page_text: larly to those described in reference to Sheet 2 of the Drawings attached
to the Specification thereof, and the objects are,—
Firstly. To arrange mechanism to relief stamping and printing
presses, whereby they can be operated by steam or other equivalent
power in lieu of by hand labour as at present employed.
Secondly. To provide the dies of such printing presses with an
automatic or a mechanical feed of ink or colour, the feed being regu-
lated continuously or intermittently by or through the main screw or
other working part of the press.
Thirdly. To produce a rotation of the ink or colour feeding or distri- 1
buting appliances in a direction reverse to that of the travel of the dies
in relief printing presses.
Fourthly. To combine with a rotating ink or colour distributor a
reservoir whose aperture is capable of being opened and closed at
pleasure.
Fifthly. To employ one or more rotating rollers or wheel brushes to
receive ink or colour upon the exterior, and to deposit it direct upon the
travelling die of relief printing presses.
My Invention will be understood by the following:-On the head of
the main screw I fit a deep or broad toothed pinion, which is geared into 2
by a quadrant shaped wheel whose spindle or shaft is stepped into an
arm projecting from the main standard. This quadrant wheel is in a
piece with a bevel pinion, and it gears into another pinion on a separate
shaft, to which a reciprocating motion is imparted by one or more levers
or rods in connection with a crank arm or its equivalent upon the shaft 2
carrying the band or gut wheel by which the power is communicated
from the prime mover.
According to another method I attach an eccentric or other shaped
disc or plate to the screw head, which disc or plate may be grooved for
a draw chain or a tempered steel band or strip to work in, so that by 3
causing the disc or plate to move the required distance by levers or rods
direct the necessary downward travel of the screw can be effected for
obtaining the impression, a spring or its equivalent working in the
reverso direction will lift the plunger or "force" again after each
printing.

page_text: For feeding or supplying the die with ink or colour I employ a
rotating feeder or distributor, which is constantly in contact with a
reservoir, the outlet from which I prefer to regulate by a pin or rod with
a flattened surface.
The feeder or distributor is rotated in the reverso direction to the
travel of the die by gearing, frictional or otherwise, the rotation being
effected from the mechanism or from the sliding plate referred to in my
former Patent, and independently of the die itself. This is an important
feature in my present Invention, as hitherto from the nature of the ink
or colour imperfect impressions were obtained after a short time, which
are entirely obviated by my method described above.
The ink or colour reservoir may be wholly or partly cylindrical or
other shape, and the aperture can be closed and opened automatically or
set by a screw to suit the flow. The aperture is formed lengthwise of
the reservoir, and at the bottom, so that the heavy portions of the ink or
colour which become precipitated are deposited upon the rotating
feeder or distributor, and from that direct upon the die in its travel.
My rotating ink or colour feeder or distributor is composed of a solid
body (in contradistinction to the hollow one described and claimed in
my former Patent already referred to) covered or coated with fibres
which receive and hold colour in quantity within them, and deposit it
upon the die and in the sunken portion when it comes into contact there-
with. The fibres are short and bushy, so that they become compressed
by the die, and enter all the deeply cut crevices and interstices or tracery
in the surface depositing therein an equal supply of colour, and without
risk of the colour being reabsorbed, as is the case from the use of
sponge, felt, or other absorbent body.
I therefore claim as part of my Invention the employment of one
or more short bushy fibre covered solid bodies for depositing ink or colour
upon the dies of relief printing presses. Plain rollers covered with
flannel or other similar body may however be employed.
In cach case
the roller or feeder is rotated, and fed externally.

