What an interesting lathe. Anybody ever used something like this?

What is that big arm that is folded up out of the way for?

Looks like a vertical slide. Cut-off tool?

It is a threading device; a thread lead sleeve is held on the back end of the spindle, when the arm carrying the tool is pulled down, the arm on the back end also follows it down where a partial nut on that arm engages the threaded sleeve and causes the slide bar and arms to feed along at the pitch of the desired thread; multiple cuts are taken by feeding in with a slide on the arm that engages the workpiece. Many years ago, Fox lathes used this device for threading operations on their turret lathes.

And THAT'S why I post ads for machines that no one here would want.

Very true. But it seems if John York doesn‘t have an answer the rest of us are stumped.

I once saw a Fox lathe in a junkyard, it was obvious how it worked. They had other weird features, such as a turret that had cross feed and taper capabilities.

Here is a link to a picture of a Fox lathe; note the threading slide, the strange turret and the hand rest for using handheld turning tools; these lathes were used mostly for finishing brass castings for the like of valves and faucets.
