Year: 1870

page_text: LETTERS PATENT to John Gough, of Kirby Street, Hatton Garden, in
the City of London, Engineer and Machinist, for the Invention of
"IMPROVEMENTS IN PRESSES FOR RELIEF STAMPING OR PRINTING AND IN
RESERVOIR INK OR COLOUR ROLLERS FOR REGULATING THE FLOW OF INK OR
COLOUR THEREFROM.
"
Sealed the 22nd December 1870, and dated the 28th October 1870.
PROVISIONAL SPECIFICATION left by the said John Gough at the
Office of the Commissioners of Patents, with his Petition, on the
28th October 1870.
I, JOHN GOUGH, of Kirby Street, Hatton Garden, in the City of
London, Engineer and Machinist, do hereby declare the nature of the
said Invention for "IMPROVEMENTS IN PRESSES FOR RELIEF STAMPING OR
PRINTING AND IN RESERVOIR INK OR COLOUR ROLLERS FOR REGULATING THE FLOW
OF INK OR COLOUR THEREFROM," to be as follows:-―
In the process of relief stamping or printing such as applied to paper
headings and envelope flaps and fronts it is necessary to clean the surface
of the die or stamp after each supply of ink or colour thereto and before

page_text: the paper is laid upon it, and this process has always been a tedious one
when done by hand as the cleaning necessitated a stoppage of the press.
Now according to my Invention I construct my press so that the cleaning
of the die or stamp is done automatically and without any stoppage by
an apparatus connected with the press; and this I accomplish by making
the die plate slide in a suitable guide or bearing frame or support by
means of cords, chains, pinions, ratchet, or other gearing attached to or
leading from the press head or plunger rod or screw. The die plate
is brought under or against a wiper after receiving the supply of ink
or colour from a roller or pad, and the wiper made to shift itself
automatically to bring a fresh portion of it into work for each movement
of the die. One way this may be effected is by fitting a disc, cross head,
or quadrant on the press head or plunger rod or screw which receives
rotary motion when the rod or ball lever is turned to lift the plunger
and "force" up clear of the paper, this disc or its equivalent has a rod or
chain fastened to it which is led over or round pulleys to the sliding die
plate. In the back or side motion the die plate passes under the wiper
and receives its supply of ink or colour from the roller at the end of its
stroke, the wiper is then caused to descend and as the die returns it
comes in contact with the wiper, and the top surface is cleaned, leaving
sufficient ink or colour in the engraved or sunk device of the die for
stamping or impressing the paper. The wiper.is preferably composed of a
length of paper on a roller, and the edge or some other part of the die plate
has a pin which is caused to come in contact with a lever for actuating a
ratchet wheel on the roller, so that the roller is moved round a sufficient
distance to bring a fresh portion of the wiping paper into work. The
paper is received on this roller from another roller and a friction roller or
spring retards its rotation so that sufficient tension is put upon the paper
to prevent slackness. The paper passes under a flat pad to form a
surface for wiping the die clean. The disc is slotted and a pin or stud
moves in this slot without imparting motion to it while the plunger is
giving the required impression and until the plunger is again clear of the
impressed paper.

page_text: thereof, the other end forming a bearing for the supporting pin on which
it is held by a spring:
The employment of the screw cap in the end of the inking or colour roller
forms the second part of my Invention as by it I am enabled to dispense
with the composition roller for sucking the ink or colour through the
meshes as described in my former Patent. The roller with the cap as
just described is applicable to other presses and may be used directly on
to the type of ordinary printing machines. The ink reservoir may be of
a segmental form if preferred and receive an intermittent motion from
the die.
In the press before described stops and springs are employed for
registering and for casing the motion..

filed by the said John Gough in the Great Seal Patent Office on
the 28th April 1871..

WHEREAS Her most Excellent Majesty Queen Victoria, by Her'
Letters Patent, bearing date the Twenty-eighth day of October, in the
year of our Lord One thousand eight hundred and seventy, in the thirty--
fourth year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto me, the said John Gough, Her special licence that I,
the said John Gough, my executors; administrators, and assigns, or
such others as I, the said John Gough, my executors, administrators,
and assigns, should at any time agree with, and no others, from time
to time and at all times thereafter during the term therein expressed.
should and lawfully might make, use, exercise, and vend, within the
United Kingdom of Great Britain and Ireland, the Channel Islands,
and Isle of Man, an Invention for "IMPROVEMENTS IN PRESSES FOR RELIEF
STAMPING OR PRINTING, AND IN RESERVOIR INK OR COLOR ROLLERS FOR REGULATING
THE FLOW OF INK OR COLOR THEREFROM," upon the condition (amongst
others) that I, the said John Gough, my executors or administrators,

