Abstract
416,771. Centrifugal speed-indicators. COOPER-STEWART ENGINEERING CO., Ltd., CHURCHILL, C. M., and GREAVES, L. W., 136, Long Acre, London. Jan. 6, 1934, No. 565. [Class 106 (iii).] Two grooved weights H slidable radially on bars J on opposite sides of a rotating spindle D are controlled by sets of flat springs K which come into action in succession to oppose centrifugal force, the grooves h<1> in the weight operating a pin connected to the pointer. The spring leaves of varying lengths abut against rigid splayed members b<1> carried by the base B to which are also secured the bars J. The spindle D is rotatably mounted in a sleeve C rigid with the base B, a grooved pulley d<5> on the spindle being frictionally connected by a spring F to the base. Lateral extensions h<3> on the weights H carry pins engaging slots in arms on a member G capable of a small angle of rotation about the sleeve c whereby simultaneous but opposite movement of the weights is ensured. The curved grooves h<1> in the weights operate a pin on a cam or gear wheel arranged eccentrically to the dial and connected by gearing to the spindle of the pointer. Specification 109,160, [Class 106 (iii)], is referred to.
