Year: 1858

page_text: LETTERS PATENT to Adolphe Paul Auguste Beau, of 152, Regent Street,
London, for the Invention of "A POCKET STEREOSCOPE."
Sealed the 21st April 1859, and dated the 27th October 1858.
PROVISIONAL SPECIFICATION left by the said Adolphe Paul Auguste
Beau at the Office of the Commissioners of Patents, with his Petition,
on the 27th October 1858.
I, ADOLPHE PAUL AUGUSTE BEAU, of 152, Regent Street, London, do hereby
declare the nature of the said Invention for "A POCKET STEREOSCOPE," to be
as follows:-
The object of the Invention is to form a stereoscope in such a way and of
such a shape that it may be carried easily in the pocket and used as a pocket
book. To effect this, I bind or fix the frame in which the two lenses are
placed between two covers or flaps, within the said covers I fix pockets,
writing material, &c.
A moveable division may, if necessary, be placed between the two lenses;
the whole may be held together when the covers are closed by two clasps or
by an elastic or other fastening.
Instead of the covers I can simply make use of a sheath in which the
frame will slide, using the sheath as a holder when the instrument is to be
used.

TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ADOLPHE
PAUL AUGUSTE BEAU, of 152, Regent Street, London, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-seventh day of October, in the year of our
Lord One thousand eight hundred and fifty-eight, in the twenty-second year
of Her reign, did, for Herself, Her heirs and successors, give and grant
unto me, the said Adolphe Paul Auguste Beau, Her special licence that
I, the said Adolphe Paul Auguste Beau, my executors, administrators, and
assigns, or such others as I, the said Adolphe Paul Auguste Beau, 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 "A POCKET STEREOSCOPE," upon the condition
(amongst others) that I, the said Adolphe Paul Auguste Beau, 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 Adolphe Paul Auguste Beau, 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 :-
My Invention consists in forming stereoscopes in such a way and of such a
bulk or size that they may easily be carried in the pocket; I propose to effect
this by binding or attaching the frame in which the two lenses are set to two
covers or flaps, so as to resemble a small pocket book or note book. These
flaps or covers are made so as to have pockets in the inside, within which may
be carried writing material, visiting cards, postage stamps, railway tickets and
such like articles, and in some cases even the stereoscopic views. When in
use a moveable diaphragm let into a groove in the lense frame, projects out
at right angles from it, so as to separate the field of view of each lense; by
means of a sheath, within which it slides, this diaphragm may be lengthened

appended.
In witness whereof, I, the said Adolphe Paul Auguste Beau, have
hereunto set my hand and seal, this Twenty-sixth day of April, in the
year of our Lord One thousand eight hundred and fifty-nine.
Witness,
ADOLPHE PAUL AUGUSTE BEAU. (L.S.)
