ABSTRACT:
A pulley block system for releasable attachment to a sheet end and requiring no overhang beyond the sheet end. There is a first pulley block assembly having planar, parallel, spaced side portions and including a first pulley roller rotatably mounted between the side portions of the first pulley block assembly so that a line can pass over the first pulley roller. There is also a second pulley block assembly having planar, parallel, spaced side portions and including a second pulley roller rotatably mounted between the side portions of the second pulley block assembly so that a line can pass over the second pulley roller; and, interlocking apparatus for passing through the sheet to releasably interconnect the first and second pulley block assemblies with the sheet attached to and between the first and second pulley block assemblies. The preferred interlocking apparatus comprises a shaft extending outward perpendicular to one of the side portions of the first pulley block assembly and a bore through the second pulley block assembly perpendicular to the side portions thereof for receiving the shaft. In the preferred embodiment, the shaft has a T-shaped end comprised of opposed ears extending perpendicularly outward at the end of the shaft and the bore is disposed in a web portion of the second pulley block assembly and has at least one radial slot for the ears to pass through.
