Abstract
Mechanism (10) for removably securing a die (22) to the flange (18) of a discharge (14) of a cooker (12) is disclosed including first and second connector rings (30, 56). The first connector ring (30) is rotatably mounted to the flange (18) of the cooker (12) by its securement to C-shaped carrier members (38) rotatably mounted to C-shaped collar members (32) secured to the flange (18). The first connector ring (30) includes a plurality of circumferentially spaced, wedge-shaped teeth (46) extending radially inwardly. The second connector ring (56) is secured to the flange (24) of the die (22) and includes a plurality of circumferentially spaced, wedge-shaped teeth (66) extending radially outward. The second connector ring (56) is axially movable such that the teeth (66) thereof pass axially between the teeth (46) of the first connector ring (30) in an unlocked position. The first connector ring (30) can be rotated by a hydraulic cylinder (52) to a locked position with the teeth (46, 66) of the connector rings (30, 56) axially abutting and camming the flanges (18, 24) of the cooker (12) and the die (22) together to secure the die (22) to the cooker (12).
