Abstract: 846,028. Photographic apparatus. INTERNATIONAL POLAROID CORPORATION. Aug. 16, 1957 [Sept. 6, 1956], No. 25902/57. Drawings to Specification. Class 98(1) A device for mounting as in a camera and operating a self-developing film assembly therein comprises a pair of pressure-applying members and a pair of engagement members which latter are movable towards each other for arresting movement of the assembly, all four members being mounted on a single support. The device thus differs from prior similar constructions involving separate supports, usually relatively movable sections making up a camera casing, and each section having one of the members of each pair. An Example of the device and camera features, described with reference to 20 figures (not shown), illustrates performance of the engagement members when the assembly which consists of a sheet having photosensitive areas for sucessive exposures and another sheet having rupturable containers of developing fluid has been drawn through the pressure-applying members to release the fluid to act on a first of the photosensitive areas and leave the next one of these in exposure position, the assembly having means at intervals along its length to co-operate with one of the engagement members for the arresting action. The camera includes a chamber for accommodation of the assembly portions during development and the latter is normally of the type producing a direct positive by transferreversal. Various features to facilitate loading and correct operation of the camera are described. Specification 684,592 is referred to.
