DEFINITION

Classification: 198/587

(under subclass 586) Apparatus wherein a conveyor is mounted for pivotal movement about an axis generally perpendicular to the ground.

(1) Note. Included here is a vibratory conveyor including two platforms which swing relative to each other and which are connected by moving drive links or gears for transmitting the motion of one platform to the other. The subclass also includes a vibratory conveyor having (a) two platforms which are connected together for relative swinging motion by a pin fixed on one platform and extending into an aperture on the other platform, and (b) a third platform which is mounted on one of the swingably connected platforms so that it can be extended or retracted relative thereto while the conveyor is operating. The subclass does not include a vibratory conveyor meeting only the requirement of section (a) of the preceding sentence.
