GAS BURNER.

Application filedk October 14, 1926. Serial No. 141,445.

This invention relates generally to burners for gaseous fuels, and particularly to a special type of burner by means of which complete combustion can be secured.

The first object of this invention is to construct a burner which will completely consume all of the gaseous fuel, or rather utilize all of the heat units contained therein, making same available for whatever purpose desired.

The second object is to construct a burner whose flame cannot readily be extinguished by draughts of air, and which will not be subject to the ordinary back firing diiculties common to most gas' burners.

The third object is to construct a burner in which the gas being consumed is pre-heated to an unusually high degree before entering the flame, thereby maintaining a requisite condition for combustion.

These, and other objects, will become more apparent from the specification following as illustrated in the accompanying drawing, in which:

Figure 1 is a perspective view of one end of the burner showing a portion broken away to disclose the construction thereof. Figure 2 is a transverse section through the burner. Figure 3 is a vertical section taken along the line 3 3 in Figure 2. Figure 4 is a bottom view of the burner. Figure 5 is a plan of the burner. l

Similar numbers of reference refer to the same parts throughout the several views.

Referring in detail to the drawing, the burner itself consists of a longitudinal member having a pair of upwardly converging inner walls 10 and a pair of outer walls 11 spaced from the inner walls 10 and almost touching the same at their upper edges but spaced therefrom by means of the bosses 12, and secured thereto by means of the screws 13 which are threaded into the bosses 12. The walls 10 are slightly lower than the walls 11. Each wall 10 is provided with an outturned flange 14 which extends to the lower edge of the adjacent member 11. Bolts 15 hold the lower edge of each member 11 to its side of the burner.

Inner end walls 16 join the members 10 and outerl endL walls 17 join the members 11. A gas inlet pipe 18 enters one end wall 17. Covers 19 are provided over the end walls 16 and 17.

The operation of the burner is as follows: Gas entering the burner through the pipe 18 passes between the highly heated walls 10 and 11 and quickly rises in temperature almost to the point of combustion. When it escapes through the upper edges of the members 10 and 11 it does not rob heat froln the flame tip, as is ordinarily the case, but is immediately converted into a desirable flame.

The flame from the opposite side of the burner, which is in reality sheets of flame, intersects, as shown in Figure 2, and unites in producing an intensely hot flame tip to which air is fed from between the walls 10, as well as the exterior of the flame.

In ordinary burner construction the incoming gases are at a much lower temperature than that of the flame, tending, thereby, to cool same to a point where combustion becomes very imperfect and the amount of heat given olf is thereby greatly lessened.

We are aware that many forms of gas burners have been constructed in the past; we therefore do not claim such devicesbroadly, but we do intend to cover all such forms and modifications thereof as fall fairly within the .appended claim.

We claim:

A gas burner having al pair oflaterally spaced converging inner walls between which air can pass upwardly and having a pair of removable straight outer' walls spaced from said inner walls and converging toward the top thereof to form continuous, straight, longitudinal burner tips, a floor between the bottom end of said inner wall and its adjacent outer wall, end walls across said inner and outer walls, the space formed by said end walls communicating with the spaces between said inner and outer walls, and means for admitting gas into said spaces.
