the Office of the Commissioners of Patents on the 7th February 1883.
WALTER WILLIAM COLLEY of Camberwell in the County of Surrey, "IMPROVE-
MENTS IN PRINTING MACHINERY."
This Invention has for its object improvements in perfecting printing machinery
for printing newspapers and other periodicals from two or more rolls or continuous
webs of paper, and the Invention consists essentially in an improved combination
and arrangement of the cylinders, formes, and adjuncts and in the mode of running
the paper through the machine, whereby two continuous webs are simultaneously
printed each on one side from the same set of type on one type cylinder and are
concurrently therewith simultaneously perfected or printed on their other sides
from two other type cylinders carrying identically similar formes. The Invention
further consists in an improved mechanism for gathering the printed sheets and
delivering them in parcels alternately of 12 and 14 printed sheets, one quire or 26
sheets being thus delivered by two successive drops of the flyer.
In order to perfect two continuous webs of paper at once, I employ six cylinders
in two sets of three each arranged above one another, the first set consisting of a
type cylinder between two impression cylinders, printing, say the outer formes, on
the two sheets from the same type, and the second set consisting of one impression
cylinder between two type cylinders bearing identical formes, and respectively
printing, say the inner formes on the two sheets. The type cylinder of the first set
is provided with two sets of inking apparatus and is inked twice in each revolution.
The other two type cylinders have each one set of inking apparatus.
improvement in the several inking apparatus (which are similar for all the type
cylinders) consists in making the transfer of the ink from the ductor roller to the
inking drum continuous instead of intermittent by employing instead of a
vibrating roller a roller resting upon and between the ductor roller and the inking
An

page_text: drum and rotated by frictional contact therewith the ductor roller and inking drum
being driven at the same surface speed in the same direction by suitable gearing.
Should the space available prevent the employment of a single inking drum of
sufficiently large diameter I may employ two small drums placed one after the
other with a transferring roller resting on and between the two and rotated by
frictional contact therewith each drum being provided with one or more
distributing rollers.
The webs of paper are passed through the machine in opposite directions, that is
to say, the one from a roll mounted above is passed through between the type
cylinder and the upper impression cylinder of the first set of cylinders and then
between the impression cylinder and the upper type cylinder of the second set
whereby it is perfected whilst the web from the other roll mounted at the lower
part of the machine is passed first between the impression and lower type cylinder
of the second set and is then perfected by passing between the type and lower
impression cylinder of the first set, the printing of the two webs going on
concurrently. If desired to print three webs of paper at once this may be done by
adding another type and another blanket cylinder and so on in proportion. The
webs having been thus printed upon both sides are then run together between the
same pair of perforating or cutting drums by which the two webs are together
perforated across their width at proper intervals. The webs pass on between sets
of tapes where they are completly severed at the lines of perforation into sheets
which are conveyed in pairs (one from the top and one from the bottom web) to a
gathering drum around whose periphery the pair of sheets are lapped, the following
pairs of sheets being superposed in succession upon the first pair at each revolution
of the gathering drum until the desired number has been collected together. This
drum is constructed of a number of rings placed side by side upon the same axis
with intervals between corresponding to the flyer arms whose ends are received
therein at the proper times whereupon the sheets gathered upon the drum pass off
the drum and in front of the flyer for delivery. The flyer is worked by a cam so
constructed as to raise and lower the fyer at intervals at alternately different
durations corresponding respectively to six and seven revolutions of the gathering
drum so that packets of 12 and 14 sheets are delivered alternately by the flyer and
two successive deliveries together produce 26 sheets or one quire.

