SPECIFICATION forming part of Letters Patent No. 660,528, dated october 23, 1900.

l Application filed March 7, 1900. Serial No. 7,654. (No model.)

To a/ZZ whom t Hetty concern:

Beit known that I, JOHN J. DUNLAP, a citizen of the United States, residing at Canton, in the county of Stark and State of Ohio, have invented certain new and useful Improvements in Incandescent Vapor-Burners; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, making a part of thisspecification, and to the figures of reference marked thereon,'in which- Figure l is a side elevation. Fig. 2 is a vertical section. Fig. 3 is a detached View of the gas-tip, needle-chamber, and connecting section or part. Fig. 4 is a top view. Fig. 5 is a detached perspective view of the gastip and its parts. Fig. 6 is a transverse section on line fr, Fig. l, except the chimneyholder is shown removed. Fig. 7 is a top View of the part shown in Fig. 5.

The present invention has relation to incandescent vapor-burners; and it consists in the dierent parts and combination of parts hereinafter described, and particularly pointed out in the claim.

Similar numerals of reference indicate corresponding partsin all the figures of the drawings. f

In the accompanying drawings, l represents the body, which is substantially of the form shown` and, as shown, it is provided with the Vaporizing- passages 2 and 3, which passages are located substantially as shown, and, as shown,they converge toward their upper ends and are united at the upper limit of said passages, and for the purpose of increasing the vaporization the upper portions of said passages are located through the bars 4., said bars being formed integral with the body and are located within the chamber 5, as illustrated in Fig. 2. Upon the top or upper end of the chamber 5 is located the convexe-concave gauze disk 6, through which disk extends the head 7, which head is located upon the joined portions of the bars 4 and is for the double purpose of providing a body of metal directly over the point where the passages 2 and 3 come together and above the point where the fuel changes its upward How to a downward iiow.

By extending the head-7 through the gauze disk 6 and a short distance beyond the top or upper side thereof the flame will be shunted toward the inner periphery of the mantle 8, by which arrangement a better light is produced.

For the purpose of conveying the fuel to the gas-tip 9 the vertical pipe or tube l0 is provided and is connected at a point directly below the bottom or lower end of the passage 3.

The bottom or lower portion of the pipe or tube lOis provided with the horizontal portion l1, which horizontal portion 11 is provided with thepassage 12, said passage leading to the tip 9. Directly below the tip 9 is located the needle 12', which needle is for the purpose of regulating the flow of gas.

'The feed-pipe -13 is connected to the body l in the ordinary manner and may be provided with a valve or cut-off 14, said valve or cut-oif being particularly shown in Fig. .1.

For the purpose of surrounding the gas-tip 9 the housing l5 is provided, which housing is supported in the usual manner.

Within the housing l5 is located a short tube 16, which tube forms a guide for the fuel after it has passed the tip 9.

For the purpose of preventing air from entering at the side of the housing at the place where said housing overlaps the pipe or tube 10 said pipe or tube is provided with the laterally-extended flanges 17. Said lianges are formed of a shape to correspond, substantially, with the form of the housing 15.

It will be understood that by locating the head 7 in the center of' the gauze disk and directly over the vertical center of the cylinder the flame will be more equally distributed, by which arrangement the same volume of flame will be around the head, by which arrangement a more even and uniform light is produced.

The thixnble 16' is located within the tube or mixing-chamber 16 and is held in proper relative position by frictional contact.

The head 7 is located in the center of the gauze disk 6, a portion of said head being above the disk and a portion below the disk, and is so located for the purpose of better heating the head, and at the 'same time by .providing the con vexo-concave disk the flame is shunted toward the inner periphery of the IOC mantle. Another object and purpose of 1ocating the head as described is to provide for turning the light down or, in other words, reducing the supply of fuel, and yet provide sufficient heat to maintain a small light and at the same time produce sufficient heat to generate or Vaporize a sufficient amount of gas to maintain the light when turned down. Heretofore the light when reduced in volume would not produce sufficient heat to maintain the light when reduced.

Having fully described myinventon, what I claim as new, and desire to secure by Letters Patent, is-

A body provided with a chamber at its upper end and having up and down passages formed in its lower portion, a conveXo-concave gauze disk covering said chamber, bars projecting inwardly across said chamber and having passagesformed therein which continue the up and down passages in the body, and a head formed at the meetingof the bars Aand lying above and below the gauze disk,
