Abstract
327,581. Milne, S. April 13, 1929. Pulping-engines.-The beater roll or the bedplate of a, pulping-engine is supported in a lever system allowing automatic increase of the pressure, progressively as the beating proceeds. The beater roll a is carried by levers b pivoted at b* adjustably connected to a lever f pivoted at f<1> linked to a lever h which carries a weight i suspended from a nut h<2> on a long screw h<1> which may be rotated by a hand wheel o, or driven from the beater roll trunnion or other member by belting and complementary stepped-cone pulleys actuating a worm &c. The worm wheel, m, is loose on the screw h<1>, engagement being through a clutch n connected with a lever s 'and a rod q carrying an adjustable stop r, a hand-wheel b<3> with a worm wheel b<4> &c. being also provided. As the beating proceeds the weight i is moved towards the fulcrum of the lever h until a projection on the nut h<2> engages the stop r. Scale markings may be provided on the lever h. Modifications of the invention include different bed-plate positions and an arrangement wherein the bed-plate is moved, the beater roll bearings being stationary. Specification 207,716 is referred to.
