Abstract: A cooking machine includes a housing having side walls with doors that can be raised and lowered to vent the cooking chamber defined within the housing. A latching member is pivotally mounted on a channel member guiding the doors, and can be pivoted manually into a position in which it engages the bottom surface of the door thereby retaining the door in the upward most position. When the door is to be lowered, the latching member is pivoted to a position by gravity which pivots the latching member out of the line of travel of the door. The door can then be lowered to the lowered position.
