of Middlesex, Engineer and Patent Agent, for the Invention of "IM-
PROVEMENTS IN APPARATUS FOR CUTTING PASTEBOARD AND OTHER LIKE
BOARDS." A communication from abroad by Elizier Ely Clarke, of the
City and County of New Haven, State of Connecticut, in the United
States of America.
PROVISIONAL SPECIFICATION left by the said William Clark at the
Office of the Commissioners of Patents, with his Petition, on the 21st
March 1865.
I, WILLIAM CLARK, of 53, Chancery Lane, in the County of Middlesex,
Engineer and Patent Agent, do hereby declare the nature of the said
Invention for "IMPROVEMENTS IN APPARATUS FOR CUTTING PASTEBOARD AND
OTHER LIKE BOARDS," to be as follows:-
The first part of the present Invention relates to certain new and useful
improvements in the mode of attaching the cutter holders and stocks to the
cutter beam of pasteboard cutting machines, and consists, first, in forming
in the upper surface of the cutter beam, extending across the machine and
made secure to the framework of the same, a horizontal groove of a square

page_text: shape, and in the lower surface of the beam, along its outer edge, a hori-
zontal angular shaped groove, both extending the entire length of the beam.
On the beam the cutter stock is placed, resting by a right angular arm upon
the upper surface of the beam, and extending downward along the side
thereof, having at its lower end another projecting arm, made on its inner
surface, of corresponding shape to the angular groove before referred to, and
fitting within the same. Through the upper arm of the stock a vertical
set screw is passed, having its seat in a shoe placed within the horizontal
groove of the surface of the beam, upon which said arm rests. By turning
the screw down the stock can be made tight on its beam, and by turning
it up it can be easily moved to any desired position upon the beam, and
there set as above. The lower outer portion of cutter stock is made
inclined towards the centre of the top of the cutter roller, and has a
dovetail guide formed thereon, on which sets a straight cutter holder having
a corresponding shaped groove on its surface in contact therewith, so as to
be freely moved thereon. In a slot of the lower end of cutter holder the
cutter is placed, turning on suitable bearings therein. On the upper end of
cutter holder a screw rod is attached; which passes upwards through a pro-
jecting arm of the cutter stock, and has on the same two nuts, one above and
the other below the said arm, by the turning of either of which, and bringing
it to a bearing against the said arm, the cutter holder is either raised or
lowered, as the case may be, and thus the cutter adjusted to any position
with regard to the cutter roller, according as it may be desired to cut the
pasteboard entirely through or simply to "score" it; by bringing both nuts to
a bearing on the arm of cutter stock the cutter is set and firmly held to the
stock. Secondly, in forming the cutter stock of a straight bar having at each of
its ends projecting arms, which fit and bear upon the upper and lower surfaces
of the cutter beam. In the side surface of cutter beam is a horizontal
T-shaped groove extending its entire length, and in the cross bar of which is
inserted the head of a screw rod passing outward through its tail portion and
the entire thickness of cutter stock, as well also as the thickness of the cutter
holder placed upon the outside of the stock, and having a nut upon it's outer
end. By screwing the nut up hard upon the cutter holder it and the
stock are firmly held against the cutter beam, and by unscrewing the nut the
stock and bar can be moved along upon the beam, and set at any desired
position thereon. The cutter holder has its lower end bent in and under the
cutter beam, and has a cutter placed therein as before described. Attached
to the top of the cutter holder is a vertical screw rod, which passes upward
through a projecting arm of the cutter stock, and on which two nuts are

page_text: placed, arranged and operating as herein-before described for the straight
cutter holder. Another way of moving the cutter holder in a vertical plane
or rather of adjusting its cutter near to or far from the cutter holder, is to
pass, its screw rod up through a grooved nut placed in a slot of the projecting
arm of the cutter stock, whereby by turning the nut either to the right or
left I accordingly raise or lower the cutter holder. Thirdly, in dispensing with
the cutter stock and fastening the cutter holder directly to the cutter beam"
which I do by forming in the side surface of the beam two horizontal parallel
grooves, one of which is made in the shape of a T, and the other square, in the
cross portion of the former of which fits the head of a screw rod, passing outward
therefrom, and through a vertical slot of the cutter holder, having a screw nut
on its outer end, and in the other of which the tail of a T-shaped piece fits,
the cross portion of which fits within a vertical groove in rear surface of cutter
holder, thus keeping the holder perpendicular on its cutter beam. Fourthly,
in raising and lowering the cutter holder, arranged as just above described,
by forming and attaching to the upper end of said holder a vertical screw rol,
which rod has on its upper end a grooved nut, placed in a forked-shaped piecè
projecting from the beam, and held by a dovetail groove in the same, by tho
screwing of which nut to the right or left the desired result is obtained, and
moreover the cutter holder cau be moved along to any position on the cutter
beam. In lieu, however, of having the forked shaped piece in which the
screw nut is placed, I can form a suitable shaped groove for the nut in the
beam or a projecting arm of the beam.
The second part of the Invention relates to new modes of adjusting tho
cutters for the cutting of pasteboard to different widths, and consists,
first, in the use of a suitable graduated scale or measure supported in proper
guides upon each side or standards of the machine, and placed so that the
graduated edge can be brought close to the cutting edge of the cutter;
second, in the use of a graduated scale or rule placed upon the top or side
surface of the cutter beam, together with suitable shaped index hands or
pointers fastened to the stocks or holders of the cutter, as the case may be.
The third part of the Invention relates to the mode of arranging or adjusting
the position of the feed rollers of the machine with regard to each other, which
consists in suspending the boxes which support the bearings of the upper roll
on screw rods, the heads of which rest upon the top of the standards of the
machine, whereby by turning the screws into the boxes the roll will be raised,
and by the reverse lowered, thus enabling me to perfectly adjust the upper
roll in any parallel position with regard to the lower roll, and hold the same
firmly therein.

