, T0 all whom t may concern:

Be it known that we, ALBERT J. LINDE- MANN and WALTER C. LINDEMANN, citizens ofthe United States, and residents of the city of Milwaukee, in the county of Milwaukee, Stateof Wisconsin, have invented ce'rtain new and useful Improvements in Hydrocarbon-Burners, of which the following is a specification.

The improvements relate to burners of the fwickless variety, in which an annular trough is provided, and a wick of lasbestos or other non-combustible material placed therein. In such devices it is desirable to obtain a quick and even distribution of the liquid hydrocarbon fuel around the bottom of the wick, and, when the burner is constructed and arranged to be drained, a quick draining of the oil therefrom. Among the objects of the present improvements are the production of a burner trough having these characteristics, of simple construction and effective operation, and to so construct the trough` that it can be manufactured at a minimum of labor and materials.

The improvements are illustrated'in the accompanying drawings, referred to herein, in which Figure 1 is a plan of a burner trough embodying the improvements; Fig. 2 a vertical section of the same on the line 2-2 of Fig. 1, looking in the direction indicated by the arrows, and Fig. 3 a similar section of a fragment of the trough on the line 3-3 of Fig. l, looking `in the direction indicated by the arrows.

The burner trough A is composed of a single piece of sheet metal drawn or otherwise formed into a trough A, with flanges G and II around its upper edges for the reception of a combustion chamber, and a foraminous diaphragm F extending across the central space.

rIhis trough is so formed that its bottom is` inclined toward the fuel supply pipe B from a point diametrically1 opposite said pipe, and at its shallowest point it is prowhich supports the wick C above said bottom at that point. On both sides of the trough near the bottom are lateral indentations D on a level with the upward bottom indentation E, one of these indentations being provided on each side of the trough so that they extend toward the middle of the with a small bottom indentation E,

fore that the wick is supported horizontally above the bottom of the trough while ther bottom of the trough inclines downwardly toward the inlet and outlet opening A leading to the-fuel supply pipe. In this manner a free channel for the influx and distribution and the outflow of the liquid fuel is provided around the bottom of the wick, and the wick is supported in such a manner that its upper and lower edges will be horizontal and will absorb the liquid fuel and carry it up and present it for vaporization evenly throughout its entire circumference. It will also be seen that the trough is made of a single piece of material without additional parts, and that the wick supporting devices are formed by the simple method of producing indentations in its sides and bottom.

' In operation fuel is admitted through the supply pipe B in sufficient volume and runs around beneath the wick, reaching the part of the wick farthest from the supply pipe as quickly as the part immediately above said pipe, and presenting itself for absorption simultaneously at all points. When the burner is drained the level of the liquid fuel falls instantly throughout the entire trough and the flame is thereby reduced at substantially the same rate throughout. The draining of the trough is also quick and complete, and any particles of carbon or other matter that may have found their way to the bottom of the trough are carried off with theliquid and do not clog or obstruct the trough in any way.

What we claim is:

1. An annular trough comprising in its construction a trough proper, composed of sides and bottom, and having an inlet and outlet opening in said bottom, said bottom being inclined upwardly from said opening to a point distant therefrom, a portion of said bottom being elevated at said point, and the bottom inclining downwardly therefrom on both sides to said opening. f

2. An annular trough comprising in its constructiona trough proper, composed of sides and bottom, and having an inlet and outlet opening in said bottom, said bottom being inclined upwardly from said opening tally in saidv trough.

3. An annular trough comprising in its construction a trough proper, composed of sides and bottom, and having an inlet-and outlet opening in said bottom, said bottom being inclined upwardly from said opening to apoint distant therefrom, a portion of said bottom being elevated at said point,

and the bottom inclining downwardly therefrom on both sides to said opening, in combination with a wick device having its bottom resting on said upwardly extending portion of the bottom and supported horizontally in said trough, said wick being out of contact with the said bottom at other points.

4. An annular trough comprising in its construction a trough proper, composed of sides and bottom, and having an inlet and outlet opening in said bottom, said bottom being inclined upwardly from said opening and on both sides thereof to a point distant therefrom, in combination with a wick device having its lower part at the saidV point of the bottom and supported horizontally in said trough, said wick being out of Contact with said bottom at all other points.

5. An annu-lar trough comprising in its construction a trough proper, composed of sides and bottom, and having an inlet and outlet opening in said bottom, said bottom being inclined upwardly from said opening to a point distant therefrom, a portion of said bottom being elevated at said point, and the bottom inclining downwardly therefrom. on both sides to said opening, and said trough also having inward lateral projections between said opening and said upwardly projecting portion of the bottom, saidA lateral projections being above the bottom.

6. An annular trough comprising in its construction a trough proper, composed of sides and bottom, and having an inlet and outlet opening in said bottom, said bottom being' inclined upwardly from said opening to a point distant therefrom, a portion of said bottom being elevated at said point, and the bottom inclining downwardly therefrom on both sides to said opening, and said trough also having inward lateral projections between said opening and said upwardly projecting portion of the bottom, said lateral projections being on a level 'with the upper part of the said upwardly projecting portion of the bottom.

7. An annular trough comprising in its construction a trough proper, composed of sides and bottom, and having an inlet and outlet opening inl said bottom, said bottom being inclined upwardly from said opening to a point distant therefrom, a portion of said bottom being elevated at said point, and the bottom inclining downwardly therefrom on both sides to said opening, and said trough also having inward lateral projections between said opening and said upwardly projecting portion of the bottom, said lateral projections being above the bottom, in combination with a wick device supported horizontally on said upwardly projecting portion of the bottom and said inward lateral projections.

8. A trough comprising in its `construction a trough proper, having an outlet and inlet opening, and a bottom finclined upwardly from said opening, in combination with a `wick device supported above said bottom throughout to leave a space for the free passage of fluid between its lower edge and the said bottom,

9. A hydrocarbon burner device comprising in its construction an annular trough, composed of a single piece of sheet metal and having an inlet and outlet opening at the bottom thereof, wick supporting devices formed by indenting the sides and bottom of the metal forming the trough at different points throughout its circumference.

10. A hydrocarbon burner device comprising in its construction an annular trough, composed of a single piece of sheet metal and having an inlet and outlet opening at thevbottom thereof, wick supporting devices formed by indenting the sides and bottom of the metal forming the trough at different points throughout its circumference, and flanges at the upper edges of said trough extending outwardly' and upwardly "therefrom, formed of the same piece of sheet metal as the trough.
