by day, Grandpa, i change a lot of dippers these days. I'm a retired maintenance man and loving it, always been a little mechanically inclined and real imaginative, abandoned my first patent about ten years ago,US 6918669 B1 bad timing, middle age crisis and all that. have a lot of time on my hands these days and my imagination is going wild. I'm gonna give this patent thing another try. The present invention that i am working on are wooden shoes with hinges and accordion side walls.
