​Spin-O-Matic (patented Nov. 27, 2001 -Patent # US 6,322,072 B1) was based on a suggestion that Jim Winslow's wife, Dory, had made to Jim. She said there should be a way to make a spinner that kids could use without having it hit their fingers on the way around.  He mentioned it to me and I designed a mechanism that would accomplish just that.  It has been used with many different items over the years.
