Abstract
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. The screws can be forced against the cylinder side walls causing an arcuate movement of the hook members in the arcuate slots and causing a tightening or stretching of the blanket around the blanket cylinder. Each adjusting screw is surrounded by a compression spring which is compressed between the hook member and the cylinder opening wall. The tension of the compression springs is sufficient to automatically compensate for any slack which may develop due to stretching of the blanket during use.

292 words
A blanket hooking means for securing a blanket around a blanket cylinder having a longitudinal axis and including a cylindrical outer surface and wherein said blanket cylinder includes a narrow elongated longitudinal cylinder opening in said cylindrical outer surface extending parallel to the axis of the cylinder and having longitudinally extending generally opposed cylinder opening walls defining generally radially extending planes with respect to the longitudinal axis of said cylinder and intersecting the cylindrical outer surface and wherein said blanket includes opposite ends and a plurality of aligned slots in said ends, said blanket hooking means comprising: bracket means removably secured to said blanket cylinder and disposed within said cylinder opening between said cylinder opening walls, a pair of elongated longitudinally extending blanket hooking members supported adjacent to said cylinder opening walls and in spaced parallel relationship to each other, at least one of said blanket hooking members being slideably supported by said bracket means for slideable movement toward and away from one of said cylinder opening walls, said hooking members including a plurality of projecting blanket securing projections aligned parallel to the longitudinal axis of said cylinder for receiving said aligned slots in the ends of said blanket, and means for adjustably forcing said at least one blanket hooking member away from said one of said cylinder opening walls for stretching said blanket around said cylinder, said bracket means including a pair of arcuate brackets received in said cylinder opening in longitudinally spaced apart relationship, said arcuate brackets each including an arcuate slot therein, and wherein said hooking members each include a rod secured thereto, said rod being slideably supported by the pair of arcuate brackets in said arcuate slots whereby each of said hooking members is slideable along said slot.
Claim 2
Dependent Claim
292 words
A blanket hooking means for securing a blanket around a blanket cylinder having a longitudinal axis and including a cylindrical outer surface and wherein said blanket cylinder includes a narrow elongated longitudinal cylinder opening in said cylindrical outer surface extending parallel to the axis of the cylinder and having longitudinally extending generally opposed cylinder opening walls defining generally radially extending planes with respect to the longitudinal axis of said cylinder and intersecting the cylindrical outer surface and wherein said blanket includes opposite ends and a plurality of aligned slots in said ends, said blanket hooking means comprising: bracket means removably secured to said blanket cylinder and disposed within said cylinder opening between said cylinder opening walls, a pair of elongated longitudinally extending blanket hooking members supported adjacent to said cylinder opening walls and in spaced parallel relationship to each other, at least one of said blanket hooking members being slideably supported by said bracket means for slideable movement toward and away from one of said cylinder opening walls, said hooking members including a plurality of projecting blanket securing projections aligned parallel to the longitudinal axis of said cylinder for receiving said aligned slots in the ends of said blanket, and means for adjustably forcing said at least one blanket hooking member away from said one of said cylinder opening walls for stretching said blanket around said cylinder, said bracket means including a pair of arcuate brackets received in said cylinder opening in longitudinally spaced apart relationship, said arcuate brackets each including an arcuate slot therein, and wherein said hooking members each include a rod secured thereto, said rod being slideably supported by the pair of arcuate brackets in said arcuate slots whereby each of said hooking members is slideable along said slot.
Claim 3
Dependent Claim
293 words
A blanket hooking means for securing a blanket around a blanket cylinder having a longitudinal axis and including a cylindrical outer surface and wherein said blanket cylinder includes a narrow elongated longitudinal cylinder opening in said cylindrical outer surface extending parallel to the axis of the cylinder and having longitudinally extending generally opposed cylinder opening walls defining generally radially extending planes with respect to the longitudinal axis of said cylinder and intersecting the cylindrical outer surface and wherein said blanket includes opposite ends and a plurality of aligned slots in said ends, said blanket hooking means comprising: bracket means removably secured to said blanket cylinder and disposed within said cylinder opening between said cylinder opening walls, a pair of elongated longitudinally extending blanket hooking members supported adjacent to said cylinder opening walls and in spaced parallel relationship to each other, at least one of said blanket hooking members being slideably supported by said bracket means for slideable movement toward and away from one of said cylinder opening walls, said hooking members including a plurality of projecting blanket securing projections aligned parallel to the longitudinal axis of said cylinder for receiving said aligned slots in the ends of said blanket, and means for adjustably forcing said at least one blanket hooking member away from said one of said cylinder opening walls for stretching said blanket around said cylinder, said hooking members including a plurality of projecting brackets integrally attached thereto, and wherein said bracket means include a pair of arcuate brackets, each of said arcuate brackets including arcuate slots therein, at least two of said projecting brackets including aligned bores for receiving a rod therethrough, said rod being slideably supported in said arcuate slots for movement toward and away from said cylinder opening walls.
