VAPOR-BURNER.

SPECIFICATION forming part of Letters Patent No. 633,617, dated September 26, 1899.

Application filed May 21, 1898. Serial No. 681,321. (No model.) I

To whom it may concern:

Be it known that I, WILLIAM SCOTT, a citizen of the United States, residing at Kansas City, in the county of Jackson and State of Missouri, have invented a new and useful Vapor-Burner, of which the following is a specification.

This invention relates to that class of illuminatin g apparatus or devices which convert a hydrocarbon into vapor prior to consuming the same at the escaping-orifice.

The purpose of the invention is to secure a soft light of good quality and to economize in the consumption of the oil proportionate to the effective light obtained.

The invention also has for its object to provide for a nicety of adjustment of the parts, so that no waste of vapor is possible and the proper amount of air at a suitable temperature may be intermixed therewith, so as to secure the required combustion essential to the production of a flame of great illuminating power.

For a full understanding of the merits and advantages of the invention reference is to be had to the accompanying drawings and the following description.

The improvement is susceptible of various changes in the form, proportiomand the minor details of construction without departing from the principle or sacrificing any of the advantages thereof, and a full disclosure of the invention and adaptation thereof is shown in the accompanying drawings, in which- Figure 1 is a sectional detail of a lamp or illuminating device constructed in accordance with this invention. Fig. 2 is a detail view of the generator. Fig. 3 is a detail view in perspective of the body portion of the burner, parts being broken away. Fig. 4c is a; detail view of the gallery, the sleeve connected therewith and rotatably mounted upon the body portion of the burner, and the lower portion of the shade-holder. Fig. 5 is a sectional detail of the burner, the upper portion of the chimney-holder being broken away. Fig. 6 is a detail view, partly in section, of the adj ustable vapor-burning pipe.

Corresponding and like parts are referred to in the following description and indicated in the several views of the accompanying drawings by the same reference characters.

The reservoir or fount for containing the oil is represented by the numeral 1 and is shown provided with a stem 2, having an eye at its upper end to receive a hook, pin, or like device from which the lamp is suspended. The fount is provided with an opening in its upper portion which is closed by means of a screw cap or plug 3. A pipe 11 connects with the lower portion of the fount and is provided at its lower end with a T-coupling 5, to which pipes 6 and 7 connect. T-couplings S and 9 are fitted to the lower ends of the pipes 6 and 7 and have other pipes 10 and 11 connected therewith. A T-coupling 12 joins the lower ends of the pipes 10 and 11 and has a burner of any desired pattern, make, or style applied thereto.

A generator is located above the burner and consists of a horizontally-disposed pipe 13, secured at its outer end to the T-coupling 8 and having its inner end made tapering,

as shown at 14, and terminating a little to one side of a line passing vertically through the burner, but in the path of heated air. rising therefrom. A needle-valve 15 is located within the pipe 13, and its inner end is made tapering to close the orifice formed at the extremity of the tapering end 14 of the generator. This valve is slidingly mounted in the pipe 13 and in a stuffing-box l6, fitted to the T-coupling 8, and connects at its outer end with a bow-spring 17, which is made fast at one end of the T-coupling 8 and is movable at its opposite end by means of a setscrew 18. The spring 17 normally exerts an inward pressure against the valve 15, so as to hold its tapering end seated against the inner portion of the tapering end 14 of the generator, thereby cutting off all escape of the oil or vapor. It is obvious that the needlevalve may be operated by any of the means commonly employed in apparatus for burning hydrocarbon after it has been vaporized; but the means herein set forth are preferred, inasmuch as a firm seating of the valve is insured at all times, because it operates by a reciprocating movement which does not tend to grind or wear away the valve and its seat,

and at this point it will be further observed that while the needle-valve 15 is preferably used the same may be substituted by an ordinary stop-cock or cut-off valve arranged at a suitable point in the line of the generator-pipe 13.

