CACTUS BURNER Filed Oct. 4, 1938 Patentecl July 15, 1941 UETED ENT OFFICE 1 Claim.

My present invention relates to improvements in cactus burners such as is disclosed in my United States Patent No. 1,058,900, dated April 15, 1913, and is an improvement on that portion of the invention which is referred to in said patent as the burner proper.

It has been found that in the use of the device set forth in the patent mentioned there is a tendency for the outlet orifice of the burner to become clogged with scale, carbon, sediment, etc., necessitating more or less frequent cleaning. The present invention, therefore, has for its principal object to overcome this objectionable feature by providing a burner nozzle so constructed as to provide means whereby foreign matter such as that mentioned will be trapped and prevented from entering the fuel discharge tip of the nozzle from which trap it may be removed when desired.

In the drawing:

Figure 1 represents a side elevation of my complete cactus burner,

Figure 2 is a perspective view of the burner portion of the device with the casing thereof removed,

Figure 3 is a vertical section of the nozzle portion of the burner with the discharge tip in elevation,

Figure 4 is a perspective view of the discharge tip, and

Figure 5 is a vertical section of the same.

In the drawing, lil designates the fuel tank portion of my cactus burner, which tank is provided with a cap-controlled filling opening ll. Connected to the tank for supporting the same when in use is a strap [2 adapted to pass over a shoulder of the operator. Also connected to the tank is an air pump 13 for maintaining air pressure within the tank and upon gasoline or similar liquid fuel contained therein.

Leading from the tank Ill is a pipe l4 provided with a valve [5 for controlling the flow of fuel therethrough. Removably secured to the outer end of the pipe M is the burner portion of my cactus burning device, which burner portion comprises a metal pipe having a forwardly extending portion 16 reversely bent into a loop I! from which that portion of the pipe indicated at 18 extends substantially parallel to the portion l6, and screwed upon the upper or free end of the portion l8 and extending at right angles thereto is the burner nozzle l9 having a discharge tip 20. By referring to the drawing it will be seen that the tip 23 is so disposed as to discharge fuel between the portions 16 and I8 and the loop ll whereby when the fuel is ignited the various convolutions of the pipe will be maintained in a heated condition, thus converting the liquid fuel passing therethrough into combustible gas, as will be understood. To retain the burning fuel against said convolutions and to provide tion.

As will be noted by referring to Figure 3, the nozzle comprises a transversely extending portion 23 which connects two

hollow end portions

24 and 25 extending at right angles thereto in parallel relation, the interiors of which end portions are connected by a longitudinal channel 23a passing through the portion 23. Corre-' sponding ends of each of the end portions are open and each is interiorly threaded, the end portion 24 being thus screwed upon the free end of the pipe portion 18, and the threaded opening of the portion 25 having the discharge tip 20 screwed thereinto.

The discharge tip 20 comprises an exteriorly threaded plug adapted to be screwed into the end portion 25 as shown, which plug is bored through axially as at 26 to communicate at one end with the interior of the burner head and to provide at its other end an outlet for the fuel, which outlet is enlarged by countersinking, as indicated at 26". The inner end of the plug portion of the burner tip is somewhat reduced in diameter as at 21 and is provided with a transverse groove 28 across'its inner end face from side to side which groove intersects the bore 26 and extends the full length of the reduced portion.

As will be noted, the reduced portion 21 is spaced from the inner wall of the end portion 25, whereby said reduced portion is surrounded by a pocket 29 which serves as a trap to catch any foreign matter that may be carried to the tip by the fuel and that would otherwise clog the bore 26. This foreign matter may be removed easily by unscrewing the discharge tip.

What ,is claimed is:

A nozzle for cactus-burners comprising end portions having parallel threaded bores, a portion connecting said end portions at right angles thereto and having a passage therethrough in communication with the bores of the end portions, the threaded bore of one endportion providing means for attaching a fuel pipe, and a discharge tip threaded into the bore of the other end portion, said tip having an axial bore therethrough, said tip having a reduced portion extending into the bore of its supporting end portion and spaced from its inner wall in overlapping relation to an end of the passage through said connecting portion whereby to provide a sediment trap, said axial bore having an enlarged outer end portion, and said reduced portion having a transverse slot extending thereacross throughout its length and intersecting said axial bore.
