Hendey Lathe Leadscrew Reversing

Hendey leadscrew reversing mechanism, a brief explanation. Since acquiring a Hendey lathe years ago I have been curious about how the leadscrew reversing is accomplished. Having the 12x6 conehead lathe apart gave me a chance to see how the mechanism works. I found the patent information at Keith Rucker's Vintage Machinery site (http://vintagemachinery.org/) - Thanks to Keith for hosting such a valuable resource. Probably not of interest to everyone but hopefully some find it useful. As usual, below is a list of YouTube machinists that I follow and recommend anyone who is interested in machining or the creative process go take a look.
