ABSTRACT:
In a steam iron having a horizontal slot in the upper forward portion of the handle and a temperature control rod with its upper end disposed centrally of the slot, an improvement is provided in the temperature control assembly for operating the rod. A semi-circular crowned disc spring plate is provided with a projection and a depressed hollow recess in the crown surrounds the rod and has an upper annular bearing surface around the recess. The spring plate curves down from the bearing edge to the plate periphery and is fixed in the slot against withdrawal by a projection abutting the inner handle. A generally half-circular polypropylene dial plate support is provided with U-arms straddling the rod and with upper projections on each arm and in the bight of the U for locking the dial support in the handle slot. There is provided an integral rotatable thermoplastic polyester control lever with an external knob at one end and a recess at the other, the recess having opposite annular bearing surfaces and nesting in the spring plate recess. The lever has smooth facing surfaces abutting both the spring plate bearing surface and the underside of the dial plate, the entire combination being such that the elements are biased upwardly in a sandwich assembly by the disc spring plate to provide an easily assembled, long wearing and smooth operating three-piece control assembly.
