Improvements in Reciprocating or Traveling Cylinder Web
Printing Machines.
I, GEORGE CROYDON MARKS, of 18, Southampton Buildings, Chancery Lane, in the
County of London, Engineer, (which has been communicated to me by Henry
Alexander Wise Wood, of 1, Madison Avenue, City, County, and State of New York,
United States of America, Engineer,) do hereby declare the nature of this invention to
be as follows:-
The object of this invention is to improve the reciprocating or traveling cylinder
web printing machine.
The invention consists of three improvements in such machine.
The first relates to an improved mechanism for manipulating the web in the
machine.
The second relates to an improved means for associating the product of the machine
so that various size and paged papers can be produced.
The third improvement relates to an improved means for feeding in the web so
that the same can be readily spliced in case of breakage.
The reciprocating cylinder web printing press, as used to-day, consists of a bed on
which the type is placed, a cylinder which is reciprocated to roll thereover, guides
for the web so arranged that the cylinder will move in a moving fold of the web, and
a web-manipulating device.
These devices in all forms of reciprocating cylinder presses are arranged so that
the web above the bed, and to some length beyond the ends of the same, is held
stationary during the printing, and is pulled or shifted forward during the non-
printing or non-impression period.
This description applies to a single bed press, that is a press employing one
stationary bed and one traveling cylinder arranged to print on but one side of the
web.
The same construction is also used in reciprocating cylinder printing machines in
which the web is twice printed or perfected, in this form of machine, two beds and
two cylinders being used, and the web throughout the machine being held stationary
during the time of the printing, and shifted or pulled forward during the non-
printing period.
It has been found in operating this class of presses that the limit of speed and
therefore the limit of usefulness of this class of machines is the rate at which the
web can be shifted throughout the machine around the surfaces of the impression
cylinder or cylinders and the various guides.
As the web necessarily stretching through this part of the machine is of long
length, it will be seen that this length of web is intermittently put under great
strain, owing to the intermittent pull necessary to intermittently shift a long length
of web around a large number of surfaces.
It has been found that the cylinders and apparatus can be operated at a much
faster speed than the web can be intermittently shifted.

page_text: The ideal way to manipulate a web in a printing machine is to run the same
continuously throughout the entire mechanism, as, by this means, the web can be
run through the machine with very little strain, as every guide around which the
same passes can be rotated at the proper speed to help the web along, and a web
running continuously will stay accurately in position.
To run all the web continuously is impossible with a printing press in which a
stationary form is used, as it is necessary to hold the web stationary longitudinally
relatively to the form, during the time of impression, and to shift the same
during the non-impression period.
The object of the first improvement is to bring the reciprocating cylinder web
printing press more nearly and more closely to have a continuous movement of
the web.
To do this, the looping or shifting device is arranged to move with the cylinder or
cylinders.
By this construction, the web can be run continuously at all points except the
small section or sections of web directly around the cylinder or cylinders.
The preferred means for accomplishing this desirable result consists in arranging
loopers at each side of the cylinder or cylinders in the carriers, so that said loopers
will travel with the cylinder, and so that said loopers will move up and down to give
the proper conditions to the web.
These loopers moving back and forth with the cylinder or cylinders are operated
by any desired mechanism, as, for example, by a cam-actuated, oscillating shaft,
a sleeve sliding on said shaft and carried in bearings projecting from one carrier,
and connections from the sleeve to the loopers.
The loopers at the sides of each cylinder are generally mounted in arms
projecting from a shaft, which shaft is journalled in the carriers.
By this construction, the web can run continuously from the feeding-in device
to the looper at one side of the first impression cylinder, continuously from the
looper at the other side of the first impression cylinder to the looper at one side
of the second impression cylinder, and continuously from the looper at the other
side of the second impression cylinder to the feeding-out device.
This way of handling the web results in a great improvement, as the only
portions of the web that have to be given the intermittent movement are the sections
that lie directly around the surface of the impression cylinder.
These small portions of the web necessarily have to be shifted intermittently, and
during impression kept in harmony with the periphery of the cylinder or
cylinders.
It will also be seen that, by shifting only these small sections of web intermittently,
a very slight strain is put upon the web, as each of these sections of web has to be
slipped over but one surface, and that the remaining web in the machine, moving
continuously, will run very accurately and nicely around its various guides.
This improvement greatly and very materially increases the speed of reciprocating
cylinder web presses, and also the accuracy and nicety with which printing can be
effected.
Of course the improvement is applicable to either a single form of such machine,
in which the web is printed upon but one side, or to a double form of such machine
in which the web is printed upon both sides.
The second improvement relates to an improved means for associating the
product.
This consists of a double turner-bar arranged in connection with another turner-
bar and rolls parallel to the main movement of the web, so that a different width of
newspaper can be produced, as, for example, a newspaper six or seven columns wide
can be produced, as desired.
A still further carrying out of this improvement consists in providing an
additional turner-bar and roll, so that a four, six, eight or ten-page paper can be
produced.
The third improvement consists in providing, in addition to the usual mechanism

