GAS HEATER.

Application i'led .Tune 14, 1924. Serial No. 719,981.

To all lwhom t may concern:

Be it known that l, BnanToN F. Ronenus, a citizen of the United States, residing at Dallas, in the county of Dallas and State of Texas, have invented certain new and useful improvements in Gras Heaters, of which the following is a specification.

The present invention relates to a gas heater of simple construction and the main objectis to furnish a heater that will give complete combustion of the fuel.v

In view of the small space the heater will take in a room, it gives out considerable heat and as a matter of fact from extensive tests it has been found that the heater gives the service of an ordinar'y heater fully twice its size.

One of the advantages of the heater forining the subject-matter of the present invention is that it is very easy to keep clean and that no residues will collect around the same. The heater makes a very cheap lire, the flame being all blue and in sight of persons collected around the same. It has the additional advantage of directing the heat along the floor and the lower part of the room, or, in fact, no higher than the knees of the persons sitting in front of the heater.

In the accompanying drawings, one embodiment of the invention is illustrated, and

Figure 1 is a front elevation of the heater;

Fig. 2 is a vertical section on the line 2-2 of Fig. 1;

Fig. 3 is a side elevation of the heater as applied directly on a gas pipe;

Fig. 4l is a side elevation of the heater provi-ded with a flat reflector, and

Fig. 5 is a front elevation of the reflector seen in Fig. 3 with a wire guard attached.

In the drawings, the reference numeral 10 represents the base of the heater preferably made in the shape of an inverted short cylinder closed at its upper end, as at 11. The bottom edge of the base is preferably provided with small apertures 12 for the inlet of air. Upon the base is secured centrally thereof a flanged collar 13 having internal threads, as at 14, for receiving a short standard pipe 15, the upper end of which is similarly threaded to an elbow 16. This elbow carries a nipple 17 secured therein by threads and the opposite end of the nipple is threaded into a fuel mixer 18. The latter has a downwardly directed shank 19 into which is threaded a gas cock 2O adapted to receive a gas hose 21 in the usual manner. The fuel mixer has an aperture `22, preferably opposite the nipple 17, and

at its upper end a shank 28 into which is threaded a second short nipple 24.

The nipple 211 is connected by threads, as at 25, with a burner 26. This burner consists of a pipe-T 27. At the opposite ends of the pipel" 27 are carried short pipes 28, the outer ends of which are inserted in the elbows 29 and 30 and a transverse pipe 31 connects the ends of the elbows 29 and 30. The elbows 29 and 30 as well as the pipes 28 and 81 are provided with a series of small perforations B2, four to sin rows of these being preferably provided in the length direction of the pipes, as indicated in Figure 1. The T 27 has also several small perforations 33.

.above the burner is furnished a reflector 234i which, in Figures 1 and 2, has the shape of a cone., The base of the cone is about twenty inches in diameter and the inner side thereof is furnished with a sheet 0f asbestos which is secured'to theV cone by a. band 36 having hooks 87 at its ends embracing the edges of the asbestos sheet. The band is held securely near the apex of the cone'by a screw connection 38. The reflector cone 34 is carried with its axis at an inclination and it is secured by means of a screw 39 which is threaded into the rear side of the pipe-T 27 and penetrates the asbestos sheet at this point. In addition other screws Al() may be provided for securing the reflector to the elbows 29 and 30.

The gas cock 2O is provided with a plug 41 having a small central opening. as at 42, thus forming the nozzle for admitting the gas from the hos-e 21 into the mixing chamber 18. The jet of gas being directlv beneath the opening of the nipple 24 leading into the burner 26, said jet of gas meets with air currents entering through the opening` 22 and from the base 11 through the nipple 17. In this manner 'the desired fuel mixture is obtained and the richness thereof may be modified by the proper setting of the handle da of the gas cock. After the burner has been ignited at the small perforations 32 and 33 and the heater properly started, only blue flames emit from these perforations giving a complete combustion.

A heater for family use suitable to heat a room twenty feet long by twenty feet wide is made of one-half inch standard pipe iittings and carries a burner about ten inches.l long and a reflector twenty inches in diameter. For larger rooms, a larger heater should be supplied, using pipes of larger diameter and a burner of increased length having a greater number of small perforations and the nozzle also having a larger perforation for the gas jet. The heater is built on the principle that the air openings in the burner should be about twice the .area of the channel through which the mixture passes to the burner and the area of the opening' for gas to the mixing' chamber about one-fiftieth the size of the same channel.

In Figure 3 is shown a gas heater provided with a burner carried on a fuel mixer 46 and having a 4reflector 47 of slightly different character to that described above. In this case, the fuel mixer 46 is attached to an air cock 48 which is threaded on the end of the gas pipe 49 connected with the main gas supply. In this manner the heater forms a fixture in the room without' a base. The reflector 47 is in this case made from a flat square or rectangular plate bent along a longitudinal line at its middle, thus forming' two wings. It is shown as carrying a guard 50 constructed of' metallic wire attached to the edge of the reflector, as at 51. The reflector is as before secured by screws 60 and is provided with an asbestos lining 62 and a handle 61.

In Figure 4 is shown a heater having the same burner 52 as described above to which the reflector .into almost upright position, as shown by dotted lines at '57, or into horizontal position, as shown by dotted lines at 58.

lIt is evident that the lreflector may be given any intermediary position, as indicated by full lines, as at 59. When in horizontal posi` tion indicated b-y the dotted lines 58, the burner 52 will. throw the heat on the under side of the reflector and the latter may be used as a hot plate upon which may be placed `a cooking utensil.

rIhe burneris practically selfeadiusting up to the capacity of the burner. It heats the upper part of' the burner red hot and the more heat produced the greater is the draft of air through the mixing chamber. Consequently, the consumption of gas is correspondingly increased when air draft is set up for the mixing of vfuel anda greater heat produced. A blueflame and a perfect combustion is obtained andall the heat the gas can give is furnished without soot or smoke.

Having thus described the invention, I claim:

A gas heater comprising a 'fuelmixing member having lateral air intake ports, an outlet nipple leading from the top of the fuel-mixing member, a gas intake in the bottom of the fuel-mixing member alined ver` tically with the outlet nipple, a. T-coupling secured upon the upper end of the outlet nipple, erforated pipes secured in the ends of the 'I'P upon the outer ends of said pipes and extending upward-ly, and a perforated pipe connecting the upper ends of said elbows.

In testimony whereof I a-Hix my signature.
