ABSTRACT:
A cooker for continuous grilling of hamburger patties and the like uses a shiftable grid which intermittently lifts the patties off a stationary grid and effects advancement after each lift-off until a U-shaped path is traversed extending initially through and terminating beyond one end of the cooker exteriorly thereof. The patties travel upwardly along a straight line with respect to a first pair of legs of the grids and then upwardly and arcuately with respect to a pair of first grid quadrants, whereupon they invert and drop such as to travel upwardly and arcuately with respect to a pair of second grid quadrants. Finally, the patties travel upwardly along a straight line with respect to a pair of legs of the grids forming the final stretch of the travel.
