OIL-BURNER.

Specification of Letters Patent.

Application filed June 23, 1911.

Serial No. 634,924.

To all whom 'it may concern:

Be it known that I, ELwooD S. LINE, a citizen of the United States, residing at Omaha, in the county of Douglas and State of Nebraska, have invented certain new and useful Improvements in Oil-Burners; 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 oil burners and has for an object to provide a burner of improved design and function to be inclosed within a stove of usual and ordinary construction and adapted to hold for igniting and consuming, oil fuel, especially crude petroleum. i c

A further object of the invention is to provide a burner having a feed pipe extending upwardly through the air inlet whereby the pipe is cooled until the ignition chamber is reached, then formed into a coil which is positioned to be subjected to the flame from the burner to vaporize the oil supply.

A further object of the invention is to provide an improved air inlet surrounding the feed pipe directed downwardly upon the ignition pan so that the air supplied through the inlet pipe is directed first downwardly directly upon the burning fuel contained in the pan.

With these and other objects in view the invention comprises certain novel constructions, combinations and arrangements of parts as will be hereinafter fully described and claimed.

In the accompanying drawings: Figure 1 is a vertical, transverse, sectional view of the improved burner. Fig. 2 is a top plan view as indicated by arrow 2 of Fig. 1. Fig. 3 is a view in front elevation as indicated by arrow 3 at Figs. 1 and 2. j

' Like characters of reference designate corresponding parts throughout the several views.

The burner comprises a-base 10 adapted to set upon the grate or bottom of the fire box in ordinary stoves either of the heating variety or cooking stove or range, and is provided through the bottom with an opening 11 communicating with a tapered column 12 upstanding from the base 10 and with a supply pipe 13 extending upwardly through the column. The column 12 is provided with a bend or elbow as at 14 and a return bend or discharge 15 directed downwardly and with an elliptical or oval pan 16 disposed upon the base 10 and beneath the opening of the return bend 15. The supply pipe 13 extends upwardly through the column 12 and is provided with a T- coupling 17 above the elbow 14 and with a coil 18 communicating with such T-coupling and also with a T-coupling 19 which in turn communicates with the discharge pipe 20 concentrically disposed within the. discharge 15. The discharge pipe 20 is preferably provided with a cap 21 having an orifice 22 through which fuel supplied through the supply pipe 13 is discharged as a gas directed toward the pan 16, as indicated in Fig. 1.,

It will be apparent that the fuel discharged as gas through the orifice 22 directed toward the pan 16 will, when ignited, ascend about the elbow and the column and into direct contact with the coil 18 by which, as described, the liquid fuel is gasified for furtherdischarge. Air passing upwardly through the opening 11 is in position to cool the supply pipe 13 to prevent back pressure or expansion. After such pipe passes from without the air passage and communicates with the coil 18 such coil is directly subjected to the heat from the pan to vaporize the fuel.

I claim;

1. The combination with a base, of a fuel pan supported upon the base, an air duct having an opening through the base and a return bend upon itself directed downwardly upon the pan, a supply pipe passing upwardly through the air duct, a 0011 upon the exterior of the duct communicating with the supply pipe, and a discharge pipe connected to the coil and entering the discharge end of the air duct concentrically thereof and above the pan.

2. The combination with a base, of a fuel pan disposed thereon, an air duct having a Patented Apr. 2, 1912.

passage through the base and provided with pipe connected to the coil and passing Within an elbow directing the discharge end of the the air duct and disposed above the pan. air duct upon the pan, a fuel supply pipe In testimony whereof I aflix my signature leading upwardly through one section of in presence of two witnesses.
