Method of connecting pipe pieces via universal joint

A method of connecting a first pipe and a second pipe which are within respective first and second adjacent cylindrical members coupled to each other through a universal joint in such a manner as to be able to swing relative to each other, said universal joint including a first pair of opposed yokes attached to one end of said first cylindrical member, a second pair of opposed yokes attached to an end of said second cylindrical member, and a cross pin pivotally mounted in said first and second pairs of yokes, said cross pin having a first hub, a second hub, a third hub, and a fourth hub;

• said method comprising:
• extending said first pipe through a side wall of said first cylindrical member in parallel with said first hub,
• extending said second pipe through a side wall of said second cylindrical member in parallel with said second hub,
• extending a relay pipe through said first hub to said second hub, said relay pipe having a first end and a second end which project out of its respective hub,
• connecting a first substantially S-shaped rocker pipe through a first swivel joint to an end of said first pipe which extends through said side wall of said first cylindrical member,
• connecting a first substantially U-shaped connecting pipe to said first rocker pipe through a first ball joint and to said first end of said relay pipe through a second ball joint, connecting a second substantially S-shaped rocker pipe through a second swivel joint to an end of said second pipe which extends through said side wall of said second cylindrical member, and
• connecting a second substantially U-shaped connecting pipe to said second rocker pipe through a third ball joint and to said second end of said relay pipe through a fourth ball joint.