by the said Walter William Colley in the Great Seal Patent Office on the

WALTER WILLIAM COLLEY of Camberwell in the County of Surrey "IMPROVE-
MENTS IN PRINTING MACHINERY "
This Invention has for its object improvements in perfecting printing machinery
for printing newspapers and other periodicals from two or more rolls or continuous
webs of paper, and the Invention consists essentially in an improved combination
and arrangement of the cylinders, formes, and adjuncts and in the mode of running
the paper through the machine, whereby two continuous webs are simultaneously
printed each on one side from the same set of type on one type cylinder and are,
concurrently therewith, simultaneously perfected or printed on their other sides
from two other type cylinders carrying identically similar formes. The invention
further consists in an improved mechanism for gathering the printed sheets and
delivering them in parcels alternately of 12 and 14 printed sheets, one quire or
26 sheets being thus delivered by two successive drops of the flyer.
In order that the Invention may be more readily understood I have illustrated
it in the accompanying drawings and will proceed to describe it with reference
thereto.
Figure 1 is a side elevation of a printing machine as constructed and arranged
according to my Invention for perfecting two webs of paper at once.
Figure 2 is
an elevation of the opposite side showing the gearing for the various cylinders.
The machine comprises six cylinders in two sets of three each arranged above
one another, the first set consisting of a type cylinder A between two impression
cylinders B B and the second set consisting of one impression cylinder "B"
between two type cylinders A¹ A2 bearing identical formes. The first cylinder
A prints (say the outer forme) on the one side of each of the two webs both webs
being printed from the same type, and the two cylinders A' A³ of the second set
print (say the inner formes) on the other sides of the two webs respectively.
type cylinder A of the first set is provided with two sets of inking apparatus and
prints twice in each revolution once on each sheet. The other two type cylinders
AA2 have each one set of inking apparatus.
The
The webs of paper c c¹ are passed through the machine in opposite directions,
that is to say, the one c from a roll C mounted above is passed through between
the type cylinder A and the upper impression cylinder B of the first set of cylinders
and then between the impression cylinder B² and the upper type cylinder A¹ of
the second set whereby it is perfected, at the same time the web c¹ from the other
roll C mounted at the lower part of the machine is passed first between the
impression cylinder B2 and lower type cylinder A² of the second set and is then
perfected by passing between the type cylinder A and lower impression cylinder B¹
of the first set, the printing of the two webs going on concurrently.
The webs having been thus printed upon both sides are then run together
between the same pair of perforating or cutting drums D by which the two webs
care together perforated across their width at proper intervals.
The webs pass
on between sets of tapes E E¹ running at a greater speed than the perforated webs
of paper so that the latter are completely severed at the lines of perforation into
sheets which are conveyed in pairs (one from the top and one from the bottom web)
o a gathering drum F around whose periphery the pair of sheets are lapped by
he tapes E and other tapes E² beneath the drum. The following pairs of sheets
re superposed in succession upon the first pair at each revolution of the gathering

page_text: drum F until the desired number has been collected together.
This drum is con-
structed of a number of rings placed side by side upon the same axis, with intervals
between corresponding to the flyer arms G whose ends are received therein at the
proper times, whereupon the sheets gathered upon the drum pass off the drums
and in front of the flyer for delivery. The flyer is worked by a cam H of such
form as to raise and lower the flyer at intervals of unequal duration alternating
and corresponding respectively to six and seven revolutions of the gathering drum
F so that packets of 12 and 14 sheets are delivered alternately by the flyer and
two successive deliveries together produce 26 sheets or one quire.
The several inking apparatus are similar for all the type cylinders and the
transfer of the ink from the ductor roller a to the inking drum b is made con-
tinuous instead of intermittent by employing, instead of a vibrating roller, a roller d
resting upon and between the ductor roller a and the inking drum b and rotated
by frictional contact therewith, the ductor roller and inking drum being driven at
Should the
the same surface speed in the same direction by suitable gearing.
space available between the webs of paper prevent the employment of a single
inking drum of sufficiently large diameter I may employ two small drums bb'
placed one after the other, as shown, with a transferring roller d' resting on and
between the two and rotated by frictional contact therewith each drum being
provided with one or more distributing rollers e. f are the inking rollers. The
distributing rollers e receive the usual endwise motion from a cam g and levers h.
The rollers and drums a b b' are geared (see Figure 2) by their wheels a' b² b² and
intermediate wheels with the type cylinder from which they are driven as
shown.
Having described the nature of the said Invention and the manner of performing
the same I declare that what I claim as the Invention to be protected by the
hereinbefore in part recited Letters Patent is :-
1st The combination, and arrangement, of rotary printing apparatus whereby
two continuous webs running in opposite directions are simultaneously printed each
on one side by the same set of type on one type cylinder and are concurrently
therewith simultaneously perfected or printed on their other sides by two other
type cylinders substantially as shown and described.
2nd The construction, combination, and arrangement of gathering and delivery
mechanism whereby, pairs of sheets are detached, gathered on a drum, and delivered
in alternately unequal numbers substantially as shown and described.
In witness whereof I the said Walter William Colley have hereunto set my
hand and seal this third day of August in the year of our Lord One thousand eight
hundred and eighty three.
