IMPROVEMENTS IN PRINTING MACHINES AND IN APPARATUS PROVISIONAL SPECIFICATION
Year: 1874

page_text: LETTERS PATENT to Edward Edwards Colley, of No. 1, West End,
Doddington Grove, Kennington Park, in the County of Surrey, for
the Invention of "IMPROVEMENTS IN PRINTING MACHINES AND IN APPARATUS
PROVISIONAL SPECIFICATION left by the said Edward Edwards Colley
at the Office of the Commissioners of Patents, with his Petition,
on the 5th November 1874.
I, EDWARD EDWARDS COLLEY, of No. 1, West End, Doddington
Grove, Kennington Park, in the County of Surrey, do hereby declare
the nature of the said Invention for "IMPROVEMENTS IN PRINTING
MACHINES AND IN APPARATUS FOR PREPARING PAPER FOR PRINTING," to be as
follows:-
-
This Invention has for its object improvements in printing machines
and in apparatus for preparing paper for printing.
In machines for the rapid printing of newspapers the paper is now
commonly brought to the printing machine in a continuous roll, and

page_text: after it has been printed on both sides by cylinders with stereotype plates
mounted upon them it is cut up into sheets and delivered.
Now in order to cut up and deliver the continuous printed paper I
employ the following means:-The continuous printed sheet, which is of
the width of two newspapers, is passed down between a pair of cutting |
rollers, but before it reaches the nip of these rollers it is divided longi-
tudinally by a circular saw-like blade, the edge of which enters a groove
in the upper cutting roller. The transverse division of the paper is
effected by two cutting blades on the lower roller, which are caused to
slide in and out radially by cams and springs. Each blade as it comes
up to the nip of the cutting rollers is projected outwards, and enters a
groove in the roller above, so severing the paper which is between the
rollers.
The paper after it has been divided passes down, resting on the surface
of the lower cutting roller until it is taken by spring grippers on the 1
surface of a delivering drum, which revolves in contact with the lower
cutting roller and at the same surface speed.
As the grippers on the delivering drum approach the cutting roller
they are opened by arms on their axes coming into contact with
stationary cam surfaces.
The surface of the cutting roller is recessed to allow the open grippers
to pass and insert their ends beneath the sheets of paper, and then as the
grippers recede from the cutting roller they close by the action of their
springs upon the edges of the sheets and take them on to the surface of
the delivering drum. This drum is composed of hoops mounted on an 2
.axis and carrying the grippers, and between the hoops, beaters, or "fly
rods are mounted. They are carried upon an axis and receive a vibratory
motion from a cam. As the delivering drum carries the sheets round,
and when they are on the under side of the drum the fly rods strike
them from within and in a downward direction. Fixed cam surfaces
cause the grippers holding the sheets to open immediately afterwards,
and so the sheets are released and landed on the pile.
"
In order to prepare the paper for printing it is unwound from the roll
on which it comes from the paper mill and rewound upon a wooden
roller, and in its passage from roll to roll it is moistened with water.
The wooden roller to wind the paper upon is supported between two
horizontal cylinders fincly fluted from end to end. These two cylinders

page_text: are driven by a tooth wheel geared into a wheel fixed on the end of each
cylinder spindle. The centre wheel is given motion to in the usual way
by fast and loose pulleys. The paper passes over the first cylinder,
which is wetted by a piece of blanket fastened to a plate of iron and
dipping into a water tank. The blanket presses tightly against the
cylinder and fills each fine groove with water, which is absorbed by the
paper travelling with the drum. The roller resting on the grooved
cylinders is rotated by them at a constant surface speed, whilst it increases
in bulk from the accumulation of the paper around it. The ends of the
wooden roller are received into vertical guides, and the rotation of the
roll from which the paper is drawn is checked by friction.
SPECIFICATION in pursuance of the conditions of the Letters Patent
filed by the said Edward Edwards Colley in the Great Seal Patent
Office on the 5th May 1875.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, EDWARD
EDWARDS COLLEY, of No. 1, West End, Doddington Grove, Kennington
Park, in the County of Surrey, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Fifth day of November, in the
year of our Lord One thousand eight hundred and seventy-four, in the
thirty-eighth year of Her reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto me, the said Edward Edwards Colley, Her
special license that I, the said Edward Edwards Colley, my executors,
administrators, and assigns, or such others as I, the said Edward Edwards
Colley, my executors, administrators, and assigns, should at any time
agree with, and no others, from time to time and at all times there-
after 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 PRINTING MACHINES AND IN APPARATUS FOR PREPARING
PAPER FOR PRINTING," upon the condition (amongst others) that I, the said
Edward Edwards Colley, 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

