We CAROLINE NEWMAN BINTCLIFFE and HARRY NEWMAN PARKINS, trading as
Joseph Parkins & Company of 17, Greek Street, Soho, in the County of Middlesex,
Manufacturing Stationers do hereby declare the nature of this invention to be as
follows:-
The object of this invention is to facilitate the stamping or embossing or printing of
monograms, coats of arms, legends, addresses, or other matter, in colors, on note or
other paper, cards, and envelopes.
In carrying out our invention, we may employ a screw stamping or embossing press
of the ordinary construction, and we adapt thereto certain mechanism for reciprocating
the die, inking the same, and removing the superfluous ink.
The die bed of the press is faced perfectly true, and to the bed is secured, by one
end, a rectangular frame of some length, the side pieces of which form guides on
which slides a die box. The underside of this die box is faced perfectly true to
correspond with the die bed, and the upper side is slightly inclined so that the face of
the die may be slightly inclined, to enable it to pass with facility under a cleaning
paper, and prevent its sharp corner cutting the paper band. The die box is arranged
with respect to the die bed so that it will slide onto, and rest upon the bed during the
stamping operation, thus providing a perfectly firm and solid bed upon which to
stamp.
The die box receives a reciprocating motion by means of a treadle and weight, to
which it is attached by chains passing over guide pulleys placed at opposite ends of
the frame, the forward motion being caused by the attendant pressing down the
treadle, and the return motion by the weight.
The movement of the. die is necessary to bring it under a coloring mechanism,
whereby the color is laid on the die, and under a wiping mechanism, whereby the
superfluous color is wiped off the face of the die.
The coloring may be effected during either the forward or return motion of the die,
but the wiping or cleaning operation most conveniently takes place during the return
motion

page_text: The coloring mechanism may consist of a hopper-shaped reservoir provided at its
exit with self-closing lips arranged to open on coming into contact with the die, and
allow a small quantity of color to escape.
One lip may be longer than the other, to sweep the color into the sunk portions of
the die, and it will also serve to some extent as a "doctor," to wipe off the superfluous
color from the face of the die.
The coloring mechanism may be mounted so that it may be raised out of contact
with the die during either its forward or return movement. The wiping or cleaning
mechanism may consist of a band of paper, which is passed under an elastic and
adjustable pad, and against which the face of the die comes in contact during its
return movement. This pad may be carried in a frame capable of sliding in vertical
guides attached to the main frame, and held down by springs which give the required
pressure to effect the cleaning of the die face.
The pad itself may be adjusted according to the height of the die, by means of an
adjusting screw, the ends of the pad being maintained in position by springs.
The cleaning pad will be raised out of contact with the die during its forward
movement by means of cans suitably arranged for the purpose.
In some cases, we may mount the coloring mechanism and the cleaning mechanism
at opposite ends of an oscillating frame mounted in uprights attached to the main
frame, and which serve to carry guide rollers for the band of paper, the rocking of
this frame being effected by cams as the die box reciprocates.
An intermittent progressive motion is communicated to the band of paper either at
the time the die is passing under it, or afterwards, by means of nipping rollers
actuated by a rack and pinion, pawl and ratchet, tappet, or other suitable arrange-
ment, set in motion by the reciprocating die bed, or in any other convenient
manner.
In addition to the cleaning band, we may use a cleaning brush to remove any excess
of color in the sunk portions of the die.
The machine may of course be worked by steam, hydraulic or other power, when
available, instead of by hand, and either direct, or through a convenient arrangement
of gearing, the several operations of coloring, wiping, and stamping being properly
timed. In this case, a plunger working in a cylinder might be substituted for the
screw of the stamping press.

