Year: 1874

page_text: LETTERS PATENT to John Scudamore Sellon, of Hatton Garden, and
Robert Pinkney, of Bread Street Hill, both in the City of London,
for the Invention of "IMPROVEMENTS IN DYEING AND PRINTING, AND IN
IMPROVED COMPOUNDS FOR SUCH PURPOSES."
Sealed the 12th March 1875, and dated the 24th December 1874.
PROVISIONAL SPECIFICATION left by the said John Scudamore Sellon
and Robert Pinkney at the Office of the Commissioners of Patents,
with their Petition, on the 24th December 1874.
WC, JOHN SCUDAMORE SELLON, of Hatton Garden, and ROBERT
PINKNEY, of Bread Street Hill, both in the City of London, do hereby
declare the nature of our said Invention for "IMPROVEMENTS IN DYEING
AND PRINTING, AND IN IMPROVED COMPOUNDS FOR SUCH PURPOSES," to be as
follows:-
This Invention relates to improvements in dyeing and printing, and
consists in the employment of compounds of vanadium and of soluble
salts or compounds of vanadium for the purposes of dyeing and printing

page_text: in conjunction with other dyeing and printing agents, such, for example,
as the organic, vegetable, animal, or artificially produced dyeing or
printing materials.
In carrying out this Invention the salts or compounds of vanadium
are mixed with the dyeing and printing materials, and in such quantity 5
as shall produce the desired result, so that thic color produced when the
material to be dyed or printed shall be preserved and intensified, and
that the dyeing or printing materials employed shall be economised.
SPECIFICATION in pursuance of the conditions of the Letters Patent
filed by the said John Scudamore Sellon and Robert Pinkney in
the Great Seal Patent Office on the 24th June 1875.
"
TO ALL TO WHOM THESE PRESENTS SHALL COME, wc, JOHN
SCUDAMORE SELLON, of Hatton Garden, and ROBERT PINKNEY, of Bread
Street Hill, both in the City of London, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-fourth day of December, in the
year of our Lord One thousand eight hundred and seventy-four, in' the
38th year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto us, the 'said John Scudamore Sellon and Robert
Pinkney, Her special license that we, the said John Scudamore Sellon
and Robert Pinkney, our executors, administrators, and assigns, or such
others as we, the said John Scudamore Sellon and Robert Pinkney,
our executors, administrators, or assigns, should at any time agree with
and no others, from time to time and at all times thereafter during the
term therein expressed, should and lawfully might make, use, exercisec,
and vend, within the United Kingdom of Great Britain and Ireland,
the Channel Islands, and Isle of Man, an Invention for "IMPROVEMENTS
IN DYEING AND PRINTING," upon the condition (amongst others) that wc,
the said John Scudamore Sellon and Robert Pinkney, our exccutors or
administrators, by an instrument in writing under our hands and seals,
or under the hand and scal of one of us, should particularly describe
and ascertain the nature of the said Invention, and in what manner tho
same was to bo performed, and cause the same to be filed in the Great

page_text: Seal Patent Office within six calendar months next and immediately
after the date of the said Letters Patent.
NOW KNOW YE, that we, the said John Scudamore Sellon and
Robert Pinkney, do hereby declare the nature of our 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:―
This Invention relates to improvements in dyeing and printing, and
consists in the employment of compounds of vanadium and of soluble
salts or compounds of vanadium for the purposes of dyoing and printing
in conjunction with other dyeing and printing agents, such, for example,
as the organic, vegetable, animal, or artificially produced dyeing or
printing materials as are now employed.
In carrying out our Invention we employ the dyes or coloring matters
in the ordinary manner, and we add to the dye baths the salts or com-
pounds of vanadium herein-after referred to, and effect the dyeing of the
fabrics or goods in the ordinary manner, as is well understood.
When applying our Invention to the printing of fabrics the salts or
compounds of vanadium are to be mixed with the coloring matters or
compounds employed for that purpose, and the printing of the fabrics is
then effected in the usual manner.
What we wish to be understood as the organic, vegetable, and animal
coloring matters or artificially produced dyeing or printing materials
which are capable of being employed in conjunction with the salts or
› compounds of vanadium are such as may be classified under the following
types, namely:-

page_text: materials specificed good results may be obtained, and which may bo
taken as types of the series of coloring matters to which our Invention
is applicable.
In the employment of our Invention in conjunction with artificial
alizarino or in conjunction with madder, logwood, or cochincal, we havo
found that the salts or compounds of vanadium herein referred to may be
advantageously employed in about the following proportions, vidclicit,
from about twenty to about two hundred grains of say, for example, the
chloride of vanadium or of the other salts or compounds of vanadium to
one gallon of the dye solutions of the strength now usually employed for
producing the various colors and tints desired.
The salts or compounds of vanadium which we have found applicable
for the purposes of our Invention are the soluble salts, such, for example,
as tho chlorides of vanadium or the soluble vanadiates, but other com-
pounds may be employed.
Having now described and particularly ascertained the nature of the
said Invention, and the manner in which the same is or may be used or
carried into effect, we would observe in conclusion that we are aware
that salts and compounds of vanadium have been employed in con-
junction with aniline and with oxidizing agents, such, for example, as
chlorate of potash, we do not therefore lay any claim to such employ-
ment of the salts or compounds of vanadium, but what we do claim as
our Invention is, the employment and use of the salts or compounds of
vanadium in conjunction with organic, vegetable, animal, or artificially
prepared dyeing and printing materials.
In witness whereof, I, the said Robert Pinkney, on behalf of John
Scudamore Sellon and myself, have to this our Specification set
my hand and scal, the Twenty-third day of June, One thousand
cight hundred and-seventy-five.
