APPARATUS FOR AND PROCESS OF BURNING GAS.

Application filed. September To all whom it may concern: v

Be it known that I, Gnononh'ltnlonnntm,

a citizen of the United States; residing at New Haven, in the county of New Haven 5 and State of Connecticut. have invented certain new and useful Improvements in Ap ,pnratus for end Processes of Burning Gas,

of which the following is a specification.

This invention relates to improvements in the process and apparatus for burning gas or gaseous, mixtures, and has for its main object'to provide apparatus and process of this nature which will permit direct burning and combustion of gaseous fuel r0 er. P O i'dinarily in the combustion of gas mixed with air it is necessary to supply the mixture at a comparativel slow rate to the burner to permit proper.

y process and the burner. In-, i1tilizing 'pply the 'comapparetiis,l am enabled to the combustion thereof, or inan' epropagation; otherwise the flame willbehlown out from Specification of Letters Patent.

Fig. 8 is a. side elevation of the burner tubegand 1 Fig. 9 1s a front elevation of the same. Like pnumerals refer to like elements throughout the drawings, in which- 9 indicates generally an air supply" ipe having a. valve 9" to control-flowof air therethrough, and terminating at and connected to aT 9". 10 is a gas supply duct or pipe having mmating in and attached to the T 10". Attached tov these Ts owns 10" is the main ortion, as his ductis provided with a tapered-nozzle portionll" the controlling valve 10 ter- I projecting forwardly .of the gas duct 1 0,-

Still another cb ect isto provide a burner of a tubular nature in which theconibustion of thccombustible mixture will-take with thwair 'soas to secure theniosti eiiiwhich pipe in turnjis threaded into a cou-' the other end of which is en-w ling 12,

arged, as indicated by numeral 12. In'this I enlargedend is threaded thepi pe or tube section 13, at one end of which is a burner disk or plate 14, having the .cen-' trally located aperture 14" therethrough' and the: outwardly projecting flange or boss 14" provided with the apertures or notch li -see Figs. .4 and 5, for exampl. Altermate of these notches 14 are larger in size,

. as shown in. Fig. 4. (A peripheral groove place, such combustion being arranged to trully located portion of the interior of a burner, which enables me to secure a burner core of high temperature without melting" or unduly heating theburner tube.

These and other. objects will be more fully set forth and dcscribed'ijn the follow ing specification,

Byarranging the notches burner tube, as will be apparent... At the same time the'fiame in said. tube' is directed toward the longitudinal. axis thereof, away 'from the inner walls-0f the some, so that I can obtain an axial core or focus for the flame, which may be of high te 1nperaturein fuct higher than the melting point of the tube 15, the mixture currents flowing along the inner wall thereof serving to prevent overheating of the tube.

Another feature of my invention is being able i-O'COlltiOl the flow. of the flame out \vardly of the ignition oint by means of the shut-off cock 16, as 1t will be apparent that when the same is closed during coin- .bustion the. pressure will immediately liSL in 'the burner and communicating duets, offsetting the pressurdof the supply, so
