Improvements relating to Printing and Folding Machinery.
1, HENRY EDWARD NEWTON of "The Office for Patents," 6 Bream's Buildings,
Chancery Lane, in the County of London, Patent Agent, do hereby declare the
nature of this invention to be as follows:-
This invention relates to a folding mechanism which is especially designed and
adapted to be combined with a printing mechanism of the class known as a
cylinder press."
It is the object of the invention to produce a combined press and folding
mechanism in which the several parts shall be so constructed and organized, that
the entire folding mechanism will be located under the feed board or table of the
press and in the path which the sheets take in ordinary cylinder presses in passing
from the impression cylinder to the fly. By this means the combined press and
folder is made to occupy no more space than that occupied by the press alone.
A combined press and folding mechanism of this character will be capacitated, by
very slight adjustments, to deliver the sheets either in an unfolded condition, or
folded to different dimensions,-
-as once folded or twice folded,-and in all cases by
the same fly or piling mechanism.
A folding mechanism of this character will be so constructed and organised that
it can be applied to presses already in existence without the necessity of making
material alterations in their organisation.
The folding mechanism is located directly beneath the feed board, and between
the impression cylinder and the fly, and is so arranged that when the sheets are to
be folded, they may be operated upon by the folding mechanism as they pass
from the impression cylinder to the fly, without departing substantially from their
usual path of travel.
The folding mechanism may consist of two pairs of folding rolls and two
vibrating folding blades, which operate to fold the sheets into the bite of the rolls
in the usual manner. The first pair of rolls are arranged at right angles to the
impression cylinder, and midway of its length; are suitably supported, and are
geared together in the usual manner, and receive motion in any convenient manner.
The second pair of folding rolls is arranged parallel with the impression cylinder,
and below, and at right angles to the first pair, about midway of their length, and
extend from the first pair outward to one side of the machine. These rolls are
mounted upon, shafts which extend transversely between the side frames, and are
also driven by a belt suitably arranged.
One folding blade is connected to arms extending from a pair of transverse rock
shafts provided with arms which are connected by a horizontal rod. One shaft is.
also provided with an arm which is connected to a rod having a spring, the tendency
of which is to rock the shafts so as to hold the blade in its raised position. The other
of the shafts is provided with an arm, to which is pivoted a vertical rod which is
bifurcated at its lower end, and straddles the main shaft, and is provided with a
stud or bowl which is acted on by a cam on the main shaft, in such manner as to
depress the blade at the proper time to fold each sheet into the bite of the first
pair of rolls. The arm is mounted loosely on the second shaft, but is arranged to be
rigidly connected thereto by means of a sleeve provided with a clutch formed with
an operating handle, which extends outward at the side of the machine, so that by

page_text: pulling and pushing upon the handle, the sleeve can be moved along the shaft, so as
to lock and release the arm to and from the shaft, and thus throw the folding blade
into and out of operation.
The other folding blade is secured to arms extending from a transverse rock
shaft which is provided with an arm to which is pivoted a vertical rod, the
lower end of which is bifurcated and straddles the main shaft, and is provided
with a stud or bowl which is acted on by a cam in such manner as to hold the
blade in its raised position, except at such times as the blade is required to
be depressed, to fold the sheets into the bite of the second pair of rolls. The
downward movement of the blade, to accomplish the folding, is effected by means
of a spring in such manner as to rock the shaft and depress the blade. The arm is
mounted and operated in a similar manuer to that described with reference to the
other blade.
The folding mechanism is provided with five sets or series of sheet-conveying
tapes, which operate to take the sheets from the impression cylinder, and convey
them either directly to the fly in an unfolded condition, or to the first folding rolls,
and thence to the fly, after being once folded, or to the first folding rolls; thence
to the second folding rolls, and thence to the fly, after being twice folded.
In addition to the tapes above referred to, there are also provided the usual
narrow tape or tapes, which pass around the middle of the impression cylinder,
at the point where the blank space usually occurs between the printed pages of
the sheet.
Directly above the first folding rolls, are located a pair of stationary guides,
which serve to support the sheets at their centres, as they pass forward above the
folding rolls.
Series of stationary guides are provided to coöperate with some of the sets of
tapes.
The folding mechanism is also provided with two sets of adjustable stops for
arresting the sheets at the proper points for the folding operation. One set are
arranged at or near the forward ends of the first folding rolls, and are mounted
upon a transverse rock shaft, which is provided with an arm by which it can be
rocked so as to raise the stops when desired. The other set are arranged at or
near the outer ends of the second folding rolls, and are mounted upon the rod which
supports the guides.
The folding mechanism is provided with a slitter, by which the sheets may, when
desired, be divided at their centres, or on the line of the first fold.
The first folding blade is provided upon its opposite sides with a number of light
spring fingers, which are curved to conform to the curvature of the first folding
rolls.
The fly is of substantially the usual construction, except that those of its fingers
which are in front of the second folding rolls and the pulleys, are cut away,, so as
to provide au opening through which the ends of certain of the stationary guides
project. The fly is operated to pile the sheets by means of the usual spring, which
acts upon the arm of the fly shaft, and is returned to, and held in its raised position
in the usual manner.
The operation of the mechanism thus organised is as follows:-The sheets fed
from the feed board will be taken by the grippers of the impression cylinder, and
presented to the "form" to be printed in the usual manner. After being printed,
the sheets will be directed off the cylinder by the tapes. If it is desired to deliver
the sheets in an unfolded condition, as, for example, when they are passed
through the press the first time, and are only printed on one side, the stops will be
raised out of the path of the sheets, the folding blades will be thrown out of
operation, and, if it is not desired to divide the sheets longitudinally, the slitter
will be raised out of operative position.
If it should be desired, instead of delivering the sheets in an unfolded condition,
to deliver them with one fold, stops will be lowered into position, and a folding
blade be rendered operative.

