IMPROVEMENTS IN PRINTING MACHINES to be as follows:- و
Year: 1884

page_text: I, HENRY HARRIS LAKE, of the firm of Haseltine, Lake, and Co, Patent Agents,
Southampton Buildings, London, in the County of Middlesex do hereby declare the
nature of said Invention for "IMPROVEMENTS IN PRINTING MACHINES to be as
follows:-
و"
This Invention relates to printing machines in which two or more pairs of type
and impression cylinders are arranged at such distances apart that the impression
of each type cylinder will register with the impression or impressions of the other
type cylinder or cylinders, and in which the several cylinders are rotated in unison
by means of endless spur-toothed racks gearing with spur-wheels upon the shafts
of the several type cylinders or impression cylinders, the said endless spur-toothed
racks being supported upon or carried by wheels independent of and beyond or
outside of the type and impression cylinders.
The said Invention consists partly in the combination with a feed board and two
or more pairs of type and impression cylinders and spur-wheels on the shafts of the
said cylinders, of two endless spur-toothed racks, engaging with and driving the
said spur-wheels, and gripper rods or bars extending between and connected with
the said racks and provided with receiving grippers for taking the sheets, bags or
articles from the feed board and presenting them to the type cylinders of the
several pairs in succession.
It also partly consists in the combination with two or more pairs of type and
impression cylinders geared together, one cylinder of each pair being provided with
a spur-wheel and the other with a circumferential groove opposite the spur-wheel,
of two endless spur-toothed racks, working in the grooves in the several grooved
cylinders and gearing into the spur-wheels on the other cylinders and supporting
wheels for the said racks arranged outside of or beyond the said cylinders. The
aforesaid grooves afford provision for the passage of the racks between the
cylinders of each pair.
It also partly consists in the combination of two or more pairs of type and
impression cylinders provided with peripherical recesses extending lengthwise of
them and also provided with spur-wheels, of two endless spur-toothed racks gearing

page_text: into the said spur-wheels for driving the cylinders, supporting wheels for the racks
outside of or beyond the said cylinders, and gripper-rods, provided with grippers
extending between and connected with the said racks, and adapted to be received
in the said recesses of the cylinders in passing between the cylinders of the several
pairs.
It also partly consists in the combination with two or more pairs of type and
impression cylinders, provided with spur wheels, of endless spur-toothed racks
gearing with the said spur-wheels for driving the cylinders, gripper rods or bars
provided with receiving grippers, extending between and connected with the said
racks, and a reciprocating carrier or carriers provided with delivery grippers
arranged at the delivery end of the machine and adapted to take the printed sheet
from the receiving grippers and by a movement outward to deliver the sheet.
According to the said Invention the type and impression cylinders are mounted
in bearings in the side frames and the bearings of the upper or type cylinders may
be adjustable in a well known manner, by means of screws to bring the cylinders
of each pair into proper relation with each other.
Each of the type cylinders should be provided with inking apparatus.
The cylinders of each pair are geared together by wheels, to cause them to
rotate in unison.
Endless driving racks are provided which have spur teeth and are composed of
rigid sections, pivotted or connected by pins or pivots, the space at each joint being
equal to a tooth space.
These racks are mounted on polygonal wheels arranged on shafts outside of or
beyond the pairs of cylinders. The left hand wheel may be mounted in fixed
bearings but the right-hand wheel is mounted in bearings which may each be
adjusted by means of a screw fitting a nut on the bearing. Each screw has a
worin-wheel, fixed to it. With the worm-wheel engage worms or screws on a
shaft which extends transversely of the machine and may be turned at either end.
By this means I provide for regulating the tension on the racks.
Upon each of the type-cylinders is a spur-wheel and opposite the spur wheels
the impression cylinders are provided with grooves or portions of reduced diameter.
The racks work in the grooves or portions of reduced diameter, and engage with
the spur wheels. As the cylinders of each pair are geared together by the wheels,
the cylinders are all caused to move in unison.
A driving shaft extends transversely across the machine and is provided with
fast and loose pulleys to receive a driving belt; and with pinions, which gear into
and drive the racks, and through them the cylinders; but if desired the driving
shaft might be dispensed with and the motive power applied directly to one
cylinder and through the racks to the other cylinders.
In order to support the upper portions of the racks which are always operative
I provide slideways or guides which between the cylinders are supported by
brackets from the side frames. These slideways may be channelled or provided
with side flanges so as to guide the racks laterally, and the racks may have their
whole under or inner surfaces fitted to the slideways or guides, or may be provided
at the pivots with rollers adapted to run in the said slideways or guides.
A feed board is arranged above the racks and from it the sheets or articles to be
printed may be fed.
Extending between and connected to the racks are pairs of bars or rods, upon
which at intervals along their length are fixed grippers and cushions or pads on
which the grippers may close. These grippers constitute the receiving grippers
of the press and take the sheets or articles to be printed from the feed board.
At the end of each gripper bar or rod is an arm to which is attached a spring;
this spring tends to hold the grippers tightly closed on the cushions or pads, and
causes them to tightly hold the sheets or articles.
Adjacent to the edge of the feed board is a cam or projection; as the gripper
rods or bars pass this cam or projection their arms bear upon it and the rods or
bars are turned so as to open the grippers. When released the grippers close on

