Improvements in Machinery for Cutting Up Cardboard and other
like Cylinders for Forming Circular Boxes.
We, LEOPOLD MYERS, of Charlotte Street, Birmingham, Warwickshire, Pen
Manufacturer, and CHARLES BOSWORTH KETLEY, of 128, Colmore Row,
Birmingham, aforesaid, Engineer and Patent Agent, do hereby declare the nature
of this invention to be as follows:-
This invention consists of the hereindescribed improvements in machinery for
cutting up hollow cylinders of cardboard or other like hard material into short
lengths for forming circular boxes.
In carrying out this invention we provide a number of circular cutters mounted
ou a spindle revolving rapidly in bearings in the framework of the machine. These
cutters are equal in number to the number of cuts or divisions required in the
cardboard or other like cylinders and they are fixed the proper distances apart on
their spindle by washers or distance blocks between them. Parallel with the
cutter spindle we provide four (or there may be fewer or more than four) mandrels
preferably made of wood arranged round the cutters in a circle at equal distances
apart so as not to touch the cutters. Each of these inandrels is provided at one end
with a cylindrical metal collar or holder into which the mandrel fits tightly and to
which it is secured by a nut or other means. These holders are carried by a chuck
which receives intermittent rotary motion round the cutter spindle, moving a fourth
of a revolution at once and then stopping which is accomplished by a pawl engaging
in one of four teeth or rollers round the chuck the pawl receiving motion through
a lever from a cam on a revolving cam shaft. To ensure the said mandrels being
held in the chuck parallel with the cutter spindle and allowing of their being moved
to or from the cutters, as hereinafter described, each of the cylindrical holders of
the mandrels fits in a slot or groove in the chuck where it is held by an eye through
which it passes, this eye having a shank which passes through a hole in the chuck.
The axes of these shanks are produced radii of the chuck. Each shank has at its
end a set screw for the purposes hereinafter described, and a washer between which
latter and the chuck is a coiled spring which forces the shank outwardly and holds
the said holder in the groove. When the chuck is at rest we prefer for one of the
mandrels to be underneath the cutter spindle on its vertical centre line. A suitable
locking arrangement, such as a spring slide acting upon two of the rollers on the
chuck is provided to lock the chuck in this position until its pawl is ready to move
it forward again. The said wooden mandrels are made a little longer than the
hollow cardboard cylinders which are required to be cut up and of such a diameter
that the said cylinders will fit easily thereon. The cylinders are fed on to the
wooden mandrels in succession as the latter arrive say on the left hand side of the
machine. This feeding of the cylinders on to the mandrels may be done by hand
or by a feeding device which is preferably constructed as follows:-The cylinders
are placed in a hopper one above the other in a horizontal direction the bottom
cylinder being directly in a line with the mandrel on to which it is pushed by a
slide moving to and fro at the bottom of the hopper, this slide receiving motion by
a lever and cam on the revolving cam shaft above mentioned.
Whilst the bottom
cylinder is being fed on to the mandrel the other cylinders are maintained in a
horizontal position in the hopper and prevented from getting askew by a thin
horizontal plate which is moved to and fro by a cam on the said cam shaft. This

page_text: plate is moved in between the bottom cylinder and the next one above it when the
bottom cylinder is being pushed on to the mandrel and when the feed slide bas
returned and is at rest the said plate is moved from beneath the cylinders and allows
another one to move down ready to be fed on to the next mandrel. An adjustable
stop is provided on the machine frame against which the ends of the cylinders are
fed so as to prevent their being pushed too far on to the mandrels.
Beneath the cutter spindle and parallel with it are two rollers side by side one
on either side of the vertical centre line of the spindle preferably of larger diameter
than the mandrels. These rollers are free to revolve in bearings provided in slides
which for the purpose hereinafter described are moved to and from the cutter
spindle along suitable guides by cams on the said cam shaft. On one of these slides
is a projecting piece which when the rollers are moved upwards towards the cutters
as hereinafter described strikes the set screw on one of the said shanks and moves it
upwards with the mandrel so that the rollers and that mandrel move up towards the
cutters together, the mandrel being partly between but above the centre of the
rollers. The said set screws in the ends of the shanks have to be so adjusted that
the cylinder on the mandrel will just touch and lie evenly along the rollers.
