The present invention relates to humidifiers adapted to be combined with gas heat ers, and the primary object of the invention is to provide. a device of this Character which will be found especially well adapted for use in residences for supplying clean and moisture laden air to the rooms.

A further object of the invention is to provide apparatus of this nature embodying an arrangement whereby the hot air currents from the heating element will be directed upon a body of water in such manner as to become thoroughly moistened before being discharged into the atmosphere about the heater.

A further object of the invention resides in the novel arrangement whereby the hot air currents from the burner are directed laterally thru a steam chamber so as to thoroughly co-mingle with the steam before escaping thru suitable vent-s into the room.

A further object of the invention resides in the provision of a gas heater embodying in its construction air moistening means oi novel construction for thoroughly moistening the hot air currents from the burner prior to escape of the hot air from the heater.

A still further object of the invention is to provide an air moistening device which may be readily and easily associated with existing types of gas heaters whereby clean and moisture laden air will be supplied to the room.

A still further object of the invention is to provide apparatus of this character embodying a reservoir for the water which may be so related to the burner as to cause the water to be quicklyheated for generating steam with which the hot air currents from the burner co-mingle.

Referring to the drawings in detail, and

wherein similar reference characters designate corresponding parts thruout the several views, the letter A designates a conventional type of radiant gas heater and B and C slightly modified forms of humidifiers for detachable association with the heater A.

The gas heater A as shown in each of Figures 1, 2, 3 and 5 is of usual construction embodying a metallic casing 10 being open at its front side and provided with suitable supporting legs 11. The casing 10 is of substantially rectangular shape in formation and is provided with side walls 12, a top wall 13, and a back or rear wall 14 shown in Figure 3 which in ordinary practice is provided at its vertical center and adjacent its upper .end with a rearwardly projecting collar 15. A cap 16 as shown in Figures 1, 2 and 5 is supplied with each heater for closing the flue vent formed by the collar 15 when it is not desired to attach the vent pipe to the collar as shown by dotted lines in Figure 3 and wherein the vent pipe has been shown applied to the flue vent of the humidifier. Mounted in the open casing 10 is the usual radiant or heating element 17 heated in the usual and customary manner by a gas burner not shown, and arranged over the front open side of the casing is the usual guard 18.

Referring now to the specific construction and manner of attachment of the form of humidifier B as shown in'Figure's 1 to 4 inclusive, and which device is intended to be applied to the rear side of the heater A, the same is constructed entirely from sheet metal to provide a water tank or reservoir 20. This receptacle or reservoir 20, and which is relatively narrow as to thickness, is formed with flat front and rear walls 21 and 22 respectively, straight end walls 23, and a flat bottom 24. The upper end of the tank 20 is provided thruout its length with a forwardly offset hollow shelf forming portion 25 the lower wall of which is intended to rest upon the top wall 13 of the heater. The end walls of the hollow projecting portion 25 and which form continuations of the end walls 23, project below the bottom of the shelf forming portion to provide attaching plates 26 which may be apertured as at 27.

Provided at the vertical center of the front wall 21 and spaced slightly below the portion 25 is a circular-shaped opening 28 of a diameter slightly greater than the diameter of the heater collar 15. Arranged at therear wall 22 and inaxial alignment with the circular opening 28 is a collar 29 forming a flue vent for the receptacle 20. This collar 29 is of a size equal to that of the heater collar 15 and is intended to receive ture 31 in the heater side walls for the usual cap 16 ordinarily employed for closing the flue vent of the heater formed by the collar 15. The tank 20 is of a height and width substantially equal to the height and width of the heater casin 10 and is intended to be applied to the eater with the front wall 21 of the tank engaging in surface contact with the rear wall 14 of the heater, and the. shelf forming portion 25 projecting over the top wall of the heater so as to act as a support for the tank. The depending plates 26 will engage the side walls 12 of the heater and a suitable bolt or the like as at 30 in Figure 2 may be passed thru the apertures 27 and an aligning aperetachably connecting the upper portion of the tank to the heater. The front tank wall 21 may be rovided at its lower end with an apertures attaching ear 32 which may be secured to the lower portion'of the heater as by means of a bolt or the like 33. Thus it will be seen that the bolts 30 and 33 serve as means for readily and detachably vconpling the tank or water receptacle to the heater.

The top wall 34 of the shelf forming portion 25 has hingedly connected to its rear edge a plate-like lid 35 which may be provided at its free edge with a yieldable tongue 36 for hooking-over a. suitable pro jection provided at the upper edge of the rear tank wall 22. As will be observed in Figure 3, this hinged lid 35 is arranged immediately above the tank proper and provides means whereby water may be easily placed in the tank upon opening the lid.

' When the lid 35 is closed it will be seen that the lid and wall 34 will provide a fiat top which is spaced from the top wall 13 of the heater and thus will not become excessively heated as to prevent placing of objects upon the top of the humidifier.

