Abstract

752,235. Filtering gases. MINE SAFETY APPLIANCES CO. Feb. 15, 1954, No. 4392/54. Class 8(2). An air filter comprises a box-like casing having side walls 1, Fig. 6, connected at the top by an integral wall 2, at the bottom by a rib 5 and at the back by a wall 3 having a filtered air outlet 4 and a removable perforated cover 9, Fig. 4, serving to clamp a removable sheet 13 of porous flexible material e.g., filter paper in sealing contact with the casing and to provide a dust-laden air inlet which extends across the front of the casing, round the bottom and across part of the back 3. The sheet 13 and cover 9 are located by and bear against flanges 6 of the side walls 1. A rib 10 of the cover 9 engages a groove 11 in the top wall 2.
