Improvements in Machinery for the Production of Parts of Cardboard
Egg Boxes or the like.
I, SAMUEL CROPPER, of 30, 32, and 34, Southwark Bridge Road, in the County
of Surrey, Managing Director of a Public Company, do hereby declare the nature
of this invention, partly the result of a communication to me from abroad by
Thomas Lavender Cornell, of Derby, in the State of Connecticut, United States
of America, and partly my own invention to be as follows:-
The invention relates to improvements in machinery for the production of parts
of cardboard egg boxes or the like and has for its object primarily to produce
in a continuous and rapid manner the parts to form the internal fittings or
partitions of egg boxes.
In carrying the invention into effect a main frame is employed provided with
extensions at each end consisting of frames or platforms at their inner ends
pivotally connected with the main frame and at their outer ends furnished with
supporting feet or legs.
One of these extensions is adapted to receive a roll of cardboard which is
carried by a cylindrical bobbin mounted with capability of revolving upon centres
of motion and the outer end of this roll of cardboard is conducted under and
over guide bars and it thence passes vertically upward over and beneath other
guide bars on to the work table and to and between the feed rolls.
The passing of the cardboard around the several guide bars in reverse directions
as hereinbefore described has the effect of removing from the cardboard the curl
or twist which has become imparted thereto whilst in the roll and said guide
bars further serve to impart the necessary tension to the material and in order
to regulate said tension some of the guide bars are capable of being raised and
lowered so as to vary the angles between the same and thus regulate the tension
upon the card.
The continuous length of cardboard is carried forward by the feed rollers
which are intermittently driven by means of ratchet gearing actuated from the
main shaft of the machine and is thereby fed between vertically reciprocating
punches or cutters and stationary co-acting dies shaped to remove portions of
the cardboard and make the required slots. incisions or notches therein for the
purpose of joining the strips constituting the divisions of an egg box.
The lower dies are carried by a bar fixed transversely of the machine and
the upper punches or cutters are adjustably carried by a bar which receives a
vertical reciprocating intermittent movement in the following manner.
The bar carrying the punches is at each end thereof fixed with a crosslipad
mounted on guide-pins with capability, of vertical movement and said bar is
forced in a downward direction so as to make the required cuts or incisions in
the card by means of rods or links the unner ends of which are connected with
the crossheads and the lower ends of which are pivotally connected with levers
which are acted upon at the times desired by means of cams upon a counter shaft

page_text: hereinafter called the punch cam shaft and the cams are so timed or shaped
that after the punches have made the required cuts or incisions in the cardboard
and retired a dwell or rest occurs whilst the feed takes place.
The feed rollers receive their intermittent motion through a lever and ratchet
mechanism from a cam upon the punch cam shaft and this motion is so regulated
that during the downward stroke of the punches or cutters the length of card
will remain stationary.
After having been acted upon by the punches or cutters the length of card-
board is carried between a number of rotary cutters consisting of steel discs with
flat peripheries and sharp edges mounted upon shafts located transversely of
the machine and which shafts are coupled by suitable gearing and receive motion
through a band wheel or pulley so that said shafts receive a continuous rotary
motion and in the passage therethrough of the length of card longitudinally
divide the same into strips of the required width.
The strips of card thence pass between shears arranged transversely of the
machine and carried in a laterally adjustable frame and the upper one of the
shear blades is fixed whilst the lower one is forced upward to give the required
cut by means of levers actuated by cams upon a counter shaft hereinafter called
the shears cam shaft in such manner that the shears act at the moment of the
dwell or rest in the feeding forward of the sheet of card.
The lengths of card as they are severed from the strips are received between
endless bands of tape or the like alternately of different lengths which are
mounted upon spindles geared together and continuously driven at a high rate
of speed through a separate pulley and as the lengths of card are carried forward
by these endless tape carriers they are received into a box provided for that
purpose formed with two rows of compartments the compartments of one row
being arranged in different vertical planes from those of the other row and this
box is mounted with capability of removal upon one of the extensions of the
frame.
