r ar HUMIDIFIER FOR HEATERS.

Specification of Letters Patent.

Patented June 13, 1922.

Original application filed September 25, 1918, Serial No. 255,700. Divided and this application filed April 21, 1919, Serial No. 291,709. Renewed April 22, 1922. Serial No. 556,117.

To all whom it may concern Be it known that 1, ROBERT NICHOLAS MURPHY, a subject of the King of Great Britain, and resident of the city of Ottawa, in the Province of Ontario, Dominion of Canada, have invented certain new and useful Improvements in Humidifiers for Heaters, of which the following isa specification.

This invention relates to improvements in humidifiers for heaters, and forms a divisional application to my application for heaters, Serial No. 255,700, file-d Sept. 25th, 1918, and the object of the invention is to permit of the air or other heating fluid passing through the heater taking up the desired amount 0 moisture to give the best heating results.

With the above object in view the invention consists essentially of the improved con struction hereinafter described and set forth in the following specification and accompanying drawing forming part of the same.

In the drawing:

Figure 1 is a vertical section of a hot air heater showing my improved humidifier mounted therein.

Figure 2 is a transverse section through the heater and humidifying apparatus.

Like characters of reference refer to like parts in the several figures.

Referring to the drawing, a heater A of the hot-air type is provided with a passageway 15 between the combustion chamber 10, the fire pot 11 and the outer jacket or wall 14:, and an inlet conduit 25 is provided through which a supply of air is delivered into the passageway 15. In this heater the humidifier consists of a transverse pipe 26 communicating with the passageway 15 at the upper end thereof, the said pipe being formed with a depending tube 27 closed at the bottom end and formed with a clean out plug 28.

This depending tube is provided with an inlet conduit 29 intermediate of its height and the air passing through the conduit 29 impinges on the baflle wall 30, so that 1t is caused to flow across the top of the liquid 31 contained in the tube 27. i

This liquid is preferably water and is maintained at a predetermined and constant height by means of a reservoir 32 which is connected through the pipe 83 to the tube 27 When this furnace is in use the air enters the conduit 25 and when heated ascends the passageway 15, is caused to flow over the surface of the water or other liquid in the tube 27, and takes up the desired amount of moisture therefrom, and this moistened air travels upwardly through the tube 27 into the pipe 26 and thence into the passageway 15 and may be discharged therefrom through any suitable conduit.

The air on its passage through the tube 27 and pipe 26 is adequately heated and this air commingles with the air which passes! through the passageway 15 and is heated therein, so that the air ultimately discharged from the heater will have the desired amount of moisture.

Air is forced through the conduit 29 and across the surface of the water in the pipe 27, and then upwardly through the pipe 27 into the pipe 26, and in this case the air and steam pass through a relatively hot zone and become heated to a very high degree before being delivered from the pipe 26 into the passageway 15, so that the temperature of the air will be at the proper degree, and the humidity such as is designed to give exceptionally good results in heating systems.

From this description it will be seen that I have invented a humidifier which is of simple construction, not liable to go out of repair, and in which the amount of water vaporized is controlled by the intensity of the heater, so that the amount of humidity taken up will not be in excess to the heat of the air circulating through the heater.

As many changes could be made in the above construction, and many apparently widely different embodiments of my invention, within the scope of the claim, constructed without departing from the spirit or scope thereof, it is intended that all matter contained in the accompanying specification and drawing, shall be interpreted as illustrative and not in a limit ipg sense.

What I claim as my invention is:

In a hot-air furnace, a fire pot, an air passageway surrounding the fire pot, an inlet for the air passageway, an outlet for the air passageway, a transversely extending pipe connecting opposite sides of the air passageway, a pipe depending from the transversely extending pipe and having a closed lower end forming a water receptacle, a branch pipe connecting the air passageway with the depending pipe, and a baffle wall overhanging the end of the branch pipe to direct the air downwardly over the water in the depending pipe.

h Injl witness whereof I have hereunto set my ROBERT NICHOLAS MURPHY.
