John Flynn had a sort of what I might call a rolling frame for quilting. It surprised me that he invented something for machine quilting since he was always known for his hand quilting. You might check out his website and see if he still sells them. There is one for sale on eBay for $119.00 called John Flynn Multi frame quilting. I just Google "John Flynn quilting" and it will show a picture of him using this item. Good Luck !!
