Improvements in and relating to Printing Machines.
I, FRANCIS MEISEL, of No. 86 Stoughton Street, in the City of Boston, County
of Suffolk, and State of Massachusetts, United States of America, Factory
Manager, 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:-
My invention has for its object to provide a printing machine in which the web
may be cut into sheets of various lengths and automatically placed against the
front and side gages so that the imprint will be produced in the same position on
each sheet, whereby if it should be necessary to again feed in the sheet by hand for
additional imprints, perfect register will be produced.
To this end my invention consists in certain novel features, combinations of parts
and details of construction as will be hereinafter fully set forth aud specifically
pointed out in the claims. My invention also has for its object to provide a simple
and effective mechanism for giving endwise motion to the vibrator-rolls of the
inking apparatus of the form or printing cylinders.
To this end my invention consists in operating the rocker-levers from which
end wise motion is transmitted to the vibrator-rolls, by means of oscillating bevel-
wheels lying in a plane parallel with the plane in which the end of the printing
cylinder lies and receiving motion through suitable connections from the driving
shaft, said bevel gears meshing with sector gears on said rocker-levers, whereby all
the vibrator-rolls throughout the machine are simultaneously operated in a simple
and convenient manner from a single shaft as hereinafter more particularly
described.

In the said drawings A, represents the framework of the machine, in suitable
bearings in which runs the driving shaft B, carrying at one end outside the frame-
work a driving pulley C, Figure 1, and a pinion, shown dotted, which meshes with the
gear a, on the shaft of one of the form cylinders from which gear a, motion is
communicated through the medium of suitable gears to various other cylinders,
rolls and moving parts of the machine to be hereinafter described.
D represents the first or upper form cylinder and E the second or perfecting
form cylinder to which the type forms or plates are secured in the usual manner,
and G, represents the first impression cylinder which co-operates with the cylinder D ;
and H, represents the second or perfecting impression cylinder which co-operates
with the cylinder E as shown in Figure 1.
The web b, of paper to be cut into sheets is drawn from a roll I, which is mounted
on a shaft 15, the journals of which rest in suitable bearings in a carriage F, sliding
on horizontal ways at the end of the framework and operated by a rack and
pinion 16, 17, as shown in Figures 1 and 3, said web b, being unwound from the roll by
a pair of feed-rolls c, d, the shaft of the roll c, carrying a gear 18, which is driven
by a train of intermediate gears receiving motion from the driving shaft. is a
stationary cutter blade or knife, inclined at an angle as shown in Figures 1 and 2,
said cutter blade being made adjustable in a stock or support 19, secured to the
carriage F, by means of screws 29 and 30, and f is a rotary cutter-blade co-operating
with the stationary blade e, and secured to a cylinder K, the axis of which is
parallel with the edge of the stationary cutter-blade e, The shafts of the feed-
e,
rolls c, d, and cylinder K, run in bearings in supports rising from the carriage F,
as shown in Figures 1 and 3. In order to produce a shearing cut, the rotary
cutter-blade is inclined to the axis of the cylinder K, and the inclination of both
of the cutter-blades as described, causes the web of paper while in motion to be cut
at right angles to the direction of its length. The cylinder K, is also provided
with longitudinal lags 28, arranged around its circumference, said cylinder being
rotated by a gear 31, on its shaft meshing with and being driven by one of a train
of gears connected with the driving shaft.
As the web of paper is drawn into the machine by the feed-rolls c, d, it passes
between the stationary cutter-blade e, and the rotating cylinder K, the lags 28, of
which by their frictional or rubbing contact with the paper, serve to carry it
forward and deposit it upon the lower tapes g, which run over pulleys h, at the
same surface speed as the impression cylinder, and co-operate with the upper tapes i,
running over pulleys k; and as soon as the sheet is severed from the web by the cutters,
it is carried forward between said tapes g, i, over a table L, which is provided with
a series of upwardly projecting pins or projections m, and is made movable vertically
and also in a forward and lateral direction by mechanisin to be presently described.
