Improvements in Printing and Sheet Delivering Mechanism.
I, WALTER SCOTT, residing at No. 418 East Front Street, Plainfield, in the
County of Union and State of New Jersey, United States of America,
Manufacturer, do hereby declare the nature of the said invention to be as
follows:-
This invention relates to that class of printing-presses in which the paper is
supplied from one, two or more rolls or webs, and is printed, folded, cut and
delivered as a single product or as two or more products.
Two, three or more similar rotary printing presses are provided and these are
usually placed one above the other, and the rolls of paper are supplied at one end
of the machine. I provide a lifting device for the rolls so as to raise them to any
desired press, and there are drop arms that are raised by the shaft of the paper roll
and drop beneath such shaft so as to form ways upon which the roll can be moved
along into position.
In some kinds of printing machines, swinging brackets may be made use of to be
swung in below the shafts and form ways upon which the paper roll is moved along
into position, and an overhead railway and hoist-way may be used in handling the
roll of paper.
In printing machines where two or more webs are employed from a roll of paper,
difficulty has been experienced in applying the proper tension to the webs so that
they will all pass through the printing operations and come together with proper
register where they are associated and folded together and cut off. To regulate
this tension a friction is applied to the shaft of each roll and this friction is adjustable
and also automatic.
A roll is provided for each web that can rise or fall according to the tension,
and an indicator is employed in connection with this roll so that the attendant at
the feeding-in end of the machine can see the tension to which each web is subjected
and be can regulate the friction accordingly by hand, and in connection with this
roll that can rise or fall, an automatic mechanism is also employed to vary the
friction upon the shaft of the paper roll according to the tension on the web.
As these printing machines are often of considerable length, the attendant at
the delivery end is advantageously supplied with connecting devices extending to
the friction mechanism upon the feeding-in rolls, so that he can vary such friction
to aid in rendering the register accurate of the webs as they are brought together,
and with this object in view shafts are extended from the friction mechanism
upon the paper rolls to the associating, folding and cutting portion of the
machine.
The friction devices upon the shafts of the paper rolls are peculiarly constructed
so as not to be affected by atmospheric conditions or by the warmth that may be
developed by the frictional contact of the surfaces.
In bringing the webs together one upon the other, adjusting devices are provided
in the form of laterally moving rollers to ensure proper register of the printed
webs, and in some instances, one or more of the webs is slit longitudinally by a
cutter so as to be associated with one or more of the full width webs, or one web
is carried over turners to associate it with another web or the other half web by
bringing one web under or over the other.
It is advantageous to make the roller that receives the webs as they are

page_text: superposed one on the other, with a series of annular depressions with convex
surfaces over which the belts in the ranges of belts pass, as this lessens the risk of
the webs becoming slack in the middle portions and tighter at the outer edges;
and in printing, it is advantageous to bring the webs together in such a manner
that the surfaces last printed will be outward, so as to be exposed to the atmosphere
and lessen the risk of the impression becoming blurred.
The webs are carried over converging inclines to fold such webs longitudinally,
and the folded webs pass off the inclines between rolls or guides that are tapering
near the apex of the folding incline, and this apex is advantageously below a plane
passing through the axes of the rolls or guides, so that the longitudinal fold is
applied in the web or webs without the risk of injury to the paper, and the apex
of the folding incline is sometimes rounding in consequence of the two rounded
edges of the inclined folder coming together as a mitre, hence the surfaces
correspond, or nearly so, to the contour of the paper as is folded.
Means are provided for adjusting the proximity of the pairs of folding rolls or
guides and also of the rolls that draw the folded web along and complete the
creasing of the fold, and the pairs of rolls are fitted so as to yield equally at each
side of the folding incline according to the thickness of the product passing
through between them, and the rolls or guides can be thrown open simultaneously
to facilitate the entering of the folded web or to allow for the passage of any fold
or obstruction in the product.
In some instances two sets of folding inclines are provided so as to allow for
separating the printed webs into two distinct products, and the folding inclines are
advantageously placed back to back to facilitate the associating together of the
webs in forming the two products.
The longitudinally folded products are cut off in sheets or lengths by the action
of shears or perforators upon cylinders, and it is advantageous only to use
perforators so that the webs may continue their movements between rolls and
guiding belts, and peculiarly constructed breaker-bars upon cylinders travel with
accelerated velocity so as to grip the web and tear apart or separate the products
at the perforations and forward the same to the transverse folding devices, and the
belts and parts are so arranged that the products after thus being separated can be
folded separately or brought together and folded as one product.
I prefer and use transverse folders in the form of creasing-bars that are rotated
at the end of arms so as to press the folds of the product between rolls that carry
off such product as it is folded, and the folded products are received into boxes or
receptacles and moved along in the same. Usually endless belts are provided
upon which the folded products drop and are laid down successively by vibrating
fingers or arms.
In printing machines of the character before describod, I have discovered that
there is a tendency to detain the web that passes in contact with the converging,
folding incline in consequence of the friction upon the surface thereof, and the next
web lying upon the first web is not exposed to this tendency. In addition to this
the webs usually pass around one or more rolls, formers or curved surfaces, and
hence the outer web is in a longer arc of a circle than the inner web, in consequence
of the thickness of the respective sheets.
These conditions conspire to cause a greater length of one web to pass through
the press than of another web. This difficulty is counter-acted by making the
cylinders in one printing machine slightly smaller than the cylinders in the other
printing machine. To illustrate-if four printing presses and four webs are
employed in the printing machine and they were associated together and brought
over one roll and an adjacent longitudinal converging folder, the bottom web might
be exposed to a friction and detention that would produce a fullness or looseness
in the under web, between the printing press and the folding incline, of perhaps
half an inch or more, on fifty impressions.
To compensate and neutralize this tendency, the cylinders of the lower printing
press should be slightly less in diameter than the cylinders of the upper printing

page_text: press, and the rolls and cylinders in the intermediate presses should be of pro-
portionate sizes in order that the webs may all be supplied to the place where they
are associated together, so that looseness in either of the webs is prevented,
the proper tensions are maintained and an accurate register of the printed matter
is secured.
The object before mentioned may be accomplished by varying the sizes of the
type cylinders or the impression cylinders, or both, in the respective presses, so as
to graduate such sizes and insure the proper movements of the respective webs
according to the circumstances as they are found to exist, having reference to the
average character of the paper and the average conditions under which the
respective webs pass to the place where the webs are cut off to form the completed
product, and while it is true that the sheets as thus ent off may vary slightly in
their measurements, this is found to be immaterial as it is not noticeable in news-
paper work, and in book work the sheets being small the differences in size are not
noticeable.
When this printing machine is used for printing upon one web that is slit
longitudinally and each half-web folded lengthwise, then one folded half-web in
some instances is carried across and brought into register with the other folded
hall-web and the two are cut off together as one product, but when the half-webs,
as folded longitudinally, are to be separately delivered, they are both carried
through between cutters or perforators and delivered into suitable receptacles, but
usually the sheets that are folded longitudinally before being cut off are folded
transversely before being delivered into the receptacles.
The webs that are slit longitudinally and folded longitudinally (either as single
thicknesses or after two or more webs have been brought together) are associated
together by carrying the folded half-webs laterally and outwardly so as to pass the
upper folded half-web outside the longitudinal folder of a lower web or to pass the
same between two of such longitudinal folders, and then such folded wehs are
passed around rolls and brought together so as to associate together flatwise two,
three or more longitudinally slit and longitudinally folded products, after which
the astoriated products are cut off and folded, or otherwise treated, similar to
a single longitudinally folded web.
One feature of the present improvement relates to the devices whereby the folded
products are received and packed into receptacles. These receptacles are usually
trough-shaped and sometimes provide with belts running along the bottom to
convey the folded products along in the receptacles, and the packers are in the
form of bars or fingers that rise and fall and are moved forward and backward,
and usually these packing devices act between guide bars or fingers adjacent to
which the sheets run down from between the rollers in the transverse folding
device, and provision is made for holding up one folded product automatically
every fifty or one hundred of such products, so that the upper edge of such folded
product standing at an elevation facilitates the separation of the papers or products
with the desired number in ench pile.
In this printing-press it is sometimes necessary to use webs of different widths,
and when these are slit centrally and longitudinally and each half-web folded
longitudinally, it is necessary to adjust the positions of the longitudinal folders to suit
the different widths of half-webs so as to fold such half-webs in the middle. With
this object in view, the frames carrying the longitudinal folders are adjustable
towards and from each other, such frames carrying not only the longitudinal
folders, hut also the forwarding rollers that act with them; and to facilitate the
insertion of the web, these rollers are mounted in. movable bearings so that one
roll in each pair of rolls can be drawn aside laterally, and to effect these move-
ments, screw shafts with cones upon them to act upon the levers that carry the
roller bearings are made use of, such screw shafts being geared together so as to be
rotated simultaneously in acting upon the different rolls.
In some instances the three webs' require to be split longitudinally and one half-
web of each web folded around turning bars so as to bring the two halves of the

