Improvements relating to Printing and Folding Machinery.
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 :-
These improvements are shown as embodied in that class of machines known as
vibrating folders, that is, such as have folding blades that vibrate in co-operation
with folding rollers, into the nip of which they introduce the sheet on the line of
intended fold; but other forms of folding devices may be employed.
The improvements, stated in general terms, may be said to consist :-
In combining with two sets of folding rollers and two folding blades, sheet-
carrying and controlling devices whereby four folds may be imparted to each
sheet;
In combining with two sets of folding rollers and two folding blades, means for
delivering a sheet once, twice, three, or four times folded ;
In conveying twice folded sheets from the secondary folding mechanisms to the
primary folding mechanisms;
In conveying twice-folded sheets from the secondary to the primary folding
mechanisms, and superimposing such folded sheets and an unfolded sheet;
In stripping two superimposed folded sheets, whereby one may be delivered, and
the other further folded;
In the combining of a folding machine with the fly-delivery apparatus of a printing
machine, and providing the same with means whereby sheets may be delivered flat,
or folded one or more times.
The invention comprehends other combinations and improvements fully herein-
after pointed out and claimed.
A practical means of delivering the printed sheets from a cylinder printing
machine either flat or folded, has long been a desideratum, and means have been
devised having this end in view.
In the present improvements, the folding machine is so combined with the printing
machine, as not to interfere with the usual operation of the means for delivering
the sheets from the printing machine flat upon a piling table, and yet provide for
such sheets being conveyed to the folding machine, all of which will be fully
understood from the following detailed description of a practical embodiment of
the invention.

A side, the opposite side will be called the D side, and the sides respectively at
the right and left hands of the A side, will be called the B and C sides, which
designating letters are applied to the drawings.
The principal elements of the folding machine are an upper folding blade 10,
that co-operates with folding rollers 2, 2, and a lower folding blade 9 that
co-operates with folding rollers 11 (see Fig. 4). The upper folding blade 10, and
its rollers 2, 2, are arranged parallel with the travel of the sheets as they run out
of the printing machine, while the lower folding blade 9 and its rollers 11, 11, are
arranged at right angles thereto.
The folding blade 10 works downward, and the folding blade 9 works upward in
performing the folding operation.
The folding rollers 2, 2 and 11, 11 are mounted in suitable bearings provided in
the framework. The rollers 2, 2 are provided, at one end (see Figs. 4 and 5), with
wheels 12, 13, by which they are geared to run in unison, while one of the rollers
carries a bevel pinion 14 gearing with a bevel-wheel 15 on the shaft 16 (see Fig. 5)
at the D side of the machine. This shaft 16 receives motion from the shaft 51 at
the C side of the machine, to which it is geared by bevel pinions 52, 53, said
shaft 51 being, in turn, geared by bevel wheels 54, 55, to, and driven by, the
carrying roller 60, which latter is, through a bevel pinion 56, driven by a side
shaft 161 from the printing machine.
The upper folding blade 10, which co-operates with the rollers 2, 2, is a narrow
knife-like blade, pivoted at its opposite ends to bell cranks 20, 21, mounted on
shafts 40, 41, whereby it is given a compound vertical and longitudinal movement in
the folding operation, and thus is made to travel with the paper during the beginning
of that operation.

page_text: Its actuating bell-cranks 20, 21 are connected together so as to move in unison by
a rod 22, and while the bell crank 20 may rock on or with the shaft 40, the bell
crank 21 is fast to the shaft 41, and the latter is rocked by a rock arm 42, that is
actuated by a cam 43, whose driving wheel 44 turns upon a stud, and is driven in
proper time by wheels 45, 46, the latter being upon one end of the main
carrying roller 60.
