Improvements in Printing, Slip-sheet Inserting, and Delivering
Mechanism.
I, WALTER SCOTT, residing at 418. East Front Street, Plainfield, Union County,
State of New Jersey, in the United States of America, Manufacturer, do hereby
declare the nature of this invention and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement:
The present invention relates mainly to that class of machines commonly called
bed and cylinder printing presses: and has for objects the improvement of the
hed-motion; the better distribution of the ink; the securing of perfect register
between the form and the paper on the cylinder; the placing of "slip-sheets'
between sheets delivered from printing-mechanism; the delivery of sheets flat-
wise with the freshly printed side uppermost; the uniform placing of the sheets
delivered; the easy and quick adjustment of margin-tape pulleys on their shafts
to accommodate them to sheets of different widths; the carrying-over of a two
revolution stop-cylinder from the first to the second revolution; a uniform motion
of a bed or reciprocating member (as the bed of a printing-press) during the greater
extent of its motion with a quick, powerful and smooth stopping, reversing, and
starting of its motion at the ends of its strokes; accurate register of the bed and
the cylinder at the beginning of impressions and then equal motions during the
taking of impressions; an even and accurate feed of sheets to the grippers or
other sheet-retainers of a stop-impression cylinder; the avoidance of smearing
of or injury to the sheets while delivering them from the cylinder to a receiving
board; the equal speeds of bed and cylinder at the moment the register-mechanism
engages.
To these ends, the invention includes features of construction and combinations
of devices hereinafter more fully described and pointed out in the claims con-
cluding this specification.
One form of the invention is illustrated in the accompanying drawings, forming
part hereof, in which―

The reference letter A indicates a suitable framework comprising side-frames
and cross-bars or frames, shown in part only. B marks a type-bed which runs
on suitable guides or ways 1, of which two only are partly shown. 2 indicates
rack-bars connected to or formed integrally with the bed on the, under side and
extending lengthwise thereof. 3 marks an ink-table, and 4 a form on the bed.
The bed B is reciprocated to and fro by rolling-gears or pinions 5 which are in
mesh with the racks 2 on the bed and with racks 6 on the fixed framework A.
The gears 5 are mounted on a shaft 7, preferably being fast thereto, and this
shaft is carried by the head 8, being preferably journaled in said head. The
head 8 is provided with a bore in which a shaft 9 is secured, the shafts 7 and 9
respectively being horizontally and vertically disposed. The head 8 is also pro-
vided with a horizontal slot clear across the same and extending beyond the
shaft 9, said slot being for the reception of a connecting rod 10 by which the head
and attached parts are moved to and fro. The rod 10 is adapted at one end to
embrace the shaft 9. as by an eye 11, and at its other end it is provided with a
box 12 for adjustably connecting it with an upright stud 13. The stud 13 is
supported on and carried by a planet" pinion 14, preferably being free to
rotate in a bearing 15 on said pinion. A bushing 16 may be interposed between
the stud or pin 13 and the "brasses" or anti-friction metal 17 in said box 12,
and said bushing may be provided with a flange at its lower end for resting upon
the top of the bearing 15. The pinion 14 is journaled upon a stud 18 which is
suitably secured in a bearing 18" formed in or borne by a carrier-gear, as webbed
bevel-pinion 19. The bevel-gear 19 turns upon an upright stud 20, secured to the
bottom of a casing 21, which in turn is secured to the base of
frame A. The gear 19 is provided with a sleeve 22ª for co-action
with the stud 20. The casing 21 is circular in plan and its walls
are flared outwardly at 22 to provide a track or track upon which the teeth
of bevel-gears 19 may run and be supported. Outside the bevel gear 19, the
walls of the casing are again cylindrical at 23 and 24, the cylindrical portion 24
being of greater diameter than the portion 23. Said cylindrical portions 23 and
24 are connected by a horizontal part 25 of the casing, the top of part 25 being
flush with or just above the flat top of gear 19. An internal gear 26 rests upon
this part 25, and meshes with the pinion 14, which is shown as having a pitch
circle one-half of the diameter of the like circle of the internal gear. Above the
top of the gear 26, the casing is provided with a horizontal external flange 27.
An externally flanged bearing-ring 28 is jogged down over the flange 27; and the
ring 28, casing, and gear 26, are secured together and to the frame A so as to be
stationary or motionless. The gear 14 has an externally flanged ring 29 secured
to its top, the external diameter of the ring 29 being equal to the diameter of the
pitch circle of gear 14, while the internal diameter of ring 28 is equal to the
diameter of the pitch circle of gear 26. The gear 19 has three sets
of pairs of bearing disks or wheels 30, 31 and 32, journaled on studs 33 secured
to or borne by the bevel gear 19. These pairs of wheels are so disposed that their
axes and the axis of the gears are not in one straight line, thus providing for the
adjustment of the wheels touching the rings 29 and 28 to take up any wear.
this purpose, the gear 19 may be provided with slots to receive the journal boxes
of the wheels and with frames for the screws for adjusting such boxes. The
members of each set of bearing-disks coact with each other and one member co-
acts with the inner surface of ring 28 and the other member coacts with the outer
surface of ring 29; in this way the strains are transmitted to or borne by the
ring 28 and the casing 21, and not by the studs or journals of the gears 14 and
For

page_text: 19; there is thus no tendency on the part of these gears to twist or bend their
journals or studs.
The bevel gear 19 is driven by a bevel gear 34 which is fast on a horizontal
shaft 35 journaled in the framework of the machine. The shaft 35 is rotated by
means of a pinion 36 fast thereto, a pinion 37 meshing with pinion 36 and being
fast on a shaft 38 journaled in and extending across the framework on the other
side of the machine where the shaft has a pinion 39 fast thereto. A short shaft 40
journaled in the framework, is provided with a pinion 41 fast thereto which
meshes with pinien 39 and with a pinion 42 fast on a shaft 43, also journaled
in the framework A. The shaft 43 has fast thereto a bevel-gear 44 which meshes
with gear 19, preferably at a point diametrically opposite the pinion 34. It is
understood, of course, that casing 21 is cut away to allow gears 34 and 44 to mesl
with gear 19. The parts are so proportioned that the gears 34 and 44 have the
same speed. By driving the gear 19 from gears placed symmetrically there-
around, undue strain upon its pivot or stud 20 is avoided. The shaft 40 is pro-
vided with fast and loose pulleys, 45 and 46, for coaction with a driving-belt (not
shown).
The point of the teeth of pinions 5 are prevented from running on the bottoms
of the kerfs of racks C by means of the disks or wheels 47 (see Fig. 6) which are
secured upon the hubs 48 of the pinions 5 and by the tracks or ways 49 parallel
to the racks 6; the diameter of the disks 47 is preferably the same as the diam-
eter of the pitch-circles of the pinions 5. The tracks 49 may be integral with the
frame or may be attached thereto.
As it is shown in the drawings, the pin or post 13 is at all times within the
pitch-circle of the gear 26; this is the preferred arrangement, however, as it
allows of comparatively shallow gearing for driving the bed, and so decreases
the height of the machine. It is obvious, however, insofar as certain features of
my invention are concerned, that the post 13 could be arranged with its axis
intersecting the pitch-circle of gear 26 at right angles to the plane thereof, in
which case it would, with the described proportions between gears 14 and 26,
move in a straight line across the gear 19, and there would be no need for the
vertical pivot 9 for the rod 10. In the particular case shown, however, the pivot 13
does not move in a straight line across the gear 19, but in two curved lines, one
of which lies on one side of that diameter of the gear 19 which is parallel to the
direction of motion of the bed, and the other of which lies on the other side of
said diameter. Also, the post 13 could be, insofar as certain features of my in-
vention are concerned, in its position at greatest distance from the center of
gear 19, outside the pitch-circle of gear 26. In every case, however, the bed is
easily, powerfully and slowly started, and the motion increases to a maximum
rate of speed and decreases to a slow, easy and powerful stop as the pin 13,
pivots 9 and 20, come into line with each other.
The shaft of the impression cylinder C is journaled in suitable boxes in the
slides 50 (but one of which is shown). The cylinder C is held up by springs 51
which are interposed between studs 52 on the frame, or screws in said studs, and
the top cross pieces of the slides 50, as in Figure 1. Near their lower ends, the
slides 50 have a rock-shaft 53 suitably journaled therein. The shaft 53 is pro-
vided with an arm 54 to which one end of a bar 55 is pivoted at 56; the other
end of bar 55 is pivoted with a gab-hook 57, adapted to engage over a pin 58 on a
lever 59. The lever 59 is pivoted at 60 to the frame A and has an arm provided
with an anti-friction roller or a stud 61 which works in a grooved cam 62. The
cam 62 is formed in one face of a gear wheel 63, carried by the shaft 64, journaled
in the framework of the machine. The gear 63 is driven by a gear 65 on the
shaft 43 above named. The shaft 53 is provided with an arm 66 which is adapted
to coact with two opposite stops 67 and 68 on the base of the frame A to limit
the rocking motion of shaft 53. At each side of the machine, a toggle 69
connects the shaft 53 with an adjustable abutment 70 on the side-frame. Ono
member of each toggle is rigidly attached to the shaft 53, and the other member

