Oil burner comprising safeguard mechanism against power stoppage

An oil burner having a safeguard feature against interruption of electric power, said burning comprising:

• a vaporization and ignition means for vaporizing liquid fuel supplied thereto, for forming a combustible gas from vaporized fuel and air supplied thereto and for igniting said combustible gas;
• a liquid fuel supply pipe and an air supply pipe connected to said vaporization and ignition means, said fuel supply pipe being connected through said air supply pipe to said vaporization and ignition means, said air supply pipe being downwardly sloped between the portion thereof connected with said fuel supply pipe and the end portion thereof connected to said vaporization and ignition means;
• circuit means for connecting said burner to a supply of electric power;
• means for changing the flow rate of fuel supplied to said fuel supply pipe, said means for changing being connected to said fuel supply pipe;
• means actuated by said means for changing the flow rate of fuel, for applying suction to said air supply pipe to aid in extinguishing fire upon interruption of a supply of electric current to said burner;
• solenoid valve means connected to said fuel supply pipe and to said circuit means for stopping the flow of fuel therethrough upon interruption of a supply of electric current to said burner;
• air damper means for controlling the flow of air to said air supply pipe;
• solenoid means connected to said air damper means for reducing air flow through said damper mean upon connection of a supply of electric current to said solenoid means and for increasing air flow through said damper means upon interruption of a supply of electrical current to said solenoid means;
• and
• air flow means connected to said air damper means and to said circuit means for supplying a flow of air through said air supply pipe to said vaporization and ignition means;
• and
• weight means operatively connected to said air flow means for causing said air flow means to continue to rotate due to inertia force upon interruption of a supply of electric current to said burner;
• whereby upon interruption of a supply of electric current, said solenoid valve means closes to stop the flow of fuel and said damper means opens to admit a continued flow of air to said vaporization and ignition means to complete combustion of fuel introduced prior to said interruption.