On
The operation of the machine as above in part described is as follows:-The
cutter shaft and the cam shaft having been set in motion then while the chuck is
stationary a cylinder is pushed on to one of the mandrels by hand or by the feed
slide above described; the chuck with the four mandrels now turns round through a
fourth of a revolution thus bringing the mandrel on which is the cylinder to the
lowest position below the cutter spindle. On the chuck coming to rest the two
rollers are moved upwards, as above described, carrying with them the cylinder
having the mandrel inside it, which they press against the revolving cutters.
the cylinder touching the revolving cutters it is by them caused to revolve and its
rotary motion is transmitted to the rollers so that the cutters, cylinder, mandrel and
rollers all revolve together. The said cams which actuate the rollers are made of
such a shape that after the cylinder has come into contact with the revolving
cutters it is pressed against them gradually until the cutters have passed right
through the cylinder and severed it into short lengths. The rollers now move
downwards to their normal position the spring on the shank bringing down the
mandrel and divided cylinder also until its holder rests in its groove in the chuck.
Whilst this cylinder has been divided by the cutters another cylinder has been fed
on to the next mandrel by hand or by the feeding device above described. The
chuck now moves again through a fourth of a revolution and comes to rest thus
bringing the first mandrel on which is the divided cylinder in position for the short
lengths of the cylinder to be stripped off by the device which we will now describe.
A hooked piece is provided on a sliding block moving to and fro along a guide or
guides parallel with the mandrel by means of a lever and cam on the said cam
shaft. When this block is in its normal position it is near to the chuck so that
when the mandrel with the divided cylinder comes to rest it is embraced by the
hooked piece between the end of the cylinder and the holder. When the chuck is
at rest the hooked piece is moved forward towards the fore end of the mandrel thus
stripping the pieces or short cylinders off the mandrel which fall down a shoot into
a suitable receptacle. The sliding block rests in its forward position until the
mandrel has passed when it returns to its normal position ready to engage with the
next mandrel. Whilst the divided cylinder is being stripped from the first mandrel
as above described a cylinder on the second mandrel is being divided by the cutters
and another cylinder is being fed on to the third or fourth mandrel the three
operations taking place simultaneously.
We prefer to cover the said rollers with india rubber so as to obtain a more
even bearing on the cylinders.
The slides which carry the rollers are provided with a screw or other adjustment
by which the distance of the rollers from the cutters can be adjusted as required
so as to regulate the depth of cut and ensure the cutters not cutting far into the
mandrels.

page_text: The different moving parts of the machine may either receive motion from a
single shaft or from several shafts secured together.

Improvements in Machinery for Cutting up Cardboard and other
like Cylinders for Forming Circular Boxes.
We, LEOPOLD MYERS, of Charlotte Street, Birmingham, Warwickshire, Pen
Manufacturer, and CHARLES BOSWORTH KETLEY, of 128, Colmore Row,
Birmingham, aforesaid, Engineer and Patent Agent, 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 consists of the herein described improvements in machinery for
cutting up hollow cylinders' of cardboard or other like hard material in short
lengths for forming circular boxes such as pill boxes, cartridge cases, match boxes
and others. We will describe our invention by referring to the accompanying

Fig. 15 is a separate view of the appliance which removes the cardboard
cylinders from the mandrels as aforesaid;
Fig. 16 shews one of the cardboard cylinders which are cut up by the machine
into small pieces such as shewn by Fig. 17.
The same letters of reference indicate the same parts in all the figures of the
drawings.
