IMPROVEMENTS IN CYLINDER PRINTING
Year: 1850

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, HENRI
JEREMY CHRISTEN, of Paris, in the Republic of France, Engineer, send greeting,
WHEREAS Her present most Excellent Majesty Queen Victoria, by Her
Royal Letters Patent under the Great Seal of the United Kingdom of Great
Britain and Ireland, bearing date at Westminster, the Nineteenth day of
September, One thousand eight hundred and fifty, in the fourteenth year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto me;
the said Henri Jeremy Christen, my exors, adñors, and assigns, Her especial
license, full power, sole privilege and authority that I, the said Henri Jeremy
Christen, my exors, admors, and assigns, or such others as I, the said Henri
Jeremy Christen, my exors, adiñiors, 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 expressed, should and lawfully might make, use, exercise, and vend,
within England, Wales, and the Town of Berwick-up-Tweed, my Invention of
"IMPROVEMENTS IN CYLINDER PRINTING;" in which said Letters Patent is
contained a proviso, that I, the said Henri Jeremy Christen, shall cause a
particular description of the nature of my said Invention, and in what manner
the same is to be performed, by an instrument in writing, under my hand and
seal, 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
Henri Jeremy Christen, do hereby declare that the nature of my said Invention,

page_text: and the manner of performing the same, are fully described and ascertained in
and by the following description thereof, reference being had to the Drawing
hereunto annexed, and to the figures and letters marked thereon (that is to
say)
The Invention consists of so printing with cylinders having the whole of 5
their surfaces engraved as to leave blank or unprinted spaces on the printed
fabrics according to any shape or design. These improvements will be found
applicable to all description of cylinder printing machinery, and the Invention
consists of placing at the back of the fabric, which it is desired to print, a
design or pattern, hollow and in relief, which will cause parts of the fabric
which is to be printed by the engraved cylinder to be pressed in contact with
the engraved surface of the cylinder, whilst other parts of the fabric, where
the hollows in the pattern are, will not be pressed on, and therefore will not
be printed by the engraved cylinder.
In the Drawing I have shewn the application of my improvements to a
roller machine. D, D, represents an endless fabric which is placed at the back
of the fabric or cloth to be printed, the length of this cloth D may be varied
according to the design, and the width of it will be regulated by the width of
the cloth to be printed. This endless fabric D is made by cementing four or
other suitable number of thicknesses of cotton or other fabric by a suitable
flexible cement, (gutta percha cement is preferred,) and on to this a surface of
woollen fabric is cemented, the pattern of the plain part or the part which is
not to be printed, being produced. by removing or cutting away of parts of the
surface of woollen cloth, by which the fabric which is being printed by the
engrayed cylinder will not be pressed on at those parts, and they therefore will
be left plain; or other suitable materials may be employed which possess
sufficient flexibility.
It is not essential that the pattern D should be endless, it may, when desired
be of the same length as the fabric to be printed, or in place of using a fabric
Da roller or cylinder may be employed where the extent of pattern will admit
of it, hollows being made in the surface thereof where the printing cylinder is
not to print the.cloth or fabric.
The printing is in other respects to be performed in the ordinary manner.
In witness whereof, I, the said Henri Jeremy Christen, have hereunto
set my hand and seal, this Eighteenth day of March, in the year of
our Lord One thousand eight hundred and fifty-one.
HENRI JÉRÉMIE (L.B.) CHRISTEN.
