Improvements in Printing Presses.
I, JAMES YATE JOINSON, of 115, St. Vincent Street, Glasgow, Chartered Patent
Agent, (being a communication from abroad by the Aluminium Plate & Press
Company, a corporation organized and existing under the laws of the State of
West Virginia, doing business at Plainfield, County of Union, State of New
Jersey, and No. 87, Nassau Street, in the City, County and State of New York)
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 improvements in printing-presses particularly de-
signed to perfect rotary surface printing presses, such rotary surface presses
being of great importance at the present time in view of the remarkable results
attained in aluminographic printing, but also applicable either wholly or in
part, to other kinds of rotary printing presses.
This invention relates firstly, to an improved form inking mechanism, which
comprises a series of form inking rollers and ink distributor rollers journaled in
a suitable vertically movable frame mounted upon the press-frame above the
form-cylinder, the ink distributor-rollers being geared to their driving gear
through the medium of a series of intermediate gears which are carried upon a
frame or spider which is movable circumferentially to said driving gear, and
suitable operating mechanism for automatically and simultaneously raising the
vertically movable frame and shifting the circumferentially movable frame or
spider for the purpose of lifting the form inking rollers out of contact with the
form-cylinder and at the same time moving the intermediate gears circum-
ferentially to keep the distributor-rollers in mesh with their driving gear. The
object of this arrangement is to continuously revolve the form inking rollers and
distributor-rollers whether they are in operative or inoperative relation to the
form-cylinder so as to maintain the ink upon the rollers in proper worked-up
condition. The mechanism for operating the vertically movable frame and the
circumferentially movable frame or spider is preferably actuated through suitable
link mechanism connected with said parts and operated by a cam at one end of
the form-cylinder. More specifically, the operating mechanism comprises a pair
of rock-arms or levers centrally engaging two vertically movable stands or side-
frames in which the form-rollers and distributor-rollers are mounted, a pair of
sliding cam-bars also engaging the vertically movable side-frames and connected
with the rock-arms or levers, pin and slot connections between the sliding cam-
bars and the circumferentially movable frame or spider, two pairs of toggle links
or levers connecting the rock-arms or levers with a stationary rock-shaft, and a
rock-arm projecting from said rock-shaft and engaging a slotted reciprocating
link formed with oppositely extending connected slots having upwardly and down-
wardly engaging shoulders, said link being connected with an arm which is
actuated by the cam upon the form-cylinder, and a manual controlling device
adapted to shift the slotted link and cause either its upwardly engaging shoulder

page_text: or its downwardly engaging shoulder to engage the rock-arm and move the
inking mechanism into or out of operative relation to the form-cylinder.
This invention relates, secondly, to a novel arrangement of the form-cylinder
driving mechanism and inking-roller driving mechanism whereby the rotation
of the form-cylinder may be arrested without interfering with the continuous
operation of the inking-roller mechanism. To effect this result a clutch upon
the form-cylinder shaft is provided which couples the main driving gear and
distributor-roller operating gear to the shaft of the form-cylinder. The main
driving gear is operated by a smaller gear upon the main driving shaft by which
it is constantly rotated. The inking-drum and ink mixing rollers are geared
to the main driving gear and the ink distributor-rollers are geared through the
intermediate gears above referred to with the distributor-roller driving gear
which is keyed to and rotates with the main driving gear. By throwing out
the clutch, the form-cylinder will be stopped while the main driving gear and
distributor-roller driving gear will continue to operate to keep the inking
mechanism in operation.
This invention relates, thirdly, to improvements in the form dampening
devices. This part of the invention comprises the usual water-fountain and
water-drum in combination with a novel arrangement of the vibrating water-
ductor-roller and operating mechanism and a novel arrangement of the water-
form rollers and operating mechanism. The water-ductor-roller is mounted
upon a rock-arm extending from a rock-shaft which is operated by a conoidal
cam engaged by an operating rock-arm mounted upon the ductor-roller rock-
shaft and adjustable longitudinally upon the shaft, whereby the oscillation of
the water-ductor-roller may be regulated to suit the existing requirements. The
water-form-rollers are adjustably mounted upon the ends of shear-like levers,
which levers are connected by toggle-links operated by a bell-crank lever, one
arm of which engages a slotted operating link, the slot of which is formed with
an upwardly and downwardly engaging notch, the link being supported and
operated by a bell-crank lever actuated by a cam upon the form-cylinder.
Manually controlled mechanism is provided for throwing out of operation the
water-form rollers, said mechanism comprising preferably a pair of geared arms
which are respectively adapted to disengage the slotted operating link from the
toggle-operating bell-crank and move the toggle-operating bell-crank into in-
operative position so as to support the water-form-rollers out of contact with the
form cylinder.
This invention relates, fourthly, to means for automatically throwing the im-
pression-cylinder into and out of operative relation with the form-cylinder.
This part of the invention comprises a pair of eccentric bushings in which the
impression cylinder is journaled, toggle-links or levers connecting the eccentric
bearing-bushings with a stationary rock-shaft, a cam-operated reciprocating link
formed with oppositely extending connected slots having upwardly and down-
wardly engaging shoulders, a rock-arm upon a stationary rock-shaft working in
the double slot of said reciprocating link, and manually controlled devices adapted
to shift the reciprocating slotted link so as to throw the upwardly engaging
shoulder or the downwardly engaging shoulder into engagement with the
operating rock-arm for the purpose of straightening or breaking the toggle-links
or levers and thereby moving the impression-cylinder into or out of operative
relation with the form-cylinder. The manually controlled device for regulating
the automatic throw-out comprises preferably a rock-arm operated by a suitable
hand or foot lever and engaging one face of the reciprocating slotted link, a
spring-device holding said manually controlled rock-arm in engagement with
the slotted link and tending to move the link in one direction and a second
spring-device engaging the slotted link and tending to move it in the opposite
direction, the first named spring-device being the stronger of the two so as to
normally hold the reciprocating slotted link in position for moving the impression
cylinder into operative relation with the form cylinder, said stronger spring-

page_text: device being under the control of the manually operated lever so that when said
spring-pressed rock-arm is moved away from the reciprocating slotted link the
second spring-device will move said slotted link to its other position for breaking
the toggle links or levers and moving the impression cylinder into inoperative
position. The oppositely extending slots of the reciprocating link are for the
purpose of allowing the continuous reciprocation of the link during either
position of the toggle operating rock-arm, the rock-arm playing in one of the
slots when in one position and in the other slot when in the other position. The
reciprocating link is operated by a suitable cam upon the impression-cylinder.
This invention relates fifthly, to improved controlling devices for the several
parts of the press. A suitable brake and belt-shifter are geared to a controlling
device which may be operated separately or which may be operated in conjunction
with the impression-cylinder throw-out mechanism.
This invention relates, finally, to numerous features of construction ancillary
to the above-noted important features and in order that this invention may be
fully understood the same will first be described with reference to the accom-
panying drawings and the novelty will be afterwards pointed out in the claims
with more particularity.

