[Communicated from abroad by ROBERT HOE, of 504, Grand Street, in the City
of New York, United States of America, Printing Press Manufacturer:]
Improvements in Printing and Folding Mechanisms.
HENRY EDWARD NEWTON of The Office for Patents, 6 Bream's Buildings,
Chancery Lane in the County of London, Patent Agent, do hereby declare the
nature of this invention and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement :-
This invention relates to a folding mechanism which is especially designed and
adapted to be combined with a printing mechanism of the kind known as a cylinder
press, although the folding mechanism may be used alone, or in combination with
presses of other classes, and in itself forms a part of the invention.
It is the object of the invention to produce a combined press and folding
mechanism in which the parts shall be so constructed, and organized, that the
combined press and folder will occupy no more space than that occupied by
the press alone, and which shall be capacitated, by slight adjustments, to deliver the
sheets either in an unfolded condition, or folded to different dimensions, as, for
It is also the object of the invention,
example, with one, two, three, or four folds.
to provide an uniform folding mechanism of general application, and especially to
provide a folding mechanism of the character above described which shall be so
constructed and organised, that can be applied to presses already in existence,
without the necessity of making material alterations in their organization. As a
full understanding of the invention can best be given by a detailed description of
the construction and operation of the mechanism embodying the same, all further
preliminary description will be omitted, and a full description given, reference being
had to the accompanying drawings, in which the principal figures show a combined
press and folding mechanism constructed according to the present invention, which
is capacitated to print and deliver the sheets either in an unfolded condition, or
with one, two, three, or four folds, as may be preferred.

Figs. 31 to 34 illustrate details which will be hereinafter referred to, Fig. 32
being upon an enlarged scale; and
Fig. 35 is a diagrammatic view illustrating certain modifications which will be
explained.
Referring to Figs. 1 and 2, 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, G the fly shaft, and H the piling table 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 cominon 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
shaft G and the piling table H are also located in the usual positions. From this
it will be seen that the printing mechanism is of the ordinary and well known
form.
The folding mechanism which is combined with this printing mechanism, is in
part located beneath the feed board, and in the path which the sheets take in
machines of this class, in passing from the impression cylinder to the fly, and
iu part on the fly shaft, and beneath the piling table.
The part of the folding mechanism which is located beneath the feed board, is
capacitated to impart two folds to the sheets, and the part which is located on the
fly shaft and beneath the piling table, is capacitated to impart two additional folds.
When it is desired to deliver the sheets in an unfolded condition, the whole folding
mechanism is rendered inoperative, and the sheets, after being printed, pass to the
fly, and are laid upon the piling table in the usual manner. When the sheets are
to be delivered with one fold, the folding mechanism under the feed board is
adjusted so that the sheets receive one fold before they reach the fly. When the
sheets are to be delivered with two folds, the mechanism beneath the feed board is
put into full operation, so that they receive two folds before they reach the fly.
When the sheets are to receive three folds, the fly is removed, and the sheets, after
being folded twice by the mechanism beneath the feed board, receive one additional
fold from the folding mechanism upon the fly shaft, and beneath the piling table.
When four folds are required, the whole folding mechanism is put into operation.
That part of the folding mechanism which is located beneath the feed board is
the same, except as to one or two minor particulars, which will be hereinafter
referred to, as that shown in a Patent granted to H. E. Newton. (the present

page_text: applicant) dated 22 March 1892, No. 5640; a general description and lustration
of this part of the mechanism, without going into all of its details, will therefore be
sufficient in the present case.
This part of the folding mechanism consists primarily of two pairs of folding
rolls 40-41, 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, about mid way of its length, and the rolls 41
are arranged parallel with the impression cylinder, and below, and at right angles
to the rolls 40, about midway of their length, and extend from the rolls 40 outward
to one side of the machine. The folding rolls 40 are geared together in the usual
mauner, and receive motion from a gear upon the shaft 39 of the usual delivery
pulleys 54, which shaft is geared to the impression cylinder. The folding rolls 41
are also driven from the shaft 39 by means of a belt 38, which passes around a
pulley upon said shaft; thence between pulleys upon the shafts of the rolls, and
around a pulley upon the shaft of the usual tape pulleys, or roll, 44, returning
beneath a stretching pulley 37. The folding blade 42 is connected to arms
extending from a pair of rock shafts 45, one of which is provided with an arm
which is acted on by a spring in such manner as to rock the shafts and hold the
blade 42 in its raised position. The other of the shafts is provided with an arm to
which is pivoted a vertical rod 47, the lower end of which is acted on by a cam 48
upon the main shaft 99, 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 upon the shaft 45 to
which the rod 47 is pivoted, is connected to the shaft by a clutch mechanism, so
that, when desired, the arm can be disconnected from the shaft, thus throwing the
blade 42 out of operation, and permitting it to remain in its raised position. The
folding blade 43 is mounted upon arms 32 extending from a transverse rock
shaft 49, which is provided with an arm 50, to which is pivoted a rod 51, the end
of which is acted on by a cam 52 on the shaft 99, 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 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 shalt 49,
and depress the blade 43, when, by the movement of the cam 52, it is permitted to
do so,
The arm 50 is also connected to the shaft 49 by means of a clutch
mechanism, so that when desired, the arm can be disconnected from the shaft. A
suitable means is provided, as, for example, a hook 98, by which the blade 43 can
be retained in its raised position, when it is not in use.
The folding mechanism thus organized is provided with six sets of sheet-con-
veying tapes, 2, 3, 4, 5, 6, and 26, which operate to take the sheets from the
impression cylinder, and convey them either directly to the fly, in an unfolded
condition, or 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 fly, or the
subsequent folding mechanism, after being twice folded. These tapes are arranged
as follows:-The tapes 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 tapes 2 pass between the delivery pulleys 54 and the
usual series of cooperating pulleys mounted loosely upon a shaft 56 located above
the shaft of the delivery pulleys, thence forward above the folding rolls 40, and
over the 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 58. From the
pulleys 58, all of the tapes except the two marginal ones return directly around
the pulleys upon the shaft 56. The two marginal tapes pass beneath a rod 59,
and thence around the impression cylinder, near its ends, returning over the
pulleys 54. The tapes 3 pass around the 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