As soon as the sheet has been carried into a position over the table L, and just
before it reaches the front gages n, the said table is slightly raised which causes its
pins m, to lift the sheet clear of the lower tapes g, as shown clearly in Figure 3,
but not sufficiently high to come into contact with the upper tapes i, which merely
prevent the sheet from being raised by the air, immediately after which the table
is moved forward and simultaneously swung to one side, the said combined forward
and lateral movements of the table causing the sheet supported on the pins m, to
be brought with absolute certainty squarely and evenly against the front and side

page_text: gages n, p, before it is seized by the grippers g, of the first impression cylinder G,
whereby if the sheet should be afterward fed in by hand to the same or another
machine for a second impression on the same or upon the opposite side, perfect
register would be insured which would not be the case if the tapes were relied upon
to bring the sheet up to the gages.
The mechanism by which the various movements are given to the table L, will
now be described, reference being had particularly to Figures 3, 9, 10 and 11.
Near each of the four corners of the table L, on the under side is a boss or
projection 33, provided with a vertical stud 34, Figure 11, which enters a hole in a
link 35, which is pivoted to swing on the upper end of a short bar 36, which is fitted
to slide vertically in a bearing in a lug 37 projecting from the inside of the
framework.
The supporting bar 36, is provided with a pin 38, which projects out therefrom
through a slot in the lug 37, and carries at its outer end an antifriction roll 39,
fitting within a cam-slot 32, in a lever 40, fulcrumed at 41, the two levers on the
same side of the table being connected by a rod 42, and one of said levers having
pivoted to it a short rod 43, jointed to a liuk 44, pivoted to the framework, and on
the pin which connects the rod 43 with the link 44, is a cam-roll which is acted
upon by a cam 45, on a shaft 46, connected by gears with the driving shaft,
whereby as said cam 45, is rotated, the levers 40, are rocked to raise and lower
the table L, at the proper times. The two levers 40, on the opposite side of
the table L, are actuated by similar mechanism receiving motion from another
cam 45, at the opposite end of the shaft 46, as shown in Figure 2. To an arm 47,
projecting outward from one of the links 35, as shown in Figure 2, is jointed a
rod 48, which is pivoted at its opposite end to a lever 49, carrying a cam-roll
which is acted upon by a grooved cam 63, secured to the shaft. 46, whereby as
soon as the table L, has been slightly raised to lift the sheet off the tapes g,
it is swung in a horizontal plane on its four pivoted links 35 which gives it a
forward and lateral movement thus bringing the sheet resting on the pins m,
squarely and evenly against both of the front gages n, n, and the adjustable side
gage p, as before described, the table being returned to its normal position after
the sheet has been seized and carried forward by the cylinder-grippers q, which
are opened and closed by mechanism hereinafter described.
The front gages n,
are mounted as usual upon a rock-sbaft 50, which is actuated to lift the gages.
at the proper time by a rod 51, operated by suitable can and lever connections,
shown dotted in Figure 3.
The length of the. sheet severed from the web by the cutters can be varied
by changing the surface velocity of the feed-rolls with relation to that of the
rotary cutter-cylinder. K. This is effected by the employment of a chain-wheel M,
Figures 2 and 3, which is removably secured to the shaft 46, which also carries
a gear 52, which gives motion through two intermediate gears 53, 54, to the
gear 31, on the shaft of the cutter-cylinder K.
The change-wheel M, meshes with an intermediate gear 56, rotating on a
stud 57, mounted upon a supporting arm 58, swinging on a shaft 59, and held in
place when adjusted, by a clamping screw 60, passing through a slot 61, said
gear 56, transmitting motion through intermediate gears 62, 63, to the gear 18,
on the shaft of the lower feed-roll b, and thus by removing the change-wheel M,
and substituting another having a different number of teeth, the speed of the
feed-rolls with relation to that of the cutter-cylinder can be varied as desired
to change the length of the sheet cut from the web.