page_text: web one upon the other, and in this case the longitudinal folding inclines may be
placed one behind the other, either in line with one half of the split web or at
right angles thereto. This press is also adapted to collecting two or more sheets
or folded products one upon the other and delivering the same to the folding
mechanism that folds the collected products as one product previous to delivery
into the receptacle.
With this object in view, one or two collecting cylinders may be provided, there
being grippers upon the collecting cylinder to grasp the advancing ends of the
sheets as they are pressed successively to the collecting cylinder.
Sometimes the collecting cylinder has three sets of grippers, and within aud
eccentric thereto is a shaft and arms carrying two folding blades that act in the
middle of ench sheet to fold the same outwardly between rollers, the arms and
blades revolving three times to two revolutions of the gripper cylinder, and when
one blade is thrown out of action each set of grippers will take two sheets one over
the other, before being delivered and folded, thus allowing the folded sheets to be
delivered single or one folded sheet collected on another before being delivered and
folded.

Improvements in Printing and Sheet Delivering Mechanism.
I, WALTER SCOTT, residing at No. 418 East Front Street, Plainfield, in the
County of Union and State of New Jersey, United States of America, Manu-
facturer, 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 presses to which the present invention is applied are adapted to receiving
the paper from one, two or more rolls or webs, printing the same and folding and
delivering the products with great rapidity and substantially automatically.
In the manufacture of printing presses of the general class which is usually
known as "web perfecting printing presses," the printed sheets require to be
associated together in various ways: for instance, a single sheet may be folded and
delivered as a four-page paper, or two or more sheets can be brought together and
delivered as a four, eight, or twelve-page paper, or whole and half sheets can be
brought together to form six or ten or fourteen-paged products, and sometimes the
presses are run to the greatest advantage by folding the webs longitudinally before
cutting off the sheets. In other instances the presses are run to better advantage
by cutting off the sheets before folding them either longitudinally or transversely;
and in order to fully disclose the nature of the present invention, I have shown
the manner in which the essential features of the present invention are brought
together, and also illustrated the modifications in the presses by which the same
are adapted to the different conditions of use by the different devices that are
brought together to act to the best advantage according to the character of
product required from the printing machines.
The features of the present invention are, for convenience, classified under the
following general heads:
1st. Two, three or more similar rotary printing presses are provided and these
are usually placed one above the other, and the rolls of paper are supplied at one
end of the machine. I provide a lifting device for the rolls so as to raise them
.to any desired press, and there are drop arms that are raised by the shaft of the

page_text: paper roll and drop beneath such shaft so as to form ways upon which the roll
can be moved along into position.
2nd. In some kinds of printing machines, swinging brackets may be made use of
to be swung in below the shafts and form ways upon which the paper roll is moved
along into position, and an overhead railway and hoist-way may be used in handling
the roll of paper.
3rd. In printing machines where two or more webs are employed from a roll
of paper, difficulty has been experienced in applying the proper tension to the webs
so that they will all pass through the printing operations and come together with
proper register where they are associated and folded together and cut off. To
regulate this tension a friction is applied to the shaft of each roll and this friction
is adjustable and also automatic.
4th. A roll is provided for each web that can rise or fall according to the tension,
and an indicator is employed in connection with this roll so that the attendant at
the feeding-in end of the machine can see the tension to whicb each web is subjected
and he can regulate the friction accordingly by hand, and in connection with this
roll that can rise or fall, an automatic mechanism is also employed to vary the
friction upon the shaft of the paper roll according to the tension on the web.
5th. As these printing machines are often of considerable length, the attendant
at the delivery end is advantageously supplied with connecting devices extending
to the friction mechanism upon the feeding-in rolls so that he can vary such
friction to aid in rendering the register accurate of the webs as they are brought
together, and with this object in view shafts are extended from the friction
mechanism upon the paper rolls to the associating, folding and cutting portion
of the machine.
6th. The friction devices upon the shafts of the paper rolls are peculiarly con-
structed so as not to be affected by atmospheric conditions or by the warmth that
may be developed by the frictional contact of the surface.
7th. In bringing the webs together one upon the other, adjusting derices are
provided in the form of laterally moving rollers to ensure proper register of the
printed webs, and in some instances, one or more of the webs is slit longitudinally
by a cutter so as to be associated with one or more of the full width webs, or one
web is carried over turners to associate it with another web or the other half
web by bringing one web under or over the other.
8th. It is advantageous to make the roller that receives the webs as they are
superposed one on the other, with a series of annular depressions with convex
surfaces over which the belts in the ranges of belts pass, as this lessens the risk of
the middle webs becoming slack or falling behind in the register as the pulling
action is applied to the outer webs; and in printing it is advantageous to bring
the webs together in such a manner that the surfaces last printed will be outward,
so as to be exposed to the atmosphere and lessen the risk of the impression
becoming blurred.
9th. The webs are carried over converging inclines to fold such webs longi-
tudinally, and the folded webs pass off the inclines between rolls or guides that are
tapering near the apex of the folding incline, and this apex is advantageously
below a plane passing through the axes of the rolls or guides, so that the longi-
tudinal fold is applied in the web or webs without the risk of injury to the paper,
and the apex of the folding incline is sometimes rounding in cousequence of the
two rounded edges of the inclined folder coming together as a miter, hence the
surfaces correspond, or nearly so, to the contour of the paper as it is folded.
10th. Means are provided for adjusting the proximity of the pairs of folding
rolls or guides and also of the rolls that draw the folded web along and complete
the creasing of the fold, and the pairs of rolls are fitted so as to yield equally at
each side of the folding incline according to the thickness of the product passing
through between them, and the rolls or guides can be thrown open simultaneously
to facilitate the entering of the folded web or to allow for the passage of any fold
or obstruction in the product.

