Detroit, MI: 1910-1926,1960 Highland Park Assembly Plant and Generating Station

(Satellite, the store and its parking lot is the reuse of the land)

"Gradually, the Rouge Plant surpassed Highland Park in size and importance, and in 1927 the final assembly line moved to the new facility, although Ford tractors and tractor components were made in Highland Park into the 1970s." [miplace]

This day in Michigan history, 1913: Ford Introduces the Assembly Line on December 1, 1913, Henry Ford installs the first moving assembly line for the mass production of an entire automobile. His innovation reduced the time it took to build a car from more than 12 hours to two hours and 30 minutes. Ford’s Model T, introduced in 1908, was simple, sturdy and relatively inexpensive–but not inexpensive enough for Ford, who was determined to build “motor car[s] for the great multitude.” (“When I’m through,” he said, “about everybody will have one.”) In order to lower the price of his cars, Ford figured, he would just have to find a way to build them more efficiently. Ford had been trying to increase his factories’ productivity for years. The workers who built his Model N cars (the Model T’s predecessor) arranged the parts in a row on the floor, put the under-construction auto on skids and dragged it down the line as they worked. Later, the streamlining process grew more sophisticated. Ford broke the Model T’s assembly into 84 discrete steps, for example, and trained each of his workers to do just one. He also hired motion-study expert Frederick Taylor to make those jobs even more efficient. Meanwhile, he built machines that could stamp out parts automatically (and much more quickly than even the fastest human worker could). The most significant piece of Ford’s efficiency crusade was the assembly line. Inspired by the continuous-flow production methods used by flour mills, breweries, canneries and industrial bakeries, along with the disassembly of animal carcasses in Chicago’s meat-packing plants, Ford installed moving lines for bits and pieces of the manufacturing process: For instance, workers built motors and transmissions on rope-and-pulley–powered conveyor belts. In December 1913, he unveiled the pièce de résistance: the moving-chassis assembly line. In February 1914, he added a mechanized belt that chugged along at a speed of six feet per minute. As the pace accelerated, Ford produced more and more cars, and on June 4, 1924, the 10-millionth Model T rolled off the Highland Park assembly line. Though the Model T did not last much longer–by the middle of the 1920s, customers wanted a car that was inexpensive and had all the bells and whistles that the Model T scorned–it had ushered in the era of the automobile for everyone.

This was the second of three plants that Ford built to assemble the Model T, and it began operation on Jan 1, 1910. It was the plant that pioneered the use of an assembly line and a wage of $5 for an 8-hour day.

 This is one of the nine generators that were installed between 1916 and 1919. They were retired by 1926 when electricity was fed from Ford's River Rouge plant.
[The big wheel with some visible copper was a Crocker-Wheeler generator rated at 4474kw DC at 250v. The bigger wheel behind it was the 100-ton, 18' flywheel.[ModelTfordFix] ]

This is a better view of the flywheel and shows one of the engines that drove it. (I don't know if this is the steam side or the gas side.

“This machine, 82 feet long, 46 feet wide, and weighing 750 tons, is one of nine that powered the Ford Motor Company's Highland Park plant while Model Ts were being manufactured there. Together, the nine machines generated 53,000 horsepower. Each had a gas engine and a steam engine mounted on either side of a 4,000-kW DC generator. The gas engines being more efficient than the steam-driven units but less regular in speed, provided economy and power; the steam engines provided regulation and reliability. At the time the units were installed at Highland Park around 1915, they created quite a stir in engineering circles. They were generally regarded as highly innovative and economical means of supplying industrial power."

The generator hall was 400' long.
Here we can clearly see the two engines on either side of the generator and flywheel. Because the steam engine was compound, each unit has three cylinders: high pressure at 36", low pressure at 72" and gas at 42". All of the cylinders had a stroke of 72".
