Abstract
A doughnut fryer flight conveyor for selectively advancing different size dough forms through the hot oil bath of a doughnut frying machine includes a plurality of primary flights extending between spaced, parallel, endless copnveyor chains and a plurality of secondary flights or pusher bars. The secondary flights are each positioned between adjacent pairs of primary flights. A clutch ring mounts the secondary flights to the conveyor chain so that the flights may be moved to an inoperative position immediately adjacent one of the primary flights to an operative position intermediate the flights. When in the operative position, the doughnut fryer flight conveyor is adapted to advance a smaller size doughnut or dough form through the frying machine.
