Abstract
191,711. Soc. Anon. des Etablissements A. Olier. Jan. 11, 1922, [Convention date]. Vulcanizing, cores for; presses. - In a tyre vulcanizing-press having radially expanding core segments the radial movements are imparted to the segments b y t w o hydraulic jacks arranged laterally, the pistons being coupled so that they move together. Cylinders 1, 2 on either side of the main cylinder 3, have pistons 4, 5 respectively attached to a cross-piece 6 which carries a rod 7 to which are pivoted links 8 actuating the coresegments 8<1>. To ensure uniformity of movement of the pistons 4 and 5, collars 9 are pinned to the pistons and carry pivoted links to 10, Fig. 2, attached to cranks 11 on a rocking shaft 12. On opening the press, the core is lowered on to a plate 14, the height of which may be adjusted by blocks placed on the top of supporting-rods 13.