page_text: those upon the other side of the rolls 40 return over a roll 30, which extends
inward from the side frame to the rolls 40. The tapes 4 pass over one of the
folding rolls 40, 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
stretching pulleys 61. The tapes 5 pass around a series of pulleys 20, mounted
loosely on a shaft 21 (see Fig. 14), which is located directly beneath the roll 30,
and is rigidly supported in the ends of a pair of arms 22 extending from a
transverse shaft 8, and return around a roll 23 located beneath the roll 44.
The tapes 6 pass around the outer one of the folding rolls 41, and thence down-
ward and forward at an incline, returning around pulleys 64. In the organization
shown and described in my prior application hereinbefore referred to, the tapes 6
are provided with a series of co-operating stationary guides, which lie beneath
the tapes and extend from the rolls 41 to the pulleys 64. In the present case,
however, these guides are omitted, and, in their stead. is provided a series of
tapes 26, which pass around the inner one of the folding rolls 41, and thence
between the rolls, and forward and downward with the tapes 6, returning around
pulleys or a roll 62 located beneath, or substantially beneath, the pulleys 64.
addition to the various tapes already referred to, there may be provided a 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, thence
above the central one of the pulleys 54, and around the corresponding one of the
pulleys upon the shaft 56.
In
Located above the tapes 4, are a series of stationary guides 28, which extend
from the folding rolls 40 outward to the side of the machine. These guides
co-operate with the tapes 4 to convey the sheets from the rolls 40 outward above
the rolls 41.
Located above the tapes 5, are a series of stationary guides 27 (see Fig. 14),
which extend from the roll 30 forward, and turn downward over the roll 23.
These guides cooperate with the tapes 5, to convey the sheets outward above
the roll 23, as will be hereinafter explained. These guides are provided, at
their outer ends, with upward extensions 24, which bridge the space between the
rolls 44, 23.
This part of 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 desired. 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 outer ends of the guides 28.
The hub of one of the arins 22, in which the shaft 21 is mounted, is provided
with an arm 73, the end of which is provided with a swivelled eye-bolt, through
which extends the end of a rod 74, baving a head at its end, between which and
the eye-bolt is arranged a spring 88. The opposite end of the rod 74 is provided
with a yoke, which is arranged to embrace a stud on the end of an arm 75,
extending from the hub of the arm 50 which operates the folding blade 43.
This part of the folding mechanism may be provided with a slitter, 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
mounted upon a shaft which is supported in arms 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 inoperative, when desired. The shaft upon
which the slitter is mounted is provided with a gear which, when the shaft is
lowered so as to carry the slitter into operative position, engages with a gear 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 curvative of the folding
rolls 40.

page_text: The fly F (see Figs. 13 and 14) is of substantially the usual construction,
except that those of its fingers which are in front of the folding rolls 41 and
pulleys 62, 64, are cut away so as to provide an opening in front of the
pulleys 62, 64. The portions of the fly fingers which are above the opening f, are
supported upon a cross bar 82, which is secured to some of the uncut fingers. The
fly 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, upon the
main shaft.
I
The fingers composing the fly frame, instead of being attached directly to the
fly shaft G,
are secured to a cross piece g (see Figs. 13 and 14), which in turn is
detachably secured to the shaft by means of bolts 104, which enter slots 105
formed in the usual flange of the shaft. By this means the fly F can be readily
and quickly removed from the shaft, and replaced thereon, when desired. The
purpose of this will be made clear when the operation of the mechanism is explained.
For a more detailed illustration any description of the folding mechanism which
has thus been described in a general way, reference is made to my prior application
before referred to.
The second part of the folding mechanism, which is located on the fly shaft, and
beneath the piling table, is constructed and arranged as follows:-The fly shaft G
carries a folding blade 150, which, when. in its normal position, extends upward
from the shaft, inside the fly fingers, and terminates somewhat below the pulleys 62.
Located just inside the fly fingers, and in front of the blade 150, are two series of
guides 148, 149, which extend from in front of the pulleys 62, 64, downward to a
point somewhat above the fly shaft G, and between which the sheets may be
directed as they emerge from between the pulleys 62, 64, so as to pass downward
in front of the blade 150, as will be hereinafter more fully explained. These
guides are supported at their lower ends upon rods 147, which extend inward from
the brackets which support the fly shaft, and terminate near the blade 150, so as
to allow the blade to pass, between their ends. The guides 148 afford bearings at
their upper ends for a pair of rods 146, which carry a series of switches 119, which
are so arranged that they will operate to direct the sheets downward between the
guides 148, 149, or forward through the opening in the fly. The rods 146 are
provided with suitable means, as the arms 145, by which they can be rocked to
move the switches to either position, as may be required. The rods 146 are
provided with arms 118 (see Figures 1, 2, and 11), which support a rod 117, upon
which are mounted a number of guides 25, which co-operate with the switches 119,
to direct the sheets through the opening F, when the switches are shifted to
the position shewn in Figure 14. The two guides 148 which are nearest to the
blade 150, are comparatively close to each other, so that as the blade is rocked
forward, as will be hereinafter explained, they operate as folding bars or guides to
fold the sheet which has been directed downward between the guides 148, 149,
across the edge of the blade. The rods 147, in addition to the guides 148, 149,
may also support a pair of side guides 144, which will act upon the edges of the
sheets, so as to prevent them from being moved laterally out of proper position in
front of the blade 150.
K," and.
The piling table "H" is supported upon a rectangular casing or box"
is made so that it can be either wholly removed from the top of the casing, or is
made in sections so that portions of it can be raised and folded back to expose the
interior of the casing.
When the sheets are to be delivered in an unfolded condition, or with one or two
folds, the piling table "H" is placed upon the top of the casing "K," or, if it is
nade in sections, the sections are turned down, so as to present a plain surface, as
shewn in Figure 15, upon which the sheets are laid by the fly, in the usual
manner. When the sheets are to be delivered with three, or with four folds, the
table "H" is removed, or the sections are folded back, as best shewn in Figures 3
and 5, so as to expose the interior of the casing.

