SPECIFICATION forming part of Letters Patent No. 768,642, dated August 30, 1904. Application filed January 14,1904. Serial No. 188,945. (No model.)

To all 1071,0777, it may concern:

Be it known that I, WILLIAM TUREs, a citizen of the United States, residing at Granville, in the county of Putnam and State of Illinois, have invented a certain new and useful Improvement in Lamps, of which the following is a specification.

for burning.

Figure 1 is a side view of a lamp with parts broken away to show portion of my invention. Fig. 2 is a cross-section on the line 2 2 of Fig. 1.

Like parts are indicated by the same letter in all the figures.

A is the body of the lamp, the lower portion of which is to be filled with the liquid, and this may be done by removing the plug B.

two ways D E, connected therewith. The valve O is adapted to be operated to close or open either or both of these ways. Any sort of valve suitable for this purpose can be employed. Moreover, two valves could be employed, one to control each way.

F is a tube leading from the way E and terminating in the nozzle G.

H is a pipe shown in dotted line as within and A. This pipe is shown in the same vertical plane as the plug B; but it is placed, preferably, in the middle of the lamp, so as not to interfere with said plug. It extends up and forms one side J of the frame and continues to a point above the burner K, where it finally terminates in the discharge-aperture L, surrounded by the cup M. This discharge-aperture is partially controlled by a needle-like projection M on the end of the valverrod N, vhich passes through the stufling-box P and 1S controlled .by the handle R, and is provided with a valve O, adapted to engage the seat O in the upper end of the side J of the frame. The pipe H is preferably screw-threaded on its exterior and lined inside by a gauze-like tubular body. S is the other side frame of the lamp, opposite the tube J, but similar invention relates to lamps such as em-' ploy hydrocarbon by converting it into gas.

contains a valve 0 andv extendingto the bottom of the lamp-body the direction indicated by the as follows: The plug may be removed and the I reservoir be filled approximately half-full of hydrocarbonas, for example, gasolene. The plug may be then put in place and the airpump appliedto the way D, and thus the reservoir be charged with air to any desired 5 pressure. The valve O is then manipulated to close the way D. When it is desired to use the lamp, the valve O is manipulated until the pipe F-communicates with the chamber in the lampbody A. The vapor-charged air in the up- 7 per part of the reservoir will now pass up the pipe F andinto the two arms of the nozzle G. A match applied to these arms will light the gas, and there will be a row of flames on each side'of and somebelow but projected up- Wardl y and inwardly toward the pipe H. Since the pipe H is open at its discharge-aperture L and closed at its other end, it will be filled with air, which is quickly heated to high temperature. lated, the valve may be slightly unseated, and a small quantity of hydrocarbon will be forced up into the pipe H,'Where it begins to flow through the pipe H toward its discharge- If now the handle R be manipuaperture. Passing among the meshes of the S gauze-like cylinder it is quickly and uniformly converted into gas and passes out in arrow into the tube S and thence into the burner of the lamp, where it is fired. The valve C may manipulated to cut off the starting-nozzle and the lamp will continue to work. The nozzle presents no obstruction to the action of the heat'of the lamp upon the pipe H. It has no then be 9 supply of air from the atmosphere, no screens or other distributing media.

Its dischargeing a uniform action.

holes are faced on opposite sides of the two branches and discharge toward each other, thus insuring a continuous combustion. The heat of the starting-nozzle is very uniformly distributed over the pipe H, and thus secures quick action in such pipe, both for preparing the same for the introduction of the liquid hydrocarbon and for the conversion of the latter into gas. The pipe in which this conversion talies place is always dry and filled with air. It gives a very uniform and perfect supply of gas without any quivering or any irregular action of the illuminating-flame. The gauze distributes the liquid, increases the heating metallic surface and assists in secur- The pipe H is always open at one end, and there is therefore never any danger of explosion by the heating of the confined body of the liquid hydrocarbon. The exterior screw-threads on the pipe H are to quicken the heating action.

Iclaim 1. In a hydrocarbon-lamp the combination of a burner, afuel-reservoir, a screw-threaded vaporizing device with a tube of gauze mal terial therein and placed above the burner, and a starting-nozzle connected with the reservoir and having two branches disposed so as to act upon the vaporizing device to start the action of the same without subsequently intercepting the heat from the burner.

2. In a hydrocarbon-lamp the combination of a burner, a fuel-reservoir, an exteriorlyscrew-threaded vaporizing-tube open to the atmosphere at its discharge end, and located under the burner, a tube of gauze-like material within such vaporizing-tube, a startingnozzle having two apertured branches, such nozzle being connected with the reservoir and so disposed as to act upon the vaporizing-tube to start the action of the same without subsequently intercepting the heat from the burner, a valve for controlling the flow of fluid from the reservoir to the vaporizing-tube, and a valve partially controlling the discharge of fluid from such vaporizing-tube.