The machine frame 1 may be of any suitable design to properly support the
hereinafter described operating parts of this improved printing press.
5 is a form-cylinder provided at its ends with bearing-gudgeons 6 which are
journaled in bearing-bushings 7 rigidly supported in the side-frames of the
machine. At the opposite ends of the form-cylinder 5 are secured the large
cog-gears 8 and 9. The form-cylinder is constructed as usual with a segmental
form supporting surface and a segmental ink-distributing surface separated by
cut-out portions which are shown but not specifically described, and is provided
with form clamps 4 of any suitable construction, adapted to engage a flexible
form, preferably an aluminium printing plate. The gudgeon or axle 6 at the gear-
side of the machine carries a splined sliding clutch-member 10 which is adapted
to engage the fixed clutch-member 11" formed upon the hub of the main driving
gear 11, which driving gear 11 is loosely journaled upon the extension of the
axle 6. The gear 11 is driven by a smaller gear 12 keyed to the main driving
shaft 13 which is provided with the usual fast and loose pulleys 14, 15 around
which the main driving band 16 operates. 17 is the distributor-rollers operating
gear of finer pitch than main driving gear 11 and located inside of main gear 11
and keyed to its hub so as to rotate and be driven with the main driving gear.
18 is the clutch operating lever journaled at 19 and engaging the movable
member 10 of the clutch.
20 is the impression-cylinder provided with suitable paper grips, not specifically
described. The impression-cylinder 20 is provided at its ends with large cog-
gears 21 and 22 which mesh with the cog-gears 8 and 9 of the form-cylinder,
The im-
whereby the impression-cylinder is driven from the form-cylinder.
pression cylinder 20 has bearing-gudgeons or axles 23 which are supported in
eccentric bearing-bushings 24 and 25 which are journaled in rigid bearings in
the side-frames of the machine and are automatically controlled by mechanism
hereinafter described for moving the impression-cylinder into or out of operative
relation with the form-cylinder, the movement to and from the form-cylinder
being so slight that the gears 21 and 22 always remain in mesh with gears 8
and 9.
26 is the inclined feed-board or table upon which the sheets are fed to suitable
sheet-guides which hold the successive sheets in position to be taken by the
sheet grippers of the impression-cylinder.
The form inking mechanism will now be described. At the forward end of
the machine the side-frames are built up above the form-cylinder to support the
form inking mechanism. 30 is the ink-fountain extending across the front of
the machine and supported between the upward extensions of the side-frames.
31 is the ink fountain-roller journaled in the ends of the ink-fountain. 32 is
the ductor-roller rock-shaft journaled in suitable bearings and supporting the
upwardly extending forked rock-arms 33 in the forked ends of which is journaled
the ductor-roller 34. 35 is a rock-arm keyed to the end of rock-shaft 32 and
carrying in its upper slotted and an adjustably-supported anti-friction roll 30

page_text: which operates in the groove-cam 37 formed in the face of the large gear-wheel 38
keyed to the end of the shaft 39 which is journaled in the upper extensions
of the side-frames and extends from side to side of the machine. 40 is the inking-
drum mounted upon shaft 41 which is journaled in the side-frames of the
machine and has splined to its projecting end at the gear-side of the machine,
a gear-wheel 42 which meshes with the intermediate gear 43 driven by the
main driving-gear 11. By the operation of cam 37 upon rock-arm 35 the ductor-
roller 34 is oscillated from the ink fountain-roll 31 to the inking-drum 40 for
conveying ink from the former to the latter. Keyed to the projecting end of
shaft 31" of the ink fountain-roll 31 at the gear side of the machine is a ratchet-
wheel 45 with which engages a gravity-pawl 46 journaled upon a pin 47" carried
by a rock-arm 47 which is keyed to a short shaft 48 journaled in the press-frame
in line with shaft 31". 49 is another rock-arm keyed upon shaft 48 and connected
thereby with the rock-arm 47. The upper end of rock-arm 49 carries a pin 49"
which engages elongated slot 50 formed in the forward free end of a pitman 51
journaled upon a crank-pin 52 projecting from the face of gear 38. 53 is a pin
seated in one of a series of openings in the slotted end of pitman 51 which is
adapted to engage pin 49" of rock-arm 49 for moving the pawl 46 rearwardly
upon the ratchet-wheel 45. The pawl 46 is moved forwardly intermittently
for rotating the ink-fountain roller 31 step-by-step by the engagement of the
upper end of slot 50 of pitman 51 with pin 49". By adjusting the pin 53_to
the different holes of the series in pitman 51 the stroke of the pawl 46 can be
regulated to rotate the fountain roller 31 more or less. 54 is a hand-lever formed
integral with the hub of rock-arm 49 by which the ink fountain-roller 31 can
be rotated by hand under certain conditions. The gear-wheel 38 on shaft 39
meshes with a small gear 55 secured to gear 42 and splined (with said gear 42)
to shaft 41 and held against endwise movement by a bracket bearing 42 so
as to allow shaft 41 to move longitudinally through said gears. The shaft 39
is driven from the main driving gear 11 through gears 43, 42, 55 and 38. The
gear 43 is journaled upon a stud carried by the downwardly projecting frame
piece 1ª.
The shaft 41 at the vibrator-side of the machine is provided with a grooved-
collar 56 with which engages a rock-arm 57 journaled at 58 and formed integral
with another rock-arm 59 engaging in the groove-cam 60 keyed to the shaft 39
adjacent to the vibrator-side of the machine. By the operation of cam 60 through
rock-arms 59, 57 and collar 56 the inking-drum 40 is caused to continually
vibrate longitudinally in its bearings, its shaft 41 sliding in the gears 55 and 42.
61, 61, 62 and 63 are ink-mixing rollers and 61, 62, 63 are rider-rollers,
all journaled in bearings in the upper extensions of the side-frames of the
machine, the mixing rollers being supported in peripheral contact with the
ink-drum 40 and the rider-rollers in contact with the mixing-rollers. At the
vibrator-side of the machine the journals of the rider-rollers 61, 6:3 carry
grooved wheels 61, 633b with which engage the bearing blocks 64, 65 mounted
upon the upper ends of rock-arms 66, 67 which are rigidly connected with a
rock-arm 68. The rock-arms 66, 67 and 68 are journaled in a suitable bracket 69
upon a pin 70, and the rock-arm 68 carries a journal-block 71 which engages a
grooved-collar 72 keyed to the outer end of shaft 41. By this means the ink
rider-rollers 61 and 63" are vibrated longitudinally in engagement with the
mixing-rollers, the rider-rollers moving in one direction when the ink-drum
moves in the opposite direction and vice versa.
75 is a vertically extending shaft journaled upon the vibrator-side of the
machine in bracket-bearings 76, 77 the upper end of the shaft carrying a bevel-
gear 78 which meshes with a similar bevel-gear 79 keyed to the transverse
shaft 39. 80 is a bevel-gear keyed to shaft 75 just above bearing 77 and 81 is
a similar bevel-gear keyed to the forward end of vibrator-shaft 82 which is
journaled in bracket-bearings 83, 84 and extends horizontally of the machine.
The vibrator-shaft 82 operates the vibrating rock-arms which are operatively