page_text: Mounted in the casing "K," beneath the table "H," is a shaft 143, which is
arranged at right angles to the fly shaft, and in line with the blade 150, and is
provided with a folding blade 142, similar to the blade 150. The shaft 143
-extends beneath the fly shaft, and to a point beneath the main shaft 99, and is
made in two parts, which are connected by a coupling consisting of a collar 141
and suitable set screws. The shaft 143 is provided with a spring 137 (sec
Figures 17 and 18), the tendency of which is to hold the shaft in such position,
that the blade 142 will stand in a vertical position, as shown in Figures 9, 10,
and 11. The shaft 143 is provided with a stud 139 (see Figures 16, 17, and 18),
which is acted on by a cam 138 on the main shaft 99, in such manner as to
periodically rock the shaft 143 against the tension of the spring 137, and vibrate
the blade 142 from the vertical position shown in Figures 9, 10, and 11, down to
the horizontal position shown in Figures 3, 4, 5, 6, 7, and 12.
In addition to the blade 142, the shaft 143 is provided with six arms c, d, e,
which are mounted loosely upon the shaft, so as to assume either a vertical or a
horizontal position. The arms e, which are the middle ones of the series, are
provided with two upwardly or outwardly extending bars or rods 136, which are
comparatively close to each other, and in such position that the blade 142 will pass
between them, as it is vibrated from its vertical to its horizontal position. The
arms c are also provided with two rods 135, which are arranged in, or substantially
in, line with the rods 136. The rods 135, 136 are so positioned, that when the
arms care in their vertical position, and the folding blade 142 is in its normal
position, it will be somewhat in the rear of the rods. The arms d are provided
with upwardly or outwardly extending rods 134, similar to the rods 135, but so
located, that when the arms are in their vertical position, the folding blade 150
will, when it is vibrated to its horizontal position, pass between them and the
rods 135 136. The arms e are provided with a pair of rods 133, which are
arranged in line with the rods 135-136, and with a second pair of similar
..rods 132, which are arranged in line with the rods 134. The outer one of the
arms e is also provided witli a slotted guide 131, which serves as an edge guide for
the sheet, and also as a guide for the end of the folding blade 150, when it is
vibrated from its vertical to its horizontal position.
The rods 132, 133, 134, 135 and 136, serve as side guides or supports to receive the
sheets from the blade 150, and to support them in position to be acted on by the
blade 142, and the rods 136 also serve as folding bars or guides to fold the sheets
across the edge of the blade 142.
The arins c, d, e, carrying the rods and guide just described, are held in their
vertical position by means of sliding rods 130, which are supported in brackets 129,
and pass through openings in the arms, as shewn.
Located at right angles to the shaft 143, and directly in front of the blade 142,
is a shaft 128, which is provided with a pair of upwardly projecting jaws 127, one
of which is rigidly fixed to the shaft, while the other is pivoted to the shaft, and is
.normally held pressed against the rigid jaw by means of a pivoted spring-pressed
rod 126. The shaft 143 is provided with a cam 125 (see Figures 5, 6, 10, and 12),
which acts upon a bifurcated arm 124 extending from the shaft 128, in such
manner, that, as the shaft 143 is rocked to vibrate the blade 142 from its vertical
to its horizontal position, the shaft 128 will be rocked, so as to close the jaws 127,
while, as the shaft 143 is rocked in the reverse direction, to return the blade 142 to
its vertical position, the shaft 128 will be rocked in the reverse direction, so as to
open the jaws 127. The bottom of the casing "K" is provided with two channels l,
in which are located a pair of bars 123, which bend upward at their inner ends, and
pass through openings in the jaws 127, and are arranged to be moved freely
longitudinally in the channels 7. These bars are connected by pivoted links 122
with the rigid jaw 127, so that each time the shaft 128 is rocked to close and open
the jaws 127, the bars 123 are reciprocated in the channels 1. The bars 123 are
provided, just in the rear of the jaws 127, with a pair of pivoted arms 121, which
are arranged to be turned up to a vertical, or down to a horizontal position. The

page_text: pivoted ends of the arms 121 are provided with square shoulders, as shown, which
are acted on by springs 120, in such manner as to retain the arms in either their
vertical or their horizontal position. Each of the bars 123 is also provided with a
pair of pivoted dogs 106, which are arranged to swing freely outward, but are
limited in their inward movement by stops 107 formed on the bars. These dogs.
extend below the lower edges of the bars, and their lower ends are arranged to act
upon inclines 108 formed in the bottoms of the channels i. The inclines 108 are so
arranged that as the bars 123 are moved outward by the rocking of the shaft 128,.
to open the jaws 127, the dogs 106 will ride upon the inclines, and thus raise the upper
edges of the bars above the surface of bottom of the casing, until the bars arrive
at the limit of their outward movement, as shown in Figure 8, when the dogs 106
will drop off the ends of the inclines, and allow the bars to fall back into the-
channels. As the shaft 128 is rocked in the reverse direction, and the bars make
their return movement, the dogs 106 will turn upon their pivots, and pass idly over-
the inclines without raising the bars.
The especial purpose of the various features of construction which have been
described, will more fully appear when the operation of the combined press and:
folding mechanism is described.
The combined press and folding mechanism is herein shown as provided with a
pasting mechanism by which, when desired, a line of paste can be applied to one
half of the sheet, in such position that when the sheet is folded, the two halves will
be united to each other along the line between the printed pages. This pasting:
mechanism consists of a cylinder having a contracted nozzle or discharge opening,.
which is arranged in position to discharge a fine line of paste upon the sheet, as
it passes beneath it, in being folded, between the folding rolls 40. This cylinder is-
arranged in a paste fountain or vat 100, and is provided with a reciprocating piston
or plunger which operates, upon its suction stroke, to draw a supply of paste into-
the cylinder, and upon its force stroke to eject the paste through the contracted
discharge opening of the cylinder, on to the moving sheet.
This piston is operated by arms extending from a rock shaft 96, which is provided.
with an arm 109, to which is pivotally connected a rod 101, which is acted on by
a cam 102 mounted on the main shaft 99. These parts are so arranged, that the
piston will be moved downward by the cam at the proper time to discharge the-
paste from the cylinder, while the sheet is moving beneath the nozzle in the proper
position to receive it. The movement of the shaft 96 in the opposition direction,.
is effected by means of a spring 103, suitably arranged for that purpose.
The operation of the combined press and folding mechanism thus constructed.
and organised, is as follows:-The operation of the mechanism, when adjusted to
deliver the printed sheets with four folds, will be first described.
When it is desired to deliver the sheets with this number of folds, the piling
table H will be removed from the casing "K," or, if the table is made in sections,
the sections will be folded back as shewn in Figure 3, so as to expose the interior
of the casing; the arms c, d, e will be turned up to their vertical position, and
secured in that position by the rods 130, and the arms 121 will be turned up to.
their vertical position; the fly F will be removed from the shaft G; the
switches 119 and guides 25 will be turned to the position shown in Figures 1
and 11, so as to direct the sheets from the pulleys 62, 64, downward between the
guides 148-149; the stops 69 will be lowered so as to be interposed in the path.
of the sheets as they pass forward between the tapes 2-3; the clutch upon the.
shaft 45 will be adjusted so as to throw the folding blade 42 into operation; the
clutch upon the shaft 49 will be adjusted so as to throw the folding blade 43 into.
operation; and the rod 74 will be disconnected from the arm 75, and hooked on to
a stationary stud 87, provided for that purpose, so as to cause the pulleys 20 to.
remain idle (all as shown in Figures 1 to 8). With the mechanism thus adjusted,.
the sheets fed froin the feed table E will be taken by the grippers upon the
impression cylinder and presented to the form C, and printed in the usual manner,

