This takes the course shownby the arrow, finally reaching the dust room. Attached to the shafts aB at ^ and ^^ are dampers, by adjusting which some of the surface ofthe dust cages may be covered, and the draft at any point regulated.

Fig. 13. of a dust trunk, the opener being at a considerable distance from thebreaker lapper. The trunk is thought to give greatly added cleaningpower. A view showing the opener on one floor and the breaker lapperon another is shown at Fig. 13, in which the long wooden cleaningtrunk can readily be seen. Detached views of the trunk are shown inFigs. 14, 15, 16, 17. Fig. 17 shows clearly a sectional view. There are three compart-ments to the trunk shown. Through the upper passage a^ the light PREPARATORY PROCESSES AND MACHINES 21 cotton slowly passes, being drawn on by the induced air draught in thebreaker lapper. The bottom of the passage consists of grid bars throughwhich dirt may fall into the pockets b. The bottoms of these are hingedat d, so that they may be let down when it is desired to remove the bottoms d are held in position by springs /, on the outside of thetrunk, which press against short levers e, attached to t