page_text: used in printing presses, by which the press can be run at full speed or at a slow
speed, an auxiliary means, so that only the feeding-in drum can be run at a slow
speed.
This is done by driving the press at the slow speed through a pawl-and-ratchet
wheel, and in providing the feeding-in drum with an additional pawl-and-ratchet
mechanism, so that, by disengaging one pawl-and-ratchet mechanism, the feeding-in
drum alone will be turned at a slow speed.
This is an advantageous consiruction in case of breakage of the web.
The breakage of the web in a machine of the class referred to generally occurs in
some part of the printing mechanism.
By quickly stopping the machine, and then driving the feeding-in drum only, the
incoming web can be advanced so that the end of the incoming web can be pasted or
secured to the broken end of the web, and then the machine started slowly, so that
the new end of the web will be drawn through the associating mechanism, without
the necessity of re-threading these parts.
This mechanism enables the press to be much more quickly started, in case of
breakage, than where, as with the presses ordinarily built, the machine has to be
entirely re-threaded..
The feeding-in drum is also preferably driven at its full speed as well as at a slow
speed through a pawl-and-ratchet mechanism, so that at every operation the
feeding-in drum is free to turn forward.
This is advantageous in that it is generally the custom in this class of machines
to make the tension of the feeding-out devices adjustable, so that, under different
conditions, the feeding-out device may demand a little more web than can be
supplied by the feeding-in device.
When this takes place in the old constructions, the feeding-in device cannot
supply the extra web sometimes required, and therefore the web in the press will be
put under tension and broken.
However, if the above construction is used by which the feeding-in device is driven
under every condition through a pawl-and-ratchet mechanism, if an abnormal tension
should be put upon the web in the machine from the feeding-out device, the
feeding-in drum can turn slightly forward through its ratchet mechanisin, and thus
the additional web sometimes required by the feeding-out device can be supplied
without breaking.

Improvements in Reciprocating or Traveling Cylinder Web
Printing Machines.
I, GEORGE CROYDON MARKS, of 18, Southampton Buildings, Chancery Lane,
London, W.C., Consulting Engineer, (being a communication from Henry Alexander
Wise Wood, of 1, Madison Avenue, City, County, and State of New York, Engineer,)
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 :-
The object of this invention is to improve the reciprocating or traveling cylinder
weh printing machine.

page_text: The invention consists of three improvements, which may be applied to such
machine, although some of the improvements, as hereafter specified, are capable of
general application.
The first improvement relates to an improved mechanism for manipulating the web
in the machine.
The second relates to an improved means for associating the product of the
machine, so that various sized and paged papers can be produced..
The third improvement relates to an improved driving and feeding mechanism, so
arranged that the machine can be readily driven, and so that the web can be readily
spliced in case of breakage.

Fig. 23 is a plan of the gearing forming the same,
Fig. 24 is a detail of part of the gearing, and
Fig. 25 is a sectional diagramatic elevation of the gearing.
The reciprocating cylinder web printing press, as used to-day, consists of a bed on
which the type is placed, a cylinder which is reciprocated to roll thereover, guides
for the web so arranged that the cylinder will move in a moving fold of the web, and
a web-manipulating device.
These devices in all forms of reciprocating cylinder presses are so arranged that the
web above the bed, and to some length beyond the ends of the same is held stationary
relatively to the bed during the printing, and is pulled or shifted forward during the
non-printing or non-impression period.
This description applies to a single bed press, that is a press employing one bed
and one traveling cylinder arranged to print on but one side of the web.
The same construction is also used in reciprocating cylinder printing machines in
which the web is twice printed or perfected, in this form of machine, two beds and
two cylinders being used, and the web throughout the machine being shifted or
pulled forward during the non-printing period.
It has been found in operating this class of presses, that the limit of speed, and
therefore the limit of usefulness of this class of machines, is the rate at which the

