Description
Dec. 3, 1929 v A. v. RIGBY LIQUID FUEL BURNER NozzLE Filed Jan. 5, 1928 Inventar Patented Dec. 3, 1929 UNITED STATES PATENT OFFICE ALBERT V. RIGBY, OF SHARON,`PENNSYLVANIA, AS'SIGNOR ONE-HALF '.IIO` CARL J. MEHLER, OF SHARON, PENNSYLVANIA LIQUIn-FUEL-BRNER NozzLE Application led January 5, 1928. Serial No. 244,757.
The present invention relates generally to liquid fuel burners and more particularly to the nozzle thereof and has for its prime object to provide an automatic and hand cleaning mechanism.
Another very important object of the invention resides in the provision of ay nozzle of this nature which is simple in its construction, inexpensive to manufacture, strong and, durable, not likely to become out of order, easy to adjust, thoroughly efficient in use and operation, and otherwise well adapted to the purpose for which it is designed.
With the above and numerous other objects in view as will appear as'the description proceeds, the invention residesin certain novel features of construction, and in the combination and arrangement of parts as Will be hereinafter more fully described and claimed.
In the drawings:
Figure 1 is a longitudinal section through a burner embodying the features of my invention,
Figure 2 is a detail transverse section through the nozzle taken substantially on the line 2-2 Figure 1, and
Figure 3 isa detail side elevation of one end of the nozzle.
Referring to the drawing in detail it will be seen that the numeral 1 denotes the nozzle body which is of an elongated construction having a longitudinally extending bore throughout its length. This nozzle tapers from one end toward the other and is provided adjacent its larger end with an exterior annular shoulder 10 and with threaded portions to each side thereof. The smaller end of the nozzle is' beveled oil" and provided with 15. A restricted end 16 is threaded about the outlet end of thevduct ,14 and a similar member 17 is threaded about outlet end of the duct 15. A cap 18 is threaded on the casing and partitioned as at 19 so that air or steam from pipes 20 and 21 may be led respectively into ducts 14 and 15. The major portion ofthe nozzle body 1 extends into the casing and into the passage 14. This nozzle body is threadedly engaged in the casing with the annular shoulder in abutment therewith. A T 2' is threadedly engaged on the larger end of the nozzle body 1. A cap 3 is screwed infto the opposite ,end of the T topreventthe escape of fume and has a stuffing box 4 thereon through which is slidable a rod 5. A fuel pipe 22 is threadedly engaged in the' T 2 for delivering liquid ,fuel thereto. A valve stem 6 is slidable through the bore of the nozzle body 1 having the centralizing spider 7 thereon. A valve 23 is mounted at the end of the stem 6 to close over the smaller end of the nozzle 1. The nut 9 is threaded on the other end of the stem 6 and a compression spring 8 is disposed about the stem impinging against the larger end of the nozzle body 1 and the nut 9. Obviously the nut 9 may-be adjusted for changing the tension of the Aspring 8. u
The llow of the fuel from the pipe 22 extends through the T 2 and the bore of the nozzle 1 and the pressure will unseat the valve 23 lif sufficient to overcome the tension of the spring 8. An idling amount of fuel4 vary the discharge ofv the fuel through the nozzle and out at the angular outlet affordedv by the valve 23 at any desired pressure. The series of V-shaped notches 11v flaring youtwardy greatly facilitate the passage ofv smaller particles..y In case` the lV-shaped notches in the' chamber become partially or f totally closed, pressure automatically builds It is thought that the construction, opera-I tion and advantages of this invention will now be quite apparent to those skilled in this art without a more detailed description thereof. The present embodiment of the invention has been disclosed in detail merely by way of example since in actual practice it attains the features of advantage enumerated as desirable in the statement of the invention and the abovedescription.
-Having thus described my invention, what I claim as new is:
. A nozzle ofthe class described comprising an elongated body having a longitudinally extending bore extending from end to end thereof, one end of the body being provided with a plurality of notches, a valve closable over said end of the body, a stem extending from the valve through the'bore, spiders on the stem to centralize the stem in the bore, a spring about the stem, a nut threaded on the stem at the end remote from the valve, said spring impinging against the other end of the body and the nut to urge the valve toward the first mentioned end of the body, a T threadedly engaged 'on said other end of the body, a cap threadedly engaged in the T, a stuing box in the cap, a rod slidable through the stuffing box in alinement with the valve stem.
I' In testimony whereof I aIix my signature.
ALBERT V. RIGBY.