page_text: thereof bears pivotally at its end against the corresponding abutment 70. The
members of each toggle are suitably connected together. An adjustable stop 71
on the frame limits the downward motion of the slides 50.
The impression cylinder C is started and stopped by an independent starting
and stopping mechanism of suitable construction, such, for instance, as that shown
in British Letters Patent granted October 3, 1893, and numbered 18496. The
starting and stopping mechanism shown herein see Fig. 4 comprises a toothed
segment 72 connected to the cylinder C; a starting and stopping bar 73 which is
pivoted at one end 74, to the frame A, and whose other end is provided with a
curved segmental rack 75 which is adapted to mesh with the curved rack 72; a
link or connecting rod 76 pivoted to armi or bar 73 at 77; a rocker-bar or frame 78
which is pivoted to the irame A at 79, and is provided with two anti-friction
rollers 80 and 81, and to which the rod 76 is pivoted at 82; positive and negative
canis 83 and 84, the positive cam coacting with roller 81 and the negative cam
with roller 80 to move frame 78 to and fro; said cams being fast on shaft 64, and
being shaped to move the bar 73 as hereinafter described.
For the purpose of tripping the impression cylinder, means for throwing the
gab-hook 57 out of gear with the pin 58 are provided. The particular means
shown for this purpose comprise the bent lever 85 pivoted at 86 to the frame A,
and provided at one end with a pin 87 which lies under and across the link 55
in position to raise the same; the cam SS on the other end of the lever 85, adjacent
the cam gear 63; and a pin or stud 89, movable transversely of gear 63 and so
placed that it will, when pushed out against the force of a returning spring (not
shown), come in contact with the cam 88 and depress that end of lever 85 and raise
the other end thereof with pin 87 to lift the bar 55 and free hook 59 from the
pin 58, whereupon springs 51 raise the cylinder C. The weight of link or
rod 55 bearing on the pin 87, suffices to move the lever 85 on its fulcrum 86 to
lower the hook 57 into the path of pin 58 and so re-engage the pin 52 and hook 57.
The pin 89 is operated by a suitable foot-lever mechanism and cam.
The cylinder C is provided with spur pinions 90 at the ends thereof, which
pinions are mutilated or have certain teeth removed in whole and in part at 91.
and the bed B is provided with racks 92 for intergearing with the pinions 90 to drive
the cylinder C. When the pinions 90 are in that position which brings the
mutilated portions thereof underneath, the racks 92 are clear of the gears and may
move back and forth freely without moving the cylinder C, it being assumed
that the cylinder-starting and stopping mechanism herein before described is
inactive or inoperative. During the normal operation of the machine, it is
requisite that the cylinder C make two complete revolutions to each forward or
printing stroke of the bed B. For the purpose of carrying over the cylinder U
from the first to the second of such revolutions, a toothed segment or sector 93 is
connected to the cylinder C at one end thereof and opposite or alongside the
mutilation 91 of the gear 90 at that end of the cylinder C, and an up and down
movable short section of straight rack 94 is provided and guided on that side of
bed B adjacent to the segment 93, said rack 94 being alongside the corresponding
rack 92 and at the central point of the bed B. This rack 94 may be raised and
lowered, in so far as certain features of my invention are concerned, by any
suitable means, or the rack 94 and operating parts may be wholly omitted, and the
cylinder C be carried over from the first to the second revolution by any other
suitable means, such, for example, as are claimed in my Letters Patent No. 18496
dated October 3, 1893. Referring to the drawings, the rack 94 is at the top of a
plate 95 with which the lifting toe or cam 97 coacts underneath the same." The
cam 97 is preferably so shaped or curved that it lifts the rack 94 and allows it to
fall of its own weight as the cam moves from under it. The cam 97 is carried by a
sleeve 98 and the sleeve is loose or pivoted on a stud 99 which is secured to the
side of the bed B; the sleeve 98 is also provided with an arm 100 which is
provided with an anti-friction roller 101 loosely mounted on a crank-pin on said

page_text: arm. The roller 101 works in a channeled bar 102 which lies parallel to the
direction of motion of the bed B and is provided with lugs 103 near the ends
thereof. These lugs are shown underneath the bar 102 and are pivotally con-
nected with bars or arms 104 which, in turn, are pivotally connected to the
frame A, and are of equal lengths between said pivots, thus providing a parallel
motion for the bar 102. One of the bars 101 is provided with an extension 105
and the extension or arm 105 is provided with an anti-friction roller 106 at its
free end. The roller 106 is engaged by a closed cam 107 fast on a rotatory
shaft 108, which extends longitudinally of the machine, and is driven as herein-
after described. The cam 107 swings the arm 105 to and fro in the direction of
the length of the machine (the pivots of the arms 104 and 105 being horizontal and
transverse of the machine), and so causes the bar 102 to be raised and lowered.
The bar 102, through the described connections, causes the rack-plate 94 to be
raised, and the weight of the plate brings it down whenever the cam 97 is rocked
downwardly by the raising up of bar 102; or the rack 94 may be moved up and
down positively.
The form 4 on the bed B, which may be lithographic, letterpress, or other
form, is inked by means of rollers I distributing rollers D, ink-table E (the
fountain and ductor are not shown), and the vibratory rolls F and G. The
vibratory rolls F and G are moved endwise to and fro by any usual or suitable
means (not shown), and are oscillated, preferably by the following means: the
frame A has a channeled guide bar 109 fastened thereto, as by means of
brackets 110 (see Fig. 6) said channel-bar 109 being adjacent and parallel to the
path in which the gears 5 reciprocate. A rack-bar 111 reciprocates in the channel-
bar 109, being moved to and fro by the carriage-driving mechanism, to which it
is connected by means of an arm 112, having an eye 113 fitting over the hub 48
of the nearest pinion 5. A transverse-shaft 114 journaled in the frame A, extends
near and over the rack-bar 111 and is there provided with a spur-pinion 115 which
meshes with the rack, the channel-bar 109 being suitably recessed or cut away at
that point to allow of the pinion intergearing with the rack. Near its other end,
the shaft 114 is provided with a spur-gear 116, see Fig. 2. The vibratory rolls F
and G are provided with spur-gears 117 and 118, and these gears are driven from
the oscillatory gear 116 by the trains of gears 119 and 120. The gears 117 and 118
are splined or otherwise attached to the shafts of the rolls and G to allow
these to move to and fro endwise independently of the gears which are so mounted
in the frame of the machine that they have oscillatory motion only (means not
shown); or these gears 117 and 118 are fast to their shafts and are of a width
sufficient to permit the endwise movement of the shafts and rolls without dis-
engaging these gears from those with which they mesh. The rolls F and G are
thus given oscillatory motion, and in turn drive the ink and distributing rolls I
and correspondingly. The ink being spread on the table by the rolls G is in
turn transferred to the form-rolls I in front of and behind the cylinder C, and
by those rolls to the form. When printing from stone or aluminium by litho-
graphic process, damping rolls replace one set of inking rolls so as to dampen
the printing-surface after printing and before inking it.
For the purpose of perfecting the register and avoiding or preventing lost motion
between the type-bed and the impression cylinder, the racks 92 are preferably
formed as shown in Figure 7; that is, the racks 121 are straight for a distance
or length equal to the travel of the cylinder while down (i.e., from c to d), and
are bent upward at the end 122 thereof which meshes with the gears 90 at the
commencement of the forward or printing stroke of the bed. The amount of the
rise of the pitch line of the rack is equal, preferably, to the lift of the cylinder,
or the amount of motion up or down of the cylinder. If desired, both ends 122
and 123 of the rack 121 may be bent up. The bent-up ends of rack 121
may be straight or curved, according to the speeds of the bed and the rising and
falling cylinder.

page_text: Assuming that the parts are in the positions shown in Figures 1, 2 and 3, or
their positions at or just as the bed is beginning a printing stroke, the operation
of the parts as follows:
The fast pulley 45 drives the shaft 40, and this shaft, through the gears 41, 42,
shaft 43, pinions 65 and 63, shaft 64, and cams 83, 84, operates the cylinder
starting mechanism, or lever 78, rod 76, lever 73 and toothed segment 72, and
starts the cylinder rotating; the directions of motion of the parts at this time are
indicated by the arrows. At the same time, the shaft 43, through the bevel
gear 44, and the shaft 40, through the pinions 41 and 39, drive the gear 19 in
the direction indicated in Figure 3 by the arrow a. The cylinder lowering
mechanism is operated by the cam 62 to lower the cylinder against the force
of springs 51 into position for its gears 90 and segment 93 to coact with the
racks 92 and 94, the cylinder being started to rotate as stated above, in order
to bring the toothed portions of the gears 90 into mesh with the racks 92, after
which the gear segment 72 rolls out of mesh with the teeth 75 of the starting
arm 73. The rotation of gear 19 carries the pinion 14 along with it, and the
engagement of the teeth of gear 14 with the teeth of the fixed internal gear 26
rotates the gear 14 and moves the stud or post 13 toward and to one side of the
center of the gear 19, so that by the time the gear 19 has made one-quarter of a
turn, the stud 13 is at a distance from the center of gear 19 equal to its own
distance from the pitch circle of gear 14, and by the time the gear 19 has mado
a half turn the stud 13 is again at its farthest distance from the axis of gear 19
but diametrically opposite to its position in Figure 3. During the movement
of the stud 13 from the position shown in Figure 3 to its diametrically opposito
position, the rod 10, gears 3, and racks 2 and 6 start the bed with an increasing
motion which reaches its maximum when the gear 14 has made a half turn, after
which the said motion decreases to nothing as the gear 14 completes its turn, or
the stud 13 reaches a point diametrically opposite its position in Figure 3. As
the gear 19 moves the pinion
14 back to the position shown in
Figure 3, the bed is moved back to the position thereof shown in Figures 1,
2 and 3. During the forward stroke of the bed, the vibratory distributing
rolls F and G are driven continuously by the gears or pinions 117 and 119, and
118 and 120, the pinion 116, shaft 114, gear 115 and rack 111, the last being
moved along by the bed-driving mechanism. Also during this stroke of the bed,
the cylinder makes two complete turns or revolutions, the rack 94 being raised
by the cam 107, the levers 104 and 105, channel bar 102, and cam 97, into posi-
tion for coaction with the segment 93 to carry the cylinder over from the first
to the second revolution thereof, or when the cut away parts 91 of gears 90 are
underneath and over racks 92. The cams 83 and 84 are so shaped and so placed
that, through the lever 78 and rod 76, arm 73 is moved to the left in Figure 1
far enough to be in position to roll into mesh with the toothed segment 72,
and brings the cylinder C to rest at the completion of its second revolution.
During the return stroke of the bed, the cylinder starting and stopping
mechanism, and the raising and lowering mechanism are motionless, their operat-
ing levers 59 and 78 coacting, at this time, with the "dwells" of the cams 62
and 83, 84. Also, at this time, the cam 107 (whose shaft 108 is pivoted with
a worm-gear 124 which is driven by a worm 125 on the shaft 35), has operated
the arm 105 and connections to cam 97 to allow the rack-section 94 to move down
so that it will pass below segment 93. During the return stroke of the bed
the rolls F and G are driven in the direction opposite to that in which they were
driven during the forward stroke of the bed
Obviously, the stud 20 may be omitted, and the gear 19 may revolve on the
track 22, or it may fill the lower part of the casing and be supported thereby,
and by track 22 also. Many other changes may be made in parts and elements
of combinations without departing from the spirit of my invention, which is not,
therefore, limited to the form thereof shown in the drawings and hereinbefore
described.

