Improvements in Web Cutting and Delivering Mechanism for
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:-
This invention relates to a delivery mechanism for web printing machines, the
object being to sever a web transversely into sheets, and to deliver the same with-
out defacing their ends by puncturing the same, and to collect a number of such
sheets or deliver the same singly, the sheets in either case being folded trans-
versely, if desired, said operations being performed continuously, or without separat-
ing one sheet from another, to provide a working space between sheet and sheet,
at or near the point of severance from the web.
Heretofore both grippers and pins have been made use of in connection with a
cutting mechanism for the purpose of holding and carrying onward the free or
leading end of the web, as such is repeatedly produced in dividing the web into
sections or sheets by severing it transversely at distances equal to a sheet's length,
the operation of the grippers or pins being to engage the leading end of the web,
and thus carry the web and each sheet so formed onward for delivery or collection,
or folding.
The presence of pin holes in sheets intended for bookwork is objectionable,
because, in producing perfect work, they must be trimmed out, and this entails
a waste of paper, and resulting loss more or less great, according to the quality
of paper used.
Various attempts have been made to avoid these pin holes, but difficulty has
been found in securing rapid successive delivery of the sheets as they are cut.
The present invention has for its object avoiding the production of pin-holes,
and at the same time securing a prompt, rapid, and satisfactory delivery. While
it is possible to dispense with the use of pins as forwarding devices, a continuous
manipulation of the sheet lengths without separation of the same, is secured.
One embodiment of these improvements includes oppositely-arranged jaws sup-
ported by a pair of rotating carriers, and an associated cutting mechanism whereby
the web may be severed into successive sheet, lengths without separating one sheet
length from another, the leading edges of which sheets are either seized for single
delivery one after another, or successive sheets are laid one upon another and
delivered into a pack of associated sheets.
A second embodiment of the invention includes an arrangement of grippers
on one rotating carrier, and an associated cutting mechanism, whereby the webs
are severed into successive sheet lengths without separating one sheet from another

page_text: The grippers swing within the periphery of the carrier in which they are
mounted, and with them co-operate fingers mounted in the other rotating carrier
on the pair, to hold the end of the sheet after it has been cut, until the grippers
grasp it, both these mechanisms causing the continuous onward movement of the
web after the sheet has been severed therefrom, without interruption of the pro-
gress of the paper, and without mutilation of the leading edge thereof.
The various improvements herein embodied will be best understood from a
description of the structure and operation of the mechanisms, and, finally, will be
specifically pointed out in the claims.
The first of the practical embodiments of the said improvements above referred
to, is found in the mechanism illustrated by Figures 1 to 12 of the drawings here-
unto attached, and the second embodiment of the invention above referred to, is
illustrated in Figures 13 to 19 of said drawings.
Figure 1 illustrates, by an end elevation, so much of the delivery apparatus
of a web printing mechanism as is necessary to an understanding of the same.
Figure 2 is a side elevation of the same, as seen looking in the direction of the
arrow 2 in Fig. 1. In this view, the web operated upon is omitted in part, for
perspicuity.
Figure 3 is a sectional end elevation of the same, taken just within the frame-
work, and as seen looking in the direction of the arrow 3 in Fig. 2, the mechanisms
being arranged to collect sheets.
Figure 4 is an enlarged partial sectional elevation of the carrier B, as seen
looking in the direction of the arrow 4 in Fig. 2.
Figure 5 is an enlarged end elevation of the carriers A, B, similar to Fig. 3,
but with the parts arranged so as to deliver successive sheets.
Figure 6 is an enlarged partial plan view of the mechanisms near the gear end.
Figures 7, 8, 9, 10, and 11, are enlarged sectional details of portions of the
carriers supporting the cutting, tucking, and nipping mechanisms, shewing the
same in various positions of their operation.
Figure 12 is an enlarged end elevation of the carriers A, B, the carrier A being
modified to include mechanism for accumulating three sheets upon the carrier B.
Figure 13 represents so much of a side elevation of a printing machine as is
necessary to illustrate the practical use of the second embodiment above referred
to of the invention.
Figure 14 is an enlarged sectional elevation of a group of associated carriers
A, B, C, in which these improvements are embodied.
Figure 15 is an enlarged plan view of said carriers, the central portions of
which are removed, to accommodate the proportions of the view.
Figures 16, 17, 18, and 19, are still more enlarged sectional views of portions
of the carriers A¹, B¹, shewing the mechanisms thereof in different positions of
their operative movements.
