- HUMIDIFYING APPARATUS.

Specification of Letters Patent.

Patented Mar. 16, 1920.

To all whom it may concern:

Be it known that I, ADoLPH \V. LISSAUER,

a citizen of the United States, and a resident of the city, county, and State of New York, have invented a new and Improved Humidifying Apparatus, of which the following is a full, clear, and exact description.

An object of my invention is to provide a unitary structure'of a humidifying apparatus which houses the thermal means necessary for the humidifying apparatus.

Another object of the invention is to provide an apparatus of the class described which is simple in construction, easily accessible and inexpensive to maintain.

In the accompanying drawing forming part of the application, Figure represents a diagrammatic, sectional view through an apparatus embodying my invention.

Fig. 2 is a cross-section on line 2-2, Fig. l.

It is common to supply liquid by gravity that is to be treated thermally and it is customary in some types of humidifiers to provide an overflow by means of nipples rising from the bottom of the sump of the humidifier. These nipples direct the overflowing liquid on to the means for thermally affecting the condition of the liquid. The difficulty encountered in such type of overflow is that it is nearly impossible to have all the nipples exactly on the same level. However, even though it were possible to set all the nipples to a common level the movement of the liquid circulated through the humidifier disturbs the original relation of the nipples and therefore the efficiency ofthe appa- I ratus is decreased.

To overcome the above defects I provide a series of weirs 3 formed. in a rising partition 4 disposed in front of the separator 5. This partition 4 rises suliiciently above the bottom of the separators to form with the rear wall f the humidifier a sump 7, below the separator 5 into which the separator 5 discharges. p

The mist formed-by nozzles 8 that drops before reaching the separators is conveyed by an inclined bottom section 9 of the humidifier, to the sump 7.

The weirs 3 discharge into troughs 10 which are disposed above coils 11. ,The liquid from the troughs drips on said fcoils to be aflected thermally thereby. The coils 11 and troughs 10 are housed in a section 12 of the humidifier structure, which section forms the intregal part of the entire apparatus and is disposed below the bottom of the humidifying apparatus, which bottom as previously described is formed by the sump and the inclined bottom section 9. The weirs 3 being located in the partition 4 their level can be located at will and their relation will not be disturbed by the fiow of 'the liquid for the reason that they are formed in the wall section which is disposed vertically and its lateral fluctuation cannot materially affeet the relation of the weirs and therefore the efiiciency of the apparatus. The deformation of the bottom that may be caused by the flow of the liquid can in no way affect the rising partition wall a and therefore the relation of the weiis. It will, be evident therefore that the outflow of liquid from the weirs will remain constant with the exception that different quantities of liquids may be used from the sump 7 or the section 12 to obtain the desired mixture in the mixing valve 1-4, which will supply the same quantity of liquid, although the proportions of which may differ, to the nozzles 8.

The mixing valve is connected to section 12 by a conduit 15 and to the sump 7 by a conduit 16, also a conduit 17 connects the mixing valve to the pump. The quantity of liquid flowing from the sump and from section 12 to the mixin valve is controlled by a diaphragm 18 wh1ch is affected by the thermostats 19 and 20 located respectively in the air inlet 21 and the passage of the separators.

I claim:

1. In a humidifying apparatus an air chamber through which an air current may be passed, means for supplying moisture to the air current, means for eliminating the excess of moisture supplied, a sump about the means for eliminating the excess of moisture, said sump having weirs in one of the sides, troughs disposed below the sump for receiving liquid from the weirs, means for affecting thermally the liquid disposed below the troughs and onto which the troughs are adapted to discharge, means for vmixing the liquid from the sump and that affected thermally; said last means being connected to the means for supplying moisture to the air current.

2. In a humidifying apparatus an air chamber through which an air current may I be passed, means" for supplying'moisture to weirs in one of itssides for feeding gravitationally. the excess of moisture, onto the means for thermally affecting the moisture, and means for mixin the excess of moisture in the sump, and t at affected thermally,

the said last meansbein'g connected to the means for supplying moisture to the air current.

3.-In a humidifying apparatus, an air chamber through which an air current may be passed, means for supplying moisture to the air current in the chamber, separators for eliminating the excess of moisture, a partition disposed in the chamber transversely of the direction of air flow, and in front of the separators, said partition forming with the walls-of the chamber a sumpabout the separators, said partition having weirs forming an overflow for said sump, and a bottom section in said. air chamber resting on the partition, and disposed to direct a flow of liquid into the sump. v

4. Ina humidifying apparatus, an air chamber through which an air current may be passed, means for supplying moisture to the air current in'the chamber, separators for eliminating the excess of moisture, a partition in the chamber in front of the separators, forming with the walls of the air chamher a sump about the separators, said partition having weirs forming an overflow for )said sump, and, a bottom section-in said air chamber resting on thepartition and sloping toward it so as to cause a flow'of liquid into the said sump over said partition.
