To accomplish this result, the photograph isplaced underthe roller H of the pivot leg it) in I V such a position that the center point will coincidewith the needle-point l8 when-it i'sreleased to its full downward position; The roller H will allow the photograph to be'r'otated'around the needle-point l8, so that the photograph and the lever i can then be adjusted to bring the needlemeans for supporting said base on a plane surface, a pointed element attached to said base,-a
