Riley 'Kineoptoscope' projector mechanism, (1896). Designed by Cecil Wray of the Bradford magic lantern manufacturers, Riley Brothers. Wray's Patent Number 119. Handle turns double-toothed claw mechanism engaging perforations on the film and advancing it one frame for each downward stroke.

The Riley Kineoptoscope 35mm projector was designed by Cecil Wray (1866-1944) of Bradford.

The patent rights for the Kineoptoscope were acquired by Bradford magic lantern manufacturers Riley Brothers who manufactured the projector in 1897. It was advertised as 'Steady as Lumière's. No breakdowns. Most portable and the most perfect known'. As the handle was turned, a double-toothed claw mechanism engaged the perforations on the film, advancing it one frame at each downward stroke.

The machine came in two versions - one which formed part of the magic lantern itself and this example, which was free-standing but required a magic lantern lamphouse to provide the illumination.
