Happy Women's History Month! This patent model was submitted by a female inventor in 1879. This was her first patented invention, inspired by her work at a Massachusetts paper company. Can you guess what it did? Here are a few clues: • The machine made something still in use today, often when grocery shopping. • The machine could fold paper. • The item it produced was helpfully flat on the bottom.
Have a guess?
