Improvements connected with Relief Printing and like
Stamping Presses.
We, JOSEPH RICHMOND, and WALTER WHITING, both of 30 Kirby Street,
Hatton Garden, County of London, Engineers, do hereby declare the nature of
this invention to be as follows :-
This invention relates to certain details of construction, arrangements, positions,
and method of operating the various parts of relief printing, and like stamping
presses, whereby large, or comparatively large, or small dies, plates, blocks, or
other printing surfaces may be reciprocated, be inked effectually, be wiped, or
cleaned, and the impression imparted to paper, or other material, operations being
mechanically performed in regular sequence from a main shaft driven by steam, or
other power.
The press is composed of a bed in or connected with which is a main shaft
carrying a grooved cam for the bowl of a counterbalanced lever to work in. This
cam has certain rises and drops in it, and the long, or unweighted end of the lever
has a swivel socket nut in it for the attachment of wire ropes, or chains which lead
round guide pullies, and are connected to a sheave or sheaves on the head of the
press screw for effecting the necessary up and down motion of the "force."
The pullies, or some of them are supported by a pillar, which has projecting
arm, serving also as a stay to the press head to prevent vibration and to steady the
machine while at work.
The head of the press has a toothed wheel, which is rotated, and by its gearing
into a pinion on a spindle and other gear working into a rack, the die, or printing
plate carrier is moved to and fro on the bed for the die, or plate to be inked, and
for the transfer. The inking is effected by a brush which takes its supply from a
duct, or inking roller during the reciprocating action of the carrier, and it is, when
the die, or plate is under the brush, that the effectual inking takes place by short
reciprocating motions imparted to the carrier by the cam through the lever, and
parts actuated therefrom.
The wiping or cleaning the die is by a reel of paper, or the like, the reel being
operated by a pin and drop pawl at each motion of the carrier for bringing fresh
parts of the reel into position for the purpose.

Improvements connected with Relief Printing and like
Stamping Presses.
We, JOSEPH RICHMOND, and WALTER WHITING,. both of 30 Kirby Street,
Hatton Garden, County of London, Engineers, do hereby declare the nature of
this invention and in what manner the same is to be performed to be particularly
described and ascertained in and by the following statement :—
This invention relates to certain details of construction; arrangements, positions,

page_text: and method of operating the various parts of relief printing and like stamping
presses, whereby large, or comparatively large, or small dies, plates, blocks, or
other printing surfaces may be reciprocated, be inked effectually, be wiped or
cleaned, and the impression imparted to paper, or other material, the whole of the
operations being, mechanically performed in regular sequence from a main shaft
driven by steam, or other power.
The press is composed of a bed, in or connected with which is a main shaft.
carrying a grooved cam for the bowl of a counterbalanced lever to work in. This
cam has certain rises and drops in it, and the long or unweighted end of the lever
has a swivel socket nut in it for the attachment of wire ropes or chains which lead
round guide pullies and are connected to a sheave or sheaves on the head of the
press screw for effecting the necessary up and down motion of the "force."
The pullies or some of them are supported by a pillar which has a projecting
arm serving as a stay to the press head to prevent vibration and to steady the
machine while at work..
The head of the press has a toothed wheel which is rotated, and by its gearing
into a.pinion on a spindle and other gear working into a rack, the die or printing
plate carrier is moved to and fro on the bed for the die or plate to be inked, and for
the transfer. The inking is effected by a brush which takes its supply from a duct
or inking roller during a repeat reciprocating action of the carrier, and it is when
the die or plate is under the brush that the effectual inking takes place by
short reciprocating motions (repeats) imparted to the carrier by the cam through
the lever and parts actuated therefrom.
The wiping or cleaning the die is by a reel of paper, or the like, the reel being
opérated by a pin and drop paul at each motion of the carrier for bringing fresh
parts of the reel into position for the purpose.
:
The invention will be more clearly understood by the annexed drawings and the
following description.
Figure 1 is an elevation of the cam and lever mechanism as we prefer to apply
them.
Figure 2 is a perspective elevation of the complete machine.
Figure 3 is a detached view of the gear mechanism by which the reciprocating
motion. of the rack is obtained.
The machine for relief printing. is well known as the "Gough" relief printing or
stamping press, and has been operated by hand. Our present invention is the
application of appliances to enable such machine to be operated by steam, or other
engine power, and also to enlarge the several parts for the purpose of effecting the
relief printing, or relief stamping from larger plates, dies, or blocks than is possible
by the present hand operating press, although such improved machine is capable
of printing from small plates, as well as from large ones.
The machine consists of a base A affixable to a table, said base A is grooved
and fitted with carrier B upon which the engraved plate it is desired to obtain
impressions from is fixed in. any suitable manner. At the extreme end of an
arm C, projecting from the carrier B, is fixed an inking or ductor roller E
which, during its inward movement, rubs the surface of the brush G, and
supplies it with a sufficient quantity of ink that is in turn imparted to the
surface of the engraved plate fixed upon the carrier B. F is a pad and H is
a narrow strip of paper passing from the reel I under and over guide rollers J, J,
beneath the before mentioned pad; F, thence under, over, and around the guide
rollers K, K, K, to the receiving reel L, which is at every outward movement
of the carrier B caused to revolve a portion of a revolution by means of the
stud M, weighted lever N, paul P, and ratchet wheel Q, affixed to the reel L.
By this means, a clean or dry piece of paper is interposed between the
engraved plate, and the pad F. to remove the superfluous ink from the surface of
the engraved plate during its inward movement beneath the pad after having
been inked by the brush G at its extreme: outward travel. The necessary
movement of the carrier: B and ductor roller. E is obtained by the quadrant R

