-One of .the tobjyectsoi the invention is to i provide a housing which can be placed at any desired point within-a room or other en.

closure, said housing holding a grate in such. ainanner that practically all dangers result-v ing from thepuse of fuel inan vopen grate are eliminated, means being employed for controlling the flames sothat they will Vnot which the housing is connected.

, A further Objectis yto utilize baftles'which," by deflecting the flames, also conserve heat and render the grate more eflicient as a heati ing medium. Y

A further ob'iect is to lprovide a structure vof this character which can be cleaned readily. l y ,A

With the foregoing `and lother objectsin view which will appear as therdescripti'on Vproceeds,'the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, itV being understood that changes in theprecise'einbodiment of the A yinvention herein disclosed may be made within the scope of what is claimed, withoutA 'departing from the spirit of the invention.

In the `accompanying drawings the preferred form of the invention has beenshown.

VIn said drawings7 Figurel 1 is a front elevation of a housing i lconstructed in .accordance with the present invention. l

, Referring to' the figures by characters of reference 1 designates ahousing preferably formed of sheet metal. This housing is open at the bottom where itis provided withair inlet apertures 2 in the front wall. The space` within the lower portion of the housing is sufficientlyV large` to lreceive a basket grate Gr, andirons, a gas burner, or the like. The rear portion of the top of the housing is profl vided with an outlet 3 from which products of combustion will escape through a suitable pipe into a chimney. Extending transversely within the'housing is a series of superposed baffle plates 47 these plates having downturned flanges 5 which are riveted orotherwise secured to the sides and back of the housing. The baffles arepreferably inclined n linclosed positions.

.downwardly 'j fo-rwardlyf their forward Clgs are spaced from-'-tlie Yfront Wall of tlieghoi'ising ',:Secgured to tliejfront wall-of said housing.y and'tothe sidewalls j i are downturned vflanges 6 of another series ing extended betweenfjbut spaced fromthe baflies 4. Afconcavereflector in the form of a plate 8 issecured tothe lower baflie 4 and".Y

of superposed baffles-7'theserbaflesibeing inf i i clined downwardly andrearwardly and be-A to the back wall of the housing so that prod- 'u'cts of combustion coming thereagainstrwill y i be ldeflected into. the Vlower endV of ythe :tor-

tuous passage formed by the baffles 4 and?v i while the liglit rays .will be wardly and forwardly.l

reflectedl down- Foi-med Within the from of the -housingi close to the top of each of the baffle plates -7 is a cleanout opening 9 and leach cleanout opening is normally closed by. mea-ns 0f a damper 10pivotally connected to the front of the housing-as shown at 11.` u

j The front of the housing 3 -isprovided.l

below'the lower baffle plate 7 with an'openfv f y are preferably @removably` mounted, therebeing a` longitudinal groove ing 12 adapted to bei' closed by doors13. These doors 14 in the lower edge portion of each doordesigned to receive the bottom wall of thedoor opening asrshown in Figure2 while latches indicated generally at 15 can be employed i for fastening` he upperportions ofthe doors By iiaingaie Corsis from uiefopening 12 fuel can be placed in the grate Gr and. by

`leaving the door opening'uncovered, the heat Y from the burning fuel will -radiate directly I through the opening 12. The'products of combustion will pass upwardly between the'` bafHes, .being compelled'to follow atortuous i path. These baffles willprevent theflame from entering the outlet 3 and will absorb i' much of the'hea't escaping upwardly. This" heat will be conducted through Vthe baffles to the vwalls of the structure and radiate'therefrom, thus increasing the eiliciency.l of the heater. By leaving the doors13 closed there 7 is no danger of sparks iying` forwardly through the opening and igniting articles in close proximity to thevhousing.

It is to be understood of course that this structure can. be suitably ornamented and in The baiies can be fcleanedreadily lby shifthousing.