Referring now to Figures 1 to 12, these improvements are shewn herein as
embodied in a web perfecting printing machine. The web passes from the press
to two rotating carriers A, B, which are geared together outside the frame by
wheels 2 and 45, so as to run in unison, and support the mechanisms for control-
ling the leading ends of the sheet portions, which are the lengths that are to be
successively severed from the web, and which hereafter will be alluded to as sheets.
The material to be operated upon, as a web of paper, P, is received from a printing
machine or other source of supply, being shewn as led over a roller 30, passed
through rollers 50, 51, and thence between the carriers A, B. This material or
paper, as will be readily understood, may be a single web, or consist of a number
of webs brought together or associated by any of the means common in this art,
the web or webs being longitudinally folded, if desired, as will be well understood.
The carriers A, B, support the means for controlling the leading end or ends
of the sheet or sheets, so that the same may be delivered without injury thereto,
either singly or collectively, and before explaining the construction and operation

page_text: of the said means, the gearing illustrated in the mechanism embodying these
improvements will be explained.
Within the frame, the carrier A is provided with a wheel 40, which drives the
feed rollers 50, 51, through an intermediate 41, a pinion on the roller 50, and a
companion pinion 43 on the roller 51. This wheel 40 also drives the folding
rollers 52, 53, through companion pinions, one only, 74, of which, is shown.
At the gear side of the machine, the carriers A, B, are respectively provided with
a cam C and a cam guard X, which are fixed to the side frames by suitable arms
shown in section in Figure 5. The cam C has a high part 75 extending through-
out slightly more than half of its peripheral extent, and a low part, 76, the rest
of the distance; and the cam guard X, which is concentric with the shaft of the
carrier B throughout its greatest extent, has, at an upper point, a cam projec-
tion 70 (see Figure 12). The offices of this cam and cam guard will hereafter
appear.
The carrier A is also provided, within the cam C, with an eccentric S, mounted
upon its shaft 44 by a sleeve, which may be secured to said shaft by a set screw,
so as to move therewith, or be disengaged, so as to remain stationary. This excen-
tric S, when in action, vibrates a lever having branching cam arms 26, 27, which
respectively move in recesses in the cam C, and cam guard X, motion being
imparted to them through an arm 25 having a stud or bowl embraced by said
excentric. When the cam arm 27 of this lever is protruded within the cam
guard X, as in Figure 5, it is opposed to, and operates, the tucking and nipping
mechanisms of the carrier B, and when the cam arm 26 is protruded within the
cam C of the carrier A, as in Figure 3, it is opposed to, and operates the nipping
mechanisms of the carrier A, or protrudes the tucking blade 8 to its greatest
extent, as will hereinafter appear, and as these rocking cam levers require to be
in the position shown in Figure 5, when sheets are not being collected, but, on the
contrary, are being delivered in succession, so that the cam arm 27 projecting
within the cam guard X will render that device a constant cam, causing the tuck-
ing and nipping devices of carrier B to operate at each revolution of said carrier;
and; the cam arm 26 will be held out of operative position, so that the high
part 75 and the low part 76 of the cam C will constantly operate, to cause each
set of nipping and tucking devices of that cylinder to move in co-operation with
those of the carrier B, for carrying each sheet length onward, and at the proper
point opposite, to release said sheet to the folding rollers 52, 53. To set the lever
arms 26, 27 in this position, it is necessary to put the excentric S out of operation,
and this is done by loosening its holding set screw, and keeping it fixed when in
the position shown in Figure 5 by means of its socket, in which a sliding pin, 31
is engaged and held by the thumb screw 33 (see Figure 6).
Interiorly, the cam guard C is provided with a high part 75 and a low part 76,
for operating the nipping jaws 9, for co-operation with the tucking devices of the
carrier B, while passing the same, and at an opposite point thereto, for releasing
the sheets, as will yet appear.
The carrier A is twice the size of the carrier B, and hence is provided with
a double set of mechanisms for controlling the sheet. While the carriers might
be of the same size, and the parts be arranged to co-operate, it is preferable that
the carrier A should be twice the size of the carrier B in some embodiments of the
improvements, as in the present case, for the reason that here the carrier A, in
addition to its other functions, is made to support folding blades 34, 35, that co-
operate with the folding rollers 52, 53, in doubling or folding the sheets, as a
convenient method of finally delivering them.
These folding blades are well known as double rotating folding blades, and,
therefore, need no special description here, except to say, that the stationary
cam 90, herein shewn aids in accomplishing the semi-rotation of the blades by
acting upon their rock arms.