In carrying out this invention we provide a number of circular cutters marked a
mounted on the horizontal spindle A which by a band driving on to the pulley a*
fixed on the spindle A, is caused to revolve rapidly in the bearings & carried by
the framework B of the machine. These cutters a' are equal in number to the
number of cuts or divisions in the cardboard or other like cylinders, in this case
seventeen in number but there may be either more or fewer than seventeen
according to the number of pieces into which the cylinders are to be cut. The
said cutters a are fixed the proper distances apart on the spindle A by washers

page_text: or distance blocks a³ threaded on the spindle A between the cutters a¹. Parallel
with the cutter spindle A we provide four (or there may be fewer or more than
four) mandrels marked C' C2 C3 C which are by preference brass tubes of a size
to fit easily in the cardboard cylinders (or the mandrels may be made of wood or
other suitable substance) arranged round the cutters a' in a circle (see Fig. 10)
at equal distances apart so as not to touch the cutters a'. Each of these
mandrels C¹ C³ C³ C* is provided at one end with a metal collar or holder c¹
shewn separately by Fig. 12* into which the mandrel fits tightly and to which the
mandrel is secured by any convenient means as for instance by the holder c¹ being
slit or divided longitudinally for a certain distance from one end and upon this end
a collar c² is screwed this collar being split at one side (see Figs. 6, 8, 10 and 12)
and clamped together by a set screw c³ so as to close the holder c¹ on the mandrel
and thus secure the collar to the mandrel but permit of the mandrel being adjusted
longitudinally in the holder c¹ and fixed in various positions therein so that when
the mandrels have become grooved by the constant action of the cutters the
collars can be loosened and the mandrels moved either farther in or out of their
holders so as to bring a fresh part of the mandrels for the cutters to act upon.
These holders c' are carried by the chuck or casting D which as hereinafter
described is caused to rotate intermittently round the boss 62 of the bracket B' in
which the spindle A revolves, this chuck D being concentric with the cutter
spindle A. The chuck D together with the mandrels C' C2 C3 C* carried thereby
receive intermittent rotary motion round the cutter spindle A, moving a fourth of
a revolution at once and then stopping, which is accomplished by any convenient
mechanism, such for instance as the hooked pawl E¹ (see Figs. 1, 2, 3, 4 and 5)
engaging with one of four rollers d' d² d³ d fixed to the chuck D, the pawl El
receiving up and down motion through the lever E which turns on a fulcrum e¹
and is acted upon by the cam E³ fixed on the revolving cam shaft F which latter
receives rotary motion through the spur wheels f¹ from the pulley f3 which
latter together with the spur wheel f' revolves loosely about the cutter spindle A
see Fig. 1.
When the hooked pawl E¹ is by the cam E³ moved down from its
highest position shewn in Fig. 4 the hooked part engages with one of the rollers
say d³ of the chuck D and turns the chuck through a fourth of a revolution its
motion being arrested and the chuck held in the position shewn by Fig. 4 by the
Tshaped spring slide G which is forced upwardly by the spring gl so that this
slide G bears against two of the rollers such as d' d' see Fig. 4 and thus maintains
the chuck or casting D and the mandrels C' C2 C3 C₁ carried thereby in position
whilst the various operations of feeding one of the cardboard cylinders on to one
of the mandrels, bringing another of the mandrels and the cardboard cylinder
thereon up to the cutters and cutting the same, and the stripping off of the divided
cylinder from another mandrel, as hereinafter described, is taking place. The up
stroke of the lever E' and hooked pawl E' is caused by the spring U (Fig. 3). To
ensure the mandrels C1 C2 C3 C₁ being held in the chuck D parallel with the cutter
spindle A and allowing of the mandrels being moved to and from the cutters a¹ as
hereinafter described, each of these cylindrical mandrel holders c' fits in a radial
slot or groove in the chuck these slots or grooves being marked respec-
tively do do d' d8 and each of the mandrel holders is held in its slot by a metal
eye H shewn separately by Fig. 12 through which the holder c¹ passes each of
these eyes H being made with a shank h' which as shewn in Figs. 6 and 8 passes
through a hole d in the chuck D. Each of the shanks h¹ has a set screw h² at
its outer end for the purposes hereinafter described and a washer h³ between which
latter and the chuck D there is a coiled spring d¹0 threaded on to the shank h¹ and
which acts between the washer h³ and the chuck D and forces the shank /' out-
wardly thus firmly holding the mandrel holder c¹ in its corresponding groove in the
chuck D as shewn in Figs. 6 and 8. The mandrel holder c' is prevented from
moving endwise by its two collars c c bearing against the chuck. When the
chuck D is at rest one of the mandrels C1 C2 C3 C is underneath the cutter
spindle A on its vertical centre line the slide G acting upon two of the

page_text: rollers d' d d d on the chuck as stated above so as to lock the chuck D in this
position until the pawl E' is ready to move forward again. The mandrels C¹ C³ C³ C*
are made longer than the hollow cardboard cylinders I which are required to be
cut up and of such a diameter that the said cylinders I will fit easily thereon.
