ABSTRACT OF THE DISCLOSURE A tire-changing machine has a frame mounting a wheel rim in a generally horizontal position, an upper bead breaker support column mounted generally vertically in the frame, and an upper bead breaker shoe. The shoe is mounted to the support column so that the shoe extends generally laterally therefrom, the mounting means including a horizontally projecting column lock member having an upper wall and a lower wall spaced from said upper wall. The walls each have a thickness significantly less than the spacing therebetween, and have aligned apertures therein which are slightly larger than a cross section of the support column for receiving the column therethrough. The force applied to the shoe has a force component in either direction parallel to the longitudinal axis or said column urges opposite edges of the aligned apertures to assume high pressure contact with adjacent surfaces on the column providing frictional resistance to movement of the mounting means along the column.
