` Application filed June 8, 1897. Serial No. 639,919. (No model.)

.To all whom it may concern.-

Be it known that I, J QHN F. WILI.IAMS,-` a citizen of the UnitedStates, residing at Kansas City, in the county of Wyandotte, in the State of Kansas, have invented certain new and useful Improvements in GasGenerating I p Gas-Fixtures, of which the following is a full,

clear, and exact description, reference being had to the accompanying drawings, which are made a part of this specification.

lWIy invention relates to improvements in gas-generating gas-iixtures in which, in passage through the fixture, the gas is generated from liquid hydrocarbons, is mixed with a suitable quantity of air, and delivered to the ignition-tube Without the interposition of any of the usualforms of generators or burners; and my invention consists in certain features of novelty hereinafter described, and pointed out in the claims.

Figure I represents a gas-fixture embodying my invention. -Fig.lII represents a longitudinal cross-section of the generating-tube and its cooperative parts. Fig. III represents a cross-section of. theignition-tube. Fig. IV representsa modified form of tip for the generatingtube. Fig. V represents a view in cross-section of a preferable means of l forming the tapering passage in the vaporizingtube; and Figs. VI, VII, and VIII, views illustrating modiiications and variations hereinafter referred to. y

Similar numerals refer to similar parts throughout the several views.

1, 2, 3, and 4 represent the tubing or pipes forming the fixture, connected by YtheTs 5, G, 7, and 8.

9 represents a tube or pipe passing through the vessel 10, containing a supply of liquid hydrocarbon and connected with the fixture by the T 7. Vithin said vessel said tube is provided with one or more openings covered by the gauze screen 11 for Aadmitting the liquid to the tube and thence tothe fixture, the screen serving to prevent the admission of extraneous matter, the sides of said vessel being partly broken away to show the same. Said tube, extending above said vessel, may be attached toaI Wall or ceiling-hanger or other convenient support.

The tubes 9 and 4 constitute the supplytube.

12 represents the vaporiZing-tube, connect-- ed With the supply-tube l through the T 6 and provided with the shutoff valve 13. It Will be observed, as shown in Fig. II, that the passage through said tube diminishes from the heavier or unvaporized particles and pre vent clogging of said opening thereby. The

heavy or unvaporized particles naturally tend to adhere to the inner Walls of the tip 14 and to travel therealong toward the dischargeopening, but the collar 17 arrests them and prevents their discharge. 18 represents a sleeve surrounding said tip provided With the openings 19, arranged to slide on the tube 20,

connected with the T 5 and adjustable theref on by the set-screw 2l, the purpose of said sleeve being to regulate the air-supply admitted to mix With the vapor issuing from the tip. In operation the tube or sleeve 18 should not come into direct contact With the tip, for should such contact occur theheat would be drawn from the tip and the tip thereby cooled.

The pipe 1 forms the mixing or diffusing tube, connecting through the T 8 with the tube 22, leading to the burner 22A.

23 represents a chimney-holder formed With the sleeve 24, arranged to slide over the tube 22 and rest upon the shoulder 25 thereon. 26 represents a cup formed on said sleeve. represents a sleeve arranged to be fitted Within said cup and-provided with the gauze Screen 2S, forming the burner.

29 represents the chimney,the arrangements of the parts being such that the vaporizingn tube extends across the line of the chimney a short distance above the same.

30 represents a chimney-support.

31 representsan envelop or mantle of refractory incandescing material arranged to surround the flame and form an incandescent mantle around the same. I 2 represents a support for said mantle. 38 represents a setscrew for adjusting the Slle.

yIn Fig. IV is shown a :modification 'of the coupling and tip shown in Fig. II, which I preferably use when a fixture Withmore than one light is desired. In such case I provide the coupling 15 with the head 34, having `the IOO openin gs 35 for the passage of the vapor from the vaporizing-tube to the tip and having the needle point 36 set therein and extending through the openingl in the tip, the arrangement being such that by adjustment of the tip upon the coupling the fiow of vapor throughy a tube having a straight passage by placingv therein a rod 37, filed or dressed to'form such tapering passage, as shown. The rod is simply held in place by frictional contact and may be readily Withdrawn when it is desired or may become necessary to clean it.

When a fixture with more than one light is desired, arms 38 (shown in dotted lines in l Fig. I) may be supplied, provided With-burners similar'to the one shown, all said burners being supplied from the mixing-tube 1.

In operation my improved apparatus is exceedingly simple. rlhe liquid hydrocarbon passing from the vessel 10 through the tubes 9 and 4 to the vaporizing-tube 12 is there Vaporized by the heat from the flame concenproXimity under said tube. The tube 9 being larger than the tube 4 and the tube 4 larger than the vaporizing-tube and the passage in the vaporizing-tube decreasing in size from inlet to outlet, it is apparent that by reason of the constant decrease in size of the passage from the inlet of the liquid into the pipe 9 to the exit of the vapor from the vaporizing-tube any back press-ure in the tubes generated during the process of vaporzatiou meets the least possible frictional resistance, and the exit of the vapor will be steady and cannot puff and blow and cause uneven pressure. In other Words, by the arrangement and construction of the passages as shown, but leaving them otherwise clear of any packing or filling material, the particles or molecules of the liquid as they expand or are converted into gas ymay exert their pressure in a rearward direction and not tend, as in the usualv burners, to force the gas out through the tip under uneven impulses. The vapor passing from the vaporizing-tube passes through t'he opening in the tip 14 into the air-supply chamber formed by the sleeve 1S, the expansion of the vapor in the coupling tending further to promote a continuous and steady fiow of the vapor from the tip, the collar 17 'Within the tip preventing foreign matter from reaehingthe opening and clogging the same. By adjustment of said sleeve 18 0n the tube 2O the amount of air admitted is regulated and controlled, the air entering through the holes19 and at the space between the sleeve and coupling, as shown by the a1'- rows in Fig. II. passing through the tubes becomes thoroughly mixed in passage and passes to the Thence the air and vapor burner through the tube 22, andY by surround- 'ing the flame with the incandescing mantle I obtain by this simple and cheap apparatus a very brilliant and powerful light.

Among .the advantages gained by my improved apparatus may be mentioned the simplicity of its construction, a constant and even pressure from the source of supply to and through the vaporizing-tube, a constant and even' heat upon the vaporizing-tube resulting in constant and even vaporization, the perfect control ofthe air-supply, and the constant and perfect mixing and diffusionof the air and vapor before reaching the point of ignitiomand there being few parts and all simple and easily accessible it is little liable Y to get out of order, and any failure-of the parts can be easily remedied.

I have preferably arranged the vessel and tube in the relation shown in Fig. I; but it is apparent that the vessel may be put on the side of the pipe, as shown in Fig. VI, or, as i shown in Fig.VIII,the vessel maybe supported and arranged in any convenient manner and have a pipe 40 run along the ceiling-or other `place and one or more fixtures connected to v the same Without departing from the princi- Y pal construction shown.

trated through the chimney arranged in close The fixture can be varied in construction in many Ways-as, for instance, as shown in Fig.

VII, I could leave out pipes land 3 and putin an L at 8in place of the T, letting the tube y 12 pass over and back across the chimney and discharge the generated gas and air -into pipe 2, making a mixing-chamber of Yit the same as with pipe 1. So, too, instead of passing the vaporizing-pipe 12 directly over the chimney I may place it lower down and pass it around the chimney, such construction being shown in the burner upon the left of Fig. VIII.