As soon as the sheet is, seized by the grippers q, of the first impression cylinder G,
said grippers having been opened and closed for this purpose by mechanism
bereinafter described, it is carried between the cylinder G, and the first form-
cylinder D, receiving an impression therefrom, after which, if it is not to receive.
a second or perfecting impression on the opposite side, it is carried around past a
wedge-shaped guide N, and between tapes 12 and the cylinder G, to the first
accumulating cylinder P, which is provided with a fly 66, which deposits the
1

page_text: sheets upon a table R, Figure 1, the grippers 9, being operated to release the
sheet at the instant that it is seized by the grippers 67, Figure 5, of the accumu-
lating cylinder P. The guide N, is formed by the angular points of a series of
bands r, which partially encircle the cylinder H, and are secured to suitable
supports, not shown.
The cylinder P, which accumulates a certain predetermined number of sheets
to be removed by a single operation of the fly 66, is of the ordinary well known
construction which forms no part of my present invention and will not be further
described.
The grippers 9, of the first impression cylinder G, are mounted on a rock-
shaft 70, to one end of which is secured a pinion 71, which meshes with a sector
gear 72, at the end of a lever 73, pivoted at 74, Figures and 5, to the end of
the cylinder G, said lever carrying a roll 68, which is acted upon by a cam Q,
having two removable portions secured to a stationary ring-shaped support 75,
attached to the frame A, and located opposite and close to the end of the
cylinder G, as shown in Figure 6. As the. cylinder G, revolves, the roll 68, is
brought into contact with the cam Q, thereby moving the lever 73, to open the
grippers to receive the sheets, against the resistance of a spiral spring 76,
encircling a rod 78, which is pivoted to the lever 73, its opposite end passing
through a guide lug or projection 80, said spring serving to close the grippers
on the sheets as they are fed against the front gages n by reason of the roll 68
passing out of contact with the cam Q at about the point Q*, Figures 4 and 5.
When the sheet is to be carried around by the cylinder G, and delivered to the
accumulating cylinder P, the central portion 81, of the cam Q, is removed and
the inclined portion 82, moved into the position shown in Figure 5, so that the
roll 68, will not come into contact with the cam until the end of the sheet is in a
position to be seized by the grippers 67, of the accumulating cylinder P; but
when the machine is to be used as a perfecting press and it is desired to have
the sheet pass under the guide N, and around between the second or perfecting
pair of form-cylinders E, H, the entire length of the cam Q, is used as shown
in Figure. 4, which causes the roll 68, to be brought into contact with the point
of the cam Q, to open the grippers q, just before the sheet reaches the angular
points of the bands r, which form the guide N, the front or leading end of the
sheet being then pushed out from the surface of the cylinder G, to cause it
to pass under the guide N, by an outward thrust of a series of pins 83,
Figure 4, commonly called "shoo fly" pins which are operated in a well known
manner by mechanism not shown. These "shoo fly" pins are intended to be
thrown out of action when the sheet is not to be delivered to the perfecting
impression cylinder H. The grippers 9, can thus be arranged to open at
different points by changing the cam Q, so that the sheet can be released at
the proper place to allow it to be seized by the grippers of the first accumu-
lating cylinder P, when a sheet is to be printed on one side only, or so that the
sheet can be released at a different place when the paper is to be printed upon
both sides.
