BOX ERECTING APPLIANCE
Harry A. Inman, Newark, N. Y.
Applicationliovember 4, 1937, Serial No. 172,861
14 Claim. (CI. 93-37)
This invention relates to an appliance for erect-v
ing boxes, and for purposes of illustration it is
embodied in a machine for erecting egg boxes
of a certain type, although the appliance is not
5 limited in its usefulness to the erection of such
boxes and it may be used for boxes intended for
holding various other articles also.
An object of the invention is the provision of
an improved and simpli?ed erecting appliance.
Another object is the provision of an appli
10
ance so constructed that, in one embodiment, it
has no moving parts whatever, and in another
embodiment has only a relatively few and simple
moving parts.
Still another object of the invention is the pro
vision of an erecting appliance so designed and
constructed that an unskilled person may easily
and quickly grasp the mode of operation of the
appliance and may readily become pro?cient in
20 using the appliance‘ to erect boxes.
‘
A further object of the invention is the pro
vision of an erecting appliance which is light'and
compact, ‘which is simple and. inexpensive to
construct, and which is sturdy and substantially
25 foolproof in use.
To these and other ends the invention resides
in certain improvements and combinations of
parts, all as will be hereinafter-more fully de
scribed, the novel features being pointed out in
30 the claims at the end of the speci?cation.
In the drawings:
Fig. 10 is a side view of the appliance with the
box or carton applied thereto in the stage next
following that shown in Fig. 9;

still later stage in the erection of the box;
Fig. 13 is a plan of the appliance and box at the
stage shown in Fig. 12;
Fig. 14 is an end view of the appliance and box
at the same stage shown in Figs. 12 and 13;
Fig. 15 is a view similar to Fig. 14, showing the
next following step or stage in the erection of the 15
carton, and
Fig. 16 is a section substantially on the line
lS-l 6 of Fig. 1, illustrating certain guiding posts
in elevation. >

The same reference numerals throughout the 20
several views indicate the same parts.
Referring ?rst to Figs. 1, 2, and 3, the appli
ance in its preferred form comprises a base plate
20 having at opposite ends ears 2i through which
screws 22 may extend to fasten the base plate
to any suitable table or other support 23. The
appliance is placed on the table so that the front
edge of the appliance slightly overhangs the front
edge of the table or projects frontwardly there
from, as shown in Figs. 1 and 3.

40 on the line 4-4 of Figs. 1 and 2, illustrating
32, 33, 34. and 35. The anvil 3| has a lower
portion 40 of somewhat trapezoidal horizontal
cross sectional shape, and above this lower por

bottom of the carton, since the carton is placed
upside down upon the appliance) and will depress
this carton top (really the bottom) along its
center line to perform one of the final stages in
‘the full erection of the carton.
A‘ number of separate arms may be secured’ to
working face 52 at a slight inclmation to a ver
tical plane, as best shown in Figs. 2 and 9. This
inclined face 52 is to contact with one edge of the
carton, in the manner described below.

preferabLv recessed or depressed to lie at a some
what lower elevation than that of the top of the
main ?at part of the base plate 20, rightwardly
of the guide member 32. Thus when the carton
is positioned on the appliance, the lower edge
of that part of the central partition to the left

bars or strips 9| and 92, approximately parallel
to‘ and slightly spaced from each other, are
mounted on the ends of the arms 86 and '1, so
that these bars will come down on the top of the
of the members 32 and ‘5 will not rest upon or rub
against the top surface of the base 2|, when the
rest of the partition is in contact with the base.

providing a leftwardly facing abutment surface above described, then the same depressing func
tion accomplished by these parts is done by hand,

These parts 2| to 82, inclusive, briefly described with the human ?ngers.