of the said Letters Patent.
NOW KNOW VE that T the said John Couch de bonohu dealana

page_text: cularly to those described in reference to Sheet 2 of the Drawings
attached to the Specification thereof; and the objects are,-
Firstly. To arrange mechanism to relief stamping and printing
presses, whereby then can be operated by steam or other equivalent
power in lieu of by hand labour as at present employed.
Secondly. To provide the dies of such printing presses with an
automatic or a mechanical feed of ink or colour, the feed being regu-
lated continuously or intermittently by or through the main screw or
other working part of the press.
Thirdly. To produce a rotation of the ink or colour feeding or distri-
buting appliances in a direction reverse to that of the travel of the dies
in relief printing presses.
Fourthly. To combine with a rotating ink or colour distributor a
reservoir whose aperture is capable of being opened and closed at
pleasure.
Fifthly. To employ one or more rotating rollers or wheel brushes to
receive ink or colour upon the exterior, and to deposit it direct upon
the travelling dies of relief printing presses.
My Invention will be fully understood by the following description
and by the annexed Drawings:-On the head A of the main screw B,
Figures 1, 2, and 3 (which show the machine complete), I fit a deep or
broad toothed pinion C, which is geared into by a quadrant shaped
wheel D, whose spindle or shaft E is stepped into an arm F projecting
from the main standard G. The quadrant wheel D is in a piece with a
bevil pinion H, and it gears into another pinion I on a separate shaft J,
to which a reciprocating motion is imparted by one or more levers or
rods K in connection with a crank arm L or its equivalent. upon the
shaft M carrying the band or gut wheel N, by which the power is com-
municated from the prime mover. The band wheel N is loose the
upon
shaft M, and can be thrown into and out of gear by a clutch M¹, which
works upon a feathered portion of the shaft M, a fly wheel N¹ being
upon the shaft to ease and to steady the motion, as shown in Figure 1,
or it may be upon the screw A, as in dotted lines, Figure 3. The deep
toothed wheel C has a pin S dropped into a hole, and the end of it passes
5 into an aperture or fork of a plate T, which is in a piece with the pinion
(or a segment of a pinion) to ensure one gearing with the other while

page_text: Figure 12 is a detached view of portion of the head of a relief
stamping press with another of my improved modes of operating the
force plunger by steam or other equivalent power. Here the main
shaft carries a fast and a loose pulley; also a crank from which à forked
strap is hung, the lower end of the strap being connected to a nut or cross
head upon the vertical coarse-threaded rod for the purpose of rotating it
as the nut is lifted and depressed. The coarse-threaded rod is hollowed
for a distance up from its lower end, and thus receives a square or other
shaped end of the screw, which end is free to rise and fall in the hollow
according to the pitch and amount of rotation of the screw.
Another plan is shown in Figure 13. Here the crank strap is
attached direct to the "force" plunger for giving the impression, an
adjustable nut being upon the plunger to accommodate the nip or
pressure upon the paper which is between the force and the dic.
The action of the press, shown in Figures 1, 2, and 3, is as follows :-
The band upon the wheel N sets the whole in motion, paper in strip
being supplied from the reel a to the pad 6 after passing over and under
guide rollers c, d, and e through an intermittent action of the paul or
rod lever on the reel g striking against the pin h at every backward
travel of the die plate or slider i, the movement of the paper; being ter-
minated just before the arrival of the die k, so that at the actual moment
of wiping the die the paper j is stationary. The slider i continues to
travel to bring the die k under the feeder P for taking a supply of ink or
colour for the next printing, the die k going slightly beyond, so as to
be acted upon on the return over the whole of its top surface for the
proper distribution, the feeder having shifted its order of rotation
through the reverse action of its gearing for the reverse travel of
the die k under the control of the pinions 1, 1, and rack m through
the change of direction of rotation of the force screw and its driving
gear, as will be understood by an inspection of the Drawings. The
upper surface of the slider i, just where the die is fixed, is chanelled
or grooved for the overflow ink or colour to run down into a receptacle n,
which overflow, when sufficient has accumulated, can be poured out into
the reservoir Q. The paper j is received upon the reel g, and when this
is full the reel a is empty. The two reels are then removed from their
centre pins p, p', and the full one is placed over the pin p', which is
upon a vertical arm q of the press, and the empty one upon the pin p.
By this means the paper, which has been soiled on one side only by

