Improvements in the Manufacture of Boxes, Saucers, Plates, and the
like, and Apparatus for the purpose.
I, JULIUS MOHS, of 76 Rosenstrasse Dresden, Saxony, Mechanical Engineer,
do hereby declare the nature of this invention to be as follows:-
My invention relates to the manufacture of angular boxes of cardboard, metal,
or other suitable material, in a more perfect manner than at present; and also to
apparatus for the purpose.
Parts of the apparatus are also applicable for making articles of other shapes,
such as round boxes, small trays or saucers, and plates.
In the processes hitherto adopted, angular boxes and the like have been
manufactured by means of a die or mandrel which determines the juncture of the
sides of the box with its ends, causing the edges of the sides to be connected with
the ends by glueing or otherwise, and which have to be bent inwardly at right
angles to the sides to enable the connection to be effected to enter into cavities in
the form of funnels with which the mould is provided, so that these edges are
gradually applied by folding back inwardly at a right-angle on the die whilst it
continues to advance; after this the latter continuing to enter into the mould, lays
the ends upon the folded back edges of the sides.
On account of these funnel-like pieces provided at the longitudinal edges at the
mouth of the mould, the ends of the box have necessarily to be cut to smaller
dimensions.
The result is that on each of the ends of the box two grooves are made forming
depressions behind the angles and allowing projecting parts between the said
grooves to appear on the outer surface of these ends. The projecting parts thus
formed on the ends are very detrimental to the appearance of the box.
According to my invention a box can be produced with a faultless exterior and
with perfectly smooth sides which come exactly flush with the angles. This is
effected by forming the mould without the funnel shaped cavities hereinabove
-mentioned and folding back the edges mechanically by means of angle-pieces or of
slides arranged on the interior of the mould. I am thus enabled to cut the ends of
the box from the sheet-of cardboard to exactly the size of the die. During the
entry of the die, arms or double angle-pieces with which it is provided come against
the slides or angle-pieces of the mould and cause them to approach one another and
gradually fold back the edges that are to be connected. After the folding back of
these edges at right-angles, the die, continuing to enter into the mould, turns down
the ends and places them against the edges to which they are.to be connected..
According to one arrangement for carrying my improved process into effect, the
sides of the mould are formed with recesses at the corners and in these recesses
angle-pieces are mounted. A. suitably shaped sheet of cardboard having been
placed on the mould, the entry of the die into the mould causes the sides of the
cardboard to turn up.
As the die continues to enter the moulds arms or brackets fixed to the said die
come against projections on the angle-pieces, causing the latter to turn and fold
back the edges to a right-angle.
The die continuing to enter the mould, the arms release the angle-pieces, which
then return into their original positions either by their own weight in the case of
vertical presses, and by mechanical means in the case of horizontal presses.
The continued movement of the die brings the cardboard against the extreme
end of the mould; the ends of the cardboard commence to rise, and during the

page_text: remainder of the movement they unite with the previously folded back edges, in
consequence of their pressure against the interior of the mould. On account of
the possibility of making the ends the same size as the mould the said ends present
an unbroken exterior surface which extends to the edges and does not contain any
projection or depression along the joined or connected edges such as has heretofore
been usual with boxes manufactured according to existing processes.
In place of the angle-pieces mounted on the mould for folding back the edges to
which the ends are to be connected at a right angle during the movement of the
die, I may employ slides which are furnished at their outer ends with projections
and are pressed outwards from the path of the die by spring plates. As the die
descends into the mould its arms come into contact with the projections and over-
coming. the pressure of the springs, move the slides inwards and thus cause the
edges to which the ends are to be connected to be folded back at a right angle."
In a modification fingers furnished with projections are substituted for the
aforesaid slides; these fingers are normally kept vertical by spring plates, whilst
during the descent of the die their upper ends are spread outwards so as to cause
their lower ends to approach each other and to fold the edges to which the ends
are to be connected back to a right angle as in the preceding arrangements.
