Improvements in Web Printing Machines.
I HENRY EDWARD NEWTON of The Office for Patents, 6 Bream's Buildings,
Chancery Lane in the County of London, Patent Agent, do hereby declare the
nature of this invention to be as follows:-
The object of this invention is to produce a machine adapted for printing &
perfecting a web, and also for color printing, when desired.
This object is attained by combining with a web-printing and perfecting
mechanism, controlling devices operating to present a web of less width than the
capacity of the printing surface to different portions of the same, for multiple
impressions, so that the printing mechanism may be used for perfecting a full width
web, or printing in colors on a web of less than full width, as desired, or by
combining with a plurality of web printing mechanisms capacitated to print and
perfect a plurality of webs, web-controlling devices coacting therewith, to present
a web of less width than the capacity of the printing surfaces to different portions
of the printing surface of some or all of the printing devices, so that the printing
mechanisms may be used for perfecting a plurality of full-width webs, or printing
in colors on a web of less than full width, as desired; or a plurality of web-
printing mechanism are combined with web-controlling devices, so as to print and
perfect a plurality of webs, or to coact in printing with multiple impressions on a
web of less than full width, whether upon a single narrow web or a plurality of
narrow webs simultaneously; or a plurality of full width webs may be perfected,
or a plurality of webs of less than full-width printed, one of which webs, of less
than full width may be perfected, and the other printed in colors, or both webs, may
be printed in colors. It will thus be possible to print and perfect a plurality
of full-width webs at high rates of speed, or it may be possible to produce,
at correspondingly high rates of speed, the most desirable products in color
printing.
In carrying out this invention, two sets of type and impression cylinders, forming
web printing and perfecting mechanisms, are employed, provided with inking
mechanisms of any suitable construction, the ink fountains being divided into two
parts, so that the opposite ends of the type cylinders may be inked in different
colors, when desired. The delivery mechanism may be of any suitable form
capacitated to deliver products of different widths. A web transferrer, a web
reverser and transferrer, and a second web transferrer, are combined with this
arrangement of web printing mechanism. The web-transferrers may consist of the
well-known two parrallel bars, and the web reverser and transferrer may be the
common web turner consisting of two converging bars.
In order to print and perfect, by this arrangement of mechanism, a full-width
web is led from the web roll between the first pair of type and impression cylinders,
to receive the first impression; thence around the upper and lower portions
of the periphery of the impression cylinders, and between the second set of type
and impression cylinders, to receive the second or perfecting impression, and thence
directly to the delivery mechanism.
To print a half width web in four colors on one side, the half width web is led
from the web roll between the second set of type and impression cylinders at one

page_text: end, where it receives the first impression, thence about the impression cylinder,
and over a web-transferrer, by which it is transferred without reversing, and again
passes between the second set of cylinders at the opposite end, receiving a second!
impression on the same side as the first, and in a different color, thence over the
impression cylinder, to a web turner, by which the web is reversed and transferred,
and led between the first set of type and impression cylinders, receiving a third
impression on the same side, thence over another web transferrer, to and between.
the first type and impression cylinders at the opposite end from that of the third
impression, receiving a fourth impression on the same side, and thence to the
delivery mechanism."
To print a half-width web in two colors on each side, the course of the web may
be the same as before, except that the passage over the first turner is omitted, the
web passing to the first set of type and impression cylinders, receiving thereby two
impressions on the same side, in different colors, from opposite ends of the second set of
cylinders, and then two impressions on the same side in different colors from opposite
ends of the first set of cylinders. Two impressions on one side and one on the other
may readily be given by omitting the impression from one end of either of the sets
of cylinders, or two impressions on one side and none on the other, by omitting
both impressions from the first pair of cylinders.
To print in three colors on one side of a perfected half-width web, the web
receives its first impression, as before, at one end of the cylinders; is then reversed,
and transferred by the turner, to receive its perfecting impression on the opposite
side from the opposite end of the cylinders; and is then led directly to the first set
of type and impression cylinders, and receives two more impressions upon one side,
after being transferred by the transferrer.
