I GEORGE LYNCH the younger of Mount Verdon Cork, in the County of the City
of Cork, Ireland, Manager of the Silverspring Starch Works, do hereby declare the
nature of this invention to be as follows:—
In two suitable frames preferably of the letter A formation made of timber or
metal, I place a pair of rollers, made of wood, metal, or other suitable material, the
cylindrical surfaces of which are turned up true, and the axles of which rollers work
in brass or other bearings which slide in and are capable of being adjusted in
elongated gaps in the A frames, which gaps extend through nearly the whole height
of the frames. In this way the surface of one of the rollers can be made to run or
turn truly with that of the other roller, and one roller can be made to press against
the other with any amount of pressure, that may be desired by fixing the bearings of
one of the rollers so that it cannot move away from the other roller and then moving
the bearings of the second roller towards those of the fixed roller by means of screws
acting upon them either directly or through the intervention of springs, or by
means of levers and weights acting upon them; or if so desired, screws, with or
without the intervention of springs or levers and weights, may be applied to the
axles of both rollers simultaneously.
On and around the surface of one of the rollers, are fixed by means of bolts, screws,
clips, or other suitable fastenings, blades of steel, or other suitable material, some of
which are sharp, while others are blunt, and these two classes of blades are so
arranged upon the cylinder of the roller, that if the surfaces of the two rollers were
opened out flat, and a sheet of cardboard or other suitable material placed between
them, and pressure then applied to press the surfaces of the two rollers together, the
sharp blades would cut through the cardboard, and stamp out a piece of it the exact
size and shape required for the box wanted, while the blunt blades would merely
groove or score the cardboard in lines where it is required to be bent at an angle
in order to form the sides and ends of the box.

page_text: In the other roller, which is preferably although not necessarily a hollow shell,
aro slits corresponding in arrangement with the sharp blades, and grooves corre-
sponding with the blunt blades, on the first roller, so that when the two rollers are
pressed together and caused to revolve or oscillate, the blades of the one roller fit
into the slits and grooves of the other roller, and consequently when a web or sheet
of cardboard or other material is placed between the two rollers, when they are
pressed together and caused to revolve, the sharp blades cut through the cardboard
and pass into the slits, while the blunt blades press the cardboard where they come
in contact with it, against the bottom of the grooves in the other roller, and so form
grooves or scores in it, which correspond with the pattern in which the blades are
arranged on the roller; and wherever these grooves are formed the cardboard can be
bent in straight lines without difficulty and without breaking it; or if thought
preferable, in case the cardboard or other material required for the box be thin, or
for any other reason, it may not be necessary to have the second roller provided
with grooves or slits, but merely a plain smooth surfaced roller of wood, india-rubber,
copper, or other such like material.
The blades may be arranged upon the roller in different ways according to the
requirements of the manufacturer using the machine, but the same principle of
operation is retained throughout.
1st. When a machine is required to do only a small or moderate amount of work
the rollers may be of such a diameter and length that one set of blades will cover
the entire surface of the one roller, and one set of slits and grooves the entire surface
of the other roller, and consequently only one box is cut out and grooved by each
revolution of the rollers.
2nd. The rollers may be of only sufficient diameter to allow of one set of blades, or
one set of slits and grooves being placed round their respective circumferences, but
long enough to have two, three, or more sets placed side by side along them, and if
so desired, the blades in the different belts of the one roller and the slits and grooves
into which they work in the respective belts of the other roller, may be set to cut
and groove boxes of different sizes.
3rd. When large numbers of boxes of the same size, or of different sizes, are
required to be made with one machine, the roller in which the blades are placed may be
made long, and of large diameter, and have several sets of blades around each belt of its
cylindrical surface, while the other roller containing the slits and grooves into which
the blades on the first roller work, need not, unless so desired, be of larger diameter
than will permit of one set of slits and grooves being placed around each belt of its
surface, and which slits and grooves correspond in arrangement with the blades in the
respective belts of the first cylinder against which they work. When this arrangement
is adopted, the smaller roller containing the slits and grooves, must make as many
revolutions for each revolution of the larger roller containing the blades, as there are
sets of blades in each of its belts.