By this peculiar arrangement of the tape carriers and compartments of the
box or receiver the short bands will deliver the lengths of card into one set of
compartments and the long bands into the other set.
In the absence of this device it would be difficult or impossible to deliver the
lengths of card into separate compartments by reason of said lengths although
divided being virtually in contact at their side edges.
In order to vary within certain limits the speed of the shears and consequently
the size of the lengths of card cut off the strips according to the dimensions
required to be given to the finished lengths of card, motion is transmitted from
the punch cam shaft of the machine to the shears cam shaft through a train of
toothed gearing which gears with a change wheel removably fixed upon the
shears cam shaft and said train is mounted upon a radius arm or carrier adapted
to be moved over a slotted segment and fixed in any desired position by means
of a nut and bolt so that change wheels of different diameters may be mounted
upon the shears cam shaft according to the speed desired to be given to the
shears and the radius arm or carrier for the train of wheels may be adjusted in
position according to the diameter of the change wheel for the time being
employed.
In some cases it is desirable to leave blank ends beyond the end notches of
the finished lengths of card for the purpose of forming protecting buffers between
the egg box and the partitions and in order to effect this object a rod is at one
end connected with the pawl or driver of the ratchet feed mechanism and at
the other end connected with a spring and the spring end of this rod which is
normally held by a hook out of the way is provided with a stud or offset which
at the times desired is by releasing the rod from the hook brought into the path
of a stud upon the face of a disc or wheel fixed with the shears cam shaft.
By this device the ratchet driver of the feed will be periodically tripped with
the result that the motion of the feed rollers will be reduced and the cut of the

page_text: shears will be made in the required position between the notches or incisions
to leave the buffer ends to the strips of card and in conjunction with this device
the position of the cut is also regulated by the lateral adjustment of the shears.
By the means herein before described a machine is obtained which is practically
automatic in its action and requires no attention after having been first set to
produce the required strips of card the only attention necessary being to remove
the box or receiver for the finished lengths and to substitute a new one and to
renew the roll of card when exhausted.

Improvements in Machinery for the Production of Parts of Cardboard
Egg Boxes or the like.
I, SAMUEL CROPPER, of 30, 32, and 34, Southwark Bridge Road, in the County
of Surrey, Managing Director of a Public Company, do hereby declare the nature
of this invention, partly the result of a communication to me from abroad by
Thomas Lavender Cornell, of Derby, in the State of Connecticut, United States
of America, and partly my own invention, and in what manner the same is to
be performed to be particularly described and ascertained in and by the following
statement:-
:-
The invention relates to improvements in machinery for the production of parts
of cardboard egg boxes or the like and has for its object primarily to produce
in a continuous and rapid manner the parts to form the internal fittings or
partitions of egg boxes.
In carrying the invention into effect a main frame is employed provided with
extensions at each end consisting of frames or platforms at their inner ends
pivotally connected with the main frame and at their outer ends furnished with
supporting feet or legs.
One of these extensions is adapted to receive a roll of cardboard which is
carried by a cylindrical centre or bobbin mounted with capability of revolving
upon centres of motion and the outer end of this roll of cardboard is conducted
under and over guide bars and it thence passes vertically upward over and beneath
other guide bars on to the work table, and to and between the feed rolls.
The passing of the cardboard around the several guide bars in reverse directions
as hereinbefore described has the effect of removing from the cardboard the curl
or twist which has become imparted thereto whilst in the roll and said guide
bars further serve to impart the necessary tension to the material and in order
to regulate said tension some of the guide bars are capable of being raised and
lowered so as to vary the angles between the same and thus regulate the tension
upon the card.
The continuous length of cardboard is carried forward by the feed rollers
which are intermittently driven by means of ratchet gearing actuated from the
main shaft of the machine and is thereby fed between vertically reciprocating
punches or cutters and stationary co-acting dies shaped to remove portions of
the cardboard and make the required slots incisions or notches therein for the
purpose of joining the strips constituting the divisions of an egg box.
The lower dies are carried by a bar fixed transversely of the machine and

page_text: the upper punches or cutters are adjustably carried by a bar which receives a
vertical reciprocating intermittent movement in the following manner.
