SBECIFICATION forming part of Letters Patent No. 293,972, dated February 19, 1884.

Application filed August 27, 1883. (No model.)

.To all whom t may concern.-

Be it known'that I, BRUNO MARTIN, of East Saginaw, in the county of Saginaw and State of Michigan, have invented new and useful Improvements in Hydrocarbon-Burners; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, which form a part of this specification.

This invention relates to certain new and useful improvements in the construction of 'hydrocarbon-burners, by means of which a great spread is given to the iiame and a more perfect combustion obtained than can be had in Athe use of devices for this purpose as ordinarily constructed. This improved burner Will be found very beneficial in the consumption of hydrocarbons in a vaporized form, where an intense heat is desired-as, for instance, in stoves either for heating or cooking purposes, under boilers, and in many other places-with great economy in the amount of the hydrocarbon used.

The invention consists in the peculiar construction of the various parts andtheir combination and operation, as more fully here! inafter described.

Figure l is a central vertical section of my improved burner. Fig. 2 is a horizontal section on the line X X in Fig. -l.

In the accompanying drawings, which form a part of this specification, A represents a shell, open at bottom, and provided with an inwardly-deflecting flange, a, at its top end.4

B is an inner shell, shorter thanl the shell A, also open atbottom, and also provided at top with an inwardly-deiiecting flange, b. These two shells are arranged with relation to each other, as shown, having a free air-space between them.

C is an interior shell, in the form of a truncated cone, the lower end flaring outwardly, as shown, open-at top and bottom, and at top also provided with an inwardly-deflecting ange, c, and arranged toform a clear airspace between it and the shell B.

D is a heavy metallic cup, preferably made of brass, with a concave bottom, as shown, between which and the vertical sides of the cup the sides are also concave. This cup is internally threaded, and is provided with a flanged and threaded plug, E, which screws into and forms a cover for the cup.

F is a pipe cast with or attached to one side of the cup, projecting through the shells A B C, through coincident holes for the purpose, and the projecting end of this pipe is closed by a plug, G. r l

H is a feed-pipe passing throughcoincident holes in the three shells opposite the pipe F, and is screwed into the side of the cup, as shown, in axial line with the pipe F. A connection between the two pipes and through the cup is formed by means oi' a perforated pipe, I.

J is a branch pipe leading from the pipe F down between the shells A and B to the burner K, which is provided with a pin plug screwed into the burner, of the usual construction, and the burner is also provided with a cup, L, to `receive alcohol or its equivalent, setting re to which vaporizes the hydrocarbon in the burner and ignites it.

M is a metallic ring-plate laid upon the top of the cup before the plug E is screwed on. This ring projects beyond the top of the cup, to form; a dellecting-flange between the deflecting-anges b c.

N is another similar ring, laid upon the ring M, and its edge is turned upwardly and out- 'ward to meet the lflat metallic plate O. After the two rings are in position, the plug E is screwed to place, andl holds said rings in position. The plate O is then laid upon the top of the plug E, said plate projecting beyoud the upwardlyprojecting edge of the ring N. Another plate, I), with its periphery bent upwardly and outwardly, is placed to meet the plate Q, which projects beyond the flanges of the plate P, just below the plane of the deiiecting-langes a. cured to the top of the plug E by means of the screw R, a hole being tapped into the top of the plug for'that purpose. The cup is filled with any suitable granulated refractory material, which serves to check the too rapid flow of the hydrocarbon through the cup, and the pipe H, being connected with any suitable source of supply filled with hydrocarbon, the latter is discharged into the cup through the perforated pipe I, when it is absorbed by the refractory material which lls the intervening The plates Ol? Q are se- IOO space, thus exposing the hydrocarbon to a large area of heated surface, which is thereby quickly and thoroughly vaporized by the heat from the burner, the vapor or gas iinding an outlet through the pipe J to the burner. The

iiame is inclosed within the shell C, which directs such flame against the bottom of the cup,-

the concavities in the bottom of which tend to spread the name around the cup and to the annular passage formed by the deflectingiianges c, and thence through the tortuous passage formed by the -rings M N, plates 0 l? Q, and deflecting-la'nges (6?),the spaces between the shells furnishing the necessary amount of oxygen to produce the most perfect combus- A tion, so that no smoke or smell arises as the result of imperfect combustion.-v

In the construction described, the shell'sfare supported by the pipes F H. 'Io provide against any accidental displacement, a stay,S, is run through coincident holes in such-I shells, the end of such stay being screwed into a hole' tapped in the wall of the cup' for that purpose, as shown in Fig. 2,

I deem it important that the chamber D be arranged centrally over the burner, for by this means the hydrocarbon, in its passage through l necting such supply and eXit pipes, and refractory material around said perforated pipe, substantially as set forth. p Y

3. In a hydrocarbon-burner, horizontal de-A ectors in vertical series, with inclined vde.

flcctors interposed between them, in combination with a vaporizing-cup, substantially as and for the purposes described. n

4. In a hydrocarbon-burner, a vapori-zingcup provided with suitable inlet and outlet pipes and a plug secured therein, performing the double function of forming a cover for the cup and holding the plates M and N between the projecting iiange of said plug and top of the cup, substantially as specified.

5. In a hydrocarbon-burner, the combinaf tion of a vertical series of horizontal deflectors with vertical annular ducts, forming airpassages to the iiame in its passage around said d'eiiectors, substantially as described.

6. In a hydrocarbon-burner, a vaporizingcup formed with a concave bottom and sides,

in combination with an inclosing-shell, substantially as and for the purposes specified.

7. In a hy drocarbon-burner, and as a means for producing an undulatingA or tortuous flame, the combination of the horizontal deilectors, @in vertical series, withthe deiieeting-ilanges of the-inclosingshells.l forming the air-ducts,

substantially as set forth..

8. The combination, with a vaporizi-ngcup and hydi oearbon-burner, of the inner conical shell or ring-duct provided with a deiiectingf flange, for the purpose of guiding and deflect- 1 ing the flame against the bottom and side walls of such cup, substantially as described.

9. In a hydrocarboneburnenfa vaporizing-A chamber lled with granulated refractory material, such chamber being arranged centrally over the burner,rand communicating therewith by a pipe, and adapted to receive `the hydrocarbon from any suitable source, 3 substantially as specified.

10.- In a hydrocarbon-burner, a series of `annular airducts of graduated size, concentrically surrounding the burner, and each provided at top with an inwardly-projecting deflecting-iiange, for the purpose of supplying oxygen at succeeding intervals to a flame` substantially as set forth. y 1l. A hydrocarbon-burner consisting of the shells A B C, with their iianges a. b c, vaf porizing-cup D, plug E, pipes F H I J, burner K,vrings M N, and plates O P Q, the parts being constructed, arranged, and operating substantially as and for the purposes described.
