Abstract: 1,179,712. Photographic cameras. EASTMAN KODAK CO. April 6, 1967 [April 6, 1966], No.15858/67. Heading G2A. A camera objective comprises a focus setting member 2, an exposure time setting member 36, a diaphragm aperture and film speed setting member 20, a carrier member 56 for the diaphragm aperture scale 58 and the film speed scale 62, means for releasably coupling the focus setting member 2 and the diaphragm aperture setting member 20 when the exposure time setting member 36 is set for flash exposures, and second means for releasably connecting the diaphragm aperture setting member 20 and the carrier member 56, this connection being automatically uncoupled to permit relative rotational movement between the members 20 and 56 to set the film speed. A leaf spring 14 is attached at one end to the focus setting member 2 and its other end 16 is bent to engage the inner periphery of the diaphragm aperature setting ring 20. The spring 14 passes through an arcuate slot 48 in a plate 28 of a shutter housing 30. This plate 28 rotatably supports a lever 24 which is adapted to engage the spring 14 for daylight exposure settings. A pin 32, attached to the lever 24, moves in an arcuate slot 34 in the exposure setting member 36. When the member 36 is set for flash photography the pin 32 is urged into a recess 38 in the slot 34, so that the lever 24 can rotate to release the spring 14. The ring 20 is then rotated until the end 16 of the spring 14 snaps into a recess 18 in the ring 20 when the members 2 and 20 can be rotated together. The spring end 16 is withdrawn from the recess 18 by rotating the exposure setting member 36 to the daylight setting range so as to rotate the lever 24 against the spring 14. The releasable coupling between the members 20 and 56 comprises a spring 66 secured at one end to the member 56 and having at its other end a tongue 70 which is urged into any one of a series of grooves 72 provided on the inner periphery of the member 20. A pin 74 attached to the spring extends through an opening in the carrier member 56 and, when manually depressed, withdraws the tongue 70 from a groove 72 to permit relative rotation of the members 20, 56. The diaphragm aperture is set in response to a known exposure control mechanism.
