Abstract
1,273,014. Actuation of switches. ALLMANNA SVENSKA ELEKTRISKA A.B. 30 Sept., 1969 [1 Oct., 1968], No. 47905/69. Heading H1N. An operating spring 5 is coupled to the operating shaft 1 of a circuit breaker and to the shaft 9 of a charging device by way of an endless belt 11. The contact (not shown) is closed by a rod 4 driven by a cam 2 and follower 3 and latched by 19. One complete revolution of the cam closes the contacts and charges an opening spring. A catch 18 is momentarily released to initiate the closing movement and stops the shaft 1 after one revolution. The shaft 1 carries a wheel 13. A motor 7 drives a second wheel 17 non reversibly by a worm and pinion drive 8 or with a pawl and ratchet mechanism 9, 10. The spring bank 5, comprising a plurality of tension springs, is coupled to a third wheel 12. A chain 11 joins the wheels, passing over a fourth wheel 16 and being held in tension by a light spring 15 and another wheel 14. With such an arrangement no part of the charging device need move with the contacts and closing time is minimal.