page_text: The fourth part consists in the use of a zig-zag shaped cutter or cutters for
the cutting of zig-zag edges, which are necessary to be given to the ends of a
pasteboard box made in the shape of a cylinder, so as to turn the same under
the bottom; also in the use of a serpentine shaped cutter or other desired
shapes, according to the cut to be given to the pasteboard.
The fifth part relates to certain new and useful improvements in machines
for the cutting of pasteboards, by which both the scoring and through cut may
be effected at one operation, and also so constructing combining the parts
of the machine that the same may be worked in a great measure automatically
with great accuracy, expeditiousness, and efficiency, and consists, 1st, in
the use of fixed cutters and a revolving cutting cylinder susceptible of adjust-
ment with regard to the same by being raised to or lowered therefrom, in order
that the cutter may more or less indent or cut the pasteboard, as may be desired.
2ndly, in combining in one machine with two or more cutters, holders
provided with adjustable or fixed cutters, two cylinders geared so as to
revolve velocities, one of the said cylinders revolving in fixed bearings,
while the other, actuated by any suitable mechanism, can be raised to or
lowered from the cutters at pleasure. 3rdly, in combining with stationary or
adjustable cutters, and revolving cutter cylinder a cam cylinder or wheels revolving
in unison with the cutter cylinder and actuating it to more or less impinge
against the cutters at given intervals of space. 4thly, in combining with the
cutters, cutter cylinder, and cam wheel a feed bar, actuated by the cam or
any part moving in unison therewith, in such manner as to feed the sheet to the
cutters automatically and at proper intervals of time during the revolution of
the eam wheel to receive the through and score cuts between given points.
5thly, in arranging the cam piece upon the wheel in such a manner as to
be easily adjusted to any desired positions therein, or to be detached therefrom
at pleasure, which is accomplished by forming upon one end edge of the
periphery of the wheel, and extending entirely around the same, a raised lip
or projecting rim, and in the opposite surface of the wheel a T-shaped groove
extending around the wheel parallel to its periphery, in which groove corre-
sponding shaped bolt heads are placed, the bolts of which pass outward from
the same through a proper shaped clamp, between the upper end of which and
the raised lip of wheel the cam pieces are inserted, and held by screwing the
nut of said bolt firmly up against the clamp. The clamps can be set at any
desired position on the wheel, and can be removed therefrom at pleasure.
6thly, arranging the platform on which the board as fast as it is cut is received
in any proper manner to permit it to be moved under the main cylinder, so
that the cutters can be easily reached, and thus readily adjusted when desired.

page_text: 7thly, in the use of a horizontal feed bar moving in suitable guiding grooves
of the platform, from which the pasteboard is fed to the cutters, which feed
bar is actuated through suitable devices connected with the driving power of
the machine in proper manner to push and slide the pasteboard to the cutter
at the desired time.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said William Clark in the Great Seal Patent Office on the 20th
September 1865.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
CLARK, of 53, Chancery Lane, in the County of Middlesex, Engineer and
Patent Agent, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters.
Patent, bearing date the Twenty-first day of March, in the year of our Lord
One thousand eight hundred and sixty-five, in the twenty-eighth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said William Clark, Her special licence that I, the said William Clark, my
executors, administrators, and assigns, or such others as I, the said William
Clark, my executors, administrators, and assigns, should at any time agree
with, and no others, from time to time and at all times thereafter during
the term therein expressed, should and lawfully might make, use, exercise,
and vend, within the United Kingdom of Great Britain and Ireland, the
Channel Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN
APPARATUS FOR CUTTING PASTEBOARD AND OTHER LIKE BOARDS," a communication
to me from abroad by Elizier Ely Clarke, of the City and County of New
Haven, State of Connecticut, in the United States of America, upon the con-
dition (amongst others) that I, the said William Clarke, my executors or
administrators, by an instrument in writing under my, or their, or one of their
hands and seals, should particularly describe and ascertain the nature
of the said Invention, and in what manner the same was to be performed,
and cause the same to be filed in the Great Seal Patent Office within
six calendar months next and immediately after the date of the said Letters
Patent.
NOW KNOW YE, that I, the said William Clark, do hereby declare
the nature of the said Invention, and in what manner the same is to
be performed, to be particularly described and ascertained in and by the
following statement, reference being had to the five Sheets of Drawings

