GUSTAVE F. SCHMIDT, OF CHICAGO, ILLINOIS.

GAS HEATER.

Application filed May 11, 1922. Serial No. 559,991.

T 0 all whom it may concern.

Be it known that I, GUsrAvn F. SCHMIDT, a citizen of the United States, and a resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Gas Heaters, of which the following is a description, reference being had to the accompanying drawings, which form a part of my application.

My invention relates to gas heaters of the type employing a plurality of heat radiating elements or radiants in conjunction with a burner having a plurality of tips corresponding in number with the radiants.

Generally stated, my invention consists in providing a base portion or burner housing unit on which is mounted the main heater unit or radiant-holding portion, which latter consists of a single unit preferably composed of earthen material, such as majolica, or other suitable clay, which may be provided. with a glaze or enamel finish of any desired coloration or effect in keeping with the wishes of the user and in harmony with the finish or furnishings of the apartment in which the heater is to be placed.

The invention also contemplates the construction of the radiant-carrying unit in such manner that the gases of combustion from the heater may readily be conveyed to a suitablerconduit or flue and thus prevent the possibility of obnoxious odors or vitiating gases escaping into the room.

The invention further contemplates a heater wherein the different radiating elements or radiants will all be removably secured to the main body unit in a manner which will permit their easy removal singly or en masse, thus permitting the main body unit with all of the radiants to be removed from the base or burner housing unit without interfering with or effecting the relation between the radiants and the main heater unit or interfering with the burner per se and the base or housing unit.

The objects and various advantages of my invention will all be more readily comprehended from the following detailed description of the drawings, wherein Figure 1 is a front elevation of my improved heater, with portions broken away and shown in section. I V

Figure 4' is a detail sectional view taken on the line lt of Figure 1 looking in the direction of the arrows.

Figure 5 is a detail sectional view taken on the line 55 of Figure 4: looking in the direction of the arrows.

My invention is especially adapted to a gas heater wherein the main portion is composed of earthen material, although the invention may, in many respects, be employed in radiant gas heaters made entirely of metal. The invention in its specific embodiment as disclosed in the drawings, comprises a rectangular base portion or unit 10 which is preferably made of metal and of skeleton or shell formation, namely with a front and two end walls which terminate at the top in a horizontally disposed flange portion 11 on which the main heater unit 12 is adapted to rest. As the heater is usually placed adjacent to a wall or in a fireplace, the rear of the base portion 10 may be open, which enables the base unit to be more easily adjusted or placed in position relative to the burner, which latter is shown at 13 in Figure 1, and also permit passage for the feed' or gas-pipe leading to the burner.

In the particular exemplification, the burner 13 is shown secured to and supported by the flange 11 of the base portion 10 by means of small screws or bolts, as at 14 in Figure 1, which are adapted to pass through tapped apertures in the flange portion 11 and through a suitable lugas at 15 cast integral with both ends of the burner 13. The burner is provided with a series of tips as at 15* which are adapted to extend into a plane substantially flush with the top of the base unit 10 and be disposed through suitable openings provided in a metallic plate or radiant-rest shown at 16 in Figure 2. The radiant-rest 16 in turn is preferably provided at the forward edge thereof with an upwardly and downwardly disposed flange 17 whereby the radiant-rest or plate may be properly positioned and the lower ends of the radiants which are shown at 18, held against possible displacement or forward movement, so that the position of the lower'ends of the radiants will be maintained and said radiants held in register with the respective burner-dips,-

The burner 13, at one end, is provided with a suitable valve as at 19 in Figure 3 for controlling the flow of gas into the burner; the valve being also constructed to 'admit a regulable amount of air. into the mixing end or chamber of the burner as is usual. The valve is shown provided'with a stem 20, preferably provided with a key or hand-wheel, disposed in proximity to one of the panels or sections of the base 10 and which panels, for the sake of artistic appearance, have been shown of circular formation as at 21, while the panel adjacent the handvalve is'preferably made removable to permit' access to the valve. The removable panel 21 is shown in detail in Figures 1 and 5 and has its rear side preferably provided with angular lugs as at 22 which are adapted to engage with'or hook over the flange portion 23 which extends into or encircles the lower part of the opening in the front wall of the base portion in slight lapping relationwith the removable panel 21. This construction permits the panel 21 to be readily removed by simply lifting it slightly upward sufficient for the angular lugs 22 to clear the flange portion 23, as is clearly evident from the construction shown in Figures 4c and 5. a