The guide-bands r, which lie close to the cylinder H, leaving a space for the
passage of the sheet, are arranged to come opposite to the margins or spaces
between the several printed forms, and each of these bands is provided with a
series of apertures 84, as shown in Figure 8, through each of which projects
a guide-roll 85. The guide-rolls 85, are secured to shafts 86, extending across
the machine parallel with the axis of the cylinder H, and supported in bearings
in lugs 87, projecting from the bands r, each shaft carrying at one end a small
gear, not shown, which meshes with a large gear not shown, inside the framework,
whereby the rolls are rotated with the same surface velocity as the cylinder H,
and caused to carry the sheet by their friction thereon around said cylinder H, to
the form cylinder E, from which it receives a second impression upon the side
opposite to that first printed, after which it is carried by the rolls 85, to the second
accumulating cylinder S, Figure 1, similar to the cylinder P, first described, and

page_text: provided with grippers 88, operated at the proper time to seize the sheet, sail
cylinder S, being provided with a co-operating fly 89, which serves to remove the
sheets after the required number have been collectel on the cylinder an
deposit
them upon a suitable table similar to the table R, shown at the left hand side of
Figure 1.
The rolls 85, are employed to carry the sheet to the second form-cylinder ani
thence to the accumulating cylinder S, beyond, for the reason that it is impossible
to provide the second impression cylinder H, with grippers as they would interfere
with the offset-web T, which is operated in the usual manner by being unwound
from one roll and simultaneously wound up on another as shown in Figure 1. The
offset-web T, passes over a transverse bar w, Figures 1 and 4, preferably of
triangular shape in cross section as shown, and located between the accumulating
cylinder S, and the perfecting impression cylinder H, whereby a narrow throat is:
left for the passage of the web which then passes from the upper right hand eige
of said bar w, up around the guide a', preferably of roller form, located above.anl
to the left hand side of the guide-bar to, whereby the direction in which the offset.
web travels is abruptly changed at an angle to permit the sheet to be seized by the
grippers 88, which are ready to seize it as soon as its front edge is brought above
the upper edge of the guide-bar w, at the point where the offset-web passes off at.
an angle to the guide a', said web after leaving the guide a', passing directly to
the roll 9, upon which it is wound up.
When it is desired to feed in by hand for a second impression on the opposite
side, sheets that have been previously printed on one side only, a board can be
placed over the table L, upon suitable supports, in which case the sliding
carriage F, which supports the web, feed-rolls, cutters &c., is moved back out.
of the way so as not to interfere with the operation of feeding in the sheets by
hand.
It is obvious that any number of pairs of form and impression cylinders with
grippers can be added between the first and last pairs of cylinders and that
accumulating-cylinders can be attached to any or all of the pairs to take the sheet
away from the impression cylinder.
From the foregoing it will be seen that the above described machine can be very
advantageously used for very high class work and also for that of a lower gradle.
For very fine work the sheets can be taken from the web and rapidly printed on
one side only, as the machine can be run at a high speed, the sheets being afterwar.!
fed into the same or another machine by hand for a second or perfecting impression,
while if ordinary work is required the machine can be used as a perfecting press
and also run at a high speed, advantages not combined in any one machine with,
which I am acquainted.
I will now describe the mechanism for giving endwise motion to the vibrator-
rolls of the inking apparatus, reference being had to Figures 12, 13, 14 and 15..
Each of the form-cylinders D, E, is provided with the usual inking apparatus.
consisting of form-rollers, distributing cylinders, vibrator-rolls, etc., which are
rotated by suitable gears receiving motion from the gear of the shaft of the form-
cylinder. The shafts a² of the vibrator rolls A¹ are rotated by means of suitable
gears, and to these vibrator-rolls, end wise motion is given by mechanism which
will now be described. To the outer end of one of the shafts 6' of the machine,
which in the present case is connected with the shaft of one of the impression
cylinders by gears 62, 63, is secured outside the framework, a disk c¹ to a crank.
pin d' on which are pivoted two connecting rods e¹ e', the opposite ends of which
are respectively pivoted to two bevel-wheels B' B' mounted on studs 9' projecting.
from a casting C₁ bolted to the framework A, said studs being arranged in line.
with the axes of the form-cylinders, whereby as the disk c¹ is rotated an oscillating.
movement is imparted to said wheels B' B' which are provided at their peripheries.
with bevel-teeth h¹. These wheels are preferably provided with teeth at certain
portions only of their peripheries as shown, but the teeth may extend entirely
around the wheels if desired. If more than two form-cylinders are employed, the.

