Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
142 words
In a curved wear lining for a curved surface facing the center of curvature of the type including a layer of wear rubber rigidly combined with a support plate and with a wearing surface facing said center of curvature and means included in the layer of wear rubber and increasing the wear resistance of the wear lining, the improvement wherein said means comprise metal pins arranged within the layer of wear rubber in one or more reciprocally separated layers and spaced from each other, which pins are oriented in radial planes extending from the center of curvature and at least across the wear surface, said layer of rubber being in compression with the compression increasing from the support surface towards the wear surface as a result of bending of the wear lining from a substantially plane state to the intended curved shape.
Claim 2
Dependent Claim
142 words
In a curved wear lining for a curved surface facing the center of curvature of the type including a layer of wear rubber rigidly combined with a support plate and with a wearing surface facing said center of curvature and means included in the layer of wear rubber and increasing the wear resistance of the wear lining, the improvement wherein said means comprise metal pins arranged within the layer of wear rubber in one or more reciprocally separated layers and spaced from each other, which pins are oriented in radial planes extending from the center of curvature and at least across the wear surface, said layer of rubber being in compression with the compression increasing from the support surface towards the wear surface as a result of bending of the wear lining from a substantially plane state to the intended curved shape.
Claim 3
Dependent Claim
44 words
The wear lining as claimed in claim 1, comprising a plurality of layers of pins, characterized in that the distance between the pins in each layer is greater than half the thickness of the pins and less than the threefold thickness of the pins.
Claim 4
Dependent Claim
20 words
The wear lining as claimed in claim 1 or 2, characterized in that the pins have a round cross section.
Claim 5
Dependent Claim
28 words
The wear lining as claimed in claim 1 characterized in that the layer of pins is located more closely to the wear surface than to the support plate.
Claim 6
Dependent Claim
29 words
The wear lining as claimed in claim 1 comprising more than one layer of pins, characterized in that the pins in adjacent layers are displaced relative to each other.
Claim 7
Dependent Claim
29 words
The wear lining as claimed in claim 1, characterized in that at least the layer of pins located closest to the wear surface is parallel to the wear surface.
Claim 8
Dependent Claim
33 words
The wear lining as claimed in claim 1, characterized in that all the layers of pins without the layer or layers located closest to the wear surface are parallel to the support plate.
Claim 9
Dependent Claim
26 words
The wear lining as claimed in claim 1, characterized in that all the layers of pins are parallel to each other and to the wear surface.
Claim 10
Dependent Claim
14 words
A wear lining as in claim 1 wherein said pins have a square cross-section.
Claim 11
Dependent Claim
14 words
A wear lining as in claim 1 wherein said pins have an oval cross-section.
Claim 12
Dependent Claim
75 words
A wear lining comprising: a layer of wear rubber bonded to a bendable support plate, said layer and plate lying in a given plane and having a longitudinal dimension and a transverse dimension; and a plurality of spaced-apart parallel pins completely embedded in said layer, said pins being parallel to a plane which is transverse to and perpendicular to said longitudinal dimension, each of said pins having a length substantially less than said transverse dimension.
Claim 13
Dependent Claim
75 words
A wear lining comprising: a layer of wear rubber bonded to a bendable support plate, said layer and plate lying in a given plane and having a longitudinal dimension and a transverse dimension; and a plurality of spaced-apart parallel pins completely embedded in said layer, said pins being parallel to a plane which is transverse to and perpendicular to said longitudinal dimension, each of said pins having a length substantially less than said transverse dimension.
Claim 14
Dependent Claim
29 words
A wear lining as in claim 11 curved such that it is concave about a center of curvature whereby the rubber facing said center of curvature is in compression.