the box and the others being intermediate parti
tions dividing the length of the box into six com
partments. A central partition IIO divides each
of these six compartments into two compart
ments in a direction across the width of the box,
thus making twelve compartmentsin all in what
may be termed a 2 x 6 construction.
The parts ill to I03, inclusive, may all be
formed from a single integral piece of sheet ma
10 terial, such as carton stock, suitably cut, scored.
and folded. The central partition IIO may be
formed of a separate piece of such sheet material.
When the box is erected, a series of hooked tabs
II2 on the central longitudinal partition Ill ex
15 tend through suitably arranged openings II3
formed along the center line of the bottom of the
box, and interlocked with the edges of such open
ings II3, as shown in Fig. '7, in order to hold the
bottom in its intended position and to support
20 the center thereof at an elevation above the side
edges, to maintain the portions I03 and I04 at an
inclination, as shown. The downward pull of the
bottom upon the hooked tabs of the central parti
tion H0 is resisted by reason of the fact that the
partition I I0 extends over and is supported by the
cross partitions I08. which in turn are secured
at their ends to, and supported by, the front and
back walls IM and I02 of the box. The central
partition H0 is notched upwardly. from its bot
tom to receive the lower portions of the cross
partitions I03, while the cross partitions are
notched downwardly from their top edges to receive the upper un-notched part of the central
partition IIO. Interlocking lugs H5 on the cen
tral partition extend through holes in‘ adjacent
cross partitions to retain the central partition
against accidental removal from the cross parti
tions before the box has been erected.
3 ,
I03 and I04 are folded substantially against one
another as shown, in Fig. 6,- and extend down
wardly from the front and rear walls to the center
line of the bottom, instead of upwardly to the
center line as they do when erected in the position
shown in Fig. 8. ('I'hwe terms “downwardly”
and "upwardly" are used in the preceding sen
tence with reference to the upright normal posi
tion of the box, rather than with reference to its
inverted or upside down position shown in Figs. 10
5 to 8). In this collapsed position, each trans
verse partition I00 is folded upon itself along a
line formed approximately by the intersection
of each such transverse partition with the plane .
of the longitudinal partition, so that the trans 15
verse partitions are all doubled upon themselves
‘and the front and rear walls I0_I and I02 of the box
are brought relatively close to each other, occu
pying only a relatively thin space, as shown in
Fig. 6. The longitudinal partition H0 is dis
placed longitudinally to a substantial extent, as
shown in Fig. 5, and projects beyond the side
walls of the body at one end.
In erecting a box or carton of this kind with
this erecting appliance, the collapsed carton in the
form shown in Figs. 5 and 6 is grasped by an oper
ator standing or sitting immediately in front of
the appliance.- The operator places the-collapsed
carton in an upside down position as shown in
Figs. 5 and 6, and with the cover ?ap I05 on the 30
side of the carton closest to the operator. This
cover ?ap I05 is then placed substantially against
the front edge of the base plate 20 of the appli
ance, and the left hand edge of this cover ?ap is
brought against the stop III, the whole carton be
ing slightly tilted so that this left hand edge is
approximately at the inclination of the inclined
surface 52 on the stop 5|. This initial position
If desired, means may be provided for locking . of the parts is shown .in Fig. 9.
'I'heoperator then moves the upper left hand 40
40 the carton parts against accidental displacement
from normal erected position. One of the hook
tabs H2 (preferably the right hand one when
viewed as in Figs. '7 and 12) has its left edge
formed with portions I2I, I22, and I23 having the
45 relation to each other best understood by referring
to the drawings. For co peration with these
edges, the carton bottom‘se tions I03 and‘ I04 are
, provided, at the left end of the right hand slot
corner of the collapsed carton slightly away from
him or in a rearward direction with respect to
the erecting appliance, to position the slight space
between the walls ml and I02 of the carton di
rectly over the spreading anvil 3|. The carton 46
is then moved downwardly, holding it still at the
inclination shown in Fig. 9, so that the walls IM
and I02 pass down on opposite sides of the spread
ing anvil 3|, the wall I02 being to the front of
this spreading anvil and the wall IOI behind it.
The wedging action of the spreading anvil opens
II3,with portions I3I and I32 (Figs. 5, 7, l2, and
13) hinged to each other along the center line of
the bottom and hinged to the bottom sections I03
and I04 along the respective hinge lines I33 and , up the space between these walls and causes them
I34 approximately parallel to and spaced on op
to spread somewhat away from each other at their
posite sides of the center line of the bottom. The left hand ends.
In the initial downward movement of the car
ton, it is kept at substantially the same initial
inclination as shown in Fig. 9, the left hand edge
of the cover ?ap I05 and wall I02 riding down
the inclined surface 52. When the left hand
corner of the wall IOI ?nally strikes the top sur
face of the base plate 20, in the space between
erected position, the portions I3I and. I32 lie just the anvil 3| and the guide 30, the downward
to the left of and substantially in contact with movement of the left hand end of the carton is
the edge I23 of the central longitudinal partition completed. The operator now moves the right

swinging it down until the carton is in a horizontal
from moving leftwardly with relation to the car

tween the members 34 and 40 and between the
pairs of members 35. The wall IOI will come
down to the rear of these guides 32, 33, 34, and
35, since the initial. spreading of the walls by the,
, anvil 3| will be sufficient to open the walls far
enough so that the wall IIII will move down to
the rear of the member 32, and the inclined rear
edge of the member 32 will further force or cam
the wall IOI rearwardiy so that it will come down

action being assisted by the inclined rear edges
of the members 33 and 34.

edge of the wall I0| behind the abutment sur
face 3I, if necessary, although frequently this
left hand edge of the wall will itself spring behind
the abutment surface when it reaches it, without
needing much if any assistance from the oper
ator. The operator then releases the grip of
his right hand on the parts I03 and I04, and the
resilience of the transverse partitions II 0 holds
the left hand edge of the box blank against the 10
left hand abutment surface 5|, the parts now
being in the position shown in Figs, 12 and 13.
In this position, the walls IOI, I02, I03, and I04
are a little to the right of their normal erected
position with respect to the central partition 15

maintaining the central partition H0 in station

edges of the members 9i and 92 attached to these
arms, press downwardly along the center line of

from the upper position shown in Fig. 14 to the

the same way as is done by the hand of the

Then, while maintaining the parts I03,‘ I04 in

Those sides of the ‘members 32 and 45 which
are toward the central partition IIO are approx
imately ?at throughout the major portion of
their height, and make sharp corners with those
sides which are toward the cross partition with 35
which they engage, thus thrusting against the
cross partition at points close to the central par
tition and avoiding any. danger of bending the
cross partition and pulling it partly through the
space between the members 32 and 45, when the 40
central partition is tensioned.

By the use of the above described appliance in
either of its two forms, collapsed boxes or car
tons of the type here disclosed may be erected
easily and with great rapidity, by relatively un 45
skilled workers. The erecting appliance is not
on the longitudinal partition IIO, this erecting limited in its usefulness to cartons of this exact
appliance does not thrust against each transverse type, but may be employed also with various other

might bend or buckle it, but is under tension
caused by the tendency of the cross partitions
60 near the right end of the box to move the longi
tudinal partition rightwardly, which rightward
movement is resisted only by the second cross
partition from the left end, all of ‘the other cross
partitions being out of contact with the members
33, 34, and 35, as explained.
That part of the central longitudinal partition
‘ ‘I I0 which is to the left of the second cross par
titlon anchored by the members 32 and 45, will
be subjected to compression caused by the resist
70 ance which the first transverse partition from
the left offers to the effort to straighten it. The
degree of compression produced by this single
partition is relatively small, however, and is
adequately resisted by ‘the compressive strength