page_text: the edge of the sheet or article presented to them, draw it from the feed board, and
carry it successively between the cylinders of the several pairs.
The cylinders of the several pairs are provided with peripherical recesses which
receive the grippers and enable them to pass between the cylinders.
Near the delivery end of the press is a cam or projection; as the grippers reach
this, the arms strike it and the gripper rods or bars, are turned so as to release the
printed sheets or articles and allow them to be taken by the delivery grippers.
The delivery grippers are attached to a gripper carriage composed of two end
portions adapted to travel on slideways or guides, and connected by gripper rods
or bars, which are provided with grippers or gripper fingers. The two end portions
of the carriage, are attached to chains, which pass around chain wheels and also
around outer chain wheels at the extreme end of the machine. By rotating the
chain wheels, alternately in opposite directions, the chains, are reciprocated and the
carriage is moved to and fro to enable the grippers, to take the printed sheets or
articles and deliver them into a recepticle.
Upon the same shaft as the chain wheels is a pinion and below is a shaft,
bearing at one end a wheel, which engages with a pinion, and at the other end
and outside the frames of the machine is a second pinion. A rack-bar rests upon
and gears with the said pinion. The said rack-bar is forked to embarce and slide
upon the shaft of the end impression cylinder. Upon the rack is a pin or roller,
which engages with a grooved cam, on the shaft of said impression cylinder and by
the said can the rack is reciprocated and the reciprocating motion is transmitted
to the chains, and to the gripper carriage.
The gripper rods or bars of the upper carriage are provided at their end with
arms which are connected by toggle levers, and a spring. When the toggle levers
are straightened or brought into line the grippers, are open, or held apart and this
is the position they occupy during their inward movement.
As the grippers reach the end of their inward movement the toggle levers, striko
a stop and are thereby deflected or "broken down."
The said spring then acts and draws or moves the grippers, together or closes
them on the printed sheet, or article, whereupon they move outward. As they
reach the end of their outward movement the toggle levers strike a projection or
stop and are straightened, thereby opening the grippers, and causing them to drop
the sheet or article.
Immediately below the driving shaft is a second shaft upon which are wheels
which support the racks opposite the points where the pinions gear into them, and
prevent the racks from being deflected.
If desired I may provide the type cylinders with circumferential grooves instead
of the impression cylinders, and in such case the wheels with which the racks
engage would be fixed on the shafts of the impression cylinders.

