Abstract
603,047. Centrifugal switches. SOC. L'AIR LIQUIDE, SOC. ANON. POUR L'ETUDE ET L'EXPLOITATION DES PROCEDES G. CLAUDE. Nov. 16, 1945, No. 30870. Convention date, Dec. 14, 1944. [Class 38 (v)] A centrifugal switch has a rotor 2, mounted on the end 1 of the rotor of the motor it controls and having a radial slot 5 containing an L- shaped plate 6 pivoted at 7. On an increase of speed, the plate 6 presses against a ball 8 and, through a plunger 10 and a lever 11, separates contacts 15, 31 against the action of a spring 17. One end of the spring is attached to a lever 16 pivoted to the lever 11 and fulcrumed about an adjustable knife edge 18, the other end of the spring being attached to a seating 21, which is adjustable by means of a lug 24 engaging a helical groove in a rotatable member 23. A scale 25, co-operating with a pointer 26, indicates the angle through which the member 23 is rotated to obtain a given motor speed, which angle is proportional to the square of the speed. The spring tension is adjustable initially by means of a screw 28 to compensate for irregularities of manufacture. The rotary portion of the governor is balanced by a second L-shaped plate 29. In a modification, Fig. 3 (not shown), the knife-edge 18 is carried by the lever 16 and co-operates with an adjustable seating.
