Abstract
20,923. Gold, E. E. Sept. 11. Resistances.-Electric heaters are made with resistant wire coiled into a small helix, whieh is itself generally coiled to form a large helix ; this is supported internally or externally by open supports. The wires, or preferably the supports, are covered with thin insulation, such as vitreous enamel. Various supports are specified. In one arrangement, Fig 3, the helix A encloses one or more insulated supporting-wires a, which are secured at their ends by nuts to discs, such as C, connected by bars E ; a guard wire D may be coiled within or on the bars E, and may be insulated to serve as additional resistance. Instead of the tubular arrangement, the supporting-wires a may otherwise be formed into a flat spiral or zig-zag. In another arrangement, Fig. 14, the conducting-helix A is held by its elasticity on or within a helically-coiled insulated supporting-wire a, both positions being shown.
