IMPROVEMENTS IN THE PRODUCTION OF PLAIN OR COLOURED PHOTOGRAPHIC AND OTHER PICTURES
Year: 1868

page_text: LETTERS PATENT to John Pouncy, of Dorchester, in the County of
Dorset, for the Invention of "IMPROVEMENTS IN THE PRODUCTION OF
PLAIN OR COLOURED PHOTOGRAPHIC AND OTHER PICTURES."
Sealed the 15th June 1869, and dated the 17th December 1868.
PROVISIONAL SPECIFICATION left by the said John Pouncy at the
Office of the Commissioners of Patents, with his Petition, on the
17th December 1868.
I, JOHN POUNCY, of Dorchester, in the County of Dorset, do hereby
declare the nature of the said Invention for "IMPROVEMENTS IN THE
PRODUCTION OF PLAIN OR COLOURED PHOTOGRAPHIC AND OTHER PICTURES," to be as
follows:-
My Invention consists of an improved method of producing and
colouring photographic or other pictures such as are herein-after
described.
A photographic or other picture is produced in any colouring matter
being carbon, or pigment, or other material mixed and prepared in oil,

page_text: spirit, or water, or in any similar solution, and made sensitive according
to any of the known methods (as well as those described in the Pro-
visional Specification of my application for Letters Patent No. 780,
A.D. 1858, and the Specification of my Patent No. 267, A.D. 1863).
The colors required are laid on over the surface of the several parts &
of the photographic or other picture on the reverse or obverse side
before transferring the same to the canvas or to the surface of any other
material, thus saving much time and labour in colouring, and preserving
the whole of the detail of the photographic or other picture, which has
hitherto been partially obliterated by the application of colours.
Monochrome pictures not required to be transferred are printed on
a transparent material, paper, silk, or other surface, and if intended to
be finished on the same material, the medium of making the said
material transparent is to be removed by means in accordance-with-
the nature of that material and so that the picture may finally appear
on the said material in its original purity. Hence the picture is in
the fibre of and becomes part of the paper or fabric on which it is
produced, which hitherto, has not been accomplished.
Pictures may when required be obtained on gelatine, collodion, mica,
or other transparent material directly on to the transparent surface, and
there left impressed on the same.
Thus by means of my Invention I produce photographs in carbon
or pigments, either in oil, spirit, or water, or similar solution, preserving.
and restoring the original condition of the material on which such
pictures are produced, and I can colour photographs or other pictures
so produced in oil, or spirit, or water colour pigments before transferring
the same.

SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said John Pouncy in the Great Seal Patent Office on
the 17th June 1869.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
POUNCY, of Dorchester, in the County of Dorset, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Seventeenth day of December, in the
3

page_text: year of our Lord One thousand eight hundred and sixty-eight, in the
thirty-second year of Her reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto me, the said John Pouncey, Her special
licence that I, the said John Pouncey, my executors, administrators,
and assigns, or such others as I, the said John Pouncey, 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 niake, 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
THE PRODUCTION OF PLAIN OR COLOURED PHOTOGRAPHIC AND OTHER PICTURES,"
upon the condition (amongst others) that I, the said John Pouncey,
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 imme-
diately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said John Pouncy, do hereby declare
the nature of my said Invention, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the
following statement :-
The first object of my Invention is to produce a picture on the rcverse
or obverse side before transferring the same to canvas or to the surface
of any other material where it is to permanently remain.
The second object of my said Invention is to produce a picture in any
transparent substance or in a substance rendered transparent for the
purpose of producing such picture, such substance to be afterwards
restored to its original character as to opacity, which can be effected
by treating such substances as paper in a solution as bercafter
described, and afterwards washing out the solution as also bereafter
described, whereby a picture can be produced capable of permanent
existence as an incorporation with the texture of the material, in which
the picture is so produced as aforesaid.
Further when and where desirable the picture produced may however
be transferred to any other material, whether transparent or opaque;
both before and after development, that is to say, as to the first object
of my Invention I produce a photographic or other picture by any

page_text: available means in any colouring matter being carbon or pigments, or
other material mixed and prepared in oil, spirit, or water, or in any
similar solution, and made sensitive according to any of the known
methods (as well as those described in the Provisional Specification of
my application for Letters Patent, No. 780, A.D. 1858, and the Spe- 5
cification of my Patent, No. 267, A.D. 1863). The colours required are
laid on over the surface of the several parts of the photographic or
other picture on the reverse or obverse side before transferring the
same to canvas or to the surface of any other material, thus saving
much time and labour in colouring and preserving the whole of the
detail of the photographic or other picture, which has hitherto been
partially obliterated by the application of colours in the manner here-
tofore adopted.
As to the second object of my said Invention, monochrome pictures
not required-to-be-transferred are to be printed on a transparent material,
paper, glass, silk, or other-surface,_and_if_intended to be finished on
the same material the medium of making the said material transparent
is to be applied after the colouring matter and removed by means in
accordance with the nature of that material, and so that the picture
may finally appear on the said material in its original purity. Hence
the picture is in the fibre of and becomes part of the paper-or-fabric
on which it is produced, which hitherto has not been accomplished.
Pictures may when required be obtained on transparent or opaque
material directly on to the transparent or opaque surface, or transferred
to the same and there left impressed on the same or be transferred if
required.
Thus by means of my Invention I produce photographs in carbon or
pigments, either in oil, spirit, or water, or similar solution, preserving
and restoring the original condition of the material on which such
pictures are produced, and I colour photographs or other pictures so
produced in oil, spirit, or water colour pigments before or after trans-
ferring the same.
In order that my Invention may be fully understood I will now state
the details of the method of procedure I prefer to adopt, although I do
not limit myself exactly to such details.
The course I adopt is to first, apply the required monochrome colour
all over the surface of the material on which the picture is to be
produced, and the negative is then to be applied to the prepared or

page_text: non-prepared surface, when the light hardens the colouring matter,
the parts not acted upon by light remaining soluble, and are to be
dissolved off either by spirit or water or both according to the nature
of the preparation of the paper or surface on which the picture is
produced.
The solution to be adopted for giving transparency to the paper or
other material used consists of oil or matter such as oils, wax, and
glycerine, turpentine, naptha, paraffin, and benzole, or anything of like
nature, it not being necessary always to use all these ingredients.
The means for restoring the opacity of the paper and fully developing
the picture is by boiled water, and by finally finishing it by immersing
the same in turpentine, naptha, or benzole or any other solvent for
greasy or oleaginous matters.
Having now particularly ascertained and described the nature of my
said Invention, I hereby declare that I claim, the "Improvements in
the Production of Plain or Coloured Photographic or other Pictures,"
consisting in the methods of production described, and the preparation
and application of the various materials required for such production
of such the above-mentioned oil colour or water colour pigment
pictures.
In witness whercof, I, the said John Pouncy, have hereunto set
my hand and seal, this Fifteenth day of June, in the year of
---Ion One thousand eicht hundred and sixty-nine.