page_text: hereunto annexed, and to the letters and figures marked thereon (that is to
say):
:-
The first part of the present Invention relates to certain new and useful
improvements in the mode of attaching the cutter holders and stocks to the
cutter beam of pasteboard cutting machines, and consist, first, in forming in
the upper surface of the cutter beam extending across the machine and
made secure to the framework of the same, a horizontal groove of a
square shape, and in the lower surface of the beam, along its outer edge, a
horizontal angular shaped groove both extending the entire length of the beam.
On the beam the cutter stock is placed, resting by a right angular arm
upon the upper surface of the beam, and extending downward along the side
thereof, having at its lower end another projecting arm, made on its inner
'surface, of corresponding shape to the angular groove before referred to, and
fitting within the same. Through the upper arm of stock a vertical set screw
is passed, having its seat in a shoe placed within the horizontal groove of the
surface of the beam upon which said arm rests. By turning the screw down
the stock can be made tight on its beam, and by turning it up it can be
easily moved to any desired position upon the beam, and there set as above.
The lower outer portion of cutter stock is made inclined towards the centre of
the top of the cutter roller, and has a dovetail guide formed thereon, on which
sets a straight cutter holder having a corresponding shaped groove on its
surface in contact therewith, so as to be freely moved thereon. In a slot of the
lower end of the cutter holder the cutter is placed, turning on suitable bearings
therein. On the upper end of cutter holder a screw rod is attached, which passes
upwards through a projecting arm of the cutter stock, and has on the same
two nuts, one above and the other below the said arm by the turning of either
of which and bringing it to a bearing against the said arm the cutter holder is
either raised or lowered, as the case may be, and thus the cutter adjusted to any
position with regard to the 'cutter roller, according as it may be desired to cut
the pasteboard entirely through or simply to "score" it, by bringing both nuts
to a bearing on the arm of either stock the cutter is set and firmly held to
the stock. Second, in forming the cutter stock of a straight bar having at
each of its ends projecting arms which fit and bear upon the upper and lower
surfaces of the cutter beam. In side surface of cutter beam is a horizontal
T-shaped groove extending its entire length, and in the cross bar of which is
inserted the head of a screw rod passing outward through its tail portion and
the entire thicknes of cutter stock, as well also as the thickness of the cutter
holder placed upon the outside of the stock, and having a nut upon its outer
end. By screwing the nut up hard upon the cutter holder it and the stock

page_text: are firmly held against the cutter beam, and by unscrewing the nut the stock
and bar can be moved along upon the beam and set at any desired position
thereon. The cutter holder has its lower end bent in and under the cutter
beam, and has a cutter placed therein, as before described. Attached to
the top of the cutter holder is a vertical screw rod, which passes upwards
through a projecting arm of the cutter stock, and on which two nuts are placed
arranged and operating as herein-before described for the straight cutter
holder. Another way of moving the cutter holder in a vertical plane, or rather
of adjusting its cutter near to or far from the cutter roller, is to pass its screw
rod up through a grooved nut placed in a slot of the projecting arm of the
cutter stock, whereby by turning the nut either to the right or left, I according
raise or lower the cutter holder. Third, in dispensing with the cutter stock
and fastening the cutter holder directly to the cutter beam, which I do by
forming in the side surface of the beam two horizontal parallel grooves, one of
which is made in the shape of a T and the other square, in the cross portion of
the former of which fits the head of a screw rod passing outwards therefrom and
through a vertical slot of the cutter holder, having a screw nut on its outer
end, and in the other of which the tail of a T-shaped piece fits, the cross
portion of which fits within a vertical groove in rear surface of cutter
holder, thus keeping the bolder perpendicular on its cutter beam.
Fourth, in raising and lowering the cutter holder, arranged as just above
described, by forming and attaching to the upper end of said holder a vertical
screw rod, which rod has on its upper end a grooved nut placed in a forked
shape piece projecting from the beam, and held by a dovetail groove in the
same, by the screwing of which nut to the right or left the desired result is
obtained, and moreover the cutter holder can be moved along to any position
on the cutter beam. In lieu, however, of having the forked shaped piece, I
can form a suitable shaped groove for the nut in the beam or a projecting
arm of the beam.
The second part relates to new modes of adjusting the cutters for the
cutting of pasteboard to different widths, and consists, first, in the use of a
suitable graduated scale or measure supported in proper guides upon each side
or standards of the machine, and placed so that their graduated edge can
be brought close to the cutting edge of the cutter; second, in the use of a
graduated scale or rule placed upon the top or side surfaces of the cutter beam,
together with suitable shaped index hands or pointers fastened to the stocks
or holders of the cutter, as the case may be.
The third part of the Invention relates to the mode of arranging or adjusting
the position of the feed rollers of the machine with regard to each other,