page_text: web can be shifted throughout the machine around the surfaces of the impression
cylinder or cylinders and the various guides.
As the web necessarily stretching through this part of the machine is of long
length, it will be seen that this length of web is intermittently put under great
strain owing to the intermittent pull necessary to intermittently shift a long length
of web around a large number of surfaces.
It has been found that the cylinders and apparatus can be operated at a much
faster speed than the web can be intermittently shifted.
The ideal way to manipulate a web in a printing machine, is to run the same con-
tinuously throughout the entire mechanism, as thereby the web can be run through
the machine with very little strain, as every guide around which the same passes can
be rotated at the proper speed to help the web along, and as a web running
continuously will stay accurately in position.
To run all the web continuously is impossible with a printing press in which a
flat form is used, as it is necessary to hold the web stationary longitudinally rela-
tively to the form during the time of impression, and to shift the same during the
non-impression period.
The aim of the first part of this invention is to bring the reciprocating cylinder
web printing press more nearly and more closely, to have a continuous movement
of the web.
I have discovered that by moving the manipulating or shifting devices with the
cylinder or cylinders, nearly all the web in the printing machine can be run con-
tinuously, and only a small section or sections of the web directly around the
cylinder or cylinders need be shifted intermittently, and this arrangement con-
stitutes the present invention.
This new manipulation results in a great improvement in the way of handling a
web in a press of this character, as, by this construction, the web can run con-
tinuously from the feeding-in device to the first cylinder, continuously from the
first impression cylinder to the second impression cylinder, and continuously from
the second impression cylinder to the feeding-out device, and the only portions of
the web that have to be given an intermittent movement are the sections which lie
directly around the surface of the impression cylinder or cylinders.
These small portions of the web necessarily have to be shifted intermittently,
and during impression kept in harmony with the periphery of the cylinder or
cylinders.
It will also be seen that by shifting only the small sections of web inter-
mittently, a very slight strain is put upon the web, as each of these sections of web
is of short length, and has to be slipped over but one surface, and that the remaining
web in the machine, moving continuously, will run very accurately and nicely
around its various guides.
Of course my invention is applicable to either a single form of such machine in
which the web is printed upon but one side, or to a double form of such machine
in which the web is printed upon both sides.
I will now describe the best mode now known to me for applying the principle of
my invention, and reference to follow this description should be had to the first three
sheets of the drawings, in which I have shown a well known form of reciprocating
cylinder web perfecting printing press with my improvements applied thereto.
Referring to the drawings and in detail, 20 and 21 represent the side frames,
between which are arranged the form beds A and B.
C, C designate the cylinder carriers, which are fitted to slide in ways on the side
frames, and these carriers are arranged to carry the cylinders and the various parts
hereinafter referred to.
The cylinders have gears arranged on the ends thereof, which mesh with racks
carried by the beds, as indicated in dotted lines in Fig. 3, so that, as the impression
cylinders are reciprocated over the forms, they will rotate, so that there will be no
slip between the periphery of the impression cylinders and the forms.

page_text: Form rollers F, F are arranged at each side of each cylinder to properly ink the
forms placed on the beds, and co-operating with each set of form rollers are dis-
tributers and conveying rollers F1, F2, which are arranged to take ink from ink-
fountains E arranged at each end of each bed.
The web w is drawn from a web-roll W, which may be placed in suitable brackets
at the end of the machine, and is led around guides 22 and 23 to the feeding-in
drum 24, which is continuously driven.
Co-acting with the drum 24 is a set of tapes 25 which pass around suitable tape-
pulleys or rolls 26, 27 and 28.
By this construction, the web will be continuously drawn from the web-roll and
continuously paid into the machine.
The web then passes to a roller or guide 29 mounted in the carriers, then up
around a looper-roll 30, down around the first impression cylinder 31, up around
another looper-roller 32, and then around a guide 33 also carried by the carriers.
From the guide or roller 33, the web is led around an adjustable register roll 34,
up around a roller 35; and these rollers 34 and 35 may be continuously driven by
any of the usual belting mechanism, so that the web will continuously run around
the same.
From the roller 35, the web is led to a guide 36 mounted in the carriers, up
around a looping roller 37, down around the second impression cylinder 38, up
around another looping-roller 39, and then around a guide 40, the parts 36 and 40
inclusive being mounted in the carriers.
From the roll 40, the web is led to a guide 41, and then to a continuously turning
feeding out drum 42, co-acting with which is a set of tapes 43, which turn around
tape pulleys 44, 45 and 46.
From the continuously running, feeding-out device, the web may be slit into sec-
tions, the sections associated by suitable turners G, and the associated webs led to
any suitable form of folding device the details of which are not necessary to describe
in this application.
The operating and driving mechanisin for these parts may be arranged as follows:-
50 designates a shaft, from which power may be applied to the machine.
On this shaft is arranged a bevel-pinion, which meshes with and engages a large
bevel driving-gear 52, which is mounted on the end of the vertical shaft 53, which
is stepped in suitable bearings, as shown.
The bevel-gear 52 carries a crank-pin 54, which carries a suitable block, which
engages a slotted yoke 55, which connects the two carriers, the yoke passing through
slots cut in the side-frames of the machine, as indicated.
Also mounted on the shaft 50 is a pinion 56, which meshes with an intermediate 57,
which intermediate drives a gear 58 secured upon the shaft 59 of the feeding-in
drum 24, as indicated in dotted lines in Fig. 1.
This gear is so proportioned that the feeding-in drum will feed forward a length of
web equal to two sheets during each forward and backward reciprocation of the
carriers.
Also engaging the pinion 56 is an intermediate gear 60, which drives a shaft 61,
which I term a 66 can shaft."
From the cam shaft, the feeding-out drum 42, the guide 41 and the various rollers
over which the web or sections of web pass, are driven by gearing, as indicated by
dotted lines in Fig. 1.
The cam shaft 61 is so geared that it will make two turns for each reciprocation of
the carriers.
Arranged on the cam shaft 61 is a screw-cam 62.
63 designates a pipe-shaft (which form is adopted for purposes of rigidity), which
extends parallel to the movement of the carriers, and which is journalled in brackets 64
and 65, secured to the side frame 20.
On the end of this shaft 63 is secured an arın 66, which has a roller 67 engaging
the screw cam 62.
Extending from the rear carrier C are brackets 68 and 69, between which is fitted a

