GEORG REIMANN, OF BERLN, GERMANY.

BUNSEN BURNER.

SPECIFICATION forming part of Letters Patent No. 478,364, dated July 5, 1892.

Application led August 6, 1890. Serial No. 361,210. (No model.) Patented in England December 24, 1889. No. 20,744; in Germany December 27. 1889, No. 50,448, and in Austria-Hungary October 11, 1890, No. 20,997 and No. 39,558.

To all whom it may concern:

Be 1t known that l, GEORG REIMANN,

. manufacturer, of Berlin, in the Kingdom of Prussia and German Empire, have invented new and useful Improvements in Bunsen Burners, of which the following isV a specification, reference being had therein to the accompanying drawings.

This invention has been patented to me in Great Britain under No. 20,744, of December 24, 1889; in Germany under No. 50,448, of December 27, 1889, and in Austria-Hungary under date October ll, 1890, No. 20,997 and No. 39,558.

This invention has for its object the simplification of Bunsenburners and the simultaneous and corresponding regulation of the admission of gas and air thereto. To this end the tube used in'ordinary Bunsen burners for" the exit of the gas, and which is frequently liable to become fouled and stopped up, is in a burner constructed according to this invention dispensed with and the burner-tube is made to act as a regulating-cock both for gas and air.

A Bunsen burner according to this invention is illustrated in the drawings, in which- Figure I is an elevation of the burner; Fig. Il, a vertical section through the gas-outlet opening. Fig. III shows the lower part of the burner-tube in elevation, the foot-piece or holder therefor and the gas-supply branch being in section, the several parts being shown in the positions they occupy when the gas and air passages are half-opened; and Fig. lV is a plan of the burner.

a is the burner-tube, with lower tapering or conical end b, that forms a plug-cock, through which is an inclined lateral slot or openin g c for gas. This slot or opening communicates by a recess c in the conical end b with a gasinlet passage c in the branch or union e', to which a flexible tube can be attached. This recess c is of tapering form, as shown, so that the cross-sectional-area of the passage for gas from the passage e can be varied by adjusting the position of the recess in relation to such passage c.

d is the lower part of the burner, secured by screws to a foot d. It serves as a holder for the burner-tube and is formed with lateral air-holes h and carries a set-screw g.

The burner-'tube a, which is furnished with handles f for turning it, has its conical lower end fitted in the holder CZ, in which it is retained by screwing in the set-screw g, so as to cause it to enter a slot in the tube Fig. Il. The recess c and slot or opening c can by turning the tube b be either placed in communication with the gas-supply passage c or this communication can be closed, as desired. The arrangement is such that when the tube b is turned so that the narrow part of the recess c is opposite the inlet-passage e and onlyv a small quantity of gas can enter the recess c and slot or opening c, the lugs or parts b', formed by slotting the lower conical end b of the tuberct, will be brought partly in front of the air-inlets h, so as to partly close these airinlets, and by turning the tube b to a further extent to increase the area of the gas-passage in c the lugs or parts b' will further uncover the air-inlets h in such a manner that the airsupply will be regulated in exactly the same proportion as the gas-supply, thereby obviating the veryinconvenient blowing through or back ignition of the flame that is liable to take place with Bunsen bu'rnersofordinary construction when the supply of gas isreduced.

By means ofthe hereinbefore-described construction of Bunsen burners the following advantages are secured:

First. By means of the simultaneous automatic regulation of air in exact proportion to the supply of gas the flame is prevented from becoming white, and consequently from becoming smoky or sooty, and further back ignition of the dame when the latter is turned very low is prevented.

Second. Since there is no special nozzle or mouthpiece for the exit of the gas into the burner-tube, as in ordinary Bunsen burners, there is no liability of the burner becoming stopped up. y Y y Third. Convenience in handling,sincein order to regulate the flame no cock (which is often situated at a distance) has to be adjusted, the regulation being effected by simply rotating the burner-tube in its holder.

Fourth. Economy in gas, since the mixture Ico of `tras and air is more uniform and the resulting` combustion more perfect.

Ido not claim, broadly, a perforated cylindrical portion adapted to turn within an outer perforated shell in order to regulate the supply of fluid; but the essential pointin my construetion consists in utilizing the burner and oonveying-tube as the regulating means, it being joined to the foot-piece so that it may turn, and upon this feature my Claim is based.

What I claim, and desire to secure by Letters Patent of the United States, is-

In a Bunsen burner, the combination of a burner-tube for conveying the iniianimable GEORG REIMANN. Witnesses:
