Improvements in Web Printing Machines and Sheet Collecting and
Delivery Mechanisms therefor.
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 the present invention is to provide an improved printing machine
capable of delivering a variety of products with slight adjustments, and especially
to provide a high capacity machine of compact and convenient form, combining with
a web printing mechanism, a plurality of delivery mechanisms, to either of which
the web may be led from the printing mechanism.
In web printing machines of that class in which the web is printed at one end of
type and impression cylinders, and then reversed by a web turner, and perfected at
the opposite end of the cylinders, and then delivered to the delivery mechanism, the
delivery mechanism need occupy but one-half the width of the machine, as the web
handled by it has a width of only one half the length of the type and impression
cylinders.
By this invention, the capacity of such machines for producing different products
is increased, without increasing the floor space of the machine, by combining with
the printing mechanism two delivery mechanisms placed side by side, and each
capacitated to handle a sheet of the full width produced by the printing mechanism,
and arranging the printing mechanism so that a web may be perfected at either
end of the cylinders as desired, so as to be delivered by either of the delivery
mechanisms.
The delivery mechanisms thus combined with the printing mechanism may be of
any form desired, in accordance with the products to be produced, so that the papers
printed in such machines may be delivered open full size, or folded to the form
desired. The flat delivery may be added to machines of the general construction,
and is preferably made a collecting delivery, to collect a number of sheets from the
web, and deliver them flat by a fly.
This invention may be embodied in a machine having the general construction
shewn and described in the Specification of a Patent granted to the present Applicant,
dated June 2nd 1891, No. 9335, to which is applied a collecting flot delivery located
in the space beside the longitudinal folder, and above the devices for giving the second
longitudinal fold, the printing mechanism being arranged so that the web may be
perfected respectively at either end of the type and impression cylinders, as
preferred
This machine may be used with or without any suitable offsetting devices.
By this invention, a simple and efficient delivery mechanism is also provided, by
which a series of sheets may be collected from the web, and delivered without
folding at a high rate of speed, or in which the collecting cylinder delivers directly
to a fly, the collecting cylinder forming one of a pair of cutting and collecting
cylinders, the cooperating cutting cylinder, or an independent feeding roll, advancing
the sheets after they are released by the sheet-holding pins.
The delivery at high rates of speed is secured by providing the collecting
cylinder with strippers co-acting with the sheet holding pins to throw the sheets off

page_text: .
the pins and away from the cylinder a sufficient distance to ensure their reception
by the fly and by a collecting cylinder employing pins and strippers moving together
in delivering the sheets from the cylinder...
The web roll may be led to either end of the type and impression cylinders, but
preferably to the folding delivery side of the machine, and the web passed beneath
the type and impression cylinders, to be printed upon one side, thence over one end
of a conducting roll composed of two independent sleeves, downward around a
turner, returning upward between the cylindels at the flat delivery side of the
machine, thus perfecting the web.
An offset web may be used on the last or perfecting impression, and in order to
shift the offset rolls from one side, of the machine to the other they are mounted
upon a carriage, the offset web being led, to and between the web printed and the
impression cylinder, returning around a conducting roll to a roll upon which it is
wound. This roll is rotated to feed the offset web by two roligh-faced friction 'rolls,
upon which the offset roll rests.
A simple flat non-collecting delivery thay be used, but it is préférable-to
collect the sheets from the web by a collecting cylinder, and deliver directly
to a fly.
The collecting cylinder preferably consists of a series of dises, mounted on a shaft,
with bars extending the full length of the cylinder,. and between the discs, so as to
form a cutting groove co-acting with a knife carried by the cutting cylinder to sever
the sheets.
"
:
Between the discs are mounted the sheet holding pins and strippers. The pins
are mounted on a shaft carrying at one end a crank arm connected. by a link to
another crank arm on the shaft which carries the stripper. The stripper shaft
carries, at one end, a crank arm provided with a bowl which runs in a cam plate
mounted to rotate on the shaft carrying the collecting cylinder.
As the strippers are thrown outward to carry the sheets off the pins, the pins are.
simultaneously rocked upward towards the strippers, following the motion of the
sheets as they are pressed off the cylinders by the stripper, and permitting them to
be readily removed, without danger of tearing the sheets.
In front of the collecting cylinder, and above the fly, a feeding roll formed by a
series of discs adjustable, longitudinally, on their shaft, is preferably mounted; this
roll is held under spring tension against the collecting cylinder, and coacts with the
collecting cylinder to feed the sheets forward after they are received from the pins.
Or the cutting cylinder may be constructed to co-act with the collecting cylinder
in feeding the sheets:
The use of the spring!pressed feeding rolls secures the proper feeding of a large
number of sheets:
The fly consists of the usual series of fingers mounted on a rock shaft; the shaft
is rocked to return; the 'fly. against. the spring tension by a rocking lever provided
withib, bowl which runs upon a rotating cam. Short stationary guides may, in some
cases, be provided between the collecting cylinder and the fly...
The driving of the parts is so timed,, that the collecting cylinder makes two
rotations to each rotation of the impression cylinder, and the fly makes one movement
to each four rotations of the collecting, cylinder, two sheets being sprinted_at_each
rotation of the impression cylinder, so that four sheets are collected and delivered
together:
The pins and strippers are actuated once to each four rotations of the collecting
cylinder, the operating cam being driven at a higher rate of speed than-the
collecting cylinder.
i.
The number of sheets collected to each delivery may be varied as desired, by
changing the timing of the parts.
While the invention is especially adapted for application in connection with web
perfecting mechanisms employing a single type cylinder and perfecting a web of a
width less than the length of the type cylinder, it is applicable also in connection
with other printing mechanisms, and although designed for web printing machines,

page_text: the invention may be applied also to machines in which the paper is fed to the
printing mechanism in the form of sheets.

COMPLETE SPECIFICATION.
Improvements in Web Printing Machines and Sheet Collecting and
Delivery Mechanisms therefor.
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 printing machine
capable of delivering a variety of products with slight adjustments, and especially
to provide a high capacity machine, of compact and convenient form, combining
with a web printing mechanism a plurality of delivery mechanisms, to either of
which the web may be led from the printing mechanism.
In web printing machines of that class in which the web is printed at one end
of type and impression cylinders, and then reversed by a web turber, and perfected
at the opposite end of the cylinders, and then delivered to the delivery mechanism,
the delivery mechanism need occupy but one half the width of the machine, as the
web handled by it has a width of only one half the length of the type and impression
cylinders.
"!
An improved construction is provided by which the capacity of such machines
for producing different products is increased, without increasing the floor space of
the machine, by combining with the printing mechanism, two delivery mechanisms
placed side by side, and each capacitated to handle a sheet of the full width.
produced by the printing mechanism, and arranging the printing mechanism so that
a web may be perfected at either end of the cylinders, as desired, so as to be
delivered by either of the delivery mechanisms.
The delivery mechanisms thus combined with the printing mechanism may be of
any form desired, in accordance with the products to be produced, and the invention
includes broadly such a combination of delivery mechanisms with a printing
mechanism, independent of the special form of the printing or delivering mechanisms
employed, but an especially desirable result is attained by thus combining with the
printing mechanism, a flat and folding delivery, so that the papers may be delivered
open full size, or folded to the form desired. The flat delivery may be added to
machines of the general construction, now common, employing a folding delivery
on one side of the machine, in combination with a perfecting printing mechanism,
there being ample space for this purpose at the delivery end within the frame of
the machine, and this flat delivery is preferably made a collecting delivery, and
capacitated to collect a number of sheets from the web, and deliver them flat, as by
& fly or equivalent device It is evident, however, that this part of the invention
may be applied to machines of widely different construction, and that it is not
dependent upon the variety of products produced by the folding mechanism.
In the accompanying drawings, however, there is shown, for the purpose of
illustration, a machine embodying the invention, capacitated to produce a very
large variety of products by the folding mechanism, or to collect and deliver a
plurality of sheets flat, as desired, the machine being of the general construction
shown and described in the Specification of a Patent granted to the present appli-
cant, and dated June 2, 1891, No. 9335, to which is applied 'a'collecting flat delivery
located in the space beside the longitudinal folder, and above the devices for giving
the second longitudinal fold, the printing mechanism being arranged so that the
تاره است.

page_text: web may be perfected respectively at either end of the type and impressión
cylinders, as preferred.
The machine may be used with any suitable offsetting devices, or without the
same, but it is preferable to use offset devices on the last or perfecting impression,
and there is combined with the printing mechanism arranged for the change in the
lead of the web, as above described, offset devices which may be shifted to either
side of the machine, in accordance with the end of the type and impression
cylinders at which the web is perfected, and this construction forms a part of the
· present.invention.
By this invention, a simple and efficient delivery mechanism is also provided, by
which a series of sheets may be collected from the web, and delivered without
folding at a high rate of speed, or in which the collecting cylinder delivers directly
to a fly, or equivalent final delivery devices.
In the construction embodying this part of the invention, the collecting cylinder
forms one of a pair of cutting and collecting cylinders, and the cooperating cutting
cylinder may be so constructed and positioned, as to coact with the collecting
cylinder, to advance the sheets after they are released by the sheet holding pins,
but an independent feeding roll is preferably provided for this purpose, and this.
roll is preferably mounted so as to yield as successive sheets are collected upon the
cylinder, thus securing the proper feed of the sheets irrespective of the increase of
surface speed of the sheets as they are collected upon the cylinder.
.
Certainty in the delivery at high rates of speed is secured by providing the
collecting cylinder with strippers coacting with the sheet-holding pins, to throw
the sheets off the pins, and away from the cylinder a sufficient distance to ensure
their reception by the fly or other devices cooperating with the cylinder, and a
collecting cylinder of an improved construction employing pins and strippers
moving together in delivering the sheets from the cylinder has been devised, and
is preferably used, in which the pins are actuated positively and independent of the
engagement of the pins by the strippers, a certain and smooth action of the parts
being thus secured at a very high rate of speed, and the wear upon the pins and
grippers being reduced, so that this action may be maintained for a long time.
This part of the invention, therefore, consists broadly in a sheet-collecting
cylinder, and devices coacting therewith, to sever sheets from the web, and deliver
them directly to a fly, or equivalent delivery devices, and in various constructions
and combinations of parts in a machine embodying this invention, and in various
improvements of general application in collecting cylinder constructions, whether
delivering directly to final delivery devices, or not, all of which will be fully
described in the following Specification, and pointed out in the claims.
For a full understanding of the invention, a detailed description of the machine
above referred to will now be given in connection with the accompanying drawings
forming a part of this Specification, and the features forming the invention
specifically pointed out in the claims.

Fig. 8 is a detail section taken inside the frame, showing the cutting and
collecting cylinders.
Figs. 9 and 10 are detail broken views of the collecting cylinder.

page_text: Referring to said drawings, it will be seen that the machine, including the
printing mechanism and folding delivery, is of substantially the general construction
shown and described in the Patent above referred to, A being the type cylinder,
B the impression cylinder, C the web turner, D the ink distributing cylinder, E the
web roll from which the web is fed; F the longitudinal folder by which the first
fold of the web is formed; and G the folding delivery fully described in the Patent
above referred to, so as to require no further description here, these devices being
capacitated to produce products varying from a four page paper to one or more
pamphlets of one hundred and twenty eight pages each.
The web roll E may be mounted upon its shaft 10, at either side of the machine,
as desired, so that the web may be led to either end of the type and impression
cylinders, and the roll is preferably provided with the usual tension devices 11,
which also are made adjustable upon their shaft 12, so as to be shifted to either
side of the machine, in accordance with the position of the web roll E.
machine is shown with the web roll at the folding delivery side of the machine, so
that the perfected web is delivered to the flat collecting delivery, and the product
delivered thereby.
The
From the web roll E, the web passes, under the control of the tapes c, d, beneath
the type and impression cylinders A B, at the folding delivery side of the machine,
where it is printed upon one side; thence over one end of the two-part conducting
roll 13, downward around the turner C, returning over the other side of the
turner and the other end of the two-part conducting roll 13, thence downward
around the impression cylinder B, and upward between the cylinders A B, at the
flat delivery side of the machine, all as shown in Fig. 6, the web being thus

perfected, and passing thence over the tension roll 14 to the delivery.
construction differs from that of the Patent referred to, in that the conducting roll 13
is not positively driven, as it is necessary for the direction of rotation of the two
parts, to be changed in accordance with the lead of the web, and this roll is formed
therefore, of two independent sleeves frictionally driven by the web.
This printing mechanism, as above stated, may be used without offset devices, or
It is
any suitable construction of such devices may be combined therewith.
preferable, however, to use an offset web on the last or perfecting impression, and
to enable this offset web to be shifted in accordance with the lead of the web z the
offset rolls are preferably mounted upon a carriage by which they may readily be
shifted to either side of the machine, as desired. In this construction, H is the
carriage in which are supported the offset rolls 15 and 16, these rolls being made
interchangeable, as usual, and the support of the roll 16 from which the offset web
is drawn being provided with the usual adjustable tension devices. The offset web y
is led from the roll 16, about a roll 17, extending across the machine above the
two-part conducting roll 13, then downward between the web and the impression
cylinder, returning around the conducting roll 14, beneath the web, and thence
The roll 15 is

