Claim 1
Independent Claim
262 words
A mass cooking device for cooking meat patties and the like comprising: a power driven conveyor belt means having a first dispensing end and a second exiting end and a middle zone defining a patty turnover zone, the conveyor means includes a conveyor belt endlessly rotating between the ends and defining a continuous loop, the belt includes elongated members spaced apart forming a grill thereby when the belt rotates it comprises a moving grill, a pair of aligned ovens being a first and second oven, the first oven adjacent the dispenser end of the conveyor means, the second oven adjacent the exiting end of the conveyor means, both ovens adjacent the middle zone, means for dispensing meat patties on the belt at the dispensing end of conveyor means, a turnover means spaced between the ovens at the middle zone of the conveyor means comprising: a V-shaped spatula having a pair of diverging legs, an upper and a lower leg, each leg comprising finger-like structures, the finger-like structures mating compatibly with the moving grill conveyor belt, the lower leg being normally below the belt, gear means coordinated with the conveyor means and the dispensing means for rotating the patty 180° after being captured by the spatula, thereby the patties having been cooked on one side are reversed onto the other side for cooking by the second oven, compressor means fixedly connected to the conveyor means above and aligned with the second oven for squeezing the meat patties tight against the belt, thereby the patties are compressed to attractive and easy to serve packages.
