PROVISIONAL SPECIFICATION left by the said Edwin Sturge at the Office
of the Commissioners of Patents on the 2nd March 1883.
EDWIN STURGE of 16 Allen Street Walworth in the Parish of Lambeth, and.
County of Surrey Engineer " IMPROVEMENTS IN MACHINERY OR APPARATUS FOR
STAMPING, EMBOSSING, AND COLORING IN RELIEF, ENVELOPES, OR OTHER REQUIRE-
MENTS
"
The mechanism by which I carry my invention into effect is as follows. For
the purpose of effecting the first motion of the machine hereinafter described I
provide a suitable frame of cast iron or other suitable material, and secured to a
table or bench, and on said frame is a radial arm of iron or other suitable material
bearing the steel die or creșt at or near it's extremity. This arm is caused by a
cam and lever connection working in an upright frame-to give alternate motion for
said arm, to traverse first from under the centre of the frame provided for containing
the inking or coloring given from the counterpart of the die, which portion only is
inked, to fit the engraved part of the said die, so dispensing with the wipeing of
the face of the die at each operation.
For the purpose of effecting the second action of the machine, the aforesaid
radial arm being caused to traverse, as described, in a segment of a circle, and
working on a guide to give steadiness to it's action is brought true, under the centre
of a lever-press provided for containing the counter part of the die for embossing, to
which is fed the envelope or paper to bear the relief stamping, or heading which is
guaged in the usual manner as may be required.
I propose to accomplish the coloring, or inking either by allowing the Brush, or
Felt-roller, or other means dipping into the color-receptacle to be provided with

page_text: an elastic spring of India-rubber, Gutta Percha or otherwise to take off superfluous
color, or else to place or fix a feeder or hopper containing the coloring matter at
an angle with a brush rotating against a roller receiving the coloring matter
on to it.
During the traverse of the lever-arm bearing the die, I arrange for perfectly
wipeing, and cleansing the face of the die after the inking or coloring matter has
been given to the engraved portion thereof, by employing a rotary table, or pad
(either one or more) working in an opposite direction to the die over which it, and
the radial-arm in it's to and fro passage at each operation is thoroughly cleansed,
the said table or pad being covered with a vulcanite, woollen, or other medium
suitable for the purpose.
For automatically working the embossing-lever I arrange or provide from the
main shaft a cam or eccentric working against a cranked-lever, or connected to the
ball-lever so as to cause it to give the required downward pressure, by means of an
ordinary quick patch-screw for stamping or embossing at the same instant when
the die and radial-arm are brought into position, and the return or upward action
is secured by ordinary springs of Indiarubber, steel, or other suitable metal.
In the case of the drum or roller containing a series of brushes, or arins radially
disposed I propose to give motion thereto by means of a band from the shaft and
so dispose it that it shall continuously ink or color the die until the lever-arm
comes into position when it is for the instant displaced and returned to re-charge
itself from an incline or other device fed by means of a hopper or receptacle
placed on said incline and adjustable for the color to flow easily thereto, and taking
a sufficiency of color to wipe or give into the engraved part of the die; or in a
somewhat similar manner by employing a feeder for the color giving same on to a
roller working over which I affix a drum or roller having a series of brush
arms taking off the color, from the roller first mentioned and giving same on to
the die.
The whole arrangement of mechanism is worked by means of two shafts placed
athwart the embossing and coloring standards, having a couple of spur or bevil
wheels, the upper shaft having a cam so arranged as to give a downward vertical
action to the counter die having a spring or springs to restore it's action ready for
the next motion. The lower shaft having a smaller wheel to accumulate power
and having a fly-wheel, and pulley for working by steam or other power, or in case
of foot-work, by means of any ordinary crank-lever connection and treadle
attachments.

by the said Edwin Sturge in the Great Seal Patent Office on the
1st September 1888.
EDWIN STURGE of 16 Allen Street Walworth in the Parish of Lambeth and
County of Surrey, Engineer "IMPROVEMENTS IN MACHINERY OR APPARATUS
" RELIEF ENVELOPES OR OTHER
FOR STAMPING, EMBOSSING, OR COLORING IN
REQUIREMENTS

