Abstract

963,330. Centrifugal governors. TESLA NARODNI PODNIK. May 14, 1962 [Aug. 10, 1961], No. 18438/62. Heading G3B. A centrifugal governor for controlling the speed of the dial of a telephone subscriber's set, comprises a brake drum 7 secured to the base plate of the dial and within the brake drum and fixed to the spindle 9 of the dial, a rotary brake control body 1 made in one piece from resilient plastics material e.g. a polyamide, having integral brake arms 3 provided with braking faces 5 and adapted to flex outwardly under centrifugal action whereby the faces 5 enge the drum 7, the brake arms 3 being connected to the body 1 by flexible bridges 6 whose flexibility is such that their restoring force is negligible with respect to that exerted by a metallic spring 10 having its ends secured in the arms 3. Cylindrical metal weights 4 may be pressed into the arms 3 to give the required centrifugal force and the spring 10 is secured to a ring 11 on the spindle 9, the ends being held in openings 12 in the weights 4. The material used for the body of the governor may include a filler to increase friction between the faces 5 and the brake drum 7, which is also made of a synthetic material with a filler. The body 1 and arms 3 may alternatively be made of synthetic material with a high density metal powder filler in which case the weights 4 are dispensed with. The faces 5 may be the same width as or less than that of the arms 3.