The bar carrying the punches is at each end thereof fixed with a crosshead
mounted on guide pins with capability of vertical movement and said bar is
forced in a downward direction so as to make the required cuts or incisions in
the card by means of rods or links the upper ends of which are connected with
the crossheads and the lower ends of which are pivotally connected with levers
which are acted upon at the times desired by means of cams upon a counter shaft
hereinafter called the punch cam shaft and the cams are so timed or shaped
that after the punches have made the required cuts or incisions in the cardboard
and retired a dwell or rest occurs whilst the feed takes place.
The feed rollers receive their intermittent motion through a lever and ratchet
mechanism from a cam upon the punch cam shaft and this motion is so regulated
that during the downward stroke of the punches or cutters the length of card
will remain stationary.
After having been acted upon by the punches or cutters the length of card-
board is carried between a number of rotary cutters consisting of steel dises with
flat or bevel peripheries and sharp edges mounted upon shafts located transversely
of the machine and which shafts are coupled by suitable gearing and receive motion
through a band wheel or pulley so that said shafts receive a continuous rotary
motion and in the passage therethrough of the length of card longitudinally
divide the same into strips of the required width.
The strips of card thence pass between shears arranged transversely of the
machine and carried in a laterally adjustable frame and the upper one of the
shear blades is fixed whilst the lower one is forced upward to give the required
cut by means of levers actuated by cams upon a counter shaft hereinafter called
the shcars cam shaft in such manner that the shears act at the moment of the
dwell or rest in the feeding forward of the sheet of card.
The lengths of card as they are severed from the strips are received between
endless bands of tape or the like alternately of different lengths which are
mounted upon spindles geared together and continuously driven at a high rate
of speed through a separate pulley, and as the lengths of card are carried forward
by these endless tape carriers they are received into a box provided for that
purpose formed with two rows of compartments the compartments of one row
being arranged in a different vertical plane from those of the other row and this
box is mounted with capability of removal upon one of the extensions of the
frame.
By this peculiar arrangement of the tape carriers and compartments of the
box or receiver the short bands will deliver the lengths of card into one set of
compartments and the long bands into the other set.
In the absence of this device it would be difficult or impossible to deliver the
lengths of card into separate compartments by reason of said lengths although
divided being virtually in contact at their side edges.
In order to vary within certain limits the speed of the shears and consequently
the size of the lengths of card cut off the strips according to the dimensions
required to be given to the finished lengths of card motion is transmitted from
the punch cam shaft of the machine to the shears cam shaft actuating the shears
through a train of toothed gearing which gears with a change wheel removably
fixed upon the shears cam shaft and said train is mounted upon a radius arm
or carrier adapted to be moved over a slotted segment and fixed in any desired
position by means of a nut and bolt so that change wheels of different diameters
may be mounted upon the shears cam shaft according to the speed desired to be
given to the shears and the radius arm or carrier for the train of wheels may be
adjusted in position according to the diameter of the change wheel for the time
being employed.
In some cases it is desirable to leave blank ends beyond the end notches of
the finished lengths of card for the purpose of forming protecting buffers between

page_text: the egg box and the partitions and in order to effect this object a rod is at one
end caused to act upon the pawl or driver of the ratchet feed mechanism and at
the other end connected with a spring and the spring end of this rod which is
normally held by a hook out of the way is provided with a stud or offset which
at the times desired is by releasing the rod from the hook brought into the path
of a stud upon the face of a disc or wheel fixed with the shears cam shaft.
By this device the ratchet driver of the feed will be periodically tripped with
the result that the motion of the feed rollers will momentarily cease and the cut
of the shears will be made in the required position between two notches or
incisions to leave the buffer ends to the strips of card and in conjunction with
this device the position of the cut is also regulated by the lateral adjustment
of the shears.
And in order that the said invention may be more clearly understood and
readily carried into effect I will proceed aided by the accompanying drawings
more fully to describe the same.