The carriers A, B, are provided with means for severing webs or long lengths

page_text: of material into sheets, which are of a length equal to the circumferential extent
of the carrier B, and of half the circumferential extent of the carrier A.
By reference to Figures 4 and 7 to 11, the cutting mechanism will be more
readily understood. The cutting devices consist of a cutting blade 2, extending
radially from, and supported by, the carrier B, and of cutting slots or spaces 4,
provided in the carrier A at opposite points thereof, said cutting mechanism
operating to completely sever the material transversely. The cutting blade 2
is fixedly attached in the carrier B, it may be, to a holding block 10, which is
supported in a groove in the carrier B, and secured in position by suitable bolts.
The block 10 is, furthermore, provided, in advance of the blade 2, with a spring-
seated lip 15, as in Fig. 4, the limit of whose forward movement is determined
by the stop 36, which protrudes through a recess in said spring-seated lip 15.
The carrier A is provided with a companion block 100, which provides the cutting
recess 4, and also an opposing lip 16, between which lips 15, 16, the material is
mementarily nipped, as it passes between the said carriers, by the pinching action
of the nipping lip 15. These nipping lips thus seize and hold the paper firmly,
as the knife is forced through it in the cutting operation.
Adjacent to its cutting blade 2, the carrier or cylinder B is provided with nip-
ping jaws constituted by a fixed member 3 and a movable member 5, and the
carrier A is likewise provided with nipping jaws, consisting of a fixed member 6
and a movable member 9. The movable members 5 and 9 are preferably long
plates of spring metal subdivided, if desired, and attached by their heels to the
body of the carriers A, B, respectively. Between each spring jaw and its com-
panion fixed jaw, are arranged sliding tucking blades 7, 8, which blades, at the
proper times, are reciprocated to act upon the material, as will be hereinafter
explained. This reciprocating motion is imparted to them by the following.
means.
The tucking blade 7 in the carrier B is a typical construction of all of the
tucking blades, and consists, as is shewn in Figure 4, of a narrow extremity, or
tucking blade proper, projecting from a shank heavy enough to form its recip-
rocating support, which shank is enlarged near its rear, to form a stop 13, and
has its body shaped to be guided between the bearer 18 on the fixed jaw 3, and
a bearer 17 opposite thereto. The shank of this tucking blade is attached to a
suitable number of points, by pivots 19, to rock arms 20, that project from a
shaft 38 suitably journaled in the carrier B, and provided at one end with a rock
arm 11, the bowl or stud of which travels against the inner surface of the cam
guard X and its slight enlargement 70, except when a lever arm 27 is opposed to
it, being constantly pressed in that direction by means of a spring-pressed rod 47
attached to the arm 11.
as in
As here shewn, the tucking blade 7 has its shank provided with a lug 1 adapted
for engagement with an offset or shoulder upon the movable or spring jaw 5 of
the associated nipping jaws. From this construction, it will be apparent, with the
parts arranged for co-operation as in Figure 12, that as the carrier B revolves,
the tucking blade will be withdrawn to its greatest extent, and
be held in its inward position rearward of the nipping jaws,
Figure 9, while the rock arm 11 travels in contact with the inner surface
of the cam guard X. This cam guard X, for the most part, is concentric with
the shalf of the carrier B, but has a high part 70 of short length (see Figure 12),
contact of the arm 11 with which, projects the tucking blade to its intermediate
position, as in Figure 8, while, when the cam lever arm 27 is protruded into said
cam guard, as in Figure 5, contact of the arm 11 therewith will, through the
rocking of the shaft 38 and the rock arms 20, project the said tucking blade to its
greatest extent of protrusion, or into its outward position, as in Figure 10.
Each tucking blade 8, of which there are two at opposite points in the carrier A,
has its shank provided with a lug o adapted for engagement with an offset or
shoulder upon the movable or spring jaws 9 of the associated spring jaws, and said
blades are similarly constructed and operated with respect to their nipping

page_text: jaws 6, 9, as is indicated by the rock arms 21, by which they are connected to
their shafts 39 and the rock arms 12. These arms 12 are held in operative contact
with the cam C by means of spring holding rods 37, which force the rock arms 12
outwardly, or against the cam faces. These tucking blades 8 are principally
reciprocated by the high and low parts 75, 76, of the cam C, being moved outward
to their intermediate position, that is, just behind the nipping jaws 6, 9, as in
Fig. 10, while the high part 75 of the cam is traversed by the rock arms 12, and
being withdrawn to their inward position, as in Figure 11, while the low part 76
of the cam C is so traversed. To cause the greater outward movement of these
tucking blades 8, as in Figure 9, there is provided a cam lever, one arm, 26, of
which is vibrated, so that, at times, it will protrude within the cam C, and present
its cam face for action against the arms 12, as is seen in Figure 3, or to carry said
cam face of the lever out of action, as is seen in Figure 5.