...In another modification fingers or noses arranged to turn horizontally..are
mounted in the angles of the mould; the shorter ends of these fingers serve to fold
the required edges back to a right angle, when during the descent of the die, the
arms fixed on the latter come between and spread out the long ends of two
corresponding noses.
The above described process is applicable also to the manufacture of boxes from
thin metallic sheets, the edges of the boxes which are folded back in the manner
hereinbefore described, being fastened to the ends thereof by means of solder or in
any other suitable manner.
In carrying out the process according to this invention a direct action, derived
for example from the main shaft of the press, may, however, be employed to effect
the folding back of the edges, produced in the arrangements hereinbefore described
by the simple descent of the die actuating the angle pieces or their equivalents.
The arrangements hereinbefore described may be applied to existing machines
for making rectangular boxes out of sheets of cardboard which have been previously
cut out and coated with adhesive material on their edges, in which a crank imparts
a reciprocating motion to a die.
I will now proceed to describe a machine constructed according to this invention
for the manufacture of cardboard boxes or the like by my improved process.
The essential features of this machine are first the feeding of the cards from the
magazine to the die; secondly, the repetition of the pressure exercised by the die ;
thirdly, the maintenance of the pressure between the two applications of the die;
fourthly, the application of a disengaging apparatus of special construction; and
lastly, the application of motor mechanism calculated to double the output of the
machine.
The sheets of cut-out cardboard to be manufactured into boxes, plates or the
like are packed in a magazine under the pressure of a spring or counterweight.
They are fed from the magazine to the die by means of a plate which is
reciprocated by a lever in front of a socketed piece that carries both the magazine
and the die.
The lever is connected at one end with the plate and is caused to oscillate by
means of a cam.
In one of the positions of the plate, a perforated part of it which is covered
with a hood is brought in front of the magazine. Into this hood there opens a
steam pipe for the purpose of moistening the cards when the quality thereof
renders such treatment advantageous. In this position an opening in the plate,
around which there is a rebate corresponding to the size of the cut-out card
that it is to receive, is situated in front of the mould; the section of this opening
corresponds with that of the die which passes through it. The movement of the

page_text: plate is so arranged that in one of its extreme positions its opening is in front of
the magazine to receive one of the cut-out cards from the magazine into its
rebate after which it moves away with the card that it contains until it arrivés in
front of the mould, where it submits the card to the action of the die. After this
card has been transformed into a box, plate, or the like, the plate returns to
withdraw another card from the magazine.
The said magazine may be open at both ends or may be formed of bars arranged
to serve as guides to the cards.
In place of forming the plate with a rebate around the opening, the rebate
may be made in adjustable plates or bars which are arranged at the side of the
opening.
In another arrangement for feeding the cards from the magazine to the die, I
employ a disc pierced with several openings and capable of turning around its
centre. In this arrangement the axis of the magazine and that of the mould and
plunger are not situated in the same horizontal plane. After one of the cards has
been forced from the magazine into one of the openings of the disc, the latter
performs a partial rotation sufficient to carry the card to the front of the die.
In another modification instead of the rotating disc an oscillating plate is used
for transferring the cards from the magazine to the die.
The machine is provided with fast and loose pulleys and with a fly-wheel secured
on a sleeve on the driving shaft. On this sleeve is keyed a toothed wheel which
transmits its motion by means of gearing mounted on a counter-shaft to another.
wheel mounted on the driving shaft. The driving shaft is provided with crauks,
which are connected by rods to cranks on the aforesaid counter shaft. To the
cranks on the counter-shaft are also attached connecting-rods which at the other
end are jointed to the dies.
In a machine for making angular boxes, and in which the hereinbefore described
fingers are employed for turning back the edges that are to be connected to the
end, the mould is fitted into a socketed plate and the fingers turn in the interior of
the mould. On the end of the compression rod is mounted the die and the arms;
during the penetration of the die into the mould these arms cause the fingers to
turn so that the latter fold back the edges at the required moment. The mould
may be provided with an adjustable end for the die to press the card against.