We CAROLINE NEWMAN BINTCLIFFE, and HARRY NEWMAN PARKINS, trading as
Joseph Parkins and Company, of 17 Greek Street, Soho, in the County of Middlesex,
Manufacturing Stationers, 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 :-
The object of this invention is to facilitate the stamping or embossing or printing of
monograms, coats of arms, legends, addresses, or other matter, in colors, on note or
other paper, cards, and envelopes.
In the ordinary process of stamping, embossing, or printing note paper in colors,
the die has to be taken out of the press to be inked, and to have the superfluous ink
rubbed off, and is then put back in the press for the stamping or printing operation.
This mode of procedure is necessarily slow however skilful the operator may be, and
many attempts have been made to produce a machine by means of which the work
may be effected more speedily than heretofore, but hitherto without practical
results.
Now our invention consists in improved machinery for stamping, embossing or
printing in colors, by the aid of which these operations may be carried out effectually
and with considerable speed.
In carrying out our invention, we employ a screw stamping or embossing press of
the ordinary construction, and we adapt thereto certain mechanism whereby the die
may be reciprocated to receive the color, and the superfluous color may be removed
before the printing or stamping operation takes place.
In the accompanying drawing,
Fig. 1 is a longitudinal section of our improved machine.
Fig. 2 is a plan view of the wiping pad mechanism and the die box, and
Fig. 3 is a diagram showing the means for working the machine.
A is a screw press, the part A' forming the die bed, which is faced perfectly true.
Secured on the die bed A¹ by one end is a rectangular frame B, the sides of which
are formed with V-guides on their inner edges. Sliding in this frame is a second
frame C, which we will term the "cam frame," the sides being formed with cams (¹
for a purpose to be presently explained. D is the die box which works within the
frame C and between the V-guides of the frame B. To opposite ends of the die
box D, chains or cords D1 D2 are attached, D' being connected with a treadle D³,
and D2 carrying a weight D (see diagram Fig. 3). The die box is drawn by
depressing the treadle into the position shown in Figs. 1 and 3, so that the die may be
supplied with color, and it is returned to its normal position under the press (shown
dotted in Figs. 1 and 3) by the weight.
The die box consists of two parts D D*, and the underside of the lower part D* is
faced perfectly true to correspond to the die bed, onto and upon which it is arranged

page_text: to slide and rest for the stamping operation; thus, all strain on the ✓ guides is
obviated, and a firm and solid bed is provided upon which to stamp ; a point hitherto
overlooked in most machines of this class.
The division of the die box into two parts permits of the press being used in the
ordinary manner without the wiping mechanism, as the upper part D, with the die,
can be readily taken out to wipe off the superfluous color, and put back again for the
stamping operation, the upper part being steadied in position by the pins E2 of the
plate E', which project into the lower part D* of the die box.
E is the die, which is conveniently secured to a plate E', which fits into the upper
part D of the die box. This plate, it will be seen at Fig. 1, is steadied in position by
pins E, and is slightly taper, so that the face of the die will be slightly inclined from
a horizontal line. This is an important feature in our improvements, inasmuch as it
has been found hitherto that the sharp edge of a perfectly level die cuts the paper
cleaning or wiping band as it strikes it, and renders the continuous working of the
machine impossible.
By setting the die at a slight inclination, the face of the die, rather than the edge,
first strikes the paper band, and thus all tendency to cut the band is obviated, and
perfect and continuous work is ensured.
This mode of setting the die necessitates an elastically mounted cleaning or
wiping pad.
F is the pad, which consists of a wood block covered with india rubber, and secured
to a metal plate F¹. To this plate is suitably connected a thumb screw G, which
works in a cross plate forming part of a frame H, the side pieces of which slide in
vertical standards secured to the frame B. This frame is provided internally with
shoulders, and it is held down by the springs I mounted on rods pendent from the
frame in a manner which will be well understood. Between the plate F' and the cross
plate H, we arrange springs F2, which are retained in position by the screws or
pins F³, which pass through the cross plate H.
The amount of pressure of the pad on the die is regulated by the central thumb
screw G, while the springs F2 allow the pad to accommodate itself to the inclined
face of the die.
J is the cleaning or wiping paper band, which passes from a roll over suitably
placed guiding rollers, and under the pad F, from which it is led away over guide
roliers to a pair of gripping rollers K, to which an intermittent motion is given in any
convenient manner, either as the die is returning to its normal position under the
press, or as it completes its forward movement to receive the color, so that a clean
portion of the paper may be presented each time to the die.
The operation of the machine is as follows:-The die has been drawn forward (by
depressing the treadle) into the position shown at Fig. 1, to have the color applied,
which is done by the attendant with a brush. When the foot of the attendant is
removed from the treadle; the weight causes the die box to travel back. As the die
comes under the paper band, the superfluous color is wiped off by the band, and the
die is left perfectly clean. As the die box continues its backward motion under the
influence of the weight, it strikes against the end of the cam frame C, which is also
drawn back. This movement causes the cams C¹ to come into contact with the
shoulders on the frame H, which frame is thus raised clear of the die on its forward
stroke.
After the stamping is effected, the die is again drawn forward by depressing the
treadle, and the die box striking the opposite end of the frame C, carries it forward
until the cams Care clear of the shoulders of the frame H, but this will not take
place until the die is also clear of the pad. The frame H will then descend under the
influence of the springs I, and the pad will be again in the path of the die, to wipe off
the superfluous color on its return movement.
L is an adjustable guide attached to the plate F1, which serves to keep the paper
band in its proper position in the path of the die.
We would here remark that the general construction of the machine above referred
to is well known, and further description thereof is unnecessary.

page_text: Our improvements have rendered this machine in every sense a practical success,
which before was not successful.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is:
