Abstract: A device and method for cleaning and inspecting castings is provided. A grind and wash station having a grinder for grinding the casting, and a wash assembly for washing the casting is provided. After the grinding and washing, the casting is transported from the grind and wash station to a borescope station. The borescope station includes a borescope for generating an enlarged image of the interior of the casting, and a monitor for displaying the image.

Abstract: An intermittently moving gondola-type conveyor for handling pallet-supported foundry sand molds includes stations along the curvilinear path of said conveyor where(1) each freshly made mold is invested with a weighted jacket;(2) each jacketed mold is moved to a position to receive molten metal;(3) each of said metal-filled molds is moved through a cooling zone;(4) at the end of said cooling zone, the weighted jacket is removed and transferred to an on-coming freshly made mold, and(5) said cooled metal casting and its surrounding unjacketed sand mold is subsequently discharged said conveyor; each gondola being movably suspended from an overhead curvilinear post-supported upper track, and stabilized against lateral swinging by movable attachments to a lower parallel track also supported by the vertical posts.

Abstract: A foundry mold jacket to be positioned around a sand mold during pouring of the molten metal. The jacket has a generally rectangular body portion having a central opening to receive the sand mold. The jacket has a depth of approximately six inches and straddles the parting line of the mold. Extensions or lugs extend outwardly from opposite sides of the body portion and locating members are disposed on the upper surfaces of the extensions for positioning a weight on the upper surface of the jacket body. In addition, the extensions are provided with locating holes which receive locating pins on lifting arms that raise and lower the mold jacket relative to the sand mold.

Abstract: A cupola charge material in briquette form composed of 15% to 35% by weight of coke breeze, 0% to 25% of iron oxide, 8% to 20% of cement as a binder, and the balance ferrous metal scrap. The ingredients are mixed with water, poured into a mold of the desired shape and dried to set the cement. The resulting briquette has a density greater than 100 pounds per cubic foot.

Abstract: A grinding fixture for grinding cylinder head castings. The fixture includes a row of aligning pins that extend upwardly from the fixture and the lower ends of each pair of adjacent pins are engaged with the ends of a balancing plate which is fulcrumed within the fixture. The outer projecting ends of the pins are received within the combustion chambers in the cylinder head casting, and the aligning pins and balancing plates tend to level the casting in a longitudinal direction. The lower surface of the casting is adapted to engage three targeting pins, and the lower ends of the targeting pins are engaged with a pivotable balancing plate to thereby level the casting in a transverse direction. Spring loaded locking pins extend upwardly from the fixture and engage the bottom surface of the casting. When the casting is leveled through use of the aligning pins and targeting pins, the locking pins are locked to hold the casting rigidly in place for the grinding operation.