rotated to feed the offset web by two rough-faced friction rolls 19, upon which the
offset roll rests, the roll being mounted in bearings free to move upward as the size
of the roll increases, as usual in such constructions. The carriage H may be held
in position by the screw 20, as shown, or by any other suitable means.
The friction rolls 19 are driven as follows:-
The main shaft of the machine I drives the impression cylinder B through
gears 100, 101, on the main shaft and impression cylinder respectively, and the
main shaft drives the delivery mechanisms through a series of intermediates 102,
which drive the folding delivery through a gear 103 on shaft K, from which move-
ment is transmitted to all the folding devices, as from shaft 123 in the Specification
of the before mentioned Patent. Through these intermediates 102, a shaft Lis
driven by gear 104, and from this shaft all the flat collecting delivery is drive:1.
It will be seen that by shifting one of the intermediates 102 from the position
shown in Fig. 4 to the stud 105, the flat collecting delivery will be thrown out of
operation, and the folding delivery into operation, the machine being shown as

page_text: delivering fit. From one of the intermediates 102, the friction rolla 19. (see Figs. 1
and 6) are driven through a small intermediate 16, which secures the proper
direction, and gears 107 on the rolls.
The flat collecting delivery is mounted upon the frame at the side opposite the
longitudinal folder F, and may be of any suitable form, and it will be understood,
also, that a simple flat non-collecting delivery may be used, if desired. In the
machine shown, however, a flat collecting delivery is illustrated, which is preferably
used, in which sheets are collected from the web by a collecting oylinder, and
delivered directly to a fly, and this collecting mechanism in itself forms a part of
the present invention.
In this construction, M is the collecting cylinder, N. the cutting cylinder coacting
therewith to sever the sheets, and O the fly by which the sheets are delivered from
the collecting cylinder M. The web is shown as led from the impression cylinder B,
under an adjustable tension roll 21, and between spring-pressed feed roll 22, and the
collecting cylinder M, so as to secure the proper feed of the web to be seized by
the pins of the collecting cylinder, but it will be understood that any other suitable
arrangement may be used for this purpose. The collecting cylinder M is cut
away for the pins and the strippers by which the sheets are delivered from the
pins, and preferably consists of a series of discs 23 mounted on a shaft 24, with bars
extending the full length of the cylinder, and between the discs, so as to form a
cutting groove coacting with knife 2 of the cutting cylinder N, to sever the
sheets.
Between the discs 23 are mounted the sheet-holding pins a and strippers.b,
the pins being set at the proper angle to seize and bold the successive sheets, and
the strippers being formed of fingers preferably made of thin rigid metal, and
provided at their outer ends with openings through which the pins extend. The
pins a are mounted on a shaft 3 extending through the discs 23, forming the
collecting cylinder, which shaft carries at one end a crank arm 4, connected by a
link 5 to a crank arm 6 on shaft 7, which carries the strippers b, and is mounted
in the discs 23. The shaft 7 of stripper 6 carries, at one end, a crank arm 8;
provided with a bowl, which runs in a cam plate 25 mounted to rotate on the shaft 24.
It will be seen that by this construction, as the shaft 7 is rocked to throw the
strippers onward and carry the sheets off the pins a, the pins are simultaneously
rocked upward towards the strippers, thus following the motion of the sheets cas
they are pressed off the cylinders by the stripper b, and permitting them to be
readily removed without danger of tearing the sheets. By actuating the pins
positively, and independently of the engagement of the pins by the strippers, a
smooth and uniform movement at very high rates of speed is attained, and there is
practically no wear between the pins and strippers, so that these parts will stand
such speed for a long time without renewal, this construction thus being well
adapted for high-speed newspaper machines.
In front of the collecting cylinder M, and above the fly O, a feeding roll is
preferably mounted, this roll being cut away opposite the pins a and strippers b,
and formed preferably, as shown, by a series of discs 26, mounted on a shaft 27,
carried in arms 28 on rock shaft 29, the discs being held under spring tension
against the collecting cylinder M by a spring pressed rod 30 connected to a crank
arm 31 on rock shaft 29. The discs 26 coact with the collecting cylinder M
between the pins a, and strippers b, and feed the sheets forward after they arę
received from the pins, and thus aid in securing their delivery to the fly O.
While this spring pressed feeding roll is preferably used, it will be understood
that it may be omitted, and the cutting cylinder N be constructed to coact with the
cylinder M in feeding the sheets, as shown in Fig. 14, the cylinder N being
preferably provided with rubber bands c, as shown, or equivalent devices, to secure
the feeding of the sheets, but this construction is not satisfactory, when many sheets
are collected at a high rate of speed, while the use of the spring-pressed feeding.a
rolls secures the proper feeding of a large number of sheets, and, by adjusting the
position of shaft 29, the exact pressure required may be secured with any number

