ABSTRACT:
A tire manipulating apparatus has a rotatable head and means for raising and lowering the head. Tire gripping means consists of a pair of spaced, parallel tubular housings which are secured to the head in a common plane, and two L-shaped members, each of which has a first arm telescoped in a housing and a second arm, said second arms being inclined with respect to the first arms so that their free ends are coaxial. Linear motors extend and retract the L-shaped members to grip a tire. Opposed tire gripping elements on the free ends of the arms are rotatable about a common axis by coordinately operable power units to turn a tire gripped by the elements.
