lt is another object of this invention to provide a vaconjunction with the drawing in whic Fig. 1 is a Vertical section taken through the vaporizer showing a oating Valve and indicating by dotted lines the movement of said valve,

Fig. 2 is a top View, broken away in part,

Fig. 3 is a detailed View showing the oating valve in its highest position, and

Fig. 4 is a bottom View of an electrically nonconductive iioating valve and showing its supporting legs.

Referring to the ldrawing a vessel or jar 1, for example, a glass jar is provided with a dome 2, preferably molded or" plastic, secured by screw 3 to a sure 4, disposed between the base of of jar 1 in a vapor-tight relationship.

solution in jar 1. on entering well 1l does so with force suicient to raise oating valve 14, so filling up of well 11 is done in wall of well 11 is small.

Upon plugging the electrodes into an electrical circuit wall of well 11, as well How set up by the tortuous path which the solution must follow in passing from a point above valve 14 to the ori- Having described my invention, what I claim and desire to secure by Letters Patents is as follows:

sel for holding an aqueous electrolyte,

a molded dome of dielectric material disposed over said vessel in vaporsteam, and a metal plug comrnunicat` ing between said interior of the container well and the i11- terior of said dome, whereby heat from the dome-confined steam heats said plug thereby heating vaporizable medicant disposed in said container well.

2. A thermally controlled vaporizer medicated vapors comprising an upright vessel for holding an aqueous electrolyte, a plastic dome disposed over said vessel in vapor-tight manner and having a vertically disposed medicant container well therein, a cylindrical vertically disposed vaporization plastic well secured to said dome in vapor-tight relation and disposed in said electrolyte and having an orifice in its base for passage of electrolyte from said vessel into said well, heating rods secured to said dome and immersed in said electrolyte in said well for changing water into steam, and a disc valve having a plurality of legs oatably disposed in the bottom of said vaporization well intermediate the bottom of said electrodes and the orice disposed in the base of said well, whereby the ease of introducing electrolyte solution above the valve in said well is greater than that of forcing out said solution by steam formed in said vaporization well.

3. A thermally controlled electrically heated vaporizer for vaporizing medicated liquid comprising an upright vessel for holding an aqueous electrolyte, a dome of insulating dielectric material disposed over said vessel and having an upright container well integrally molded therein, a cylindrical vertically disposed vaporlzation Well of for dispersing plastic material secured to said dome in vapor-tight relation and disposed in said electrolyte and having an orijce in its base for passage of electrolyte from said vessel into the vaporization well, electrically heating rods secured to said dome and disposed vertically in said electrolyte in said vaporization well for changing water into steam, a metal plug communicating between the interior of the container well and the interior of said dome, a metal container disposed in said container well and upon said plug, and a displaceable valve disc having a plurality of spacer legs oatably disposed in said vaporization well intermediate the bottom of said electrodes and the oriice disposed in the base of said Well, whereby medicated liquid disposed in said container is continuously heated by said plug which in turn is heated by the steam confined in said dome and the ow of electrolyte solution into said vaporization well is continuous for continuous formation of steam without eiecting a back pressure upon the surface of the electrolyte located in the vaporization well'.
