  • Patent number: 4006686
    Abstract: A blanket hooking means for use with a blanket cylinder to facilitate attachment of a blanket around the blanket cylinder with a minimum amount of effort and requiring little set-up time. The hooking means include a pair of arcuate brackets which can be secured in the blanket cylinder opening by screws which are received in pre-existing holes in the floor of the opening in the cylinder. The hooking means also includes a pair of hook members which can receive opposite ends of the blanket and cause the blanket to be securely stretched around the blanket cylinder. The hook members are slidably supported in arcuate slots in the brackets and include projections which are received in key-hole slots in the ends of the blanket. Each hook member includes a pair of adjusting screws which can be tightened so as to abut the side walls of the cylinder opening.
