.The present invention relatesto `gas separators, and aims to `provide i a novel andf improved gas separatingmeans particularly useful for incinerators for hilrning'arhage 5 and other refuse, this application .Qing a division ,of the application for patent on V1n- Lcinerators, led Oct. 7, 1925,!Serfal No. 60-

.9.6.0 (newV Patent No. 1,651,636, granted Dee. 6,1927);

It is the object of the irwentonY to provide novelV means for Separating from the ,gas Y'which is discharged to thejiltlllosphere, the unburned particles, such as Contained in smoke and green gases,`in Order to prevent the gases discharged into the? atmosphere from being obnoxious.V The unharmed material'or particles are arrested, thereby preventing excessive soot andV obnoxious Y gases :from passing intothe atmosphere,"making the incinerator available for use in 'localities which strictly require incinerators to burn without offensive smoke or smell.

Withthe foregoing andother 'objects in lview, whichwill he apparentes the deseri Y 25" tion proceeds, the` invention jre-Siders im e construction and. arrangement of parte, asi", through the centralportion .ofthe flueway -hereinafter described and claimed, itfbeing understood that changes oanhernadewithin the scope of whatis claimed, without de- A, 30 parting from the spirit rof theinvention.Y

, The invention is illustrated in ...Palylng' drawings, wherein-f y` .Flgnre l `illustrates.an incineration partly in side elevation and partly in vertical secthe aecomv13g; tion, including theimproved gas separator.

on which is disposed ltering material 90, which may be coke, cinders, soil, or other suitable material to arrest particles of soot, ashes and other solid material thatk enters the space 82.

The gases passing through the opening 76 from the furnace are separated, the valve or damper 78 being opened so that, in addition to the forced draft created by air discharged through the nozzle 54, there is a natural draft up the smoke stack 75. The flames and more complete products of combustion travel along the center of thestream,

as is well known, and pass through the center v of the flue-Way leading from the opening 7 6 to the opening 77, while the smoke and green f gases moving along the sides andtop of said flue-way'pass through the slots between the separators 79, 80 and 81 into the space 82. If the natural draft is sufficient then the damper -84 maybe opened so that the natural draft will draw the smoke and green gases upwardly through the beds or layers 90 of filtering material whichwill Varrest'the particles of soot and other solid matter. If the natural draft is not sufiicient for this purpose,'then the fan 87 Vis operatedvtocreate a forced draft up throughthe layers`90 of filtering material, and the filtered gasis discharged from either opening 83 or 85 into the smoke stack. In this way,smoke and green gases are eliminated, so that'the gasesdischarging from the smoke stack will not constitute a nuisance or be obnoxious. It will be noted that the flue-way is tapered or decreases in size'from the openingv76 tothe opening 77, thereby having a tendency to compress the gases flowing through said uexway', and the smoke and green gases remaining at the outside ofthe stream iwill be crowdedv Ythrought-heslots or openings between the separators 79, 80 and v81 into the space 82.` The draft extending through the space 82 will serve todraw'the smoke and green gases from the separating means, so .as `not to impair the flow kof gases from the furnace to the smoke stack, inasmuch as the gases flowing through thespace 82 pass into :the smoke stack through' the opening' 83 or to' through Ithe space 82 will assist in drawing the opening 85 and fan 87.' This draft the smoke and green gases from the vseparating means through the filtering material v90. The filtering beds yor layers 90 may beof any suitable area or extent necessary, preferably greater than the cross-sectional area of the smoke stack75, so as not to impair the draft, and the filtering material may be removed and replaced as voften as necessary. `The housing 74 has clean-out doors 91 in order that soot andgother accumulations may 'be removed. g

Figs; 4`a`nd 5 illustrate variation in the means forl removing the smoke and green gases from the products of'combustion for fromthe chamber of the housing 74.

The heads 108 are enclosed within the covers105 which alsov close the openings 101 The heads 103 are mount-ed for turning movement 'about vertic'alaxeaand supply pipes'lOA for steam, compressed air or other pressure uid are connected by swivel connections with the upper ends of the heads 108 and have control valves 107. The lower ends of thejheads 103 are geared, as at 108, to shafts 109 that have hand levers 110 which may be swung to turn the heads"103` and change the angular positions of theV nozzles 104. The housing 74 'has the space 82 in which the grates 89 are disposed to Asupport the filtering material, and a suction fan 87 is located between the 'space 82 and smoke stack 75', the comico-- tions of the space 82 with the smoke stack being the'same as shown in Fig. 1. c

The steam,'air or other fluid being Vdischarged under pressure from the nozzles 104 is directed obliquely across the stream ofl products of combustion passing through the passage 100, and the. streams of fluid from the nozzles passing through the openings 102 will intercept the particles of soot, thereby blowing the smoke and green gases through the openings 102 into the housing 74 so that the smoke and green gases will be filtered before passing through the smoke stack. yThe 'angular positions ofthe nozzles 104 may .be adjusted according to the velocity of vthe products 'of combustion in flowing through :the passage 100. It will be apparent that thefluidV discharged from the nozzles from one'side Vof the passage 100 will have a tendency to force the smoke and green gases toward the opposite side of the passage so as to pass readily through the openings 102, thereby separating such smoke and green vgases from the products of combustion which pass through stack- Y 1 Having thus described the invention, what 'isclaimed as new is j1. A gas separator comprisingafluewaydecreasing in size from its inlet to its outlet, a`

chamber at least partly surrounding said flueway, said flueway having a series, of openings between it and said chamber for the flow into said chamber of the products of combustion which move'alongthe outsideof the stream.`l l

the opening 77 intov the sinokepassing through said lueWay, and means for creating a vforced draft from said ueway through said openings and chamber.

2. A gas separator including a lueway, a chamber at least partly surrounding said flue- Way, said iiueway having a series of openings between its ends for the ilow into said chamber ofthe products of combustion which move along the outside of the stream vpassing `through said flueway, and means for creating avforced draft from said iueway'through said openings and chamber.

In testimony whereof I hereunto aiix my signature.