The vapor-receiving pipe is adjustable and composed of telescopically-related parts and alines with the pipe 13. The fixed part or section 19 connects with the T-coupling 9, and the adjustable section 20 is slidably mounted upon the section 19, and its outer end is made flaring, as shown at 21, to receive the tapering end portion 14: of the generator and insure a proper deflection of the vapor into the main portion of the pipe or tubular section 20. The joint between the sections 19 and 20 is such as to prevent any escape of vapor and also prevent the movement of the part 20 except upon the application of properly-directed. force thereto. The distance between the delivery end of the generator and the receiving end of the adjustable pipe can be adjusted to a nicety, so as to prevent any escape of vapor and insure it taking up the proper quantity of air to secure the combustion of the vapor at the burner.

The vapor-receiving pipe is located horizontally above the burner, and its receiving end, while located at an interval from the discharge end of the generator-pipe, is arranged in the path of heated air rising from the burner, whereby air which is inducted into the receiving-pipe by the discharge of vaporized fuel into the latter is of such a temperature as not to chill the vaporized fuel, and thus tend to return it to a liquid state. The air which is thus intermixed with the vaporized fuel is approximately of the same temperature as said fuel and is in a rarefied condition, adapting it to mix intimately with the vapor and, in fact, assist in securing such a complete vaporization of the fuel as will increase the efficiency of the combustion of the mixture when it reaches the burner-tip.

The burner is composed of a number of cooperating parts, among which is the body portion, consisting of a tube 22, having a series of slots or openings 23 in its sides, at its lower end, and a thimble 24:, which makes screw-thread connection with the vertical branch of the T-coupling 12 and with the lower end of the tube 22. A plate 25 is located about at the juncture of the tube 22 and thimble 24 and is provided with minute openings for the escape of the vapor. A sleeve 26 is rotatably mounted upon the lower end portion of the tube 22 and is supported with the vapor to secure the requisite degree of combustion. A series of arms 28 are secured to the sleeve 26 and curve upwardly and outwardly, and their upper outer ends are bent, forming rests 29 to receive the lower end of the shade 30. The gallery 31 is secured to the outer end portions of the arms 28 and is formed with a cone 32, which is sup plied at its apex with a ring or band 33, containing a wire or gauze piece 34 to prevent the flame entering the tube 22 when the burner is lighted. A cap 35 is fitted over the ring 33 and is supplied with a wire or gauze piece 36 for a like purpose. to the part 34. The mantle 37 is suspended from a holder 38 in the ordinary manner, saidholder having adjustable connection with the gallery 31 in the usual way. at their lower ends to the outer end portions of the arms 28 and are connected at their upper ends by a ring iOand, with said ring, constitute a holder for the shade.

The pipes '7 and 10 are closed at their ends,

so as not to admit of a passage being had therethrough. \Vhen the lamp is in operation, the hydrocarbon passes from the reservoir or fount 1 through the pipes land 6 into the generator 13 and is vaporized by the heat 5 from the flame, the vapor passing into the extensible pipe 19 20 and thence to the burner through the pipe 11, where it is consumed. In order to start the lamp, it is essential that the generator be heated, so as to cause a volatilization of the hydrocarbon, and this may be efiected in a variety of ways; but it is preferred to have recourse to a spirit-lamp 41, which is suspended from either the generator or the extensible pipe. provided with a hooked plate 42 and a spout 43, the latter being filled with wicking or any absorbent material. The body of the lamp is of box form and is filled with Wicking or any absorbent material, so as to obviate dan- 11o the flame and said fount and is suspended from the T-coupling 5.

While the invention is shown applied to a suspension-lamp, it is to be understood that lamps of the bracket variety or of any style or pattern may have the invention applied thereto, the vital feature being the generator and extensible vapor-receiving pipe located above the flame and having connection with the fount and burner, respectively,

whereby the hydrocarbon is supplied to the generator and is vaporized by the heat of the flame, and the latter is supplied by the hydrocarbon in the volatilized state to the burner.

Having thus described the invention, what Vertical rods 39 are secured 85 This spirit-lamp is 105 is claimed as new, and desired to be secured by Letters Patent, is
