Specification of Letters Patent.
Patented Aug. 1, 1911.
Application filed August 22, 1910. Serial No. 578,4.44.
To all whom it may concern:
Be it known that I, MANUEL ANTONIO GALVAO, a citizen of the United States of Brazil, and resident of Paris, France, have invented certain new and useful Improvements in Vapor-Burners, of which the following is a specification.
This invention relates to improvements in the construction disclosed in my prior Patent No. 953,906, dated April 5, 1910, and particularly to the means for distributing the gaseous mixture to the burners proper.
The object of the invention is to provide a construction for more readily and expeditiously burning a larger volume of the gaseous mixture to increase the flame, whereby the device is adapted for various uses.
The invention also relates to the specific details of construction and arrangement of parts which will be hereinafter described and particularly pointed out in the clalms.
In the accompanying drawings: Figure 1 is an elevation, partly in section, and illustrating the use of the invention when several mantles are employed. Fig. 2 is a top plan view of the burner. Fig. 3 is a horizontal valve section through the vaporizing and mixing chamber, the vaporizer being in plan view. Fig. 1 is an elevation partly in section of a modified form of the invention. Fig. 5 is a detail plan view of the burner shown in Fig. 4:. Fig. 6 is a detail plan View of a different form of burner. Fig. 7 is a perspective view of a range with my invention applied thereto. Fig. 8 is an elevation of a heating stove, with the inven tion applied thereto.
The letter A, indicates a chamber formed with a central opening J, and adjacent thereto other openings J, and over the. latter are screens J Below the opening J, is formed a cup Gr, to receive liquid fuel to prime the burner. Surrounding the chamber A, is an annular chamber A, having a downwardly and outwardly inclined bottom A and formed in its top with a series of opening A provided with screens C. The chambers A and A are separated by a slight space, indicated at I, and are con nected by pipes B, B.
Located above and spaced from the open-- ing J, and spaced from the chamber A, is a vaporizer 9, comprising a chamber formed in its top and bottom with openings, for the reception of tubes 19, for the passage of the heat when priming the burner. A tube 6, extends from'the vaporizer, and within this tube is a bushing 8. This receives the stem 11, of a needle valve 1 1, the latter operating in a tapered opening 10, in the chamber of the vaporizer. A supply pipe 2 communicates with the tube 6, and bushing 8, to supply liquid fuel to the vaporizer.
In alinement with the tube 6, and extending from the opposite side of the vaporizing chamber is a tube 9*, which is reduced at its outer end 15, the latter communicating with a mixing chamber. The mixing chamber comprises a horizotnal tube 21, disposed at right angles to the tube 9 and open at both ends for the admission of air. Extending from the tube 21, and in alinement with the tube 9, is a pipe 22, which is curved at its end A, and communicates with a pipe 23, leading to the annular chamber A.
Mantles, one of which is indicated at D, are supported over the screened openings A so that a series of heat radiating surfaces are provided. Each mantle is provided with a rod E, supported on the rojection F. lVhen operating this form of t e invention, liquid fuel is introduced in the cup G, which when ignited heats, the vaporizing chamber, and the chamber A, the flame passing up through the opening J, and the tubes 19, and in the passage thereof, a sufficient quantity of air is mixed therewith to readily promote combustion. The valve 14 is opened, and as the liquid fuel introduced in the vaporizer becomes heated it is injected through the restricted exit opening 15, of the tube 9 As the vapor. is formed it is blown into the tube 22, and creates a partial vacuum in the tube 21, and thereby air is sucked into said tube to mix with the vapor. The mixture is directed by the pipes 22 and 23, into the annular chamber A, from whence it is distributed to the screened openings C, and through the pipes B, to the screened openings J The vapor may be ignited at the screened openings, or the mantles, as the case may be. Projecting from the needle valve 141, is a rod 13, which extends through the vaporizer and the restricted opening 15, of the tube 9. When the valve is moved back and forth during the operation of the burner, the rod 13, is reciprocated through the opening 15, which serves to keep the passage clean.
For producing a large flame, I may substitute a burner such as shown in Figs. 4: and
which are inclined, the outer chamber being of annular formation, tubes connecting the chambers, and a pipe communicating wlth the annular chamber opposite the inclined 5. This burner comprises a chamber K, having a central depression L, and an annular screened opening N, between the depression and the outer wall of the chamber.
Extending from the depression L, to the bottom and the vaporizer. casing K are inclined air inlet pipes M, and 2. In a burner, the combination of achamcommunicating with the bottom of the her formed with a plurality of screened chamber is a pipe 23. The pipe 23, extends openings and having an inclined bottom, an upwardly to a point above the plane of the annular chamber surrounding the aforesaid top of a mantle O, fitted over the burner. chamber and spaced therefrom and provided The pipe comnnmicates with a vaporizer 20 with an inclined bottom, said annular chamlocated over the mantle, as clearly shown in her having aplu ality of screened openings, Fig. 4. pipes connecting the two chambers, a vaporln lieu of the arrangement of mantles izer, and a tube communicating with the shown in F l and 2, I may make the vaporizer and the annular chamber. openings in the chamber A larger, as shown A burner of the class described, comin Fig. 6, to obtain a greater heating area. prising a chamber having an inclined bothen using the improved burner for a tom and provided on top with a screen, range, the fuel tank R, is mounted on a pipe means for admitting air inside the plane of T, as shown in Fig. 7. the screen, a vaporizer over the burner, a
pipe connnunicating with the Vaporizer and the burner, and a valve for controlling the vaporizer.
In testimony whereof I have hereunto set my hand in presence of two witnesses.
For heating stoves the burners are placed in the bottom, and the reservoir R and sup ply pipe extend to the outside, as shown in Fig. 8.
What I claim is:
1. In a vapor burner, the combination of a vaporizer, a valve for controlling said vaporizer, a burner arranged under the vaporizer, said burner comprising a plurality of separated chambers, the bottoms of Copies of this patent may be obtained for five cents each, by addressing the Commissioner of Patents.