The lower folding blade 9, which co-operates with the rollers 11, 11 (see Figs. 15
and 16), is made up of two parts a, e, adjustable on the carrying bar 30, whereby
one part a may alone be in action, as in Fig. 15, or both parts a, e may be in
action, as in Fig. 8, or be out of action, as in Fig. 16. The carrying bar for this
folding blade is pivoted to bell cranks 31, 32, tied together by a rod 77, and
journaled on shafts 90, 100, and a reverse upward movement is imparted to the
said folding blade by means of a rock arm 29 fast on shaft 90 (see Fig. 3), and a
connecting rod 33 (supported by a swinging arm 34) and a cam 35 projecting from
the outer face of the wheel 44.
The means for conveying the sheets over the first folding rollers 2, 2, consists of
two sets of tapes, the upper set being best seen in Fig. 4, and the lower set in
Fig. 5.
The tapes 3, composing the upper set (see Fig. 4), run from pulleys on a shaft 61,
and return over pulleys carried by a shaft 62. Of the lower tapes 4, the central
ones run over the main carrying roller 60 (see Fig. 10), and the margin tapes run
over pulleys on a shaft 63 (see Fig. 9), while all of said tapes, after moving out
underneath the tape 3, return over pulleys on the shaft 16, pass under one and
over the other of the folding rollers 11, 11; thence under pulleys on a shaft 69, the
central tapes returning to the roller 60, and the margin tapes move in contact with
said roller 60, thence run over pulleys on a shaft 67, pass under pulleys on a
shaft 66, and return to the pulleys on the shaft 63. The roller 60 is driven and
the tape pulley shafts 16 and 62 are geared together by wheels 84, 85, thus causing
the tapes 3, 4 to be driven in unison, and the latter to drive the folding
rollers 11, 11. Acting to form a pathway with the tapes 4 from the folding
rollers 11, 11 to the pulleys on shaft 67, are auxiliary tapes 17, which run around
one folding roller 11, pass thence under pulleys on the shaft 69, bear against
roller 60, and return over pulleys on shafts 67, 68 and a roller 71, driving power
for said tapes being obtained from the roller 60 and pulley shaft 67, which are
geared together by wheels 72, 73. Co-operating with these tapes 3, 4, for
controlling the sheets over the rollers 2, 2, are thin bars 83, which are supported at
their outer ends by spring-like brackets rising from a shaft 86 (Fig. 10), and at
their inner ends by two of the conductors 57. The brackets which support the
outer ends of the bars 83, will yield sufficiently to permit the conductors 57 to be
adjusted to different positions, as will be hereinafter explained. To the upper and
under surfaces respectively of these bars 83, are secured stops or gauges 82, 99,
which stops 82 are arranged to intercept all sheets carried over the rollers 2, 2,
above the bars 83, while the stops 99 will intercept all sheets carried over the
rollers 2, 2, below the bars 83. The thin bars 83, instead of being secured at one
end to conductors 57, may be secured to a suitable bracket attached to the rod 70,
in which case said bars 83 would be placed so as to make suitable connection by
the side of the guard 57.
These conductors 57 are supported on a rock shaft 64, and on a rod 70 and all of
them (six being shown) co-operate with the tapes 6 in forming the entrance portion
of the main pathway for the sheets, and with the auxiliary tapes 17, in delivering
certain sheets over the pulleys on shaft 67. The conductors are slotted so as to
slide on the rod 70, and the shaft 64 passes through, and turns in their tail ends.
This shaft has excentric journals by which it is mounted to turn in bearings in the
side frames (see Fig. 17), and at one end is provided with a rock arm 87, by which
it may be rocked to positions fixed by means of a set screw. When the shaft 64 is
rocked so as to carry these conductors into their forward positions, as in Fig. 10,
the pathway from the rollers 11, 11 is continued over the pulleys on shaft 67, and

page_text: when the conductors are adjusted in their rearward position (as in Fig. 19), said
pathway is connected with the main pathway formed by the tapes 3, 4.
...A sheet-conducting pathway from the primary folding rollers 2, 2, to the
secondary folding rollers 11, 11, is formed of tapes 5, 6 (see Fig. 8). Of these the
tapes, 5 run around one roller 2, thence around the bending roller 50, thence
underneath the folding rollers 11, and return around pulleys on a shaft 91 and a
. roller 92. The tapes 6 running over the other folding roller 2, pass beneath the
companion folding roller 2, thence around the roller 50, thence underneath the
-folding roller 11, and return around pulleys on a shaft 93.
