Automatic device for controlling the supply of fuel to a heater

An automatic fuel supplying device for use in a heater, which comprises:

• a body member having a cap and a support plate disposed between said body member and said cap, said support plate having first and second apertures,
• first and second push rods passed through said first and second apertures, said first and second push rods being inserted into said first and second magnetic units at one end thereof,
• first and second on/off switches disposed at the other end of said first and second push rods for being operatively associated with first and second drain holes disposed in the bottom surface said body member, and
• a fuel storage tank operatively associated with said body member through first and second fuel conduits, whereby, upon the operation of the electric source, the magnetic units are energized causing the pushing rods to fixedly engage with first and second cylinders of the magnetic units and the on/off switches to automatically open, thereby maintaining the fuel supplying action, and upon the sensing of a higher room temperature than a predetermined temperature of a thermostat connected to the second magnet unit, the electric source is disconnected and the second magnetic unit is no longer energized causing the pushing rod to disengage with the second cylinder and the second switch to automatically close, thereby stopping the fuel supplying action so that the heating is reduced and also, when the electric source for the automatic device is at the off position, the magnetic units are no longer energized and the first and second on/off switches close so that the heater automatically puts out the fire.
