I found this thread over at CAS City. Pretty neat:

This Navy style revolver uses a partitioned chamber which is loaded with TWO charges, the front one fired off by a cap which is directed through a side tube into the cylinder, the other charge fired normally. So instead of a six round revolver, you have a 12 round gun.
Apparently, the inventor, and the operator as well took some great risks when using this thing, because you are literally firing off a charge in front of another, and this has been a pet peeve in many "chainfire" discussions.
