Improvements relating to Printing Machinery.
1 HENRY EDWARD NEWTON of the Office for Patents, 6 Bream's Buildings,
Chancery Lane in the County of Middlesex, Patent Agent, 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:-
In the construction of web printing machines, especially for the production of
newspapers, it is frequently necessary to provide a press which may be used to print
a single main web forming the body of the newspaper; and, for certain issues, to
print, in addition thereto, a supplement of equal or less size.
It is desirable that machines of this character, especially in cases in which the
supplement is to be printed but seldom, should be so constructed that the main
web printing mechanism may be located in convenient position for change of plates
and other purposes, and that the machine may be readily changed when the
supplement is to be printed, and run at a high rate of speed for either product.
It is the object of one part of the invention to provide a simple and compact
machine provided with a main web-printing mechanism and a supplement web-
printing mechanism, so arranged that the main web-printing mechanism shall be in
convenient position for use when the supplement is not to be printed, and only a
change in the course of the web be necessary in shifting from one product to
another, and this object is attained in the present case by providing an auxiliary
set of type and impression cylinders, which are used when the supplement is to be
printed, and arranging one set of the main type and impression cylinders so as
to be used either as a part of the main web-printing mechanism, or as a part
of the supplement-printing mechanism.
While the main object of this part of the invention and the principal use of
the auxiliary cylinders is that stated above, these cylinders may be used with the
main type and impression cylinders, thus affording a convenient means for printing
one side of the web a second time in the same color, or in a color different from
that of the first impression. Such second impression is frequently desirable,
especially in display advertising, and the machine herein described affords a con-
venient means for this purpose, no change being necessary, except in the course
of the web. These auxiliary cylinders may be used as a part of the main web-
printing mechanism also whenever, on account of breakage or for any other reason,
it is not desired to use the supplement printing cylinders.
The object of another part of the invention is to provide means whereby each
main sheet may be provided with a small extra sheet, and further, to provide
means whereby such a sheet may be inserted between the plies of the main sheet
as it passes through the delivery mechanism.
In newspaper work, it is frequently desirable to insert news received after the
forms have been made up, or during the printing of an edition. In the web
printing machines heretofore in use, it has been necessary, in case of the receipt of
such late news, to change the plates, or to print a supplement sheet of a size
approximating that of the main sheet, which is often far in excess of the requirements
of the news to be added. This change of plates involves much labor, consumes
considerable time, and necessitates the stoppage of the machine, if the printing of
the edition has already been commenced. This delay is of great importance, as the
printing of the issue is always delayed until the last moment, in order to include
therein the news up to as late a time as possible.

page_text: All such delay is avoided by the present invention, which provides a simple
attachment to the delivery mechanism, by which each sheet of the issue may be
provided with a small extra sheet, the attachment being so constructed and arranged
as to occupy but a small space in the machine, and not interfere in any way with
the ordinary operations thereof, and to permit the addition of the extra sheet
without stopping the machine.
The use of this extra sheet, for the purpose of adding late news, is but one of the
many important advantages obtained by the invention. The "extra "affords also
a convenient and very desirable means of advertising, the pasting of a small sheet
upon any part of the main sheet of the paper attracting attention immediately, thus
serving as an advertising medium of especial value.
Another use to which the extra may be put, is, that of printing any special
matter which is not to form a permanent part of the paper, but which is to be
removed therefrom and used for any purpose. Such matter is at present used to a
great extent in the various voting contests of many newspapers, in which a vote is
printed in the paper, to be cut therefrom, and return to the publishers. A similar
use is found during elections, in which it is the practice of newspapers to publish
tickets of their respective parties, the tickets to be cut from the papers and deposited
as votes. Various other uses of this extra will readily suggest themselves, those
mentioned being but a few of the most important, and the extra may be made.
movable in whole or in part, or permanently attached to the paper, as preferred.

Figs. 10 and 11 show products of different form.
The printing end of the machine, embodying the first part of the invention, will
be first described.
