Abstract
618,731. Electromagnetic relays. AUTOMATIC ELECTRIC LABORATORIES, Inc. Nov. 23, 1946, No. 34792. Convention date, Nov. 23, 1945. [Class 38 (v)] In a contact-spring assembly for a relay, the fixed springs 50, Fig. 5, have S-shaped ends carrying twin contacts 52 and are arranged, so far as their portion 59 is concerned, to the side of the movable springs 60, Fig. 8. Two screws 46 pass through holes 55 in the fixed contact springs and similar holes in the movable springs. In the arrangement shown in Fig. 1, a second set of fixed and movable springs is also provided operated by the same armature, and this Figure also shows a makebefore-break contact arrangement, one spring 70 of which is shown in Fig. 10. The insulators between the springs are shaped as in Fig. 12, the portion 41 extending along a fixed spring so as to shorten its effective length. The.natural periods of vibration of the ends of the contact springs are also made to differ. Fig. 6 shows an alternative form of movable contact spring.
