Joseph Robinson, New York, N. Y. Application February 14, 1936, Serial No. 63,819

4 Claims.

This invention relates to Vaporizers of the individual hand type for producing medicated vapors in the treatment of head colds, catarrh, sinus infection, asthma, hay fever, etc., and has among its objects the simplification of this type of vaporizer and the provision of novel means for supporting the vaporizer in a generally upright position to avoid the necessity of emptying the instrument and wiping it dry after each use. Certain parts of the construction are generally like corresponding parts in my co-pending application Serial #44,236, filed October 9, 1935.

In the accompanying drawing Figure l is a vertical section through my improvement showing some of the parts in elevation;

Figure 2 is a side elevation of my improvement showing the use of the folding handle as a stand for supporting the vaporizer, and

Figure 3 is a side elevation of a modification of the handle by which a double stand is produced to hold the vaporizer in a more upright position.

My improvement includes a short hollow base A on the top of which is mounted.a heater B. The heater is tightly secured in place by a combination container and sleeve C which passes down over the heater and over the upper end of the base A. The container is firmly anchored to the base by turning the lower edge of the sleeve 0 over a suitable annular shoulder formed on the base for the purpose as at 5. In this way the cup 6 is drawn tightly against the upper insulated face of the heater B and the several parts are securely held in place. A hollow cover or cap D, having vertical serrations l which curve over the top of the cup 6, is mounted on the container and insulates the latter. Within the hollow base A I provide a terminal member 8 and secure it to the base by means of a screw 9 which also anchors the strand Ill of the usual electric cord E to this member. The terminal constantly engages the lower contact point H of the heater B. Diametrically opposite the terminal 8 I provide a quite stiff vertically extending resilient contact blade 12 which has a laterally projecting base I4 that is anchored to the inner wall of the base A by means of a screw l5 that also secures the strand N5 of the electric cord in place. The cord is knotted inside the base A to relieve the strands I0l6 of strains in service.

As a combination handle, stand and switch actuating, device for my improved vaporizer I provide a U shaped member F which is pivoted in one side of the base A as at I1. Diametrically opposite this pivot the member is provided with an inwardly turned portion l8 of substantial length which passes through and is pivoted in an opening provided for the purpose in the base A. To insulate this portion with respect to the blade I2 I mount over the portion a suitable insulating sleeve or cover 9. The handle is retained in the position shown in Figure 1 by a groove 20 in which the handle is resiliently held by the tension of the contact blade l2.

To convert the handle into a stand for the vaporizer it is rotated laterally with respect to the base A into the position shown in Figure 2. This position is predetermined by a groove 2|, leading in opposite directions from the pivots I'|-l8, into which the handle snaps when it reaches the position shown in Figure 2. This arrangement provides a simple and inexpensive stand for the vaporizer that eliminates the necessity of emptying the instrument and drying it in order to put it down after use or during use.

When it is desired to generate vapors with my improved vaporizer the medicament is placed in the cup 6 whereupon the handle F is gripped sufficiently to hold the contact blade l2 inwardly against the contact washer 22 of the heating element B. This lights the element. When the desired temperature for the vapors is reached the grip is released and the handle and the contact blade return to the normal position shown in Figure 1. The upper end of the cap D is then placed in the nasal passage and on inhalation air currents are drawn into the serrations I. These air currents travel upwardly into the chamber 23, being heated during the journey, where they collect the hot vapors and carry them into the nasal passages.

The modification shown in Figure 3 consists in providing an additional U shaped handle 24 which is pivoted on the inwardly extending horizontal portions of the handle F, these portions being lengthened sufiiciently to receive the additional handle. To form the stand shown in Figure 3 these handles are opened in opposite directions.

What I claim is:

1. A vaporizer of the character described, comprising in combination a base, a heater secured thereto, a container heated by the heater, and a switch for controlling the heater, said switch including an actuator handle pivotally connected with said base and adapted to be pivoted laterally to form a stand for supporting said vaporizer.

2. A vaporizer of the character described, comprising in combination a base, a heater secured thereto, a container seated on the heater, and a switch for lighting the heater, said switch including a two piece handle adapted to be spread apart laterally in opposite directions to form a stand for supporting said vaporizer.

3. A vaporizer of the character described, comprising in combination a base, a heater carried thereby, a container heated by said heater, a switch for controlling the heater, said switch including an adjustable handle adapted under pressure to close said switch, and means for retaining said handle inrthe adjusted position desired.

4. A vaporizer of the character described, comprising in combination a short hollow base, an electric cord secured to terminals within the base,

said base to form a stand for the vaporizer.
