Abstract
1.06,373. Henley, J. Aug. 14, 1916. Kinematograph apparatus. - Kinematograph pictures with stereoscopic effect are presented to view by projecting or exhibiting the elements of each stereoscopic pair in succession and providing means by which one eye of the spectator has a clear view of the appropriate picture and the other eye has a dim view of that picture, the clear and dim views alternating from eye to eye with successive pictures. The film may be viewed directly in a cabinet containing an electric lamp and a pair of viewing lenses, a steel ribbon having openings alternating with and spaced from groups of fine perforations being fed across the lenses simultaneously with the feed of the film so as to provide the desired views and also to act as a shutter. The steel ribbon may be replaced by an opaque celluloid or gelatine ribbon having alternating, spaced, transparent, and semi-transparent portions, or by an oscillating member having similar openings &c. According to Provisional Specification 13562/16, the oscillating member has two openings between which is a group of perforations. Colour screens may be provided for producing multi-colour effects. The pictures when projected are viewed with the aid of an apparatus such as shown in Fig. II which is held by the spectator and comprises a coloured gelatine or celluloid sector A mounted on a rod B which is vibrated in synchronism with the film feed movements by means of electro-magnets C and a pole-piece D, the sector resting before, each eye alternately during the projection periods. The currents passing to the electro-magnets are controlled automatically by the projection apparatus. The sector A may comprise two portions of complementary colours, when the alternate pictures projected are separate colour records, each portion resting before one eye so as to serve as the colour screens. Each series of alternate pictures on the positive film is printed from one of two negative films exposed simultaneously in two cameras, the axes of which are directed to the principal subject of the picture. According to Provisional Specification 11449/16, the background of one series of alternate pictures may be almost or wholly eliminated.