page_text: key-way cut in the pipe-shaft 63.
By this construction, as the carriers are reciprocated, the bush 70 will be moved
back and forth on the pipe-shaft, but, as the pipe-shaft is oscillated, the bush will also
be oscillated.
Extending from the bush 70 is an arm 71, which connects by link 72 to an arm 73,
mounted on a shaft 74, which shaft is journalled in the carriers above the first
impression cylinder 31.
Mounted on this shaft 74 are walking-beam arms 75, in which the looping rollers 30
and 32 are journalled.
Also extending from the bush 70 is an arm 76 which connects by link 77 to an
arm 78 fitted on a shaft 79, which is journalled in the carriers above the second
impression cylinder 38, and which carries walking-beam arms 80, in which the looping
rollers 37 and 38 are journalled.
By this means, the said looping rollers 30 and 32 and 37 and 39 will be oscillated
from the cam 62 independently of the reciprocation of the cylinders.
The detail operation of this mechanism will be described after describing the opera-
tion of the single-bed machine.
There are many other forms of gearing which may be used to actuate the loopers
carried by the carriers, one such modified form being shown in Fig. 5.
In this figure, a miter-gear 81 is arranged on the shaft of the feeding-in drum,
and, by means of this miter and miters 82, 83 and 84, drives a slotted shaft 85, which
is journalled in suitable bearings on the rear side frame.
The feeding-out drum may also be driven, if so desired, from the slotted shaft 85,
by means of suitable miters, as shown.
The slotted shaft 85 passes through suitable brackets 86 and 87 projecting from
the rear carrier C, and fitted in these brackets is a cam 88, which has a key which
engages the slotted shaft 85, as shown in detail in Figs. 7, 8 and 9. One or two cains
may be used.
In Fig. 5 a single cam is shown, engaging which is a roller 89 mounted on an
arm 90 projecting from the shaft 74, and which arm connects by link 91, bell-crank
lever 92 and link 93 to one of the walking-beain arms 80.
In Fig. 6, two cams 88 are shown, the second cam engaging a roller projecting
from the bell-crank lever 92, and the link 91 being dispensed with.
With both these constructions, the loopers carried by the carriers will be properly
actuated.
In. Figs. 10 and 11 I have shown a single-bed machine to illustrate the simplest
application of my invention.
In this machine there is shown a single bed A, co-acting with which is an impres-
sion cylinder 31 mounted in carriers C, which are reciprocated by any mechanism not
necessary to detail.
The feeding-in and feeding-out drums 24 and 42 are arranged as shown.
94 desiguates a shaft, which is driven from any suitable part of the machine, and
from which, by suitable gearing, as indicated, the feeding-in and feeding-out drums
are continuously rotated.
On the end of the shaft 94 is arranged a cam 95, engaging which is a roller 96
carried by yoke 97, which is connected to an arın 98 secured on the end of a slotted
shaft 99.
Sliding on this shaft 99 is a bevel-gear 100, which has a key to engage the
shaft 99, and which is fitted in a bracket formed with or projecting from one
carrier C.
This bevel-gear engages a bevel-gear 101 on the shaft 74, the other parts numbered
being substantially the same as in the previous construction.
Referring now to the diagrams shown in the sixth sheet of the drawings, I will first
describe the operation of my improved device as applied to the single-bed machine.
Further, suppose that the length of the sheet it is desired to manipulate with the
margins is twenty-four inches, and that impression is to exist for a quarter revolution

