GAS-BURNER.

SIECIFICATION forming part of Letters Patent No. 434,013, dated August 1'2, 1890. Application iiled December 14, 1886. Serial No. 221,496. (No model.)

To all whom it may concern.'

Be it known that I, JOHN F. BARKER, of Springfield, in the county of Hampden and State of Massachusetts, haveinvented certain new and useful Improvements in Gas-B urners, of which the following is a full, clear, and exact description, whereby any one skilled in the art can make and use the same.

My invention relates particularly to the class of burners used and adapted to burn gas for heating purposes', and is of the Bunsen type; and my obj ectis to produce a burner to burn air-gas that is of a variable quality, richness, or candle-power.

, My invention consists of a burner having a base, a pillar, a mixing-chamber at the base of the pillar, and the peculiar arrangement of the independent and separately adjustable air and gas valves, and in the combination of such parts with each other, and also with the enlarged jetas more particularly hereinafter described, and pointed out in the claims.

Referring to the drawings, Figure l is a view in central vertical section of my improved burner. Fig. 2 is a view .of the same in crosssection on plane denoted by line a; of Fig. 1. Fig. 3 is a plan view of the burner top or jet.

In the accompanying drawings, the letter a denotes the base of the burner, that is usually of metal cast to shape, with the tubular inlet b and an upright steine, onto which is screwed or otherwise adjustably fastened the lower end of the pillar d. The upper end of the stem c, which is hollow, has a number of openings c lfor the passage of the gas, and between them a tapered or pointed spindle c2, which extends into an opening d in the concave bottom of the pillar when the parts are screwed together. The base of this pillar is enlarged so as to form an air-chamber e, and through the walls of this piece are the port-openings e', while arotary collar or sleeve f surrounds the base and is movable on it, so that the openings through this gate may be made to register with the openings in the airchamber, or the latter may be closed by turning the sleeve a sufficient distance. The main body of the pillar extends above this chamber for a certain distance and terminates in 'that is enlarged to several times the size of the main pillar, and has a number of outlet-openings through the top of the tip and also through the side Walls, the latter being Wit-hin a chamber formed about the sides of the top and opening on about the level of the top of the latter. base of the pillar upon the stem the valvespindle may be made to open or close the valve-opening d', that controls the flow of gas into the mixing-chamber and through the pillar, and when the adjustment .has been made for the desired quantity of gas afurther adjustment of the parts may be made by moving the collar f, so that the' exact quantity of air necessary to produce either a yellow flame or a green iiame may be allowed to enter the chamber e, and mixing with the gas pass through the pillar to the jet, where it may be ignited.

In theordinary form of Bunsen burners the gas-inlet is of a iixed size, as it is adapted to be used with coal-gas that is always o'f cer= tain standard richness of about eighteen candlepower; but such a form of burner is not adapted for use with carbureted air, in which this quality is very variable. By yadjusting the gas-valve to admit the proper quantity of gas in relation to its richness at a given time'A there is danger of so increasing the velocity as to blow the dame off the top of the burner,

,so that with merely this adjustment the burner would be of but little value. By providing means for regulating the supply of air also the desired kind of iiame may be furnishedat the tip of the burner Without its requiring any change in the size of the pillar that would otherwise be necessary to obtain the same result in the absence of an air-controllin g valve.

By the term independent, as applied to the valves in the following claims, I mean to refer to the feature of separate adjustment that enables the quantity of air alone or the quantity of gas alone Ato be controlled 4or determined as it iows into the burner.

I claim as my improvement- 1. In a burner, in combination With a base having an inlet-opening, a projecting stem adjustable vertically in the base and terminating in a pointed valve-spindle, the pillarbase having an inlet-opening for gas located opposite the end of the valve-spindle, the pillar adj ustably mounted on the base and having the enlarged mixing-chamber with ad By turning the n ICO of air, the adjustable gate f,and the burner top or jet sui-mounting the pillar and having a diameter larger than that 0f the pillar and provided with a plural number of outletopenings on the top and sides, all substantially as described.

JOHN F. BARKER.