page_text: bevel-wheels B' B' will be caused to oscillate other similar bevel-wheels, one for
each additional form-cylinder, by means of connecting-rods; and in this manner
any desired number of similar bevel-wheels arranged around a printing machine
can be simultaneously oscillated from a single driving shaft.
Each bevel-wheel B¹ gives end wise motion to the several vibrator-rolls A' of the
inking apparatus of a single form-cylinder in the following manner. D' is a
double-ended rocker-lever which is pivoted on a stud projecting radially from the
casting in a plaue at right angles to the axis of the stud g' on which the bevel-
wheel B' oscillates, said rocker-lever being provided at the centre with a sector
bevel-gear meshing with the wheel B' as shown in Figs. 12 and 13, and said
rocker-lever being provided at its two opposite ends with oscillating projections n
which engage grooved disks pl secured to the ends of the shafts a² of a pair of
vibrator-rolls A' as shown in Fig. 13, which are thus reciprocated in the direction
of their length as the wheel B₁ is oscillated by the means described. E is another
rocker-lever which is also pivoted on a radial stud projecting from the casting C¹
at right angles to the study, said rocker-lever F1 being provided with a sector
gear g', Figures 12 and 14, also meshing with the teeth of the oscillating wheel B',
this lever E being connected by a rod rl with an arm 2, Figures 12 and 14,
secured to the end of a rocker-shaft s' supported in suitable bearings projecting
from brackets t¹ secured to the framework A. To this rocker-shaft s are secured
two short arms a³ a as shown in Figure 12, the arm a³, having an oscillating
projection a which engages a grooved disk w¹ at the end of another vibrator-roll,
and the arm a having a similar projection a' which engages a grooved disk on one
of another pair of vibrator-rolls connected to reciprocate in opposite directions by
a double-ended rocker-arm a°, so that as the shaft is rocked, the vibrator-rolls
connected therewith will be reciprocated simultaneously with the pair actuated by
the rocker-lever D' as previously described; and in this manner all the vibrator-
rolls throughout the machine are simultaneously reciprocated in the direction of
their length as the disk c¹ is rotated.
I do not wish to limit myself to the number of vibrator-rolls operated from a
single oscillating bevel-wheel B', as the number may be increased or diminished
without departing from the spirit of my invention.
If more rolls are required, as many rocker levers may be arranged around and
to mesh with a single bevel-wheel B' as its circumference will properly accommodate,
the casting C being provided with a radial stud similar to those above described
for each rocker-lever; or each rocker-lever may be made to operate more vibrator-
rolls by means of suitable connections similar to those shown and described.

wheel is oscillated, substantially as set forth.
17. In a printing machine, the combination with the printing cylinder, of a pair
of vibrator-rolls and their shafts, the latter provided at their ends with grooved
disks, an oscillating toothed bevel-wheel lying in a plane parallel with the plane in
which the end of the printing cylinder lies and means for actuating the same,
a double-ended centrally pivoted rocker-lever having projections engaging the
grooved disks of the shafts of the vibrator-rolls, and provided with a sector-gear
meshing with said oscillating wheel, whereby the vibrator-rolls are reciprocated
in the direction of their length as the bevel wheel is oscillated, substantially as
described.
18. In a printing machine, the combination with the several sets of vibrator-rolls,
of a series of oscillating toothed bevel-wheels and suitable connections, whereby
motion is transmitted to all of said bevel-wheels from a single shaft, rocker-levers
provided with sector-gears meshing with said oscillating bevel-wheels, and suitable
connections between said rocker-levers and the shafts of the vibrator-rolls, whereby
the latter are reciprocated in the direction of their length as the bevel-wheels are
oscillated, substantially as set forth.
