Year: 1884

page_text: I, HENRY HARRIS LAKE, of the firm of Haseltine, Lake, & Co, Patent Agents,
Southampton Buildings, London, in the County of Middlesex do hereby declare
the nature of said Invention for "IMPROVEMENTS IN PRINTING MACHINES
as follows:
"
to be
This Invention relates to printing machine of that class wherein two or more
pairs of type and impression cylinders, each provided with separate inking
apparatus, are employed, and is applicable more particularly to continuous-web
printing machines but is in part applicable to machines for printing sheets.
In a continuous-web printing machine it is of importance that the cylinders of
the several pairs should be driven at exactly uniform and unvarying speeds, and
that the driving mechanism should be of such a nature as to provide for the
adjustment of each pair of cylinders in a lateral direction relatively to the other
pair or pairs.
The said Invention consists partly in the combination with two or more pairs of
type and impression cylinders, adjustable laterally towards and from each other,
of spur wheels on the shafts of the cylinders, and endless spur-toothed racks
engaging with, but supported independently of, the said spur-wheels, and serving
by their movement to impart motion to the said spur wheels and cylinders.
It also partly consists in the combination with two or more pairs of type and
impression cylinders, adjustable laterally towards and from each other, the type
cylinder of each pair being uppermost, of spur-wheels on the shafts of the type
cylinders, and endless spur-toothed driving racks engaging with, but supported
independently of, the said spur-wheels, and composed of rigid sections having teeth
upon their outer faces and pivoted together.
It also partly consists in the combination with two or more pairs of type and
impression cylinders, of spur wheels upon the shafts of the cylinders, endless spur-
toothed driving racks gearing with the said wheels, and supporting wheels for the
.

page_text: said racks, made separate from and entirely independent of the spur-wheels with
which the racks engage, and arranged outside of, and beyond, the said cylinders
at the ends of the machine.
It also partly consists in the combination of pairs of type and impression
cylinders, spur wheels on the shafts of the said cylinders, endless spur toothed
driving racks engaging with and driving the said spur-wheels; polygonal
supporting-wheels around which the said racks pass, and pinions engaging with,
and serving to operate, the said racks.
It also partly consists in the combination with two or more pairs of type and
impression cylinders, of spur-wheels on the shafts of the cylinders, spur toothed
racks engaging with the said spur-wheels, grippers attached to the said racks, and
supporting wheels around which the said racks pass and which are made separate
from, and independent of, the said spur-wheels and are arranged outside of, or
beyond, the said cylinders.
It also partly consists in the combination with two or more pairs of type and
impression cylinders, of spur wheels on the shafts of the said cylinders, endless
spur-toothed driving racks engaging with the said wheels, other wheels for carrying
the said racks, and slideways or supports for the racks opposite their points of
engagement with said spur wheels. The said slideways serving to hold the racks
uniformly in engagement with the spur-wheels and being preferably grooved,
flanged, or equivalently constructed to hold and guide the racks laterally as well as
vertically.
It also partly consists in the combination with pairs of type and impression
cylinders spur-wheels on the shafts of the cylinders, endless spur-toothed racks
gearing with the said spur-wheels, other wheels for carrying the said racks, and
slideways wherein the said racks move, of grippers attached to the inner sides of
the said racks and stationary cams past which the said grippers are carried by the
racks and by which the grippers are opened.
It also partly consists in the combination with a pair of type and impression
cylinders which are fixed laterally, of auxiliary side frames and means for adjusting
them in the said main side frames towards and from the said cylinders, and pairs
of type and impression cylinders journalled in the said auxiliary frames, whereby
provision is afforded for accurately adjusting the pairs of cylinders which are
journalled in the said auxiliary side frames, relatively to the pair of cylinders
which are journalled in the said main side frames.
It also partly consists in the combination with a pair of type and impression
cylinders, of a main frame wherein they are journalled, an inking apparatus for
the said type cylinder, a carriage wherein the inking apparatus is supported, and
tracks or ways whereon the said carriage may be moved in a direction lengthwise
of the cylinder.