page_text: of sheets. It is not absolutely essential that the feeding roll should be spring
pressed, if the number of sheets is not to be varied, as the roll may be set at just
the right distance from cylinder M to secure the feeding of the sheets when released
by the pins, but the construction shown is much preferable, and aids materially in
attaining a high delivery speed. With a series of independent discs 26 forming the
feeding roll, and made adjustable on their supporting shaft, it is possible also to
adjust the discs so as to bear upon the margins of the paper, thus avoiding offset,
and as the cylinder N does not touch cylinder M, all offset from the collecting
cylinder is avoided, even at high rates of speed. The machine is shown as adapted
to deliver two Beries of papers side by side, and the discs 26 as set accordingly, to
engage the centre and side margins.
The fly O consists of the usual series of fingers mounted on a rock shaft 32,
actuated to deliver the sheets by a spring-pressed bar 33, secured to crank arm 34
on shaft 32, as usual in such constructions, the shaft 32 being rocked in the opposite
direction, to return the fly N against the spring tension, by a rocking lever 35,
connected to a crank arm 36 on shaft 32 by an adjustable pitman 37, this lever 35
being provided with a bowl which runs upon a rotating cam 38 mounted in the
frame, the shaft 32 being extended through the machine, and the lever 35 and
cam 38 being mounted at the folding delivery side of the machine, for convenience
in driving.
The flat collecting delivery is all driven from the shaft L previously referred to,
as follows:
The shaft L is extended through the machine, and carries, just inside the frame,
on the collecting delivery side, a gear 108, which meshes with a gear 109 on the
shaft of the cutting cylinder N, and gear 109 meshes with gear 110 on shaft 24 of
the collecting cylinder M, so that the two cylinders are driven at the same rate of
speed. The feed roll 22 and shaft 27 carrying the spring-pressed discs 26 are
driven from gear 110 by gears 111, 112 respectively. Just inside the frame, at the
folding delivery side of the machine, the shaft L carries a small gear 113, which
meshes with a larger gear 114 carried by the shaft of cam 38, the latter being thus
driven.
In the construction shown, the parts are so timed that the shaft L, and con-
sequently the collecting cylinder M, makes two rotations to each rotation of the
impression cylinder B and the fly O makes one movement 10 each four rotations of
the collecting cylinder, the machine being designed to print two sheets at each
rotation of the impression cylinder, so that four sheets are collected and delivered
together. It is necessary, therefore, that the pins a and the strippers & be actuated
once to each four rotations of the collecting cylinder. For this purpose, the
cam 25 must be driven at a somewhat higher rate of speed than the collecting
cylinder M. In the construction shown, the cam 25 is driven from the shaft of the
cutting cylinder N by a gear 118, on said shaft, meshing with a somewhat smaller
gear 119 on the cam, these gears being so timed that the cam makes about five
rotations to four of the collecting cylinder.
The operation of the construction will be understood from a brief description in
connection with the drawings. As the web is fed to the collecting cylinder M, the
web is seized by the pins at the leading end of each sheet, as the pius pass the feed
roll 22, and each sheet is severed by one of the knives 2 of the cutting cylinder
coacting with groove 1 of the collecting cylinder, all in the usual manner. While
the number of sheets for which the parts are adjusted are being collected upon the
cylinder M, the pins a and strippers b remain stationary, with the pins projecting
forward in the line of movement of the collecting cylinder M, at an angle to the
radius of the cylinder, so as to seize the sheets properly, and the strippers are
withdrawn inside the cylinder during this movement, the bowl on crank arm 8 of
shaft 7 riding upon the concentric portion of the cain 9, and all the parts being in
the position shown in Figures 8 to 10, 12 and 13. In the present case, the number
of sheets collected to each delivery are four, but it will be understood that this

