Steam iron water gauge

Abstract From the Canadian patent

An iron having an exterior wall portion which at least partially defines an internal water reservoir and a cover member secured and peripherally sealed to the outer surface of the exterior wall portion to form therewith a chamber communicating with the reservoir through relatively small spaced-apart openings in the exterior wall portion. Both the cover and wall are preferably of a heat resistant plastic. The exterior wall portion is aligned to cover or conceal the openings which are positioned so the water level in the reservoir is indicated through a transparent portion of the cover member when the iron is disposed in either a horizontal ironing position or a vertical filling position.
