Abstract
17,955. Topp, M. N. Aug. 7. Optical projection apparatus, stereoscopic. A hand appliance for the observation of the pairs of images necessary for stereoscopic vision thrown in quick succession upon the same screen as by a kinematograph, consists of a rotating shutter driven synchronously with the projecting - apparatus to expose the observer's eyes momentarily and in succession for the purpose of limiting the vision of each one to the appropriate series of alternate views. The device consists of a frame a provided with a handle b, eye-openings d, e, and a screen c rotated in front of these openings synchronously with the shutter of the projector, by means of a motor carried in the device. The dull, almost opaque screen c increases in thickness towards the periphery, and is directly connected to the shaft of the motor. The armature and the field windings are fed tbrough wires placed in the handle b. Perfect synchronism may be obtained by turning the whole motor on its bearings in the rear wall of the casing h by means of a spring s which slides upon the back wall of the casing. Friction is minimized by having a tapering pivot of conducting- material o rotating on a bearing in the spring n, which is connected to one of the wires, the rotary pin being connected to one end of the armature winding.
