Abstract

378,347. Cameras. ZEISSIKONAKT.- GES., 72, Schandauer Strasse, Dresden, Germany. March 7, 1932, No. 6877. Convention date, Sept. 14, 1931. [Class 98 (i).] In a camera having a screw-threaded focusing sleeve which carries the lens and controls the adjustment of a telemeter which is used for focusing purposes, the focusing sleeve has a control cam for controlling the telemeter. The focusing sleeve 7 carrying the lens 4 is screwthreaded at 6 and has a control cam 5 against which the pivoted arm 3 carrying one of the mirrors 2 of the telemeter 1, 2, is resiliently pressed. The focusing sleeve is rotated by gearing from a thumb-wheel 8 projecting outside the camera casing.
