Year: 1853

page_text: LETTERS PATENT to Griffith Jarrett, of the City of London, for
the Invention of "IMPROVEMENTS IN MACHINERY OR APPARATUS FOR
STAMPING OR PRINTING COLORED SURFACES."
Sealed the 9th November 1853, and dated the 29th July 1853.
PROVISIONAL SPECIFICATION left by the said Griffith Jarrett
at the Office of the Commissioners of Patents, with his Petition,
on the 29th July 1853.
I, GRIFFITH JARRETT, of the City of London, do hereby declare the
nature of the said Invention for "IMPROVEMENTS IN MACHINERY OR
APPARATUS FOR STAMPING OR PRINTING COLORED SURFACES" to be as fol-
lows, that is to say:
I employ for the said purposes a stamping or printing press, in
which a piece of carbonic or other suitable colored paper is interposed
between the die or types & the paper or other material to be stamped
or printed in color, the said colored paper being secured by points or
otherwise on an open frame, which frame traverses under the die or
types; the stamping lever being connected with a crank motion, at the
end of which is a paul, which can be shifted so as to work a cog-wheel
at each ascent of the lever, either backwards or forwards, to the axis
or spindle of which cog-wheel is attached a screw, which screw works

page_text: either backwards or forwards (as the paul may be placed) the frame
carrying the carbonic or other coloring paper, so as constantly to bring
a fresh portion under the die or type, so as to ensure at all times a
perfect impression. In connection with apparatus for printing colored
surfaces I sometimes employ a modification of the said improvements.
in which I substitute, in lieu of the open frame carrying the carbonic
or other paper, a revolving ink roller.
I claim the employment of carbonic or other suitable colored paper
for stamping or printing in colors, in connection with my improved
apparatus, above described, for continually bringing a new portion of
such colored paper under the die or stamp; also the modification of my
apparatus, described, for printing with inks.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Griffith Jarrett in the Great Seal Patent Office,
on the 14th November 1853.
TO ALL TO WHOM THESE PRESENTS SHALL COME, 1.
GRIFFITH JARRETT, of the City of London, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-ninth day of July, in the year
of our Lord One thousand eight hundred and fifty-three, in the seven-
teenth year of Her reign, did, for Herself, Her heirs and successors.
give and grant unto me, the said Griffith Jarrett, Her special licence
that I, the said Griffith Jarrett, my executors, administrators, and assigns,
or such others as I, the said Griffith Jarrett, my executors, administra-
tors, and assigns, should at any time agree with, and no others, from
time to time and at all tinies thereafter during the term therein ex-
pressed, 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
OR APPARATUS FOR STAMPING OR PRINTING COLORED SURFACES," upon the
condition (amongst others) that I, the said Griffith Jarrett, by an in-
strument in writing under my hand and seal, 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

page_text: in the Great Seal Patent Office within six calendar months next and
immediately after the late of the said Letters Patent.
NOW KNOW YE, that I, the said Griffith Jarrett, do hereby declare
the nature of niy said Invention, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the
following statement (that is to say):
These improvements refer to an apparatus to be worked by the hand,
and adapted for the desk, counter, or writing table, by means of which
a colored mark or imprint may be produced upon a series of papers,
cards, or surfaces, without any interval of time being wasted between
the successive impressions, the stamping action of the machine bring-
ing continually a fresh supply of coloring matter to the die, which is
therefore always kept ready for employment. I prefer, in this appa-
ratus, to employ carbonic or other chemically prepared paper or mate-
rial for the purpose of producing impressions; the same apparatus
may, however, by a slight modification, be applied to those impressions
which are to be produced by ink or other coloring fluid. The appa-
ratus for carbonic or other colored and chemically prepared paper or
material is represented in the following Drawings, in which Fig. 1,
shows a vertical front view; Fig. 2, a side elevation; Fig. 3, an end
elevation; Fig. 4, a top or plan view, and Fig. 5, a longitudinal cleva-
tion. In cach Figure the same letters of reference denote similar
corresponding parts. A, A, the pedestal or stand; B, B, bracket arm
or standard; C, C, cylindrical head, for receiving and directing the
movement of the die C', or type fount; D, D, slide or 'pressure bolt,
working vertically within the cylindrical head, upon which the dic or
fount is fixed or secured by means of the tightening thumb screw E, E,
as shown; F, F, traversing frame, upon which the chemically prepared
paper or material is stretched or placed; G, G, the chemically prepared
paper or material; H, H, tightening screw, for attaching or detaching
the frame to insert or remove the said paper or material when required;
I, I, elastic bar or spring, by which the traversing frame, and the
chemically prepared paper or material, are kept up horizontally against
the die or fount, and allowed to yield to its pressure in <lescending;
K, K, screw for traversing the frame, working in hollow rectangular
earings L. L. cast or fitted to the stand or pedestal, as represented

