Abstract: 1,269,098. Photographic cameras. EASTMAN KODAK CO. May 6, 1969 [May 6, 1968; May 22, 1968; May 31, 1968], No. 23067/69. Heading G2A. A photographic camera comprises a movable socket for receiving a multi-lamp flash unit; drive means for sequentially moving the socket to place the lamps of a received unit in an operative position; and a multi-armed member having a first arm engageable by film winding mechanism, a second arm for operating the camera shutter, and a third arm engageable with the socket drive means. In a first embodiment, Fig. 2, the multi-armed member 36 is provided with a fourth arm 76. Film is wound on by moving film advance lever 30 to the dotted line position, a pin 35 engaging the first arm 38 to rotate the member 36 clockwise against spring action. This movement causes the second arm 42 to ride over a latch 45, and causes the third arm 54 to displace a socket indexing slider 50 to the right against a spring 52, an arm 64 of the slider over-riding a wedge shaped ratchet tooth 62 on socket disc 60. When the lever 30 reaches the end of its film advancing movement, the arm 42 is prevented from moving anti-clockwise by the latch 45, and the slider 50 prevented from moving to the left by the arm 64 which by this time has engaged the next tooth 62. Also, a pawl 68 of a control lever 70 engages a notch 66 in the socket disc 62 to prevent the socket and inserted flash cube from rotating. The winding lever 30 then returns to its solid line position. To make an exposure, shutter trigger 31 is depressed, thereby bringing an extension tab 80 thereof into engagement with the edge of a notch 66, Fig. 6 (not shown). The arm 42 is released since the latch 45 is on the trigger 31, hence the shutter and a flash synchronizer are operated. As the multi-armed member 36 rotates, the fourth arm 76 releases the pawl 68 from the notch 66, the disc 60 being held by the tab 80 until the trigger 31 is released. This moves the tab 80 out of its notch 66 and the disc 60 rotates to the position shown as the slider 50 moves to the left under spring action, the arm 64 remaining engaged with the tooth 62. In a second embodiment, Fig. 9, the multi-arm lever 136 is shown in its cocked position. This has been attained by rotation of the lever 30 as described above. The second arm 142 is locked in position and the slider 150 moved to the right (i.e. to the position shown) by the third arm 154 also as described above, but in this case the slider is locked in position by a resilient latch member 180. Depression of the trigger 31 causes opening of the shutter as before. The third arm 154 moves anti-clockwise and, after a delay in which the shutter is opened, engages an end 184 of the latch 180 to free the slider 150. A portion 162 of resilient drive member 164 attached to the slider engages the socket base 160 as the slider moves to the left and rotates the base through 90 degrees, Figs. 11, 13 (not shown), the base coming to rest with portion 163 adjacent surface 4 of the base. A resilient member 170 is provided to prevent socket rotation while film is advanced. In a third embodiment, Fig. 17, the socket 260 is rotated as film is wound on. First and second arms 238, 242 and winding lever 30 operate as described above, the mechanism being shown in the cocked position. As the cocked multiarmed member 236 is released, the third arm 254 moves to the left and the slider 250 moves to the left under spring-action. A spring drive member 264 is, by this movement, freed from contact with face 261 of the socket disc 260 and with a projection 251 of the slider 250. Disc 260 is prevented from anti-clockwise motion by a spring pawl 273. As film is advanced and the third arm 254 moved to the right, the drive member 264 engages surfaces 262, 263 and is re-engaged by the projection 251, Fig. 23 (not shown). As the slider 250 is moved back to the position shown, the member 264 rotates the disc 260 through 90 degrees clockwise.
