,This invention relates to improvements in heating apparatus, for example stoves, and it consists of the constructions, combinationsand arrangements herein described and claimed.

An object of the invention is to provide a hood or superheaterA for a stove or any other kind of circulating heater-said hood l being incorporated therein in such a inanner as to cause the greater volume of incomi air tofollow the contour of a'highly heated drum, said hoodhaving an openin or openv ings at the .top through which t e`heated is shown to 'have a top 10 which is perfoh 12' for the egress of.

a1r yis discharged at a considerable speed,

thereby insuring the heating of the room 1n a rapid and uniform manner.

. Other objects and advantages appear in the following specification, reference beiner had to the accompanying drawing, in which Figure 1 is a perspective view of the Stove 1n use. I 4

Figure v2 is a lcentral vertical section.l Figure-3 is a detail perspective view of the hood.

In carrying out the invention provision is made of a fire pot orbowl 1 having an appropriate type of grate 2 upon which the pot, andthe drum is surmounted by a semiglobular dome'4 from which the products of combustion escape by way of. the` pipe 5 to an appropriate flue. The' fire pot drum 3 and dome 4 constitute they-central body or heating element of the stove which is-enti'rely closed so far as the immediately surrounding heating space isconcerned.

The fuel is. introduced into the stove through a char 'ng door 6 and ashes are removed from t e pit 7 through a door 8. The shell 9 constitutes the outside jacket which is designed along such lines as to give the stove theydesired appearance as illustrated in Figure 1'. Here the jacket rated both at 11 'and heated air.

Brackets 13 support a tubular imperforate heat screen, or partition 14 in spaced relationship to the drum 3. Other brackets 15, secured at 16 to the `the hood 17 orso-called superheater in rspaced relationship to the .dome 4. The

hood has an opening or openings 18 through which air admitted at an appropriate opening19 in the bottom4 of t e stove escapes dome 4 supports after having been forced to follow the contour of the drum 3 and dome 4 by the parv tition 14 and the hood 17. The 'latter is' situated in the heating space mentioned be fore. The hood has a notch-20 which --fits over the y smoke pi e 5. space between the Ahood 17 an Ithe dome 4 is'greater than the space between the par- (Fig. a)

tition 14 and the ,drum 3 for reasons which` appearing'in the following' Operation.

As stated before, the cool air is admitted into the'heating space' of the stove through. an appropriate ,opening 19 in the bottom (Fig. 2). The partition 14 and hood 17 are intended tol cause 'the greater '."volumc of incoming air to follow the contour yot the heating element. The partition 14 is closerk to the drum 3 than it is to the shell` 9, thereby making the space on the outside of the partition somewhat deeper` than the space, on the inside. But the lvolume of air passing' through the inner space is intense y.heated, because it repre-l sents a thinner layer and passes directly It has also been stated that the space betweenl the Idome 4 and hood 17 is greater than the space between the drum 3 and ar.-

' the partition 14 but also some-of the air from the outer s ace. It is now Aapparent that the space wit in the hood may be made somewhat larger as it receives double por-A tions of air. l

But the hood also follows the contour of the dome 4, and by virtue of this fact the,

air received thereby is subjected to the very ot dome and furthermore vhas imparted thereto considerable velocity which sends it directly upward through the o ening 18 and out of the p'erforations 12. ther volumes of air, not subjected to the foregoing extreme heating action escape at the perforations 11, but the ultimate result is that all of the heated airpasses upwardly in the room.

By virture of the fact that the air is sube to a vigorous lheating action and ejected ond the screen so that the space- The over rthe drum 3 which, presumably, is very coals are supported. The tubular drum 3 h constitu-tes an upward,V extension of the lire With an equally vigorous action, the

lllA

room becomes heated both quickly and uniformly. It is an obvious result that if more of the heat units of they fire can be utilizedl for the useful purpose of heating the air the stove in which the foregoing principle is embodied becomes more eflicicnt than other stoves. And a further result must necessarily follow that a substantial saving in fuel w11l be had.

While the construction and arrangement of the heating apparatus is that of a generally preferred form, obviously modifications and adaptations in the form thereof herein described may be made without departing from the spirit of the invention or the scope of the appended claims.

1. Heating apparatus comprising a heating element which includes a tubular drum and a substantially semi-globular dome having a lateral smoke outlet pipe, a shell constituting the outside jacket of the apparatus having air inlet and outlet openings, an

open ended tubular partition in concentric spaced relationship to the drinn` a hood shaped substantially like the dome but being' spaced farther therefrom than the partition is spaced from the drum leaving a circumferential opening for the ingress of air from the space at both sides of the-partition, said hood having a notch fitting over the outlet pipe and "a top central opening aligning with the shell outlet opening for the esca e of heated air, and means for simultaneous y supporting the partitionv and hood, said means including brackets carried by the drum and other brackets' carried by the dome.

2. In combination with a combustion chamber having av dome at the top, supports radiating therefrom, a centrally orlced hood placed upon said supports in spaced relationship to the dome providing a circumferential air inlet at the lower` edge thereof for directing the air passing up the side of the combustion chamber' and into said inlet acrossthe top of said dome. l

3. 1n combination with a combustion chamber, a dome closing the top, contiguous supports radiating from both the combustion chamber and domethe latter supports being longer thanthe former, a (partition.

depending from the shorty supports being open at the bottom and top, and a centrally oriiiced hood placed upon the long supports being spaced farther from the dome the partition is spaced from the combustion chamber thereby defining a circumferential air inlet at the lower edge thereof both inside and outside of the partition.
