page_text: LETTERS PATENT to Joseph Parkins, of Brewer Street, Golden Square,
in the County of Middlesex, Manufacturing Stationer, for the In-
vention of "IMPROVEMENTS IN MACHINERY FOR STAMPING, EMBOSSING, OR
PRINTING IN COLORS,"
Sealed the 4th May 1869, and dated the 9th December 1868.
PROVISIONAL SPECIFICATION left by the said Joseph Parkins at the
Office of the Commissioners of Patents, with his Petition, on the
9th December 1868.
I, JOSEPH PARKINS, of Brewer Street, Golden Square, in the County
of Middlesex, Manufacturing Stationer, do hereby declare the nature of
the said Invention for "IMPROVEMENTS IN MACHINERY FOR STAMPING, EMBOSSING,
OR PRINTING IN COLORS," to be as follows:-
The object of this Invention is to facilitate the operation of stamping,
embossing, or printing in colors note and other writing paper or
envelopes. To this end I construct an oblong frame and fix it at one
end to an ordinary stamping machine and bevil off its inner edges.
so as to form V guides on which the die bed slides. Sliding on this
oblong frame is another and smaller one, which receives a reciprocating
or forward and backward motion from the die bed. On the sides of
this second frame are two wedge-shaped cams, which in its forward
motion raise another frame sliding in upright standards and carrying

page_text: an adjustable india-rubber cushion, so that the die may pass without
touching. This cushion presses a band of paper on to the die as it
passes under it in its backward motion to clean it from the superfluous
ink. The requisite amount of pressure is given to this cushion frame
by means of a rod tapped at its lower end projecting from the under
side through the oblong frame and descending a sufficient depth to
allow of a helical spring being applied to it, the tension of which is
regulated by a screw nut. The inking apparatus is attached to one
of the upright guides of the cushion frame (which also carries rollers
to facilitate the onward intermittent motion of the die cleaning paper
band), and consists of a reservoir for holding the ink, to the lower end
of which a brush or other equivalent device is attached. In the bottom
of this reservoir are a hole or holes which by means of short tubes allow
the ink to flow down into the brush; in order to regulate the flow of
ink small conical pins fixed to a plate are inserted into the mouth of
these holes, and are raised or lowered by means of a vertical screw, so
that a larger or smaller quantity of ink is allowed to pass into the
brush as required. In order to properly actuate the die cleaning paper
band and cause an intermittent progressive motion, so that the die
should not press against it twice in the same place, there are nipping
rollers, between which the band passes. These rollers are by preference
covered with vulcanized india-rubber, and are actuated by a rack and
pinion and click and ratchet motion which are actuated by the recipro-
cating frame. The length of stroke of this rack and pinion is regulated
by means of an adjustable tappet on a rod extending from the sliding
frame. Scrapers or doctors are adapted to some of the rollers to keep
them clean and prevent the inked paper from sticking thereto. The
necessary power to cause the reciprocating motion of the die bed may
be given by means of a treadle and weights or other suitable
arrangement.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Joseph Parkins in the Great Seal Patent Office on.
the 9th June 1869.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOSEPH
PARKINS, of Brewer Street, Golden Square, in the County of Middlesex. 3
Manufacturing Stationer, send greeting.

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
MACHINERY FOR STAMPING, EMBOSSING, OR PRINTING IN COLORS," upon the
condition (amongst others) that I, the said Joseph Parkius, my
executors or administrators, 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 imme-
diately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Joseph Parkins, do hereby declaré
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, reference being had to the Drawing hereunto
annexed, and to the letters and figures marked thereou (that is to
say):-
The object of this Invention is to facilitate the operation of stamping,
embossing, or printing in colors note and other writing paper or
envelopes.
In the accompanying Drawings, Fig. 1 is an elevation and Fig. 2
a plan view of my improved machine; Fig. 3 is a sectional clevation,
and Fig. 4 a plan view, of the inking or coloring apparatus detached.
A is an oblong metal frame fixed at one end to an ordinary stamping
machine X and bevilled off on its inner edges so as to form V guides
on which the die bed B slides. This die bed consists of a steel or
other metal block having a hole in it for the reception of the die 1.
A small trough a¹ is attached to the inner side of the die bed to catch
the superfluous ink that will be caused to flow, round and down the

die by the sharp edge of the die coming in contact with the brush 2
of the inking apparatus. Sliding on this oblong frame A is another and
smaller metal frame C that receives a reciprocating or forward and
backward motion from the die bed B, which is actuated by means
of the cords x, z, which are acted upon by a treadle and weight not
shewn in the Drawing, or by any other suitable mechanical arrange-
On the sides of this second frame C are formed two vertical
wedge-shaped cams D which as the frame C and die bed B are moved
to the right in order to bring the die 1 under the inking brush 2 will
support the cushion or impression frame E out of the way, so that

