Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 217 words
A material handling device for a crane mechanism comprising a generally "U" shaped support, connectable to said crane mechanism, a frame also generally "U" shaped and pivot means connected to said frame and support whereby said frame is freely pivoted within said support, securing means on said frame adapted to be inserted through the center of a coil of material, a pair of securing arms within said securing means, actuating mechanism operative to extend said arms whereby said arms can engage an end of the coil for transport of said coil material when said device is connected to said crane mechanism, said pivot means being so designed that said coil can be changed from a vertical to a horizontal position and vice-versa using the weight of the coil, said device including a floor mounted pivoting mechanism including a pair of horizontal and stationary rails pivotally and slidingly supporting a coil cradle, said cradle engaging the surface of the coil and said securing means whereby said pivoting mechanism is usable to change the orientation of said coil from horizontal to vertical and vice-versa without damage to the coil solely by use of gravity and the crane mechanism by cooperation of the free pivot of said frame and the sliding and pivoting mounting of the cradle in said rails.
Claim 2
Dependent Claim 217 words
A material handling device for a crane mechanism comprising a generally "U" shaped support, connectable to said crane mechanism, a frame also generally "U" shaped and pivot means connected to said frame and support whereby said frame is freely pivoted within said support, securing means on said frame adapted to be inserted through the center of a coil of material, a pair of securing arms within said securing means, actuating mechanism operative to extend said arms whereby said arms can engage an end of the coil for transport of said coil material when said device is connected to said crane mechanism, said pivot means being so designed that said coil can be changed from a vertical to a horizontal position and vice-versa using the weight of the coil, said device including a floor mounted pivoting mechanism including a pair of horizontal and stationary rails pivotally and slidingly supporting a coil cradle, said cradle engaging the surface of the coil and said securing means whereby said pivoting mechanism is usable to change the orientation of said coil from horizontal to vertical and vice-versa without damage to the coil solely by use of gravity and the crane mechanism by cooperation of the free pivot of said frame and the sliding and pivoting mounting of the cradle in said rails.
Claim 3
Dependent Claim 51 words
A device as claimed in claim 1 wherein said actuating mechanism includes an electric motor, a rotating member in engagement with said arms and movable by said electric motor to extend or retract said arms and said arms extending and supporting substantially the entire width of the material of said coil.
