ABSTRACT:
A flip-over PCI which includes a rotatable or oscillatable frame having pairs of tire engaging rims mounted thereon, the inner rim of each pair being fixed to the frame on opposite sides thereof and including an axially projecting and axially rotatable lock shaft, the outer rim of each pair including a housing for the lock shaft. The lock shaft and housing are constructed for alignment and safety so that the outer rim cannot rotate with respect to the inner rim and the lock shaft can rotate with respect to the outer rim only when the two rims are adjacent each other when the tire is not inflated. The rotation of the outer rim is precluded by an interference between the two rims when closely adjacent each other and by an interference between the shaft and housing when the rims are separated. One or the other of such interferences is always operative.
