Title: Innovations by David A Fort
Introduction
David A Fort is an accomplished inventor based in Spokane, WA (US). He holds three patents, showcasing his contributions to the field of metal casting technology. His innovative designs have significantly impacted the efficiency and effectiveness of casting processes.
Latest Patents
One of his latest patents is the Annular Metal Casting Unit. This invention reverses previous practices by placing the annular case at the bottom of the mold rather than at the top. The case is designed to be relatively thick axially, forming a substantial portion of the mold body at the outer periphery. At the top, an annular plate creates flanges that allow the unit to be lowered into a casting table from above. This design supports the unit on the table while defining the lower end opening of the mold cavity. Additionally, it includes an outlet for liquid coolant that is discharged onto the molten metal as it emerges from the unit. The case is typically monolithic and features an annular sump covered by the plate, forming a chamber for coolant. A graphite casting ring may line the inner periphery, while a refractory top ring forms a hot top for the cavity.
Another significant invention is a Metal Casting Unit, which consists of a monolithic body that is annular in shape. This unit features an outturned annular flange and a set of lugs that are angularly spaced about the axis. The design includes a circumferential groove with mullions that create ports, interconnected with the cavity in the lower end portion. The unit is designed to be supported in a metal casting table, with liquid coolant discharge means surrounding it. A device is also included to sense leakage between the casting unit and the chamber, ensuring efficient operation.
