Abstract

807,046. Lift control systems. HALL Ltd., J. & E. Feb. 15, 1957 [Feb. 23, 1956; Nov. 13, 1956], Nos. 5644/56 and 34696/56. Drawings to Specification. Class 78 (3). [Also in Group XXV] A lift system of the kind in which a plurality of cars serve a number of floors, the cars are arranged to return to a despatching floor, and the landing calls are supervized by a despatch signal initiating system to determine whether a landing call can conveniently be attended to by a car already on a trip, or whether a further car that is waiting, at the despatching floor should be given a despatch signal to initiate despatch of this car to attend to the landing calls; is characterized in that the despatch signal initiating system comprises means for selecting the order of despatch of cars from the despatching floor, timing means for providing a despatch interval for delaying despatch of the car first selected, a despatch signal device for each car for starting the associated car when the despatch interval has expired and there is an outstanding landing call, and means for transferring starting preference from the first selected car to the next when the despatch signal device of the first car is operated. A detailed description is given of an electric control system for an installation comprising three cars serving seven floors, which system effects the series of operations set out above.
