ABSTRACT:
Two generally U-shaped pieces are adapted to fit together end-to-end so that when they are nested in an appropriately-sized passage in an escalator entry box, they cooperate to form a generally cylindrical actuator that at one end has brushes protruding through the opening of the entry box and that is slideable in the entry box over the handrail to actuate a safety shutoff switch located therein in the unlikely event of a foreign object being pulled by the handrail into the entry box.
