Patent GB-349904-A (GB)
Abstract: 349,904. Controlling motor vehicles. NAFZIGER, R. LE R., 118, West 47th Street, Kansas City, Missouri, U.S.A. Jan. 21, 1930, No. 2145. [Class 79 (v).] A switch S, Fig. 1, in the ignition circuit of a motor vehicle is arranged to remain in the operated position while the driver is in his seat and is automatically placed in inoperative position, after the lapse of a predetermined time, when the driver leaves his seat, so rendering the ignition circuit ineffective. The switch contacts may also be controlled during the starting up of the engine by a push button 66 in front of the radiator 67 which operates through a Bowden wire mechanism 65. As shown in Fig. 7 the switch comprises a plunger 31 working in a dashpot 30 filled with liquid 41 and provided with a byepass 37 the flow through which can be regulated by a screw 40 adapted to be adjusted from outside the switch casing by removing a cover screw 42. The plunger 31 is connected through an operating rod 32 to a guided plate 44 and is depressed by the driver's seat bearing on a plate 51 mounted on rod 47 passing into the casing and terminating in a plate 49 bearing against the plunger plate 44. Both rods 32 and 47 are surrounded by retractive springs 45 and 50. During the downward movement of the piston it is practically unimpeded as the liquid passes through a non-return ball valve formed therein. During this motion an arm 55 on the plate 44 engages the V portion 56 of a contact spring 60 so disengaging it from the spring 61 and rendering the ignition circuit effective. Alternatively with differing ignition circuits the depression of the plunger may cause engagement between two separated contact springs. In the return movement the piston moves slowly at a rate permitted by the flow of liquid through the byepass so that the driver may leave his seat for a short period before the ignition circuit becomes ineffective. The arrangement for controlling the contacts during starting up of the engine is shown in Fig. 3 and comprises a pivoted hook 68 attached to and operated by the Bowden wire 65a which enters a slot 70 when the spring-retracted button 66 is depressed so forcing down a plunger 71 to engage the projection 56 of the contact spring 60 as shown in Fig. 4. The plunger is provided with a notch to keep the apex 56 in engagement until released by the depression of the main plunger, when the plunger 71 is retracted within the arm 55 by the spring 74. In a modification also described, Fig. 9 (not shown), in which the seat switch is opened when the driver is in his operative position, the ignition circuit is controlled through an electromagnetic switch the circuit of which is in turn controlled by a switch of the type already described.