page_text: which consists in suspending the boxes which support the bearings of the
upper roll or screw rods, the heads of which rest upon the top of the standards
of the machine, whereby by turning the screws into the boxes the roll will be
raised, and by the reverse lowered, thus enabling me to perfectly adjust the
upper roll in any parallel position with regard to the lower roll, and hold the
same firmly therein.
The fourth part consists in the use of a zig-zag shaped cutter or cutters for
the cutting of zig-zag edges, which are necessary to be given to the ends of
a pasteboard box made in the shape of a cylinder, so as to turn the same
under the bottom; also in the use of a serpentine shaped cutter or other
desired shapes, according to the cut to be given to the pasteboard.
The fifth part relates to certain new and useful improvements in machines
for the cutting of pasteboards, by which both the scoring and through cut
may be effected at one operation; and also so constructing and combining
the parts of the machine that the same may be worked in a great measure
automatically with great accuracy, expeditiousness, and efficiency, and consists
in the use of fixed cutters and a revolving cutting cylinder susceptible
of adjustment with regard to the same by being raised to or lowered
therefrom, in order that the cutter may more or less indent or cut the
pasteboard, as may be desired. Second, in combining in one machine with two
or more cutters bars provided with adjustable or fixed cutters two cylinders
geared so as to revolve with equal velocities, one of the said cylinders revolving
in fixed bearings, while the other, actuated by any suitable mechanism,
can be raised to or lowered from the cutters at pleasure. Third, in combining
with stationary or adjustable cutters and revolving cutter cylinder a cam
cylinder, or wheels revolving in unison with the cutter cylinder, and actuating
it to more or less impinge against the cutters at given intervals of space.
Fourth, in combining with the cutters, cutter cylinder, and cam wheel a feed
bar actuated by the cam wheel, or any part moving in unison therewith in
such a manner as to feed the sheet to the cutters automatically, and at proper
intervals of time during the revolution of the cam wheel to receive the
through score cuts between given points. Fifth, in arranging the cam pieces
upon the wheel in such a manner as to be easily adjusted to any desired
positions therein or be detached therefrom at pleasure, which is accomplished
by forming upon one end edge of the periphery of the wheel, and extending
entirely around the same, a raised lip or projecting rim, and in the opposite
surface of the wheel a T-shaped groove extending around the wheel parallel
to its periphery, in which groove corresponding shaped bolt heads are placed,
the bolts of which pass outwards from the same through a proper shaped

page_text: clamp, between the upper end of which and the raised lip of wheel the cam
pieces are inserted and held by screwing the nut of said bolt firmly up against
the clamp. The clamps can be set at any desired position on the wheel, and
can be removed therefrom at pleasure. Sixth, arranging the platform on
which the board as fast as cut is received in any proper manuer to permit it to
be moved under the main cylinder, so that the cutters can be easily reached,
and thus readily adjusted when desired. Seventh, in the use of a horizontal
feed bar moving in suitable guiding grooves of the platform, from which the
pasteboard is fed to the cutters, which feed bar is actuated through suitable
devices connected with the driving power of the machine in proper manner
to push and slide the pasteboard to the cutter at the desired time.
Having thus stated in general terms the most important features and
principles of the present Invention, other parts of which, but of a minor
character, will be herein-after explained, I will now proceed to describe them
in detail, and as the machine belonging to the fifth part of this Invention, as
before stated, embraces more generally and fully the many and various por-
tions thereof, it will be first fully described, and then in connection therewith
the modifications in this arrangement and construction, together with what
additions can be made to it. This machine is shown in accompanying Sheet of
Drawings, Sheet 1.
Fig. 1 is a front elevation, Fig. 2 a plan view, and Fig. 3 a sectional
elevation, taken in the plane of the line x, x, Fig. 1; Figs. 4, 5, 6, and 7 are
detail views, partly in isometrical perspective and partly in section, repre-
senting the modes of constructing and attachment of the cutters to the cutter
bar and of the cam wheel respectively.
In these Figures, A is the frame, consisting of uprights united or braced
laterally by means of cross pieces. The frame supports the table B in front
of the cutter cylinder C in the manner usual in most machines of similar
character. At either side of the table there are standards D, to which are
attached the cutter bars E, E', that is to say, one in front or towards the table
and the operator, and the other in the rear towards the delivery end of the
machine. To the cutter bars are secured by the means herein-after described
rotary cutters, the axes of which are in vertical planes with the axes of the
eutter rollers underneath, each set of cutters having a cutter cylinder. In this
instance two cutter rollers are used, one behind the other, their upper
peripheries being tangential to a horizontal plane in comtinuation with or
slightly above the table before referred to. The back roller F revolves in
fixed bearings, and is geared by means of a band and pulleys G, or by
suitable cog wheels to move in unison and in the same direction with the

