is a similar View showing a different modified construction embodying my invention.

Throughout the drawings like numerals of reference refer always to like parts.

In general my machine comprising essentially a casing comprising a conical base or bottom structure having a dust outlet therein, a head structure having an air outlet in its deck, and an sir-directing structure within the head of the casing into which opens, approximately tangentially, an air inlet, the air directing structure being ranged to direct air into a vertical whirl therein in an area into which the air-escape outlet opens, preferably at a point contigw ous to the periphery of the whirl, and said air directing structure being provided with openings therein communicating with spaces witl'xin the casing exterior to the said vortical whirl urea.

In the specific embodiment of my invention illustrated in Figs. 1 and 9, indicates the conicni bottom of the casing provided with the usual dust outlet 11 at the bottom 2, the side walls 12- thereof being disposed to form chords of the circle outlined by the top of the conical bottom 11, so that the area within the head is substantially a square inscribed within the circle formed by tho top of the cone 10.

To etic'ct the closure of the portion of the top of the cone lying without the area of the head 12, a deck 14. is provided for the top of the cone 10, whereon the wells 12 of the head ere built, the deck 14 having on opening therein substantially coextensive with the plan area of the head 12.

15 indicates the deck of the head 12, having therein an air outlet 16.

Within the head of the casing, extending downward from the deck thereof is an" airdirecting structure generally indicated 'at 17, and composed of a plurality oi? plates 18, generally disposed to encompass '9; vertical whirl area and indirect the air in Whirl therein into operative proxi'mityto the air outlet 16, that it may freely escape therefrom.

19 indicatcsopenings between the plate 18 establishing communication" between the vorticsi wl'iirl. 20 encompassed bf the aii-directing structure 17 and the exteiior air-space 21, intermediate said air-directing structure and the casing. c

21 indicates the angular spaces at the cor- -ners of the casing wherein eddies: form by reason of the shape of the casing.

22-22 indicates eddy-forming means in the corners of space 21, said means being shown as rods grouped in the corners and depending from the deck. 23 is an air inlet opening:tangentially into the air-deflecting structure 17, the inlet spout being closed at sides and bottom, to the end 23 of the spout, where com mences the deflector structure 17, the plates or sections 18 whereof extend in a generally circular form, each plate being preferably laterally out of register with the adjoining plates, with its outer end at a slightly n greater radial distance from the center of fthe casing than the proximate end of the plate in advance thereof, so that the spaces 19 may be said to be tangential openings. Preferably the plates 18 are secured in any 5 suitable manner to the deck at their rear ends (with reference to the direction of air this end I provide the'bolts- 24 secured to the free ends of the plates 18, and taking through the casing walls 12", said bolts being provided with, the winged adjusting ;5 nuts 25. From its point of juncture with the wall of casing 12, the air-deflecting structure extends in a suitable curve, preferably terminating in a relatively short curve17', to some point contiguous to the 40 air escape outlet, the arrangement of the deflecting structure being such as to permit the formation of a vertical whirl Within the area included therein, such vertical whirl being eccentric to the axis of the casing. The space 21 without the whirl area aforesaid is preferably such as to permit air therein to flow in a path concentric with the casing axis except where interrupted by the inlet spout 23, the rectangular shape of the casing providing at the corners angular enlargements of the circle of air flow, IS-ShOWD at 21 which constitute eddy spaces. The openings 19 a-lt'ording communication between the air-flow space and the whirl area Within the directing structure 17 are preferably arranged to direct the air into the air flow space at the points of closest pr: ximity of the directing structure in the casing wall 12. At the point where the directing wall structure approaches the end of the inlet spout 22 there is preferably left a space 26,

in which is preferably arranged a regulating plate 27 disposed at an angle and adjustable vertically.- For simplicity the plate 27 may be passed through a suitable slot cut inthe deck of the casing, and held therei'n'by frictionalcontact with the balls of the slot, adjustment being efi'ectcd by withdrawing the strip partially from or introducing it farther into the interior of the casing. q 4

Below the air-directing structure 17 within the casing, I preferably provide the inverted conical guard 28, preferably of less diameter than the interior diameter of the' square head, open at top'28 and bottom i 2.8, and suitably supported axially of the casing as by the arms 29-29 fastened to the deck 141- of the cone 10. V

28 indicates a skimming opening in the guard 28,'but any number of such openings may be provided, two being shown.