The operative positions of the cam lever arms 26, 27, which lever is at times
vibrated by the excentric S, and the consequent movements of the tucking blades 8,
as well as the movements of the tucking blade 7, depend upon the eccentric S,
which may remain stationary, or be secured to, and move with shaft 44, as will
appear in the following description of the operation.
In order to collect or associate two succeeding sheets severed from the web, the
mechanisms will be as is illustrated in all the figures except 5 and 6, that is,
the excentric S will be in action, to oscillate the lever cam arms 26, 27.
As the carriers A, B, revolve, the cutting, tucking, and nipping inechanisms
are brought into co-operation as they approach and pass their co-acting point,
which is where the carriers A, B, run nearest in contact. During about one half of
a revolution of the carrier A, or while the rock arms 12 are traversing the low
part 76 of the cam C. the tucking blades 8 are held in their inward position rear-
ward of the nipping jaws 6, 9, as is shewn in Figure 11, while during the time
said arms 12 traverse the high part 75 of the cam C, said blades 8 are moved to,
and held in, the intermediate position shewn in Figure 10, which movement causes
the lug o to open the jaws 6, 9, their further movement to their outward position,
as shewn in Figure 9, and return to their inward position, shewn in Figure 11,
being quickly effected by their rock arms 12, while they are traversing the cam
face of the lever 26, as in Figure 3, and passing thence to the low part 76 of the
cam C, their intermediate position being again attained, as in Figure 10, when
their rock arms 12 again mount and travel in contact with the high part 75 of
cam C, as in Figure 5.
During the greater part of a revolution of the carrier B, or while the rock arm 11
is traversing the inner periphery of the cam guard X, and during nearly a com-
plete revolution, if the cam lever 27 is out of operative position, as in Figure 3,
the tucking blade 7 is held in its inward position rearward of the nipping
jaws 3, 5, as shewn in Figures 3 and 9, its protrusion to its intermediate position,
as in Figure 7, which movement of it causes its lug 1 to open the jaws 3, 5, being
quickly effected by its rock arm 11 traversing the short high part 70 of cam
guard X. Its further movement or greater protrusion to its outward position, as
in Figure 10, and return to its inward position, as in Figure 9, is effected by the
rock arm 11, in traversing the cam face of the lever 27, adjusted as in Figure 5.
The web of material P, being fed onward between the carriers A, B, will be
pressed by the spring-seated block 15, as it is brought into its active relation with
the cushion block 16 (which may be rubber), as in Figure 7, and thus be tem-
porarily nipped, and supported as the cutting blade 2 is forced through it and
into the cutting slot 4, to sever the web transversely, and detach a sheet's length
therefrom.
As the cutting blade 2 is closely approaching its operative point, the cam lever
arm 26, having been swung into its operative position, shown in Figure 3, by the
excentric S, which has rocked its operative arm 25 into its innermost position, as
in Figure 3, the rock arm 12 will pass over the high cam surface presented by the
lever arm 26, and cause the tucking blade 8, then standing, as in Figure 10, in

page_text: its position of intermediate protrusion, to quickly move outward, to its position of
greatest protrusion (see Figures 7, 8, and 9), the rock arm 11 simultaneously con-
tacting with the cam enlargement 70, to move the blade 7 to its intermediate
position, and thus cause the lug 1 to open the jaws 5, during which movement the
tucking blade 8 will have carried the leading end of the web (produced by its
severance) with it, and tucked the same between the spring nipping jaws 3, 5,
said blade 7 retreating as blade 8 advances, the blade 7 releasing said jaws, so
that they nip the said web end between them as they close, and the blade 8 being
subsequently stripped from the web and jaws, as it retreats to its inward position.
The result of these movements is, that the web is simultaneously severed trans-
versely, and its detached end is controlled by the nipping jaws 3, 5 of the carrier B,
so that it thereafter moves around with that carrier, and, after a revolution of the
carrier B, the leading end of the sheet is again brought between the carriers A, B,
for association with a succeeding sheet's length of the web. The carries A will,
meanwhile, have made a half revolution, to bring its companion set of cutting,
tucking, and nipping devices into cooperation with the like devices of carrier B.
