Abstract

330,701. Donelli, A., and Ottico Meccanica Italiana Soc. Anon. April 22, 1929. Kinematograph apparatus.-In a projector provided with automatic lubrication using one or more chains, which may be simple or provided with small buckets, in the transmission mechanism, the chain 1 dips in a lower main tank 4 and the oil is carried to the upper chain wheel from which it drips into a tank 6 from which it is distributed by pipes 7 and 8 to the mechanism. Pipe 7 lubricates the shutter driving mechanism 9 and 29 and pipe 8 supplies a tank 10 fitted with a filter 13 which lubricates the intermittent gear 11 and 12.
