If I am looking at the picture correctly, and correct me if I am wrong. There are two chains, each coming off of the main drive shaft and going to two different wheels. Also if you look closely, the idler and tensioner are both on the same bracket. From this, I would assume that the bracket is either slightly adjustable or secured. I would assume that is slightly adjustable so that when the chains were cut for each wheel, that the idler on the left could be put into place so that is tensions the one chain run. Then the Spring Loaded tension could tension the other chain run, without having to be moved from its spot, it uses the spring forced to tension it. But that is just what I get out of the picture and the knowledge that I have gained from my engineering classes.

Needless to say, I love it, and have been trying to engineer/manufacture a design for the team that i was a part of to use in their drive systems. Really neat, and would love to see it in action.
