ABSTRACT:
The escalator has steps with vertical planar cleated risers which mesh with cleated trailing edges of the adjacent step. The step chains are selectively kinked and unkinked to provide for a constant spacing of adjacent step axles throughout the path of travel of the escalator. The steps thus display a constant horizontal velocity. The escalator can be adapted to follow a fixed center constant radius in plan helical path of travel.