page_text: cutter roller C. Underneath the latter there is arranged in suitable brackets
a cam cylinder or cam wheel H, which receives its motion from the cylinder C
by means of the cog wheels I and J. In the Drawings two wheels are shown
mounted upon a shaft at either end thereof. The wheels shown in front and
side elevation in Figs. 1 and 3, and in section in Fig. 7, are composed of a
disc a, provided with a hub b and an external circumferential flange c. On
the inner face of the wheel there is a T groove d concentric with the rim of
the wheel, into which groove are fitted bending bolts e for the adjustment of
clamp f, whereby the cam g may be set on the face of the wheel, and against
the flange thereof, in any desired position. The cams may be flanged or they
may be made tapering, so as to afford a wedge gripe to the clasp. By this
arrangement the cam may be adjusted upon the periphery of the wheel to
suit the work to be performed, their object being to raise the cutter cylinder
towards the cutters whenever in their revolution they come in contact with it.
It will also be understood that the cams may be replaced or interchanged for
various purposes. The size of the cam wheel is calculated according to the
length of the cutter rollers, which is equal to or slightly exceeding the greatest
dimensions of the pasteboard sheet generally used, the developement of the
circumference being equal to the length of the cutter rollers. The sheets of
pasteboard are fed to the cylinders and cutters by means of a feed bar K, which
is caused to move in a line parallel with the roller by means of a piece L
sliding in a groove M, which is at right angles to the feed bar. Both the feed bar
and the sliding piece L (which are rigidly connected and form a T) are united
by a hinged joint at h to the lever N, the fulcrum of which is at i. The lever
is operated by means of a tipping bar O and connecting rod P, the former
being actuated by a stud or projection Q on the cog wheel J. A spring a¹
keeps the feeding mechanism in place against the stops j in front of the
machine. It will be understood that with each revolution of the cam wheels
the feed bar is advanced by the action of the projection Q on the tipping bar O.
Provision is made for sheets of various dimensions by changing the location of
the fulcrum of the lever N, or by shortening the connecting rod P, or by both.
For this purpose a series of holes are wrought in the side of the table for the
adjustment of the fulcrum pin, and a series of holes are cut in the connecting
rod P for the insertion of the connecting pin k, also in the table for the
stops j. In rear of the machine, and under the cutter rollers C and F, are two
cross bars R, R', having transverse dovetail grooves l, into which are fitted
sliding rods m, to which is attached a platform n, provided at the rear end
with a guard or stop board v. An incline p is also arranged in rear of the
second roller and above the table n, which for that purpose is drawn out the

page_text: required distance to contain the cut pieces. When the cutters on the cutter
bar in the rear of the machine require additional adjustment, the operator
may approach the cutters by sliding the platform back under the rollers.
The mode of attaching the cutters to the cutter bar so as to allow of lateral
and vertical adjustment may be effected either with or without a cutter stock.
The former mode is represented in Fig. 4. The cutter holder q is bent so as
to carry the rotary cutter under the cutter bar directly over the cylinder; from
the upper part starts a screw r, which is mounted by a nut 3 recessed on the
side, so as to form a collar or neck therein. In the rear the cutter holder is
provided with a vertical tongue t, which corresponds to a vertical groove in
the cutter stock u. The latter has on the side facing the cutter bar, a tongue
or projection fitting the outer part of the horizontal T groove in the cutter
bar; through this projection, passes toward the front, and through the orifice y
of the cutter holder, a binding bolt x. On top of the stock a fork projects
forward, embracing the collar of the nut s. It will be understood that the up-
and-down adjustment is effected by the nuts, while the lateral adjustment is
performed by moving both the stock and the holder in the groove W, and by
then applying the binding screw studs 1 and 2 lapping over and under the
cutter bar, may be applied to the stock for the purpose of giving greater
rigidity to the adjustment. The other mode of adjusting the cutters dispenses
with the use of the stock. The arrangement shown in Figs. 5 and 6 illustrates
this mode of adjustment. The cutter holder, which may be
straight or bent,
has a vertical groove 3 in the rear, into which groove fits a stud 4, which in
its turn is susceptible of a lateral motion in the cutter bar by having its rear
end engaged in a dovetail groove 5 in the face of the cutter bar. AT groove 6,
running parallel with the forner, is cut in the face of the cutter bar, and
contains a laterally sliding binding bolt 7, which passes through the slot 8 in
the cutter holder. An L-shaped groove is cut in the top of the cutter bar,
and contains a forked lever 10 clasping a collar nut 11 on the screw 12 of the
holder, whereby the vertical adjustment of the cutter is effected in a manner
similar to that before described. The operation of the machine may be
understood from the preceding description of its construction and arrangement,
and of the function of the several parts referred to. I would, however, observe
that all the parts being properly adjusted, the operation is entirely or nearly
so automatic, it only requiring that the sheets, properly trimmed, be placed on
the table against the guages provided for that purpose. Supposing, therefore,
the machine is to be in ruuning order, the sheet of board will be automatically
fed to the cuttors by the feed bar a, the right moment when the necessary
score or through cut is 'to be applied. The cutter will more or less indent:the

