I want to know the answer to the following question:
What was Samuel Crompton's invention of 1775?
All the background I'm provided with is that "In 1738, Lewis Paul and John Wyatt, of Birmingham, England, patented the roller spinning machine, as well as the flyer-and-bobbin system for drawing cotton to a more even thickness using two sets of rollers that traveled at different speeds.". Is that enough to answer the question?