Fig. 23 is a side elevation of the mutilated cylinder driving gear and a portion
of the bed rack; Fig. 24 includes a like view but with the segments of a gear
and a rack for continuing a two-revolution cylinder over from the first to the
second revolution thereof, and an edge view of the same.
In the arrangement shown in Figs. 23 and 24, the gear 13 on the cylinder C is
cut away or mutilated at that part thereof which lies opposite the rack R when
the cylinder C is at rest. There is a toothed segment 150 fixed to the face or
side of gear 13 opposite the mutilated portion thereof, and the rack R has fixed
thereto. at its middle portion, a rack segment 151 for coaction with the seg-
ment 150. By preference, the teeth of segment 150 are shorter than the teeth
on gear 13, and the teeth of rack segment 151 are shorter than the teeth of
rack R, as this permits of a shorter lift to the cylinder C to clear the rack seg-
ment 151 during the return stroke of the bed.

The same part will be found designated by the same character of reference in
all the figures of the drawings in which it is shown.
The reference letter A indicates a suitable frame in which the working parts
are mounted for operation. B marks a delivery-board which is supported at its
sides upon horizontal flat bars 1, and is connected therewith by means of a pin 2,
fast to the board, and a hole 3 in the bar 1 into which the pin enters, there
being, preferably, one such pin-and-hole connection at each side of the board.
By lifting up the end of the board, the pins are withdrawn from the holes and
the board may then be slid along on the bars, as toward the cylinder, the pins
resting on the bars; this arrangement provides for getting at the inking appa-
ratus without hindrance from the overhead delivery-board.
Cindicates the impression-cylinder, which may be driven in any usual or
suitable way it may oscillate, revolve continuously, or stop, as circumstances
may require. The sheets may be fed to the cylinder C in any suitable or
desired manner, and are then delivered thereby upon the fixed guides 4 and
between the sets of tapes 5, 6. The tapes 5 are carried by the rollers or

page_text: pulleys 7, 8, the first of which are journaled in the frame adjacent to the impres-
sion-cylinder C and the second of which are journaled in the frame at a distance
from the cylinder C. In some cases, it is advisable to provide that the sheet
shall not be lifted or blown from the tapes 5, and for the purpose of preventing
such mishap, the tapes 6 are provided. By preference, the tapes 6 only bear
upon the margins of the sheets. The tapes 6 are carried by rollers or
pulleys 9, 10, the first of which are journaled over the pulleys 7 and the second
of which are shown as being journaled in the frame over the pulleys 8. The
tapes 5, 6 are driven in any suitable way (not shown).
From the rollers or pulleys 8, 10, the sheets are, in the specific embodiment of
my invention shown in the drawings (Figs. 8, 10, 11 and 12), run upon the
web or ribbands 11, of fabric, one end thereof being fast to the cross-bar 12
on the fixed frame of the machine, and the other end thereof being fast to a
hollow roller 13 on a to and fro movable carriage. This carriage is composed of
end pieces 14 (but one is shown), which are tied together by means of a bar 15
fast at its end to lugs 16 on the end pieces 14 and a bar 17 fast at its ends to
said end-pieces. The end-pieces 14 are provided with suitable bearings for a
shaft 18 on which the roller 13 is loosely mounted so as to turn independently
thereof, and with bearings for the ends of a bar or shaft 19 which carries part
of the sheet-gripping mechanism, as will presently appear. The shaft 19 lies
between the roller 13 and the bar 15 and is provided with an arm 20 below it.
The arm 20 is bent as shown and is provided with an anti-friction roller 21,
and with a stud or bearing 22 on which a bar 23 is provided. The adjacent
end-piece 14 is provided with a perforated lug 24 through which the bar 23 pro-
jects; a spring 25 is coiled around the bar 23 between the lug 24 and the
enlarged end thereof which is pivoted upon the stud 22, and acts to press the
arm 20 away from the lug 24. The arm 20 is stopped, when free to move, by
coming in contact with a lug 16 or an adjustable stop 26 passing through the
bar 15 and the lug 16; or any other adjustable stop may be used. By prefer-
ence, the gripper carried by the bar or shaft 19 is in the form of a continuous
bar or plate 27, though this may be replaced by two or more flat bars or grippers.
The gripper 27 is in front of a sheet-stop 28 which is secured to the bar 15 and
projects above the same. When the bar 19 is free to move under the influence
of spring 25 and the arm 20 is stopped as described, the top surface of the
gripper 27 is flush with or slightly above the top of the stop 28; or it may be
held flush with said top and afterward be raised slightly above the same; all
as will hereinafter more fully appear. By rocking the shaft 19 in one direction,
the gripper 27 may be depressed below the top of the stop 28. Above the stop 28
is the gripper or set of grippers 29; this set of grippers is borne by a shaft 30
which is journaled in arms 31 from the shaft or bar 17. The shaft 30 is provided
with an arm 32, to the end of which a rod 33 is pivoted; the other end of
rod 33 passes loosely through a lug 34 on the adjacent end-piece 14, between the
enlarged end of the pivoted end of the rod 33 and the lug 34, and tends to move
the shaft 30 one way or the other according as the pivot connecting the arm 32
and the rod 33 is above or below the line joining the centers of shaft 30 and the
hole in lug 34, as will be understood. The shaft 30 is also provided with an
arm 36 by which it is moved or rocked when it is desired to open or to close
the grippers 29. This arm 36 has a lug 37 at one side thereof for coaction with
a fixed or adjustable abutment 38 on the frame A, and with an arm 39 to which
an anti-friction roller 40 is attached. The abutment 38 acts to close the
gripper 29 down upon the top of stop 28, and a lifter 41 coacts with the roller 40
to raise the grippers 29 from said stop-top. The lifter 41 is, preferably, an armi
on a shaft 42 which is suitably journaled in bearings on or borne by the frame A ;
the shaft 42 is rocked at suitable times to cause the arm 41 to lift the roller 40
and so cause the shaft 30 to rock until the pivot connecting arm 32 and rod 33
is above the line of centers referred to above, whereupon the spring 35 completes
the motion of the shaft 30. The shaft 42 is provided with an arm to which a

page_text: rod 43 is pivoted; the rod is connected with a suitable cam or other part (not
shown) by which it is moved at the appropriate times to cause the arm 41 to
rise, as above described.
The hollow roller 13 may be rotated in any suitable manner, as by means of the
fabric 11 and a tape 44, which may be secured to the roller at one edge of the
fabric and to a roller or pulley 45 which is journalled on the framework A and
is connected therewith by a spring coiled about the shaft on which the pulley
is journalled and having its ends fast to the frame and to the pulley (spring not
shown).
The carriage carrying the roller 13 may be reciprocated by any suitable
mechanism, such as is partly shown herein. The end-pieces 14 are provided
with rollers 46 which run on the smooth backs of a pair of racks 47 (but one is
shown) at the sides of the machine. The shaft 18 is provided with pinions 48 at
its ends (but one such pinion is shown) which mesh with the racks 47; the shaft
also has a pinion 49 fast thereto at one end, and this pinion 49 meshes with a
reciprocating rack-bar 50 which is suitably guided on the frame A. The rack 50
is driven to and fro by means of a gear 51 on a shaft 52 journalled in frame A; the
shaft 52 is provided with a second gear 53 which is driven by a reciprocating
rack 54 working in a guide-way 55 bolted to the frame A in an oblique position,
and driven from a crank or cam (not shown).
The operation of the foregoing devices is as follows: The sheets are run out by
the tapes 5, 6 onto the web 11 and between the grippers 27 and 29, which at
this time are in the relative positions shown in Fig. 10, and against the stop 28.
The sheets may reach the stop 28 at the moment the carriage is reversing its
motion or at any time thereafter prior to the time when the roller 21 runs from
under the cam 56 and so permits the spring 25 to move the gripper 27 up against
the gripper 29 as shown in Fig. 11. After the closing of the grippers, the sheet
is drawn out over the supporting web 11 until the carriage reaches the limit of
its movement away from the impression-cylinder C. As the carriage comes to
rest or while it is at rest, the lifter 41 raises the roller 40 and rocks shaft 30 as
described to open the grippers 29; that is, these grippers are lifted from the top
of the stop 28 and the sheet is now free to pass over the stop and onto the board B
during the return movement of the carriage. Accordingly, as the fabric 11 is
now wound up on the roller 13 through the action of the tape 44, the sheet drops,
head first, onto the board B and against the end-stop 57. As the carriage reaches
the end of its return movement, the arm 36 or lug 37 is acted upon by the abutment
38 and the gripper 29 is thrown down against the top of the stop 28, while the
gripper 27 was moved down by the cam 56 in ample time for the sheet to be run
out as in Fig. 10.
66 X 99
The devices shown in Fig. 12 will now be described. The means for running
out the printed sheets may be identical with those hereinbefore described; hence,
no further description thereof is required. In case "slip sheets"
are to be
inserted between the sheets so run out, almost identical mechanism may be used
for the purpose of carrying out such "slip sheets" and laying them on the sheets
on the board B. In case the slip-sheets are to be fed by hand to the grippers 58
and bar 15, a feed board 59 is provided, and the shaft carrying the grippers 58
is placed so that the bar 15* is between it and the shaft 18 (all the parts having
the superior are or may be identical with the like parts herein before described
and referred to without the "superior "*" to their references, and, therefore, do
not need further description). The carriage for the slip-sheet delivering
mechanism may be driven independently or it may be connected, at each side, to
the end piece 14, as by the bars 60 and the screw bolts 61 connecting the bars
with the end-pieces 14. The grippers 58 may be opened and closed in any suitable
way, such, for example, as that herein shown, or they may be connected with the
grippers 29 as by a rod 62 which is pivotally connected with arms on the shafts
of the said grippers 29 and 58. The slip sheets are dropped on the board B and
against a stop 63 in substantially the same manner as the sheets from the printing

