    Abstract: The arrival of each of four dual-hoistway shuttle elevators S1-S4 is synchronized with a selected one of ten local elevators L1-L10, or ten low rise elevators L1-L10 and ten high rise elevators H1-H10 at a transfer floor 26 by limiting 140 the speed of the shuttle, gradually 149, or rapidly 154, 155 decreasing the speed of the shuttle, delaying a local elevator by holding its doors open for extra time, or controlling the speed of a local elevator, by cancelling or avoiding hall calls. Empty local elevators may be allowed to remain at the high end of the building, or compelled to travel to the lobby if needed. Elevators approaching a transfer floor may be synchronized by adjusting the speed of one of them until the remaining distance is the same for both. Hall calls may be prevented, cancelled, or negatively biased in dependence upon the tardiness of a local elevator. Synchronization may be achieved between shuttle elevators and local elevators, between portions of multi-hoistway shuttle elevators, and amongst elevator combinations employing three or more hoistways.

    Abstract: A first slidable auxiliary pinion (58a) on the bottom of a horizontally moveable elevator cab A (Figs. 2-6) disposed on a car frame (14) or a landing is moved out from under the cab toward another car frame (13) or landing by means of a motorized pinion (56) until it engages a motorized pinion (57) on the adjacent car frame (13) or landing, which then pulls the auxiliary pinion and the entire cab toward the other car frame or landing until a main rack (45) fixed to the bottom of the cab engages a motorized pinion (34) on the other car frame (13) or landing, which pinion then pulls the entire cab onto the other car frame or landing. The auxiliary racks (58a, 58b) may be mounted on a common auxiliary rack member (58), or may be separate. The auxiliary motorized pinions (55, 56, 57) may be bidirectional, or may be unidirectional and mounted on the same shaft with main pinions (32a, 32c; 33a, 33c; 34a, 34c).