Sometimes one transferrer and one reverser and transferrer may be employed, the
web printing and perfecting mechanism being the same as before. A common web
turner and transferrer are mounted respectively below and above the first pair of
type and impression cylinders.
For perfecting, the lead of the full-width web is the same as before. For
printing three colors on one side and one on the other, a half-width web is led to
the first set of type and impression cylinders; the web being reversed and transferred
by a web turner, receives a second impression on one side from one end of these
cylinders, passing thence over a transferrer, and between the second set of cylinders
at the opposite end, having thus received three colors on one side and one on the
⚫other.
Two type-cylinders and one impression cylinder may also be used, the two type-
cylinders being so located relatively to a single impression cylinder, as to print upon
the same side of the web. The full width web may be reversed for perfecting by a
web reverser, and upon the opposite side of the impression cylinder from the web
reverser is placed a web-transferrer.
To print and perfect a full-width web, the web is led from the first type and
impression cylinder through the adjoining web reverser, to the second type cylinder,
coacting with the impression cylinder.
To print a half width web in four colors on one side, the web is led to one end
of the first type cylinder, thence direct to the second type cylinder, these two
impressions being made at the same side, and at the same end of the cylinders,
thence through a transferrer to the opposite end of the cylinders, thence to the
first and second cylinders, as before, whence the web, printed in four colors, passes
to the delivery.
To print three colors on one side and one on the other, the half width web is
to receive its first impression from the first type cylinder; is then reversed, and
receives a second or perfecting impression from the same end of the second type
cylinder is then transferred to the opposite end of the cylinders by the second
transferrer, and passes to the delivery mechanism.
To print two colors on each side, the half width web is perfected by the two
sets of type cylinders, at one end, by means of a reverser; is then transferred by

page_text: a transferrer, and again perfected in like manner at the opposite end of the
cylinders.
A single type and impression cylinder, at the opposite ends of which the web
receives the printing and perfecting impression, may be employed, a web turner
being used to reverse and transfer the web for the perfecting impression, and,
by combining these three web transferrers, a half width web may be printed in
four colors on one side. By using the two outside web transferrers, and reversing
the web after the second impression by the web turner, three colors on one side
and one on the other may be obtained.
In some cases, the printing mechanism, consisting of two sets of type and
impression cylinders forming one full width web-perfecting mechanism, and a
corresponding set of type and impression cylinders forming a second full-width
web-perfecting mechanism, may be employed, each provided with suitable inking
mechanisms, so as to constitute each a separate machine, or it may be a duplex-
web machine, with a common delivery.
With these web-perfecting mechanisms, there is combined a web reverser and
transferrer, consisting of two converging bars, and a web reverser, consisting of
three bars, arranged to reverse without transferring.
To print and perfect two full-width webs, the first web is led between the first
and second type and impression cylinders, and the second web between, the first and
second type and impression cylinders of the other web perfecting mechanism ;
then to the delivery mechanism, where it is associated with the first web, forming
a two-ply web, which may be divided longitudinally into two narrower webs.
To print two half-width webs, one perfected in one color on each side, and the
other in five colors on one side and one on the other, one web is led over the rear
ends of the second set of type and impression cylinders.
The other web to be printed, in five colors on one side and one on the other, is
led to and between the rear ends of the first and second pairs of cylinders in
succession; then passes to a web reverser and transferrer; the perfected web thus
brought to the front end of the cylinders, passes again to the first pair of
cylinders, receiving from the front ends of the cylinders a second color, thence
directly to the type and impression cylinders of the second set, whereby a third
color is imprinted on this side; thence past the web transferrer and reverser,
around the web-reverser; by which the web is reversed, without transferring;
between the second pair of cylinders of the first set, receiving a fourth color,
from the front ends of these cylinders, and to the second pair of cylinders of the
second set, receiving a fifth color.
By the use of a simple transferrer in place of the reverser and transferrer, the
five colors may be printed upon the side which receives the first impression.
It will be understood that various other products may be produced by simply
varying the path of the web.
