  • 254 used a single piece of belt routed continuously through the assembly and then pinned to the final stage at each end of the belt. See attached for a diagram.
  • 233 used two loops of chain, one to drive the first stage and then in a cascading fashion used the first stage to drive the second stage. See my previous post 39 for a diagram.


The devil is definitely in the details with these mechanisms.
This is correct. Thanks for illustrating this for others.
