Miller Creek Mystery

Up in the rafters there is a collection of owl pellets and a wasp nest in plexiglass for close-up observations? I don't get what's going on with the string and pulleys up there, and what looks like a pin hasp. Didn't notice it while I was there and wish I could get a better look.
