摘要： A motion picture projector is provided with a manually shiftable mode controller assembly for selecting various operational modes and apparatus for the automatic threading and rewinding of film. The operative mechanical components of the projector are mounted on a unitarily molded housing including molded structures and portions that independently and cooperatively with other control assemblies and interfitting structures provide features and improved operational characteristics. The molded housing interfits with a take-up reel cover, a control assembly cover and a rear cover that rotatably engages a carrying handle. Structure to define a film path, an automatic threading assist structure, a film speed detent structure and a position defining structure for the mode controller assembly are also provided by and integrally molded with the housing.

摘要： A drive control mechanism for selectively actuating a motion picture projector to several operational modes to transport film between a supply device and a take-up device is provided that utilizes a brake mechanism to stabilize a selective driving assembly and to prevent film spillage.The drive control mechanism is provided with a mode controller that translates various positions into predetermined axial and rotational positions and movements that is coupled through actuating members to control a dual clutch assembly driven by a unidirectional input. A brake assembly control device is also coupled to the mode controller and conditions the operation of the brake assembly.The brake assembly is a pivotally operated dual brake shoe arrangement which is pivoted into operative contact with the dual clutch assembly wherein the brake shoe arrangement is selectively operated in and between predetermined operational modes as the brake assembly control device is axially shifted and rotated in response to the mode controller.
