Rollers mountable to a cooling bed plate transfer grid

A cooling bed plate transfer grid comprising a plurality of elongate parallel members having upper edges respectively for effecting movement of plates being cooled, at least one roller, an axle for said roller, a pair of blocks for receiving ends respectively of said axle, a pair of cutouts in said upper edges of a pair of said parallel members for receiving said blocks respectively with said roller received between and projecting above said parallel members for engaging the plates as they move along the grid, a clamp for clamping each of said blocks in said respective cutout, and means for preventing axial movement of said roller.

A cooling bed plate transfer grid comprising a plurality of elongate parallel members having upper edges respectively for effecting movement of plates being cooled, at least one pair of cutouts, each having forward and aft edges, in said upper edges of a pair of said parallel members for receiving end portions respectively of an axle for a roller to be received between and to project above said pair of parallel members for engaging the plates as the plates move along the grid, means for clamping an axle end portion in each of said cutouts, said clamping means comprising slots in said forward and aft edges respectively for receiving a plate with a respective axle end portion received below the clamping plate.

Apparatus comprising a plurality of elongate parallel members having upper edges respectively, at least one roller, an axle for said roller, a pair of blocks for receiving ends respectively of said axle, a pair of cutouts, each having forward and aft edges, in said upper edges of a pair of said parallel members for receiving said blocks respectively with said roller received between and projecting above said parallel members, and a clamp for clamping each of said blocks in said respective cutout, said clamp comprising a plate and further comprising a pair of slots in said forward and aft edges respectively for receiving said clamping plate with said respective block received below said clamping plate.

A cooling bed plate transfer grid comprising a plurality of elongate parallel members having upper edges respectively for effecting movement of plates being cooled, at least one roller, an axle for said roller, a pair of bearings for said axle, means defining a pair of cutouts in said upper edges of a pair of said parallel members for receiving said bearing respectively with said roller received between and projecting above said parallel members for engaging the plates as they are moved along the grid, and each of said bearings being formed to be invertible so that a top and a bottom thereof may be interchanged.

A roller insert for a cooling bed plate transfer grid having a plurality of elongate parallel members for effecting movement of plates being cooled, the insert comprising a roller, an axle for said roller, a pair of blocks, said blocks shaped to be received in a pair of cutouts respectively in upper edges of a pair of the parallel members with said roller received between and projecting above the parallel members for engaging the plates as they are moved along the grid, each of said blocks having an aperture for receiving said axle and having a geometric center in a plane normal to said axle, said aperture having a geometric center in a plane normal to said axle, wherein said center of said aperture is offset from said center of said block.

A cooling bed plate transfer grid comprising a plurality of elongate parallel members for effecting movement of plates being cooled and further comprising an insert including a roller, an axle for said roller, and a pair of blocks, each said block received in a pair of cutouts respectively in upper edges of a pair of the parallel members with said roller received between and projecting above the parallel members for engaging the plates as they are moved along the grid, each of said blocks having an aperture in which is received said axle and having a geometric center in a plane normal to said axle, said aperture having a geometric center in a plane normal to said axle, wherein said center of said aperture is offset from said center of said block.