In a machine wherein three pairs of type and impression cylinders are used, the
inking apparatus for the first and last pairs of cylinders can be moved laterally to
enable the type cylinders of the said first and last pairs to be removed and other
type cylinders substituted for them; but where there is little space between the
pairs of cylinders, the inking apparatus of the middle pair of cylinders cannot be
moved laterally because of lack of room. The combination last above described
provides for removing the inking apparatus of the middle pair of cylinders by a
movement in the direction of the length of the said cylinders."
After the continuous web has received impressions from the two or more pairs
of cylinders it is commonly cut off into sheets as it issues from the machine; the
Invention therefore further partly consists in the combination with two or more
pairs of type and impression cylinders for printing upon a continuous web, of
devices for cutting off sheets from the web after printing, tapes or other carriers
moving at the same speed as the web and serving to take the sheets as they are
cut-off, and a cylinder or wheels, provided with delivery grippers, and geared so
that the said grippers will move at a quicker speed than the tapes or other carriors

page_text: first mentioned, thus serving to deliver the sheets with an accelerated movement.
The advantages of this accelerated movement are that it makes a break or
separation between the sheets cut off, and enables the delivery grippers carried by
the aforesaid cylinder or wheels to get into position at the proper times to take the
sheets successively.
In carrying the said Invention into practice I provide main stationary side
frames for the machine which frames may be of any suitable form, and connected
by suitably arranged stretchers.
A type cylinder and an impression cylinder are journalled in suitable bearings
in the side frames. These bearings are fixed, that is they are not adjustable
laterally, although the box of the type or upper cylinder may be adjusted upwards
and downwards in the usual manner.
On each side of the said pair of cylinders are arranged other type and impression
cylinders similar to the first pair but instead of being journalled in the main frames
they are journalled in auxiliary frames which are mounted on slides, and are
capable of adjustment independently of each other towards and from the centre of
the machine, that is towards and from the central or middle cylinders.
Each auxiliary side frame has upon it a nut, and a screw is mounted in fixed
bearings so that it may not move lengthwise, and engages with the said nut.
Upon the screw, is secured a worm wheel, with which engages a worm or screw.
The two worms or screws on opposite sides of the machine are mounted on the
same shaft which may be turned by a wrench applied to either end. By turning
the said shaft, both worms or screws will be operated and the auxiliary frames at
opposite sides advanced together. By this means I may adjust each outer pair of
cylinders independently of the other pair towards and from the middle pair of
cylinders and the worm wheels and screws employed for the purpose serve also to
hold the auxiliary frames and the cylinders carried thereby, in place after their
adjustment.
This combination of the middle pair of cylinders, which are non-adjustable
laterally, and one or more pairs of outer cylinders on each side thereof, adjustable
towards and from the middle cylinders, forms an important feature of this
Invention, but so far as some other features of the Invention are concerned I may
use two or more pairs of cylinders, each pair being adjustable laterally relatively
to the other or I may use two or more pairs of non-adjustable cylinders.
It is often desired in machines of this class to remove the type cylinder and
substitute another, larger or smaller, as may be necessary. The upper parts or
caps of the housings which are formed in the side frames must therefore be
removable. I make the bearings of all the type cylinders, of solid blocks, and I
vary the distance between the lower surfaces of these blocks and the hearings or
holes therein to suit cylinders of different diameters; the blocks always are
intended to rest solidly in the bottom of their housings. For example, with a
cylinder of large diameter the bearings or holes in its blocks would be at
considerable distance from the bottom thereof, while if the cylinder be of lesser
diameter, the bearings or holes will be nearer the bottom thereof.
The cylinders of each pair are provided with the usual bearers or bearing rolls,
which roll together and preserve the surfaces of the cylinders against injury and
are geared together by gear wheels.
The bearers or bearing rolls, consist of cylindric portions or surfaces inside of
and close to the gear wheels. They may be formed by circular flanges on the
inner sides of the gear wheels, of the same diameter as the pitch diameter of the
said wheels.
In order to rotate the cylinders, upon the shaft of each type cylinder, and near
the ends thereof, are screwed spur wheels or gears through which a positive and
uniform motion is transmitted to the said type cylinders, and through the gear
wheels to the impression cylinders.

page_text: At each side of the machine and in the same vertical planes as the spur-wheels
or gears are endless spur-toothed racks which intermesh with and drive the said
wheels or gears and through them the cylinders.
