Description

Sept. 28, 1954 M. KATZMAN VAPORIZER HEATING ELEMENT Filed July 10, 1952 INVENTOR. Max Karl/77g W? A T TOR/VESS Patented Sept. 28, 1954 UNITED STA OFFICE 1 Claim.

This invention relates to Vaporizers and more particularly to heating elements used in conjunction therewith.

An object of this invention is to provide an economical, readily assembled vaporizer heating element.

Another object is to provide a ceramic cover for a vaporizer which will support the heating element and its accompanying parts.

Other objects of this invention will be apparent from the following description taken in connectionwith the drawing, in which Figure 1 is a front plan view of my device partly cut away to reveal detail parts thereof;

Figure 2 is a bottom view of the parts shown in Figure 3; and

Figure 3 is a sectional view taken on lines 33 of Figure 2.

Referring specifically to the drawings, a vaporizer container 5 has a threaded neck 6 at its upper end which is engaged by the cover holddown ring 1, to secure cover 8 in position with respect to the container 5. Between the neck 6 of the container 5 and cover 8, a ring washer 9 is positioned to provide a seal between these two members respectively. The cover 8 may be mold-- ed from ceramic material and has a spout Ill including a passage lEla in communication with the inside of the container 5, so that the vaporized medicant from the container 5 may discharge therethrough and into the atmosphere.

Additionally projecting from the cover 8 is bracket I! which functions to guide and support the electrical connector (not shown) used in conjunction with this apparatus. The cover 8 is provided with a pair of holes through which the heating element terminals l2 and [3 project.

These terminals are fashioned with rounded tops and threaded lower portions inset from their main body portion and are spaced from the upper side of top cover 8 by washers M which engage the terminals at their inset portion. The threaded segments of terminals l2 and I3 engage

heating electrodes

18 and 19 to support them and electrodes incasing member [6 in a manner hereinafter set forth.

Heating electrode incasing member I6 may be molded from ceramic or the like material and incorporates a T-shaped slot 20 efiectively surrounding the electrodes l8 and It on three sides. At the upper side of the points of the Tare passages 2i and 22 through which threaded ends of

terminals

12 and 13 project. The heating electrodes l8 and 19 are inverted L-shaped and are constructed from copper or any other electrically conductive material. The feet of the inverted L electrodes 18 and I9 engage th cross-member of the T slot 26 of incasing member I6 and have terminals l2 and i3 threaded thereinto. Thus it may be noted that the terminals 12 and I3 support the heating electrodes and their incasing member [6 from the cover 8. A Washer I1 and the ring washer 9 are situated between the cover 8 and the incasing member It.

The lower portion of member it has a passage 25 included therein to insure free flow of the medicant around the heating elements.

I have described what I believe to be the best embodiments of my invention. I do not wish, however, to be confined to the embodiments shown, but what I desire to cover by Letters Patent is set forth in the appended claim.

I claim:

In combination with a vaporizer housing having a threaded neck portion, a disc-shaped cover for said vaporizer housing, a hold-down ring adapted to engage said cover and be threaded on the neck portion of said vaporizer housing, a pair of terminals seated on said cover and projecting therethrough, inverted L-shaped heating electrodes threaded on said terminals, an elongated T-shaped incasing member surrounding said electrodes on three sides, the feet portion of the electrodes being nestled in the cross portion of the incasing member, said construction and arrangement being such that the incasing member is supported by said electrodes, and a passage in the lower end of said incasing member.
