Abstract: Tire removal machine with manually or automatically positionable turret comprising a casing supporting a rotatable plate provided with self-centering jaws; a vertical column rising to the side of the plate; a shaft slidable horizontally relative to the column and lockable in position; a sleeve rigid with said shaft and within which the tool holder turret slides vertically, said turret being associated with a spring which maintains the turret spaced from said plate; pneumatic means for locking said shaft and said turret in position; and turret operating and locking means controlled independently by two three-way slide valves which can be switched between an active position in which the compressed air feed line communicates with the delivery lines of said turret operating and locking means, and an inactive position in which said delivery lines are connected to a discharge line respectively, said two slide valves being both associated with a single trigger the operation of which switches them into their inactive

Abstract: A bead release unit comprises an arm (1) which at one end carries a bead ease tool consisting of a curved plate body, whereas at its other end it is intended to be hinged to a supporting structure so that it can rotate between two positions in which it positions said tool respectively distant from and in contact with the tire of a wheel (wheel rim+tire) resting against a locator. The tool (6) is supported by said arm (1) by way of an articulated joint comprising two coplanar pins (8), (9) connected together, of which the first (8) is arranged transverse to the generating lines of said tool to enable this latter to rotate within a plane perpendicular to the plane of rotation of the arm (1), whereas the second (9) is substantially parallel to the generating lines of the tool to enable this latter to rotate within a plane transverse both to the plane of rotation of the arm and to the plane of rotation of the tool about said first pin.

Abstract: A device for automatically locking motor vehicle wheels on to balancing mines in general comprises a traction shaft inserted into and rotating rigidly with a hollow balancing shaft, and of which one end is connected axially to the piston of a cylinder-piston unit while its other end is provided with locking means for the support members of the wheels to be balanced.