With these tapes are arranged guides 8, which are narrow bars extending from
the roller 50 (into recesses of which their curved ends project) outward beneath
the rollers 11, 11, and extend to a point beyond the pulleys on shafts 93, 91, where
their ends are curved down concentric with the pulleys on the latter shaft, with
which and the tapes 5 they form a delivery for some of the sheets.
The guides 8 are supported by brackets, as 26 (see Figs. 8 and 13), and between
these brackets 26 is a connecting bar 27, over which the central tapes 6 pass, so
that they are raised slightly higher than the margin tapes 6. The reason for this
is as follows:-
The guides
are supplied with gauges or stops 47, arranged to arrest sheets at
one point, and with a stop 48 arranged to arrest sheets at another point.
These stops are all constructed alike, and each consists of a shaft 19, to which
are attached fingers 7, long enough to extend across the pathway of the sheets.
This shaft 19 is capable of turning in journals rising from a base plate 23 (see
Figs. 13 and 14), which rests on top of the guides 8, and is provided with a notched
disc 28, at one end, with which co-acts a pawl 29 in retaining the fingers 7 in the
vertical position shown in Fig. 13, to act as stops, or in the raised or inoperative
position shown in Fig. 14.
.
The stops 47, 47 are so situated as not only to act to arrest wide sheets, but to
provide for the passage beyond them of narrow sheets, which latter the stops 48
act to arrest, or allow to pass, according as they may be adjusted, and both sets of
.stops may be arranged to admit the passage of the wide sheets.
To insure the arrest of said wide sheets, when narrow sheets folded with wide
sheets are to be stripped therefrom and separately delivered, as will be hereinafter
explained, and when paper of a delicate texture is manipulated, it has also been
found desirable to provide arresting devices for co-acting with the head stops 47,
and operating to bring the sheet to a state of rest, without buckling its forward
edge. One means for accomplishing this, may be sheet-arresting tail stops. As
shown, these are swinging toes or arms 75, that co-act with the guides 8. There
may be two or more of these toes 75, arranged on a common rock shaft, to which
motion is imparted by a rock arm and a cam in the usual manner. Other similar
means may be employed to effect the same result.
.
This folder is adapted to fold the product of an ordinary cylinder printing
machine, wherein sheets are printed and perfected by feeding them a second time,
the means for their flat delivery being an ordinary fly frame. The delivery end of
such a machine is shown in Fig. 1. Of its printing mechanism, only the impression
cylinder 94 is shown, but the feed board 95, by which the sheets are fed to the
printing mechanism, and the tapes 96, 97 whereby the printed sheets are delivered,
are illustrated. These delivery tapes 96, 97 convey the sheets between pulleys 78, 79,
and from thence they may descend onto tapes 88, before a fly frame 89, and be laid
upon a piling table 100.
The folder is arranged with respect to the delivery end of the printing machine
so that its pulley shafts 61, 63, are a slight distance in advance of the delivery
tape pulleys 78, 79, and its driving shaft 161 is actuated by a wheel 98 on the
shaft of the cylinder 94, through intermediates 35, 36, and bevel pinions 37, 38, the
gearing and the folding rollers 2, 2, and shaft 16, being preferably such as will
impart a slightly greater surface speed to that part of the folder, than that at
which the press runs, so that when the sheets are being folded, sufficient working

page_text: space may be provided between successive sheets. Between the delivery tapes of
the printing machine and the conveying tapes of the folder, is arranged a sheet-
conduit, that is capacitated to guide sheets to the folder or to the fly frame. This
consists of conductors 24, that are secured to a swinging shaft 58, hung by rock
arms 74 to the shaft 78, and they have suitably-shaped ends that respectively enter
the spaces between the pulleys on the shafts 63, 78, and, when arranged as is best
seen in Fig. 11, these conductors continue the pathway of the sheets from the
tapes 96, 97, to the tapes 3, 4, and thus guide sheets from the printing machine
into the folder. These conductors may also act to guide the sheets to the fly when
they are to be piled flat, and for this purpose are rocked into the position shown
in Fig. 12. In order to ensure more positively this guiding action to the fly
frame, a guide plate 49 is employed, which is curved to coincide with the curved
rear ends of the conductors 24, when the two are in the position shown in Fig. 12.
