ABSTRACT:
The invention relates to conveyor apparatus, particularly for use in conveying large quantities of heavy bulky and/or dry materials over a long distance. Moreover, the apparatus of the invention may be constructed in out-of-the-way areas over deteriorated or difficult courses, such as rubble. This is achieved by the use of a tube-like elongated passage through which a plurality of joined conveyor cars pass. The elongated passage has openings in the bottom for receiving therealong spaced apart primary windings for a linear electric motor. The cars, in turn, have mounted in the bottom surface thereof the secondary of the motor. The apparatus includes air vents for accommodating air movements ahead of and behind the cars switching arrangements and provision for loading and unloading.
