November 26: the Reverend Richard Pilkington received "Useful Registered Design Number 5074" for his Pedemascope.[1] This was a variation of the optical toy thaumatrope. It had a card with pictures "painted in two different positions on both sides". This card was placed in the two-part mahogany holder with a handle and a brass pin that would semi-rotate the card when it was twirled, using a bit of iron to prevent full rotation. Transparent or cut-out variations were suggested for use with the magic lantern.[2]
Specific date unknown:
An "Optical Instrument" was patented in the United States in 1869 by O.B. Brown, using a phenakistiscope-like disc with a technique very close to the later cinematograph; with Maltese Cross motion; a star-wheel and pin being used for intermittent motion, and a two-sector shutter.[3]
Thomas Ross developed a small and transparentphenakistiscope system, called Wheel of life, which fitted inside a standard magic lantern slide. A first version, patented in 1869, had a glass disc with eight phases of a movement and a counter-rotating glass shutter disc with eight apertures. The discs depicted ice skaters, fishes, a giant's ladder, a bottle imp, and other subjects. Ross introduced an improved version of his animation device in 1871.[4][5]