During these rotative movements of the carriers A, B, the cam lever 25 will
have been moved by the excentric S, so as to present the cam face of its arm 27
in position for action upon the rock arm 11, and so that the cam face of its arm 26,
will stand in its inoperative position, or so that it will not be engaged by the rock
arm 12, as in Figure 5.
As the cutting blade 2 is again closely approaching its operative point, the rock
arm 11 of the carrier B will engage the cam surface of the lever arm 27, and
cause the tucking blade 7 to quickly move outward to its position of greatest pro-
trusion, as in Figure 10, during which movement of this tucking blade 7, it will
have carried the severed end of the web, and the leading end of the preceding sheet,
with it, thus tucking said ends, now lapped together, between the spring nipping
jaws 6, 9, and, as quickly retreating, leave said ends nipped between said jaws,
as in Figure 11, the tucking blade 8 having just in advance, or about simul-
taneously with the protrusion of blade 7, been moved to its intermediate position
of protrusion, as its rock arm passed from the low part 76 to the high part 75
of the cam C, during which movement, its lug o opened the jaws 6, 9, to receive
the paper carried between them by the blade 7. After passing over the high
parts of the cams; the blades 7, 8, simultaneously retreat, thus causing the nipping
jaw 9 to bear the paper into the embrace of itself and co-acting jaw 6, while the
blade 7 strips itself therefrom, thus leaving the ends of two sheets nipped by
the jaw 6, 9, as in Figure 11, which carry them onward for delivery.
The results of these movements are, that the web is simultaneously again severed
transversely, its detached forward end has associated with it the leading end of
the preceding sheet, the two ends are controlled by the nipping jaws 6, 9, of the
carrier A, and the sheets thus lapped together, or associated, thereafter move
onward around said carrier A, from which they may be delivered in any approved
way. Sheet after sheet will thus be laid one upon another on the carrier B, so
long as the lever arms 26, 27, remain in the positions shown in Figure 3. Thus,
three or any number may be collected upon the carrier B, and discharged on masse
therefrom, whenever the lever arms 26, 27, are brought into the position shown
in Figure 5, when, as we have seen, the leading ends of the said sheets will be
delivered into the embrace of the jaws of the carrier A, for simultaneous delivery.
This collecting or associating of successive sheets for simultaneous delivery may,
by slight modification of the devices, be extended to include any desired number
of sheets.
Thus, if the excentric S has substituted for it a suitably shaped cam, as 60.
and the same is so shaped and moved as to throw the cam arms 26, 27, from their
position shown in Figure 12, to that position shown in Figure 5, at, say, every
third, fourth, and so on, revolution of the carrier B, the sheets held in the embrace
of the jaws 3, 5, will be retained there, and successive sheets added thereto by the
operation of the tucking blade 8, which sheets will thus be carried around upon

page_text: the carrier B until their number, whatever it may be, is discharged from said
jaws, when the cam arms 26, 27, are in the position of Figure 5, and be delivered
to the jaws 4, 6, of the carrier A, as just before explained.
In Figure 12 is shewn a means illustrative of the said modification, the
mechanisms being provided to cause the accumulation of three sheets upon the
carrier B. This consists of a box cam 60, suitably mounted to turn upon the
shaft 44 of carrier A, in the place of the excentric S, said cam having a toothed
periphery constituting a wheel 62, by which said cam is revolved. To suitably
revolve this cam 60, a wheel 69 is mounted fast upon said shaft 44 alongside the
wheel 62, and these wheels 62 and 69 are geared together by an intermediate train
composed of wheels 63, 65, 66, which are carried by the side frame and brackets
therefrom, 63 meshing with the wheel 62, and 66 meshing with the wheel 69.
By this arrangement, the first and second sheets of a pack of three are carried
around upon the carrier B, and accumulated, while the third sheet is associated
therewith, and passed off for delivery as a component part of said pack of three.
Other similar modifications may be made to increase the number of sheets com-
posing each accumulated pack.
If it is desired to deliver single sheets, the excentric S is locked stationary, as
before described, by means of the locking arms 31, whereupon the lever arms 26, 27,
will be maintained in the positions shown in Figure 5, so that only the cam
will affect the movement of the tucking blade 8, this cam then causing the said
blades, at each rotation of the carrier A, to be protruded, as the rock arms 12
travel over its high part 75, and be withdrawn as said arms 12 travel over its
lower part 76; and the tucking blade 7 will be protruded, and withdrawn by the
cam face of the lever arm 27, at each revolution of the carrier B. Now, as the
cutting, tucking, and nipping devices come into operation, the blade 7 will move
outward, to engage and deliver the leading end of successive sheets into the nip
of the jaws 6, 9, which will nip and carry said sheets successively onward upon
the periphery of the carrier A, for delivery in any manner.