Each endless rack is composed of rigid sections, jointed or pivoted together and
the teeth are so spaced or formed that the space at the joint, between the end teeth
of any two rack-sections, is a proper tooth space, aud of the same size as the spaces
in each individual section. These endless racks are mounted on wheels which are
of polygonal shape or have polygonal seats in which the racks fit, and both wheels
are adapted to rotate freely as the racks are moved over and around them.
The shafts of the polygonal wheels are journalled in the fixed or main side
frames and are placed at such distance apart as to preserve the proper tension of
the racks. It might be desirable to make the bearings of one shaft slightly
adjustable to enable the racks to be tightened if their joints or connecting pivots
become much worn.
The racks are in gear with all the type cylinders and transmit an uniform and
steady motion to them; and the transmission of such motion is not interfered with
in any way by the adjustment of the cylinders towards and from each other.
It is also evident that the adjustment of the cylinders will not in any way
affect the tension of the endless racks, as would be the case if the polygonal wheels
were mounted on the shafts of the type cylinders at the opposite ends of the
machine.
The endless racks are very strong, they transmit a smooth and uniform motion
to the cylinders, the wheels into which they gear for driving are entirely separate
from, and independent of, the wheels on which they are supported, the spur wheels
rest upon their upper and exterior surfaces, and the cylinders can be lifted out
without disconnecting the racks from the wheels which carry them, and they are
altogether more reliable and desirable for the purpose than are chains or bands,
such as have been used heretofore.
The racks may be driven by imparting a positive motion to the polygonal wheels
at one end of the machine, but I prefer to drive them by pinions or spur wheels,
gearing into their faces.
A shaft extends transversely across the machine and is provided with pinions or
spur wheels which engage with the racks. Upon the said shaft is also secured a
driving pulley for the reception of a driving belt.
It is very essential that the racks should be supported opposite the points of
their engagement with the spur wheels so that they will gear into the said wheels
to their pitch line and avoid slip. Below the upper or driving portion of each rack
I arrange a rest, slideway or support, therefor, which is supported upon brackets,
projecting from the main frames. These rests or slideways extend from one end to
the other of the machine; past all the spur wheels and the driving pinions, and
form adequate supports for the racks and prevent any tendency of the racks to ride
over or move out of gear with the gear wheels. The slideways have flanges at the
sides, or recessed bearing surfaces, and the racks are thereby held in place laterally
as well as vertically. The whole lower or interior surface of the racks may slide on
the slideways or I may provide them with rollers at the joints.
The racks not only serve as drivers for the type cylinders but they also serve as
carriers for the continuous web of paper, which is taken from a roll.
Upon the inner sides of the racks are grippers which grasp the web as they
arrive at the upper or operative part of the racks and are released therefrom as
they reach the opposite end of the machine.
Each gripper is composed of a fixed or rigid jaw, and a pivoted movable jaw,
having a depending tail. Coiled upon the pin by which the movable jaw is pivoted
to the fixed or rigid jaw, is a spring or springs which tends or tend to hold the
movable jaw tightly closed on the fixed or rigid jaw.
At the end of the machine at which the paper roll is located are stationary cams.
As the grippers are brought by the racks opposite these cams their tails are acted

page_text: on by the cams, and their movable jaws are opened to take in the web and are at
once closed by the action of the springs.
At the opposite end of the machine are other stationary cams, and as the grippers
reach these cams their movable jaws are opened and the web released from them.
Any number of grippers may be employed in each rack.
Each of the outer cylinders has an inking apparatus which is supported in a
carriage that is movable towards and from the cylinder upon ways formed on the
main frames.
If it is desired to remove either outer cylinder from its bearings, all that is
necessary is to raise the inking rollers, and then move the carriage away from the
cylinder.
The middle type cylinder is likewise provided with an inking apparatus,
supported in a carriage but this carriage, instead of being movable transversely to
the cylinder is movable lengthwise thereof, along tracks on ways, extending
horizontally from the side of the machine. When it is desired to remove the
middle cylinder from its bearings, the inking rollers are lifted or swung upward,
and the carriage is then moved horizontally away from the cylinder.
