The invention relates to radiators for steam, hot water, or other heating systems employing humidifying devices. It has for one of its main objects to provide a humidifying device, formed integrally with the radiator sections, over which a relatively shallow stream of water will ow to be evaporated so as to impart water vapor to the surrounding air.

Another object is to provide means whereby the water or condensate in the radiator sections may be trapped and conveyed to the humidifying devices. A further object is to so construct the devices that they may be incorporated in radiators oi various designs andtypes,regardless of the manner in which they are assembled. A still further object is to provide means for regulating the iiow of the water through the humidifying devices. Additional objects are to provide humidifying devices and condensate traps and chambers in connection with radiator sections without altering their general contour or appearances, and without adding greatly to their cost. These and various other objects and advantages will be readily understood from the following description and from the accompanying drawings of certain preferred embodiments of the invention in which, however, modifications may be made without departing from the scope of the appended claims. In the drawings Fig. 1 is a side elevation of the upper part of a radiator section, shown partly in cross section to disclose the humidifying device contained therein;

Fig. 2 is a top View of same, also partly in cross section;

Fig. 3 is an end view of several radiator seotions connected together, one or" which is shown partly in cross section;

Figs. 4, 5 and 6 are top views showing medincations of the huinidifying device;

Fig. 7 is a cross sectional side elevation taken on line '7-7 in Fig. e;

Fig. 8 is a fragmental, side elevation of the upper part of a radiator section, shown in cross section to disclose the condensate trap contained therein;

Fig. 9 is a fragniental, side elevation of the upper part of a radiator section shown in cross section to disclose the condensate chamber contained therein;

Fig. 10 is a cross sectional side elevation of a plurality of sections showing one method for trapping the condensate and delivering it to the humidifying devices; and

Fig. 11 is a fragmental, cross sectional View illlstrating a slightly diiierent means for doing Referring iirst to Figs. 1, 2 and 3, which illustrate the ordinary type of radiator sections l() which are connected side by side as shown in Fig. 3, the humidifying device or waterV well 11 is shown located within the section and near its top. This is the preferred position, but the well may be located elsewhere in the section and still produce the desired result. The well is cast integrally with the section so as to be completely separated from the steam space 12. The bottom 13 of the well is substantially level but provided with a central, upwardly-extending bailie 14. An inlet 15 and an outlet 16 are provided in the sides of the well, and orices 17 are provided in the roof of the well; through these the water vapor escapes.

The water wells are connectedtogether byshort nipples 18, as shown in Fig. 3. To assure a shallow flow of water through the wells, a device of the type shown at 19 is employed. It consists of a receptacle 20 into which water iows from a supply pipe 21. An overiiow pipe 22 is also connected with the receptacle. The upper end of the overflow pipe extends above the bottom of the receptacle, as shown at 23, to insure a shallow flow of water through the outlet 24 which leads to the water well 11 in the iirst section; any surplus water being drained through the overflow pipe.

The proper depth of water is such that it will not overflow the baiiles le while flowing through the wells. Asuitable valve is connected to the pipe 21 to regulate the flow of water and a waste pipe 25 drains off whatever water may remain unvaporized after passing through the water wells. In practice, the now of water is so regulated that practically all of it will be vaporized while passing through the water wells.

Figs. 4, 5, 6 and 7 illustrate the type of radiator section which is connected end to end instead of side by side. In this case the entire top of each section is employed as a humidifying device. The water to be vaporized enters through inlet 26, iiows between baies 27 and is discharged through outlet 28. The water vapor escapes through orices 29. In Fig. 6 a modification is shown wherein the water flows in opposite directions as indicated bythearrowsBG and 31. In this case the partition 32 extends to the top of the humidifying d evice and each section may be said to contain two such devices.

instead of using water direct from the ordinary water supply, the water for the humidifying devices may be taken from the radiator in the case of hot Water systems; and, in the case of systems using steam or vapor, a part of the condensate may be trapped and conveyed to the humidifying devices. In either case evaporation is facilitated by the higher temperature of the water, and, as the water is free from impurities no sediment is deposited in the water wells.

In Fig. 8 a section A is shown in which a trough 33 is cast below the inlet 34. This trough extends across the steam spacel2fandc0nveys to the adjoining section whatever condensate from the steam may be caught therein. In Fig. 9 a section B is shown in which partitions 35 are cast across the steam space so as tol form a chamber 36 into which the condensate will flow from the trough in the adjoining section. An outlet 37is provided in this chamber.

Fig. 11 shows two sections A connected with a section B. The steam fiows in the direction of the arrow 38 and the condensate, which is caught by the trough 33, is conveyed to the chamber 36 in which it raises above the outlet 3'?. The pressure in the radiator forces the condensate through the outlet 37, up through the pipe 39, and into the water Well 11, in the adjoining section A, from whence it flows through the water wells in the other sections as indicated by the arrow 40.

Three sections A and a section C are shown in Fig. 10. The section C, in addition to having the chamber 36, is also provided with a water well and the pipe Lil leads from the chamber to the water Well. As in Fig. 1l, the steam flows in the direction of the arrow 42 and the water iiows through the wells in the direction of the arrow 43. The views Figs. l0 and l1 are merely shown to facilitate the description and it is evident that sections A, B or C may be arranged in any combination in a radiator and that any number of each may be used in such a combination. In practice, a well may be placed on the pipes 39 and el.

From the foregoing it will be noted that the construction and operation of this device is very simple and that it does not alter the general outline of the radiator, nor does it unduly addto its cost. It will also be noted that by having a relatively shallow streain of Water iiowing through the humidifying devices, rapid evaporation will take place; the maximum evaporation being reached when the hot water or condensate is used.

While I have shown orifices, cast in the sections, through Which the water vapor escapes, it is evident that removable, perforated covers might be used. It is also evident that sections, such as shown at A, may be made with or without Water wells.

While I have illustrated sections of certain types, it will be understood that the invention may be used in sections of other types, whether cast or made oi pressed metal. It will also be noted that the chamber 36 may be made of any other size or shape than that shown, and that the trough 33, instead of being cast integrally with the section, might be inserted through the inlet 34.

Having described my invention and its opg eration, what I claim as new and wish to protect by Letters Patent is:

1. The combination with a radiator section of a humidifying device consisting of a Well cast integrally with the section but separated from the steam space thereof, of means forming a tortuous water passage through said well, of means for inducing a shallow stream of water to flow through said tortuous passage to be vaporized by the heat in the section, and of means through which the vapors are liberated from the humidifying device.

2. The combination with a radiator section of a humidifying device consisting of a well lo cated within the section but separated from the steam space thereof, of a condensate-collecting chamber contained Within the section, of means humidifying device or devices, and means for -rliberating the vapors from the humidifying device or devices.

4. In a sectional radiator, one or more sections having condensate conveyers, one or more sections having condensate-collecting chambers, 1;

one or more sections having humidifying device means for conveying the condensate from said chamber or chambers to the humidifyingdevice or devices, and means for liberating the vapors 'from the said humidifying device or devices.