page_text: If it should be desired, instead of delivering the sheets with one fold, to deliver
them, with two folds, two folding blades will be rendered operative.
It is sometimes desirable that the sheets, particularly when they are printed for
an eight-page paper, should be divided along the line between the heads of the
printed pages, which is the line upon which the first fold is usually made. If, in
any case, it should be desired to do this, the slitter will be lowered into position to
divide the sheets as they pass. The divided sheets can then be delivered in an
unfolded condition, the same as already described, or the two halves of each divided
sheet may be associated by directing their adjacent edges simultaneously into the
bite of the first folding rolls. For this purpose, the first folding blade is provided
with the spring fingers before referred to. If the two halves of the sheet are to be
associated in this manner, the stops will be lowered into position, and the folding
blade will be put into operation. The blade, as it descends, will pass between the
halves of the sheet, but the spring fingers will press the adjacent edges of the two
halves of the sheet against the folding rolls, so that they will be drawn into the
bite of the rolls, and be associated in passing between the rolls. To make it more
certain that the halves of the sheet will be drawn into the bite of the rolls, when
their edges are pressed against the rolls by the fingers, the rolls are provided with
rubber rings, which serve to give the rolls a better hold upon the paper. By this
operation, the sheets are in effect folded longitudinally, the saine as first described,
but in addition to being folded, they are cut or divided on the fold line. After
passing between the folding rolls, the sheets may be delivered without further
folding, or be folded between the rolls, and thus delivered the same as already
described.
The organisation which has been described embodies the invention in its most
complete and desirable form, but in some cases it may not be desired to give the
machine so great a range of capacity as has been described. If this should be
desired, it can be done, and yet retain many of the important features of the
invention. For example, if it should not be desired to capacitate the machine to
impart two folds to the sheet, the second folding rolls, blade, with the tapes and
guides, and the opening in the fly may be omitted. In such case, the sheets may be
delivered in an unfolded condition, or with one fold, in the same manner as already
described:
It is usually preferable, in a machine of this character, that the first fold, when
the sheets are to be folded, should be made longitudinally of the sheet, that is to
say, in the direction of its travel as it leaves the impression cylinder. For this
reason, the first folding rolls and first blade in the construction already described,
are arranged at right angles to the impression cylinder. This, however, is not
necessary, and may not always be desirable, as in some cases may be preferable
to have the first fold made transversely of the sheet. When it is desired that the
first fold should be a transverse one, the first folding rolls will be arranged parallel
with, instead of at right angles to the impression cylinder, and the positions of
other parts will be modified to the altered circumstances, or some of the parts may
be omitted.
By means of the organisation herein described, a combined cylinder press and
folding mechanism is provided, which occupies no more room than that occupied by
the press alone; the folding mechanism is located entirely beneath the feed board
of the press so as to be covered and protected, and by which the sheets can be
delivered either in an unfolded or folded condition to the same fly, which fly is
located in the usual position, and without substantial departure from the path of
travel which they ordinarily take in those machines which are not provided with a
folding mechanism, in passing from the impression cylinder to the fly. The folding
mechanism is so organised that it is combined with the press without the necessity
of making any substantial change in the general construction of the latter, thereby
making it practicable to combine the folding mechanism with presses already in
existence at a comparatively small outlay.

page_text: The principal parts of the delivery apparatus found in the ordinary cylinder
press remain practically unchanged, and can be readily utilized.
'
In the construction above described, the sheets are folded downward from
the tapes.
There are cases, however, in which it is desirable that the sheets should be folded
as they are passed through the press for the first time, that is to say, after they
have been printed on only one side, and should be folded upward from the tapes.
This is the case in producing what are known as "patent insides," where the papers
for a large number of small publishers are printed upon side at a general office,
and are then distributed among the small offices to be printed upon the other side
with local matter and news. In producing these "patent insides," it is frequently
desirable that the sheets should be folded once before being sent to the small
offices. Such folding not only reduces the sheets to more convenient dimensions
for carriage, but makes it possible to print the remaining side of the sheets upon a
comparatively small press. When, therefore, the sheets are to be folded after only
the first side has been printed, it is necessary, in order that the printing of the
second side inay be readily accomplished, that the folding should be so done that
the side first printed will be upon the inside of the folded sheet.
By arranging the first rolls above, and the first blade below the path of the
sheet, the printed side of the sheet, or the side last printed, is brought next the
folding blade, and is consequently upon the inside of the sheet after folding.
The operation of this mechanism will be on the same lines as that already
described, whether it is desired to deliver the sheets in an unfolded, or once or twice
folded condition.
A slightly modified form of machine, which is capacitated by slight adjustment
to fold the sheets with the printed side either upon the inside or outside will now
be described.
The first folding rolls and first folding blade, are mounted in the same manner,
and actuated by substantially the same mechanism, as in the construction last
described, except that the blade is placed above the rolls, so as to fold the sheets
downward.
The machine is provided with five sets or series of co-operating sheet conveying
tapes, suitably arranged, and with vibrating pulleys.
The folding mechanism thus organised is provided with three sets of stops. All
of these stops will be made adjustable, so that their positions may be varied.
The operation of the combined press and folding mechanism thus organised, is as
follows: If it is desired to deliver the sheets in an unfolded condition, the folding
blade remains idle, and in its raised position; the stops will be removed from the
path of the sheets, and switches will be set in position to direct the sheets. The
vibrating pulleys may also, if desired, be secured in their raised position.
If, on the other hand, it is desired to deliver the sheets in a folded condition,
the folding blade is put into operation, the switches will be set in position, and the
pulleys raised so as to allow of their being vibrated, and if it is desired that the
side of the sheet last printed shall be upon the outside of the sheet after it is
folded, the first set of stops will be lowered to position.
If it is desired that the sheet should be so folded that the side of the sheet last
printed will be upon the inside of the folded sheet, the adjustments will be the same,
except that the first set of stops will be raised, and the movements of the folding
blade properly timed.
In this case, the sheets are so presented to the folding rolls, that when they are
folded, the side of the sheet last printed is upon the inside of the folded sheet.
If, in any case, it should not be desired to capacitate the machine to deliver the
sheets in an unfolded condition, as, for example, when the machine is to be used
exclusively for printing "patent insides," or for printing the second side of the
sheets, the switches may be nrade stationary, instead of movable, or they may be
omitted, the arrangement of the tapes being slightly modified.

page_text: Or if, in any case, it should not be desired to capacitate the machine to fold the
sheets, so that the side last printed will be upon the outside of the folded sheet, the
first set of stops may be omitted.

Improvements relating to Printing and Folding Machinery.
I HENRY EDWARD NEWTOx of the Office for Patents, 6 Bream's Buildings,
Chancery Lane in the County of London, Patent Agent, do hereby, declare the
nature of this invention and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement:-
:
This invention relates to that class of printing presses employing a reciprocating
type bed in combination with one or more impression cylinders, and generally
known as cylinder presses.
The general object of the invention is to provide a combined cylinder press and
folding machine so constructed and organized that the space above the path of
movement of the bed, at the delivery end of the machine, may be utilized for the
folding mechanism, and this mechanism brought closely adjacent to the cylinder
from which the printed sheet is delivered. In cylinder presses of the common form
employing the usual feed board or table, it is thus rendered possible to place the
entire folding mechanism in the space under the feed board or table, so that
the combined press and folder occupies no more space than that occupied by the .
press alone.
A further object of the invention, is to provide such a combined press and
folding mechanism which shall be capacitated to deliver the sheets either in au
unfolded condition, or folded to different dimensions, as once folded or twice folded,
and further to provide such a construction in which the sheets unfolded or thus
folded to different dimensions, inay be delivered in all cases by the same fly or other
piling mechanism.
A further object of the invention is to provide a folding mechanisin so constructed
and organized, that it can be combined with cylinder presses already in existence,
without the necessity of making material alterations in their organization.
As a full understanding of the invention can be best imparted by a detailed
description of the construction and organization of the mechanism embodying the
same, all further preliminary description will be omitted, and a full description given,
after which some of the principal advantages gained by the organization will be
explained, and its novel features particularly pointed out and claimed.
It will be understood that the present invention is applicable generally to
printing presses of the class above referred to, employing a reciprocating type
bed, and one or more impression cylinders, of which class there are many sub-
classes, but for the purpose of illustration, the invention will be shown in
connection with a single-cylinder press of common form, employing a single
impression cylinder, to which the sheets are fed twice from a feed board for
perfecting, with which construction special advantages are obtained.

