PROVISIONAL SPECIFICATION left by the said Griffith Jarrett at the
Office of the Commissioners of Patents, with his Petition, on the 10th
June 1857.
I, GRIFFITH JARRETT, of the City of London, Engraver and Press Manu-
facturer, do hereby declare the nature of the said Invention for "IMPROVEMENTS
IN APPARATUS FOR PRINTING OR ENDORSING IN COLOURS ON PAPER OR OTHER SURFAces,
BEING IMPROVEMENTS UPON THE INVENTION SECURED TO ME BY LETTERS PATENT,
DATED THE 29TH DAY OF JULY 1853,'" to be as follows:--
This Invention relates to improvements upon the subject matter of certain
Letters Patent, granted to me by Her present most Excellent Majesty,
bearing date the Twenty-ninth day of July, in the year of our Lord 1853.
The object of the present improvements is to render the working parts of
the press more compact and durable, and less liable to become injured by
accident than heretofore. The vertical slide which carries the die or type for
giving the imprint is operated by a cam lever as heretofore, being returned

page_text: into a reacting position by a lever acted upon by an india-rubber or other
elastic spring, the die being attached to the lower end of the slide by a taper
dovetailed key. Immediately above the die the slide carries two brackets,
which support two small rollers, around which is passed an endless band or
ribbon of silk or other suitable woven or infrangible material carbonized or
otherwise suitably prepared with coloring matter, one or both of these brackets
is or are capable of being adjusted for the purposes of removing, replacing,
and distending the endless band or ribbon when required, and fixed by means
of a set screw. One end of one of the rollers is furnished with a ratchet
wheel, which is acted upon by a pall (attached to the frame of the press) in
such a manner as to advance the endless band or ribbon slightly at every
movement of the press so as to continually present a fresh surface to the action
of the die or type.
The impression pad or counterpart is also made capable of easy adjustment
and renewal when required, being formed, of a plain piece of leather or other
suitable material bevilled at the edges and slipped, horizontally between two
metal slides baving their edges. similarly. bevilled and placed parallel to each
other, or nearly so.

the Channel Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN
APPARATUS FOR PRINTING OR ENDORSING IN COLORS ON PAPER OR OTHER SURFACES,

page_text: "BEING IMPROVEMENTS UPON THE INVENTION SECURED TO ME BY LETTERS PATENT,
DATED THE 29TH DAY OF JULY 1853,'" upon the condition (amongst others) that
I, the said Griffith Jarrett, my executors or administrators, by an instrument
in writing under my, or their, or one of their hands and seals, should par-
ticularly 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 immediately
after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Griffith Jarrett, do hereby declare
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 in writing, and on reference to the accompanying Drawings, that is
to say:
This Invention relates to improvements upon the subject matter of certain
Letters Patent granted. to me by Her present most Excellent Majesty, bearing
date the Twenty-ninth day of July, in the year of our Lord One thousand
eight hundred and fifty-three.
The object of the present improvements is to render the working parts of
the press (for printing in colors without the use of fluid inks) more compact
and durable, and less liable to become injured by accident than heretofore.
The vertical slide which carries the lie or type for giving the imprint is
operated upon by a cam lever as before, being returned into a reacting position
by a lever acted upon by an india-rubber or other elastic spring, the die or
type holder being attached to the lower end of the slide, by means of a taper
dovetailed key. Immediately above the die or type holder the slide carries
two small brackets supporting two rollers, around which is passed an endless
band or ribbon of silk or other suitable woven or infrangible material, car-
bonized or otherwise suitably prepared or saturated with coloring matter.
One or both of these brackets is or are capable of being adjusted for the
purpose of removing, replacing, and distending the endless band or ribbon
when required, and may be fixed when adjusted, by means of a set screw or
screws. One end of one of these rollers is furnished with a ratchet wheel, which
is acted upon by a pall (attached to the frame of the press) in such a manner
as to advance the endless band or ribbon slightly at every movement of the
press, so as continually to present a fresh surface to the action of the die
or type.
The impression pad or counterpart is also made capable of easy adjustment
and renewal when required, being formed of a plain piece of leather or other
suitable material bevilled at the edges and slipped horizontally between two-

page_text: metal slides having their edges similarly bevilled and placed parallel to each
other, or nearly so.
Such being the nature and object of my said improvements, I will proceed
to describe more in detail the manner of carrying the same into practical
effect; and in order that the same may be perfectly understood, I have annexed
hereunto a Sheet of Drawings illustrative thereof, and have marked the same
with figures and letters of reference corresponding with those in the following
explanation thereof, similar letters indicating the same parts in the several
Figures.
Figure 1 represents a side elevation of my improved endorsing press for
printing in colors without the use of fluid inks; Figure 2 is a front view of
the same; and Figure 3 is a longitudinal section taken vertically through
about the centre of the press, shewing the same in the act of giving the
imprint.
a, a, is the bed plate or stand of the apparatus; b, b, the standard or
bracket. The head of this bracket is provided with vertical grooves in which
the slide c, c, moves, being kept in its position laterally by the heads of the
screws ; d, d, is the cam lever for giving the imprint; and e, e, is a
lever moving on a pin at f. One end of this lever e takes into a hole in the
slide c, c, and to the other end of the lever an india-rubber or other suitable
spring 9, 9, is attached. This lever and spring are for the purpose of returning
the slide and cam lever into a reacting position after each impression; h, h,
are brackets carried by the slide c, c, and capable of being adjusted and fixed
therein by means of the screws i, i. These brackets carry small rollers k, k,
round which passes the endless band or ribbon l, l, which is suitably prepared
with coloring matter. One of the rollers k is furnished with a ratchet wheel
m, which is acted upon by the pall n, so as to advance the band or ribbon l
slightly as the slide c rises after each impression. 0, 0, is the die or type
holder, which is attached to the lower part of the slide c, c, by means of a
dovetailed taper key p, p. The impression pad or counterpart q, q, is formed
of a plain piece of leather bevilled at the edges, and slidden horizontally
between the metal slides r, r. The action of the apparatus is as follows:-
The paper or other material upon which the impression is desired being
placed upon the impression pad, the handle of the cam lever d, d, is depressed
by hand, which will have the effect of bringing down the slide c, c, and die or
type holder o, o, and pressing the coloring matter out of the endless band
or ribbon will produce a corresponding imprint upon the paper or other
material upon the impression pad. Upon releasing the cam lever d, d, the
spring and levere will raise the slide c, c, and 'die or type holder o, o, into a

page_text: reacting position, and at the same time the pall n, acting upon the ratchet
wheel m, will advance the endless band or ribbon 1, 1, slightly, so as to
present a fresh surface to be acted upon by the die or type at each impression.
Having now described the nature and object of my said "Improvements in
Apparatus for Printing or Endorsing in Colors on Paper or other Surfaces,"
together with the manner of carrying the same into practical effect, I would
remark, in conclusion, that I claim as my Invention, the general construction
and arrangement of endorsing press, as shewn in the Drawings, and herein-
before particularly described; and more especially I claim the use or employ-
ment in such presses of an endless band or ribbon of silk, or other woven or
infrangible material, prepared or saturated with coloring matter, and advanced
by means of a ratchet wheel and pall, so as continually to present a fresh
surface to the action of the die or type.
In witness whereof, I, the said Griffith Jarrett, have hereunto set my
hand and seal, this Twenty-seventh day of November, in the year of
our Lord One thousand eight hundred and fifty-seven.
