Method of and Apparatus for Securing Together the Sides of
Cardboard Boxes, and like articles.
I, JOSEF WEIL of 2 Johannesgasse, Weinhaus, near Vienna, Austria, Manu-
facturer of Cardboard Goods, do hereby declare the nature of this invention to be
as follows:
This invention relates to a method of, and machine for, securing together the
sides of light boxes and like articles, whose edges may be pasted or folded
together, or merely placed in juxtaposition, by means of sheet metal angle pieces
or edge fastenings, whereby the strength and durability of such articles are
considerably increased.
The machine comprises a plunger which is vertically guided in the front part
of the framing of the machine, and which is furnished with a removable block or
presser (hereinafter called a presser) recessed at its underside, which can, by means
of a foot lever, be pressed upon a horizontally adjustable block or anvil let into
the framing of the machine. The anvil is formed on its upper side to correspond
with the recess in the presser.
A grooved and bent sheet metal angle piece having been loosely fitted upon the
corner of the box to be fastened and the box placed with this corner upon the anvil,
the lever, which is normally maintained in the raised position by a spring, is
depressed by the pressure of the foot so that the presser is forced against the anvil,
pressing the angle piece close up against the box, and causing bosses or projections
on the anvil.to force the sheet metal and the intermediate substance of the box
into corresponding recesses in the presser in such a manner that the angle piece is
securely fixed, and cannot be readily taken off the box.
The recesses instead of being in the presser may be arranged in the anvil, and
the corresponding projections be formed in the recess of the presser.
Two angle pieces may be connected together or be made in one piece, or a metal
frame corresponding to the size of the box may be used, the boxes in such cases
being bordered with sheet metal on two edges or on all of them.
A machine
according to this invention is represented in Figs. 1 and 2 of the accompanying
drawings:-
Fig. 1 being a side elevation partly in section, and
Fig. 2 a front elevation partly in section.

Figs. 3 and 4 illustrate a box fastened with the sheet metal angle pieces and
Figs. 5 and 6, illustrate two forms of angle pieces.
a is the framing of the machine the front part a' constituting a guide for the
vertically movable plunger 6 which is provided at its lower end with a removable
presser c.
This presser is formed at its lower part with an angular recess c¹ which corresponds
in cross section to the corner of the box, and is provided on both sides with
recesses c², as shown in Fig. 2. The upper end 6' of the plunger is thickened
to hold in place the spiral spring d for raising the plunger.
The depression of the plunger is effected by means of a leverf which is pivoted
on a pin, passes through the forked upper end of the plunger and is connected
by the rod g with the foot lever or treadle h.
When the latter is moved downwards by the foot, the presser c is pressed against
an anvil k which is let into the front portion of the framing a, and is capable of
being pushed out to a greater or less extent according to requirement, and is fixed

page_text: by means of a set screw . This anvil is bevelled at its upper portion ¹ to conform
to the shape of the corner of the box, and is provided with projections or bosses k²
that correspond with the recesses c² of the presser.
As already mentioned there being loosely fitted upon a corner of the box A to
be treated, a groove-shaped angle piece m (Fig. 5) of sheet metal, that corner of
the box is laid upon the anvil kas indicated in dotted lines in Fig. 2. The presser
is then, by means of the treadle h pressed against the anvil, whereby the angle
piece is pressed close up against the substance of the box, and the bosses are
pressed into the angle piece and into the intermediate substance.
In order to raise the treadle and the lever after cach pressing operation,
there is provided in the framing a a spring o whose lower end is connected to the
rod g at o', and whose upper end is connected to the framing a, so that the said
spring is put in tension when the treadle is pressed down, and has a tendency
to raise the treadle h. On the lever is a sliding weight 2, by moving which
the power exerted on the treadle may be supported to a greater or less
extent, according as this sliding weight is moved away from or near to the
fulcrum f.
Fig. 3 illustrates in vertical section a box A provided with an angle piece m, and
Fig. 4 is a perspective view of a part of the said box. Instead of two angle pieces m,
one angle piece M which is twice bent, as shown in Fig. 6 may be employed.
As will be readily understood, in this case, the box is covered by this angle
piece at two corners and at the edge connecting these two corners.
Metal frames bent to correspond with the shape of the box which cover all the
upper edges may also be employed.
As a result of the impression m² (Figs. 3 and 4) which is effected by the machine
and acts as a rivet, the sheet metal angle pieces adhere strongly to the box and the
durability of the box is thus considerably increased.

