Abstract: A mechanism for transmitting force produced by a cylinder includes fulcra (5) and linkages (22) pivotally connected at one of their ends to the fulcra (5). The linkages (22) are pivotally connected at the other of their ends to an anchor block (15). The cylinder is pivotally mounted on the anchor block (15). The anchor block (15) moves on rollers (22) along tram guides (11) during the work stroke of the cylinder. The tram guides (11) have slots through which pivotal connecting means (18) extend. The pivotal connecting means (18) are connected to the one end of the linkages (22).
