ABSTRACT:
In an electric flatiron with a soleplate and central upstanding boss and having a handle having a temperature adjusting lever in the front of the handle, an improvement is provided in the temperature regulating assembly that comprises a snap action thermostat which is supported on the boss with a substantially vertically movable adjusting screw to vary the thermostat settings. An insulated cap is provided on the top of the screw and the cap has an outer splined surface. A rod is connected at one end to the temperature adjusting lever forward of the screw for rotation by lever movement for setting temperature. The rod has an offset portion at its other end loosely fitting in a driving engagement over the splined surface so the offset slides vertically over the splined surface forming a universal-like connection as the rod is rotated by the lever to turn the screw and vary the thermostat setting of the iron without undue backlash.
