BURNER.

SPECIFICATION forming part of Letters Patent No. 613,921, dated November 8, 1898. Application filed August 22,1898. fierial No. 689,222. (No model.)

To all whom it may concern: 1

Be it known that I, HABRY M. HAMRIO K,a citizen of the United States, residing in the city and county of'Philadelphia, State of Pennsylvania, haveinvented a new and useful Improvement in Burners, which improvement is fully set forth in the following specification and accompanying drawings.

My invention consists in an improvement in burners in which I employ a tube having a substantially continuous series of openings in the periphery thereof for the exit of flame, said tube having a generator surrounding said openings, whereby flame is caused to impinge on substantially every portion of the adjacent surface of said generator, whereby the hydrocarbon is converted into vapor or gas and the same conducted to a chamber and thence into the burner-tube, said generator being located in proximity to openings through which flames have their exit, Whereby substantiallyevery portion of said generator is heated to a high degree.

It further consists of novel details of construction, all as will be hereinafter set forth.

Figure 1 represents an elevation of aburner embodying my invention. Fig. 2 represents a vertical sectional view on line as 09,,Fig. l. V

Fig. 3 represents an elevationof a cap employed, showing perforations therein. Fig. 4 represents a vertical sectional view of a portion of the tube employed without the use of the cap.

Similar letters of reference indicate corresponding parts in the figures.

Referring to the drawings, A designates the burner, the same consisting of a tube B, having in the present instance the flaring end 0 and having the bars D, which are suitably secured to said tube and to the casing or plug E, which latter is screw-threaded in order to be secured to the place of support and is provided with a chamber F, having the outlet or passage G leading therefrom. H designates a cap which is adapted to be placed on the upper end of said tube B, between which and said cap are situated the screens or gauzes J, said cap having slots K above said screens and being provided at or near its mouth with a screen or gauze L, said screens being held in position by any suitable means.

generator-tube N, which is adjacent to said tube and passes up the same and has a lateralportion N which serves as a generator proper and passes around the cap H at about a level with the slots K, through which the flame is adapted to pass and heat said generator, which serves toconduct the heat to the plug E, since said generator is extended down said tube and communicates with the chamber F in the plug E.

Y designates a screen-which is placed around the cap and covers the perforations or slots, so that the flame which issues therethrough may be steadied.

A suitable pin-valve Q or analogous device is conveniently situated in order to control the supply of hydrocarbon, as desired.

In lieu of the slots L in the cap H, I may employ the perforations R, the efiect being the same, and'I may dispense with said cap H and seat the screens J directly within the tube B, (seen in Fig. 4,) in which eventI will provide perforations S in the tube B, above said screens, andabove said perforations will be placed the gauze or screen L, the effect being the same.

V designates a mantle which is supported above the burner by the rod or bar W, which is removably supported in a lug A by a setscrew B.

The operation is as follows: The hydrocarbon passes through the tube M into the generator-tube N, the amount being adjusted by the valve Q, and passes up to the generator N and around the same, where, the burner having been lighted, flames will play against the generator and the hydrocarbon will be converted into vapor or gas and passes down fromthe generator into the chamber F, from which it is forced through the outlet G and into the tube B, where it mingles with the air and passes through the screens and is ignited.

The screen L serves to cushion enough of the flame to be thrown through the openings in the cap.

readily had and the same replaced if worn or broken, and this is the preferred form; but, as above stated, the screens may be placed directly in the tube and the cap dispensed with.

By employment of the screens L and J in conjunction with the openings surrounded by the gauze Y it will be apparent that no pulsations will occur and the flame will burn evenly and steadily under all conditions.

It will of course be evident that various changes may be made in the construction without departing from the spirit of my invention, and I do not therefore desire to be limited in every instance to the form as herein shown and described.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a burner the combination of a tube having a substantially continuous series of openings therein through which flame is adapted to pass and a generator surrounding said tube and located in proximity to said openings whereby flames are caused to impinge on substantially every portion of the adjacent surface of said generator.

2. In a burner, a tube having a substantially continuous series of openings therein, a generator surrounding said tube, and located in proximity to said openings and means for forcing a flame against said generator,

said openings permitting said fiame to impinge on substantially every portion of the adjacent surface of said generator.

3. In a burner, a tube having openings therein, a screen covering said openings, a generator adjacent said openings and means for forcing flames against said generator, said screen being located intermediate said generator and openings.

4. In a burner, a tube having a substantially continuous series of perforations or openings in the periphery thereof, a generator surrounding said tube, and located in proximity to said openings, a chamber communicating with said generator and a screen above said openings whereby a flame is projected against substantially every portion of the adjacent surface of said generator.

5. In a burner, a tube, a cap therefor having openings therein, a screen above said openings, a screen below said openings, a generator surrounding said openings,and a chamber with an outlet in communication with said generator.

6. In a burner, a tube, a chamber with an outlet below said tube, a cap for said tube having openings in the side, screens above and below said openings, a generator passing upward and around said cap in proximity to said openings and down and communicating with said chamber and means for regulating the supply of hydrocarbon.

7. In a burner, a tube, a chamber for the reception of the hydrocarbon, a substantially continuous series of openings in said tube through which flame is adapted to pass, a generator surrounding said tube and located in proximity to said openings whereby flame is caused to impinge upon substantially every portion of said generator and a pipe leading from said generator to said chamber.

8. In a burner, the combination of a tube having a substantially continuous series of openings therein, through which the flame is adapted to pass, a generator surrounding said tube and located in proximity to said openings, said flame impinging upon substantially every portion of the adjacent surface of said generator and a mantle supported above said tube.

9. In a burner the combination of a tube having openings therein through which flame is adapted to pass a generator surrounding said openings, and a gauze or screen interposed between said openings and generator.

10. In a burner, the combination of a tube having openings therein through which flame is adapted to pass, a generator surrounding said openings, a gauze or screen interposed between said generator and openings, and a gauze or screen located in said tube above and below said openings.

11. In a burner, a tube, a cap supported thereupon, a screen or screens interposed between said cap and tube, a screen supported upon the top of said cap, openings in the latter intermediate said screens, a generator surrounding said openings, a chamber for the reception of the hydrocarbon, and a heat-conducting pipe leading from said generator to said chamber.

12. In a burner, the combination of a tube having openings therein through which flame is adapted to pass, a generator surrounding said openings, and a gauze or screen interposed between said openings and generator, in combination with a mantle supported above said tube.

13. In a burner, a tube having openings in the upper portion thereof, a gauze located in said tube above and below said openings, a gauze or screen located externally of said tube and surrounding said openings, a generator surrounding said last-mentioned gauze and openings, a pipe leading upwardly along said tube to said generator, a chamber for the re ception of the hydrocarbon and a pipe of conducting material leading downwardly from said generator to said chamber.

14:.
