-GAS-BIURVNER. f

Be it known'that I, -WILLiAM P. ,WIEMANN,

, a resident of Allegheny, in the county of Allegheny-and State of Pennsylvania, have in-" vented acnew and useful Improvement in following to bea full, clear, and exact dc- Gas- Burners; and :I do hereby declare the scription thereof. I

My invent on relates to gas-burners," and has speclal reference to gas-burners for use 1n connection withboilers, furnaces, kilns,'&c".;

and the 'object of the invention is to; rovide. a cheap,- simple, effective,-and reliab eform of such burner.

In the accompanying drawings, Figure 1 a longitudinal central section' of the burner,

and Fig. 2 is anenlarged cross-sectionof' the same on the line II IIof. Fig.1. Y

As illustrated in thedrawings,1' is a casing for forming amixing-chamber. 2 whichv is from the outer; casin 1 "by a connection 18', which" is provided "with a a tion 9 extending into'the gas-chamber 5' and having a close 9, and extending through an opening in this ortion g, which ro passes 1 at the outer end with an adjusting-wheel15.

This valve 13 is adapted to be adjusted within the outwardly-flaring end 4" of the casing I 44 to form the burner-opening. The valve 13 is securedto the rod- 12 by nuts 13 13".

the valve 13, Where it meets the air entering the mixing-chamber 2, the gas and air' being thoroughly mixed in this chamber before ,burnenopening atthecend thereof aroundx ,assing to the combustion-chamber of the urnace; When it is desired to increase the quantity of the gas, as in the caseofforcing the fire or when the gas-pressure becomes so low that suflicient gas is not delivered to-the furnace, steam iscaused. toenter the steamchamber 5 through theinlet 9' and from said steam-chamberis injected into'the gas-chamber 5 throughthe inclined'ports 10,"where it r will siphon or draw the gas entering through of the as regardless of the gas itse f, which will tend" to eep the quanorce the fire.
