Application March 27, 1937, vSerial No. 133,294‘
8 Claims. (Cl. 140—93)
This invention relates to box. making machin
ery and particularly to machines for equipping
wired box parts with fastening means.
It is an object of the invention to provide a
5 machine of the type shown in U. S. Patents Nos.
1,933,031 and 2,024,188, with mechanisms which
will permit it to operate on di?erent types of
box blanks and particularly upon ?breboard box
blanks having an overlapping ?ap at the closing
10 corner edge of the completed box.
One illustrative embodiment of the invention
is shown in the accompanying drawings, in
which:
Figure 1 is a perspective View of one type of
15 box blank upon. which the mechanism of this
invention is adapted to operate.

Fig. 2 is a perspective view of a completed box
made from the box blank shown in Fig. 1 and
showing the overlapping flap at‘ the closing cor
20 net of the box.
Fig. 3 is a side elevation of a fastener supply
ing machine equipped with the mechanism of
this invention. Certain parts are omitted for
clearness of illustration.

Fig. 4 is a plan view of the machine shown in
Fig. 3 with certain parts omitted for clearness
of illustration.
Fig. 5 is an enlarged side elevation of a por
tion of the machine of Fig. 3 and showing a box
30 blank being fed into the machine in the direc
tion of the arrow.
Fig. 6 is a similar view on a still larger scale
showing the position of the parts just prior to
?breboard. While a single sheet of side material
is shown in the illustrative box blank, it will be
understood that a plurality of sheets may be used.
The wires C are stapled to the box parts in a
box blank machine such, for example, as the 5
machine shown‘ in U. S. Patent No. 1,669,383 of
May 8, 1928. When the box blanks emerge from
the box blank machine they are connected to
gether by the wires $3, appropriate spaces being
left between succeeding 'box blanks to permit .10
severing the wires between blanks and forming
the fasteners D thereon.
The machine of this application receives the
wire-connected box blanks, severs the wires be
tween the blanks, forms prongs on the wire ends, 15 -
bends the wires to form the bights D, and drives
the prongs into the box parts to perpetuate the
bights D.
Referring to Figs. 1 and 2, the box blanks to
be operated upon are fed into: the machine onto 20
a table T which is reciprocated vertically to pre
sent the wires to the fastener supplying mecha
nism in the manner fully described in my Pat
ent No. 1,933,031.
‘
The box blanks are positioned on the table T IO 5
on stock supports I and are held against vertical
movement by presser bars 2. When the wire
connected box blanks have been correctly posi
tioned for a fastener supplying operation the
machine is started and one cycle of operation
severs all of the wires and forms bightsthereon,
all as fully described in said Patents Nos. 1,933,031
and 2,024,188.

terial A of the right hand end‘ of the blank which
constitutes the top of the box when the blank
is folded into box form is provided with an ex
50 tension or ?ap E which, as shown in Fig. 2, is
bent down over the front side of the box when
the blank is folded into box form.
