The inventionwill be best understood by A steam blow-off valve 31' is connected in a reference to the accompanying drawings communication with'the compartment 1 8. which form a part of this specification, and above the normal water level by the pipe 32. in which, A'by-pass 33 connects the pipe 32 with the air Fig. 1 is a side elevational view of the ininlet pipe 12 so as to humidify the air which vention. is delivered intoitheinteriorof the" shell 11.

It isanobject of the present invention to provide an apparatus of this class in which a force circulation of airflwould be effected Fig. 3 is a sectional View taken on line as of Fig-2.

Fig. 4 is a fragmentary sectional view of the invention illustrating the humidifier.

In the device I provide supporting legs 9 which serve to support the superstructure f comprising an outer shell or housing 10. en-

In operat on, the gas burner serves to heat the Water which circulates through the comof the water and partment 18 and this water willheat the surface with. which the air will be brought into contact. Pipes 36 travel the interior of the shell 11 and the air brought into theinterion I of the shell 11 will-pass upwardly and contact with these pipes 36.; Similarly, that por tion of the air which passes through the conduits- 15 will contact with the pipes 24 and thus the air will become heated. The portion of the; air passing through the tubes or conduits 15 will pass upwardly in the passages 35 and thus inducing a draft from the bottom of the passages drawing more air upwardly into the hood or cover fine 88 and to which suitable piping may be connectedto conduct the hot airto any de-,

sired location. 7

37, fromwhich leads the i 39 supported by the brackets 40 may be used' c as an auxiliary heater.

It is obvious that a simple and compact structure is provided whereby a hot air heats ing system is established with the use of hot water as the heating agent.

When desired, an electric heating element While I have illustrated and described the preferred form of construction of my invention, I do not wish to limit myself to the precise details of structure shown, but desire to avail myself of such variations and modifications as may come within the scope of the appended claims.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is: V V

1. A heater of the class described, comprising: an inner shell; an outer shell spaced from and enclosing said inner shell; a plurality of tubes traversing said inner shell and communicating at opposite ends with the space between said inner shell and said outer shell; conduits extending through the space 7 between said inner shell and said outer shell and communicating with the interior of said inner shell and the exterior of said outer shell; a plurality of pipes communicating with the space between said inner shell and said outer shell and traversing said conduits; and means for delivering air into the interior of said inner shell.

2. A heater of the class described, comprising: an inner shell; an outer shell spaced from the enclosing said inner shell; a plurality of tubes traversing said inner shell and communicating at opposite ends with the space between said inner shell and said outer shell; conduits extending through the space between said inner shell and said outer shell and communicating with the interior of said inner shell and the exterior of said outer shell; a plurality of pipes communicating with the space between said inner shell and said outer shelland traversing said conduits; means for delivering air into the interior of said inner shell; means for delivering hot water into the space between said shells; a cover for said outer shell and providing there- 'with a plurality of vertically extended passages; and a hood covering said shells and said passages.

In testimony whereof I have signed the 5 foregoing specification.

MARLIN WARREN.