page_text: 11th. In some instances two sets of folding inclines are provided so as to allow
'for separating the printed webs into two distinct products, and the folded inclines
are advantageously placed back to back to facilitate the associating together of the
webs in forming the two products.
12th. The longitudinally folded products are cut off in sheets or lengths by the
action of shears or perforators upon cylinders, and it is advantageous only to use
perforators so that the webs may continue their movements between rolls and
guiding belts, and peculiarly constructed breaker bars upon cylinders travel with
accelerated velocity, so as to grip the web and tear apart or separate the products
at the perforations and forward the same to the transverse folding devices, and the
belts and parts are so arranged that the products, after thus being separated, can
be folded separately or brought together and folded as one product.
13th. I prefer and use transverse folders in the form of creasing bars that are
rotated at the end of arms so as to press the folds of the product between rolls that
-carry off such product as it is folded, and the folded products are received into
boxes or receptacles and moved along in the same. Usually endless belts are
provided upon which the folded products drop and are laid down successively by
vibrating fingers or arms.
14th. In printing machines of the character before described, I have discovered
that there is a tendency to detain the web that passes in contact with the converging,
folding incline in eonsequence of the friction upon the surface thereof, and the
next web lying upon the first web is not exposed to this tendency. In addition to
this, the webs usually pass around one or more rolls, formers or curved surfaces,
and hence the outer web is in a longer arc of a circle than the inner web, in
consequence of the thickness of the respective sheets.
These conditions conspire to cause a greater length of one web to pass through
the press than of another web. This difficulty is counteracted by making the
cylinders in one printing machine slightly smaller than the cylinders in the other
printing machine. To illustrate-if four printing presses and four webs are
employed in the printing machine and they were associated together and brought
-over one roll and an adjacent longitudinal converging folder, the bottom web
might be exposed to a friction and detention that would produce a fulness or
looseness in the under web, between the printing press and the folding incline, of
perhaps half an inch or more, on fifty impressions.
To compensate and neutralize this tendency, the cylinders of the lower printing
press should be slightly less in diameter than the cylinders of the upper printing
press, and the rolls and cylinders in the intermediate presses should be of
proportionate sizes in order that the webs may all be supplied to the place where
they are associated together, so that looseness in either of the webs is prevented,
the proper tensions are maintained and an accurate register of the printed matter
is secured.
The object before mentioned may be accomplished by varying the sizes of the
..type cylinders or the impression cylinders, or both, in the respective presses, so as
to graduate such sizes and insure the proper movements of the respective webs
according to the circumstances as they are found to exist, having reference to the
average character of the paper and the average conditions under which the
respective webs pass to the place where the webs are cut off to form the completed
product, and while it is true that the sheets as thus cut off may vary slightly in
their measurements, this is found to be immaterial as it is not noticeable in news-
paper work, and in book work, the sheets being small, the differences in size are
not noticeable.
15th. When this printing machine is used for printing upon oue or more webs
that are slit longitudinally and each half web folded lengthwise, then one folded
half-web in some instances is carried across and brought into register with the
other folded half web and the two are cut off together as one product; but when
the half webs, as folded longitudinally, are to be separately delivered, they are
both carried through between cutters or perforators and delivered into suitable

page_text: receptacles, but usually the sheets that are folded longitudinally before being cut.
off are folded transversely before being delivered into the receptacles.
16th. The webs that are slit longitudinally and folded longitudinally (either as
single thicknesses or after two or more webs have been brought together), are
associated together by carrying the folded half-webs laterally and outwardly so as-
to pass the upper folded half-web outside the longitudinal folder of a lower web or
to pass the same between two of such longitudinal folders, and then such folded
webs are passed around rolls and brought together so as to associate together
flatwise two, three or more longitudinally slit and longitudinally folded products,
after which the associated products are cut off and folded, or otherwise treated,.
similar to a single longitudinally folded web.
17th. One feature of the present improvement relates to the devices whereby
the folded products are received and packed into receptacles. These receptacles-
are usually trough-shaped and sometimes provided with belts running along the
bottom to convey the folded products along in the receptacles, and the packers are
in the form of bars or fingers that rise and fall and are moved forward and back-
ward, and usually these packing devices act between guide bars or fingers adjacent
to which the sheets run down from between the rollers in the transverse folding.
device, and provision is made for holding up one folded product automatically.
every fifty or one hundred of such products, so that the upper edge of such folded
product standing at an elevation facilitates the separation of the papers or products-
with the desired number in each pile.
18th. In this printing press, it is sometimes necessary to use webs of different:
widths, and when these are slit centrally and longitudinally and each half web.
folded longitudinally, it is necessary to adjust the positions of the longitudinal.
folders to suit the different widths of half webs so as to fold such half webs in the
middle. With this object in view, the frames carrying the longitudinal folders are
adjustable towards and from each other, such frames carrying not only the longi-
tudinal folders, but also the forwarding rollers that act with them; and to facilitate
the insertion of the web, these rollers are mounted in morable bearings so that one
roll in each pair of rolls can be drawn aside. laterally, and to effect these movements,
screw shafts with cones upon them to act upon the levers that carry the roller-
bearings are made use of, such screw shafts being geared together so as to be
rotated simultaneously in acting upon the different rolls.
19th. In some instances the three webs require to be split longitudinally and one
half web of each web folded around turning bars so as to bring the two halves of
the web one upon the other, and in this case the longitudinal folding inclines may
be placed one behind the other, either in line with one half of the split web or at
right angles thereto. This press is also adapted to collecting two or more sheets:
or folded products one upon the other and delivering the same to the folding-
mechanism that folds the collected products as one product previous to delivery
into the receptacle.
With this object in view, one or two collecting cylinders may be provided, there.
being grippers upon the collecting cylinder to grasp the advancing ends of the
sheets as they are pressed successively to the collecting cylinder.
20th. Sometimes the collecting cylinder has three sets of grippers, and within-
and eccentric thereto is a shaft and arms carrying two folding blades that act in
the middle of each sheet to fold the same outwardly between rollers, the arms and
blades revolving three times to two revolutions of the gripper cylinder, and when
one blade is thrown out of action, each set of grippers will take two sheets one-
over the other, before being delivered and folded, thus allowing the folded sheets
to be delivered single, or the folded sheets collected one on another before being
delivered and folded.
Figs. 1, 7, 17, 31, 35, 42 and 63 are diagrams illustrating the general positions of
the printing devices in the machines embodying the present invention.
Fig. 1 illustrates four rotary web presses, one above the other, and Figs. 7, 17,.
31, 35 and 63 illustrate three such presses, and Fig. 42 illustrates two of such.

page_text: presses; and it is to be understood that in all cases the paper is supplied from
rolls and drawn in and moved along through the respective presses in one general
direction, and the printed webs are brought together and associated either before
or after being cut into sheets and they are delivered as complete products and are
usually folded automatically before delivery.
In describing the first part of this invention, reference is made to Figs. 1, 17
and 21. In Fig. 1 there are arms O, O', 0 and 0 extending out at one end
of the frame, a portion of which frame is shown at L, and on the outer ends of
the arms 0, 02 and Os there are hinged arms connected by pivot bolts 14 and
provided with stops 15 that limit the downward movement, and the outer ends of
the arms 13 are preferably turned upward, and when a roll of paper is being lifted
by suitable means, such as by a platform upon the upper end of a hydraulic ram P,
the arms 13 are lifted, in succession and dropped, and when the roll that is being
lifted arrives at the proper place, the arms drop under the shait of the roll, and as
the lifter P is lowered, the roll of paper is received upon the arms 13 and rolled
along into position. The tube or bar 12 forms a shaft for the roll of paper and
projects at the ends so that the roll of paper can be rolled in between the frames
and one web joined to the other with rapidity so as only momentarily to stop
the printing operation. The rolls of paper are represented at A, A¹, A³, A', in
Fig. 1.
Fig. 3 shows a plan view of one of the arms; and it is to be understood that
the bottom arm O, may be at such a height as to receive the shaft of the paper
web as the same is rolled along upon the floor.
Second. In the form represented in Fig. 17, the brackets A' are hinged so as to
be swung out of the way of the roll of paper as the same is raised and then swung
in beneath the shaft of the same; and in Fig. 21 an overhead track 3 is repre-
sented with a hoistway such as a traveller, chain and yoke for suspending the roll
of paper Ras the same is brought along into position to be received upon the
stationary bracket 4, the swinging bracket A' being swung beneath the opposite
end of the roll shaft.
Third. To regulate the tension of the paper web as it is drawn off from the roll,
I provide suitable friction clamps D, D' shown in Figs. 4, 5 and 6, that act at
opposite sides of the friction wheel C upon the roll shaft B of the roll of paper A,
and at 2, Figs. 4 and a stationary stud is shown supporting one of the friction
clamps, and the nut 3 is employed for adjusting the friction by hand approximately
before starting the roll, and an automatic device is employed for varying the
friction by acting more or less upon the other clamp D¹.
The link S, Fig. 4, is acted upon by an eccentric and lever P and an automatic
connection Q for varying the pressure of the friction clamp. D', the lever P' and
link Q being pivotally connected at 4.
In Fig. 5, a nut. T is represented as acting upon a screw rod S, the nut T
receiving motion from a pair of, miter gears 5 and 6, one of which is moved by a
lever P¹ and a connection Q' to the automatic mechanism.
In Fig. 6 the clamps D' and D' are represented as acted upon by a rod and left
hand screw S receiving its motion from the bevel gears 5 and 6, the lever P and
an automatic connection Q.
In Fig. 63 the friction clamps D, D' are acted upon by an eccentric and link P
moved by a weight and lever P and link Q and a brush R lies against the circum-
ference of the roll and the friction is lessened automatically as the rell decreases
in size.
Fourth. The tension regulator and indicator-Before the web A' reaches the
roll and impression cylinder H it is represented in Figs. 4, 5 and 6 as passing
either over or under the rolls E, F, and the roll G is in a loop of a paper web and
carried by a suitable lever K, and the spring O tends to apply a yielding force by
the roll G to the web. If the web becomes too tight, the roll G moves the lever K
and the index M, showing upon the scale N that there is too much friction upon
the paper roll; and if the movement is the other way by the action of the spring O,