This guide plate (see Fig. 4) carries, at each end, an arm 18, that, at the rear, is
jointed to an arm 59 on the shaft 79, and at the front is jointed to an arm 76, said
arms 76 and 74 forming a toggle lever. By this construction, the movement of the
conductors 24 downward, carries with them the plate 49, and holds the same by
frictional resistance in the relation they have in Fig. 12, wherein they constitute a
pathway to guide the sheets from the tapes 96, 97, down before the fly frame.
contrary movement will carry these devices into the relation shown in Fig. 11,
where they form a pathway to guide the sheets from the tapes 96, 97 to the
tapes 3, 4.
A.
It is practical to omit the plate 49 and its connecting devices, by constructing
the conductors as shown in Fig. 18, where the conductors 24 are mounted on a rock
shaft, and have their ends curred, so that by a slight tilting of them, the two
conducting operations will be performed.
Where the sheets vary in size, the folder may be adjusted to operate upon
smaller ones by moving the gauges or stops 82, 99, and 47, 48, which are made
adjustable on the bars 83 and conductors 8 for that purpose.
This once-
Assuming the conductors 24 to be adjusted, as shown in Fig. 11, the fingers 7
of the stops 47 and 48, and blade 9, as shown in Figs. 8 and 15, the conductors 57
as shown in Fig. 19, the operation will be as follows:-Each successive sheet will
be delivered to, and carried by the tapes 3, 4, outward over the folding rollers 2, 2,
until its leading edge is arrested by the stops 82. The folding blade 10 will then
descend, and fold said sheet by doubling it on the line (Fig. 28) into the nip of
said folding rollers. As it emerges from these folding rollers 2, the once-folded
sheet will be conveyed by the tapes 5, around the roller 50, and be carried
underneath the rollers 11 and above the folding blade 9, and against the fingers 7
of the stops 47, which course is indicated by dotted lines in Fig. 22.
folded sheet will then be folded by the blade 9 between the folding rollers 11,
passing between which, it will be a second time folded on the line o (Fig. 29) at
right angles to the first fold. As it emerges from the rollers 11, this sheet, which
has been so reduced in width by the first fold as to extend between only the four
pairs of tapes 17-4, at the centre of the machine, will be carried rearward, and
directed around the roller 60 (see Fig. 23), by the conductors 37, and again entered
above the folding rollers 2, but beneath the guides 83, it being arrested by means
of stops 99 on said guides in proper position (see Fig. 24) to be a third time folded
on the line of Fig. 30 by the folding blade 10. As the feed of sheets to the
folder is constant, it follows, by the proper timing of the mechanisms, that when
the twice folded sheet, as in Fig. 30, passes beneath the guides 83 and takes its
position above the folding rollers 2, an unfolded sheet will be simultaneously entered
from the printing machine over said folding rollers, so that the two sheets, one a
twice folded sheet and the other an unfolded sheet, will be superimposed between
the tapes 3, 4, as in Fig. 24, the guides 83 separating them. These sheets will
then bear the relation to each other shown in Fig. 31, where the dotted lines
represent the folded sheet beneath the unfolded sheet. Now, when the folding
blade 10 again descends, it doubles the superimposed sheets simultaneously, on the
: 0

page_text: line of Fig. 31, between the folding rollers 2, 2, and the two sheets are folded
together as in Fig. 32, as they pass between said rollers 2, 2.
