ABSTRACT:
An improved ceramic heater support and spacer block, for use in an electrical heating element, is constructed to increase the amount of electrical wire per unit space available for plug-type conventional heating units. The ceramic heater support block, T-shape in plan, has spaced end faces and a groove in its under surface extending between and perpendicular to the end faces which receives a crossbar interposed between support elements. Each block has a support boss of a width adapted to extend between the strands of a section of heating wire. Each block has a pair of spacer bosses, adjacent to its other end face, which extend laterally outward of the support boss. Each heating wire section of a group is mounted upon the support boss of each block, upon a crossbar, with the spacer bosses extending between and outward of adjacent sections. The one strand of adjacent heating wire sections is transversely interconnected below a row of support blocks mounted upon an adjacent crossbar.