Referring now to Figs. 1 to 3, A is the main, and A. the supplement web. The
main web printing mechanism consists of the two sets of type, and impression
cylinders 101, 102, and 103, 104, the type cylinders being provided with inking
mechanism of any ordinary form. As shown, the main web cylinders are arranged
parallel, and in substantially the same horizontal plane, and this is a convenient
arrangement, as it affords ready access to the cylinders, but the cylinders may be
arranged vertically, or in any other relative positions, without departing, from the
invention. Arranged in position to form a part of the main printing mechanism,
when desired, and preferably below the cylinders 101, 102, as shown, are the
auxiliary printing cylinders 105, 106, also provided with inking mechanism..107.
If desired, these cylinders may be thrown, out of operation, when, not in use, by
any suitable means. There is shown for this purpose a removable gear. 116, by
which cylinder 106 is geared to the impression cylinder 102, the latter being driven
from the main shaft 117 by a series of intermediate 118, and, transmitting move-
ment to the other members of the main web-printing mechanism, as usual in this

page_text: class of machines. By removing the gear 116, the auxiliary printing cylinders and
their inking mechanism are thrown out of operation.
Between the supplement web A' and the cylinders 103, 104, and preferably below
the latter, are the web turner 108 and the conducting rolls 109, 110, forming with
cylinders 103, 104, a supplement printing and perfecting mechanism of common
form. The operation of this meclianism being well known, need not be described
here further than that the web passes under conducting roll 110, between the
cylinders 103 and 104 at one end, where one side is printed, over roll 109 and
the web turner 108, by which the web is turned in the ordinary manner, returning
over rolls 109 and 110, and between the other ends of cylinders 103 and 104,
where the web is perfected.
This supplement web printing mechanism may be of any form, and placed in
any position in which the cylinders 103, 104 may be used in combination there-
with, but the mechanism and general arrangement shown involve the use of but
few additional parts, and these are place in a compact group conveniently
for use.
The operation will now be described.
Referring to Fig. 2, in which the supplement web A' is shown as not in use, it
will be seen that the main web A, as indicated in dotted lines, passes under the
conducting roll 111, upward between the type and impression cylinders 101, 102,
where it is printed upon one side, thence over the impression cylinder 102, under
the impression cylinder 103, and upward between the latter and type cylinder 104,
by which it is perfected, and whence it is carried over the conducting roll 112 or
roll 114, as preferred, to the conducting roll or pulley 113, the longitudinal folder a,.
and the delivery mechanism, all as is common in this class of mechanism, a
slitter S being also provided above the roll or pulley 13. for severing the web
longitudinally, before passing over to the folding mechanism, if desired.
When the supplement is to be printed, the main web will be led to the auxiliary
cylinders 105, 106, and the supplement web over turner 108, and to the
cylinders 103, 104.-The course of the webs will be as indicated in dotted lines in
Fig. 3. The main web passes downward between cylinders 105 and 106, where it
is printed upon one side, then around impression cylinder 106, and upward between
cylinders 101 and 102, by which it is perfected, and thence to the rolls 112, 113
and the folder a, as before. The supplement web A' is printed and perfected by
the cylinders 103, 104, in combination with the turner, as before explained, and, as
shown, passes from the cylinders over conducting roll 114 to roll or pulley 113,
where it is associated with the main web.
In web printing, and especially in newspaper work in which large editions are to
be struck off at the highest rate of speed, rendering frequent change of the tympan
sheet undesirable, it is usual, for the purpose of avoiding offset, to make the
perfecting impression cylinder of larger size than its type cylinder, in order that
the successive impressions may not fall on the same part of the cylinder, or to
provide this cylinder with special devices for this purpose. It is desirable, there-
fore, that the machine embodying the present invention should be so constructed
that the perfecting cylinders shall remain the same when the course of the main
web is changed for printing the supplement, and such an arrangement of cylinders
is shown in Fig. 4 and 5.