page_text: connected with the vibrating distributor rollers of the form inking mechanism
which will now be described.
85 and S6 are end-frames or stands comprising the vertically movable franie
which supports the form inking rollers and ink distributor-rollers. The
frames 85, 86 are of arch shape for supporting the inking rollers in proper
relation to the form-cylinder, the ends of the frames being formed with vertical
guide-grooves 87 engaging the vertical guide-tongues or flanges 88 of the frame,
the stands 85, 86 being movable vertically upon said guides. Each of the end-
frames or stands is formed with forked bearing arms 89 extending radially from
the centre of rotation of the form-cylinder for the reception of the journal ends 90°
of the ink distributor-rollers 90. Between the bearing arms 89 are slots 91
for the reception of journal-ends 92 of the form inking rollers 92, the journal
ends of said form inking rollers being supported in the bracket-bearings 93
formed integral with the pins 94 mounted in sockets formed in brackets 95. The
brackets 95 are secured to the face of stand or frame 85 or 86 by means of tap-
bolts 96 and 97 which pass through circular opening 96 and elongated opening 97"
respectively and are seated in suitably threaded openings in the face of the stand
or frame 85 or 86. 90 are intermediate rider-rollers.
98 is an adjusting screw supported in the cavity 98" in the face of bracket 95
and engaging the interiorly threaded bore 94" of the bracket-pin 94. The head
of adjusting serew 98 rests upon a shoulder of cavity 98" so that by turning the
screw 98 the bearing-brackets 93 can be adjusted up or down in the bracket 95
whereby the form inking-rollers can be nicely adjusted with relation to
the form-cylinder: By loosening bolt 97 the brackets 95 can be adjusted to the
proper radial position upon the side-frame or stand 85 or 86 with relation to the
centre of rotation of the form-cylinder.
100 are arms journaled to the upper extensions of side-frames of the press
upon a rock-shaft 101 and formed with upwardly and downwardly extending
slotted arms or forks 102 and 102" in which are supported the transfer inking-
roller 103 and rider-roller 104. The transfer-roller 10% operates in peripheral
engagement with the ink-drum 40 and with one of the ink distributor-rollers 90.
100 is a hook upon the press-frame adapted to engage a pin 100b on one
of the arms 100 to support the arms in elevated position when the rollers 103
and 104 are removed. 105 are rock-arms journaled at 106 to the side-frames of
the press and supporting in their upper forked-ends the ink transfer-roller 107
which operates in peripheral contact with the ink-drum 40 and with another
one of the ink distributor-rollers 90. The rock-arms 105 can be moved forwardly
upon their bearings 106 for removing the transfer roller 107.
Journaled at each side of the machine frame at 110 is a large rock-arm or
lever 111 or 112 which engages one of the anti-friction rollers 113 journaled
at 114 upon the side-frames or stands of the vertically movable ink-roller
supporting frame. The anti-friction roller's 113 are located perpendicularly
above the centre of rotation of the form-cylinder so that the lifting action of the
rock-arms or levers 111, 112 will be exerted in a vertical direction.
•
Journaled upon pins 115 in each of the machine side-frames are grooved
anti-friction.rollers 116, 117, upon which are supported the longitudinally movable
cam-bars 118 having inclined or cam surfaces 119. Upon each of the stands or
frames 85, 86 above anti-friction-rollers 116, 117, are journaled the grooved anti-
friction-rollers 120, 121 which rest upon the inclined or cam-surfaces 119 of the
bar 118. 122 is a rock-shaft extending across tire machine, from the opposite ends
of which extend the rock-arms 123, 124 having loose pivotal connection with the
rear ends of the. cam-bars 118. 125 and 126 are other rock-arms projecting from
rock-shaft 122 adjacent to rock-arms 123, 124 respectively, the rock-arm 125 being
connected to a link 127 with a lug 111ª formed on the lever 111 while the rock-
arm 126 is formed with a cam-face 126ª which rests upon a cam-face 112" of the
rock-arm 112..
130 is a rock shaft journaled in the machine side-frames and extending from

page_text: side to side. 131, 131 are rock-arms keyed to rock-shaft 130 at opposite sides
of the machine extending upwardly therefrom and pivoted to downwardly extend-
ing arms or links 132, 132 which are pivotally connected at their upper ends with
the rock arms or levers 111, 112. The rock-arms or levers 131, 131 and
links 132, 132 constitute toggle-links or levers at the sides of the machine, by the
straightening and breaking of which the stands or frames 85, 86 carrying form-
inking-rollers 92 and ink-distributor-rollers 90 are raised and lowered. At the
vibrator-side of the machine a groove-cam 133 is secured to the end of the form-
cylinder 5, and journaled upon a suitable stud 134 is a rock-arm 135 carrying
upon a suitable lug an anti-friction roller 135ª which operates in the groove-
cam 133. Journaled to the lower end of the rock-arm 135 is a link 136 formed
with oppositely extending connected slots 136, 136b which slots have adjacent
to their junction upwardly and downwardly engaging shoulders 136° and 136d.
Depending from the rock-shaft 130 at the vibrator-side of the machine is a
rock-arm 137 carrying at its free end an anti-friction roller 138 which plays in the
oppositely extending connected slots 136 and 136b of the link 136.
Journaled upon the lower end of the link 136 is a bearing-block 140 through
which passes a rod 141 extending rearwardly to a rock-arm 142 which is keyed
to rock-shaft 143. Extending up from the rock-shaft 143 is a controlling
hand-lever 144. The rock-shaft 143 is journaled in bearing-brackets 143* and
extends from side to side of the machine, the rock-arm 142 being on the vibrator-
side of the machine inside of the frame, while the controlling hand-lever 144 is at
the gear-side of the machine outside of the machine-frame. Mounted upon the
rod 141 is an expansion spring 145 which is confined against the bearing-
block 140 by a collar 146 secured to the rod 141. The rod 141
also extends forwardly from the bearing-block 140 to a bearing 148
pivoted on the machine frame, and
is
a compression spring 149
mounted upon the rod 141 and confined between the bearing-block 140
and the bearing 148. When the lever 144 is in its rearmost position,
shown in Figure 13, the spring 149 is of sufficient strength to resist the pressure
of spring 145 and hold the slotted link 136 in the position shown in Figure 13,
the anti-friction roller 138 of rock-arm 137 playing in the upper slot 136 when
the parts are in this position. By moving the hand-lever 144 forwardly upon its
rock-shaft 143, the spring 145 is compressed to a sufficient degree to force the
link 136 forwardly against the pressure of spring 149, causing the anti-friction
roller 138 to be engaged by the downwardly engaging shoulder 136d, the parts
then being shifted into the position shown in Figure 12. The engagement of
downwardly engaging shoulder 136d with anti-friction roller 138 rocks the rock-
arm 137 and straightens the toggle links or levers 131, 131, 132, 132 for lifting the
stand or frame carrying the form inking-rollers and ink distributor-rollers.
When the link is in the opposite position the upwardly engaging shoulder 136°
moves rock-arm 137 upwardly for breaking the said toggle-links or levers to allow
the frame or stand to move downwardly and throw the form inking-rollers into
engagement with the form-cylinder.
Journaled upon the bearing-bushing 7 is a circumferentially movable frame or
spider 150 having a journal-bearing 150. The frame or spider 150 is located at
the gear-side of the machine between the distributor-rollers' operating gear 17
and the machine side-frame 1, and has integral flanges 150b arranged to engage
and slide upon the face of vertically movable frame 85, and a curved flange 150°
which engages the inner face of driving gear 17. The flanges 150b, 150b and 150°
steady the frame 150 and prevent any transverse vibrations at the opposite sides
of the vertical central line. The frame or spider 150 carries a series of studs 151
upon which are journaled the small intermediate gears or pinions 152, which are
supported in constant mesh with the driving gear 17 and with the distributor-
roller gears 90b keved to the journal ends 90% of the distributor-rollers. The
circumferentially movable stand or frame 150 is formed with oppositely arranged
inclined slots 153 in which engage the anti-friction-rollers 154 journaled upon