But as it is desirable to deliver sheets, whether carried onward singly, or consist-
ing of two associated together, with at least one transverse fold, the said sheets,
whether carried onward singly, or collectively thereby, will have their leading
ends released from the nipping jaws 6, 9, at the proper time, and the said sheets
will preferably be folded, or doubled, by means of the one or the other of the
double folding blades 34, 35, into the nip of the folding rollers 52, 53, their lead-
ing ends being drawn thereby out of the jaws 6, 9, and as these sheets emerge
from said rollers in a once-folded condition, they may be conveyed to a piling
device or be intermediately again folded, as may be desired, by any of the means
common in this art.
The nipping jaws herein shewn and explained have been described as being
opened by means of lugs upon the shanks of the tucking blades. It is possible,
especially where strong paper is operated upon, to open the spring-like nipping
jaws for the reception of the paper, by means of the tucking blades themselves
forcibly entering between them, but, in this case, the tucking blades should have
such shape, and the movable nipping jaws be so constructed, that the tucking
blades will readily enter between, and cause the opening of said jaws, while the
resiliency of the spring jaws themselves will close, and tend to hold the jaws closed.
It is preferred, however, that the spring jaw shall be opened by a positive move-
ment, and this is attained in the present instance, by means of lugs on the tuck-
ing blades, which coact in their forward movement by contact with suitable
shoulders on the spring jaws, contact of the two causing the spring jaw to be be
opened, and its resiliency to close upon the retirement of the nipping blades. It
will thus be seen that when the rock arms 12 are traversing the high part 75 of
the cam C, what has been called their intermediate protrusion is sufficient to
cause contact of the lugs on the tucking blades with the shoulders on the spring
jaw, and open the nipping jaws. Thus, the jaws of the carrier A will be opened
at the point where they are to receive the end of the material, independently of

page_text: the tucking blade to enter between them, and also at the opposite point, where they
are to release the same, when it is to be folded between the folding rollers 52, 53.
Instead of shaping the cams so as to withdraw the said tucking blades, or cause
their retiring action, said blades might be spring-seated, and the forward move-
ment of one cause the retiring movement of the other.
While it is desirable, especially in the collecting or associating operation, to
provide the sheets by cutting the web transversely by an associated cutting
mechanism, the sheets may be previously cut and fed in succession to these devices.
So far as sheet forming by severing, the web, and a mere delivery of each sheet, is
concerned, the tucking blade 7 might be fixed in a protruded position, but in
consequence of the further operation of directing sheets to cylinder B to be carried
thereby, it is required that this blade reciprocate, in order not to obstruct that
operation.
Referring now to Figures 13 to 19, the second embodiment of the invention
will be described. These improvements also are shown as embodied in a web
perfecting printing machine.
In Figure 13 is shown the last impression cylinder I, and the last type cylinder T,
of a web perfecting printing machine, and the printed web W therefrom is shown
as passing over guiding rollers 150, 160, 170, to and between the rotating carriers A¹
and B of a delivery mechanism, said delivery mechanism additionally having, in
this instance, a delivering cylinder C¹.
As the invention is comprised within this delivery apparatus, no further descrip-
tion of the printing machine is necessary, further than to say that, in this case,
as in the case of the embodiment of this invention before described, any printing
.machine may be used in connection with either form of the invention, the pro-
duct of which is led to the delivery apparatus in which the invention is embodied,
such delivery apparatus having connected with it a delivery cylinder C¹, or other
means for disposing of the sheets produced by the mechanism embodying the
improvements.