The blades in all the different belts of the large or first roller may be set to cut
and groove boxes of the same size, or either blades in each belt may be set to cut
and groove boxes of a different size, so that every belt of the roller carrying the
blades, and the belt of the roller containing the slits and grooves against which it
works, will cut out and groove cardboard for boxes which will be a different size from
those cut out by the blades of any other belt. A machine constructed according to
this latter arrangement is especially well suited for works where room is limited, and
the variety in the sizes of boxes required considerable.
In all these three arrangements of blades, slits and grooves, the motion to be
communicated to the rollers is a revolving one, and the machine may be worked by
a handle turned by a man or by a belt from a pulley on a shaft working on to a fast
and a loose pulley, or other arrangement on the axle of one of the rollers; or by
gearing, the shaft or the gearing being driven by steam, water, or other source
of power.
But if preferred, either on account of its being more convenient, when making
boxes from cardboard in sheets instead of from a continuous web of cardboard, or if

page_text: so desired for any other reason, the rollers of the machine may be of large diameter,
and have as many sets of blades as are required placed side by side along the roller,
but in one segment only of its cylindrical surface, and the slits and grooves in a
corresponding segment of the other roller, and an oscillating instead of a revolving
motion, may be imparted to the rollers by means of a crank, or an eccentric, driven
or worked by hand or by power.
The web or sheet of cardboard or other material is guided and fed to the rollers
containing the blades, slits, and grooves, by guide rollers placed in front of the
machine, the guide rings of which rollers are moveable, so that cardboard or material
of different widths may be dealt with, and when required, the web or sheet may be
fed to any particular belt, or belts of the rollers, while other belts with their blades
and slits revolve or oscillate without doing work.

page_text: Supported in suitable framework A¹as already explained I arrange the pair of
rollers A B of metal or other suitable material the cylindrical surfaces of which are
turned up true and the axles of which rollers A B work in brass or other bearings
which slide in and are capable of being adjusted in elongated slides in the framing
which slides extend through nearly the whole height of the frames as from 1 to 1.
In this way the surface of one of the rollers A B can be made to run or turn truly
with that of the other roller and one roller can be made to press against the other
with any amount of pressure that may be desired by fixing the bearings of one of the
rollers so that it cannot move away from the other roller, and then moving the
bearings of the second roller towards those of the fixed roller by means of screws d
acting upon them either directly or through the intervention of springs or by means
of levers and weights acting upon them; or if so desired screws with or without the
intervention of springs or levers and weights may be applied to the axles of both
rollers simultaneously.
On and around the surface of the roller B are fixed by means of bolts, screws,
chips, or other suitable fastenings the blades of steel, 661 or these blades may be of
other suitable material, some of which b¹ are sharp, while others bare blunt and these
two classes of blades are so arranged upon the cylinder of the roller that when the
surfaces of the two rollers A B are opened out flat as in the diagram Figures 4 and 5
and a sheet of cardboard or other suitable material placed between them and pressure
then applied to press the surfaces of the two rollers A B together, the sharp blades 6¹
would cut through the cardboard and stamp out a piece of it the exact size and shape
required for the box wanted, while the blunt blades & would merely groove or score
the cardboard in lines where it is required to be bent at an angle in order to form the
sides and ends of the box.
