AIR MOISTENING DEVICE Filed Sept. 30, 1932 Patented May 8, 1934 UNITED STATES PATENT OFFICE 4 Claims.

My invention relates to air moistening devices for homes, oiiices, factories and the like, and my main object is to provide a device of this kind which is in the form of a small and compact unit which can be used in conjunction with an electric lamp.

A further object of the invention is to design the novel moistening device for support by the conventional electric lamp or bulb, so as to receive heat therefrom.

A still further object of the invention is to construct the novel moistening device in the form of an annular chamber which receives a supply of Water and disseminates the same in the form of moisture.

Another object of the invention is to provide the novel moistening device with a small container for water, perfume or disinfecting liquid for the supply of the moistening device.

An additional object of the invention is to construct the novel moistening device of few and simple parts which are of a rugged and durable nature.

With the above objects in view and any others that may suggest themselves from the specification and claims to follow, a better understanding of the invention may be had by reference to the accompanying drawing, irwhich- Fig. l is a perspective View of the novel moistening device, showing its application;

Fig. 2 is a plan view of the device; and

Fig. 3 is a section on the line 3-3 of Fig. 2.

It is a familiar fact that heat promotes the formation and dissipation of moisture, and I have chosen the common electric lamp as a source and support for the attachment of my moistening device. Thus, by reference to the drawing, it is seen that the main portion of the device is a horizontally positioned hollow ring vor chamber 10. This chamber is of a size somewhat in excess of the conventional watt or 100 Watt lamp 11 used for household and factory illumination, and the chamber is intended to be disposed about the lower part of the lamp as shown in Fig. 1.

On the inside of the chamber 10 is applied an arch 12 of sheet metal, Whose legs 12a are secured to the chamber as indicated at 12b or otherwise secured to the same. The top of the arch is expanded to form a ring 12e which is of a size to fit over the narrower portion of the lamp 11 and thus secure a support for the chamber 11.

The chamber 11 is formed with a number of lateral outlet pipes 13 which communicate with the medial portions of external vertical tubes 14, these tubes being open at both sides.

(Cl. 21B-45) The chamber 11 also has a downwardly extending pipe 15 which is fitted into and descends through a cap 16 which is inwardly threaded to receive a small bottle 17. The pipe 15 extends down into the lower portion of the bottle and receives on the inside a wick 18 which may be reinforced if desired by an internal wire (not shown).

When the moistening device is to be used in a certain portion o1? a room, that lamp 11 which is located therein is unscrewed from its socket 11a and passed upwardly through the device to receive the ring 12C. The lamp is then screwed into the socket and the current turned on. The bottle 17 contains a lling of water, and when the chamber 10 has become heated by the burning lamp, the heat oi the chamber and that of the tube l5 will cause the water which is present in the latter by capillary attraction to rise into the chamber 10 and form into a vapor. This vapor issues laterally through the pipes 13 and escapes both in upward and downward directions through the tubes 14 by reason of the circulation caused in the atmosphere by the heat of the lamp. Thus, the chamber 10 continuously draws water from the bottle 17 and dissipates the same in the form of moisture into the surrounding atmosphere. I have found by experiment that a bottle containing but a few ounces of water will serve for several days, and it is an easy matter to simply unscrew the bottle 17 and refill it when necessary. Obviously, a perfume or disinfecting liquid may be substituted for the plain water where a fragrance or antiseptic medium is desired for the room atmosphere.

t will be evident that the air moistening device described above is a simple, compact and sturdy attachment for the lamp. It can be made from aluminum or other light metal for the most part in order not to impose any strain on the lamp. It does not place anything in the way of the light cast downwardly from the latter, so that the use of the latter for the purpose of light may not be impaired. The assembly of the bottle 17 is small and does not perceptibly interfere with the light cast by the lamp.

While I have illustrated and described the invention in the preferred form, it is evident that the same is capable of minor changes and renements, and it is my intention to include such changes and refinements as coming within the spirit and scope of the appended claims.

I claimt- 1. An air moistening device comprising an annular chamber adapted to be disposed about a 3. The structure of claim l, said liquid reservoir being removably attached to the feed tube.

4. The structure of claim l, said outlet means comprising tubes radially extended from the sides of the chamber, and branches of such tubes opening upwardly and downwardly.
