Abstract

10,977. Kamm, L. May 3. Optical-projection apparatus. - A condenser cell or mount for a projecting-lantern has each lens of the condenser carried in a detachable slide or carrier. Each lens-carrier comprises a channelled frame n, a plate l fixed to the frame n, a movable plate l<1> adapted to slide in the channelled frame n, the plates l, l<1> being curved and grooved to engage the edge of the lens i and to hold the lens between them, and a spring p for holding the movable plate l<1> against the lens i when in position. A curved lug r is used for removing each lens from the cell.
