Sections 18 to 21 of the Patents, Designs, and Trade Marks Act, 1882
and of Dies therefor.
I HENRY HARRIS LAKE, of the firm of Haseltine, Lake, and Co., Patent Agents,
Southampton Buildings, in the County of Middlesex, do hereby declare the nature of
my invention and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :-
My invention relates first; to an improvement in paper and other boxes.
Secondly, to an improvement in dies for stamping out the boxes, and
Thirdly, to an improved method of forming the dies.
The chief object of my improvements is to so construct paper or other boxes that
they may be easily and readily folded, and that when in their closed adjustment
they will be so folded as to effectually prevent the escape or sifting out of their
contents.
The object of my improvement in dies is to provide a device of this character
which will at one operation cut the material, half cut the same on certain lines, and
score it on others, on which it is to be folded in forming the box.
A further object of this improvement is to construct a die of practically one
piece, and obviate the necessity for forming separate blocks wherewith to hold the
several sections of the cutting and scoring wires together.
A further object of this improvement is to construct a die which shall be simple
and economical in construction, capable of being readily and easily formed and
which shall be durable and efficient in use.
The object of the third portion of my improvement, namely, the method of
forming dies, is to form a die in practically one piece, and in such manner as to
effect a great saving in the cost thereof and in the time required in making the
several parts and arranging them in their proper positions.
In the accompanying drawings,

Figure 10 9 is a sectional view thereof taken on the line x, x of Figure 8.
Figure 110 is a top plan view of the templet.
Referring to Figures 1, 2, 3, 4 and 5, A represents the body of the box constructed
of any suitable material and dimensions, the opposite sides B, B, of which are
somewhat lengthened, as shown in Figures 1 and 3 of the drawings forming the
flaps D, E. The sides C of the box are constructed with the curbs F scored to fold
on the lines a, b, a, c, b, c, d, c, and e, b, thereby forming the three small sides G, H, I.
The sides G, I, extend upwardly for about half the length of the flaps D, E, the
sides I having straight top edges which impart thereto a triangular shape, while the
sides G are extended above the top edges of the sides I and have their apices in a
straight line with the apices a, of the sides H. By pressing inwardly the sides H,
which fold on the lines b, c, the sides C, J, GI are drawn downwardly. The upper
end of the flap E is then passed in between the sides G and flap D and the latter then
bent downwardly, the upper portions or extensions of the latches G, passing in
between the sides I and flaps E the said sides G, H, I, foldings on the lines a, b, a, c,
b, c, e, b, and d, e, until the under side of the flap D rests squarely on the upper side
of the flap E and the sides G, I, rest on the sides H. Before folding the box, a
suitable adhesive substance is applied to the parts that come in contact, and the
several sides or folds are thereby held tightly in position.
It will be noticed that the adhesive material applied to the outer side of the
latch G and the inner side of the flap E, is, when the box is in the act of folding
carried or pushed forward on the latch G by the edge of the side I, and on the
inner side of the flap E by the edge of the latch G, thereby entirely causing an
exudation of the adhesive material on a, d, but in the greatest quantity at d, the
point which operates to entirely and effectually seal the opening between the latch G
and side I.
It will be readily understood that the box as shown in Figure 4 of the drawing
is capable of being folded in a manner similar to the box above described, but
I would recommend the use of the former, as in the latter it will be noticed that
an opening will be left between the upper edges of the top e and g, affording an
escape for the contents of the box, and which necessitates a reinforcing piece
therein; but by virtue of the construction as herein before described, the upper end
of the side G, when the box is folded, passes in between the flap E and sides I, and
completely shuts the opening and forms a tight and closed box, thus doing away
with the extra piece of material.
Similar extensions may be formed on the sides I, as shown in Figure 5, which
when the box is folded fit in between the sides G and H, but as this form of box is
somewhat more difficult to fold, I would recommend the use of the box constructed
as first described.
Referring to Figures 6, and 7 and 2, A represents the base plate of the die, ton
which rest are indirectly attached the cutting wires B arranged to impart to the
material being cut, the proper outline. On To the plate A, are also rest indirectly
attached the cutting wires C, the edges of which are located in a plane somewhat
below that of the edge B, the purpose of the cutting wires C being to partially cut
through the material of which the blank is formed, on certain lines on which the box
is to be folded. These cutting wires B, C, are made of hardened steel, in order to
prevent losing their sharpened edges when they come in contact with the metallic
plate on which the material being cut rests.
D represents brass wires arranged to score the blank on the lines on which it is

