GAS-BURNER.

Specification of Letters Patent.

Patented Apr. a, 191W.

Application filed October 12, 1916. Serial No. 125,153.

To all whom it may concern:

Be it known that I, Tnnooonn A. I'IOLM- nnne, a citizen of the United States, residing at Cleveland, in the county ofCuyahoga and State of Ohio, have invented certain new and useful Improvements in Gas-Burners, of which the following is a specification.

My invention relates to improvements in gas burners, and more particularly to that class or type known as inclosed flame gas burners, the present embodiment of this i11- vention being particularly designed and adapted for use in large ovens for providing a proper circulation of heated air for baking and drying various commercial articles, as in enameling, japanning, baking, drying and the like.

The primary object of the invention is to provide a generally improved burner of this class which will be exceedinglysimple, cheap, and eflicient in use, as Well as one in which the parts are so constructed and arranged relative to each other as to result in a more perfect combustion within the generator, im proved means being provided for supplying air under pressure within the generator, and thereby forcing highly heated air from the latter into the oven under pressure giving an even and rapid circulation for driving off dampness and fumes from the oven and articles being baked or. dried.

A further object is the provision of an improved generator or combustion chamber in which a more complete combustion and a more rapid circulation of heated air is pro vided, as Well as one in which the various burner and air distributing pipes and nozzles will be rendered more durable and efficient in service.

With the above mentioned and other ends in view, the invention consists in the novel construction, arrangement, and combination of parts, hereinafter described, illustrated in one of its embodiments in the accompanying drawings, and particularly pointed out in the appended claims.

Referring to the drawings, forming a part of this specification, Figure 1, is an end view of the front or air and gas receiving end of a burner constructed in accordance with this invention.

Fig. 2, a cross sectional view of the same.

Fig. 3, a top plan view of the same, a portion of the generator or flame inclosing casing being broken away for the purpose of Clearer illustration of parts.

Fig. 4, a side elevation of the same, the gas burner pipes being removed.

Similar numerals of reference designate like parts throughout all the figures of the drawings.

The improved gas burner comprises a generator or flame inclosing casing 1, which is preferably made up of a series of sections or units terminating at their ends in flanges 1 the latter adapted to be connected in any suitable and convenient manner to form a generator of suitable length to conform to the dimensions of the oven in which it is to be used.

The sections or units of the generator casing are preferably provided 'at their ends with legs or supports 1 to rest upon the floor of the oven, suitable air circulating passages or recesses 1, being provided between the legs or supports and on each side leading to the base portion of the generator casing.

The end sections or units are preferably provided with cylindrical heads 1, the head 1, at the front, being adapted tobe intersected by suitable air and gas conduit pipes 2, and 3, respectively, leading to the air distribution and gas burner pipes within the casing 1, hereinafter described. The air and gas conduit pipes 2, and 8, may be provided with suitable valves for-regulating the flow of air and gas, but such valves forming no part of this invention need not be shown or described.

As a means of heating the air as well as providing for proper combustion within the generator casing or combustion chamber provided by the latter suitable longitudinally extending gas burners 4, are provided, said burners hin the present instance, being in the form of longitudinally extending burner pipes suitably spaced apart and communicating with the gas conduit pipe 3, at the front.

As a means of properly distributing the hot air and products of combustion from the generator or fiame inclosing casing 1, the latter is provided with a series of heat distributing laterals or pipes 5, suitably spaced and located, said pipes terminating at their ends in upwardly extending portions 5*, provided with suitable air distributing caps 5 the latter being spaced above the outlet portions 5 to provide outlet portions 5,

intermediate the caps 5 and the upwardly extending portions 5*.

As a means of further promoting combustion and accelerating the passage of hot air and the products of combustion from the burners 4, and through the heat distributing laterals 5, an air conduit pipe 6, is mounted within the generator casing 1, above the is also provided along its top and substantially midway between the air distributing pipes G, with vertically extending air distributing pipes 6*, adapted to discharge air within the top or dome portion of the' gen 'erator or flame inclosing casing 1, as shown most clearly in Fig. 2 of the drawings.

' The air conduit pipe 6, may be supported at suitable intervals throughout its length with cross bars 1?, within the casing 1, (see Fig. 2,) and it will ,be observed that by reason of'the location of the pipe 6, and air distributing laterals 6, above the burner pipes 4, the gas flames issuing from the latter will act to heat the pipe 6,-and laterals 6, and

the air issuing from the same, the air issuing from the air distributing laterals (i and into and through the heat distributing laterals 5, constantly carrying oft and distributing the heated air and the products of com- .bustion arising from and over the burners 4, and this circulation of air also adds longer life to the burner pipes 4C, for obvious reasons.

From the foregoing description, taken in connection with the accompanying drawings, the operation and advantages of my invention will be readily understood.

Having thus described one of the embodiments of my invention, what I claim and desire to secure by Letters Patent, is,

1. In a gas burner, a generator casing made up or a plurality of sections open at theirbottoms and provided with heat distributing lateral pipes terminating in upwardly extending portions covered with spaced air distributing caps.

2. In a gas burner, a generator casing open at its bottom and provided at its sides with heat distributing laterals, a pipe provided with air distributing laterals in alinement with said heat distributing laterals, and gas burners in said casing above said open bottom of said casing and below said pipe and air distributing laterals.

8. In a gas burner, a generator easing provided with heat distributing laterals, an air conduit pipe therein provided with air distributing laterals in alinement with and leading to said heat distributing laterals, and gas burner pipes in said generator casing Copies of this patent may be obtained for below said air conduit pipe and heat and air distributing laterals.

4. In a gas burner, a flame inclosing generator casing provided with lateral heat distributing pipes, a central air conduit therein provided with laterals in alinement with and adapted to discharge air through said lateral heat distributing pipes, and gas burners in said casing below said air conduit and laterals whereby the latter are heated and the products of combustion are carried through said heat distributing pipe with the air discharged therein by said air discharging laterals.

5. In a gas burner, an elongated flame inclosing generator casing open at its bottom and provided with supporting legs, a series of lateral air distributing pipes extending from thesides of said casing, and an air conduit pipe in said casing provided with air distributing laterals in alinement with said lateral air distributing pipes, and upwardly extending air distributing pipes intermediate the latter and below the dome portion of said casing.

6. In a gas burner, an elongated generatorcasing made up of connected sections provided vith air inlet passages in their bottom portions and heat distributing lateral pipes at their sides, gas burner pipes above said air inlet passages, and an air conduit pipe above said burner pipes and provided with air distributing laterals adapted to discharge air through said heat distributing lateral .pipes whereby the heat and products of combustion arising from said burner pipes are carried through said lateral pipes with the air discharged therein by said air discharging laterals.

7. In a gas burner, an elongated flame inclosing generator casing provided with an open bottom and air inlet passages leading thereto, heat distributing lateral pipes at the sides of said casing, an air conduit in said casing provided with air distributing laterals in alinement with and adapted to discharge air through said heat distributing lateral pipes, and gas burner pipes in said casing above said air inlet passages and below Said air conduit and air distributing laterals whereby the latter are heated and the products of combustion are accelerated in their passage through said heat distributing lateral pipes.

In testimony whereof I have aflixed my signature in the presence of two witnesses.
