VAPOR-LBURNER.

SPECIFICATION forming part of Letters Patent No. 778,402, dated December 27, 1904.

Application 111611 January 29,1904. Serial N0.191,175..

To all whom it may concern:

Be it known that I, DAVID J. OANcHEsTnR, a citizen of the United States, residing in the city of Chicago, county of Cook, and Stateof Illinois, have invented a new and useful Improvement in Vapor-Burners, of which the following is a specification.

My invention relates to vapor-burners adapted for lighting or heating; and the objects of the invention are to produce an apparatus of mproved construction and arrangement, as will more specifically be pointed out in the following description and accompanying claims. .1

I obtain my objects by the mechanism illustrated in the accompanying drawings, in

.tion of the rack-casing m.

Figs. 11 to 15, both inclu-v stack 0, suspended by any suitable means such, for example, as the arms cl, adapted to be suspended from a rod 0. In the present construction the burner parts are suspended from said rod 0 by means of the frame-rods f, which carry at their lower extremity the frame-tubes g. Said frame-tubes g are hollow, and for convenience the operating-chains it pass down- 'wardly through them from the controlling-lever t'. This arrangement serves both to conceal the greater portion of the chains, and also by protecting them lessens the danger of accidental movement of the controlling-lever i. Said controlling-lever is fastened by means of a setscrew. or other device to the spindle 7', which controls the rack by means of the pinion j. By preference thev body portion of said rack In is cylindrical and fits Within the upper por- Said rack-casing terminates at its lower extremity in the collar m, which is interiorly threaded to receive the valvecasing 02. The upper cylindrical portion of rack-casing m is joined to said collar portion 172/ by means ofthearms m which are integral With both of said parts in and m. This arrangement forms. an open constructionboth for the purpose of reducing the amount of heat that will be conducted upward from the valve-casing to the upper operating parts and for afiording access to the packingnut n, which forms a stuffing-box at the upper extremity of said valve-casing a, through which the valve 0 works. Said valve-casing n is provided With a tapered portion M, which forms a seat for the correspondingly-tapered lower extremity of valve 0, whereby the-flow of oil entering through the supply-aperture n in said casing a may be shut off from the generator below. The. passage a is. formed in the valve-casing a, below the valve-seat n for conducting the oil downwardly toward the generator.

The generator consists of a casing 12, which screws onto the enlarged lower extremity or plug a of the valve-casing n and receives .the

separator Q, which is shown separately in Fig. 18 and also shown in section on larger scale in Fig. 10.

The separator q is provided with verticallyarranged fins or ribs g, which fit tightly enough within the generator-casing to scrape the inside walls thereof when said separator is rotated. At the bottom of the separator a ring or collar g is formed, which also fits within said generator-casing tightly enough to scrape the walls thereof when the separator is lifted out of the casing. Said separator is adapted to rest upon the bottom of the generator-casing formed by the annular shoulder 19 thereof, and said ring g constitutes a false bottom to said generator whereon impurities may be precipitated, so that such impurities may be removed from the generator by lifting out the separator. In order that oil may flow through the separator, however, one or more apertures connect with the interior chamber q. Said vertical ribs q not only act as scrapers, but serve to divide the downwardly flow of oil into a number of streams, so that the oil may be more thoroughly distributed over the surface of the generator and vaporization more completely effected. The purifying-tube 9 screws into the upper opening of the extension-tube s and extends up into said generator-casing p.

In operation the oil passes from the discharge-passage a downwardly through the passages formed between the ribs (1 of the separator, thence through the small apertures Q3 into the interior chamber (1, thence upwardly over the top of the purifying-tube r, thence downwardly through the passage 8', formed in the generator extension-tube s. As the result of this construction the oil as it passes on the outside of the separators begins to volatilize and the greater part of the impurities are formed at this point and dropped on to the ring q. These impurities also appear on the inner walls of the generator and are removed by first rotating the separator to loosen said impurities by means of said ribs q, and, second, by lifting said separator out of said generator, the ring 9 also scraping the generator-walls as it is lifted out. In order that the entire inner surface of the generator 19 may be scraped, one of the ribs 1 extends downward completely to the bottom ring (1 but the remaining ones of said ribs terminate at a point slightly above said ring to thereby form points of engagement for the fingers t of the separator-key t and also to form passages whereby the oil may pass around the bottom of the separator. The body of said key is in the form of a hollow cylinder having slots 25 therein for non-interference with the ribs (1' of the separator q. The outside diameter of the cylindrical portion of the key If is preferably somewhat smaller than the inside diameter of the generator p in order that the key may freely onter said generator to remove the separator, even though the walls of the generator have a considerable coating of precipitated carbon or other impurities.

