The activating mechanism includes a fluid pressure cylinder which moves the drip trays between open and closed positions. The activating mechanism includes a linkage which moves into a locking position when the pressurized cylinder moves the trays into the closed position to automatically maintain the drip trays in the closed position even though pressure to the activating cylinder is relieved.