page_text: wiping the die k is in a position for its other side or face to be utilized
for wiping purposes. In order that the waste ink or colour that may
be upon the paper should be perfectly dry before the paper is wound
upon the taking-up reel, I extend the arm out sufficiently, and fit a
roller & upon its end, so that by the time the paper has travelled the
roller 8, and passed on to the reel g, all gum or other sticky matter in
the ink or colour would have become dry.
The pinion T on the press head, as before spoken of, gears into an idle
or intermediate pinion t, which has a stop piece u upon it; and this stop
piece, which travels round with it at each rotation, takes into recesses
formed in the edge of the plate or disc T. In one instance the corner of
the stop piece takes into the recess, and then its rounded face rides
against the periphery of the plate Tas the plate T continues to complete
the last portion of its travel, that is, when the pressure of the force is to
be applied to the paper upon the dic, the motion of the dio having been
stopped by this slip movement of the stop piece, at which time also the
untoothed portion of the wheel or pinion T" is brought round for the
purpose of stopping the travelling motion of the die. On the return
movement or lift of the "force," and parts connected with it, through the
reciprocating action of the rod K, the first tooth of the wheel T takes
into the teeth of the idle wheel t, and then the stop piece turns until its
face bears against a shoulder of the plate T, and limits the travel of the
die k for the first feed, during that travel the various parts repeating their
duties again and again for every complete revolution of the main driving
shaft M.
In the Figures described I refer to a rotating cylindrical brush feeder
for taking a supply of ink or colour from a reservoir or from an inter-
mediate cup or spreader; and by the term cylindrical I mean brushes of
any round form that can be moved in a circular direction upon a pivot,
pin, or stud, or its equivalent (horizontal, vertical, or inclined), either
continuously in the same direction or intermittently in the same direction
or reciprocating, that is, partially in one direction and partially in the
reverse direction, which brush may however be only of a segment of a
cylinder, and the fibres short and bushy may be of hair, bristles, pre-
pared grass, bass, or other body of a similar character that can be used
for the purpose without having a tendency to scratch or otherwise injure
the face of the die over or against which it has to travel.

page_text: In some cases two of such bushy-like rotating brushes can be used,
one to clean the die on its way to the ink or colour feeder, and then as
the die returns the cleaner brush is mechanically moved up to be clear
of the die, and to prevent the ink or colour being removed before the die
arrives under the force plunger.
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,-
Firstly. The employment of steam or its equivalent power instead of
hand labour for operating the dies and other working parts of relief
stamping and printing presses, substantially in the manner and by the
means herein-before described and as shown in the Drawings annexed.
Secondly. The employment of apparatus, such as shown and hercin
described, by which an automatic or a mechanical feed of ink or colour
can be furnished to dies of relief stamping and printing presses, and
also by which the tracery and design or device upon or in the die can be
cleaned as well as fed, as set forth.
Thirdly. I claim the combination of appliances, as set forth, for
effecting a rotation of ink or colour feeders in or to relief stamping and
printing presses in a direction opposite to that of the travel of the dies,
whether the feeders travel at the same speed as the dies or at different
speeds.
Fourthly. I claim the ink or colour reservoir, as described and shown,
by which a regulated supply of ink or colour can be spread on or to
rotating or semi-rotating short fibred brushes, as and for the purpose
set forth.
Fifthly. I claim the employment and method of action of cylindrical
or equivalent shaped short fibred and bushy brushes fed upon the
exterior with ink or colour, which is to be afterwards supplied to dies of
relief stamping and printing presses, such short fibred bushy brushes
having a rotation imparted to them for the purposes described and sub-
stantially as shown.
. Sixthly. I claim the general combination of appliances or mechanism
described and shown with reference to Figures 1, 2, and 3 of the
annexed Drawings, the whole acting in the manner and for the purposes
set forth, whereby printing in ink or colour can be accomplished in
relief printing presses; also, the means of throwing a portion of such

page_text: appliances or mechanism out of gear for what is known as blind relief
stamping when such portion is worked by stoam or its equivalent power
instead of by hand labour.
In witness whereof, I, the said John Gough, have hereunto set
my hand and seal, this Thirteenth day of December, One thousand
eight hundred and seventy-three.
