1: An Oil Lubricator machine

2: The fold able ironing board

3: The Lawn Sprinkler

A patent is a right granted to an inventor by the federal government that permits the inventor to exclude others from making, selling or using the invention for a period of time. The patent system is designed to encourage inventions that are unique and useful to society.
