摘要

A block and tackle system having two different purchases is operated from a single line. The system includes a primary purchase system and a secondary system having a higher purchase than the primary system. The primary and secondary systems are separated by a one-way block, and the secondary system is connected back to a floating block in the primary system. The secondary system is activated upon initial ease of the line from any given position, with the one-way block locking the line in the ease direction.
