Improvements in Box Making Machines.
I, JOSEPH HENRY DANIEL REIBERGER, of 1209-1215 De Kalb Avenue, in the
City of Brooklyn, County of Kings, and State of New York, Paper Box Maker, 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:-
1-
My invention has reference to the manufacture of paper boxes, and the like.
The practice of my invention results in a method of manufacturing a box,
wherein a mandrel of the shape of the box in cross-section is covered with a strip
or band of paper card-board, or other material used in the manufacture of boxes,
and end pieces secured to the strip or band previously secured upon the mandrel,
and the box or dummy thus formed is then divided by severing the strip between
the end pieces to form the top and bottom of the box, to which is subsequently
added the interior flange, thus completing the box.
My invention therefor relates to a mechanical organization adapted to carry
out the beforementioned method; and it consists primarily in a suitably mounted
rotatable cutting knife or blade, and a bed and restraining guide for the support
of the box during the operation of severing the band to form two halves, which
bed or guide is conformed to the plane of movement of the box-dummy, which
bed can either be stationary, or segmentally disposed, (the curve of which will
then be concentric to the curve of the cutting knife) or said bed may be formed
of instrumentalities, forming a movable support for the box.
My invention further consists in the construction and combination of parts here-
inafter described, and further pointed out in the claims.
In the Drawings forming part of my application:
Figure 1 is a plan view of a machine, embodying my invention, said machine
being adapted for the manufacture of circular boxes; Figure 2 is a side elevation
of the same; Figure 3 is a front sectional elevation, taken on the line r, x,
Figure 2, looking in the direction of the arrow; Figure 4 is a diagrammatic view
of the cutting blade and box-dummy, illustrating the method of severing the
dummy into halves; Figure 5 is a side elevation of the dummy when severed
to form two box halves; Figure 6 is a sectional elevation through the dummy,
showing a mandrel within the dummy; Figure 7 is a side elevation of a portion
of the preferred form of cutting blade.
Similar numerals of reference indicate corresponding parts throughout the
several views.
In the manufacture of boxes, it has been customary to build up the box by
first forming two bands, as 1, Figure 5, then securing the pieces or heads 2 to
these bands, and finally securing to either of these bands on its inner surface,
another band, which fits into the band opposing it, thus completing the box.
It is the object of my invention to dispense with the independent formation of
these separate bands.
The description of my invention will hereinafter be applied to the construc-

page_text: tion of a single box, but it is apparent that it applies to the construction of a
number as well.
I form a mandrel, such as 3 Figure 6, preferably of wood or of any other
desired material, of a shape conforming to the interior cross-section of the box
to be produced, and about which the box is to be built up, I then take a single
strip or band 4 of material, such as paste-board and the like, and as wide as the
box and secure it about the edge or periphery of the mandrel.
In Figure 6 I have illustrated my invention in connection with the manu-
facture of a circular box so that the mandrel 3, shown therein is circular, and
the band 4, just beforementioned, is disposed around the periphery of the mandrel
and its ends secured.
To the edges of the band are then secured the end pieces such as illustrated
at 2 in Figure 5 and similarly lettered in Figure 6, and both the band 4, and end
pieces 2 may be covered by finishing material if desired.
This completes the dummy in which the mandrel is snugly encased.
The construction of a machine to properly sever the band 4 when circularly
disposed, in other words, the machine for operating on a circular mandrel is illus-
trated in Figures 1, 2 and 3, which I shall now describe:
To a suitable bed plate 5 is secured a pillar or standard 6 of which I may call
for brevity sake, a head stock, of any desired construction, preferably as shown in
the Drawing, wherein it comprises a central standard 7, base 8, head 9 longitu-
dinally grooved, and a cap 10 secured on the head by bolts 11. The base 8 is
secured to the bed-plate 5 in a similar way as by bolts 12.
The head 9 and cap 10 form a journal bearing for a shaft 13 to one end of which
is secured a hand wheel 14, the other end having an enlargement 15 carrying
a disk like head 16, to which is secured a circular blade 17 having a cutting
edge 18 by means of the detachable plate 19 and screw 20, which latter passes
through an aperture in the cutting blade.
The cutting blade 17 may be formed as desired, but I prefer the construction
shown in Figure 7 in which one side of the blade at the periphery is provided
with a long acute bevel a, and a short bevel b, which form the cutting edge 18.