page_text: of the driving mechanism, or that the periods of impression and non-impression are
to be equal in point of time.
With this assumed proportion, the feeding-in and feeding-out drums will be so
turned that forty-eight inches of web will be continuously paid in and paid out of the
machine during a complete forward and backward reciprocation of the carriers.
Referring now to the diagrams, it will be seen that the reciprocation of the
impression cylinder, the loopers and guides mounted in the carriers does not affect
the longitudinal position of the web.
This can be readily understood by imagining that the web was held stationary
between the feeding-in and feeding-out drum, and that the cylinder and the guides
and loopers are reciprocated back and forth over the bed.
This will not affect the longitudinal position of the web.
With the particular proportion above assumed, the cam which is to operate the
loopers, turning twice for each forward and backward reciprocation, resolves itself into
substantially a heart-shaped cam.
Starting first with the impression cylinder in the position shown in Fig. 13, as just
commencing its printing movement to the right, and suppose that it moves to the
position shown in Fig. 14.
During this movement, a quarter revolution of the driving mechanism takes place,
so that twelve inches of web will be paid in by the feeding-in drum 24, and twelve
inches of web will be drawn out by the feeding-out drum 42.
The twelve inches of web paid in by the feeding-in drum will be taken up by the
looper 30 rising from the position shown in Fig. 13 to the position shown in Fig. 14;
and the twelve inches of web required by the feeding-out drum 42 will be supplied
by the looper 32 descending to the position shown in Fig. 14.
This movement of the loopers will keep the section of the web between the same
around the impression cylinder in harmony with the impression cylinder during
impression, the result being that the web will run continuously from the feeding-in
device to the first looper 30, and continuously from the feeding-out looper 32 to the
feeding-out device, without affecting the section of web about the impression cylinder
or its presentation to the forin.
Now then, suppose that the impression cylinder passes off the form to its extreme
right-hand position, as shown in Fig. 15, and back to the position shown in Fig. 16,
or in other words, that the impression cylinder reverses its movement off the form,
which, under the assumed proportions, occupies a quarter rotation of the driving
gear.
During this movement of the cylinder from the position shown in Fig. 14 to the
position shown in Fig. 16, the cam that operates the loopers will make a half revolu-
tion, and will restore the loopers to the position shown in Fig. 13, but, during this
movement, twelve inches of web will be paid into the machine by the feeding-in
drum, and twelve inches of web will be paid out of the machine by the feeding out
drum, and during this reversal, the looper 32 will rise from the position shown in
Fig. 14 to the position shown in Fig. 16, and the looper 30 will oppositely move.
This movement of the loopers will cause a shift of twelve inches of web about the
surface of the impression cylinder, which, added to the twelve inches of forward move-
ment imparted to the web by the feeding-out drum will make a total shift of web
about the surface of the impression cylinder equal to twenty-four inches, or the length
of the sheet.
During the next impression period, as the cylinder moves to the left, that is, from
the position shown in Fig. 16 to the position shown in Fig. 17, the loopers will act to
hold the section of web about the periphery of the impression cylinder in harmony
therewith, as above described in the movement from Fig. 13 to Fig. 14.
As the cylinder reverses at its left-hand extreme, that is, as it passes from the
position shown in Fig. 17 to its extreme left-hand position, shown in Fig. 12 back to
the position shown in Fig. 13, the loopers will again act to shift or respace the web.
In other words, the loopers are so timed as, during impression, to act in opposition
to the feeding-in and feeding-out devices, to nullify the movement thereof, so that

page_text: the section of web about the periphery of the impression cylinder will remain in
harmony therewith during impression, and to act during the non-impression period
in conjunction with the feeding-in and feeding-out devices to give a shift of web
about the periphery of the impression cylinder of the amount of web fed in during the
impression periods, together with the amount of web stored by the loopers during the
non-impression periods.
This is a most advantageous construction, as all the web that is possible moves
continuously, and at a uniform speed; that is, the web runs continuously from the
feeding-in drum to the looper 30, and continuously from the feeding-out looper 32 to
the feeding-out drum 42 during the entire operation, so that the only section of web
which has to be given an intermittent movement or slip is the small section of web
extending about the periphery of the cylinder 31 between the loopers 30 and 32.
The action of the preferred form of machine shown in the first four sheets of the
drawings is like that described in connection with the diagrams, except that, as the
web is led in opposite directions about the two impression cylinders, the loopers 30
and 39 and 32 and 37 will have to move oppositely, which is done by the con-
nections before described.
In the perfecting form of the device, it will be seen that the web moves
continuously at all times from the web-roll to the looper 30, continuously from
the looper 32 to the looper 37, and continuously from the looper 39 to the
feeding-out device, and that the only portions of web which have to be intermittently
shifted are those small sections of web lying around the peripheries of the two
impression cylinders and controlled by the loopers.
It is a most advantageous point to keep the web between the two cylinders; that
is, the web extending from the looper 32 around the looper 37 moving continuously,
as this is the longest run of web in the ordinary form of machine that has to be
intermittently moved.
By moving this portion of the web continuously, the same will nicely run and
keep in position on the rollers 34 and 35, which, as before described, may be con-
tinuously driven by any suitable mechanism.
In some instances I contemplate arranging cam-brackets on each of the side
frames, so that the loopers will be driven from both sides, although, in most cases,
it is enough to rigidly secure the arms which carry the loopers on the shafts which
are journalled in the cylinder carriers, and to operate them from but one side.
It is within the scope of my invention to lead the web directly from the impression
cylinder 31 around the guide 33 without passing around the looper 32, and then
directly from the looper 36 to the impression cylinder 38 without passing around
the looper 37.
With this way of leading the web through the press, the web will run continuously
from the feeding-in device to the looper 30, and continuously from the looper 39 to
the feeding-out device; but the loop of web between the two impression cylinders
will be moved intermittently.
While this arrangement is within the scope of my invention, the previous con-
struction is very much preferred for reasons before stated.
Other inanipulating devices besides loopers may be arranged to move with the
impression cylinder or cylinders, to take up or pay out the web to get the results
before described.
My invention is applicable of course to machines which have other proportions
between the impression and non-impression periods, and which manipulate other
lengths of sheets, and which have other arrangements of beds and carriages and of
the various parts, the particular forms chosen being those which can be shown to
best illustrate the application of my invention.
My invention is of course applicable to a device in which the impression cylinder
or cylinders print in but one direction.
I will now describe my second improvement, which relates to an improved means
for associating the product.
This consists in its first application of a double turner bar arranged in connection
B

