ABSTRACT:
A loader for tire machinery such as tire presses is disclosed, which loader is supported from a vertically and horizontally movable frame and which includes a vertical shaft or sleeve journaled with respect to the frame with a horizontal plate secured for rotation therewith. Loader shoes are mounted on the frame for radial movement and respective links interconnect the plate and each loader shoe, each link extending at a common angle with respect to a radius from the center of rotation of the plate, and rotation of the plate in one direction will reduce the angle accordingly moving the shoes radially outwardly and rotation of the plate in the opposite direction will increase the angle moving the shoes radially inwardly. Each link is adjustable in length and the extent of rotation of the plate in one or both directions is limited by adjustable stops. The loader shoes remain parallel throughout their movement and are supported for radial movement by self-aligning slider blocks.