page_text: sheet according to the position of the roller underneath, which position is
determined by the cams of the cam wheel, as before described. The first
series of cutters, that is to say, the cutters above the movable cylinder,
alternately cut and score the sheet. The dividing of sheets is effected by a
second series of cutters in combination with the second cylinder. In this way
a sheet may be cut, scored, and divided at one operation, or by only once
passing it through the machine.
In Sheet 2 of the Drawings are shown modifications of the mode of securing
the cutter stocks or holders to the cutter beam, and of their arrangement with
regard to each other, and also graduated scales or rules placed in suitable
positions in relation to the edges of the cutters, for the purpose of accurately
measuring and guiding them in the horizontal adjustment of their stocks or
holders upon the cutter beam; Fig. 1 being an end view of a machine having
them applied to it; Fig. 2 a plan or top view; Figs. 3, 4, and 5, sectional
views of parts somewhat enlarged from the scale of Figures 1 and 2, and
Figs. 6 and 7 detached parts still further enlarged.
A in Sheet 2 is the cutter roll; B³, the cutter beam supported at each end
in standards C2, C³.
In Figs. 3, 4, and 5 are shown two cutter holders, one Ds straight and
placed inclined upon the cutter beam B', and the other D³ placed upright
upon the opposite side of the cutter beam, but bent or made of an angular
shape at its lower end to bring its cutter a³ into the proper position upon the
cutter roll in relation thereto and to the cutter at of the holder D'; but I do
not confine myself to either form, as both may be straight and inclined as D³,
or both bent as D³, or either one inclined and the other bent, it only being a
matter of change in the form of the beam. To fasten the cutter holder to the
beam I make a groove in the sides of the beam, in which is placed a T-
shaped guide d³, see Figs. 6, 7, and 8, the tail of the T lying upon the side of
the beam, and projecting wholly therefrom. In the cutter holder is a groove e³,
fitting and setting over the tail of the guide d³, so as to keep the cutter holder
perpendicular. In the beam B³ I make a second T-shaped groove f³, into
which sets and fits the head of a bolt g³, extending out through a slot in the
cutter holder, and having on its outer end a nut h³, which when screwed down
upon the cutter holder binds and securely holds it to the beam, and when
loosened allows the cutter holder to be slid along upon the beam, either to the
right or left and to any desired position, where it is then set by again turning
down the nut against it, as before explained.
In order to raise or lower the cutter from or toward the cutter roller
according as it may be desired to cut entirely or only partially through the

page_text: pasteboard, I form upon the top of the cutter holder a screw i³, on which
screw is fitted a nut n³,having its upper edge milled for convenience in turning
it, and with a groove entirely around it fitting into a projecting forked piece o³,
see Fig. 4, of the beam held in a dovetail groove p³ of its upper side, so that it
can be moved freely along thereon. By turning the nut down upon the
screw the nut will rest upon the fork o³, consequently drawing the cutter
holder up, and by reversing the direction in which the nut is turned the
opposite result will be effected, that is, the holder forced down, as is obvious
without further explanation.
In Fig. 4, and upon the opposite side of the beam to the arrangement of
the cutter thereon above described, a slight modification is shown, which
consists in lieu of using the said sliding forked arm o³ for holding the nut, I
insert the nut in a slot made in the beam, forming a lip ³ for the groove in the
nut, and also place a bar N³, constructed with a similar slot and lip as described,
for the beam outside of the nut and parallel with the beam, with which
arrangement the same results can be accomplished as above described.
For convenience of adjusting the cutters for the cutting of different widths,
and also to enable them to be more accurately set upon the beam, I place
a graduated scale R³, see Fig. 4, supported in guides S³ upon one side and guides
on the standards to support the ones upon the other side, see Fig. 1, by means
of which the scales can be brought very near to the cutters, as is obvious.
The graduated scale can be placed on top of the cutter beam, and index
hands or pointers may be used in connection with the cutter stocks
for securing an accurate adjustment, or the scale may be made upon the side
faces or surfaces of the beam, as will be herein-after more particularly referred
to in connection with Drawings.
In the Drawings Sheet 3 the portions of the present Invention embraced
under and in the third and fourth parts of this description, together with a
portion of that included in the second part, the other portion having been
described in connection with Sheet 2 of the Drawings, are shown, Fig. 1 being