Two perfecting mechanisms of the kind above described may be employed in
combination with two web reversers and transferrers, so as to print and deliver,
associated together, two webs of less than full width, the one web being printed
with four colours on one side and one on the other, and the other web with three
colors on one side only.
One web is led between the type and impression cylinders of the first set of
printing and perfecting mechanism at the rear of the machine, thence to the
cylinders of the second set, and over a web reverser and transferrer, by which the
web is reversed and transferred to the front of the machine; thence back to first
cylinders, and out between the cylinders of the second set of mechanism, the web
being printed with four colors on one side and one on the other.
The other web is led to the second set of cylinders at the rear of the machine,
over a reverser and transferrer, to the front of the machine; between the second
pair of cylinders of the first set, & out by the cylinders of the second set, printed
in three colours on one side only.
If two webs, each printed in three colors on one side and one on the other, are

page_text: r
J
desired, one web may be printed and perfected by the cylinders of the first set,
passed to the second set, then reversed, and transferred to the front of the
machine, and completed by the remaining pair of cylinders of the second set.
The other web may be led to the second set of cylinders at the rear of the
machine, to a reverser and transferrer, and thence to the first set of cylinders at
the front of the machine, and out between the cylinders of the second set, as
before.
It will be understood that the printing mechanisms above described may form
independent machines, or may be combined with other web-printing mechanism to
form a machine printing from a plurality of webs.
The mechanisms above described are also adapted to perfect double-width webs,
or to print in colors a single-width web; and it will be understood that the terms
"half width," and "less than full width," used herein, refer not to the size of a
page, but to the capacity of the printing mechanism, and that this invention may
be embodied in machines printing webs of any width, according to the product
desired.

COMPLETE SPECIFICATION.
Improvements in Web Printing Machines.
I HENRY EDWARD NEWTON of The Office for Patents 6, Bream's Buildings,
Chancery Lane in the County of London, 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 newspaper printing, it is often desirable to print a part of a paper in colours,
while it is undesirable to further increase the size and complication of rapid web
printing machines by additional printing mechanism for such colour printing, and
the cost of such machines of high capacity, and the extra floor space required,
prevent the general use of separate colour printing machines.
In all newspaper
offices, moreover, in which multicolour printing is ever desirable, the advantage of
a construction enabling such colour printing from printing mechanism, the full
capacity of which is available for web perfecting, will be readily recognized.
One object of the present invention is to provide a web printing mechanism
capacitated to print and perfect a web, or to print in multiple impressions from the
same printing devices, and this object is obtained by combining with a web-
printing and perfecting mechanism, web-controlling devices operating to present a
web of less width than the capacity of the printing surface, to different portions of
the same, for multiple impressions, so that the printing mechanism may be used for
perfecting a full-width web, or printing in colours on a web of less than full width,
as desired.
A further object of the present invention is to provide an improved construction
of web-printing machines by which the full capacity of the printing devices may
be utilized for web-perfecting, or multiple impressions for colour printing be taken
therefrom, and this object is attained by combining with a plurality of web
printing mechanisms capacitated to print and perfect a plurality of webs, web-
controlling devices co-acting therewith to present a web of less width than the
capacity of the printing surfaces to different portions of the printing surface of
some or all of the printing devices, so that the printing mechanisms may be used
for perfecting a plurality of full-width webs, or printing in colours on a web of
less than full width, as desired.
While such combinations are claimed broadly, and the invention includes a con-
struction in which a plurality of web printing mechanisms are combined with
web-controlling devices, so as to print and perfect a plurality of webs, or to co-act

page_text: in printing in multiple impressions on a web of less than full width, whether upon a
single such narrow web or a plurality of narrow webs simultaneously, it is possible
by this invention to provide a construction by which a plurality of full width webs
may be perfected, or a plurality of webs of less than full width printed, one of
which webs of less than full width may be perfected, and the other printed in
colours, or both webs printed in colors. A construction is thus provided which
will print and perfect a plurality of full-width webs at high rates of speed, or
may be used to produce, at correspondingly high rates of speed, the most desirable
products in colour printing, and under this invention it is intended to include also,
broadly, such a construction.
