Abstract
167,539. Nolan, J. April 30, 1920. Heating by electricity; electric radiators.-An electric heater for immersion in the liquid of, for example, a radiator, comprises a case of circular rectangular or other shape closed at one end and fittad at the other with a cap carrying the terminals for the leads to electric heating- elements contained within the case. In the form shown the case consists of two D-shaped portions a facing each other and attached at one end to a bush c which screws into the radiator. Each heating-element e comprises resistance wire wound round mica plates and protected on each side by mica plates. These elements are clamped between metal plates f, one. of which is curved to fit the D-shaped case. The ends of the elements may be rabbeted so that a number may be connected together. The radiator may have a tube g fitted at the other end to diminish the quantity of water and so to permit the temperature to be raised more quickly. A nipple h with an opening i divides the lower part of the radiator into two chambers. The tubes a have tapered portions j so that, as the heating-elements are pushed in, they are forced into good contact with the sides of the tubes.