In a machine of this class it is very advantageous to have the inking apparatus
of the middle cylinder movable lengthwise of the cylinder, as there is not room
between the cylinders to admit of its being moved transversely to the length of the
cylinder, or lengthwise of the machine. If more than three pairs of cylinders are
employed the carriages carrying the inking apparatus of all cylinders except the
end ones will be made capable of movement in the same direction as the carriage.
In order to transmit motion to the inking apparatus I arrange upon the side of
the machine a horizontal shaft which is rotated by bevel gear wheels from the
driving shaft. Connected with each inking apparatus is a vertical shaft which is
connected with and rotates from the horizontal shaft by pairs of bevel gear wheels.
The vertical shafts are fitted to bearings on the carriages and are movable with the
said carriages towards and from the middle cylinder.
Supported on the carriage of the middle cylinder is a second vertical shaft which
receives motion from the horizontal shaft through bevel gear wheels; and in order
to enable the carriage to be moved as described, the wheel on the horizontal shaft
should be fitted thereto with a feather, so that it may be moved out of engagement
with its fellow wheel when the carriage is to be shifted.
Although I have only described the racks as engaging with spur wheels upon the
type cylinders such wheels might be placed on the shafts of the impression cylinders
and the said impression cylinders, would then transmit motion through gear wheels,
to the type cylinders.
To cut off and deliver the sheets I arrange at the delivery end of the machine
rolls between which the continuous web of paper passes and which receive motion
from a shaft. Just in advance of the rolls is a bed or support over which the web
passes and to which is fixed a shear blade. A movable shear blade is carried by a
cylinder or drum which receives rotary motion from the said shaft. At each
revolution of the cylinder or drum a sheet is severed from the web.
In advance of the shear blades are upper and lower series of tapes which are
mounted on wheels, and which are operated by a shaft and suitable gearing from
the shaft of the cylinder or drum. The tapes are moved at the same speed as the
continuous web of paper and carry forward the sheets between them.
Any other suitable mechanism may be used for cutting off and delivering the
sheets. A rotary cylinder or series of wheels is provided having delivery grippers.
This cylinder is geared to move at such a speed that its surface velocity will be
greater than the speed of movement of the continuous web and the tapes and hence
when the sheets are taken by the grippers from the tapes they will be delivered
with an accelerated movement.
If the cylinder has two sets of delivery grippers, it should make a half revolution
at each delivery. The grippers may be acted upon by a stationary cam over which

page_text: they are carried, in order to open them at the proper time to deliver the sheets into
a box and may be held open by the said cam until they come to a position to close
on the sheet presented to them by the tapes.
Any mechanism may be employed for rotating the cylinder which will move the
grippers at a quicker speed than the tapes.
In some cases it may be desirable to slit or divide the sheets lengthwise after
they are cut off by the shear blades and rotary discs or cutters may be employed
for such purpose.

page_text: I HENRY HARRIS LAKE, of the firm of Haseltine, Lake, & Co, Patent Agents,
Southampton Buildings, in the County of Middlesex, do hereby declare the nature
of my Invention for "IMPROVEMENTS IN PRINTING MACHINES" and in what
manner the same is to be performed, to be particularly described and ascertained in
5 and by the following statement :-
This Invention relates to printing machines of that class wherein two or more
pairs of type and impression cylinders, each provided with separate inking
apparatus are employed and is applicable more particularly to continuous-web
printing machines, but is in part applicable to machines for printing sheets.
In a continuous-web printing machine it is of importance that the cylinders of
the several pairs should be driven at exactly uniform and unvarying speed and
that the driving mechanism should be of such a nature as to provide for the
adjustment of each pair of cylinders in a lateral direction relatively to the other
pair or pairs.
The said Invention consists in the combination with two or more pairs of type
and impression cylinders, adjustable laterally towards and from each other of spur
wheels on the shafts of the cylinders, and endless spur-toothed racks engaging with
but supported independently of the said spur-wheels, and serving by their movement
to impart motion to the said spur wheels and cylinders.
It also partly consists in the combination with two or more pairs of type and
impression cylinders, adjustable laterally towards and from each other, the type
cylinder of each pair being uppermost, of spur wheels on the shafts of the type
cylinders, and endless spur-toothed driving racks engaging with but supported
independently of said spur-wheels, and composed of rigid sections having teeth
upon their outer faces and pivotted together.
