We HERBERT JAMES SALMON, JOHN CAPPER and WILLIAM HENRY DUFFETT,
all of the City of Manchester in the County of Lancaster, Printers Machinists do
hereby declare the nature of said invention for "IMPROVEMENTS IN MECHANISM
"OR ARRANGEMENTS FOR FEEDING PAPER OR OTHER MATERIAL FROM THE WEB TO
PRINTING MACHINES HAVING RECIPROCATING TYPE OR OTHER PRINTING SURFACES,
AND CUTTING OR DIVIDING THE SAME INTO LENGTHS," to be as follows:-
The paper or other material to be fed to the printing machine according to our
invention, is in a continuous roll of considerable length and is thus said to be in
the "web."
According to one modification of our invention the roll is arranged in suitable
bearings, on the framing of, or opposite to the printing machine, to which it is to
be fed, and its end is passed through a pair of rollers which pinch the paper or
material.
The bearings of these rollers are arranged on a slide or in levers, or in a frame
which can oscillate or reciprocate, and move the rollers to and from the gripper or
impression cylinder of the printing machine.
Between the rollers when at their nearest approach to the gripper cylinder and
the latter, a knife or other suitable edge is arranged in slides or on arms on a shaft,
the edge extending across the paper or material, and below this knife or edge there
is a soft metal or other surface or other arrangement for the edge of the knife to
cut or act against-The knife or edge is held up above the paper, and when it is to
cut. or divide the paper, it is allowed to descend upon it being drawn or forced
down by one or more springs-The knife is held up by an arm or lever from or
connected with it, which rests upon a cam surface on the axis of the gripper or
impression cylinder, or on an axis in gear with that cylinder, and this cam is so
shaped that the arm or lever resting upon it will be allowed to drop suddenly at
the desired time and thus cause the knife or edge to come upon and cut or divide
the paper or material,

page_text: This cam for the knife or edge is arranged so as to be readily adjustable and
secured on its axis forward or backward to allow the knife or edge to drop or act
sooner or later, and thus cut a longer or shorter sheet as required.
The slide frame or levers carrying the bearings of the said rollers is actuated by
a cam or other arrangement of mechanism and when moving the rollers towards
the gripping or impression cylinder the rollers do not rotate but act as nippers to
hold and push forward the end of the paper or material protruding from them until
the end enters and is taken by the grippers of the impression or gripper cylinder,
and when the latter draws the paper or material forward, the rollers rotate and
they are moved backwards at the same time, and when the required length has
passed the knife or edge descends, and thus severs that length from the web the
end of which is again pushed forward to the grippers when ready to receive the
next sheet and so on for each length.
Pinching arrangements are or may be substituted for the rollers which will
pinch the paper or material when moving in one direction to feed the paper to the
grippers but open to allow it to pass freely. when drawn forward and when the
slide or frame is moved back in the other direction.
According to another modification of our invention the rollers are or may be
arranged in stationary bearings, near or close to the knife or edge, the rollers being
rotated from a cam or crank or other motion to feed the paper to the grippers on
the impression cylinder, and when they have taken it, the rollers are free to be
rotated by the paper drawn in by the gripper cylinder from the web.

page_text: We HERBERT JAMES SALMON, JOHN CAPPER, and WILLIAM HENry Duffett
all of the City of Manchester in the County of Lancaster, Printers Machinists,
do hereby declare the nature of said invention for IMPROVEMENTS IN MECHANISM
OR ARRANGEMENTS FOR FEEDING PAPER OR OTHER MATERIAL FROM THE WEB TO
PRINTING MACHINES HAVING RECIPROCATING TYPE OR OTHER PRINTING SURFACES
AND CUTTING OR DIVIDING THE SAME INTO LENGTHS," and in what manner the
same is to be performed, to be particularly described and ascertained in and by
the following statement:-.
to
. The paper or other material to be fed to the printing machine according to
our invention, is in a continuous roll of considerable length and is thus said to be
in the "web."
According to one modification of our invention the roll is arranged in suitable
bearings on the framing of or opposite to the printing machine to which it is
to be fed, and its end is passed through a pair of rollers which pinch the paper or
material.