page_text: pins or studs projecting outwardly from one of the longitudinally movable cam-
bars 118, the longitudinal movement of said cam bar by the means above described,
causing the frame or spider 150 to be shifted slightly circumferentially, for the
purpose of moving the intermediate gears 152 toward or away from the radial
lines extending from the centre of the form-cylinder through the journals of the
distributor-rollers. The frame or spider 150 is shifted simultaneously with the
up and down movement of the vertically movable frame 85, 86, which supports
the form inking-rollers and ink distributor-rollers, the intermediate gears 152
being moved toward said radial lines when the inking-rollers are raised, so as
to bridge the increased space between gears 90b and driving gear 17, and away
from said radial lines when the inking-rollers are lowered toward the form-
cylinder to allow for the necessary movement of gears 90b toward gear 17, and in
this way the distributor-rollers are maintained in constant positive gear with
their driving gear 17 in order that the ink upon the rollers will be kept in worked-
up condition.
Keyed to the vibrator-shaft 82 above referred to are the groove-cams 160, 161,
162, 163. The alternate ink distributor-rollers 90 at the vibrator-side of the
machine are provided on their journal-ends with grooved collars 165, in which
engage the bearing-blocks 166 journaled upon the upper ends of rock-arms 167,
168, 168 and 170. Each of the rock-arms 167, etc., is formed integral with
or rigidly secured to a downwardly projecting rock-arm 167, 168*, 169"
or 170 which engage respectively in the groove-cams 160, 161, 162 and 163,
whereby the alternate ink distributor-rollers are vibrated longitudinally in their
bearings, said distributor-rollers being in peripheral contact with the form inking-
rollers supported beneath them.
The form moistening or dampening devices will now be described. 175 is
the water-fountain extending from side to side of the machine and supported
from the side frames upon suitable brackets 176. 177 is the water fountain-
roller journaled in the machine side-frame, the journal 177 at the vibrator side
of the machine projecting beyond the machine side frame and having keyed to
it a bevel-gear 178 which meshes with a similar bevel-gear 179 keyed to a
short vertically extending shaft 180 which is journaled in bracket-bearings 181
secured to the machine side-frame. The shaft 180 is in line with the shaft 75,
a clutch being provided to couple the shafts 75 and 180, said clutch comprising a
fixed member 182 secured to the lower end of shaft 75 and a movable member 183
having spline connection with the upper end of shaft 180. 184 is a bell-crank
hand-lever journaled at 185 and engaging the movable member 183 of the clutch
for throwing the shaft 180 into or out of gear with the shaft 75. By this means
the water-fountain-roller 177 and water ductor-roller 195 may be temporarily
arrested, at such times, for instance, when the water form-rollers become charged
with too much water and it becomes desirable to work off the surplus. The
water-ductor 195 is operated by a cam 200 carried on the journal of fountain-
roller 177 at the gear-side of the machine, as will be hereinafter explained.
186 is the water distributor-drum having elongated gudgeons or axle bear-
ings 186 which are journaled in the bearing-sleeves 203 supported in the side-
frames of the machine. The axle-bearing 186 at the gear-side of the machine has
keved to it a small gear-wheel 187 which is in constant mesh with an inter-
mediate gear 188 journaled upon a stud 189 and meshing in turn with the dis-
tributor-roller driving-gear 17. The journal-end 186 at the vibrator-side of the
machine has keyed to it a grooved collar 190 which is engaged by a rock-arm 191
journaled upon pin 192 from which projects a second rock-arm 193 integral
with arm 191 and engaging in a groove-cam 194 keved to the short shaft 180.
By this means the water distributor-drum 186 is vibrated longitudinally in its
bearings, its driving gear 187 being of sufficient width to maintain its mesh with
gear 188.
195 is the water ductor-roller journaled at its ends in the upper ends of rock-
arms 196 keyed to a rock-shaft 197 journaled in the side-frames of the machine.

page_text: The rock-shaft 197 projects beyond the side-frame at the gear side of the machine
and supports an adjustable rock-armı 198 which has spline and groove connection
with the shaft 197 and carries in its free end an anti-friction roller 199 which runs
in peripheral engagement with the conoidal cam 200 keyed to the projecting
journal-end or shaft 177 of the water-fountain roller 177. The rock-arm 198
is adjustable upon the rock-shaft 197, the arm 198 having a downwardly project-
ing integral lug 198" into which is threaded an adjusting screw 201 journaled in
a suitable opening in the arm 202 which is rigidly secured to the end of shaft 197.
The screw 201 has a milled hand-wheel 201 by which it is operated. By this
means the rock-arm 198 may be adjusted axially with relation to its operating
cam 200, for moving it into the path of the extreme low part of the cam, or
the higher parts, to vary the time of contact with the water-fountain-roller and
consequently the quantity of water transferred from it to the water form-rollers
which will now be described.
The sleeves 203 extend inwardly from the side-frames and each supports a
pair of shear-like levers 204 and 205, said levers being journaled upon said sleeve
and confined in position by a collar 203 fixed rigidly to the sleeve 203. The
shear-lever 204 supports an adjustable bracket arm 206 by means of a thumb-
screw 207 which passes through a slot 208 in arm 206 and is threaded into an
interiorly threaded opening in boss 204. The bracket-arm 206 is adjustably
confined in proper position upon the shear-lever 204 by means of the adjusting
thumb-screw 207 and 209 which are threaded in suitable shoulders 204 and 209b
respectively and engage the bracket-arm 206 below and above. The bracket-
arm 206 is formed with a forked bearing socket 200" in which rests one of the
journals 210 of the lower water form roller 210. The journal 210* is supported
in the bearing-socket 200 by slotted bearing-arm 211 confined upon bracket-
arm 206 by the thumb-screw 212 which passes through the slot of bearing-arm 211
and is seated in the threaded opening in bracket-arm 206. By adjusting the
several parts just described, the position of the bracket-arm 206 upon the shear-
like lever 204 can be regulated to a nicety to bring the water form-roller 210 in
proper relation with the form-cylinder 5. The upper shear-lever 205 supports
à bracket-arm 213 by means of a thumb-screw 214 which passes through a
slot 213 of the bracket-arm 213 and is seated in threaded opening in the shear-
lever 205. 215 is a thumb-screw threaded into a lug 215 of shear-lever 205
and engaging a shoulder 213b of the arm 213 for adjusting the position of the
arm 213 upon the shear-lever 205. 216 is the upper water forin-roller whose
journal 216 is supported in the forked bearing-socket 213 of bracket-arm 213,
the journal 216" being secured in the bearing socket by means of the bearing-
block 217 secured in place by thumb-screw 218. It will, of course, be under-
stood that the shear-like levers 204, 205 and their above-described connected
parts are duplicated at each side of the machine, the water form-rollers 210
and 216 being supported at their opposite ends by said shear-like levers.
Each pair of shear-like levers 204 and 205 is provided with an operating toggle
comprising links 220 and 221 which are journaled respectively to the shear-
levers 20 and 205 at points 220 and 221" and are journaled to each other at
point 222 223 is a transversely extending rock-shaft journaled in the side-
frames of the machine and supporting adjacent to each end, a rock-arm 224 which
is journaled to the knuckles 222 of the toggle-levers 220, 221.
At the gear-side of the machine a long rock-arm 225 is keyed to rock-shaft 223
and extends rearwardly therefrom and is provided at its end with stud 226 which
operates in a slot 227 formed in the lower end of the reciprocating link 228
journaled at 229 upon a bell-crank rock-arm 230, 231 journaled at 232. The
bell-crank rock-armi 231 supports an anti-friction roller 233 which operates in a
groove-cam 234 secured to the form-cylinder 5 at the gear-side of the machine.
235 is a leaf-spring secured to reciprocating slotted-arm 228 and engaging the
rock-arm 230 for the purpose of giving the reciprocating arm 228 a forward
fendency on its suporting journal 229. At the lower end of the slot 227 in the