Referring particularly to Figures 14 and 16 to 19, the rotating carrier A¹ is
preferably of such a size that it aids in the production of three sheets at each
revolution, and it is, according to its size, provided with one, two, or more sets of
gripper 106, each of which is mounted on a rock shaft 110, provided with a cross
head 111, one end of which is connected to a spring rod 124, acting to hold the
grippers closed, and the other end of which carries a stud or bowl contacting with
cains X and Y¹, by which said shaft is vibrated, as is common, to open and close
said grippers. These grippers 106, however, are so shaped that they do not pro-
trude beyond the periphery of the carrier A¹, but, on the contrary, make a sweep
which is nearly. coincident with the curved periphery of the carrier A¹, the centre
of their carrying shaft 110 being directly under, or in a radial line with the points
of the grippers, when closed (see Figure 14), so that, in opening, the are described
by the points of the grippers will be within the periphery of the cylinder, thus
allowing the grippers 106 to be opened underneath the incoming web, without
puncturing or contacting with it. When closed, these grippers 106 press upon
an angular faced bearer 109, inclined inwardly from the periphery of the carrier A¹,
but so shaped between the gripper's points, as to provide a space or cutting slot 102,
that will be bridged by the passing web. For cooperation with these grippers 106,
the companion carrier B, having a circumferential extent equal to that of two
sheets, carries two sets of presser fingers 107, each set of which is hung upon a
rock shaft 112, that is provided with a rock arm 120, one end of which is attached
to a spring rod 125, whereby the fingers are spring seated, so that they are
normally held inwardly or within the periphery of the carrier B₁, as in Figure 16,
and which shaft 112 has the other end of its rock arm 120 provided with a stud
or bowl, whereby it is rocked, to project the fingers into action by its contact
with a stationary cam 121.
As these presser fingers 107 at times sweep within the peripheral line of the
carrier A¹, for co-operation with the grippers 106, and both are momentarily

page_text: closed against the angular bearer 109 (see Figure 14), the grippers 106 have their
outer ends recessed, as shown in Figure 15, to provide for this conjoint action in
holding the end of the paper. The carrier A¹ is, of course, provided with recesses
in which the grippers 106 and the fingers 107 may sweep.
The carrier B¹ is
provided with a stationary projecting knife 113, furnished, as is usual, with a
spring-seated or elastic presser block 114 (see Figure 16), which knife moves
against said web, and severs it by perforating that part of the web which bridges
the space or cutting slot 102 in the carrier A¹, and as the fingers sweep close to
the blade 113, the presser block 114 has recesses 105 to permit of this movement.
As the mechanisms embodying these improved sheet-carrying devices are pro-
vided with means for folding the sheets thus formed, the same will be described,
in order that the delivery of the sheets, as an entirety, may be best explained in
the description of the operation..
The carrier A is provided at points, midway between the grippers 106, with
rotative folding or tucking blades 115, that are mounted
cach provided with a rock arm connected to a spring rod rock shafts 108,
127, whereby said
blades 115 are normally held within the carrier A', said shaft also having a rock
arm 116 that contacts with a cam D¹, to cause said blade to vibrate or swing out-
ward, in performing the tucking or folding operation, as in Figure 19. The
carrier B is also provided with two sets of nipping jaws. In each set, there is
a stationary jaw 103 and a moveable jaw 117, the latter being carried by a rock
shaft that is provided with a cross-head 123, one end of which is attached to a
spring rod 128, whereby the said movable jaw is normally held closed, and its other
end provided with a stud or bowl, whereby, through contact with a stationary
cam E, it is held open at the proper periods of time (see Figure 19). The
carrier C is provided with two sets of ordinary grippers 119 projecting from
shafts 130 that carry. cross heads 118, one end of which is attached to a spring
rod 129, whereby they are normally held closed, and the other end of which head
carries a stud or bowl that contacts with a fixed cam F¹, whereby said grippers
are properly opened to receive the folded sheet from the nipping jaws 117 and
deliver the same. In this instance, the carrier C¹ has tapes 122 running around
it and in contact with the carrier B¹, which tapes aid in the performance of the
folding operation.
As the carriers rotate in unison, and the grippers 106, carried by the carrier A'
and the cutting blade 113, carried by the carrier B, are approaching the point of
nearest contact between these carriers, (see Figure 16), the web W will be laid
upon the periphery of the carrier A' overlying the cutting slot 102 in the carrier A¹,
the grippers 106 then standing open, but on the rear side of the web W, then
stretched over them.
When the carriers A', B¹, have advanced these mechanisms to the position
shown in Figure 17, the spring-seated presser block 114 will bear upon the paper
web each side of the cutting slot 102 in the carrier A', and hold the web while
the cutting blade 113 is forced through the same, to sever a sheet's length there-
from, as the carriers A¹, B¹, move onward. Simultaneously with, this cutting
action, the fingers 107 are swung outwardly by the action of the cam 121 on
the rock arm 120, thus pressing the front edge of the web W, then overlapping
the angular bearer 109, as in Figure 18, this action being slightly in advance of
the closing movement of the grippers 106, caused by their rock arm 111 descend-
ing onto the low part of the cam X', which gripper movement is made, as before
stated, in an arc that swings their points behind the web, seizing said web by
bearing it against the angular face of the bearer 109, the bifurcated ends of said
grippers 106 moving past the projecting points of the fingers 107 and pressing
the web end onto the bearer.
