Abstract

211,086. Cox, A. M. Nov. 6, 1922. Transmission mechanism. - To generate periodic electric impulses for actuating instruments such as speed indicators as described in Specification 210,854 a permanent annular magnet a having a gap b filled with non-magnetic material is secured to the wheel or clamped on the shaft of which the speed is to be measured, and a wire-wound stator g is supported by a bracket g<1> close to the magnet. The leads from the stator are connected to the instrument. Specification 28139/07 also is referred to.