page_text: press. It will be observed that the two mechanisms deliver their sheets in
alternation, one beginning at one end of the board B and the other at the other
end thereof.
The feed-board 59 may be adjustable toward and from the cylinder C as may
also be the stop 63, thus providing for cases where the sheets delivered from the
printing press vary in length. In such cases, the rods 60 and 62, may be replaced
by others of the proper length to cause the grippers 58 and their carriage to have
the proper position to drop the slip-sheets (of nearly the same length of printed
sheets) upon the printed sheets on the board B...
In Fig. 13, the feed-board 59 is replaced by a feed-cylinder 64 which is journaled
in brackets 65 bolted to the top of frame A at each side of the machine. The
cylinder 64 is provided with grippers 66 which are operated at suitable intervals
by any appropriate means (not shown). The sheets are fed to the cylinder 64
from a feed board 67 above the same and pointing away from the cylinder C (the
board 59 points toward said cylinder C) thus saving space, as compared with the
arrangement in Fig. 12,
The slip sheets are fed by hand from the board 67 to the grippers of cylinder 64
and are delivered by the grippers 66 to the grippers 58 and bar 15 at the moment
these begin to move toward the cylinder C.
The cylinder 64 is driven by any suitable mechanism (not shown) and takes the
sheets from the board 67 and delivers them to the grippers 58 and bar 15*, the
cylinder being so driven at this time as will secure that the slip or other sheets
shall be taken by the reciprocating delivery without undue strain being brought
upon the sheets; for this purpose, the cylinder 64 may be caused to move at the
same speed as the reciprocating and delivery mechanism during the time it is
delivering the sheet thereto. At other times the cylinder 64 may be at rest or
move progressively as may be desired. I have not illustrated the mechanism for
driving the cylinder 64, inasmuch as one skilled in the art can supply the same
without further directions.
The cylinder 64 and board 67 may be adjusted toward and away from the
cylinder C, to meet the cases where the lengths of the sheets vary, as by removing
the bolts 68 by which brackets 65 are secured in place and moving the parts
along on the frame A to another set of threaded holes 69 and attaching the
brackets there to the frame A, and also changing rods 60 and 63 for others of the
proper length.
In the modification illustrated in Fig. 21, the stop-plate 28 is provided with
notches 70 opposite the grippers 29; that is, the grippers 29 are not stopped by
the stop-plate but by independent means, as a stop 71 (Fig. 10) in the path of the
arm 36 or the grippers 29. The gripper 29 is replaced by a series of fingers 27.
The dotted line indicates the position of a sheet before the grippers 27* close.
In the modification illustrated in Fig. 22, the grippers 29 and 27 are not
placed opposite each other, but the grippers of each set are placed at opposite
intervals between the grippers of the other set, and the parts have motion such
that the upper surfaces of the grippers 27 rise somewhat above the plane of the
lower surfaces of the grippers 29 when both sets are in position to grip sheets,
thus bending the sheet as indicated by the dotted line in said Fig. 22, and
holding it.
It is stated above that it is preferred that the tapes 6 shall bear only upon the
margins of the sheets. In order to provide for carrying out sheets of various
widths between the tapes 5 and 6, I arrange to have the pulleys carrying one
or more sets of such tapes 5 and 6 adjustable along their shafts, The means,
forming part of the present invention, whereby this adjustment is readily secured,
are shown in Figs. 17, 18, 19 and 20. Inasmuch as the device is applicable to
all the shafts and pulleys. I shall in these figures give independent reference
numerals to the parts. The shaft 72 is provided with a feather or spline 73, and
this feather or spline is provided along its length with transverse notches 74.
The pulley 75 is provided with a groove 76, to fit over said spline, whereby the

page_text: pulley is prevented from turning independently of the shaft. The pulley is
provided with a perforation from its rim to its bore, said perforation opening into
the said groove 76. Slidable in said perforation is a pin 77 having one end shaped
to fit the notches 74 and the other end shaped to receive the end of a coil spring 78
lying behind the said pin in the said perforation. A screw 79, engaging the
threaded end of the perforation, acts as an abutment against which the said
spring 78 bears. When it is desired to adjust the tape pulley 75 along the shaft,
it is only necessary to press with some force upon one side of the pulley and thus
cause the pin 77 to move radially outward of the pulley against the force of the
spring and jump over into the next notch 74 as the pulley moves or is forced along
the shaft. In this way the pulleys and their tapes may be adjusted along the
shafts to suit any width of sheet and bear upon the margins or other parts thereof,
as may be desired.
In the modification shown in Fig. 20, the spline is omitted and the shaft 72
is provided with a groove 80, whose bottom is notched at 74 to receive the pin 77.
The pin 77 in this instance acts as a means of preventing the shaft and the pulley
from rotating independently of each other; that is, the pin has a function making
it the equivalent of the spline. By preference, the notches 74 are flaring, as by
being conical, and the pin 77 is shaped to fit them; or the notches 74 may be of
the same width all the way across the spline or groove, and pin 77 may have a
wedge-shaped end to fit them; or the notches may have other cross-sections and
the pin be shaped to fit them. The essential point is that the shaft and wheel
shall have coacting members, at least one of which shall present a concave or
convex surface to the other.
Referring now to Figs. 33 to 39 inclusive:

The reference letter A designates a suitable framework for supporting the
various parts of the machine, and B marks a suitable framing for the support
of the delivery mechanism, the frame B being suitably attached to and supported
by the frame A. C is the impression-cylinder (and, also, the pitch-circle of the
driving gear for the impression-cylinder) which is shown as being provided with
grippers 2, though any usual or suitable form of sheet-retainers may be used
thereon, as may be also sheet-lifters for directing the sheets from the impression-
cylinder upon the fixed guides 3 adjacent to the cylinder at the delivery side
thereof. The impression-cylinder may be prevented from touching the form or
forms on the reciprocating bed (not shown) in any suitable way, as by being
lifted. In the present instance, the cylinder C is driven by a gear or pinion 4
journalled in the framing A beneath the cylinder and which is driven in any
suitable way. The sheets are fed to the grippers 2 by hand or in other ways. The
printed sheets are run by the guides 3 upon the tapes 5 running on pulleys or

page_text: rollers 6 7. The pulleys 6 are carried by a shaft 8 which is journalled in
brackets 9 bolted to the frame A at each side of the machine, and the pulleys 7 are
carried by a shaft 10 which is journalled in the frame B at each side of the
machine and preferably at a height somewhat above that of the shaft 8. Adjunc-
tive devices above the tapes 5 may be used, if desired, to ensure that the sheets
shall not lift or rise as they are run forward, as, for example, a set or pair of
tapes 11 which may bear only on the margins of the sheets. The tapes 11
are carried by rollers or pulleys 12 13, the first of which are carried by
a shaft 14 journalled in the brackets 9 and the second of which are carried by
shaft 15 journalled in the frame B at each side of the machine, or in boxes 16
on endwise-adjustable rods 17. By having the tapes 11 at a little distance from
the tapes 5, the operation of drawing the sheets from between the two sets of
tapes is much facilitated, especially if, as may be the method of operation in some
cases, the tapes 5 and 11 are stopped or set at rest all or part of the time during
which the sheets are pulled from between them. The devices thus far described
are or may be of usual or suitable construction.
a
From the pulleys 7 and 13, or the tapes 5 and 11, the sheets pass to the delivery-
mechanism shown. This mechanism includes a to and fro moving carriage 18
which is provided with rollers 19 running on suitable guides or ways on the
frame B. The carriage 18 is composed of end-pieces 20 21, to which the rollers 19
are connected by their journals and the arms supporting said journals; and two
cross-bars 22 23. The cross-bar 22 consists of a shaft which is bolted or
otherwise secured to the ends 20 21, as by the set-screws 24 which pass through
and engage threaded holes in the ends 20 21 and bear against the shaft 22 (see
Figure 35). The cross-bar 23 consists of a bar having a flat top 25 and is bolted
or otherwise secured to lugs 26 on the end-pieces 20 21. These end-pieces are
provided with bearings 28 for a transverse shaft 29, and this shaft is provided
with equal spur gears 30 31 at or near its ends and fast to the shaft; these
gears respectively mesh with the racks 32 33, fixed to the frame B.
racks 32 33 afford convenient ways or tracks for the rollers 19 of the carriage 18,
These
which run upon their smooth tops or backs. At one end, the shaft 29 is provided
with a sleeve which may be an extension or hub of the gear 30, and on this sleeve a
spur gear 34 is made fast. The pinion 34 meshes with a to and fro moving
rack 35 which is suitably guided on the frame B, as indicated in Fig. 34. The
gear 34 is of a width sufficient to take up about one-half the width of rack 35
only. A gear 36, fast on a shaft 37 which is journalled in the frame B, meshes
with the rack 35, the gears 34 and 36 being, in the instance shown, in different
planes with respect to the rack 35. The shaft 37 is provided with a second
gear 38 fast thereto, which gear meshes with a reciprocating rack-bar 39 moving
in a guide-way 40 secured to the frame B in an oblique position. The shaft 37
has a collar 41 fast thereto which lies between the gear 36 and the frame B thus
preventing the shaft from moving in one direction endwise, while the gear 36
prevents the shaft from moving endwise in the other direction, the gear 36 and
collar 41 being at opposite sides of the piece of frame B in which the shaft is
journalled.
The rack-bar 39 is preferably moved to and fro by the following means:
A shaft 42 is journalled in the framework A near the base thereof and is provided
with a gear 43 fast thereto. The pinion 43 is driven from the gear 4 through the
pinions 44 45 fast on a shaft 46 which is journalled in the frame A, the pinion 4t
meshing with the pinion 4 and pinion 45 meshing with the pinion 43. As pro-
portioned in the drawings, the pinion 43 is equal to the gear on the impression.
cylinder C, while the pinion 44 is twice the size of the pinion 45; the size of the
gear 4 is immaterial. The shaft 42 is provided with a crank 47 which is integral
with or attached to a disk 48 fast on the shaft 42. A strengthening arm 49 may
be formed on the disk between the hub thereof and the crank-pin 47. The
shaft 42 is preferably journalled in the framework A, relatively to the line of
motion of the rack 39, in such wise that that line, extended, passes to one side

