Combined Paper Cutter and Folder.
I, JOSEPH VICTOR, Gentleman, residing at No. 1447 Old Manchester Road,
in the City of St. Louis, State of Missouri, U.S.A., do hereby declare the nature
of this invention and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement:-
My invention relates to a machine for automatically folding, cutting or
perforating into equal lengths a strip of paper as it passes through the machine
from a roll, said roll of paper being suitably located adjacent the machine.
An object of my invention to construct a machine that when paper in a
continuous strip is passed through the same, said paper will be either folded, cut or
perforated as desired in equal lengths, said folded or cut portions being deposited
at a central point below the machine.
A further object of my invention is to provide in such a machine a setting
mechanism, whereby the length desired to be given to the cut, folded or perforated
sections of paper may be quickly and easily regulated and adjusted.
A further object of my invention is to construct a machine that is especially
applicable and adapted to be used in connection with newspaper printing presses
of the improved type. When my invention is used in this connection, the printed
paper which issues from the printing press in a continuous strip is passed through
my machine and the same cut and folded at the proper places.
My invention consists in certain novel features of construction, combination
and arrangement of parts, hereinafter described and designated in the claims.

Fig. 15 is a vertical sectional view taken approximately on the indicated
line 15-15 of Fig. 5.
Referring by numerals to the accompanying drawings, 1 indicates the side
frames of my machine, they being identical in size and construction. These side
frames are preferably rectangular in form, of skeleton construction, and provided
with the enlarged bases or feet 2. The top edges of the said frames 1 are slightly
raised, as indicated by the numeral 3, and upon these raised portions are positioned,
by means of bolts or in any suitable manner, the journal bearings 5. Depending
from the under side of the top bars of the side frames 1 are integrally formed
journal bearings 6.
Passing through one pair of the oppositely positioned journal bearings 5 is a
shaft 7, upon which and between the side frames is rigidly mounted a roller 8,
the same being covered as desired with cloth, paper, rubber, or analogous
materials.
The side of the machine shown in Fig. 2 may be properly termed the front
side.
The shaft 7 extends some distance beyond the bearing 5 and from the front
side of the machine, and is provided on its outer end with tight and loose pulleys 9
and 10.
Rigidly mounted upon the shaft 7 between its front bearing and the tight
pulley 9 is a gear-wheel 11. Passing through the remaining pair of oppositely
positioned bearings 5 is a shaft 12 upon which and between the side frames 1 is
rigidly mounted a series of rubber or leather faced wheels 13, the same comprising
the circular body portions 14 and elongated hub 15, through which passes a set-
screw or bolt 16, whereby said wheels may be locked at any point upon the shaft 12.
The peripheral grooves 17 formed in these wheels 13 are adapted to receive
rubber, leather or analogous bands 18, the same being adapted to contact with the
face of the roller 8. These wheels 13 are approximately of the same diameter as
is the roller 8.
Parallel guide-bars 19 and 20 extend horizontally from one of the upright
portions of the side frame to the other and are bolted to said frames by means of
suitable bolts 21. These guide-bars 19 and 20 are a slight distance below the
center of the height of the side frames 1.
The upper bar 19 on the front of the machine is graduated or scaled in both
directions from the center, these portions being provided with indicating numerals
as clearly shown in Fig. 2.
At a point in the longitudinal center of the top part of the side frames 1 and
extending from one of said side frames to the other is a shaft 22, said shaft
extending a slight distance beyond both of the side frames 1 and there has rigidly
mounted thereon adjacent the side frames 1 and 2 the depending arms 23, the
lower ends of which are slotted, as indicated by 24.
Passing through one of the depending bearings 6 is a short shaft 25, to the
outer end of which and in vertical alignment with the gear-wheel 11 is rigidly
mounted a gear-wheel 26.
Pivoted to the front side frame is a slotted arm 27, the same being horizontally
positioned at a point between the gear-wheels 11 and 26.
Mounted upon a longitudinally adjustable bolt 28, the same passing through the
slot in the arm 27, is an intermediate gear-wheel 29, the same meshing with the
gear-wheels 11 and 26. At any time desired a different sized gear-wheel may be
positioned upon the shaft 25, thereby easily and efficiently changing the speed of
the machine. A smaller gear-wheel 26 is shown in Fig. 3.
