ABSTRACT:
An elevator including a cage disposed in a vertical passage and having a door has a plurality of pinions carried on a pair of substantially horizontal rotary shafts supported along a pair of edges, respectively, of at least the top or bottom of the cage. The shafts extend in parallel to a pair of opposite sidewalls of the passage which lie at right angles to the door. A plurality of vertical racks are secured to the sidewalls of the passage, each engageable with at least one of the pinions. An irreversible driving device is associated with the pinions for rotating them to raise and lower the cage along the racks.
