DISCONTINUOUS OVEN

摘要

In a rack oven in which the rack can be pushed into the oven chamber and gripped and rotated or reciprocated by a driver member at the top of the oven chamber, the driver member is shiftable between a lower position for gripping the rack with the latter supported by the floor of the oven chamber and an upper position for holding the rack raised from the floor. The shifting of the rack is effected by means of an axial cam or a toggle linkage and is controlled by the opening and closing movements of the door of the oven chamber.