page_text: arm 228 is formed a notch 227ª having upwardly and downwardly engaging
shoulders. The reciprocating arm 228 engaging rock-arm 225 rocks the arms 224
for successively straightening and breaking the toggle levers 220, 221 to rock the
shear-levers 204 and 205 and cause the water form-rollers 210 and 216 to be
moved intermittently into and out of peripheral engagement with the form-
cylinder. The water-form rollers 210 and 210 rotate in peripheral contact with
the water-distributing drum 186, which is operated as above described and
receives intermittently a charge of water from the water ductor-roller 195 in the
manner already described. When the machine is operating the water form-
rollers 210 and 216 are moved successively into the positions shown in Figures 20
and 21, the position shown in Figure 29 being the one assumed when the printing
form is passing the water form-rollers, while the position shown in Figure 21 is
the one assumed when the segmental ink distributing surface of the form-cylinder
is passing the water-form-rollers.
The reciprocating slotted arm or link 228 is formed with a downwardly project-
ing toe 228 with which is adapted to engage an arm 236 keyed to a rock-shaft 237
journaled in bracket-bearing 237 of the press-frame, the engagement of arm 236
with toe 228 being for the purpose of moving the arm 228 forwardly upon its
journal 229 to disengage the stud 226 from the notch 227" of slot 227. The rock-
shaft 237 has keyed to it a segmental gear 238 which meshes with a similar
segmental gear 239 keyed to a rock-shaft 240 journaled in a bracket-bearing 241
of the press-frame.
The rock-shaft 240 has rigidly mounted upon it an arm 242 which is adapted
to engage the under face of the long rock-arm 225 for moving and supporting it
in its raised position, holding the toggle links 220, 221 in broken position with
the water form-rollers 210 and 216 supported out of contact with the form-
cylinder. When the arm 242 supports rock-arm 225 in raised position the
arm 236 will hold the slotted link 228 in its forward position, these simultaneous
movements being ensured by the segmental gears 238 and 239, and in this
position the slotted link 228 is allowed to reciprocate vertically under the action
of its operating cam 234 without interfering with the inoperative position of the
water form-rollers, the stud 226 playing in the vertical slot 227 during this
inoperative position of the parts. The throwout mechanism of the water form-
rollers may be operated by a short hand-lever 245 keyed to rock-shaft 237 or
by means of rock-arm 246 keyed to rock-shaft 237 and connected by rearwardly
extending rod 247 to a foot-lever 248 journaled at 249 in bracket 250 and extend-
ing up through a slot 251 in the platform 252 of the press-frame. The lever 245
is located adjacent to the forward end of the press while the foot-lever 248 is
located adjacent to the rear end of the press.
The impression-cylinder 20 has its gudgeons or axles 23 journaled in eccentric
bearing-bushings 24 and 25 supported in the side-frames of the machine, as above
explained. Each of the bearing-bushings 24 and 25 is provided with a rigid
arm 260 which is journaled at 261 to the upper link 262 of the pair of toggle
links or levers. The link 262 is journaled at 263 to the lower toggle link or
lever 264 which is keyed to a rock-shaft 265 journaled in the side-frames of the
machine. The upper link 262 is formed in two parts connected by the adjusting-
screw 262 by which link 262 can be lengthened or shortened.
At the gear-side of the machine the rock-shaft 265 is provided with a rock-
arm 266 carrying at its end a stud 267 supporting an antifriction roller which
plays in the oppositely extending connected slots 268, 268b formed in the lower end
of the reciprocating link 268. The link 268 is journaled at 269 to rock-arm 270
which is journaled at 271 and supports on the lug 272 an anti-friction roller 273
which operates in the groove-cam 274 secured to the impression-cylinder 20 at
the gear-side of the machine. The oppositely extending connected slots 268", 268b
of the reciprocating link 268 form downwardly engaging shoulder 268° and
upwardly engaging shoulder 268d which are adapted to engage the anti-friction
roller supported on stud 267 for the purpose of straightening and breaking the

page_text: toggle links 262, 264 for moving the impression-cylinder 20 into and out of
operative relation with the form-cylinder 5.
275 is a rock-shaft to which is keyed a rock-arm 276 carrying an anti-friction
roller 277 which rests normally against a straight face 268 of the reciprocating
link 268.
278 is a rod connected to the rock-arm 276 and extending forwardly through
a bracket 279 journaled at 280 to the side-frame of the machine. 281 is an
expansion-spring surrounding rod 278 and confined between the bracket 279 and
an adjusting-collar 282 secured to rod 278. The spring-actuated rod 278 operat-
ing through the rock-arm 276 holds the reciprocating slotted link 268 normally
in the position shown in Figure 30, the impression-cylinder being in this position
in operative relation to the form-cylinder.
285 is another rock-arm keyed to rock-shaft 275 and 286 is a lever journaled at
287 to bracket 288 and pivotally connected to rock-arm 285 at 289 the rock-
arm 285 and lever 286 constituting a toggle. 291 is an operating-arm
journaled to lever 286 at 292 and extending up through an open-
ing 293 in
the platform 252 of the press, the operating arm 291
being provided with an integral locking-lug or shoulder 291ª which
is adapted to engage the under face of platform 252 when said arm is
depressed, the arm being supported in a slightly inclined position for the purpose
of ensuring the engagement of the locking lug 291" automatically when the
arm 291 is depressed. 291b is a foot-plate on the upper end of arm 291 by which
it is operated.
295 is a rod journaled to the lower end of slotted link 268 and extending
rearwardly through a bracket-bearing 296 journaled to the side-frame of the
machine. 297 is an expansion-spring supported upon rod 295 and confined
between the bracket-bearing 296 and an adjustable collar 298 secured to rod 295.
The spring 281 is stronger than the spring 297 so as to ensure holding the
slotted link 268 in its rearmost position when the operating-arm 291 is released
from its engagement with the platform 252.
300 is a pin or lug projecting from the face of the rock-arm 285.
301 is a
vertically movable operating rod passing through a suitable opening in the plat-
form 252 formed at its lower end with an elongated slot 302 which engages a
pin 3033 secured to a rock-arm 304 which projects from the rock-shaft 305.
operating-rod 301 is provided at its upper end with a step 301". 306 is a foot 3
secured to the operating rod 301 in position to engage the pin or stud 300.
The
The rock-shaft 305 is journaled in bracket-bearings 306 of the press-frame and
extends forwardly to a point directly beneath the main driving-shaft 13. 307 is
a brake-arm keyed to rock shaft and extending directly beneath the fly-
wheel 308 which is keyed to the driving-shaft 13. 310 is another rock-shaft 4
extending parallel with the rock-shaft 305 and having keyed to it the forked belt-
shifting arm 311 which embraces the belt 16 in a manner well understood.
312 and 313 are segment-gears meshing with each other and keyed respectively
to the rock-shafts 305 and 310 so that when rock-shaft 305 is rocked by depressing
the operating rod 301, the brake 307 will be pressed against the periphery of 4
fly-wheel 308 and the belt-shifting arm 311 will be moved to throw the belt 16
from the fast to the loose driving pulley. 315 is a long operating lever keyed to
rock-shaft 310 for shifting the belt and applying the brake for stopping the
machine. The operating rod 301 is only used when it is desired to throw out the
impression-cylinder simultaneously with the application of the brake and throwing 5
off of the driving belt, the foot 306 engaging pin or lug 300 causing the throw-
out of the impression-cylinder, as above explained. When the operating rod 301
is depressed the toggle link or lever 285 will be forced down and the locking-
Jug 291 of arm or lever 291 will engage the under face of platform 252 and hold
the parts in this position. After the machine is again started, by removing the 5
brake and shifting the belt by the operation of lever 315, the arm or lever 291