It is evident that the invention, broadly considered, may be applied in connection
with web printing mechanisms of any suitable form, that the web controlling devices
for guiding the web for colour-printing may be of any suitable construction, and
that many different arrangements of the two may be made in accordance with the
result desired.
In the accompanying drawings, forming a part of this Specification, there are
shown constructions embodying the invention in two of the preferred forms, certain..
features in which constitute specific parts of this invention, and from a detailed
description of these constructions, the application of the invention in other con-
structions will be obvious to those skilled in the art.
In the drawings
Fig. 1 is a longitudinal sectional diagram, taken inside the frame, of a construction
embodying the first part of the invention as applied to web printing and perfecting
mechanisms having two type and impression cylinders, and showing the course of
the web in perfecting.
Fig. 2 is a similar view showing the course of the half-width web in printing
four colours on one side.
Fig. 3 is a plan view corresponding to Fig. 2.
Fig. 4 is a view similar to Fig. 2, showing a modified form of a machine in the
operation of printing three colours on one side of the web and one on the other.
Fig. 5 is an end view, looking to the left from the line 5 of Fig. 4.
Fig. 6 is a view similar to Fig. 1, shewing a construction embodying the inven-
tion as applied to a web-printing and perfecting mechanism having one impression
cylinder.
Figures 7 to 14 shew constructions for perfecting two webs, or printing in
multiple impressions on either one or two webs, these constructions embodying the
second part of the invention.
Fig. 7 is a longitudinal sectional diagram, taken inside the frame, of a con-
struction with two web perfecting mechanisms of a common form, each having two
sets of type and impression cylinders, and so combined as to permit the perfecting
of two webs, each the full width of the machine, or the printing of a plurality of
narrow webs with a number of impressions on one or both sides, this figure
shewing the course of the two full-width webs in perfecting simply, that is,
printing one impression on each side.
Fig. 8 is a similar view showing the course of the webs in printing two webs
of less than full width, one being perfected simply, and the other printed with
five impressions on one side and one on the other."
Figure 9 is a similar view, shewing the course of the latter web alone.
Figure 10 is a plan view corresponding to Figure 8.
Figures 11 to 14 show another construction embodying the second part of the
invention.
Figure 11 is a view similar to Figures 7 to 9, shewing the course of the webs in
printing two webs of less than full width,- -one web being printed with four
impressions on one side and one on the other, and the other with three colours on
one side.
Figures 12 and 13 are similar views, shewing respectively the course of the
former and latter webs alone.

page_text: Figure 14 is a plan view corresponding to Figure 11.
Referring now to Figures 1 to 3, A. B and C, D are two sets of type and
impression cylinders forming a web-printing and perfecting mechanism, A. C being
the respective type cylinders provided with inking mechanisms E of any suitable
construction, the ink fountains being divided into two parts, as shown in Figure 3,
so that the opposite ends of the type cylinders may be inked in different colours
when desired. The delivery mechanism F may be of any suitable form capacitated
to deliver the products of different widths, that shewn having the pair of
longitudinal folders commonly employed in double width machines, one half of the
divided full-width web being folded by each folder, and the colour printed half-
width web by the folder on one side. With this web-printing and perfecting
mechanism, there is combined in the construction shown in Figures 1 to 3, a web
transferrer G, a web reverser and transferrer H, and a second web transferrer I.
These parts may be of any suitable construction, so that the web transferrers will
operate to transfer the web from one end of the type and impression cylinders to
the opposite end, without reversing, and the web reverser and transferrer H will
operate to both reverse and transfer the web. As shewn, the web transferrers G. I.
are of the common form, consisting of two parallel bars, and the web reverser and
transferrer H is the common web-turner consisting of two converging bars.
The lead of the web is as follows:-
For perfecting, as shown in Figure 1, the full-width web a is led from the web
roll around a conducting roll 10, and upward between the first pair of type and
impression cylinders A B, where it receives the first impression, thence around the
cylinder D, and between the second set of type and impression cylinders CD,
where it receives the second or perfecting impression on the opposite side, the
perfected web passing thence directly to the delivery mechanisın.
