Cylinder Printing Presses.
I, FREDERICK JOHN HARBRIDGE, residing in the Town of Gravenhurst, in the
District of Muskoka, in the Province of Ontario, Canada, Printer, 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:
My invention relates to improvements in cylinder printing presses and the
object of the invention is first-to provide a delivery for the sheet by which
it may be expeditiously taken from the machine without the aid of the impression
cylinder and thereby effect an economy of time in the delivery of the sheet and
further so deliver the sheet that it will be deposited on the receiving table with
the printed side up; secondly-to provide an improved inking apparatus by
which the ink may be more thoroughly and evenly distributed upon the ink
cylinder before it is carried away from it by the inking rollers; thirdly-to
devise a positive means for ensuring the sheet being gripped and held on to the
cylinder and thereby effect a perfect register; fourthly-to provide a simple
means for raising the impression cylinder on its return movement and further-
more an effective throw-off for such cylinder and; fifthly-to provide a simple
accurate and very fine adjustment for the type-bed whereby the impression may
be regulated to a nicety.
These varous objects are carried out by the construction of the machine
arranged and operating as a whole and in detail as hereinafter more particularly
explained.

page_text: In the drawings like letters of reference indicate corresponding parts in each
figure.
A is the main frame of the machine, which is formed in any approved manner
and particularly as hereinafter explained. B is the main driving shaft of the
machine, which is provided with a driving gear pinion B', which meshes with
a gear wheel C₁ on the counter shaft C from which latter shaft the principal
moving parts of the machine derive their operation.
D is the delivery table, which is pivotally supported at the front end of the
machine by the pins d in the frame as indicated. The table D is wedge-shaped
in cross section presenting a fine edge near where the paper is delivered to the
cylinder as indicated. E is the cylinder, which is hollow and is secured on a
cross shaft F, which is supported in. the eccentric bearing sleeves f journalled in
the sliding standards G. The outer ends of the shaft F extend into the blocks f¹,
which are located in the slots h at the upper ends of the swinging arms H, which
are pivoted at the bottom on the cross rod H' extending from side to side of the
frame of the machine and outside of the same.
I is a pitman connected at one end to the gear wheel C₁ and at the opposite
end to the swinging arm H. By means of this pitman I the arms are given their
swinging movement backward and forward, thereby imparting to the cylinder its
longitudinal reciprocating movement between the feeding table 1) and the de-
livery table J shown in dotted lines in Fig. 2. Secured to the shaft F is a gear
wheel K, which meshes with a rack attached to or forming portion of one of
the side bars of the frame of the machine.
L is the bed-plate upon which the type, which is set in the usual manner in a
chase, is placed, and 7 are the tracks at the side of the bed-plate, which support
the collars 21, 31 and 41 on the end of the inking rollers 2 3 and 4. The track!
serves to keep the inking rollers in a proper level position as they pass over the
face of the type. 22 32 and 42 are the spindles of the inking rollers, which are
connected by the rods 43 and 5 at the ends of the spindles to the bar M, which
is pivotally supported at the bottom on the ends of the cross shaft N suitably
journalled in the frame of the machine. Only one bar M is shown and its com-
plement of rods 43 and 5.
The rods 43 and 5 extend through the bent ends m of the bar M and are tension-
ally held by the spiral springs 6 and 7 abutting the upper bent end m and con-
nected at the opposite end to the rods 43 and 5. The rollers 2 3 and 4 derive
their reciprocating movement over the bed by means of the bar M, which is
connected by the rod m¹ to the lower end of the lever Me, which is pivoted at
the top at M. The roller m² is journälled on a stud on the lever intermediate
of its length and is designed to be given a forward and backward movement by
means of the cam groove C (see full lines in Fig. 3, and dotted lines in Fig. 1.)
During the period that the roller is in the portion of the cam groove eccentric
to the shaft C the inking rollers necessarily derive their reciprocating movement
across the bed, but during the period that the roller is in the concentric portion,
such inking rollers will remain directly over the ink distributing roller O.. The
length of the concentric portion of the groove is, it will be understood, arranged
so that the inking. rollers are held stationary over the ink distributing roller
during the period that the cylinder E is deriving its reciprocating movement over
the bed to print and deliver the sheet. The remaining portion of the cam
groove C serves to bring the inking rollers backward and forward over the type
in the bed when the cylinder is returning to its normal or initial position.