Figures 17 and 18 are drawn to a still further increased scale.
a represents the main frame of the machine which is at each end thereof
provided with extensions consisting of frames or platforms a¹ at their inner
ends pivotally connected with the main frame w by means of transverse rods or
shafts and at their outer ends furnished with supporting feet or legs a³.
One of these extensions is adapted to receive a roll of cardboard & which is
carried by a cylindrical centre or bobbin & mounted with capability of revolving
upon V centres c formed upon the ends of threaded spindles c screwing through
the frames and provided with hand wheels to facilitate adjustment and to
provide an easy means of dismounting the bobbin ¿¹ to admit of the introduction
of a fresh roll of card b at the times desired.
The free end of the roll of cardboard is conducted between guide plates d
under and over guide bars d¹ d² and then passes vertically upward over and

page_text: beneath other guide bars d' onto the work table at and to and between the
feed rolls c e¹.
The passing of the cardboard around the several guide bars d² №¾³ d¹ in
reverse directions as herein before described and as shown at Figures 1 and 3
has the effect of more or less removing from the cardboard the curl or twist
which has become imparted thereto whilst in the roll and said guide bars further
serve to impart the necessary tension to the card band in order to regulate said
tension the guide bar is at its ends mounted with capability of adjustment
in slots provided in the sides of the frame a whilst the guide bar a is
formed with reduced ends to fit into holes a provided in guide plates or cheeks a
carried by the table by which means the guide bars may be raised and lowered
so as to vary the angles between the same and thus regulate the tension on the
length of card b.
The continuous length of cardboard is carried forward by the feed rollers e e¹
which are geared together by toothed wheels 2 and are intermittently driven
by means of ratchet gearing consisting of a ratchet wheel fixed upon the
axis of the roller e and a co-acting pawl or driver held to its work by a
spring and which pawl e is pivotally carried by an arm or lever loosely
mounted upon the prolonged journal or axis e* of the feed roller e and held in
position by means of a collar fixed with said journal.
The arm or lever is pivotally connected to the upper end of a link the
lower end of which is pivotally connected to a levere which is loosely mounted
upon the fixed shaft or axis and this lever e is acted upon by means of a
cam ffixed upon the punch cam shaft f hereinafter more fully referred to,
and which has fixed thereon a chain wheel f by means of a chain geared
with a corresponding chain wheel g² fixed upon the main shaft g of the machine
which is provided with fast and loose pulleys gl receiving motion by a band gl*
from any suitable source of power.
The main shaft
is thus continuously driven whilst the feed rolls e e¹ through
the cam f¹ lever e pawl or driver e and ratchet wheel & receive an intermittent
or step by step rotary motion and the length of card is thereby fed between
vertically reciprocating punches or cutters and stationary co-acting dies i
shaped to remove portions of the cardboard and make the required slots incisions
or notches therein for the purpose of joining the strips constituting the
divisions of an egg box as shown more particularly at Figures 15 and 17, but
it will be understood that the shape of the punches and dies may be varied
according to the nature of the cut or incision required to be produced.
The lower dies are carried by or formed in a bar or die plate i arranged
transversely of the machine and countersunk in the bed plate or table at and
the upper punches or cutters are adjustably carried by a bar which receives
a vertical reciprocating intermittent movement in the following manner.
The bar carrying the punches his at each end thereof fixed with a cross-
head mounted with capability of vertical movement on guide pins 2* fixed
with the bed plate or table and said bar h is forced in a downward direction
so as to make the required cuts or incisions in the card by means of rods or
links the upper ends of which are threaded and pass through vertical holes
formed in the crossheads 2 and are fixed therewith by means of nuts * screwing
upon the rods h³.
The rods are fixed with slide blocks which work in vertical slots or
guides formed in part of the frame a and the slide blocks are pivotally
connected by short links * with levers which at one end are loosely mounted
upon the fixed shaft and at the opposite end are acted upon at the times
desired by means of cams f³ fixed upon the punch cam shaft f and the cams f
are so timed or shaped that after the punches have made the required cuts
or incisions in the cardboard and retired a dwell or rest occurs whilst the feed
takes place.
