Board and the like for the Manufacture of Boxes.
I HUGO BREHMER of Plagwitz in the Kingdom of Saxony, Manufacturer 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 the stamping out or cutting of pasteboard or the like so
that boxes may be made therefrom.
The machinery for effecting this purpose represented in the accompanying
drawings serves generally for stamping out any suitable parts or shapes from paste
board or other similar material. In the following description however special
reference is made to the application of the devices for stamping the parts of the
folding box represented by Figs. 8 to 13-of which Figs. 9 to 13 show successive
stages in the process of building up the box.
In the frame G¹ Figs. 1 and 2. two shafts A A¹ are so journalled that the spur
wheels a al of equal diameter and secured respectively one on each of the shafts A A¹
are exactly geared with each other without play. On each of the two shafts are
situated two tubes B D F H which are displaceable thereon but prevented from any
turning by wedges or feathers b b¹. In the same manner each of these four
tubes B D F H carries on its long nave another tube C E GJ respectively which
is provided with set screws by means of which the tubes CEG J can be fixed on
the tubes B D E H and at the same time the latter on the shafts.
The two pairs of tubes B C and D E on the upper shaft are intended for the
reception of the matrices and the dies are supported by the tube pairs F G and H J
of the lower shaft.
The manner of securing the matrices as well as the dies allows as shown in
Figs. 6 and
of a displacement of the same on the circumference of the tubes in the
direction of their revolution; thus the distance of two dies or matrices from each
other can be increased or decreased.
For the purpose of stamping or cutting out the parts of paste board boxes shown
in Fig. 8 dies of three different shapes are employed viz., for the long parts LL LL
the four dies are employed for the parts M M the two dies m m and for the

page_text: parts N N the two dies n n. These eight dies are so arranged in pairs on the circum-
ference of the four tubes, that the parts shown in Fig. 9 required for a box of the
kind mentioned above can be produced.
The tube G Fig. 6 carries beside the dies and m a knife k inclined to the axis of
the shaft by which knife the cut K Fig. 8 is executed by being pressed obtusely
against the circumferential surface of the opposite tube C.
The same system of dies and knives required for producing the closing end of a
paste board box as abovementioned is also provided symmetrically to the above
system at the circumferences of the tubes F G H J producing the other closing end
of the box, therefore the parts shown in Fig. 8 are produced twice with one revolution
of the shafts.
As mentioned above, these two systems owing to the manner of securing the
single dies can be displaced on the tubes and the latter on the shafts in themselves
as well as relatively to each other as may be required for producing boxes of various
shapes.
The four upper tubes each carry two matrico holders 00 Fig. 6 which are dis-
placeable corresponding to the die of the lower shaft. These tubes B C D E are
provided on their circumference with steel rings the rims of which together
with the rims of the steel bows ssss situated on the circumference of the matrice
holders from the matrices for the-long dies 11 11.
In the steel bows of the matrice holders are contained the matrices corresponding to
the dies m m and n n respectively.
To prevent the sheet of paste board from adhering to and being taken along by the
dies one or more strippers or guards p are provided for each of the four rows of dies,
which strippers, as represented by Fig. 7 cause the sheet to glide off the dies on the
further revolution of the shafts.
These strippers or guards are secured by set screws to the bar q situated
'parallel to the axes of the shafts so as to allow them to follow the four tubes on
the displacement of the latter in the direction of the axes of the shafts. In the
same manner four ploughs p¹ are provided on the bar g so that by passing through
between the steel rings rrrr of the tubes B C D E and the steel bows ssss
of the matrice holders said ploughs remove the long cut off portions L L L'L from
out of the matrices, and cause such removed portions to pass into a trough or
holder R Fig. 1. The scorings K' may be made by suitable dies or by hand.
The paste board is automatically supplied to the machine at the proper moment.
For this purpose the lower shaft carries a cam disc S Figs. 1 and 2 which
causes the angle lever T provided with counterpoise to move to and fro, the said
angle lever having a roller on one of its arms and bearing on the cam therewith,
this to and fro movement being transmitted by rod U and lever to the axle W
and lever X secured thereto. To this lever Xa long slide piece Y is secured by
means of a connecting rod said slide piece being guided in a slot in the table plate
of the machine so that on the revolution of the shafts it slides to and fro in the
same. On this slide piece Y is displaceably arranged the sliding block z which, when
the machine is at work leads the piece of paste board laid before it to the shafts which
sieze said piece by means of a rubber edging cc provided on the tubes and
operate on the same in the manner described. To give the piece of paste board
the proper lateral position and direction for introduction between the shafts two
guides and Fig. 3 are displaceably arranged in a groove in the table plate.
x Figs. 11, 12 and 13 are wire staples for fastening the box.
Having now particularly described and ascertained the nature of any said
invention and in what manner the same is to be performed I declare that
what I claim is :-
In a machine for cutting out paste board for folding boxes.
1. The combination with the shafts A A¹ of tubes B D F H capable of sliding
thereon, tubes E G J respectively on said tubes B D F H said tubes carrying dies
and matrices for the purpose set forth.

page_text: 2. The combination with rotary tubes, shafts or equivalents, of dies and
matrices thereon displaceable back and forth in the direction of rotation of said tubes
or the like.
3. The combination substantially as set forth of the dies l m n and the respective
matrices therefor.
4. The combination with dies and matrices arranged to operate substantially as set
forth of cleaners p' adapted to remove portions of paste board disconnected from the
inain piece, from out of the matrices.
5. The combination with dies and matrices arranged to operate substantially as set
forth of block z, cam S and suitable lever gear substantially as described.