page_text: the indication is that more friction has to be applied. By the connection
from the lever K the friction is increased or decreased automatically of the clamps
upon the friction wheel of the paper roll.
In Fig. 31 the rolls 8 are mounted upon levers 9 pivoted at 10 and acted upon
by springs 12 and 14, and the index 24 at the end of the lever 9 enables the
attendant to adjust the friction applied to the paper roll; and it is advantageous
to have index boards 24" at suitable spaces with rods 23 leading to the same, so
that the attendant can more easily ascertain what adjustments are necessary upon
the friction devices as the paper is drawn off from the respective rolls.
In Fig. 35 the indicator 26 and scale 27 are acted upon by the roll 8 so that the
attendant is enabled to observe whether the paper is under the proper tension as it
passes through the press.
Fifth. Tension Adjuster. In printing machines where two or more webs are
running rapidly through two or more presses, and the webs are brought together,
it is important to maintain the proper tension upon the webs to aid in causing the
register of the printed pages to be accurate, and the attendant at the delivery end
of the machine has the opportunity to observe the register, but being at a distance
from the rolls of paper ordinarily could not adjust the friction upon such rolls.
To provide against this difficulty the device shown in Fig. 35 is made use of,
that is to say, hand wheels are applied upon shafts running from the friction devices
of the paper rolls to the end of the press, where the webs are brought together.
These hand wheels are represented at 23 upon small and long shafts passing
through a frame and provided with collars at each side of the frame and with
screws acting upon the friction clamps of the respective paper rolls. In this
instance the friction clamps 11 are in pairs with a hand adjustment 15 for each pair
of clamps, hence the preasure or friction can be regulated by the attendant acting
upon either hand wheel 23 adjacent to the paper rolls or at any suitable place
adjacent to the associating or folding apparatus of the press.
Sixth. The clamps 11 that apply friction to the wheels on the shafts B of, the
paper rolls A are advantageously lined with segments of wood 12, so as not to
develop unnecessary heat or to be injuriously affected by atmospheric conditions,
or by expansion or contraction.
The lining 12 aforesaid is shown in Figs. 31, 35 and 37.
Seventh. In connection with the seventh division of the present invention, it
will be apparent that the rolls 6, 7, 8, Fig. 1, and the arms for adjusting the same,
ensure the proper registration of the printed webs, and the slitter 55* on the
shaft 50x, Figs. 7, 17, 20 and 32, may be employed upon one or more of the webs
so that either the full width webs may be associated together or one web may be
carried over turners 43", 43" as illustrated in Figs. 17, 18 and 20, Sheet 6, so as to
associate the webs together or to bring a half web under or over a full web, and
where the folding inclines stand in opposite directions, as shown in Fig. 63,
Sheet 21, the intermediate web 2, may be slit and a half thereof pass under the full
web 1, and be folded upon the incline F and the other half web be passel under
the full web 3 and be folded with it upon the incline F.
Eighth. The rolls that receive the tapes or belts are advantageously made as
illustrated in Fig. 19, Sheet 6, that is to say, there is an annular depression with a
rounding or convex surface where each belt 14 travels, so that the surface of the
belt is in line, or nearly so, with the surface 117 of the roller 6.
I have found that when the tape rolls are made in this manner, the three or
more webs cling together as they are drawn along, and there is but little tendency
for the intermediate web or webs to fall behind in the register of the printed
matter. The two or more webs are caused to cling together as aforesaid, by
corrugations on the roll, whether tapes are used or not.
The roller 9 or the roller 10, Fig. 1 aud the roller 6, Fig. 17, and the rolls 9,
Fig. 38, over which the webs pass after they have been printed, may have annular
depressions with surfaces that are rounded or convex as aloresaid, and in Fig. 17,
the endless belts are represented that run upon the convex surfaces, the object
B

page_text: being in either case to prevent the intermediate webs becoming slack or out of
register as such webs are passed over such rolls to the folding portion of the
mechanism.
I have also found it advantageous to bring the webs together in such a manner
that the last printed surfaces of the webs will be outward so as to be exposed to
the atmosphere and lessen the risk of the impression becoming blurred when the
webs are either brought together or drawn over the folding incline.
Fig. 63 illustrates the manner in which the web 3, after being printed, is led
upward and the web 2 is brought downward, hence the surfaces that are last
printed upon by the type or plate cylinders E1 and E2 come outward, while the
surfaces that are first printed by the type cylinders B1 and B2 come toward each
other. Of course in this way of leading the webs as printed, care, is required in
properly placing the stereotype plates upon the cylinders so that the pages come
in the proper order.
Ninth. Longitudinal Folding Mechanism. The webs of paper pass upon a
longitudinal folder having edges that converge, as shown at G, Figs. 1, 7, 9, 11, 13
and 14, and at 17, Figs. 17, 18, 20, 22, 23, 24, 25 and 27, 29 and 30, also at F,
Figs. 32, 33, 38, 39, 42 and 43, and at F F Figs. 63, 64 and 65, and this folding
incline is at an angle io a pair of rolls or guides, so that as the web or webs pass
from one position to another they are folded double with a central longitudinal
fold.
In machines that have heretofore been made having a converging incline for
longitudinally folding the paper, difficulty has been experienced by the rolls or
guides adjacent to the apex of the incline pressing upon the paper at the fold and
causing it to crease or break, or to run irregularly. To avoid this difficulty, the
ends of these rolls do not extend to the apex of the incline, but stop short thereof
with conical or inclined ends, as seen at 18, Figs. 17, 18, 20, 22, 23, 24, 25, 26,
and at d, Figs. 12 and 13, and at G G Fig. 63, and the apex of the folding incline
advantageously extends down as low as the axes of the adjacent rolls or bars, or
slightly below the same, as indicated in Figs. 13, 14, 17, 18, 20, 22, 23, 25, 27, 29,
30, 33, 39, 42, 43, 64 and 66, and the extreme lower end or apex of the incline is
rounded, so also are the edges of the converging folder, as seen in Figs. 22, 23,
and 24, so that the paper will be folded with a central fold without the risk of
injury in the folding operation; and it is advantageous to place the rolls or bars
that are immediately adjacent to the apex of the folding incline comparatively
close together, and these may be used for drawing the web of paper along, but
usually a second set of rolls is employed for applying tension to the web or web,
as shown at 1, Fig. 1, at f, g, Figs. 9, 11 and 14, and at 19, Figs. 17, 25, 27, 29
and 30, and at ff, Figs. 42, 43, and at H H, Figs. 63, 65 and 66, and cutting or
perforating cylinders are employed for severing or perforating the web transversely,
as illustrated at K, Fig. 1, at H H, Figs. 7, 9, 11 and 39, at 20, and 21, Figs. 17,
25, 27 and 29, at 28, Fig. 33, at m n, Figs. 42 and 43, and at II, Figs. 63, 64,
65 and 66.
The perforating or cutting cylinders are of usual character, the same being
formed of a knife on one cylinder and a groove on the other, or a knife with points
or teeth on one cylinder and a groove on the other.
Where the longitudinal folding incline F is used as shown in Fig. 42, the bars t
are used to turn the webs at right angles to pass to the drawing rolls and cutting
cylinders that are parallel to the cylinders of the press, hence the printing machine
can be made compact and not require as much room lengthwise as the presses
shown in Figs. 1 and 7.
Tenth. Means for adjusting the folding rollers or guides. It is generally
advantageous to be able to move both the rolls de, Figs. 7, 9, 11 and 14, so as to
open them for passing in the end of the web, and by moving both rolls equally
they adapt themselves with facility to the thickness of the product going through
between them.
In Figs. 9 and 11, the axes of these rolls de, are carried by levers 60 61