This end and the regulating screw with which it is provided could in certain cases
be entirely omitted; for instance in the case of boxes with elevated sides. In this
case the mode of formation of an angular box may be like that which has just
been described; but when the die has a sufficiently long stroke it can push the
finished box through the open rear end of the mould.
Although the machine which has just been described has been fitted with one
of the devices hereinbefore described for turning back the edges, any of the other
devices herein described or any other mechanical combination capable of folding
back the edges-might be.applied thereto.
The adjustable end may also be employed-in-moulds used for making round
boxes.
The parts described above for actuating the die are so arranged that after
entering into the mould the die advances twice therein that is to say twice exercises
pressure on the article being manufactured; by this means much better defined
forms can be obtained. It is not necessary that the article being manufactured
should preserve its position after its first compression; it may, on the contrary,
be pushed back by the die and advance again afterwards before it is submitted to
the second compression. This movement of the box in the mould will improve its
exterior polish.
In making articles such as plates or other articles of open form, the entire
release of the pressure between the two periods of compression, that is to say at
the time when the die slightly retires, would be disadvantageous, as the form
produced during the first compression would disappear by the elasticity of the
material and great waste would be caused during the second period.

page_text: An arrangement has therefore been provided for maintaining the effect of the
compression during the interval which separates the two periods of compression.
To this end the die properly so called is made to work loose in the reciprocating
bar that carries it, and this bar is provided with a chamber into which the extremity
of the die enters and against which bears a strong spiral spring. The other end
of the spring bears against a nut which is adjustable on a screwed rod and this
screwed rod can be so regulated by means of the nut that its front end comes
against the extremity of the die when the die exercises its first compression.
When the bar containing the die afterwards slightly retires it does not carry the
die with it, the latter being kept by the spring with considerable pressure against
the article being manufactured up to the moment when the bar, advancing again,
effects the second compression by means of the screwed rod which presses against
the die.
In this way the undulations produced in the edge of the plate during the first
compression are preserved in the interior of the mould until the second com-
pression succeeds in giving to the article the form desired.
In order to remove the finished article from the die as the latter draws it with
it out of the mould I employ a doffing-apparatus composed principally of a frame
on which plates or bars can be adjusted radially in such a way that the extremities
of these plates which are turned towards the centre will cause the article to fall
off the die. This doffing-apparatus is equally applicable for round, oval and
rectangular articles.
My improved machine as above described may be arranged with the whole of
the apparatus on one side of the driving shaft or with two sets of apparatus one
on each side of the driving-shaft.

COMPLETE SPECIFICATION.
Improvements in the Manufacture of Boxes, Saucers, Plates, and the
like, and Apparatus for the purpose.
I, JULIUS MOHS, of 76 Rosenstrasse, Dresden, Saxony, Mechanical Engineer,
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:-
My invention relates to the manufacture of angular boxes of cardboard, metal,
or other suitable material, in a more perfect manner than at present; and also to
apparatus for the purpose. Parts of the apparatus are also applicable for making
articles of other shapes, such as round boxes, small trays or saucers and plates.
In the processes hitherto adopted, angular boxes and the like have been manu-
factured by means of a die or mandrel which determines the juncture of the sides
of the box with its ends, causing the edges of the sides which are to be connected
with the ends by glueing or otherwise and which have to be bent inwardly at right
angles to the sides to enable the connection to be effected, to enter into cavities in
the form of funnels, with which the mould is provided, in such a manner that these
edges are gradually applied by folding back inwardly at a right angle on the die
whilst the latter continues to advance, after which the die, continuing to enter into
the mould, lays the ends upon the folded-back edges of the sides.
On account of these funnel-like pieces provided at the longitudinal edges at the
mouth of the mould, the ends of the box have necessarily to be cut to smaller
dimensions. The result is that on each of the ends of the box, two grooves are
made, forming depressions behind the angles and allowing projecting parts between

page_text: the said grooves to appear on the outer surface of these ends. The projecting
parts thus formed on the ends are very detrimental to the appearance of the box.