This disposition of the grippers 106 is maintained long enough to carry the
leading end of the web a half sheet's length distant from the point where tne web
was severed, as in Figure 19, whereupon said grippers are opened by the action
of cam Y' to release the end of the web (see dotted lines Figure 19), simultaneously

page_text: or thereabouts with the rocking movement of the tucking blade 115, caused by the
high part of the cam D¹, which acts to tuck the middle transverse portion of the
sheet into the recess in the carrier B', in which the jaws 117 vibrate, which jaws
make this movement by the action of the cam E¹ in such manner as to receive
the doubled or folded part formed by the tucking blade 115, allow said blade to
be removed therefrom and the sheet length to be clamped by said jaws 117, so
that thereafter it will move with the carrier B¹, as is shown by the dotted lines
in Figure 19, and its tail end will be lapped upon the companion half of the sheet
it partly forms.
The continued rotative movement of these carriers causes the folded sheet to
be laid upon the carrier 11 (see Figure 14), and it is finally delivered therefrom
in a manner too well understood to need any detailed description. When the
cutting blade and the fingers of the carrier B₁ come into cooperative position with
respect to the next set of grippers 106, the cutting operation is again performed,
the leading end of the web is seized by the grippers 106, and the described folding
and delivering operations are repeated.
By this improved construction and operation of the mechanisms, the web is
severed to divide it into lengths without losing the continuity between sheet and
sheet; the leading end of the web formed by the cutting operation, and which
otherwise would be free, is not only clamped to the cylinder A¹ by the fingers 107,
but this clamping of it is maintained for a period that will enable the rotative
movement of the carrier B₁, supporting these fingers, to withdraw the cutting
knife out of the carrier A¹, thus enabling the grippers 106 to unobstructedly make
their sweeping movement in closing down upon the end of the sheet, while it is
held, by the fingers 107, onto the carrier A¹, and seize the same, by clamping it
to the inclined face of the bearer 109. This accomplished, the fingers 107 are,
by the further rotative movement of the carrier B¹, withdrawn from the end of
the web, and it is then wholly controlled by the grippers 106. These grippers are
thus enabled to move in both directions without contact with the overlying paper
or the cutting blade 113; the web is positively and continuously held and moved
onward; and the sheets are produced without any abrasion of their leading ends,
either upon the surface, or through the body thereof.
This invention is especially advantageous in that class of web machines used
for the production of books, magazines, and pamphlets, and in which it is usual
to associate two or more sheets together, and fold them simultaneously. This
association or collection of sheets is accomplished upon carrier A¹, which, for
convenience of illustration, is shewn in Figures 13 to 19, as arranged for collect-
ing two sheets. The cam D¹, which is pivoted at its lower end, and operates the
tucking blades 115, is arranged so that it may be swung out of the path of the
rock arms 116 alternately by means of a connecting rod 140, to which suitable
reciprocations are imparted by means of a cam G¹ fast upon the shaft of carrier B¹;
and the cam Y', which opens the grippers 106, is also arranged so that it may be
swung out of the path of rock arms 111 alternately by a wrist pin 104 on the
end of the shaft of carrier B¹, and a connecting rod attached to a rock arm on the
end of the shaft to which said cam Y¹ is attached (see Figure 13).
By this arrangement, the forward end of an incoming sheet will he clamped
to the carrier A¹ by the grippers 106, and carried around, but will neither
be released by these grippers upon its first revolution, nor will the tucking
blade 115 be projected to fold it into the nip of the jaws 117, for their respective
cams and D will have been, during that revolution, swung out of action.
But upon the next revolution of carrier A¹, during which these cams resume their
operative positions, a second sheet will be superimposed upon the first, the
grippers 106 will open to receive its end, and though clamping it to the first
to carrier A¹, will release both at the proper time for the tucking blade 115 to
tuck both sheets into the nip of the jaw 117, whereupon the two sheets will be
folded off onto carrier B, and be delivered by cylinder C¹.
Although an arrangement of the carriers suitable to the collection of two sheets

page_text: is shown, and is sufficient as illustrative of this operation, it is practicable to
make the carrier A¹ of such a size as to collect three or more sheet lengths, is
may be desired.
The arms 136 projecting from the shaft 112 which also carries the presser
fingers are not essential, though they afford a convenient means for bridging the
opening in the shell of the carrier B, which is a convenient construction to pro-
vide for the carriage of the tapes, and yet aid access to the fingers for adjusting
As shown, they slightly rock with the shaft, but might be stationary,
