Specification of Letters Patent.

Patented Dec. .8, 1914.

Application filed August 1, 1913. Serial No. 782,434.

To all whom it may concern:

Be it known t at I, SYDNEY Cnosam, a subject of the King of Great Britain, residing in New Barnet, England, (whose post-ofiice address is The Chestnuts, New Barnet, in the county of Herts, England,) have invented certain new and useful Improvements in or Connected with Apparatus for Vaporizing Oil, of which the following is a specification.

This invention relates to apparatus used in conjunction with oil fuel furnaces, for

the atomizing and vaporization of the fuel simultaneously with its mixture with air which apparatus is of the kind wherein the liquid fuel is atomized by means of a re volving atomizing device and \an intimate mixture of the air and oil, in any desired proportions, is obtained prior'to its injection into a furnace for complete combu'stion therein. 7

It consists in'i rovements according to or effecting the mechanical atomizing, simultaneously with the carbureting and va for. providing the eed of oil and for supplying the air to the atomizing device are operatively connected and driven from a single source of power, while means are provided for varying the height of the longitudinal axis of the apparatus, for altering the direction of the vaporized oil issuing from the delivering end of the apparatus and for periodically rotating the carbureting tubes employed.

The improved apparatus may be mounted onwheels to be of a portable nature.

The invention will be described with reference to the accompanying diagrammatic drawings, in which- Figurel is a side elevation of an apparatus constructed according to this invention; Fig. 2 is an elevation of the reverse side of the ap aratus; Fig. 3 is a furnace end view of t e apparatus; Fig. 4 is the front view of the apparatus; Fig. 5 is a artial section through A-B marked on Figs. 1 and 2; Fig. 6 shows a part of the apparatus in section through CD on Fig. 3; and Fig. 7 is a sectional detail of a conical atomizing device.

An oil vaporizing apparatus constructed according to my invention comprises a -chamber E of suitable shape and of cast iron, wrought iron, mild steel, or other suitable metal. Within the chamber is' arorizing of the oil and ranged one or more pipes H for a purpose hereinafter referred to; This chamber is lined within by fire bricks, ganister, mixtures of magnesium lime stone and carbon, or other refractory substances, to prevent the radiation of heat andincidentally the gradual oxidation of the metal case. The chamber may be further protected on the exterior by a layer of non-conducting material such as infusorial earth, slag wool, or other good non-conducting materials, covered in and held in position by sheets of charcoal iron, the object of which is also to prevent radiation of heat.

,Upon the front end of the apparatus is bolted an air box I of suitable form. To the bottom of this air box is attached an .iris diaphragm air regulator which directs the incoming air always axially, that is to say centrally; to this iris diaphragm is attached outside the air box a worm wheel Z adapted to be actuated by a worm upon a shaft 2 to which mechanical movement is communicated from the shaft of an oil-inlet regulator to be subsequently described. The pipe upon which this worm wheel is fixed has upon it a bellows O fitted with a slipping fit so that the worm Wheel may be revolved without revolving the bellows below it, the bellows is made of leather or other suitable material, and is connected to the fan M for shape for instance circular as shown, are I the two pipes H into which the air is blown by fan M. The pipes H are attached to the ends'of chamber E in glands e in such a manner that they may be rotated in those ends, ball bearings being provided if neces-v sary. Into each of these pipes H is passed a small pipe S for conveying the oil to be atomized and upon the ends of these small pipes and within the larger pipes H are cones S furnished upon their extreme faces or ends with sharp cutting edges as shown in Fig. 7 Alternatively these cones may be similar to those described in my British specification No. 18917 of 1912 and in my co-pending nited States patent applica-' tion Serial No. 7 58515 filed April 29, 1913.

The cone carrying 'pipes' S pass through the outer wall of the air box I to its exterior and enter chambers R which serve as stufiing boxes. At right angles to the pipes S is a ranged so that the flames may 7 burner flame may be shaft 9 carried by bearings constituted by The oilvis passed into the chambers R by flexible tubes 2', the oilvbeing aspirated by' pumps Q through oil regulators P and forced into the chambers, thence through the pipes S which are adapted to be turned upon ball bearings at high speed.

