i2 Claims.

In this specification, and the accompanying drawing, I shall describe and show preferred forms of my invention, and specincfally mention certain of its more important objects. 'i do not limit myselfvto the forms disclosed how-a ever, since various changes and adaptations may be made therein without departing from the essence of my invention as hereinafter claimed, and objects and advantages, other than those specically mentioned, are included Within its scope.

My invention relates to therapeutic apparatus that is adapted for transforming volatile liquid medicaments into vapors, or into mists of exceedingly fine particles; and for applying these vapors or mists to organic parts that are to be treated. The principal objects of my invention include; nrst, to provide an improved method for vaporizing liquid medicaments by means of small electric currents; second, to furnish apparatus that is particularly well adapted for applying freshly vaporized medicaments to various organic surfaces; third, to supply very simple and convenient apparatus for the aforesaid purposes; and, fourth, to accomplish the above stated objects by means of relatively inexpensive devices.

My objects are attained in the manner illustrated in the accompanying drawing, in which- Figure 1 is an elevation of a typical form of my invention, one of the parts being shown broken away in order the better to show the construction;

Figure 2 is an elevation in central section of what may be considered to be the generic form of the principal element of my invention;

Figure 3 is a central section in elevation of a specific form of the` principal element of my invention; and

Figure 4 is another modified form of the principal element of the invention, in elevation and central section.

Similar reference numerals refer to similar parts throughout the several views.

I have discovered that when volatile liquids in relatively small quantities are protected from rapid cooling, such as might occur by draughts, they may be vaporized by means of a hot lament in close proximity to the surface of the liquid. This principle is utilized in this invention, in the various forms in which it may be employed. I therefore provide a vaporizing vessel of suitable form for holding a relatively small supply of fluid at the bottom; and containing an electrical conducting filament slightly-above the bottom, so as to be close to the surface of, the liquid contained therein. The vessel itself, aside from embodying these features, may be of any form that best adapts it to the special use for which it is intended.

(Gl, 2id-m33) The simplest kind of vaporizing vessel for this purpose, which may be consideredas the generic form of the principal element of my invention, may take the shape of an open-mouth vase, similar to a short test tube, such as is shown at 5 in Fig. 2. This form of the invention is adapted for liberating vaporized medicaments or other vapors, directly into a room for lmpregnating the atmosphere thereof, as for fumigating purposes.

A. specinc form of vaporizing vessel is shown at 6 in Fig. 3. In this case the vessel is substantially closed, but is provided with an inlet orifice l near the bottom and above the surface of the liquid, and an outlet orifice e near the top and considerably spaced from the inlet orifice. The heated vapors naturally rise, and will tend to flow in a continuous stream .from the outlet orifice; and, in doing this, will draw air from the outside atmosphere into the vessel through the inlet orifice. In other Words, this form oi vessel operates by natural draught, caused by the rising of the heated vapors, according to well known laws of physics. To se cure e, continuous and sulilcient flow of vapors under natural draught, it is desirable to have the container relatively long vertically, and the two orices should be considerably spaced. The vessel around the outlet may be variously shaped, to accommodate itself to the special purposes for which it is to be used. Thus the form shown in Fig. 3 is adapted for applying medicated vapors to the inside of the ear, or to membranes deep in the throat, or for insertion lnto the nostrils.

A second specic form of vaporizing vessel is shown at 9 in Fig. 1. In this form the inlet orifice 10 is near the bottom as before. The outlet orice 1l is above it, but may be close thereto. The whole vessel, therefore, may be shorter than the form shown in Fig. 3. The vessels of Figs. 1 and 3 are intended for inhalation purposes, the vapors being withdrawn from the vessel into the mouth, by drawing in the breath.

A third specific form of vaporizing vessel is shown at 12 in Fig. 4. This form is similar to that shown in Fig. 1, but the inlet orifice 13, and the outlet orifice 14, communicate with exterior nozzles 15 and 16 respectively, the nozzles being adapted for being inserted ir. the end of rubber tubes. This form of the invention is adapted for what may be termed forced-draught operation,

the vapors being expelled from the vessel from time to time, by forcing air thereinto. Thus, a compressible rubber bulb 1'7 may be connected by 'a short length of tubing 18 to intake nozzle 15; and, similarly, a rubber tube 19 may be attached to outlet nozzle 16, and have a suitably shaped and proportioned'tube at its free extremity. The latter nozzle (not shown) may be made for this purpose.

of any desired shape and size for insertion into small passages, such as sinuses, and the iiexibility of tubing 19 facilitates treatment in this manner. Owing to the frequent necessity of requiring relatively long tubing at 19, natural draught cannot be depended upon, and forced circulation, by means of operating the rubber bulb 17, will be required.

Whatever form of vaporizing vessel is used contains an electrical conducting filament. 20, slightly spaced from the bottom, and below the inlet orifice. Thefilament is supported by conductors 21, passing through and sealed into the base of the vessel which is constructed in the form of a terminal plug adapted to be plugged into a co-operating terminal socket, such as the socket terminal of an ordinary ashlight or other battery-containing kit as shown in Fig. 1

Volatile liquids may be introduced into the vaporizing vessels through the outlet or inlet orices, and these orices preferably should be in the form of tubes extending into the vessel as illustrated, to prevent the escape of contained liquid when the vessel is tipped or inverted during manipulation. The amount of liquid in the vessels in no case should be greater than sufficient to reach to the lower end of the filament when the vessels are in their upright positions. Thus, the maximum liquid level should be as indicated by reference numeral 22.

I prefer to mount the vaporizing vessels upon uniform screw bases or plug terminals 23, similar to those employed in the well known type of electric light bulb, so that the vessels may be interchangeably used in suitable screw sockets, for establishing an electrical circuit through their filaments. One of the conductors 21 in each case,

may be soldered to the inner surface of the employ a portable source of electricity, such as an ordinary flashlight battery of the type indicated at 25. This may have a screw socket 26' at one end, into which the plug terminal of any desired type of vaporizing vessel is screwed. Such batteries are commonly supplied with suitable switch means, as the thumb-button indicated at 27.

Another method of operating the device would be by means of a socket and flexible electrical cord, connectedto a suitable low voltage source of electricity such as a storage battery.

Where it is desired to use an ordinary light circuit as the source of electricity, it usually will be necessary to reduce the voltage by means of a small transformer, or else to employ resistance in series with the filament. However, it is possible to use filaments adapted for the full voltage of ordinary light circuits, if they are made of material of relatively high resistance, and of relatively great mechanical strength.

As will be seen by referring to the drawing the electrical conductors 21, extend through the liquid to be volatilized, with portions thereof, including the filament 20,-located just above the level of the liquid and in close proximity thereto.

Thus, it is entirely feasible to reoaeoe As a result of this arrangement, when the circuit is completed through the conductors vand filament to cause them to become heated, the liquid surrounding the conductors, or one of them, will become volatilized immediately and a geyser or .fountain-like stream or streams of vapor will be projected upwardly from the filament-conductors into the vessel. Vol'atilization of the liquid in the manner stated is, therefore, practically instantaneous. The vapor will collect in the vessel from which it may be withdrawn by inhalation or otherwise as heretofore described. When the vessel becomes filled or partially. filled with vapor the current through the conductors is cut off, as by the switch 27, and further vaporization ceases so long as the switch is open. After the vapor has been removed from the vessellby inhalation or otherwise, the operation may be repeated and this may be done as often as the exigencies of the case may require.

Obviously my invention may be utilized in a.
