Abstract

23,860. Berry, A. F. Oct. 18. Heating by electricity; resistance ovens.-A heater contains a strip or wire of high resistance wound in one layer, enclosed between mica or other thin insulating sheets, which are held between metal coverings forming an open structure, special means being provided for bringing both ends of the resistance to one end of the heater. In the form shown, a core consisting of a split tube b is fitted over, and optionally soldered or brazed to an inner tube a, so as to leave a longitudinal groove, and is covered with mica. A resistance strip d is laid along the groove and wound back, the two ends being connected to terminals on a support f, which may be screwed into a kettle, oven, or other apparatus. The resistance is covered with thin sheet-mica, over which strip copper or other metal h is wound. The turns of the strip h are joined by soldering or otherwise, or a thin metal tube i may be fitted over it and deformed to fit tightly between the wrappings h. A tube j, having a flange j' at one end and an aperture k at the other, may be inserted into the heating- element to promote fluid circulation, or the heating-element may itself have apertures for this purpose. Alternating current may be used, the heating being in this case partly by currents induced in the tubular parts. Specification 23,861/12 is referred to.