page_text: of said shaft; the result of this arrangement is that the time of movement of
the rack bar 39 (and the parts operated thereby) in one direction is greater than
its time of movement in the other direction. With the rack-bar 39 engaging
the top or upper side of pinion 38 on the side thereof towards the cylinder C and
the shaft 42 on the same side of the line of action of the rackbar 39 as the gear 38,
it follows that the return movement of the carriage 18 toward the cylinder C is
its slower movement while its outward movement is the faster; this arrangement
provides for the slow dropping or laying of the sheets upon the delivery-board 50
in an even or uniform pile. The crank 47 has one end of a pitman rod 51
pivotally connected therewith, and the other end of the rod 51 is similarly con-
nected at 52 with a lever 53 which is preferably pivoted to the framework A, as
at 54, on the same side of the line of motion of the rackbar 39 as the shaft 42.
The lever 53 is connected to the rack 39 by a pitman-rod 55 which is pivotally
connected to the lever at 56 and to the rack at 57. The crank 47 moves to the
left in Figure 33, see arrow a, and the lever 53 continues to move downwardly
until the crank 47 reaches the position indicated by the dotted line b, which is
more than a half-revolution of the crank from the position shown in full line or
that position of the parts in which the centers of shaft 42, crank 47, and
pivot 53 are in line in the order named. As shown by the dotted line c, the pivot
or hinge 52 reaches the limit of its motion downwards when the centers of
crank 47, shaft 42, and pivot 53 are in line in the order named (in which case,
the rod 51 lies across the disk 48), at which time the carriage 18 is nearest the
cylinder C.
The sheet-support shown in these figures (33 to 39) of the drawings consists
of a web or ribbands of fabric 58 having one end thereof fast to a bar 59 which
is secured to the frame B closely adjacent to the pulleys 7 in such relation thereto
that the sheets, when run out by the tapes 5, are run upon the top of the fabric 58;
the other end of the fabric 58 is fast to a hollow roller 60 which is loose on the
shaft 29 aforesaid, and the fabric is wound on and unwound from said roller 60
during the excursions of the carriage 18 toward and from the cylinder C. The
bar 23 is provided with an extension 61 at its top whose edge is very nearly in
contact with the fabric 58 when the latter is rolled up on the roller 60, thus
ensuring that the heads of the sheets shall run upon the top of the bar or gripping-
member 23 as they are delivered thereto by the tapes 5. The fabric 58 is wound
upon the roller 60 by means of a tape 62 which is fast at one end to the roller 60
and at its other end to a roller 63 journalled at 64 in an arm from the frame B.
This roller 63 may be loose upon the shaft or stud 64 and be connected thereto
or to the frame B by means of a spiral spring coiled around the shaft and having
one end fast to the shaft or frame B and the other end fast to the roller 63, thus
providing for the automatic taking up of any slack in the fabric 58 during the
operation of the mechanism. The tape 62 winds on the roller GO at one edge of
the fabric 58 as the fabric winds off the roller 60 and unwinds therefrom as the
fabric winds up on the roller 60. Or I may use two such tapes 62 and rollers 63,
one set being at one edge of the fabric 58 and the other set being at the other
edge of said fabric.
The sheet-gripping mechanism herein shown includes the bar 23 and a set of
grippers 65 each gripper being provided with a gripping or working-face 66 for
coaction with the top 25 of the bar 23 and each gripper being, by preference,
provided with a stop 67 preferably at right angles thereto for the sheets, and said
stops preferably being integral with the grippers 65. The sheet-stops 67 are
shown as arranged to drop in front of the bar 23, and they may or may not touch
the same.
The grippers 65 are fast on and move with a shaft 68 which is
journalled in arms 69 extending downwardly on the cylinder side of the shaft 22
from the same. The shaft 68 has an arm 70 fast thereto, which arm is preferably
provided with a side-lug or projection 71 and with a roller 72 at one side thereof,
by means of which the armi 70 and shaft 6S are operated. The hub 73 of the
arm 70 has a second arm 74 projecting therefrom, and the end-piece 20 is provided

page_text: with a lug 75; a rod 76 is pivotally connected with the end of arm 74 at 77 and
passes loosely through a perforation in the lug 75; a spring 78, coiled about the
rod 76, bears, at its ends, against the lug 75 and a collar or other stop of the rod.
The rod 76, lug 75, and shaft 68 are so arranged relatively to each other that the
force of the expansive spring 78 tends to rotate the shaft in either direction,
according as the center 77 is above or below the line joining the centers of lug 75
and shaft 68. The rotation of the shaft CS in one direction is limited by the
faces 66 of the grippers 65 coming in contact with the top 25 of the bar 23 and
in the other direction by a suitable stop (not shown).
Mechanism for rotating the shaft 68 so as to bring the center 77 above and
below the line joining the centers of shaft 68 and lug 75 will now be described.
The frame B is provided with a lug or standard 79 on one side and at the end
next the cylinder C. This lug 79 extends into the path of the arm 71 and may be
employed to operate the arm 70 and shaft 68, but I prefer to operate said arm and
shaft by an adjustable stop, as by a screw-bolt 80, which engages with a threaded
perforation or hole in the lug 79 and is provided with a jam-nut, as 81. The
head of the bolt 80 is in the path of the lug 71 and serves, in conjunction with
said lug, to push the center 77 below the center line joining the lug and shaft 69.
To prevent undue shock and noise, I provide the frame B with a stop 82 with
which the roller 72 comes in contact and by which the roller 72 and arm 70 are
stopped at the moment when the center 77 has passed the center line joining the
shaft 68 and lug 75 in its downward movement (see dotted lines d in Figure 35),
and this stop curves downwardly to allow the spring 78 to move the grippers 65
downwardly toward the bar 23 (see position e, Figure 35), but the working face
of the stop 82 becomes parallel with the line of motion of the carriage 18 at such
point, as 83, as will prevent the grippers 65 or their working faces 66 from grip-
ping the heads of the sheets against the top of bar 23, but will leave a small
space, as the 32d or 16th of an inch, between said top and said working-faces 66
into which the heads of the sheets are run (see position marked f, Figure 35) in
this last position of the faces 66 relatively to the top of the bar 23, the sheet-
stops 67 on the grippers extend in front of the head of the sheet and stop the
same at or in a predetermined position relatively to the front edge of the bar 23;
or rather, the speed of the sheets and of the carriage 18 are brought into unison
by the stops. The stop 82 ends at a point 84 and there the roller 72 drops off
the delaying-guide or stop 82, and the grippers close and grip the sheet firmly
against the bar 23. It will thus be seen that one function of the stop 82 is to
delay the closing of the grippers 65 until such time as the heads of the sheets
are in proper or desired relation with respect to the stops 67. The grippers re-
main closed and draw the sheets along over the support 58 until the carriage 18
reaches the end of its outward movenient, when the roller 72 is acted upon by a
cam or lifter to rock the shaft GS to bring center 77 above the line joining the
centers of shaft 68 and lug 75, thus opening the grippers and moving the stops
out of the way of the sheets. I prefer to have the lifter for the arm 70 a movable
one, so as to quickly open the grippers and release the sheets at the instant the
carriage 18 ceases or ends its movement. I therefore show a lifting arm 85 which
is fast to shaft 86 journalled in the frame Bor in suitable bearings 87 88 attached
thereto. This shaft 86 is provided with an arm 89 with which one end of a pit-
man-rod 90 is pivotally connected, the other end of the rod being similarly con-
nected with one end of a lever 91, which is pivoted at 92 to the frame A or to a
bracket thereon. The other end of the lever 91 is provided with an anti-friction
roller 93 which is in position to be acted on by a cam 94 on the aforesaid disk 48
to lift that end of lever 91, and, through the described connections, to lift the
arm 85 at the moment carriage 18 reaches the limit of its outward movement and
is at rest, and thus to release the sheets as aforesaid.
In some cases, when the sheets used are of a sufficient thickness or stiffness,
the grippers 65 may be formed to engage the bar 23 at an angle instead of flat-
wise, thus providing acute openings into which the heads of the sheets are run and

