VAPOR-BURNING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 663,678, dated December 11, 1900s Application filed April 29, 1899.` Serial No. 714,982. (No model.)

To LZZ whom it may concern,.-

Beit known that I, ARTEUR KITSON, a subject of the Queen of Great Britain, and a resident of Philadelphia, county of Philadelphia, State of Pennsylvania, have invented certain new and useful Improvements in Vapor-Burning Apparatus, of which the following is a specification.

My invention relates to vapor-burning apparatus, and is more specifically designed to produce an improved form of single-burner apparatus for burning the vapor of kerosene or other fluid hydrocarbon mixed with air under the ordinary form of incandescent mantle.

The preferred form of myapparatus is illustrated in the accompanying sheet of drawings, in which- Figure l is an elevation and partial section of my apparatus. Fig. 2 isa cross-section on line 2 2 of Fig. 1. Fig. 3 is a cross-section through the oi1-supply tube and union, showing the wire-gauze diaphragm located at the junction of thevaporizing-tube with its connecting-tubes.

Throughout the drawings like referenceiigures refer to like parts.

The lamp is preferablymounted on a reservoir or bowl (not shown) containing oil and compressed air, l it being screwed into said bowl by the threaded nipple 1. A valve 2 controls the flow of oil from the bowl through the oil-supply tube 3 to the vaporizing-tube 4, which is preferably made in the shape of a U or horseshoe, so as to extend up alongside of and across the top of the incandescent mantle 20, said incandescent mantle being supported from the vaporiziug-tube by the wire 2l or other convenient means.

23 is a short chimney mounted on the upper portion of the vaporizing-tube, and 22 is a drip-valve in the lower part of the burner apparatus. This burner and air-mixing apparatus is all mounted on or within the upright tube 5. The vapor is carried from the end of the vaporizing-tube by the vapor-dis charge tube 6 into the tube 5 and discharged through the outwardlyflaring opening 7 into the upper end of the mixing-tube 8. This mixing-tube is of less diameter and length lthan the upright tube and is located, preferably, concentric therewith.

Air-conduits 8 8b extend in through the walls of the upright tube 5 and lead to the upper end of the mixing-tube 8. A bell-shaped mufer 9 overhangs the openings to these air-conduits, and on said muffler or on other pivotal bearing supported by the upright tube 5 is pivoted the vibrating arm 10, which carries the needle l0a at its inner end, adapted to enter the discharge-opening 7 for cleaning the same of accumulated material whenever the arm l0 is vibrated by pulling on the chain ll, connected to its outer end.

The spring l0b is mounted on the supporting-frame work and engages the lever 10 by means of the lug l0C thereon or equivalent arrangement and operates to normally hold the said swinging lever in position shown in Figs. land 2, so as to withdraw the needle from the discharge-orifice and also to one side ofthe line of discharge.

12 represents the 'burner proper, which is formed by contracting the upper end. of the main tube 5 or by inserting a thimble therein. The gauze 13 is placed over the burneropening and held in place by the annular cap let. A second lower gauze l5 may be inserted in the burner. A metal collar is placed on the upper end of the tube 5 and surrounds the burner l2, leaving an annular space between the two. This collar,`as shown, is in metallic contact with the tube 5, and the particular construction shown might be varied so long as any construction was employed which gave free conduction of heat from the collar 16 to the body of the tube 5. The metal collar 16, in conjunction with the upper portion of the tube 5 and burner formed thereon, constitutes a convenient annular receptacle 18 for alcohol to'be used in starting the lamp into operation. The U- shaped vaporizing-tube 4 1s connected to the oil-supply tube 3 and the vapor-discharge tube G, which are located on opposite sides of the burner, by means of the unions 17 17a, 9

and between the abutting ends of the tubes I preferably introduce gauze diaphragrns 19, as shown.

y radiated vheat of the flame and mantle and then passes onto the central section 4 of the vaporizing-tube of greater diameter, where it is also subjected to the heat of the hot gases concentrated by the chimney 23. Vapor passing through the vgauze diaphragm 24 passes into 'the mouth 25 of the inwardlyprojecting portion of the part 4b of the vaporizing apparatus and passes down through said part 4b, being further superheated by the radiated heat from the mantle and burner. It is then delivered to the discharge-tube 6 and passes out of the discharge-opening '7 in the form of a jet. This jet passes down the mixing-tube 8, drawingin the necessary quantity of air through the air-conduits SiL 8l. The noise of the jet is partly muffled and suppressed bythe muffler 9. The mixture of air and vapor passing out of the lower end of the mixing-tube 8 strikes the closed lower end of the upright tube 5 and is then compelled to change its direction and pass up through said tube 5 to the burner l2, where it is burned under the mantle 20, giving off heat sufficient to maintain the vaporizing-tube 4 at the necessary temperature. By pulling on the chain 1l the needle l0 can be projected up through the opening 7 when the same has become clogged by the accumulation of carbon, cleanses the opening, and enables the lamp to continue in operation. The spring 10b normally holds the needle-carrying lever in the position shown in the drawings, but yields to a pull on the chain ll sufficiently to permit the operation above described.

The advantages of my invention consist in its simple and compact form and in the fact that the mixing operation is all done within the short tube 5, which is kept hot by the fact of its metallic connection with the burner l2 and the -surrounding collar 16. 'Ifhe lower skirts of the mantle 20 are of course kept hot by conduction from the upper portions, which are in the immediate vicinity of the liame, and heat radiated from this lower skirt of the mantle is intercepted by the metallic collar 16. The oil-supply tube is also carried up through this upright tube 5 and bathed in the current of hot vapor and air within the same. A further advantage is that the oil and vapor delivered to the central section 4 of the vaporizing apparatus accumulates therein quantity on account of the larger diameter of this central section and furnishes a means of producing an even supply to the portion 4b of the vaporizing apparatus and discharge-tube 6. Moreover, the projecting portion 25 of the portion 4b entering the central section 4, as shown, forms a sort of trap in the shape of an annular recess around the part 25, in which any unvaporized oil or solid ,matter will be deposited instead of passing on through section 4b to clog up the dischargeorifice 7. The inlet portion of the vaporizing apparatus projecting into the central section also forms a trap to prevent the backward flow of any deposited impurities to the said inlet-section.

Itis evident, ofcourse, that various changes could be made in the details of construction illustrated without departing from the spirit and scope of my invention so long as the relative arrangement of parts shown in the drawings or the principle of operation set out in the specification is preserved.

The form, construction, and connections of, for example, the Vaporizing tube, the chi mney supported thereby, the upright tube, the burner, the muffler, dto., herein shown and described are not claimed, for the reason that these parts constitute the subject-mattei' of other applications now pending.

Having therefore described my invention, what I claim as new, and desire to protect by Letters Patent, is

In a vapor-burning apparatus the combination of the upright tube adapted to be screwed into the top of an oil-reservoir but closed at its lower end, the burner on the upper end of the upright tube, the miXingtube of less length and diameterthan the upright tube and located within the same, the vaporizingtube locatedwithin the heating zone of the burner and ldischarging into the upper end of the mixingtube, and the air conduits through the walls of the upright tube leading to the upper end of the mixing-tube, together with the needle hole-cleaner pivoted to the upright tube and extending in through the air-conduit, and the spring normally acting to Withdraw the needle out of the line of discharge from the vapor-discharge opening.

Signed by me at New York city, New York, this 26th day of April, 1899.

ARTHUR KITSON.
