ABSTRACT:
A self-contained emergency escape device includes a first larger jaw, a second smaller jaw, a bolt mounting the jaws for relative movement, a yoke defined at the upper end of the first jaw, and a take-up spool secured within said yoke. Several brake plugs are secured to the interior edges of the jaws, and complementary cut-outs are defined in the opposing edges of the jaws. A sturdy cable is an integral part of the escape device, and extends through the device in a tortuous path extending over the brake plugs and subsequently being stored, when not in use, on the spool. A sling is secured to the jaws so that the user can not be separated from, or fall away from, the emergency escape device. Also, a fail-safe mechanism prevents the jaws from being forced too far apart. One uses the device by applying manual pressure to the jaws to increase the frictional resistance on the cable and thus controlling the rate of descent.
