i HEATINGfSTQV-E To all whom it may concern Be it known that I, JAMES McDoNALD- a stove of this character which will be simple in construction and effective in operation and in which the heated air is discharged near the floor.

With the above and other objects in view, the invention resides in certain novel features of construction and combination herein described and claimed and shown in the drawings wherein- Figure 1 is a front elevation of my improved stove; Fig. 2 is a plan view thereof; Fig. 8 is a vertical section; and Fig. 4 is a detail side elevation of the flue which is employed for conducting the heat and discharging it near the floor.

In the accompanying drawings, I have shown my improved stove as comprising a cylindrical shell 1 whose bottom 2 is provided with a plurality of draft openings 3 while its top 4 has an opening 5 which is surrounded by an upstanding flange 6 over which a flange 7 depending from a cylindrical heating drum 8 is normally seated thus forming aheat passage from the shell 1 into the drum 8. The top of the drum 8 is provided with a heat conducting opening 9 surrounded by an upstanding flange 10 for a purpose to appear. Mounted inany suitable manner within the lower end of the shell 1 is a burner B over which is disposed a hollow frusto-conically shaped element 11 which as shown, is perforated and is supported by suitable legs 12 resting upon the bottom 2. Supported in the drum 8 and in the shell 1, are upper and lower heat retarding and radiating plates 14: and 15, said plates being concavo-convex in cross section and having their convex faces turned downwardly. The plate 15 is supported by a suitable ledge 13 secured to the inner face sps fi L t PatentedDec. 1551914. :Application filed January 19,1 14.- Serial No. 812,970. l

the shell 1'. Itemovably seated over the flange 10 of the drum 8 is a similar flange 16 depending from a lateral arm 17 of a heat conducting pipe'18 which extends downwardly in contact with the shell 1 and is provided with a lateral-1y extending heat discharge casing 19 in the front of which an elongated opening 20 is formed.

WVith the parts disposed as above described, theburner B being lighted, the

flames therefrom will heat the element 11 to a very high temperature and the heated air will then rise and be deflected outwardly into contact with the wall of the shell 1.. This heated air will rise still further into the heating drum 8 where it will again be retarded and deflected outwardly and then allowed to escape through the pipe 18 and be discharged from the opening 20 near the floor upon which. the stove rests. Thus it will be seen that, although a great deal of heat is discharged from the sides and top of the shell 1 and the various faces of the drum 8, the heated air will be conducted to the floor in the above described manner.

This I considera very important feature of I my invention since, with most stoves of this character, all of the heated air is allowed to rise and practically none of it reaches the floor level. During the burning of the flame from the burner B, should any gases be exhausted therefrom, the element 11, which as stated-has been heated to a very high temperature, will immediately consume said gases and thus none of them will be discharged into the room. By the specific mounting of the flange 16 over the flange 10, the entire pipe for conducting heated air to the floor may be removed for cleaning or other purposes.

Although I have described my invention with considerable minuteness, I do not Wish to be limited to details other than those amplified in the appended claims.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is 1. A stove of the class described comprising a hollow shell having a draft opening in its bottom and a heat discharge opening in its top, a burner in said shell, a heating drum removably mounted on the top of said shell and having a bottom opening registering with the opening in the shell druni and shell and extending tfansversely thereof and a hot air conducting pipe removably engaged with saiddrum over the top opehingtherein and extending downwardly outside said drum and shell and diseharging near the; lower end of the latter.

' i '2. A stove of the class described compris ing a hollow shell having a 'draftopening in its bottom and a, heat discharge opening in its top, aburner in said shell, 2
