,'To all whom it may concern:

Be it known that I, HENRY E. SHAFFER, of Rochester, in the county of Monroe and State of New York, have invented certain new and useful Improvements in Burners fo" Acetylene Gas; and I dc hereby declare the following to be a full, clear, and exact description .of the saine, reference being had to the ac companying drawings, forming a part of this specification, and to the reference-numerals My present invention has for its objects to lprovide an improved burner for gas rich in carbon, such as acetylene gas, whereby notonly will the light bc improved and more perfeet' combustionl had, but the dame will4 be free from the fluctuations due to variations in pressure of the gas and to these and other ends the invention consists in. certain im` provements hereinafter fully described, the novel features being pointed out inthe claims at the 4end of this specificationl In the drawings, Figure l is a side eleva- `tion of a Agas-lnirner constructed in accordance with 'my invention; Fig. 2, a vertical view'of a modification; Fig. 4, a horizontal sectional view of the burner shown. in Fig. 3; Fig. ,15,-a cross-sectionalview on ,the line a: o: of Fig. 2.

Similar reference-n u merals indicate similar i parts.

l .be transmitted to the burner-body, I reduce' In Figs. l and 2 I have shown the preferred form of burner, consisting generally of a body vportieri l, preferably of metai, having a gaspassage f3, a central chamber Eaand also an upwardly-extending external projection 4, preferably formed with the. burner-body and projecting between and preferably 'close to the under sides ofzthe flames from two burner-v tips 5, arrangedwith their gas-orifices atan angle to eachother and receiving gas' from the central chamber 3." The object of the projection 4 is'to providea mass of material below the point of cooperation of two gasjets impinging at an angle, which will become heated'by proximityto the 'flames and will in turn' react np'on the gas and promote its'combustion and heat the air 'that reaches the- :Ilame from below. 'In order that as little of the heat of the projection 4 as possible shall the supporting portions thereof as much as possible by cutting away the metal beneath it, as at 6, leaving only the narrow supporting-arms 7, which are strong enough to hold the projection, but oder a veryvsnlall heatconducting surface.

The burner-tips 5 are each constructed of soapstone, lava, or similar refractory material and are preferably provided With two passages 8 and 9, the former, constituting the entrance-passage, being in communication with theinterior of the chamber 3, and the latter, being the discharge-passage, extending at an angle to the former and communicat-- air-passages, which insures the air entering the passages striking the column of gas at rightangles and when it first issues from the aperture l0. 'I prefer to form the passage 9 by drilling in from the outer end of t e tip. Then lthe minute aperture 10 is drilled, and then the passages 1l are formed by passinga larger drill through from side to 'side of the tip, the center of said drillbeing about on a level with the bottom of the passage 9, as will be understood from an inspection of Figs. 2 and 5.

Near the outerend of the passage 9 are provided verysmall lateral passages 12, serving to admit air to the column of mixed airand` `gas near the point of combustion, effectually surrounding it andY preventing Contact with the extreme end of the tip, thereby prevent ing undue heating of the latter and the formation of a deposit thereon. Tips. thus constructed l find give very good results and insure the consumption of al1 of the gasA without causing the deposits which sometimes impair vthe eiiiciency of burners of this class, and by the arrangement of the passages vil and 9 at an angle, as shown, thc tips may be readily employed not only in the form of burner shown in Figs. 1 and 2 for producinga flat name,

2 l "swab but. also to produce separate vertical jetsyas shown in Figsf'B and 4, as will be described.

. The burner shown in Figs. 1 and 2 not only is well adapted for use in connection with the particular form oftip shown, but the feature of having/a central gas-chamber 3 and the gas-,passages tothe tip out of line with the inletypassages is particularly advantageous, because the flame is relieved from fluctuaio tions due tovariationsin the pressure of the gas, the gas contained inthe chamber -forming a cushion to some extent an'd insuringV a comparatively even supply'to the dame, and.

the angular arrangement of the passages' i5 and 9 in the tip contributes also to this result. y i

While it is'de`sirable to' have the -buruertips herein shown and described arranged at an angle to produce a flat flame, they Vare capableof use in a humor-body of the forni of that shown in Figs. Baid 4, in which the upper portion (indicated by is provided with horizontal radial apertures adapted .to receivethe tips, the passages 9 being verti- 215 cally arranged to produce a seriesof vertical flames, and while I have shown four tips attached any number desired could be emplyed. In this construction also it will b e noted that the interior of the body constitutes 3o a chamber and the passages in the tips are not in a direct line with the inlet-passage 21, so that the flickering -of the 'llame due to variations in pressure is materiallyrednced. n The tips couldV be molded or otherwise formed, if desirable, and the specific form changed without departing from the spirit of my in venton; but-I 4prefer that the channels Band 9vbe ai angedat an angle, as shown, as l this feature prevents undue flickering by reason of-the change in direction of the dow of gas and also facilitates the application to the forms of burner-bodies shown herein. I

I claim 'as my ifventiony i y l 1. In a bui-nerv for 'acetylene and similar gases, the combination with the burner-body having the `tapering extension and the round gas-apertures discharging gas'in converging streams above the extension and substan#V tially parallel with the faces thereof, therebyucausing ltheextension to be heated by the Haines.

3. The combination with the `burner-body -irst issues into the passage.

and the burner-tips discharging gas in 'een verging streams above the body, of the ex tension formed on' the body and arranged be-l tween the tips and having aI narrowr connesa of, tion with the body to prevent conduction of, heat to the latter. l
