I NATHANIEL BOTT CHADWICK of 3 St. Anns Place St. Anns Road Stamford Hill
in the County of Middlesex Engineer, do hereby declare the nature of this invention
to be as follows:-
This Invention relates to a plan to make a Box of Paper Cardboard or other thin
material which can be opened out flat for shipping or storage purposes and which can
also be folded up so as to form without the use of Glue or other adhesive substance or
stitching a perfect box which can be used for every purpose.
These Boxes can be made out of paper Cardboard thick Millboard, or thin Match
Wood. The difference between this box and any other box now in use consists in two
sides or ends of the box being double as shewn in figure 1 and so folding over the
sides running at right angles with them that the tongues d. d. d. d. enter the
holes c. c. c. c. as shewn in Fig. 2.
The advantage of the Box is that the corner pieces c. c. c. c in Fig. 1 being folded
under the sides b. b. and the tongues d. d. d. d. being pushed into the holes c. c. c. c
leaves the outsides of the box perfectly plain and also has no projection on the inside
to prevent the lid which is a fac simile of the box itself (only shallower if necessary)
from closing down or taking off without any difficulty.
The mode of making these boxes would be to indent the material used along the
dotted lines in Fig. 1 in such a manner that they would always bend along the
indentation then cut the holes c. c. c. c. and a notch f.f.f.f.f.f. f. f. on each side to
form a tongue d. d. d. d. then having cut along the marks e. e. e. e. as far as the
intercepting marks g. 9. g. g the box will be ready to be folded or can be packed flat.
until wanted for use.
When thick material is used it will be necessary to remove a portion of the material
so as to allow it to bend freely and without breaking and this I purpose doing in a
half circular form as in figure 3 so that the bend would always come in the middle of
the part removed thus assuring accuracy in bending. In some material, it may be
requisite to glue or otherwise fasten linen or other tough material on the outside of
the box to strengthen the bending parts.

page_text: 1, NATHANIEL BOTT CHADWICK late of St. Anns Place St. Anns Road Stamford
Hill in the County of Middlesex but now of 29 Lealand Road Stamford Hill aforesaid
Engineer, do hereby declare the nature of the said invention and in what manner the
same is to be performed, to be particularly described and ascertained in and by the
following statement :-
The object of my Invention is to make boxes of paper, cardboard, millboard, match-
wood, or other thin material, which can be opened out flat for shipping or storage
purposes, and which can also be folded in such a manner as to form (without the use
of glue or other adhesive substance, or stitching, with wire, string, thread or equivalent
means) a complete and perfect box, suitable for all ordinary purposes.
And in order that my 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.
Figure 1 is a plan view, shewing the form of a piece of suitable material, cut,
marked, grooved, and slotted, ready for making a box; Figure 2 is a perspective view
of the same, folded and formed into a box, and Figure 3 is an enlarged section,
shewing one method of forming the grooves g g, for convenience in folding.
The material is cut to the form shewn in Figure 1, with slots c. c and f. f,
tongues d d, and grooves or indentations for folding the same at g g.
When so cut and prepared, the two sides 6' 6', together with the ends b² 62 62 62,
are first raised; the ends are then turned towards each other, across the ends of
the box; the sides b are then raised, and the portions 63 are turned down over 2, the
tongues being inserted into and passed through the slots c, thus doubling the
material at the two ends, and forming the complete box, as shewn in Figure 2.
The lid of the box is formed in a similar manner, the depth being arranged as
required.
The advantage of forming boxes in the manner described, is that the end pieces b²
being folded under the sides b and the tongues & being pushed into the holes the
outsides of the boxes are left perfectly plain, and no projection is formed on the
inside.
When thick material is used in the formation of the boxes, it is necessary to remove
a portion of the material, so as to allow it to bend freely, and without breaking the
material. In order to effect this, I preferably groove the material in a V or a semi-
circular form, as shewn in Figure 3, the grooves being made so that the material may
always bend in the middle of the groove, and thereby ensure accuracy.
In square boxes where the ends bi overlap each. other sufficiently, one tongue only

page_text: is formed and pushed through the coincident holes c c in the flaps 62 instead of the
arrangement shown in Figure 1.
When the ends of the flaps 6 are so long as to overlap the slots c, a suitable portion
is cut off the same; but this applies only to boxes, more especially deep ones, and not
to lids of boxes.
In using somo materials it becomes necessary to glue or otherwise fasten linen or
other suitable material or fabric on the outside of the box to strengthen the bending
parts.
Having now particularly described and ascertained the nature of the said Invention
and in what manner the same is to be performed I declare that what I claim is :-
The manufacture and use of boxes, and the preparation of materials for making
boxes, and lids for the same, having sides 6 and with ends 62, slots c and,
tongues d, and folding grooves or indentations g substantially as herein before described
and shewn on the drawings.