It also partly consists in the combination with two or more pairs of type and
impression cylinders, of spur wheels upon the shafts of the cylinders, endless
spur-toothed driving racks gearing with the said wheels, and supporting wheels for
the said racks made separate from and entirely independent of the spur-wheels with
which the racks engage, and arranged outside of and beyond the said cylinders at
the ends of the machine.
It also partly consists in the combination of pairs of type and impression
cylinders, spur wheels on the shafts of the said cylinders, endless spur toothed
driving racks engaging with and driving the said spur-wheels; polygonal supporting-
wheels around which the said racks pass, and pinions engaging with and serving to
operate the said racks.
It also partly consists in the combination with two or more pairs of type and
impression cylinders, of spur-wheels on the shafts of the cylinders, spur-toothed
racks engaging with the said spur-wheels, grippers attached to the said racks, and
supporting wheels around which the said racks pass and which are made separate
from and independent of the said spur wheels and are arranged outside of or
beyond the said cylinders.
It also partly consists in the combination with two or more pairs of type and
impression cylinders, of spur wheels on the abafts of the said cylinders, endless
spur-toothed driving racks engaging with the said wheels, other wheels for carrying
the said racks, and slideways or supports for the racks opposite their points of
engagement with the said spur-wheels; the said slideways serving to hold the
acks uniformly in engagement with the spur-wheels and being preferably grooved,
Hanged, or equivalently constructed to hold and guide the racks laterally as well
S vertically.

page_text: It also partly consists in the combination with pairs of type and impression
cylinders spur-wheels on the shafts of the cylinders, endless spur-toothed racks
gearing with the said spur-wheels, other wheels for carrying the said racks, and
slideways wherein the said racks move, of grippers attached to the inner sides of
the said racks and stationary cams past which the said grippers are carried by the
racks and by which the grippers are opened.
It also partly consists in the combination with a pair of type and impression
cylinders which are fixed laterally, of auxiliary side frames and means for adjusting
them in the said main side frames towards and from the said cylinders, and
pairs of type and impression cylinders journalled in the said auxiliary frames
whereby provision is afforded for accurately adjusting the pairs of cylinders which
are journalled in the said auxiliary side frames, relatively to the pair of cylinders
which are journalled in the said main side frames.
It also partly consists in the combination with a pair of type and impression
cylinders of a main frame wherein they are journalled and inking apparatus for the
said type cylinder, a carriage wherein the inking apparatus is supported and
tracks or ways whereon the said carriage may be moved in a direction lengthwise
of the cylinder.
In a machine wherein three pairs of type and impression cylinders are used, the
inking apparatus for the first and last pairs of cylinders can be movod laterally
to enable the type cylinders of the said first and last pairs to be removed and
other type cylinders substituted for them; but where there is little space between
the pairs of cylinders, the inking apparatus of the middle pair of cylinders cannot
be moved laterally because of lack of room. The combination last above described
provides for removing the inking apparatus of the middle pair of cylinders by a
movement in the direction of the length of the said cylinders.
After the continuous web has received impressions from the two or more pairs
of cylinders it is commonly cut off into sheets as it issues from the machine; the
Invention therefore further partly consists in the combination with two or more
pairs of type and impression cylinders for printing upon a continuous web, of
devices for cutting off sheets from the web after printing, tapes or other carriers
moving at the same speed as the web and serving to take the sheets as they are
cut off, and a cylinder or wheels, provided with delivery grippers, and geared so
that the said grippers will move at a quicker speed than the tapes or other carriers
first mentioned, thus serving to deliver the sheets with an accelerated movement.
The advantages of this accelerated movement are that it makes a break or
separation between the sheets cut off, and enables the delivery grippers carried by
the aforesaid cylinder or wheels to get into position at the proper times to take the
sheets successively.
In the accompanying Drawings
Figure 1 is a longitudinal vertical section of a continuous web printing machine
embodying this Invention.
Figure 2 is a transverse vertical section thereof, and
Figures 3, 4 and are views of details drawn to an enlarged scale; illustrating
a portion of a spur-toothed rack, its grippers and cams for opening the grippers.
Similar letters of reference indicate corresponding parts throughout the
Drawings.
A indicates the main stationary side frames of the machine which frames may
be of any suitable form, and connected by suitably arranged stretchers.
