SAMUEL TULLY WILLSON, OF BROOKLYN, NEW YORK.

BURNER-HEAD.

Specification of Letters Patent. Patented Dec. 31, 1918.

Application filed February 6, 1916. Serial No. 146,991.

To all whom it may concern Be it known that I, SAMUEL TULLY W nn- SON, a citizen of the United States, resldmg at Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Burner- Heads'; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to burner heads for gaseous fuel, and it has for an object, to

provide a burner head which affords great concentration of heat.

Another object of this invention is to provide a burner head in which rapid flame propagation of gaseous fuel occurs.

A further object of this invention is the provision of a burner head for gaseous fuel produces a in which combustion of'the fuel short flame of intense heat.

A further object of this invention is a provision of a burner head for gaseous fuel ,head, and

in which the flame plate is used, said flame plate being so formed as to permit partial or complete combustion of a fuel within apertures formed therein.

A further object of this invention is a' provision of a flame plate for burner heads having apertures formed therein, in which combustion of a gaseous fuel occurs.

A further object of this invention is the provision of a plate of refractory material having apertures formed therein, in which combustion of a gaseous fuel occurs, said apertures being so arranged as to preclude the liability to back fire. I

Further objects will be apparent from the following specification, appended claims and drawings, in which- Figure 1 is a plan view of the burner Fig. 2 is a vertical cross section therethrough, as on the line 22 of Fig. 1.

This burner head provides for the generation of intense heat in limited space, and this is accomplished by rapid flame propagation in a flame plate which is of refractory material. This flame plate is provided with apertures in which partial combustion of a gaseous fuel occurs and these apertures are so formed as to cause the gaseous fuel to be admitted into them at their base at such velocities, dependenton the nature of the gaseous fuel, to cause rapid combustion of the fuel and also to prevent back fire into the distributing chamber. This refractory head, upon becoming heated to incandescence by the combustion of the gaseous fuel, within its confines throws ofi' an'intense radiant heat and, as will be disclosed in the following specification, this' flame plate may be placed in close proximity to a surface being heated.

Referring to the drawing (more especially Fig. 2) in which the several features of this invention are clearly shown, 10 indicates a flame plate having apertures 11 formed therein which have a diameter equal to approximately one-half of their length. This flame plate is supported by the side wall 12 rising above the partition 13. Extending below the partition 13 is the downwardly tapering wall 14 to form a distributing chamber 15. The foregoing comprises what may be termed the burner head, and this may be supported by the nipple 16,

clbow 17 and supply pipe 18 through which that radiant heat is thrown off when this plate has been heated to incandes3ence. but the side wall 12, partition 13 and shell 14 are of metal which transfers the heat by COIlCluctiOn toward the cooler portions to maintain the temperature of these parts below ignition point of the gas. These apertures are of such predetermined cross sectional area as to properly permit combustion of a gaseous fuel therein.

The partition 13 has passages 19 formed therein which communicate with the lower portions of the apertures 11 and these passages are preferably concentric with the apertures 11. The diameters of the passages 19 are approximately one-third of the diameters of the apertures 11, but proportionment may be varied in the burner head as used for gases of different characteristics.

These passages form jets which admit the 18 properly mixed with the desired volumes cence, at which time an intense radiant heat is thrown ofl. The apertures 11 are proportioned to allow gaseous fuel being partially consumed therein, having the apex of the flame occur slightly above the upper surface of the flame plate, and as the gaseous fuel is fed 'through the passages 19, a chilling action is had which serves to prevent the partition 13 from becon ing'heated to such a degree as to ignite the gas and likewisethe lower face of the flame plate is also maintained at a degree of heat below the ignition point.

It is apparent to those familiar withthis type of apparatus, that the number of apertures in the flame plate may be increased or decreased as desired but in each instance, the

resultant action will be similar.

Having thus described this invention, I claim:

1Q A gas burner comprising a head having a distributing chamber formed therein, apartition in said head, a refractory flame plate carried by said partition, said refractory flame plate having apertures therein in which combustion of a gaseous fuel occurs to heat said refractory flame plate to incandescence and thereby creating radiant heat, said partition having passages formed therein communicating with said apertures, said passages being proportioned to admit gaseous fuel into said apertures at a velocity to prevent back fire into the mixing chamber and said passages serving to maintain the temperature of said partition below the ignition point.' a

2. In a burner head ofcthe class described, a fitting, a partition across said fitting to form a distributing chamber, said partition having passages therein which communicate with said distributing chamber, a side wall rising above said partition, and a flame plate of refractory material having apertures formed therein which register with the passages in the partition, but having said apertures of a cross sectional area increased relatively to the cross-sectionalarea of saidpassing from said distributing chamber, a

flame plate of refractory material carried by said partition within said side wall, said flame plate having apertures formed therein which register with said passages havingsaid apertures of increased cross-sectional area than the area of said passages, and having enlarged webs of the refractory matgrial comprising said flame plate formed between said apertures so that in the combustion of a gaseous fuel within said apertures, these webs and the adjacent portions of said flame plate are heated to a degree of incandescence to thereby form radiant heat.

4. In a burner head of the class described, a fitting, a partition within said fitting forming a. distributing chamber, a side wall surrounding said partition and rising above the level thereof, a flame plate of refractory material carried by said partition within said side wall, said partition having reduced passages ,formed therein through which volumes of gaseous fuel are discharged from the distributing chamber, said fitting and partition being of a heat conducting material to thereby conduct the imparted heat and dissipate the same, said refractory flame plate having apertures formed therein which register with the passages in said partition, and which are of relatively larger cross-sectional area than the area of said passages, and said partition and flame plate having the passages and apertures so formed therein as to have enlarged webs of the refractory material between said apertures.

In testimony whereof I aflix my signature.

SAMUEL TULLY WILLSON.
