Salvaged Nautical Foundry Pattern, Industrial Shipbuilding Mold, Power Housing

This industrial, wooden foundry pattern was designed and manufactured by Sun Shipbuilding & Drydock Company in Pennsylvania. We later salvaged it from a nautical collector's warehouse in New Jersey. The handmade wooden pattern is 29" wide with a vivid paint scheme and interesting, finned, hydrodynamic shape. Perhaps it was the pattern for the housing around a moving engine part. The manufacturer's name, part name and number are hand painted on the corner of the base plate reading, "S.S.B.Co", with "G23-783-100".

Manufacturer's History:
Sun Shipbuilding & Drydock Company was a major shipbuilding company in operation from 1917–1989 in Chester, Pennsylvania on the Delaware River. Sun Shipbuilding launched its first ship in 1917, just as the United States was entering World War I. By the start of World War II, Sun was among the country's five largest shipyards, with eight slipways. At its peak, the company employed more than 40,000 workers at four shipyards, and was the largest private-sector employer of African-Americans in the United States. During the war, Sun built tankers, hospital ships, cargo ships, and escort carriers for the United States Maritime Commission

In 2017, this foundry pattern was salvaged from a nautical warehouse in New Jersey. The pick was featured in Season 9, Episode 8 of the DIY Network show, "Salvage Dawgs".

About the use of Nautical Foundry Molds:
This wooden pattern was used in the process of sand casting. Molding material, such as sand, would be packed around this pattern inside of a casting flask. The sand is then compressed in a process known as ramming. When the molding material reaches the proper density, the pattern is removed. Molten metal is then poured into the cavity created by the positive mold. Once the metal has cooled and hardened, the sand is then broken away and the metal casting is removed. This pattern was used to cast a part of a ship or nautical component.