In these figs., the parts correspond generally to those of similar lettering in
Figs. 1 to 3, cylinders 101, 102, and 103, 104, forming the main web printing
mechanism, cylinders 103 & 104, being used for printing the supplement, and
cylinders 105 and 106 being the auxiliary cylinders. The relative arrangement of
the main cylinders is changed, however, so that the large impression cylinder 102
is always one of the perfecting cylinders in the modified construction, instead of.
being the first impression cylinder when one web is used, as in Figs. 1 to 3.
As shown in Fig. 4, the course of the main web, when used alone, is from the
web roll under conducting roll 111, upward between cylinders 103 and 104, around
large impression cylinder 102, and between it and type cylinder 101, to the

page_text: cnducting rolls 112, 113, and folder «, cylinder 102, thus forming the perfecting
impression cylinder. When the supplement is to be printed, the position of the
main web is changed, and the supplement web substituted for it, as shown in Fig. 5.
The course of the main web is then upward over conducting rolls 111, downward
between cylinders 105, 106, over large impression cylinder 102, and between it and
type cylinder 101, as before, cylinder 102 thus forming the impression cylinder for
the main web in both cases. The course of the supplement web, as shown, is
substantially the same as in Fig. 3.
For printing one side of the web a second time in a different color, as before
mentioned, the course of the web will be as follows, the supplement web not being
used. In the construction shown in Figs. 1 to 3, the web will first be led over
conducting roll 111, and downward between auxiliary cylinders 105, 106, to receive
the first impression, thence around cylinder 106, and onward, as shown in dotted
lines in Fig. 2, the web being perfected by cylinders 101, 102, and one side being
printed a second time by cylinders 103, 104, in a color different from the first
impression.
In the construction shown in Fig. 5, the web A' is not used, and the web A. is
led, as shown in dotted lines, till it has been perfected by cylinders 101, 102, when,
instead of passing to the folder, it is led around cylinder 102, downward around
cylinder 103, and then upward between the latter and type cylinder 104, by which
the second impression in a different color is made, the web passing thence to the
folder, as in the case of the supplement web.
The course of the webs, after leaving the printing cylinders, is immaterial in all
cases, so far as this part of the present invention is concerned, and any conducting,
associating, and delivery mechanism may be used.
It will be understood that, if desired, the cylinders 101, 102, and 103, 104, may
be used in combination with the turner, without using the auxiliary cylinders 105, 106,
the product being a sheet printed on one side and a perfected sheet. Other means
of varying the product will readily suggest themselves.
The main and supplement mechanism may be arranged for any width of sheet,
the relative length of the cylinder or number of plates used, being varied in
accordance with the product desired. The invention is not to be limited to any
special form of main printing mechanism or supplement printing mechanism, but,
as will be seen, consists in the general combination and arrangement of the printing
mechanisms as described and claimed.
The delivery end of the machine embodying the second part of the invention, will
now be described.
Referring to Figs. 6 to 8, it will be seen that the delivery mechanism to which
this part of the invention is applied, is of ordinary form, and a brief description of
this delivery mechanism will suffice. The longitudinal folder is of the common
form, consisting of the former A, provided with its internal turners a, over which
the web passes to and between the external turning rolls, and thence to the feeding
and folding rolls by which the fold is completed, and whence the longitudinally
folded web is led to the cutting and collecting cylinders B. C, which may be of any
ordinary form.
As shown, the cutting, collecting, and folding cylinders are of substantially the
construction shown and described in British Patent No. 1105, January 21st, 1890,
the cylinder B being provided with the sheet holding pins d, the folding blades e,
and cutting groove, and the cylinder C with the sheet-holding pins 7 and the
cutting blade h, the mechanism of the cylinders B, C, being operated respectively
by the stationary cams D, E, mounted in the frame of the machine.
The sheet or sheets is or are folded from the cylinders B, C between the folding
rolls, whence they pass over the guide to the control of the tapes m, by which,
if no additional fold is to be imparted, they are carried to the fly at the side of the
machine.