page_text: to be folded, the upper edges of these wires being located in the same plane as that
of the wires C.
Upon the surface of the plate A is a coating of metal A¹, celluloid, or other
material, serving to hold the cutting and scoring wires in position on the plate, the
said metal or celluloid serving as an anchorage for the wires, and also practically
forming the die of one piece. This arrangement 1 have found far superior to
the ordinary cutting dies which have generally been constructed of metal blades
arranged in accordance with the outline to be given to the blank and the brass.
scoring rod all held in their proper relative positions by blocks, the whole being set
up similar to a form of type, and then bound or locked together. It is very evident
that the construction of this form of die involves a great expenditure of time and
labour, as for instance in constructing a die of the form shown in the drawings, it
was first necessary to arrange the metal blades similar to the wires B and C, then
the scoring pieces D, and then to form blocks to fit in between the blades and
scoring pieces. It will be readily seen that to form blocks similar in contour to the
polygon a, the triangle b, the triangle c, the quadrilateral d, etc., in order to hold
the blade in position, added materially to the cost and time of producing the die,
and that by my improved device these objections are entirely overcome.
Several of these dies may be formed on the same plate and a corresponding
number of blanks cut from a sheet of material at one operation, the edges of the
cutting wire being preferably provided with two or more notches to prevent said
blanks from being entirely severed from the sheet of material.
I do not wish to have it understood that I in anywise limit myself to any
particular metal or substance for forming the anchorage of the wires, as I might
use any of the metals, celluloid, or other substance.
And further I would have it understood that I do not limit myself to the exact
construction and arrangement of parts as shown and described, as changes might
be made therein in accordance with circumstances, as for instance some metals or
substances might be used wherewith to hold the wires with which it would be
unnecessary to use the backing plate A.
In constructing my improved die 1 first form the templet A, referring to
Figures 8, 109, and 14 10, for the purpose of temporarily holding the wires in their
proper relative positions and which consists of a plate made of metal or other material,
and formed with the outer groove a, preferably by a ruling machine and adapted to
receive the inverted wires a¹ for cutting the outer edge of the blank.
This groove is
of such depth as will contain a wire of slightly greater thickness than the material
of which the blank is composed in order to ensure such wire when in the die cutting
entirely through the material. The templet is also formed with grooves b, d, c, some-
what more shallow than the grooves a, for respectively containing the cutting wires b¹
and scoring wires c'. By thus placing the wires b', they will serve to cut only
partially through the material on lines on which the blank is to be folded. After
the wires have been properly placed within the grooves, a coating or layer of
metal B, celluloid or other substance is applied to the surface of the templet A, such
surface if necessary being covered with varnish or other material for preventing the
coating substance from adhering thereto. The upper edges of the groove formed
in the templet are slightly bevelled or recessed as at e¹ in order that the coating
substance B may partially enter the grooves and grasp the wires, and securely hold
the same.
After the material B has been applied a base plate C is placed thereon,
and the whole then subjected to heat and pressure, either or both in accordance
with the material employed which serves to securely unite the wire anchorage and
plate C and form a die of practically one piece. The die having the wires securely
anchored therein is then separated from the templet. It may be preferable, however, to
dispense with the base plate, the material used in grasping and holding the wires
sufficing, as before stated.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed as communicated to

page_text: me by my Foreign Correspondent, I declare that what I claim is the following claim
for the box is to be read as being confined to a box made with the side G, and in some
cases the sides G and I extending upward as shown in figures 3 and 5 so as to enable the
box to be closed tightly and prevent the escape of any powdered or like contents; and I
claim :-
First. The box A formed with the flaps D, D and the sides G, H, I, constructed
as described and of the form shown, the flap E, (when the box is folded) fitting in
between the flap D, and sides G, and the sides G, partially fitting in between the
flap E, and sides I, substantially as set forth.
Second. A die for cutting paper or other material, constructed of cutting wires
arranged in proper relative positions, and having their base edges embedded in a
plastic substance hardened to form a solid anchorage for the wires, substantially as
set forth.
Third. A die for cutting paper and other material, constructed of a base plate,
scoring and cutting wires arranged in suitable relative positions, and a coating or
anchorage attaching itself to the base-plate and embedding the base edges of the
wires and securing them in position; substantially as set forth.
Fourth. The method hereinbefore described of forming dies for cutting blanks
for paper boxes, which consists essentially in forming a templet with suitable
grooves, placing the cutting and scoring wires therein, and applying a coating or
layer of suitable substance over the templet for holding the wires in position sub-
stantially as set forth.
Fifth. The method hereinbefore described of forming dies for cutting blanks for
paper boxes, which consists, essentially in forming a templet with suitably arranged
grooves, arranging the cutting and scoring wires therein, applying a coating or
layer of suitable material to said templet for grasping and retaining said wires,
placing on said coating a plate, and finally subjecting the whole to heat and
pressure substantially as set forth.