A disk-like spreader '11 its over the top of the separator 12 to conduct the oil directly to the walls of the generator 7) for the purpose of effecting quick generation. A helical spring 1), located in the recessed lower extremity of the generator plug 91., serves to hold the spreader a and separator 72 down in position within the generator. The needle-stem w screws into the lower extremity of the valve 0 and extends downwardly through the passages a" and .s" and purifying-tube r. Said stem its closely within the apertured top of the separator j], and in order to prevent the oil from passing through the top of the separator alongside of the stem 10 a raised neck (1 is formed at the top of said separator. Said neck also serves as a guide for said needle-stem w. The lower extremity of the stem to is interiorly threaded to receive the holder m of the needle-wire The said needle-holder is centrally bored to receive said wire, and the upper extremity of the wire is bent over, so that when the parts are assembled the needle-wire is held tightly in place with the lower extremity projecting somewhat below the lower extremity of the holder :r, so as to penetrate the aperture formed at the bottom of the needle-valve seat and keep said aperture clean by reason of its up-and-down movement coincident with the movement of the valve (I. Said needle-valve seat screws into the interiorly-threaded lower extremity of the generator extension-tube s. For the purpose of guiding the lower extremity of the needle-stem w a guide 1 is placed near the lower extremity of said generator extension-tube a. Said guide is preferably triangular in cross-section to thereby afford a passage-way for the vapor. The vapor-jet nozzles, which is provided with a vaporjet orilice, is hexagonal in cross-section, so that the same may be readily unscrewed and the vapor may readily escape and pass down ward. in case there is any leakage between said valveseat and the generator extension-tube .v. Said nozzle fits within the aperture 2 of the plug 8, screwed into the upper extremity of the mixing-chamber An alcohol-cup 5 is provided at said plug 3 for preheating the generator. Said 111ixing-chamber screws into the interiorly-threaded boss 6, formed at the point of union of the main burner-tubes 7 7. Said burner-tubes lead away from said point of union to burners such, for example, as the burners 8 8. The inverted air-tubes J 9 connect with the upper extremity of the. mixingchamber 4 through the apertures 10 therein. The lower extremity of said tubes are open and are located at a point below said apertures 10. The purpose of said tubes is to supply air to said mixing-chamber at the point where the vapor first enters into the latter.

As a result of this construction onlyso much air is drawn into the mixing-chamber as is necessary to maintain atmospheric pressure therein and complete combustion, and, moreover, opportunity is afforded for heating the air before entrance into the mixing-chamber, as will be hereinafter more fully described.

. The burner-valve 11 is located within the burner-tubes 7 7 just below the mixing-chamber 4 and is provided with two apertures 12 and 13 of unequal width adapted to communicate with tubes 7 7 and also with the opening 14, which leads to the pilot-burner tube 15. Said burner-valve is rotated bymeans of the knob 16, which controls the plug 17, of Which said valve is a part, and the parts are so arranged that by rotating said valve any one of, the following conditions may be obtained, to wit: First, both tubes 7 7 may be open with the passage 14 closed; second, either one of said tubes 7 7 may be open while the other one is. closed and passage 14 is open, and, third, both of the tubes 7 7. may be closed while the passage 14 is open. These various conditions are illustrated in Figs. 11 to 15, inelusive. The construction of the parts also permits one of thetubes 7 7 to be partly shut off while the other one remains completely open. This last condition is illustrated in Fig. 12. 7

One of the advantages of this construction is that the burners are not all shut off simultaneously; but one is turned on before the other is closed, thereby enabling one of the-burnertubes to be lighted from the flame of another before the latter is turned completely off.

The plug 17 is held in position within the boss 18 at the bottom of the burner-tubes by means of the pin 19' running in the slot 20 in said boss, as best shown in Fig. Said tube 15 is provided with. a pilot-burner 21, the opening whereof is located adjacent to the bottom of the generator 19, as shown, for example, in Fig. 8. The main purpose of said burner is to keep the generator 19 hot during the time when the burners 8 8 are not in use. This will hold the device in readiness to generate vapor without waitingfor preheating by means of alcohol. A secondary purpose of the pilot-burner is to furnish means for lighting the vapor when the burners 8 8 are turned on. In order that the heat from the pilot burner may be retained in contact with the generator 19 and also to protect the upper parts of the device, a hood p is mounted near the upper extremity of said generator.

The knob 16, above referred to, is held in close contact with the lower extremity of plug 17 by means of a screw 22, provided with a head 23. The vertical apertures or bores in the knob 16 and part 17 are of a diameter larger than the diameter of the shank of the screw 22, and this afi'ords a cylindrical space or passage surrounding said screw shank through which the oil may drain when the Said screw-shank is only partially withdrawn from plug 17. The upper extremity of said screw screws into said plug 17 at the bottom said tubes 9 slightly above the lower open extremitythereof. The vapor is supplied to said auxiliary heater through the tubes 25 25 from the burner-valve 11. The top of said auxiliary heater is provided with a flamespr'eading gauze 26. (Shown in plan in Figs. 7 and 9.)

In order to assist in mixing air with the vapor entering the mixing-chamber, said mixing-chamber is somewhat small compared to the combined cross-sectional area of the main burner tubes, pilot burner, and auxiliary burner, and I have found by experiment that the combustion is assisted and the flame rendered more steady by providing a large storage-chamber at the outlet of the'mixingchamber. For this reason I make the bu rner-valve 11 of large capacity, and this has another ad- 'vantagenamely, that the tubes 25 are enabled to rise straight and directfrom within said valve, which is cylindrical and open at the top. In the best, construction the casing for said valve 11 is formed by the metal surrounding the lower openings ofthe burnertubes 7 7 and pilot-burner opening 14. I do not desire tolimit myself to the precise construction or arrangement of the parts here shown, as considerable modification may be made'without departing from the spirit of my invention. It is within my contemplation that this invention. may beemployed for its heating as well as its lighting properties. What I claim as new, and desire to secure by Letters Patent, is
