Feb. 8, 1930, No. 4353. Convention date, Feb. 9, 1929. [Class 78 (ii).] Electric plant.-In a single-stage hoisting plant switching means are so arranged that on the opening of a shaft door a safety brake will only come into operation if the cage is in the neighbourhood of the stopping points. When a shaft door is opened, one of the contacts 2 is opened and the supply of current to the coil of a locking magnet 1 is cut off. The armature of this magnet falls and engages the teeth of a rack 9 on the brake lever 3 thereby ensuring that the lever can only be moved into braking position. The opening of the contact 2 also interrupts the supply of current to the relay 14 which breaks the circuit of the safety-brake magnet (not shown) at the contacts 15 as soon as it becomes de-energized. This circuit is, however, completed by the travelling nut 13 and a pair of contact rails 12 on the depth indicator 11 except when the nut slides off the rails when the cages are nearing the stopping position. A switch 10 on the brake lever 3 short-circuits the contacts 15 when the brake lever is in the " on " position and so prevents the application of the safety brake. The device is placed out of action when goods only are being carried by a switch 7. A contact 16 on the lever 3 causes lamps 5 to be lit at the stopping points as soon as the brake is applied. Lamps 4 at the stopping points are switched in by a switch 8 on the magnet 1 as soon as the brake lever is locked.
