The furnace is motor tilted, in all sizes, for pouring, butis arranged so that it can be tilted by hand in emergency ifthe motor fails to operate. The smaller sizes of furnace arebuilt for hand operation only, if desired. All parts of thetilting mechanism, including gears and motors, are arrangedso that they do not come beneath the furnace and there-.

The main electrodes are arranged for automatic regu-lation and also, in every case, so that they can be regulatedby hand in case the regulators or motors should requirerepair. The importance of power control is universally recog-nized, especially when refining operations are carried the Booth-Hall electric furnace the power input can bemaintained at any point from one-fourth to full load bymeans of proper voltage reduction and control switches.
