GAS STOVE.

Application filed November 28, 1923. Serial No. 677,359.

To all whom it may concern:

Be it known that I, OTHMAR MAJOEN, a citizen of Austria, residing at New York, in the county of Bronx and State of New York, have invented certain new and useful Improvements in Gas Stoves, of which the following is a specification.

This invention relates to improvements in gas heaters and more particularly to such types as are used in the manner of stoves for warming rooms or like compartments in dwellings, stores or other building in which it is desired to raise the temperature. a

One of the objects of the invention is to provide a heater in which the gas is more tical manner.

Another purpose is to produce a'heater that is readily portable and which presents an attractive and pleasing appearance.

A further aim is in the provision of a device in which the gas is economically consumed, without waste, no odor or gaseous emanations being perceptible.

These and other important aims, objects and purposes are accomplished by the novel construction, combination and arrangement of parts hereafter described and illustrated in the accompanying drawing, forming a material part of this disclosure, and in which:---- I Figure 1 is a plan view of an embodiment of the invention as assembled for use.

Figure 2 is a vertical section.

The heater, as shown in the. drawing, is of very simple construction, consisting of a cylindrical body or casing designated by the numeral 10, the same having a rolled or beaded top edge 11 and rests on a base 12 over a raised annular projection 13 to which it is firmly secured by screws 14.

The base 12 is expanded outwardly into a dome shaped lower portion having an ornamental re-enforcing beading 15 at its lower edge and is supported by feet 16 se cured by'rivets or screws as shown, the feet raising the base to such height as maybe considered desirable.

. Formed through the casing, in its lower portion are a plurality of openings 17 to admit air in addition to that which enters below the'base.

Mounted on the rolled beading 11 is a curved cover 18 having a beaded lower edge 19 and containing a plurality of perforations 20. The main upper portion of the plate 18 is flat and level, as at 21, and has a central concave depressed surface 22, through which is made an opening for the cylindrical portion of the burner head 23. Said head has a cover plate provided with a plurality of raised nipples or protuberances 24 having perforations to allow the passage of gas, being in effect burners, each having an independent flamewhen the gas is ignited.

Gas is supplied to the burner head by a pipe 25 entering the lower convex portion of the head and then being bent at a right angle to extend outwardly through the wall of the casing 10, a flange 26 being provided at the joint.

The gas inlet pipe is curved downwardly beyond the flange and provided with a control means as the cook 27 having a connection 28 to receive a flexible tube (not shown) leading from the gas supply.

Inside the casing '10, adjacent the flange 26 is a collar '29 having an opening 30 which may be turned to register with a simi ar opening-in the pipe 25 and acting as a control valve for the inlet of atmospheric air from the interior of the casing to the pipe where the air comingles with the gas, forming a gaseous mixture to be ignited at the burners 24.

burner head 23 is a hood 31 made of foraminous material, as a woven metallic gauze or net capable of withstanding a high degree of heat, such as is commonly known as white hot, that is approximately incan descence, from the numerous burners below it.

This hood 31 is concavo-convex in shape, as shown,.and re-enforced by a wired bead 32 at its edge which is disposed substantially liln a.i plane level with the top of the burner From the foregoing it will be understood that the heat is disseminated from the hood rather than direct from the burners and it will be clear that no gas can escape, the gaseous mixture supplied by the burner head being positively consumed without waste and that a high degree of efliciency is thus attained.

In order to protect the hood from'acci-' dental injury and to prevent clothing or .Attached to the upper beaded edge of the other objects from being brought into dan- I gerous proximity, a series of guards 33 are bent into loop shaped formations, the curved portions being raised to a considerable height above the hood and their lower, straight ends secured in the cover plate 18 at suitably spaced intervals.

The crossed, upstanding portions of the guards are secured at their juncture with those disposed in transverse relation, constituting an effective barrier in preventing too intimate contact with the heat engendering and transmitting hood.

From the foregoing it will be seen that an efl'ective embodiment of gas heater has been disclosed in its preferred form, but it will be understood that minor modifications may be made, within the scope of the invention as hereafter claimed and which do not constitute a departure therefrom.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is

1; A gas heater comprising a casing open at the bottom and sides to the atmosphere, a cover extended over said casing, a burner head projecting through said cover, said head having a plurality of raised nipples, a feed pipe for said head, said pipe having a valve, controllable means for the inlet of air to said feed pipe, a foraminous hood disposed over said head, and a guard device fixed to said cover over said hood.

2. A gas heater comprising a casing open at the bottom and sides to the atmosphere, a curved cover having a beaded and perforated lower edge extended over said casing, a burner. head projecting through said cover, a plurality of raised nipples on said head, a feed pipe for said head curved downward ly, a perforated collar within said casing on said feed pipe inlcommunication therewith for controlling the inlet of atmospheric air to said feed pipe, a woven metallic gauze hood disposed over said head, and a plurality of loop guards extending above the hood and having their lower straight ends secured in said cover.

In witness whereof I have aflixed my signature.