page_text: is disengaged to allow the spring device 281 to return the parts to their normal
position and effect the throwing in of the impression-cylinder.
325 is the sheet delivery cylinder journaled in bearings 326 and provided with
sheet delivery grippers 327 which may be of any suitable construction adapted
to take the successsive printed sheets from the grippers of the impres-
sion-cylinder. 329 are a series of delivery bands which
pass around
the delivery cylinder 325 and a delivery roller 330 journaled in bracket
bearings 331. 335 is the delivery fly journaled at 336 in the side frames.
The delivery-fly 335 is adapted to take the sheets from the supporting delivery
bands 329. 338 is a segment-gear keyed to the rock-shaft of delivery fly 335
and 3:39 is a rack-bar engaging the segment-gear 338 and passing forwardly
through a bearing 340 attached to rear part of machine-franie, and a bearing
collar 341 resting in a forked bracket 342 secured to the machine-frame below
the impression-cylinder 20. The bar 339 extends through fork of bracket 342,
its forward end being journaled to a bell-crank 343 journaled at 344 and carry-
ing an anti-friction roller 345 operating upon the cam 346 keyed to the gudgeon
or axle 23 of the impression-cylinder 20. 347 is an expansion-spring supported
upon bar 339 and confined between bearing 341 and an adjustable collar 348
secured to the bar 339. The cam 346 draws the bar 339 forwardly for raising
the delivery fly, (incidentally compressing the spring 347). The spring 347
when released by the cam 346, throws the delivery fly over into horizontal posi-
tion for delivering the sheet received from the delivery-bands. 349 is a gravity
hook journaled at 350 and adapted to engage a lug 335" on the fly frame to hold
the fly in inoperative position when the delivery mechanism is not opera-
ting, the spring 347 being held in compressed position and the bell-crank 343
being prevented from following the cam 346. A crank-arm 352 on rock-shaft 336
of the fly is connected with a sheet register 353 through chain 354 as usual. 355
is the platform upon which the sheets are delivered by the fly.
From the above detailed description of the several sets of mechanisms employed
in this improved printing press, the operation of the press as a. whole will be
clear from a brief description which will now be given.
When the machine is operating the form inking mechanism is in the position
shown in Figure 13, the form inking rollers being in contact with the form-
eylinder; the impression-cylinder is in peripheral contact with the form-cylinder;
and the water form-roller mechanism is in the position shown in Figure 20.
Sheets are fed from the table 26 to the impression-cylinder and the grips carry
the sheet around with the impression-cylinder receiving an impression from the
form-cylinder, the form being first moistened by the water form-roller mechan-
ism and next inked by the inking-mechanism. The printed sheet is delivered
to the delivery-mechanism in the usual way. If it is desired to throw out the
water form-mechanism the lever 245 or lever 248 is moved forward, disengaging
rock-arm 225 from the notch 227 of slotted link 228 and holding the shear-
levers 204 and 205 in inoperative position with the water form-rollers 210, and
216 out of contact with the form-cylinder. If it is desired to throw the form
inking-mechanism out of operation, the hand-lever 144 is moved forwardly, com-
pressing the spring 145 against the lower end of slotted link 136 so as to cause
the upwardly engaging shoulder 130 to rock the arm 137, straightening the
toggle links 131, 132, and moving the inking-roller supporting-frames 85, 86
upwardly away from the form-cylinder. Simultaneously with the upward move-
ment of the supporting frames 85, 86 of the inking-mechanism, the circumfer-
entially movable frame or spider 150 will be moved by the engagement of anti-
friction-rollers 154 with slots 153 for the purpose of shifting the intermediate
gears 153 toward the radial lines extending from the centre of rotation of the
form cylinder through the journal centres of the distributor-rollers 90, thereby
bridging the increased space between the distributor-roller gears 90b and their
driving gear 17. When so shifted the parts assume the position shown in

page_text: Figure 12. When it is desired to arrest the rotation of the form-cylinder with
the form inking-mechanism out of operative relation thereto, the form-cylinder
clutch 10 is thrown out by the operation of clutch-lever 18, the main driving-
gear 11 and distributor-rollers' operating gear 17 being rotated from the main-
shaft 13 to keep the drum 40, the ink-mixing rollers, ink form-rollers, and ink
distributor-rollers in operation for working up the ink or maintaining it in proper
worked-up condition. To throw out the impression-cylinder, the foot-lever 291 is
depressed causing the spring-pressed arm 276 to be moved away from the plain
face 268 of the reciprocating slotted link 268, allowing the spring 297 to force
the lower end of link 268 forwardly and cause the rock-arm 266 to be engaged
by the upwardly engaging shoulder 268d for breaking the toggle links 262, 264
and rotating the eccentric bushings for moving the impression-cylinder away
from the form-cylinder. It will, of course, be understood that this movement
to and from the form-cylinder is very slight, the delivery-cylinder 325 being a
sufficient distance in rear of the impression-cylinder to allow for said movement.
By disengaging the lug 291" of foot-lever 291 from the platform 252, the
spring 281 will throw back the arm 276 into engagement with link 268 for
causing the reverse movement of the parts. Figure 30 shows the impression-
cylinder and controlling-mechanism in operative position while Figure 31 shows
the parts in inoperative position.
In the ordinary operation of the machine the hand-lever 144 controlling the
inking-mechanism and foot-lever 291 controlling the impression-cylinder throw-
out are utilized. In case of an emergency, however, it is sometimes necessary
to immediately stop the whole machine. For this purpose the emergency stop 301
is provided which, in the manner above explained, throws out the impression
cylinder, shifts the belt and applies the brake for immediately arresting the
operation of the machine. At the same time the emergency stop is operated,
the levers 144 and 248 may also be operated for throwing out the ink-mechanism
and water form-roller mechanism respectively. It will be observed that the
several controlling levers of the machine are in convenient position for the opera-
tor who stands upon the platform 252 and feeds the sheets from the feed-table 20.
The operations of the several parts are more specifically described in connec-
tion with the detailed explanations above given.
The part of the invention illustrated in Figures 33 to 37 of the drawings re-
lates to improvements in the paper carrier which is preferably of cylindrical
form, and in the front gages or guides; the improved carrier and gages being
constructed to cooperate in the manner hereinafter described. The especial
object of these improvements is to furnish support to the sheet of paper, when
fed by the gages, across the gripper gap, at the gage edge, whereby the sheet
will be delivered on the carrier surface true and flat.
In effecting this result the off side of the carrier or impression cylinder is
made about as high as the impression side, the impression side being covered
with the usual packing or blanket, making it somewhat higher than the off side.
Very shallow grooves are preferably provided in the off surface, of such small
width as not to substantially interfere with the contiguity of said surface, and the
front guides or gages are so constructed and arranged as to just enter these
grooves, thus effectually preventing the edge of the sheet from slipping under the
gages. Across the gripper gap are arranged the bridge pieces or supporting
fingers, some of which will be exactly in line with the gages, so that said fingers
will move through recesses in the lower edge of the blade of the gages as the
paper carrier or impression cylinder rotates. These fingers are nearly the same
height and curvature as the surface of the paper carrier, being about the same
radius as the off side of cylinder, and running up on to the packing or blanket
which covers the impression side, and therefore they support the sheet across
the gripper gap.
In a modified construction the grooves are omitted in the off surface of the
paper carrier, and the supporting fingers are arranged the least possible above

