Abstract

461,989. Current and pressure meters. LUCAS, Ltd., J., and TAYLOR, H. C. Aug. 28, 1935, No. 24043. [Class 37] A moving-iron meter in which the armature is influenced jointly by the field of a permanent magnet and that of the current to be measured comprises a one-piece assemblage consisting of a non-magnetic frame carrying the armature, a permanent magnet supported on one side of the frame and a soft-iron loop on the other side, the loop receiving the current conductor. The frame consists of parts a ... d riveted together and carrying the armature f in bearings one of which is accessible through an aperture in the soft-iron loop m. A short permanent bar magnet is supported by protuberances l and clips k on the frame plate b. Specification 295,714, [Class 37], is referred to.