The ink distributing roller O is supported in suitable bearings by means of the
spindle O. A. bevel pinion o is provided on the spindle at one end thereof, such
bevel pinion being engaged by a similar pinion o on the end of the spindle o²,
which is journalled in suitable bearings in the frame. The opposite end of the
spindle o is provided with a bevel wheel o³, which meshes with a bevel gear
wheel P secured on the counter, shaft C. The bevel wheel P is of sufficient
diameter so as to drive the ink distributing cylinder O sufficiently fast to properly

and evenly convey the ink to the ink rollers 2 3 and 4 when they are brought in
contact with it.
QQ are the minor distributing rollers, which abutt the major roller O. The
minor rollers Q and Q¹ are provided with spindles q and q¹ which extend through
the reverse obliquely set slots r in the end supporting brackets R. It is
necessary for the proper distribution of the ink that these minor rollers Q and Q¹
be given an endwise movement alternately and in order to provide for this I
secure on one of the ends of the spindle the grooved collars q² and q³.
To the bottom of the brackets R I secure a bar and pivoted at the free end
thereof the rocking bar ³, which is provided with upwardly extending pins
and (see dotted lines) which extend into the grooves of the collars q3 and 23
respectively. One end of the rocking arm has pivotally connected to it the
lever S, which is pivoted at s on the frame and has a pin or roller s¹ at the front
end, which extends into a cam groove t of the cam wheel T secured to the counter
shaft C (see Figs. 2 and 8).
By means of this peripheral cam groove of the cam wheel T, it will be seen
that the lever S is rocked on its pivot and its opposite end conveys a like rocking
motion to the rocking bar and consequently a reciprocating motion alternately
in opposite directions to the minor rollers.
U is an intermediate minor ink roller, which is supported in crotches on the
end of the arms V pivoted in the bracket at each end of the ink fountain. W is
the lowermost ink roller, which is in the fountain itself and upon which nor-
mally rests the intermediate roller U, which itself normally is free of the major
roller 0. X is the bottom plate of the fountain, which is supported at one edge
by the side of the fountain and at the opposite edge by a longitudinal bar and
set screws extending through the bars whereby such plate is adjusted to any
desired position in relation to the roller. The ink is held immediately above the
plate X. The roller U is provided with a spindle u upon which it rotates and the
roller W with a spindle w.
In order to provide for the turning of the bottom roller W in the fountain,
so as to feed the ink I provide on the end of the spindle w an arm having a
slot The upper end of the arm is provided with a cam projection and has
pivoted inside of the projection a dog 4, which normally engages with the ratchet
wheel secured on the spindle inside of the arm.
Y is a link connected at one end to the arm n secured to the shaft N and at the
opposite end having a holt extending through a slot of the arm v¹, the end of
the bolt being provided with a small handle y, whereby the position of the con-
nection of the link Y to the arm may be very quickly changed without the
necessity of using a wrench, so that the throw of the arm and consequently of
the pawl may be regulated to a nicety.
and
As the inking rollers are moved through the pivoted bar M and mechanism
hereinbefore described, it will be seen that upon every such swinging movement
the motion will be communicated through the arm n, link Y and arm
pawl and ratchet wheel to the ink roller, thereby serving to turn it inter-
mittently. The cam-shaped projection will also be raised, so as to pass beneath
the arm V and thereby intermittently raise the ink roller U journalled in the arm,
from contact with the lower roller into contact with the major roller 0, thereby
carrying the ink to the latter roller.
In order to adjust the bed-plate L to a nicety I provide at each end thereof the
wedge-shaped bars, which rest upon the inwardly projecting ribs a at the in-
terior of the frame and extend into corresponding grooves at the outer edges
of the bed-plate.
In order to adjust the bars I secure on the end a collar 12 within which ex-
tends the spindle which is provided with an ordinary annular groove into
which extends a pin from the collar, this being an ordinary construction and
utilized in order to permit rotation of the spindle.
