Application filed Filly 53, 19%.

To all whom it may em'wew Be it known tllai 1, CHARLES J. Elm-C4, :1 citizen of the United States, resiciing a5 Chisego, in the county cf Cool; and State of Illinois, have ii'iventefl certain new useful Improvements in Oil-Furnaces, 055 which the following is e specification.

This invention relates to ail fui'mzees has for its primary object t0 mvifle i.

combinetien 311 5; in rengement of par 5 in an oil furnace.

One of the objects 0f the presei'ii tion is to provide improved mean." 3'0 ing oil to an oil consuming furilece.

A more particular object is L0 previ le an improve-Ll construction, cembinaiion end an rangement of parts in the lire Chamber 0:? an oil furnace "for the purpose seci'u'ing the 131 best degree of combustion (if feel.

t'ance of the burner plate 6. lYitlrlu the tube 1.5 is provided a spiral guide-Way for the oil m' the form ot a Wire 16 Wound on :1 helix whose diameter as it nears the bottom of the tube '15 decreases, as shown at 1'7. until finally the lowermost end of the wire us sumes'the form of a needle 18 disposed immedietely above .a well 19 formed at the center ofthe burner disk 6. In order to pro- I ride a shield for the oil tube 15 to protect it against the heat in the combustion chamber and thereby prevent a premature ignition an outer tube 20 is concentrically mounted with. the tube 15 and extends below the tube- 15 to a point adjacent the burnerdisk 6.

. The upp r end of the outer tube 20 is pro vided with whereby it is adapted to be suspended Iron the threaded cylindrical "Wall 01:21. cap en? mixer 26 through which sir is admitted into the outer tube 20 by means of openings 21 provided in the casting 26. i

As shown in F 1 the depending oil tube 15 connected by serewftbreads with the casting 2% while a horizontalservice'pipe which conveys oil directly from the lower hes-ting system Work through contracted end of an. oil reservoir 24: is coupleddirectly to a tubular projection on the casting 26 which leeds'to theoil tube 15* Avulve Q serv' to regulate the flow of the oil from the reservoir Adjacent the upper end. of the oil tube 15., a barrier or hurdie 20 is provided b fihe tubular projection of the cup 2%; to d the flow capacity of l l I i I l y l I the pipe sulilcu: tiy to insure the. oil lee-- coming thoroughly "warmed and mobile before it enters the depending tube In ordcrito provide means for keeping the 'oil in the reservoir mobile, a circuit tor conveying a beat om the furnace to said reservoir is providedln form of u pipe 2'2", which wipe connects up with a coil 28 extending und the dome within the air space or furnace. /Vithin the oil. reservoir El -i is second coil pipe whereby the medium is adopted to give up its heat to the oil. In the preseub embodiment; the oil is adapted to perform its the agency er Water, for which purpose branch pipe 30 from :1 water main, or other suitable source of supplyycounects with the pipe 27.

In'order to provide means for starting ihe burner when the furnace is cold the receptoole is provided with en upertured boss 38 Within which is udjustably mounted by queens of screw threzuls, e burner tube 36 buying suuir mixer 37" slidubly en eeolses understood and as follows: The valve having been opened to the proper degree, the 01] is admitted to the :lmvmvurdly depending oil tube wherein it strikes the spiral guide 1.6 whereby a whirling motion Will be imparted to the oil. As the oil approaches the lower end of the tube 15, it passes over the contracted portion 17 out ontothe needle l8 and drops into the well 19 from which it feeds around the spiral 9 and through the perforations 8, in the manner already indicated. Inasmuch as the plate 7 has already been heated to the necessary degree of heat by the burner 36, the oil is vuporized into a, gas which expands and fills the upper end of the combustion chamber end dome 10 The upper end of the combustion chamber and dome-being entirely uir tight, a closed reservoir tor gas is formediwluch burns in and around the uptakes l3 and bottom Wall or the chamber- 11. By reason of the draft up the chimney, air is drawn in through the openingsQl in the cap 26 and passes down the outer tube into the combustion chainher and mixes With the gas formed therein. The air thus drawnin will be distributed radially in all direct-ions over the burner,

plate 6 where some of it mixes with the gas formed from the oil. and the remainder passes upwardly over the edges of the recep-- tucle and thence through. the uptakes 18, wherein the combustion of any unconsumed gases continues. Such'continued combustiou also takes place within the chamber 11, being facilitated by having the wells of the upm res 13 and chamber 11 exposed directly ,to the heubwithin the combustion chembeui A secondary combustion is thus provided,

which, by reason of the construction and combination of parts, shown best in Fig. 1, takes place a a higher temperature than that existing all the burner plate. This de-- vice is peculiarly serviceable in cases Where an over feed of oil takbs place, in which in stance unconsumed pymgeuous disiillates cob lecf; within the uptake tubes 13 and in some degree within the chamber 11. These distilletes are therefore. not. Wasted but are made to undergo combustion which. does not take place at the temperature existing within the combustion chamber,