page_text: more clearly in Fig. 5; M, M, revolving nut and wheel, capable of
moving in opposite directions, to give a backward or forward motion
to the screw, and a corresponding action to the frame; N, N, leather
pad or bed, upon which the die or type is pressed; 0, 0, metallic plate
for holding or retaining the same; P, P, the paper or surface for
receiving the print or colored impression; Q, Q, stamping or pressing
lever, formed or fitted with eccentric or cam head R, R, for giving the
required pressure to the die; S, S, slide or bolt head, hollowed out so
as to give a peculiar facility to the eccentric action of the cam R, R;
T, T, pin or stud, upon which the stamping lever works; U, U, lever
boss; V, V, spiral spring, for retaining the die in a reacting position;
W. W. curved motion lever, working on the centre X, secured to the
-fixed plate X: Y, Y, connecting link, uniting the stamping lever and
the curved motion lever, as shown; Z, Z. small shifting tappet or paul,
acting on the revolving nut wheel M, at intervals, consequent on the
raising or lowering of the stamping lever; (this tappet admits of
being turned or adjusted so as to take into the teeth on cither side and
actuate the nut and wheel in contrary directions, so as to give the
screw K, and frame F, a backward or forward motion. The methods
hitherto, practised (in ordinary stamping or embossing presses for the
purpose of producing colored surfaces) have consisted in employing
various descriptions of printing inks, applied in various known ways
to the surface of the die or type, the operation of which system, though
found by experience to answer the general purpose intended, has
nevertheless at all times been open to serious objections, from the
inconveniences incident upon the drying or caking of the ink, which
renders the production of a correct or satisfactory impression uncer-
tain. I therefore remark, that it is with a view to obviating the
inconveniences referred to, and rendering my apparatus more perfect
and complete, that I substitute for the printing inks heretofore em-
ployed the above-described chemically prepared paper or material,
which has first to be laid or strained upon a suitable frame, as repre-
sented, and then brought between the die or fount, as aforesaid, and
the paper or surface upon which the colored impression is to be taken;
the apparatus is then put in action by pressing down the die or type,
through the medium of the stamping lever in connection with the slide

page_text: or pressure bolt D. The die or type being thus caused to descend,
carries down the traversing frame and chemically prepared paper or
material, which is thus pressed against the paper or surface to be
printed or marked, producing a colored impression thereon, at the same
time that the short arm of the curved motion lever becomes elevated.
The impression being made, the stamping arm of the eccentric lever
is raised to its original position by the spiral spring V; the short arm
of the curved motion lever W, is then depressed, and the shifting
paul Z, pressing against the toothed wheel M, turns it partially round,
thus carrying forwards or backwards the screw K, and the frame F,
and exposing a fresh surface of the coloring paper or material to the
action of the die or fount, in readiness for the next operation. After
the frame has traversed its whole distance, its motion is reversed by
simply turning the tappet or paul Z, and so on, till the coloring matter
of the chemically prepared paper is exhausted, when a new piece must.
be inserted.
Having now fully described the nature of these my said improve-
ments, and in what manner I prefer to carry them into effect, I would
have it clearly understood that I by no means confine myself to the
precise details herein-before given, as the same may be varied without
departing from the general principle of my said improvements; but
that which I clain as new, and of my said Invention, is, firstly, the
construction and employment of a self-feeding, coloring, and stamping
apparatus or press, as above described; and, secondly, the application of
chemically prepared paper or material for obtaining colored impres-
sions, as described.
In witness whereof, I, the said Griffith Jarrett, have hereunto
set my hand and seal, this Twenty-ninth day of October, in
the year of our Lord One thousand eight hundred and fifty-
GRIFFITH JARRETT. (L.S.)
