Abstract

596,590. Stereoscopic apparatus. FRANKLIN, A. P. Dec. 13, 1945, No. 480. [Class 97 (i)] Optical superposition of stereoscopic images projected side by side, e.g. cinematograph or television images is effected by a viewing device comprising two lens systems comprising front and rear lenses supported on carriers connected by bellows and movable to a collapsed position by a cord system operated by relative movement of an arm supporting the device and a tubular support slidably engaging the arm. The optical axes of the two systems are angularly adjustable in their common plane. As shown, the lenses 1 in holder 6 are supported by lazy tongs 23 from the mounts of lenses 2, a hinge 27. secured at 28 to one mount and pivoted to the other permitting angular adjustment of the optical axes. The device may be collapsed by cords 34, 36 and is carried on an arm 31 telescoping into a support 33 when not in use, the collapsed device being then housed in a recess in the viewers chair. If stereoscopic vision is not required, the tubes may be rotated until their axes are parallel, when the device serves as binoculars. Specification 576,421 is referred to.