page_text: jammed or held by the grippers and bar, thus avoiding the necessity for the second
drop-motion of the grippers to close them.
The stop 82 is preferably detachable from and adjustable along the top of the
frame B, as by slots 95 in the stop and the headed screw-bolts 96 which pass
through the said slots and engage with threaded holes in the frame B. Washers 97
under the bolt-heads may be used, if desired.
In order to capacitate the press for the production of copies of various sizes
or widths, and to adjust the tapes 11 so as to coact only with the margins of sheets
of various widths, provide means whereby the pulleys 12 13 may be readily and
accurately adjusted along their respective shafts. The novel means employed
for this purpose are shown in Figures 38 and 39 and will now be described. The
shafts 14 15 are shown as being round in cross-section, and are shown as being
provided with two or more grooves 98 which extend circumferentially thereof.
These grooves are preferably circular or rather semi-circular in cross-section, and
are at distances apart such that various regular widths of papers used for printing
upon correspond thereto. I may provide two or more of these grooves for each
pair of pulleys 12 13, or I may provide them for only one pair of such pulleys 12
13, or I may provide them on but one shaft and pulleys on that shaft and employ
a roller instead of pulleys on the other shaft for the tapes 11. The pulleys 12 13
which it is desired to adjust are each provided with internal grooves in their
hubs, such grooves being marked 99 in the drawings, and being sufficiently deep
to wholly receive the (round) wire springs 101 when these are forced outward
thereinto. The springs 101 normally tend to close into the grooves 98 and pro-
ject into the grooves 99 in the hubs 100, being of a diameter substantially equal
to the diameter of the grooves 98. The pulleys are connected with their shafts
by spline 102 and corresponding groove; the spline may be on either part and the
groove on the other part, as will be understood; the pulleys are thus held against
rotation independent of their shafts. When it is desired to adjust the pulleys
and their tapes along their shafts, the pulleys are pushed endwise of their shafts
with force sufficient to cause the springs 101 to expand and jump out of grooves 98
into the grooves 99 and onto the outer surface of their shafts, whereupon the
springs and pulleys may be slid along the shafts to the next groove, where the
springs snap into the groove 98 and bring the pulleys to a stop; in this way,
the pulleys may be adjusted along the shafts from one to another of said grooves,
and carry their tapes along with them. In case a roller be used for the tapes and
the said adjustable pulleys be used for them at the other end, the adjustment of
the pulleys in the described manner causes the tapes to slide along the roller to
the new position for the tapes. It will thus be seen that this feature of my inven-
tion includes a grooved or notched shaft, a recessed pulley or wheel, and a spring
detent for connecting wheel and shaft through the medium of the grooves or
notches and recess.
The operation of the above-described delivery-mechanism will now be described.
The positions of the parts shown in Fig. 33 are those occurring in a two-revolu-
tion-cylinder printing-press at the end of the first revolution of the cylinder C,
as during a forward or printing-stroke of the bed; the carriage 18 has just
reached the limit of its outward movement and the grippers 65 have just been
opened. As the cylinder C moves from the position shown and as its grippers 2
approach the guides, they are opened by suitable means and the sheet upon the
cylinder is directed upon the guides 3 and by the guides 3 to the tapes 5. The
returning carriage 18 delivers the sheet thereon as hereinafter set forth. The
sheet from cylinder C is run out by tapes 5 and between pulleys 7 and 13 and
onto the fabric 58. During the second revolution of the cylinder C and while the
tapes are carrying the sheet out, the carriage 18 is returning to the left in
Figure 33 or toward the impression-cylinder C by the described mechanism. As
the carriage 18 reaches the end of its return movement, the arm or lug 71 comes
in contact with and is moved by the fixed abutment 80, and the arm 70, shaft 68,

page_text: and grippers 65 are moved into the position indicated in dotted lines at the left
of Figure 35, in which position the center 77 is just below the line joining the
centers 68 and 75, and in which the action of spring 78 tends to close the grip-
pers (5 on the bar 23. The grippers 65 are prevented from closing down on the
bar 23 at this time, however, by the delaying-stop 82 with which the roller 72
comes in contact and by which the roller and arm are arrested as indicated in
Fig. 35 (position marked d). As the carriage 18 reverses its motion and moves
away from the impression-cylinder C and the position d, the roller 72 rolls off
or down the inclined top e of stop 82 onto the portion of the stop which is parallel
with the path or line of movement of the carriage 18; at this time, the grippers 65
are very close above the top of bar 23, say the 32d of an inch therefrom, and the
stops 67 are in position in front of the bar 23 to stop the sheet as it is run out
(see position marked f in Figure 35). By the time the roller reaches the point 84,
the sheet has overtaken the stops 67 and is stopped thereby or rather the sheet
and stops are now moving at the same speed, and the grippers close down on the
sheet and firmly grip it against the bar 23, since the roller 72 is now freed from
control and the spring 78 can operate to close the grippers. During the further
outward motion of carriage 18, the sheet is drawn out from between the tapes 5
and 11 by the said gripping-mechanism and is drawn over the unrolling sup-
port 58.
As the carriage 18 reaches the limit of its outward movement, the
cam 94 operates the lever 91, and through the described connections the shaft 86
is rocked and causes arm 85 to lift roller 72 and thus to rock the arm 70 and
shaft 68 until the center 77 passes above the lines of centers 68 and 75, whereupon
the spring 78 completes the motion of the parts and moves the grippers 65,
arm 70, etc. into the positions shown in Figure 37. By preference, this opening
of the grippers and release of the sheets occurs at the moment the carriage 18
comes to rest at the end of its outward movement, of course the parts may be so
adjusted or timed as to cause the release of the sheets just before or just after
this particular moment or position. During the relatively slower return of the
carriage toward the cylinder C, the roller 60 winds up the support 58 and the
sheet falls head first on to the board 50 and against the pivoted spring-pressed
stops 102.
While I have shown an extensible-collapsible sheet-support operated by certain
means, I do not limit myself in this part of my invention to such support or to
such means,
for, in so far as certain features of my invention are concerned, other
forms of support and other operating means may be used without departing from
my invention.
Referring now to Figures 25 to 32.

In all the views the same parts will be found marked with the same letter or
numeral of reference.
The two-revolution stop-impression-cylinder C does not drive the tapes 11, 12
sufficiently far before it stops to run full-sized sheets beyond the rollers or
pulleys 13 and 17 or so far that the nip of the tapes 11, 12 on the sheets will be

page_text: freed when the rollers 14 and 18 are separated as herein before stated; there is thus a
liability that the sheets may be torn as they are drawn from between these
rollers 13 and 17 or tapes 11 12 during the delivery; this chance becomes the more
probable in case the sheets are to be split or severed as they are run out between
tapes 11-12 as by the rotatory knife or splitter 41 on the shaft 19 and the co-
acting grooved roller 42 on the shaft 15. This difficulty is met by means of a
supplemental driving-mechanism for continuing the forward or delivery rotation
of shafts 15 and 19 and the motion of the tapes 11-12 until the sheets are moved
so far that the danger of tearing them as they are drawn from between the
tapes 11 12 is entirely obviated.
The shafts of the tape-carrying pulleys 19 13 are provided with pinions 30
and 31 (see Fig. 28b) which mesh with each other, and the latter pinion meshes
with a pinion 32 journalled in the frame A, and this last pinion meshes with a
pinion 33 on the cylinder C. The pinion 30 is fast on its shaft, while pinion 31
is loose on its shaft and is connected thereto to drive the shaft in one direction
only by any suitable form of clutch as 34, Fig. 28, all for a reason presently to
appear. A convenient form of one-way clutch for this purpose is shown in
Figs. 29, 30, 31 and 32 wherein a disk 35 is fast to the shaft 15 and is provided
with a rim or flange 36, and the pinion 31 is fast to the hub 37 of a disk 38 which
is loose on shaft 15 in so far as rotational motion is concerned; one or more
friction pawls 39 are pivoted to the disk 38 at 40 and have their ends bearing
against the inner surface of rim 36, and are held to their work by springs 71.
The driving mechanism shown in Figs. 28, 28 and 28 for this purpose includes
a reciprocating rack-bar 43, suitably guided on the frame A, a pinion 44, loose
on the shaft 15, a clutch, as 34, for connecting the pinion 44 with the shaft 15
to drive it in the direction in which the same is driven from the cylinder C, and
means for operating the rack bar 43 from a cam 45 on the main driving or other
shaft 46 of the machine, such as a lever 47 pivoted at 48 to framing A, an anti-
friction roller or stud 49 on said lever and engaging the cam 45, a link or
pitman 50 pivotally connected to the lever 47 and to a bell-crank-lever 51
pivoted to the frame A at 52, and a link or pitman 53 pivotally connected with
the lever 51 and the bar 43.
The preferred form of the clutch 34" above referred to is illustrated in Figs. 25
and 26, in which the shaft 15 is reduced in diameter at one end and is there
bored out longitudinally at 54 to receive the round slide or shaft 55. A sleeve 56 is
fixed to the reduced end of shaft 15 to turn therewith and to slide thereon, as by
a feather or spline 57, and is connected to slide 55 by a bolt or pin 58 which
passes through the longitudinal slots 59 in the hollow end of shaft 15, whereby
slide 55 and collar or sleeve 56 may slide lengthwise of shaft 15 but are compelled
to turn with that shaft. In the normal positions of the parts, the sleeve 56 is
separated from the shoulder on the shaft 15 by a small space or interval 60 to
allow of the said lengthwise motion; this is because of the relative positions of
the pinion 44 and the sleeve 56 on the shaft 15. If their positions were inverted,
such space 60 would be between these two parts or parts connected with them.
A second sleeve 61 is splined to shaft 15 to have motion endwise thereof while
being incapable of independent rotational motion, and said second sleeve abuts
against the sleeve 56. The loose pinion 44 is fast to a disk 62 which is also loose
on shaft 15 and is provided with a rim or flange 63. Within the rim 63 are a
number (say three) of segments 04 whose exterior surfaces are formed on arcs
having radii equal to the radius of the internal surface of the rim 63 and are
adapted to bear frictionally against such internal surface. These segments are
held in place by a spider 65 which is splined to the shaft 15 to be capable of
motion endwise thereof and to rotate therewith, as by the spline 57, and is or may
be made of resilient metal somewhat dished or concaved on that side next the
disk 62. The ends of the legs of the spider 65 rest in suitable slots at the ends of
the segments 64 and allow said segments to move in and out radially of the clutch
to connect and disconnect the shaft 15 and the pinion 44. The parts are so

