May 10, 1932. L.- A. COLLINS ELECTRIC VAFORIZER Filed June 28. 1930 aw/germe Juf, I /l/ Patented May 10, 1932 PATENT FFC LAWRENCE A. COLLINS, OF LONG BEACH, CALIFORNIA ELECTRIC VAPORIZER Application led June 28,

The invention relates to improvements in electric vaporizers adapted for use in producing medicinal vapors, and has for its primaryobject the provision ot' an improved construction of this character, capable of economical manufacture and highly eilicieut in use.

Another object ot the invention is the provision of an improved construction of this 1.0 character having specialA provisions for mounting the cover thereon to prevent breakage and cause return of any overflow liquid thereto.

Other objects will appear hereinafter.

The invention consists in the combinations and arrangements of parts hereinafter described and claimed.

The Ainvention Will be best understood by reference to the accompanying drawings forming a part of this specification, and in which y Fig. 1 is a top plan view of `a vaporizer embodying the invention;

Fig. 2 a section taken substantially on line 2-2 of Fig. l;

Fig. 3 a section taken substantially on line 3-3 of Fig. 1, with the electrodes removed; and

F ig. 4 a partial section taken substantially on line 4-4 of Fig. l with the electrodes removed.

The embodiment of the invention illustrated in the drawings comprises a suitable vessel or container 10, preferably made of glass,

porcelain or the like, and provided at its top with an outwardly and upwardly extending cup-shaped lip 11 as shown. The container 10 is provided with a removable cover member 12, which also preferably is 4o made of glass, porcelain or other insulating material. This cover member 12 is provided With a plurality of radially extending supporting lugs 13 adapted and arranged to rest Within the cup lip 11 and loosely support the cover member in place. The cover member is also provided with a central gas discharge spout-14 and the supporting lugs 13 provide entry iiow spaces so that any overflow bubbling from the spout 14; will be returned tothe interior of the container 10.

of said members becomes unduly heated in use.

The cover member 12 is also provided with a depending apron 15 projecting downwardly into the top of the container lO and forming therein a gas chamber. The apron l5 is provided with a number of lateral openings 16, so as to permit of free access and circulation of the medicinal tluid or the like in the container 10.

The cover member 12 is also provided with two diametrically arranged electrode openings 17 adapted and arranged to receive threaded metal studs 18 at the upper ends of hollow metal electrodes 19. Nuts 2O on the studs 18 serve to ysecure the electrodes .in place, rubber Washers Q1 being imposed as shown. Suitable caps 22 are threaded on the outer ends of the studs 18and serve as suitable means for connecting electric Wires 23 with said studs for supplying electric current to said electrodes.

1n use, the container is provided with a suitable medicinal solution, as indicated in Figs. 2 and 3, which is capable of emitting medicinal vapors upon the passage ofvali electric current. Electric current is then supplied through the Wires Q8. thus forming one of the electrodes 19 into an anode and the other into a cathode ot an electrolytic circuit-'l tion in the container 10 thus emits medicinal lvapors which are discharged through the 85 The passage ot the current through the solu? heat has a tendency to cause unequal expansions between the container and its cover, thereby breaking 'one or the other. This tendency to breakage is avoided by the loose mounting of the cover member, which will permit of free relative expansions or movements .between the cover and the conta-incr.

The construction disclosed constitutes a simple and effective one for the purpose, which is capable of economical manufacture and will be found to be highly efficient in use.

While I have illustrated and described the preferred form of construction for carrying my invention into effect, this is capable of variation and modification without departing from the spirit of the invention. I therefore do not wish to be limited to the precise details disclosed but desire to avail myself of such variations and modifications as fall within the scope of the appended claims.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent is:

l. A vaporizer comprising a container of insulating material, provided at the top with a cup-shaped lip; a cover of insulating material resting loosely in said lip and having an upwardly projecting central normally open discharge spout, said cover member being also provided with a depending apron form'- ing a gas chamber in the upper portion of said vided at its top with a cup-shaped lip; a cover having radially projecting lugs resting loose ly in said lip and also provided with an upwardly. projecting discharge spout, whereb 1 any overflow throuvh said spout will be coli lected by said cup-sliaped lip and returned to said container; electrodes arranged in said container to generate gases to be discharged through said spout; and means for supply ing electric current to said electrodes.

In witness whereof I have hereunto set my i hand this 21st day of June, 1930.