page_text: with another turner bar and rolls parallel to the main movement of the web, so that
different width newspapers can be produced, as, for example, a newspaper six or seven
columns wide, as desired.
Reference to follow this description should be had to Figs. 18 and 19 on the 7th
sheet of the drawings.
The web after being printed, as before described, passes to the continuously running
feeding-out drum 42.
The feeding-out drum has three grooves 200, 201 and 202.
203 designates a slitter which may be adjusted to co-operate with either groove 201
or 202 to slit the web into two sections.
The groove 200 is arranged at the centre line of a longitudinal folder 122, and the
lower section of the web in Fig. 4 can be led directly to said longitudinal folder by
means of rolls 121 and 123, as indicated in Fig. 3.
The roll 121 preferably has a groove in line with the groove 200, so that the
central paste line can be properly carried to the former.
Arranged between said frames is a large shaft or pipe 119, adjustably secured on
which is a bracket 120.
Arranged between a bracket 125 extending in from the side frame 21 and said
bracket 120, are two turners 204 and 205 arranged in substantially the same
horizontal plane.
Also arranged between said bracket 120 and the side frame 20 is a turner.206.
Arranged in brackets projecting in from the side frame 20 are
four parallel
rolls 207, 208, 209 and 210.
By this arrangement four, six or eight-page papers or multiples thereof can be
produced of different widths, as for example, six or seven columns wide without the
adjustment of any of the turners, parallel-rolls or folder.
The following is the way this device is used, and in the following description, the
margins on the web outside the printed matter are neglected.
If a four-page six-column paper is wanted, a web 211 of a width equal to two
six-column pages is run through the machine, so as to come to the roller 42 with its
centre in line with the centre of the longitudinal folder, and the same is carried
directly to the longitudinal folder by means of rolls 121 and 123.
If a four-page paper seven columns wide is desired, a web 213 of a width
equal to two pages of seven columns wide is similarly run through the machine.
If an eight-page six-column paper is wanted, a web of a width equal to four pages
of six columns wide is run through the machine, and is slit on the groove 201 into
two webs 211 and 212:
The web 211 is passed directly to the former.
The web 212 is deflected up over the turner 205, up around the rolls 207 and 208,
and up over the turner 206 to come on top of the web 211.
If an eight-page seven-column paper is wanted, a web of a width equal to four
pages of seven columns is run, and the same is slit on the groove 202 into two webs
213 and 214,
The web 213 is passed directly to the former, and the web. 214 is led up over
the turner 204, up over the parallel rolls 209 and 210, and then up over the
turner 206.
If a six-page paper of six columns is desired, a web of a width equal to three
six-column pages is run through the machine, and is slit on the groove 201 into two
sections 212 and 215.
The section 215 is passed directly to the former, and the section 212 is deflected
around the turner 205 parallel rolls 207 and 208 and turner 206 to come on top
thereof.
If a six-page paper of seven columns width is desired, a web of a width equal to
three pages of seven columns each is run, and the same is slit on the groove 202 into
two sections 214 and 216.
The section 216 is passed directly to the former, and the section 214 is

page_text: deflected up over turner 204 parallel-rolls 207 and 208 and turner 206 to come on
top thereof.
The various turners and parallel-rolls before referred to are accurately set when
the machine is erected, and need not thereafter be adjusted.
The various rolls are so set that the sections of the web will register longitudinally
and transversely without adjustment of the forms; thus it will be seen that the
machine is ready to produce without adjustment, except of the slitter, any of the great
variety of products before mentioned, and that the adjustinent of the turners, etc., is
dispensed with.
This enables the pressman to very quickly thread the machine up for the proper
paper desired.
The figures before given are merely illustrative, and other relative sized papers may
be produced without departing from the scope of my invention.
This web associating mechanism, although especially useful in the style of machines
indicated, is also capable of general application.
A still further carrying out of this second improvement consists in using the same,
instead of for producing newspapers of different width, to produce either four, six,
eight or ten-page papers, which is done by providing an additional turner bar and
rolls.
Reference to follow the description of this modification should be had to the
eighth Sheet of the drawings, Figs. 20 and 21.
In this modification; the roll 42 has suitable grooves 115, 116 and 117 positioned
thereon, as shown in Fig. 20, the middle groove 116 being of a width sufficient to
allow the line of paste to clear the roll 42.
Suitable slitters are arranged to coact with the grooves 115 and 117.
Arranged between the bracket 125 and the bracket 120 is a forty-five degree
turner 130, and also arranged between a bracket 126 and said bracket 120 are two
turners 133 and 137.
Also arranged on a bracket 127. projecting inwardly from the frame 20 is a
turner 134.
Arranged in suitable brackets 128 projecting inwardly from the side frame 20 are
rolls 131 and 132, which I term "parallel rolls."
Parallel rolls 135 and 136 are also arranged in brackets 129, which project outwardly
from the frame 20.
The turners 133 and 137 are arranged in the same horizontal plane, and
the turners 130 and 134 are also arranged in substantially the same horizontal
plane.
The under surfaces of the turners 133 and 137 are above the top surfaces of
the turners 130 and 134 a distance substantially equal to the distance between the
bottom and top of the parallel rolls 131 and 132, and 135 and 136.
The roller 42 is preferably of a width a little greater than five pages of the web
(neglecting margins), so that four, six, eight, or ten-page papers can be produced, as
hereinafter described.
The central turning point of the turner 133 is arranged in the longitudinal line
of the folder 122, and the central turning point y of the turner 137 is arranged at
substantially one-half page width to one side thereof.
The groove 116 on the forwarding roller 42 is arranged in line with the centre of
the folder; and the grooves 115 and 117 are arranged at a distance from the groove 116
substantially equal to the width of a one-page section of web.
With this arrangement, four, six, eight or ten-page papers can be produced without
any adjustment of the turners, parallel rolls or folding device.
If a four-page paper is wanted, a section of web 138 two pages in width is run, and
is so positioned in the machine that it will come to the forwarding roll 42 between the
grooves 115 and 117, and will pass directly therefrom by means of roll 121 to the
longitudinal former.
If a six-page paper is wanted, a section of web three pages in width is run through

