Abstract
The electric resistance heating elements of a heat treating furnace are suspended within a work chamber by hanger rods threaded into nuts which are welded to the inside of the outer wall of the chamber to avoid the need for forming holes through the outer wall. Spacers are supported by adjacent hanger rods and hold thin radiation shields in spaced relation over the entire span extending from rod-to-rod.
