IMPROVEMENTS IN STEREOSCOPIC PICTURES
Year: 1856

page_text: LETTERS PATENT to Richard Harmer, of 12, Princes Street, Spitalfields,.
in the County of Middlesex, Clerk, for the Invention of "IMPROVEMENTS
IN STEREOSCOPIC PICTURES."
Sealed the 29th May 1857, and dated the 29th November 1856.
PROVISIONAL SPECIFICATION left by the said Richard Harmer at the
Office of the Commissioners of Patents, with his Petition, on the 29th
November 1856.
I, RICHARD HARMER, of 12, Princes Street, Spitalfields, in the County of
Middlesex, Clerk, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN STEREOSCOPIC PICTURES," to be as follows:-
My Invention relates to colouring stereoscopic pictures, that is, pictures to
be viewed in the stereoscope produced by the camera or any other means,
the same being printed on paper chemically prepared, by the agency of light
or otherwise, as usual.
In pictures viewed in the stereoscope two similar pictures are introduced
to produce one view, which two pictures heretofore have been exactly similar
in every particular in color and outline, or as nearly so as may be, whereas
according to my Invention I produce and use two pictures in the ordinary
way, similar in outline but different in colour. For example, one picture may

page_text: be colored emerald green and carmine, and the corresponding picture used
therewith may be coloured blue and violet, which colours, when viewed in the
stereoscope, blend with each other, and greatly enhance the effect.
Any other colours may be used, and if selected and used with judgment
produco beautiful effects in such pictures.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Richard Harmer in the Great Seal Patent Office on the
29th May 1857.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, RICHARD
HARMER, of 12, Princes Street, Spitalfields, in the County of Middlesex,
Clerk, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-ninth day of November, in the year of our
Lord One thousand eight hundred and fifty-six, in the twentieth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said Richard Harmer, Her special licence that I, the said Richard Harmer,
my executors, administrators, and assigns, or such others as I, the said Richard
Harmer, 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
STEREOSCOPIC PICTURES," upon the condition (amongst others) that I, the said
Richard Harmer, my executors or administrators, by an instrument in writing
under my, or their, or one of their hands and seals, should particularly
describe and ascertain the nature of the said Invention, and in what manner
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 Richard Harmer, do hereby declare the
nature of my said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following.
statement, reference being had to the Sheet of Drawings hereunto annexed,
and to the figures marked thereon (that is to say):-
:-
My Invention relates to colouring stereoscopic pictures, that is, pictures to
be viewed in the stereoscope produced by the camera or any other means, the

page_text: same being printed on paper chemically prepared by the agency of light or
otherwise, as usual.
In pictures viewed in the stereoscope two similar pictures are introduced to
produce one view, which two pictures heretofore have been exactly similar in
every particular in colour and outline, or as nearly so as may be, whereas
according to my Invention, I produce and use two pictures in the ordinary
way, similar in outline but different in colour. For example, one picture may
be coloured emerald green and carmine, and the corresponding picture used
therewith may be coloured blue and violet, which colours when viewed in the
stereoscope blend with each other, and greatly enhance the effect produced.
Any other colours may be used, and if selected and used with judgment
produce beautiful effects in such pictures.
Fig. 1 represents a collection of shells arranged as a stereoscopic picture
according to my Invention, showing the different colours used to colour
the same shells in the pair of pictures used to produce oue view in the
stereoscope.
Fig. 2 represents shells and other subjects similarly treated, according to
my Invention, which also applies to almost all subjects forming the groups,
figures, or views for stereoscopic pictures, and will be readily understood from
the annexed examples. I apply the colours by hand.
Having described the nature of my Invention, and the manner of carrying
the same into effect, I wish it to be understood that what I claim as of my
Invention, and desire to protect by the heroin-before in part recited Letters
Patent, is, colouring the same parts of the subject forming stereoscopic pictures
of different colours in the two representations or views used for such pictures,
as herein-before described, and represented in the Drawings annexed.
In witness whereof, I, the said Richard Harmer, have hereunto set my
hand and seal, this Twenty-eighth day of May, in the year of our Lord
One thousand eight hundred and fifty-seven.
