Abstract:
1. In a horizontal lifeline load attachment traversing device which is capable of traversing intermediate lifeline support members which support a horizontal lifeline without detachment from said lifeline, said load attachment traversing device including a grooved roller for engaging the upper surface of said lifeline for rolling movement along the length thereof, a frame having an upper portion secured to said roller and a lower portion including a substantially vertical portion extending downwardly below the level of the lower surface of said lifeline and including a lower arm and means carried by said lower arm for securing a load to said device, and a rotatable member in the form of a paddle wheel having a plurality of radially spaced apart paddles carried by said lower arm for preventing said device from vertical movement so that said device cannot be unintentionally removed from said lifeline, said paddles being adapted to rotate about a horizontal axis when engaged by an intermediate support member, the improvement comprising: said paddles being comprised of first and second sets of paddles, each set being rotatable about the same axis; an axle defining said axis; said first set of paddles being substantially fixed on said axle; said second set of paddles being capable of some rotation relative to said axle and being movable axially on said axle between a first position wherein it is axially spaced from said first set and a second position where it is in substantial axial alignment with said first set, and whereby said device can be attached to or detached from said horizontal lifeline when said second set of paddles is in said second position.
