1452804 Passenger conveyers MITSUBISHI JUKOGYO KK 27 March 1974 [30 March 1973] 13671/74 Heading B8A [Also in Division B7] A passenger conveyer has high speed zones 3, 4 (Fig. 1), deceleration zones and acceleration zones 5, 9, respectively, low speed zones 6, 8, and a turning zone 7. The sloping attitude of passenger supporting slats 1 is controlled by the spacing of a pair of parallel guide rails 10c, 11c, from another similar pair nearer to the other end of the slats. The rails guide rollers 12c, 13c, pivotally mounted on the slats. In each high speed zone, the slats are driven by a respective endless chain 32 having surfaces 45 which engage and drive members 44 depending from the slats 1. In the slow speed zones (Fig. 3), the radially inner and outer ends of each slat have rollers 17, 17, which are engaged by respective sockets 21, 16, on endless driving chains 18, 14. In the turning zone, the radially innermost rollers 17 remain in engagement with the sockets 21, but the outer rollers 17 are guided by a guide 24. In this zone, the slats are driven by dogs 28 on an endless chain 25. Each slat carries a handrail (31) (Fig. 4, not shown). A sliding joint is provided between the laterally extending edges of adjacent slats.
