ATOMIZER FOR LIQUIDS.

Application filed August 15, 1923. Serial No. 657,532

To all whom it may concern:

Be it known that I, GHARLEs LINKii, residing at Paris, France, a citizen of the French Republic, have invented or discovered certain new and useful Improvements in Atomizers for Liquids, of which improvements the following is a specification.

My invention relates to improvements in atomizers for liquids, and particularly to atomizers whose essential feature is a member rotating at high speed. I have applied my invention in the construction ofburners for the consumption of liquid fuel and in that application I shall describe it. But

the applicability of the invention in a Wider field of utility will be recognized.

Inthe accompanying drawings Fig. I is a fragmentary view of an actual assembly, showing partly in axial section and partly in elevationl the structure in which my in- Fig. II is a view of the same structure in side elevation. Fig. III shows in two fragmentary views, in section and in elevation, a detail of structure. Fig.

.IV is a View in Side elevation of the assembled burner in one form. Fig. V- is a view of it in another form, and illus-,

disk is provided on either side witha plate of suitable thickness, whose edges are folded back in such manner as to form a circular canal. fices the number of which may be varied. These orifices in cross-section are not uniform through the plate, from side to side; but they flare, enlarging in diameter as they approach the disk, in 'such manner as to form openings in the shape of a truncated cone, or approximately such, the large'base of the frustum being toward the disk.

Above each of the so-formed openings, a small plate is arranged in any suitable manner. It may, for example, be formed of metal and soldered aldng one edge to the larger plate, and along its opposite edge pressed against the disk.

The operation of mechanical dissociation begun in the circular canal is continued in From this canal lead ori-' these openings. The very slender jet of liquid strikes forcibly'upon the small plate and is broken into very fine particles. These escape on either side and spread upon the disk, and there the operation of subdivision or atomization is completed.

The liquid to be atomized flows from each of the cups across an annular slit several millimeters in extent, formed on one side by a sort of crown whose rim is oblique to the axis of rotation, and on the other side by a circular slab, the edges of which have the same obliquity as the rim of the crown. The two slabs by suitable means of assembly hold the plates secure, and all these parts rotate in unison with the disk.

Each cup, though closed, is provided in its side walls with orifices, to give passage to a ring which hangs within the casing, and into a pool of liquid within the casing.

By such means liquid, responsive to its disk, and it will sufice to remark that a system of speed reduction should then be interposed.

It is possible, by, way of variation, to provide a cup on oneside of the disk only. The liquid to be atomized will in that case gain access to the side of the disk which lacks acup, by means of openings pierced through the disk similar to and alternating in position 'with those formed in the plate which is arranged on the opposite side of the disk. These openings too will be covered over with small metal plates such as those already described, and their role will be precisely the same.

These improvements may be applied,

whenever a liquid is to be atomized, and the motive power requlred for their opera-- tion will not at all exceed that employed Plates 0, 0' are arranged upon opposite sides of the disk. Their margins are bent back in suitable manner, to form, as has been eX- plained above, a sort of circular canal d, (5. At the periphery of each of the plates 0, 0 and adjacent disk 6 the orifices e, e, 6, etc. are arranged; and to them, as has been explained, such form is given that the liquid delivered through these orifices under centrifugal force makes impact upon the small plates 37, p. The jet then is spread upon the disk 6 from each side of the little plate in the form of finely divided particles, and these spread fan-like over the disk as they approach its periphery.

Each of the plates 0, c is in this instance secured by a slab f, f. One of these slabs is formed in one piece with the hub which carries the disk, the other forms a companion piece, cooperating with the first in effecting assembly. Rivet-holes 9, g are formed in these slabs f, f, to receive rivets,

when these means are employed for securing the entire assembly.

The slabs f, f are circular and their edges are cut in such manner as to form an inclined plane, defining the circular slit through which the combustible liquid finds exit from the cup.

