Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
192 words
A conveyor belt cradle assembly for supporting a conveyor belt under a loading zone and above a mounting surface, said conveyor belt having a direction of travel, said cradle assembly comprising: a support member; a pair of wing-like support subassemblies mounted on said support member, each said subassembly having an elongate cross-member, supported on each of its opposing ends by its respective said support subassembly, said cross-member being adapted to support a conveyor belt slidingly positioned thereon, said cross-member being oriented at an inclined angle to said support member such that an outboard portion of each said cross-member is at a higher elevation than an inboard portion thereof; one of said support subassemblies being removably mounted to said support member, allowing said subassembly to be removed from said support member, an association of said support member with said subassemblies constituting a generally "U"-shaped structure suitable for supporting a conveyor belt in a generally "U"-shaped orientation; wherein said support member is adapted to be slidably displaceable on said mounting surface, said cradle assembly being dipslaceable laterally of said conveyor belt's direction of travel upon removal of said detachable subasembly from said support member.
Claim 2
Dependent Claim
192 words
A conveyor belt cradle assembly for supporting a conveyor belt under a loading zone and above a mounting surface, said conveyor belt having a direction of travel, said cradle assembly comprising: a support member; a pair of wing-like support subassemblies mounted on said support member, each said subassembly having an elongate cross-member, supported on each of its opposing ends by its respective said support subassembly, said cross-member being adapted to support a conveyor belt slidingly positioned thereon, said cross-member being oriented at an inclined angle to said support member such that an outboard portion of each said cross-member is at a higher elevation than an inboard portion thereof; one of said support subassemblies being removably mounted to said support member, allowing said subassembly to be removed from said support member, an association of said support member with said subassemblies constituting a generally "U"-shaped structure suitable for supporting a conveyor belt in a generally "U"-shaped orientation; wherein said support member is adapted to be slidably displaceable on said mounting surface, said cradle assembly being dipslaceable laterally of said conveyor belt's direction of travel upon removal of said detachable subasembly from said support member.
Claim 3
Dependent Claim
20 words
The cradle assembly according to claim 1 wherein at least one said support assembly is mounted to said support member.
Claim 4
Dependent Claim
50 words
The cradle assembly according to claim 1 wherein each of said cross-members is fitted with at least one elongate impact bar to define a sliding surface for said conveyor belt, a longitudinal axis of each said impact bar being oriented parallel to said direction of travel of said conveyor belt.
Claim 5
Dependent Claim
166 words
A conveyor belt cradle assembly for use in supporting a conveyor belt in a loading zone and above a mounting surface, said conveyor belt having a direction of travel, said cradle assembly comprising: a support member; at least one support subassembly removably mounted on said support member, said at least one support subassembly including an elongate cross-member, said cross-member having opposite ends, each of said ends being mounted on and supported by said cross-member's respective said subassembly, residing at an inclined angle to said support member such that an outboard portion said cross-member is at a higher elevation than an inboard portion thereof, an association of said support member and said at least one support subassembly constituting a structure suitable for supporting a conveyor belt in a non-planar orientation; wherein said support member is adapted to be slidably displacable on said mounting surface, said cradle assembly being dipslaceable laterally of said conveyor belt's direction of travel upon removal of said detachable subasembly from said support member.
Claim 6
Dependent Claim
166 words
A conveyor belt cradle assembly for use in supporting a conveyor belt in a loading zone and above a mounting surface, said conveyor belt having a direction of travel, said cradle assembly comprising: a support member; at least one support subassembly removably mounted on said support member, said at least one support subassembly including an elongate cross-member, said cross-member having opposite ends, each of said ends being mounted on and supported by said cross-member's respective said subassembly, residing at an inclined angle to said support member such that an outboard portion said cross-member is at a higher elevation than an inboard portion thereof, an association of said support member and said at least one support subassembly constituting a structure suitable for supporting a conveyor belt in a non-planar orientation; wherein said support member is adapted to be slidably displacable on said mounting surface, said cradle assembly being dipslaceable laterally of said conveyor belt's direction of travel upon removal of said detachable subasembly from said support member.
Claim 7
Dependent Claim
194 words
A conveyor belt cradle assembly for supporting a conveyor belt in a loading zone, said conveyor belt having a direction travel, said cradle assembly comprising: an elongate base support positioned substantially orthogonal to said direction of travel; a pair of upright supports mounted spacedly apart from one another on said base support; a pair of horizontal supports mounted spacedly apart from one another on said base support, each horizontal support being mounted on a respective said upright support; a pair of angulated supports, each angulated support having a first end mounted on and supported by a respective upright support, and a second opposing end mounted on and supported by a respective horizontal support wherein a support subassembly formed by a respective horizontal support, upright support and angulated support form a triangle-shaped structure; and a plurality of elongate impact bars mounted on said angulated supports, a longitudinal axis of each said impact bar being oriented to extend parallel said direction of travel; wherein one of said support subassemblies are spacedly mounted on said base support to define a generally "U"-shaped structure; and wherein one of said support subassemblies is removably mounted to said base support.
Claim 8
Dependent Claim
194 words
A conveyor belt cradle assembly for supporting a conveyor belt in a loading zone, said conveyor belt having a direction travel, said cradle assembly comprising: an elongate base support positioned substantially orthogonal to said direction of travel; a pair of upright supports mounted spacedly apart from one another on said base support; a pair of horizontal supports mounted spacedly apart from one another on said base support, each horizontal support being mounted on a respective said upright support; a pair of angulated supports, each angulated support having a first end mounted on and supported by a respective upright support, and a second opposing end mounted on and supported by a respective horizontal support wherein a support subassembly formed by a respective horizontal support, upright support and angulated support form a triangle-shaped structure; and a plurality of elongate impact bars mounted on said angulated supports, a longitudinal axis of each said impact bar being oriented to extend parallel said direction of travel; wherein one of said support subassemblies are spacedly mounted on said base support to define a generally "U"-shaped structure; and wherein one of said support subassemblies is removably mounted to said base support.
