EDOUARD LORADOUX BELLFORD, of 16, Castle Street, Holborn, in the County
of Middlesex, Patent Agent, 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 Twenty-sixth
day of August, in the fifteenth year of Her reign, did, for Herself, Her heirs
and successors, give and grant unto me, the said Auguste Edouard Loradoux
Bellford, my exors, adññiors, and assigns, Her especial licence, full power, sole
privilege and authority, that I, the said Auguste Edouard Loradoux Bellford,
my exors, adiñors, and assigns, or such others as I, the said Auguste Edouard
Loradoux Bellford, my exors, adiñors, and 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-upon-Tweed, and,
in the Islands of Guernsey, Jersey, Alderney, Sark, and Man, and also in all
Her said Majesty's Colonies and Plantations abroad, the Invention com-
municated to me, by a foreigner residing abroad, of "IMPROVEMENTS IN THE
MACHINERY AND APPARATUS FOR PRINTING FABRICS AND OTHER SURFACES;" in
which said Letters Patent there is contained a proviso, that I, the said
Auguste Edouard Loradoux Bellford, shall cause a particular description of
the nature of the said Invention, and in what manner the same is to be

page_text: performed, by an instrument in writing under my hand and seal, to be enrolled
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
Auguste Edouard Loradoux Bellford, do hereby declare that the nature of
the said Invention, and the manner in which the same is to be performed,
are particularly described in and by the following statement thereof, that is
to say:-
The Invention consists principally in the application of sieves, suitably con-
structed for the purpose of distributing on cloths, papers, stuffs, leather, and
all textile fabrics, and, in general, on all substances that are susceptible of
being dyed or printed, colours, mordants, and rongeants (the latter is a term
by which the Inventor calls the various acids, spirits, or alkalies, or other
matters or liquids which are used by dyers to eat away colours or to substitute
one colour for another). By this method the material dyed may be speckled
or spotted with a variety of colours at a greater saving of time or trouble than
by the means hitherto employed. The best arrangement for obtaining great
uniformity in the operation of distributing the colour, mordants, or rongeants,
is to have four sieves superposed one over the other, and over these sieves to
have a perforated cylinder so arranged as to have a regular to-and-fro motion
over the top of the sieves. In this cylinder the matter to be distributed is
placed and falls through the sieves in spots or specks of dimensions pro.
portionate to the degree of fineness of the sieves. The colour or colours may
be laid on a material white or already dyed of a uniform colour, and previously
soaked with a mordant suitable for the colour to be applied; or a mordant may
be distributed through the sieves on to the material, and the whole of the
material afterwards may be dipped into the colour with which it is desired to
speckle it; then it must be washed, and this colour will be found to have only
adhered to the spots where the mordant was dropped; or, if it be desired to.
obtain white spots on a plain coloured material, or rongeant made to fall
through the sieves on to the material will eat away the colour at the places
where it falls, and thus produce white spots. Some rongeants, instead of
eating away the colour, merely change it to another; this may act in a similar
manner, and spots or specks of a different hue may be obtained. If the
substance to be coloured be paper, the colour is distributed in the same
manner as for cloths, but the colour must then contain a fixing principle, or the
paper, and then the paper must be damped or a pressing roller used, in order.
