Abstract

472,966. Kinematograph projectors. ZEISS IKON AKT.-GES. March 30, 1936, No. 9461. Convention date, April 2, 1935. [Class 97 (i)] A driving motor 2 is attached externally by a flange to the outer wall of a projector housing 1, and the housing of a compressed air generator, supplying cooling air to the film track &c., and driven by the motor, is carried by the motor housing. As shown in Fig. 1, the generator 3 is carried bv a bracket 6 secured to the motor housing, and is connected, directly or through a coupling, to the motor shaft 5. Fig. 2 shows the housing 44 of the generator so formed that it may be directly mounted on the motor housing. The air passes to the projector through a conduit 7.