page_text: the machine, and is so positioned that it can be slit on the groove 115 into a two-page
section 139, and a one-page section 140.
The one-page section 140 is passed directly to the longitudinal folder by means of
the web-forwarding roll 121.
The two-page wide section of web 139 is deflected up over turner 130, up over
parallel rolls 131, and then is deflected up over turner 133 to the longitudinal former,
so as to come on top of the single-page section 1400.
If an eight-page paper is desired, a web of substantially four pages in width is run,
and the same is slit into two sections 138 and 139 on the groove 115 of the forwarding
roller 42.
The section 138 is passed directly to the former, and the section 139 is deflected to
lie on top thereof by means of turner 130, rolls 131 and 132, and turner 133, as before
described.
4
If a ten-page paper is desired, a web substantially five pages in width is 'run
through the machine, and is slit at the grooves 115 and 117 into two two-page
sections 138 and 139, and a single-page section 1400.
The section 138 passes directly to the former, and comes next thereto.
The section 1400 is led 'up over turner 134, up around rolls 135 and 136, and is
deflected by the turner 137 to lie on top of the section of web 139 at the right of the
centre line of the longitudinal former.
The section of web 139 is deflected by turner 130, parallel rolls 131 and 132 and
turner 133, to be laid on top of the single-page section, which has been previously laid
on top of the two-page section 138.
In this way, the most desirable way of leading the sections of web to the longi-
tudinal folder is accomplished.
It is desirable with the six-page product to have the small or one-page section of
web next to the former, and it is desirable to have the single-page web in the ten-page
paper between the two-page sections, and this can be readily accomplished without
adjustment of turners by the means before described.
I call the rolls 131 and 132 and 135 and 136 parallel rolls, because their 'axes are
substantially parallel to the principal movement of the web.
In some instances it may be found possible to use only a single roll in place of two
rolls for each section of web, but it is desirable in most cases to use two rolls so as to
keep the sets of turners some distance apart, so that the sections of web can be readily
threaded.
The turners and rolls are accurately set when the machine is built, and need not
thereafter be disturbed.
Of course the device herein shown can be used to produce different page products
than those previously described, and, of course, if a collector is used beyond the longi-
tudinal former, multiples of the products herein mentioned will be produced.
I will now describe my third improvement, which consists in providing a new
form of driving mechanism for the machine by which the machine can be advan-
tageously operated.
This third improvement is shown in the 9th, 10th and 11th sheets of the drawings,
and in Figs. 22 to 25 inclusive.
It will be noticed from the foregoing description of the first improvement, that the
entire feeding and manipulating mechanism for the web is driven from the pinion 156
which is keyed on the shaft 50, and that the entire cylinder driving mechanism is
driven from the bevel-pinion 51.
On the shaft 50 I have arranged a tight pulley 150, a loose pulley 151, and a small
loose pulley 152.
Also on the end of the shaft I arrange a fly or balance-wheel 153.
The shaft 50 is journalled in the side frame 20, and in a bracket 154 which extends
therefrom, as shown.
A shipper-rod 155 is arranged to pass across the machine, and the same
may be operated from the front side of the machine' by. any of the usual lever
mechanism.

