Abstract: A tire press unloader for a tire curing press of the upstanding bladder type includes a pivoting tire platform mounted for vertical movement on a horizontally movable unloader frame. The platform includes a pivot control member to keep the same from pivoting during initial upward movement and then require the same to pivot during the final vertical movement. The control member also requires the platform to return to its horizontal position as it starts downwardly. Obstructions in the path of the control member require such pivotal movement. The tire platform is mounted on a pivoting horizontal shaft disposed in vertical slots in the unloader frame and the pivot control member is secured to the shaft for common pivotal movement. When the press is opened and the cured tire has been elevated by the bladder mechanism, the tire platform is positioned beneath the cured tire to support the tire as the bladder is stripped therefrom.

Abstract: A dual cavity tire press having side by side mold sections incorporate vertically extending center mechanisms which include a shaping bladder. The center mechanisms are moved vertically after the press opens while the bladder is within the tire to strip the tire from the bottom mold sections. Vertical movement of the center mechanisms is obtained by a single floating horizontally disposed piston-cylinder assembly which is mounted at the front of the press outside of the base, each end of the piston-cylinder assembly being connected through a lever arrangement to move the respective bead lift posts of the center mechanisms vertically. When the piston-cylinder assembly is pressurized, its entire force is applied simultaneously to each center mechanism to move the same vertically and such force is maintained throughout the vertical height movement of both center mechanisms. By a removable stop or lock, one of the center mechanisms may be made inoperable without affecting the movement and operation of the other.
