Claim 1

A mixing device for gaseous fumes comprising: an elongated tubular housing comprising two telescopically interconnected parts and forming a torpedoshaped configuration, the free end of one of said interconnected parts defining an intake port and the free end of the other of said interconnected parts defining an outlet port, the interconnected parts defining therebetween within said housing a gaseous fume mixing chamber, a plurality of openings spacedly positioned around the periphery of one of said parts forming air inlet ports interconnecting atmospheric air with the interior of said chamber, a deflecting vane mounted within said one of said parts for swirling the gaseous fumes received through said intake port in said first part of said housing and discharging said swirling gases into said chamber, wherein the swirling gaseous fumes are aerated by air injected into said swirling gaseous fumes prior to discharge out of said outlet port, said mixing chamber having a bore diameter greater than the bore of the intake and outlet ports of said parts, the periphery of said mixing chamber tapering into the bore of said outlet port which together with said air inlet ports forms a venturi for further aerating said swirling gaseous fumes, and the free ends of each of said parts being tapered to form nozzles for receiving in slip-tight fitting arrangement fume-conducting bore sections.
