Abstract

845,951. Depth of field indicators. SCHNEIDER, M. C. Sept. 10, 1958 [Sept. 21, 1957], No. 29003/58. Class 98(1) A depth of field indicator comprises a slide d, axially movable by cam means associated with the stop-setting ring s, and carrying markings d<11> observable through a window e in the objective mount. The slide is constrained to move axially by a pin d<3> which engages in an axial slot p<1> in an underlying guide member p. A pin r engages in a curved cam slot sl in the overlying stop-ring s, so that as the stop-ring is turned the slide d is displaced axially, and the appropriate section of the step-like indicator markings, which may be coloured, becomes visible through the window e.
