GMT 44o/wao RUDOLPH E. BRUCKNER, OF MOUNT VERNON, NEW YORK.
INVERTED MANTLE-BURNER.
Specification of Letters Patent.
Patented Dec. 27, 1910.
Application filed May 28, 1910. Serial No. 563,888.
To all whom it may concern:
Be it known that I, RUDOLPH E. BRUCK- NER, a citizen of the United States, residing at Mount Vernon, county of lVestchester, State of New York, have invented certain new and useful Improvements in- Inverted lVIantle-Burners, of which the following is a full, clear, and exact description.
My invention relates to .improvements in inverted mantle lamp construction adapted to burn acetylene and other gases high in carbon.
The invention consists in certain improvements in the burner itself whereby gases high in carbon may be successfully employed in lamps of this character and without danger of sooting up the mantle.
In the drawings-Figure l is in the main a sectional view showing a car lamp with my improved inverted burner in place therein; Fig. 2 is a detail view relatively enlarged; Fig. 3 is another detail view relatively enlarged.
l represents the gas supply tip having a small orifice through which the gas is etted.
2 is a mixer tube having a passage therethrough, which, relatively to the size of the orifice in the tip l, is much larger.
3 3 are the main air admission ports at the base of the tube 2 and closely adjacent to the tip l. The flow of gas through the tip l and into the relatively large bore of the tube 2 draws in, by the injector principle, air through the ports 3 3, which becomes mixed with the gas in and at the entrance to the bore of the tube 2. rEhe bore of the tube 2 is provided with an hour-glass contraction.
4 4 are supplemental air inlet ducts between the main ports 3 and the burner end, each of said ports being of suliicient length to give-direction to the flow of air therethrough, and arranged obliquely and in such a direction that the flow of mixed air and gas through the tube 2 will not be diverted out through ducts 4 4 but on the contrary will vinduce an inward flow of air through said ducts, to build up in oxygen the previously formed mixture, by which I find the combustion of the gas at the mantle end of the burner is very materially improved.
5 represents the mantle ordinarily employed and which may be secured to the downwardly directed burner outlet end 6. The supplemental air ducts 4 4 communicate with the bore of the tube 2 at a point closely adjacent to ,its most contracted part whereby an effective injector action is secured at this point through ducts 4- 4.
The orifice in the tip or nozzle l preferably directs the gas centrally into the bore of the mixing tube.
It will be observed that in the form shown and in the preferred form, the secondary air inlet ducts 4- 4 are symmetrically arranged or uniformly spaced, whereby the air entering the bore of tube 2 will be better balanced and distributed.
What I claim is:
l. In a burner of the incandescent mantle type, a gas supply tip, a mixing tube having an our-glass passage therethrough, a main air inlet at the base of said tube, said tube having asupplemental air duct of suiicient length to give direction to the flow of air therethrough, said duct communicating with said hour-glass passage approximately at its smallest diameter and inclined relatively to the axis of said passage, and a downwardly extending outlet at the end of said mixing tube.
2. In a burner of the incandescent mantle type, a gas supply tip, a mixing tube having an hour-glass passage therethrough, a main air inlet atthe base of said tube, said tube having supplemental air ducts of sufficient length to give direction to the flow of air therethrough, said ducts communicating with said hour-glass passage approximately at its smallest diameter, and inclined relatively to the axis of said passage, and a downwardly extending outlet at the end of said mixing tube.
