fl-r' i V v GAS RADIATOR. 'Y .Y-Y"

Application filed August 11, 1921.A Seria-TND. 491,377;

To @ZZ whom t may concern:

Be it known that LoDAvn.) M. BoWnN, a citizen of the United States.y residing at Los Angeles, in the county of Los Angeles and State of- California, have invented a new and useful Gas Radiator, of which the fol lowing is a specication.

My. invention relates to the art of heating and more particularlyto a gas radiator.' a

One of the objects of my invention 1s to produce a gas radiator that will give the maximum of efficiency at a verylow cost.

Another object of my invention is to` produce a radiator of simpleform and construc-k tion whichiwill heat'and Vcirculate the surrounding air without discharging any of the products yof combustion into the room.

Another object of my invention is to produce a radiator of the classfdescribed which draws its lsupply of combustible air` from the outside atmosphere.

Referring to the drawing which -is for illustrative purposes only, l

f Figure 1 is a perspective view of my improved gas radiator. l l I .Fg 2 is a vertical sectional view on; line 2 2, Fig. 1, andl 1 .F ig. 3 is' a cross section on line 3 3, Fig. 2 v I i Like reference numerals correspond to like partsthroughout the several views. v y

V.The radiator .consists generallyfof side members or columns'll and 12, a combus-Q tion chamber13, a top 14, heat ,transfer flues 15 and legs 16.'z ,i l l .f

lThe combustion chamber 13forms the bot'- tom of the radiator and is provided with` a burner 20 having gas tips'21. Gras is supplied to the burner 20 from any convenient source by a pipe 23, the amount required being regulated by a valve 24. Air is supplied to the burner by a pipe 26 which passes through the floor of the room in which the radiator is placed. One end of the pipe 26 is open to the outside air, the other being connected to an air manifold 28 secured to the bottomV 29 of the combustion chamber. 30 designates openings in the bottom 29 of the combustion chamber through which the air from the manifold 28 passes to the combustion chamber 13.

The sides or columns 11 and 12 of the radiator are composed of hollow rectangular sheet metal members. The inner face 35 of each member is punched to receive the the radiator.y

`through the neXt flue, passing back and forth specification of Leftersratentf Patented Ap1n25, 1922.

ends of hollow rectangular flues These Vflues arejspaced apart from one another by spaces 36 andare angularly disposed for reasons lnreinafterV set forth. Battles 38` are provided on the inside of the columns 11 and 12 between yalternate Hue openings to course the products of combus-` tion and hot gases in their passage through The inside .of the combustion chamber 13v andv the burneiyareaccessible through an opening l 39 `in the front ofv the radiator. This opening is provided with a door.40. An opening41 in. the-top 42 ofithevcombustion chamber 13 allows ythe products of combustion vand hot gases to enter vthe column 12 of the radiator.' Theftop 42 is angularly disposed to conform to theangularityofcthe' flues 15. Y

The top 14 ofthe `radiator isf a hollow rectangular member provided on the rear wall 44y with-an outlet45 which ,connects with a pipe 46 for carrying the-productspf combustion to, theoutsidefair. The-bottom 47 f; is angularly disposedtofconform to the fan-1 80 gularity `of the fflue'sV 15..,v

,'The operation of my improved radiator isk as follows: f y i The products of combustion and heated air from',y the combustion chamber pass through the opening 41vintoth`e column 12 of the :radiatoriwhere they strike-thefrst battle 38which deflectsfthe course -ofvthegases into and th'roughfthe vlowest fine '15 thence into the,` other,.columnV 11-of the radiator wherefthey vare ,again deflected by af baffle 38 into and through .the neXtflue 15 back to the column 12 l above Vthe'ffirst baiiie, where they strike another baiiie 38( and are deiiected' from side to side of theradiator until they reach the top 14 from whichthey pass into the pipe 46 tothe outer air.

During the time the products yof combustion and hot gases are passing from the combustion chamber back and forth through the flues 15 to the top 14, air in the room is being heated by circulating through the radiator- Y between the lues in the direction of the arrows, Fig. 3. This circulation is caused by the angular disposition of the flues 15. The heated air between the fluesl in. trying to escape pass upwardly against the lower side of the fluesi 15, the upward tipping ofy each flue causing a forward movement of the air. 110

' said combustion chamber, the wall between lt will be noted that by the time the products of combustion and hotgases pass from the combustion chamber back and forth in their zig-zag course through the -fl-ues A1,5 to the top 14, most Vof theheat has been transferred to the air surrounding the radiator and practically all stack losses ofheat are eliminated, thus producing a very high eiliciency heating unit.

l/Vhat I claim and desire to secure Vby Letters Patent is: l

l. A radiator comprising walls forming a combustion chamber; legs supporting said combustion chamber on but slightly above a floor; walls forming an air manifold below said combustion chamber, the vwall between said air manifold and said combustion chamber being perforated to allow airrto pass therethrough; a pipe connected into said air manifold and extending downwardly through said floor; a gas burner in said combustion chamber; two hollow rectangular sheet metal columns, one situated above each end of vsaidwcombustion chamber, one of said columns being in 013GB Communication with said chamber; a series of sheet metal fluesy each extending between said' columns and communicating at either end with the linterior of said Columns; baffles in said columns so disposed that the gases rising from said combustion chamber Vpass successively through said i'lues: a hollow top for said radiator so formed that the hot gasesr from one of said columns is discharged thereinto; and an outlet flue connecting the interior of said top with a chimney.

2. A radiator comprising walls forming a combu'stionchamber; legsY supporting said combustion chamber on but slightly above a floor; lwalls forming an air manifold below said-air 4manifold and said combustion chamberbeingl perforated to allow Vair to Ypass therethrough; a pipe connected int-o said air manifold and` extending downwardly throUgh,v said floor; a gas burner in said combustioii chamber; two hollow rectangular sheet metal columns, one situated above each end of said combustion chambenone of said columns being in open communication with said chamber; a series of sheet metal (lues each extending between said columns and communicating at either end with the interior of said columns, each of said flues having fiat sides extending substantially across the whole width of said columns and inclined to the horizontal; baffles in said columns so dis-H combustion chamber on but slightly above a floor; walls forming an air manifold below said combustion chamber, the wall between said air manifold and said combustion chamber being perforated .to allow air to-pass therethrough; a pipe connected into said air manifold and extending downwardly through said floor; a gas burner in said combustion chamber; two hollow rectangular sheet metal columns, one situated above each end of said combustion chamber, kone of said columns being in open communication withsaid chamber; a series of sheetI metal flues, each extending between said columns and communicating at either end with ,the interior ofI said columns, each lof said iues having flat sides extending substantially across" the whole width of said columns and inclined to` the horizontal; baffles lin Vsaid columns so disposed that the gases rising from said combustion chamber ,passn successively through said flues; a hollow top for said radiator so formed that the hotgases from one of said columnsv is discharged thereinto; and an outlet flue connectedfto that side of said top which is above the lower end of said inclined fines.

In testimony whereof, I have hereunto set DAVID M; BOWEN.
