to'protectthe casing. This lining terminates atthe ends of the compartments, and isspaced to provide an annular recess 22,V Figure 5,
for receiving Vthe elements of the-partition.
Each partition lembodiesV a spider 23, in-

Invvardly of the slot-s 42, the segmental discharge plate is provided With a. plurality7 of groups. of circumferentially ext-ending slots 43, Each coacting shutter-plate 39 is provided with 'an outer curved group of slots or openings 44 and 45, adapted forv movement into and out of registration respectively with the slots 40 and 41. The shutter-plate is provided with an intermediate curvedv groupV of slots or openings 46, 'disposed in staggered relation to theV slots 44 and 45 and'being twice as Wide as these slots. Slots 46 are adapted for movement into and out of registration With slots 42. Circumferentially extending slots 47 are formed in the inner end of the segmental shutter-plate and are adapted for permanent registration With the slots 43. When slots 44 yand 45 are in Aregistration with slots 40 and 4l respectively, slots 46 Will register With slots 42.
` When the shutter-plate is turned sufficient# ly so that slots 44 and 45 are Vjust out of registration with slots 40 and 4l respectively, slots i 46, due to their increased Width Will still reg ister with slots 42.