page_text: As the
after which they will be carried off the cylinder by the tapes 2, and the centre tape
or tapes hereinbefore referred to, and pass into the control of the tapes 2-3, by
which they will be carried outward above the folding rolls 40, until their leading
ends arrive at the stops 69. As the leading end of each sheet arrives at the
stops 69, the folding blade 42 will be operated so as to fold the sheet into the bite
of the rolls 40, and after being thus folded, the sheet will be carried outward by
the tapes 4 above the folding rolls 41, until it is arrested by the stops 70.
slicet is thus arrested, the folding blade 43 will be operated to fold the sheet into
the bite of the rolls 41, thus imparting the second fold, after which the sheet will
be carried to the pulleys 62-64 by the tapes 6-26. The operation thus far
described is the same as that of the mechanism described in the Patent herein-
before referred to. As the leading end of each sheet arrives at the pulleys 62-64,
it will be directed downward by the switches 119, and pass downward between the
guides 148-149 in front of the folding blade 150, as shown by dotted lines in
Figure 4. As the sheet I arrives in the proper position in front of the blade, the
shaft G will be rocked, so as to vibrate the blade 150 downward from its vertical to
its horizontal position, and, as the blade is thus vibrated, it will strike the sheet at
its centre, and carry it between the central ones of the guides 148, and these
guides co-operating with the blade as folding bars, will double the sheet across
the edge of the blade, thereby giving it a third fold. As the blade continues
its forward and downward movement, it will carry the folded sheet between the
vertical rods 132-134, and 133-135-136, until its folded edge is brought to
rest upon the upper ends of the arms c, d, e, as shown by dotted lines in Figure 4.
When the sheet is in this position, it will be supported by the rods 132-133-134
and 135, and will lie between the rods 136 and the folding blade 142 As the
shaft G is vibrated in the reverse direction, the blade 150 will be carried out from
between the plies of the folded sheet, and the sheet will be left standing in a vertical
position between the rods 136 and the blade 142. As the blade i50 is thus vibrated
back to its original position, and after it has been withdrawn from between the plies
of the folded sheet, the cam 138 will rock the shaft 143, so as to vibrate the
blade 142 from the vertical position shown by dotted lines in Figure 5, down to
the horizontal position shown by full lines in said figure. As the blade 142 is thus
vibrated, it will strike the sheet upon its central line, and carry it between the
rods 136, and these rods, co-operating with the blade as folding bars, will double
the sheet across the edge of the blade, thereby imparting to it a fourth fold, and as
the blade 142 is thus vibrated, the cam 125 will, as already explained, rock the
shaft 128, so as to close the jaws 127, and draw the bars 123 inward, so that as the
blade arrives at its horizontal position, it will force the newly folded edge of
the sheet into the bite of the closed jaws, as shewn in Fig. 7, and by dotted lines
in Fig. 5, the pivotted member of the jaws yielding sufficiently against its spring
to permit this. As soon as the folded edge of the sheet has been thus inserted
into the bite of the jaws 127, the shaft 143 will be rocked in the reverse
direction, so as to carry the blade 142 back to its vertical position, and as
the blade is thus carried back to its vertical position, and after it has been
withdrawn from between the plies of the folded sheet, the cam will, as already
explained, rock the shaft 128, so as to open the jaws 127, and move the bars 123,
and the arms 121 carried by the bars, outward, as shewn in Fig. 8. When the
sheet is left standing in the bite of the jaws 127, as just explained, it will be sup-
ported, on one side, by the arms 121, but will be unsupported upon the other side,
so that the sheet will have a tendency to fall over onto the bars 123. From this
it will result that as soon as the jaws 127 are opened, the sheet will fall over into
a flat position upon the bars. As the bars are moved outward, they will, by the
action of the dogs 106 upon the incline 108, be raised, as already explained, and as
shewn in Fig. 8, so that they will lift the sheet, and carry it outward a short
distance. This operation will be repeated as each sheet is printed and carried off
the impression cylinder. As the jaws 127 are closed, preparatory to receiving each

page_text: sheet, the bars 123 will be drawn inward, but the dogs 106 having passed beyond
the ends of the inclines 108, will turn upon their pivots, and move back idly over
the inclines, so that the bars will not be raised, and, as a consequence, the sheet or
sheets which have already been moved outward will remain in that position, and
thus the sheets, as they are successively folded will be moved away from beneath
the blade 142, and gradually carried outward to the edge of the platform formed
by the bottom of the casing, from which they can, from time to time, be removed
by an attendant.
If it is desired to deliver the sheets with three, instead of four folds, the arms 121
will be turned down to the horizontal position shewn in Figures 9 and 11, the
rods 130 will be withdrawn from the arms c; d, as shewn in Fig. 11; the arms c
will be turned down to the horizontal position shewn in Figures 9, 10, and 12,
which can be done by raising the section of the piling table, as indicated by
dotted lines in Fig. 13; the arms d will be fixed rigidly to the shaft 143, which can
be done by means of the set screws 110; and the coupling 141 will be loosened,
and the portion of the shaft 143 upon which the blade 142 is mounted, will be
turned, so as to cause the blade 142 and rods 134 to stand further to the rear, when
in their vertical positions, as shewn in Fig. 10. In other respects, the adjustment
of the mechanism will remain the same as already described. When the mechanism
is thus adjusted, the rods 134 and the blade 142 become a fly. The first, second,
and third folds will be imparted to the sheets in the manner already described, and
the sheets will be carried by the blade 150 down onto the upper ends of the
arins d, e, the same as already described, and as indicated by dotted lines in Fig. 11.
When the shaft 143 is rocked, after the withdrawal of the blade 150 from between
the plies of the folded sheet, the blade 142 and the arms d and rods 134 will be
vibrated down to the horizontal position shown in Figure 12, and the sheet, instead
of being folded between the rods 136 by the blade 142, will be simply carried
forward and downward by the blade and the rods 134, and laid upon the bars 123
without receiving its fourth fold.
If it is desired to deliver sheets with only two folds, the fly F will be placed in
position upon the shaft G, as shown in Figure 13, and the switches 119 and
guides 25 will be shifted to the position shewn in Figure 14, so as to direct the
sheets through the opening, and allow them to pass downward in front of the fly.
The rods 130 will be withdrawn from the arms e, and these arms and the arms d,
and the rods which they carry, will be turned down to a horizontal position. The
folding blade 142 will also be turned down to its horizontal position, and secured
by means of a hook 111, or other means, and the sections of the piling table will
be folded down so as to entirely cover the casing K containing these mechanisms, all
as shown in Figures 13 and 14.
The piling table will then present a smooth top, the same as an ordinary piling
table, as shown in Figure 15. In other respects, the adjustments will remain the
same as last described. The sheets, after receiving their secoud fold, will pass
forward between the tapes 6-26, but instead of being directed downward between
the guides 148-149, they will be directed outward, through the opening f, to the
front of the fly, so that when the fly shaft G is vibrated, the sheets, instead of being
folded by the blade 150 between the guides 148, will be simply taken by the fly
and laid upon the piling table H. The sheets may also be delivered with two
folds, by omitting the fly, and leaving the switches 119 in the same position s
when the sheets are to receive three or four folds. In such case, the sheets will
be folded between the guides 148 by the blade 150, and then carried down on to
the piling table by the blade. As the blade is raised and carried upward out from
between the plies of the sheets, the plies will fall outward in opposite directions,
thus leaving the sheets with two folds, and creased upon the line of the third fold.
If it should be desired to always operate the mechanism in this manner, when
delivering the sheets with two folds, then the switches 119 may be replaced by
stationary guides.
If it is desired to deliver the sheets with only one fold, the adjustments will be