page_text: after it is cut; K', the cutter beam, supported at its two ends by standards L*,
shown enlarged in Figs. 3, 4, and 5; M, M³, are the cutter stocks, the one
M* being constructed so as to allow the use of a straight cutter holder m*,
and the other M5 so as to allow the use of a bent cutter holder m. The
cutter stock M' is secured to the beam K* in the following manner:-A slight
incline or groove is made upon the under side of the beam, see Fig. 4, and
from the cutter, so as to hook into it upon the upper side, and also a groove in
which is placed a shoe a; the upper end of the stock M is set over the beam,
and through its projection a set screw f' is placed, so as to set down upon
and into a seat of the said shoe a", so that when the said screw is turned down
upon the shoe it will hold the stock firmly in its place, the screw when
loosened allowing the stock M to be freely moved along and upon the beam.
The stock M³ is held in the following manner:-This stock has projections
9, 9, above and below the beam K, or a tongue and groove, as in Fig. 12,
and in the side of the beam a T groove he is made, in which is placed the
head of a bolt 2, over which bolt the stock M is placed, the bolt projecting
through it and also through the cutter holder m, then by turning a nut No on
the bolt and down upon and against the cutter holder m³, the stock and
bolder will be firmly bound to the beam, and be susceptible of being moved
upon the beam by simply loosening the said nut. In the face of the cutter
stock is a dovetail guide, see Fig. 6, and a corresponding groove upon the
cutter holder, fitted so that the holder will slide freely thereon, and in the
lower end of the holder is a slot, in which is hung a cutter oº, so as to revolve
freely upon a centre pin or pivot p"; in the upper end of the cutter holder is
a screw p', which sets through a projection R' on the stock M, on which
screw are two nuts,, one above an1 the other below the said projection,
for the purpose of adjusting the cutters to raise or lower as it is required to
cut the pasteboard entirely or only partially through its thickness; the two
nuts when turned hard against the said projection R holding the cutter firmly
and securely in its place. If desired to raise the cutter from the roller, loosen
the lower nut and turn down the upper one, and reverse the operation if desired
to lower the cutter, a slot in the holder allowing a movement over the bolt 2³.
In Figs. 7 and 8 a modification of the manner of raising and lowering the
cutter is shown, and it consists in using in lieu of the two nuts r, 26, a slot in
the projection R', on which is placed a single grooved nut to, by the turning
of which up or down the cutter holder is accordingly raised or lowered. The
cutter holders may be made straight or bent, or bent in place of straight, or vice
versa, the cutter stocks being constructed accordingly, and with either the
adjustments shown in Fig. 4 or in Figs. 7 and 8.

page_text: In Fig. 9 is shown a cutter, the periphery of which is made of a zig-zag
shape, which it is quite desirable to use in the cutting of the lower edge of
the sheet of pasteboard which is to form the side of cylindrical boxes in
order to fold it more readily under the bottom. In Figs. 3 and 5 graduated
scales are shown upon the sides of the cutter beam for facilitating the setting
or adjustment of the cutter stocks thereon.
In pasteboard cutting machines heretofore the upper feed roller has been
allowed to rest upon the lower feed roller, so that when the board was
introduced in and between the rollers near one end of them, the upper roller
at the other end would rest upon the lower roller at such end, consequently
the two rollers would not be parallel with each other, and the upper one would
press harder upon the inner edge than the outer edge of the pasteboard,
whereby the board would be unevenly fed into and through the machine,
causing it to be cut in a curved shape in lieu of straight, the guides upon the
table being depended upon to properly conduct the pasteboard, and to avoid
this difficulty the boxes 7, which support the bearings of the upper roll, are
suspended on screws w7, the heads of which rest upon the top of the standards,
so that by turning them in the proper direction the boxes will be raised or
lowered as the case may be, and thus the roller be set in any desired plane
with regard to the under roller and parallel therewith throughout its length,
the roller always resting upon the pasteboard sufficiently to draw it through
the machine.
In Sheet 4 of the accompanying Drawings some modifications of and
additions to the machine herein-before particularly described, and which was
illustrated in Sheet 1, are shown, Fig. 1 being a view of one side of the same,
and Fig. 2, a transverse vertical section taken in the plane of line a, a, while
Fig. 3, Sheet 4, is a plan, and Fig. 4, Sheet 4his, an end view of the same.
These modifications and additions consist,-
1st, in so securing the tables to the machine that they can be readily
detached therefrom, in order to enable the cam wheels for raising the cutter
roller to be more easily adjusted.
2nd, in graduating the edge or periphery of the cam wheel, as plainly
shown at H, Fig. 1, to enable their cam pieces to be adjusted and set with
more accuracy on the wheels.
3rd, in the use of an adjustable stop B, for the purpose of starting each
sheet of the pasteboard (when pushed to the cutters) alike and at the same
time, so to be similarly and equally operated upon by the claws.
4th, in the use of only one beam in lieu of two, as shown in Sheet 1, this
beam being made of sufficient width to bring the cutters over each cutter