The cups h, 71. themselves which hold the liquid are suitably mounted upon the shaft, a. They terminate in a sort of crown, i, i, inclined to the axis of rotation in correspondence with the inclined edges of the slabs f, f, and in the assembly these inclined edges of the cups stand opposite the inclined edges of the slabs, and between slab and cup-rim a circular space or slit is formed of several millimeters extent, through which the combustible liquid escapes in order to reach the canal formed 'in each of the plates 0 and 0 and orifices e, e,

. opening from the canals.

- suitable number.

In Fig. III the minute configuration is indicated of the orifices e, 6, through which the combustible liquid when confined with in the circular canals d, J escapes to the surfaces of the disk. A part only of the plate, bent back as indicated at his shown in- Fig. III. The orifices are formed in They are formed at the periphery of the plate and at the base of the bent-back margin, and byvirtue of the shape given them, a shape indicated in Fig. III, the combustible liquid is projected in fan-like spread upon the disk.

GI'OOVBS m, m are formed in the hub. In these grooves rest rings 8, s. Resting in these grooves m, m, the rings 8, 8 depend into a pool of combustible liquid maintained in a suitable manner in the casing 9%, within which the disk turn's. In Fig. I therings s, s are shown in cross-section 1n their position in grooves m, m. In Fig.

-IV the position of these rings is indicated,

rotated. It is the axle a with its hub which is rotated. The orifices m, :20, indicated in Figure I are, as will be apparent, adequate to permit the passage therethrough of the rings 8, s, and to permit the functioning of these rings in the manner described.

It may be that, with safety in View, or to meet restrictions imposed, the reservoir of combustible liquid should be entirely separate from the casing in which the disk turns. In that case an arrangement such as that shown in Fig. V may be adopted. Here a reservoir of combustible fluid is'contained within a separate casing 10, and a chain 0, travels within a suitable duct to carry fluid from the reservoir to the casing a, within which the disk turns. The chain may of course be driven, as has been said, directly or indirectly from the shaft which carries the disk.

The more deeply the ring or chain is submerged the greater will be the, quantity of liquid conveyed to the cup, and any expedient within the knowledge of the engineer may be resorted to, in order to lower the surface into which the ring or chain plunges. 1

In the case of feeding by means of a chain, as particularly shown in Fig. V, a small tube It may be provided, to limit the height to which the liquid may rise within the casing 91.

I have said that instead of thebilateral arrangement shown in Fig. I, I may employ a single cup. This is particularly illustrated in Fig. VI. Here there is" a single cup h provided on one side of the disk only, and correspondingly, there is a single plate 0 provided on the sameside of the formed by the recurved edge of plate 0" to thefurther side of the disk I). Asis the case with the openings e, these openings 3 also are overhung with small plates 2. By such provision the liquid from one cupmay be spread upon both sides of the dlsk The invention which I now have described in its application to a liquid-fuel burner will be seen to be an improvement upon the apparatus described in my two pendlngapplications for Letters Patent of the United States, No. 468,318, filed May 10, 1921, and No. 547,424, filed May 28, 1922.

I claim as my invention:

1. In apparatus for atomizing liqu d the combination of a rotatable disk, a marglnally flanged plate concentrically mounted upon the disk and rotatable in unison with the disk, an opening piercing the plate at the base of its marginal flange and a deflector plate borne by said main plate and extending toward the surface of the disk and overhanging the said opening.

2. In apparatus for atomizing liquid the combination of a rotatable disk with thick hub portion and thin web portion, a cup mounted ooaxially with said disk, the rim of the cup being beveled and cooperating with the adjacent surface of the hub portion of the disk to form a passageway for liquid from the cup flarin outwardly and toward the thin web portion of the disk, means for gathering the liquid flowing under centrifugal force through said passageway and projecting it centrifugally in spreading jets upon the surface of the web portion of the disk, and means for supplying liquid to said cup.

In testimony whereof I have hereunto set my hand.