page_text: The shipper carries belt-fingers 156. The same also carries a cam 157, bearing
against which is a pivoted arm 158, which carries a brake 159, which bears on the
balance wheel 153.
This mechanism is so arranged, that when the belt is thrown on the loose pulley 151,
the brake will be applied to the balance-wheel, to quickly stop the machine, and
so that when the belt is thrown on either pulley 150 or 152 the brake will be
released.
Secured to the loose pulley 152 is a pinion 160, which engages a gear 161
secured on the end of a shaft 162, which is journalled in a bracket 163 projecting
up from a bracket 154.
Secured to the gear 161 or to the shaft 162 is a pinion 164 which meshes with a
gear 165 loosely journalled on the shaft 50.
This gear 165 carries a pawl 166 which engages a ratchet-wheel 167 secured to the
shaft 50.
The pawl 166 is spring-pressed, and may he snapped in or out of operative
position.
Also secured on the shaft 162 is a pinion 168 which engages an intermediate 169
loosely journalled on the same stud as the intermediate 57.
Secured to the intermediate 169 is a pinion 170, which gears by a small inter-
mediate 171, loosely mounted on a stud, to a gear 172 loosely journalled on the
shaft 59 of the feeding-in drum 24.
Rigidly secured to the shaft 59 is a ratchet-wheel 173.
The gear 172 carries a pawl 174 which engages said ratchet-wheel.
The gear 58 also carries a pawl 175 which engages said ratchet-wheel 173.
The pawls 174 and 175 are disposed similarly relatively to the ratchet-wheel, and
these pawls are spring-pressed, and may be snapped out of operative position, if
desired.
By this improved gearing, the following operations can be accomplished.
The press can be run at full speed by throwing the belt on the tight-pulley 150,
when the gearing for the feeding and web manipulating devices will be driven through
the pinion 56, and the cylinders will be reciprocated by means of the bevel-
pinion 51.
By throwing the belt on to the pulley 152, the press will be driven at a slow speed
by the following train.
The rotation of the loose-pulley. 152 will turn the pinion 160. This will drive the
gear 161, and thus pinion 164 will drive the gear 165.
This provides for a reduction in gearing, so that the gear 165 will turn much slower
than the pulley 152, and power will be transmitted from the gear 165 to the shaft 50
by means of the pawl 166 engaging the ratchet-wheel 167, thus turning pinion 56
and bevel-pinion 51, and thus operating the press at a slow speed.
Now if pawl 166 should be thrown out of operative position and the belt thrown on
to the pulley 152, the shaft 50 would not be rotated, and thus the web feeding and
manipulating devices and the cylinders would remain out of operation, but the
shaft 162 would still receive motion and would transmit the same by gears
168, 169, 170, 171 and 172, pawl 174 and ratchet-wheel 173 to the feeding-in
drum 24. Thus the feeding-in drum alone would be turned at a very slow speed.
This is an advantageous construction in case of breakage.
The breakage of the web generally occurs in some part of the printing
mechanism.
By quickly stopping the machine and then driving the feeding-in drum only, the
incoming web can be advanced, so that the broken end thereof can be pasted. or
secured to the broken end of the web remaining in the press, and then the machine
can be started slowly, so that the new end of the web can be drawn through the
machine and associating mechanism without the necessity of rethreading the parts.
This mechanism thus enables the press to be much more quickly started in case of
breakage than in presses ordinarily built where the machine has to be entirely.
rethreaded.

page_text: It is also to be seen that the feeding-in device is driven under all conditions by a
pawl and ratchet mechanism, so that at every operation the feeding-in drum is free
to turn forward.
This is advantageous, in that it is generally the custom in this class of machines
to make the tension of the feeding-out device adjustable, so that under different
conditions the feeding-out device may demand a little more web than can be supplied
by the feeding-in device.
When this takes place in the old construction, the feeding-in device cannot supply
the extra web sometimes required, and therefore the web in the press will be put
under tension and broken.
However, if the above construction is used by which the feeding-in device is driven
under every condition through a pawl and ratchet mechanism, if an abnormal tension
should be put upon the web in the machine from the feeding-in device, the feeding-in
drum can turn slightly forward through its ratchet mechanism and thus the
additional web sometimes required by the feeding-out device can be supplied without
breaking.
It will also be seen that the pawl mechanism is so arranged that no accident can
take place.
Thus when the belt is on pulley 152 and the pawl 166 is in engagement with the
ratchet-wheel 167, although the gear 172 will be driven much slower than the
gear 58, even if the pawl 174 should be left in operation, no harm will be done,
because the ratchet-wheel 173 would simply turn away or forward relatively to the
pawl 174.
When the belt is on pulley 152, and the pawl 166 out of mesh, the only gearing
that will turn is the train which drives the gear 172, and during this operation, if
the pawl 175 remains in operative position, no harm will be done, as the ratchet
wheel 173 will simply be moved away therefrom by the pawl 174.
Further, if the pawl 166 is left in operative position and the press started at full
speed, the rapid rotation of the ratchet-wheel 167 will throw pawl 166 out of
operative position. Thus the normal position of the mechanism is with pawl 166 in
inoperative position and pawls 174 and 175 in operative position.
This arrangement is made for the reasons: first, so that in the regular operation
of the machine clicking from pawl 166 is done away with; second, so that the
machine is always in readiness to have instantaneous splicing if the web breaks.
The pawls 174 and 175 are usually always left in operative position, the clicking of
the pawl 174 being so immaterial that it may be neglected.
This gearing thus always provides for instant manipulation of the machine, no
matter what condition exists, and no matter what is to be done.
This gearing in its broad features is capable of general application, that is, to any
kind of web printing machine, and I intend to claim the same thus broadly.
The details and plans of the mechanisms herein described may be further varied
and developed and modified by a skilled mechanic without departing from the scope
of my invention, as expressed in the claims.