page_text: pivoted at 62, 63, and connected by gear segments, and the spring 64 applies a
pressure to keep the rolls de toward each other, and the stop 66 determines the
proximity of these rolls, and a handle 65 is used to separate the rolls.
In Fig. 14, the levers 50 and 51 carry the axes of the rolls de, and the stop
at 57 regulates the proximity of these rolls, and a lever 55 upon the fulcrum 54
with links 52 and 53 are employed for drawing the rolls de apart, and the spring 56
serves to press them toward each other.
g
The rolls which act to draw the paper along after it has been folded longi-
tudinally are pressed together so as to apply the proper tension, and with this
object in view, a spring may be applied to the journal box of one of the rollers, as
shown in Fig. 14.
In Figs. 25, 26, 29 and 30 an arrangement of rolls or guides for drawing along
the folded web of paper and cutting the same off is represented, the same being
found convenient, especially on rapid presses.
In Fig. 29 the cutting cylinders are represented as mounted in journal boxes 45
in the frame K, and a screw 47 at each end is used to limit the approach of the
rolls toward each other, and the spring 46 presses one roll towards the other, and
the rolls 19 that draw the paper along are driven by an intermediate gear 73 to
one of the cutting cylinders, and one of the rolls 19 has stationary bearings for the
ends of its shaft, and the bearings for the shaft of the other roll are in bent
levers 51, and the bearings for one of the rolls 18 are fixed and for the other
roll 18 are in the bent levers 59, and the levers 59 and 51 are connected together
by an adjusting link 61, and the springs 52 act to force one roll in each pair
towards the other.
The shaft 62 is made with a screw 63 in the part 48 of the frame, see Fig. 25,
and it has near its ends the cones 65, and at one end is a hand wheel 64, so that by
revolving the hand wheel, the shaft and the cones, the cones may be moved
end wise, and in so doing they act upon the levers 51 to move such levers and
thereby primarily adjust the proximity of the rolls 19 and by the links 61 and
levers 59 regulate the proximity of the rolls 18.
If desired the adjusting devices can be arranged as shown in Figs. 26 and 30, in
which the shaft 62 and cones 65 are provided as before and acted upon by the
hand wheel 64, and the train of gearing 81 extends across to the second shaft 62
with cones 65 upon it, so that the two shafts are turned simultaneously. In this
case the second shaft is made to act directly upon the sliding bearing carrying one of
the rolls 18, such sliding bearing being in a support 60 and acted upon by a spring 52,
and the toe 82 is acted upon by one of the cones 65, it being understood that similar
devices are provided at each end of the shaft of the roll 18, as seen in Fig. 26.
The plate 53 which carries the bearing 56 for one roll 18 and the pivot for the
lever 59 that carries the other roll 18 may be adjustable vertically by the slots and
bolts 55 so as to raise and lower these rolls 18 in regard to the apex of the
longitudinal folder 17. This adjustment is sometimes advantageous according to
the number of webs that are to be folded together.
When the parts are arranged as in Fig. 30, the spring 52" acts upon the link 76
that is connected to the bent lever 51 and applies pressure by one roll 19 towards
the other roll 19, and the links 80 are acted upon by the cones 65.
In Fig. 25 the bar 67 supports the lower part of the longitudinal folding
incline 17, and the nuts 68 are employed for adjusting the parts to bring the end
of the folding incline into the right position for the rolls 18.
Eleventh. Two sets of folding inclines. In Fig. 17, two sets of folding inclines
are shown as standing in the same direction so as to allow for separating the webs
into two products. In Fig. 63 the two folding inclines stand in opposite directions,
or back to back, so as to pass the webs in one of two directions, or to pass some
portions of the printed webs in one direction and other portions in the other
direction so as to fold and deliver the products at two places, and Fig. 65
illustrates the same features as those shown in Fig. 63, with the exception that the
folding inclines, set back to back, are sufficiently close together for the rolls that

page_text: act upon the folded webs to extend across both folded products, and in this Fig. 65,
the webs can be directed from the roll 5 beneath either roll 6 or 13 at the upper
ends of the inclines F F so as to fold all the webs together upon either the
incline For the incline F', or one web may be directed beneath the roll 6 and the
other web beneath the roll 13, and the intermediate web 2 may be slit longitudinally
by the cutter 8 and half of the web passed under the web 3 upon the incline
and the other half of the web 2 under the web 1 and between the same and the
folding incline F. These arrangements give great facility in printing products
with different numbers of pages, as may be required from time to lime.
It is to be understood that the converging folder may be of any desired.
character, either as a plate or bars, or small rolls o, Fig. 66, may be employed over
which the web of paper is passed, and these rolls may be grooved similar to screw
threads and revolved rapidly by the gears p, so as to properly forward the web as
it is folded and draw out or remove any creases that might otherwise be formed.
1 find it sometimes advantageous to apply to the rolls that draw the paper off
the longitudinal folding incline, a frictional driving mechanism instead of gearing,
and to tighten the frictional mechanism more or less and thereby apply more or
less tension to the webs of paper as they are moved along. With this object in
view an endless belt 40, Fig. 14, is represented as passing around or in contact
with pulleys 42, 43, 44 and 45 upon the shafts of the rolls f, g, d, e, and this belt 40
also passes around a tightener 41 that can be set up more or less by a screw so as
to tighten or slacken the belt and thereby regulate the friction applied to drive the
respective rolls and through them to draw along the paper.
In Fig. 32 the lower web is shown as passing beneath the first folder so as to be
led up between the two folders to the second folder; and when this lower web is
slit longitudinally one half web may be carried up as shown by dotted lines and
folded longitudinally under the middle web,' and the other half web will be taken
to the second folder and folded longitudinally under the upper web.
Twelfth. Folding, cutting and associating. The before mentioned improvements
in the printing, associating and longitudinally folding of the webs, may be used in
connection with any ordinary folder that acts upon the sheets after they have been
cut off, but to adapt the present improvements to the different circumstances under
which they are used, I have illustrated in Fig. 66, that cylinders H may be
employed to draw the web along, such cylinders being notched or their surfaces.
removed at opposite sides so as to release the hold upon the paper at the moment
the cutter of the cylinders I acts upon the web, thereby using the cutter to tighten
the web upon the folding incline, and the same feature is illustrated in Fig. 64,
and the sets of belts 16 and 17 are shown as passing over the pulleys or rolls 14,
18, 15 and 19, and the belts 16 and 17 receive between them the web that has been
perforated by the cutters I, and a breaker-bar 20 comes into action against the
roll 18, the parts moving with an accelerated velocity sufficient to separate the
sheet or group of sheets from the web or webs.
In Fig. 64 the same parts are represented in connection with an imposing
cylinder K, the belts / serving to pass 'the separated product around such imposing
cylinder K, and there are grippers 29 for holding the advancing ends, and when
the switch 28 pivoted at 27 receives a motion and the grippers 29 are simultaneously
opened, the advancing end of the product is carried by the belts f up to the belts g
as they pass around the roll 25, and thence such product passes over the roll 21
and beneath the roll 26 to a suitable place of delivery. The guide rolls 23 and 24.
serve for guiding and tightening the belts f.
A breaker-bar 60, Fig. 39 is shown as acting against the roll 61 to give a sudden
movement to the sheets and separate them at the line of perforatious, the perforators
being shown at 30.
Thirteenth. Transverse folding mechanism. It is often desirable to fold the
associated sheets transversely and sometimes to deliver them separately and some-
times to associate them with another longitudinally folded product. In Fig. 39,
the sheets as separated by the breaker-bar 60 are carried along by the belts to the

