Abstract

232,204. Kodak, Ltd., (Assignees of Tessier, J.). April 9, 1924, [Convention date]. Finders ; lens fittings.-In a camera wherein a device, such as a colour screen, portrait attachment, or apertured diaphragm is provided for modifying the light passing through the objective, the device is mounted on a lever carrying at its other end a signal which is visible in the view finder when the device is adjusted over the objective. As shown, a lever 19 pivoted at 18 in a casing 14 attached to the front of the camera carries at one end the device E<c> for modifying the light, and at the other end an indicator, such as a coloured screen Er adapted to rest in front of the finder aperture 26 when the lever 19 is swung over, by means of a handle projecting forwards from its pivot, so that the device E<c> rests in front of the objective aperture 27. A spring 23 retains the lever in the operative or inoperative position. The finder comprises a positive lens 4 on the camera front, an inclined mirror 5, and a viewing lens 6 in a recessed opening in the camera top.
