Abstract

1,200,782. Cine projectors; gates. EASTMAN KODAK CO. July 21, 1967 [July 25, 1966], No.17146/70. Divided out of 1,200,781. Heading G2E. In a cine projector for selectively projecting two different films with different frame sizes, the gate 42 comprises an aperture plate 120 having an elongated opening 122 with guide ribs 124 on which may slide a mask 140 with two different framing apertures 144, 142, mask 140 being shiftable between its two positions by a lever 170 to which it is connected by a bi-stable spring 180. Lever 170 is actuated by a control lever 76 which also adjusts the stroke and lateral position of claw plate 38. Plate 120 has two integral H-shaped arms 134 engaging spring-arms 136 extending from housing 10, whereby the plate may be swung open on these arms during re-wind. Gate 42 may be opened against spring 180 by 114 of a multi-armed member 98 pivoting on a closure plate 96 for the pull-down mechanism.
