FURNACE RADIATOR Filed OCb. 6, 1950 Th mas r/lfk ATTORNEY.

Patented Jan. 23, 1934 FURNACE RADIATOR Thomas Crick, Independence, Mo., assigner to Independence Stove and Furnace Company, Independence, Mo., a corporation 'of Missouri Application October 6, 1930. SerialV No. 486,709 3 Claims. (Cl. 126-102) `My invention relates to radiators and more particularly to devices of that character for use in hot air furnaces, the principal objects of the invention being to provide a radiator of novel construction for adapting coal furnaces for the use of gas or oil, and increasing the heating emciency of the furnace.

In accomplishing these and other objects of my invention. I have provided improved-details of structure, the preferred form of which is illustrated in the accompanying drawing, wherein:

Fig. 1 is a perspective view of a furnace equipped with my improved radiator, parts being broken away for better illustration.

Fig. 2 is a sectional plan View of the radiator.

Fig. 3 is a fragmentary section of the top of the radiator illustrating the joint for the side and top wall members.

Referring in detail to the drawing:

1 designates a furnace of the conventional coalburning type herein shown converted for the use of gas, the iire box 2 being fitted with gas burners 3 and with my improved radiator 4 replacing the radiator normally used thereon for coal-burning purposes.

The radiator 4 is of the horseshoe type and in'- cludes a substantially semi-circular or arcuate casing having side walls 5 and 6 spaced-apart by end walls 7 and by top and bottom wall members 30 8 and 9 forming a chamber 10 for receiving heat from the iire box 2, the end walls 7 being spaced apart to provide an opening 11 whereby the radiator is adapted for fitting over inward projections on the front panel of the conventional type furnace.

Provided at the top and bottom ends of the side walls 5 and 6 are inturned and outturned flange portions 12 and 13 respectively, forming seats 14 engaged by peripheral anges 15 on the top and 40 bottom walls, the outturned portion 13 being lapped over the top and bottom walls at 16 for se- Y curing the members and forming an air-tight joint with the side walls.

Located in the inclosure 17 formed by the inner wall 6 is a manifold 18 including a hood p0rtion 19 for receiving heat from the iire box and having an open lower end 20 fitted with an adapter ring 21, whereby the manifold may be mounted over i'ire box openings of various sizes by the use of adapter rings having portions 22 to lit the top edge 23 of the re box.

Extending radially from the hood 19 of the manifold 18 in the form of an X'are conduits 24 and 25 for conducting heat from the hood 19 to the chamber 10. The conduits are clamped in fittings 26 on the inner wall 5, the conduits 24 Vcommunicating with the upper portion of the chamber 10 adjacent the end walls 7 and the conduits 25 communicating with the chamber in a horizontal plane with the conduits 24 and sub- 60 stantially mid-way between the conduits 24 and an outlet conduit 26. The conduit 26 communicates withA the lower portion of the chamber v10 and 'extends outwardly from the outer wall 5 diametrically opposite the opening 11 betweenthe 65 end walls 7 and is adapted for conducting the products of combustion from the chamber 10 after their passage through the retarding elements presently described.

Located in the chamber 10 on opposite sides of i0 of the radiator and which tend to retard iiow of heat from the chamber 10 to the outlet conduit 26'.

in order to further retard the ow of heat through the chamber 10, I provide baffle plates 29 which are secured in the chamber to the top B6' and side walls and between the conduits 24 and 25 and are spaced from the bottom wall 9 to form an opening 30 so that heat from the conduits 24 is directed downwardly in flowing toward the outlet conduit 26.

Located between the conduits 25 and outlet conduit 26 are bafe plates 31 secured to the top and side walls and spaced from the bottom wall 9 for directing the flow of heat downwardly, and located between the baffles 31 and outlet conduit 95 26 are plates 32 which are secured to the bottom and side walls and spaced-from the top wall for directing the iiow of heat upwardly and cooperating with the plates 29 and 31 and with the tubes 27 in forming a restricted and tortuous passage A100 for retarding now of heat through the heating chamber 10.

in using my improved radiator, the heat produced by combustion of gas or oil in the furnace flows into the manifold 19 and is thereby evenly 105 distributed to the heating chamber 10. The heated gases entering the chamber 10 are retarded in their iow to the outlet conduit 26 incidentally permitting thorough heating of the side walls and tubes 27 and causing upward move- 1'1"() ment of cold air through the furnace for contact with the heated side walls and tubes whereby the air is heated for distribution to the building to be heated.

From the foregoing it will be apparent that a furnace radiator constructed in accordance with my invention will permit coal-burning furnaces to be converted for the use of gas or oil at a minimum cost, and that the greater radiation and retarded flow of heat will eifect a considerable saving of fuel.

What I claim and desire to secure by Letter Patent is:

1. A radiator of the character described including an arcuate casing having inner and outer side walls and top and bottom walls forming a chamber, an outlet conduit opening through said outer side wall, an inlet manifold concentric with said casing and having branches opening through said inner side wall for conducting heated2 gases to said chamber, tubes extending through the chamlber and top andbottom walls, and baille plates fin the chamber interposed between said tubes and arranged to cause downward flow of gases into "said chamber upon issuing from each of said walls to form a chamber, an inlet manifold having branches communicating with said inlet openings for delivering products of combustion into said chamber, tubes extending through the chamber and top and bottom walls, and baille plates in the chamber interposed between said tubes and arranged to cause downward flow of said products of combustion upon issuing from each of said branches and a succeeding upward and downward flow of said products before passing through the outlet opening.

kfrom the outer wall and having inlet openings adjacent its ends and at points substantially midway between its ends and the outlet opening, topandbottom wallsconnecting said inner and 4`outer walls to form an arcuate chamber communicating with said outlet opening, an inlet Inaioifold having branches communicating with lsaid Ainlet openings for delivering products of combustion into said chamber, tubes extending let opening.