For printing a half-width web in four colours on one side, as shown in Figures 2
and 3, the half width web is led from the web roll under a conducting roll 11,
upward between the second set of type and impression cylinders C. D, at one end,
where it receives the first impression; thence about the impression cylinder D and
a conducting roll 12, to and over the web transferrer G, by which it is transferred
without reversing ; thence around a conducting roll 13, and between the
cylinders C. D at the opposite end from that of the first impression, and receives a
second impression on the same side as the first, and in a different colour; thence
over the impression cylinder D and conducting roll 14, to the web turner H, by
which the web is reversed and transferred; thence about the cylinder D, at the end
at which the first impression was made, and upward between the first set of type
and impression cylinders A. B, where it receives a third impression on the same
side from one end of the cylinder A; thence about the conducting roll 15 and over
the web transferrer I, by which it is transferred without reversing; thence about
a conducting roll 16, and downward and around the impression cylinder B, and
upward between the type and impression cylinders A. B, at the opposite end from
that of the third impression, where the web receives a fourth impression on the
same side; and thence the web, printed in four colours on one side, passes over the
-conducting roll 15 to the folder on one side of the delivery mechanism F.
For printing a half width web in two colours on each side, the course of the web
is the same as just described, except that the web is not led over the turner H after
the second impression, but directly about the cylinder D, and to the first set of
type and impression cylinders A. B, so that the web receives two impressions on
the same side, in different colours, from opposite ends of the cylinders C. D, and
then two impressions on the same side, in different colours, from opposite ends of
the cylinders A B, and it is evident that two impressions on one side and
one on the other may readily be given, by omitting the impression from one
end of either of the sets of cylinders, or two impressions on one side and
none on the other, by omitting both impressions from the cylinders A. B, and
leading the web to the delivery mechanism F directly from the cylinders C. D
after the second impression therefrom.

page_text: For printing in three colours on one side of a perfected half-width web, or, in
other words, printing the web with one colour on one side and three on the other,
the web receives its first impression at one end of the cylinders C. D, as previously
described, and is then reversed and transferred by the turner H, so as to receive
its second or perfecting impression on the opposite side, from the opposite end of
the cylinders C. D, the transferrer G not being used, and is then led directly about
the cylinder D to the first set of type and impression cylinders A. B, and receives.
two more impressions upon one side, being transferred by the transferrer I, and
passing to the delivery mechanism, as before.
While it is not absolutely essential for the web to be transferred to the opposite.
end of the cylinders by the reverser H, but it is obvious that the products.
described may be secured by simply reversing the web without transferring, the
construction shown, in which the reverser H acts also as a transferrer, is preferred.
In Figures 4 and 5 is shown a construction employing but one transferrer and
one reverser & transferrer, but having the same capacity as that just described,
except that all four impressions cannot be placed on the same side. The con-
struction of the web-printing and perfecting mechanism is the same as before,-a
common web turner K and transferrer L being mounted respectively below and
above the first pair of type and impression cylinders A B.
For perfecting, the lead of the full-width web is the same as before. For printing
three colours on one side and one on the other, as shown in Figures 4 and 5, the half
width web y is led from the web roll about the conducting roll 17, to the first set of
type and impression cylinders, the web being reversed, and transferred by the web
turner K and conducting roll 18, as usual in such constructions; thence passes about.
the impression cylinder D, and receives a second impression on one side from one
end of these cylinders; thence over the conducting roll 19, transferrer L, and
conducting roll 20, to and between the cylinders C. D. at the opposite end, where.
it receives another impression on the same side as the first impression from these
cylinders, and then passes to the delivery mechanism F, printed in three colours on
one side and one on the other. If only two colours on one side be desired, it is.
evident that the web may be led from the cylinders C. D to the delivery mechanism.
after the first impression from these cylinders.