Provided in each of the end walls 23 of the tank and arranged in horizontal alignment with the collar 29 is a suitable number of small openings 38 providingvents thru which the humid air may escape from the chamber formed in the upper portion of the tank.- These vent openings 38 are formed in the end walls 23 below the extension 25 so as to prevent escape of an' excessive amount ofsteam from the device. -Thus it will be seen that a pocket is formed in the upper portion of the tank, and a portion of the steam will be condensed upon striking the top wall 34 and lid 35 and. be returned to the tank proper without being carried thru the openings 38.

' Adapted for positioning over the heater collar 15 is a deflector 40 embodying a sleeve portion 41 for slidably fitting over the collar and 'a baffle plate 42 arranged at such an angle as to cause the. hot air currents from the heating element 17 to be directed downwardly into the tank 20 as shown by the arrows in Figure 3. This baflle 42 is in the form of a hood and when the deflector is in position on the collar 15 acts to prevent any products of condensation from entering the opening formed by the collar 15 and passing into the heater casing. The

The water is placed in the tank 20 andmaintained at an elevation approximately as shown in Figure 3. When the burner for heating the radiant 17 is lighted, the surface contact between the heater and tank walls 14 and 21 respectively will cause the water in the tank to be heated to an extent for producing a small amount of steam in the upper portion of the tank. The hot air currents from thera'diant 17 will be directed thru the collar 15'and deflected downwardly uponthe water by thebaflie 42 at the center of the tank and then pass laterally in each direction toward the ends of the tank thru the steam before escaping thru the vent openings 38 at each end of the tank. The

upper end of the receptacle, and which lid may be provided with a spring catch 50 for engaging over a suitable projection provided at the upper edge of the rear wall 46. Provided at the vertical. center 'of the front wall 45 and spaced below a are provided with a suitable number of openings 53 which are spaced below' the upper edges of the Walls and preferably in horizontal alignment with the opening 51. A- deflector 40' as referred to in the description of Figures 1 to 4 inclusive is applied to the' collar 15 for directing the hot air current downwardly into the tank and then laterally across the water surface to the vent openings 53.

The upper portion ofthe front wall 45 is provided} with suitable apertures 54 thru which suitable bolts 55. may be passed for attaching the receptacle to the rear side of the heater. The lower end of the wall 45 may be provided with an apertured tongue 56 for attaching the lower portion of the receptacleto the heater.

With the form of humidifier as shown in Figures 5 and 6 and wherein the device is provided with a flat front side, such will permit of this type of device being applied to practically all types of gas heaters having rearwardly opening flue vents, regardless as to the width of the heater or the specific location of the collar 15.

Referring now to Figures 7 and 8, and wherein the humidifier has been combined as an integral part of the heater, the device has been shown as comprising a casing 60 v embodying end walls 61, a rear wall 62, and

a bottom wall 63. Arranged vertically within the casing 60 inparallel relation to the rear wall 62, is a partition plate 64 which extends thruout the height of the casing and divides the same; into tank and burner compart-ments 65 and 66-respectively. The partition plate 64 is provided at its upper end and at a point midway between the side edges with an opening 67 forming the only means of communication between the tank and burner compartments. The front side of the compartment 66 is open and this compartment is intended to house a suitable burner heated radiant 68. A guard 69 may be arranged over the open side of the burner compartment. The upper end of the burner compartment 66 is closed by a top wall 70, and hingedly connected to the rear edge of the wall v70 is a lid 71 acting as a closure for the tank compartment 65.

A deflecting hood 72 is arranged over the opening 67 and projects into the tank compartment above the water level for directing the hot air current from the burner heated radiant 68 downwardly into the tank compartment and along the surface of the water contained therein. That portion of the end walls 61 which form the end walls for the tank compartment 65 are provided with a suitable number of vent openings 74 which are arranged in spaced relation below the lid 71. The rear casing wall 62 is provided with a tubular extension or collar 75 forming an opening into the upper portion of the tank compartment .65, and which extension is provided with a removable cap 76 for allowing a vent pipe to be applied to the collar when such is desirable.

In each of the three forms of invention shown it will be seen that the water receptacle is relatively flat and is disposed directly behind the radiant so that the body of water will be quickly heated. It will also be observed in each form of device that the hot air currents from the burner enter the water compartment at the central portion thereof and are directed downwardly and caused to travel in opposite directions along the water surface before escaping thru the vent openings provided at opposite ends of the water compartment.

From the foregoing description it will be apparent that an improved device of this character has been provided which will be found especially well adapted for use in connection with gas heaters, and embodying features of operation whereby the dry hot air currents from the burner will be caused to travel thru and caused to co-mingle with a steam vapor before passing into the room.
