Year: 1869

page_text: LETTERS PATENT to Oliver Sarony, Photographer, South Cliffs,
Scarborough, in the County of York, for the Invention of "In-
PROVEMENTS IN PHOTOGRAPHS TO GIVE THEM ARTISTIC EFFECT, AND TO
PRODUCE ENLARGED AND PERMANENT PICTURES FROM SMALL NEGATIVES."
Sealed the 6th August 1869, and dated the 8th February 1869.
PROVISIONAL SPECIFICATION left by the said Oliver Sarony at the
Office of the Commissioners of Patents, with his Petition, on the
8th February 1869.
I, OLIVER SARONY, Photographer, South Oliffs, Scarborough, in the
County of York, do hereby declare the nature of my said Invention for
**IMPROVEMENTS IN PHOTOGRAPHS TO GIVE THE ARTISTIC EFFECT, AND TO
PRODUCE ENLARGED AND PERMANENT PICTURES FROM SMALL NEGATIVES," to be
as follows (that is to say)
I give effect to my Invention in the following way :-I take a small
negative portrait and enlarge the same upon glass, either by sun or
artificial light, which portrait I back up with paper on which has been
lithographed free hand lines.

page_text: This improved process (which I purpose entitling "photo-crayon
vignette" imparts to the picture the effect of the finest sepia drawing.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Oliver Sarony in the Great Seal Patent Office on
the 7th August 1869.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, OLIVER
SARONY, Photographer, South Cliffs, Scarborough, in the County of
York, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Eighth 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 Oliver Sarony, Her special licence
that I, the said. Oliver Sarony, my executors, administrators, and assigns,
or such others as I, the said Oliver Sarony, 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 PHOTOGRAPHS TO
GIVE THEM ARTISTIC EFFECT, AND TO PRODUCE ENLARGED AND PERMANENT PICTURES
FROM SMALL NEGATIVES," upon the condition (amongst others) that I, the
said Oliver Sarony, by an instrument in writing under my hand and seal,
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 Oliver Sarony, 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 (that is to say):-
:-
. I give effect to my Invention in the following way :-I take a small
negative portrait and enlarge the same to any suitable extent or
variation upon glass, either by sun or artificial light, which portrait I

page_text: back up with, by preference, rough drawing paper or other suitable
equivalent material on which has been lithographed hatched shading
or free hand lines or tint, such lining or tinting being so arranged on
the paper backing as to properly surround the transparent picture on
the glass when placed before it.
This improved process or treatment of photographic pictures (which
I purpose entitling "photo-crayon vignette") imparts to the picture
the artistic effect of a highly finished sepia drawing.
But with a view of being well understood I will further detail the
character of my Invention; as for example, I take a small negative
portrait or picture and enlarge the same on glass. by sun or suitable
artificial light as before referred to, but as it is important to the result
that the shadows should be clear I by preference use old collodion
containing bromine and iodine, and sensitize the plate in a bath about
thirty-five to forty grains strong, rendered slightly acid, the time of
immersion being short, as will be well understood by an experienced
practical photographic operator. To develop I prefer to use pyrogallic
acid one grain, citric acid one and a half grains; with sufficient. spirits
of wine to cause it to run freely over the plate, fixing the portrait with
hydro-sulphate of soda. I will here observe that should the negative
appear hard, extra exposure and a plentiful use of developer will tone
and soften the picture.
In enlarging my pictures from small negatives I have found
"Solomon's magnesium enlarging apparatus" to answer well, the
time of exposure being about thirty seconds with an ordinary negative,
but the time may be regulated by the experience of the operator.
The transparent picture or portrait thus produced I place on, by
preference, a rough surfaced paper, well known to artists, on which I
print, by means of lithography, hatched lines or tinted shading or
softening background, the transparent picture being so arranged on
the glass as to fall in a suitable position for the lithographic hatching
or shading to blend into and with the softened outline of the photo-
graphic picture, and the transparent picture on the glass with the
lithographed paper back being united and mounted in the usual way
with a suitable glass and frame for protection completes my improved
process, and renders the same ready for suspension, or other modes or
means for protecting and exhibiting the picture so produced.

page_text: Having thus described and set forth the nature of my improvements,
I wish it understood that the same may be diversified without departing
from the spirit and object of my Invention, as for instance, the hatching
or toning instead of being lithographed on paper may be reprinted on
the same glass containing the transparent picture, and in that case the t
portrait or picture may be backed up with plain paper or otherwise,
which will produce the same effect as before described, nor do I purpose
.confining myself to the colour of the lithographic ink or chalk producing
the hatching, as the same may be of a grey or other colour or colours
as desired; but what I claim as my Invention and wish protected by 1
these my
in part recited Letters Patent is, giving additional artistic
effect to transparent photographic pictures enlarged from small negatives
in the manner herein described and set forth.
In witness whereof, I, the said Oliver Sarony, have hereunto set
my hand and seal, this Fourth day of August, in the year of 1
our Lord One thousand eight hundred and sixty-nine.
OLIVER SARONY. (L.S.)
Witness,