:
The spindle, is threaded at the outer end and provided with a hand wheel

page_text: and a locking hand wheel 5 and by means of the hand wheel the bed plate L
may be raised and lowered as desired and with a very fine adjustment so that the
impression may be regulated to a nicety.
The feeding table D is provided with gauge fingers Z held on the cross rod z,
which is bent at the end into arms z¹ pivoted at 22 at each side of the table upon
the brackets 23. A rod supported in suitable guides extends underneath
the front end of the arm and downwardly as shown being bent at the lower end,
so as to extend over the cam 26 secured on the counter shaft C. The cam 26 is
provided with a drop 27. The spring 28 rests upon the front end of the arms z¹
at the top. It will thus be seen that as the shaft C and cam revolve in the direc-
tion indicated by arrow the gauge fingers will be forced down so as to stop the
paper and when the end of the rod falls over the drop 27 will permit of the paper
being grasped by the gripping fingers of the cylinder E, the connection of which
I shall presently describe as the gauge fingers are then raised.
I have herein before described that the shaft F is journalled at each end in the
eccentric sleeves f in the standard G. Such standard G slides upon the ways G¹.
I shall now describe the manner in which the paper is fed and wound upon the
cylinder preparatory to being printed and carried to the delivery gripping fingers,
whereby it is removed on to the delivery table shown in dotted lines at the left
hand side of Fig. 2. The cylinder E is a hollow cylinder having ends secured
to the shaft F and is provided with a longitudinal opening e extending from end
to end thereof and end slots e¹ and e. El is the gripping bar, which is provided
with a series of gripping fingers curved in form and having the edge normally
resting and extending over the edge of the opening e. The cylinder E is shown
in its normal position in proximity to the table. The gripping bar El is provided
at each end with the pins e and e, which extend through the slots e¹ and e2
respectively. e5 and e6 are arms pivoted outside the ends of the cylinder E upon
the rod e', which extends through the cylinder. The pins e³ and et extend through
the slots and e in the arms e5 and e6.
It will be noticed that both arms are substantially L-shaped and that the
arm e is provided with an extension from which projects outwardly a pin elo.
8 is an arm pivoted on the cross 9 and provided with an inwardly extending end 10
which is designed to co-act in the manner hereinafter described with the pin e³.
11 is an arm secured to the same rod and provided with an inclined end 12,
which is reversely inclined as to direction of rotation to that of the inclined
end 10.
The gauging fingers Z hereinbefore described are so timed to operate to
raise, to allow of the sheet to be grasped when the cylinder E revolves around
into the position shown in full lines in Figs. 1, 2, 3 and 4, in order to connect the
sheet to the cylinder that it may be wound around the same and printed as the
cylinder traverses from the feed table to the delivery table. The gripping
fingers, therefore, have to be raised in order to. allow the edge of the sheet fed
to extend beneath them so that the fingers may be dropped down upon the edge
of the sheet. To raise the fingers and to allow of them to drop the mechanism
herein before described it utilized, which operates as follows.
As the cylinder continues to rotate in the direction indicated by arrow and
approaches the feed table the pin e¹0 on the end of the arm e mounts the inclined
end 12 of the arm 11, thereby throwing the pins e³ and et on the ends of the
gripping bars and extending through the slots in the arms e and ef upwardly,
thus causing the grinning fingers to raise from the cylinder and pass over the
edge of the sheet. When the pin e¹0 has passed over the inclined end 12, the
arme drops, thereby allowing the pins and e4 to recede in their respective
slots et ande and the gripping fingers to drop upon the edge of the sheet.
At this juncture the cylinder starts to rotate in the opposite direction to that
indicated by arrow in Figs. 5 and 5b carrying with it the sheet of paper from the
feeding table, which winds around the cylinder until the cylinder has made one
revolution in approaching the opposite end of the bed. At this juncture the

page_text: pin 3 in the slot will strike and rise upon the inclined end of the arm 8 and mount
into the position shown in Fig. 5ª and then drop. The cylinder still continues
to revolve until it reaches the limit of its stroke. When the pins and e
have raised as hereinbefore described, it necessarily follows that the gripping
fingers have also raised and release this edge of the sheet and the gripping
fingers in passing around leave such edge of the sheet free as far as they are con-
cerned, but to be grasped by the delivery fingers, which I shall presently describe.