page_text: through the pin S engaging in a hole of the collar T which is in a piece with
the quadrant R and by means of the gear wheels U, V, shaft W, wheel X
gearing with the rack Y the semi-rotary movement imparted to the pullies Z
is transmitted and converted to the rectilinear movement of the carrier B. In
order that the carrier B may be at rest and immovable during the printing
operation, the quadrant R becomes disengaged from the pinion U, whereby any
accidental movement of the gear wheels U, V, X, rack Y, and carrier B
(during the descent of the stamp A' upon the paper to be printed which is
inserted between said stamp A' and the engraved plate upon the carrier B),
is prevented.
B₁ and Care two powerful springs to counterbalance the weight of the stamp A¹.
To prevent any undue shock damaging the first entering tooth of the quadrant R,
a stop pin or lug D' is provided and adapted to abut against the plate E' at the
instant the quadrant R is about to engage the pinion U as represented at Figure 3,
which shows the plate E', and lug D, pinion U, and quadrant R just engaging to
operate the rack Y in the manner before described. The recess F1 in the collar T.
allowing the plate E to move upon its axis.
The head of the screw carries a couple of sheaves Z to which wire ropes or chains G'
are secured by bolts and pinch nuts H', H', said ropes G¹ are led over guide
pullies J, J, down to a single wheel K, the ends of the wire rope or chain being
connected to a swivel socket joint L' and kept taut by the barrel spring M¹. The
swivel socket joint L' is attached to the long arm of a lever N¹ which is centred
by a short shaft to a boss of the bed plate P, its free end carrying a weight Q¹ to
counterbalance it.
The long arm N' has a bowl R' riding in the groove S¹ of a cam T¹ which is
on the main shaft U' and receiving its motion by a countershaft V₁ and gear
wheels W, X. The main shaft U' is fitted with an ordinary friction clutch which
can be put in and out of gear by the rod Y₁ and pedal lever Z', said pedal lever
being so arranged that on either side being depressed by the foot of the operator,
the working can be easily thrown in and out of gear and remain so until the other
foot pedal is operated upon.
The guide pullies J', J', are carried by an arm A" projecting from a pedestal B"
fitted at the rear of base plate, or table C", and its upper end carries a bracket D",
the front end of which coincides with the screw shaft E" or press head F
through the collar G" of said bracket D" the press head F" passes.
His a fly wheel by which the momentum is given and motion is steadied.
The action of the machine is as follows:-The foot pedal on one side being
depressed throws the clutch into gear with the main shaft U', this carries the
cain T round with it, and the bowl R¹ by working in the cam groove S₁ causes
the lever N to move up and down upon its pivot J", and so draw or pull the
rope G', as desired, this causes the sheaves Z to rotate the screw E" and fly
wheel H which by being connected to the collar T by the rod S moves the
plate E' and quadrant R to cause a rotation of the pinions U, V, to move the
rack Y along, say, to the right of the machine where the engraved plate passes
under the brush G, the nose K" of the cam groove S' causing a reciprocating
action of the carrier and the plate, so that the plate is supplied with ink by such
reciprocating action before it i.e. the rack Y and plate L" passes back towards the
force," the plate L" being wiped by the paper H to leave it clean while passing
under and remaining at rest under the "force," for the printing to be effected.
66
On the engraved plate approaching the "force," the ductor or inking roller E
passes under the brush, and supplies it with a fresh quantity of ink or colour, so
that for the next return movement, the plate is again inked by the brush by the
reciprocating action of the rack due to the formation of the nose K" and the cam
groove S, a fresh piece of wiping paper being drawn from the upper reel at each
to and fro movement of the rack by the studs M, M, engaging the lever N of the
take-up reel L.