Method of and Apparatus for Securing Together the Sides of
Cardboard Boxes and like articles.
I, JOSEF WEIL, of 2 Johannesgasse, Weinhaus near Vienna, Manufacturer of
Cardboard Goods, 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 :-
This invention relates to a method of and machine for securing together the sides
of light boxes and like articles, whose edges may be pasted or folded together, or
merely placed in juxtaposition, by means of sheet metal angle pieces or edge
fastenings, whereby the strength and durability of such articles are considerably

The recesses instead of being in the presser may be arranged in the anvil, and
the corresponding projections be formed in the recess of the presser.
Two angle pieces may be connected together or be made in. one piece, or a metal
frame corresponding to the size of the box may be used, the boxes in such cases
being bordered with sheet metal on two edges or on all of them.
A machine according to this invention is represented in Figs. 1 and 2 of the
drawings left with my Provisional Specification,
Fig. 1 being a side elevation partly in section, and
Fig. 2 a front elevation partly in section.
Figs. 3 and 4 illustrate a box fastened with the sheet metal angle pieces; and
Figs. 5 and 6 illustrate two forms of angle pieces.
a is the framing of the machine the front part a constituting a guide for the
vertically movable plunger 6 which is provided at its lower end with a removable
presser c. This presser is formed at its lower part with an angular recess c¹ which
corresponds in cross section to the corner of the box, and is provided on both sides
with recesses as shewn in Fig. 2. The upper end of the plunger 6 is provided
with a head that forms a support for the upper end of a spiral spring d for
raising the plunger.
The depression of the plunger is effected by means of a lever which is pivoted
on a pin f, passes through the forked head of the plunger, and is connected by
the rod g with the foot lever or treadle h.
When the latter is moved downwards by the foot, the presser c is pressed against
an anvil which is let into the front portion of the framing a, and is capable of
being pushed out to a greater or less extent according to requirement, and is fixed
by means of a set screw . This anvil is bevelled at its upper portion k¹ to conform
to the shape of the corner of the box, and is provided with projections or bosses **
that correspond with the recesses of the presser.
As already mentioned there being loosely fitted upon a corner of the box A to
be treated, a groove-shaped angle piece m (Fig. 5) of sheet metal, that corner of
the box A is laid upon the anvil k as indicated in dotted lines in Fig. 2. The
presser c is then, by means of the treadle pressed against the anvil, whereby the
angle piece is pressed close up against the substance of the box, and the bosses k
are pressed into the angle piece so that the angle piece and intermediate substance
of the box are securely fixed together.
In order to raise the treadle h and the lever fafter each pressing operation, there
is provided in the framing a a spring o whose lower end-is connected to the rod
at o', and whose upper end is connected to the framing a, so that the said spring is
put in tension when the treadle h is pressed down, and has a tendency to raise the
treadle h. On the lever is a sliding weight, by moving which the power
exerted on the treadle h may be assisted to a greater or less extent, according as
this sliding weight is moved away from or near to the fulcrum.fl.

pieces m, one angle piece M which is twice bent, as shewn in Fig. 6 may be
employed.
As will be readily understood, in this case, the box is covered by this angle piece
at two corners and at the edge connecting these two corners.
Metal frames bent to correspond with the shape of the box which cover all the
upper edges may also be employed.
As a result of the impression m' (Figs. 3 and 4) which is effected by the machine
and acts as a rivet, the sheet metal angle pieces adhere strongly to the box and the
durability of the box is thus considerably increased.

page_text: Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed. I declare that what. I
claim is
1. The hereinbefore described method of securing together the sides of cardboard
boxes and like articles, said 'method consisting in loosely fitting upon the corner of
the box a grooved and suitably bent sheet metal angle piece, in pressing this angle
piece against the material' of the box both from the inside and from the outside,
and in forming recesses, in the said inetallic angles and in the material of the box,
substantially as and for the purpose specified.
b
+
2. For carrying out the method specified in the preceding claim, a machine
comprising a suitably guided plunger having a reciprocating motion and provided
at its bottom end with a suitably recessed block or presser c, which by means of a
rod acted upon by a treadle can be pressed upon a horizontally adjustable block
or anvil fixed in the machine frame a and formed at its top end ' so as to
correspond with the recessed bottom end of the presser e, the arrangement being
such that a box provided witli a metallic angle piece m loosely fitted upon the same
can, when placed upon the said anvil k, be compressed between the same and the
presser substantially as described and shewn.
3: In a machine constructed' as described, the arrangement of bosses k² and of
corresponding recesses c on the two parts that are pressed against each other
(via the anvil and presser), the arrangement being such that when the sides of a
metallic angle piece m placed upon the corner of a box to be treated are compressed
between the anvil and pressér a secure fastening of the angle piece to the material
of the box is effected substantially in the manner described and shewn.
