Abstract: A game of skill includes a dumbbell-shaped member having two resilient balls mounted on opposite ends of a dowel, a paddle, and an elastic strand having one end secured to the paddle and having its other end secured to the midpoint of the dowel. The paddle is used to strike a ball to cause the dumbbell-shaped member to rotate. The game depends upon the player's skill in keeping the dumbbell-shaped member rotating.

Abstract: A crusher includes a housing having an internal conduit for directing the advance of material therethrough. A plurality of cooperative pairs of rotatable crush rollers are disposed within the conduit. An endless flexible chain is operatively arranged to rotate each crush roller in a direction to cause material to be advanced through the crusher. Material to be crushed enters the conduit through an inlet and is progressively crushed between the rollers of each successively encountered pair. Crushed material is separated by size and discharged from the crusher via an outlet chute. The spacing between the bottom cooperative pair of crush rollers may be adjusted by selective rotation of a cam member.
