Year: 1866

page_text: LETTERS PATENT to Auguste Fournet and Octave Nadaud, of 29, Tich-
borne Street, Piccadilly, London, in the County of Middlesex, for the
Invention of "A MAGIC CAMERA."
Sealed the 22nd March 1867, and dated the 27th November 1866.
PROVISIONAL SPECIFICATION left by the said Auguste Fournet and
Octave Nadaud at the Office of the Commissioners of Patents, with their
Petition, on the 27th November 1866.
We, AUGUSTE FOURNET and OCTAVE NADAUD, of 29, Tichborne Street,
Piccadilly, London, in the County of Middlesex, do hereby declare the nature
of the said Invention for "A MAGIC CAMERA," to be as follows:-
1°. Its principal objects are to supersed all the optical instruments of the
same apparent kind, inasmuch as it does not require any previous knowledge
of optical science, and save all the long preparations indispensables to all
others instruments in use till now.
2º. To enable any persons or children to show a picture on a ground glass
at a fixed focus, either by daylight or at night, magnifying the original picture
from four to twenty times, and above.
30. All the transparent pictures used for all others instruments with a
magnifying power may be adapted to our magic camera, to say, transparent.
pictures on glasses, photographic positives, &. &*.

page_text: DESCRIPTION AND CONSTRUCTION OF THE MAGIC CAMERA.
Our magic camera is composed of two different parts. The first part is a
globe or sphere made of brass, tin, wood, or any other material bored at the
top and bottom to allow a lamp, candle, or any other kind of light to be
put inside and pass through it; the bottom part of the globe or sphere is
to rest on the socket of the lamp, candlestick, or any other kind of lighting
apparatus. In the center of the globe is a round hole, after which is a
groove, in which the picture is placed, and adapted to the groove is a tube,
inside of which are fixed two lenses of a magnifying power from four to
twenty times, or more.
The second part is a camera, equally made of brass, tin, wood, or any other
material, whose communication whith the globe is established by a tube
adapted to its center at the back, in which the globe's tube is inserted. The
face or front of the camera is closed by a ground glass of the size of the apper-
ture, on which when a light is introduced in the globe passing through the
lenses the picture appear magnified according to the lenses' power. The
shape of the globe and camera may vary according to the Inventors's con-
venience as well as the size; the shape may be square, round, octogone, or all
others, and the size the one the Inventors may think to give to it.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Auguste Fournet and Octave Nadaud in the Great Seal Patent
Office on the 24th May 1867.
. TO ALL TO WHOM THESE PRESENTS SHALL COME, 'we, AUGUSTE
FOURNET and OCTAVE NADAUD, of 29, Tichborne Street, Piccadilly, London, in
the County of Middlesex, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-seventh day of November, in the year of our
Lord One thousand eight hundred and sixty-six, in the thirtieth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto us,
the said Auguste Fournet and Octave Nadaud, Her special license that we, the
said. Auguste Fournet and Octave Nadaud, our executors, administrators, and
assigns, or such others as we, the said Auguste Fournet and Octave Nadaud, our
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

page_text: the United Kingdom of Great Britain and Ireland, the Channel Islands, and
Isle of Man, an Invention for "A MAGIC CAMERA," upon the condition (amongst
others) that we, the said Auguste Fournet and Octave Nadaud, our executors
or administrators, by an instrument in writing under our or their bands and seals,
or under the hand and seal of one of us or them, should particularly describé
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 we, the said Auguste Fournet and Octave Nadaud,
do hereby declare the nature of the said Invention, and in what manner the
same is to be performed, to be particularly described and ascertained in
and by the following statement thereof, that is to say :-
The object of this Invention is to construct a magic camera to show on a
ground glass a magnified image of a picture. The camera is composed of two
parts, the first part is a globe or sphere made of brass, tin, wood, or any other
material with an opening through the top and bottom to allow of a lamp,
candle, or.other kind of light being put inside the globe, the bottom of the
globe being by preference arranged to rest on the socket of the lamp or other
kind of lighting apparatus employed. Through the side of the globe a round
hole is formed, in front of which is a slide in which the picture is placed, and
adapted to the slide is a tube, inside of which are two lenses of a magnifying
power of from four to twenty times, or more.
The second part is a camera equally made of brass, tin, wood, or other
suitable material; the back end of this camera is connected with the globe by
a tube into which the tube projecting from the globe is inserted. The face
or front of the camera is closed by a ground glass, on to which (when a light
is introduced into the globe) is thrown a magnified image of the picture
placed in the slide. The shape and size of the globe and camera may be
considerably varied. Any transparent picture, such as the slides now used
with magic lanterns or photographic images on glass or others, may be used
with this magic camera.
And in order that our Invention may be fully understood and readily
carried into effect, we have shown in the Drawings hereunto annexed a magic
camera constructed in the manner we prefer for carrying out our Invention.
DESCRIPTION OF THE DRAWINGS.

page_text: a is the globe made by preference of thin sheet metal for containing the
lamp or other lighting apparatus employed; b is the tube adapted to an
opening in its side; across this tube is formed a slidé composed of two flat
plates c, c¹, between which is placed the picture to be magnified, the picture
being pushed in between them from one side; the slide or frame carrying the
picture is not shown in the Drawing. The front plate c¹ is moveable, and
is pressed towards the fixed plate c by two bent springs d, as shown, so that
the picture is held up against the plate c. An opening is formed through
the centre of both plates to allow the light from the lamp to pass through the
picture. e, e', are the two lenses carried by the tube b; the glass e is fixed in
the rear end of the tube so as to be behind the picture, and the glass e¹ is in
front of the picture, and is carried by an inner tube capable of sliding
within the front end of the tube b; a bent wire handle is fitted to the tube e²,
by which it can be slid backwards or forwards to adjust the focus of the
glasses; the tube also carries a "stop" es, as shown; f is the camera of
thin sheet metal with a tube f¹ at its rear end, into which the front end of the
tube 6 is inserted; the front of the camera is closed by the screen of ground
glass g, on to which, the magnified image of the picture placed in the slide is
thrown when a light is placed within the globe.
In witness whereof, we, the said Auguste Fournet and Octave Nadaud,
have hereunto set our hands and seals, this Second day of March, in
the year of our Lord One thousand eight hundred and sixty-seven.
