To all whom it may concern: my invention; Fig. 2 is a side elevation, but taken at Be it known that I, ALCORN R nc'ron, of the city, right angles to the view shown at Fig, 1; Fig. 3 is an 55 county, and State of New York, have invented a new enlarged vertical section of the burner; Fig. 4 is a cross and Improved Bunsen Burner, of which the following section on the line 14 of Fig. 3; and Fig. 5 is a cross 5 is a lull, clear, and exact description. section on the line 55 of Fig. 3.

My invention relates to improvements in Bunsen The burner has the usual base or nipple portion burners, and especially that sort of burner which is which is adapted to screw to the service gas pipe, and it adapted to be used to heat the mantle of an incandeshas a reduced upper end 11 and also gas openings 12 I cent gas lamp, although it can be used in any place grouped around the needle valve 13 which extends 10 where it is required to get intense heat out of a mixture upward about the top of the nipple and which is preferof gas and air. ably integral therewith. The nipple or base has the The di'fliculty with most Bunsen burners is that they usual large bore so that an adequate supply of gas can are hard to regulate, and it requires considerable adalways reach the outlets l2. justnlent to get the proper quantity of gas with relation The needle valve 13 is adapted to enter the hole 15 to the influx of air. 14 in the cap 15 which is internally screw threaded Another difficulty is that it is hard to get all the air so as to [it the threaded part ll of the nipple l0, and for that is required at the desired point, and it it were posconvenience the cap 15 has a milled llange 1.6 by which sible to support the chimney portion of the Bunsen it can be turned, and the base or nipple it) has also a tube at the right distance above the needle valve or milled flange. 17 for the same reason.
