Cool machine. There was a guy named Shaky Jake Woods who was a fixture on the streets of Ann Arbor from the late 60's until his death in 2007. He was an interesting guy and loved by all. The name of that machine made me think of him. I may need to track one of those down now!
For those from the area, maybe you had one of his bumper stickers on your car "I Brake for Jake".
RIP Jake
