Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
168 words
A device for mooring a ship comprising a mounting member, a suction cup assembly having a main body with two major surfaces, at least one continuous, circular lip rubber projecting outwardly from one major surface of said main body and defining a space in which a partial vacuum is produced by a vacuum pump when said suction cup assembly is attached to a surface of the ship, said suction cup assembly including a supporting member intermediate said mounting member and said main body, and means interconnecting the supporting member and said main body, means including a universal joint for supporting said suction cup assembly on said mounting member annd a plurality of power cylinders mounted on the mounting member and connected directly to the suction cup assembly whereby the assembly may be freely and positively moved in vertical and horizontal directions about said universal joint by actuation of said power cylinders, to position said suction cup assembly against the surface of the ship regardless of the curvature thereof.
Claim 2
Independent Claim
168 words
A device for mooring a ship comprising a mounting member, a suction cup assembly having a main body with two major surfaces, at least one continuous, circular lip rubber projecting outwardly from one major surface of said main body and defining a space in which a partial vacuum is produced by a vacuum pump when said suction cup assembly is attached to a surface of the ship, said suction cup assembly including a supporting member intermediate said mounting member and said main body, and means interconnecting the supporting member and said main body, means including a universal joint for supporting said suction cup assembly on said mounting member annd a plurality of power cylinders mounted on the mounting member and connected directly to the suction cup assembly whereby the assembly may be freely and positively moved in vertical and horizontal directions about said universal joint by actuation of said power cylinders, to position said suction cup assembly against the surface of the ship regardless of the curvature thereof.
Claim 3
Dependent Claim
44 words
A device as set forth in claim 1 wherein a fender is attached to said one major surface of said main body, said fender projecting outwardly from said one major surface a distance less than said lip rubber to limit compression of the latter.
Claim 4
Dependent Claim
47 words
A device as set forth in claim 2 wherein a plurality of buffer members are positioned between the other major surface of said main body of said suction cup assembly and said supporting member for absorbing impacts between the surface of the ship and the supporting member.
Claim 5
Dependent Claim
48 words
A device as set forth in claim 1 wherein a a plurality of buffer members are positioned between the other major surface of said main body of said suction cup assembly and said supporting member for absorbing impacts between the surface of the ship and the supporting member.
