Application sie@ August 9, 192i. serial no. 490,990. y
To all `whom it may concern.'
' Beit known that I, BENJAMIN F.' CALD- vWELL, a citizen ofthe' United States, residing to hang` floor furnaces, the said furnace thus being designed primarily for use on the upper {ioors of buildings where a `furnace hanging in the floor would give an unsightly appearance to the room thcrebelow. The
furnace is4 also 'to be used'wher'e there is a concrete floor near the ground so thatitis rendered convenient and advisable to place the `furnace above the floor level.
Another object is to provide a furnace designed to take the place of a radiator or a stove such as often used in a room, the present device, however, having the additional advantage vof providing fresh warmed air to the room and avoiding the unhealthy process of heating used, devitalized or foul air, the furnace also serving to keep all products ot' combustion out of the room so that therer vis no danger such as results from the escape ot gases into a room.
Another object is to simplify and otherwise improve upon the construction of ur nace disclosed for example in my co-pending application No, 452,022 tiled March 14, 1921, thereby to adapt it for thepurposes hereinbeore mentioned.
lVith the toregoinfr and other objects inr view which will appear as the description proceeds, the invention resides in the combination and arrangement ot parts and in the details ot constructionhereinafter de` scribed and claimed, it being understood that, within the scope of what is claimed, changes in the precise embodiment of the invention shown can be made without depart` ing from the spirit of vthe invention.
In .the accompanying drawings the preferred forms of the invention have been shown.
In said drawings Figure 1 isa view partly in side elevation and partly in section of a furnace embodying the present improvements.
Figure 2 is a section on line 2 2, Fig ure 1.
Figure 3 is a section on line 3-3,lFig
ure 1.
Figure is a transverse section through the base portion of'a furnace having `anair inlet through the floor thereunder.
Referring to the figures by characterslot reference 1 designates the outercasing fof the furnace .which can be ofany desired con-y tour and proportions, this casing resting on 7 the floor F and being provided in its wallsi at the lower ends thereof with air inlet V openings 2 covered with suitable screens or grills 3. The top! of the casing, whichis indicated at ,has a plurality Lof air woutlets.. y j
Mounted within the lower portion of the casing and spacedr from vthe walls thereof is an elongatedhousing 6 provided with inwardly extending' flanges 6 supporting a plate 7 having an opening 8 in one end portion thereof. A box 8v having an open end, y
is inserted into one end of the casing land vhousing 6. This box supplies fresh air to the opening 8.' In this opening is Seated the `lower end ofa combustion tube v9 lin which is supported a'burner 10 :to which fuely is supplied throng apipe 11 extending into the box 8. A radiator 12 isinounted on the plate 7 and extends around and above the combustion tube but terminates belowl the top` l oi: the casing. This radiator' has a to-p plate 18 andniounted in thetop' pla-te are the upper ends of air -flues' 14' the lower ends ot which engage the platel7- Similar radiators 15 Aare mounted at intervals on the plate 7, each containinga-ir flues 16 extending longitudinally theretl'irough and they several radiators are connected near their upperfan'd lower ends .by gas `fluesV 17. Ari-outlet flue 18 extends from the last ra diator ot the group and through the adjacent wall of the casing 1 and constitutes an outlet for the spent products of combustion, it being understood that this outlet Hue can be extended through" a wall of the room or into an outlet pipe or stack.'
Those portions of the plate 7 between the radiators are provided with small openinos 19 whereby freshl air 'can` flow upwardly y iue 2O extends through one of the walls W of the room and through one wall of the casing 1 and of the-'housing 6, this flue openf Vator 12.
`through the lues 17 and heat them and then V,pass successively into ing into the housing close to and under the combustion tube 9'. A damper 21 is pivotally mounted in the upper portion oi the flue and has a weight 22 thereon for holding the damper' normally closed or in an inclined position across the lue. A cross. strip 23 is mounted within the housing 6 and has a longitudinal slot 24 in which ar pin 25 is slidably mounted. A link 26 connects this pin with the damper. Another link 27 eX- tends downwardly from the pin and is attached to one end of a chain 28 or other vflexible element extending under and upwardly from a guide sheave 29 mounted on vthe housing 6. A rod 60 may be attached to this chain and is" preferably i extendedthrough the topa of the casing 1,V it being understood -that this rod can ber supported "in'elevated 'position by any suitable means provided for that purpose.
When fuel is ignited at the burner 10 the v'combustion will be supported by fresh air 'entering box 6 and the hot products of com- V`bustion will'raise the temperature oi' the tube 9 to a high degree and said products of combustion will Ythen blow' around the tubes 14C so asto heat them and also heat the radi- Said products will then flow the other radiators which, with their fiues 16, willbe thoroughly heated. -Thus air entering the openings "2 will circulate between the casing 1 and the housing 6 Yand between the radiators and f 'will pass outwardly through the openings 5.
At the same time a certain amount of air from'the outside will enter the housing 6 by way of flue 20. l This air will flow upwardly f-through theiclues 1a and the openings 19 `Vand vthus be ythoroughly heated. @byiously by manipulatingthe damper 21 the amount` of air admitted to the housing 6 can be regulated and the heatingof the room can thus be controlled. f
f Instead of lhaving fresh air admitted to the housing 6jthrough one of its side walls yfa-nop'ening -31V can' be 'providedin the floor VvF where possible and as shown in Figure 1l. )Under these conditionsa weighted 'damper` "i 32 is pivotally mounted on the floor and is connected 'directly'by a chain 33 to a damper within and spaced i'r'oni the walls of the vcasn a combustion ytube extending upwardly from the housing, a fresh air boi(y projecting -into the housing and opening into the combustion tube7 a burner supported within Vthe combustion tube, Aradiators mounted von the housing and within and spaced from the casing, oney of said radiators enclosing the Vcoinluistion tube, air flues extending through the'radiators and communicating with the housing, and means for directing vfresh air intothe housing in controllable quantities.
2. A furnace including a casing having'Jr an air inlet and an air outlet adjacent the bottom and top` thereof respectively, ahousing within and spaced from the walls'of the casing, a combustion tube extending upwardly from the housing, a fresh air boXf VVprogecting into the housing and opening into the combustion tube,a burner supported within the combustion tube, 'radiators mounted on the housing andA within and spaced from the casing, one of said radia" tors enclosing the combustion tube, air ilues extending through the radiators and coinlinunicating with the housing, means .for directing fresh air into the housingin'controh lable quantities', and .lues connectingthe up Vper and lower portions of the radiators, lthere `being air outlets in the tcp of the hous- .ing and opening between the radiators. l .f
ln testimony that l claim the foregoing as my own, l have hereto azred my signa--` ture in the presenceof 'two witnesses.
