Abstract
Abstract A device for protecting a pile from ice formations collecting on and subsequently extracting the pile as a result of a variation of tide level including a tapered guard member secured to the pile. The tapered guard member is firmly secured to the pile by horizontal stiffening rings and vertical fin members which also serve to prevent deformation of the guard member taper as a result of interaction with the ice formations. The guard member comprises a one piece jacket connected by a vertically extending joint or may comprise a series of tapered strips, a series of interconnected curved sections, or a series of interconnected rectangular ribs.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
167 words
A pile protection for preventing an ice formation from collecting upon and subsequently extracting a pile as a result of a variation of tide level, which comprises: guard means concentrically mounted to and axially extending along said pile, said guard means being tapered such that the diameter of said guard means decreases in an upward direction to thereby allow said ice formation to be vertically displaced relative to said guard means during said tide level variation whereby said ice formation is prevented from extracting said pile during said tide level variation; means for firmly securing said guard means to said pile; and stiffening means connected to said guard means at a plurality of points along the length of said guard means and located between and interconnecting said guard means and said pile wherein said stiffening means comprises; only a plurality of horizontal stiffening rings connected with said guard means; and a plurality of vertical fin members connected to said guard means and interconnecting said horizontal stiffening rings.
Claim 2
Dependent Claim
167 words
A pile protection for preventing an ice formation from collecting upon and subsequently extracting a pile as a result of a variation of tide level, which comprises: guard means concentrically mounted to and axially extending along said pile, said guard means being tapered such that the diameter of said guard means decreases in an upward direction to thereby allow said ice formation to be vertically displaced relative to said guard means during said tide level variation whereby said ice formation is prevented from extracting said pile during said tide level variation; means for firmly securing said guard means to said pile; and stiffening means connected to said guard means at a plurality of points along the length of said guard means and located between and interconnecting said guard means and said pile wherein said stiffening means comprises; only a plurality of horizontal stiffening rings connected with said guard means; and a plurality of vertical fin members connected to said guard means and interconnecting said horizontal stiffening rings.
Claim 3
Dependent Claim
23 words
The pile protection device as set forth in claim 1 wherein said horizontal stiffening rings are unitarily moldably connected to said guard means.
Claim 4
Dependent Claim
26 words
The pile protection device as set forth in claim 1 wherein each of said horizontal stiffening rings include deformably tapered end portions for engaging said pile.
Claim 5
Dependent Claim
26 words
The pile protection device as set forth in claim 1 which further comprises joint means for interconnecting corresponding end portions of said one piece guard means.
Claim 6
Dependent Claim
112 words
A pile protection device for preventing an ice formation from collecting on and subsequently extracting a pile as a result of variation of tide level which comprises: guard means concentrically mounted to and axially extending along said pile, said guard means being tapered such that the diameter of said guard means decreases in an upward direction to thereby allow said ice formation to be vertically displaced relative to said guard means during said tide level variation whereby said ice formation is prevented from extracting said pile during said tide level variation; and means for firmly engaging said guard means to said pile wherein said guard means comprises a plurality of tapered strips.
Claim 7
Dependent Claim
112 words
A pile protection device for preventing an ice formation from collecting on and subsequently extracting a pile as a result of variation of tide level which comprises: guard means concentrically mounted to and axially extending along said pile, said guard means being tapered such that the diameter of said guard means decreases in an upward direction to thereby allow said ice formation to be vertically displaced relative to said guard means during said tide level variation whereby said ice formation is prevented from extracting said pile during said tide level variation; and means for firmly engaging said guard means to said pile wherein said guard means comprises a plurality of tapered strips.
Claim 8
Dependent Claim
28 words
The pile protection device as set forth in claim 5, wherein said guard means further comprises a jacket member mounted on the circumferential surface of said tapered strips.
Claim 9
Dependent Claim
113 words
A pile protection device for preventing an ice formation from collecting on and subsequently extracting a pile as a result of variation of tide level, which comprises: guard means concentrically mounted to and axially extending along said pile, said guard means being tapered such that the diameter of said guard means decreases in an upward direction to thereby allow said ice formation to be vertically displaced relative to said guard means during said tide level variation whereby said ice formation is prevented from extracting said pile during said tide level variation; and means for firmly securing said guard means to said pile wherein said guard means comprises a series of interconnected curved sections.
Claim 10
Dependent Claim
113 words
A pile protection device for preventing an ice formation from collecting on and subsequently extracting a pile as a result of variation of tide level, which comprises: guard means concentrically mounted to and axially extending along said pile, said guard means being tapered such that the diameter of said guard means decreases in an upward direction to thereby allow said ice formation to be vertically displaced relative to said guard means during said tide level variation whereby said ice formation is prevented from extracting said pile during said tide level variation; and means for firmly securing said guard means to said pile wherein said guard means comprises a series of interconnected curved sections.
Claim 11
Dependent Claim
113 words
A pile protection device for preventing an ice formation from collecting on and subsequently extracting a pile as a result of variation of tide level, which comprises: guard means concentrically mounted to and axially extending along said pile, said guard means being tapered such that the diameter of said guard means decreases in an upward direction to thereby allow said ice formation to be vertically displaced relative to said guard means during said tide level variation whereby said ice formation is prevented from extracting said pile during said tide level variation; and means for firmly securing said guard means to said pile wherein said guard means comprises a series of interconnected rectangular ribs.
Claim 12
Dependent Claim
113 words
A pile protection device for preventing an ice formation from collecting on and subsequently extracting a pile as a result of variation of tide level, which comprises: guard means concentrically mounted to and axially extending along said pile, said guard means being tapered such that the diameter of said guard means decreases in an upward direction to thereby allow said ice formation to be vertically displaced relative to said guard means during said tide level variation whereby said ice formation is prevented from extracting said pile during said tide level variation; and means for firmly securing said guard means to said pile wherein said guard means comprises a series of interconnected rectangular ribs.