The secondary folding mechanism operates immediately after the primary folding
mechanism, and it therefore follows, since the unfolded sheets are fed in regular
succession to the primary folding mechanism, that the first and third sheets and the
second and fourth sheets are the ones superimposed and folded together, and that
when the primary folding mechanism is operating upon the superimposed second
and fourth sheets, the secondary mechanism is operating upon the first and third
sheets, of which, said third sheet is to be superimposed with the incoming fifth
sheet, while the said first sheet is to be delivered as will presently appear.
The superimposed folded sheets, as in Fig. 32, pass outward beneath the folding
rollers 11, and above the folding blade 9 (see Fig. 26), and the once-folded sheet is
arrested by contact with the stops 47 (see Fig. 4), while the three-times folded
sheet, not meeting with obstruction at the point where the stops 47 are located, but
embraced between the centre tapes 5, 6, is carried onward by them until arrested
by the stops 48 (see Figs. 4 & 27). The separated once and thrice folded sheets
are thus made to occupy the relative positions respectively shown in Figs. 33, 34,
which positions they reach before the folding operation is accomplished by the
folding blade 9, and when this folding blade 9 operates, its section a doubles the
once-folded sheet, and its section e doubles the thrice-folded sheet simultaneously
into the nip of the rollers 11, passing between which, the once-folded sheet is
doubled a second time, as in Fig. 30, and the thrice-folded sheet is doubled a fourth
time, as in Fig. 35.
The twice-folded sheet is conveyed by the tapes 17, 4, and conductors 57, around
the roller 60, and again enters above the folding rollers 2, and beneath the
guides 83, where it is superimposed with an unfolded sheet, the same as already
described. The four-times folded sheet being within the embrace of only the two
margin tapes 4, 17, at the C side of the machine, is not directed over roller 60 by
the conductors 57, but is delivered from between the tapes 4, 17, over the
pulleys 67, and may there be delivered a completed product by any convenient
means. Thus, each successive, sheet receives four folds, the first and third, and the
second and fourth of which, are simultaneously made by the folding devices:
If it is desired to impart but one fold to the sheets, the folding blade 9 is put out
of action by adjusting it as in Fig. 16, and the stops 47, 48 are thrown out of action
as in Fig. 14. Thereupon each sheet, once folded through the rollers 2, 2, passes
around the roller 50, and is conveyed by the tapes 5, 6, and guides 8, over the
pulleys 91, at the C side of the machine, and may there be delivered by a fly, or
any other ordinary means of piling sheets. If it is desired to impart but. two folds
to each sheet, the a portion of the folding blade 9 is adjusted into active position,
as shown in Fig. 15, and the stops 47 are adjusted to arrest said sheet. The
conductors 57 are then adjusted in their forward position, as shown in Fig. 10, so as
to direct the sheets downward over the pulleys 67, whereupon the twice-folded
sheet will be delivered from said pulleys, and may be laid by any common piling
mechanism. If it is desired to impart but three folds to a sheet, the folding blade 9
has its e portion thrown out of action, as in Fig. 15. The stops 47 remain in action,
and the stops 48 are thrown out of action, and the conductors 57 adjusted as in
Fig. 19. The sheet, once folded between the rollers 2, is conveyed beneath the
folding rollers 11, there receives its second fold, as before described, passes around
the roller 60, enters a second time above the rollers 2, receives its third fold
simultaneously with the imparting of the first fold to an unfolded sheet, the two
sheets passing from the rollers 2 and beneath the rollers 11 are stripped apart, as
before described, and the thrice-folded sheet, instead of being arrested by the
stops 48, to be a fourth time folded by the part e of the folding blade 9, passes
onward between the tapes 5, 6, and guides 8, and is delivered at the C side of the
machine. These once and twice folded sheets will be delivered at the A side of the
machine, and may be laid by an arrangement of the fly of the printing machine
upon the piling table of that machine. The thrice and four times folded sheets are

page_text: delivered at the C side of the machine, and may be laid by a fly arranged at that
side of the machine, as in Fig. 1, upon the same piling table.
