WILLIAM CARL BUTTNER, OF CHICAGO, ILLINOIS, ASSIGNOR TO THE BASTIAII-BLESS- I ING COMPANY, OF CHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS BURNER.
' Application filed August 27, 1923. Serial No. 659,468.
As my inventionand the objects thereof can be best understood from the description of the embodiment of my invention illustrated in the accompanying drawing, I will proceed at once with the detail description thereof.
tudinal section through a burner'embodyi'ng the novel features of my invention, and Figs. 2 and 3 are sections taken on lines 2-2 and 3-3 respectively of Fig. 1.
The embodiment of my invention which is illustrated in the accompanying drawing comprises a nozzle 10 having an internally threaded inlet 11 adapted to receive a pipe section 12 which may be employed to connect the nozzle to a torch of the type generally employed in heating, welding, cutting, or otherwise treating metals by means r of a gas flame directed upon the work. The
burner which is illustrated in the accompanying drawing and which comprises the nozzle 10, is particularly adapted to be used in connection with a torch wherein means are provided for supplying the usual illuminating fuel or any suitable gaseous fuel to the burner, a suitable proportion of air being "mixed with the gaseous fuel to support combustion at the flame orifice of the burner. In the illustrated embodiment of my invention the mixture of combustible and combustion-supporting gases is fed to the burner through the pipe section 12 which communicates with a bore 13 turned in the nozzle 10. The bore 13 is turned to a larger diameter at its forward end to receive a tip 15 having acentrally disposed passage 16 which registers with that portion of the bore 13 which is of smaller diameter. The forward end of the passage 16 terminates in a flame opening 17 dis posed within the nozzle 10 and spaced from In the drawing, Fig. 1 is a central longi the flame orifice 18 of the nozzle. I prefer to provide the tip 15 with an annular groove 19 intermediate its ends to provide a chamber 20 within the burner, the chamber 20 being in communication with the passage 16 through the medium of a plu rality of ducts 21. The chamber 20 is also in communication with the flame orifice 18 by way of an annular passage 22 disposed concentrically with respect to the passage 16. It is apparent that part of the mixture of gases supplied to the burner will flow to the flame orifice 18 by way of the passage 16 and that theremainder of the mixture will flow to the flame orifice through the ducts 21, chamber 20, and annularpassage 22. The duets 21, chamber 20 and annular passage 22 are designed to permit expansion of the gases which traverse them and therefore they will feed a portion of the mixture supplied to the burner, to the flame orifice thereof under reduced pressure and correspondingly reduced velocity.
This construction is advantageous in that the mixture may be supplied to the burner under comparatively high pressures with out causing the flame to be extinguished. This is an exceedingly important feature of my invention for the mixture must be supplied to the burner under comparatively high pressures for some classes of Work and unless means are provided for feeding a portion of the mixture to the flame orifice under reduced pressure the flame will be extinguished. While the proportions of the various passages may vary considerably, I find that the best results may be obtained by having the sum of the cross-sectional areas of the ducts 21 approximately equal to one-fifth of the cross-sectional area of the passage 16 and by having the cross-sectional area of the annular passage 22 sub stantially equal to the cross-sectional area of the passage 16. While the chamber 20 may be dispensed with in some instances, I find it advantageous to'provide this chamber as the pressures of the streams of gases which flow through the ducts 21 may be equalized therein so that the stream of gases which flows through the annular passage 22 will feed all sidesof the flame equally.
Two distinct types of flame are obtainable with this burner. A large flame may be obtained by first opening wide the gas valve on the torch, then lighting the gas and I then very carefully opening the compressed air valve until a blue flame is produced. This flame will be rather feathery and will not show a distinct inner cone but will serve quite well for lead burning operations, etc. A smaller flame may be obtained by cutting down the air pressure and then reducing the gas flow to correspond. As the torch is turned down toward its minimum capacity, a point will be reached at which the outer edge of'the flame seems to burn back into the inside of the burner. The flame will then assume a well defined conical shape,
somewhat elongated, and the inner cone will This form of flame is well be very distinct.
' suited for the usual welding, soldering and burning operations, and is one which is not obtained by other burners now in general use.
I am aware that changes in the form, construction and arrangement of parts may be made Without departing from the spirit and without sacrificing the adyantages of the invention and I reserve the right to make all wardly from the end of said nozzle, said tip having a central passage therethrough and having an annular groove on its outer surface to form a relatively large chamber between said nozzle andsaid tip, the end of said tip being spaced from the sides of said nozzle to form a comparatively small annular passage communicating with said chamber, and said tip having a plurality of ducts leading from said central passage to said chamber, for the purpose set forth.
