AUTOMATIC GAS-BURN ER.

SPECIFICATION forming part of Letters Patent No. 732,068, dated J' une 30, 1903.

Application filed February 27, 1902. Serial No. 95,972. (No model.)

T0 all 1071.017@ t may concern:

Be it known that I, CYRUs A. HAAs, a citizen of the United States, residing at St. Louis, State of Missouri, have invented certain new and useful Improvements in Automatic Gas- Burners, of which the following is a specilication.

The invention relates particularly to automatic gas-burners constructed and arranged to be used in connection with Welsbach man' tles, and particularly to the construction and arrangement therein of au automatic pressure-regulating device, all of which will more fully hereinafter appear.

The principal object of this invention is to provide a gas-burner for Welsbach inantles with an automatic pressure-regulator therein by which the flow of gas therethrough is automatically regulated according to and by the pressure therein. Y

Further objects of the invention will appear from an examination of the drawings and the following description andclaims.

The invention consists principally in an automatic gas-burner in which there is coinbined a casing provided with a plurality of perforations extending therethrough and a regulating device for closing said perforations independently or simultaneously according to the pressure of gas therein.

The invention consists, further, in an automatic gas-burner in which there is combined a casing provided with a plurality of closing devices arranged adjacent to the perforations to close the same independently or simultaneously.

The invention consists, further, in an automatic gas-burner in which there is combined a casing provided with a plurality of perforations in the end thereof and a spider-shaped regulator provided with a plurality of closing devices attached thereto and adjacent to such perforations to automatically close a plurality of the same.

The invention consists, further and finally, in the features, combinations, and details of construction hereinafter described and claimed.

In the accompanying drawings, Figure lis an elevation of a Velsbach burner constructed in accordance with these improvements; Fig. 2, an enlarged sectional elevation of a portion of the same; Fig. 3, a plan View of the toppart of the burner shown in Fig. 2, illustrating the regulator in dotted outline; Fig. 4., a cross-sectional plan view taken on line 4 of Fig. 2 looking in the direction of the arrow, and Fig. 5 a perspective view of the spider-shaped regulator removed from the burner.

In the art to which this invention relates it is well known that the flow of gas through a burner is dependent upon the pressure behind the same and that'during dierent times of the day and owing to different circumstances and conditions, of which no mention need be made here, the pressure in the mains and in the servicepipes varies, and as a consequence the iiow of gas through the burner varies proportionately. This is a Well-known objection in the use of Welsbach mantles, as a flickering takes place which is not only ol)- jectionable to the user and hard on the eyes, but results sometimes in impairing the elficiency of the Welsbach mantle or the destruction thereof.

The principal object, therefore, of this invention is to provide an automatic gasburner of the kind alluded to in which the pressureis-taken advantage of to control or regulate the flow of gase-that is, to open or close, as necessity demands, one or more of a plurality of minute perforations, as will more fully hereinafter appear.

In constructing a burner in accordance with these improvements I provide a cupshaped casing d, which is internally screwthreaded to fit a service-pipe b, mounted in any convenient location, either upon a wallbracket or in va stand-lamp, as may seem desirable or necessary. Secured to this casing in any Way is the upper portion of the chimney-bracket and mantle-supporter c.' (Shown in dotted lines in Fig. l.)

To secure the desired How of gas through the burner-casing a, the upper end wall d is provided with a plurality of

perforations

1, 2, 3, 4, 5, 6, 7, and 8 of varying sizes, hole No. 1 being the largest, No. 2 the next largest, and so on down to the smallest, 6, 7, and 8, so that the gas may pass through one or more of them whenever they are unobstructed. In order to regulate the flow of gas through the same in an automatic manner, I provide IOO an automatic pressure spider-shaped regulator e, composed of a central hub portion which is riveted at f to the central portion` thousand in thickness and which is very yielding and elastic, so that the least amount of pressure will cause the same to operate. As shown in Figs. 2 and 5 of the drawings, the valves are bent downwardly and away from the same plane which the hub occupies, so that when in their normal position the perforations extending through the end of the burner-casing are unobstructed and at normal pressure the gas may ow therethrough. When the pressure is excessive, however, the tendency of the gas will be to flow through the larger openings and operate the disks to move them against theilI respective openings one after the other in the order of their size, the largest first, and so on until the desired How of gas is obtained. When the-pressure decreases, they open inversely, those which close first opening the last, and so on until the gas llows in an unobstructed manner through all of the openings. Should a sudden pressure develop, all of the valved openings will be closed simultaneously with the exception of openings 7 and 8, which are always free and in position to permit gas to flow therethrough, thus insuring a substantially uniform ow of gas, which will be understood and appreciated by those skilled in the art.

I claiml. In an automatic gas-burner, the combination of a casing provided with a plurality ot' perforations, and a plurality oi closing devices arranged adjacent to the perforations to close the sameindependently and successively, substantially as described.

2. In an automatic gas-burner, the combination of a casing provided with a pluralityv for a plurality of such openings to open and close the same automatically, substantially as described.

4. In an automatic gas-burner, the combination of a burner-casing provided with a plurality of openings in the end wall thereof, and a regulator provided with a plurality of independently and automatically movable valves for automatically opening and closing a plurality of such perforations, substantially as described. Y

5. In an automatic gas-burner, the combination of a burner-casing provided with a plurality of perforations in the end wall thereof, a yielding spider-shaped regulator secured thereto provided with a plurality of valves for opening and closing a plurality of such perforations by the pressure of gas therein, substantially as described. l

6. In an automatic gas-burner, the combination of a burner-casing provided with a plurality of perforations extending` through the end VWall thereof, and a metallic spidershaped regulator secured thereto and provided with a plurality of valves for opening and closing-a plurality of such perforations by the pressure of gas therein, substantially as described.

7. In an automatic gas-burner, the combination of a burner-casing provided with a plurality of perforations extending through the end Wall thereof, and a yielding metallic spider-shaped regulator provided with a plurality of disk-shaped valves extending radially from a central point for opening and closing a plurality of such perforations by the pressure of gas therein, substantially as described.

8. In an automatic gas-burner, the combination of `a burner-casing provided with a plurality of perforations of various diameters, and a yielding metallic spider-shaped regulater having a plurality of disk-shaped valves for opening and closing a plurality of such perforations by the pressure of gas therein, substantially as described.

9. In an automatic gas-burner, the combination of a casing portion provided with a plurality of perforations extending therethrough, and automatic valve mechanism arranged therein comprising a .plurality of integral independently-movable flexibly-connected valve portions for automatically opening and closing a plurality of such perforations, substantially as described.
