HUMIDIFYING RADIATOR UNI T Rig/2 Patented Oct. 27, 1931 UNITED STATES PATENT OFFICE ARTHUR W. KAPLAN .LND HENRY F. HAUSER, 0F MINNEAPOLIS, MINNESOTA, AS- SIGNORS TO ACE HUMIDIFYING, VENTILATING, AND SHEET METAL WORKS, A CO- PARTNERSHIP CONSISTING 0F HENRY F. BAUSER, T. D. DYNES, AND FRANK A. LUTHER, ALL 0F MINNEAPOLIS, MINNESOTA HUMIDIFYING-BADIATOR UNIT Application led September 13, 1930. Serial No. 481,704.

This invention has for its object the pro'- vision of a simple and hi hly ef'iclent hum1diying-radiator unit a apted to be usedsingly or interposed as one of the units 1n a multiple unit radiator for a heat exchange medium such as vapor, steam or hot water.

To the above end, generally stated, the 1nvention consists of the novel construction'and arrangement of parts hereinafter descrlbed and defined in the claims. U

In the accompanying drawings, which 1llustrate theinvention, like characters indicate like parts throughout the several views.

Referring to the drawings:

Fig. l is a front elevation of a cast metal radiator having interposed therein two of the humidifying units;

Fig. 2 is a view partly in elevation and partly in section taken on the line 2 2 of Fig. 1; and

Fig. 3 `is a fragmentary view in section taken onthe line 3 3 of Fig. 2.

Thenumeral 4 indicates a 'standard cast metal radiator for a heating system and which radiator, as shown, is made up of a plurality of one-column units. Each end unit of the radiator 4 is provided with the customary legs 5 cast therewith and an intake pipe 6 is connected to one of said end units and a return pipe 7 leads from the other end thereof.

Interposed in the radiator 4 are two humidifying units 8 identical, the one with the other, and substantially like the standard unitsas to form. Cast on one face of each unit 8 is a circuitous external water-evaporating passageway arranged for a avity flow of water therein. As illustrate this passageway is made up 'of a plurality of independent troughs 9 vertically spaced, the one above the other, and reversely inclined. The upper end of each section of the passageway is'closed and the' lower end thereof is curved downwardly and arranged to cause water flowing therein to empty into the underlying section of said passageway except the lowermost.

By reference to Fig. 3, it will be noted that the radiator unit 8 is outwardly oiset or, in other words, cored under the sections of the passageways, except the lowermost, to increase the` surface of the passageway with which the heating medium has direct contact to facilitate the heating of the water in said passageway. A copper drain pan 10 is supported directly underth'e discharge end of the lowermost trough 9 of the passageway on the upper end of a branch drain pipe 11 which extends downward through the floor X on which the radiator 4 is supported. Both of the branch drain pipes 11 are connected to a drain pipe 12 which leads to any suitable source of disposal.

Water is dripped or flowed onto the uppermost section of the passageway the upper end portion thereof from a nozzle 13 on a branch pipe 14 leading from a coiled pipe 15 which, 1n turn, leads from a service pipe 16 to which water is supplied under pressure. At the delivery end of the service pipe 16 is a pressure-reducing valve 17 and a cut-off valve 18 is interposed between the pipes 15 and 16.

The

pipes

14 and 15 are always of the same length for different installations and when the length thereof is too great, the pipe 15 is coiled, as shown, to take up the eXtra length thereof. The purpose of always making the

pipes

14 and 15 of the same length .is so that the friction of the water therethrough will always be the same to facilitate the setting of the pressure valve 17.

Interposed in the upper end portion of the branch pipe 14 is a hand-valve 19 for regulating the discharge of water from the nozzle 18 onto the troughs 9. Hot water of any other heating medium in the radiator 4 is in direct contact with the inner side and bottom of the troughs 9, heats the water in 'said troughs as the same flows over its circuitous course and evaporates the same. It is evldent that the amount of water evaporated 1n the troughs 9 is in proportion to the heat required to heat the room in which the radiator is placed and that the adjustment of the discharge of water from the nozzle 13 will be such that substantially all thereof will be evaporated before reaching the lower end of the passageway so that there will be practically no waste. If not all of the water is evaporated by the time it reaches the lower end of the passageway it will be precipitated into the drain pan and carried olf through the pipes lland 12.

It will be understood that one or more of the units 8 may be interposed in a radiator and any number of radiators of a heating system may have the units l8 interposed therein in order to furnish the required amount of humidity.

What we claim is:

1. A multiple unit radiator having formed on one of the sides of one of its intermediate unlts an external evaporating passageway arranged for a gravlty flow of water therein,

and means for vsupplying water to the passageway, said passageway comprising a series of vertically spaced-reversely inclined troughs arranged to progressively empty the one into the otherv from the uppermost downwardly. l

2. A radiator column that is hollow from top to bottom for the circulation of a heating medium therethrough, said column having an.

evaporating passagewayv arranged for a gravity feed of water therein on the exterior of the hollow shell of the column, and means for supplying Water to the passageway.

3. The structure dened in claim 2 in which the shell of the column forms the inner side o the passageway. i

4. The structure defined i'n claim 2 in which the shell of the column forms the inner side and bottom of the passageway.

5. The structure defined in claim 2 in which the passageway is an integral part of the column.

. 6. The structure defined in claim 2 in which the passageway com rises a series of vertically spaced reverse y inclined troughs arranged to progressively empty, the one into the other, from the uppermost downwardly.

7. A radiator column that is hollow from I top to bottom for the circulation of a heating medium therethrough, said column having a circuitous evaporating passageway arranged for a gravity feed of water therein on the exterior of the hollow shell of the column, and means for supplying water to the passageway.

8. A radiator column that is hollow from top to bottom for the circulation of, a heating medium therethrough, said column having on one of its sides an evaporating passageway arranged for a gravity flow of water on the exterior of the hollow shell of the column from. one edge of the shell to the other, and means for- Supplying water to the passageway.

9. A radiator column that is hollow from top to bottom for the circulation of a heating medium therethrough, said column having on one of its sides an evaporating passageway arranged for a gravity How of water therein on the exterior of the hollow shell of the column, said passageway comprising a series of vertically spaced reversely 'inclined troughs arranged to progressively empty, the

one into the other, from the uppermost downwardly, and means for supplying water to the passageway.

10. The structure delined in claim 9 in which the upper ends of the troughs are closed and inwhich the bottoms of the overlying trough terminate short of the closed yends of the underlying troughs, and means tures.
