Velocio was inventor of the floating chain, Blake rode with him in 1913 an 
became a convert 
to the floating chain. Velocio abandoned the floating chain in 1919.
Blake wrote an article in the CTC Gazette in 1915 promoting the floating 
chain, in comparison 
to the BSA 3 speed hub. The Brits of the era considered derailleurs a 
French plot to destroy 
good English cycle chains by running them in a less then perfect straight 
line.

Which includes a Cycling article from 1919, showing how to setup a floating 
chain bike,
nicely illustrated.