The main body or radiant-holding unit 12 of the heater is preferably shown in the I drawing composed of earthen ware formed to constitute the side portions,back-wall and top as a single unit; and this main body is 1 preferably made hollow as shown in Figures 2 and 8; thus providing a double back wallback as at 24 in Figure 2 which is preferably united by reenforcing ribs 25; while the continuous side and top portion likewise is chambered or hollow and thereby provides a chamber 26 in the upper part of the unit which, at a central point, is preferably provided with an outlet at 27 adapted to re ceive a conveying conduit or flue whereby the gases of combustion may be conveyed from the heater to the exterior of the room or building. The top portion 28 of the radiant-holding unit of the heater, and the side portions arepreferably formed to project slightly beyond the forward portion of the back-wall 2e, as shown in Figure 3, a distance sufiicient to provide a recess and permit the radiants 18 to be assembled in juxtaposition to the back-wall and at the same time come within the plane of the forward edge of the side portions and top of the radiant-holding unit 12, as shown in Figure 8. Th overhanging top portion 28 is preferably provided with a series of openings or a continuous slot, as at29 in Figure 3 which communicates with the chamber 26 and thereby permits the gases to pass upward and into the chamber 26, from which they will be conveyed by the opening 27.

The side portions of the radiant-holding unit 12, adjacent the top, are each provided with an opening as at in Figure 1 to receive the ends of a suitable rod or wire 31 on which the various radiants 18 are threaded or strung. The rod or wire 31, of suitable metal, is adapted to pass through correlated openings in the sides of the hollow radiants as shown in Figures 1 and 3, and the ends of the rod or wire provided with an enlargement or bend as at 32 in Figure 1 which is intended to extend into the openings 30 so as to lock the ends of the wire in place. and thereby maintain the radiants in proper position relative to the radiantrest or plate 16. The openings 30 may be in the nature of bayonet-slots, with the enlarged ends of the openings uppermost so that after the enlarged or bent ends of the rod or wire have been passed through the upper end of the slots andthe radiants allowed to seat onthe rest or plate 16, the enlarged-or bent ends of the rod or wire will interlock with the restricted or lower ends of the slots or openings and prevent accidental removal. As is clearly evident from this construction, all of the radiants may be readily lifted out of place when-it is desired to replace any. or all of them, or to remove the main body portion or unit 12 of the heater, for the purpose of substituting a new or different unit.

With the radiant-holding unit 12 made of clay, it may be provided at suitable points with a slight slit or cut as set forth in my prior application, Serial No. 524,941, to compensate for expansion and contraction and thus prevent possibility of cracking or breaking of the enameled surface..

The construction of heater as shown and described, consisting of a base portion or unit 10 and a main portion or radiant-holding unit 12, permits ready access to all ofthe parts for cleaning or repairas'well as for shipment and storage; andit is also ap-' parent that the base portion or burner housing unit 10 maybe employed with any type of suitable burner, as for example the type illustrated in my pending application, Serial No. 524,941, wherein the burner is sup-- ported on the floor, thus permitting the base unit 10 to be readily removed without disturbing the burner per se. It is also evident that the'base unit may be removed and a different style base unit substituted as is also the case with the main portion or radiant-holding unit; the construction permitting an interchange of the respective units to meet the desires or wishes of the user without necessitating removing or changing the entire heater.

In practice, after the burner has been secured in place at the point desired, the base unit 10 is then placed over or about the burner so as to properly'enclose the same, after which the main body portion or radiant holding unit 12 is put into place on top of the base portion so as to have the lower parts of the radiants in proper register with the burner tips. With the main portion or radiant-holding unit composed of earthen ware or clay, it will be of sufficient weight and proportions to maintain its position on the base portion without requiring special means for securing it in place. As the flange ll of the front wall of the base portion merely extends a short distance rearward, it is evident that a sufficient air space will be provided between the front part of the rear wall 24 and the rear edge of the radiant rest or plate 16 to permit the upward passage of air whereby to enhance combustion.

I have shown what I believe to be the simplest and best embodiment of my invention which has been described in terms employed merely as terms of description and not as terms of limitation, as structural modifications are possible and may be made without. however, departing from the spirit of my invention.