the die 1 may pass forward without touching it.
of two side pieces connected together at top by a cross plate, and sliding
in upright standards F, F¹, and carrying an india-rubber cushion. The
cushion e¹, which is shewn by dots in Fig. 1, consists of a small block
of wood covered with india-rubber and fastened to a metal plate e2.
A band of paper a, shewn in red in Fig. 1, passes under the cushion,
and when the die 1 returns to the press the cushion presses down the
paper a on to the die and thereby cleans it from the superfluous ink.
I prefer to make the block of wood with a corrugated surface in order
that the edges of the die may be properly cleaned. The requisite
amount of pressure is given to this cushion frame by means of rods G
tapped at their lower ends and projecting from its under side through
the oblong frame A, and descending a sufficient depth to allow of a
helical spring being adapted to them, the tension of which is regulated
by a screw nut. The elastic cushion is made adjustable, so that when
a larger or smaller die is used the cushion may be raised or lowered.
This will be done by means of screws e, e, working through the top
plate of the cushion frame E, and rivetted or otherwise fastened to
the metal plate of the cushion. The inking apparatus is attached
to an adjustable cross piece f fixed to the upright guides F1 of the
cushion frame. These uprights F1 also carry rollers b, b', to facilitate
the onward intermittent motion of the die cleaning paper band a. The
inking apparatus, which is shewn detached and drawn upon an enlarged
scale at Figures 3 and 4, consists of a reservoir or cylinder H for holding
the ink. To the lower end of this cylinder a brush 2 or other
equivalent device is attached in any suitable manner; in the bottom
of this reservoir or cylinder H are holes, the number varying according
to the dimensions of the brush 2. Or a slot may be cut across the
bottom of the cylinder or reservoir H, and by means of a short tube

page_text: or tubes the ink will be allowed to flow down into the brush 2. In
order to regulate the flow of ink into the brush small conical pins or
V pieces c, c, fixed to a plate d are inserted into the mouth of these
holes, and are raised or lowered therein by means of a vertical screw e
connected to the plate d, and working through a cross piece d'fitted
to the upper end of the reservoir or cylinder, so that by merely turning
the screw e a larger or smaller quantity of ink may be allowed to
pass into the brush as required.
arrows.
In order to properly actuate the die cleaning paper band a and
impart an intermittent progressive motion thereto, so that the die should
not press against it twice in the same place, I employ two nipping
rollers I, I, between which the band a passes in the direction. of the
These rollers are by preference covered with vulcanized india-
rubber, and are actuated by a rack g and pinion h, the latter being
mounted on the shaft i of the nipping roller I¹. A click and ratchet
is adapted to the axle or shaft i, the whole being actuated by the recipro-
cating sliding frame C. The length of stroke of this rack and pinion
is regulated by means of an adjustable tappet or block j on a rod k
attached to and extending from the sliding frame C. The nipping
roller I is composed of two small rollers mounted on the same shaft i,
and working together and having between them a small pulley 1, Fig. 2,
running loosely on the shaft to act as a guide for the treadle cord X.
In order to keep the nipping rollers I, II, at proper tension and in
position I employ an elastic band K and stretcher K¹ provided with
hooked ends, whereby it is attached to the ends of the shaft of the
roller. I. Scrapers or doctors are adapted to some of the rollers to keep
them clean and prevent the inked paper from sticking thereto.. In order
to prevent the nipping rollers from rotating in the wrong direction I
adapt on the shaft i, and at the opposite end of the roller I¹, a ratchet
wheel and spring.

The mode of perating the machine is as follows:-Upon pressure
being applied-from the treadle to the cord x, the bed plate B will be
drawn forward or to the right until it strikes against the rear end of
the sliding frame C; it then continues its forward motion with the
sliding frame C until it is clear of the inking or color brush 2.
the same time that the die passes under the cushion frame E, the
elastic cushion el will be held up by the wedge-shaped cams D, but
as the frame C will be moved forward with the die bed B it will be
At

page_text: evident that as soon as the die 1 arrives under the brush 2 the cushion
frame e will fall. On the pressure being removed from the treadle
cord the die bed B will be drawn back, that is, to the left, to the front
end of the frame C by the weighted cord 2, and will thus pass under
the elastic cushion e¹ to the stamping press, but as the elastic cushion e¹
will not then be held up by the cams D the die 1 will press against
the paper band a, and the superfluous ink will be thereby wiped off
therefrom. The sliding frame C will continue to be drawn back by
the die bed B until the cams D again come into operation and raise
the cushion frame E out of the way of the die ready for the next
inking operation. The paper band a (which is wound on a drum or
other suitable device fixed under the table) passes over the rollers 6 in
the direction of the arrows and under the elastic cushion E, as shewn
in red, and from thence over the rollers 6 to the nipping rollers I, I¹.
The clean die with its proper supply of ink having been brought under
the stamping press the paper is placed thereon and the impression given
in the ordinary way.
Having now described the nature of my Invention, and having
explained the manner of carrying the same into effect, I claim as the
Invention secured to me by the above in part recited Letters Patent,
the application to machinery for stamping, embossing, or printing in
colors of the devices or apparatus herein set forth for inking or
coloring and cleaning the die.
In witness whereof, I, the said Joseph Parkins, have hereunto set
my hand and seal, the Eighth day of June, in the year of
our Lord One thousand eight hundred and sixty-nine.