The feed rollers e e¹ receive their intermittent motion through the cam f¹

page_text: lever and ratchet mechanism ee hereinbefore described and this motion is
so regulated that during the downward stroke of the punches or cutters the
length of card b will remain stationary.
Guide bars h* are provided adjacent to the punches h₁ and beneath which the
length of card passes and which serve to hold the card during the withdrawal
of the punchies.
After having been acted upon by the punches or cutters ¹ the length of card-
board is carried between a number of suitably spaced rotary cutters g³ g
consisting of steel discs with bevelled peripheries and sharp edges, one set g³
being fixed upon the main shaft g and the other g upon a shaft mounted
with capability of adjustment towards the shaft g and which shafts are geared
together so as to work in unison by means of toothed wheels and receive
motion through the band wheel or pulley g¹ so that the shafts g g* and cutters
gg have imparted thereto a continuous rotary motion and in the passage between
said cutters of the length of card the same is longitudinally divided into
strips of the required width.
The sheet of card 6 is now divided longitudinally into strips and these strips
pass between shear blades 7 m arranged transversely of the machine and the
upper one of these shear blades is fixed by means of screws with a bar
or frame mounted upon the table at of the machine and adjustably fixed
therewith by means of vertical bolts or studs 7* passing through slots 73 in the
flanges of the frame or bar 72 and screwing into tapped holes in the table at so
that the entire frame or bar 72 together with the knives or cutters 1 is capable
of lateral adjustment.
The lower one m of the shear blades is vertically slotted and adjustably fixed
with a crossbar m³ by means of threaded studs m¹ passing through slots m²
therein a set screw m impinging upon the screw m being employed to prevent
the accidental slacking back of the parts.
The crossbar m³ is at its ends provided with bosses or enlargements m³ which
are nerforated and work upon studs or spindles m** fixed with the underside
of the table a and the crossbar m³ is forced upward to give the required cut
to the strips of card by means of levers me at one end pivotally connected
by links m✶ to the crossbar m³ and at the other end loosely mounted upon the
fixed shaft and these shears levers m are provided with trucks or rollers m
mounted upon studs projecting laterally therefrom and these trucks or rollers
are acted upon by cams n¹ fixed upon a transverse shaft n hereinafter called the
shears cam shaft mounted with capability of revolution in bearings provided
in the frame of the machine in such manner that the shears 1 m act at the
moment of the dwell or rest of the feeding forward of the sheet of card b.
In order to keep under control the extreme ends of the strips of card and also
the lengths after the cut by the shears 1 m guide strips or bars 7** or they
might be rollers are provided at both sides of the shear blade 7 under which
said strips and lengths are caused to pass.
The lengths of card 6* as they are severed from the strips are received between
endless bands of tape or other suitable material oot of those which are shorter
than the others being arranged alternately with those o¹ for the purpose herein-
after described and these endless bands are mounted upon shafts or spindles o* o!*
02 and the adjacent spindles o* 2* are coupled by means of toothed gearing o³
so that the bands will all be driven at an equal rate of speed whilst motion is
transmitted from the engine to the shaft or spindle through a band and
band wheel or pulley of fixed upon the end of the shaft 02*
In order to provide for the adjustment of the endless hands oo o² the shafts
or spindles ool* 2* are mounted in bearings carried by travellers of *
mounted upon fixed rods of carried in standards as from the table and the
travellers of are adapted to be adjusted by means of regulating screws of which
are mounted with capability of turning freely in the standards as and at their
ends are threaded to engage nuts formed in downward projections from the

page_text: travellers of whilst the traveller o* is adjusted by hand and fixed in the required
position by means of set screws o** impinging upon the rods o
The endless bands o o¹ 02 are at their inner ends guided in their movements
or held in the same relative position by means of trough shaped guides o
carried by rods 10 fixed with the frame of the machine the guides of the
bands o
being arranged above the same, whilst those of the bands o' 02 are
inverted and placed below the same.
