Abstract: 630,786. Calculating-apparatus. LEGRIS, J. A. Oct. 1, 1946, No. 29184. Convention date, Oct. 1, 1945. [Class 106 (i)] [Also in Group XX] A photographic exposure calculator consists of a base member 1 having two or more groups of indications arranged on it, on which is pivoted at 3 a disc 2 having a group of indications which are arranged to register with one of the groups on the base, above which disc is coaxially pivoted at 3 a second disc 4 having indications arranged to register with another group on the base and one or more apertures adjacent which are disposed " Calendar Month indications which register with " Time of Day" indications on the disc 2 visible through the apertures. As shown, the base member 1 carries a " Type of Subject " scale 5 and a " Lens Opening " (f/no.) scale 6, the disc 2 carries a " Shutter Speed" scale 9 and " Hours of the Day " scale 10, while the disc 4 carries a scale 7 of "Sky Conditions and a series of seven "Month" openings 8 adapted to co-operate with the Hours of the Day " scale on disc 2. To account for films of two different speeds the base member may have an arcuate aperture 11 cut in it and may carry a second identical f/no. scale on its back with which a " shutter speed " scale different from the scale 9 and carried on the back of the disc 2 may co-operate. To adapt the calculator for use with a third speed of film, a second slot may be cut in the base 1 and " Lens Opening" indications printed along J and a further scale of " Shutter Speeds" printed on the rear of the disc 2. Instead of this a concentric series of " Lens Opening" scales, one scale for each film speed, may be arranged on the face of the base 1. A calculator for use with films of any speed is provided with a base having an extended arcuate slot in which is mounted a movable insert bearing " Shutter Speeds" and an index co-operating with a scale of " Film Ratings " on the base member. Alternatively, the movable insert may be formed as a separate disc. The uppermost disc may be provided with a single arcuate aperture around which is arranged a " Month " scale co-operating with a single " Hours of the Day" scale on the disc below. For use with a kinematograph camera the " Shutter Speed" scale may be replaced by a " Frames per Second" scale or since this is fixed in most cameras by a single index (corresponding to one film rating only) or a scale of " Film Ratings." To ensure that once the " Month " and " Hours of the Day" scales have been set they will move together while setting " Sky Condition" against " Type of Subject," the friction between discs 2 and 4 is made very much greater than between disc 2 and base member 1.