page_text: by an instrument in writing under my, or their, or one of their hands
and seals, should particularly describe and ascertain the nature of the
said Invention, and in what manner the same was to be performed, and
cause the same to be filed in the Great Seal Patent Office within six
calendar months next and immediately after the date of the said Letters
Patent.
NOW KNOW YE, that I, the said John Gough, do hereby declare
the nature of my said Invention, and in what manner the same is to
be performed, to be particularly described and ascertained in and by
the following statement thereof, reference being had to the Drawings
hereunto annexed, that is to say :-
In the process of relief stamping or printing such as applied to paper
headings and envelope flaps and fronts, it is necessary to clean the
surface of the die or stamp after each supply of ink or colour thereto and
before the paper is laid upon it, and this process has always been a
tedious one when done by hand as the cleaning necessitated a stoppage of
the press.
Now according to my Invention I construct my press so that
the cleaning of the die or stamp is done automatically and without any
stoppage by an apparatus connected with the press, and this I accom-
plish by making the die plate slide in a suitable guide bearing frame or
support by means of cords, chains, pinions, ratchet or other gearing,
attached to or leading from the press head or plunger rod or screw.
The die plate being brought under or against a wiper after receiving
the supply of ink or color from a roller or pad, and the wiper made to
shift itself automatically to bring a fresh portion of it into work for
each movement of the die. One way this may be effected is by fitting
a disc, crosshead, or quadrant on the press head or plunger rod or screw,
which receives rotary motion when the rod or ball lever is turned to
lift the plunger and "force" up clear of the paper. This disc or its
equivalent has a cord or chain fastened to it which is led over or round
pulleys to the sliding die plate. In the back or side motion the die
plate passes under the wiper and receives its supply of ink or color
from the roller at the end of its stroke; the wiper is then caused to
descend and as the die returns it comes in contact with the wiper and
the top surface is cleaned, leaving sufficient ink or color in the engraved
or sunk device of the die for stamping or impressing the paper. The
wiper is preferably composed of a length of paper on a roller and the

page_text: edge or some other part of the die plate has a pin which is caused to
come in contact with a lever for actuating a ratchet wheel on the
roller, so that the roller is moved round a sufficient distance to bring a
fresh portion of the wiping paper into work. The paper is received on
this roller from another roller, and a friction roller or spring retards its
rotation so that sufficient tension is put upon the paper to prevent
slackness. The paper passes under a flat pad to form a surface for
wiping the die clean. The disc is slotted and a pin or stud moves in
this slot without imparting motion to it while the plunger is giving
the required impression and until the plunger is again clear of the im-
pressed paper.
I prefer an ink or color roller of the construction patented by me on
the 4th day of March, 1869, No. 666, and I regulate the flow or supply
of ink or color through the meshes of the wirework or other perforated
covering by means of a screw cap placed on or in one end thereof, the
other end forming a bearing for the supporting pin on which it is held
by a spring.
The employment of the screw cap in the end of the inking or color
roller forms the second part of my Invention, as by it I am enabled to
dispense with the composition roller for sucking the ink or color
through the meshes as described in my former Patent. The roller with
the cap as just described is applicable to other presses, and may be used
directly on to the type of ordinary printing machines. The ink reservoir
may be of a segmental form if preferred, and receive an intermittent
motion from the die.
In the press before described stops and springs are employed for
registering and for easing the motion.
The manner of carrying my Invention into effect is represented in the
accompanying Drawings, in which Figure 1 is a front view of a press
fitted with a cord for drawing the sliding plate to and fro as the ball or
hand lever is turned.
65
The press is composed of a bed plate A with an arm, or standard B of
curved form to carry the screw C, on the lower part of which the
force" D is secured; the screw passes through a threaded portion of.
the head E, so that when the balls are turned or swung round the screw,
and force is lifted or depressed in the manner well known. One arm

page_text: 66
.
of the ball levers has a pin or stud F depending from it, and this takes
into a hole in a disc or circular plate G to impart a motion to it when
the balls are swung. The hole is slotted or of an elongated character
to permit of an additional rotation of the screw C to compel the force D
to act upon the work and make the necessary impression. The disc has
a pin or stud H for supporting a spring I, which is fitted over it and
the stud F, so that when the force has to be lifted by the return up
twist of the screw, the spring which has been extended returns to its
normal condition and takes the stud F with it, and consequently the
ball levers, and as soon as the stud F has reached the end of the slot it
begins to take the disc round with it and then the cord J which passes
round it draws the die plate to the opposite end of the bed A in its
"race." This movement causes the die to pass under a pad K, over
or against which a wiper or band is stretched in its transit and then
continue its course under the inking roller or "dab" L to receive a
supply of ink for the next printing. The die passes completely under
the inking
dab" and remains there until the action of the ball levers
is reversed for the next impression, and when this happens the die again
comes against the inking "dab" and receives a further supply of ink, so
that if the first inking has not sufficiently covered the surface or filled
the imprint or hollows of the die, it is effectually done at the second
inking. During this return movement the die come in contact with
the wiper K, and the ink upon the surface is thereby wiped off by it
leaving the imprint or hollows still full of ink, and in this state it passes
to the opposite end of its course and immediately under the force for
the next downstroke by the screw C. It will here be seen that the
band is left in a dirty state, and to ensure a clean portion of the band
being brought under the pad after each impression I arrange a lever M
on the axle or pin of one of the band rollers or bobbins, and this is
struck by a projecting pin N, Figure 2, on the edge of the sliding plate
to rotate it a certain distance and to cause the bobbin to wind a
portion of the band upon it, the distance of the rotation of the bobbin
being governed by the number of teeth of the ratchet wheel O fixed
thereto, the lever, paul, or catch P slides over at each stroke. The
band which may be of paper or of canvas or other material is wound
from a bobbin Q and a tension is put upon it by springs so that the
portion bearing against the pad K is always flat. I arrange a weight
upon the lever M to return it to its normal condition at each return