The bearings of these rollers are arranged on a slide or in levers, or in a frame
which can oscillate or reciprocate, and move the rollers to and from the gripper or
impression cylinder of the printing machine.
Between the rollers when at their nearest approach to the gripper cylinder and
the latter a knife or other suitable edge is arranged in slides or on arms on a shaft,
the edge extending across the paper or material, and below this knife or edge there
is a soft metal or other surface or other arrangement for the edge of the knife tö
cut or act against.
The knife or edge is held up above the paper and when it is to cut or divide the
paper it is allowed to descend upon it being drawn or forced down by one or
more springs. The knife is held up by an arm or lever from or connected with it,
which rests upon a cam surface on the axis of the gripper or impression cylinder,
or on an axis in gear with that cylinder, and this cam is so shaped that the
arm or lever resting upon it will be allowed to drop suddenly at the desired
time and thus cause the knife.or edge to come upon and cut or divide the paper
or material.
This cam for the knife or edge is arranged so as to be readily adjustable and
secured on its axis forward or backward to allow the knife or edge to drop or act
sooner or later, and thus cut a longer or shorter sheet as require.l.
The slide frame or levers carrying the bearings of the said rollers is, actuated by.
a cam or other arrangement of mechanism and when moving the rollers towards
the gripping or impression cylinder the rollers do not rotate but act as nippers to
hold and push forward the end of the paper or material protruding from them
until the end enters and is taken by the grippers of the impression or gripper
cylinder, and when the latter draws the paper or material forward the rollers
rotate and they are moved backwards at the same time, and when the required
length has passed, the knife or edge descends and thus severs that length from the
web, the end of which is again pushed forward to the grippers when ready to receive
the next sheet and so on for each length.
Pinching arrangements are or may be substituted for the rollers which will
pinch the paper or material when moving in one direction to feed the paper to the
grippers but open to allow it to pass freely when drawn forward and when the
slide or frame is moved back in the other direction.

page_text: Fig 1 is a partial side elevation, fig 2 is a partial side sectional elevation looking
from the same side as that shown by fig 1, and fig 3 is a partial side elevation of
the opposite side of the machine to that shown by fig. 1.
The framing A of the machine is shown with a part of. it supposed broken away
between its highest and lowest part in each figure.
a represents the rack of the reciprocating type bed or other printing surface;
6 the wheel on the impression cylinder; c the impression cylinder, c¹ the gripper
shaft, and c the grippers, and d is the cam shaft of the machine.
The above parts referred to by letters and figures are ordinary parts of machines
'with reciprocating type or other printing surfaces. e is an inclined iron plate or
table secured to the side frames A upon which stands or brackets e¹ are cast or
secured on each side. The stand e¹ on each side of the machine is arranged as,
'near the impression cylinder (c) as convenient and each stand e' is slotted to fit
and guide, one end of a bar f that extends across the machine, to this bar a
knife blade is secured by screws.
This knife barf is arranged to move up and down in the guide slots and its
blade cuts against a fixed blade f¹ carried on the lower part of the stand e¹ being
jointed thereto at one end, the other end being capable of movement to and from
the moving blade on f against the edge of which it is kept by the pressure of a
spring acting upon the free end of this lower blade or cutting edge f¹.
That side of the lower cutting edge f¹ that faces the upper cutting blade is
slightly inclined backwards to give clearance so that only the actual cutting edges.
come in contact as in ordinary shears.
The edge of the upper cutting blade is set by preference at a slight inclination
to the cutting edge of the lower blade f¹ so that it first begins to cut at that side
of the lower cutting blade which is jointed to the stand (e)-other arrangements.
of shears, dividers or perforators may be used if desired.
Each stand e¹ has an arm e in which a bearing is formed for a shaft e³ extending
across the framing-and this shaft e³ has two arms e secured upon it, one on cach
side, each arm being connected by a link e³ with a pivot f' on the end of the
eutter bar f.
On one end of the shaft e³ there is another arm e secured which comes against
a stud or pin e' in one. arm es of a bell crank lever having its fulcrum on a stud e³
in a part of the pedestal bracket for the impression cylinder c.
The other arm ex of the bell crank lever comes against a cam g secured on the
end of the axis of the impression cylinder.