In Figure 6 is shown a construction embodying my invention as applied to a
web-printing, and perfecting mechanism having but one impression cylinder. In:
this construction, the two type-cylinders A. C. are so located relatively to the
single impression cylinder B, as to print upon the same side of the web, if the latter
be led directly about the cylinder, and the full width web is reversed for perfecting.
by a web reverser M, which may be of any suitable construction, to reverse the
web without transferring, but is preferably of the common, and now well known
form, consisting of three bars arranged as shewn and described in U.S.A. Patent.
No. 212,444, dated February 18th 1879. Upon the opposite side of the impression
cylinder B from the web-reverser M, is placed a web-transferrer N, preferably of the:
common form, consisting of two parallel bars similar to transferrers G. I. L. in the
constructions previously described.
The course of the web is as follows:-
For perfecting a full-width web, the web is led from the web roll about the
conducting roll 20, upward between the cylinders A. B, where it receives its first.
impression from type cylinder A; thence over the conducting roll 21. & web
reverser M, by which the web is reversed; then about the conducting roll 22 and
between the cylinders B. C, where it receives the second or perfecting impression
from the type cylinder C on the opposite side from the first impression, and the
perfected web then passes over conducting roll 23 to the delivery mechanism, F.
For printing a half width web in four colours on one side, as shewn in Figure 6,
the web is led to one end of the type and impression cylinders A. B, and then.
passes directly about the cylinder B, and receives the second impression on the
same side from the second type cylinder C,-these impressions being made at the
same end of the cylinders; thence about the conducting roll 24 and transferrer N',.

page_text: .
and is transferred to the opposite end of the cylinders, and then passes about the
conducting roll 25 to the cylinders A. B, and onward to cylinders C, as before,
receiving two more impressions on the same side from the opposite end of the
cylinders A. C, the web, printed in four colours on one side, then passing to
the delivery F.
For printing three colours on one side and one on the other, the half width web
receives the first impression from the type cylinder A; is then reversed by the
web reverser M, & receives a second or perfecting impression on the opposite
side from the same end of the type cylinder C; then is transferred to the
opposite end of the cylinders by the transferrer N, and passes directly about the
cylinder B to the delivery mechanism, receiving two additional impressions on
the perfected side from the type cylinders A, C, at the opposite ends from the first
impression.
For printing two colors on each side, the half-width web is perfected by the type
cylinders A. C, at one end, being reversed by the web revereer M, and is then
transferred by the transferrer N, and again perfected at the opposite end of the
cylinders, being reversed by the web reverser M, as before, and then passes to the
delivery mechanism F. For printing two colors on one side and one on the other,
the plates may be omitted from one end of one of the cylinders.
In the constructions thus far described, the web-printing and perfecting
mechanisms have two type cylinders, but it is evident that the invention may
be applied also to web printing and perfecting mechanisms of the other classes.
For instance, the invention may be applied to a web-printing and perfecting
mechanism of that class employing a single type and impression cylinder, at the
opposite ends of which the web receives the printing and perfecting impression,
a web turner being used to reverse and transfer the web for the perfecting
impression. Thus, by combining with such a construction, three web transferrers
similar to transferrers G, I, L, of the construction previously described, a half-
width web may be printed in four colors on one side, being transferred successively
to different portions of the type cylinder without reversing, and by using the
two outside web transferrers and reversing the web after the second impression by
the web-turner, three colors on one side and one on the other may be obtained.
The construction shown in Figures 7 to 14, embodying the second part of the
invention, will now be described.
Referring now to Figures 7 to 10, A. B and C. D, are the two sets of type
and impression cylinders forming one full-width web-perfecting mechanism,
and A', B and C, D' the corresponding set of type and impression cylinders of
a second full-width web-perfecting mechanism, A, C, and A' C₁ being the
respective type cylinders, and provided with inking mechanisms E' of any suitable
form. These web-perfecting mechanisms may be provided with separate deliveries,
if desired, or may constitute each a separate machine, the web being led from one
to the other in colour printing, but they are shewn as forming a duplex web
machine, and having a common delivery F, which may be of any suitable form,
capacitated to deliver products of different widths, that shewn having a pair
of longitudinal folders and the slitter commonly employed in double-width
machines, each half of the divided web, single or two ply, being folded by its
respective folder.
