He was awarded the first patent for the flushing toilet (or valve closet) in 1775. This new toilet was an improvement of Sir John Harrington's water closet, which was invented in 1596 and used by Queen Elizabeth I. The water closet was able to flush, but did not have a water trap. Cummings' toilet allowed some water to stay in the bowl after flushing because of the "S trap," a sliding valve between the bowl and trap. This excess water kept the house from smelling like sewage and helped to clean the bowl after use. Many other inventors followed Cummings and contributed their ideas to what is now the modern day toilet.
The toilet lid may not stay up due to a faulty hinge or spring mechanism. It could also be caused by wear and tear over time.

To do that you must jump on the toilet by jumping on the toilet paper. But be careful. If you stay on the toilet paper for more than a few seconds you will fall off. :-)
