OIL-BURNER.

SPECIFICATION forming part of Letters Patent No. 453,35*?, dated J' une-2, 1891.

Application filed March 19,1889. Serial No. 303,896. (No model.) Patented in England January 14, 1887, No. 610.

A.To all whom it may concern,.-

Be it known that I, J AMES LYLE, a subject of the Queen of Great Britain and Ireland, and aresident of Paisley, Renfrewshire, Scotland, have invented certain Improved Appliances for Burning Oils, (for which a patent has been obtained in Great Britain, No. 610, dated January 14, 1887,) of which the follow- 1n g 1s a specification.

This invention consists of improvements in the construction of burners or jet-nozzles for the burning of mineral or other oils for lighting and heating purposes, and in which either compressed air or a steam-j et is made to unite and burn with theoil-jet in or at the point of these improved-nozzle burners, so as to cause perfect combustion.

In the accompanying drawings, Figures l and 2 show a sectional elevation and a sectional plan, the plan being taken on the'line l 1 of Fig. l, respectively, of my burner and its ttings for lighting purposes. Figs. 3 and et show a Vertical section and half-sectional plan, respectively, at right angles to each other, of a horizontal arrangement of burner and itsl fittings, as more particularly suited and designed for-heating purposes and blowing the llame into furnaces. Fig. 5 shows a detached side elevation of the annular oil and air burner and internal regulating and cleaning spindle.

The burner shown in Figs. l and 2 consists of the hollow cylindrical oil-tube A A', concentrically within an outer air or steam chamber and nozzle B B', both preferably with screwed neck and stop-joint collars at their lower ends for being secured into their correspondinglyscrewed sockets. The central tube is screwed into the inner end of its lateral oil-supply branch A3while the outer tube B B is screwed into the socket B2 of its valved air-supply branch B3, so as to lead t-he supply of compressed air or steam (whichever is used) up the annular space b between the central tube A A and the outer tube B.

The upper part of the inner tube A is made with a'ring of holes a to emit a thin circular stream of oil out into a narrow annular space b, formed all round the outer circumference of the inner perforated nozzle A and the inner circumference of the contracted upper end B of the outer air-tube B. By this a hollow spray jet of oil and air or oil and vsuperheated steam (when that is used instead of the air) is produced, to be ignited and burned beyond the burner A B as indicated by the dotted dame-line a'.

The annular oil-nozzle A A is left open at the upper end, and has a regulating and cleaning spindle e, with a piston c at one end and a handle e3 at the other, this spindle being screwed at e in a stuffing-box socket A2. The piston e at the upper end, which fills the burner A A, occupies a position above the ring of oil-holes a in the burner-nozzle, so that when this spindle e c is screwed up or down it regulates the openings in the holes for the emission of the oil, and it also cleans out the oil-nozzle A A, its body part e being small enough in diameter to allow the oil to pass up to, the burner from the socket and branch A3.

The coupling branches D and C are connected to the oil-supply AB and the air-supply B3, respectively, of the burner by the screwcoupling parts D3 and C3, which latter are either made polygonal or are provided with cross-arms d cl3, respectively, for tightening up these parts.

Referring tol Figs. 3 and 4, this shows a simple arrangement of the burner A A and B B as mounted horizontally in the sockets A2 B2 of its oil and air branches A3 B3, which latter B3 carries the whole on the couplingbranch C', with jointing-nuts at C, of the air or steam pipe. (Not shown in these figures.) [n this construction there is a short projecting annular rim at b2, forming a continuation of the stein B beyond the burner B for protecting the annular flame-jet 2, formed at the nozzle b. Otherwise this is substantially the same as shown in Figs. l and 2, and it is lettered to correspond.
