This invention relates to improvements in warm air heating furnaces. j
The object of the invention is to provide such a furnace with improved construction of sheet metal radiator for heating the warm air within the furnace casing.
Objects pertaining to details and economies of construction and operation will definitely appear from the' descriptiond to follow. A
0 furnace embodying the features of my invention is illustrated in the accompanying drawin ,in which:
ig. 1 is a vertical central sectional elevation of a furnaceand casing embodying my improvements, taken on line 1-1 of Fig. 2.
Fig. 2 is a horizontal section taken on irregular line 2-2 of Fig. Al.
The parts will be identified by their numerals of reference which are the same in all the views. y l
1 is the ash pit base. 2 is the firepot. 3 is the combustion chamber made up of su )lerimposed rings with a dome 4, the rings bing joined together by joints comprising annular grooves in the top of each ring receiving the lower edge of the superimposed-ring or dome. :o 5 is the furnace casing having the usual top G.
The dome 4 is provided with an outlet pipe 4l.
My improved radiator 7 is annular in form and is made of sheet metal having a vertical outer Wall 71 and an inturned bottom wall 72 5', extending in a downturned flange 7 2 adapted to project into the top groove of the lower at the smoke pipe 8.
A usual clean-out 77 is provided.
The high eiiiciency ofthe device is due to its broad radiating surface and free circulation. No direct draft is necessary and I consequently do not pr ovide one. The flow of cj the heated products of combustion is very free through my imp of the broad surfa'c given up, resulting thin sheet metal is a very effective means of roved radiator. Because e the heat is very fully in high etciency. The
transferring the heat. l
I produce my improved-radiator from sheet steel and weld the edges thereof together. To accomplish the results to the best advantage I install the same parts, cal inner wall 74 an on the furnace in two divided at the joint between the vertid the to wall 7 3 which are held temporarily in p ace. When the structure is installed and the joints fully formed with the combustion chamber, I weld this last'joint by torch or electric weld, maklng a complete tight structure. The structure, being of sheet metal, is comparatively inexpensive to produce and, while it is made of very thin metal,
delivers its heat very rapidly and is consequently subject to unusual erosion it can be very readily renewed and the structure is even I desire to claim then very economical.
it in the specic form shown and also broadly as pointed out in the c5 appended claims.
combustion chamber ring, sce Fig. 3, where\\ Having thus descrlbed .ny invention, what the same is secured by suitable cement such as Smoothon, the same being merely pow- 40 dered iron.
The top wall 7 3 is flat and is welded to the vertical inner .wall 74 which extends vertically downward straight into the 'top joint groove of the top ring of the combustion 43 chamber. The inner wall 74 is suitably perforated at 7 5 for accommodation of the smoke pipe sleeve 41. The smoke pipe sleeve 8 is secured to` the outer wall 71 and delivers through the outer casing 5 to the chimney. i 5'.)
wardly therefrom, A vertical partition wall 76 is between thev I claim as new and. ters Patent, is:
1. In a hot air furnace, the combination desire to secure by Letwith a firepot and combustion chamber made up of ring sections having joints comprising grooved top edges engaging the lower rim of the adjacent ring, of a dome therefor with smoke outlet pipe,
an annular sheet metal 55 heat radiator surrounding the top of the said combustion chamber and formed of an outer annular wall, a bottom wall extending in-` taching ange secure and terminating in an atd` in the top groove of the lsu combustion chamber top ring, a top wall, and an inner annular wall connected tothe top wall and extending downwardly into the joint groove of the top ring of the combustion chamber, said combustion chamber being apertured for the smoke pipe from the done and being provided witha smoke pipe sleeve and having a vertical partition between the said smoke combustion in the radiator.
2. In a hot air furnace, the combination with a firepot and combustion chamber made up of ring sections having joints comprising grooved top edges engaging the lower rim of the adjacent ring, of a' dome therefor with smoke outlet pipe, an annular sheet meta-1 heat radiator surrounding the dome of the said combustion chamber and formed of an outer annular Wall, a bottom wall extending linwardly thererom,a top wall, and an inner annular` wall connected to the top wall and extending downwards carried by the wall of the combustion chamber, said combustion chamber being connected by a smoke pipe out- A dome and being provided with. 'a smoke pipe sleeveprojecting from the ralet from the diator and having a vertica partition be- -tween the said smoke pipe sleeve and the smoke pipe outlettto insure iow of of combustion in theradiator.
In witness whereof lI have hereunto set my hand.
JOHN WINTER.
