ABSTRACT:
A safety device for use in an escalator or moving walk for detecting stuck objects. A fine high-strength flexible wire is positioned through all the comb teeth and the skirts. A stretching of the wire triggers an electrical switch which in turn causes a relay to stop operation of the escalator or moving walk. Once this device is activated, only manual resetting will again activate the movement of the escalator.
