AN EARLY FORM OF DUST EXTRACTOR, WITH HOPPER AND MOVABLE CARRIAGE forces in the shape of fans or steamvacua. The purification of air andelimination of dust have been treatedheretofore by the location of ex-haust fans in windows or walls ofthe room. But while this system pro-motes to some extent a displacementof impure air, it does not remove thedust and cotton fly until these ma- terials have passed over the area ofthe room, or some part thereof. Thefan in the window diffuses thedust before clearing it away. If then the problem of dust ex-traction is to be properly solved,means must be adopted to catch thedust particles as near as possible atthe line of their evolution, where DUST EXTRACTION IN COTTON MILLS 58; the stripping brush impinges on thecard cylinder. An early effort () made in this regard proved it tobe the remedial line of action.
