Application filed September 29, 1925. serial No. 59,284.

My invention relates to a heating device and has particular reference to astove using a gaseous fuel, the principal object of the inventionbeing to provide a simple, economical and efficient stove in which the combusarea to be heated to uniform temperature,

and to varying degrees of temperature. without coldor hot zones;. to provide a heater which is entirely air insulated, and hence may with perfect safety be placed in walls I and to provide a heater by which pure fresh air may be delivered into and circulated about a room or other enclosure, and. heated to a degree that'will provide a comfortable atmosphere without impairingthe vitality of the pure air byoverheating and drying;

mounting the fines 1n this manner, serv ng-to Other objects will appear from the-followingl specification'in connection with the accompanying drawing, which illustrates a preferred embodiment of the invention, and in which I 3 Fig. 1 is a front view partly broken showing my invention.

Fig. 2 is aside view partly in section, the

' section taken approximately on line -2.2.

Fig. 1, and I Fig. 3 is a sectional: plan view on line 3-3 Fig. 1.

My'invention is forms in which it may be carried into practical effect and as comprising in a general sense astructure having a communication with the atmosphere, for leading into a closed area the outside air, and another communication with the atmosphere' for continuously carrying out the air from the closed area, with ameans for heating the introduced atmospheric 1 air.

In a more specific sense, the invention as shown in the preferred manner of construc tion, comprises acasing 1 formed with sides 2, back '3, and top 4 and which-1s open at the front and bottom. The sides 2, at] the bottom thereof are formed into or pro-,

vided with ducts or passageways 5, which .efliciently absorbs the heat'ofthe fines on shown in one of many communicate in any desirable manner with the atmosphere outside anenclosed areaor space. 1 These ducts 5 extend the full-depth of the sides 2 and are of limited height and width, and serve to convey the atmospheric air from 'the;bottom into a-room or other area, as will appear later. To therear or back- 3 of the casing andbetween the, ducts .5, is fastened in any desirable'fmanner, a

partition 6, constitutinga stack, extending vertically through said case 1 and at the bot tom being in open communication withthe closed area tobe heated or'ventilated, the, partition 6, for this purpose terminating,'a short distancefromthe bottom, and providing a free entrance of the used heated air into said stack.

The upperarea of the stackftl is enlarged,

as seen: at 6, and extends abovethetop of the casing 1, andto: the wall? of, said-stack enlargement'are connected the elbows 8 of Y aplurality of spaced lines 9, thefelbows'flS i being, as seen, n communication with said, stack. These elbows 8 are connected to the wall 7, at a short distance from the top 4 ofthecasing 1, the space-A created by I permit the incoming air to pass over the; top of the fines. The flues 9, as seen, are also spaced from each other, from the side walls 2 and from the back 3 of the casing l, and being thus entirely freely suspended within 1 the'casing, the incoming cold air readily and all sides and travels into the room inhe'ated condition, the temperature depending upon the heat in thecombustion chamber 10. The flues' 9 are conjoined with the combustion' chamber 10, in which is disposed a burner ,11, connected with a source of fuel/supply,

not shown. The-top of said'combustion chamber is provided with"openings 11"'- flues .9. These openings are considerably 'throughwhich the heat of combustion es- I capes from thecombustion chamber into .the

smaller than the flue openingsandare thus desigm'ed to retard the flow. of the heat of combustion and thereby insure the fullest-ex'e pansion of samewithinthe flues. As shown, the combustion chamber' lO is carried, or' supported by the flues 9. any suitable connection being used for this. purpose, such for instance as that illustrated in Fig. 1. i-

and comprising an upstanding collar 12fon Y th 3 f 'th combustion chambercto which the flues '9 are fastened bybolts or other means. The construction, of suspendng'the fines and the combustlon chamber provides a cold air space entirelyaround these parts and between them and the.cas

ing', and automatically insulates them from the casing;

heat in the combustion chamber 10, the air space between the casing and fines, and-between the fines efficiently insulates the casing from the heat, which is absorbed bythecold air entering from the bottom. Special insulati'on, as covers, blocks or sheets of asbestos,

' for other the proof materials are thus rendered wholly unnecessary, and a heater of this type may safely-be placed and concealed in the walls of a building.

Below theburner 11, in the combustion chamber 10, I preferto place a baffle plate 12' which is suitably supported above the bottom 13 of the combustion chamber, and which serves to deflect the air entering the combustion chamber 10 through ports 14in the bottom 13, around the burner, and thereby prevent roaring, which would otherwise occur.' Beneath'the combustion chamber 10 I prefer to placea means for preventingv the transfer of heat from the combustion chamber to thebottom and for confining the heat,

and directing also the incoming cold air about the combustion chamber. This"means maybe in' the'form ofa plate 15, extending longitudinally of and under the combustion "anjupstanding portion 15 extending in front ed into the ports chamber 1'0, and supported upon the walls of'the ducts '5'. The plate 15 is formed with of and for thefull width of'the' combustion chamber 10, this upstanding portion co-op- *erating with the plate 15 for the purposes dealso for causing a part ofthe scribed, and incoming cold air to bedeflected and divert- 14 in the bottom of the combustion chamber.

7 From the construction as outlined,.it will be observed that atmospheric air enters through the side ducts 5 and travels upwardly in the space "B (Fig. 1), between the .side walls 2, the combustion chamber 10 and the flues 9, and also behind the fines.

To prevent the immediate ingress of the outside air through the ducts 5into the area to be heated, and direct it into immediate contact with the flues or into the area behind between the flues,

the fines to necessitate it passing between and being heated by said fines, I prefer to provide'a cover'16, formedto fit over the'fr'ont of the casinglp'and provided with side panels 17" which elose'the spaces B between the'side walls 2 and the combustion chamber 10 and fines 9 to divert the incoming air to This cover 16 is also provided with an upper horizontal panel 18,

which extends below the top of the casing 11 and slightly above the topof the'flues 9 to retard the air fiowand heat same and with Therefore, regardless of the 7 directly into ways pure and fresh. not desired, the stove herein described acts 'heatingmeans within said casing a lower horizontal panel 19, which serves to confine the area about the combustion chamber 10, and is disposed above the bottom to provide and permit free passage-of the air. These panelsil'i, 18 and 19, also serve to support a wire or other mesh 20 of any configuration and are preferably designed to provide an ornate enclosure, which in addition to performing the functions re- 7 around-and between the fines 9,'-passes into the-room or other area and" displaces the colder air therein, the displaced air, which is the lower stratum, being forced and drawn out of the area through the stack 6, which is at the bottom in direct and open communication 5 with the area to be heated. The

energy with which the cold air or the used air is forced and drawn out from the closed space is augmented by the hot combustion gases which escaping from. the fiues 9, enter the stack 6, above thepoint of communication ofsame with the'closed area. In'this wise, the air in'a room or other enclosure iscontinuously"displaced, without creating noticeable and objectionable drafts.

A moderate, comfortable temperature may bemaintained' at all times, and the air. 18 al- VVhen. heated air is as a ventilator, permitting a continuous inflow of fresh air and an uninterrupted out-.

flow of the used air withoutthe necessity of opening windows or other outlets that develop drafts and induce undesirable air current with the accompaniment of. dust and other objectionable matter.
