Abstract: An improved roller mill construction. Material to be milled or ground such is fed through a discharge opening in a hopper to a pair of cooperating rolls that are mounted within a housing. The discharge opening is enclosed by a sliding gate which is biased to the closed position and can be opened by manual operation of a pull rod. An adjustable setting mechanism is incorporated with the pull rod and enables the gate to be held at an infinite number of open positions. To adjust the spacing between the rolls, the shaft of one of the rolls is journalled within bearing assemblies that are mounted for sliding movement with respect to the housing. A rod is secured to each slidable bearing assembly and is threadedly connected to a shaft which carries a sprocket. By driving the sprockets in unison, the shafts will be rotated to thereby move the bearing assemblies and adjust the spacing between the rolls.

Abstract: A nut blanching arrangement in which nuts to be blanched are passed between first and second spaced, counter-rotating rollers. Each roller is provided with a plurality of hollow elastic tubular rings extending around its outer circumference. The tubular rings on the first roller are longitudinally aligned with respect to the tubular rings on the second roller such that each four adjacent tubular rings, two on each roller, form an opening through which the nuts pass during the blanching operation. In this arrangement, the nuts passing between the counter-rotating rollers are forced between the grooves of adjacent tubular rings such that the rings encapsulate and compress the nuts as they pass therebetween. The counter-rotating rollers are rotated at slightly different speeds such that during the blanching operation, the slight differential in the roller speeds causes the outer skin of the peanut to peel away from the nut meat.

Abstract: A shredding machine of the general type employed for comminuting difficult to shred material incorporates a torque cushioning device for the purpose of minimizing breakage of the comminuting teeth or knives of the apparatus when the teeth encounter metal or other objects which impose a torque overload on the rotating teeth.

Abstract: In a beam-backed cluster-type strip mill each roll is driven separately from a vertical motor placed on top of the housing through a floating right-angle gearbox. The gearbox is keyed onto one end of each roll and is so suspended that only pure torque is transmitted to the roll and the reactions as well as the weight of the box are absorbed by the suspension means.Roll oscillating mechanism, forcing the rolls to travel axially back and forth far enough to efface marks left by the backing casters, is incorporated in the gearbox.This drive possesses substantial advantages over conventional drives, which make the mill more accessible, and save space. Moreover it makes possible various roll configurations by adding supplementary rolls to the cluster pattern thereby increasing the range and scope of the mill.
