ABSTRACT:
A descent apparatus to control the descent of people or materials from physical heights, for example, buildings, aircraft, ships, trees or mountains and may be used for business, pleasure, and military purposes, under routine or emergency circumstances. The apparatus employs a movable lever arm spring bias toward the braking disposition which influences the amount of friction between various sections of the cable used for lowering as the various sections of the cable interactively contact one another in opposed directions about multiple rollers.