page_text: rolls 43, and the folders 40 are in the form of blades pivoted centrally and at the
ends are acted upon by gears 41, within the stationary toothed ring 35, and these.
folders are carried around by arms upon a central shaft, and at the time the middle
of the sheets arrives at the rolls 43, one of the folders 40 in its revolution comes
into the position shown in Fig. 39, and folds the sheet downward so that it is
carried off by the revolving rolls 43.
A similar operation is illustrated in Fig. 11, in which the revolving folders L
upon the arms L' that are carried around by the shaft M act between the rolls 24, 29
to fold the center of the sheet downward hetween such revolving rolls, so that they
are delivered to the packer hereafter described.
In this Fig. 11, the longitudinally folded products, that are perforated trans-
versely by the cutting cylinders H, are carried by the belts downward, and the
breaker-bar & acts against the roll 16 to separate one product from the next, and
the belts carry the product up to the transverse folders L, the switch or guide K
being properly placed for effecting this object, but when the switch or guide K is
set in the other direction, the product passing from the folding incline G is taken
by the belts 27 and 28 beneath the roll 33 and up past the guide bars 34 and roll 16%,
and the parts are so timed that the advancing end of the product from the folding
incline G coincides with the advancing end of the product from the folding
incline G, the breaker-bar & serving to separate the product from the incline G
and the two products go on in register over the roll 23 and over the rolls 24*
and 29%, and the transverse folders L2 press the center of these sheets down between
such rolls 24 and 29 so that the products are folded together and delivered into
the receptacle N as hereafter specified..
It is advantageous to employ a revolving shaft R having a crank P¹ carrying
packers P, there being an arm P and a link Q to the frame to swing as the shaft R
revolves and by the crank Pl gives motion to the packers to cause the packers to
press the folded product along in the receptacle N, there being guide bars 32 that
are nearly vertical near which the folded products descend, and it is advantageous
to counterpoise the shaft R and packers by the weights, as shown in Fig. 11.
Upon the frame of the machine a camt is provided having a notch at one side
and the fingers S pivoted at S¹ extend across between the packers P and near the
bars 32. Ordinarily the cam keeps these fingers S depressed so that they are
out of the way, but when the cam t has been rotated, the spring t¹ causes the end
of the arm s to pass into a notch in the cam t and the ends of the fingers S to rise,
so that one product as it comes down is stopped upon these fingers, and being
pushed forward, remains at a level in the pile of signatures or folded products in
the receptacle N, and by providing gearing to rotate the cam t once for every fifty
or one hundred sheets delivered, the folded product or signature that remains at an
elevation can be used for taking off the products in piles of fifty or one hundred,
as may be desired.
Sometimes the folded products as they are folded transversely and carried down
between the rollers 32 and 35, Fig. 33, are received upon a slowly moving helt 46,
and the vibrating fingers 45 pivoted at 48 and actuated by a lever arin and link,
shown by dotted lines, and an eccentric upon the shaft of the cutter 28, are made
use of to press down the sheets in succession and cause them to lie one upon
the other as moved forward upon the belt. In this instance it is advantageous to
employ stationary bars 43 upon which the edges of the folded products slide down,
as seen in Fig. 34, the vibrating fingers 45 serving to press the folded products
down and cause then to pass clear of the bars 43. In Fig. 33 the transverse folder
is represented at 38.
By providing fingers 55 acted upon by a cam 58 that is moved along
progressively, the ends of the fingers 55 may be brought down upon the lower
portion of one of the folded products so that the next folded product as it is
delivered from the rolls 32, 35, is arrested in its downward movement so that the
upper end of such folded product projects as illustrated at 54, and by this means
the products are counted automatically.

page_text: The dotted circles in Figs. 10, 11, 27, 33 and 39, illustrate the gear wheels that
may be made use of in driving the respective parts in the right directions and
approximately at the proper speeds, but as these devices are well known to press
builders, they do not require further detailed description.
It is advantageous to employ springs P for forcing the folding rolls towards
each other and applying the proper pressure to the products or signatures as folded
and pressed through between them by the rotary folders L L, Fig. 11.
Referring to Fig. 27, it will be observed that rolls 27 and 28 are made use
of by which a folded web from one side of the delivery apparatus can be carried
over and associated with the folded web from the other side of the apparatus
before being cut off, so that the perforating cutters can act upon the two longi-
tudinally folded webs, or when the web 26 is not crossed over by being passed
over and under the rolls 27 and 28, each folded web may be carried on between the
perforating cylinders and separated by the breaker-bars 23 and rolls 24 and
delivered separately.
In Fig. 28 an imposing cylinder 25 with grippers is shown for carrying around
one or more of the products as separated by the breaker-bar 23, and then the sheets
upon the imposing cylinder are discharged by opening the grippers and moving the
bars 34 along endwise a sufficient distance to receive the advancing ends of the
sheets. The belts represented in Figs. 11, 27, 28 and 39 serve for directing
the products to the respective places of delivery.
Fourteenth. In illustrating the improvement to which the fourteenth part of
this invention heretofore referred to relates, it may be remarked that where a
printing machine contains two, three or more presses for printing webs of paper and
forwarding the same to a common point of association and delivery, if the webs
were simply laid one upon the other and then cut off, the devices before described
for regulating the tension upon the paper webs would be sufficient to maintain
accuracy of registration, so that the pages of printed matter would coincide, but in
machines of this character, there are elements that tend to disturb the accurate
register of the respective webs and cause one web to creep or move endwise in its
relation to the other web.
One of these disturbing causes is illustrated in Fig. 1, in which it will be apparent
that the four webs passing over the rolls 9 and 10, the outer and upper web will
draw the tightest, and the inner webs being on arcs of circles of less radius, will
not move along as fast as the outer and upper web, hence the outer and upper
web will gradually become further advanced than the lower or inner web. The
same condition exists where the webs pass over convex turning bars which are the
equivalent of rolls.
The before mentioned difficulty is augmented by the two or more webs passing
over converging inclines G, Figs. 1, 7, 8, 11 and 14, because the inner or under
. web will be exposed to the friction upon the surface of such converging incline
that folds the webs longitudinally. Should the under web from either or both of
the before mentioned causes be so detained that the upper web advances
only the 200dth part of an inch on each product, the printed matter would be
drawn out of register to the extent of one inch in 200 impressions. To counteract
the tendency before mentioned, I construct the lower printing press in such a
manner that it forwards a less length of web each revolution than the upper
printing press, hence the products remain in register and can be cut off jointly, and
the differences in the lengths of the sheets are not appreciable and the register is
maintained.
To illustrate this feature of the invention, Fig. 16 is a distorted diagram to
indicate that the impression cylinder C is smaller than the impression cylinder C,
as the object before mentioned can be accomplished by making either the
impression cylinders or the type cylinders in the various presses of the proper
relative sizes.
Where there are four presses, as illustrated in Fig. 1, it is preferable to make
the type cylinders in the different presses of the proper proportionate sizes, that is

