LIQUID-FUEL BURNER.
SPECIFICATION forming part of Letters Patent N0. 751,092, dated February 2, 1904.
Application filed May 29, 1903. Serial No. 159,302. (No model.)
To all whom it may concern:
Be it known that I, DOSIER H. HosTELLER, a citizen of the United States, residing at San Francisco, in the county of San Francisco and State of California, have invented certain new and useful Improvements in Liquid Fuel Burners, of which the following is a specification.
My invention relates to improvements in oil-burners, being of especial value for use with furnaces for heating hotels or apartmenthouses or for cooking-ranges for restaurants or the like, and is an improvement upon that disclosed in United States patent granted to me January 20, 1903, No. 718,859.
One object of my invention has been to provide. a construction in which the elbow, and indeed all the parts subject to destruction by heat, can be renewed in a moment and without seriously interrupting the heating or cooking. Furthermore, I have found that when oil is used containing asphaltum or other heavy ingredients a portion of these residual products crystallizes and carbonizes on the sloping plate below the elbow. On my former device this could not be cleaned without extinguishing the fire, and then it was difficult on account of the heat.
A further object of my invention therefore has been to provide a constuction by which the auxiliary heating device for heating the elbow can be removed while the fire is burning and also one in which a crooked poker can be inserted to clean the entire rear side of the elbow without reducing the fire.
In the invention disclosed in said patent there was provided an outer box surrounding the elbow. I have found that this outer box to a certain extent smothers or reduces the effect of the draft and also creates a narrow space in which soot or carbon gathers, which obstructs and in time entirely cuts off the lower draft, causing an impairment of the efliciency of the burner. In my present invention I avoid this disadvantage.
The main objects of my invention, therefore, are to provide increased efficiency in the burner, to enable it to be more easily cleaned, and the parts which are subject to burning to be readily renewed without materially reducing the heat.
In the accompanying drawings, Figure 1 is a longitndinal section of my improved burner. Fig. 2 is a perspective view of the elbow-support. Fig. 3 is a perspective view of the elbow. Fig. 4 is another perspective view of the same from a different point of view. Fig. 5 is a perspective view of the air-conduit and of the drip-pan, shown detached and slightly apart from each other. Fig. 6. is a perspective view of the box for supporting the burner, and Fig. 7 is a rear view of the entire burner.
Referring to the drawings, 1 represents an oil-supply pipe controlled by a suitable cock 2 and a needle-valve 3. Connected with said pipe is a discharge-pipe 4:, having a nozzle 5. The oil is to be discharged under pressure, preferably water-pressure, and issues in a solid needle-like stream, as shown at 6, impinging against the rear thickened sloping wall 7 of an elbow or vaporizer 8. The effect of the impact of the oil against said wall is to spread the same, and said elbow being heated by means to be presently described the oil is vaporized and burned, the air for its combustion being admitted through the airpipe 9, surrounding the discharge-tube. The rear end of said air-pipe rests on a lug 10, cast upon the upper side of a box 11, and the front end of the pipe rests upon a lug 12, ex-
tending forwardly and then upwardly from the front wall of the elbow-support 13. Said elbow-support has its front wall placed in contact with the end of the box 11, and in the upper portion of said front wall is cut a recess 14 to receive the neck 15 of the elbow, said elbow being enlarged in front of said neck to form a shoulder 16, which shoulder abuts against the front wall of the support and prevents accidental rearward displacement of the elbow. The front end of the elbow is then carried forward at the top to rest upon the end of the air-pipe 9. Wings 17 are also provided at the sides of the elbow, resting upon the upper edges of the side walls 18 of the support. Said elbow is provided slightly below the point of impact of the stream of oil with a slot 19, the
function of which is partly to admit air for combustion and partly to permit a portion of the oil discharged upon the elbow to drip and fall through into a heating-pan 20. Said pan rests upon the extended floor of the support 13 and is formed at its front side with a high wall 21, which is connected by bolts 22 to a similar wall 23, cast upon the end of the airconduit 24:. Said air-conduit is made larger at the inlet than at the outlet end, as shown, to conform to the increase of velocity of the air as it approaches the heating-pan. The heating-pan is passed through an opening 25 in the front wall of the support and is readily slid into and out of position by means of the air-conduit, to which it is attached, as already stated. Said air-conduit has a foot 26, which rests upon the bottom of the box 11 and raises the entrance end of the conduit. however, the fire be extinguished for any reason while the oil was flowing, so that the oil continued to be discharged into the elbow for a considerable period of time without being burned, the oil therefore dripping into the heating-pan, the entrance end of the air-conduit is sufiiciently low to cause the oil falling into the dripping-pan to flow rearwardly through said air-conduit rather than over the walls of the conduit. Serious accidents have occurred by reason of the oil being left to flow all night for the purpose of heating, it being supposed that combustion was taking place, whereas in reality the fire had accidentally become extinguished, the result being that the oil would flood the furnace, and then on a careless attendent lighting the fire in the morning the oil in the furnace would be ignited with explosive violence. With the present construction this cannot occur, for the oil will flow backward to the front of the furnace, where it will be immediately noticed by the attendant on proceeding to light the fire and where its ignition in any case would not be so dangerous.
The box and elbow-support are cemented into fire-clay, as shown at 30, since these parts not being subject to great heat do not require to be renewed. However, should the elbowsupport itself be destroyed by the fire the elbow would still rest upon the walls of the fireclay, as shown in Fig. 7. The other parts are readily removable. T o replace the drip-pan, all that is necessary is to withdraw it by means of the air-chamber through the box and substitute a new drip-pan, which is the work of a second. The elbow can in like manner be quickly removed and replaced by a new one without materially reducing the heat by merely lifting the elbow out with a pair of tongs and replacing it with a new elbow. It is thus seen that I have provided a liquidfuel burner in which the parts subject to deterioration by heat are removable and replaceable with the least possible time and trouble. It will also be observed that the construc- Should,
tion is such that the rear side of the elbow can readily be cut out for the purpose of cleaning or removing deposits, also that there is a free current for the products of combustion around the elbow, so that the fire thereunder is not in any way checked.