B, C indicate respectively a type cylinder and an impression cylinder which are
journalled in suitable bearings in the side frames. These bearings are fixed,
that is they are not adjustable laterally, although the box of the type or upper
cylinder B may be adjusted upwards and downwards in the usual manner.
On each side of the cylinders B, C are arranged other type and impression
cylinders B, C which are like the cylinders B, C, but instead of being journalled
in the main frames A they are journalled in auxiliary frames A¹, which are

page_text: mounted on slides a, and are capable of adjustment independently of each other
towards and from the centre of the machine, that is towards and from the central
or middle cylinders B. C.
As here shown each auxiliary side frame A¹ bas upon it a nut b and c indicates
a screw mounted in fixed bearings so that it may not move lengthwise, and
engaging with the said nut. Upon the screw, C, is secured a worm wheel c¹ and a
worm or screw c² engages with the worm wheel.
The two worms or screws c² on opposite sides of the machine are mounted on the
same shaft c³, which may be turned by a wrench applied to either end. By
turning the said shaft, both worms or screws will be operated and the auxiliary
frames A' at opposite sides advanced together. By this means I may adjust each
outer pair of cylinders B' C¹ independently of the other pair towards and from the
middle cylinders B, C, and the worm wheels and screws employed for the purpose
serve also to hold the side frames A¹ and the cylinders carried thereby, in place
after their adjustment.
This combination of the middle pair of cylinders which are non-adjustable
laterally, and one or more pairs of cylinders B¹ C on each side thereof, adjustable
towards and from the middle cylinders forms an important feature of this
Invention, but so far as some other features of the Invention are concerned I may
use two or more pairs of cylinders, each pair being adjustable laterally relatively to
the other or I may use two or more pairs of non-adjustable cylinders.
It is often desired in machines of this class to remove the type cylinder and
substitute another, larger or smaller, as may be necessary, the upper parts or caps
of the housings which are formed in the side frames A, A¹, must therefore be
removable. I make the bearings of all the type cylinders of solid blocks d of the
form shown in dotted lines in Figure 1, and I vary the distance between the lower
surfaces of these blocks and the bearings or holes therein to suit cylinders of
different diameters and the blocks always are intended to rest solidly in the bottom
of their housings. For example, with a cylinder of large diameter the bearings or
holes in its blocks d would be at considerable distance from the bottom thereof,
while if the cylinder be of lesser diameter, the bearings or holes will be nearer the
bottom thereof.
The cylinders of each pair are provided with the usual bearers or bearing rolls, e,
which roll together and preserve the surfaces of the cylinders against injury and
are geared together by gear wheels e'.
The bearers or bearing rolls, c, consist of cylindrical portions or surfaces inside
of and close to the gear wheels e¹. They may be formed by circular flanges on the
inner sides of the gear wheels e' of the same diameter as the pitch diameter of said
wheels.
In order to rotate the cylinders upon the shaft of each type cylinder B, B¹, and
near the ends thereof, are secured spur gear wheels D, through which a positive
and uniform motion is transmitted to the said type cylinders, and through the gear
wheels e¹, to the impression cylinders.
At each side of the machine and in the same vertical planes as the spur wheels D,
are endless spur toothed racks D₁ which intermesh with and drive the said gear
wheels D, and through them the cylinders.
Each endless rack is composed of rigid sections jointed or pivotted together at f
and the teeth are so spaced or formed that the space at the joint, between the end
teeth of any two rack-sections is a proper tooth space, and of the same size as the
spaces in each individual section. These endless racks are mounted on wheels E,
which are of polygonal shape or have polygonal seats in which the racks fit, and
both wheels are adapted to rotate freely as the racks are moved over and
around them.
The shafts E' of the wheels E are journalled in the fixed side frames A and are
placed at such distance apart as to preserve the proper tension of the racks. It
might be desirable to make the bearings of one shaft E' slightly adjustable to

page_text: enable the racks to be tightened if their joints or connecting pivots become much
worn, but I have not thought it necessary to show such an adjustment.
The racks D¹ are in gear with all the type cylinders B B' and transmit an
uniform and steady motion to them, and the transmission of such motion is not
interfered with in any way by the adjustment of the cylinders towards and from
each other.
