  • rearward heating elementiiof the pair of heating elements lies in the lillustrative form of wax pot, directly underneath the-smaller compartment !3, so thatwax in this compartment will be heated rapidly. Further heating of wax in the smaller compartment 13 will take place due not only to the fact that the web 9 (which constitutes the front wall of this compartment) is heated by actual contactwith the thickened portion I of the bottom of the wax pot which houses the heating elements, but also due to the fact that the rear wall of the pot (which also comprises the rear wall of thissmaller compartment) and'als'o the sides of this compartment are'heated by direct conduction from the heating elements.
  • the smaller compartment is heated on all its sides and its bottom by'heating elements positioned directly beneath the smaller compartment and since it is narrow from front to back, "wax in itwill' melt quickly. Also due to the fact that the whole of the bottomv and sides of the wax pot including its front wall become directly heated by the elements 5, wax placed in the larger compartment. I5 will also be melted though more slowly thanthe wax in the smaller compartment i3, and can therefore flow into the latter through the opening H in the web S to replace wax used therefrom.
