OTTO J'. GROEHN, OF DETROIT, MICHIGAN. ASSIGNOR TO CLAYTON & LAMBERT MANU- FACTURING COMPANY, OF DETROIT, MICHIGAN ,f- A. CORPORATIONOIF MICHIGAN.
OIL BURNER.
Application filed October 6, 1919. Serial No. 328,835.
.To all whom t may cof/mera.'
Be it known that I, OTTO J. GROEHN, a citizen of the United States of America, residing at Detroit, in the county of Vayne and State of Michigan, have invented certain new and useful Improvements in @il Burners, of which the following is a specilication, reference being had therein to the accompanying drawings.
The invention relates to oil burners and more particularly to that class designed foil use on blow torches. It is the object of the invention to obtain a construction in which clogging of the burner is prevented so as to maintain the same in operative position. To this end the invention consists in the construction as hereinafter set forth.
In the drawings:
Figure l is a longitudinal section through the burner;
Figure 2 is a cross-sectiony on line 2--2 of Figure l; and
.Figure 3 is a cross-section on line 3-3 showing the operation of clearing the jet from obstructions.
A is a fitting having an internally threaded nipple B for Connection with the liquid fuel supply pipe (not shown). C is a portion of the fitting extending laterally from the nipple B and containing a passage D. E is a valve for engaging a seat F controlling communication between the nipple B and passage D. G is a passage through the portion C intersecting with the passage D at its forward end and returning to a point substantially in alignment with the nipple B. H is a jet nozzle communicating with the passage G, said nozzle being preferably formed of a separate fitting having a threaded shank I engaging an internallythreaded nipple J on the tting A. K is a mixing tube surrounding the nozzle H being provided with apertures or slots L for the admission of air.
"With the parts as thus far described the opening of the valve E will admit the fuel from the nipple B to the passage D and communicating passage G and from the latter to the jet nozzle H. When the burner is in operation, the heat conducted therefrom intothe portion C of the fitting is suliicient to vaporize the liquid fuel in the passages G and D, so that only vapor the jet port.
will be discharged from the jet H and will be directed axially through the mixing tube K. Here it will be commingled with air so that the resulting mixture will burn with a blue flame. It is, however, a frequent occurrence that some sediment carried by the liquid fuel will be carried to the tine aperture of the jet tube, where it willY lodge and obstruct the flow of gas. l/Vith certain construction heretofore used conical pointed valves, or so-called needle valves, have been arranged at the jet nozzle, but these are insufficient to prevent clogging of the jet port and also have a tendency to enlarge the aperture therein.
IVith my improved construction clogging of the jet tube is prevented by arranging in rear thereof a screw-threaded stem L which carries at its forward end a cylindrical needle M of a size that will pass through This jet port is formed in the head of the fitting I and is preferably cylindrical with flaring resistance at opposite ends thereof, the bore of the port being preferably the same as the diameter of the cylindrical needle M. It is obvious that the latter wheny moved forward may be passed completely through the port, so that any obstruction therein will be entirely dislodged. Thus, in operation whenever there is the slightest clogging of the jet, the screw-threaded shank L is turned by Ameans of a suitable handle N forcing the needle M through the port H and is then turned back to withdraw the needle, leaving the port freed from obstruction.
1What I claim as my invention is:
In a blow pipe torch for developing intense heat, a flame tube having an open forward end and air passages into the tube in the rear of said forward end, a vapor discharge nozzle at the rear end of the tube and substantially in alignment with the axis thereof, said nozzle having a discharge port, a stem in alignmentV with the axis of said discharge port and adjustable toward and from said discharge port, a support for said stem, a cleanout member carried by said stem and adjustable through said olisvcharge port, said stem and cleanout member being adapted to be withdrawn entirely from said support, said stem remaining in alignment with the axis of said discharge port during the withdrawal thereof, a vaporizing passage leading from a source of supply of fuel to the port of said discharge nozzle, and a valve for controlling the supply of fuel to said Vaporizing passage 10- 5 cated at a position remote from said discharge nozzle, said valve having a stem provided With a screw-threaded adjustment for positively forcing the valve to its closed position independent of said stem which is adjustable in relation to the port of the dis- 10 charge nozzle.
In testimony whereof I affix my signature.
loTTo J. GROEHN.
