    He is unlikely to know more than the people who already commented. Proctal... should dig into the schematics he has and he could call up Monarch directly. If its original it will state rapid reverse on the build sheet, Square dial so they should have that if its not in the documentation you already have.

    levers for threading. Now the fun begins. Engage the half
    nuts and when you reach the end of your cut back out the
    tool and raise the lever that reverses the spindle leaving
    the half nuts engaged. The spindle reversing speed can be
    adjusted via the that black knob which also reverses the
    speed of the lead screw. So the saddle can rapid back to
    the starting point. Set the compound screw stop and zero,
    with the little knob on the side and this makes for some
    quick threading without needing to watch the thread dial.
    For long threads still use the dial as usually done.

    This is correct.

    I've only seen one other motor/generator machine that had this feature and that machine had so many other problems that the MG was replaced. Assuming that it works, you may have the only one in captivity.

    The relays in the box with the rheostat operate to switch between the main pair of rheostats and the ones in the box, depending on spindle direction.

    Cal,
    Yesterday I cut a 16 pitch thread on my Monarch EE
    with the ELSR. I did not set the stops for this job as
    it was only one part and thread length was 1-1/2".
    I've owned this lathe for about 20 years and this
    feature has always worked. I do not change the reverse
    speed very often though. I didn't know it was so rare.

    Cal Haines:

    Add this one to your list:

    10EE Lathe No. 15693, DOB 6/1943 Round dial, MG with taper, ELSR and VARIABLE REVERSE SPEED.

    One of three ( 92,93&94 ) sold to Mersenthaler Linotype Co., Brooklyn, NY

    I have spindle attachments from all three numbers. Anyone on PM have Lathe No.'s 15692 or 15694 ??

    I could be wrong, but I'm pretty sure that should be Mergenthaler. They were THE Linotype company of the 20th century, until electronic typesetting took over. As famous for their machines as Monarch is for theirs.

    Not knowing what that dial was for I was concerned it was a fix/work around for an obsolete VS and I was going to loose spindle speed range and/or have to walk around to the back of the machine to change spindle speeds. I hope it still works, but if not, then it seems the only thing I am out is the speed change in reverse when chasing threads. I can live with that. It will be a few more weeks before I get a rotary phase converter and get the lathe under power, but now I am confident the lathe does work as the last two known operators said.