Figs. 20 and 21 are diagrammatic views illustrating the arrangement of the
tapes by which the sheets are conveyed from the impression cylinder to the fly.
Referring to said drawings, it is to be understood that A represents a portion
of the frame-work; B the reciprocating bed, C the form, D the impression
cylinder, E the feed board or table, and F the fly frame of an ordinary cylinder
printing press. The bed B is provided with any of the ordinary connections (not
shown), by which it is reciprocated in the usual manner, and the cylinder D is also
driven in any of the common ways, so as to rotate in unison with the bed, at the
time the impression is taken. The cylinder is also provided with the usual sheet
grippers (not shown), for holding the sheets to the cylinder during the printing
operation. The feed board E is arranged in the usual, or substantially the usual,
position, above and at one side of the impression cylinder, and the fly F is arranged
beneath the outer end of the feed board, as is also usual.
The folding mechanism is located directly beneath the feed board, and between
the impression cylinder and the fly, and is so arranged that when the sheets
are to be folded, they may be operated upon by the folding mechanism as they pass
from the impression cylinder to the fly, without departing substantially from their
usual path of travel.
Referring now particularly to Figs. 1 to 6, it is to be understood that, as therein
illustrated, the folding mechanism proper consists of two pairs of folding rolls 49, 41,
and two vibrating folding blades 42, 43, which operate to fold the sheets into the
bite of the rolls in the usual manner. The rolls 40 are arranged at right angles to
the impression cylinder D, and midway of its length. They are supported at their
..inner ends in brackets 9 (see Fig. 2), rising from a beam a, which extends trans-
versely between the side frames A, and their outer ends in brackets 8 (see Fig. 5),
rising from a rod b, which also extends transversely between the side frames.
These folding rolls are geared together in the usual manner, and receive motion
from a bevel gear 18, upon the shaft of one of the rolls (see Fig. 2), which engages
with a similar gear 10 upon the transverse shaft 39, which carries the usual delivery
pulley or roll 54, and is geared to the impression cylinder. The folding rolls 41
are arranged parallel with the impression cylinder, and below and at right angles
to the rolls 40, about midway of their length (see Figs. 2 and 6), and extend from
the rolls 40 outward to one side of the machine. These rolls are mounted upon
shafts which extend transversely between the side frames, and are also driven
directly from the shaft 39 of the delivery pulleys by a belt 38, which passes
around a pulley upon said shaft; thence between pulleys upon the shafts of the
rolls 1 (see Figs. 2 and 4), thence around a pulley upon the shaft of the usual

page_text: tape pulleys or roll 44, which will be hereinafter more particularly referred to,
and returns beneath a stretching pulley 37.
The folding blade 42 is connected to arms 11 extending from a pair of transverse
rock shafts 45, which shafts are also provided with arms 12, which are connected
by a horizontal rod 46. One of the shafts 45 is also provided with an arm 13,
which is connected to a rod 36, having a spring 35, the tendency of which is to
rock the shafts 45, so as to hold the blade 42 in its raised position. The other of
the shafts 45 is provided with an arm 14, to which is pivoted a vertical rod 47,
which is bifurcated at its lower end, and straddles the main shaft 99, and is
provided with a stud or bowl, which is acted on by a cam 48 on the main shaft in
such manner as to depress the blade 42 at the proper time, to fold each sheet into
the bite of the rolls 40. The arm 14 is mounted loosely on the shaft 45, but is
arranged to be rigidly connected thereto by means of a sleeve 34 (see Fig. 7),
which is splined to the shaft, so as to slide freely thereon, and is provided with a
tongue 15, which enters a corresponding recess in the hub of the arm 14.
clutch thus formed is provided with an operating handle 33, which extends out-
ward at the side of the machine, and is provided with a fork 16, which rests in a
circumferential groove formed in the sleeve 34. From this arrangement, it results,
that by pulling and pushing upon the handle 33, the sleeve 34 can be moved along
the shaft 45, so as to lock and release the arm 14 to and from the shaft, and thus
throw the folding blade 42 into and out of operation. When the arm is not locked
to the shaft 45, the blade 42 will be held in its raised position by the spring 35.
The operating handle 33 is provided with a set screw 17, by which it can be secured,
so as to hold the sleeve 34 in either position to which it is moved.
The
The folding blade 43 is secured to arms 32 extending from a transverse rock
shaft 49, which is supported in brackets 19 extending from the beam a. The shaft 49
is provided with an arm 50, to which is pivoted a vertical rod 51, the lower end
of which is bifurcated, and stradles the main shaft 99, and is provided with a stud
or bowl which is acted on by a cam 52, in such manner as to hold the blade 43
in its raised position, except at such times as the blade is required to be depressed
to fold the sheets into the bite of the, rolls 41. The downward movement. of the
blade 43, to accomplish the folding, is effected by means of a spring 53, which is
arranged to act upon the rod 51 in such manner as to rock the shaft 49, and depress
the blade 43, when, by the movement of the cam 52, it is permitted to do so.
arm 50 is mounted loosely upon the shaft 49, but is arranged to be rigidly
connected to the shaft by means of a sleeve 31 (see Fig. 8), which is constructed
and arranged the same as the sleeve 34 upon the shaft 45 already described, and
is provided with an operating handle 31 similar to the handle 33. When the arm 50
is not clutched to the shaft 49, the blade 43 will be held in its raised position
by any suitable means, as by a hook 98, depending from the feed board.
The
The folding mechanism thus organized, is provided with five seats or series of
sheet-conveying tapes 2, 3, 4, 5, 6, which operate to take the sheets from the
impression cylinder, and convey them either directly to the fly, in an unfolded
condition, or to the folding rolls 40, and thence to the fly after being once folded,
or to the folding rolls 40, thence to the folding rolls 41, and thence to the Hy,
after being twice folded.
These tapes are arranged as follows:-The series 2, 3 correspond to, and are
arranged in substantially the same manner as the ordinary conveying tapes with
which this class of cylinder printing machines are usually provided, to convey the
sheets from the impression cylinder to the fly. The series 2 pass between the
delivery pulley 54, and the usual series of co-operating pulleys 55, which are
mounted loosely upon a shaft 56, located above the shaft of the delivery pulleys,
thence forward above the folding rolls 40, and over the tape roll 44 before referred
to, which is located above the upper end of the fly; thence around a roll 57,. and
upward around stretching pulleys 5S. From the pulleys 58, all of these tapes
except the two marginal ones return directly around the pulleys 55. The two
marginal tapes of the series pass beneath a rod 59, and thence around the impression