It is evident that the adjustment of the cylinders will not in any way affect
the tension of the endless racks, as would be the case if the wheels E were
mounted on the shafts of the type cylinders at the opposite ends of the machine.
I do not include in my Invention an endless band chain, or belt for operating
the type cylinders, as such devices have before been used, but they are not nearly
so advantageous as the endless rack for many reasons.
.
The chains or bands heretofore used have had lugs or pins on their inner sides
and hence it has been necessary to place one or both of the chain wheels over
which they drive directly on the shaft or shafts of the cylinder or cylinders.
When so arranged and combined every adjustment of the cylinders laterally, no
matter how slight, varies the tension of the chains, which is a great disadvantage.
The endless racks are very strong, they transmit a smooth and uniform motion
to the cylinders, the wheels into which they gear for driving are entirely separate
from and independent of the wheels on which they are supported, the spur wheels D
rest upon their upper and exterior surfaces and the cylinders can be lifted out
without disconnecting the racks from the wheels E which carry them, and they
are altogether more reliable and desirable for the purpose than are chains or bands
such as have been used heretofore.
The racks may be driven by imparting a positive motion to the wheels. E at one
end of the machine, but I prefer to drive them by pinions or spur wheels, gearing
into their faces, and I have so represented the driving mechanism in this example
of my Invention.
F indicates a shaft extending transversely across the machine and provided with
pinions or spur wheels g which engage with the racks D¹, upon the said shaft is
also secured a driving pulley F', for the reception of a driving belt.
It is very essential that the racks D' should be supported opposite the points of
their engagement with the spur wheels D so that they will gear into said wheels
to their pitch line and avoid slip.
Below the upper or driving portion of each rack I arrange a rest slideway or
support G therefor, which is supported upon brackets h projecting from the main
frames A. As here shown these rests or slideways extend from one end to the
other of the machine; past all the spur wheels D and the driving pinions g and
forin adequate supports for the racks and prevent any tendency of the racks to
ride over or move out of gear with the wheels D. The said slideways have flanges
at the sides or recessed bearing surfaces as shown in Figures 1, 3 and 4 and the racks
are thereby held in place laterally as well as vertically. The whole lower or
interior surface of the racks inay slide on the slideways G, or I may provide them
with rollers at the joints.
The racks D¹ not only serve as drivers for the type cylinders but they also serve
as carriers for the continuous web i of paper, which is taken from a roll H as
shown in dotted lines in Figure 1.
Upon the inner sides of the racks are grippers I which grasp the web as they
arrive at the upper or operative part of the racks and are released therefrom as
they reach the opposite end of the machine.
The construction and operation of these grippers will be best understood from
Figures 3, 4 and 5. -
Each gripper I is composed of a fixed or rigid jaw j, and a pivotted movable
jaw, having a depending tail. Coiled upon the pin by which the movable jaw
is pivotted to the fixed or rigid-jaw, is a spring or springs ja which tends or tend to
hold the movable jaw tightly closed on the fixed or rigid jaw."

page_text: At the end of the machine at which the roll H is located are stationary cams k
of the form shewn in Figures 3 and 5. As the grippers are brought by the racks
opposite these cams their tails are acted on by the cams, and their movable
jaws are opened to take in the web and are at once closed by the action of the
At the opposite end of the machine are other stationary cams k¹ and as the
gripper reach these cams their movable jaws are opened and the web released
from them.
5 springs 1.
Any number of grippers may be employed in each rack.
I will now describe briefly the inking apparatus but I do not make any claim to
the arrangement or manner of combining the several rollers and devices my
Invention being limited to the manner of supporting and adjusting or moving the
apparatus as a whole.
Each of the end cylinders B' has an inking apparatus K which is supported in
a carriage K' that is movable towards and from the cylinder upon ways I formed
on the side frames A.
If it is desired to remove either cylinder B¹ from its bearings all that is necessary
is to raise the inking rollers as shewn in dotted outlines at the right hand of
Figure 1 and then move the carriage K¹ away from the cylinder.
The middle type cylinder B is likewise provided with an inking apparatus L
supported in a carriage L', but this carriage instead of being movable transversely
to the cylinder is movable lengthwise thereof, along tracks or ways m, extending
horizontally from the side of the machine as shewn in Figure 2. When it is
desired to remove the cylinder B from its bearings the inking rollers are lifted or
swung upward as shewn in dotted lines in Figure 1, and the carriage L¹ is then
moved horizontally away from the cylinder.
