Abstract
696,625. Speed governors. WESTERN ELECTRIC CO., Inc. Nov. 30, 1951 [Dec. 8, 1950], No. 28113/51. Class 57 [Also in Group XXXIV] In a governor for telephone calling dials, the driving torque from a shaft 11 is transmitted to arcuate weights 19, 20 through the arms 13, 14 of a drive-bar 12 secured to the shaft 11, the arms 13, 14 engaging notches 21, 22 in the inner sides of the weights with a cam action which assists centrifugal force in urging the weights outwardly about their pivoted ends 17, 18 against the restraint of a spring 23, the weights engaging the side of a stationary cup member 10 to control the rotation of the shaft 11. Contact between the weights and the cup 10 is made through studs 26, 27 on the former; the weights are carried by a fly-bar 15 freely mounted on a shoulder on the drive-bar 12 and the spring 23 is of the flat coil type.
