GASOLEN E-LAM P.

SPECIFICATION forming part of Letters Patent No. 732,686, dated June so, 1903.

Application filed April 12, 1902.

To all whom. it may concern.-

Be it known that I, JAMES J. FLINT, a citizen of the United States of America, residing at Denver, in the'count'y'of Arapahoe and State of Golorado, have invented certain new and useful Improvements in Gasolene-Lamps; and I do 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, reference'being had to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification.

My invention relates to improvements in gasolene-lamps; and it consists of the features, arrangements, and combinations hereinafter described and claimed,.all of which will be fully understood by reference to the accompanying drawings, in which is'illu'strated an embodiment thereof. 1

In the drawings, Figure 1 ,isaside elevation'of the lamp,-partly"in section. Fig. 2 is a section taken through the generator and'a portion of the lamp-frame, shown on a larger scale. Fig. 3 is a similaryiew illustrating a modified form of construction. Fig. 4 is an enlarged fragmentary section taken through the reservoir. Fig. 5 is a fragmentary section taken through the lamp-frame, illustrating the shut-off valve. Fig. 6 is a section taken through the central tube connecting the two parts of the reservoir. Fig. 7 is adetail sectional view, on a larger scale, showing the screw-plug and valve constructionillu'sp trated in Fig. 4:.

The same reference characters indicate the same parts in all the views. Let the numeral 5 designate the reservoir, which is composed of two semispherical members 5 and 5, connected by a central vertical tube 6, whose extremities are threaded to receive nuts 7 and 8, respectively. The nut 7, applied to the lowerextremity of the tube, is countersunk in the bottom of the reservoir, while the. nut 8 protrudes at the top and is exteriorly threaded to receive a cast bracket 9, which is screwed thereon. Aburner 10 is mounted on this bracket and communicates with a passage 12, leading from a tube 13, forming a part of the lamp-frame. -A passage 14 in this bracket communicates at one serial No. 102,671. (No model.)

extremity with a tube 15 of thelamp-frame located on the opposite side of the burner from the'tube 13, making the lamp symmetrical. A shut-0E- valve 16 is screwed into a casting 17, interposed between the parts of the frame-tube 15. This casting is provided with an' irregular passage 17 ,which may be opened and olosedat pleasure by turning the valvestem,"whereby the gasolene maybe cut off from or allowed free passage to the generator, as maybe desired. v

The upper extremity 15 of the frame-tube 15 is madeheavier than the body of the tube and provided with a threaded opening, into which is screwed a nipple 18, applied to or formed integral with one extremity of the generator-tube 19. This nipple is interiorly threaded to receive the threaded portion of a valve-rod 20 of the generator. The upper extremity of the tube 15 is also provided with v a projection 15", bored to communicate with the tube and forming a guide for the rod 20, which passes through a stuffing-box 21, applied to the said projection. The threaded portion of the rod 20 is provided'with a groove 20, through which the gasolene passes from the frame-tube 15 to the generator-tube, in which is located a needle 22 of the valve-rod. The tube 19 is located directlyabove the burner and the exit extremity thereof, where the gas escapes discharges into an air-bell 23,

mounted on and located directly in front of 7 5 This bell is formed larger than the tube 13 to the open upper end of the frame-tube 13.

ermit air to mix freelywith the gas'in the said tube, whereby the gas is supplied with the necessary oxygen for illuminating purposes before passing to the burner.

Connected with the upper extremities of the tubes 13' and 15 is a hanger 24, provided at its upper extremity with a suspensionhook 25.

The reservoir-tube 6 is provided with a wire-gauze or other suitable packing 6, forming a strainer for the gasolene, which passes to the tube through an opening 6, formed in the lower portion of said tube.

Inserted in an opening formed in the member 5 of the reservoir is a filling-tube 26.

The outer extremity of this tube is normally. 1

closed by a screw-plug 27, provided with a valve 28, adapted to be connected with an down on the reservoir air-pump (not shown) for the purpose of compressing the air within the reservoir above the gasolene, whereby the latter is forced through the opening 6 into the tube 6 and thence up through the packing therein,where the liquid is relieved of its impurities, and thence through the passage 14,- and up through the frame-tube 15 to the generator, Where it is heated and converted into gas while passing through the generator-tube by the flame from the burner below. The gas generated in the tube escapes to the air-mixing bell 23 and passes thence downwardly through the frame-tube 13 and through the passage 12 to the burner, which is equipped with a \Velsbach mantel.

In the construction shown in Fig. 3 the generator 19 is formed heavier than the corresponding element shown in Fig. 2, and a reduced tube 19 is screwed thereinto.

While, as shown in the drawings, the airbell is mounted on the upper extremity of the frame-tube 13, it may be mounted on the adjacent extremity of the generator-tube with equally good results. Hence I do not limit the invention to any especial manner of mount ing the air-bell.

The inner extremity of the valve 28 is coneshaped or beveled to fit a seat of corresponding shape in the plug 27. Above the bevel or outside of the latter the valve is reduced, as shown at 28, and a passage-way 28 through the valve terminates at such reduced portion, whereby when the valve is seated communication with the reservoir by way of the passage-way 27 in the screw-plug is cut off. As soon, however, as the valve is moved outwardly from its seat air may be forced into the reservoir by connecting the nipple of an air-pump with the screw-threaded socket 28 at the outer extremity of the passage 28 of the valve.

Having thus described my invention, what I claim is- 1. Ina gasolene-lamp,the combination with a lamp-frame, of a reservoir composed of two parts, a central tube connecting the two parts, nuts applied to the tube extremities for fastening the said parts together, the tube having an opening communicating with the reservoir below the liquid, and its upper extremity being open to allow the liquid to pass to the lamp-generator, substantially as described.
