ATTORNEY Patented Jan. 6, 1931 HERMAN G. ,KLTNE, OF SPRINGFIELD, MASSACHUSETTS nusr connection Application filed July 29,

This invention relates to a dust collector,

" the general object of the invention being to provide a casing having an inlet at its, lower end and its upper end connected with the exhaustof a fan, with means within the easing for-separating the dust from the air passing through the same. Another object of the invention is to provide means for spraying water or other liquid in the casing, with a tank at the lower end'of the casing for receiving this liquid and'the dirt collected thereby. r 1 This invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to

be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claim.

In describing my invention in detail, reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which I V Figure 1 is a sectional View through one form of the invention. v.

Figure 2 is a plan view thereof. Figure 3 is a section on line 3-3 of Figure 1.

Figure 4 is an enlarged sectional view 1 through another form of the invention.

Figure 5 isa section on line 5-5 of F igure4. e 1 Inthese draw1ngs,A1nd1catesacasingwhlch is formed of a central portion 1 and two end" 35. portions 2 and 3, the portions being fastened together by bolts or the like passing through flanges 4 at the ends of the portions or sections. The lower section 2 is provided with,

an inlet 5 and the upper end of the upper section is connected by a pipe 6 with the inlet of a fan 7 the shaft of which is shown at 8 and the exhaust at 9 so that air will be drawn through the inlet 5,through the casing into the fan. Trays lO'are placed in the central section, these trays being; composed ,of bars spaced apart and'each tray supports a :body, 12 of coke or other porous material. Spray pipes 15 are arranged in the central section above the body of coke and these pipes are adapted to be connected with a suitable in cross section.

source of Wat'er'or other liquid so that the coke will be sprayed and thus the air passmg through the coke will be freed from the the dust therein. One of the spray pipes13 is arranged below the-bottom tray for spraying the air as it enters the casing. Above each 2 tray the casingis provided with a chute 14' bywhich the coke can be placed on the tray "and the chutes are provided with down- -wardly lnclined walls so that the coke will gravitate to the trays. A tank 15 isarranged underthecasing and this tank is adapted to contain water or other liquid and the casing is provided with a tapered bottom- 15 a discharge tube 16 which eXten dstF" into'the water in the tank15, so that the water from the spray pipes will pass'into the'casing 15 and carry with it the dirt collected 7 from the air passing through the casing. The 1 tanl': is provided witha discharge 17.

Figures 1, 2 and 3 show the casing formed of wood and of rectangular shape in cross section, while Figures 4 and 5 show the casing A formed of metal and of circular shape .75 From the foregoing it will be seen that that air will be drawn through the inlet, and

:this air will pass through the casing and through the coke supported on the trays thereof and will pass into the fan casing and be discharged therefrom free of dust, and the water sprayed on the coke will take all dust from the air as it passes from the casing. This invention will not only act to separate dust from air, but will also free the air from acid fumes, such as are known to exist in dust in asphalt plants.

The'improved' dust collector will collect dust which is lighter than the air. The col-- lector can-be built very economically and is strong and simple construction. There are no moving partsand,.therefore, no parts to wear out and they require no attention.

As no dust passes through the exhaust fax 1,1195;

fire and explosion hazards are reduced and the collector workswith safety in factories the working men.

The exhaust fan may, if desired, discharge the free-fro m-dust air back to the room from where it is taken, thereby eliminating or drawing out the warm air from the room in cool weather and bringing better working conditions for working men in warm weather.

" It is thought from the foregoing description that the advantages and novel features of my invention will be readily apparent.

I desire it to be understood that I may make changes in the-constructionand in the combination and arrangement of the several parts, provided that such changes 'fall within the scope of the appended claim.

What I claim is 1-- i A dust collector comprising a vertically disposed casing including a central section and end sections secured together, said end sections having tapered portions, an air outlet pipe connected to the tapered portion of the upper end section, a fan in the outlet pipe, an airinletmeans laterally connected with the tapered portion of the lower end section, a tank below the tapered portion of the lowerend section andalignedwith the casing, said tank being in communication with the last mentioned tapered portion, superposed filtering material receiving trays in the casing, sprinkling means above the mate- 3o rial on said trays and below the lowermost tray respectively whereby the air is mois- 'tened before and after passingcthrough the material, and dischargemeans for said tank;

- i In testimony whereofI afilx my signature.