page_text: number may be varied, as desired, by changing the timing of the parts; as usual in
collecting cylinder constructions.
When the four sheets are collected, and the pins a and strippers 6 have passed
the feeding roll 26, so that the leading ends of the sheets may be thrown outward-
from the cylinder, the cam 25, in its more rapid rotation than the cylinder M, has
caught up with the latter, and the bowl on crank arm 8 now passes into the
depressed portion of the cam 25, and the strippers bare thrown outward from the
cylinder, so as to force the leading ends of the sheets off the cylinder, and at
the same time, by the connection between shafts 7 and 8, the latter shaft is rocked
to move the pins, so as to follow up the strippers as the sheets are forced outward
over the pins, the easy delivery of the sheets from the pins a being thus secured,
and all danger of tearing the sheets avoided. This position of the parts is shown
in Figs. 11 and 14, the ends of the sheets having been just thrown off from the
cylinder, so as to be carried outward sufficiently to be received by the fly 0.
-
In this position of the parts, the fly has just been returned against the pressure
of spring 33, by the action of cam 38 on the bowl of lever 35, and is now in its
innermost position, as shown in Fig. 11. The collected sheets released from the
pins are now advanced by friction between the collecting cylinder M and the
discs 26, and the sheets are fed downward in front of the stationary fly O, as
shown in Fig. 12, the leading end of another sheet having been meanwhile seized
by the pins a. As the sheets pass downward in front of the fly, the bowl of
lever 35 is just about to pass off the raised portion of cam 38, so that the spring 33
may operate to throw the fly downward to deliver the collected sheets, this position
being shown in Fig. 12. One series of collected sheets having been thus dellivered,
the fly is again returned to position by the action of cam 38 on bowl of lever 35,
and meanwhile the collecting cylinder M is collecting another series of sheets, as
shown in Fig. 13, and thus the operation is repeated.
It will be understood that short stationary guides may be used between the fly
and collecting cylinder, if desired, and such a construction is intended to be
included under the terms "delivery directly to the fly," as the equivalent of the
construction shown. Such a guide, however, will generally be found unnecessary;
It will be seen that this part of the invention provides a very simple collecting and
delivery mechanism; in which the collecting cylinder delivers directly to the fly
without the use of a switch or intermediate feeding mechanism, and it is found, in
practice, that this mechanism is operative to collect and deliver a large number of
sheets at very high rates of speed, and that the wear upon the parts upon which the
delivery of the sheets depends, is slight, and the efficiency of the mechanism not
substantially impaired thereby, so that great durability is combined with high
capacity.
It will be understood that the invention is not to be limited to the special
machine shown, as this machine has been selected only for the purpose of illustration,
and as well adapted for the embodiment of the invention, a compact machine
capacitated to produce a very large variety of products being thus provided.
Many modifications also may be made in the construction shown.
While the first part of the invention is especially adapted for application in
connection with web perfecting mechanisms employing a single type cylinder and
perfecting a web of width less than the length of the type cylinder, the invention
is not to be limited to such a construction, as it is applicable also in counection with
other printing mechanisms capacitated to print and perfect at opposite sides of the
machine, and arranged to perfect at either side. Although especially designed for
use in web printing machines, this part of the invention may be applied also to
other classes of printing machines, in which the paper is fed to the printing
mechanism in the form of sheets.
By the expression "a printing mechanism capacitated to print and perfect at
opposite sides of the machine and arranged to perfect at either side," it is meant
and intended to cover a printing mechanism so constructed and arranged that a web

page_text: or sheet may be perfected at a single run through the machine, by printing the first
impression at one or the other side of the machine, and printing the second or
perfecting impression at the opposite side of the machine, so that the web or sheet
may leave the printing mechanism in convenient position for delivery by either of
two delivery mechanisms placed at opposite sides of the machine, in accordance
with the side of the machine at which the second or perfecting impression is made.
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 :-
1. The combination with a printing mechanism capacitated to print and perfect
at opposite sides of the machine, and arranged to perfect at either side, of two
delivery mechanisms arranged at opposite sides of the machine, substantially as
described.
2. The combination with a printing mechanism capacitated to print and perfect
at opposite sides of the machine, and arranged to perfect at either side, of two
delivery mechanisms producing products of different forms, arranged at opposite
sides of the machine, substantially as described.
3. The combination with a printing mechanism, capacitated to print and perfect
at opposite sides of the machine, and arranged to perfect at either side, of feeding
and flat delivery mechanisms arranged at opposite sides of the machine, substan-
tially as described.
4. The combination with a printing mechanism capacitated to print and perfect
at opposite sides of the machine, and arranged to perfect at either side, of a folding
delivery mechanism at one side of the machine and a flat collecting delivery
mechanism at the opposite side of the machine, substantially as described.
5. The combination with a web perfecting mechanism having a single pair of