page_text: cylinder D, near its ends, returning over the pulleys 54. The series of tapes 3 pass
around the delivery pulleys 54, and thence forward with the tapes 2 around the
roll 44. From the roll 44, the tapes upon one side of the folding rolls 40 return
directly to the pulleys 54 in the usual manner, while those upon the other side of
the rolls return over a roll 30, the shaft of which is supported at its outer end in
the side frame A, and at its inner end in a branch (see Fig. 5) of one of the
brackets 8. The series of tapes 4 pass over one of the folding rolls 40 (see Fig. 6),
and downward between the rolls, thence beneath the other of the rolls, and outward
to the side of the machine; thence around a series of pulleys 60, and inward,
returning around stretching pulleys 61. The series of tapes 5 pass around a series
of pulleys 20 mounted loosely on a shaft 21, which is located directly below the
roll 30, and is mounted rigidly in the end of arms 22 extending from the rod b, and
return around a roll 23. The series of tapes 6 pass around the outer one of the
folding rolls 41, thence downward, at an incline, above a roll 62, one end of which
is supported in the side frame A, while its other end is supported in an arm 63,
depending from the rod b, and returning around pulleys 54, which are supported
on arms extending from a shaft 68, located above the roll 62, and supported in the
same manner as said roll. It is to be remarked that pulleys 64, instead of being
supported on separate arms, may be supported on a shaft suitably arranged for
that purpose. In addition to the various tapes already referred to, there are also
provided the usual narrow tape or tapes 7, which pass around the middle of the
impression cylinder at the point where the blank space usually occurs between the
printed pages of the sheet, thence above the central one of the pulleys 54, and
around the corresponding one of the pulleys 55.
Directly above the folding rolls 40 are located a pair of stationary guides 29,
which are supported upon the brackets 8, 9, and serve to support the sheets at
their centres, as they pass forward above the folding rolls.
Located above the tapes 4, and arranged to co-operate therewith, are a series of
stationary guides 28 (see Fig. 6), which extend from the folding rolls 40, outward
to the side of the machine, and are supported upon rods 65, 66.
Located above the
tapes 5, and arranged to co-operate therewith, are a series of stationary guides 27
(see Fig. 4), which extend from the roll 30 forward, and turn downward over the
roll 23. These guides are provided at their outer ends with upward extensions 24,
which bridge the space between the rolls 44 23. Located between and beneath
the tapes 6, and arranged to co-operate therewith, are a series of stationary guides 26
(see Fig. 4), which are supported upon a rod 67, and extend from the folding
rolls 41, forward and downward to a point beyond the pulleys 64. Located above
the guides 26, and arranged to co-operate therewith, are a second series of stationary
guides 25, which are supported upon the rod 68, and extend from a point above the
roll 62, forward and downward, and terminate with the guides 26.
The folding mechanism is also provided with two sets of adjustable stops 69, 70,
for arresting the sheets at the proper points for the folding operation. The set 69
are arranged at or near the forward ends of the folding rolls 40, and are mounted
upon a transverse rock shaft 71, which is provided with an arm 72, by which it can
be rocked, so as to raise the stops when required. The set 70 are arranged at or
near the outer ends of the folding rolls 41, and are mounted upon the rod 65, which
supports the guides 28.
The hub of one of the arms 22, in which the shaft 21 carrying the pulleys 20 is
mounted is provided with an arm 73, the end of which is provided with a swiveled
eye bolt, through which extends the end of a rod 74, having a head at its cud,
between which and the eye bolt is located a spring 88. The opposite end of the
rod 74 is provided with a yoke which embraces a stud on the end of an arm 75,
extending from the hub of the arm 50, which operates the folding blade 43.
The folding mechanism, as shown in the present case, is provided with a slitter 76,
by which the sheets may, when desired, be divided at their centres, or on the line
of the first fold. This slitter is arranged over the central one of the pulleys 54,
and between the tapes 7, and is mounted upon the end of a shaft 77, supported in

page_text: arms 78, which are rigidly fixed to the shaft 56. The shaft 56 is provided with an
arm 79, by which it may be rocked, so as to raise the slitter, and render it inopera-
tive when desired. The shaft 77 upon which the slitter is mounted, is provided
with gear 80, which, when the slitter is in its operative position, engages with a
gear 81 upon the shaft 39, and thus gives a positive movement to the slitter.
The folding blade 42 is provided upon its opposite sides with a number of light
spring fingers 1, which are curved to conform to the curvature of the folding
rolls 40, as shown. The purpose of these fingers will be made clear, when the
operation of the apparatus is explained. The roll 23 is driven by means of a
belt 89, which passes around pulleys upon the shafts of the rolls 44, 23.
The fly F is of substantially the usual construction, except that those of its
fingers which are in front of the folding rolls 41 and the pulleys 64, are cut away
(see Figs. 3 and 4), so as to provide an opening through which the ends of the
guides 25, 26 project. The portions of the fly fingers which are above the opening/
are supported upon a cross bar 82, which is secured to some of the uncut fingers.
The fly F is operated to pile the sheets by means of the usual spring (not shown),
which acts upon the arm 83 of the fly shaft, and is returned to, and held in its
raised position, by means of the usual arm 84, connecting rod 85, and cam 86.
The operation of the mechanism thus organized is as follows. The sheets fed
from the feed board E, will be taken by the grippers of the impression cylinder D,
aud presented to the form C, to be printed in the usual manner.
After being
printed, the sheets will be directed off the cylinder by the marginal tapes 2 and the
tapes 7, and into the control of the tapes 2, 3. If it is desired to deliver the sheets
in an unfolded condition, as, for example, when they are passed through the press
the first time, and are only printed on one side, the shaft 71 will be rocked to, and
secured in such position as to raise the stops 69 out of the path of the sheets; the
sleeve 34 will be moved so as to disconnect the arm 14 from the shaft 45, and thus
render the folding blade 42 idle; the sleeve 31 will be shifted so as to disconnect
the arm 50 from the shaft 49, and thus render the folding blade 43 idle; and the
blade will be secured in its raised position; the yoke of the rod 74 will be dis-
connected from the arm 75, and hooked onto a stationary stud 87, provided for
that purpose, so as to hold the pulleys 20 in the position shown, and if it is not
desired to divide the sheets longitudinally, the shaft 56 will be rocked, so as to
raise the slitter 76 out of operative position, and disconnect the gear 80 from the
gear 81. The sheets will then, as they are directed off the cylinder, be carried
forward by the tapes 2, 3, above the guides 29, until they arrive at the roll 44,
after which they will be directed downward, and will emerge from between the
rolls 44, 57, and pass downward in front of the guides 24 and the fly, and be piled
in a flat or unfolded condition, having taken exactly the path of travel which the
sheets usually take in a printing machine of this class, in passing from the
impression cylinder to the fly.
If it should be desired, instead of delivering the sheets in an unfolded condition,
to deliver them with one fold, the stops 49 will be lowered to the position shown,
the sleeve 34 will be shifted so as to connect the arm 14 to the shaft 45, and thus
render the folding blade 42 operative, and the yoke of the rod 74 will be connected
to the arm 75, as shown; the sheet will then, as they are directed off the impression
cylinder, be carried forward by the tapes 2, 3, and above the guides 29, until they
arrive at the stops 69. The parts will be so timed, that as each sheet arrives at
the stops 69, the blade 42 will be quickly depressed, so as to double the sheet into
the bite of the rolls 40, thus folding it longitudinally upon its central line. After
being thus folded, the sheet will be carried outward between the tapes 4 and the
guides 28, until its folded edge arrives at the stops 70 at the side of the machine.
It will be observed that the stops 69 are so positioned that the leading edge of
the sheet, or what, after the first fold, becomes one of its sides, will, as the
sheet is carried outward between the tapes and guides 28. project beneath the
roll 30, and above the pulleys 20. The parts will be so timed that, as the sheet
arrives at the stops 70, as just explained, the cam 52 will arrive in position to
B

