Abstract
Abstract A support unit, for a mobile belt conveyor, having multiple belt supporting idlers with some of the idlers mounted on swing brackets controlled by the relative angular positioning of successive support units to provide idler end locations to produce curved belt edges and controlled horizontal belt curvature as a result of moving the conveyor along a curved path.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
113 words
A conveyor train comprising: a series of support sections having portions cooperable to support a horizontally flexible conveyor belt to permit conveying of material along a generally horizontal elongated path; said support sections pivotally connected and relatively movable to vary the configuration of said path; adjacent portions of at least certain ones of said support sections having belt supporting means carried thereby and means mounting said belt supporting means for movement transversely and horizontally of said path; and connecting means connecting said adjacent sections and said belt supporting means to move said belt supporting means in said transverse and horizontal manner upon said relative movement of said certain ones of said support sections.
Claim 2
Dependent Claim
113 words
A conveyor train comprising: a series of support sections having portions cooperable to support a horizontally flexible conveyor belt to permit conveying of material along a generally horizontal elongated path; said support sections pivotally connected and relatively movable to vary the configuration of said path; adjacent portions of at least certain ones of said support sections having belt supporting means carried thereby and means mounting said belt supporting means for movement transversely and horizontally of said path; and connecting means connecting said adjacent sections and said belt supporting means to move said belt supporting means in said transverse and horizontal manner upon said relative movement of said certain ones of said support sections.
Claim 3
Dependent Claim
20 words
A conveyor train as specified in claim 1 wherein each of said belt supporting means includes roller sets mounted thereon.
Claim 4
Dependent Claim
46 words
A conveyor train as specified in claim 2 wherein a horizontally flexible conveyor belt is supported by said roller sets and said roller sets includes means to control both edges of said belt at all angles of deviation of said support sections relative to each other.
Claim 5
Dependent Claim
20 words
A conveyor train as specified in claim 1 wherein said support sections include a plurality of ground engaging mobile means.
Claim 6
Dependent Claim
41 words
A conveyor train as specified in claim 2 wherein said roller sets are supported above said support sections and additionally including other roller sets, with each of said other roller sets being supported below the upper surface of said support sections.
Claim 7
Dependent Claim
25 words
A conveyor train as specified in claim 1 wherein each of said certain ones of Said sections rigidly and nonmovably support other belt supporting means.
Claim 8
Dependent Claim
27 words
A conveyor train as specified in claim 1 wherein said connecting means include non-extensible rigid link means extending between said belt supporting means and said adjacent portions.
Claim 9
Dependent Claim
39 words
A conveyor train as specified in claim 3 additionally including limiting means which limit the relative movement of adjacent pairs of said support sections to each other to a preselected maximum number of degrees of deviation from straight alignment.
Claim 10
Dependent Claim
46 words
A conveyor train as specified in claim 3 wherein said pivotally supported roller sets on said adjacent portions are horizontally pivoted by said pivot means at all degrees of curvature of said path to maintain uniform curvature of a conveyor belt supported by said support sections.
Claim 11
Dependent Claim
22 words
A conveyor train as specified in claim 3 wherein the pivot axis of said supporting means are substantially normal to said path.
Claim 12
Dependent Claim
50 words
A conveyor train as specified in claim 3 wherein when one of said support sections is displaced from the support section adjacent thereto in one horizontal direction the supporting means carried by said one of said support sections at said adjacent portion thereof is pivoted in the opposite horizontal direction.
Claim 13
Dependent Claim
34 words
A conveyor train as specified in claim 5 wherein said roller support and guide the top run of a conveyor belt and said other roller sets guide the bottom run of a conveyor belt.
Claim 14
Dependent Claim
89 words
A conveyor train adapted to support the upper run of a conveyor belt thereon comprising: support sections having means rendering said support sections relatively movable along a selectively variable curvalinear axis; end portions of at least certain of said support sections having horizontally movable belt supporting means carried thereon; and connecting means connecting said supporting means on one of said sections and the end section of said support section adjacent thereto to horizontally move said supporting means upon horizontal movement of said latter mentioned sections relative to each other.
Claim 15
Dependent Claim
89 words
A conveyor train adapted to support the upper run of a conveyor belt thereon comprising: support sections having means rendering said support sections relatively movable along a selectively variable curvalinear axis; end portions of at least certain of said support sections having horizontally movable belt supporting means carried thereon; and connecting means connecting said supporting means on one of said sections and the end section of said support section adjacent thereto to horizontally move said supporting means upon horizontal movement of said latter mentioned sections relative to each other.
