Brian, a civil engineering student wrote to me looking for additional information on Charles B. Brooks, the inventor of an improved street sweeper and single hole punch. Some people believe that Charles B Brooks invented the "first" street sweeper, however, this is not true.
Brian you touch on a topic that my readers often misunderstand, the difference between inventing the very "first" and inventing an "improvement". Inventions are evolutionary by nature and nearly all patents are issued for "improved" versions of the same invention. For example, Henry Ford invented an "improved" assembly line and not the "first" assembly line like many people believe. However, if people knew how to search for and then read patents they might understand them better. Charles B Brooks was issued patents 556,711, 507,672, 560,154, and 558,719 for his inventions. Brooks writes in his 556,711 patent, "I have invented new and useful improvements to street sweepers" and he goes on to describe in his patent how his street sweeper was better than the street sweepers invented before his.
Hello Mary,
You raise an excellent point. Many people think that they have little chance of actually being the FIRST at thinking up things. They young inventors out here can be just as successful by using the brain power to improve on existing products. So Mary, if you see some kind of machine that you think you can inprove on and have a great idea, what would be your advice to a young inventor?

It is my understanding that Charles B. Brooks did invent the First “self-propelled sweeping truck”. Prior, the sweepers were pulled by horses.
Todd – Charles Brooks signed a sworn statement that he made improvements to that kind of pre-existing street sweeper.
So who invented the first street sweeper?
I really like how you explain who and what happen good job
He may have signed it but under what pretenses? A lot of the early black inventors were not allowed to take credit because of their skin color.
What is the name of the person who invented the first street sweeper?
How many other people improved on the street sweeper prior to Brooks?
It would be quite the job to count everyone, who did so. As these are now historical patents and a trip to a USPTO patent library would be necessary. And that would be just to check this country.
