PROVISIONAL SPECIFICATION.
Improvements in the Manufacture of Boxes of Cardboard and the like
Material.
I, RIDLEY JAMES URQUHART, of 12, Gardner Road, Tue Brook, Liverpool, in
the County of Lancaster, Consulting Engineer, do hereby declare the nature of this
invention to be as follows:-
This invention relates to boxes made from cardboard, strawboard, leatherboard
and material of a like nature, -the chief object of this invention being the econo-
mical manufacture of such boxes.
The improvements hereinafter set forth have reference to the method of secur-
ing together the edges of the sides of the box where they meet at the corners.
The invention is characterised by the use for each fastening of two vertically.
disposed slots, formed near to the ends of the sides of the box and opposite to
one another, and in conjunction with each pair of slots of a long tongue formed
in some cases from the material of the box, the root of which tongue is opposite
to and approximately parallel with one of the slots and when in use is turned
back upon itself at the root and passed into the slot or slots opposite to it.
In other cases the tongue may be formed from thin metal and have at its root
a smaller tongue or preferably several smaller tongues, which pass each through
a slot pierced through the material of the box and after being bent and pressed
down or clamped are firmly secured to the box.
When these tongues are made of thin metal, a series of them may be formed
in one piece.
1
When the tongues are formed in one piece with the bottom and sides of the
blank to form the box, I prefer to form two of the sides with ears thereto, and
bend these ears over at right angles so as to overlap the contiguous
side for a short distance. Each ear has a further projection in the
form of a tongue. This tongue at its root is bent inwards at right
angles and opposite to its tip the contiguous side
is pierced
with
a suitably sized slot through which the tongue is passed and it is
then bent back upon itself in order to lie flat with the inside surface of the
pierced side. In order to keep the tongue in this position and to prevent its
coming out of the slot, it is left long enough to pass through another slot pierced
in the side from which the tongue and ear are formed.
I may, however, in a modification, form the tongue with an oblong slot therein
which is vertically disposed and when the tongue is passed through the slot in
the contiguous side, the slot in the tongue lies clear upon the inside surface of
this side. Through this second slot I pass the tip of a tongue formed at the end
of the overlapped side and turned back upon itself at the root thereof.
In another modification, the end having the overlapping ear is formed with
two slots in the ear, one near to the corner and the other near to the edge of
the ear, but both vertically disposed and parallel to one another. The tongue

page_text: at the end of the contiguous side passes through the first named slot from the
outside and then into the second named slot from the inside.
In a further modification, the ear lies upon the inside of the contiguous side
and the latter is formed with a slotted tongue bent at right angles at its end.
This passes through a slot in the ear, and the first tongue passes through the
slotted tongue and may pass into a slot formed opposite to it in the side which
is formed with the ear.

Improvements in the Manufacture of Boxes of Cardboard and the like
Material.
I, RIDLEY JAMES URQUHART, of 1, Woburn Hill, Stoneycroft, late of 12, Gardner
Road, Tue Brook, Liverpool, in the County of Lancaster, Consulting Engineer, 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 follow-
ing statement:-
This invention relates to boxes made from cardboard, strawboard, leatherboard
and material of a like nature, the chief object of this invention being the econo-
mical manufacture of such boxes.
The improvements hereinafter set forth have reference to the method of secur-
ing together the edges of the sides of the box where they meet at the corners.
The invention is characterised by the use for each fastening of two vertically
disposed slots, formed near to the ends of the sides of the box and opposite to
one another, when the box is set up, and in conjunction with each pair of slots
of a long tongue formed preferably from the material of the box, the root of
which tongue is opposite to and approximately parallel with one of the slots and
when in use is turned back upon itself at the root and passed into the slot or
slots opposite to it.
j
In other cases the tongue may be formed from thin metal and have at its root
a smaller tongue or preferably several smaller tongues, which passes or pass each
through a slot or slots pierced through the material of the box by which the
large tongue is clamped to the material of the box.
When these tongues are made of thin metal, a series of them may be formed
in one piece.
When the tongues are formed in one piece with the bottom and sides of the
blank to form the box, I prefer to form two of the sides with ears thereto, and
bend these ear's over at right angles so as to overlap the contiguous
side for a short distance. Each ear has a further projection in the
form of a tongue. This tongue at its root is bent inwards at right
angles and opposite to its tip the contiguous side is pierced with
a suitably sized slot through which the tongue is passed and it is
then bent back upon itself in order to lie flat with the inside surface of the
pierced side. In order to keep the tongue in this position and to prevent its
coming out of the slot, it is left long enough to pass through another slot pierced
in the side from which the tongue and ear are formed. The ear and tongue will
hereinafter be referred to as the tongue.
In order that my invention may be well understood I have attached hereunto a
sheet of drawings to which I will now refer.