With these web-perfecting mechanisms, there is combined in the construction
shewn in Figures 7 to 10, a web reverser and transferrer H, and a web reverser M.
These parts may be of any suitable construction, so that the web transferrer and
reverser will operate to transfer the web from one end of the type and impression
cylinders to the opposite end, and reverse it simultaneously, and the reverser operate
to reverse the web without transferring. As shewn, the web transferrer and
reverser H is a common web turner, consisting of two converging bars, and the web
reverser M is of the common form, consisting of three bars arranged to reverse the
web without transferring, such ordinary form of web reverser being described and
shewn in the U.S.A. Patent above referred to.

page_text: The paths of the webs are as follows:-
In perfecting two full width webs, as shewn in Figure 7, the first web x is led
around conducting rolls 1. 2, and downward between the first type and impression
cylinders A. B, then around cylinder B, and upward between the second type &
impression cylinders C. D, whence the perfected web passes to the delivery
mechanism F. The second web y passes upward between the first type and impression
cylinders A B of the other web-perfecting mechanism, then around the impression
cylinder D', and downward between it and the type cylinder C, whence the per-
fected web passes around conducting rolls 3. 4, to the delivery mechanism F, where
it is associated with the first web,--forming a two-ply, web, which is divided
longitudinally into two. narrower webs, which are led to their respective longitudinal
folders.
In printing two half-width webs, one perfected simply, or printed in but one
colour one each side, and the other in five colours on one side and one on the other,
as shewn in Figure 8, the first mentioned web y is led over one end of the type and
impression cylinders A' B and C D in the usual manner. For convenience this.
web is shewn as led over the rear ends of these cylinders, and the web over their
Iront ends, but it will be understood that this may be varied.
.:
In printing the web z in five colors on one side and one on the other, as shewn in
Figures 7 and 8, the web is led to and between the rear ends of the cylinders A B
and CD in the usual manner; then passes around the impression cylinder D, to and
under the conducting roll 5, and around web reverser and transferrer H, by which
the web, perfected at the rear ends of the cylinders A B and C D, is reversed, and
transferred to the front of the machine, thence over the cylinder B, between it and
type cylinder A receiving from the front ends of cylinders A B a second color on
the side which received the second or perfecting impression; thence directly to the
type and impression cylinders A¹ B', whereby a third color is imprinted on this
side; thence around cylinder B', and between it and impression cylinder D', past
the web-transferrer and reverser H, between cylinders D and B, and over
conducting roll 6, to and around the web-reverser M, by which the web is reversed
without transferring thence over the conducting rolls 7. 8, to and between the
cylinders C. D, whereby a fourth color is imprinted by the front ends of these
cylinders: thence directly to the cylinders C³, D', receiving a fifth color; whence
the web, now printed with five colors on one side and one on the other, passes under
the conducting rolls 3, 4 to the delivery mechanism F, and is folded by one of the
longitudinal folders thereof, while the other web y, abreast web e on the rear of the
machine, is folded by the other longitudinal folder.
In this construction, the five colors are upon the side which receives the second
or perfecting impression, but it will be understood that if a simple transferrer,
consisting of the usual two parallel bars, be substituted for the reverser and
transferrer H, the same product may be obtained, except that the five colors will
be upon the side which receives the first impression from the cylinders A, B.
It is evident that various other products may be produced by simply varying the
path of the web. For instance, if it be desired to print the web e with only four
colors on one side and one on the other, the web will be led to and between
cylinders A, B and C, D, at the rear of the machine, as before; thence directly to
the cylinders C', D', around cylinder D', to and around roll 5 and the transferrer H,
by which it is transferred to the front of the machine; thence to and between
cylinders A. B, and directly to the cylinders A', B', and out over rolls 3, 4 to the
delivery mechanism.
