It is a fact well known that the air very often becomes abnormally dry and therefore unhealthy in chambers heated by means of heat-radiators.

ing the percent of water in the airof the chamber is to provide evaporating receptacles on the heat-radiators. The evaporating receptacles hitherto generally used and consisting of earthenware suffer, however, from many inconveniences. It is diiiicult to keep them' clean, rust is formed On'their faces resting against theheat-radiators, they become readily mouldy and it often happens that water drips on floors and carpets. All these inconveniences are overcome by the present invention as the same renders possible the use of receptacles made of a nonporous material as hardened glass, sheetmetal and the like. The invention is mainly 2o characterized by the fact ythat a preferably Y cylindrical tube or the like made of a porous material is located in the receptacle, the upper end of the said tube preferably extending beyond the upper edge of the receptacle. The said tube is adapted to suck up the liquid and thereby facilitate the evaporation of same.

One embodiment of the invention is illustrated in the accompanying drawings, where Figure 1 is a side view, partly in section, of the receptacle, and

Figure 2 is a section on the line 2 to 2 in Figure 1.

According to the invention the receptacle 1 is made from hardened glass and comprises a cylindrical tube 2 of earthenware or another suitable porous material. In order that the tube may offer the largest possible evaporating surface it may be provided at 40 its top, above the water level in the receptacle, with projections or the like, or it may be plaited, or corrugated. In the shown embodiment the tube 2 has at the top on its outside, ring-shaped flanges 4 and on its inside it is lightly corrugated. One of the fianges The best manner of increasy 4 rests against the inside of the receptacle 1 and supports the tube laterally. Further, the upper end of the tube is flared or formed as a funnel 5 which facilitates the pouring in of the liquidl and, simultaneously, offers alarge evaporating surface. y

Thesaid arrangement is especially adapted to be used in receptacles made of transparent or semi-transparent material such as glass, in order that one may be able toperceiveeasily the level of the liquid, which has been very difficult in the receptacles of earthenware hitherto used, and lfor this reason the said receptacles have not always been filled up in due time. The tube Vmay be plaited or corrugated either transversally or longitudinally, and flanges running as screw- A threads may be substituted for the ringshaped flanges shown in the drawings. Evidently, the tube need not be cylindrical but it may have any suitable shape. The receptacle is adapted to be hung on the radiator in the ordinary manner by means of a hook not shown in the drawings.

lHaving now described my invention, what I claim as new and desire to secure by Letters Patent .isz

1. An evaporating device for heat radiay Y tors, comprising a receptacle for containing liquid, and a tubular diffusing element extending into the liquid, said element beingy formed of porous material and provided at its upper portion with a plurality of corrugations, at least one of said corrugations being adapted to contact with the inside surface of the receptacle for laterally Vsupporting said element and to maintain the element in spaced relation with the receptacle throughout its entire length.

2. An evaporating device for heat radiators, comprising a receptacle with open top for containing liquid and a diffusing tube of porous material open at both its ends and extending into lthe receptacle; said tube be- Ving provided at its upper portion with a plurality of corrugations, at least one of said corrugations being adapted to Contact with the inside surface of the receptacle for laterally supporting the tube and to maintain the element in spaced relation With the receptacle throughout its entire length; said tube having its mouth flared to form a funnel and for the purpose of increasing the evaporating surface.

In Witness whereof, I have hereunto signed my name.
