A motor driven assembly to assist in the raising and lowering of the lid of the vat of a large capacity pressure cooker. The assist assembly comprises a vertically oriented support frame secured to the rear of the pressure cooker housing. The support frame comprises a pair of vertical, inwardly opening, U-shaped guide rails joined together by top and bottom horizontal support frame members. The front, rear, sides and top of the support frame are enclosed by panel members completing the overall housing of the pressure cooker. A vertically oriented, frame-like carriage is mounted within the support frame. The carriage has rollers received within the support frame guide rails and is vertically shiftable within the support frame. The carriage mounts a pair of horizontal arms which extend through vertical slots in the pressure cooker housing and which support the vat lid. The top frame member of the support frame carries a drum which is driven by an electric motor. At least one cable has one of its ends attached to the drum and the other of its ends attached to the carriage, enabling the motor and drum to raise and lower the carriage within the frame, thereby shifting the vat lid between open and closed positions.
