Improvements in or relating to Printing Machinery.
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 :-
The object of the present invention is to provide an improved multiple web-
printing machine, and especially to provide a three-web machine of compact and
convenient form, securing convenient access to the different printing mechanisms
for the various purposes required in web-printing, and with the webs leaving the
printing mechanisms in convenient position for subsequent handling by delivery
mechanisms of different forms, in accordance with the form of the product or
products, and point or points of delivery desired.
As the invention will be best understood from a full description of a construction
embodying the same, all further preliminary description will be omitted, and such a
description be now given in connection with the accompanying drawings forming a
part of this Specification, and showing a multiple web-printing press embodying all
the features of the invention in the preferred form, and certain modifications in the
delivery mechanism, and the features forming the invention will then be specifically
pointed out in the claims.
In the drawings,
Fig. 1 is a diagrammatic side elevation of the complete press, with a double width
two-product main delivery, and showing in dotted lines the lead of the web or webs
to an auxiliary delivery.
Fig. 2 is a diagrammatic section inside the frame, showing the lead of all the
webs to the main delivery.
Fig. 3 is a view similar to Fig. 2, showing a modified lead of the webs.
Fig. 4 is a plan view, showing the same lead as in Figs. 2 or 3.
Figs. 5 and 6 are respectively a plan and end elevation, showing in diagram the
lead of the top web to the side auxiliary delivery, as in dotted lines in Fig. 1.
Fig. 7 is a plan view showing in diagram the lead of the top web to an auxiliary
delivery at the end of the press.
Figs. 8 and 9 are respectively an end and side elevation, also in diagram,
showing the lead of the top web to an auxiliary delivery above one side of the
main delivery.
Referring to said drawings, the printing machine consists essentially of three
web-printing mechanisms, two of which are placed in the lower part of the
machine, and arranged in line, and the other is supported above these two lower
mechanisms. In the form shown, each of the printing mechanisms has two pairs of
type and impression cylinders, the lower front mechanism having the pairs of type
and impression cylinders A B and C D, the lower rear mechanism the pairs of type.
and impression cylinders A¹ B' and C₁ D', and the top mechanism the pairs of
type and impression cylinders A' B2 and C2 D², the type cylinders of these respective
printing mechanisms being provided respectively with the inking mechanisms E, E¹, E³,
which may be of any suitable form.

page_text: In order to bring the two lower printing mechanisms close together, and at the
same time secure convenient access thereto for application and removal of plates &c.,
neither of the web rolls is placed between them, but the lower rolls XX', from which
the webs and c¹ are led, are preferably placed respectively outside their printing
mechanisms, and, as shown, above the floor line of the press, the third web roll X³,
from which the web a² is led to the top printing mechanism, being preferably mounted,
as shown, above and in front of its printing mechanism, and in line with the web
roll X. It will be understood, however, that the position of these rolls may be
varied, but the arrangement shown secures a short lead, and forms a very compact
and convenient construction.
To make the construction as compact as possible, and secure more convenient
access to the cylinders, the successive type cylinders of the two lower mechanisms
are arranged one above the other, so as to reduce the floor space required, and the
successive type cylinders of the top printing mechanism are arranged in substantially
the same horizontal plane, so as to reduce the height of the press, this enabling the
three mechanisms to be mounted very compactly, as shown, with the lower cylinders
of the two lower mechanisms quite close together, with convenient access between
them, and the top mechanism extending above the lower mechanisms and the space
between them, the upper cylinders of the lower mechanisms preferably being
separated farther than their base cylinders, so as to afford space for dropping the
impression cylinders of the top mechanism, this securing also convenient access
from above to the upper type cylinders of the two lower mechanisms at the opposite
ends of the
press.
The two lower printing mechanisms are shown as driven from the main driving
shaft S at the base of the machine, through bevel gears 10 and series of inter-
mediates 11, and the top printing mechanism is shown as driven from the first
impression cylinder B of the lower front mechanism through an intermediate 12.
In order that the top printing mechanism may be run with either of the
lower mechanisms, however, so that two printing mechanisms may be run in
case of stoppage of either of the lower mechanisms, this intermediate 12 is
removable, and a stud 12 is provided, upon which the intermediate 12 may be
placed to drive the top printing mechanism from the second impression roll D' of
the lower rear printing mechanism, and by removing the intermediate 12, the two
lower mechanisms may be driven without driving the top mechanisın.
The lead of the three webs through the feeding mechanism requires no
description, as it is obvious from the drawings, it being understood that rolls 1 are
simple guide rolls, over which the webs are led. The webs may be led as shown
in Fig. 2, so as to have the first impression on the upper side, as the webs pass to
the delivery mechanism, or, as in Fig. 3, with the first impression on the under
side, only the simple change in lead shown being required.
It will be seen that this arrangement of printing mechanism provides a very low,
compact, and convenient construction of three-web perfecting press, in which all
the type cylinders are readily accessible for inspection and handling of plates; the
threading of each of the webs is convenient, and all the parts of the machine in
convenient position; while the lead of the webs to the printing mechanisms, and
from the latter, to bring them together, is very short and direct.
With this printing mechanism it is evident that delivery mechanism of various
forms may be conveniently used. Thus, the three double-width webs a, a, a², may
be led from the respective printing mechanisms to a delivery mechanism, consisting
of two longitudinal folders F, placed side by side, as shown in Figs. 1 to 4, a
slitter 13 being used by which the webs are slit centrally, so that three single-width
webs thus pass to each longitudinal folder F, and to each delivery G, equal products
thus being delivered at opposite sides of the machine.
It is desirable, however, that means should be provided for securing three
products, and that one or more of the webs may be delivered with the two halves
of the webs at opposite sides of the press, associated one upon the other and for
this purpose a simple and convenient construction is provided, well adapted for the

