HUMIDIFIER,

Application filed. March as, 1930. Serial No. 439,760.-

densation within the steam diffusing pipe by arranging said pipe to lie,- throughout all or a major portion of its length, in close proximity to the live steam pipeto which it is connectecl. v

A further object is to provide the steam diffusing pipe with steam discharge openings arranged opposite and close to the live steam pipe, so that the impingement of the escaping steam upon the heated surfaceof the live steam pipe further retards the formation of condensate.

A still further object is to provide novel means for causing evaporation of the con densate formed within the steam diflusing pipe. 4 i

Other purposes, advantages and characteristic features of the invention will be more readily understood from the following de tailed description and accompanying drawings, wherein Figure 1 is a perspective view of a radiator and live steam pipe assembly equipped with my invention. 7

Figure 2 is an enlarged fragmentary detailed view of the live steam. supply pipe showing clearly the manner in which my invention is associated therewith.

"' section, of a slight modification.

Referring more particularly to the drawings, l1 designates a radiator equipped with a live steam supply pipe indicated at 12. Pipe 12 may be provided with any suitable form of valve 13 for controlling admission of Another object is to reduce steam con-' Figure 3 is a view, principally in vertical i any cooling present invention, I provide a valve casing 14 steam to the radiator 11. According'tothe which is connected to the pipe 12 between the V valve 18 and the source of steam- Valve casing 1 1i may be equipped with any suitable type of valve 15 for controllingthe flow'of steam from the pipe 12 to the steam difiusing pipe 16. Diiiusing pipe 16 is formed to present a vertical portion 16a lying in close proximity to the live steam pipe 12 and an offset upper portion 16?) connected to the bottom of the valve casing 14. The vertical portion 16d of the diffusing pipe 16*is formed with a plurality of relatively small openings 16o positioned close to and directly opposite the live steam pipe 12. At its lower end, the vertical portion16a of the diiiusing pipe is provided with arelatively small opening 16d forthe escape of condensate. Y

When the valve 15 is opened, steam flows from the live steam supply pipe 12 through the valve casing 14 into thesteam diffusing pipe 16. The steam escaping fromthe pipe 16 through the openingslficimpinges direct- 1y upon the adjacent heated surface of, the live steam pipe 12, so that condensation is reduced to a minimum. Condensation of the steam within the difi'using pipe 16 isalso, re-

tardedv by the arrangement of this pipe to extendinclose parallel relation with respect to the heated live steam supply pipe 12. The small amount of condensate forming within the diffusing pipe 16 fio ws. downwardly through openings 16d onto a suitable absorbing material 17 which may consist ofblotting paper wrapped around thelive steam pipe 12 andjh'eid in place by suitable split clamps 17 a. 'ofwell-known construction. By reason of. its contact with the pipe 12, the absorbent material 17 i is maintained at a sufficiently high temperature to elfeot rapid evaporation of the condensate delivered thereto- The thickness of the absorbent'material 17 should be. relatively slight sothatfthe. entire body oi: the absorbent material may be maintained at a temperature sufliciently high to prevent of the 1 condensate delivered thereto. 5 In Figure 3, I have shown a desirable modification, wherein the steam diffusing openings.

1.9 are confined to the lower portion of the diffusing pipe 20 and are covered by the upper portion of the absorbent material 21 to which the condensate is delivered.

In the foregoing I have disclosed several Ways in which the steam delivered to the steam diffusing pipe is permitted to escape into the atmosphere. It will be understood, however, that this feature of the invention may be varied to provide for escape of the steam into the atmosphere in any sutiable manner, although, in certain installations, it will be found preferable to have the escaping steam directed against the heated steam supply pipe, as shown in Fig. 1, as this materially reduces condensing of the escaping steam; In both forms of the invention, as herein disclosed, it Will be noted that the condensate formed within the steam diffusing -3 pipe is delivered to a highly heated body of absorbent material so that rapid evaporation 'of the condensate is provided for in such manner as to avoid objectionable drippage. --This' delivery of the condensateto an absorbent body of material heated by the live steam pipe is a very important feature of the invention. It provides for rapid evaporation of the condensate and practically eliminates drippage.

I claim:

1. The combination with a vertically extending live steam pipe, of a vertically eX tending steam diffusing pipe having its upper end connected to said live steam pipe, said at diffusing pipe being provided with a plurality of openings for the escape of steam and with a bottom opening for the escape of condensate, and a body-of absorbent material si'irroui'iding the live steam pipe and posi- 40 tione'd to receive the condensate formed Within the diffusing pipe.

2. The combination with a live steam pipe of a diffuser connected thereto and functioning to diffuse steam into the atmosphere, said diffuser having an opening in the lower portion thereof for the escape of condensate and a body of absorbent material surrounding the live steam pipe and positioned to receive the condensate escaping through said opening. 3. The c'on'ibination with a vertically extending live steam pipe of a vertically disposed difi'user connected thereto and functioning to diffuse steam into the atmosphere, said diffuser having an opening at its lower end for the escape of condensate and a body of absorbent material covering said opening and surrounding the live steam pipe, the arnngement being such that the absorbent material is heated by the live steam pipe so that the condensate absorbed by said material i evaporated into the atmosphere.

In Witness whereof, I have hereunto set my hand. I

. ANDREW Ur JONES.
