UNITED STATES WILLIAM H. GAIN, OF LOS ANGELES, CALIFORNIA.

GAS-RADIATOR.

Specification of Letters Patent.

Patented May 20, 1919.

Application filed April 1, 1918. Serial No. 226,090.

T0 all whom t may concern:

Be it known that I, WILLIAM H. GAIN, 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 Gras-Radiators, of which the following is a speciiication.

My object is to make an ,improved gas radiator and my invention consists in the novel features herein. shown, described and claimed.

Figure 1 is a front elevation of a gas radiator embodying the principles of my invention, the view being taken looking in the direction indicated by the arrows 1 in Figs. 2, 3, 4 and 5, parts being broken away and shown in section.

Fig. 2 is a side elevation looking in the direction indicated by the arrows 2 in Figs. 1, 4 and 5.

Fig. 3 is a vertical cross-section on a plane parallel with Fig. 2 and on the lines 3 3 of Figs. 1 and 4.-.

Fig. 4: is a horizontal section on the lines 4.-4: of Figs. 1, 2 and 3.

Fig. 5 is a staggered horizon-tal section on the lines 5 5 ofFigs. 1, 2 and 3.

Fig. 6 is a fragmentary vertical longitudinal section on the line 6 6 of Fig. 3'.

Broadly, my improved radiator comprises a supporting section 1, a burner section 2 secured to the bottom of the supporting section 1, intermediate sections 3 extending upwardly from the supporting section, and a cap section 4t on top of the intermediate sections 3.

The supporting section 1 comprises a bottom 5 havinggaJ longitudinal burner opening 6, legs 7 extending downwardly from the four corners ofthe bottom, a front wall 8 extending upwardly from the bottom, a rear wall 9 extending upwardly'from the bottom, end walls 10 and 11 connecting the front and rear walls and extending upwardly from the bottom, a top wall 12 connecting the upper edges of the walls 8, 9, 10 and 11 and having a series of front flue openings 13, a series of rear flue openings 14:, and a baflie wall 16 extending downwardly from the top and forwardly to the front, there being a by-pass opening 15 leading downwardly from the center of the bathe to near the bottom, thus forming a combustion chamber 17, said by-pass opening 15 communicating with the combustion chamber above the bottom 5 and there being lighting openings 18 through the wall 8. Y

The details of the intermediate sections 3 are as follows: In the radiator shown I have imitated a live-section steam radiator, there being five up-draft flues 19, the lower ends of the tlues resting upon the top 12 around the openings 13, and vthere are four down-draft iues 2O resting upon the top 12 around the openings 14, and a center outlet flue 21 resting upon the top 12 above the by-pass opening 15. The front and rear walls 8 and 9 have undulations 22 and 23 extending between the flues, there being bolt'ng flanges 24 and 25 across the tops ofthe undulations. A stove pipe nipple 26 leads laterally from the outlet flue 21. A vpipe 27 is mounted through adjacent walls of the flue 21 and the center oneof the dues 19, the discharge end of said pipe being centrally located in the stove pipe nipple 26, and a flaring elbow 28 extends downwardly from the end of the pipe 27 in the center flue 19, so that hotl air passing upwardly` from the combustion chamber 17 will be collected by the open end of the elbow 28 and discharged through the pipe 27 to the stove pipe nipple 26 to start the draft, said pipe 27 and elbow 28 thereby serving as an injector.

The details of the cap section 4 are as follows: A rectangular horizontal plate 29 has a front row of iue openings 30 corresponding to the openings 13, a center rear web 31 closing the upper end of the flue 21, and rear return flue openings 32 corresponding to the openings 14, there being beads 33 extending downwardly from all the openings 30, 31 and 32 and beads 34 extending upwardly around all the openings 13, 14C-'and 15, and the ues 19, 20 and 21 itbetween the cap and the supporting section withinthebeads. Return bends 35 extendupwardly from the plate 29 crosswise of the plate so as to connect the front flues 19 `with the rear flues 20, there being openings 36 connecting the return bends together sidewise, so that the center bend which strikes the web 31 may discharge laterally to the rear flues 20. Flanges 37 and 38 are thus left between the ends of the return bends, and rods 39 and 40 connect the flanges 24 and 25 to the flanges 37 and 38 so as to hold the cap section 4 on top of the intermediate sections 3 and the intermediate sections 3 upon the supporting section 1.