page_text: I HENRY HARRIS LAKE, of the firm of Haseltine, Lake, and 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 and by the following statement:―
This Invention relates to printing machines in which two or more pairs of type
and impression cylinders are arranged at such distances apart that the impression
of each type cylinder will register with the impression or impressions of the other
type cylinder or cylinders, and in which the several cylinders are rotated in
unison by means of endless spur-toothed racks gearing with spur-wheels upon the
shafts of the several type cylinders or impression cylinders, the said endless spur-
toothed racks being supported upon or carried by wheels independent of and
beyond or outside of the type and impression cylinders.
The said Invention consists partly in the combination with a feed board and
two or more pairs of type and impression cylinders and spur wheels on the shafts
of the said cylinders, of two endless spur-toothed racks, engaging with and driving
the said spur-wheels, and gripper rods or bars extending between and connected
with the said racks and provided with receiving grippers for taking the sheets,
bags or articles from the feed board and presenting them to the type cylinders of
the several pairs in succession.
It also partly consists in the combination with two or more pairs of type and
impression cylinders geared together, one cylinder of each pair being provided
with a spur-wheel and the other with a circumferential groove opposite the spur-
wheel of two endless spur-toothed racks, working in the grooves in the several
grooved cylinders and gearing into the spur-wheels on the other cylinders, and
supporting wheels for the said racks arranged outside of or beyond the said
cylinders; the aforesaid grooves affording provision for the passage of the racks
between the cylinders of each pair.
It also partly consists in the combination of two or more pairs of type and
impression cylinders provided with peripherical recesses extending lengthwise of
them and also provided with spur-wheels, of two endless spur-toothed racks gearing
into the said spur-wheels for driving the cylinders, supporting wheels for the racks
outside of or beyond the said cylinders and gripper rods provided with grippers
extending between and connected with the said racks, and adapted to be received
in the said recesses of the cylinders in passing between the cylinders of the
several pairs.
It also partly consists in the combination with two or more pairs of type and
impression cylinders, provided with spur-wheels, of endless spur-toothed racks
gearing with the said spur-wheels for driving the cylinders, gripper rods or bars
provided with receiving grippers extending between and connected with the said
racks, and a reciprocating carrier or carriers provided with delivery grippers
arranged at the delivery end of the machine and adapted to take the printed
sheet from the receiving grippers and by a movement outward, to deliver the
sheet.
In the accompanying Drawings.
Figure 1 is a longitudinal vertical section of a printing machine, constructed
according to this Invention.
Figure 2 is a similar section of the feeding end of the machine.
Figure 3 is a plan of a part of the mechanism shown in Figure 2.
Figure 4 is a section of the delivery end of the machine and
Figure 5 is a plan of the mechanism shown in Figure 4.
Similar letters of reference indicate corresponding parts in the several Figures.

page_text: A, B indicate the type and impression cylinders, three pairs of which are here
shown, but my Invention may be embodied in a machine having two pairs of
cylinders or more than three pairs.
The cylinders A, B, are mounted in bearings in the side frames C, and the
bearings of the upper or type cylinders A may be adjustable in a well known
manner, by means of screws, to bring the cylinders of each pair into proper
relation to the other pairs.
Each of the cylinders A should be provided with inking apparatus, D, like the
right hand cylinder in Figure 1.
The cylinders of each pair are geared together by wheels a, to cause them to
rotate in unison.
E E indicate endless driving racks which are provided with spur teeth and are
composed of rigid sections, pivotted or connected by pins or pivots b, the space at
each joint being equal to a tooth space.
These racks are mounted on polygonal wheels E', arranged on shafts E², outside
of or beyond the pairs of cylinders. The left hand wheel E¹ is here shown as
mounted in fixed bearings, but the right hand wheel is mounted in bearings E³,
which may each be adjusted by means of a screw c fitting a nut on the bearing.
Each screw has a worm-wheel c' fixed to it, and with the worm wheels c¹ engage
worms or screws c³, on a shaft which extends transversely of the machine and may
be turned at either end. By this means I provide for regulating the tension on
the racks E.

the grooves or portions d of reduced diameter and engage with the wheels F. As
the cylinders of each pair are geared together by the wheels a, the cylinders are all
caused to move in unison.
G indicates a driving shaft extending transversely across the machine and
provided with fast and loose pulleys G1, G2, to receive a driving belt, and with
pinions e, which gear into and drive the racks E, and through them the cylinders;
If desired the shaft G might be dispensed with and the motive power applied
directly to one cylinder and through the racks to the other cylinders.
In order to support the upper portions of the racks which are always operative,
I provide slideways or guides H which between the cylinders are supported by
brackets from the side frames C. These slideways may be channelled or provided
with side flanges so as to guide the racks laterally, and the racks may have their
whole under or inner surfaces fitted to the slideways or guides, or may be
provided at the pivots with rollers adapted to run in the said slideways or guides.
I indicates a feed board arranged above the racks Ę and from it the sheets or
articles to be printed may be fed.
Extending between and connected to the racks E are pairs of bars or rods g h.
Upon the bars or rods g, and at intervals along their length, are fixed grippers gl
and at corresponding intervals on the bars or rods h, are cushions or pads h¹, on
which the grippers may close. These grippers constitute the receiving grippers
of the press and take the sheets or articles to be printed from the feed board I
At the end of each gripper-bar or rod g is an arm g' to which is attached a
spring g³, as shown in Figure 3. This spring tends to hold the grippers tightly
closed on the cushions or pads h¹, and causes them to tightly hold the sheets or
articles.
Adjacent to the edge of the feed board I is a cam or projection i. As the gripper
rods or bars g pass this cam or projection, their arms g³ bear upon it, whereby the
rods or bars are turned so as to open the grippers g' as shown in Figures 2 and 3.
When released the grippers close on the edge of the sheet or article presented to
them, draw it from the feed board, and carry it successively between the cylinders
of the several pairs.