Under the control of the tapes m, the sheets are carried over a pair of folding
rolls F, between which, when desired, they may be folded by the folding blade G,

page_text: an adjustable stop a being provided to co-operate with the blade G, when the sheets
are to receive the second longitudinal fold. For operating the blade G, the shaft
of the roll C is provided with a cam H, which engages a bowl on the end of a rod o,
sliding through fixed guides p in the frame of the machine, and having, at its lower
end, a slotted connection with a crank arm on a short shafts, extending transversely
of the machine. This shaft s carries a second crank arm t, to the end of which the
folding blade G is secured.
Referring now to the parts forming the attachment, 10 is a bracket secured to
the inner frame of the delivery end of the machine, and provided with arms 11
extending forward beneath the folder. This bracket and its arms provide a support
for the printing, feeding, and turning mechanism of the extra attachment. Supported
in the arms 11. is a shaft 12, carrying at its rear end, outside the frame, a gear
wheel 13, which is operated from a gear on the end of the shaft of cylinder B
through a series of intermediates 14. This shaft 12 carries, next the frame of the
machine, a printing roller 15, and its forward end, beneath the former, carries a
roll 16, which rotates in contact with a roll 17, likewise carried in arms 11, the
roll 17 being driven from roll 16 by means of intermeshing gears 18. These
rolls 16, 17 form feeding and perforating rolls for the strip forming the extra
web the rolls being provided respectively with the usual groove and perforating
blade. These rolls are also provided with narrow rubber bands at each end, to grip
the edges of the paper for feeding.
On a bracket 19, attached to one of the arms 11, is secured a turner, consisting
of two bars 20, 21, set at an angle to each other in a vertical plane, so that the web
from the printing roller 15 passes upward over the bar 20, across the turner, and
downward over the bar 21, to the feeding and perforating rolls 16, 17.
Mounted to rotate in contact with the printing roll 15, is the impression roll 22,
against the surface of which rotates also the pasting roll 3, receiving paste from a
paste fountain 4, secured to a bracket 23, extending inward from the frame of the
machine, this pasting roll being constructed, as shown in Fig. 7, to lay a narrow line
of paste on the edge of the extra.
The printing roll 15 may be inked by any suitable means. It is preferable,
however, to use an ordinary aniline roll and for rolls for conveying the ink to the
type roll, the inking and form rolls being shown respectively in dotted lines at 5, 6
in Fig. 6.
The extra web X is led from a web roll 24, mounted on a bracket 25 in the frame
of the machine, over a conducting roll 26, downward around the impression roll 22,
where it receives a line of paste from the paste roll 3, thence upward between the
printing roll 15 and impression roll 22, where it is printed, and passes thence
upward between the turning bar 20, across the turner, and downward over the
turning bar 21, to the perforating and feeding rolls 16, 17, where it is perforated.
From the rolls 16, 17, the web, partially severed, passes between the external
turning rolls to the feeding and folding rolls c for the main sheet. The mechanism
for feeding the extra will be geared to run at a lower rate of speed than the rolls
so that as the leading edge of the web X reaches the rolls c, it will be separated by
the accelerated rolls on the line of perforation, and will thus, as the main sheet
passes between the folding rolls, be inserted between the plies of the main sheet,
and pasted thereto, as shown in Fig. 10.
C
C;
The extra feeding and perforating rolls may be placed in any position width-wise
of the web A, so that the extra will be imposed upon the main sheet, either at the
edge, as shown, or at any point between the edge and the central fold. By
adjusting the lead of the "extra" relatively to the main web, it is evident that the
position of the extra may be varied lengthwise of the sheet, as desired.
It may sometimes be desirable to furnish a main sheet with two or more extras
at different points lengthwise of the sheet. This may readily be done by varying
the speed of the supplemental mechanism. When the sheets are to be collected
also, it is thus possible to provide only each alternate sheet with the extra, so

page_text: that a product of the machine, though consisting of two sheets, shall contain but
one extra.
