Abstract
Abstract The combination of a marine structure having a foot disposed in the bed of a body of water and first means for reducing and preventing scours of the bed at the foot of the marine structure with the foot in place, second means mounting the first means for general vertical sliding movement along the foot, the first means having opposite first and second end portions, the first end portion being more remotely spaced from the foot than the second end portion in a first in-place operative position of the first means, and the second means mount the second end portions of the first means for the latter sliding movement.

Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
154 words
The combination of a marine structure having a foot disposed in the bed of a body of water and first means for reducing and preventing scours of the bed at the foot of the marine structure with the foot in place, second means mounting said first means for general vertical sliding movement along said foot, said first means having opposite first and second end portions, said first end portion being more remotely spaced from said foot than said second end portion in a first in-place operative position of said first means, said second means including vertical channel guiding means carried by said foot to which is slidably guidably interconnected said second end portion for guided vertical movement of said second end portion and said first means relative to and along said foot, and cable means connected to said first means for slidably moving said first means relative to and along said vertical guiding means.
Claim 2
Dependent Claim
154 words
The combination of a marine structure having a foot disposed in the bed of a body of water and first means for reducing and preventing scours of the bed at the foot of the marine structure with the foot in place, second means mounting said first means for general vertical sliding movement along said foot, said first means having opposite first and second end portions, said first end portion being more remotely spaced from said foot than said second end portion in a first in-place operative position of said first means, said second means including vertical channel guiding means carried by said foot to which is slidably guidably interconnected said second end portion for guided vertical movement of said second end portion and said first means relative to and along said foot, and cable means connected to said first means for slidably moving said first means relative to and along said vertical guiding means.
Claim 3
Dependent Claim
30 words
The combination as defined in claim 1 wherein said first means is positionable at a second position at which said first and second end portions are both adjacent said foot.
Claim 4
Dependent Claim
37 words
The combination as defined in claim 2 including first and second cable means secured respectively to said second end portion and between said first and second end portions for controlling gravity-influenced sliding movement of said first means.
Claim 5
Dependent Claim
25 words
The combination as defined in claim 3 wherein said first means are defined by a plurality of separate sections individually slidably movable along said foot.
Claim 6
Dependent Claim
33 words
The combination as defined in claim 3 wherein third means are provided for expanding and contracting said first means to respectively increase and decrease the distance between said first and second end portions.
Claim 7
Dependent Claim
40 words
The combination as defined in claim 3 wherein said first means is a lattice girder of a generally triangular outline having an apex defining said first end portion and a base remote from said apex defining said second end portion.
Claim 8
Dependent Claim
56 words
The combination as defined in claim 3 wherein said first means is a lattice girder of a generally triangular outline having an apex defining said first end portion and a base remote from said apex defining said second end portion, and said apex points in a direction away from said foot in said first in-place position.
Claim 9
Dependent Claim
74 words
The combination as defined in claim 3 wherein said first means is positionable at a second position at which said first and second end portions are both adjacent said foot, said first means is a lattice girder of a generally triangular outline having an apex defining said first end portion and a base remote from said apex defining said second end portion, and said apex points in a downward direction in said second position.
Claim 10
Dependent Claim
25 words
The combination as defined in claim 1 including cable means secured to said second end portion for controlling gravity-influenced sliding movement of said first means.
Claim 11
Dependent Claim
32 words
The combination as defined in claim 1 including cable means secured to said first means between said first and second end portions thereof for controlling gravity-influenced sliding movement of said first means.
Claim 12
Dependent Claim
25 words
The combination as defined in claim 1 wherein said first means are defined by a plurality of separate sections individually slidably movable along said foot.
Claim 13
Dependent Claim
33 words
The combination as defined in claim 1 wherein third means are provided for expanding and contracting said first means to respectively increase and decrease the distance between said first and second end portions.
Claim 14
Dependent Claim
40 words
The combination as defined in claim 1 wherein said first means is a lattice girder of a generally triangular outline having an apex defining said first end portion and a base remote from said apex defining said second end portion.
Claim 15
Dependent Claim
56 words
The combination as defined in claim 1 wherein said first means is a lattice girder of a generally triangular outline having an apex defining said first end portion and a base remote from said apex defining said second end portion, and said apex points in a direction away from said foot in said first in-place position.
Claim 16
Dependent Claim
74 words
The combination as defined in claim 1 wherein said first means is positionable at a second position at which said first and second end portions are both adjacent said foot, said first means is a lattice girder of a generally triangular outline having an apex defining said first end portion and a base remote from said apex defining said second end portion, and said apex points in a downward direction in said second position.
Claim 17
Dependent Claim
42 words
The combination as defined in claim 1 wherein said first means is positionable at a second inoperative position at which said first and second end portions are both adjacent said foot and said second end portion is above said first end portion.
Claim 18
Dependent Claim
53 words
The combination as defined in claim 16 wherein said first means is a lattice girder of a generally triangular outline having an apex defining said first end portion and a base remote from said apex defining said second end portion, and said apex points in a downward direction in said second inoperative position.
Claim 19
Dependent Claim
26 words