The cylinders I are pushed on to the mandrels C C C C in succession by hand
as the latter arrive at say the top of the machine, that is to say, the mandrel C¹
shewn in Figs. 1, 2, 3, 4, 6, 7, 8 and 9 is in the best position for feeding one of the
cardboard cylinders upon it these cardboard cylinders being held on a slanting
table or receptacle such for instance as that shewn on the drawings and marked J.
Beneath the cutter spindle A and parallel with it there are two rollers marked
respectively K¹ K2 side by side one on either side of the vertical centre line of the
spindle A and preferably of larger diameter than the mandrels C¹C² C³ C. These
rollers K K are free to revolve in bearings provided in the two slides L' L'
which for the purpose hereinafter described are moved alternately towards and
away from the cutter spindle A along the vertical guides 636 provided on the
framework B of the machine the said slides L' L' being moved up see Fig. 8 by
the cams M M2 ou the cam shaft F at the proper time as hereinafter described
and falling at the proper time to the position shewn by Fig. 6 when the cam
shaft F is turned round somewhat. Fixed to the slide L2 there is a side projecting
piece 3, see Figs. 6 and 8, which when the rollers K' K² are by the cams M' M² moved
upwards towards the cutters a' as hereinafter described, strikes the set screw h²
on one of the shanks and moves the shank h¹ and its eye H upwardly with
the mandrel C³ so that (as shewn in Figs. 8 and 9) the rollers K K² and the
mandrel C³ moved up parallel together towards the cutters a¹ the mandrel C³ being
as shewn by Fig. 9 partly between but above the centre of the rollers K¹ K².
The said set screws in the ends of the shanks have to be so adjusted that the
cardboard cylinder I on the mandrel C³ will just touch and lie evenly along the
rollers KK.
The operation of the machine as above in part described is as follows:- - When
the machine is in motion the cutter shaft A with the cutters revolves rapidly say
at about a speed of six hundred or seven hundred revolutions per minute and the
cam shaft F revolves at a speed of fifteen revolutions more or less in the direction
shewn by the arrows in Figs. 1, 3, 4, 5, 7, 8 and 9. These speeds we have found
to answer well in practice. While the chuck D is stationary the person who is
minding the machine takes one of the cardboard cylinders I from the table J and
pushes it on to the top mandrel C¹ the stationary cross bar N fixed to the
bracket O' (which latter is bolted to the machine frame B) acting as a stop to
prevent the cardboard cylinder J being pushed on too far. Or instead of pushing
the cardboard cylinder on to the top mandrel C' the attendant may push the card-
board cylinder on to the other mandrel C². The cam E³ now depresses the
lever E and the hooked pawl E' which latter engaging with one of the
rollers d' d² d³ d on the chuck D (see Fig. 5.) turns the chuck D through a fourth
of a revolution thus bringing the mandrel C³ on which is the cylinder I to the
lowest position below the cutter spindle as shewn in Fig. 7. On the chuck D
coming to rest and being there held by the slide G the two rollers K' K² are by
the cams M' M² acting on the slides L' L³ moved upwardly as above described,
the side projection moving up the eye H and its shank and the mandrel c³
with the cylinder I upon it which cylinder the rollers K¹ K² press against the
revolving cutters a¹ as shewn in Fig. 9. Immediately the cardboard cylinder I
O touches the revolving cutters a' as shewn in Fig. 9 the cylinder I with the
mandrel C³ and its holder c' is by the cutters caused to revolve rapidly and its
rotary motion is transmitted to the rollers K' K' so that the cutters a' cylinder [
mandrel C³ and rollers K' K² all revolve together. The cams M' M² which actuate
the rollers K1 K2 are made of the shape shewn in Figs. 11, 7 and 9 so that after
the cylinder I has come into contact with the revolving cutters a¹ it is by the
rollers K' K² pressed against the cutters a gradually until the cutters have passed
right through the cylinder I and severed it into short lengths such as shewn by

page_text: Fig. 17. The drop m' in the cams M¹ M² now causes the slides L' L² of the
rilers K K² to move downwards to their normal position shewn in Fig. 6.the