On the outer end of the shaft 22 and outside the gear-wheel 26 is mounted a
depending arm 23. A connecting bar or link 30 is bolted to this front arm 23ª
and also to the face of the gear-wheel 26 at a point a slight distance from the
ceuter of said gear-wheel 26. As the depending arms 23 are rigidly mounted upon

page_text: Osemnating movement.
Mounted for rotation in the remaining depending bearing 6 and extending a
slight distance rearwardly is a short shaft 31. Upon the inner end of this
shaft 31 is rigidly mounted a gear-wheel 32, the same being provided on its inner
face with a lug 33. This gear-wheel 32 meshes with a similar gear-wheel 34 that
is rigidly mounted upon the inner end of the shaft 25, said gear-wheel 34 also being
provided with a lug 35 in every way identical with the lug 33.
A bar 36, having at its central point a depending lug or portion 37 and its
ends 38 slotted, is mounted for longitudinal movement on the inside of the front
side frame and the inside of the gear-wheels 32 and 34. This is accomplished by
passing bolts 39 provided with washers 40 through the slots 38 in the ends of the
bar 36 and into the front side frame.
Mounted for longitudinal adjustment upon the bar 36 and near the inner
ends of the slots are rectangular blocks 41, the same being provided with set-
screws 42.
Positioned upon the shaft 22 between the side frames 1 is a tube 43, the purpose
of which will be presently shown.
Bolted to the inner sides of the top portions of the side frames 1 and inclining
and depending therefrom to a point adjacent the meeting point of the bars 19
with the upright portions of the side frames are guide-ways 44, the same being
U-shaped in cross-section.
A rod 44 extends from one of these guide-ways to the other and is adapted to
vertically move therein in a manner presently to be described.
Referring now to Figs. 4 and 11, I will describe the construction of the
longitudinally moving bar and its connections with the slotted ends of the depending
and oscillating arms 23.
This longitudinally moving bar or carrier as it may be called is composed of
four rectangular metallic bars 45, said bars 45 being paired, a space left between
the two pair and the outer and inner edges of the outer and inner bars being
beveled, as indicated by the numeral 46. The pairs of bars 45 are held a slight
distance apart by the interpositioning of a small rectangular plate or washer 47
and a pin or screw 48 passed through the bars 45 and the plate 47. Positioned
between the ends of the paired bars is a block 49, from which extends in a plane
corresponding to that of the bars 45 a shaft 50. The pairs of bars 45 are bolted
to this block 49 by means of screws or bolts 51.
The end of the shaft 50 toward the frout side frame passes through a plate 52
that slides along the inner faces of the bars 19 and 20 and from thence into a
block 53, said block being provided with flanges 54 which slide along the outer
faces of the bars 19 and 20 the plate 52 being securely positioned upon this
block 53 by means of screws or pins 55. The end of the shaft 50 passes nearly
through the block 53 and is allowed to freely turn therein.
Mounted upon the pin 55, the same being rigidly fixed to the outer face of the
block 53, is an anti-friction roller 56 which is adapted to operate in the slot in
the lower end of the oscillating arm 23 on the front side of the machine. The
rear end of the longitudinally moving bar and the shaft 50 are fitted in the
following manner :
A bifurcated arm 57 comprises a hub 58 through which the shaft 50 passes and a
rectangular portion 59 extending vertically from the hub 58. Formed integral
with the portion 59 and extending upwardly therefrom is a U-shaped portion 60.
Extending horizontally from the portion 59 is a pin 61. By means of a pin 62
passing through the hub 58 and the shaft 50, the bifurcated arm 57 is rigidly fixed
upon said shaft 50.
A plate 63 provided with a vertical extension 64 has formed integral with its
lower end an inwardly projecting block 65 that passes between the bars 19 and 20
and contacts with the inner face of the hub 58. Extending from the upper end of

page_text: the vertical portion 64 is a pin 66, to the outer end of which is connected one end
of a coil-spring 67. The lower end of this coil-spring is secured to the outer end
of the pin 61.
Mounted for rotation upon the outer end of the shaft 50 is an anti-friction
roller 68 which is adapted to operate in the slot in the lower end of the rear
arm 23.
Mounted for longitudinal adjustment between the bars 19 and 20 on the rear side
of the machine and at both sides thereof are blocks 69 from which extend toward
the center arms 70, upon the inner ends of which are mounted anti-friction
rollers 71 the same being directly in the path of travel of the bifurcated
arm 57.
