T0 all wwm z't may 'concem:

Be it known that we, Encan M. Somme and WILLIAM H. COSIELLO, both citizens of the United States, and residents of Chicago, in the county of Gook and State of Illinois, and of Milwaukee in the county of Milwaukee and State of Wisconsin, respectively, have invented new and useful Im rovements in Humidifiers, of which the f0 owing is a description, reference being had to the accompanying drawings, which are a part of this specification.

Th1s invention relates to humidifiers suitable for use in show cases and show windws where cigars or other articles requiring a moist atmosphere are displayed, or for use in dwellings, auditoriums and the like, wherever it is desired to increase the humidity of the atmosphere.

The invention further has for its object to provide a humidifier comprisin a wick for conducting Water or other liqui With which it is desired to charge the atmosphere and means for heating the wick to facilitate the evaporation of the water.

Another object of the invention is to uti]ize an incandescent -electric lamp as the heating means in such a humidifier and to so arrange and combine the parts as to produce a neat and attractive appearance and a structure that is inexpensive.

With the above and other objects in view the invention consists in the humidifier as herein claimed and all equivalents.

Referring to the accom an ing drawings, in which like characters 0 re erence indicate the same parte in diflerent views,

Fig. 1 13 an elevation of a humidifier embodymg this invention;

Fig. 2 is a sectional view thereof;

Fig. 3 is a plan view, and

Fig. 4 is a plan view of the base.

In these drawings, 10 indicates a base consisting of a cylindrical body refarably mounted on suitable legs 11 and aving an open central upstand' tubular projection 12 so that the interior 0 the base around the projection forme a circular well for containing water or other Jiquid to be' evaporated. Preferably the upper part of the base is provided with a number of vertical slots 13, as shown, extnding to 'its edge, thus leaving a number of upstandin spaoed fingers to oonstitute the rim et t e base. Upon this rim of the base is seated a dome or cover 14 having a shouldered flange 15 to engage the base in the manner shown in Fig. 2. This dome or cover is also provided With openings 16 so that there is free access for the air to the interior. An incandescent electric light bulb 17 is threaded in a lamp socket 18, which is clamped to the inwardly turned flange 19 at the upper end of the tubular pro ection 12, higher than the lower ends of the slots 13 and therefore above the water level. A glass lobe 20 surrounds the lamp bulband resta 1n seats formed for it by notched arms 21 extending radially from the tubular rojection 12. Stretched over this spherica lobe 20 is a tubular wick 22, greferably of itted fabric, which extends own into the circular Well and. is preferably also stretched over a cylindrical spreader 23 of woven wire fabric.

In operation the humidifier is placed in a humidor, or wherever it is desired to impart moisture to the atmosphere, and the lamp is lighted. The wick serves t0 lift the Water or other liquid 'from the circular Well by ca illary attraction and conducts it to the sur ace of the globe 20, where it is exposed to ascending currents of air entering throu h the slots 13 and assing out through t e openings 16, the eat of the lamp serving to heat the Water in the wick and to induce the air currents referred to and thus facilitate the evaporation. Not only does the eva oration take place in this manner but the air Within the globe heated by the lamp passes out at the upper end of the device and air is drawn through the moistened wick to take its place, so that it becomes saturated with the moisture in passing through the wick and consequently adds to the efiectiveness of the operation.

The device is simple in its construction and inox nsive and leasing in its appearance, ma 'ng it suite le for use in display windows and show cases, and it is particularly attractive when combined with a flasher or automatic means for intermittently extinguishi the light. It also has the advantage of s owing the need for water when the supply is exhausted because the wick as seen t rough the 0 enings with the light behind it presents a iferent appean ance when dry.

It is obvious that where the illumination provided by the incandescent lamp is not esird, an electrical heating element may 'What we claim as new and desire to secure byLetters Patent is:

1. A humidifier comprising a liquid container, a suitably mounted incandescent lamp, a globe surrounding the lamp, and a wick surrounding the globe and extending into th liquid container;

-2. In a humidifier, a liquid receptaclehav ing a central projection, an incandescent lam mounted on the projection above' the liqu1d' level, a globe mounted on-the projection and surrounding the lamp, a wick surrounding'the globe, and means for spread ing theWick within the liquid receptacle.

3. In a humidifier, a base forming alquid remptacle with openings in its sides and a central projection extendng above the liquid level, an incandescent lamp mounted on the said projection, a globe mounted on the projection and surrounding the lamp, and a wick stretched over the globe and eX- tending-into the liquid receptacle.

4. A humidifier comprising a base having slotted edges and forming a liquid receptacle with a central projection extending above the liquid level, au incandescent lamp mounted on the said projection, a globe surrounding the lamp and mounted on the projection, a wick surounding the globe and extending Within the liquid receptacle, a wire screen forming a spreader for the Wick within the liquid receptacle, and a cover for the base provided with openmgs. V

5. .A humidifier comprising abasehavig slotted edgcs and forming a liquid receptacle with a central projection extendin above the liquid level, a lamp socket secure to said projection, an incandescent lamp mounted therein, a globe mounted on the projection and surrounding thelamp with openings at its top and bottom .for the Passage of air, a wick surrounding the globe and extending into the liquid receptacle, and a cover for the base provided with openmgs. v

6. A humidifier eomprising a liquid re- .ceptade, a suitably mounted incandescent lamp, a globe surrounding the lamp and provided with openings at its top and bottom for the passage of air, and a wick surrounding the lobe and extending into the liquid receptac e whereby the upwardcurrent of air through the globe induced by the heatof the lamp Will bedrawn through the wick.
