page_text: LETTERS PATENT to Edwin Bliss, of No. 36, Percival Street, Clerkenwell,
in the County of Middlesex, Jeweller, and Henry Lamplough, of No. 113,
Holborn Hill, in the said County of Middlesex, Chemist, for the Inven-
tion of IMPROVED MEANS FOR VIEWING MICROSCOPIC PHOTOGRAPHS AND OTHER
Sealed the 22nd August 1862, and dated the 25th February 1862.
PROVISIONAL SPECIFICATION left by the said Edwin Bliss and Henry
Lamplough at the Office of the Commissioners of Patents, with their
Petition, on the 25th February 1862.
We, EDWIN BLISS, of No. 36, Percival Street, Clerkenwell, in the County
of Middlesex, Jeweller, and HENRY LAMPLOUGHI, of No. 113, Holborn Hill,
in the said County of Middlesex, Chemist, do hereby declare the nature of the
said Invention for "IMPROVED MEANS FOR VIEWING MICROSCOPIC PHOTOGRAPHS AND
OTHER MINUTE OBJECTS," to be as follows:-
Our said Invention consists in having a circular disc of metal or other
suitable material with small sight holes perforated therein at a convenient
distance from the edge, and at a proper space apart, and placing opposite to
each hole the photograph or object to be inspected, and having such disc and
objects enclosed in a case with a microscopic lens fixed therein in the line of

page_text: holes in the disc, and a hole through the other side of the case, directly
opposite the lens, so that by causing the disc to revolve the objects placed on
or connected with the disc may be brought seriatim in front of the lens in
the case, and viewed through it. Of course, if the disc be of clear glass, no
sight holes will be required in it. The disc may be caused to revolve by
means of toothed wheels or other known means.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Edwin Bliss and Henry Lamplough in the Great Seal
Patent Office on the 25th August 1862.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, EDWIN
BLISS, of No. 36, Percival Street, Clerkenwell, in the County of Middlesex,
Jeweller, and HENRY LAMPLOUGH, of No. 113, Holborn Hill, in the said
County of Middlesex, Chemist, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-fifth day of February, in the year of our Lord
One thousand eight hundred and sixty-two, in the twenty-fifth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto us,
the said Edwin Bliss and Henry Lamplough, Her special licence that we, the
said Edwin Bliss and Henry Lamplough, our executors, administrators, and
assigns, or such others as we, the said Edwin Bliss and Henry Lamplough,
our executors, administrators, and assigns, should at any time agree with,
and no others, from time to time and in 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 "IMPROVED MEANS FOR VIEWING
MICROSCOPIC PHOTOGRAPHS AND OTHER MINUTE OBJECTS," upon the condition
(amongst others) that we, the said Edwin Bliss and Henry Lamplough,
our executors or administrators, by an instrument in writing under our,
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 we, the said Edwin Bliss and Henry Lamplough,
do bereby declare the nature of our said Invention, and in what manner

page_text: the same is to be performed, to be particularly described and ascertained..in
and by the following statement, that is to say :-
Our Invention consists in having a circular disc of metal or other suitablo:
material, with small sight holes perforated therein at a convenient distance:
from the edge, and at a proper space apart, and placing opposite to each hole
the photograph or object to be inspected, and having such disc and objects
enclosed in a case with a microscopic lens fixed therein in the line of the holes
in the disc, and a hole through the other side of the case directly opposite the
lens, so that by causing the disc to revolve the objects placed on or connected
with the disc may be brought seriatim in front of the lens in the case, and
viewed through it. Of course, if the disc be of clear class, no sight hole will bo
required in it. The disc may be caused to revolve by means of toothed wheels
or other known means.
The advantages of our Invention are, that in place of using a separate
Stanhope or other lens to each picture or object viewed, one magnifying
power may be employed for a number of such pictures or objects.
Our Invention is represented in detail by the following Drawings:-
Fig. 1 represents a disc, on one side of which the objects to be viewed
(represented by
Fig. 2,) are placed, each object being cut about
one-eighth of an inch square, and being placed in settings, as represented by
way of example in Fig. 3, at the required distance from the edge of the disc,
so as to bring the objects within the centre of the openings, shown in Fig. 1.
Figs. 4 represent the two sides of the case to hold the disc, and which sides
are perforated in the centre or sunk in the centre of the inside for the disc to
revolve in. Near the edge of each side, and at a distance consistent with
arrangement of objects in the inside, are two bizals, marked A and B, placed
opposite to each other, that on the one side (A) being for the reception of the
magnifying power, and that in the other (B) for the admission of light.
The two sides of the case are brought together and secured by a band of
metal, as represented in Figure 5, with a split screw marked C, that will be,
when completed, screwed in the socket of the handle marked D on Fig. 6.
At the outside edge of the disc, and in perfect truth with each object, holes are
made, that will in conjunction with a bolt and spring shewn by the letter E in
Fig. 6 stop each object exactly opposite the eye piece marked F in Fig. 6;
and letter G in the same Fig. 6 is an ornamental boss used to turn the disc
inside, such boss being placed on the side opposite to the eye piece.
Our Invention is applicable to lockets and other articles of ornament and
amusement.

page_text: Having described the nature of our said Invention, and in what manner the
same is or may be performed, we wish it to be understood we do not claim:
any of the parts taken separately; but that what we claim as our Invention is
the combination and arrangements for viewing microscopic photographs, and
other minute objects, as herein-before described.
In witness whereof, we, the said Edwin Bliss and Henry Lamplough,
have hereunto set our hands and seals, this Twenty-fifth day of August,
in the year of our Lord One thousand eight hundred and sixty-two.
EDWIN BLISS.