Mounted between the bars 19 and 20 on the front side of the machine and near
the ends thereof are blocks 72. These blocks 72 are capable of being longitudinally
moved along said parallel guide-bars 19 and 20.
Mounted between the blocks 69 and 72 are spring-actuated jaws and knives, or
perforators, of which I make use in carrying out my invention, and which will now
be described.
The knife comprises the rectangular bar 73 from which projects in a horizontal
plane the knife-edge 74. This knife-edge may be formed in the ordinary manner,
or serrated, as it is shown in Fig. 6.
The bar 73 is detachably held by means of screws 75 passing through the
forward ends of the end-clamps 76 and 77. The top plates of these clamps 76
have formed integral therewith the raised portions 78 between which is formed a
rectangular notch 79. The lower plates 77 that are used in constructing the
end-clamps are rectangular metallic bars and are rigidly held at their rear ends to the
top plates 76 by means of bolts 80 passing theretbrough. Blocks 81 are interposed
between the rear ends of the upper and lower plates 76 and 77 in order to establish
and maintain the correct space between said plates.
A plate 82 passes from one of these end-clamps to the other and has its ends
positioned in the spaces immediately in front of the blocks 81 and between the top
and bottom plates 76 and 77.
Positioned on both sides of this plate 82 and held thereto by means of pins 83,
are the top and bottom clamping jaws 84 and 85, the same extending beyond the
rectangular bar 73 and there provided with widened portions 86 that contact with
both of the knife-edges 74. At equal distances along the length of the plate 82
and extending upward through the upper jaw 84 are pins 87, the lower ends of
which are screw-threaded and firmly seated in the plate 82. These pins extend
upward a slight distance and have positioned thereon adjacent the upper clamping-
jaw a washer 88 which forms a seat for a coil-spring 89, the same being held upon
the pin 87 by means of a thumb-nut 90 which is adapted to be located upon the
screw-threaded upper end 91 of the pin 87.
At regular intervals in the length of the upper and lower jaws 84 and 85 are
stamped or pressed the inwardly extending lips 92, thus forming the inclined
planes 93 for the rear edges of the rectangular bar 73 to engage against when the
same is thrown rearwardly. These jaws 84 and 85 are so fitted upon the pins 83 as
that the front ends of said jaws will part or open a slight distance and the rear ends
thereof will not bind upon said pins 83.
Pivoted on rods 93" that extend from the blocks 69 to the blocks 72 are bell
cranks 94, the vertical arms 95 of which are adapted to enter the rectangular
notches 79 in the top plates of the end-clamps.
The horizontal arms 96 of these bell-cranks are made somewhat longer than the
vertical arms, and are provided at their outer ends with vertical bores.
Pivoted on the rods 93" adjacent the inside portions of the blocks 72 are vertical
arms 98, the upper ends of which contact with the blocks 42 previously mentioned.
The lower ends 99 of these arins 98 are adapted to engage in the rectangular
notches 79 formed in the upper sides of the upper plates of the end-clamps.
Horizontal arms 100, counterparts of the horizontal arms 96, are formed integral

page_text: with the vertical arms 98 and are of the same length as are the horizontal arms 96.
Riveted to the inner faces of the plates 69 and 72 are outwardly extending
horizontal bars 102, and to the outer euds of which are secured coil-springs 102,
the upper ends of said coil-springs being secured to eyes formed in the ends of
rods 103 that pass through the vertical bores in the horizontal arms 96 and 100.
The upper ends of these vertical rods are screw-threaded and adapted to receive
winged-nuts 103*.
The paper shown passing through the machine is indicated by the numeral 104.
