Abstract

468,752. Locking control ropes of lifts. PRESTON, P. Jan. 8, 1936, No. 642. [Classes 78 (ii) and 78 (iii)] A lift control-handrope F is normally gripped by a brake block G on a pivoted arm D pressed into engagement by a spring H, the pressure being regulated by a nut I. When a lift gate is open, release of the grip is prevented by a spring-pressed wedge J which is, however, withdrawn through linkwork P, O, P when a forked lever N is rocked by a roller M on closure of the lift gate L. The rope grip may then be released by rotation of a cam B by means of a handle A. The handle is formed with a triangular key projection A<1> which can only be inserted or removed when the grip is operative and may serve as a master handle for the landing gates from which also it is only removable when the gates are locked.
