Combination grease centrifugal separator and flame trap

Claim 1

A grease extracting baffle and flame trap for mounting in the exhaust duct of a ventilating system of a cooking unit comprising: a plurality of baffles each formed to provide a substantially cylindrically shaped open ended pocket for receiving the grease laden gases for causing them to acquire a rotary and whirling movement about an annular axis in the pocket, means mounting said baffles so that a first opening to each of said pockets arranged along their lengths is arranged with similar openings of the other pockets in a coplanar arrangement said mounting means including walls spaced from and transverse said open ended ends, said means being angularly positionable in the ventilating system of a cooking unit so that the first openings to said pockets receive the grease laden gases being vented to atmosphere, and a second opening for each of said pockets in the lower portion of said mounting means, said second opening being arranged laterally of the rotary and whirling movement of the gases in that pocket for exhausting the gases from that pocket downstream of said baffles, said second opening in each pocket being positioned along the annular axis of the rotary and whirling movement of the gases in that pocket, said means for mounting said baffles comprising a plate provided with a plurality of openings for receiving and aligning one baffle in each of said openings, each of said baffles being formed from a thin sheet of metal having its ends bent over to form flanges, said baffles being formed in an arcuate coNfiguration which extends through different openings in said plate with its end flanges overlapping parallel edges of the opening in which it is positioned whereby the arcuate configuration of said baffles form said pockets.
