9 claims. (01.126-113) The main object of this invention is to provide a humidifier well adapted for use Yin hot air furnaces and the-like. Y l
Another object'of my invention is toy provide 5 I a humidifier comprising a water pan of improved construction and having means associated therewith for supporting the same in the top or bonnet of the furnace in a novel manner.
Objectsk relating to details and economies of lomyl invention willV appear from the descriptionA to follow. The invention is Idefined and pointed out in the claims. v Y
A structure which is a preferred embodiment of my invention is illustrated in the accompanyl5 ing-drawings, in which:Y
Fig. 1 is a fragmentary top plan View of a hot air furnace embodying the features of my invention, a portion ofthe top of the furnace bo-nnet being broken away to show the water pan. 20 Fig. 2 is a fragmentary view in side elevation, a portion of the furnace top being broken away 5 and shown in vertical section.
Fig. 3 is an enlarged detail section of the water pan'taken on a line corresponding to line 3--3 Y 25 of Fig. 1. Y .Y Fig. 4 is a fragmentary section on a line corresponding to line fl-II of Fig.5. v
Fig. 5 is an enlarged fragmentary section on a line corresponding to line 5-5 of Fig. 4. 301 Fig. 6 is an enlarged perspective view of the hood. l
Fig-7 is a rear elevationof the rear escutcheon and adjustable slide. assembly.
In the embodiment of my invention illustrated 35'n in the drawings, numeral I indicates a hot air furnace having a top or bonnet 2 provided with an inwardly inclined or conical wall 3. The air isheated by the furnace and circulated upwardly through the chamber l formed by the bonnet 40' and outwardly through the conduit openings 5, 5
which are conventionally. illustrated, the conduits not Ybeing illustrated. y I provide the wall 3 of the. bonnet with oppose-d openings surrounded and reinforced by the front 45- and rear escutcheons 6 and l respectively. These escutcheons are preferably curved to fit the wall 3 and are secured thereto in any suitable manner as by means of the bolts 8. escutcheon is provided with a central opening 9 the `lower halfV of which is adapted -to receive the channel-like'neck Il! of the relatively shallow water pan Il disposed within the chamber 4, the bottom ofthe channel having a flange 30 en- 5'51ggaging the frontV of the escutcheon. The chan- The front nel I is tiltably supported bythe lower edge of the opening 9 of the escutcheon 6. Y
The channel I0 is covered by means of a hood I2 which loosely fits Within the upper half of the central opening in the front escutcheon, the
top I3 of the hood being curved downwardly and inwardly to t the top of the opening through a wide range-of inclinations of the front escutcheon (see Fig. 4). My humidifier is thus made readily adaptable to hot air furnaces having bonnets-10 the side walls of which slope at different angles. The hood is removably disposed on the channel I0 and is provided with a flange I4 for coaction with the removable cover l5 of the water inlet or float Vchamber I6. The water admitted to the float chamber is controlled by the float valve I1 which is conventionally illustrated, the water pipe being shown at I 8, Fig. 1. A drain cock is provided at I9 for cleaning the pan.
lThe rear escutcheon lis secured to the wall 3 20 and is provided with a vertical central opening through which the overflow pipe 2D extends, the inner end of the pipe being connected to the inner end of the pan II as shown for supporting the latter. The overflow pipe is supported by 25 the vertically adjustableslide 2l associated with the rear escutcheon-A1. The position of the slide is controlled by the screw 22 by means of which the Voverflow pipe' 20 and water pan I I can be adjusted to their proper level. The water pan II is elongated as shown, the necky I0 extending through the wall 4 -being relatively deep and narrow. The neck merges into a central longitudinal concave channel 23 of increasing width anddecreasing depth toward the inner end of the pan. The inner end of the pan is semi-circular as shown by Fig. 1. The channellike neck also merges into a peripheral upwardly sloping ledge 24 ofsu'bstantially uniform depth and of increasing width toward the inner end-of the pan. The overflow outlet is disposed slightly above the bottom of the outer ledge 24 whereby there is provideda bodyoi water having a relatively deep `central portion: substantially surrounded by a relatively shallow portion, the two providing a large Water evaporating surface.
z For this reason, my humidieris of exceptionally large capacity and functions eciently to supply the warm air circulating through the bonnet 2 with the proper amount of moisture. The 50 relatively deep central-channel 23 provides an adequate supply of water at all times while the ledge'24 acts to quickly evaporate theshallow water thereabove.' By shuttingV` off the water supplyfand opening the" drain cock I9, the entire contents of the pan may be drained inasmuch as the drain cock is placed at the lowest point, there being no obstructions in the path of the water thereto. My improved humidifier is extremely simple and economical in its parts and yet it is very eiective and efficient for the purpose intended.
I have illustrated and` described my improvements inan embodiment which I have found very practical. I have not attempted to illustrate or describe otherA embodiments or adaptations, as it is believed this disclosure will enable those skilled in the art to embody or adapt my improvements as may be desired.
Having thus described my invention,V what I claim as new and desire to. secureibyLetters Patent is:
