LINTON D. LANDRUM, OF COLUMBUS, MISSISSIPPI.

LAMP-BURNER.

Specification of Letters Patent.

Patented Dec. 18, 1906.

Application filed April 3, 1906. Serial No. 309,638-

To a, w/tom it may concern:

Be it known that I, LINTON D. LANDRUM, a citizen of the United States, residing at C- lumbus, in the county of Lowndes and State of Mississippi, have invented certain new and useful Improvements in Lamp-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.

My invention relates to compound lampburners, and more particularly to that class wherein a multiplicity of wicks are used to multiply the brilliancy of the light.

The object of my invention is to so construct the burner that all the gases created in the bowl of the lamp will be directed in con tact with the flame and consumed.

A further object of my invention is to provide a duct for conveying the fumes from the bowl up through the burner and deliver them in direct contact with the flame.

A still further object is to provide a burner that will thoroughly mix the gases with hydrocarbon, whereby kerosene of an inferior quality may be used and the foul gases and grease arising therefrom consumed without escaping into the room.

Other objects and advantages will be hereinafter pointed out in the specification and referred to in the claims.

In the accompanying drawings, which are made a part of this application, Figure 1 is a perspective view of my improved burner, a portion of the flame-cap being broken away. Fig. 2 is a central transverse section through the burner. Fig. 3 is a sectional view as seen from line 3 3 in Fig. 2. Fig. 4 is a sectional View, on an enlarged scale, as seen from line 4 4 in Fig. 3 and Fig. 5 is a plan view of the fume-conveying tube.

In the drawings similar numerals indicate like parts throughout.

1 indicates the body of my improved burner, and 2 the chimney retaining members, which are of the usual well-known form. Rigidly secured to the body portion 1, as by soldering or otherwise, is a cap 3, said cap being provided with a covering 4, said covering being hinged to the cap, as best shown in Fig.

2 of the drawings. By providing the cap of this construction and making the same solid with the burner, so that the air from the outside cannot get into said cap, a combustionchamber is formed. This cap is provided with openings 5, preferably four in number, through which the flames are directed.

Passing up through the bottom 6 of the burner are wick-tubes 7, said tubes being preferably arranged to radiate from a common center and normally resting at right angles to each other. These tubes are spaced apart at their inner ends, and in this space is disposed a tubular member 8 of the same height as the wick-tubes and extending downwardly through the bottom 6 and into the bowl of the lamp, so that any fumes or gases accumulating in the bowl of the lamp will be directed into contact with the flames on the upper ends of the wicks 9. The upper end of the tube 8 is closed, and said tube is provided at this point with auxiliary tubes 8 said auxiliary tubes extending into close proximity to the several tubes 7, whereby the fumes and gases will be delivered directly into the flames.

In the construction herein shown I employ two separate devices 10 and 11 to operate the wicks and direct them upwardly or downwardly, said members comprising a thumb-wheel 12 and toothed members 13, said toothed members being directed through suitable slots 14 in the tubes 7 and into engagement with the wicks 9. I/Vhile I have shown but two of the wick-directing'members, it will be understood that a device of this class may be employed for each wick, if desired. A solid partition-wall is disposed between the upper ends of the tubes 7 and the bottom member 6, so that outside air or gases cannot be directed into the cap 3 from below, and as the bottom member is also solidly constructed all gases accumulating in the bowl of the lamp will be directed either through the wick-tubes 7 or the tubular member 8. By this construction if it is desired to have a very dim light but one of the wicks may be lighted, and likewise when all of the wicks are lighted a very brilliant light is produced. The amount of illumination may also be controlled by raising or lowering the Wicks in the tubes 7. It will also be noted that one set of wicks can be operated independently of the other set. It will further be understood that the construction of the solid burner and the tubular member 8 can be used with equal success in connection with tubular wicks, if desired. By providing a solid burner and so arranging the same that all the gases will be directed into contact with the flames at the upper ends of the wicks a very brilliant light will be produced and one equal in intensity to an electric light and all of the gases arising from the oil consumed before they have a chance to escape into the room.

That I claim is 1. The herein-described burner comprising a body portion, a cap rigidly secured to said body portion, a covering having apertures therein and hinged to said cap, wick-tubes carriedby said burner, wicks located in said tubes, means to control said Wicks and a tubular member disposed centrally in said burner and between the wick-tubes.

2. The herein described burner comprisin a solid body portion, a cap secured to said body portion, a covering for said cap having openings therein, a partition-Wall at the lower end of said cap, wick-tubes extending through said partition-wall, wicks in said tubes, -a bottom member on said burner and a tubular member extending through said partition w-all and bottom and auxiliary tubes at the upper end of said tubular member whereby gases accumulating in the bowl of the lamp will'be directed to the upper end of the wick-tubes.

3. In a burner of the class described comprising a solid body portion, a cap in the upper surface thereof, a covering for said cap having openings therein, a tubular member centrally located in said burner and extending downwardly therefrom, auxiliary tubes at the upper end of said tubular member, a plurality of Wick-tubes disposed around said tubular member, wicks in said tubes and means for raising or lowering said wicks, a

, solid bottom member secured to said burner LINTON D. LANDRUM.
