Apparatus, for fitting and removing an automobile tire, comprising:
- (i) a frame
- (ii) a table rotatably mounted on said frame and including jaws radially movable for gripping a wheel
- (iii) means for rotating said table
- (iv) means for radially moving said jaws
- (v) a column extending vertically from said frame
- (vi) a horizontal arm carried by said column and movable horizontally along its own longitudinal axis with respect to said column,
- (vii) a carriage movable along the arm
- (viii) a vertical bar carried by and vertically adjustable with respect to said carriage, said bar being provided with a tool for fitting and removal of a tire, and
- (ix) fixing means acting between the carriage and the arm, and between the vertical bar and the carriage, for simultaneously locking the carriage to the arm and locking the vertical bar to the carriage such that the tool becomes disposed, in two directions, at a predetermined distance from a wheel on said table, said fixing means comprising first and second relatively movable blocks included in said carriage and disposed one at each side of the arm and each defining a longitudinal guide for the arm, the guide defined by one said block being formed to provide a clearance in height of the block with respect to the arm, said one block having a vertical opening receiving the bar in contact with the arm, a shaft connecting the two blocks, and actuating means which serve to simultaneously draw the two blocks together to press the bar against the arm, and to raise said one block with respect to the other block for locking said one block to the arm with the bar in a predetermined position with respect to the arm.
