- Cradle Scythe, circa 1830 - Nineteenth-century farmers needed to harvest grain quickly before time or weather could destroy it. Harvesters would swing the cradle scythe's blade through ripened fields. The cut grain would fall onto the wooden fingers -- the cradle -- where it would be dumped in neat rows ready for gathering. Skilled cradlers could harvest more grain than those using traditional sickles.

- Lathe, Used by the Wright Brothers, circa 1895 - The Wright brothers' bicycle shop contained several large power tools primarily used for making and repairing bikes. Some were also used to build their early gliders and airplanes. The shop building did not have electricity, so the Putnam lathe, Crescent band saw and Barnes drill press were powered by overhead belts and shafts connected to a single-cylinder gas engine.

- Bicycle Drivetrain, 1890-1910 - The bicycle industry of the late 19th century became a model and resource for automobile builders everywhere. Inventors used bicycle technology -- such as chain drives, wire-spoked wheels, and pneumatic tires -- in many early autos. These drivetrain components came from an Iver Johnson bicycle made between 1890 and 1910.

- Trade Card for Barry's Tricopherous Hair Tonic, 1870-1900 - In the last third of the nineteenth century, an unprecedented variety of consumer goods and services flooded the American market.