page_text: It will be observed that the cylinders of the several pairs are provided with
peripherical recesses ; which receive the grippers and enable them to pass between
the cylinders.
Near the delivery end of the press is a cam or projection . As the grippers g'
reach this the arms g strike it, whereby the gripper rods or bars g are turned so
as to release the printed sheets or articles and allow them to be taken by the
delivery grippers.
Jindicates a gripper carriage composed of two end portions adapted to travel on
slideways or guides k, and connected by gripper rods or bars l, which are provided
with grippers or gripper fingers . The two end portions of the carriage, J are
attached to chains m, one of which is shown, and which pass around chain
wheels m' and also around outer chain wheels m² at the extreme end of the
machine.
By rotating the chain wheels m¹ alternately in opposite directions, the chains m
are reciprocated, and the carriage J is moved to and fro to enable the grippers ¹ to
take the printed sheets or articles and deliver them into a receptacle J*.
Upon the same shaft as the chain wheels m' is a pinion n and below is a
shaft n¹, bearing at one end a wheel n which engages with the pinion; and at
the other end and outside the frame of the machine is a second pinion n³.
K indicates a rack-bar which rests upon and gears with the pinion n³ and which
is forked to embrace and slide upon the shaft of the end impression cylinder B.
Upon the rack is a pin or roller n', which engages with a grooved cam L on the
shaft of said impression cylinder B (see Figure 5) and by the said cam the rack is
reciprocated and the reciprocating motion is transmitted to the chains, m and to
the gripper carriage J.
In Figure 5 I have only shown one side of the machine but the mechanism just
described for operating the gripper carriage is duplicated on the other side of the
machine.
The gripper rods or bars 7 of the carriage J, are provided at their ends with
arms 12, which are connected by toggle levers o and a spring o¹. When the toggle
levers o are straightened or brought into line the grippers are open or held apart,
as shown in Figure 1, and this is the position they occupy during their inward
movement.
As the grippers reach the end of their inward movement the toggle levers o
strike a stop o shown in Figure 5, and are thereby deflected or "broken down" as
shown in Figures 4 and 5.
The spring o¹ then acts and draws or moves the grippers ¹ together, or closes
them on the printed sheet or article, whereupon they move outward. As they
reach the end of their outward movement the toggle levers o strike a projection or
stop o shown in Figures 1. 4 and 5 and are straightened, thereby opening the
grippers, and causing them to drop the sheet or article.
Immediately below the driving shaft G is a second shaft O, upon which are
wheels O which support the racks E, opposite the points where the pinions e gear
into them and prevent the racks from being deflected.
If desired I may provide the type cylinders A with circumferential grooves d
instead of the impression cylinders, and in such case the wheels, F with which the
racks E engage, would be fixed on the shafts of the impression cylinders B.
Having now particularly described and ascertained the nature of my said
Invention, and in what manner the same is to be performed, I declare that what
I claim is:
First. The combination with two or more pairs of type and impression cylinders
and spur-wheels on the shafts of the said cylinders, of two endless spur-toothed
racks engaging with and driving the said spur-wheels, gripper rods or bars
extending between and connected with the said racks and provided with receiving
grippers, and a feed board from which sheets may be taken by the said receiving
grippers, substantially as herein described.

page_text: Second. The combination with two or more type and impression cylinders geared
together and provided with spur-wheels and with circumferential grooves opposite
the said wheels, as herein described, of two endless spur-toothed racks working in
