- Bergmann & Company Edison Chemical Meter, circa 1882 - To make money selling electricity, Thomas Edison had to know how much his customers used. This meter used electricity to plate zinc onto electrodes. By weighing the electrodes to see how much zinc had accumulated, Edison's company could calculate how much electricity was being used. This is one of the earliest surviving electrical meters. It was part of Edison's pioneering September 1882 Pearl street system.

- Johnston Harvester Co. Self-Rake Reaper, 1878-1900 - Farmers in the late 1800s saved time and labor by using horse-drawn, self-rake reapers to harvest grain crops. These machines had revolving arms that raked the cut grain off the reaper table and into a neat pile on the ground. Workers trailed behind the reaper, binding the piled grain and stacking the sheaves so they could dry before threshing.