The object of the long and short bevel of different planes is to make the blade
perform two functions, one of which) is the severance of the band 4, the other
is to give the dummy a movement transverse to its plane of rotation.
peculiar construction of the bevels enables the latter operation to be performed,
the former being accomplished by the cutting edge.
The
From the foregoing it is apparent that rotation can be given to the cutting
blade, either by the hand or by power, and that means are provided for supporting
the cutting blade and restraining longitudinal movement of its shaft.
The means for supporting the mandrel and box-dummy will now be described:
In front of the standard 7, (or head stock), the bed 5 is provided with a feather
or rib 21, over which is adapted to move a bracket or tail stock 22, comprising
a foot 23, groove d to receive the feather 21, as shown in Figure 2, and the per-
pendicular or abutment piece 24, to which is secured or formed the guide
block 25. The tail stock is adapted to be moved upon the bed 5 and feather 21
to bring the guide block 25 in or out of alignment with the cutting blade 17,
and to be secured in its proper relative position. To enable this latter to be
done I have provided the foot 23 with a threaded aperture in which is adapted
to play a threaded stem 26 having an operating handle 27, fixedly secured thereto
forming a clamp, which by turning will cause the threaded stem to impinge
against the feather 21 when it is desired to fix the head stock 22 in position, or
by reversing the movement of the handle 27 the stem 26 will be freed from the
contact with the feather to allow of the tail stock being moved.
By reference to Figure 3, it will be seen that the guide block 25 has a seg-
mentally formed ledge 28 formed concentric with the cutting blade 17, and
between the abutment 24 of the tail stock, and the ledge 28 is formed a channel
or groove 29, preferably following the curve of the ledge 28.

page_text: With a machine thus constructed, and a box dummy formed as previously
described, it is only necessary to bring the tail stock under the cutting blade,
adjusting the position of the guide block relative to the cutting blade that the
severance of the band 4 will be had at a suitable point between the end pieces 2,
the tail stock being then fixed in position by the means hereinbefore described,
at which time the machine is ready to operate upon the box dummy.
By reference to Figure 3 it will be seen that one end of the guide block 25
is cut away at 30 to form a mouth or opening, in which the box dummy is placed,
the mouth being extended by the inclined plate 30", secured to the guide block
by the flange 30%, the flanges or overlapping edge of the ends 2, embracing the
ledge 28 shown in Figure 2, confining the hereinafter described movement of
the dummy in a fixed circular line, and by pressing the dummy against the
cutting edge of the knife blade 17 either by hand, gravity, etc., and by rotating
the blade in the direction of the arrow, Figure 3, the cutting edge of the blade
will penetrate through the band, the band being supported by the mandrel 3,
the frictional contact of the parts moving the box dummy along the ledge 28
in the direction of the movement of the cutting blade rotating the dummy so
that the severance of the band 4 will be completed; the overlapping of the edges
of the end pieces 2 on the one hand, and the beforementioned action of the cutting
blade shown in Figure 7, on the other hand, keeping the dummy pressed against
the abutment 24 restraining longitudinal movement of the dummy, so that
aligned severance of the band will be had, the dummy ultimately being expelled
by the continuous rotation of the cutting blade from the supporting ledge 28 to 31,
at which time the severance of the band 4 as illustrated in Figure 5 has been
completed, after which the severed ends or heads (as they may be called) of the
dummy may be provided with interior bands, as hereinbefore described, to
complete the box.
The main essential feature of the device in this regard, it will be noticed,
consists in the formation of a bed or support for the mandrel and dummy,
coincident with the direction of their movement, which support, as before
described, can be either a stationary surface over which they roll, or which may
be combined with movable elements, in which may be included cutting instru-
mentalities.
From the foregoing, it will be seen that my invention can be carried out in
machines varying in structural character, the main essentials of which is a
rotatable severing or cutting blade, a bed, whereon the mandrel and dummy can
rotate either about a stationary point, or on a plane concentric with the edge of
the cutting blade, the plane of the bed being coincident to the plane of movement
of the mandrel and dummy, and means for guiding the mandrel during such
movement, and preventing it from becoming displaced during the cutting
operation.
Having now particularly described and ascertained the nature of the said
invention, and in what manner the said is to be performed, I declare that what I
claim is:-
First. In a box making machine, the combination of a cutting blade, a movable