Any suitable means may be used for thus increasing or diminishing the speed of
the extra web. In Figs. 6 and 7, a convenient construction is shown, in which the
shaft of the intermediate 14, next the gear 13, is provided with a second smaller
gear 30. The shaft of the printing roller is extended beyond the gear 13, to afford
support for a larger gear 31, shown in dotted lines in Fig. 7, which meshes with
gear 30. By removing gear 13 from its shaft, and substituting gear 31, the speed
of the extra mechanism will be varied, and by other combinations of gears, any
desired adjustment may be obtained.
It will be understood that, as is common in delivery mechanism, the web, as before
remarked in connection with Figs. 1-5, may be split by a splitter S, as shown in
dotted lines in Figs. 6 and 7, before passing over the longitudinal folder.
In this case, the main sheet will be formed from two webs, the extra being
inserted between the plies, as before.
Other common methods of associating two webs to form a single sheet, may be
used, as the invention is not to be limited to the special form of delivery mechanism
shown, and the insertion of the extra sheet between the plies of the main sheet, as
the plies are brought together, being applicable, whether the sheet is formed from
a single folded web or two webs.
From an inspection of Figures 6 and 7, it will be seen that almost the entire extra
mechanism is placed out of the way beneath the former, and that this location of
the attachment enables the extra sheet to be led downward in a direct vertical line
between the plies of the main sheet, which thus guide it slightly. This combination
of the supplemental mechanism with the longitudinal folder, is, therefore, the
preferred construction, but it is to be understood that the supplemental mechanism
may be combined with other parts of the main delivery mechanism, and placed in
any desired position relative to the lead of the main web, without departing from
the invention.
In Figure 9, the combination of the extra attachment with another part of the
delivery mechanism is shewn, the extra being inserted between the plies of the
main sheet, as the latter is folded between the rolls F, so as to be upon the outside
of the sheet when opened, this form of product being shewn at Figure 11.
In this case, also, as with the construction shewn in Figures 6 to 8, the extra may
be severed from the web X by the accelerated feeding and folding rolls for the
main sheet, but a construction is shewn by which the extra is entirely severed
prior to reaching the rolls F, F, and associated with the main sheet under separate
sheet form.
In this construction, the web X, after passing the perforated rolls 16. 17, passes
into the control of tapes 27, by which it is carried forward to the rolls 28, between
which the sheet is nipped and severed from the web, the rolls 28 & tapes 27 being
accelerated to a speed beyond that of feeding rolls 16. 17. From the rolls 28, the
severed extra passes between guides 29 to the folding rolls F, where it is inserted
between the plics of the main sheet.
It is evident that, in this construction also, the number of the extras imposed
upon the main sheet, and the position of the extra thercon, may be varied, as
previously described. By the use of two attachments, one with each folder, as
shewn, it is evident that one extra may be placed on the inside and another on the
outside of the main sheet.
It is evident that many changes may be made in the attachment. Thus, the
pasting mechanism may be omitted, and the extra be simply inserted between the
plies of the main sheet, or the perforators may be omitted, and a web of previously
perforated paper be employed. The special form of mechanism may be varied
widely, and other common forms of printing attachments, such as a numbering
mechanism, may be added, if desired. Many other modifications will suggest them-
selves to one skilled in the art,

page_text: w me one form of mechanism for printing one side of the extra web is shewn and
described, it will be understood that this invention is not to be limited to any special
form of printing mechanism, but that other forms of printing mechanism may be
substituted, either to print but one side, or to perfect the web.
The extra is shewn, and has been described, as inserted between the plies of the
main sheet during the process of folding, and this method is preferable, because the
extra is thus held in position during attachment by pressure between the plies of
the sheet, and may, moreover, be introduced and held in position without
pasting
It will be understood, however, that the invention is not to be limited to this
feature, but covers broadly the combination with the delivery mechanism, of the
extra mechanism as claimed, independently of any special manner in which the extra
is associated with or attached to the main sheet.
