Year: 1845

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
MCINTOSH, of Glasgow, Gentleman, send greeting.
WHEREAS Her present most Excellent Majesty Queen Victoria, by Her
Royal Letters Patent under the Great Seal of Great Britain, bearing date at.
Westminster, the Eighth day of May, in the eighth year of Her reign, did,
for Herself, Her heirs and successors, give and grant unto me, the said John
McIntosh, my exors, adiñors, and assigns, Her especial licence, full power,
sole privilege and authority, that I, the said John McIntosh, my exors, admors,
and assigns, or such others as I, the said John McIntosh, my exors, admors,
or assigns, should at any time agree with, and no others, from time to time
and at all times during the term of years therein mentioned, should and
lawfully might make, use, exercise, and vend, within England, Wales, and
the Town of Berwick-upon-Tweed, my Invention of "IMPROVEMENTS IN PRE-
PARING MATERIALS FOR COLORING AND PRINTING CALICOES AND OTHER FABRICS,
AND IMPROVEMENTS IN PRINTING AND ORNAMENTING FABRICS;" in which said
Letters Patent is contained a proviso that I, the said John McIntosh, shall
cause a particular description of the nature of my said Invention, and in what
manner the same is to be performed, to be inrolled in Her said Majesty's High
Court of Chancery within six calendar months next and immediately after.
the date of the said in part recited Letters Patent, as in and by the same,
reference being thereunto had, will more fully and at large appear.
NOW KNOW YE, that in compliance with the said proviso, I, the said
John MoIntosh, do hereby declare that the nature of my said Invention, and

page_text: that is to say-
My Invention consists,-
First, in combining flock and a solution of india rubber, or a solution of
gutta percha, and using the same as a printing material for calico and other
fabrics.
Secondly, my Invention consists of improvements in the machinery or appa-
ratus used in printing or ornamenting calico and other fabrics. And,
Thirdly, my Invention consists of improvements in apparatus for spreading
color on to a sieve cloth for block printing.
And in order that my Invention may be most fully understood and readily
carried into effect, I will proceed to describe the means pursued by me.
The object of the first part of my Invention is to print flock of different
colors in patterns on to calico, paper, or other fabrics, by mixing flock with a
clear solution of india rubber, or by mixing flock with a clear solution of gutta
percha, so as to be of a consistence similar to the colors used in engraved
roller or engraved plate printing; and such preparation of flock is to be used
in the same manner as if it were color, by means of engraved rollers or plates.
By this means I am enabled to produce very beautiful effects in printing calico
and other fabrics, the preparations of flock being made with flock of different
colors, which, being used in machines capable of printing with several colors,
various colored flocks may be brought into the same pattern, and owing to the
solution used being of india rubber or of gutta percha, the flock will adhere
securely to the fabric. The solution of india rubber and of gutta percha we
prefer is that made with naptha; and in order that the solution of india rubber.
may be clear, I use the whitest india rubber I can obtain; but I make no
claim to the solutions when not combined with flock, and the flock is obtained
of the colors desired before mixing them with the solution.
The second part of my Invention consists of applying a roller coated with
india rubber to engraved rollers or plates, for the purpose of keeping the
engraving clean. It is well known that in printing from engravings on rollers
or plates, that the engraving requires from time to time to be washed out, in
order that the parts more or less coated with color drying thereon may be
cleansed. I have discovered that if a roller coated with india rubber be con-
stantly pressing against an engraved roller or cylinder used in printing, that
owing to the peculiar property possessed by this substance, that the pressing of
the india rubber into the engraving will cause the coloring matters in the

page_text: engraving, and which would adhere thereto and tend to stop up particularly
the finer parts, to be removed; and such is the case if a similar roller is applied
to an engraved plate, by passing it to and fro a like effect would be obtained.
In applying a roller so coated, I apply it in any convenient position, so as to
be pressed in contact and revolve with the engraved roller.
The third part of my Invention consists of apparatus for spreading the color
on a suitable sieve cloth or felt for block printing.
Figure 1 shews a side section; Figure 2, and end section; and Figure 3,
a plan of the apparatus. a, a, is a bag to contain the water suitably thickened,
as heretofore, in making sieves for block printing, but I prefer that it should
be made into the form of a bag, of waterproof fabric. b, b, is the framing-
which supports the sieve. d is felt spread evenly over the sieve, and the felt is
fastened at its edges to the frame. e is a trough, and f, f, are brushes; and it
is the use of a trough to contain the color moving over the surface of the felt or
sieve cloth with brushes which constitutes the peculiar character of novelty of
this apparatus, in place of using a brush simply to spread the color. The
trough is so formed as to press on the sieve cloth, the trough being open below;
hence, as the trough is moved a quantity of color is spread on to the sieve
cloth, and the same is acted on by the brushes, so that the color will be evenly
spread for the block. I would remark, that I prefer the arrangement shewn,
but do not confine myself thereto, as the shape of the trough and arrangement of
brushes may be varied so long as the trough or color holder open at bottom is
used, capable of moving over the sieve cloth, and thus depositing color thereon,
the same being further spread by brushes.
Having thus described the nature of my Invention, and the manner in
which the same is to be performed, I would have it understood that what I
claim is,―
First, the using flock combined with a solution of india rubber or of gutta
percha as a printing material.
Secondly, I claim the mode of cleansing engraved printing rollers or plates
with a roller or surface of india rubber. And,
Thirdly, I claim the application and spreading of color from a trough or
vessel open at bottom on to a sieve cloth, and further spreading it by brushes,
as above described:
In witness whereof, I, the said John McIntosh, have hereunto set my
hand and seal, this Eighth day of November, in the year of our
Lord One thousand eight hundred and forty-five.
JOHN (L.S.) MACINTOSH.
