INCANDESCENT WIGK-LAMP.

Specification of Letters Patent.

Patented May 27 1913.

Application filed August 21, 1908, Serial No. 449,579. Renewed March 4, 1912. Serial No. 681,610.

To all whom it may concern:

Be it known that I, JOSEPH I-Innzoe, of the borough of Manhattan, city, county, and State of New York, have invented a new and useful Improvement in Incandescent Vick-Lamps, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, in which Figure l is a sectional elevation of my improved mantle and support in place, and Fig. 2 is a perspective view of the mantle and its support.

My invention relates to kerosene lamps and is designed to provide an improved burner, mantle and support which will enable a kerosene burner to be used with a mantle, the heat from the burner raising the mantle into incandescence.

The invention consists in providing a device for changing yellow flame to blue flame, and also a system of supporting the mantle for preventing soot.

In the drawings, 2 represents the wick tube, which is annular in form and tapered toward its top. This tapering presses the tubular wick firmly together in its upper portion, so that when the burner is heated there is no space for sucking up the kerosene. The combustion is produced from the vapor, this vapor being formed by the action of the heated tubes 011 the liquid in the wick.

The inner wall of the wick tube extends slightly above the outer wick tube, as I find that this insures an even burning of the wick. In the gallery are secured the lower ends of supporting wires 18 which extend upwardly and are provided with inwardly bent or hooked portions 19 engaging lugs 20 on a supporting ring 21. This ring may be of any suitable material, such as magnesia, nickel or platinum, and to it the upper open end of the mantle is secured by tying with an asbestos string, or in any other suitable manner. In the present form the mantle 22 is shorter than the height of the wires, and its lower end engages a supplementary mantle cap 23, which is well above the upper end of the wick. The height of the mantle above the wick can be adjusted by telescoping the supporting wires within their lower sockets in the gallery, they being held in their desired oosition by friction within the sockets. ith this mantle I preferably use the kerosene burner shown in my co-pending application filed August 21, 1908, Serial No. 449,578, for improvement in incandescent lamps. By thus providing a free open space be tween the top of the burner tube and the lower end of the mantle I provide for supply of cold air to the top of the Bunsen flame. The mantle is preferably about one half or three-quarters of an inch above the burner cap, and by the supply of air in this space, all soot formation is avoided and no spent air can get access to the blue flame.

The advantages of my invention result from the provision for supporting the lower end of the mantle above the mantle cap, with a space for the entrance of air between.

Variations may be made in the form and arrangement of the burner, mantle and support without departing from my invention.

I claim:

1. In an incandescent wick burner, a mantle support carrying an upper ring to which the mantle is secured and a supplementary mantle cap the upper end of which is located within the mantle, said supplementary mantle cap being spaced above the burner cap to allow the entrance of air therebetween, the mantle support being adjustable to regulate the said distance.

2. In an incandescent wick burner, aburner cap, a supplementary cap located thereabove, the upper end of which is adapted to enter and hold apart the lower end of the mantle, and means for regulating the distance between the burner cap and the supplementary cap.

3. In an incandescent wick burner, a mantle support having spaced apart side wires or rods carrying an upper ring to which the mantle is secured, the lower end of the mantle being spaced above the burner cap to allow the entrance of air between them, and means to hold the lower end of the mantle open; substantially as described.

4. In an incandescent wick burner, a mantle support having spaced apart side wires or rods carrying an upper ring to which the mantle is secured, the lower end of the mantle being spaced above the burner cap to allow the entrance of air between them, the Wires being adjustable to adjust the burner cap to allow the entrance of air 10 the space for the entrance of air, and means between them; substantially as described. to hold the lower end of the mantle open; In testimony whereof, I have hereunto set substantially as described. my hand.

5. In an incandescent Wick burner, a mantle support having side ires or rods carrying an upper ring Within the mantle WVitnesses: and to which the mantle is secured, the C. P. BYRNES, lower end of the mantle being spaced above A. E. WALLACE.

JOSEPH HERZOG.
