Abstract
739,470. Kinematograph apparatus. KODAK, Ltd. March 15, 1954 [March 26, 1953], No. 7398/54. Class 97 (1). A film gate is provided with a guiding surface for one film edge, the other edge engaging an inclined surface by which the film is bent out of its own plane to provide a force, due to the film resilience, by which the one edge is engaged with its guiding surface, rails also being provided to guide the film at its two faces, but not at directly opposite points thereof. In the form shown, for exposing half the width of a film, the member 10 has an exposure aperture 12 and claw slot 14 and has a film edge guide surface 30 and rails 31, 32 for engaging the film surface. The member 11 carries an inclined surface 35 by which the other film edge is bent into a recess 36 in the member 10. A rail 33, between the rails 31, 32 engages the other film surface. In a modification the inclined surface 35 is carried on the member 10. The rail 31 is retained but the rails 32 and 33 are replaced by a single rail on the member 11, in the vicinity of the centre line of the film. The member 11 carries, on its outer face, a conical member engaged by a spring which forces the member into position against the member 10.