This cam is made with a step or sudden descent so that when it has turned to
the required position the arm e* is suddenly released, then powerful springs (one
at each end) connected with the ends of the knife bar f at one end and with the
framing at the other end quickly pull down the barf and instantly cuts the
passing paper.
There is a projection f³ from each end of the cutting barf the lower ends of
which come against the plate e when the cutting bar f is suddenly released, and
the ends of these parts f³ are shod with leather or other material to soften the
blow and noise.
"
The cam g is bored out to fit upon a boss or small pulley g¹ secured on the end
of the impression cylinder shaft, and this boss or pulley part has also a boss g² the
end of which comes in a line with the outside disc face of the cam g so that a
washer on a set screw g³ in the pulley g will extend across the concentric space
between the inside hole in the cam (g) and the boss of the pulley gl and by serewing
up this set screw g³ the cam (g) is adjusted aud secured to the pulley or boss in any
required position.
When the cam g is moved one way the knife bar ƒ will descend at a later part
of the revolution of the impression cylinder c and thus cut off a longer length, and
when adjusted the opposite way the knife bar f will descend sooner and cut off a
shorter length from the web, and thus the length to be cut from the web at each
rotation of the impression cylinder is adjusted.

page_text: In that class of printing machines where the impression cylinder c rotates both
backward and forward (called "tumbler" machines) the cam g is or may be
arranged same as the disc in the "Wharfdale "Printing Machine for giving inter-
mittent rotation to the impression cylinder in such manner that when the cam g
has made a rotation in the printing direction it will remain stationary while the
impression cylinder is making its back movement, as is well understood in the
Wharfdale Printing Machine.
When the cam g is secured to the axis of the impression cylinder and oscillates
with it, one arın say e³ of the bell crank lever is or may be connected with a lever
acted upon by a cam on the cam shaft (d) of the Machine making one revolution
for each impression, this said cam being shaped to lift the knife bar f and hold it
up until the cam g begins to make the forward movement for making the impression
when the said cam will allow the bar to descend until the arm ex rests upon the
surface of the higher part of the cam g and will then leave it free to act until the
cut is made when the said cam again lifts and holds up the cutting bar f and so
on for each impression.
There is a bar i on each side of the machine, these two bars i being connected
together by a cross rod i¹ to form a frame-Each side bar i of this frame has two
studs and upon each stud there is a bowl i².
The two front bowls run on guide rails 3 secured on the plate e and the two
hind bowls run on the surface of the plate e, so that the frame thus forms a carriage
which can move to and fro.
In the side frames i there are bearings for two rollers and which extend one
over the other across and between the two side frames. These rollers have their
surfaces covered with flannel or other suitable material and they are quite free to
rotate except as hereinafter mentioned-The lower roller is in fixed bearings, but
the bearings of the upper roller i have each a pin to come against them pressed
upon by a spring secured to the side frame and thus the upper roller is pressed
against the lower roller with the sufficient force to give the required grip upon the
paper from the web which passes between them:
On one end of the upper roller ³ (see fig 1) there is a fine toothed ratchet wheel
secured, into the teeth of which a pawl 8 takes, that is jointed upon a stud in a
projection from one of the side bars i of the reciprocating frame or carriage-This
pawl permits the rollers which are geared together to turn to allow the paper to
be drawn through them to the impression cylinder but prevents their rotation thus
causing the rollers to act as grippers in the opposite direction.
On each side of the reciprocating carriage there is a spring bracket i secured,
and another spring ix is secured to the spring bracket. The ends of the lower
bracket carry the ends of a thin lath j extending across and between the brackets 2º,
and the upper spring i* carries an upper lath a little in advance of the
lower one.
Both laths or rods are covered with cloth or other suitable material..
The end of the web of paper is held between these laths j and 1 which serve to
carry and pass it through the opening between the cutting, blades when the upper
blade is lifted from the lower blade, and present it to the grippers c² on the
impression cylinder c. The brackets from the stands e' have bearings for a shaft k
extending across the machine and there are two arms c¹ secured on this shaft k one
on each side each arm connected by a link with the side bars of the frame or
carriage.