By reason of the high speed at which these pipes turn, the oil when it reaches the edge of a cone is cut to ieces and thrown out into the'larger pipe where it is mixed with the air therein and becomes in physical appearance like a white fogand, assisted by the heat from the flame be projected into the chamber E, is vaporized. I The regulated by any suitable means.

The flame acting on the exterior of the two pipes in which the cones are revolving causes the vaporization of the oil, While the carboninonoxid and othergases are projected with a whirling motion into the furnace Where they take up sutiicient oxygen to produce complete combustion of the fuel.

The large chamber E is provided with short chimneys F F to allow the surplus heat to pass oii and to provide a current of air for the burner.

The oil and air regulator, which is the subject of my British specification No. 254510 of 1911 and is fully described therein is preferably used in apparatus constructed 3 0 cording to the present invention, for the purpose of delivering the oil and air through the respective devices in such a way that the turning of the handle upon the oil regulator fitted with suitable transmission gear will cause the delivery H in the chamber E, constituting a carbureter, the proper proportion of air that is required to combine with the oil, and the gears may be changed according to whether it is desired to produce a 'reduclng flame or an oxidizing flame in the furnace, and may be of any ratio.

The chamber E and the associated parts are carried by a frame or carriage K provided with wheels L, L of any convenientsize. On the frame K are bearings J which can be adjusted as to height by means of the screw device J, so that the height of the axis of the chamber E can be varied. At the furnaceend of the frame is arranged a suitable screw raising or lowering device U which can be-operated to lift or lower the furnace end of chamber E turning about the bearing J. By operating the device J,

the chamber E and associated parts may be of a burner N ar- "turned by a capstan wheel T to the pipes bodily raised or lowered, and by Working device U the discharge end of the chamber may be brought into registration with the part of the furnace with which it is to cooperate.

The pivoting or tilting features of the apparatus are very useful, for the reason that they permit the combined gases to be injected into a furnace or combustion chamher, with which the apparatus is to coiiperate, at any desired height, andeither downward upon any metal under treatment, or upward in the case of furnaces of a certain construction The mechanism of my apparatus may be driven in any suitable manner as for instance by electricity as illustrated in the drawings, but in any case, whatever the motor. the air fan only is driven by it, the power required for the other parts of the mechanism being taken from the extended shaft m of-the fan, @fi this shaft is carried a chain or belt a to a wheel V on the shaft g. The fan M and the prime mover, such as'motor a, may be mounted on a separate carriage M. connected or coupled in suitable manner to the frame K. Upon shaft 9' are keyed wheels-W connected by belts or chains vto gears X on counter-shafts operatively connected to wheels Y which in turn communicate their motion to the pumps (,2 aspirating the oil through the oil regulators P and delivering it under pres-' sure to the stufiing boxes lit.

v The pipes H passing through the cham-=' ber E and in which the oil is atomized as it leaves the cones, have each fixed upon them, by set pins or keys, a worm wheel Tactu ated by a 'worm. T on a shaft T which is I By these means the pipes may be? periodically turned through any desired angle, the object of this being to present a new surface to the heat in order to give the pipes a longer life than what they wbuld have if the necessary heat were allowed to impinge on the samesurface of the pipe always: the burning through of the pipes is thus delayed.

In the furnace associated with the apparatus of this invention the atomizedmim ture is completely burnt to :CO which passes out of the uptake into the atmosphere. I

For firing boilers on board ships, the ap paratus may be carried upon either low wheels or the wheels may be omitted in order to accommodate itself to the openings of the fire boxes in cases the chamber E-"is preferably made smaller in diameter and contains only one vaporizer or atomizing tube. For marine purposes it is not necessary for the fans t0- be attached to the frame-of the apparatus for they may be placed in any convenient position. v