page_text: permit the spring 53 to rock the arm 50, and, through the arm 75, rod 74, and
arm 73, rock the arms 22, so as to carry the pulleys 20 upward into biting
contact with the roll 30. The side of the sheet, or what now again becomes its
leading end, and which, as explained, projects between the roll 30 and pulleys 20,
will thus be taken by the roll 30 and the tapes 5, and carried forward beneath
the guides 27, and over the roll 23, where it will be directed downward by the
curved ends of the guides in front of the fly, and be delivered in its once folded
condition.
If it should be desired, instead of delivering the sheets with one fold, to deliver
them with two folds, the adjustments will be the same at last described, except that
the sleeve 31 will he shifted so as to connect the arm 50 to the shaft 49, so as to
render the folding blade 43 operative, and the yoke of the rod 74 will be dis-
connected from the arm 75, and hooked onto stud 87. The sheets then, as they
arrive at the stops 70, instead of passing into the control of the roll 30 and tapes 5,
will be doubled into the bite of the folding rolls 41 by the blade 43, thus receiving
a second fold at right angles to the one imparted by the blade 42 and rolls 40.
As the twice-folded sheets emerge from the folding rolls 41, they will be carried
forward above the guides 26 and roll 62 by the tapes 6, and projected forward and
downward between the guides 25, 26, and through the opening in front of the fly,
and be piled in a twice folded condition.
It is sometimes desirable that the sheets, particularly when they are printed for
an eight-page paper, should be divided along the line between the heads of the
printed pages, which is the line upon which the first fold is usually made. If, in
any case, it should be desired to do this, the shaft 56 will be rocked so as to lower
the slitter 76 to the position shown, which will bring it into position to divide the
sheets as they pass the pulleys 54. When the slitter is in this position, the
gear 80 will engage with the gear 81, so as to properly drive the slitter.
The divided sheets can then be delivered in an unfolded condition, the same as
already described, or the two halves of each divided sheet may be associated by
directing their adjacent edges simultaneously into the bite of the folding rolls 40.
For this purpose, the folding blade 42 is provided with the spring fingers 1 before
referred to.
If the two halves of the sheet are to be associated in this manner, the
stops will be lowered to the position shown, and the folding blade 42 will be put
into operation. The blade 42, as it descends, will pass between the halves of the
sheet, but the spring fingers 1 will press the adjacent edges of the two halves of
the sheet against the folding rolls, so that they will be drawn into the bite of the
rolls, and be associated in passing between the rolls. To make it more certain that
the halves of the sheet will be drawn into the bite of the rolls, when their edges
are pressed against the rolls by the fingers, the rolls are provided with rubber
rings c, which serve to give the rolls a better hold upon the paper.
By this
operation, the sheets are, in effect, folded longitudinally the same as first described,
but in addition to being folded, they are cut or divided on the fold line. After
passing between the folding rolls 40, the sheets may be delivered without further
folding, or be folded between the rolls 41, and thus delivered the same as already
described.
The organization which has been described embodies the invention in its most
complete and desirable form, but in some cases it may not be desired to give the
machine so great a range of capacity as has been described. If this should be
desired, it can be done, and yet retain many of the important features of the
invention. For example, if it should not be desired to capacitate the machine to
impart two folds to the sheet, the folding rolls 41, blade 43, tapes 6, and
guides 25-26, and the opening in the fly, may be omitted. In such case, the
sheets may be delivered in an unfolded condition, or with one fold, in the same
manner as already described. Or the pulleys 20, and the connections for operating
them, may be omitted, and in such case, the sheets may be delivered either in an
unfolded condition, or with two folds, in the same manner as already described.
It is usually preferable, in a machine of this character, that the first fold, when

page_text: the sheets are to be folded, should be made longitudinally of the sheet, that is to
say, in the direction of its travel, as it leaves the impression cylinder. For this
reason, the folding rolls 40 and blade 42, in the construction already described, are
arranged at right angles to the impression cylinder. This, however, is not necessary,
and may not always be desirable, as in some cases it may be preferable to have
the first fold made transversely of the sheet. When it is desired that the first fold
should be a transverse one, the folding rolls 40 will be arranged parallel with,
instead of at right angles to, the impression cylinder.
In Figure 9, an organization of this character is illustrated, which is capacitated
to deliver the sheets either in an unfolded condition or with one fold, the single
fold being a transverse instead of a longitudinal one. In this organization, the
folding rolls 40 are arranged parallel with the impression cylinder, and are driven
in any suitable manner, but preferably by a belt arranged similar to the belt 38.
The blade 42 is mounted upon arms 11, extending from a rock shaft 45, extending
transversely between the side frames. The shaft 45 is provided with an arm 14,
which is connected to the shaft by a clutch, and is operated in the same manner as
already described. The blade 42 is in this case cut away, or recessed, so as to
permit the passage of the tapes 2. The tapes 2 are arranged the same as already
described. The tapes 3, instead of passing from the pulleys 54 directly to the
roll 44, pass downward between the folding rolls 40, and thence to the roll 44, and
then return around the roll or pulleys 23. The tapes 4-5-6 are dispensed with,
and the space between the outer one of the rolls 40 and the roll 44 is bridged by
guides 94, which co-operate with the tapes 2 and 3. The inner one of the rolls 40
is provided with a number of circumferential grooves, in which rest horizontally
moving guides 92, which are connected to a transverse rod, which is supported in
arms 91, extending from a rock shaft 96, which is mounted in brackets 93, projecting
from the beam a. The shaft 96 is also provided with an arm 97, to which is
pivotted a rod 90, the other end of which is acted on by a cam on the main shaft,
in such manner as to rock the shaft 96, and move the guides inward from the position
shown by full lines, to the position shown by dotted lines, at regular intervals.
The movement of the guides 92 in the reverse direction, and the upward movement
of the blade 42, is effected by means of suitably arranged springs (not shown).
The arm 97 is mounted loosely upon the shaft 96, but is arranged to be secured to
the shaft by means of a clutch similar to those hereinbefore described.
The operation of the mechanism, when thus organized, is as follows:-
When the sheets are to be delivered in an unfolded condition, the arms 14-97 will
be disconnected from the shafts 45-90, so as to allow the blade 42 to remain in its
raised position, and the guides 92 in their forward position, and the stops 69 will
be raised out of the path of the sheets. The sheets will then, as they pass forward
between the tapes 2-3, be directed past the rolls 40 by the guides 92, and will pass
forward between the tapes 2 and guides 94, and be projected downward from the
rolls 44-57 in front of the fly, and be piled in an unfolded condition. When it is
desired to impart one fold to the sheet, the stops 69 will be lowered to the position
shown, and the arms 14-97 will be connected to the shafts 45-96. The parts will
be so timed, that as, or just before, the leading end of each sheet arrives at the
stops 69, the guides 92 will be moved inward from the position shown by full lines,
to the position shown by dotted lines, and will be held in that position until the
sheet has passed between the folding rolls. As the leading end of each sheet
arrives at the stops 69, the blade 42 will be vibrated quickly downward, so as to
fold the sheet between the rolls 40. After passing between the rolls 40, the sheets
will be carried forward and upward between the tapes 3 and guides 94, and will
then be projected downward from between the rolls 44-57, in front of the fly, and
be piled in a once folded condition.
The mechanism thus organized, may readily be capicitated to impart two folds
as well as one, by providing it with a second pair of folding rolls and a second
folding blade, similar to the rolls and blade 41-43, and arrauged at right angles to
the rolls and blade 40-42, and with a roll and set of vibrating pulleys, similar to