page_text: In the said drawings Figure 1 shows the bottom part of a box made according
to my invention in perspective view:
Figure 2 the blank out of which it is formed;
Figure 3 a horizontal section through one of the corners;
Figure 4 a blank for forming a box and lid in one piece.
The blank for producing the box is shaped out of a rectangular piece of
material the length of which is equal to the length 7 of the box with the addition
of double the depth d, while the width equal to the width w of the box with
the addition of double the depth d, there being no projections and consequently
no cutting to waste. At each corner one of the sides s is formed with a tongue,
which in forming the box is bent over at a right angle so as to lie flat upon
the adjacent side when the sides have been bent up at a right angle to the
bottom. Each tongue has preferably a broad flaplike root f and a narrowed end t.
The side overlapped by the flap is pierced by a vertical oblong slot a at the part
opposite to the commencement of the narrow part t and of the same length as
the width of the tongue, which latter is first bent at a right angle and passed
through the slot a, and then folded flat upon the inside surface of the pierced
side. In order to keep the tongue in this position and to prevent its coming out
of the slot a, it is made long enough to pass through another slot a pierced in
the side of the box on which the tongue is formed and opposite to the folded back
end of the tongue.
By thus folding back the tongue and securing its end in a slot in the same side
of which it forms part a much firmer and stronger connection of the two sides is
obtained than if the tongue were only passed through the slot a.
Figure shows the blank out of which the box is formed, consisting of the
bottom part 6 and the sides s, s1,2, and 3, two of which s¹ and s3 are cut with
two tongues ft and have the slots a' for the ends of the tongues pierced in them,
while the other sides s and shave the slots a for the roots of the tongues
pierced in them. It is of course immaterial whether two of the sides are formed
with a tongue at each end, or whether each side has a tongue at one end and a
slot a at the other, but the former arrangement is more readily cut. Preferably
the tongues are nearer to the top edges than the bottom, as shewn.
Loose lids are formed in the same way as the boxes, while if the lid is to be
connected to the box a blank as shewn by Figure 4 is used, the parts b, s, s¹, s², sil
forming after folding the bottom part, and the parts 1, 11, 12, 13 the lid.
Preferably the blanks are scored or grooved along the lines where they are to
be bent, as shewn on Figures 2 and 4.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is:
-
1. The improvements in the manufacture of boxes of cardboard, leatherboard and
material of a like nature which consist in shaping suitable blanks of the material
to form the bottoms and the covers, the sides and a tongued flap at each corner,
piercing a slot at the root of each tongued flap and at or near to the end of the
other side, and scoring, grooving or making the blanks to indicate the sections
to be set up and bent in order to form the box and secure the corners together
by passing the tongue through the slot in the adjacent side, doubling it back and
passing its tip into the slot at its root substantially as herein before described
and illustrated with reference to the several views of the drawing.
2. The improvement in the construction of folding boxes of cardboard, leather-
board and material of a like nature which consists in the manner of securing the
sides together at the corners by means of tongued flaps each tongue overlapping
the adjacent side, passing through a slot therein, doubling back upon the side
and entering a slot in the side from which the tongued flap springs substantially
as herein before described and illustrated in the drawings.
3. In the manufacture of boxes of cardboard, leatherboard and material of a

page_text: like nature the use of a fastening for the corners comprising a tongued flap and
two slots formed, arranged and employed in the manner substantially as herein-
before described and illustrated in the accompanying drawings.
4. The improvements in boxes made of cardboard, leatherboard and material
of a like nature substantially as hereinbefore described and illustrated.