page_text: the same as when delivering with two folds, as first described, except that the
clutch upon the shaft 49 will be shifted, so as to throw the folding blade 43 out of
operation, and the blade will be secured in its raised position by means of the
hook 98, or in any other suitable manner, and the rod 74 will be hooked on to the
arm 75, so as to vibrate the pulleys 20. The sheets then, as they are carried
outward by the tapes 4, and brought to rest against the stops 70, instead of being
folded between the rolls 41, will be taken by the pulleys 20 and tapes 5, and carried
over the roll 23, so as to pass downward in front of the fly, by which they will be
piled upon the table once folded.
If it is desired to deliver the sheets in an unfolded condition, the adjustments
will remain the same as last described, except that the clutch upon the shaft 45 will
be shifted, so as to throw the folding blades 42 out of operation.
The rod 74 will be unhooked from the arm 75, and hooked on to the stud 87, and
the stops 69 will be raised out of the path of the sheets. The sheets then will
simply pass forward between the tapes 2-3, and be delivered from between the
rolls 44-57, and pass downward in front of the fly, and be laid upon the piling
table in an unfolded condition.
If at any time it should be desired to divide the sheets upon their longitudinal
centres, or upon the line corresponding to the line of the first fold, the slitter can
be put into operation in the manner described in before mentioned Patent, and in such
case the two halves of the sheet can be delivered in an unfolded condition, or can be
associated by the folding blade 42 and fingers 1, and delivered in that condition, or
with one, two, or three folds, by adjusting the mechanisms in the different ways
already described.
If it should be desired to unite the sheets upon the line of the second fold, or
upon the line corresponding to the second fold, the pasting mechanism can be put
into operation, otherwise that mechanism will be allowed to remain idle.
The organization which has been described embodies the invention in its most
complete and desirable form, but the mechanism may be modified in many
particulars, without departing from some of the principal features of the invention,
and parts of the mechanism may be omittted, and yet preserve certain features of
the invention.
That part of the folding mechanism which is located beneath the feed board may
be changed widely from what is shown, and it may be capacitated to impart only
one fold to the sheets, which single fold will be either at right angles, or parallel to
the impression cylinder; or it may be capacitated to impart two or more folds,
either parallel with, or at right angles to, each other. Or the part of the folding
mechanism which is beneath the feed board may be entirely omitted, without
wholly departing from the invention. In such case, the first fold will be made by
the blade 150. Figures 19 to 21 illustrate two organizations of this character.
The organization shown in Figure 19 is the same as that already described, except
that the part of the folding mechanism located beneath the feed board is omitted,
which reduces the capacity of the mechanism to two folds; the first fold being
imparted by the blade 150, and the second by the blade 142; in this case, the
guides 148, 149 are extended upward to the rolls 44, 57, and the switches 119 are
arranged to direct the sheets as they emerge from between these rolls. The
blade 150 is made longer than in the organization first described, and is, of course,
located in a central position widthwise of the machine. The position and size
of the parts located beneath the piling table are also, of course, changed to
correspond.
The operation of the mechanism, when thus organized, is as follows-If it is
desired to deliver the sheets in an unfolded condition, the switches 119 will be
turned to the position shewn in full lines, the fly F will be secured on the shaft G,
and the parts beneath the piling table will be turned down, and the table will be
folded out so as to cover the casing K.
The sheets will then be taken from the impression cylinder, and carried outward
beneath the feed table by the tapes 2-3, and as they arrive at the rolls 44—57,

page_text: they will be directed outward by the switches 119, and will pass down in front of
the fly, and be piled upon the table in the ordinary way. If the sheets are to
receive two folds, the fly F will be removed, and the switches 119 turned to the
position shown by the dotted lines, and the table H will be folded back, and the
parts beneath it adjusted to the same positions as shewn in Figures 1 to 8.
The sheets will then be directed downward between the guides 148 149, and will
receive the first, and second folds from the blades 150-142, and be laid upon the
bars 123, the same as when they receive the third and fourth folds, and are laid
upon the bars in the organization first described. If the sheets are to receive only
one fold, the parts beneath the piling table will be adjusted to the same positions
as in Figures 9 to 12. The sheets will then receive their first and only fold from
the blade 150, and be laid on the bars 123 by the blade 142 and rods 134, the same
as when they receive their third fold, and are laid upon the bars in the organization
first described.
Figure 20 shows a modification of the organization just described, in which the
switches 119 and guides 25 are omitted. To accomplish this, the guidés 148, 149
are supported so as to have a slight oscillating movement, and the fly is set at such
an angle to the shaft G, that the sheets, as they emerge from the rolls 44-57, will
pass downward outside of the fly, without the aid of special guides. When the
sheets are not to be folded by the blade 15, the guides 148. 149 are moved inward,
as shewn in full lines, so that the sheets will pass outside of them, and of the fly
fingers, but when the sheets are to be folded' by the blade 150, the fly is removed,
and the guides 148. 149 are moved outward to the position shewn in dotted lines,
so that the sheets will pass downward between them.
In Fig. 21, the mechanism illustrated in Fig. 19 for imparting two folds to the
sheets. is shewn as applied to that form of cylinder press known as a "drum cylinder
press." In this style of presses, the impression cylinder is of larger size, and the
fly is located nearer to the cylinder. The sheets, in this case, instead of being
conveyed outward beneath the feed board by tapes, pass directly from the
pulleys 54, which are of somewhat larger size, to the fly, or between the
guides 148. 149. In other respects, the operation of this organization is the same
as of that shewn in Fig. 19. In this case also the switches 119 may be omitted,
and the guides 148. 149 arranged to oscillate the same as in Fig. 20, and for the
same purpose.
If, in any case, it should be desired that the folding mechanism which is located
upon the fly shaft and beneath the piling table, should be capacitated to impart
but one fold to the sheets, the folding blade 142 and its auxiliaries may be
omitted, the jaws 127 being arranged to cooperate with the blade 150. The
bars 123, although very useful, are not essential, and may be omitted, but in that
case the attendant will have to remove the sheets more frequently. It will
sometimes happen, that it will not be desired to have the machine capacitated to
deliver the sheets with less than four folds, or with less than three folds, or with
less than two folds, and in such cases the provisions for adjusting the mechanism
to produce the results not desired may be omitted, and in those cases where it is
not desired to have the machine capacitated to deliver the sheets in an unfolded
condition, or with only one fold, the Hy G need not, of course, be provided.
It will be understood, that while the folding mechanisms above described are
especially adapted for use with cylinder printing presses, as shown, they may be
used also with presses of other classes, or with folding machines acting on the
sheets previously, or as single independent folding machines, the sheets being fed
thereto by hand or any suitable means, and the folding mechanism in itself forms a
part of the invention, however used, except that part located under the feed board
in Figures 1, 2, and 13, which, as above stated. is included in the Specification of
the before mentioned Patent.
In Figures 22 to 35 is shown a modified form of folding mechanism, which may
be used in place of that shown in Figures 1 to 21, the sheets being delivered
thereto as in any of these figures. For the purpose of illustrating the use of these