page_text: to say, the diagram, Fig. 2, illustrates that the type cylinders B³ and E³ in the
top presses may be th of an inch larger in diameter than the type cylinders B
and E in the bottom press, and that the type cylinders in the intermediate presses
may be proportioned, the type cylinders B₁ and E¹ of the second press being
3th of an inch larger than the type cylinders B and E, and the type cylinders B
and E of the third press may be ths of an inch larger in diameter than the
type cylinders B and E of the bottom press. By this slight change in the diameter
of the cylinders of the respective presses, the before mentioned difficulty is
entirely overcome; and it is to be understood that the measurements before named
are only illustrative, and that the actual measurements will depend upon the
character of the paper to which the machine is adapted and also to the disturbing
influences that may act upon the paper webs after they have been printed.
It will be borne in mind that in presses of this general character the type or
printing plates are rolled up into cylindrical segments to fit the surfaces of the
type cylinders, and there are always spaces upon such type cylinders between
one ferm and the next, and these spaces will vary in the respective cylinders,
so that while the plate or type forms are of uniform length peripherally, the
distances in the lengths of the sheets will occur at the spaces between the printed
matter.
Having reference to the printing machine with three sets of presses, shown in
Sheet 3, and to that containing four presses, shown in Sheet One, I remark that it
is advantageous to apply the driving mechanism by bevel gears, as shown in Figs. 8
and 17, the bevel pinions b being upon a vertical shaft a, and the bevel wheels c, c' c
being upon the shafts of the impression cylinders B B1 B2, and by providing a
sleeve 3, upon the shaft of each cylinder, one of which is shown sectionally in
Fig. 15, the same being pinned on firmly, the bevel gear c, is held by a collar at
the end of the sleeve, but the parts can be adjusted, by loosening the clamp screw
so as to set the type cylinders in their proper relations to each other, and in Fig. 1,
Sheet One, a similar gear is represented as driven by the shaft F, and connecte 1
to the gearing in the folder so that the folding mechanism is properly moved
in its relation to the printing mechanism. In Fig. 1, the rolls 6, 7, 8 are
shown as upon arms by which the positions of the rolls can be varied to form
longer or shorter loops in the paper webs so as to bring them accurately into
register at the rolls 9 and 10 where they are associated together.
The inking mechanism may be of any desired character, and in Fig. I the type
cylinders are shown at B B B and B and E E' E2 and E³. The first impression
cylinders are shown at C C C and C³, and the second impression cylinders at D,
D' D' and D³.
In Fig. 7 the first type cylinders are shown at A, A1 and A2, and the second
type cylinders at D D' and D, there being intermediate impression cylinders B B¹
and B and C C1 C2, and in this Fig. 7 there are belts represented at 6, 7 and 8
for forwarding the webs and also vertical belts 20 21 for carrying up the lower
web to bring it in proper position to the other webs, and in this Fig. 7, the top
web passes over a roll 41 and the lower web over a roll 11, the intermediate web
passing over an intermediate roll, and the slitter 55* upon a shaft 50* may or may
not be used to divide one or more of the webs longitudinally.
Fifteenth. In connection with the seventh part of this invention, I have
heretofore described how a web may be slit longitudinally and one part of the half
web carried across and brought into register with the other half web, as seen in
Figs. 18 and 20; and it will be apparent in connection with these figures that the
half webs which are brought into register can be folded longitudinally on the
incline 17 and cut off together as one product; and in Fig. 27 the inclines 17
are illustrated as adapted to fold the products separately and longitudinally so
that they may be delivered either into separate receptacles or they may be
associated together after being folded longitudinally and cut off as one product.
Sixteenth. In connection with Fig. 27, I have heretofore described how the
webs as slit longitudinally and folded longitudinally can be associated together

page_text: by carrying one half web laterally and associating it with the other half web, and
this may also be done in connection with the folding devices represented in
Fig. 11, wherein a folded web from one side may be carried off from below the
rolls fg, to the cutting cylinders H' on the other side, as shown by the dotted
line z.
In Fig. 63, and as before described, the middle web 2, may be slit longitudinally
and associated with the whole web 3, and the whole web 1, as the whole webs are
folded longitudinally, after which the associated products are cut and folded or
otherwise treated.
Seventeenth. The device for packing the folded products into receptacles has
been partially described in connection with Figs. 11 and 33. In Fig. 39 the
folded sheets are represented as passing down between the rollers 43 that are above
the end of the trough or receptacle 56, in the bottom of which a belt 57, travelling
over rollers 46, carries the products along gradually within the trough, and the
vertical pushers 45 are upon cross shafts between wheels upon a shaft 48, so that
the shafts 47, of the packers 45, are carried around bodily, but the packers 45, are
kept up vertically by the action of gear wheels represented by dotted lines and as
receiving their motion from a stationary wheel 53, that acts upon the intermediate
wheels 54 that gear into the wheels 55, upon the shafts 47 of the packers 45, hence
these packers while standing vertical are carried bodily towards the folded products
as they drop and push them along into the receptacle 56, and then, the packers
draw down between one product and the next.
In this form of packing apparatus, the fingers 57 are brought into action
periodically by a cam 58 so as to hold up one product in, say every fifty or one
hundred products, and thereby facilitate the separation of the products into
packages containing the desired numbers of products. In Figs. 40 and 41 the
packers 45 and shafts 47 are represented as carried around by disks 49, and as
having crank arms 64 and pins or rollers running in the stationary cam groove 66,
so that such packers are held vertical while acting against the sheets or products
as delivered by the rolls 43.
In Fig. 39 an imposing cylinder K is represented with belts for passing the
sheets or signatures to the imposing cylinder, and with a switch 28 similar to
the devices shown in Fig. 64, so that two or more signatures or products can be
imposed before they are carried off to the folder 40 and rolls 43.
Eighteenth. In Figs. 25, 26, 29 and 30, I have illustrated the rolls 18, 19 and
incline 17 as carried by a frame K, and this frame can be adjusted bodily and
laterally by the screws 49, there being pins 50 in slides for supporting the parts
and allowing of this movement; and it is to be understood that by carrying these
parts bodily and laterally the apex of the folding incline 17 and the rolls that act
with it, can be moved a sufficient distance to adapt the press to different widths of
webs or half webs so as to bring the longitudinal folds to the proper middle
positions of the webs or half webs, and where there are two folding inclines, as
illustrated in Fig. 27, the frames before referred to are employed and can be
adjusted towards or from each other. To facilitate the insertion of the webs, the
rolls at the apex of the longitudinal folding inclines can be drawn aside laterally
by the levers shown in Figs. 9, 11 and 14, or the screws and cones 65 can be used
for moving the rolls laterally, as illustrated in Figs. 25, 26, 29 and 30, as before
set forth.
Nineteenth. If two, three or more webs are made use of and they require to be
split longitudinally, they can be laid one upon the other, as illustrated in Figs. 18
and 20 and the slitter 55* is employed to sever the webs longitudinally, and the
half webs on one side may be turned around turning bars or rollers 43", as
illustrated in Fig. 18, and brought to coincide with the other half webs and folded
longitudinally, or, if desired, the half webs may be carried off at right angles, as
seen in Fig. 20, and brought together and folded longitudinally, or one or more of
the split webs may be carried forward upon the inclines 17 that are in line with
such half webs and folded longitudinally before being cut off into signatures or

