Fitted on these shafts are the sleeves 5and s^. On the sleeves 5- and s^ are the gears R and R^ by which, throughsuitable driving mechanism, the sleeves are made to revolve loosely on theshafts a and B. The cages are firmly attached to the sleeves by fivearmed spiders seen in Fig. 27; the}^ consequently revolve loosely around PREPARATORY PROCESSES AND MACHINES 19 the shafts a and B. The ends of the cages open into chambers separatedfrom the rest of the machine. The depth of these chambers is readilyseen in Fig. 11, and their width and appearance outside of the machinein Fig. 10. These chambers are called dust flues. Inside the flues inthe middle of the machine is placed a fan F, 18 or 20 inches in revolves at a speed of about 1,200 rev
