Improvements relating to Web Printing Machines.
I PHILIP ARTHUR 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 multi-web printing
machine of such compact and convenient form as not only to provide ready access
to the various printing mechanisms, but enable the webs to be so disposed with
respect to said mechanisms as not to interfere with the movements of the attendants
about and through the machine, in manipulating the forms thereof, adjusting the
inking apparatus thereof, threading the webs there-through, and obtaining the
shortest lead of each web from positions outside of the printing machines, through
the respective printing machines, to the delivery mechanism.
The invention consists in various combinations and arrangements of the printing
mechanisms, web guides, and delivery apparatus, whereby the aforesaid objects are
attained, all of which are so specific in their character, that the nature thereof will
be fully comprehended from the following specification.
Exemplifications of the invention are illustrated in the accompanying drawings,
in which
Fig. 1 is a side elevation of a quadruplex machine;
Fig. 2 being an end elevation of the delivery apparatus thereof.
Figs. 3 and 4 are similar views of a like machine, in which the rolls of paper are
in slightly different positions.
Figs. 5 and 6 are also similar views of a like machine, in which the rolls of paper
are in slightly different positions.
In these drawings all gearing is dispensed with, and many parts common to the
art are omitted, in order to render the illustrations perspicuous. The form-
bearing cylinders are provided with diametrical lines, to indicate their character.
The impression cylinders of each are left plain for a like purpose, and the inking
cylinders are marked I to designate them, and like indicating characters of
reference are used in the several drawings, to indicate correspondence of parts.
The essentials of a machine so extensive in its mechanism as is necessarily
involved where four webs of paper are simultaneously printed and deliveret, are
not only that said mechanism shall be arranged relatively so as to occupy the least
possible space, owing to their use in establishments usually located in cities where
the ground space is of the most expensive character, or the confines of the printing
departments of which have been constructed for smaller machines, and hence are
not only fixed, but of limited dimensions, especially in height; but that there shall
be in and about the machine a provision made by Euch disposition of the parts of
the mechanism as will enable the operators to have ready access to the form
cylinders for applying the plates thereto, to the inking mechanisms for constantly
controlling their action, so that perfect inking and resulting printing may be con-
tinuously effected, and accces conveniently had to the paths of travel of the webs,
that they may be readily threaded. There must also be such a run of the webs

page_text: that they shall not interfere with this provision for access to such parts of the
mechanism os require it, all of which is provided for by these improvement.
Each perfecting printing mechanism, of which there are four, A, B, C, D, in
addition to the inking apparatuses, consists of form cylinders FFFF, and printing
cylinders P1, P, P, P. Ench of the printing mechanisms is arranged in the same
vertical plane; the printing cylinders of all of the mechanisms have their axes
parallel; and the printing mechanisms A, B, as well as the printing mechanisms C, D,
are separated apart from each other to such a distance as will afford, between
them, openings or passage-ways O, S for the movements of the attendants and
operators, and the printing mechanisms C, D, are elevated above the printing
mechanisms A B to the extent required to provide for access between the upper
and lower pairs of printing mechanisms for the webs, and yet present an entire
machine that shall accommodate itself to a limited space.
The web of paper 1 is guided by a roller 10, to and around the first impression
cylinder P, thus receiving an imprint upon one side from the form cylinder
and thence passes around the second impression cylinder P, which bears it into
contact with the second forin cylinder F, by which it is imprinted on its second
side, being thus perfected. This perfected web thence passes outward over guiding
rollers 13, 14, to and over a common guiding roller 100, from which it passes to the
delivery mechanism.
The web of paper 2 is guided over a roller 20 to and around the first
impression cylinder P, thus receiving an imprint upon one side from the form
cylinder F, and thence passes around the second impression cylinder P3,
which bears it into contact with the second form cylinder F, by which it is
imprinted on its second side, being thus perfected. This perfected web thence
passes outward over guiding rollers 22, 23, and 24, to the common guiding roller 100,
from which it passes to the delivery mechanisun.
The web of paper 3 is guided by means of rollers 30, 31 (omitted in Fig. 1),
32, 33, 34, 35, to aud around the first impression cylinder P3, thus receiving au
imprint upon one side from the form cylinder F, and thence passes around the
second impression cylinder P, which bears it into contact with the second form
cylinder F, by which it is imprinted on its second side,-being thus perfected.
This perfected web thence passes outward over guiding roller 36, to and over a
common delivery roller 101, from which it passes to the delivery mechanism.
The web of paper 4 is guided by means of rollers 40, 41, to and around the first
impression cylinder P, thus receiving an imprint upon one side from the forin
cylinder F, and thence passes around the second impression cylinder P, which bears
it into contact with the second form cylinder F, by which it is imprinted on its
second side, being thus perfected. This perfected web thence passes outward over
guiding rollers 42, 43, to and over a common delivery roller 101, from which it
passes to the delivery mechanism.
There are provided for the run of the webs of the printing machines C, D,
auxiliary guiding rollers 50, 51, 60, 61, by which said webs 3, 4, are respectively
guided to and over the common delivery or guiding roller 100, at which the webs
are associated, or brought into a common path of travel.
The delivery mechanism, which is external to the printing mechanisms, consists
of longitudinal folders, designated, in a general sense, 15, 16, 17, 18, said folders
being of any of the present well-known forms, as shown, consisting of bars arranged
to constitute a triangular internal former, in passing over which, the paper has its
sides brought together at, and is folded longitudinally in passing between external
turners 5, 6. Thus doubled, or folded longitudinally, it is entered between
cylinders 7, 8, which are provided with cutting mechanisms to sever it into sheet
lengths, and the latter with carrying means and a folding blade, whereby the
severed sheets are delivered, once folded, through the rollers 90, 91, on tapes 161,
or a table. The cylinders 7, 8, represent in part such a delivery mechanism
substantially as is shown in British Patent No. 9335 of 1891, but of course any
other delivery apparatus than the one shown may be employed, so long as it is