According to my invention a box can be produced with a faultless exterior and
with perfectly smooth sides which will come exactly flush with the angles. This is
effected by forming the mould without the funnel-shaped cavities hereinabove
mentioned and by folding back the edges mechanically by means of angle-pieces or
of slides arranged on the interior of the mould. I am thus enabled to cut the ends
of the box from a sheet of cardboard to exactly the size of the die. During the
entry of the die, arms, or double angle-pieces with which it is provided, come
against the slides or angle-pieces of the mould and cause them to approach one
another and gradually fold back the edges that are to be connected. After the
folding back of these edges at right angles, the die, continuing to enter into the
mould, turns down the ends and places them against the edges to which they are
to be connected.
In the accompanying drawings,
Figs. 1 to 9 inclusive represent by way of example some devices for carrying
into effect my improved process of making angular boxes:
Fig. 1 shows partly in end elevation and partly in vertical section, one arrange-
ment of die block (hereinafter referred to as the mould) and punch or former
(hereinafter referred to as the die), the die being shown in a position in which it
has just commenced to fold back the sides of a box.
Fig. 2 shows a plan of the same.
Fig. 3 is a similar view to Fig. 1 but showing the die moved further into the
mould.
Fig. 4 shows a plan of the mould the piece of cardboard to be formed into a box
having just been placed thereon ;
Figs. 5 and 6 show partly in end elevation and partly in cross section modified
arrangements.
Figs. 7, 8 and 9 are respectively a partial end elevation, a sectional plan, and a
side elevation of another modified arrangement.
Referring to the arrangement shown in Figs. 1 and 2, the sides of the mould a
are formed at the corners with recesses b in which angle-pieces c are mounted. A
suitably shaped sheet of cardboard (the form of which is indicated in Fig. 4)
having been placed on the mould, the entry of the die e into the mould causes the
sides of the cardboard to turn up as shown in Fig. 1. As the die e continues to
enter the mould, arms or brackets el fixed to the said die, come against projec-
tions c¹, c² on the angle-pieces c and thereby cause the latter to turn and fold back
the edges d', d' of the sides d at right angles to the said sides as represented in
Fig. 3.
The die e continuing to enter the mould, the armis e¹ release the angle pieces c¹
and which return into their original positions, either by their own weight in the
case of vertical presses, or by mechanical means in the case of horizontal presses,
when the die e is raised.
The continued movement of the die e brings the end portions d' of the cardboard
-against-the-extreme-ends-of-the-mould-a-whereby-the-said-ends-d-are-folded-
upward and during the remainder of the downward movement of the die they are
united with the previously folded-back glueing edges d' and d³ in "consequence of
their being pressed against the interior of the mould. On account of the possibility
of making the ends d³ the same size as the mould, the said ends present an unbroken
exterior surface, which extend to the edges of the box and have no projection or
depression along the joined or connected edges such as has heretofore been usual
with boxes manufactured according to existing processes.
In place of the angle-pieces c mounted on the mould a for folding back the
edges d' and d² to which the ends d³ are to be connected at right-angles during the
downward movement of the die e, I may employ slides f (Fig. 5), which are
furnished at their outer ends with projections f¹, f2 and are normally pressed
outwards from the path of the die by spring plates f³, f. As the die e descends.

page_text: into the mould, its arms e¹ come into contact with the projections f¹, f' and, over-
coming the pressure of the springs, move the slides finwards and thus cause the
edges d'd to which the ends d³ of the box are to be connected, to be folded back
at right angles to the sides of the box.
In the modification shown in Fig. 6 fingers g furnished with projections g' are
substituted for the aforesaid slides. These fingers g are normally kept vertical by
spring plates g³, whilst during the inward motion of the die their upper ends are
forced apart so as to cause their lower ends to approach each other and so
fold the edges d', d² back at right-angles to the sides as in the preceding
arrangements.
In the modification represented in Figs. 7, 8, and 9, fingers h arranged to turn
horizontally, are mounted in the corners of the mould a; the shorter ends of the
fingers serve to fold back the required edges d', d², when, during the descent of
the die e, the arms e' fixed on the latter come between and spread out the long ends
of two corresponding fingers as shown in Fig. 9.
