Abstract

286,437. Doht, W. Nauck, W., and Predari, A. Schmidt-. Feb. 15, 1927. Wire resistances, encased; mounted on flat surfaces.-A resistance wire is compressed between two slabs of wood or artificial wood rendered fire-resisting. Proferably the wire is forced into the slabs by pressure, but the slabs may be grooved for its reception if necessary. The heater may be treated with water glass or other composition to close the pores of the wood. The wire may be bare or insulated. Sheets of mica or like insulating material may be placed on. each side of the wire, or the wire may be sewn on to a sheet of insulating material and the whole placed between the slabs. Fig. 2 shows a heater of the type described, the wire is being disposed in a zig-zag and holes 5 being formed in the slabs to increase the radiating surface.
