  • Snatch block with improved hook bolt assembly
    Patent number: 4614332
    Abstract: This concerns a snatch block for free stringing rope to a sheave supported between two side plates, one of which is movable. One of the side plates, called a swing plate, is rotatable with respect to the sheave. A removable bolt holds the two side plates together. Means are provided to prevent the bolt from falling completely out of the non-movable side plate when the other side plate is moved. Further, special means are provided for the bolt to help support the spool and further novel means are provided to aid in preventing the trunnion and hook from falling off the spool when the side plate is swung free.
