Abstract
611,470. Centrifugal switches. BRITISH THOMSON-HOUSTON CO., Ltd. May 1, 1946, No. 13181. Convention date, May 1, 1945. [Class 38 (v)] In a centrifugal switch, the contacts (not shown), which may be as in Specification 500,778, are normally held closed by a collar 8 slidable on the drive shaft 9 and having projections 10, 11 between which the rounded parts 14 of pivoted weights 12 are arranged to roll on one another. The weights 12 are also pivoted by lugs 15 and slots 16 to plates 17 which are themselves pivoted at 18 ... 22 to a supporting plate 2 rotatable with the shaft 9. The weights 12 are urged inwards by springs 24 attached to lugs 25, 27 on the plates 2, 17, respectively, their inward movement being limited by lugs 28 on the plate 2. As the weights move outwardly, the collar 8 slides to the right, as seen in Fig. 1, until at a predetermined speed it allows the contacts to open.
