Abstract

6495. Etchells, J. C. Aug. 18. Lift cages, locking and unlocking.-In the usual type of switch operated by the door of a lift to prevent the cage from moving away from a landing when the door is open, the trigger or lever that operates the switch is mounted on any one of three pivots provided on the switch casing according to the class of door used, The switch is enclosed in a casing A, and the door, when closing, engages a trigger J pivoted at L, which presses up a sliding rod G insulated at H so that the spring- pressed piece E bridges the contacts C, D. When the door is opened, the rod G falls and breaks contact. The trigger may be mounted on the second pivot L', or a suitably modified trigger may be mounted on the third pivot L<2>.
