Abstract: A pulley is mounted in a surrounding hanging housing, open at the base end thereof and a cable is entrained over the pulley. The cable is provided with a pull means at one end the other end carries a load. Near each end of the cable are tripping brackets engaging a lever mechanism pivoted from the lower portion of the housing. The lever mechanism engages a pivoted tooth pawl. When the lever is tilted one way the pawl engages the load side of the cable to hold it in place when there is no pull on the other side. When the tripping bracket on the load side of the cable reaches the lower edge of the lever it tilts the right side of the lever upwardly which in turn engages a transverse pin on the pawl to move the end of the pawl teeth away from the load side cable and allow the load to descend. When the bracket on the pull side of the cable has risen to the lower left edge of the lever, the lever is tilted towards the load side allowing the pawl to engage the load side of the cable.

Abstract: A grappling hanging device for attachment to an overhead beam has a primary hanging hook mounted in a frame plate. A rectangular bar extends laterally from the base of the primary hanging hook. The width of the plate is slightly less than a circular area of the keyhole aperture and its thickness slightly less than the spaced walls of the keyhole aperture of the support plate. The opposite end of the support plate has a latching loop extending therefrom. When the lifting force is lowered, the support plate will rotate about the bar in the circular part of the keyhole opening, thereby swinging the opposed latch around to loop over the end of the hook. Once about 180.degree. rotation has occurred, the cross plate will slide to the closed end of the keyhole slot, and lock the hanging mechanism in place.