page_text: the roll and pulleys 30-20, which will act to take the sheets and forward them
to the fly after they have received their second fold.
By means of the organization herein shown and described, a combined cylinder
press and folding mechanism of the class shown, is provided, which occupies no
more room than that occupied by the press alone, in which the folding mechanism
is located entirely beneath the feed board of the press, so as to be covered and
protected, and by which the sheets can be delivered either in an unfolded or folded
condition to the same fly, which fly is located in the usual position, and without
substantial departure from the path of travel which they ordinarily take in those
machines which are not provided with a folding mechanism, in passing from the
impression cylinder to the fly.
It will be understood, however, that the present invention is applicable also to
other classes of cylinder presses not employing a feed board, and that, while it is
preferable that the special folding mechanism shown and described, delivering
folded sheets at the same point as unfolded, be used, for convenience and economy
of floor space, and such a construction forms a part of the present invention, this
feature is not absolutely essential, and the present invention is not to be limited
thereto. It will be understood, also, that the invention is not limited to a
construction capacitated to deliver the sheets folded or unfolded, as it may be
embodied in a construction delivering only folded sheets.
It will be observed that the folding mechanism shown is so arranged that it may
he combined with an ordinary cylinder press, without the necessity of making any
substantial change in the general construction of the latter, thereby making it
practicable to combine this folding mechanism with presses already in existence, at
a comparatively small outlay, and this construction forms a part of the invention,
although it will be understood that this feature is not essential to the invention
broadly considered.
It will also be observed that the folding mechanism may be so combined with the
printing mechanism, that the principal parts of the delivery apparatus found in the
ordinary cylinder press, remain practically unchanged, and can be readily utilized.
For example, the cylinder from which the printed sheet is delivered and the fly
remain in the same position with relation to each other, and the delivery pulleys 54,
their co-operating pulleys 55, the tape roll 44, and the tapes 2-3, are the same or
substantially the same as in an ordinary machine, and perform the same functions.
Although the various series of tapes are shown as passing around pulleys in some
cases and rolls in other cases, it is to be understood that this is not material, as rolls
may be used in place of the pulleys, or pulleys in place of the rolls.
In the construction above described, the sheets are folded downward from the
tapes. There are cases, however, in which it is desirable that the sheets should be
folded as they are pressed through the press for the first time, that is to say, after
they have been printed on only one side, and should be folded upward from the
tapes. This is the case in producing what are known as "patent insides," where
the papers for a large number of small publishers are printed upon one side at a
general office, and are then distributed among the small offices, to be printed upon
the other side with local matter and news. In producing these "patent insides," it
is frequently desirable that the sheets should be folded once before being shipped to
the small offices. Such folding not only reduces the sheet to more convenient
dimensions for shipment, but makes it possible to print the remaining side of the
sheets pou a comparatively small press. When, therefore, the sheets are to be
folded after only the first side has been printed, it is necessary, in order that the
printing of the second side may be readily accomplished, that the folding should be
so done that the side first printed will be upon the inside of the folded sheet.
The present invention has for a further object, the provision of such a combined
press and folding mechanism, capacitated to deliver the sheets either in an unfolded
condition or folded with the first fold upward, and wherein the sheets, unfolded, or
thus folded, may be delivered in all cases by the same fly or other piling
mechanism. By arranging the rolls 40 above and the blade 42 below the path of

page_text: the sheet, the printed side of the sheet, or the side last printed, is brought next the
folding blade, and is consequently upon the inside of the sheet after folding, and in
Figures 10 to 16, such a construction is shewn, which will now be described.
The rolls 40 are arranged at right angles to the impression cylinder, as before,
supported at their inner ends by a transverse bar a', and at their outer ends by a
similar bar 6. These rolls are geared together, and receive motion from a bevel
gear 12, upon the shaft of one of the rolls, which engages with a similar gear 13"
upon a transverse shaft 39ª having a gear 14 which receives motion from the
impression cylinder through gears 15", 16" mounted respectively on the shafts 37, 38
of the usual delivery pulleys or rolls. The folding blade 42 in the figures now
referred to, is arranged below the folding rolls 40, and is connected to arms 11°
extending from a pair of transverse rock shafts 41", which shafts are also provided
with arms 10" which are connected by a horizontale rod 43, whereby both shafts
are moved in unison. One of the shafts 41" is provided with an arm 17" which is
connected to a rod 36 having a spring 35, the tendency of which is to rock the
shafts 41" so as to hold the blade 42 in its lowered position away from the rolls 40.
The other of the shafts 41 is provided with an arm 9 to which is pivotted a
vertical rod 44, which is bifurcated at its lower end, and straddles the main
shaft 99, and is provided with a bowl which is acted on by a cam 45" on the main
shaft, in such manner as to raise the blade 42 at the proper time to fold each sheet
into the bite of the rolls 40. The arm 9ª is mounted loosely on the shaft 41ª, but
is arranged to be rigidly connected thereto by means of a sleeve 18" (see Figure 16),
which is splined to the shaft so as to slide freely thereon, and is provided with a
tongue which enters a corresponding recess in the hub of the arm 9. The clutch
thus formed is provided with an operating handle 19, which extends outward to the
side of the machine, and is provided with a fork which rests in a groove in the
sleeve 18ª.
The folding mechanism thus organised, is provided with four sets of sheet-con-
ducting tapes 2, 3, 4", 5", which are arranged as follows:-The tapes 2° pass
between the delivery pulleys 20", 21", which are mounted respectively on the
shafts 37, 38 before referred to, and are located in close proximity to the impres-
sion cylinder, as is usual, and thence forward beneath the folding rolls 40. The
tapes of this series which are upon one side of the rolls 40, pass upward around a
series of stretching pulleys 22", which are mounted on arms extending from a trans-
verse shaft 34", the outer end of which shaft is supported in the side frame, and
the inner end by a longitudinal rod 33, which extends at the side of one of the
rolls 40, from to the other of the bars a b', as best shewn in Figure 11. The tapes
of the series 2 upon the other side of the rolls 40, pass forward above a roll 32ª,
and downward partly around said roll, and upward around a roll 31, and a series
of stretching pulleys 30. From the pulleys 22-30%, all of the tapes 2 except
the marginal ones, return directly around the pulleys 20. The marginal tapes of
this series, however, pass between the outside pulleys of the series 20" and a rod 46°,
and thence around the ends of the impression cylinder, returning above the outside
pulleys of the series 21°. The tapes 3* pass around the pulleys 21ª, thence forward
with the tapes 2, around the roll 32ª, returning directly from the roll 32 to the
pulleys 21° The tapes 4 pass around a series of pulleys 23 mounted upon a
shaft 24", which is rigidly secured in the ends of the arms 25", extending from a
transverse shaft 26", the outer end of which is mounted in the side frame, while its
inner end is journalled in a bearing mounted upon the rod 33°, thence downward in
an inclined direction above the roll 32", and thence upward around the roll 31ª,
returning around stretching pulleys 30°. The tapes 5º pass under one, thence
between, and thence above the other of the folding rolls 40, and outward to the side
of the machine, and thence around pulleys 28 and inward, returning around
stretching pulleys 29".
In addition to the tapes already referred to, there is provided the usual tape 6º,
which passes around the middle of the impression cylinder at the point where the
blank space usually occurs between the printed pages of the sheet; thence above