The other roller A which is preferably although not necessarily a hollow shell is
turned up truly cylindrical and having grooves a in its surface corresponding with
the blunt blades on the first roller, so that when the two rollers A B are pressed
together and caused to revolve, or oscillate, the sharp blades of the one roller press
against the smooth surface of the other roller and cut through any material placed
between them while the blunt blades project into the grooves of the other roller
sufficiently deep to score or mark the material placed between them without cutting
through and consequently when a web, or sheet, of cardboard is placed between the
two rollers when they are pressed together and caused to revolve the sharp blades
cut through the cardboard while the blunt blades press the cardboard where they
come in contact with it against the bottom of the grooves in the other roller and so
form grooves or scores in it which correspond with the pattern in which the blades
are arranged on the roller; and wherever these grooves are formed the cardboard can
be bent in straight lines without difficulty and without breaking it or if thought
preferable in case the cardboard required for the box be thin or for any other reason
it may not be necessary to have the second roller provided with grooves or slits but
made a plain smooth surfaced roller of wood India rubber copper or other such like
material.
The blades may be arranged upon the roller in different ways according to the
requirements of the manufacturer using the machine, but the same principle of
operation is retained throughout 1st when a machine is required to do only a small
or moderate amount of work the rollers may be of such a diameter and length that
one set of blades will cover the entire surface of the one roller and one set of grooves
the entire surface of the other roller and consequently only one box is cut out and
grooved at each revolution of the rollers.
2nd The rollers may be of only sufficient diameter to allow of one set of blades or
one set of grooves being placed round their respective circumferences, but long enough
to have two, three, or more sets, placed side by side along them and if so desired the
blades in the different belts of the one roller and the grooves into which they work in
the respective belts of the other roller may be set to cut and groove boxes of different
sizes.
3 When large numbers of boxes of the same size, or of different sizes, are required

page_text: to be made with one machine the roller in which the blades are placed may be made
long and of large diameter and have several sets of blades around each belt of its
cylindrical surface while the other roller containing the grooves into which the blades
on the first roller work need not, unless so desired, be of larger diameter than will
permit of one set of grooves being placed around each belt of its surface, and which
grooves correspond in arrangement with the blades in the respective belts of the first
cylinder against which they work. When this arrangement is adopted the smaller
roller containing the grooves must make as many revolutions for each revolution of
the larger roller containing the blades, as there are sets of blades in each of its
belts.
The blades in all the different belts of the larger or first roller may be set to cut
and groove boxes of the same size, or the blades in each belt may be set to cut and
groove boxes of a different size, so that every belt of the roller carrying the blades and
the belt of the roller containing the slits and grooves against which it works will cut
out and groove, cardboard for boxes which will be a different size from those cut out
by the blades of any other belt. A machine constructed according to this latter
arrangement is especially well suited for works where room is limited and the variety
in the sizes of boxes required, considerable.
In all these three arrangements of blades and grooves the motion to be communicated
to the rollers is a revolving one and the machine' may be worked by a handle turned
by a man or by a belt from a pulley on a shaft working on to a fast and a loose
pulley or other arrangement on the axle of one of the rollers: or by gearing, the shaft
on the gearing being driven by steam, water, or other source of power.
But if preferred, either on account of its being more convenient-when making
boxes from cardboard in sheets instead of from a continuous web of cardboard, or if
so desired for any other reason, the rollers of the machine may be of large diameter
and have as many sets of blades as are required placed side by side along the rollor,
.but in one'segment only of its cylindrical surface, and the grooves in a corresponding
segment of the other roller, and an oscillating instead of a revolving motion may be
imparted to the rollers by means of a crank, or an eccentric driven or worked by
hand, or by power.
The web or sheet of cardboard is guided and fed to the rollers containing the blades,
slits and grooves, by guido rollers placed in front of the machine, the guide rings
of which rollers are moveable so that cardboard of different widths may be dealt
with and when required the web or sheet may be fed to any particular belt or
belts, of the rollers while other belts with their blades and slits revolve or oscillate
without doing work.
Having now particularly described and ascertained the nature of my said invention,
and in what manner the same is to be performed, I declare that what I claim is :-
The combination or arrangement and use in machinery for manufacturing card-
board and other boxes, of two rolls having blunt creasing blades on the one roller
pressing the material in operation into recesses in the other roller and sharp cutting
edges on the one roller acting against smooth surfaces of the other roller to cut the
material between them as and for the purpose substantially as set forth.
