Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
110 words
A chain conveyor of the type having a flexible chain of articulated segments for curving movement in horizontal and vertical planes and having a plurality of platforms connected, respectively, to said segments, said conveyor having means to guide said flexible chain along a path, said platforms each having a surface to receive metallic articles to be conveyed, each of said surfaces lying in a plane extending in the direction of movement of the segment to which the platform is connected, the improvement comprising a flexible magnet having a substantially planar surface mounted on each of said platforms to attract said metallic articles for conveyance along the path of said chain.
Claim 2
Dependent Claim
