|No. 12,451.JOHN STULL.Improved Stereoscope-Case.Patented February 27, 1855. (Plates, p. 316.)
The inventor says: I do not claim constructing a stereoscope-case, with a single adjustable flap or supplementary lid within the case, as such invention has been made and used before in daguerreotype cases; but I claim constructing a stereoscopic-case, with the three jointed pieces, E E E, or their equivalents, so applied as to preserve at all times a perfect parallelism between that part of the case containing the lenses and the part which contains the figures, so that a perfect stereoscope is formed of the whole as described, and the two figures, B B, by binocular vision, are apparently formed into a solid figure, the whole being at the same time adapted to fold or close into a small flat case, (resembling the common daguerreotype-case) that may be conveniently carried about the person, if so required, substantially as described. (See engravings.)
STEREOSCOPIC CASE.John Stull, of Philadelphia Pa.: Having thus described the construction and operation of my invention, I proceed to state that I do not claim constructing a stereoscope case, with a single adjustable flap or supplementary lid within the case, as such invention has been made and used before in daguerreotype cases.