=
The hereinbefore described process is applicable also to the manufacture of boxes
from thin metallic sheets, the edges of the boxes that are folded back in the manner
herein before described, being fastened to the ends thereof by means of solder or
in any other suitable manner.
In carrying out the process hereinbefore described a direct action, derived for
example from the main shaft of the press, may, if desired be employed to effect.
the folding back of the edges, produced in the arrangements hereinbefore
described by the simple inward motion of the die actuating the angle-pieces or
their equivalents.
The arrangements hereinbefore described may be applied to existing machines
used for making rectangular boxes out of sheets of cardboard that have been
previously cut out and coated with adhesive material on their edges, and in which
a crank imparts a reciprocating motion to a die.
Figs. 10, 11 and 12 of the accompanying drawings illustrate a machine con-
structed according to this invention and suitable for the manufacture of cardboard
boxes or the like by my improved process,
Fig. 10 being a side elevation, partly in longitudinal section, and Fig. 11 a
sectional plan.
Fig. 12 is. a sectional plan of part of the machine drawn to a larger scale
and furnished by way of example with the arrangement of mould and die shown.
in Fig. 6.
The essential features of this machine are, first, the feeding of the cards from
the magazine to the die; secondly, the repetition of the pressure exercised by the
die; thirdly, the maintenance of the pressure between the two applications of the
die; fourthly, the application of a disengaging apparatus of special construction;
and, lastly, the application of motor-mechanism calculated to double the output of
the machine.
The sheets of cut out cardboard to be manufactured into boxes, plates, or the like
are packed in a magazine a under the pressure of a spring, or of a weight as shown.
They are fed from the magaziue to the die by means of a plate c which is recipro-
cated by a lever fin front of a socketed piece i which carries both the magazine a
and the mould d or d¹.
The lever is connected at one end by a link g with the plate c and is caused to
-oscillate about an axis g' by means of a grooved cam h.
In the extreme position of the plate c shown in Fig. 11, a perforated part of it,
which is covered with a hood e', is situate in front of the magazine a. Into the
hood c', there opens a steam pipe c² for the purpose of moistening the cards when
the quality thereof renders such treatment advantageous. In this position an
opening in the plate, around which there is a rebate corresponding to the size
of the cut-out card which it is to receive, is situated in front of the mould; the.
section of the opening c³ corresponds to that of the die e which subsequently passes
trough.it, when brought opposite the mould d. The movement of the piate is so

page_text: arranged that in one of its extreme positions its opening c³ is in front of. the
magazine a to receive one of the cut-out cards from such magazine into its rebate,
after which it moves away with the card that it contains until it arrives in front of
the mould d where it submits the card to the, action of the die e. After this card
has been transformed into a box, plate, or the like, the plate c returns to withdraw
another card from the magazine.
The magazine a may be open at both ends, as shown in Figs. 10 and 11; or it
may be formed of bars arranged to serve as guides to the cards, as shown
in Fig. 12.
As is shown to a larger scale in Figs. 13 and 14, the opening is.formed-in-a
removable plate, in which the rebate herein before mentioned is also made.. In
place of forming the plate with a rebate around the opening c³, the rebate may be
made in adjustable plates or bars d (Figs. 15 and 16) which are arranged at
opposite sides of the said opening.
.
In another arrangement, shown in Figs. 17, 18, and 19, for feeding the cards
from the magazine to the die, I employ a disc do pierced with several openings d³
and capable of turning around its centre d³. In this arrangement the axis of the
magazine a and that of the mould and die are not situate in the same horizontal
plane. After one of the cards has been forced from the magazine into one of the
openings d³ of the disc d', the latter performs a partial rotation sufficient to carry
the card to the front of the die.
In a modification represented in Fig. 20, instead of the rotating disc, an
oscillating plate d is used for transferring the cards from the magazine to the die;
this plate is recessed at d° and 10 and is oscillated to such an extent as to transfer
a card from d³ to d¹º.
