Claims.
necessarily be limited to burners used in devices of this character. a
The primary object of the invention is the provision of a new and improved gas burner.
Another and further object of the invention is.
the provision of a burner having a quickly detachable burner cap of a new and improved construction.
Other specific objects, novel features of construction andimproved results of the burner will appear in more detail in the following description when read in the light of the accompanying drawing. In the drawing: Figure 1 is a top plan view of the burner. Fig. 2 is an enlarged sectional view through the burner.
Fig. 3 is an enlarged fragmentary detail view of' the corrugated or fiuted upper edge of the detachable burner cap.
Fig. 4 is an enlarged fragmentary detail view in section through a portion of the burner cap illustrating the construction of the interior or center burner ports and the application of enamel to the detachable burner cap.
The present burner constitutes a forward step in the art in providing a burner which is an improvement over the burner illustrated and described in the Stockstrom et al. Patent No. 1,714,- 409 of May 21, 1929.
To enable those skilled in the art to understand the present invention a detailed description follows with reference being had therein to the accompanying. drawing wherein like parts are designated by similar reference numerals throughout the description.
The burner comprises essentially a burner pot A having projecting therefrom a communicating manifold B and a removable burner cap C. Obviously, the manifold may extend in any desired direction from the burner pot without aifecting or difiering from the present improved invention, but for the purpose of illustration the manifold is shown in the drawing as extending horizontally from the burner chamber.
.A bracket 5 is provided as a part of the supporting means for the burner in a stove or other suitable or similar heater.
The burner housing, manifold and burner supporting bracket are composed of cast iron and the burner housing is of an annular shape having an.outer wall 6 and a shorter inner annular wall I in spaced and approximately parallel relation with the two walls joined together at their lower ends by a horizontally disposed portion 8 which forms the bottom of the housing. The housing 5' has an open outer end and the upper-edge of the outer housing wall 6 is tapereddownwardly and inwardly as clearly indicated at 9. The upper edge of the short inner annular wall 1 is inturnedand provided with a threaded opening "I. 10
The burner cap C is of light gauge steel pressed into an annular conical shape having at its small end a flange which forms a depending collar ll. As the metal making up this cap is of a light gauge there is not enough material for threading the short tubular or collar portion of the cap and accordingly this collar is exteriorly provided with two small bumps or bosses l2 which are adapted to engage the threaded opening ill of the burner housing in a manner similar to screw threads and thus removably secure the cap in place upon theopen outer end of the burner housing. y
The upper peripheral edge of the cap has pressed into it corrugations or flutes l3 which when the collar portion of the cap is screwed into the burner housing engage the tapered or beveled upper surface or end 9 of the outer burner housing wall 6. The formation of these corrugationslis clearly illustrated in Figure 3 of the drawins. 7
Intermediate its length the burner cap G is provided with a plurality of burner ports H which due to the conical shape of the burner cap will burn a flame which will have an impingement towards a common center. A shallow burner port is more subject to flash back with most gases than is a burner port having a greater depth. This is a fact well known to those skilled in the art. To overcome the likelihood of a "flash back at these burner ports which would have practically no depth were they merely pierced openings in the thin steel cap material, I have pierced the burner cap material and then placed and secured in the openings hollow rivets I5 thus giving to these .ports a depth much greater than they would have were the ports merely openings through the thin burner cap material. Thus the likelihood of a flash back from these burner ports is overcome in a new and original manner. It is to be understood that short tubular sections could be utilized rather than hollow rivets, although it is thought that thehollow rivet construction would be cheaper.
After the burner cap has been pressed into a proper" shape all of its surface, with the exception of its tubular collar portion II, is enameled as indicated at 16 to prevent possibility of corrosion, and incidentally to add to the appearance of the finished burner.
In operation it is to be understood that mixed air and gas for the burner enters the manifold B and is directed to the interior of the burner housing where it escapes through the burner ports l4 and is ignited and also escapes through the spaces formed by the engagement of the corrugated edge of the burner cap with the beveled upper end of the burner housing where it is also ignited and at which point it directs a series of flames outwardly throughout the annular peripheral edge of the burner chamber.
Secondary air is introduced through the hollow central portion of the burner chamber where it passes upwardly through the tubular collar portion H of the burner cap. The temperature of a gas flame is well over 2000 F. This being the case it is highly desirable and necessary to keep the steel burner cap at a temperature below its melting point. The incoming gas mixture introduced into the burner chamber produces a cooling effect on the burner cap as it passes through it to the gas burner orifices while a still greater cooling effect is had upon the burner cap by the incoming secondary air. The burner cap is further cooled by radiation into the cast iron burner chamber through its intimate contact with the burner chamber at its point of connection therewith.
It is to be noted that the present burner is a decided improvement over burners now known and in use in that the burner cap is of a cheap material and because the method of forming the burner cap at its upper edge to provide for burner orifices is a decided advantage. The burner cap is of a very light gauge of material and the provision of deep burner ports in a thin burner cap is accomplished in a new and novel manner. The manner of attaching the thin tubular collar of the burner cap to the burner housing without the use of screw threads on the cap is also novel. Completely enameling the burner cap to guard it against corrosion is a discovery which is novel and which saves expense in the production of the complete burner.
Having thus described my invention what I claim and desire to secure by Letters Patent is:
1. An improved burner comprising a housing having an open upper end and its central bottom portion elevated and provided with a threaded opening, the upper end of the housing being tapered inwardly and downwardly, a generally conical shaped thin sheet steel burner cap for closing the upper end of the housing, said cap having pressed in its large upper end throughout its periphery a series of corrugations, the lower small end of the cap being provided with an annular collar provided exteriorly with separated outwardly extending bumps adapted to threadedly engage the threaded opening in the housing bottom, said cap rotatable in the threaded housing opening to bring the downwardly extending corrugations of the cap into engagement with the tapered upper end of the housing, a series of burner ports pierced in said cap intermediate its ends, tubular members secured in said burner ports by pressure engagement with the opposite sides of the burner cap for deepening said ports, and said burner cap and tubular extensions being enameled to prevent corrosion.
2. An improved burner comprising a housing having an open upper end and having its bottom provided with a threaded opening, the upper end wall of the housing being tapered inwardly and downwardly. a generally conical shaped burner cap composed of thin sheet metal for closing the upper end of the housing, said cap having pressed into its large upper end throughout its periphery a series of corrugations, the lower small end of the cap being provided with an annular collar provided exteriorly with separated outwardly extending bumps adapted to threadably engage the threaded opening in the housing bottom, said cap rotatable in the threaded housing opening to bring the downwardly extending corrugations of the cap into engagement with the tapered upper end of the housing, a series of burner ports pierced in said. cap intermediate its ends, and tubular members secured in said burner ports by having their opposite ends in pressure engagement with the opposite sides of the burner cap for thickening the burner cap and deepening said ports.
3. An improvedburner comprising a housing provided with an opening, a thin metallic burner cap having pressed in its peripheral edge a series of corrugations, a second and threaded opening in said housing, said cap being provided with a collar provided externally with separated outwardly extending bumps adapted to threadedly engage the threaded opening in the housing, said cap rotatable in the threaded housing opening to bring the downwardly extending corrugations of the cap into engagement with the surrounding edge of the housing opening to provide a plurality of burner ports.
