WILLIAM H. CAIN, OF LOS ANGELES, CALIFORNIA.

GAS RADIATOR.

Application filed June 20, 1921. Serial No. 479,150;

To all whom it may concern:

Be it known that I, WILLIAM H. CAIN, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented new and useful Improvements in Gas Radiators, of which the following is a specification.

This invention is a radiator particularly adapted to be employed as a hot air radiator in which a usual gas burner is employed as the heating means. The radiator provides for the passage of the hot air through the various sections of the radiator by way of updraft flues, down draft flues, and up draft flues. These final up draft flues communicate and lead to a common discharge flue formed in the central section of the radi= ator. By this arrangement it will be noted.

that there is adequate circulation of the heated air to cause efficient functioning of the radiator.

The invention will be readily understood from the following description of the accompanying drawing, in which:

Figure 1 is a side elevation of a radiator constructed in accordance with the invention.

Figs. 2 and 3 are transverse sections on the lines 2-2 and 3-3 of Fig. 1.

Fig. 4 is a horizontal section on the line 4 4 of Fig. 1.

Figures 5 and 6 are vertical sectional views taken on the lines 55 and 6-76 respectively of Figure 3,

Figure 7 is a transverse sectional View taken on the line 7-7 of Figure 3.

The radiator comprises ahase chamber 1 supported upon suitable legs 2 and adapted to receive a usual gas burner 3 which extends the length of said chamber, Air is admitted to this chamber through suitable ports 4.

The upper surface of chamber 1 is provided with openings for the radiator flues, and said openings are arranged in series lengthwise of chamber 1 and having three openings in each of said series transversely spaced across the chamber. Flues 6 extend upwardly from the respective openings in the tube of chamber 1, and the three transversely arranged flues of each series are connected by a header 7 in order to form the respective sections of the radiator spaced along the length of the same. i

A partition 9 is arranged in each header 7 so that the flues A communicating with the headers at one side of the same are shut off from the other two flues B and Ccommunicating with the, headers, and these latter two flues communicating with each header also communicate with each other by way the headers.

The portions 10 of, the headers beyond partitions 9 and with which the single flues- A communicate, in turn communicate with one another by way of ports 11, andconnecting nipples 12 project from the headers and connect with one another when the sections of the radiator are assembled.

The flues B which are the outside flues of theflues B and C communicate directly with chamber 1, while-the'lower end of each flue C communicates with one of the chambers 13 formed in chamber 1 by means of a horizontal partition 141 and a vertical partition 14;. These partitions are so arranged as to close the chambers 13 to the chamber 1 while affording communication from the respective flues C through the chambers 13,

and thence into the respective flues A. By this arrangement it will be seen that the air heated in chamber 1 will circulate upwardlythrough flues B, thence downwardly through flues C, and then upwardly through flues A and outwardly through ports 11.

One section of the radiator, which in the present'instance is shown as the center section, is arranged to receive the heated air from the other sections and through. the ports 11 of said section. then discharged through said center section of the radiator.

' Asan instance of this arrangement a partition 15 is arranged in this discharge section of the radiator and is positioned acrossthe chamber 1 ofsaid section so as to form adischarge chamber 16 which is a longitudinal continuation of the flue A of said section. It will be understood that this discharge chamber is closed toboth chambers 1 and 13, A discharge port 17 opensfrom the discharge chamber 16 and is connected to any suitable outlet flue. The discharge chamber 16 is preferably also provided with a base opening 18 for the discharge of any air which may be blown back through outlet flue 17 into the radiator.

In order to provide for the continued circulation of the hot air passing through the discharge section of the radiator, and after it enters the chamber 13 from flue C, this latter chamber is provided with a by-pass The heated air is.

port 20-at one side and with a by-pass port 21 at the other side in the chamber 13, as clearly shown in Figs. 2 and 3. By this arrangement the heated air entering chamber 13 of the discharge section of the radiator will pass by way of ports 20-2l into chamber 13 of the adjacent section of the radiator, and thence upwardly through flue A of this latter section so as to be discharged, as pre viously described.

The construction as thus set forth forms an extremely compact and practical radiator in which circulation of the air is caused by way of up draft flues, down draft 'flues, and up draft flues. The radiator structure also provides for the discharge of the heated air from the various radiator sections through the final flue of one of the radiator sections, which in this case is utilized as a down draft flue. In this discharge section of the radiator the circulation of the heated air is by way of the up draft flue, the down draft flue, and thence back to one of the other sections of the radiator so as to finally flow through the final up draft flue of the latter.

Various changes may be made without departing from the spirit of the invention as claimed.

What is claimed is: p

1. A radiator comprising a pluralityof headers divided to form communicating chambers and communicating portions, a

base formed to provide a combustion cham her and connecting chambers, up draft flues forming communication between the communicating chambers and the combustion chamber, down draft fiues forming communication between the communicating chambers and the connecting chambers, a second set of up draft flues formingcommunication between the connecting chambers and the communicating portions, an outlet chamber formed in the base and communicating with one of the up draft fines of the second set, and by-passes around. the last mentioned flue.

2. A radiator comprising a base having a heating chamber adapted'for the reception of a burner, flues supported on the base and arranged in sets including two outside sets and an inside set, headers on the flues, and partitions and openings in the base and headers for causing the heat in saidheating chamber to circulate up one outside set of flues, down the inside set of fiues, up all of the other outside set of flues except one, and finally down the remaining flue through the last mentioned set to a point exteriorly of the radiator.

3. A radiator comprising a set of flues, a second set of flues communicating with the first set, a third set of flues communicating with the second set of flues, and a discharge flue common to all of the flues of the third set.

4:. A radiator comprising up draft flues, down draft flucs, and a down draft discharge flue common to certain of the up draft flues.

5. A radiator comprising up draft flues, down draft flues, and a down draft discharge flue common to certain of the up draft flues and disposed medially thereof.

6. A radiator comprising a set of up draft flues, a set of down draft flues communicating with the first flues, a second set-of up draft flues communicating with the down draft flues, and a discharge flue common to all of the up draft flues of the second set.

all of the up draft flues of the second set,

and disposed medially thereof.

9. A radiator comprising a base having a heating chamber adapted for the reception of a burner, flues, supported on the base and arranged in three sets, headers on the flues, and partitions and openings in the base and headers for causing the heat in said heating chamber to circulate in one direction through one set of flues, in another direction through another set of flues, in the same direction through all of the third set of flues as the first set except one, and finally through the remaining flue of the last mentioned set to a point exteriorly of the radiator.

In testimony whereof I have signed my name to this specification.

WILLIAM H. CAIN.