spring d on the shank bringing down the mandrel C³ and divided cylinder I
also until the mandrel holder c¹ rests in its groove in the chuck D. Whilst the
cylinder I has been divided by the cutters a' as above described another cardboard
cylinder has by the attendant been placed on to the next mandrel. The chuck D
is now by the hooked ratchet E' above described caused to move again through
another fourth of a revolution and by the Ṭ slide G to be brought to rest thus
bringing the first mandrel C³ on which is the divided cylinder into the position
which was previously occupied by the mandrel C in Figs. 7 and 9 so that the
short lengths of the cardboard cylinder will be ready to be stripped off the mandrel
by the stripping device which we will now describe. This stripping device consists
of a hooked piece of metal P which is fixed on a sliding block p' arranged to slide
to and fro along the guide bars p² p³ parallel with the mandrel which guide bars
are carried by the brackets 0' 02 fixed to the frame B of the machine. This
hooked piece P is made of such a size at p' to fit on to one of the mandrels against
the end of the cardboard cylinder 1. The sliding block p' is moved to and fro by
the lever Q this lever Q being moved in the direction away from the chuck D
by the cam q¹ fixed on the revolving cam shaft F and is moved in the direction
towards the chuck D by means of the coiled spring q' fixed to the lever Q and to a
pin on the frame of the machine. When this block p' is in its normal position
shewn by Fig. 13 it is near to the chuck D so that when one of the mandrels with
the divided cylinder I comes to rest the mandrel is embraced by the hooked
piece P between the end of the cardboard cylinder I and the collar c² of the
mandrel holder. Whilst the chuck D is at rest and one of the cardboard cylinders
is being cut and divided as aforesaid the hooked piece p is by the cam g' and
lever moved forward towards the fore-end of the mandrel see Fig. 14 thus
stripping the pieces or short cylinders & off the mandrel which small cylinders fall
down a shoot r into a suitable receptacle. The gradual inclined portion 93 of the
cam q¹ causes the forward motion of the lever Q as aforesaid and when the sliding
block P has arrived at its extreme forward position it is by the flat part q* of the
cam g¹ caused to rest in this position until the chuck D has turned through about
an eighth of a revolution to the position shewn by Fig. 5 so that the mandrels will
then be clear of the slide P which the suddenly inclined portion 9³ of the cam q¹
allows to then be returned to its normal position by the spring q' ready to engage
with the next mandrel. It will be seen that the cam E³ which operates the lever E¹
for turning over the chuck is made with a short period of rest at e² so as to allow
of the chuck D remaining stationary in the position shewn by Fig. 5 for a short
period of time as aforesaid whilst the slide P is returning to its normal position
shewn by Fig 13.
1
Whilst the divided cylinder I is being stripped from one mandrel as above
described another cylinder on the next mandrel is being divided by the cutters a¹
as aforesaid and another cylinder is being placed on to the third or fourth mandrel
the three operations of placing a cardboard cylinder on the mandrel, cutting up the
cardboard cylinder, and stripping the cut cylinder off the mandrel, taking place
simultaneously.
The rollers K1 K2 are by preference covered with india rubber so as to obtain a
more even bearing on the cardboard cylinder I. The slides L' L² which carry the
rollers K¹ K² are provided at their lower ends with a screw adjustments by which
the distance of the rollers K' K* from the cutters a¹ can be adjusted as required so
as to regulate the depth of cut and ensure the cutters not cutting too far into the
mandrels.
In conclusion we wish it to be understood that the various arrangements of
mechanism illustrated on our drawings are what we have found best for performing
the various operations but it will be understood that our invention is not limited to
the precise forms of mechanism shewn as these might be varied without departing
from the nature of our invention or affecting the operation of the machine.
