GAS-BURN Specification of Letters Patent.

Application filled April 27, 1920. Serial No. 376,997.

T 0 all whom it may concern:

Be it known that I, J OHN FESTA, a citizen of the United States, and residin at Brooklyn, Kings county, and New ork State, have invented certain new and useful Improvements in Gas-Burners, of which the following is a specification.

This invention relates to gas burners and more especially to burners used in heaters and its object is to provide a mixing chamber with fices and extending upward from the chamber so that danger of back fire is eliminated and the flame is divided to permit of the the consumption of more oxygen while the mixed vapor is evenly distributed to each nipple, as willbe more fully described and the details enumerated in the following specification and set forth inthe appended claims, andthe device illustrated in the accompanying drawings, wherein:

Figure l is an elevation of the improved burner Fig. 2 is a vertical longitudinal sectional view of the same, v Fig. 3 is a plan view of the burner,

Fig. 4 is a cross sectional view onthe line 4-4. of'Fig. 2.

A serious objection to the burners com-. monly used in gas heaters is the danger of back fire in consequence of the proximity of the nipple to the gas inlet nozzle and the lack of air supply to all the gas jets often results in inefiectual combustion and-waste of gas. i i

To overcome these failures in burners as heretofore constructed, the mixing chamber of the device shown in the drawlngs is divided into two compartments 5 and 6, the latter receiving its supply of airand gas through the pipe 7, and from the inlet 8 and nozzle .9, of the supply pipe 10, to which may be secured suitable piping from the desired source. The nipple 9, is threaded and playing in the same, is the shield 11, that may be advanced toward the open end of the inlet 8, sufiiciently to regulate the supply of air and be secured to any adjust-' ment by the screw 12. r

The air and gas on leaving the pipe 7, are thoroughly mixed in compartments 5 and 6, by striking the partition 13, being deflected laterally and passing through the openngs, 14:, where on entering compartments 5, it 1s difiused o right and. left as its force is outlet nipples divided at their orispent against the upper wall 15, and between two of the nipples 16, at each side.

This arrangement of the mixing chambers insures a perfect distribution of the mixed vapor-to the nipples and where an identical volume of gas is furnished to each outlet. This can only be attained by supplying the vapor at a central point and not from one end and where the jets will decrease in size toward the other end of the burner and where the supply for the last nipple is so weak that it will not remain lighted but allow the escape of the gas to the room in which the burner is located.

The nipples 16'are made of short sections of pipe, threaded iand screwed into holes that are tapped in the wall 15. Across the upper end is fitted a partition 17, of thin sheet metal and this end is compressed and flattened so that there is an orifice for the escape of vapor on each side of the partition, thus providing for two parallel flames with space between them for the admission of air on both sides and .it is evident-that by closing the orifices will provide a flame of greater expansion and more adaptable for heaters where reflection surfaces are used.

It will be seen that with a burner constructed as above described and illustrated,

it will be practically impossible for a flame to descend through the nipples, the two compartments 5 and 6, and the pipe 7, to the nozzle 9 and fire the gas and supply at that point. It is also evident that the gas and air are evenly and thoroughly mixed in passing from the inlet pipe to the nozzles by the arrangement of the compartments 5 and 6,. and that the size of the jets is readily regulated by degree to which the nipples are compressed at their outlets.

Obviously the parts may be otherwise arranged and modified without departing from the essential features above described or from the scope of the appended claim.

What I claim as new is In a gas burner, the combination of a horizontal cylindrical pipe having openings along its upper side and closed at its ends, a mixing chamber integral with the said pipeand having at its separate ends a communicating open1ng,a vapor supply pipe beneath the mixing chamber andparallel with the same and the horizontal cylindrical pipe, nipples for the openings in the latter plpe and having slotted. orifices in line with and parallel with said horizontal cylindrical name to this specification in the presence of ipe, and a dividing plate 'in each slot two subscribing witnesses, this 20th day of adapted to divide the flame so that the nip- April, 1920. ples Will supply two separate and distinct JOHN FESTA 5 and continuous flames along the pipes and Witnesses:

mixing chamber. JAMES B. SLATTER,

In testimony whereof, I have signed my A. W.-BAKER.