For the better explanation of my said invention, I refer to the accompanying
drawings in which like letters refer to like parts throughout the several views,
Figure 1 is a sectional elevation of my invention on the line A B figure 2,
looking towards the stamping-press, with the bottom part of the table-frame,
and treadle broken off.
Figure 2-is a plan of the machine.
Figure 3-is a section of the machine on the line A B figure 2. looking towards the
inking apparatus, and showing the table-frame and treadle.
The mechanism by which I carry my invention into effect is as follows. For the
purpose of effecting the first motion of the machine I provide a suitable table or
bench a figure 1, to which I attach a radial arm b, figure 1, of iron or other suitable
material bearing the steel die or crest b¹ at or near it's extremity. This arm is
actuated by two pins 63, 63 fixed in the sliding-bar b*. reciprocal motion being given
to the sliding-bar by means of the rack 6, attached to the same, and the toothed
segment be working in said rack. By this mechanism alternate motion is given to
the said arm to traverse first from under the centre of the frame provided for con-
taining the inking or coloring given from the dabber c which only is inked to fit
the engraved part of the said die, so dispensing with the wipeing of the face of the
die at each operation. For the purpose of effecting the second action of the
machine, the aforesaid radial arm b being caused to traverse as described in a
segment of a circle and working on a guide b7 to give steadiness to it's action is
brought true under the centre of a press d provided for containing the counter-
part d', of the die 6', for embossing, to which is fed the envelope or paper to bear
the relief stamping or heading which is guaged in the usual manner as may be
required. On the toothed segment 66. there is a cam-piece. 68, which by it's contact
with the curved piece, 6º, secured to the side of the rack 65 prevents the spring
coming into action to return the radial-arm buntil the stamping operation is completed.
I accomplish the inking or coloring in the following manner. In a color receptacle e
I place the roller e', and in a sliding-frame, e³, I place a small inking roller e in
such a position that on reciprocating motion being given to the frame e the ink or
coloring matter is conveyed by said roller, ³, from the roller e¹ to the dabber c.
This reciprocating motion to the frame, e, is performed by the stud e, in the
wheel, f, acting on a cam-piece, es, on the sliding-frame, e², and by means of the
spring, e, which spring returns the sliding-frame, e, in one direction after it has
been operated on by the pin e. During the traverse of the radial-arm, b, bearing
the die, I arrange for perfectly wipeing and cleansing the face of the die after the
inking or coloring matter has been given to the engraved portion thereof, by
employing a rotary table, or pad f (or I may use more than one pad) working in
an opposite direction to the die over which the said pad passes, as the radial-arm
carries the die in it's to and fro passage at each operation, thereby removing any
superfluous ink from the die. The said pad, is covered with cardboard, or other
suitable medium for the purpose and is actuated by means of the band, f¹, con-
necting the pulley, f, on the top of the spindle f³, of the pad disk, f, with the
pulley f, on the shaft g. The inking roller, e¹, is actuated by means of the band e*,

page_text: connecting the pulley es, (on the spindle of the inking-roller, e¹,) and the pulley e,
on the shaft g, Requisite motion is given to the dabber c, by means of the cam c
which depresses the lever c², which, is restored to it's raised position by means of
the spring c³. For automatically working the press d, I provide from the shaft g, a
cam, or eccentric h, working against a lever h¹, and connected by the rod h², by means
of the spring h³, to the fly-wheel h*, on the top of the patch-screw d³, of the press d,
so as, to cause it to give the required downward pressure for stamping or embossing
at the same instant when the die, and radial-arm are brought into position
and the return or upward action is secured by the spring i, actuating the band i,
one end of which is attached to the spring i, and the other end to the sliding-
bar 6 in combination with the pulley 2, attached to the table a, In case I use a
drum or roller containing a series of brushes or arms radially disposed, I give
motion thereto by means of a band from the shaft in a similar manner to that
already described, and said roller is so disposed that it shall ink or color the die
until the radial-arm comes into position when the roller is for the instant displaced,
and returned to recharge itself from an incline or other device fed by means of a
hopper or receptacle placed on said incline, and adjustable for the color to flow
easily thereto and taking a sufficiency of color, to wipe or give into the engraved
part of the die, or in a similar manner by employing a feeder for the color,
giving the said color on to a roller working over which I affix a drum or
roller having a series of brush-arms to take off the color from the roller first
mentioned and to give the same color on to the die. The whole arrangement of
mechanism is worked by means of the upper shaft g, which shaft is actuated by the
lower shaft g', by means of the pinion j and wheel j₁ connecting them. The lower
shaft g', has the pinion ; to accumulate power and also a fly-wheel k. When steam
is employed I provide a pulley, and in case of foot-work the crank l, connecting
rod, and treadle attachments.
Having now fully described and illustrated my said invention I claim as secured
to me by the hereinbefore in part recited Letters Patent what is substantially
mentioned in the foregoing specification and illustrated in the accompanying
drawings. In Witness whereof I the said Edwin Sturge have hereunto set my
hand and seal this thirtieth day of August, in the year of our Lord one thousand
Eight Hundred and Eighty three.
