My Inventor’s Invention

    Benjamin Franklin is most famous for inventing the lighting rod.  Another invention of his is the stove. In the 1700's, lots of people use to build a fire in the fireplace to cook and keep themselves warm, even though it was very dangerous.  In 1742, Benjamin designed a cast-iron stove that would stood by itself.  The cast-iron stove, which was a lot safer than the previous stoves of that time period, did not throw sparks.  This stove allowed people to warm their homes less dangerously and with less wood.  It could heat rooms more efficiently than wall-bound fireplaces.  Unfortunately, he designed it so the smoke would come out from the bottom. Since smoke rises, this made it impossible for his original stove to work properly.   But, even with this major flaw it was better and safer than previous methods.  The stove that he invented allows cooler air to enter through a duct under the floor into the baffle, which directs the flow of the fire's fumes through vents on either side of the stove.  This is what warms the house.  Smoke then exits through a U-shaped duct into the floor.  Benjamin Franklin was offered a patent for his invention.  But he turned it down because "he believed that people's appreciation of his invention was better than any financial reward."

FUN FACT;Franklin never patented his inventions
