Title: Improvements in or relating to a retractable vehicle headlight arrangement
IPC: B60Q1/05
Filed: 1956-10-02
Abstract: 837,610. Retractable vehicle headlamps. USINES-CHAUSSON S. A., DES. Oct. 2, 1956 [Oct. 19, 1955], No. 29975/56. Class 75(3) For automatic retraction or projection of a vehicle headlamp 3 into or from a housing 2 in a streamlined vehicle wing or body 1, the lamp 3 is connected by a linkage 4-10 to an electric motor 11 which is controlled both by the headlamp operating switch 16 and by a switch 13 operated by one of the elements of the linkage. As shown the lamp 3 is mounted on one limb of a bell-crank lever 4 swingable about a pivot 5 and pivotally connected at the end 6a of its other limb 6 to a connecting rod 8 which is in turn connected to a crank 9 on the shaft 10 of the motor 11. The shaft 10 carries a cam 14, provided with a flat 14a, which controls, through a follower 15, the position of a two-way switch arm 13 according to the angular position of the motor shaft 10. Fig. 2 shows the circuit arrangement, switch and cam positions with lamp off and in retracted position. To project the lamp from its housing the lamp switch 16 is closed to light the lamp and energize a relay 18 to move a two-way switch arm 19 and close a circuit from the supply 5 via leads 20, 13a, switch arm 13, and lead 22 to the motor 11 and cause rotation of the shaft 10 in the direction of arrow F1. Nearing the end of one half-revolution of the shaft 10, the flat 14a on the cam allows the follower 15, and thereby the switch arm 13, to drop and thus break the circuit to the motor 11. However the motor feed is maintained by a switch 12 which is closed, by means on the shaft 10 or crank 9 immediately. on movement thereof from the rest or the operative positions of the lamp 3 to supply the motor via a lead 21, until the half-revolution of the shaft 10 is completed and the lamp 3 is fully projected. At this point the switch 12 is opened, Fig. 5 (not shown). For retraction of the lamp 3, the switch 16 is opened, de-energizing the relay 18 and thereby causing return of the switch arm 19 to close the motor circuit via leads 20, 13d and 22 and rotate the shaft 10. This circuit is quickly broken by lift of the follower 15 to move the switch arm 13 to the Fig. 2 position, but the circuit to the motor is again maintained via lead 21 by closing of switch 12, until the retraction half revolution is completed and switch 12 is opened.

Abstract: 1,132,958. Photographic cameras. EASTMAN KODAK CO. July 7, 1966 [July 12, 1965], No.30543/66. Heading G2A. A photographic camera having a socket with a rotatable portion 23 for receiving flash-cubes is further provided with a cover 16 for the socket, opening of the cover tensioning means for indexing the portion 23. As the cover is opened to the position shown a flexible cable 33 causes a drum 35 to rotate clockwise (looking down on Fig.3) and this rotation tensions a return spring 36 and a drive spring 41 one end of which is attached to the portion 23 and the other end to a ratchet member 39 carrying a rotatable post 40. A flash-cube is inserted and an exposure is made by depressing a button (15) Fig.1, (not shown) thereby lowering an arm 46 until it clears a lug 44 on the portion 23. Drive spring 41 then rotates the portion 23 clockwise a little way until the same lug 44 is engaged by a tab 49. When the button (15) is released, the arm 46 rises to the right of the lug 44 and lifts the tab 49, thereby permitting portion 23 to be rotated clockwise by the spring 41 until the next lug 44 (there are four in all) engages the arm 46. After four exposures (i.e., after three indexing operations), the post 40, which is rotated with the portion 23, re-engages an eccentric stop on the member 39 to prevent further indexing. The flash-cube is removed and the cover 16 closed. The tensioned return spring 36 then rotates the drum 35 counter-clockwise independently of the member 39 and the cable 33 is rewound on to the drum. In another embodiment Figs. 4, 5 (not shown) the cover (16a) is mounted for lateral sliding on the camera body. It is stated that opening of the cover, in both embodiments, may also be used to adjust the shutter for flash operation.
