Abstract
Abstract A magnetic conveyer comprising a pair of pulleys, a belt around the pair of pulleys, a plurality of magnetic rail pieces fixedly arranged inside the belt, and a magnet rail extending across the width of the belt and rotatably supported at a supporting point so that it may taken any desirable angle to the axial line of the conveyer.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
142 words
A conveyer assembly for transporting magnetizable objects comprising a pair of spaced pulleys mounted for rotation about generally parallel axes, a conveyer belt extending about said pulleys to be driven therebY along a conveying path in a predetermined direction extending linearly between the said pulleys, magnetic means extending transversely across said path at a location between said pulleys, said magnetic means being arranged to magnetically hold against said belt objects to be transported thereby, and means for adjustably mounted said magnetic means for pivotal motion about an axis extending in a direction perpendicular to both said predetermined conveying direction and said axes of said pulleys, said magnetic means comprising a magnetic rail formed as a generally longitudinal member having a pair of ends, said assembly including means for adjustably mounting said rail for pivotal motion about at least one of said ends.
Claim 2
Dependent Claim
142 words
A conveyer assembly for transporting magnetizable objects comprising a pair of spaced pulleys mounted for rotation about generally parallel axes, a conveyer belt extending about said pulleys to be driven therebY along a conveying path in a predetermined direction extending linearly between the said pulleys, magnetic means extending transversely across said path at a location between said pulleys, said magnetic means being arranged to magnetically hold against said belt objects to be transported thereby, and means for adjustably mounted said magnetic means for pivotal motion about an axis extending in a direction perpendicular to both said predetermined conveying direction and said axes of said pulleys, said magnetic means comprising a magnetic rail formed as a generally longitudinal member having a pair of ends, said assembly including means for adjustably mounting said rail for pivotal motion about at least one of said ends.
Claim 3
Dependent Claim
28 words
An assembly according to claim 1 wherein said magnetic means is positioned at a forward portion of said conveyor belt taken in the direction of said conveying path.
Claim 4
Dependent Claim
41 words
An assembly according to claim 1 further comprising a plurality of magnetic rail pieces located between said pulleys at positions separate from said magnetic rail, and a magnetic plate positioned between said conveyor belt and said plurality of magnetic rail pieces.
