Benjamin Franklin and his inventions Benjamin Franklin was a very talented man. He invented man yuseful things. We still use some of them nowadays. In the 1740s Franklin invented the Pennsylvania Fireplace. It worked like a normal fireplace but it created more heat than a normal fireplace. People liked the Franklin Stove, as it is also called, but they only used it as a heater and not to cook hot food and drinks. Franklin was also very popular for his bifocals — a wonderful type of glasses. He needed glasses to help him see things far away and close to him. One pair of glasses only helped one of these problems, so Franklin needed to carry two pairs of glasses. One day, he got tired of always changing glasses, so he decided to put two lenses into one pair of glasses. The top lens helped him to see far away, and the bottom lens helped him to see things which' were close to him. He c alled this new type of gl a ss bifocals. Frank l in also invented the ligh t ning rod. This was a mental sick put on houses, barns or other b uildings from fire , heavy sto r ms, light ni n g hit this rod and not the building. This invention saved many buildings from fire. Unfortunately, F ranklin got an electric shock when he was doing this experiment. He did not patent any of the items he invented. A patent is a law which m e ans the inventor protects the use of his or her invention.When you patent your invention,other people cannot produce or use your invention without your agreement .Ben thought his ideas should be used to improve the lives of everyone
