ABSTRACT:
A vertical-horizontal passenger conveying system includes elevator cars provided with individual drives for travel in intersecting vertical and horizontal shafts. The shafts have fixed and movable vertical guide rails with steps which are engaged by roller chains of the drives wherein more than one car can travel in the same shaft at the same time. The movable rails are latched in a vertical position for vertical travel of the cars and are pivoted out of the way for entrance of a car into an horizontal shaft. Supports on the cars or in the shafts relieve the force applied to the steps through the chains to permit movement of the movable rails. Deflecting and tensioning rollers for the chains have flanges for running on horizontal guide rails in the horizontal shafts.