page_text: arranged that the elastic spider normally forces the sleeves 56 and 61 away from
the disk 62 and toward the frame A. The sleeve 61 is provided with suitable slots
and seats for the ends of three pushers 66 whose other ends rest in slots in the
segments 64. The pushers 66 are arranged obliquely as regards the shaft 15, so
.that the endwise movements of the sleeve 61 will cause them to push the seg-
ments 64 out against the rim 63, and permit them to fall away
therefrom. The pinion 44 and disk 62 are prevented from moving
endwise of the shaft 15 by any suitable means, as by a collar or the like on the
shaft (not shown). For the purpose of operating the clutch at the proper times
to cause it to connect the pinion 44 to the shaft 15 to the latter, I provide a
lever 67, pivoted at 68 to frame A, and operate it by means of a cam 69 on the said
shaft 29, an anti-friction roller 70 being interposed between the lever and the
cam; the force exerted by the spider 65 acting through the sleeves 61 and 56,
pin 58, shaft 55, and lever 67, serves to keep the stud or roller 70 against the
cam 69. It is noted that in Figs. 25 and 26, the pinion 44 and lever 67 are at
one end of the shaft 15, while in Fig. 28, these parts are at opposite ends of the
said shaft 15, and that the shaft 15 is hollow from end to end in the latter case and
the shaft 55 practically extends from end to end of the shaft 15. The operation in
each case is substantially the same.
In lieu of the clutch just described, the form of clutch shown in Figs. 29 and 30
may be employed for connecting and disconnecting the pinion 44 and the shaft 15,
and in this case, the lever 67, slide 55, and sleeves 56 and 61 are dispensed
with.
The sheets are preferably fed by hand from the feed board 1 against the
gauges 2 and over the lifting fingers 5 and under the upraised ends of the guides 6
and under the open grippers 4, after which the grippers are closed and the gauges
are lifted out of the way. During the forward or printing strokes of the bed, the
cylinder it first started up by the starting mechanism after which it is preferably
driven from the bed. During this stroke of the bed, the grippers 4 retain their
hold on the sheet until they approach the guides 10 the second time, when they
open and the fingers 5 lift the head of the sheet onto the said guides 10 by which
the sheet is guided to and between the carrying or delivery tapes 11 and 12.
The guides 10 are borne by the main frame A. The set of tapes 11 runs on pulleys
or rollers 13, 14, the pulleys 13 being on a shaft 15 and the pulleys 14 on a
shaft 16; the shaft 15 is journalled in the frame A near the cylinder C, and the
shaft 16 is journalled in the frame A nearer the delivery end of the machine.
The set of tapes 12 runs on pulleys or rollers 17, 18, the former being borne by a
shaft 19 journalled in the frame A above and near the shaft 15, and the latter
being journalled on a shaft or rod 20 which connects arms or levers 21 at opposite
sides of the machine; or the pulleys 18 may be fast on the shaft 20 which in that
case must be journalled in the arms 21. The arms 21 are pivoted to brackets 22
secured to the frame A. The levers 21 are pivoted at points intermediate to their
ends and are inclined or oblique with respect to the direction of motion of the
tapes 11, 12; the pulleys or roller 18 are at that end of the levers farthest
removed from the impression cylinder and above the plane in which the sheets
are fed forward. The other ends of levers 21 are below the said plane and are
joined by a rod or shaft on which the roller 23 is journalled, the said roller 23
being within the set of tapes 11.
It is obvious that, by rocking the frame formed by the arms 21, shaft or rod
forming the pivot or journal therefor, and the rods or shafts on which the
rollers 18 and 23 are journalled, the sets of tapes 11 12 may be separated and
brought together at that end of their paths; in this way, these tapes may be
caused to coact to feed forward the sheets and be opened to release them as desired
and this is done automatically in practice by means of the pitman rod 24 which
is pivotally connected at its ends with one of the levers 21 and an arm 25 of the
rock-shaft 26 journalled in the framework or in a bracket thereon. The shaft 26
is provided with a second arm 27 which is operatively connected with a cam 28

page_text: and a side-shaft 29 of the machine, as by an anti-friction roller (not shown). A
spring (not shown) may keep the arm 27 or its roller in contact with the cam 28;
or the cam may be a grooved or face-cam and the arm 27 or its roller engage
therewith; both constructions are well-known, and either may be used. The
shaft 29 preferably makes one complete turn to one complete to and fro movement
of the bed.
The operation of the foregoing devices is as follows: With the parts in the
positions shown in Fig. 28", the bed (not shown) is at the extreme right hand end
of its movement and moves to the left in said figure. As the bed begins its printing
movement, the grippers 4 have been closed, and the gauges 2 have been lifted and
the cylinder starting mechanism begins to move the cylinder C simultaneously
with the bed-movement. The parts are so timed that the sheet held by the
grippers 4 is brought in proper register with the form on the bed and the
impression is given. As the grippers again approach the guides 10, they are
opened and the fingers 5 are lifted to cause the head of the sheet to pass upon the
guides 10 and to the tapes 11 and 12. As or before the sheet reaches the
tapes 11 12, the cam 28 causes or permits the levers or arms 21, through the
described mechanism to raise the roller 23 and lower the roller 18, thus bringing
the tapes 11 12 into such relation to each other that they will grip the sheet
firmly between them and feed it forward to the bar 83 and grippers 106. The
carriage D is moved to the left in Fig. 28", during the printing stroke of the
bed, reaching the extreme of its motion in time to receive the sheet as it passes
from between the rollers 14 and 18 as before described. As the cylinder C
completes its second turn, the stopping mechanism comes into action and brings
it to rest with the impression surface 128 in the position shown in Fig. 28*.
During the rotation of the cylinder C, the shaft 15 is driven therefrom through
the medium of the gears 33 32 31 and clutch 34; the gears 31 and 30 cause the
tapes 11 12 to be driven in the proper manner and direction to feed the sheet
forward to the carriage D. The shaft 15 is caused to continue its forward motion
by means of the rack 43, gear 44 and clutch above referred to in time to prevent
any pull upon the sheets by the carriage D moving away from the position shown
in Figure 28" other than that necessary to cause them to move with that carriage;
that is to say, the sheets are fed forward by the pulleys 13 and 17 or the
tapes 11 12 until their tails have cleared the said pulleys; at the same time, the
levers 21 are rocked to lift roller 18 and to lower roller 23 to cause a separation
of the tapes at that end to free the sheet wholly from the tapes 11 12 and
permit the grippers to draw the sheets from off the tapes 11 as the carriage D
moves away from the impression cylinder C. It is understood, of course, that
the lever 67 is operated at the proper time to close the clutch shown in Figs. 25
and 26, in case that form of clutch is used. During the time the rack 43 and
gear 44 are driving the shaft 15, the clutch 34 slips freely and does not impede
the action.
Figure 40 is a side elevation showing a modified form of the mechanism for
driving the inking-devices independently of the form and ink-table on the bed,
another form of such mechanism being shown in Figures 2 and 3.

In Figure 40 as in Figure 2, the reference C marks the impression cylinder;:
B the reciprocating bed; 3 the ink-table; and 4 a form on the bed.
5 marks

page_text: a rack on the bed B, which rack is of a length sufficient to maintain mesh with
the gears 6 and 7, which are journalled on the frame A, in all positions of the
rack and bed. The pinions 7 mesh with pinions 8 on the shafts of distributing-
rolls 9. The rolls coact with form-rolis 10 and drive the same independently
of the form 4, though, of course, the rolls 10 are driven by both the form and
roll 9 at times. 11 indicates additional distributing-rolls coacting with the
rolls 9.
The pinion 6 is considerably wider than the rack 5 and meshes with a
pinion 12, journalled on a bracket or riser on the frame A; intermediate gears 13
connect pinion 12 with a pinion 14, and pinion 14 is connected with a pinion 15
through an intermediate pinion 16. Pinions 14 and 15 mesh with pinions fast on
the shafts, of metal, as steel, distributing-rolls 17 and 18 respectively and drive
the said pinions and rolls. Composition distributing-rolls 19 are in surface con-
tact with rolls 17 and 18, and are driven thereby. Rolls 19, but not rolls 17
and 18, are in position to coact with the ink-table 3 as the same moves to and fro
under them. A steel transfer roll 20 lies in surface contact with two of the
rolls 19. It will now be seen that rolls 17, 18, 19, 20 are oscillated during the
to and fro motion of bed B, being continuously driven by rack 5 and the
described connections; this is very advantageous, leading, as it does, to a better
and more uniform distribution of the ink than is the case when the form and dis-
tributing rolls are driven only by the ink-table and the form.
The ink is transferred from a fountain 21 to roller 18 in the following manner:
A fountain-roller 22 transfers ink to a ductor-roll 23, and roll 23 transfers the
ink to roll 18, the rolls 22, 23 being operated as will now be described. The shaft
of roll 22 is journalled at end in any suitable way in the end of the fountain 21
and one end of said shaft is extended beyond the fountain-end and is provided
with a ratchet-wheel 24 fast thereto. That face of wheel 24 at the end of said
shaft is provided with two (or more) diametrically opposite projections, as
pins 25, inserted and fast in holes in wheel 24 which are positively beveled, the
planes or faces of said bevels being transverse of the face of the ratchet-wheel.
A shaft 20 is journalled in a sleeve 27 to have an endwise movement and to
have its axis in line with the axis of the roll 22, and its end adjacent to the
ratchet-wheel 24 is provided with a rectangular cross-bar 28 fast thereto. The
bar 28 has one longitudinal outer edge beveled off at each end, the bevels being
at opposite sides of the bar, as indicated in Figure 44 by full and dotted lines,
and said bevels being adapted for coaction with the beveled ends of pins 25
to allow the head or bar 28 and ratchet 24 to slip by each other in one direction,
and the sides of bar 28 which are across the bar from its beveled edges being
square and adapted to coact with the sides of pins 25 opposite the bevels thereon
to cause the shaft 26, wheel 24 and roll 22 to turn together. The sleeve 27 is
journalled in frame A or an attachment thereto and is held against endwise
motion by a disk or plate 29 at one end of the sleeve, by a toothed or serrated
disk 30 secured to said sleeve at its other end, and a plate 31 loose on the sleeve
between frame A and disk 30, the disk 29 being adjacent to or adjoining the
ratchet-wheel 24 and provided with teeth 32 on a part of the circumference
thereof. The disk 29 is bored out axially thereof to receive the bar 28 and
pins 25 therein, the bore being of such depth that shaft 26 may move endwise
sufficiently far to wholly remove bar 28 from the path of pins 25 as the shaft
or roll 22 is rotated. The shaft 26 is provided with an arm and handle 33
fast, thereto and so placed thereon as to permit of the endwise movement of
shaft 26 requisite to cause bar 28 to engage pins 25. The plate 31 has its peri-
phery formed on arcs of unequal radii, the arc of greater radius being adapted to
act as a stop for the ductor-roll 23, as will presently be described. The plate 31
can be adjusted to and held in any position relative to the serrated wheel 30 by
means of a spring-pressed pointed plunger 34 which is held in a tubular guido
secured to the plate 31 and which engages with the serrated wheel 30 and so
holds plate or stop 31 in adjusted position. The sleeve 27 is connected with the

