IMPROVEMENTS IN ORNAMENTING SURFACES
Year: 1869

page_text: LETTERS PATENT to John Macintosh, of North Bank, Regent's Park, in
the County of Middlesex, for the Invention of "IMPROVEMENTS IN
ORNAMENTING SURFACES."
Sealed the 4th May 1869, and dated the 3rd February, 1869.
PROVISIONAL SPECIFICATION left by the said John Macintosh at the
Office of the Commissioners of Patents, with his Petition, on the
3rd February, 1869.
I, JOHN MACINTOSH, of North Bank, Regent's Park, in the County
of Middlesex, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN ORNAMENTING SURFACES," to be as follows:-
My Invention consists in using a combination of paraffin or stearic
acid,-india-rubber, and collodion mixed with metallic powders or gold
or silver leaf for the ornamentation of surfaces, whereby they are
rendered waterproof and not liable to tarnish or oxidation. In some
cases I use the compound of india-rubber and paraffin or stearic acid as
a ground, and spread or lay the metallic powder or leaf thereon, coating
Price d

page_text: the whole with a clear solution of varnish to prevent oxidation. When
it is desired to ornament elastic fabrics a lesser quantity of the paraffin
or stearic acid and collodion is used according to the degree of elasticity
required, the proportion of the different ingredients varying according to
the elasticity or flexibility of the material to be manufactured, the greater
proportion of india-rubber being. used where the flexibility required is the
greatest.
SPECIFICATION in pursuance of the conditions of the Letters Patent
filed by the said John Macintosh in the Great Seal Patent Office
on the 3rd August 1869.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
MACINTOSH, of North Bank, Regent's Park, in the County of Middlesex,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Third day of February, in the year of
our Lord One thousand eight hundred and sixty-nine, in the thirty-
second year of Her reign, did for Herself, Her heirs and successors,
give and grant unto me, the said John Macintosh, Her special licence
that I, the said John Macintosh, my executors, administrators, and
assigns, or such others as I, the said John Macintosh, my executors,
administrators, and 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, exercise, and
vend, within the United Kingdom of Great Britain and Ireland, the
Channel Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN
ORNAMENTING SURFACES," upon the condition (amongst others) that I, the
said John Macintosh, my executors or administrators, by an instrument in
writing under my, or their, or one of their hands and seals, should particu-
larly describe and ascertain the nature of the said Invention, and in what
manuer 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 John Macintosh, do hereby declare
the nature of my said Invention, and in what manner the same is to be
per-

page_text: formed, to be particularly described and ascertained in and by the following
statement:-
My Invention consists in using a combination of paraffin and stearic
acid, india-rubber, and collodion mixed with metallic powders or gold or
silver leaf for the ornamentation of surfaces, whereby they are rendered
waterproof and not liable to tarnish or oxidation. In some cases I use
the compound of india-rubber and paraffin or stearic acid as a ground,
and spread or lay the metallic powder or leaf thereon, coating the whole
with a clear solution of varnish to prevent oxidation. When it is desired
to ornament elastic fabrics a lesser quantity of the paraffin or stearic
acid and collodion is used according to the degree of elasticity required;
the proportions of the different ingredients varying according to the
elasticity or flexibility of the material to be manufactured, the greater
proportion of india-rubber being used where the flexibility required is the
greatest.
The combination first above named is applicable to the ornamentation of
inflexible materials, such as metal, wood, stone, &c. For the ornamenta-
tion of elastic or flexible materials I use the compound containing the larger
proportion of india-rubber. I apply the material, diluted to a proper con-
sistency either by heat or petroleum or other suitable solvents, with a brush
or by other suitable means. The absence of acids in the solvents or varnish is
indispensible.
In witness whereof, I, the said John Macintosh, have hereunto set
my hand and seal, this Third day of August, in the year of our Lord
Une thousand eight hundred and sixty-nine.
JOHN MACINTOSH (L.S.)