If three colours on one side and one on the other of web e be desired, the web,
printed and perfected by the cylinders A, B, and C, D, will be led, at the rear of
the machine, to and around the web reverser and transferrer H, and thence, at the
front of the machine, directly to the web reverser M, and to cylinders C, D,
and C, D, and out as above described; or the reversal by the reverser M may be
oinitted, and the web led from the web reverser and transferrer H directly to the
cylinders C, D and C¹, D'.

page_text: If a web printed in four colors on one side only be desired, the web, at the rear
of the machine, may be led from cylinders A, B, around the cylinder B, to the
reverser M, thence to the cylinders C; D, thence about the web reverser and
transferrer H, and to the front ends of the cylinders C, D and C', D¹.
In Figures 11 to 14, there is shown a modification employing two perfecting
mechanisins of the same kind, as shewn in Figures 7 to 10, in combination with
two web-reversers and transferrers, the construction being shown in these figures
as printing and delivering, associated together, two webs of less than full width,
the web being printed with four colors on one side and one on the other, and the
web y with three colors on one side only.
The paths of the webs in this construction are as follows:-
:-
The web is led to the type and impression cylinders A, B, and C, D, at the
rear of the machine, as previously described, thus being perfected; thence to the
cylinders C, D, and over the conducting roll 9 and web reverser and transferrer P,
by which the web is reversed, and transferred to the front of the machine; thence
about the impression cylinder D', and under the conducting rolls 30 31 to
cylinders A, B; thence to cylinders A', B', and out over the roll 32 to the delivery
mechanism F, printed with four colors on one side and one on the other.
The web y is led to the cylinders A', B' at the rear of the machine, thence
around the cylinder B', over the reverser and transferrer O, by which the web is
reversed and transferred to the front of the machine; thence over the conducting
roll 33 to the cylinders C, D, and C', D', and out, under rolls 3, 4, to the delivery
nechanism F, printed in three colors on one side only, and associated with the web .c.
If two webs, each printed in three colors on one side and one on the other, are
desired, the web will be led to the cylinders A, B and C, D, and perfected
thereby thence led to the cylinder C¹, D¹; then reversed and transferred to the
front of the machine by the reverser and transferrer P, and led about the
impression cylinder B, and between it and cylinder A'. The web y will be led to
the cylinders A', B' at the rear of the machine, around the cylinder B' to the
reverser and transferrer O; thence to cylinders A, B, and C, D and C¹, D' at
the front of the machine, and out, associated with the web c, as before.
It will be understood that, in the production of all the products described,
the webs may be led to the opposite ends of the cylinders from those stated,
and that the description of the webs, as led to the rear or front, is only for
convenience.
Many other constructions embodying the invention may readily be devised by
those skilled in the art, such constructions being varied in accordance with the
result desired. It will be understood, therefore, that the invention is not to be
limited to any of the specific arrangements shown, nor to the specific form of any
of the printing and perfecting mechanisms, or of the web-controlling devices
combined therewith, but that the form and arrangements of the parts may be
varied widely, without departing from the invention.
It is evident that the web-controlling devices may readily be located as shown,
SO as not to interfere with the lead of the web in perfecting, enabling the
construction to be used for web-perfecting or color printing, without other change
than the lead of the web, but it will be understood that this is not absolutely
essential, but that the invention may be embodied in a construction in which
the web-controlling devices must be removed or thrown out of position for web
perfecting.
It will be understood that the printing mechanism embodying the first part of
the invention may form an independent machine, or may be combined with
other web-printing mechanisms to form a machine printing from a plurality of
webs, in which case the mechanism may be used for producing a colored
printed supplement, or for perfecting a full width web to be associated with the
inain web..
It will be understood, also, that the web-perfecting mechanisms combined with
web controlling devices, to embody the second part of the invention, may form

page_text: independent machines, or may be combined in a single machine printing from a
plurality of webs, as shown.
"
The mechanisms shown are adapted to perfect double-width webs, or to print in
colors a single width web, and it will be understood that the terms "half width
and "less than full width " used herein, refer not to the size of a page, but to the
capacity of the printing mechanism, and the invention may be embodied in
machines printing webs of any width, according to the product desired.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed (as communicated to me
from abroad), I declare that what I claim is :-
:-
