Flow of liquid from the boiler back into the reservoir is prevented by my arrangement of piping. Thus as the water is heated in the bottom of the boiler and is vaporized it is replaced by a rising column of cool water in the pipe 22. F low in the reverse direction is prevented because as the liquid is vaporized and driven off from the top of the boiler a continuous flow toward the boiler through the connections with the reservoir is maintained and the hot water will not flow down through the colder water in the pipe 22. By my arrangement of pipes, I form what may be termed a cold water seal for the connection between the reservoir and boiler. This is an important feature of my invention. If medicant from the boiler 11 were transmitted back through the connections into the reservoir stoppage of the connections and fouling of the reservoir would be apt to result. I have found that stoppage of the connections and fouling of the reservoir is particularly troublesome where av thick or gummy medicant, such as benzoin, is used in the boiler. A quantity of such a medicant is commonly placed in a relatively large volume of water so that with my device pure water is supplied to the reservoir and the medicant in the boiler cannot reach the reservoir or small connections. To further insure against the stoppage of the small connections between the boiler and reservoir I provide the upright receiver and connecting nipple 23 located substantially below the bottom of the boiler. The receiver pipe 22 is sufficiently large to insure against stoppage even when a gummy medicant reaches the upper portions thereof and by reason of my arrangement for maintaining upward flow in this pipe 22 the medicant is prevented from reaching the nipple 23 or small pipes connected thereto.

After use the boiler may be quickly and easily removed from the reservoir for cleaning. To break the connections where some liquid remains in the boiler and reservoir after use, the coupling 21 is merely elevated above the level of the liquid and the tubes 19 and 20 are then separated at said coupling. Now the hook 25 is placed in engagement with the upper edge of the reservoir 6 and the hook valves I promote safety in the operation of the device because where valves are provided there is danger that the operator may leave one closed with consequent failure of the apparatus to replenish the boiler and destruction of the heating element when the liquid in the boiler is exhausted. It will now be understood that the extension 27, heating unit 14, cap 24 and the tube 20 may be removed from the boiler to facilitate the cleansing operation or removal of the residue from the medicant.

Having described my invention what I claim is new and desire to protect by Letters Patent is:

1. A portable vaporizer comprising a reservoir open at its top, an open boiler of relatively small size having its bottom projecting below said reservoir, connections for delivering liquid from said reservoir to said boiler, said connections including a rising member communicating at its upper end" with the boiler below the reservoir, and means for heating said boiler to vaporize the contents thereof, said connections being arranged to allow how by gravity from said reservoir to said boiler and to maintain the liquid in said boiler at substantially the same level as that in said reservoir.

2. A vaporizer comprising a reservoir, a boiler supported upon said reservoir, an upright unheated receiver for liquid communieating with said boiler at its upper end, connections adapted to deliver'liquid from the reservoir to said receiver, said connections having passages therethrough of smaller size than the passage through said receiver, and means for heating the contents of said boiler to vaporize the same, said connect-ions being arranged to maintain the liquid in said boiler at substantially the same level as that in said reservoir.

3. The vaporizer specified in claim 2 in which said receiver projects downward from the bottom of said boiler and said connection communicates with said receiver at a point removed from the boiler.

4:. A portable vaporizer comprising, a reservoir open at its top, a boiler supported upon said reservoir, means for heating the contents of said boiler to vaporize the same and connections arranged to allow flow by I gravity from said reservoir to said boiler comprising, at least two flexible sections normally joined by a rigid coupling and adapted to be separated at said coupling, said sections severally communicating with the reservoir and boiler, and means for supporting the free ends of said sections upon the reservoir and boiler above the level of liquid therein when separated at said coupling.

9 5. A vaporlzer for medicants and water comprising a reservoir for water, a boiler for water and medicants, connections adapted to deliver water from said reservoir to said boiler, means for heating the contents of said boiler to vaporize the same and a cold WILLIAM (J. KOCH.
