the bottom g in such a manner that the lugs e of the sides b and d enter the
slots or mortices e in the sides a and c; the four screw bolts are now passed up
through the bottom and also through the lugs e; the lid is placed on, the bolts f
entering the holes ¹, nuts 72 are screwed down and the whole is firmly
secured.
A box or case so formed and constructed is capable of enduring rough handling
without fear of the parts becoming damaged or loosened.
We do not confine ourselves to the exact arrangement of details as they may be
interchanged or equivalent devices may be used.

page_text: Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed we declare that what we
claim is
1. In folding portable boxes or cases the manufacture and use of the lugs e,
fitted to receive the bolt, substantially as and for the purposes hereinbefore
described and illustrated by the drawings.
2. The general construction, combination and arrangement of the several and
respective parts together constituting our improved folding portable box, substantially
as hereinbefore described and illustrated by the drawings.