When the cylinder has reached the limit of its stroke as indicated the pin e
passes underneath the inclined end 10 of the arm 8 and consequently does not
effect the gripping bar, and the cylinder finally reaches the forward limit of its
stroke in proximity to the feed table whereupon the same operation is repeated
continuously during the process of printing.
In order to ensure of the gripping fingers dropping after being released upon
each raising I provide a pair of helical springs 13 extending over the outer side
of the gripping bar and secured at the opposite end to the shaft. As the cylinder
rotates and arrives at the position shown in dotted lines in Fig. 2, it is necessary
to hold the sheet up away from the periphery of the cylinder in order that such
sheet may be grasped by the delivery fingers, and in order to allow of this I
pro-
vide a cross bar 14 with upwardly extending fingers 15 and downwardly extending
arms 16 at the end, which project through the bottom of the cylinder and are
designed to come in contact with the track, so as to raise the fingers at this
juncture and consequently the sheet. It may be stated that I of course arrange
these fingers directly underneath the gripping fingers as otherwise the sheet
would be punctured.
In order to deliver the sheet when it has been brought by the cylinder and
gripping fingers forward into proximity with the end of the bed of the machine
and released by such gripping fingers, I provide the following mechanism. 17 is
a rock-shaft secured in the bracket extensions A¹ of the frame. 18 are arms
secured to the ends of the rock shaft and extending normally above the level of
the delivery table in an oblique direction as indicated. 19 is a cross rod con-
necting the upper ends of the arms 18. 20 is the lower gripping bar, which is
provided with a series of fingers 21 and the journal rings 22, one of which is
provided with a projection 23, which is designed to come in contact with a pro-
jection 24 on the collar 25 to limit the fall of the fingers. 26 is the upper
gripping bar provided with a series of fingers 27 and journalled on the rod 19
by the end rings 28. 29 is a spring encircling the rod 19 and secured at one
end to same and having the opposite end extending over the gripping bar 26,
so as to have a normal tendency to force the gripping fingers 27 downwardly
30 is a spring on the rod 19 secured at one end thereto and having the opposite
end extending under the gripping bar 20, the normal tendency of the spring
being to force the gripping bar and the fingers 21 thereof upwardly. 27 and 211
are the end fingers, which are provided with laterally extending pins 272 and
21 respectively. 31 is a rod connected to the finger 21 and extending down in
suitable bearings opposite the arm 18, the lower end being bent and extending
under a pin 32. When the arms 18 are being brought forward to grip the edge
of the sheet by the mechanism as hereinafter described the lower bent end of the
arm 31 is free from the pin 32, but when the upper end of the arm has reached
the limit of its rearward stroke, the bent end of the rod 31 contacts with the pin 32
thereby pulling down the finger 21¹ and releasing the sheet and allowing it to
drop upon the delivery table. The arms 18 are connected by the rods 33 to the
lower end of the lever 34, which is pivoted at the top at 35 on the frame and is
provided intermediately with a roller 36, which works in a cam groove 37 in the
opposite. gear wheel C. The shape of this cam is such that the arms 18 are
caused to rest for a considerable period of the rotation of the wheel C, which
period is that occupied by the traversing of the cylinder from the point shown in
dotted lines to the feeding table and back again to such point. The remaining
portion of the cam operates upon the roller 26, so as to bring the sheet delivery

page_text: fingers towards the cylinder when it reaches the dotted position and then bring
it back again.
The shape of the cam 37, however, is such that the delivery fingers travel at a
uniform rate with the cylinder to the extreme end of the rearward movement of
such cylinder, or during the period that the gripping fingers are removing the
sheet from the cylinder.
It will be seen that the normal tendency of the springs 29 and 30 is to keep
the fingers 21 and 27 close against each other and it is essential that a means be
provided to open the fingers to grasp the sheet as well as to open the fingers to
release the sheet.