The machine illustrated in Figs. 10 and 11 is provided with fast and loose
pulleys m and m² and with a fly-wheel m² secured on a sleeve m³ on the driving-
shaft n.
On this sleeve is keyed a toothed wheel m* which transmits its motion by
means of toothed wheels n¹ and o fixed on a counter-shaft o' to another wheel n²
mounted on the driving-shaft n. This driving-shaft is provided with cranks.
and, which are connected by rods p and p¹ to cranks o³ and os on the. aforesaid
counter-shaft o'. To the cranks o² and o are also attached connecting-rods & and is¹
which at their other ends are jointed to the dies e and e¹.
In Fig. 12 the machine is represented as adapted for making angular boxes and
as provided with the arrangement hereinbefore described with reference to Fig. 6
for turning back the edges that are to be connected to the end of the box, the
mould a being fitted into the socketed plate i and the fingers g' being adapted to
turn in the interior of the mould. On the end of the compression-rod is mounted
the die e (Fig. 12) and the arms e'; during the penetration of the die into the
mould the arms el cause the fingers g to turn in such a manner that the latter fold
back the edges at the required moment.
The mould a may be provided with an adjustable end d for the die to press
the card against. This end d and the regulating screw with which it is provided,
could in certain cases be entirely omitted; for instance, in the case of boxes with
elevated sides. In this case the mode of formation of an angular box may be like
that hereinbefore described, but when the die has a sufficiently long stroke it can
push the finished box through the rear end of the mould when the end of the mould
is omitted.
Although the machine which has just been described has been fitted with the
device represented in Fig. 6, for turning back the edges any of the other devices
hereinbefore described, or any other mechanical combination capable of folding
back the edges, might be applied thereto.
One of the moulds adapted for making round boxes, shown in Fig. 11, is provided
with a piston or end d adjustable from behind.
The parts hereinbefore described for actuating the die are so arranged that after
entering into the mould, the die advances twice therein, that is to say, twice
exercises pressure on the article being manufactured; by this means much better

page_text: defined forms can be obtained. It is not necessary that the article being manu-
factured should preserve its position after its first compression; it may, on the
contrary, be pushed back by the die and advance again afterwards before it is
submitted to the second compression. This movement of the box in the mould will
improve its exterior polish.
In making articles such as plates or other articles of open form, the entire
release of the pressure between the two periods of compression, that is to say at the
time when the die slightly retires, would be disadvantageous, as the form produced
during the first compression would disappear by the elasticity of the material and
great waste would be caused during the second period.
An arrangement has therefore been provided for maintaining the effect of the
compression during the interval which separates the two periods of compression.
To this end the die properly so called is made to work loose in the reciprocating
bar (Figs. 10 and 11) that carries it, and this bar is provided with a chamber into
which the extremity e³ of the die e' enters and against which bears a strong spiral
spring. The other end of this spring 63 bears against a nut e' which is adjustable
on a screwed rode which can be so regulated by means of the nut e that its front
end comes against the extremity of the die when the die exercises its first
compression.
When the bar containing the die afterwards slightly retires, it does not carry the
die with it, the latter being held by the spring e³ with considerable pressure against
the article being manufactured up to the moment when the bar, advancing again,
effects the second compression by means of the screwed rod et, which then presses
against the extremity of the die.
In this way the undulations produced in the edge of the plate during the first
compression, are preserved in the interior of the mould until the second compression
succeeds in giving to the article the form desired.
In order to remove the finished article from the die as the latter draws it out of
the mould, I employ a doffing-apparatus which is represented in Fig. 21 and is
principally composed of a frame on which plates or bars v¹, one of which is shown
detached and to a larger scale in Fig. 22, can be adjusted radially in such a manner
that the extremities of these plates which are turned towards the centre, will cause
the article to fall off the die. This doffing-apparatus is equally applicable for
round, oval, and rectangular articles.
Instead of arranging my improved machine with the whole of the apparatus on
one side of the driving-shaft as represented in Figs. 10 and 11 it may be arranged
with two sets of apparatus, one on each side of the driving-shaft, as represented
diagrammatically in Fig. 23.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