In a machine of this class it is very advantageous to have the inking apparatus
of the middle cylinder movable lengthwise of the cylinder as there is not room
between the cylinders to admit of its being moved transversely to the length of
the cylinder or length wise of the machine. If more than three pairs of cylinders
are employed the carriages carrying the inking apparatus of all cylinders except
the end ones is made capable of movement in the same direction as the carriage L¹
here shown.
I will now describe how motion is transmitted to the inking apparatus but I do
not make any claim thereto.
Upon the side of the machine is arranged a horizontal shaft M which is rotated
by bevel gear wheels from the driving shaft F and connected with each inking
apparatus K is a vertical shaft N which is connected with and rotated from the
haft M by pairs of bevel gears n. The shafts N are fitted to bearings on the
arriages K and are movable with the said carriages towards and from the middle
ylinder B.
Supported on the carriage L¹ of the middle cylinder B is a vertical shaft O
which receives motion from the shaft M by bevel gear wheels o o' and in order to
nable the carriage L' to be moved as described, the wheel O on the shaft M should
e fitted thereto with a feather so that it may be moved out of engagement with
ts fellow wheel when the carriage is to be shifted.
Although I have only shewn the racks D¹ as engaging with spur wheels D upon
he type cylinders B B₁ such wheels might be placed on the shafts of the impression
ylinders C C; the said impression cylinders would then transunit motion through
he wheels e¹ to the type cylinders.
After the continuous web has received impressions from the several pairs of
linders it is commonly cut off into sheets as it issues from the machine and I
ill now describe briefly the apparatus for thus cutting off and delivering the
eets premising however that various other forms of delivery apparatus may
used.
At the delivery end of the machine are rolls o³ ³ between which the continuous
eb of paper passes and which receive motion from a shaft o. Just in advance of

page_text: the rolls o 3 is a bed or support P over which the web passes and to which is fixed
a shear blade o, o indicates a movable shear- blade carried by a cylinder or drum P¹
At each revolution of the cylinder
which receives rotary motion from the shaft o*.
or drum P¹ a sheet is severed from the web.
In advance of the shear blades of 0 are upper and lower series of tapes P2 P3 5
which are mounted on wheels o' and which are operated by a shaft P' and suitable

at the same speed as the continuous web and carry forward the sheets between
them.
Q indicates a rotary cylinder or series of wheels provided with delivery grippers p 1
two sets of grippers at opposite points in the cylinder or wheels being here shewn.
This cylinder is geared to move at such a speed that its surface velocity will be
greater than the speed of movement of the continuous web and the tapes P* Ps
and hence when the sheets are taken by the grippers 2 from the tapes P P³ they
will be delivered with an accelerated movement.
This accelerated movement of the cylinder Q and the grippers p is advantageous
as it produces a break between the sheets cut off and enables the grippers p to
get into position at the proper times to take the sheets successively.
Inasmuch as the cylinder Q here shewn has two sets of delivery grippers p it
should make a half revolution at each delivery. The grippers p may be acted upon
by a stationary cam Qover which they are carried in order to open them at the
proper time to deliver the sheets into the box R and may be held open by said
cam until they come to a position to close on the sheet presented to them by the
tapes P' p³
Any mechanism may be employed for rotating the cylinder Q which will move
the grippers p at a quicker speed than the tapes P2 P³.
In some cases it may be desirable to slit or divide the sheets lengthwise after
they are. cut off by the shear blades 05 0 and I have here shewn rotary discs
or cutters o³ which may be employed for such purpose although I make no claim
to them.
Having now particularly described and ascertained the nature of my said
Invention and the manner of performing the same I declare that what I
claim is :-
First. The combination with two or more pairs of type and impression cylinders,
adjustable laterally towards and from of each other, of spur wheels on the shafts
of the said cylinders and endless spur toothed racks, engaging with but supported
independently of the said wheels, for imparting motion to the said cylinders,
substantially as described.
Second. The combination with two or more pairs of type and impression
cylinders adjustable laterally towards and from each, other of spur wheels D on