The paper is introduced between the rollers 8 and the rubber faced rollers 13,
passes downwardly around the rod 44" moving in the guide-ways 44, up and over
the tube 43, around the short shaft 22, down and between the paired bars of the
carrier, and from thence to a point between the forward ends 86 of the spring
clamping-jaws. The paper thus being introduced into the machine the various
parts in the positions as shown in Figs. 2, 5, and 9, the operation is as follows:
We will assume that it is desired to cut the paper into equal lengths and at each
end of the stroke or oscillation of the arms 23. The block 72 having been
longitudinally moved along the parallel guide-bars 19 and 20 until the desired
length of paper to be cut is indicated, the belt "A" shown in Figs. 1 and 2 is
thrown onto the tight pulley. The belt moving in the direction of the arrow
"C"
necessarily imparts motion to the shaft 7, thereby driving the roller 8 and
gear-wheel 11 in the same direction. The shaft 12 and rubber faced wheels coming
in contact with the paper, be moved in the direction of the arrow "D." The
intermediate or speed gear 29 meshing with the gear-wheel 11 will necessarily be
given motion, which it will necessarily impart to the gear-wheel 26, the same
moving in the direction of the arrow "E." The gear-wheel 34 on the inner end
of the shaft 25 will necessarily be given movement, and the same meshing with the
gear-wheel 32 will cause said gear-wheel to rotate, the direction of movement of
these gear-wheels being as indicated by the arrows "F." As the gear-wheels 26
rotate, the bar or link 30 rigidly secured to the face of same and to the vertical
arm 23 will be given motion, which will necessarily oscillate the arm 23 in the
direction indicated by dotted lines in Fig. 2. The carrier composed of the
rectangular bars 45 and end shafts 50 which are carried by the depending arms 23
will be, when the arms 23 have reached their limit of movement, thrown to a
horizontal position, or as that shown in Fig. 13, this being occasioned by reason of
one of the portions 60 of the bifurcated arm 57 contacting with the anti-friction
roller 71 on the end of the arm 70. This action easily takes place as the forward
shaft 50 rotates in the block 53 and the rear shaft 50 rotates in the block 65. The
points of the upper pair of rectangular bars 45 will enter a short distance between
the front ends 86 of the clamping-jaws 84 and 85, they being opened to receive
the forward ends of the rectangular bars 45 in the following manner:
Simultaneous with the movement of the arms 23, the gear-wheels 32 and 34 are
rotating and the lug 33 on the gear-wheel 32 is commencing to bear and engage
against the end of the depending portion or lug 37 of the bar 36. This will
necessarily move said bar longitudinally in the direction of the arrow "G." This
will necessarily cause the block 42 on the left hand end of the longitudinally
moving bar 36 in Fig. 9 to contact with the upper end of the vertical bar 98.
This movement being continued, said vertical bar 98 will be thrown to the position
as indicated by dotted lines in Fig. 9. The lower end 99 of the bar 38 engaging in
the rectangular notch 79 on the top plate 76 will cause the rectangular bar 73 of
the knife to contact with and move a slight distance along the inclined surface 93 of
the lips 92. This will necessarily throw the upper and lower clamping-
jaws 84 and 85 apart as clearly shown in Fig. 13, and allow the forward points of
the upper pair of rectangular bars 45 of the carrier to enter therein. These various
movements having taken place, the arms 23 by reason of their connections begin
movement in a reverse direction to that just described. As the upper pair of
bars 45 of the carrier leave the forward ends of the clamping jaw, they will leave the
paper clamped therein, and as the reverse movement is continued and the bifurcated

page_text: arm 57 leaves the roller 71, said bifurcated arm will reassume a vertical position by
reason of the tension of the coil spring 67.
Simultaneous with this reverse movement of the arms 23, the lug 33 on the
gear-wheel 32 having passed the depending portion 57 of the longitudinally moving
bar 36, the tension of the coil-spring 102" will cause the vertical arın 98 on the
left hand side of the machine shown in Fig. 9 to reassume its normal position.
Thus with the receding movement of the upper pair of rectangular bars 45 of the
carrier, the clamping-jaws are closed, the knife thrown forward, and the paper cut.
The arms 23 are now carried to the other side of the machine and an operation in
every way similar to the one just described gone through with.
Whenever the paper is cut the cut edges thereof are held between the
clamping-jaws until they are again opened and about to receive one pair of the
rectangular bars 45 of the carrier.
When a knife is used on both sides of the machine, the paper will be cut with
each stroke or movement of the arms 23. Should the knife-edge 74 be removed
from the bar 73 on one side of the machine, then the paper will only be folded on
that side of the machine, and cut on the other.
Should the knife-edges be dispensed with on both sides of the machine, then
the paper will be folded with each movement of the arms 23 and the clamping-
jaws 84 and 85.
If desired, a bar similar to the bar 73 but provided with a series of pins may be
introduced between the clamping-jaws and by this means the paper perforated and
folded instead of cut.
The rod 44 acts only as a tension for the paper.
In Fig. 1 I have shown the roll of paper upon standards. This is not essential,
however, as the paper may be fed into the machine in any suitable manuer.
Thus it will be seen how I have constructed a machine for cutting, folding or
perforating paper that possesses superior advantages in point of simplicity, durability
and general efficiency.