In order to effect this it will be noticed that I provide a separating cam 38
attached to or forming part of the supporting rollers 39, which run on the upper
tracks G. These rollers 39 at each end, as the cylinder and the shaft thereof
revolve, of course necessarily support the cylinder during its movement across
the bed of type and the cam 38 is so arranged and timed, that when the gripping
fingers meet the cylinder, this cam 38 will pass between the pins 212 and 272,
thereby separating the fingers and allowing them to straddle the edge of the paper.
As soon as the cam has passed between the pins 272 and 212 the fingers 27 and 21
are forced by their springs together, so that the edge of the sheet is securely
gripped whereupon it is carried away by the rearward movement of the sheet
delivery device hereinbefore described.
I find it preferable to provide a pressure roller near each end of the cylinder,
which is designed to press against the edge of the printed sheet of paper and
prevent it from falling back from the cylinder during the period between when
the edge of the sheet is loosened by the gripping fingers on the cylinder and the
time it is being grasped by the sheet delivery gripping fingers. These rollers
are secured on the ends of the arms g¹ pivoted on the bearing standard G and
are held up to the cylinder by the springs g².
to
It will be noticed as hereinbefore described that the spindle F of the cylinder
is supported at the ends in the eccentric collars or sleeves f in the bearing
standards G. It is necessary in the backward movement of the cylinder
after having brought the paper over the type to receive the impression,
to raise such cylinder in order to escape the type. In order
effect this I provide projecting arms 40 having lateral extensions 41 through
which extends set screw 42. Upon one lateral extension 41 is formed a bear-
ing 43, which receives the curved end of the rod 44, which extends through the
guiding lug 45 on the side of the machine and is provided with an end stop 46.
As the cylinder is caused to move towards the delivery end of the bed after the
printing has been effected the stop 46 coming in contact with the lug 45 pulls
back upon the arm 40, thereby turning the sleeve or collar in its bearing in
the standards G, so that the long radius of the eccentric is lowermost, thereby
raising the cylinder in its movement clear of the bed in which position it will
remain as the retrograde movement is being effected. At near the limit of the
retrograde movement, however, the arms 40, which are now in a substantially
vertical position strike against the pivoted rocking detents 47, which are held
rigidly against the pins 48 and thereby knock the arm 40 backward again into
its initial position shown in Figs. 1 and 6. This operation is repeated upon each
reciprocating movement of the cylinder.
In order to provide a means whereby should one sheet be missed through the
fault of the attendant of the machine, I provide the following simple device, or
what is technically known as the throw off, in order to raise the cylinder clear
of the type and prevent it printing on the tympan or pad on the cylinder.
49 are catches secured on each end of the rod 50, which is suitably pivoted in
the side bars of the feed table as indicated. The catch 49 is provided with a
weighted handle 51 and the rear end of the catch is designed to be brought into
engagement with the notch 52 in the upper end of the rocking detent 47 when a
sheet has been missed. The result is that the arm. 53. forming part of the

page_text: eccentric sleeves at each end of the spinare comes in contact with the bottom
end of such rocking detents and thereby as such rocking detents are locked the
arms 53 are turned downwardly as to direction of movement of the cylinder, so
as to throw the longer radius of the eccentric sleeves f lowermost and thereby
raise the cylinder above the height of the bed, so that such cylinder when no
sheet is on it will pass in such elevated position backwards and forwards to its
initial position again without any printing being effected.
It is of course to be understood that when the arm 53 is tilted it will be tilted
sufficiently, so that it will pass under the rocking detent. As the arm 53 moves
with the cylinder in its movement to the feeding table again it will again pass
under the lower end of the rocking detent at each side, but the arm 40, which is
now raised will strike against the now locked rocking detent whereupon the
arm 40 on each side will be lowered into its initial position ready for the next
forward movement of the cylinder, which is thereby lowered ready to give the
impression. The catch 49 may be of course raised from engagement with the
notch at the top of the rocking detent at any time after the cylinder has passed
such detent in its movment toward the delivery table.
