Application filed February 26, 1919 Serial No. 279,334.

To all whom it may concern:

Be it known that We, GEORGE H; IRVING,

, of Hayward, Alameda county, State of burner.

California, and BRADLEY F. D RPHY, of the city and county of San Francisco, State of California, both citizens of the United States, have invented new anduseful Improvements in Burners, of which the following is a specification.

Th1s invention relates generally t hy ra;

carbon burners and particularly to that class known as generator burners.

One of the objects of the present invention is to provide a combination gas generator and burner which is simple and compact in construction, cheap to manufacture and suitable for various installations, as stoves, ranges, etc.

Another object of the invention is to provide a generator and burner which 'is particularly adapted for handling kerosene and like low gravity oils and which is provided with a novel arrangement of coils through which the oil is passed and generated to a gas before delivery to the burner. Further objects will hereinafterappear.

The invention consists of the parts and the construction, combination and arrangement of parts as hereinafter more fully described and claimed, having reference to the accompanying drawings, in which- Figure 1 is a perspective view of the Fig. 2 is a central vertical section through the same.

Referring to the drawings in detail, A indicates a pipe which is connected with a needle valve 2 and a feed pipe 3. The pipe A terminates in a horizontally disposed double coil shown at i and 5, which finally terminates in a vertically disposed U-shaped extension 6. One end of the U-shaped extension is formed integral with the coil, as shown at 7, while the opposite end of the section is welded to the outer portion of the coil 5, as shown at 8, a hole being drilled in the upper portion of the coil 5 to permit communication between said coil and the U-shaped extension. The pipe A coiled and formed as here shown, serves both as a gas generator and as a burner; that is, oil admitted through the valve 2 and entering pipe A, passes through the coils 4 and 5 which are heated, as will hereinafter be described The oil is thus converted to gas,

which passes upwardly through the two legs 9 of the U-shaped extension and is then permitted to escape through perforation 10 formed on the upper portion oftheextension and on the underside thereof.

,flTheperforation 10, for what may be termed the discharge nozzle of the'burner,

is centrally disposed with relation. to the coils. 4L and 5 and the gas discharging will therefore pass centrally between the coils and when ignited, produces a flame practically blue in color and intense in temperature. A burner ofthe character here shown is exceedingly cheap to manufacture as nothing is employed in its construction outside of the pipe A, which is merely bent to form the coils 4 and 5 and the U-shaped extension 6. It is furthermore compact in construction, thereby permitting it to be readily installed in stoves, ranges, etc. When placed in a stove or range it is obvious it may be placed directly on top of a bed of brick or fire clay and slightly spaced therefrom to permit the downwardly projected flame to spread out over the brick radially in all directions beneath the coils 4 and 5. The coils are thus maintained at a comparatively high temperature, which insures a perfect generation of gas and the life of the same is in this instance comparatively great as they are not exposed to the direct action of the flame.

While brick or fire clay forms a desirable bed or support for the burner, it is obvious that a plate such as shown at 11, may be employed, if desired, to spread and distribute the flame. We, however, prefer a heat retaining medium, such as brick or its equivalent as this gradually attains a red hot temperature which assists in maintaining the heat after the burner has been shut down and also assist in distributing the heat more evenly throughout the fire-box.

While ordinary black iron pipe may be employed in the construction of the generator and burner, we wish it understood that the materials and finish of the same may be such as the experience and judgment of the manufacturer may dictate; similarly, that any form of oil regulating means, such as the valve 2, may be employed; and that the position or installation of the burner may be varied to suit its various applications.

Having thus described our invention,

What we claim and desire to secure by Let'- ters Patent is 1. A burner comprising a horizontal coil of tubing connected at one end with a supply source and bent upwardly at the other end to. form a vertical U-shaped arch with the apex above the center of the coil and the outer leg ot the U connected with and opening into the outer convolution of the coil, the apex of the arch having a nozzle through which gas is discharged downward into the center of the coil from both branches of the arch.

2. In a burner of the character described,

\ a horizontal table or bed, a horizontal coil of pipe located above the table, and a source of supply'and controlling valve with which Copies of this patent may be obtained for one end of the coil is connected, the opposite end of the coil being turned to form a vertical U-shaped arch, with the apex having a nozzle directed downward to the center of the coil, and the outer leg of the arch connected with the outer convolution of the coil, whereby gas is delivered through both legs of the arch to the nozzle and dispersed by the table around the coils.

In testimony whereof we have hereunto set our hands in the presence of two subscribing witnesses.
