v Ki ov/A r Patented Nov. 16, 1948 UNITED STATES PATENT OFFICE- CIRCULATING GAS HEATER ZEolian E. Moores, Dallas, Tex. Application October 30, 1945, Serial No. 625,467

2 Claims. 1 This invention relates to heating appliances and it has particular reference to gas heaters.

The principal'object of the invention is to provide a gas circulating heater consisting of a base element on which is mounteda reticulated housing in superimposed and independently demountable sections, each serving its own function with a view of utility and appearance.

Another object of the invention is to provide a burner supported in the base at or below its top,

. whose ends and sides are spaced inwardly of the ends and sides of the base to define an openarea intermediate the burner and base as well as within the confines of the burner in order to provide unrestricted circulation of air on each side of the radiants supported in and above the burner.

Another object of the invention is to provide an open frame supported on the burner for retaining replaceable radiants in perpendicularity to the burner along its sides and ends, said frame being further adapted to support a vaporizing pan of substantially the same length and width of the frame.

With the foregoing objects as paramount, the invention has further reference to certain features of accomplishment which will become apparent as the description proceeds, taken in connection with the accompanying drawing wherein:

Figure 1 is a perspective view of a heater embodying the principle of the present invention with the sections of the reticulated housing slightly displaced vertically to illustrate their separability.

Figure 2 is a plan view of the heater with the housing sections removed.

Figure 3 is a perspective view of the vaporizing pan, and 6 Figure 4 is a perspective view of the radiant frame, showing radiants thereon, certain of which are partly broken away.

Continuing with a more detailed description of the drawing, reference numeral I denotes a substantially rectangular base, supported on legs II. The base ID has formed thereon at one end, forwardly extending, parallel arms l2, the outer ends of which are formed with bosses l3 which support a service pipe M, on one end of which is a service connection l5. Another boss I6 is formed on the [base l0 through which passes the neck I! of a burner I8, to which further reference will be made presently. A short length of pipe l9 effects communication between the service pipe l4 and burner l8 and carries a conventional valve cook 20.

It will be observed, epecially in Figure 2, that the burner I8 is formed of a continuous pipe or casting whose sides and ends are parallel with but spaced inwardly from the sides and ends of the base Ill so that there will be provided an open area 2| intermediate the burner and base to permit air to circulate therethrough. Moreover, circulation is likewise afforded through the central area defined by the burner l8, hence making it possible to utilize to the maximum, the heat'given off by the radiants, which latter will be described presently. p

The burner I8 is supported in the base in by its being secured at one end by the neck I! passing through the boss IS on the base. The opposite end of the burner is supported by means of a protuberance 22 (Fig. 2) on the burner, which rests upon a bracket 23, extending inwardly from the end of the base.

Supported on the burner I8 is an open frame 24, shown in detail in Figure 4 which conforms to the general shape of the burner and which is so disposed in relation to the top of the 'burner that the orifices 25 in the latter will lie outside the ends and sides of the frame. Along the top and bottom of the frame are spaced, overhanging lips 26 which embrace the upper and lower edges of radiants 21, which latter consist of ceramic blocks or plates which are slid into place from the ends of the frame 24 and assume a position perpendicular to the plane of the burner l8. Each radiant has an outer face having studs a molded therein and has transverse perforations b therein throughout its area which is a further aid in equal distribution of heat radiated by the radiants 21, by permitting passage of preheated air through the radiants into the open central area of the burner for ascension through the reticulated housing to be described presently.

While not necessarily an essential element in the described combination, a pan 28, adapted to contain water for vaporization and humidification' purposes, is adapted to be supported on the top of frame 24'. This pan is shown in detail in Figure 3.

Among the outstanding characteristics of the invention is the safety feature in entirely enclosing the flames, to prevent ignition of clothing or other inflammable material. To accomplish this, a housing consisting of sections 29 and 30 are provided, the former having vertical walls provided with heat escape openings 3! while the uppermost section 30 is preferably formed as shown, with inclined walls provided with slots or other openings 32 and a reticulated top 33. The lower section 29 of the housing may be removed, if desired, and the uppermost section may he set directly on the base 10. Thus, the height of the heater may be reduced without interfering with its efiiciency or its ornamental appeal. It is also possible to remove the uppermost section, leaving the lower section 29 intact and cover the central area with the pan 28.

The features of convertibility described contribute much tohmaking the heater one .of general purpose with-"the paramount object to insure maximum heat and safety.

Manifestly, the construction as shown and described is capable of some modification and such modification as may be construed tci.;-f.allswithin the scope and meaning of the appended claims is also considered to be within the spirit and intent of the invention.

What is claimed is:

1. A heater comprising a substantiall'y're'ctam gular elevated base, a burner supported in said baseconsisting of a perforated, continuous pipe lyin'g parallel- 'withthe-sides and-"ends of said base but out 'of "contigu'ity' therewith to'definean air space intermediate the said base and *burner and within the confines" of "'thelatter, an open frame supper-tedon'said burner having spaced, overhanging 'lip-sg'r'adiants retained ina ve'rtical plane-on said-frame at its'sides' and-ends day-said *I-ips, a reticulated housing'in' separable horizontal "Sections superimposed --on' "said" base a' "shallow water pan supported on said frame and' -means *enteringthrough the 'erid-of 'said baseand'com- .the upper of said frame portions to define lips,
