Abstract

12,085. Bright, R., and Wright, J. M. W. June 3. Magic-lantern apparatus.-In lanterns for producing scenic, signalling, or advertising effects, in which screens are passed across the lantern aperture, the driving-gear of the screens is brought into operation by electro - magnets. Screens d in a casing a are suspended by a nut g from a screw h. The energizing of a magnet r causes its armature q to bring a clutch p into gear with a wheel j, which is rotated through gearing k, o by a motor n. The clutch p being on the shaft of the screw h, the screen d corresponding to the magnet r is moved across the aperture c. The driving-arrangements for the screens may consist of endless cords passing over pulleys or of rack-and-pinion apparatus. The screens are usually channel-shaped.