page_text: the off side surface of the paper carrier, said fingers moving through the recesses
in the edges of the blades of the gages as before.
The paper carrier or impression cylinder 20 rotates in the direction of the
arrow, Figure 33, and carries the paper against the form or printing plate (not
shown) in the well known manner. 26 is the feed board from which the sheets
are fed, provided with a side gage and arranged in the well known manner.
Grippers C are carried in the gap in the well known manner.
E, E are the front gages or guides. Said gages are lifted through the medium
of the cam k on the head of the shaft 23 of the cylinder 20 and the roller f' on
the rod f which is pivoted to the arm gl of the cross shaft g, on which are fixed
the gages by set screws as shown in Figure 34. The blades e of said gages E
are provided with recesses e¹ in their lower edges, which recesses span the sup-
porting fingers H. (Figure 35)
The surface of the off side of said paper carrier or cylinder 20, that is the side
to the left of gripper gap D, is provided with several shallow and rather narrow
grooves jj (Figure 34) certain of which are in line with the said blades e of the
front gages, and cam k is so set that, as the off side of paper carrier A comes
under the said blades e, the said cam will permit said gages to descend and the
blades e to enter said grooves jj, but preferably not to descend to the bottom of
the grooves; the drop of the gages being regulated by the arm m¹, which is
secured to the shaft g and has at its free end an adjusting screw m² which, when
the guides or gages are down, strikes the fame 7, and by means of which the
guides or gages may be set to the desired amount of entrance into the grooves,
and the front guides remain down until just before the grippers C close on the
sheet of paper, when the said cam raises the gages to the position of
Figure 33. Therefore when the gages are down the front edge of the sheet of
paper cannot slip under the blades e.
HH are bridge pieces or sheet supporting fingers, which preferably consist
of thin strips of spring steel, made to fit easily in the recesses c¹ of the blades e,
and fixed on blocks, which are movable and adjustable by set screws on the
shaft, which shaft is carried in bearings across the gripper gap D.
C'ertain
of said fingers II as shown are exactly in line with recesses e¹ of said blades,
so that, as the cylinder or carrier 20 moves, the fingers will move through said
recesses. The other fingers may either be in line with the grooves in the car-
rier 20, or between them, and the set screws allow of accurately adjusting them
to any desired position. On end of said shaft 1, is fixed an arm m, with a hole
into which enters a pin through the head of carrier 20. This pin holds the shaft
in the proper position to keep the one end of the said fingers H on the bevel of
the impression side of the gripper gap, and the other, or rear end of said fingers,
just at the off side of said gap, so that said fingers completely span the gap and
support the sheet over the same, so that it cannot crease or buckle. By withdraw-
ing said pin from the arm m, the shaft / can be turned so as to raise the fingers H
and give access to the gap for any purpose, as to change the blanket.
In the modification shown in Figures 36 and 37, the supporting fingers H¹
are shown just slightly above the off side of carrier 20, so that the gages E rest-
ing on the off side, as the carrier is turned, the supporting fingers enter into the
recesses e¹ of the said gages E, and prevent a sheet slipping under the gages.
Thus the grooves in the off side of the carrier may, in some cases, be dispensed
with, or both the grooves and the surface of the off side may be used together:
as, for instance, when two feeders are feeding separate sheets at opposite ends of
the carrier, and the gages are placed for their respective sheets, the lower edge of
blades e being beveled to form knife edges, as shown, to ride upon the surface
of off side when placed in a position to do so.
Referring now to Figures 38 to 45 of the drawings a modified form dampening
mechanism will be described. 11 is a main driving gear loosely journaled upon
an extension of the axle or gudgeon of the plate cylinder 5 and having clutch
connection 10 therewith. The gear 11 is suitably driven by a small gear 12

page_text: (sec Figure 25) and in turn drives an intermediate gear 43 which rotates gears 42
and 55, the latter one of which meshes with a larger gear 38 keyed to the end
of shaft 39 which extends from side to side of the machine and is journaled in
the side frames. The shaft 39 has a bevel gear 79 keyed to its end which meshes
with a small bevel gear 78 keyed to the upper end of a vertical shaft 75 journaled
in bracket bearings 19 of the side frame 7.
177 is the water fountain roller journaled in the side frames and having
keyed to one end of its axle a bevel gear 178 with which meshes a similar gear 179
keved to the lower end of vertical shaft 75. In this manner the water fountain
roller 177 is constantly driven from the main gear 11. The axle of the water
fountain roller 177 at the gear side of the machine is extended beyond the press
frame for the reception of the water ductor roller operating and controlling
mechanism of improved construction.
216 and 210 are the form dampening rollers and 186 is the water distributor
drum in peripheral contact with the form rollers 216 and 210. These rollers
are suitably supported with relation to the form cylinder and each other and
preferably in the manner hereinbefore described. 195 is the water ductor roller
journaled in the forked ends of rock arms 196 keyed to rock shaft 197 and sup-
ported in position to be vibrated between the water fountain roller 177 and the
water distributor roller 186 by the mechanism which will now be described.
360 is a rock arm keyed to the rock shaft 197 and supporting an adjusting
screw 361 which engages the upper edge of the rock lever 362 which is loosely
mounted upon the rock shaft 197 adjacent to rock arm 360 and extends rear-
wardly above a bracket 363 in which is supported an adjustable limiting
Screw 364. 365 is an antifriction roller journaled upon a stud 366 projecting
from the rock lever 362 in the plane of an adjustable operating and controlling
cam which will now be described.
367 is a small gear or pinion keyed to the shaft or axle of water fountain
roller 177 close up to the side frame 7 and 368 is a gear of the same diameter
having one more tooth than the gear 367. The gears 367 and 368 mesh with an
intermediate gear 370 journaled on a bearing bolt 371 secured in the side frame 1,
the gear 367 rotating gear 370, which in turn rotates gear 368. The gears 367
and 368, having unequal numbers of teeth, will rotate at different speeds and
move relatively to cause the ductor-roller operating cam to rotate slower than
the water fountain roller. 375 is one member or portion of a divided cam jour-
naled upon the water fountain roller axle and formed with hub portions 376
and 377 extending from it at opposite sides. 378 is a second member or portion
of the divided cam. The cam portion 375 is formed with a conical frictional
clutch recess 375" into which projects a conical frictional clutch member 378"
of cam portion 378. A pin 382 projects from the recess 375" and engages a semi-
circular groove 381 in the face of clutch portion 378, to limit the movement of
one portion of the divided cam upon the other. The small gear wheel or pinion 368
is mounted upon the short hub portion 376 of the cam 375 and secured thereto
by pins 369. 379 is a hand wheel formed with a tubular hub portion 380 jour-
naled upon the hub portion 377 of cam member 375, and 378 is the second cam
member secured upon the hub portion 380 of hand wheel 379 by a pin 383. By
the operation of hand wheel 379 the members 375 and 378 of the cam can be
adjusted one upon the other. The cam member 375 is held in position upon the
axle of water fountain roller 177 by means of a nut 384 engaging threaded por-
tion of the axle while the cam portion 378 and operating hand wheel 379 are
held in position upon the hub portion 377 by means of a small hand wheel 389
threaded upon the hub portion 377 and engaging a friction washer 390. The
gear wheel 368 is connected to rotate with the cam portion 375 as above explained
and causes the member 378 to rotate by the frictional means. The antifriction
roller 365 of rock arm 362 rests upon the periphery of the double adjustable
cam 375, 376.

