BURNER FOR TORCHES AND THE LIKE.
Application filed May 8,
: all whom it may concern:
Be it known that I, HARRY J. Anonason, a citizen of the United States, and residing in the city of Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented or discovered the new, useful, ant
Improved Burners for Torches and the like,
of which the following is a specification.
Myv invention consists in a new, and improved. burner for bench and hand torches,
plumbers torches and furnaces, rivet heating furnaces and the like.
The object which I have in view is a new and improved burner for pumpless torches,
heaters, furnaces and the like, which will work with gases of low compressibility; -which willproduce a steady flame without pulsations, and which will produce very high temperatures suitable for brazing and such work.
Generally speaking my improved burner is characterized by the disposition of the fuel supply tube relative to the nozzle so that the gaseous fuel is preheated to a hitherto unknown degree before being discharged into the nozzle. For this purpose I lead the fuel supply tube-forwardly along the nozzle, then crossing over or under the same and then rearwardly along and to the rear of the rear of the nozzle. I
Other novel features of construction and arrangement of parts will appear from th following description.
In the accompanying drawings, which are however merely intended to illustrate practical embodiments of the principles of my invention without limiting the scope thereof to the construction shown, Fig. 1 is a broken side elevation of a bowl torch in which my invention is embodied; Fig. 2 is a rear elevation of the same with the bowl broken away; Fig. 3 is a plan view of the burner; Fig. .4 is a side elevation showing my invention embodied in a hand torch; Fig. 5 i a rear elevation of the same; Fig. 6 is a top plan view of the same, and Fig. 7 is a broken diametric section of the post and the top fitting of the same.
The following is a description of the drawings, reference being first had to Figs. 1, 2 and 3.
A represents a bowl or reservoir for the nozzle, so that the fuel is admitted to the- Serial No. 637,412.
gases in liquid form. B is the post or stem which supports the burner proper, and
which may be mounted on .the bowl, and
and is connected at its upper end with a horizontal passage 2 which extends through the horizontal portion or head of an inverted T-shape extension C of the post B near the upper end of the latter. This extension, C may be brazed to the post B. 3 is a vertical passage in the vertical leg of the extension 0. Between the passages l and 3 the passage 2 is provided with a valve seat 4; adapted to be closed by the needle valve D, mounted onthe extension G, and thus controlling the supply of fuel to the passage 3.
E is the fuel tube having its inlet end detachably connected to the stem of the extension C, as by the screw coupler 5. The other or discharge end of the tube E is provided with the detachable, perforated burner tip F, thereby supplying fuel to the burner.
The outer or discharge end of the nozzle G is preferably taperedor contracted, as at 6, to better project the flame, and said noz zle is also provided with air ports, 7.
' The rear end'of the nozzle G is provided with the spider or head 8 provided with an axial orifice or port 9 through which the tip F extends. Thesaidport is preferably threaded for a purpose to be described.
The nozzle G is supported in a horizontal position, preferably by the bent tube The tube E is bent to extend forwardly along the wall of the nozzle G, then across the tapered or reduced discharge end of the nozzle, either over or under the same, and then rearwardly along the wall of the nozzle to the rear end of the latter where said tube is bent inwardly and then forwardly, axially of the nozzle so that the tip F will be positioned at the orifice 9. and removably support the nozzle, the same may be provided on either side near its rear end with the hooked projections 10, which engage the tube E from above and at its top front with a projection 11 which en To conveniently gages from above the transverse portion of the tube E. I
It is also evident that the gas traveling through the tube E will be heated by its show my burner applied to a torch, the post B is provided with a cylindrical hand g "asp l2 and the lower end of the passage 1 may be connected by a valve coupler H 'with a tube 13 which connects to abottle or other reservoir for gas.
In this case I have shown mounted on the upper end of the post B a fitting I which may be connected by the screw coupler J with an interposed asbestos washer 14-, thus preventing overheating the handle.
The discharge end of the tube E is connected by a screw coupler 15 to the outer end of a radial passage 16 in the fitting 1, which passage connects at the axis of the fitting with a second radial passage 17 to whose outer end is connected the burner tip F by the nipple 18. The fitting I is also provided with an axial passage 19 wh ch extends down from the top of the fitting to the passage 16. The upper end of said passage 19 is normally closed by the nipple 20 and the screw plug 21, but when 1t isdes1red to project the burner flame in alinement with the post B, the plug 21 is removed and the tip F substituted. To enable the pro-per positioning and mounting of the nozzle G, in such case I prefer to provide the upper r end of the nipple 20 with exterior threadsupon which is screwed the threaded orifice 9 in the butt end of the nozzle.
When the burner is directed axially of the stem, as indicated in dot-ted lines in Fig. 4:, the tube E is bent to pass upwardly along the nozzle at one side, then cross over the same and then downwardly along the other side of the nozzle to the fitting I.
K is the frangible pressure disc device to provide for automatic relief for the passage 1 from dangerously high pressures.
It is evident from the foregoing that the pressure of the gas in the supply tube E will be magnified by the heat radiating from the nozzle so that the gas will be discharged at increased velocity into the rear end of the nozzle tube. This increased pressure will assist in drawing fuel up through the stem or post B. By passing the liquid or partially liquid fuel through the preheating portion of the tube E, before it enters the nozzle, all the liquid elements are completely gasified, and a greatly magnified heating value is obtained, and the burner flame is much more steady and intense. Thus the entire liquid contents of the bowl or reservoir, when wet gases are used as the fuel are gasitied and consumed.
By loosening the coupler 5, the tube and nozzle may be dismounted, thus increasing 1 place in the saddle,
said passage comn'n-nricates with the convenience of the burner and facilitating repairs. \Vhere the nozzle is mounted in alinement with the post 15, the nozzle may be readily unscrewed from the nipple 20.
Although. for the sake of clcarncss in illustrating the principles of my invention I have described in detail the Gll'lbOClllllEl'ltS thereof shown in the drawings, I do not wish to limit myself thereby, but claim broadly 1.