page_text: folding mechanisms as independent folding machines, however, this modified form
is shown as thus used, the sheets being fed thereto from a feed board, as usual in
'such machines.
This modified form of folding mechanism will now be described.
Referring particularly to Figures 22, 23 and 24, the folding mechanism therein
.shown consists principally of four pairs of stationary guides a b c d', and four
folding blades A B C D', which are arranged to vibrate in the arc of a circle,
from a position on one side of said guides between them, and to a position on
the other side thereof, to effect the folding of the paper. These parts, together
with the minor parts of the machine, are supported in a suitable frame-work G', at
the top of which is arranged the usual feed board H', from which the sheets are
fed by hand to the devices which operate to present them to the folding mechanism.
The devices by which the sheets are presented to the folding mechanism, consist of
a pair of feeding rolls 250, 251, and suitably arranged stationary guides 242, 243, 249.
The roll 250 is mounted in the frame G¹, just below, and at the front edge of the
feed board, and is driven through an intermediate spur wheel 230, which engages
with a gear 231, upon one end of a transverse shaft 252, the opposite end of which is
provided with a gear 232, which engages with a gear 233, mounted upon a stud extend-
ing from the frame G', and provided with a pulley 234, which is connected by a belt 253
with a pulley 254, mounted upon the main shaft 260. The roll 251 is supported in
the ends of arms 255 extending from a transverse shaft 256, and is driven from a
gear 235 upon the shaft 256, which engages with the gear 231, and is provided with
a pulley 236, which is connected by a belt 237 with a pulley upon the shaft of the
roll. One of the arms 255 is located outside the frame G, and is provided with a
pivoted rod 257, which is bifurcated at its lower end, and straddles the main
shaft 260, and is provided with a bowl which is acted on by a cam 258 upon the
main shaft, in such manner as to periodically lower and raise the roll 251 into and
out of nipping contact with the roll 250. The arms 255, which are located inside
the frame G, are connected by a rod 259, which carries ordinary feed gauges 238,
against which the forward end of the sheet rests, before it is carried off the table by
the feed rolls, and which, as the rolls are carried into nipping contact, are lowered
so to be removed from the front of the sheet. The guides 242 are supported, at
their upper ends, on a transverse rod 261, and extend from the upper side of the
roll 250 partly around said roll, and then downward for a distance slightly more
than the length of the sheet to be folded, and are secured at their lower ends to a
horizontal bar 262, which also serves as a stop against which the sheet is brought
to rest, just prior to the making of the first fold. The guides 243 are arranged just
inside of, and a short distance from, the guides 242, and extend upward from the
bar 262 to a point just below the roll 250, as best shown in Figure 32. These guides
co-operate with the guides 242 to direct the sheet downward in proper position in
front of the folding blade which makes the first fold.
The guides 249 are secured to the bar 262, and extend upward from the bar to
points near the ends of the rolls 250. 251. These guides are bent outward at their
upper ends, and serve as side or edge guides to prevent the sheet from moving
laterally as it passess downward between the guides 242. 243.
The following blade A', which operates to make the first fold in the sheet, is, as
shewn in the present case, arranged vertically with it's upper end just below the
feed roll 250. This blade is pivoted, at its lower end, by being fixed to a rock
shaft 266, located parallel with, and below the bar 262, and is arranged to vibrate
in the arc of a circle from the vertical position shown in Figures 22, 23, and 24,
inward, to the horizontal position shown in Figure 25. To impart this motion to
the blade A', the shaft 266 is provided with an arm 239, to the end of which is
pivoted a rod 240, which is bifurcated, and straddles the main shaft 260, and is
provided with a bowl which is acted on by a cam 241, mounted upon the shaft 260,
the cam 241 being so shaped as to impart the necessary rocking movement to the
shaft 266, to vibrate the blade A' downward, as just stated. The return movement
of the blade is effected by a spring 279 on the shaft 266, as shown in Figure 24.
!

page_text: Located just inside the path of travel of the sheets, as they pass downward
between the guides 242, 243, are a pair of vertical stationary guides a', preferably
consisting of simple rods, which are located at a short distance apart, and in such
position that the folding blade A', as it is vibrated inward and downward, will pass
between them.
The bar 262, which supports the guides 242, 243, 249, and the guides a', is
divided at its middle to allow the blade A' to be vibrated up to the vertical position
shown. In order, however, to give strength and rigidity to the bar, its ends are
united by a yoke-shaped portion 223, which passes around the blade when in its
vertical position.
Located at right angles to the bar 262, and directly in front of the blade A', is
a.horizontal bar 263, which is similar in construction to the bar 262. This bar
is located at such a height that it will lie just below the edge of the blade A',
when the latter is vibrated to its horizontal position. This bar is provided with
two pairs of upwardly-extending rods 222, which are located in such position that
the blade A', as it vibrates downward to its horizontal position, will pass between
the rods of each pair. The blade B', which operates to make the second fold in the
sheet, is pivoted at its lower end, by being fixed to a horizontal rock shaft 267,
which is arranged at right angles to the shaft 266, and below the bar 263. This
blade is arranged at right angles to the blade A', and, like the blade A', is arranged
to be vibrated from the vertical position shown in Figure 25, and by dotted lines
in Figure 26, downward to the horizontal position shown in Figures 22, 23, and 24,
and by full lines in Figure 26. To give this motion to the blade B', the shaft 267
upon which it is mounted is provided with an arm 244, which is connected by a
rod 245 with an arm 246, upon a rock shaft 269, which shaft is provided with a
segmental gear 247, which is engaged by a rack upon a vertically-moving rod 248,
which is bifurcated, and straddles the main shaft 260, and is provided with a bowl
which is acted upon by a cam 270 upon the shaft 260, the cam 270 being so formed
as to give the proper movement to the shafts 269. 267, to vibrate the blade B¹
downward, as before stated. The return movement of the blade B' is effected by
means of a spring 280 on the shaft 269, as shown in Figures 22 and 23. The
bar 263 is provided with a pair of vertical guides b, similar to the guides a¹,
which are so located that the blade B', as it is vibrated, as just stated, will pass
between them from one side to the other, the same as the blade A'. This bar 263,
like the bar 262, is divided at its middle to permit the passage of the blade B',
and is provided with a yoke-shaped portion 224, which passes around the blade.
Arranged at right angles to the bar 263, and in front of the blade B', is a third
horizontal bar 264, which is similar in construction to the bars 262, 263, and is
located at such a height as to be just below the edge of the blade B', when the
latter is vibrated downward to its horizontal position. This bar is provided with
two pairs of vertical rods 229, which are so arranged, that when the blade B' is
vibrated downward, it passes between them, the same as has already been described
in connection with the blade A' and rods 222. The blade C, by which the third
fold is made, is pivoted at its lower end by being fixed to a horizontal rock
shaft 268, which is arranged parallel with the shaft 266, and below the bar 204
This blade is arranged to have the same vibrating movement as the blades A', B¹..
To give the proper movement to this blade, its shaft 268 is provided with an
arm 271, which is connected by a rod 272 with an arın 273 upon the shaft 266.
The bar 264 is provided with two vertical guides c', which are similar to, and
arranged the same as, the guides a', 6', so that the blade C will pass between
them in its vibrations. This bar is also divided, and provided with a yoke-shaped
portion 225, similar to the portions 223, 224, and for the same purpose. Located
at right angles to the bar 264, and in front of the blade C, is a fourth horizontal
bar 265, which is arranged at such a height as to be just below the blade C¹ when
the latter is in its horizontal position. This bar is also provided with two pairs of
vertical rods 228, similar to the rods 222, 229, and for the same purpose. The
blade D', by which the fourth fold is made, is pivoted at its lower end by being.
.