page_text: the central one of the pulleys 21", and around the corresponding one of the
pulleys 20º.
Located just below the plane of the tapes 5, as they pass outward from the
rolls 40 to the side of the machine, are a series of stationary guides 47", which are
arranged to co-operate with the tapes 5*, to convey sheets outward to the side of the
machine, after they have been folded between the rolls 40.
Located just below the plane of the tapes 5 and guides 47", is a transverse
roll 48, which extends from the side of the machine inward to near the forward
ends of the folding rolls 40, its outer end being journalled in the side frame, and its
inner end in a bearing supported upon the rod 33". This roll is located in such
position as to be directly beneath, and co-operate with, the pulleys 24°, when the
latter are vibrated downward, as will hereinafter be explained.
The space between the pulleys 22" and the roll 32" is bridged by stationary
guides 8, which are arranged to co-operate with the tapes 3, and the space between
the roll 48 and the roll 32" is bridged by similar guides 7", which are arranged to
co-operate with the tapes 4". These guides are supported upon a rod 49", the outer end
of which is supported in the side frame, while its inner end is supported by the
rod 33".
The folding mechanism is also provided with two series of adjustable stops 50", 51",
the former of which are arranged near the ends of the folding rolls 40, and so as to
be interposed in front of the sheets, in passing forward between the tapes 2", 3".
These stops are mounted upon a rock shaft 52", by which means they can be moved
out of the path of the sheets, when desired.
The stops 51 are located near the side of the machine and are interposed in the
path of the sheets as they pass outward from the folding rolls between the tapes 5"
and guides 47".
One of the arms 25 which support the shaft on which the pulleys 24" are mounted,
is connected to one end of a vertical rod 53", the lower end of which is connected to
one arm of a bell-crank lever 54", the opposite arm of which lever is connected to a
rod 55, the end of which is bifurcated, and straddles the main shaft 99, and is
provided with a bowl which is acted upon by a cam 56" upon the main shaft,
in such manner as to periodically rock the shaft 26", and lower the pulleys 24" into
nipping contact with the roll 48°. The rod 53 is provided with a spring 57, which
is interposed between a collar on the rod, and a bracket 58 extending from the
frame of the machine, and operates to hold the pulleys 24" in their raised position,
except when they are moved downward by a cam 56". The rod 53" is also provided
with a moveable collar 59", having a set screw by which it can be fastened to the
rod in any position, the purpose of which will be presently explained.
The operation of the mechanism thus organized, is as follows:-If it is desired
to deliver the sheets in an unfolded condition, as, for example, when they are passed
through the press for the first time, and are only printed on one side, the shaft 52°,
carrying the stops 50", will be rocked so as to take the stops out of the path of
The sleeve 18
the sheets, as they pass forward between the tapes 2", 3ª.
will
be shifted so as to release the arm 9" from the shaft 41%, and thus render the
folding blade 42 idle, and the pulleys 23 will preferably be rocked downward
into nipping contact with the roll 48", and secured in that position by moving the
collar 59 up against the underside of the brackets 58°, and securing it in that position.
The sheets then, as they are taken by the tapes 2", 3", will be carried forward
between said tapes, and beneath the guides 8" and tapes 4", and will emerge from
between the rolls 32, 31, in front of the fly, and be piled in an unfolded condition.
If, on the other hand, it is desired to fold the sheets, the stops 50 will be
interposed in the path of the sheets; the sleeve 18" will be shifted so as to lock the
arm 9 to the shaft 41, and put the folding blade 42 into operation, and the
collar 59 will be moved away from the brackets 58, so as to allow the pulleys 23
Each sheet will then
to be raised by the spring 57, and depressed by the cam 56".
pass forward between the tapes 2, 3, until it arrives at the stops 50º.
will be so timed that, as each sheet is arrested by the stops, the folding blade 42
The parts

page_text: will be vibrated quickly upward, so as to fold the sheet into the bite of the folding
rolls 40. The sheet thus folded, as it emerges from the rolls 40, will be carried
outward above the guides 47" by the tapes 5, until it arrives at the stops 51".
It will be observed that the stops 50 are so located that the forward end of each
sheet, or what, after folding, becomes one of its sides, will, as the sheet is carried
outward between the tapes 5" and guides 47", project above the roll 48ª, and beneath.
the pulleys 23. The parts will be so timed that, as soon as each sheet arrives at
the stops 51°, as just explained, the cam 56" will rock the arms 25ª downward, and
carry the the pulleys 23" into biting contact with the roll 48". The side of the
sheet, or what now becomes its leading end, and which, as just explained, projects
between the pulleys 23" and roll 48", will thus be taken by the roll 48" and the
tapes 4", and carried forward between the tapes 4" and guides 7", and will thence
pass between the rolls 31, 32, and emerge in front of the fly, and be piled in a once
folded condition.
In Figures 17 to 21, there is shewn a machine of a slightly modified form, which
is capacitated by slight adjustment to fold the sheets with the printed side either
upon the inside or outside, and this construction will now be described.
In this construction, the folding rolls 40 and folding blade 42 are mounted in
the same manner, and actuated by substantially the same mechanism as in
the construction last described, except that the blade is placed above the rolls, so
as to fold the sheets downward.
The machine is provided with five sets or series of co-operating sheet-conveying
tapes 2, 3, 4, 5, 6, which are arranged as follows:-The series 2 pass between
the usual delivery pulleys or rolls 38, 39, located at the inner ends or the folding
rolls, and in close proximity to the impression cylinder, thence forward above the
folding rolls 40, and beneath a roll 19, and over a roll 20%, located above, and at
the outer end of the folding rolls; thence downward in an inclined direction past a
roll 21, and upward around a roll 14", and thence rearward around tightening
pulleys 26. From the pulleys 26, all of the tapes except the two marginal ones
return directly around the pulleys 38. The two marginal tapes of the series, how-
ever, pass beneath a roll 16b, and thence around the impression cylinder near its ends,
returning over the end pulleys of the series 39. The series of tapes 3" pass around
the pulleys 39, thence forward with the tapes 2", beneath the roll 19", and over the
roll 20, and thence rearward above tightening pulleys 22" to the pulleys 39. The
tapes of the series 4° upon one side of the rolls 40, pass around a roll 15 located
just beneath and in advance of the roll 20", thence beneath the roll 20 and rearward
with the tapes 3 to the pulleys 22b; thence around the pulleys 22, and forward
beneath a pair of rolls 23, 24° to the roll 15. The rolls 23", 24" extend inward
only to the ends of the folding rolls 40, and are journaled at their inner ends in a
bracket extending from the bar ". The tapes of the series 4" upon the other side
of the rolls 40, return from the pulleys 22 directly to the roll 15. The series of
tapes 5t
pass above one of the folding rolls 40, thence between the rolls, and
beneath the other of the rolls, and outward, beneath, but out of contact with, the
tapes 4 to the side of the machine, from which point they return around pulleys 25"
and stretching pulleys 30. The series (pass around pulleys 31b, located beneath
the roll 23, and mounted in the ends of swinging arms 32b, which extend from the
bar thence forward with the tapes 4 beneath the rolls 23, 24, 15, and with
the tapes 2 around the roll 21%, returning thence directly to the pulleys 31". In
addition to the tapes already specified, the cylinder D is provided with a single
tape 7, which passes around the middle of the cylinder, and above the central one
of the pulleys 39, and returns around the pulleys 38". Directly above the folding
rolls, there are located two pairs of stationary guides c", d", the former of which
serve to support the middle of the sheets as they are carried forward between the
tapes 2, 3, and the latter to support the middle of the sheets as they are carried
in the opposite direction between the tapes 3, 4 There are also provided a
series of stationary guides 33, which are located directly above, and co-operate
with the tapes 5", as will hereinafter appear. The space between the rolls 20, 21",
;

