Application February 18, 1936, Serial No. 64,475 Renewed August 16, 1939 4 Claims.

This invention relates to vaporizers of the individual hand type for use in generating vapors for direct inhalation in the treatment of head colds, catarrh, sinus infection, asthma, hay fever, and other afflictions of the respiratory organs. The invention is an improvement on the construction shown in my United States Letters Patent #2,197,840, granted Apr. 23, 1940, and among its objects are the reduction of manufacturing costs; the provision of simple and improved means for anchoring the switch blades of the vaporizer in place, and the provision of a combination container and sleeve in which the container, in one form of my improvement, is relatively shallow and may be used either as a container for the medication to be vaporized or as a support for a discardable pellet or wafer that contains the medicatlon.

In the drawing,

Figure 1 is a vertical section through my improvement, some of the parts being shown in elevation;

Figure 2 is a plan view of the construction shown in Figure 1 with the cap F removed;

Figure 3 is a sectional plan view on approximately the line 33 of Figure 1;

Figure 4 is a sectional detail of the bottom of the base A of my improvement showing a portion of the blade l6, and one of the terminals 2| in front elevation;

Figure 5 is a side or edge view of the contact blade I! showing the curved formation of the lower end l-8 of the blades before they are put in place.

My improvement includes an elongated hollow base A, which is tapered practically throughout its length. In its lower portion the base is provided with inwardly projecting lugs or shoulders I, Figure 3, which are reinforced by upwardly inclined brackets 8. Between these brackets the lugs are provided with suitable vertically arranged rectangular sockets or bearings 9 of proper size and depth, as shown. The usual electric cord B- extends into the base A through the bottom thereof, and is knotted at ill to free its terminals ll of undue strains. The terminals are suitably anchored to the ends of the strands 12 of the cord and have flat turned back portions l4, and feet or lugs I5 that extend :at substantially a right angle to a vertical plane. The terminals are in- 'serted in the sockets 9 and are firmly anchored in place by vertically extending resilient switch blades l6-I1. The lower end of each of these blades is normally curved, at I8, Figure 5, the curve being straightened out as the blades are forced down into the sockets or bearings 9. In this way a considerable amount of spring tension and frictiongare produced between the terminals, the blades and the rear wall of the openings. The friction or tension is of such extent as to firmly 5' but removably secure the blades and the terminals in the assembled position shown in Figure 1, and to prevent the blades moving laterally or vertically unduly in the bearings '9. To further assure proper lateral positioning of the blades I provide for the blade I! a vertically extending groove L9 in the wall of the base A and turn the upper end 20 of the blade into this groove, and l in the case of the blade I6 I turn its upper end 21 abruptly inwardly across the vertical center line of the base A and perforate it on this center line to receive the lower portion 22 of the heater C shown in my aforsaid co-pending application. In the assembled position shown in Figure 1 the projection 2| of the blade i6 is vertically compressed or deflected to assure constant contact between it and the heater C. It will be noted that the blades I'6ll lie closely along the inner walls of the base A, and that the blade l6 bears against the base at 23 to form a support for the blade.

The heater C rests on top of the base A and is anchored to it by the two piece combination sleeve and receptacle or container D which fits tightly over the upper end of the base and is firmly secured thereon, in liquid tight relation thereto, by crimping or turning the lower edge 24 of the sleeve over a shoulder formed for the purpose on the base A. The upper end 25 of the sleeve is turned over a shallow receptacle 26, the connection between the receptacle and the sleeve bein liquid tight, and the bottom of the receptacle being drawn tightly against the upper insulated face of the heater C by the crimping operation described. The receptacle 26 directly receives a 0 medication, when desired, and serves as a support for a medicated, or medicine filled, pellet E of any suitable construction. I show this pellet in the form of a small metallic container having a cover 21 centrally perforated as shown. A suitable cover or cap F, having a mixing chamber 23, sits loosely down over the combination receptacle and sleeve D, insulates against the'heat of the sleeve, and is provided with a plurality of vertically extending serrations 29 which at their upper end turn inwardly over the top of the pellet E, similar to the arrangement shown in my aforesaid co-pending application. The construction construction forms, at the bottom of the mixing chamber 28, a shoulder that extends over the pellet and serves to position the cover F on the vaporizer and to retain the pellet in place.

In assembling my invention the cord B is inserted in the base through the opening in the latter, the terminals H-l4 being small enough to pass throughthe opening in the bottom of the base. The cord is shoved entirely through the base and is then knotted whereupon it is drawn back to the position shown in Figure 1. The switch button is then inserted, its head 36 oocupying the groove I9. The blades IBI1 are then pressed into place, after which the heater C is mounted on the upper end of the base A with its lower portion 22 passing through and engaging the inwardly turned angularly disposed projection 2|. The inclination of this projection holdsthe heater oh its seat on the base A until the com bination receptacle and sleeve D is set over the heater, and over the upper end of the base A, and is drawn tightly down into place by crimping its lower edge 24 over a shoulder on the base, as hereinbefore described. This operation serves to draw the sleeve and the container 26, firmly into place, straightening out the projection 21 of the blade 18 to the horizontal position shown in Figure 1, and pressing the blade tightly in itsgroove in the lug I.

When it is desired to vaporize a medicament I with the preferred form of my improvement, the medicament is either placed in the'container or the medicated pellet or wafer E, which is preferably packaged in quantities, is placed in the container or receptacle 26. The switch button 35 is then pressed in, which throws the upper end .of

,, the blade i7 against the contact washer 36 of the heater Cand lights the heater, the thin walls of the pellet E expediting the vaporization of the medicament. When vapors are produced, the tip 3'8 of the cover F is placed in the nasal passage, and on inhalation currents of air are drawn into the vents or ways 29 and are heated as they travel up along the hot walls of the sleeve D into the hollow chamber 28 of the cover F. Here the heated currents of air meet and lift the vapors, while hot, into the nasal passage. What I claim is:

1. An electrical vaporizer comprising in combination, an elongated hollow base provided with .a horizontally arranged seat on its upper portion, a pair of vertically arranged sockets or bearings formed on the interior of said base adjacent to the bottom thereof, a heater mounted on said seat and positioned horizontally thereby, a receptacle for a substance to be vaporized, said receptacle being fitted tightly to the upper end of said hollow base in retaining relation to said heater and in liquid tight relation to said base, a nasal part set over said receptacle and insulating the same and serving to direct the vapors to the nasal passage, an electric cord extending into said base from the lower end thereof, and a pair manually pressed against the heater to close the circuit. I I y g I a 2. An electric'vaporizer such v as-described in claim 1 in which'the terminals of the electric cord are also mounted in said vertical sockets,