page_text: mounted upon the rock shaft 269 before referred to, which is located beneath the
bar 265 The bar 265 is provided with two vertical guides d', which are arranged
in the same relation to the blade D' as are the guides a 'c' to the blades A'B'C',
as already described. This bar is also provided with a yoke-shaped portion 226,
similar to the portions 223, 224, 225, and for the same purpose.
The devices thus far described constitute the principal parts of the mechanism
for imparting four successive folds to the sheets. The remaining details in
the construction of the mechanism will be referred to in describing its operation.
The method for piling or delivering the folded sheets is constructed and arranged
as follows-Located at right angles to the shaft 269, and in front of the folding
blade D is a rock shaft 274, which is provided with two or more upwardly
projecting fingers 216, which, when in their vertical position, lie on the inside of
the folding blade D', when in its horizontal position, as shown in Figure 24. The
shaft 274 is provided with an arm 215, which is connected by a rod 275 with an
Farm 214 on the shaft 268, by which means the shaft 274 is rocked at each vibration
of the blades A, C, so as to throw the fingers 216 forward, as shown in Figure 30.
The shaft 274 is provided with two plates 213; one of which is rigidly secured to
the shaft or to fingers 216, while the other is mounted loosely upon the shaft, and
is. sustained in a vertical position by means of a rod or rods 212, and spring or
Springs 211. When the fingers 216 are in their vertical position, the plates 213
form spring jaws, which lie just in front of the fingers 216. The purpose of these
jaws will appear when the operation of the mechanism is described. The piling
mechanisin is provided with slowly moving tapes 276, passing around pulleys 277, 278,
upon which the sheets are piled, and by which they are carried out to the side of
the machine. The tapes 276 are given the proper amount of movement by means
of a paw 209 upon the arm 215, which engages with the ratchet 210 upon the
.shaft of the pulleys 277.
The
It will be observed that the connections which have been described for operating
the folding blades are so arranged, that the blades A' C' and B', D' are
respectively connected together, so as to be operated simultaneously.
cams 241, 270 for operating the folding blades are so timed with relation to each
-other that these pairs of blades alternate with each other in their operation, that
is to say, the blades A', C¹ are vibrated downward and upward, while the
blades B', D' are in their vertical position, and rice versa. The cam 258, which
-operates the roll 251 and feed gauges 238, is so timed that the roll and feed gauges
will be lowered immediately after the blades A C¹ have been vibrated to their
vertical position, as shown in Figures 22, 23, and 24.
Assuming the machine to be in operation, and the parts to be in the position
shown in Figures 22, 23-and 24, and assuming also that a sheet has been placed
against the feed gauges 238, the operation will be as follows:-The cam 258 will
allow the roll 251 to move downward into nipping contact with the roll 250, and at
-the same time move the feed gauges 238 away from in front of the sheet. The
sheet thus nipped between the rolls 250, 251 will be fed forward off the feed board,
and will be directed 'downward by the guides 242, and pass between said guides
and the guides 243, until its rear edge passes out of the control of the rolls, when
it will fall between the guides 242, 243, until it is arrested by its leading edge
:coming in contact with the bar 262, as shown by broken lines in Figure 25. As
the sheet passes downward between the guides 242, 243, it will be prevented from
ahoving laterally by the guides 249, and will thus be presented in proper position
in front of the folding blade A The bar 262 may, and preferably will," "be
irovided with light spring clips 227, into which the leading edge of the sheet will
fall, and which will press upon the sheet sufficiently to prevent it from rebounding and
liecoming distorted, as it is arrested by the bar 262. As the sheet passes downward
between the guides 242, 243, the cam 270 will operate the bar 248, so as to rock
theshift 267, and raise the blade B from the horizontal position shown in
Figues22, 23, and 24 up to the vertical position shown in Figure 25, and by
-dotted lines in Figure 26, and immediately after the sheet S' has been brought to

page_text: rest, the cam 241 will rock the shaft 266, so as to vibrate the blade A' from the
vertical position shown in Figures 22, 23 and 24, and by dotted lines in Figure 25-
inward and downward to the horizontal position shown by full lines in Figure 25.
As the blade A¹ is vibrated from its vertical to its horizontal position, as just.
stated, it will strike the sheet S' upon its fold line, and double it between the
stationary guides a', and carry it inward and downward between the rods 222, until
its folded edge lies along the bar 263, and at right angles to the blade B' as shown
in Figure 25. As soon as the sheet has received its first fold, and has been carried
to this position by the blade A', the cam 241 will allow the spring 279 to rock the
shaft 266 in the reverse direction, so as to vibrate the blade 'A' back to its vertical
position, and at the same time, by means of the rod 272, rock the shaft 268, so as.
to raise the blade C¹ to its vertical position, as shown in Figures 22, 23, 24, and 26,.
and by dotted lines in Figure 27. In passing back to its vertical position, the blade A
will pass out from between the sides of the folded sheet, thus leaving the once folded
sheet between the rods 222, and between the folding blade B and the guides ..
Any tendency which the blade may have to lift the sheet out from between the
rods 222 upon its upward movement, may be prevented by providing the bar 263.
with one or more spring clips 221, into which the folded edge of the sheet will be.
carried by the blade, and which will grasp the sheet sutficiently to prevent it from
being moved upward from the bar 263 by the upward movement of the blade.
After the blades A', C' have been vibrated upward to their vertical position, as
just stated, the cam 270 will rock the shafts 269, 267, so as to vibrate the blade.B'
from the vertical position shown in Figure 25, and by dotted lines in Figure 26,
downward to the horizontal position shown in Figures 22, 23, and 24, and by full
lines in Figure 26. As the blade B' is thus vibrated downward, it will strike the
sheet S at right angles to the first fold made by the blade A', and will double it.
between the guides 6, and carry it over and downward between the rods 229, until.
its folded edge lies along the bar 264, and at right angles to the blade C, as shown
in Figure 26. After the sheet S¹ has thus received its second fold, the cam 270
will allow the spring 280 to reverse the movement of the shafts 269, 267, so as to
vibrate the blade. 13! back to its vertical position, thus leaving the sheet between
the rods 229 and the folding blade C¹ and guides c¹. At the same time that this.
blade B' is thus vibrated to its vertical position, the blade D' will also be vibrated
to its vertical position, as shown in Figure 27, and by dotted lines in Figure 28..
The bar 264 may also be provided with one or more spring-clips 208, similar to the
clips 221, and for the same purpose. In the meantime, and after the blade A¹ has
been vibrated back to its vertical position, another sheet will have been drawn off
the feed board, and passed downward between the guides 242, 243 in front of the
blade A. After the blade B' has been vibrated back to its vertical position, as.
just stated, the cam 241 will act to again vibrate the blades A', C' downward to
their horizontal position. This will cause the blade A¹ to fold the second sheet in
the manner already described, and at the same time the blade C' will strike the
sheet S upon a line at right angles to its last fold, and double it between the
guides e', and carry it over and downward between the rods 228, until its folded edge
lies along the bar 265 and at right angles to the blade D', as shown in Figure 27
After this takes place, the cam 241 will again allow the spring 279 to reverse the
movement of the shafts 266, 268, and vibrate the blades A, C back to their
vertical position, thus leaving the sheet St between the rods 228 and the folding
blade D' and guides d', and the second sheet between the rods 222 and the blade B₁
and guides The bar 265 may also be provided with one or more spring
clips 207, similar to the clips 221, 208, and for the same purpose. After the
blades A, C have been thus vibrated back to their vertical position, the cam 270
will again rock the shafts 269, 267, so as to vibrate the blade B' downward to its
horizontal position, thus imparting a second fold to the second sheet, the same as
has already been described in connection with the first sheet, and at the same timė
vibrating the blade D' from the vertical position shown in Figure 27 and by dotted
lines in Figure 28, downward to the horizontal position shown by full lines in