page_text: 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 Edward Edwards Colley, 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 thereof, that is to say :-
-
This Invention has for its object improvements in printing machines
and in apparatus for preparing paper for printing.
In machines for the rapid printing of newspapers the paper is now
commonly brought to the printing machine in a continuous roll, and
after it has been printed on both sides by cylinders with stereotype plates
mounted upon them it is cut up into sheets and delivered.
Now in order to cut up and deliver the conținuous printed paper I
employ the following means:-The continuous printed sheet when of
the width of two newspapers is passed down between a pair of cutting
rollers, but before it reaches the nip of these rollers it is cut or divided
longitudinally by a circular saw-like blade, the edge of which enters a
groove in the upper cutting roller. The transverse division or cutting of
the paper is effected by a cutting blade on the lower roller, which is
caused to slide in and out radially by cams. The blade as it comes up
to the nip of the cutting rollers is projected outwards, and enters a
groove in the roller above, so severing the paper which is between the
rollers.
The paper after it has been cut or divided passes down, resting on the
surface of the lower cutting roller until it is taken by spring grippers on
the surface of a delivering drum, which revolves in contact with the
lower cutting roller and at the same surface speed.
As the grippers on the delivering drum approach the cutting roller
they are opened by arms on their axes coming into contact with
stationary cam surfaces.
to
The surface of the cutting roller is recessed to allow the open grippers
pass
and insert their ends beneath the sheets of paper, and then as
the grippers recede from the cutting roller they close by the action of
their springs upon the edges of the sheets and take them on to the surface
of the delivering drum. This drum is composed of hoops mounted on

page_text: "
an axis and carrying the grippers, and between the hoops beaters or "fly
rods are mounted. They are carried upon an axis and receive a
vibratory motion from a cam. As the delivering drum carries the sheets
round and when they are on the under side of the drum the fly rods
strike them from within and in a downward direction. Fixed cam
surfaces cause the grippers holding the sheets to open immediately
afterwards, and so the sheets are released and landed on the pile.
In order to prepare the paper for printing it is unwound from the roll
on which it comes from the paper mill and rewound upon another roller,
and in its passage from roll to roll it is moistened with water.
The roller to wind the paper upon is supported between two horizontal
cylinders finely fluted from end to end. These two cylinders are driven
by a tooth wheel geared into a wheel fixed on the end of each cylinder
spindle. The centre wheel is given motion to in the usual way by fast
and loose pulleys. The paper passes over the first cylinder, which is
wetted by a piece of blanket fastened to a plate of iron and dipping into
a water tank. The blanket presses tightly against the cylinder and fills
each fine groove with water, which is absorbed by the paper travelling
with the drum. The roller resting on the horizontal grooved cylinders is
rotated by them at a constant surface speed, whilst it increases in bulk
from the accumulation of the paper around it. The ends of the roller
are received into vertical guides and the rotation of the roll, from which
the
paper is drawn is checked by friction.

