Abstract
Abstract This invention concerns a system for mooring ships to structures consisting of two rigid arms ( 3 and 4 ), jointed at one end to two diametrically opposite points ( 7 and 8 ) on a crown-wheel, which can revolve on the mooring structure ( 2 ), and at the other end, by means of universal joints ( 31 and 32 ), to two floating caissons ( 5 and 6 ); these are connected by flexible couplings ( 51, 52 and 53 ), and the stem-post of the ship ( 1 ) passes between them. The invention concerns the mooring of oil-tankers or other vessels, floating appliances, etc.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
101 words
Apparatus for mooring floating objects to a mooring structure, said apparatus comprising: two elongated floating caissons, a horizontal ring rotatably mounted on said mooring structure, two rigid arms, each having one end pivotally connected to said horizontal ring and the other end pivotally connected to one of said caissons, the pivotal connections to said ring being located diametrically opposite each other, and elongated flexible means connecting the ends of the caisson attached to said rigid arms, so that an object moving between said caissons toward said mooring structure will strike said flexible means and thereby draw said caissons toward each other.
Claim 2
Dependent Claim
101 words
Apparatus for mooring floating objects to a mooring structure, said apparatus comprising: two elongated floating caissons, a horizontal ring rotatably mounted on said mooring structure, two rigid arms, each having one end pivotally connected to said horizontal ring and the other end pivotally connected to one of said caissons, the pivotal connections to said ring being located diametrically opposite each other, and elongated flexible means connecting the ends of the caisson attached to said rigid arms, so that an object moving between said caissons toward said mooring structure will strike said flexible means and thereby draw said caissons toward each other.
Claim 3
Dependent Claim
17 words
Apparatus as claimed in claim 1 in which said elongated flexible means comprises at least one net.
Claim 4
Dependent Claim
22 words
Apparatus as claimed in claim 1 in which the pivotal connection at at least one end of each arm has some elasticity.
Claim 5
Dependent Claim
34 words
Apparatus as claimed in claim 1 in which the pivotal connection at at least one end of each arm is a ball and socket joint in which the socket is lined with an elastomer.
Claim 6
Dependent Claim
41 words
Apparatus as claimed in claim 1 in which the pivotal connection between each arm and the corresponding caisson consists of a chain comprising a plurality of connected metal links embedded in a block of elastomer and covered with a protective sheath.
Claim 7
Dependent Claim
20 words
Apparatus as claimed in claim 1 in which said elongated flexible means are connected to the caissons by energy-absoring means
Claim 8
Dependent Claim
56 words
Apparatus as claimed in claim 1 in which said elongated flexible means comprises a line connected to said caissons between the pivotal connections of said caissons to said rigid arms, so that pressure against said line toward said mooring structure causes said caissons to swing toward each other about their pivotal connections to said rigid arms.
Claim 9
Dependent Claim
18 words
Apparatus as claimed in claim 7 comprising a plurality of lines attached to said caisson at different points.
Claim 10
Dependent Claim
20 words
Apparatus as claimed in claim 7 comprising a plurality of lines connecting said caissons, said lines being of different lengths.
Claim 11
Dependent Claim
12 words
Apparatus as claimed in claim 9 in which said lines are buoyant.
