A device that automatically milked cows in place of hand milking was created by Anna Baldwin. The milk was extracted from the cow’s utter into a nearby pail by the equipment, which had a sizable rubber pump attached to the utter.

One of the oldest American patents was issued to Baldwin in 1879, the year the innovation was patented. Unfortunately, her creation was not durable over time. The cow kicked out of discomfort in the breast tissue as a result of the constant suction on her udder. Baldwin’s creation did, however, have an impact on machines that were created decades later.