page_text: different products desired, in which the main delivery mechanism, by which the
three webs, or one or more of them, may be delivered on a straight run, and
without association of the two halves one upon the other, is combined with an
auxiliary delivery, by which one or more of the webs may be delivered with the
two halves associated one upon the other. By this construction, a great variety of
products may be secured, and three eight-page papers produced from webs of the
proper width, of which papers two consist of four pages from each of two webs,
and the third being from a single web. The construction and location of the
auxiliary delivery will depend somewhat upon the result desired, and upon the
floor space, but in all these constructions, a transferrer, lying outside the path to
the main delivery, and preferably above the latter, will be used, by which one or
more of the webs, after being slit longitudinally, may have its or their sections
transferred, so as to lie one upon the other.
In Figs. 5 and 6, a transferrer above the main delivery, consisting, in the form
shown, of turning bars 14, is combined with a delivery at one side of the main
delivery, a longitudinal folder F2 and delivery mechanism G2 being used, by which
the product will be delivered end wise of the press, and opposite the main delivery,
a slitter 13 being used in connection with the transferrer, and each of the sections
being turned at right angles by one of the turning bars, and the right-hand section
brought under the left-hand section, the lead of the web or webs from the printing
mechanism being shown in dotted lines in Fig. 1.
In Fig. 7 is shown a construction which will be found desirable when the floor
space widthwise of the press is limited, in which the auxiliary folder F' and
delivery G2 is placed rearward of, and in line with, one side of the press, one section
of the slit web or webs passing directly to the auxiliary mechanism, and the other
section being carried about both turning bars of the transferrer, and brought on top
of the other section, the transferrer 14 being in the same position as in Figs. 1, 5,
and 6.
In Figs. 8 and 9, a construction is shown which is well adapted for use when
additional floor space for the auxiliary mechanism cannot conveniently be secured.
In this construction, the auxiliary delivery is placed above one side of the main
delivery mechanism, and one section of the web or webs led directly thereto, while
the other section is carried above both turning bars of the transferrer, and brought
on top of the first section, the product being delivered at the side of the press,
above one of the products from the main delivery mechanism. In this construction,
the transferrer 14 is raised to a greater height above the main delivery, and moved
forward from the position shown in the other figures.
It will be understood by those skilled in the art, that the deliveries G G2 may
be of any suitable form, and that various other devices for securing a variety of
products, such as additional slitters, and pasting or stapling mechanisms, may be
added to the construction shown.

tion and in what manner the same is to be performed, as communicated to me from
