Title: Elevator call measuring means
IPC: B66B1/22
Filed: 1951-04-20
Abstract: 688,094. Push button lifts. WAYGOOD-OTIS, Ltd. April 20, 1951 [April 28, 1950], No. 9249/51. Class 40 (i) [Also in Group XL(c)] The operation of a multi-car lift system is modified in accordance with the total waiting time of calls at a number of floors, as registered by condensers individual to the floors, or jointly in accordance with the total waiting time and with the number of calling floors. Similar apparatus can be used in a single car system for statistical purposes or for stopping and reversing the car on an up journey before the highest calling floor when lower calling floors have been by-passed on previous journeys. The Figure shows the "down" call controlling apparatus for floors 3, 4 and 5. The operation of a calling button TB breaks down the associated indicator tube and the resulting change of potential distribution blocks the rectifier section LCR of a double tube LCT which normally acts as a shunt to a timing condenser QTC. This condenser thus begins to charge, causing a gradually increasing current to flow via triode section of tube LCT, the individual resistor RTA and the resistors RCTA1 and RCTA2 which are common to the timing circuits of all the floors. The current through these last mentioned resistors, which determines the bias of the upper triode of a double tube-LCCT, thus depends on the total waiting time at all floors and when it reaches a critical value causes the operation of the anode relay XVO. Optionally, also, a portion of the discharge through the indicator lamp passes via an individual resistor RCA and a common resistor RCCA, the voltage drop across which is thus proportional to the number of calling floors but independent of the times they have been calling. This voltage controls the current in the other element of the double tube LCCT which, as shown, shares an anode relay with the element previously mentioned. Separate anode relays may, however, be provided. When a car approaches a calling floor, its wiper DPB engages the floor contact DH and (contact PRNS being closed) XSM operates to bring it to rest. When the car has lost enough speed, contacts ASM close to apply an extinguishing potential to the indicator tube. In a modification, Fig. 2 (not shown), similar effects are produced in a system in which calls are registered by magnetically held relays.
