Kemp Manufacturing Company, Baltimore, Md., a corporation of Maryland Application July 24, 1940, serial No. 347,122
(ci.15s1o4) 8 Claims.
This invention is directed to a burner peculiarly adapted to presenting a stiff knife edge, blade like or ribbon like flame, the ame having a high temperature and burning with considerable pressure to the gas. In the production of such a flame in other burners than this construction, the velocity of the gas exceeds the rate of ame propagation with the result that the flame gets so far from the gas source that it is blown out by the force of the gas itself and it is a purpose of the present burner to produce such a ribbon like blast ame of high temperature that will not go out.
. The burner is peculiarly useful in the soldering of tin cans, which are taken through a solder bath for soldering the side seams.- YThe seams l of such cans must be heated to a very high temperature so as not to extract heat from the solder bath and thereby cool it and yet this flame must Vbe so narrow and restricted in its width as not to heat appreciably the can body away from the seam.
In the production of such can bodies, on modern machines, they come through at such a rapid rate that the burners heretofore constructed have either heated too much of the can bodies or they have not been able to heat them suiciently to keep from extracting heat from the solder bath, through which they go. l
Of course other uses of the burner in which a knife edge flame of very high temperature is required are met with frequently in the industry and this example is only given by way of illustration of the utility of the invention.
The burner of the invention is an improve- -ment over the burner of the Patent No. 1,204,359
dated November '7, 1916, which has been tried and found not to produce sumcient heat `in the time allowed by certain rapid manufacturing processes.
Other objects and advantages of the invention will be apparent from the following description and accompanying drawings, which formv a part hereof, and in which:
Figure 1 is a top plan view of a burner embodying the present invention, with part of the top casting removed.
Figure 2 is a vertical sectional view of the burner.
Figure 3 is a side elevational view showing the multiple controlvalves. o
Figure 4 is a cross-sectional view on line 4 4 of Figure 2.
Figure 5 is a cross-sectional view on line 5-5 of Figure 2.
Figure 6 is a similar view on line 6-6 of Figure 2.
Figure 7 is a partial inverted plan view of the top casting of the burner.
Similar numerals refer to similar parts in the vseveral views. l
The burner consists of an elongate body I made up of two castings, a top casting 2 and a bottom casting 3.
These 'two castings are permanently attached together by bolts 4. The top casting 2 has a trough 5 in. its top section and in its bottom section a central longitudinally extending slot. 6 and lateral longitudinal extending slots 1. Central slot 6 has spaced orifices 8 leading therefrom to the center of the trough 5. Lateral slots 1 have sloped passages 9 forming orifices at their top opening on eachside of the orifices 8 in the bottom of the trough 5.
In the preferred construction the orifices 9 are arranged in staggered longitudinally extending rows as shown in Fig. 1, forming pilot llame orilces.
After cutting the slots 6 and 'I in the top casting 2, the lower portions of Athese slots are closed, the central one by plate I0 and the lateral ones by plates II. Plate I0 is drilled so that it has alternately sloped spaced passages I2 and plates II :are drilled to have sloped passages I3. These sloped passages equalize the pressure of the fuel and cause the fuel in its flow to impinge upon the walls of the slots 6 and 'I to further equalize the pressure so that a fuel is presented to the immediately above the entrance to the pipe I5A to divert the iiow of uid to each end of the chamber and toA prevent undue pressure immediately above the pipe. Lateral chambers I8 are also in this lower casting and these, when the castings are connected, connect directly with lateral slots 1 in upper casting 2 through passages I3. These passages I8 are fed by a pipe I9 through side openings 20 drilled into the casting. As the casting is formed `the fuel passes through opening 2| connecting the opening from pipe I9 with the openings 20 and the outer extremities 'of this opening 2| are closed by plugs 2-2, The now of fuel through pipe I9 is controlled by valve 23 and fuel passes through central pipe 24 to both valves I8 and 23'.
By this construction a ribbon like blast flame may be projected from the central orifices 8 under great pressure and it may extend some distance from the trough and the tendency ofthe flame to go out or be blown oil because of the pressure of the fuel is prevented by the supporting lateral pilot flames burning with less pressure from orifices 9, these side flames being sloped toward the center flame to give it greater support in burning. The structure permits a center flame of continuous sheet or ribbon like formation substantially withoutperceptible division into separate Jets and without high and low points or valleys and ridges, and as much ame and therefore heat as is possible is concentrated in a sharp knife-like line where it burns constantly. The concentration of heat is so great that one foot of this burner will supply as much heat as four or live feet of other available burners.
The separate control of the two flames allows for their accurate adjustment in relation to each other, and the main cut-olf can be manipulated without disturbing that control when the burner is shut down after use.
It will be apparent that modifications may be made in the apparatus to carry out the invention without departing from the principles thereof.
