IMPROVEMENTS IN OBTAINING PHOTOGRAPHIC IMPRESSIONS OR PICTURES
Year: 1856

page_text: LETTERS PATENT to William Henry Olley, of No. 2, Brabant Court,
Philpot Lane, in the City of London, Wine Merchant, for the Invention
of "IMPROVEMENTS IN OBTAINING PHOTOGRAPHIC IMPRESSIONS OR PICTURES
Sealed the 6th January 1857, and dated the 6th November 1856.
PROVISIONAL SPECIFICATION left by the said William Henry Olley nt
the Office of the Commissioners of Patents, with his Petition, on the
6th November 1856.
I, WILLIAM HENRY OLLEY, of Number 2, Brabant Court, Philpot Lane,
in the City of London, Wine Merchant, do hereby declare the nature of
the said Invention for "IMPROVEMENTS IN OBTAINING PHOTOGRAPHIC IMPRESSIONS
OR PICTURES OF MICROSCOPIC OBJECTS," to be as follows:-
My Invention consists of certain arrangements of apparatus whereby photo-
graphic impressions or pictures of microscopic objects may be obtained by
means of reflected light.
Having removed the metallic cap by which the eye-piece of the microscope
is usually surmounted, I fit or place in a suitable manner the four-sided
reflecting glass prism, known as the camera lucida, or any other suitable
reflector, upon or near to the eye-piece, and so as to be adjustable according
to the wishes of the operator. The tube or body of the instrument having
been brought into a horizontal position, an inverted camera obscura or darkened
box is placed over the said prism or other reflector, such camera obscura or
darkened box being so constructed and arranged as to fit closely to the body

page_text: or tube of the microscope and to exclude extraneous light. The camera
obscura is constructed and arranged in a suitable manner for the reception
of plates or surfaces properly prepared and rendered sensitive to light, by
any of the processes used in the preparation of plates or surfaces employed
for obtaining photographic pictures and impressions. The microscopec prism
.or other reflector and camera obscura having been properly adjusted, tho
object of which an impression or picture is desired to be obtained is placed
at a proper focus before the object glass of the microscope, when an image
of such object will be formed by reflection from the prism or other reflector
upon the prepared plate or surface previously introduced into the camera.
The prepared plate or surface having been thus exposed to the action of the
light for a suitable length of time, may then be removed from the camera,
and subjected to the other processes used in photographic operations for
developing and fixing the image or picture so obtained and for completing
the effect thereof.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said William Henry Olloy in the Great Seal Patent Office on
tho 6th May 1857.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
HENRY OLLEY, of Number 2, Brabant Court, Philpot Lane, in the City of
London, Wine Merchant, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Sixth 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
William Henry Olley, Her special licence that I, the said William Henry
Olley, my executors, administrators, and assigns, or such others as I, the
said William Henry Olley, 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 of "IMPROVEMENTS
IN OBTAINING PHOTOGRAPHIC IMPRESSIONS OR PICTURES OF MICROSCOPIC OBJECTS,"
upon the condition (amongst others) that I, the said William Henry Olley,
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 Juvention, and in what manner the same was to be

page_text: 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 William Henry Olley, do hereby
declare the nature of my said Invention, and in what manner the samo is to
bo performed, to be particularly described and ascertained in and by the
following statement, that is to say:-
My Invention consists of certain arrangements and combinations of apparatus
whereby photographic impressions of microscopic objects may be obtained.. by
means of reflected light, and which I carry into effect by the combined use
of the microscope, the camera lucida, or other suitable reflector or reflectors,
and the camera obscura, the apparatus being constructed and. arranged as
herein-after described.
Having removed the metallic cap by which the eye-piece of the microscope
is usually surmounted, I fit or place the four-sided reflecting glass prism,
known as the camera lucida, or any other suitable and analogous reflector
or reflectors, upon or near the eye-piece, placing and arranging the same in
a suitable manner for producing an image or images of the object or objects
of which an impression or picture is desired to be obtained, and so as to be
readily adjustable according to the wishes of the operator. The tube or body
of the instrument having been brought into a horizontal position, an inverted
camera obscura or darkened box is placed over the said prism or other
reflector or reflectors, such camera obscura or darkened box being so con-
structed and arranged as to fit closely to the body or tube of the microscope,
and so as to exclude extraneous light. The camera obscura should be
constructed and arranged in a suitable manner, and in accordance with the
methods and principles well understood by persons conversant with the use of
that instrument, for the reception of plates or surfaces properly prepared and
rendered sensitive to light by any of the processes used in the preparation of
plates or surfaces employed for obtaining photographic pictures or impressions.
The microscope, prism, or other reflector or reflectors, and camera obscura,
having been properly adjusted, the object or objects of which an impression
or picture is desired to be obtained should be placed at a proper focus before
the object glass of the microscope, when an image of such object or objects
will be formed by reflection from the prism or other reflector or reflectors
upon the prepared plate or surface, or plates or surfaces, previously introduced
into the camera. The prepared plate or surface, or plates or surfaces, having
been thus exposed to the action of the light for a suitable length of time,
may then be removed from the camera, and subjected to the other processes

page_text: used in photographic operations for developing and fixing the image or picture
or images or pictures so obtained, and for completing the effect thereof, and
which as they are understood by persons conversant with photography and
photographic processes, and form no part of my Invention, it is unnecessary
to describe in this Specification.
I have also abstained from describing the mechanical contrivances by
means of which the several parts of the said apparatus may be moved, adjusted,
and regulated, inasmuch as such mechanical contrivances and arrangements
are already well known, and the construction thereof well understood, and
constitute no part of my Invention.
Having now described and particularly ascertained the nature of my said
Invention, and the manner in which it is to be used and carried into effect,
I would observe, in conclusion, that I do not confine myself to the precise
details or arrangements which I have described or referred to, inasmuch as
variations may be made therefrom, and analogous arrangements or combinations
made without deviating or departing from the principles or main features of
the said Invention; and I wish it to be distinctly understood that what I
consider to be novel and original, and therefore claim as the Invention secured
to me by the berein-before in part recited Letters Patent, is, the arrangement
and combination of apparatus herein-before mentioned and described, or any
variation therefrom by the use of analogous or equivalent arrangements or
combinations, for effecting the purposes berein-before particularly mentioned.
In witness whereof, I, the said William Henry Olley, have hereunto
set my hand and seal, this Fifth day of May, in the year of our Lord
One thousand eight hundred and fifty-seven.

B. S. SANDELL,
Clerk to Mr. E. P. H. Vaughan,.