page_text: is bridged by a series of switches 34, which can be shifted so as to direct the
sheets from between the tapes 2, 3b, into the bite of the tapes 3, 4", or so as to
direct the sheets forward to the roll 17. In this latter case, these switches also
serve as guides which co-operate with the tapes 2". The shaft 47 upon which
the switches 34" are mounted, is provided with an arm 48, having a locking bolt by
which the switches can be shifted to, and secured in either of the positions just
stated. The arms 32, in which the pulleys 31 are mounted, are rigidly secured
to a rock shaft 37, the inner end of which is mounted in a bracket extending from
the bar while its outer end is journaled in the side frame. To one of the
arms 32" there is pivoted a rod 50", the opposite end of which is pivoted to one
arm of a bell-crank lever 51, the other arm of which is pivoted to a rod 52",
having a bowl or stud which is acted upon by a cam 53, upon the driving shaft 99,
in such manner as to periodically raise the arm 32, and bring the pulleys 31" into
nipping contact with the roll 23. The rod 50 is provided with a spring 49",
which acts against a bracket 54" upon the frame-work, and the tendency of which
is to move the rod 50" and pulleys 31" downward, and hold the bowl on the rod 52"
in contact with the cam 53%. The rod 50 is also provided with an adjustable
collar 46", arranged above the bracket 54", the purpose of which will appear when
the operation of the mechanism is explained. The roll 21 is geared to one of the
folding rolls 40, and the rolls 21, 15, 20, are geared together, as shewn. The
folding mechanism thus organized is provided with three sets of stops 55", 56",
and 57", which are arranged as follows:-The stops 55" are located above the
outer ends of the folding rolls 40, and are arranged to be interposed in the path
of the sheets, as they pass forward between the tapes 2, 3. These stops are
mounted upon a rock shaft 58b, having a handle 59", by which it can be rocked so
as to carry the stops 55 into and out of operative position. The handle 59b is
provided with a locking bolt, by which the stops can be secured in either position.
The stops 56 are located near the inner ends of the folding rolls 40, and are inter-
posed in the path of the sheets, as they pass inward between. the tapes 3, 4°. The
stops 57 are located above the pulleys 25, and are interposed in the path of the
sheets, as they pass outward between the tapes 5" and guides 33". All of these
stops will be made adjustable, so that their positions may be varied.
The operation of the combined press and folding mechanism thus organized is
as follows-If it is desired to deliver the sheets in an unfolded condition, the
sleeve 18 will be shifted so as to disconnect the arm 9" from the shaft 41", and
allow the folding blade 42 to remain idle, and in its raised position. The shaft 58
will be rocked, and secured in position to remove the stops 55° from the path of
the sheets, and the switches 34 will be set in position to direct the sheets from the
roll 20° to the roll 21b. The pulleys 31 may also, if desired, be secured in
their raised position, which can readily be done by raising the pulleys and moving
the collar 46 downward, and setting it on the rod 50" directly above the bracket 54".
The sheets will then, as they are directed off the cylinder, be carried forward
by the tapes 2b, 3b, above the guides c, until they arrive at the roll 20, after
which they will pass downward between the tapes 2" and switches 34, and will
emerge from between the rolls 14, 21, in front of the fly, and be piled in a
flat or unfolded condition. If, on the other hand, it is desired to deliver the sheets
in a folded condition, the sleeve 18 will be shifted so as to connect the arm 9° to
the shaft 41, and put the folding blade 42 into operation; the switches 34" will be
set in the position shown in the drawings, the collar 46 will be raised so as to
allow the pulleys 31° to be vibrated; and, if it is desired that the side of the sheet
last printed shall be upon the outside of the sheet after it is folded, the stops 55
will be lowered to the position shown. The cam 45" will also, if necessary, be
shifted so as to properly time the movements of the folding blade 42". The sheets
will then, as they are directed off the impression cylinder, be carried forward
above the guides c" by the tapes 2' 3b, until they arrive at the stops 55°. The
parts will be so timed that as the leading end of each sheet arrives at the stops 55',
the blade 42 will be moved quickly downward, so as to double the sheet between

page_text: the guides c", and fold it into the bite of the rolls 40. As the folded sheets emerge
from between the rolls 40, they will be carried outward toward the side of the
machine, between the tapes 5 and guides 33", until they arrive at the stops 57.
The stops 55 are so positioned that the rear ends of the sheets will extend nearly
or quite to the forward ends of the folding rolls 40, from which it results that, as
the sheets are carried outward by the tapes 5, their rear ends, or what is then
one of their sides, will project beyond the marginal tape of the series 5, and
above the pulleys 31 and tapes 6º. The parts will be so timed that, as each
of the folded sheets arrives at the stops 57, the arms 32" will be moved
upward quickly, so as to carry the pulleys 21" into nipping contact with
the roll 23b. This will cause the side of the sheet, or what then again becomes its
leading end, which projects above the pulleys 31, to be taken by the tapes 4" 6,
and carried forward between rolls 15, 21, where it will be directed by the lower
parts of the switches 34 between the tapes 2b, 6, and projected downward from
between the rolls 14, 21, in front of the fly, by which it will be laid upon the piling
table in a folded condition, with the side of the sheet last printed upon the outside
of the folded sheet. If it is desired that the sheet should be so folded that the side
of the sheet last printed will be upon the inside of the folded sheet, the adjustments
will be the same, except that the stops 55 will be raised, and the cam 45 shifted,
if necessary, so as to properly time the movements of the folding blade 42. The
sheets will then be carried forward to the roll 20%, and will be directed inward
between the rolls 15%, 20%, and pass into the control of the tapes 3", 4", by which
they will be carried inward until they arrive at the stops 56. As each sheet arrives
at the stops 56, it will be folded into the bite of the rolls 40, after which the opera-
tion will be the same as already described. It will be observed that in this case,
however, the sheets are so presented to the folding rolls, that when they are folded,
the side of the sheet last printed is upon the inside of the folded sheet.
If, in any case, it should not be desired to capacitate the machine to deliver the
sheets in an unfolded condition, as, for example, when the machine is to be used
exclusively for printing "patent insides," or for printing the second side of the sheets,
the switches 34 may be made stationary, instead of movable, or the switches may
be omitted, and the tapes 2 carried inward around the pulleys 22", and then outward
above the roll 21, so as to take the place of the tapes 4". Or if, in any case, it
should not be desired to capacitate the machine to fold the sheets so that the side
last printed will be upon the outside of the folded sheet, the stops 55° may be
omitted.
