Between the inner end of the fixed or stationary yoke, an'd an adjustable washer 28 threaded on the cam bar, is interposed a spring 29 that is coiled about the cam bar, and this'25 spring which holds the cam head against the. cams, also provides resilient means for forcing the trough on its inner stroke inwardly of the trun nion after the cam- actionv has caused the out stroke of the trough. drum so that the successive -streams of material falling fromfthe topV of the low-speed drum will each be batted by a vane of the rotary batf. . 'I’he impact of the falling solids on the bat. _ may to some extent, break-up some ci'v the solids, but the main crushing action, or reduction o1' the solids takes place when the 'successive vanes of the rotating bat toss the solids laterally, across the interior of the drum, against the wall of the lThe inner end of the yoke thus supports the_ cam bar, and the outer end of the yoke supports rotarydrum.

Be- _ the inner periphery of the ring moving in a path tween the journaled end ofthe bolt and the yoke above the periphery of one oi' the retaining heads an adjusting nut 32 is threaded, and a cushion of the rotaryv bat. Thus, as the d'eñecting ring washer or bumper 3l is also mounted on the bolt ~ moves with the drum,l any material falling ’on the defiecting ring is guided or deflected onto the 40 adjacent the lug 3|, and the bolt .is fashioned with >a head 34 exterior of the lug Il.A By means of the bolt-which is adjustable with relation to the stationary yoke, and the'adjusting nut 22 on the bolt, the length of the stroke of the trough _ 45 may be adjusted or varied _to suit different condi- ' tions, and the movement of the trough maybe adjusted to prevent lost motion. This reciprocating movementoi the trough dis lodges the material from the superimposed hop ’ ` per and the material is i'ed in a constant stream 50 through the intake trunnion to the interior 'of the drum, where it is picked up, and dropped in a shower or screen by the successive buckets I5 rotary bat. This ring also prevents splashing'of ' 40 water through _the outlet or discharge trunnion~ of the drum. ' ‘ ' To control the outflow or discharge o! the wet pulp through the discharge trunnion I employ .a circular bame plate 45, which is suspended loosely on one of the journal ends of the rotary bat with in the defiecting ring 44 and located between the ring and the discharge‘opening‘ of the head 4.