We

page_text: might for instance construct the chuck D to carry fewer or more than four
mandrels.
In order to prevent the operator's fingers coming in contact with these revolving
cutters a whilst the operator is pushing one of the cardboard or other like cylinders
on to the mandrel we provide a thin sheet metal cover W which is shewn in cross
section by Fig. 10 and in longitudinal section in Fig. 2 this sheet metal cover being
tubular and a little larger in diameter than the diameter of the cutters so as to
surround the same and made open underneath at w¹ so as to permit of the mandrels
being successively pushed up by the rollers K' K* against the cutters as above
described. This cover W is at one end fixed to the bearing and at the other
end is fixed to a collar 6³ see Fig. 6 fixed to the end of the bearing 62. When the
cover W is required to be removed this is done by sliding the same end wise in the
direction away from the cutters a¹.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
1. In a machine for cutting up cardboard and like cylinders into short lengths
and in combination with a series of circular cutters mounted side by side on a
spindle and adapted to revolve rapidly, the employment of an intermittently
revolving chuck concentric with the said cutter spindle and carrying parallel with
the same three or more mandrels on which the cardboard cylinders are placed, a
pair of rollers parallel with the said cutter spindle and adapted to move towards
and from the same, and a stripping device adapted to embrace one of the mandrels
and to move to and fro along the same, the said parts being so arranged that whilst
the said chuck is at rest the said rollers move towards the cutters and press one of
the cardboard cylinders and its mandrel against the same so that the cylinder and
mandrel and rollers are by the cutters caused to revolve and the cardboard cylinder
is by the cutters cut up into short lengths, the rollers and mandrel and divided
cylinder then receding from the cutters, the said chuck with the mandrels then
makes another partial revolution bringing the mandrel on which is the divided
cylinder into position for the stripping device to act upon the same the said
stripping device then moves along the said mandrel and strips the divided cylinder
off the same at the same time that another cylinder with its mandrel is by the said
rollers being pressed against and divided by the revolving cutters and another mandrel
is in position to have a cardboard cylinder placed upon it, all substantially as
hereinbefore set forth.
2. In a cardboard or like cylinder cutting machine, the chuck made with radial
slots or guides in each of which is a mandrel holder each of the said mandrel
holders being furnished with a spring eye such as H by which the mandrel holder
and mandrel is held rigidly in the chuck whilst the cardboard cylinder is being
pushed on to the mandrel and whilst the divided cylinder is being stripped off the
same but which spring eye allows of the mandrel being moved up to the cutters
and revolving whilst the cardboard cylinder thereon is being cut up, substantially
as hereinbefore described.
3. In a cardboard or like cylinder cutting machine and in combination with the
revolving circular cutters and the chuck provided with the mandrels for the card-
board cylinders as set forth, the use of the pair of parallel rollers K' K2 carried by
slides operated by revolving cams such as M' M² so arranged that the cylinders on
the mandrels are by the said rollers successively moved towards the revolving
cutters and pressed against the same so as to be cut thereby and then the mandrel
is by the rollers allowed to recede from the cutters, the said roller slides being
adjustable so as to regulate the depth of cut made by the cutters, all substantially
as hereinbefore set forth.
4. In a cardboard or like cylinder cutting machine and in combination with the
revolving circular cutters and the chuck provided with the mandrels for the card-
board cylinders as set forth, the use of the stripper arranged to move along the

page_text: mandrel and strip the divided cardboard cylinder off the mandrel and to remain
stationary whilst the chuck is turning through a short space and then to return
clear of this mandrel ready to engage with the next mandrel and strip the divided
cylinder off the latter, substantially as hereinbefore set forth.
5. In a cardboard or like cylinder cutting machine and in combination with the
revolving circular cutters and the chuck provided with the mandrels for the card-
board cylinders as set forth, the use of the hooked pawl El adapted to turn the
chuck D intermittently in combination with the T slide G for bringing the
chuck D to rest and maintaining the same in position whilst the various operations
on the cardboard cylinders are being performed, substantially as herein before
described.