I also prefer that the outlet 16 be universally adjustable as to position, and to this end I form in the deck 15 of the casing,

a concentric aperture 80, wherein is mounted a for rotation an eccentric ring member 31,

having therein an eccentric aperture 32,

within which, in turn, is disposed for rotation the inner eccentric member 33 in which The action of the machine as shown above wall the air is brought into operative proximity or the air escape outlet 16 through which it freely escapes. ent'that in its rotatlve and whirling movements the dust carried by the air, by reason the out-let 16 is ecccntrically formed.- Itv will be apparent that by suitable adjustmenti of the double eccentric structure the posi- It will be appari of its greater persistence of motion than air,

masses against the directing structure, and at each of the outlets 19 accordinglya portion of the dust is projected into the exterior air-flow spacc 21. In said spa e 21 tjhere is set up an air-flow dominated by the whirl within the directing wall 20, said air-flow being generally in. like direction with the direction of rotation with said whirl. The dust carried by said air, in rotative flow, is centrifugally thrown outward, and'tends to collect in the eddies 21 from which it falls centric in the casing to concentric in the base t-ically purified or freed from dust, and the air escaping into the air-flow space 21 is heavily dust laden.

The air whirl in the head of the casing above described causes to be formed in the chambe therebelow an air Whirl substan-- tially concentric With the casing axis, the guard 28 forming a sort of conical bottom for the upper eccentric Whirlarea, and prcventing the distortion to any marked degree of the whirl Within the conical bottom 10 of the casing under the domination of the vertical whirl. in the head.

The distortion of the whirl axis from ectends to prevent the formation of such a rarefied condition in longitudinal alinement With the dust outlet as would tend to prevent free delivery of the dust or to cause light dust particles to ascend into the upper chamber after once being discharged there from.

In each oi the eddies 21 the tendency of the air seems in practice to be to force its Way downward, and adjacent the inlet the deflector 2T positively forces the dust laden air downward, so that the space below the deck 14 of the conical bottom is constantly receiving :t'rcsh increments of air, which prevents the accumulation at such points. of dust masses, and I find in practice that the machine maintains itself clear of acvcuinulated dust at such points. The dust thus dropping with the air from the eddy spaces 21' into the conical bottom 10 of the casing, descends spirally therein under the influence of the substantially concentric vortical whirl to the outlet 11 where it is discharged. Thus it will be seen that I provide a machine wherein the dust-laden air is caused to travel in a curved path from which open the tangential skimming-open lugs 19, of adjustable Width, which serve to permit the passage there past oi all of the massed dust before the end of the directing.structure is reached, while a large portion of the air is projected at relatively high velocity into operative proximity to the air escape outlet 16 through which it freely escapes, and all the dust, forced into the air-lion" space without the vorical Whirl area, escapes trom the eddy spaces or elsewhere, into the conical bottom of the ma chine, where, under the influence of the centrifugal ,vortical whirl, it descends to the dust escape outlet.

ln l have shown a modifiedconstruction wherein the inlet 23' opens angularly into the casing 12, though tangentially to the air-directing wall, and is provided with a side piece 23' pivoted to form a valve, movable by the adjustment of" nut 23, threaded on the bolt :23 extending from the valve through the inlet wall, to vary the size of the opening between the inner and ill of the inlet spout and the aindetlecting structure 17.

*In Fig. 5, a modified embodiment of my invention is shown wherein the casing is circular, the air-flow space 21 being correspondingly approximately annular. The eddy creating means in such construction may comprise blocks or strips 22 set vertically in the space 21 to form obstructions therein.

While I have herein described in some detailspccilic embodiments of my invention it will be apparent that numerous'changcs might be made in the-specific--construction without departure from the spirit and scope of my invention.
