ens GENERATOR AIND LAMP.

To all whom it' m ay concern Be it known that I, ROBERT L., Domma cit zen of the, United States of America, and

' a resident of Chicago, in the-county of Cook and State of Illinois,- have invented certain new and useful Improvements in Gas Generators and Lamps,- ofwhichthe following is a specification.

The main objectotmy invention is to provide an improved gas generator and lamp in- .which an inverted mantle is usedto throw the light 1 downward and outward without obstruction, so as .to produce a shadowless light which can be made portable and readily set up or attached in placeswhere anincandescentlight is wanted andwhich are not. provided with the ordinary gas orelectric light fixtures. Thisobject is accomplished by the device shownln the accompanyingd'rawings, in which: v I I Figure 1 is a vertical section of a generatorand-lamp constructed according to this invention. Fig, 2 is an enlarged vertical sec- 7 tion of the lower end of the generator. Fig.

3 shows a vertical section of the needle valve 8 which controls the supply of fuel to the va orizer. 1 a

' n the form sliown,'the casing'l has anair tube 2 extending horizontally. through the same. Said tube 2 has the u per interiorly threaded extension 3 having t readed therein the gas tip 4 which has the discharge 'ori- 'fice 5; A layer of gauze dextends across said tip 'at the lower end of the generator pipe or chamber 7 which is threaded into said gas tip '4. The generator'chamber or 'vapoe rizing tube 7 has aneedle valve or shut-off. valve 8 at its upper part' The canopy 9 has I the erforated-s'lde walls 10 and rests loosely in t e flared art 11 of the casing 1.1 The perforated -wa l 10 has an aperture 12 therein of suificient size to permit alcohol'to be injected through. a tubejinto the asbestos-retaining cup 13 or starter-lamp. Said cup 13 is made in the form of an annular trough surrounding the lower end of the enerator ithin the tube 2 is a slidevalve 14 for. shutting off the discharge of gas fromthe orifice' 5. The gas tube 15 is connected to andextends, down:

wardly from the air tube -2 and has threaded thereto an extension 16 from which is suspended the Inant1e'17. Said mantle isat- .tached to, the ring" 18-which connects by means of arms"19 with the cap20. Said cap perf0rated-;at"21,. and is attached to the Specification of Letters Patent.

-.The operation of the device shown is as follows:.Gasolene is injectedinto the gener ator chamber, 7, under pressure, through the usual'.wircfee( l, and the flow into said chamber'is controlled by the valve 8. Before the. valve 8 is opened so as to permit the flow of gasolene or other-gas forming liquid into. the chamber 7, the asbestos 28 contained inthe cup13 will be soaked with sul'licient alcohol v This may be ignited either through the orifice 12 or by lifting the cano y' 9. When the chamber 7 is suflicient yheated, the valve 8 is opened. The

- gas generated -in the chamber 7 passes through the orifice 5am] down into the tube 15 in the direction of the arrows, then through the mantle 17, and upwardly within the casing 1, around the'air tube 2 and is there ignited by the flame at the cup 13.' This causes the ignition of the gas at the mantle 17 in the usual manner. The heat in the upper part of the casing 1 causes an upward draftof air in the casing. This draws the air into the tube 1 2,where it mixes with the gas and passes'down through the tube 15 and through the mantle. The tubes 2 and 15 together with the gas tip '6 form a Bunsen bu'rner which provides suificientair to heat the-.mantleto 'incandescence. To shut oi? the gas and light, the valve 8 is closed and the slide valve 14' is pushed inwardly to close the orifice -5.- The, closing of the valve 14 shuts oil? the gas so as to immediately eX- tihguish the flame. If the valve 145 should be left open, the small quantity of gas passing from the generator chamber 7 would cause the mantle to burn red and to'blacken in parts while said gas isbeing exhausted from the generaton- The generator being directly above-and within the heating zone of the mantle, continues the generation of gas so lon 'as the valves 8 and 14 are 0 en, and while the gas is-burning at the mant e.

Since the mantle, mixing tube, and generating ,or vaporizing tube are all in the same- Vertical lineand co-axi'al with.e-ach other, and since the casing is coaxial with all of said parts, a great efiiciency is obtained both in heating the generator and in preheating the gas as it passes down through the mixing tube. The casing guides .the heated air from the burner vertically along the mixing wardly from-said vaporizin tube and coand vaporizing tubes, and distributes the axial therewith, an mverted mantle sursame equally upon all sides of said tubes.

The advantage of having the casing removably secured to the vaporizing tube, and having all of the other parts of the lamp secured to and suspended within thecasing, is that the casing and attached parts of the lamp may thus be taken down for the purpose of cleaning or repair without detaching the vaporizing tube from its connection with the reservoir for the hydro-carbon liquid.

What I claim as my invention and desire to secure by Letters Patent is:

1.. A gas lamp and generator comprising a l l l rounding the lower end of said mixing tube and co-axial therewith, a casing surrounding said tubes and mantle, concentric therewith, and adapted to convey the heat from said mantle upwardly along the vaporizing tube, and an air inlet leading" from the outside of the easing into said mixing tube.

4. A gas generator and lamp, comprising in combination a vertical vaporizing tube, an

air inlet below the end thereof, a burner tube vertical vaporizing tube, a Bunsen burner suspended below, and in vertical line with said va'iorizing tube and communicating therewit 1, an inverted mantle suspended from and surrounding the lower end of said Bunsen b11111? 1 and being in the vertical line of said vaporizing tube, and a casing surrounding said vaporizing tube and Bunsen burner and adapted to conduct the heat from said mantle vertically along said vaporizing tube.

2. A gas lamp and generator comprising a vertical vaporizin tube having at its upper end a valve-contro led liquid inlet, and at its lower end a valve-controlled gas outlet, a vertical gas mixing tube extending downwardly from said vaporizing tube in vertical line therewith, and having its upper end op on so as to admit 'air from outside of said vaporizing tube, and a mantle surrounding the lower-end of said gas tube, and being in the vertical line of said vaporizing tube.

- 3. A gas lamp and generator comprising a vertical vaporizing tube having at its upper end a valve-controlled liquid inlet, and at its lower end a valve-controlled gas outlet, a. vertical gas mixing tube extending downi, in axial alinement with said vaporizing tube, an inverted mantle depending troin the lower end of said burner tube in axial alinement therewith, and a casing surrounding said tubes and adapted to conduct heated air from said burner and mantle along said vaporizing tube, said vaporizing tube being provided with means for regulating he fl w of liquid fuel into its upper end and means for regulating the discharge of gas from its lower end.

5. A gas lamp and generator comprising a vertical va orizing tube, a Bunsen burner suspended elow and in vertical line with said va orizing tube and communicating therewit 1,, an inverted mantle suspended from and surrounding the lower end of said 1 Bunsen burner and being in the vertical line of said vaporizing tube, and means at the top of said vaporizing tube adapted to introduce liquid fuel into said tube in minute quantities adapted for immediate va orization by the heat rising from said mant .e.
