Abstract

547,964. Centrifugal switches. HEENAN & FROUDE, Ltd., and WALKER, G. H. May 27, 1941, No. 6759. Addition to 544,235. [Class 38 (v)] In a modification of the parent Specification, a universal joint interposed between the weighted lever 41 and the adjusting device comprises a connecting rod 60 with spherical ends bearing in cups 62, 63 secured, respectively, to the lever 41 and a member 64 which is moved longitudinally by rotation of the screw 65. The lever 41 is fixed to a spring 69 secured to the contact carrier 31, and an additional biasing spring 72 acts upon the lever 41 at high speeds.
