This illustration of a diving bell depicts the typical usage and life underwater of a bell diver. The ledge shown on the inside of the bell indicates where the divers sit, the barrel to the right is weighted on the inside to keep it on the bottom and has a leather hose which connects it to the inside of the bell. The two people inside the bell are holding the nozzles connecting to both the barrel of air, and the diver who is working outside of the bell, but still being supplied with air.
