ABSTRACT:
A safety device to arrest movement of an elevator car guided by non-metallic guide rails employs a friction surface mounted on a wedge. The wedge is located in proximity to an angular horizontal locator when in the unengaged position. Upon activation of the wedge during an overspeed condition the horizontal locator urges the friction surface of the wedge into contact with the guide rail.