page_text: are the distributing rollers; g, g', are the inking rollers which receive
the ink from the distributing cylinders e, e¹, and apply it to the stereo-
type plates fixed upon the type cylinders h, h².
เ
The paper from the reel a first passes between the impression cylinder i
and the type cylinder h, and is so printed on one side. The paper is
delivered from the first impression cylinder i to the second impression
cylinder with the printed face of the paper against the surface of
the cylinder. The blanket around this cylinder is so arranged, as the
Drawings show, that when it becomes soiled to an extent to blur the
printed paper the blanket surface can be changed without difficulty.
The cylinder k also runs in contact with a blanket covered cylinder / to
which is transferred much of the ink which the cylinder k receives from
the printed paper. The blanket surface on the cylinder can also be
readily changed from time to time. The paper descends between the
cylinder / and the type cylinder h³, and is so printed on the second side.
It then passes between the conducting roller m and the upper cutting
cylinder n. The roller m has upon it a circular knife m¹ with saw like
teeth, which divide the sheet of paper longitudinally, provided as I
prefer where very large numbers are to be thrown off, that the machine
be made of double width. The transverse cutting takes place at the
nip of the two cutting cylinders n and o. A section of these cylinders
is shown at Figure 3, and a front view of the cylinder o which carries
the knife is shown at Figure 4. o¹ is the knife; it is attached to a bar o³,
which is arranged so that it can slide to and fro in a radial slot in the
cylinder. The blade o² has not a straight edge, but the edge is saw like
or rather is provided with a number of lancet-like points which penetrate
and divide the paper. The blade of the knife is held between two
wooden bars o³, o³, forming a sheath. The ends of the knife bar o* enter
into fixed cam grooves p, shown separately at Figures 5, which throw
the knife forward and cause it to divide the paper when the sheath o³ is
in contact with the wooden pad n¹ upon the roller n. The pad, as the
Drawings show, has a groove in it to receive the edge of the knife.
The wooden sheath o' has in it recesses o³*; these are to admit of the
opening of the grippers p* on the skeleton delivery drum p**. This
drum, as is more clearly seen at Figure 6, consists of a convenient
number of hoops, which can be set at convenient distances apart upon
their axis. If the machine be double width more hoops than the
Drawings show will be necessary. Each hoop carries three or it might
•

page_text: be other number of grippers, which are held closed by springs, but are
opened as they pass the cutting roller o by fixed stops or cam surfaces q, q.
An arm p² on the gripper axis comes against the cam piece q and throws
the grippers on this axis open, and when the cam piece is passed the
grippers are closed by the spring and made to catch the end of the paper
which has just been cut by the cutting apparatus. The cam pieces q, Q,
are clamped in suitable positions upon the fixed rod 1. The cam pieces q
are shown separately at Figures 7; 8, 8, are other cams, which in a
similar manner open the grippers to deliver the paper when it has been
brought to a suitable position; they are similarly clamped upon a rod t
and are shown separately at Figure 8; u is an axis carrying a number
of wooden rods '; a side view of one of them is shown at Figure 9; they
descend upon the sheets of paper brought round by the drum p** at
the moment when the grippers arc on the point of opening and they
deposit the sheet on the board v. The axis u takes its motion from
cams to on the axis of the roller o; the cams give motion to levers x,
which by connecting rods y are linked with arms on the axis u.
Figure 10 is a side view of the apparatus which I employ to prepare
the paper for printing; Figure 11 is a front elevation of the same.
a, a, is the frame; on it are the bearings for the axis 6 of the reel on
which the paper comes from the paper mill. A brake lever and weight,
shown in the Drawings, prevent the reel from rotating too easily; c, c¹,
are two grooved metal rollers; they are driven in the same direction and
at the same surface speed. The grooves run longitudinally of the rollers,
and are fine and shallow. The roller c dips into a trough & containing
water; e is a pad of woollen cloth, which absorbs the water and supplies
it to the grooves of the roller. The paper is drawn from the mill reel
and passing in contact with the surface of the roller c takes the moisture
from it. The moistened paper is then wound upon the core f, which
as the paper accumulates upon it is able to rise between the standards
a', a', of the frame a, but the core f is pressed down constantly by the
levers (one on either side),.which have weights g¹ at their ends. The
roll of paper being driven by surface contact with the rollers c, which
rotate uniformly, the speed at which the paper is wound up will be
constant whilst the roll increases in size; this could not well be the case
if the roll were driven by its core.
A plan of a portion of the water trough d is shown at Figure 12.
Sometimes I employ the damping machine to supply the paper direct