page_text: cylinder. As the parts composing this machine have been already so fully
and plainly described, the adaptation of the above-recited modifications and
additions will be manifest without further explanation.
Having described the nature of this Invention, and the manner of per-
forming the same, I declare that what I claim as the Invention to be protected
by the herein-before in part recited Letters Patent,--
1st, the method herein described of cutting pasteboard by combining with
fixed cutters and revolving cylinder a mechanism for raising and lowering the
said cylinder to and from the cutters at given intervals of space, to more or
less or not at all indent the pasteboard, or to produce a through cut at
pleasure, substantially as set forth.
2ndly, combining in one machine two cutter bars, provided with adjustable
or fixed cutters, with two cylinders, geared so as to revolve with equal velocities,
one of the said cylinders revolving in fixed bearings, while the other, actuated
by suitable mechanism, is raised to or lowered froin the cutters, as herein
described.
3rdly, in combination with adjustable or fixed cutters and revolving cutter
cylinder, I claim a cam cylinder or wheel revolving in unison with the cutter
cylinder, and actuating it to more or less impinge against the cutters at given
intervals of space, substantially as set forth.
4thly, the combination with the cutters, cutter cylinder, and cam wheel a
feed bar actuated by the cam wheel or any part moving in unison therewith, in
such manner as to feed the sheet to the cutters automatically and at proper
intervals of time during the revolution of the cam wheel to receive the
through and score cut between given points, substantially as set forth.
5thly, the combination of the grooved and flanged disc with detachable
cams and clamps, and screw bolts to fasten the cams to the periphery of the
wheel, substantially as set forth.
6thly, in combination with a machine for cutting pasteboard, I claim a
sliding and adjustable platform or table for receiving the scored and cut
sheets, the arrangement being such that the said table may be slid under the
main cylinder, so as to admit of the operator approaching the cutters to
adjust them, substantially as set forth.
7thly, I claim the combination of the cutter holder and stock fitted together
by means of a vertical tongue and groove, with one or more horizontal guide
tongues on the back of the stock, and fitting and sliding in a corresponding
groove or grooves in the cutter bar, or the projecting studs on the cutter
stock lapping over and under the cutter bar, together with a binding bult
passing through the central guide tongue, substantially as set forth.

page_text: 8thly, the forked arm and grooved screw nut working therein, in com-
bination with the inverted T-groove in the side of the cutter bars with the
binding screw bolts and nuts, substantially as described for the purpose specified.

ment of the cutter stock, by combining with the cutter bar having two side
grooves and one top groove a cutter holder, slotted or grooved vertically for
adjustment on a binding bolt and horizontally sliding cross or T stud, together
with the horizontally sliding fork and collar screw for the vertical adjustment
of the cutters, substantially as set forth.
10thly, the attachment to the cutter bar of the parallel or horizontal beam
or cap set at a distance apart to admit of the groove of the screw nut, in
combination with grooves in both the said cutter bar and beam, to admit of the
collar of the screw nut, the whole being arranged for operation substantially
as set forth.
11thly, the mode herein described of locating and holding a rule or scale in
its proper relation with respect to the cutters, by combining with the cutter
bar and uprights brackets, or the equivalents thereof, in the manner sub-
stantially as herein-before shown and described.
12thly, the ziz-zag cutter, constructed and arranged in relation to the
cutter holder, cutter stock, cutter bar, and main cylinder, so as to operate in
the manner and for the purpose described, and whether the same is used in
connection with scoring or ordinary cutters, substantially as set forth.
13tbly, the combination and arrangement for the adjustment and suspension
of the upper feed roll B, substantially as set forth and described, and for the
purpose specified.
