ELECTRICAL VAPORI ZER Original Filed Aug. 19, 1927 INYEXTCR 0 -W ATTORNEY Patented May 14, 1935 ELECTRICAL VAPORIZEB Joseph Robinson, New York, N. in

Application August 19, 1927, Serial No. 214,046 Renewed April 7, 1933 5 Claims.

My invention relates to improvements in electrical Vaporizers of the hand type for individual use in generating vapors for inhalation in the treatment of head colds and other head afflictions.

In my co-pending application, Serial No. 188,559, filed May 3rd, 1927, now Patent 1,775,947, issued Sept. 16, 1930, for Electric Vaporizers, I show an instrument of this character, and the object of my present invention is to adapt the vaporizer to the container in which the compound to be vaporized is marketed.

In the drawing Figure 1 is a sectional side elevation of my improvement showing it applied to the bottle or jar in which-one of the standard compounds is marketed;

Figure 2 is a bottom view of the plate I4, and

Figure 3 is a view of a modification of my improvement.

My invention comprises a sleeve or cap 5 in which a hollow body 6 is mounted so that it may slide up and down in the sleeve The lower end of the body is turned outward at l to prevent the body being lifted out of the sleeve. The body is made of any suitable material and shape, but preferably of metal and to the general conformation shown. On the upper end of the body I mount a perforated nozzle 8 adapted to fit the nasal passage. The nozzle is removably set over the upper end or neck 9 of the body. Within the body and extending through a wall thereof, I provide a tube or housing I0 within which a suitable resistance coil is mounted. The coil is of course insulated with respect to the tube 10 and is preferably covered with a suitable non heat conducting material except as to its lower or exposed end I I. Over the lower end of the coil I mount a cover or cap l2 which is threaded to or pressed over the tube l 0. The tube is positioned laterally within the body 6 by the plate 14 which is pressed into the lower end of the body or otherwise secured therein. The plate is perforated at IE to permit the vapors generated to be drawn through it. A shoulder IS on the tube is drawn into rigid engagement with the body 6 by a suitable switch 11 threaded to the tube. An ordinary electric cord I8 is connected through the switch to the resistance coil II. The compound to be vaporized is carried in the jar or container I8, the same being the jar in which the compound is marketed and to it the sleeve 5 is threaded.

In operation, my improved vaporizer is mounted on the jar It in the manner just described, and the body 6 is moved up or down in the sleeve 5 to set the cap 12 into the compound, preferably about half the depth of the cap. The current is then turned on through the switch I! and quickly brings the cap l2 to a temperature such as will vaporize the compound that is immediately adjacent to and in contact with the cap. The vapors thus generated are, on inhalation, drawn up 5 through the chamber A of the body 6 and through the nozzle 8. During the act of inhalation a current of air enters the container l8 through the recess or groove 20 formed in a wall of the body, and thence up through the openings l5 of the 10 plate ll to the nozzle 8. The chamber A is heated by the resistance coil II warming the vertical portion of the tube 10. The current of air mentioned is therefore heated in this chamber, and the vapors are delivered to the afliicted meml5 branes at an eflective temperature. By turning the switch I! on and off during the use of my invention, the vapors can be generated in the volume and at the temperature preferred.

By shoving the body 6 downward in the sleeve 20 5 and thence upwardly to the limit of its upward movement, the cap 12 may be dipped into the compound. This operation will leave the cap coated with a film of compound which will be quickly vaporized when the electric current is 25 turned on. This arrangement may be said to constitute means for delivering the compound from the container 18 to the heating element or hot-spot ll.

The resistance coil ll may be made in any de- 30 sired form, either such as shown in my above co-pending application, or my other co-pending application Serial No. 194,437, filed May 26th, 1927, for Electrical Vaporizers. Or the lower end of the coil ll may terminate in a self contained 5 heating element or hot-spot such as shown in my co-pending application Serial No. 212,111, filed August 10th, 1927, for Electrical Vaporizers.

The modification of my invention shown in Figure 3 consists of a handle 2| and a heating element or tube 22 such as shown and described in my co-pending application first above mentioned. The tube 22 is provided with indentations or cups 23 preferably near its upper end.

A sleeve or barrel 24 is dropped over the heating 45 element 22 with the cap or stock 25 resting on the upper end of the heating element. The cap is provided with a plurality of perforations 26.

A nozzle 21 sets in the upper end of the barrel 24 and has a groove 28 through which a current of 50 air, under certain conditions, enters the barrel on inhalation.

In operation the heating element is dipped into the compound to be vaporized, preferably when the element is hot. The compound fills the cav- 55 ities 23 so that on extraction oi the heating element, some of the compound adheres to it causing vapors to rise therefrom. The barrel M is then dropped over the heating element and the vapors are on inhalation drawn up through the nozzle 21. By closing the holes 26 in the cap 25 the compound may be placed in the chamber or barrel 24 at a point above the cap. When thus placed the compound will be vaporized by contact of the hot upper end of the heating element '22 with the thin cap 2|.

What I claim is:

l. A device for generating vapors for inhalation, comprising in combination, a container for containing the compound to be vaporized, a heating element extending from above the compound into the latter, means for mounting the heating element on said container including means for adjusting the element in relation to thebottom of the container, and nozzle means through which the vapors generated are drawn.

2. A device for generating vapors for inhalation, comprising in combination, a container for containing the compound to be vaporized, a hollow body adjustably secured on said container and having on one end a nozzle for application to the nasal passage, and a heating element carried by said body and adjustable thereby relatively to the container whereby to generate vapors to be grawn through said body and nozzle on inhala- 3. A device for generating vapors for inhalation, comprising in combination, a container tor containing the compound to be vaporized, including a hollow body, means for heating said compound to generate vapors and adjustable reatively to said body, and a nozzle through which said vapors and a draught of air are drawn upwardly through said body, said current of air being heated as it passes through the body.

4. A device for generating vapors for inhalation, comprising in combination, a container for containing the compound to be vaporized, an electrical heating element adjustably supported on said container and-adapted to be dipped into said compound from above the latter, and means through which the vapors generated are drawn on inhalation.

5. A treatment appliance of the class described comprising a hollow body, a heating member movable into the body and suspended in spaced relation to the same, a medicament heating surface in said body with which the heating member is adapted to cooperate to transmit its heat to the medicament contacting with said surface, and means for conveying the heated vapors to the part to be treated.
