Abstract
386,888. Telemeter and view-finder for photographic cameras. LEITZ GES., E., Optical Works, Wetzlar, Germany. July 11, 1932, No. 19566. Convention date, Sept. 10, 1931. [Classes 97 (i) and 98 (i).] A camera is fitted with a telemeter provided with a reflector such as a prism adapted to be moved from an inoperative position into an operative position adjacent to the observing window of the telemeter so that the window may be viewed either directly or in a direction inclined to the axis of the camera, As shown, a telemeter having a half-silvered mirror D and an adjustable reflecting prism E (which may automatically control the focusing of the camera lens) is mounted, together with a lateral view-finder H on the top of a camera A. A reflecting prism L mounted in a frame J pivoted to the finder H may be swung down opposite the observing window F of the telemeter, so that when the object is viewed laterally in the finder H, its range may be determined from the same direction by observation in the prism L, For direct viewing, a, finder B, C fitted in the telemeter casing is used, and the prism L is swung up into its inoperative position, Fig. 1. A stop K limits the angular movement of the prism frame J.
