DEFINITION

Classification: 198/586

(under subclass 570) Apparatus wherein one conveyor of the system is repositionable relative to another by moving either the entire conveyor or only a portion thereof.

(1) Note. Included here is a system having means for moving the support frame of a first conveyor so that said first conveyor lifts a load from a second conveyor, said first conveyor then being operated to convey said load. A specific example is a swingable frame that carries an endless belt, said frame being moved upward relative to power-driven rollers so that the endless belt lifts a load from said rollers, and said endless belt then moving said load by its orbital motion.

(2) Note. If coacting conveyors which grip a load therebetween are classifiable as plural conveyors (either because a load is transferred between the coacting conveyors, or because a load is transferred between such conveyors and

another conveyor not coacting therewith), a claimed arrangement for moving one of the coacting conveyors relative to another is classifiable in this subclass or an indent thereof.
