page_text: JOHN HANCOCK jr. 11 Eldon Place, Newcastle on Tyne, Artist, do hereby declare
the nature of my invention for BINOCULAR CAMERA and in what manner the saine
is to be performed, to be particularly described and ascertained in and by the
following statement :-
Namely that the nature of my invention is, that it is a means whereby the two
up side down pictures of nature (the right eye picture and the left eye picture) as
shewn at the three lines lettered E in plan, are thrown together into one right side
up picture in relief (the same as the picture you see when looking through a
stereoscope) as shewn at the two lines lettered F in plan (see plan shewing features
of novelty constituting my Invention) and that the manner in which this is to be
performed is as follows,
Place portion of camera lettered A in plan, having right eye lens lettered H in
plan and left eye lens lettered G in plan, also having inside partition lettered D
in plan. Focus this portion of camera on its ground glass represented by the three
lines lettered E in plan.
You have two up side down pictures, a right eye one, and a left eye one.
Having obtained the focus remove the ground glass and in its place substitute
two sheets of clear glass placed close together side by side as represented in plan
by the three lines lettered E (shewn at large in sketch on plan lettered E*).
Now place portion of camera lettered O in plan, having inside partition
lettered M.
Now place portion of camera lettered B in plan having no inside partition and
having right eye and left eye lenses as in plan (lettered respectively V and K)
So that right eye picture is received on right eye lens and left eye picture on
left eye lens as in plan.
Focus portion of camera lettered B in plan on its ground glass represented by
the two lines lettered F in plan.
You have now one right side up picture in relief (the same as the picture you
see when looking through a stereoscope).
"
Place sensitive plate and obtain the photograph.
Having now particularly described and ascertained the nature of my said
Invention, and in what manner the same is to be performed, I declare that what
I claim is:
"
1. The substituting of two sheets of clear glass instead of ground glass shewn
by the three lines lettered E in plan, and shewn at large in sketch on plan
lettered E* (see plan shewing features of novelty constituting my Invention).
2. The continuation of that portion of camera (having inside partition) drawn
& shaded and lettered C in plan (see plan shewing features of novelty constituting
my Invention).

page_text: 3. The application of that portion of camera having right eye & left eye lenses
and having no inside partition as shewn in plan by the portion of camera drawn
& shaded and lettered B (see plan shewing features of novelty constituting my
Invention).
And that it is the united application of these portions of camera (shewn in plan
by being drawn & shaded and lettered B, C, & E.) with that part of camera
(shewn in plan by being dotted and lettered A) that constitutes the novelty of my
Invention.
