FURNACE.
This invention rela-tes `generally-to -f-ur naces' which are used for heating the `\atmosphere in dwellings and living quarters, and particularlyv to furnaces for heating air, or water, or both. p
The "first object of this invention lis to provide an exceedingly vsimple and efficient furnace which will `be easy to manufacture, not easily damaged b y heat or transportation and very simple to set Iup and `keep `in .first class condition. f
The second object is to provide heavy metalhorizontal tu'besfof1 any desi-red shape, in which the airis heatedand delivered jto the supply pipes branching out to the various rooms.
These, and otherobjects, will become Amore apparent from the specification following` as illustra-ted in the accompanying drawings, in which:
Figure .1 is a longitudinal vertical section through the device taken along the line 1-.-1 in Figure 2. 'Figure 2 Visa transverse section taken 4along the line 2-2 Vin Figure 1.. Figure 3 is a front elevation. Figure lis a horizontal section ytaken along the lline 4;-4 in Figure f1. Figure 5 is an enlarged plan of the shaking-end of a portion ofthe grate bars. `Figure 6 is a section taken along the line 6;-6 in Figure 5. Figure 7 is fa lsection takenA along the vline 7-7 in'Figure 5. Figure 8 is a fragmentary enlarged plan of a sectionof the shaker bar or channel .iron through Ywhich the shaker arms Y pass. Figure 9 is a section taken valong the line 94-9 in Figure 8.
Similar numbers of reference refer to the same parts throughout the several views.
Referring in detail to the drawings, the furnace is illustrated in its preferred form with cast inner parts anda sheet metal outer casing, although this eXact construction'l need not be followed, it being merely illustrated as one of the ways in which this furnace can be constructed.
In the drawings arershown a base 10 having la floor 11,7inturned flanges 12, upper flanges 13 and a back 14, while across the frame 15 is secured an ash pit door 16 provided with a draft door 17 on the hinges 18. On the base 10, which forms the ash pit of the furnace, is placed a fire pot wall 19, y
preferably lined with fire brick 20. lGrate bars 21 form the floor forthefire pot and journalirn y.the grateba-r Vframe 22,l which rests on the flanges 12 under the Iflanges 13. `On the Shanks 23 of the grate bars 21 are placed thelevers 24 vwhose lower endspass through the channel iron 25. iron 25l is provided with slots 26 'adapted to receive ythe lowerends of the=levers124t` which *.aresecured on the Shanks 2 3 of the grate bars 21. The channel iron 25 rests on the out-turned flange of ythe Lgrate Vbar fraaie` 22. A ledge 28 is formed around the upper side'of the lflange 13 andv servesto held the lire brick 20 in place. y.
',Overthe fire, pot is placed a lbody `whose sides 29 are shown as'castand having joutturned flanges 30 formed thereon and having lrecesses 31 formed therein. l
One end of each tube A32 ,projects just.
through thefo'utsideof a flange 30. and the other end of Ithe tube 32 `proj ects `through the opposite `flange30 andv through anopening in the outer side of thefurnace and connects with the elbows 33, from which the pipes may be led to the'various rooms. f
Vlihen the side-frames 29 ofthe body are made of j steel, the tubes 32 are preferably welded to the side frames thereby insuring an` absolutely tight joint against s1noke,for
The channel y else provided with a draw band .(not,
shown), under` whichfis A placed `suitable peeking.
When a tions which require fewer air ducts than it possesses flanges 30, it is only necessary tov cap the end of the tube, or, if desired, omit the tube altogether and cap the flanges 30.V
provided a flanged opening 38 to `which may furnace is installed under condibe attached' the smoke pip-e 39. On top of the body is placed an auxiliary body 1&0, across which is placed the transverse tubes 41 on whose projecting ends are placed th-e caps 42 from which may be led the pipes 43 connected with the usual hot water system. The auxiliary body is provided with a cover 44.
Over the sides ofthe parts just described, and spaced therefrom, are the casing walls 45y and across th-e rear is plac-ed a wall 46 pro-vided with a cold air return duct 47, which maybe in any convenient place.v
A damper 48 is placed at the rear of the body just in front of the smoke outlet 38, and a rod 49, which passes through the front of the furnace, is attach-ed to the upper side of the damper between the nuts 50. A sheet metal front 51 forms the front of the furnace casing not occupied by the door frames.
A sand pan is formed by the casing cover 52 whose up-turned edges 53 are secured to the side walls of the casing. f
The operation of this device is as follows: Fuel is placed on the grate bars 21 and the draft door 17 is opened, as well as the damper 48, which is swung to the position shown in full lines in Figure l. The draft is then directly through the pipe 39. lWhen the lire is sufficiently started, the damper 4S is moved to the position shown in dotted lines in Figure l and vthe drafty 17 is checked. The heat nonT circulates laround the tubes 32 and warms the air within same discharging it through the elbows 33, Land takes in more air from within the casing, which air has just enter-ed the intake pipe 47 and absorbed heat which is radiated from the sides of the ash pit, fire pot` and body.
If it is desir-ed to heat a portion of the house with hot water, or to provide a supply of hot water for domestic purposes, the unit 40 is employed, which, of course, operates in the same manner as the air unit except that both ends of th-e tubes 4l project from the casing walls 45. If it is not desired to ein-v ploythe water unit, a cover is placed directly over the air unit in place of the cover 44. i
With the construction above outlined the cleaning process is entirely eliminated, since there is no place for soot or ashes to lodge.
It must be understood that many changes fore do not intend to cover such devices broadly but I do intend to cover all such forms and modications as fall fairly Within the appended claims.
I claim:
1.*A furnace having, in combination, a combustion chamber; a casing around said combustion chamber; and horizontal flues passingthrough sai-d combustion chamber and having one end opening into the space between said casing and combustion chamber and the other end passing through said casing and connecting with a warm air con? ducting pipe.
2. A furnace having, in combination, an ash pit; a lire pot over said ash pit; a body over said fire pot;l an air-containing casing around said ash pit, fire pot and body; a plurality of horizontal flues passing through said body, one end of each flue passing through said casing and the other end of said iue opening into the space'b-etween said bod and casing.
3. A urnace having, in combination, an ash pit; a tire pot over said ash pit; a body over said fire pot; a cover over said body; a smoke pipe leading from said body; a casing aroundv said ash pit, fire pot an-d body; a plurality of horizontal warm air delivery tubes passing through said body and casing and opening at one end `into the space between said body and casing; and a damper between said tubes and said smoke pipe opening.
