ABSTRACT:
A long-scale meter movement of the type in which one leg of the moving coil oprates within an annular gap between an outer pole and a cylindrical core. In the new meter movement, the outer pole is integral with the return ring, in a generally circular configuration. The coil support frame is likewise of unitary construction, with a central portion extending through the return ring in the region of the magnet block and having integral coil pivot supports front and rear. The central frame portion has an aperture for the magnet block, with separate supports for the core extending through the aperture in interlocking relation with the frame. The construction of the parts is such that the frame, coil, core and magnet may be fitted together to form a subassembly which is inserted as a unit into the one-piece outer pole and return ring.