The bands ooo are continuously driven at a high rate of speed which may
be regulated as desired by reason of the pulley being independently driven
and as the lengths of card are carried forward by these endless tape carriers
or bands they are received into a box ? provided for that purpose and formed
with two rows of compartments the compartments pi of one row being
arranged in a different vertical plane from those 22 of the other row and this
box P
is mounted with capability of removal upon one of the extensions al of
the frame a.
By this peculiar arrangement of the tape carriers o o¹ 02 and compartments p¹ p²
of the box or receiver the short bands o in conjunction with the upper
bands will deliver the lengths of card into one set of compartments namely
those 2 and the longer hands o¹ in conjunction with those o will deliver the
lengths of card into the other set of compartments p¹.
In the absence of this device it would be difficult or impossible to deliver the
lengths of card into separate compartments by reason of said cards although
divided being virtually in contact at their side edges and not separated sufficiently
to admit of their passing the partitions of the compartments.
In order to vary within certain limits the speed of the shears and consequently
the size of the lengths 6* of card cut off the strips according to the dimensions
required to be given to the finished lengths of card, motion is transmitted from
the punch cam shaft f of the machine to the shears cam shaft n through a train
of toothed gearing consisting of a toothed pinion q¹ fixed upon the punch cam
shaft which gears with a toothed wheel q2 fixed with a toothed pinion g3 which
gears with another pinion 7 which engages a change wheel remov-
ably fixed upon the shears
shaft
cabi
train with
and said
22
exception of gland is mounted upon studs fixed with the
radius arm or carrier 77 adapted to be moved over the arc of a circle at one
end loosely mounted upon the punch cam shaft f and at the other end provided
with a slotted quadrant which receives a bolt * fixed with the frame a of
the machine by tightening the nut of which the radius arm may be fixed in
any desired position.
the
By this arrangement of parts change wheels q of different diameters may
be mounted upon the shears cam shaft n according to the speed desired to be
given to the shears 7 m and which governs the length of the cardboard strip
and the radius arm or carrier g for the train of wheels may be adjusted in
position according to the diameter of the change wheel for the time being
employed.
In some cases it is desirable to leave blank ends beyond the end notches 72
of the finished lengths of card * for the purpose of forming protecting buffers b*t
as shown at Figure 16 between the egg box and the divisions or compartments
in which the eggs are stored instead of forming compartments right up to the
sides of the box and in order to effect this object a rod is at one end pivotally
connected with an offset from a notched disc e loosely mounted upon the exten-
sion of the shaft of the feed roller e and the shoulder * of this disc e in
the position indicated by the dotted lines in Figure 5 and by the full lines in
Figure 7 is adapted to engage an offset *** from the pawl or driver et of the
ratchet feed mechanism.
The rod at the other end is connected with a spring " and the spring
end of this rod which is normally held out of the way by means of a hook *
depending from the work table a is provided with a stud, projection, notch,

page_text: or offset eo which at the times desired is by releasing the rod e from the
hook brought into the path of a stud r projecting from the face of a disc
or wheel r fixed with the shears cam shaft n.
By this device the pawl or ratchet driver e of the feed which usually engages
alternate teeth of the ratchet wheel e will be periodically tripped and caused
to miss one tooth of said wheel with the result that the motion of the feed
rollers e e will shortly after the punch h¹ has made an incision momentarily
cease at the time when the strip is to be divided by the shears m and this will
permit the punch to make two incisions near together as shown at the
left hand of Figure 16 and the cut of the shears m will be made in the required
position between said notches or incisions so as to leave the buffer, ends 6*1
to the strips of card 6* and in conjunction with this device the position or timing
of the cut must also be regulated by the lateral adjustment of the shears and by
the size and adjustment of the change wheel q through which the shears cam
shaft n is driven.
By the means hereinbefore described a machine is obtained which is practically
automatic in its action and requires no attention after having been first set to
produce the required strips of card it being only necessary to remove the box
or receiver p filled with finished lengths and to empty the same or to substitute
a new box and also to renew the roll of card b when exhausted.
It will be understood that although the machine is especially intended for
the production of the partitions or internal fittings of egg boxes it is equally
applicable to the production of strips or lengths for other purposes.