page_text: capacitated to receive the paper in the web-form from rollers, as 109, 101, convert
the same into short lengths or sheets, and deliver the latter in piles, folded or flat,.
ns may be desired.
The construction and arrangement of the mechanisms of these printing machines,.
enables the rolled webs to be so positioned outside of the mechanisms, that their
carrying shafts may be readily placed in their bearings, without interfering with
access to the mechanisms, and each web is so guided or threaded through the
mechanisms, that a clear space is provided for the convenient movements of the
attendants, to and about the mechanisms of each pross.
Having now particularly described and ascertained the nature of said invon-.
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. The combination with two web-printing machines arranged in line in one.
plane, with their cylinders parallel, two printing machines arranged in line
in a higher plane over said first mentioned printing machines, and having their
oylinders parallel with those of the lower printing machines, and delivery
mechanism external to, and aligned with said printing machines, of means for
mounting all the web rolls outside of the printing machines, and outside of the
paths of the webs leading from the several rolls thereof, of guides supporting the
webs and causing the same to run directly onward to and through their respective
printing machines and to said delivery mechanism, whereby the webs are caused to
travel in plaues that leave clear spaces between the machines for the movements of
the attendants, substantially as described.
2. The combination with two web printing machines arranged in line in oue-
plane, with their cylinders parallel, of two web printing machines in line in a
higher plane over the two first mentioned printing machines, and having their
cylinders parallel with those of the lower printing machines, of means arranged for
guiding two of the webs horizontally through the mechanisins immediately beneath
the two upper printing machines, and one web horizontally above the two upper-
printing machines, whereby access to the mechanisms and webs is unobstructed,.
substantially as described.
3. The combination with two web printing machines arranged in line in one
plane with their cylinders parallel, two web-printing machines arranged in line in
a higher plane over the first mentioned printing machines, aud having their
cylinders parallel with each other, and with those of the lower printing machines,.
of web guides for carrying the printed webs from the four printing machines in
sets of two webs,.ench set being guided outward for delivery in plaues respectively
above the printing machines nearest the delivery mechanism, whereby access to.
the form cylinders and inking mechanisms of each is provided for, substantially as
described.
4. The combination with two web printing machines arranged in line in one
plane with their cylinders parallel, two web printing machines arranged in line in
a higher plane over the first mentioned printing machines, and having their
oylinders parallel with each other and with those of the lower printing machines,.
of web guides for carrying the webs through the machines, whereby two of the
webs are carried immediately beneath the upper printing machines, and one web is
carried above the two upper priuting machines, and web guides whereby the four
printed webs are carried to the delivery mechanisins, in sets of two, in planes.
respectively above the printing machines nearest the delivery-mechanism, whereby
access to all parts of the mechanisms is provided for, substantially as described.
5. The combination with four web-printing machines arranged in vertical and
horizontal pairs, the mechanism of companion machines being separated to afford
convenient access to the parts of all the machines, and delivery mechanism external
to, and aligned with, said printing machines, of guides whereby the webs running
through the machines are supported and travel in planes that leave clear spaces.
between the machiues for the movements of the attendants, and guides adjacent.

page_text: thereto, whereby all of the webs may be led directly to one set of delivery
mechanism, or the webs from two of the printing machines may be led directly to
one set of the delivery mechanisms, and the two webs from the other two printing
machines may be led directly to the other set of delivery mechanisms, substantially
as described.
