Abstract

19,265. Marsh, A. le R. Sept. 19, 1907, [date applied for under Section 91 of Patents &c. Act, 1907]. Resistances.-A variable heating-resistance forming the walls of a furnace chamber consists of rings 15 of conductive material s u c h as carbon, s u rf ace-oxidized metal, or oxides, sulphides, or other compounds of metals, adjustably compressed together.The bottom of the chamber is a block 17, preferably of graphite, and a ring 14 of similar material is placed above the rings 15. The block 17 and ring 14 are provided with integral terminal posts 19, 18, the former of which carries a bearing for the end of a compression screw 12. A fixed nut 11 is attached to arms projecting from a sheetmetal casing 7, which is supported by legs 8. An inner casing 3 of magnesite, fire-brick, or other insulating-material is provided with an annular cover 4, preferably of asbestos board, secured by bolts 5.