page_text: The operation of this modified form dampening mechanism may be briefly
described as follows:
The water fountain roller 177 is constantly rotated in the manner above des-
cribed, causing the gear 367 to rotate the intermediate gear 370 which in turn
rotates the gear 368 at a slightly decreased speed because said gear 368 contains
one more tooth than the gear 367. The gear 368 causes the adjustable divided
cam 375, 378 to rotate with it and the rotation of the cam 375, 378 causes the
ductor roller to be vibrated back and forth between the water fountain roller
and the water distributor roller. As the rotation of the operating and controlling
cam is a trifle slower than the rotation of the water fountain roller, it will be
observed that the ductor roller will not operate in unison with the rotation of
the water fountain roller, but will always engage a different longitudinal line of
the water fountain roller. In this manner the formation of an ink line upon
the water fountain roller by the transfer of the ink from the water form rollers
and distributor roller to the water fountain roller is avoided.
If it is desired to supply more or less water from the fountain roller to the
distributor roller, the adjustable cam 375, 378 is adjusted by moving the hand
wheel 379 forward or backward upon its bearing, forming more or less of a low
portion or gap in the operating and controlling cam. By means of adjusting
screws 361 and 364 the operation of the parts can be regulated to a nicety.
The invention disclosed in Figures 46 to 49 of the drawings relates to improved
means for preserving exact register between the plate cylinder and impression
cylinder of a rotary printing machine in which the sheet to be printed is carried
upon the impression cylinder. According to this invention the two cylinders
are geared together at both ends by pairs of gears suitably secured to the cylin-
ders, one gear of each pair being adjustable circumferentially of the cylinder,
while the other gear of each pair is rigid upon the cylinder. Upon the opposite
ends of the impression cylinder suitable driving gears are secured by means of
tap bolts passing through holes in the gears and ends of the cylinder, while upon
the opposite ends of the plate cylinder are adjustably mounted other gears which
mesh with the gears on the impression cylinder. The plate cylinder gears aro
adjustably mounted upon the plate cylinder by means of bolts passing through
elongated slots cut through the gears.
"
The importance of this improved structure will be clear from the following
considerations: If only one pair of gears was employed at one end of the plate
and impression cylinders, it is apparent that in case the cylinders are separated
slightly either to allow for the variation of thickness in the stock to be printed
or for the variation of the height of the form or plate upon the plate cylinder,
the gears would be correspondingly separated and on account of the shape of
the gear teeth there would be more or less back lash" between the intermesh-
ing teeth. With the improved structure and arrangement of gears, it will be
observed that should it be necessary to separate the cylinders for any purpose,
such as above indicated, the adjustable gears at the ends of the plate cylinder
can readily be adjusted with relation to the stationary gears upon the impression
cylinder by simply loosening the securing bolts and moving the gears circum-
ferentially forward or backward upon the plate cylinder. In this way the gears
are so set or adjusted that the intermeshing teeth of the adjustable and fixed
gears at one side of the press will engage on their faces opposite to the engage-
ment of the corresponding intermeshing teeth of the adjustable and fixed gears
at the opposite side of the press. In this manner the plate cylinder being driven
at one end by a suitable operating mechanism may be considered to rotate the
corresponding end of the impression cylinder and the opposite end of the im-
pression cylinder to transmit its motion to the opposite end of the plate cylinder
so that the opposite ends of the two cylinders are positively driven by the gears
without any possibility of back lash and without danger of interfering with the
register of the sheets upon the impression cylinder with the form or plate upon

page_text: the plate cylinder. This part of the invention will now be described more in
detail with reference to Figures 46 to 49 of the drawings.
At the left hand end of the plate cylinder 5 is a large gear 9 formed with
slots 9" through which pass the tap bolts 9b seated in suitable threaded openings
in the end of the plate cylinder. The gear 9 rests upon a circular flange or hub
portion 5 of the plate cylinder and by reason of the elongated slots 9" can be
adjusted circumferentially of the cylinder.
The adjustable gear 9 meshes with a gear 22 rigidly secured to the left hand
end of impression cylinder 20 by means of tap bolts 22 which pass through cir-
cular openings in the gear 22 and are seated in suitable threaded openings in
the impression cylinder.
At the opposite or right hand ends of the plate and impression cylinders are
mounted an auxiliary set of gears comprising the adjustable gear 8 formed with
elongated slots 8" through which pass tap bolts Sb seated in suitable threaded
openings in the end of the plate cylinder, and an intermeshing fixed gear 21
secured to the end of impression cylinder 20 by means of tap bolts 21 passing
through circular openings formed in the gear 21 and seated in suitable threaded
openings in the end of the impression cylinder.
By suitably adjusting the main gear 9 and auxiliary gear 8 with relation to
the main fixed gear 22 and auxiliary fixed gear 21 the exact register of the plate
and impression cylinders is preserved.
In Figure 49 is represente. in a mutilated view both ends of the plate and
impression cylinders. The adjustable main and auxiliary gears are so adjusted
that the main adjustable gear 9 meshes with the main fixed gear 22 so that the
lower faces of the teeth of gear 9 engage the upper faces of the teeth of gear 22
and the auxiliary fixed gear 21 meshes with auxiliary adjustable gear 8 so that
the lower faces of teeth of gear 21 engage the upper faces of the teeth of gear 8.
In other words, the adjustable gears are sô adjusted with relation to the fixed
gears that in the operation of the press the main adjustable gear 9 drives the
main fixed gear 22 and the auxiliary fixed gear 21 drives the auxiliary adjust-
able gear 8. In this way all "back lash" is avoided and perfect register of the
plate and impression cylinders is ensured. By means of this arrangement it will
be clear, also, that in case of wear of the gear teeth the adjustable gears can be
properly set up to compensate for the wear and the gearing of the cylinders by
the adjustments can be maintained in perfect working order irrespective of the
wear.
Another desirable feature obtained by the present invention is that the opera-
tor can set one of the cylinders to any desired position with relation to the other
within the range of the elongated slots of the adjustable gears, and at the same
time preserve the feature of accurate register.
