Application Aam: 1o. 1936, serial No. 95,298 12 claims. (ci. 21a-_40) This invention relates to improvements in the points about the interior of the tubular electrode I5 I provide guides I8 of insulating material art of vaporizing medicaments and other mate which define the vertical path of movement of rials. `It is the primary object of the invention to the spherical float I2 and determine the mini I ' provide an improved device and method for -va porizing certain materials which are apt to co - agulate at the surface when vaporized between ordinary immersion type electrodes. It is my objective to provide for the evaporation of the l0 liquid almost entirely' in the surface stratum thereof, whereby the agitation and movement in cident to the evaporation will break up any mum spacing of such ñoat from the tubular elec trode l5. ‘ An insulated conductor I9 is connected with electrode I5, and the bridge conductor I0 and the electrode conductor I9 are both led to a con ventional electrical receptacle 20, to which an extension cord- may be applied to impress the usual lighting circuit of III! to I2II volts upon coagulation, and will also tend to prevent de'- . the electrodes I2 and I5. posits on the walls of the container, and will make 15 impossible the bridging of ‘solids upon electrodes which in `many devices short circuits the elec trodes and prevents the normal function of the device.l Other objects pertain to details of -construc 20 tion and will appear more fully from the followf ing disclosure. l In the drawings: Figure l is a view in axial section of a Vaporiz ing device embodying my invention. Figure 2 is a similar view showing a modified construction of the apparatus. - Figure 3 is a view in axial section showing a still further modified embodiment of the inven tion. . Figure 4 is aview in transverse section taken on the line 4--4 in Figure 3. Figure 5 is a plan view of the iioat used in the Figure 2 construction. Figure 6 shows, in plan, a modiñed embodiment 35 of float usable in the Figure 2 construction. Like parts are identified by the same reference l characters throughout the several views. The container 1 holds a body of vaporizable liquid such as those inhalants used in respiratory diseases. The level of the liquid in the con tainer will vary in use, and at the moment stands at the point indicated in Figure 1. The container has a discharge spout l for the vapors and a clo ß sure l which may be removed for the insertion of additional supplies of liquid. l Below the closure the mouth of the vessel is bridged by a conductor Il, from which depends a conductor I l which is preferably helically coiled u but has no particular resilience and serves merely to convey the current to a spherical float I2. Resting on the bottom of the container 1 is a tubularvelectrode I5 having slots >IB at frequent `intervals to permit free movement of the liquid u to the interior of the electrode. At three or more Since the greatest diameter of the float will be at or near the surface of the liquid, and since 15 this portion of the float will approach most close ly to the tubular electrode I5, it will be apparent ' that practically all of the current traversing the body of liquid in the container 'I will pass through such liquid in the stratum thereof substantially at the surface. The heating effect occasioned by the resistance of the liquid will therefore pro duce great agitation and ebullition in this sur face stratum in the evaporation of the liquid. The resulting movement of the liquid will pre vent any bridging of solids between the elec trodes such as might otherwise occasion short circuiting, and I have found devices employing this principle can be operated successfully in liquids of such density that they would speedily incrust and stop the operation of a conventional immersion type evaporator heater. In the construction shown in Figure 2 the con tainer 1I differs only in form from that already described. The conventional electrical recep tacle 2li is mounted on a member IIN which spans the mouth of the container immediately below the cover SII. In this construction both of the electrodes are floated, electrode IZB being mount 40 ed on a disk-like central float I2I, and electrode ISI being mounted on an annular concentric float I5I. The respective floats may be connected by the spacers 22, and the leads 23 and 2l may be used to connect the electrodes |20 and |50 respec 45 tively with the helically coiled and substantially non-resilient conductors III and III which are supplied with current from the receptacle 20. This gives an arrangement which is mechanically balanced so that insofar as the conductors III 50 and III are subject to tension they will not unduly tilt the compound ñoat which carries the electrodes. Like the device already described, the electrodes |20 and ISI will be uniformly spaced, and in this instance each. electrode is of 2 2,111,206 such slight vertical extent as to' assure the pas sage of substantially all oi' the current through dielectric means for guiding and positioning said iloat. the top stratum of the liquid only. the delivery through spout BII of the vapors there 5.
