Abstract

848,445. Centrifugal switches. VLEET VAN, J. M., [trading as KINDER CO.]. Aug. 27, 1956, No. 26167/56. Class 38 (5). [Also in Groups XXVI and XXXV] A centrifugal switch which governs the speed of an electric motor by opening the circuit of one or more armature windings when the motor overspeeds comprises an electrically insulating rotating support 20 secured either to the armature shaft 12 or to the armature core and carrying fixed and moving contacts 18, 19, the latter via a leaf-spring arm 32 which may bear a weight 33 to produce a wiping action as the contacts mate and break. The motor preferably rotates in the clockwise direction shown, so that acceleration tends to open the contacts more rapidly.
