A compact double Cardan motion universal joint has a substantially cylindrical housing having an input end and an output end, with an input shaft and ball joint and an output shaft and interengaging ball joint, respectively; each ball joint consisting of a substantially spherical ball on the shaft member, a ball seat torsionally fixed in the housing, and pivots for providing articulation of the ball shaft about two orthogonal axes. Interengagement between the ball joints is provided by an interconnection ball joint consisting of a hollow socket on a joining end of one of the spherical ball shaft members of said universal joint, and a spherical ball on a joining end of the other spherical ball shaft member, the interconnection ball joint providing universal pivoting and translating motion at a juncture between interengaging portions of the ball shaft members. Pivoting and translating motion between the interengaging portions of said ball shaft members is limited, such that the input shaft and output shaft maintain substantially equal angles with the housing.

Ball and socket double cardan motion universal joint

Apparatus and method for lifting the top coil from a stack of coils. The apparatus includes a housing which is to be attached to the forks of the fork lift truck and a hook suspended from the housing wherein the hook is adapted to facilitate removal of a coil from a stack and its subsequent transport. The method involves the steps of offsetting a top coil from a stack of coils so as to position a portion of its inner core to overhang the cores of the remaining coils in the stack, and thereafter engaging such overhanging portion of the top coil to lift it from the stack and transport it to a desired location.