Thus, with two sets of the folding mechanisms, and two delivery conduits, sheets
may be folded one, two, three, or four times, and be delivered. The arrangement
of the fly frame 225 for delivering the once and three times folded sheets, differs in
no material sense from the structure commonly employed. It is vibrated, in the
instance illustrated, by means of a rock shaft 101, which carries fingers, and which
is vibrated by means of bevel pinions 102, 103, a rock arm 104, and a rod 105, cam-
actuated, or otherwise reciprocated, to produce this result.
As here shown, the printing press fly not only delivers the sheets from the
printing press flat upon the table 100, but may vibrate to its fullest extent to pile
both the twice and four times folded sheets upon that table. As the four times
folded sheets are quite small, it may be desirable to pile them at a point nearer
their delivery from the folding machine, and for that purpose Fig. 20 illustrates
such four-times folded sheets as delivered upon a hanging frame 200 by the fly
frame 89, supported in part by a bracket 201. This frame 200 is arranged to be
detached when the fly is to deliver sheets flat, and, for cooperation with it, such of
the fingers of the fly frame 89 as are abreast the passageway for the four-times
folded sheet, are hung to their shaft by springs, as shown in Figs. 20 and 21, the
attachment being such that the fingers are normally pressed forward, and held so as
to remain aligned with the other fingers, but may be arrested during a forward
movement, when brought into contact with the bar 201 of the frame 200, while the
remaining fingers continue their forward movement, as when flying sheets flat.
the return movement of the fly, the fingers again come into alignment with a
stop 202 on the fly frame shaft, and cause it to take up the spring pressure thereon,
and thus move all the fly fingers back to their normal position.
In
Of course the folding blades, though here described as of the vibrating type,
may have substituted for them other means for projecting them into the nip of
their folding rollers, thus a rotary mechanism now well understood in this art,
could be substituted; an air blast might be the equivalent of a blade; in short,
any of the means co-acting with rollers for doubling sheets into rollers, or equivalent
co-acting devices, might be substituted for the mechanism herein shown.
It will be observed that the folding rollers and their co-acting folding blades,
and also the principal bending rollers, are adjustably secured to the framework.
Also, that the rollers 2, 2, are provided with elastic bands that form their nipping
points; by their action, the folded sheet which is in contact with their surfaces in
the process of folding, is caused to enter the nip of the rolls slightly in advance of
the other sheet, and the separation of the sheets is made more certain. To avoid
confusion, these bands are only shown in Figs. 9 and 10. This separation of the
sheets may be aided by co-acting nipping rolls embracing centre tapes with tail
stop.
When sheets receive their first impression, if it is desired to deliver them flat
upon the piling table 100, the pinion 35 may be removed to render the folding
machine inoperative. When it is desired to connect the folding machine with the
printing machine, so that both shall cooperate to print and fold sheets, as when
the sheets receive their last impression, and are to be folded, the cylinder 94 will
be turned until the bed or "form" has been moved to a predetermined position,
and the cam wheel 44 of the folding machine will also be turned to a given
position, to bring the folding and printing mechanism into proper co-relation, when
the pinion 35 will be moved on its stud to mesh with the wheels 98 and 36.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, as communicated to me from
abroad, I declare that what I claim is :-
1. The combination with the delivery of a printing machine and the delivery
of a folding machine, of a fly frame adapted to pile sheets from either, and ineans

page_text: substantially as described for conveying sheets from the printing machine to the
folder, or directly to said fly frame, substantially as described.
2. The combination with a pair of folding rolls and a folding blade, of sheet-
conveying devices arranged to take the folded sheet from the rolls, carry it around
the ends of the rolls, and return it in position to be again folded between the rolls.
by the same blade, substantially as described.
3. In a folding machine, the combination with two pairs of folding rolls and two
folding blades arranged to operate successively upon the sheet, of sheet-conveying
devices arranged to take the folded sheet from the first rolls and present it to the
second rolls and blade, to receive a second fold, and take it from the second rolls
and re-present it to the first rolls and blade, to receive a third fold, substantially as
described.
