Abstract
Abstract A clamping device for an internally separating circular saw blade comprising means for clamping the outer edge of the saw blade and an annular fluid-tight pressure chamber having a peripheral edge portion located intermediate the clamped edge portions of the blade and substantially adjacent the blade, said pressure chamber being adapted to receive a fluid medium under pressure such that at least a portion of the blade of the saw is displaced thereby out of its axial plane.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
108 words
A clamping device for an internally separating circular saw blade, comprising means for clamping the outer edge of the saw blade and an annular fluid - tight pressure chamber having a peripheral edge portion located intermediate the clamped edge portions of the blade and substantially adjacent the blade, said pressure chamber being adapted to receive a fluid medium under pressure such that at least a portion of the blade of the saw is displaced thereby out of its axial plane, and said means for clamping said outer edge of said saw blade comprising two rings, said rings being interconnected externally of said outer edge of said saw blade.
Claim 2
Dependent Claim
108 words
A clamping device for an internally separating circular saw blade, comprising means for clamping the outer edge of the saw blade and an annular fluid - tight pressure chamber having a peripheral edge portion located intermediate the clamped edge portions of the blade and substantially adjacent the blade, said pressure chamber being adapted to receive a fluid medium under pressure such that at least a portion of the blade of the saw is displaced thereby out of its axial plane, and said means for clamping said outer edge of said saw blade comprising two rings, said rings being interconnected externally of said outer edge of said saw blade.
Claim 3
Dependent Claim
50 words
A clamping device as defined in claim 1 wherein one said ring is provided with wall portions defining an annular groove of rectangular cross-section, a protective ring of a soft material being located in said groove, said annular groove being adapted to receive said displaced portion of said saw blade.
Claim 4
Dependent Claim
134 words
A clamping device for an internally Separating saw blade, comprising means for clamping the outer edge of said saw blade consisting of two rings, said rings being interconnected externally of said outer edge of said saw blade, one said ring having wall portions defining an annular channel of rectangular cross-section, an annular fluid-tight pressure chamber having a pheripheral edge portion located intermediate the clamped edge portions of the blade and located substantially adjacent said blade such that at least a portion of said blade is displaced thereby out of its axial plane and means for controlling the amount of displacement of said blade said means constituted by a pressure ring located on the opposed side of said blade to said pressure chambers wherein said pressure ring is slidably displaceably located in said annular groove.
Claim 5
Dependent Claim
134 words
A clamping device for an internally Separating saw blade, comprising means for clamping the outer edge of said saw blade consisting of two rings, said rings being interconnected externally of said outer edge of said saw blade, one said ring having wall portions defining an annular channel of rectangular cross-section, an annular fluid-tight pressure chamber having a pheripheral edge portion located intermediate the clamped edge portions of the blade and located substantially adjacent said blade such that at least a portion of said blade is displaced thereby out of its axial plane and means for controlling the amount of displacement of said blade said means constituted by a pressure ring located on the opposed side of said blade to said pressure chambers wherein said pressure ring is slidably displaceably located in said annular groove.
Claim 6
Dependent Claim
24 words
A clamping device as defined in claim 3 wherein, said pressure ring being adapted to be moved against said blade by independantly adjustable screws.
