Improvements in Cardboard and similar Boxes.
I, JOHN EDWARD THORNTON, of Rokeby, Oldfield Road, Altrincham:
Cheshire, Manufacturer, do hereby declare the nature of this invention to be as
follows:-
The object of this invention is to produce well finished boxes in a cheaper and
more convenient manner than hitherto.
It has hitherto been usual in making well-finished boxes to use common board
(such for instance as strawboard) to form the box, which was scored, bent up to
shape, and then secured by calico or other strips, and afterwards covered with
suitable paper to give it a nice appearance. Sometimes the binding strips were
dispensed with, the covering paper serving to hold the joints of the box
together.
Sometimes boxes were made either of leather board or of common straw board)
and similar boards alone, without covering, but this method does not produce jas
nice a finished box as a covered one.
In making boxes under this invention: I proceed as follows:-
;
First a common board such as strawboard, wood pulp board, or similar material,.
is lined or covered on one or both sides with the required kind of covering paper!
or other material in the usual way.
It is then cut to the desired size and shape, and punched or perforated where.
required, and is also bent or scored. so that it will readily fold.
Instead of scoring it in the old fashioned way by partial cutting through by a
sharp scoring knife, I prefer to either take a piece out on the inside edge of the,
fold in the form of a groove by the usual methods, or to bend it as is often doue;
by means of a bending machine.
This enables the covered board to be bent up, without breaking the covering,
on the. outside of the fold, which would otherwise be the case if scored in the
ordinary way..
To further guard against the danger of breaking the covering paper and to
render the folding, easier, I pass the board through the bending machine
immediately after covering, whilst damp, before it becomes absolutely dry. The
cut edges of the board are then printed, coloured, stained, or covered with paper
or other binding, strip, so that, when made up the finished box shall not show raw..
edges of comnion board between the coverings.
This finishing of the cut,edges may be done in various ways. For instance the
boards can be placed in a pile after cutting, and their cut edges coloured by,
rollers, brushes, dipping, or in any other suitable manner. In many cases however,
Ifind, it convenient to colour them singly, which may with advantage be done by
passing them in contact with a printing roller which applies the ink or stain, where
required. It may be applied not only to the cut edge, but also to the edge of one;
or both surfaces, so as to form an edging or border when the box is made up. If
a binding strip is used instead it will form a similar border. The printing, or
colouring method, however, is preferred. on account of its cheapness and efficienoy.
The edges of the board may also be chamfered, rounded, or otherwise shaped, by,
a revolving cutter or shaping tool or other means.
The box.may be fastened together in various ways, for instance, by gluing or
pasting the parts and compressing them together; by "bitting up" the corners

top edges to secure the inturned and upturned parts that may be used to form

Improvements in Cardboard and similar Boxes.
I, JOHN EDWARD THORNTON, of Rokeby, Oldfield Road, Altrincham, in the
County of Chester, Manufacturer, 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 :-
The object of this invention is to produce boxes of cardboard and similar
material of superior finish in a cheaper and more convenient manner than
hitherto.
Hitherto it bas been usual in making well finished boxes to use common board
(such for instance as straw board) to form the box, which was scored, bent up to
shape and the joints secured by strips of calico or other material and afterwards
covered with coloured or ornamented paper to give it a nice appearance. In some
cases the binding strips were dispensed with, the covering paper serving to hold the
joints of the box together.
In other cases boxes have been made of leather board, straw board or other
descriptions of board without covering but these on account of the raw edges do
not present as good a finish as those in which the joints are covered by paper.
My invention consists essentially in constructing the boxes of any of the well
known materials and finishing the raw edges by colouring dyeing or staining them
or by chamfering rounding or otherwise shaping such edges to give a neat or
ornamental appearanco.
It will be fully described with reference to the accompanying drawings in which
as an example I have shown one form of box finished in accordance with the
invention.
I take a common board such as straw-board' wood-pulp-board or the like covered
on one or both sides with paper or other suitable or usual covering material. This
I cut or score to the desired shape by any of the ordinary methods but instead of
scoring by partially cutting through with a sharp scoring knife I prefer to either
take a piece out on the inside edge of the fold in the form of a groove or to bend
it in a beuding machine so as to produce externally as few raw or cut edges as
practicable and prevent the breaking of the covering on the outside of the folds
when bent up.
The cut edges a of the board I then colour dye or stain with any desired colour
or shade of colour so that when the box is made up no raw edges of common board
will show upon the box.
**
Instead of or in addition to the colouring of the edges I chamfer round or
otherwise shape them by means of a revolving cutter or other shaping tool.

page_text: In addition also to colouring or shaping the cut or raw edges I sometimes print
or apply a line or stripe 6 of colour along one or both surfaces of the board
adjacent to the out edges to form an ornamental edging or border when the box
is made.up.
The colouring or finishing of the cut edges a of the board may be effected in
various ways. For instance the boards may be placed in a pile after being cut
and the cut or raw edges a be coloured by means of rollers or brushes or by
dipping them in the colouring or dyeing material or in other convenient manner.
In many cases however I find it convenient to colour the boards singly, which
may with advantage be done by passing them in contact with a printing_roller
which supplies the ink or stain where required. In this way the surfaces adjacent
to the edges may also be coloured to form a border.
"
The boxes may be made of any ordinary construction and fastened together in
any desired way such as by glueing or pasting the parts and compressing them
together; by "bitting up the corners with binding strips as usual; or by a
binding strip or flap which folds over the top edges to secure the inturned and
upturned parts that may be used to form the ends or sides of the box; or by metal
fasteners, buttons, or other suitable means..
The main point of the invention is the production of a well finished box by
means of covered board so that it shall not show the raw cut edges of the board
between the coverings, shall have rounded chamferred, or other shaped edges, if
required and shall be fastened together in such a manner that the covering the
edging and the fastening will combine to produce a well finished box in a cheaper
and more convenient manner than heretofore.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is.-
1. The method of finishing cardboard or other boxes by colouring staining or
dyeing the raw or cut edges of the board substantially as described.
2. The method of finishing cardboard and other similar boxes by colouring
staining or dyeing the raw or cut edges of the board and by printing a line or
stripe of colour on one or both surfaces adjacent thereto substantially as
described.
3. The method of giving a finish to cardboard or other similar boxes by
chamfering rounding or shaping the cut edges of the board with or without the
addition of colouring material thereto or the surfaces adjacent thereto substantially
as described.
4. A cardboard or other similar box finished or ornamented substantially as.
described.