page_text: products. The sheets from two webs may be brought together and delivered as
one product, and the third web may be slit and brought together, folded, cut, and
delivered as another product.
The collecting or imposing cylinders that may be made use of in connection with
the before described improvements have already been referred to in connection
with Figs. 39 and 64, and these collecting or imposing cylinders are provided with
grippers and with switches for delivering the associated products.
Sheets 16 to 20 inclusive illustrate the twentieth division of my invention.
Two rotary web-perfecting printing presses are shown at U and L, of usual or
suitable construction, and a longitudinal folder F, to which the webs are led
around rollers and turners in a well-known manner. From the rollers ef of
the folder F the webs pass hetween the cutting-cylinders m n, where they are
severed into cuts or sheets. From this point the cuts pass to the devices of this
part of the present invention.
A rotatable carrier-cylinder C, formed of ends 2 3, Figs. 44 and 45, hoops 4,
and longitudinal ties 5 5 5, Fig. 43 is journaled on suitable studs or bearings 6
on the frame-work A. of the machine. The spaces a, b, c, between the ties permit
of the protrusion of suitable folding-blades. This cylinder is to be provided
with suitable sheet-retainers, as pins or grippers, the latter being shown at 7,
as coacting with the ties 5 5 5, to hold the leading or front edges of the
cuts.
The cylinder C is driven by means of the toothed gears 8 on or forming the
ends 2, 3, the gears 9 9 on the shaft 10, which is journaled in the framework A,
the gear 11 on a similarly journaled shaft 12, and the gear 13 on the side
shaft 14. The grippers 7 are opened at the proper times by suitable means, as
the movable cams 15 16, which are pivoted to the framework, as at 17, 18. These
cams 15, 16, are suitably operated from a convenient part of the machinery, as by
the rods 19 20, straps 21, 22, and eccentrics 23, 24 on shaft 12. The gears 9 11,
are in the proportion of one to two, and gears 9 8, are in the proportion of one to
three, whence it follows that shaft 12 makes one (1) turn to two-thirds (3) of a
turn of cylinder C, and that the cams 15, 16 are each alternately in and out of the
positions in which they open the grippers 7. This is their operation when sheets
are collected on cylinder C, it being understood that any set of grippers after being
opened to take a first sheet by the cam 15 is not opened by cam 16 until such set
passes that cam the second time. For this reason the eccentrics 23 24 are placed
at opposite sides of shaft 12. A set of tapes 25, running on rollers or pulleys 26
and guides 34, coact with cylinder C to hold the sheets thereto when collecting.
The sheets are guided to the grippers by cylinder C, by the guides or bars 27,
and the tapes 28 running on rollers or pulleys 29, and folding-roller 30. There is
a second-folding roller 31 for coaction with roller 30.
The folding blades az, are borne by shafts 35 which are journaled in arms 36
on a shaft 37. This shaft 37 is journaled in bearings in the studs 6, which are
eccentric to the center of rotation of cylinder C. The shaft 37 is driven by
means of gear 38 thereon and the gear 39 on shaft 10, which are in the pro-
portion of two to one. As the gears 98 for driving cylinder C are in the
proportion of one to three, it follows that one of the blades passes the
rollers 30 31 each time any of the spaces a b c pass the same; that is to say,
the rotations of the cylinders C and the shaft 37 are to each other as three
to two.
The blades are driven by means of the shafts 35; the gears 40, detachably
fastened to the studs 6 and having their centers coincident with the center of
shaft 37, and the gears 41, which are journaled on the arms 36, and the gears 42
on the shafts 35. The proportions of this gearing are such that each shaft 35 and
its blade make three rotations while making one revolution about shaft 37.
The gears 40 (or only one of them) are fastened to the studs 6 by means of the
pins 42', which pass through the gears 40 and into holes in the studs 6. The
arms 36 are provided with holes 43. By taking the pin 42 from the position in

page_text: which it locks a gear 40 to the stud 6 and
putting it through a hole in gear 40 and
into hole 43, that gear 40 is locked to the corresponding arm 36, and gives no
motion to the corresponding blade 2 or 2. Owing to the hoops 4, the blades az are
cut away, so as not to touch the same.
The sheets folded by the blades az and the rollers 30 31 are conveyed away by
the sets of tapes 28 32 (the former set running on rollers or pulleys 29 and roller 30
and the latter set running on roliers or pulleys 33 and roller 31) and the guide bars
or fingers 44 to the receiver R.
The cylinders m n are geared together and to the cylinder C by the gear
wheels 45, 46, 47 8. The rollers 30 31 are geared together by the gear
wheels 48 49 and to cylinder C by the wheels 50 51 8. The wheels 48, 49, 50, 51
are so proportioned that the surface speed of rollers 30 31 is greater than that of
the cylinder C, the purpose being to accelerate the speed of the sheets to allow the
grippers 7 to take the ends as they come from the cylinders m n without injury to
the sheet just ahead.
The forms or plates may be arranged on the plate cylinders of the presses in
any suitable manner, regard being had to the fact whether a longitudinal fold is or
is not to be given to the webs. In the case shown in the drawings there are to be
two forms circumferentially of each plate cylinder, of which one prints matter
belonging to an inside and the other form prints matter belonging to an outside
sheet. Such inside and outside sheets are indicated in Fig. 48 by the reference,
letters i o.
As
The operation of these parts will now be described, it being premised that the
blade is inoperative, the corresponding pin 42' being in the gear 40 and arm 36
(see Fig. 44), and reference being had to Figs. 42 to 58 inclusive. Referring to
Fig: 48 there is shown a web (or associated webs) which is given a longitudinal
fold along the central margin il, by the folder F and is cut transversely along the
margins indicated by the dotted lines k. Assuming for convenience that the
leading or end cut of the web in Fig. 48 is an inside sheet and that it is taken by
the grippers coacting with the plate 5, the position of the parts is that shown in
Fig. 49. The succeeding cut, an outside, is fed down in front of the folding-
rollers 30 31, and is folded off, as indicated in Figs. 50, 52, 54, 56 and 58.
stated above the positions of the cylinder in Figs. 49 to 58 inclusive, differ from
each other by one-third (3) of a rotation thereof. In Fig. 51 an inside sheet is on
tie-plate 5. In Fig. 52 occurs a folding of two cuts inside and outside from
tie-plate 5°. In Fig. 53 an inside sheet is on tie-plate 5, and in Fig. 54 an
outside and an inside sheet are folded off. It will be noted that the positions of
the parts in Fig. 43 are those corresponding to diagrammatic Figs. 50 and 56, and
that the arrangement and proportions of the various parts are such that the
operations thereof are indicated in Figs. 49 to 58 inclusive. Figs. 55 to 58
illustrate similar action of the parts. The reference letters a be in Fig. 48
indicate the tie-plates 5° 5° 5, on which the cuts come, while the numerals 11" 13"
15 17 indicate Figs. 52, 54, 56 and 58 wherein the collected cuts are shown as
being folded. It is understood, of course, that the grippers 7 are operated by
the mechanism hereinbefore described. The outside sheets need not be gripped
by the grippers 7, as they will be held by the cylinder C and roller 30, and the
tapes and guides shown sufficiently to prevent them 'from falling or getting out of
place.
The operation of the parts when both blades are in use is indicated in
Figs. 59 to 62 where every sheet is folded off. In this case the cam for operating
the grippers 7 to release sheets is or may be disconnected from the mechanism for
operating it and be fixed in position to open the grippers every time they pass it.
In the modification shown in Figs. 46 and 47 the cylinder is supported at one
end on a stud 6 and is open at the other end, which is supported and guided by the
antifriction rollers 52, which coact with one of the hoops 4. The bladesz z are
supported, as before described, but are operated by the fixed internal gear 53 and

page_text: gears 42 on shafts 35. By moving one of these gears 42 out of mesh with gear 53
the corresponding blade may be rendered inoperative. The operation of the parts
is the same as that hereinbefore described.
In place of using a folding blade that revolves on pivots, such blade x may be
fitted to slide as shown in Figs. 43' and 43, where it carries the fold of the sheet
in between the grippers 30x and a folding bar 31*; this sliding blade may be
actuated by cams 32* or by pivoted cams 34* on the frame moved by eccentrics 35*
to allow the blade to pass without being projected, or to project the same at
the proper time to carry the fold of the sheet in between the folding bar and
grippers.
The cam 32x can be rotated by the gearing a, and as indicated by dotted lines in
Fig. 431, the gear as being connected with the cam 32*, and the cylinder miy
have teeth at a so that said cylinder can be rotated by a gear a" on the same shaft
as a', and at the proper proportionate speed. If the cam 32* makes two revolutions
to one revolution of the cylinder C the sheets will be accumulated in pairs and
folded in the middle as they are carried off by the grippers 30 and 31*.
If the folders, Fig. 432 are fixtures, and the grippers 30x are held open alter-
nately, the sheets will be accumulated by the grippers as, and any desired number
can be accumulated before being carried off; and it will be observed in Fig. 432
that as the grippers open they press back the last end of the preceding sheet so as
to grasp the advancing end of the next sheet, and said sheet passes in between the
grippers and cylinder as the sheet travels at the same speed as the cylinder so as
to be caught by such grippers.
By varying the proportions or movements of the parts the devices shown in
Figs. 431 and 432 can be made to accumulate any desired number of sheets and
discharge them as they are folded together as one product in the middle.
