Abstract: A control device for controlling the operation of an object of cooking such as a stove or the like. The presence of a user in the area of the stove is detected. When the user is present, the stove operation is enabled. After the user has been absent from the area for a first predetermined time, the stove is temporarily disabled, an again enabled when the user enters the area. If the user is absent from the area of the stove for a second predetermined time, the stove is permanently disabled, so that it cannot again be enabled until manually reset.

Abstract: A stand for an electric iron incorporates an automatic time delay safety switch arrangement which reduces the chances of fires being started by an unattended iron and serves to save a substantial amount of electric energy by cutting off the current to the iron when it is left turned-on but unattended. The stand includes a hinged, spring biased platform of insulating material for supporting an electric iron during non-use periods. Placement of the iron on the platform causes the platform to pivot closing a normally open switch. Closure of the switch energizes a standard electrically energized time delay relay mounted on the platform. After lapse of a predetermined time period, the time delay relay actuates a manually resettable electric relay from a first condition allowing the electric iron to be energized from a power supply socket on the platform to a second latched condition whereby the iron is deenergized.
