An improvement in briquetting presses and the like comprises a wear ring, a press cone, an end tube and a press cylinder which is diametrically slotted and encloses the press cone and the end tube, said parts being secured to a machine frame. To facilitate the dismounting of the abovementioned parts the press cylinder is suspended in a pair of brackets which project from the machine frame in such a way that the press cylinder together with the press cone and the end tube is displaceable away from the machine frame and after such displacement is rotatable on an axis which is substantially perpendicular to the central axis of the press cone and the end tube. A hydraulic jack associated with the press and designed to cooperate with the press cylinder comprises a yoke and a bail which together enclose the press cylinder at the compression of its two slots. To permit the jack to be utilized for pressing out the press cone and the end tube of the press cylinder, the yoke and the bail are rotatable at least about 90 DEG mutually on an axis which at the compression of the slots is located substantially in one of the diametral planes of the press cylinder, and in addition hereto the jack is provided with engagement means cooperating with abutment or holding on means which are provided on the press cylinder. |
