Abstract
Ice melting apparatus having an elongated vertically disposed body member with a melting head at the lower end which is heated by a flame to melt the ice. The heat is concentrated near or within the melting head and exhaust gases are expelled through an exhaust passage. The generated heat melts a hole in the ice conforming generally to the configuration of the melting head which in most cases is circular.
