Title: Improvements in or relating to controllers for electric motor driven travelling devices
IPC: B66B1/08
Filed: 1944-06-16
Abstract: 578,792. Lift systems. IGRANIC ELECTRIC CO., Ltd. June 16, 1944, No. 11521. Convention date, June 17, 1943. [Class 40(i)] In a push button lift system of the kind in which the car is started by an attendant, the landing and car buttons charge condensers to stop a car when it reaches the appropriate point. In the two-car system shown in Fig. 6, the up and down buttons 91-95 of the respective floors charge condensers 105 and the floor buttons of the respective cars charge condensers 103, 104. Each car controls three floor selectors, one of which connects up the condensers controlled by the car buttons to a winding 69b of a stopping relay whether the car is going up or down and the others of which connect the condensers charged by the up landing buttons to the winding 69a of the relay when the car is rising and those charged by the down buttons when it is descending. The control switches on the car, which normally are operated only momentarily, may have additional contacts to enable a relay to be operated to cut off the stopping relay when a car is full. To enable the car to be brought to rest gradually, the stopping relay may, as shown in Fig. 3, lock up over a third winding 37c, shunt a resistance in the field circuit and energise a further relay 38 which, owing to the effect of a resistance/condenser circuit 39, 40 pulls up sluggishly, the motor circuit remaining closed until the energization of the latter relay. In another arrangement, Fig. 4 (not shown), smaller condensers are used and are made to cause the firing of a gas-filled discharge tube to operate the stopping relay. In another arrangement, Fig. 5 (not shown), the stopping relay locks up, shunts a resistance in the field circuit and opens the circuit of a magnet to bring a cam on the car into the path of a stopping switch at the landing.