On one end of the shaft k there is also an arn 3 connected by a link
end of a lever k having its fulcrum on the side frame A.
with one
having
One arm of this lever is slotted for a stud to be adjusted in it, and upon this
stud a notch can catch which is in a rod jointed to one end of a lever
its fulcrum k* on a stud in the side frame-The lever has a bowl which is kept
against the edge of a cam d on the cam shaft d by a spring d² as shown.
On the side frame there is a bearing for a short shaft
on the end inside the framing and an handle 12 on the
which has an eccentric l¹
end outside the framing.

page_text: By turning this handle into one position the rod or lever 3 is lifted so that its
notch is clear of the stud 7 and by turning into another position (as shown) the
notch can take hold of the stud in the lever /5.
:J.
The cam has to give motion to the reciprocating carriage to bring the
laths j and j' carried by the springs and ix back into about the position in which
they are shown in the figures (when one or two inches in length of the web will
project in front of them) and then push the carriage forward, the laths passing
between the open cutting blades until the end of the web is brought within the
grippers c² and hold it there for an instant until the grippers close upon it, then
the reciprocating carriage is drawn back to the first position.
The roll or web of paper is on a drum or bobbin m having its spindle-pivots in
brackets from the framing in which it is free to rotate The paper passes from the
roll, descends and passes under a small compensating roller. m and then ascends and
passes over the surface of the roll, then under a smoothing bar m² on the table then
between the small rollers and 25, then between the nipper laths j and j', (which
only put a slight friction upon it) and then to the grippers when the reciprocating
carriage moves towards, them.
There is a ratchet wheel-m³ secured on the end of the axis of the spindle of the
web bobbin and a lever m' is free to oscillate upon it which lever has a pawl jointed
to it to work on the teeth of the ratchet m³. The lever m' is slotted to allow a stud
to be adjusted as required at a greater or less distance from the fulcrum or axis,
and the pin in this slotted lever m¹ is jointed. with the end of the lever 15, so that
at each forward movement of the reciprocating carriage the bobbin receives motion
to start the unrolling of the web, and the extent of this movement may be increased
or decreased by the adjustable stud.
The small roller m¹ is suspended in the loop formed by the paper and compensates
and gives way to sudden or excessive strains rising and falling in the slotted guiding
brackets m³ secured to the floor, one on each side, and allows time for the inertia of
the bobbin to be overcome at the beginning of each impression.
It will be seen that though the lever m³ starts or helps to start the rotation of
the bobbin m the ratchet m³ allows the latter freedom to rotate forward after the
movement given to it by the ratchet in the same direction has ceased.
The parts n are two guides adjustable on the table to come against the edges of
and keep the paper in the required central position.
The bar m² is of wood or other material its underside faced with cloth or other
suitable material-Thère is a pin in each end of the bar which passes through a hole
in a bracket mo at each side secured to the table, and is thus prevented from,
passing along with the paper upon which it simply rests.
Having now particularly described and ascertained the nature of our said.
invention and in what manner the same, is to be performed We declare that
what we claim is
1. In printing machines with reciprocating type or other printing surfaces the
system or mode of or entering the end of the web to be printed within grippers which
then grip and draw the paper or material from the web or roll through or between
cutters or perforators which are allowed to act by a cam when the grippers have
advanced to the required extent, to cut, perforate or sever the paper or material as:
it is passing, substantially as herein before described.
2. In printing machines with reciprocating type or other printing surfaces, the
system or mode of entering the end of a web to be printed to within the grippers
of an impression cylinder which will then grip and draw the paper or material from
the roll through or between shears or their equivalents, which material while in
motion and receiving the impression is cut or severed by the action or permission of
a camion or geared up with the impression cylinder, substantially as herein before
described.
3. In printing machines the system or mode of feeding and entering the end of a
web to be printed into the grippers of the impression cylinder by gripping rollers or

page_text: their equivalents on a reciprocating or oscillating carriage or frame, which, gripping
rollers or their equivalents permit the web to be drawn through them by the
grippers on the impression cylinder until severed from the web, substantially as
herein before described.
4. In printing machines having reciprocating type or other printing surfaces the
combination and arrangement of the mechanism for feeding from a web and cutting
off, substantially as hereinbefore described and illustrated by the drawings.
