FIG. 4. A SPECIALLY-DESIGNED RESPIRATOI the lips (Fig. 3), in the hope of miti-gating, to some extent, the effects ofdust inhalation. This curious formof respirator has been used by hun-dreds of strippers in the Lancashirecotton mills; and from sheer custombids fair to last sometime longer.That it has done good service isbeyond doubt. In some factoriesother specialized forms of respiratorhave been used and welcome bene- fits have been derived from these (Fig- 4). Efforts are now in progress forthe complete elimination of the dustclouds. No such evolutions are per-mitted to escape into the card roomof the mill. As rapidly as the dustis generated in the carding machineit is caught up into trunks or tubesand conveyed away to external partsof the mill by powerful extracting 5»4 CASSIERS MAGAZINE

FIG. 5. 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 (Fig.5) made in this regard proved it tobe the remedial line of action. Anappliance was designed to cover thespace immediately above the strippingbrush by a full-sized hopper, withtrunk connected to an en
