Abstract
520,009. Photographic plate or film holders. GODDARD, A. Jan. 24, 1939, No. 2360. [Class 98 (i)] A holder for flat films or plates, which may be used with the film back of a roll film camera or instead of the dark slide of a plate camera, has light-tight slits in two opposite edges through which a flexible shutter passes. The holder has a base 1 to which is attached a mask 4 as of felt. in the aperture of which the film or plate 2 is placed. A second mask 5 having lateral ribs 6 is attached to the mask 4 along two opposite edges. Its other two edges are situated as shown beyond the mask 4 and carry below them strips 8, slightly spaced from the ends of the mask 4, to provide narrow passages for the flexible shutter 9. The shutter comprises a sheet of flexible material with an opaque area at one or each end, and either an intermediate aperture or one or more intermediate transparent areas which may be colour filters. For use with a rollfilm camera, the ends of the shutter may be tapered to fit the film spools. In a modification for use with a plate camera, the edges of the . mask 5 project laterally to provide slides which fit into the vertical guides provided on the camera for dark slides.
