ELECTRI C VAPORIZER Filed Nov. 1, 1946 2 Sheets-Sheet 2 [N1 ENTOR.

JOJPH Poem/501v BY MAM ATTORNEY Patented Feb. 22, 1949 were STATES QATENT rr cle' 3 Claims.

This invention relates to electric Vaporizers of the hand type for generating hot medicated vapors for inhalation. Among the objects are to simplify and improve such Vaporizers and reduce their cost of manufacture. In the accompanying drawings, which show my improvement approximately three times natural size,

Figure 1 is a vertical section through my invention;

Figure 2 is a top view of the heater B with the mica disc removed;

Figure 3 is a bottom view of the heater with the contact screws l9 and 2l removed, and

Figure 4 is a top view of the base A with the heater B and cover E removed, and showing the lower portion of the container D in section.

Referring to the drawings: The base A is made of any desired material and includes a vertically disposed cylindrical shank 5, preferably of less diameter than the base proper. The shank is provided at its top with an opening 6 to receive parts of the disc shaped heater B, and at its bottom with a suitable opening I, Figure l, to removably receive a conventional electric plug 8 having a cord 9, the openings 6 and I being separated by the wall l0. Each of the terminals II has a contact head 12, prefer-ably thin and fiat, and extends through the wall in into sliding engagement with the contact bushings M of the plug 8 as shown. The heater B comprises a ceramic base l having ways It in the top of which a resistance coil C is mounted, the end I! of the coil being anchored, through the opening l8 centrally arranged in the heater, to the contact screw [9 and the other end being anchored to the contact screw 2|, these screws having permanent contact with the heads l2 of the terminals I I. Suitable resilient means 22 lie between the nuts 23 of the screws and heads l2 to assure electric contact between these parts in the unlikely event of separation of the heater B from its annular seat 24 on the top of the shank 5 of the base A. Alignment of the screws and the heads I2 is assured by interlock of the lug 25, Figure 3, formed on the underside of the heater base I5, with the slot 26, Figure 4, in the top of the shank 5 and by'the aluminum container D. The container is turned back on itself to form the cup 21 which receives the substance to be vaporized. Below the cup the container is provided with a skirt 28 which embraces the heater B and. fits tightly over the shank 5 of the base A. The lower edge 29 of the skirt is turned in over the shoulder 30 on the shank into the annular groove 34 formed in the shank, firmly locking the base A and the heater B together with the parts in proper assembly, Figure 1. A mica disc 32 covers the coil C and insulates it from the bottom of the cup 2'! by which it is engaged. The mica disc is pressed tightly into the top of the heater base l5 to retain the coil in its ways It and protect it when handling the heater and for convenience in assembling the parts. The shank 5 of the base A is slightly enlarged in diameter at 33 to bulge the bottom portion of the skirt or sleeve 28 as it is moved to the assembled position, Figure 1. The bulge is upwardly tapered and serves to impinge the bottom of the cover E to prevent the cover from rattling on the container and from being accidentally dislodged therefrom. The cap or cover E, preferably a plastic molding, includes the hollow nasal part 34 for directing the vapors to the nasal passage. It embraces and insulates the container D and fits loosely thereon except as noted, the loose fit facilitating low cost manufacture. A plurality of vertically arranged serrations 35, Figure 1, are formed around the inner wall of the cover E and serve, on inhalation, to admit currentsof air to the cup 21. These air currents contact the hot adjacent walls of the container D as they move upward therealong and are heated in their journey. They turn downward at the top of the serrations 35 into the cup 21 where they pick up the hot medicated vapors and carry them, without appreciable temperature loss, upward through the nasal part 34 to the nasal passage.

Insertion of the plug 8 into the bottom of the base A, Figure 1, serves, of course, to close the electric circuit and light the heater B, while re-- moval of the plug breaks the circuit. Thus the plug and the terminals ll act as a switch for my improved vaporizer, enabling the user to conveniently maintain the medicated vapors at the temperatures desired by simply inserting and removing the plug at intervals. In addition to the tight fit of the terminals H in their openings in the wall ill they are locked against upward movement in the base A by the container D through its interlock with the shoulder 30 of the base.

What I claim is:

1. An electric vaporizer comprising in combination, a base having an opening therein, a wall across said opening, terminal means extending through said wall, an electric plug removably engageable with said terminal means below said wall, said plug serving as a switch for opening and closing the electric circuit, a heater mounted on said base and provided with contact means having circuit engagement with said terminal means, a container housing said heater and a portion of said base, said container being anchored to said base to tie the parts in the assembled position which the container includes a cup for the sub@ stance to be vaporized and is provided also with a skirt, said base having an enlargement and a shoulder over which the skirt of said container is forced to swell the skirt and lock it to said base for the purpose described.
