Abstract: 19,881. Crosbie, S. Aug. 31. Spray burners; vaporizing-apparatus; oilsupply fittings; burners, mounting and adjusting.-Apparatus for use with oil-fired metaltreating, marine or other furnaces, in which the fuel is atomized by a revolving atomizer, vaporized, and simultaneously mixed with air in any desired proportions, comprises devices operatively connected and driven from a single source of power for effecting the feed of oil and air with a simultaneous mechanical atomizing, carburetting, and vaporizing of the oil-fuel. Means are provided for varying the height of the apparatus, for altering the direction of the issuing vapour, and for rotating the carburetting-tubes. and the apparatus may be mounted on wheels. In the apparatus shown, one or more carburetting-tubes H are arranged within a chamber E which is provided with chimneys F', F<2>, lined with fire-bricks, ganister, mixtures of magnesium, limestone, and carbon, &c., or filled with cored refractory balls, and may be lagged with infusorial earth, slag-wool, &c. The tubes H open into an air-box I supplied from a fan M through bellows O, and within each is an oil-supplying pipe S provided with cones S' similar to those described in Specifications 8765/12 and 18,917/12, [both in Class 69 (iii), Spray-producers &c.] and having sharp cutting-edges upon their faces or ends. Stuffing-boxes R receive the outer ends of the pipes S, which are rotated upon ball bearings at high speed through gearing by a shaft g, driven by a belt or chain n, from the fan shaft, and oil is supplied to the pipes through regulators P, pipes i, and the boxes R by pumps Q, which are actuated by gearing through a countershaft from the shaft g. The spray in the tubes H is vaporized by a burner N, the oil-supply to which, according to the Provisional Specification, may be regulated by an expansion-pyrometer in the chamber E, which actuates the oil-supply valve directly or by closing the circuit of an electric motor connected to the valve. An iris diaphragm actuated by a worm-wheel Z controls the air supply and is operated by variable gearing from one of the oil-supply regulators P as described in Specification 25,410/11, [Class 135, Valves &c.]. Glands e, and. if necessary, ball bearings, are provided on the tubes H to permit of their being rotated by worm gearing T. Verticallyadjustable bearings J are provided on the wheeled carriage K for raising and lowering the apparatus, and a screw fitting U for elevating or depressing the furnace end of the apparatus. The fan M and the electric motor, steam-engine or internal-combustion engine driving it may be mounted on a separate carriage. Alternatively, the air-fan shaft may be driven by belts, chains, or gearing from another shaft. When used with marine boilers, the device may be carried on sliding blocks. In modifications, the air-fans are keyed upon the oil-pipes S, or they may be carried each by torsion rods on sleeves rotatably mounted on the oil-pipes, as described in Specification 498/12, the sleeves being turned by the prime-mover through gearing. In these arrangements, the cones S<1> may be dispensed with.
