ABSTRACT OF THE DISCLOSURE SULFUR-MELTER APPARATUS HAVING SLOPING BOTTOM AND AUTOMATIC SHUTOFF THEREFOR An apparatus for melting powdered sulfur is disclosed. The apparatus comprises a covered hopper having a sloping expanded surface area bottom with a heating element directly thereunder and means for collecting and recovering the molten sulfur in communication therewith. The apparatus minimizes problems of sulfur bridging and is preferably portable. It finds preferred application supplying molten sulfur for the on- site preparation of concrete coatings, sealants and the like. A device for automatically shutting off a sulfur melter when its supply of sulfur is exhausted or when sulfur bridging has occurred is also disclosed. The shutoff uses a temperature value sensed at the top of the melter's sloping melter bottom and shuts the heat off when the sensed temperature exceeds a preset value related to sulfur's melting temperature. The device avoids jamming and maintenance problems inherent in the use of mechanical level controls in a powdered/molten sulfur environment.
