BURNER.
Application filed November 17, 1926. Serial No. 148,917..
My present invention relates to burners, and has for its principal purpose to improve burners of the kind disclosed in my United States Letters Tatent No. 1,588,634, dated June 15, 1926, although it will be plain that features of my present invention are applicable to various other burners adapted to use liquid, gaseous or powdered fuel.
In particular, l desire to provide for controlling the flow of air between the nozzle and the cooperating, reversible ring mounted therein. Another purpose is to improve the mechanism whereby the nested fuel tubes are cleaned when firing is stopped. Another purpose to provide suoli a valve stem or other member extending through the inner fuel tube as will cause the air, fuel or both passing through said tube to issue therefrom with a whirling motion. Another purpose is to provide improved means for supplying and straining the oil, and a still further pur pose is to mount the burner rotatably, whereby the flame may be played in any desired direction. Another purpose is to provide a better adapted and improved mechanism for shifting the nested tubes. Still another purpose is to provide au air connection between the air supply pipe and the rear end of the luel tubes.
rlhe invent-ion resides in the elements, fea tures and combinationsclaimed in the appended claims, and now, in order, that the invention may be fully understood and readily put into practice, the same will be described with reference to the preferred ernbodirneuts shown in the accompanying drawings which, it is to be understood, are only for the purpose of illustration, so that my invention includes all changes and modifications as fall, within the scope of said claims.
In said drawings:
F igurc 1 is a view, partly in vertical longitudinal section and partly in side elevation, of the improved burner constructed in accordance with my present invention.
Fig, l is a side elevation of a cap nutadapted to close the rear end of the inner fuel, tube when the burner is operated without a valve at the nozzle end of said tube.
Figure 2 is a sectional view of an oil filter and connections for supplying oil to the fuel-conveying tubes of the burner.
Figure 3 is a transverse section through the burner, showing in elevation certain air valves for the nozzle.
Figure 4: is a fragmentary sectional view of the forward part of the nozzle and the fuel-conveying tubes, showing a modied forni of valve stem.
Figure 5 is a fragmentary sectional view of the forward part of the nozzle and the fuel-conveying tubes, showing a modification in which there is no valve cooperating with the inner fuel tube, said tube containing a helically twisted element, adapted to cause the gases or powdered fuels conveyed by the flow of air through said tube to take a tortuous or helical course.
As in my aforesaid patent, the burner in the present instance comprises an elbow 1, into which is threaded a sleeve 2, appropriately coiu'iected with a nozzle 3. An air conduit 5, preferably stationary, leads to the lower opening in theelbow 1, and the burner is supported on this air conduit. Air may be supplied through said conduit, at any desired pressure, by a fan, blower or other source.
Two telescoping or nested tubes 6 and 7 entend centrally through the nozzle and through the horizontal turn of the elbow, passing through the rear vertical wall thereof. `.lhe space between the outer tube 6 and the inner tube 7 constitutes a fuel passageway, and the space within the inner 'tube also constitutes a passageway t for fuel as well as for air. A rod or stem 8, within the inner tube, has a valve 9 at its forward end, and a deiiector plate 10, having a partly spherical rear surface, is secured to the end of tube 7, said plate providing a valve seat 11 to cooperate with valve 9, and a valve seat l2 to cooperate with a replaceable sleeve 13 secured to tube (5. A ring 14 having a conical inner surface 15 surrounds the atom izcr or plate 10, and is held slightly spaced from the inner wall of the nozzle 3 by pins 16 preferably three in number.
.iin interior-ly threaded bushing 17 secured in the wall of the sleeve 2 receives pipe sections 18 and 19, and the latter supports a iour-way joint 2O through which extend the tubes (l and 7. These tubes and the valve stein 8 are permitted to slide but held against rotation with respect to lthe joint 2l) by means of a pin (not shown) extending from the joint 2() into a slot formed in the side of the tube 6. The tube 6 also has two slots more to facilitate the commingling of fuel or air, and for cleaning purposes. The two tubes with the valve stem and atomizing plate l0 are adapted to be axially ing to support the tubes, and including av nozzle, its third passage Connected with a four-Way iitting which is disposed outside drain-off pipe, and its fourth passage oonthe nozzle and supported thereby, said fitneeted with. said drain-oli' pipe through a 10 ting` containing a valve, and having its first by-pass.
passage Connected with a 'fuel supply pipe, ln testimony 'whereof I a'f'l'ix, my signature.
a sediment trap and a strainer, its second passage connected with the tubes and the LUDVIG VALLSTROM.