page_text: stroke of the sliding plate and after the pin N leaves it. In practice it
is only necessary to propel the ball lever in one direction, and that is to
push the screw downwards to obtain the impression as the weighted
lever R which is hung upon the fulcrum pin S causes it to rebound
and lift the force from the paper or other material being printed or
impressed and also to carry the sliding plate Y along under the inking
roller or
"dab" L. At each end of the bed A I fix a guide pulley T to
lead the cord from the sliding plate to the disc G, it passing round other
pulleys U on its way thereto as shown. This will be clearly understood
by the side view Figure 3. I do not in all cases employ a weighted
lever to return the sliding plate as an additional groove can be arranged
in the edge of the disc G for a cord B to pass over a pulley W at the
back of the press when the descent of the weight X will effect the
movement, as seen in Figure 4.
There are various mechanical modes of ensuring the movements of
the sliding plate beside the one mentioned, as, for instance, a lever
centred near the press head with its lower end attached to the plate and
its upper end acted upon by an excentric can be employed, or a train
of toothed wheels could be used as shown in Figures 4, 5, and 6; here
a plain portion of the screw C carries a collar a supporting a toothed
wheel gearing into a pinion c, and this takes into another wheel d
feathered upon a vertical spindle e which is held in position by the
brackets ff, so that a wheel g on its lower end can gear into a rack h
on the edge of the sliding plate.
The perfect action of this arrangement is maintained by the rise and
fall of the upper set of wheels with the collar a which moves up or
down as the screw C turns up or down. The wheel 6 has only a suffi-
cient number of teeth upon it to cause a complete revolution of the
pinion c, and this corresponds with the length of travel of the sliding
plate Y, and as the last tooth acts upon the pinion and passes the line
of centres it escapes out of gear and leaves the same and consequently
the sliding plate stops. This sliding plate can be held at the end of its
travel by a spring pin to ensure perfect registration of the die with
the force, but other means may be adopted for the purpose if desirable.
I have not in these Figures shown the inking or the wiping apparatus
on the bed plate, but they would be fitted in the same or in some
equivalent manner as in the first arrangement.

page_text: Figures 7 and 8 represent the second part of my Invention. i is a
barrel or tube forming the ink or color reservoir; it is perforated with
holes or formed of wirework to permit of the ink or color flowing
through to the blanket or porous body ; on the outside to saturate it.
k is a screw cap by the screwing up of which the flow can be regulated
to the greatest nicety. The barrel has a socket to take over the pin
m of the standard n, and it is kept thereon by a spring p lodging in
the groove of the rim; this spring can be lifted out of the groove when
the roller has to be refilled or for other purposes. The roller need not
be of circular form in cross section as the die in acting against it does
not cause it to rotate sufficiently to bring all parts into operation, so it
can be made of the form shown in Figure 8; and this can be filled
through an opening at the top which is kept closed by a screw cap k.
I have in the foregoing only referred to the roller shown in Figure 7
as being used for the press above described, but by a slight modification
it can be made available for all kinds of printing purposes, whether by
hand or by power, by fitting the cap and its opposite end with pins to
ride in the forks, such as those on the sides of an ordinary printing
machine, as by this construction of rollers the ordinary composition
distributing rollers can be dispensed with or in any case some of them
can be dispensed with.
And having now described the nature of my said Invention and in
what manner the same is to be performed, I declare that I claim as my
Invention,-
Firstly. The general construction and arrangement of apparatus to be
applied to relief stamping and printing presses, as hercin-before described
and shewn, whereby the inking and wiping of the die are effected by
the movement of the press screw.
Secondly. The arrangement of apparatus for ensuring a fresh portion
of the band or wiper being brought into action, substantially as described
and shown.
Thirdly. The construction and employment of reservoir rollers in the
manner herein-before described and shown in reference to Figure 7.
Fourthly. The construction of the modified form of reservoir roller
as hercin-before described, for use in printing presses and machines
generally.

page_text: And, fifthly, I claim the construction and employment of reservoir
ink or color rollers of the form shown in Figure 8.
In witness whereof, I, the said John Gough, have hereunto set
my hand and seal, this Twenty-eighth day of April, One thousand
eight hundred and seventy-one.