page_text: As the
Figure 28. As the blade D' is thus vibrated to its horizontal position, it will
strike the sheet S at right angles to the fold made by the blade C¹, and will double
it between the guides d', and carry it over in front of the fingers 216, as shown in
Figure 28 and by dotted lines in Figure 29, thus making the fourth fold.
sheet is carried downward in front of the fingers 216 by the blade D', its folded
edge will be forced between the spring jaws 213, as indicated in Figure 29, and
these jaws will press upon the paper sufficiently to crease and set the fold, and
prevent the sheet from unfolding. After the sheet has been carried to this
position, the cam 270 will again allow the spring 280 to reverse the movement of
the shaft 269, and raise the blade D' back to its vertical position, leaving the sheet
in the bite of the jaws 213. As the blade D' is vibrated back to its vertical
position, the cam 241 will again rock the shafts 266 and 268, to impart the third
fold to the second sheet, and the first fold to a third sheet, which has in the mean-
time been presented in front of the blade A', and this will cause the rod 275 to
rock the shaft 274, so as to open the jaws 213, and vibrate the fingers 216 forward,
as shown in Figure, 30, and thus lay the sheet over on to the belts 276. As the
shaft 274 is thus rocked, the pawl 209 will engage with the ratchet 210, and move
the belts 276 a short distance, so as to carry the pile of sheets. outward toward the
side of the machine.
It will be observed that the rods forming the guides a¹, b, c, d are cut away,
and rounded on one side, at their upper ends, and also that the vertical rods 222,
229, 228
are bent outward, or spread at their upper ends, as best shown in
Figure 31. This will prevent the sheets from being torn by catching on the ends
of the rods, which might occur if the ends of the rods were left square and abrupt.
The bars 263, 264, 265 are, as shown in the present case, provided with vertical
plates 218, 219, 220, which are curved outward at their upper ends, and are slotted
to receive the ends of the following blades A', B, C respectively. These plates
are not essential, but they serve as side guides for the sheets, and prevent them
from being moved out of proper position in front of the folding blades B, C, D.
A similar plate 217 may be arranged to receive the end of the blade D. It will
often be found highly advantageous to provide the blades A', B, C, D', upon
their folding edges; with one or more fine points 202, as shown in Figure 33, which
will impale the paper as soon as the blade comes in contact therewith, and thus
prevent the sheet from moving lengthwise of the blade. The same results may be
effected by providing the blades at their ends with slight projections 203, as shown
in Figure 34, which will pass over the edge of the sheet, and thus prevent it from
moving along the blade. The bars 263, 264, 265, may be formed or provided with
any suitable means for causing the blades to more perfectly crease the paper, so as
to set the fold.
This last-described folding mechanism may be considerably modified in any parti-
culars, without departing from the essential features of the invention contained therein.
The rods 222, 229, 228, of which there may be any number of pairs, although
they are useful as a support for the sheet, are not in all cases essential, and may
therefore be omitted without departing from the invention. So also the clips 227,
221, 208 and 207, although useful, are not in all cases essential, and may be omitted
without departing from the invention.
It is preferable that the blades A, B, C, D, should be made to vibrate
through an arc of about ninety degrees, but it is not necessary that the blades
should have exactly this range of movement. They may have a greater or less
range of movement. It is also preferable that the blades should all vibrate in
vertical planes, as shown, but this also is not essential.
The guides a, b, c, di will preferably consist of simple rods, and will preferably
be arranged so as to be parallel, or nearly parallel, with the folding edges of the
blades A, B, C, D', when the latter are in their raised position, or in the position
they occupy when the sheet is presented between them and the guides. This,
however, is not essential, as the guides may be arranged at any position between
the blades and the stop bars 263, 264, 265, so long as they operate to fold or

page_text: double the sides of the sheet together across the edges of the blades. One of the
intermediate positions which the guides may occupy is shown by dotted lines in
Figure 25. So, also, these guides, instead of consisting of rods, may be formed by
the edges of parallel, or substantially parallel, plates 298, which are so arranged
that the blades pass between them, as illustrated in Figure 35. In this case, the
edges a' of the plates form the guides for the blade A', and the edges of the slot
in the inner plate, or the edges of a pair of plates similar to the plates 298, form
the guides for the blade B', while the plates also take the place, and are the
equivalent, of the rods 222. It is also to be remarked that the plates 298, instead
of being of the form shown by full lines, may be of less extent, as, for example,
of the form shown by the dotted line g¹, the part above the dotted line being
removed. In this case, the upper edges of the plates will still form the guides
for doubling the paper across the edge of the folding blade. In this case, however,
the upper edges of the plates should be bent or curved outward from each other,
to prevent the sheet from being torn by being drawn across their edges. In any
case, the plates need not be continuous, but portions of them may be cut out, as,
for example, the portions within the dotted lines may be removed.
Although, as herein illustrated, the feeding mechanism is capacitated to impart
four folds to the sheet, it is to be understood that this mechanisin has been selected
merely for the purpose of making the illustration of the invention very full and
complete. The number of folds which the mechanism is capacitated to impart,
is not material. It may be capacitated to impart only one fold, or it may be
capacitated to impart two or more folds. If desired, the mechanism may be so
constructed and organized, that, by slight adjustment, it will be capacitated to
impart either one, two, three, or four folds, as may be desired, at any particular
time, as in the construction shown in Figures 1 to 21.
The particular form of connections which are herein shown for operating the
several folding blades and the piling devices, are of course not material. The
connections shown are well suited for the purpose, but other connections may
readily be substituted for those shown, if preferred. Each of the blades and the
piling devices may be operated independently, and they may be operated in both
directions positively, or they may be vibrated forward and downward by springs,
and returned by cams, if preferred.
In conclusion, it is to be remarked, that it is not intended to limit the scope of
the invention to the precise details of the organization shown, as it is manifest that
these details may be varied in many particulars, without departing from the
essential features of the invention, or losing its advantages.