The details of the burner section 2 are as follows; A rectangular plate 41A fits upl wardly against the bottom 5 to cover the opening 6 and is secured in place by bolts 42. Burner heads 43 are screwed downwardly through the plate 41 in a row at the transverse center of the radiator and extending from end to end, there being preferably eight burner heads for the five sections of the radiator. The burner base 44 extends downwardly from the plate 41 and has a chamber.

45 communicating with all the burner heads 43. The mixing tube 46 is elbow-shaped and is screwed upwardly into the bottom of the base 44 preferably at its longitudinal center. The gas cock 47 carrying a gas nozzle is screwed into the end of the mixing tube 46, and the gas pipe 4S leads to the gas cock. `ijerforations 49 are formed through the plate 41 along the sides of the base 44 to supply air to the combustion chamber 17 around the burner heads 43. The chamber 50 extends the entire length of the radiator on the back side under the top 12 and between the baffle 16 and the rear wall 9, and the by-pass 15 leads downwardly from the center of this chamber.

In the practical operation, a lighted match or taper is inserted through one of the lightin g openings 1S, the gas cock 47 manipulated to turn on the gas, and the gas burns from the burner heads 43 in the combustion chamber 17, and immediately the rush of hot air upwardly will start the injector, consisting of the pipe :27 and the elbow 2S, to start the draft up theV stove pipe leading from the stove pipe nipple 26. Continued operation will cause the hot products of combustion to pass upwardly through the iiues 19 to the return bends 35 and downwardly through the flues 2O to the ends of the chamber 50 between the baffle 16 and the rear wall 9, then upwardly from the center of the chamber 50 to the iue Q1 and outwardly through the pipe nipple 26 and up the stove pipe or chimney. rThis tortuous circulation will heat a large amount of radiating surface and at the same time requires a steady draft from the stove pipe or chimney, and when the draft is unsteady, and especially when there is a back-draft, there has heretofore been a liability of extinguishing the flames from the burners and I have found by much experimenting that by providing the by-pass opening lleading downwardly from the chamber 50 to the bottom of the combustion chamber I avoid the liability of putting out the fire. A sudden gust of wind blowing the v products of combustion backwardly down the Vflue will cause compression in the flue 21, forcing the draft downwardly through theby-pass 15, thereby stimulating the circulation within the radiator instead of retarding it. This communicating chamber 50 collecting the products of combustion from the flues together with the by-pass opening 15 is of ygreat importance.

Various changes may be made in the details of construction without departing from the spirit of my invention as claimed.

I claim:

1. A radiator comprising a supporting sec tion, intermediate flue sections upon the supporting section, anda cap section upon the flue sections; thus forming a combustion chamber, a connecting chamber, iiue passages leading upwardly from the combustion chamber and down to the connecting chamber, a flue leading upwardly from the connecting chamber, and a bypass leading downwardly'from the Vflue to near the bottom ofthecombustion chamber. Y

2. vA radiator comprising a supporting secA tion, intermediate line sections upon the supporting section, and a cap section upon the flue sections; thus forming a combustion chamber, a connecting chamber, flue passages leading up from the combustion chamber and down to the connecting chamber, a blind flue leading upwardly from the center of the connecting chamber, an outlet below the-upper end of the blind liuc, and a bypassleading downwardly from the bottom of the flue to near the bottom of the combustion chamber.

3. In a radiator, means forming a combustion chamber and -a connecting chamber, means forming line passages Leading .up from the combustion chamber and down to the connecting chamber, and a flue leading upwardlyfrom the center of the connecting chamber; there being a bypass leading downwardly from the bottom -of the flue to near the bottom of the combustion chamber.

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