Slates at start of film explain that we are going to be shown manufacturing processes inside an automobile plant. Glimpse of a 250 acre manufacturing plant of Studebaker Automobiles in South Bend, Indiana. Inside, overhead conveyors are seen moving ladles that are to be filled with molten iron from a cupola furnace. Closeup of molten iron being poured into a ladle. The conveyor moves the full ladle back from the furnace and others move ladles into position and they are filled too. Slate describes casting of engine blocks. Men in foundry are seen guiding a large ladle of molten iron to pour some into a smaller ladle. Then two men using handles to guide the small ladle, proceed to pour molten metal from it into some green sand molds of engine blocks. Closeup of the molten iron being poured into the sand mold. After cooling for some time, a crane lowers a device to remove the cope from the drag of the mold. The solid, but still smoking engine block is then lifted out of the mold with a chain hoist.
Film starts showing a steam driven hammer forging a Studebaker automobile engine part from a flaming hot steel ingot. Two men, in protective clothing and gloves, work together to position a hot steel billet under a steam hammer to forge it into an engine part. Next, a factory worker uses a chain hoist to remove a rough engine crankshaft from a stack. The crankshaft is moved to a machine shop where it is placed in a type of lathe and machined. Closeup of the crankshaft rotating in the machining process. Next, a machinist places the crankshaft between two spindles and spins it by hand to check its balance during rotation. A slate states that the gear cutting machine to be seen next was invented by a woman. Closeup of a gear being cut with cutting tool cooled by fluid. A huge milling machine made by Ingersoll Company of Rockford, Illinois, is shown. Closeup of it milling six engine blocks at the same time. Next, a drilling machine is seen making 36 holes at the same time in an engine part. (Note: The comment about gear cutting machinery and a woman, undoubtedly refers to Catherine “Kate” Anselm Gleason (1865-1933). She worked in the family business which burgeoned as a world wide gear manufacturer when her father, William Gleason invented and patented the first bevel gear planer machine in 1874. During the restrictive culture of her time, she helped shape the global cutting tools industry as a sales engineer for her family’s gear cutting business.)