page_text: ratchet-wheel 24 by means of a pawl 35 which is pivoted to an arm of disk 29
and engages with the teeth of the wheel 24, whence it results that an oscillatory
motion of sleeve 27 gives an intermittent progressive motion to the roller 22.
Devices for operating sleeve 27 will now be described. A toothed or rack-
segment 36 is carried by a lever 37 pivoted at a point intermediate its ends, the
lever 37 shown comprising a rock shaft and two oppositely projecting arms
thereon one of which carries rack 36. To the other of said arms, one end of a
connecting rod or link 38 is pivoted. At its other end the link 38 is similarly
connected to a rock-arm 39 which is moved to and fro by a rotatory cam 40 on
a transverse shaft of the machine. The motion of cam 40 thus serves, through
the described connections, to oscillate the sleeve 27 and so to intermittently and
progressively rotate the fountain roll 22.
2
In order to secure that the ductor roll shall come in contact with the fountain
roll at a time when both are at rest, or, rather, are not rotating, I provide
brake-mechanism for stopping any rotatory motion of roll 23 before it comes in
contact with roll 22, and the preferred form of such mechanism will now be
described. The roller 23 is journalled in the forked ends of arms 41 (but one
arm 41 is shown) fast on a journalled shaft 42 extending across the machine below
the path of table 3. One arm 41 (or both) is provided with a slide 43, guided
lengthwise of said arm and slotted to embrace the boss of said arm, and provided
at one end with a brake-shoe 44 adapted to coact with the shaft of roll 23. The
brake-slide 43 is moved endwise in one direction, when the ductor-roll is moved
to and from the fountain-roll, by means of cam 45 on an arm 46 of the main
frame, and its weight moves it in the reverse direction. The shaft 42 is pro-
vided with an arm 47 by means of which it is rocked and with an arm 48. An
adjustable (screw-threaded) stop 49 on arm 48 is adapted to coact with the cam-
plate 31 to stop roll 23 before it reaches roll 22 and hold it out of contact there-
with until plate 31 has been turned with sleeve 27 far enough to move the arc
or surface of greater radius from under stop 49, whereupon the stop is freed and
roller 23 moves into contact with fountain-roller 22. By varying the position of
plate 31, by means of pin 34 and wheel 30, relatively to the sleeve 27, the time
the ductor roller is so held out of contact with the roll 22 may be varied, and
thus the amount of ink taken by roller 23 may be varied.
The ductor-roller 23 is moved between the roll 18 and roll 22 by means of a
rod 50, rocker-arm 51, and cam 52, the said rod being pivotally connected with
arms 47 and 51. The cam 52 is widened out in that position thereof in connec-
tion with arm 51 when the ductor-roll 23 is stopped by plate 31 and in contact
with the fountain-roll 22 in order to allow free motion of the ductor roll at such
times.
The operation of the foregoing devices has been partly given herein before, and
may be sufficiently obvious to those acquainted with the art, but additional
description of the operation follows.
The fountain-roll 22 is turned an invariable distance at each forward or operat-
ing swing of segment 36, but the time during which the ductor-roll 23 is in con-
tact therewith is variable or regulatable as for the purposes above set forth. The
mechanism for operating the ductor-roll is so timed that the roll is lifted to pass
above and preferably in contact with the table 3, as the bed moves to the right
in Figure 40 (and in Figure 2), and is brought into contact with the right hand
roller 18 (rollers 17 and 18 are identical with the rollers 118 of Figure 2) to
transfer ink thereto. In the to and fro movements of the ductor roller 23, the
brake-mechanism is applied as hereinbefore described, so that the roller 23 is
brought into contact with roller 22 when roller 23 is at rest. The brake-
mechanism is actuated, of course, as roller 23 is swung toward and into contact
with roller 18 while roller 18 is at rest or reversing and hence both rollers begin
to move together.
Referring again to Figure 1 (Sheet 1):
The reference letter a marks a feed-board from which the sheets are fed to the

page_text: impression-cylinder C, the said board being suitably supported on the frame-
work A, as indicated by the dotted lines. The sheets, after being printed upon,
are run from cylinder Cupon a set of tapes b, as by guides similar to the guides 4
shown in Figure 12 (Sheet 6), the tapes being carried by rollers or pulleys c
which are suitably journalled in the framework of the machine. A set of tapes d,
lying over tapes b, aid in holding the sheets as they are fed forward to a suitable
delivery-mechanism to be delivered thereby upon the delivery-board e; any
suitable form of delivery mechanism may be used for laying the sheets with their
freshly printed sides uppermost on the board e. For the purpose of automatically
placing "slip" sheets between the sheets coming from cylinder C, I show a
mechanism in this figure (Figure 1, Sheet 1) comprising a feed-board f, a cylin-
der g, grippers h, and driving-mechanism for the cylinder. The particular
mechanism shown for driving the cylinder g comprises bevel-gears i connecting
the cylinder with a vertical side-shaft which may be driven in any desired
manner, as by a transverse shaft connected therewith by bevel-gearing 1. In
the operation of this form of the slip-sheet inserting mechanism, the sheets are
fed to the grippers from board f by hand, (or suitable guages and drop-rollers
may be used if desired,) and the cylinder y and its grippers carry them around
and drop or lay them on the sheets coming from cylinder C, the grippers / open-
ing for the purpose at the proper moment. The two sheets are subsequently
dropped together upon the board e. In case the sheet-carrier for carrying the
sheets out over board e is driven from cylinder g (in which case that cylinder
and its driving mechanism would have to oscillate), as by pinion m and rack n,
the frame o, which supports boards e and f and the delivery, would have an
extension or guide p for the rack or other parts.
h
Referring again to Figure 2 (Sheet 1): The form-rolls g and transfer-rolls r
are substantially identical with the rolls shown at 10 and 9 in Figure 40, and
are driven from the gearing 119. In case the machine is to be used for litho-
graphic printing a water fountain, fountain rolls, ductor-roll t, and distributing
rolls are to be added in order to dampen the form after each impression, the
ink-rolls u being raised by any suitable means as the bed moves to the left in
Figure 2, and being lowered in time to coact with the form on the return stroke
of the bed.
Referring to Figure 3 (Sheet 2) the reference indicates a slot in the web of
gear 19, said slot extending perpendicularly to the line joining the centers of
motion of bearer 29 and a bearer 31 coacting with ring-bearer 28; w marks a
slide movable endwise of said slot; a marks screws which engage threaded holes
in a flange y at the ends of said slot and bear at their ends against the said
slide w, the purpose being to adjust the intermediate bearer 31 (whose axle 31
is carried by said slide) to provide for taking up any looseness due to wear of
parts.
I remark that, while claims 1 to 35 inclusive are framed more particularly
upon the construction illustrated in Figs. 1 to 7 inclusive, claims 36 to 37 inclusive
upon the construction shown in Figs. 8 to 22 inclusive, claim 68 upon Figs. 23
and 24, claims 69 to 104 upon Figs. 25 to 32, and claims 105 to 134 upon the
construction shown in Figs. 33 to 39, I do not limit my claims to the specific
forms or devices shown and herein before described inasmuch as my invention
may be embodied in many forms without departing from the substance thereof.
I also remark that, instead of driving tapes II 12 from cylinders C (see
Figure 28), the said tapes may be driven from some other part reciprocating
with the type-bed or oscillating with an oscillatory cylinder or even stopping
during a part of the time, since the supplemental mechanism for continuing the
forward or progressive motion of said tapes will still act in the manner set forth
herein before.
I also remark that the parts shown in Figure 40 are so timed that the ductor
roll comes into contact with the roll 18 at the moment roll 18 is reversing or is
stationary, and that the ductor roll is raised above the table 3 just before the

page_text: table passes over the fountain; also, that the ductor-roll comes in contact with
the fountain roll when the last is moving slowly or just coming to rest, in each
case, the composition roll is preserved from injury.

provided with gripper-members one of which is constructed to be moved into and
out of position for coaction with the other member and to be spring-held in
such positions, a rock-shaft adjacent the path of said carrier and provided with
an arm, and a bent-arm connected to said movable gripper-member and actuated
by said rock-shaft arm to move said gripper-member from one to another of its
said positions, with means for rocking or moving said movable-member in the
contrary direction when the carrier is at or near the other end of its motion,
substantially as described.
164. In a sheet-delivery, the combination of a to and fro moving sheet-carrier,
a relatively fixed and a movable gripper-member moving with said carrier,

page_text: spring-mechanism for holding said movable member against and away from the
said fixed member, an actuating-arm connected with said movable member, a
rock-shaft on the fixed framework, and an arm on said shaft for operating said
actuating-arm and movable member when the carrier is near one end of its
motion or path to move the member from one to its other position, with
means for coaction with said actuating-arm to move the same and said member
from the position to which said shaft moved them to their other position,
whereby sheets are released and gripped, substantially as hereinbefore described.
165. In a sheet-delivery, the combination of a to and fro moving sheet-carrier,
fixed gripper bar or grippers moving with said carrier, a shaft also moving with
said carrier, a set of grippers on said shaft, spring-mechanism for holding said
shaft in each of two positions or with its grippers coacting with said har or
grippers to hold sheets and away therefrom to release sheets, a bent arm on said
shaft, a side rock-shaft, and an arm thereon for coacting with said bent arm
to operate the same and the grippers controlled by said arm and said spring-
mechanism, whereby the grippers are moved from one to another of their gripping
and releasing positions, substantially as described.
166. In a sheet-delivery, the combination of a to and fro moving sheet-carrier
or support, relatively fixed and movable gripper-members moving with said
support, a spring-actuated rock-shaft for holding said movable gripper-member
against and away from the fixed member, a bent arm on said shaft, a rock-shaft
on the fixed framework of the machine, and an arm of the second named rock-
shaft for lifting said bent-arm to actuate the movable gripper-member to release
sheets, substantially as hereinbefore described.
