Monarch model A Lathe?

[Metalworker651]

Just aquired this Monarch lathe and it’s missing the ID plate. Swing is about 10” over the bed. And approximately 40” between centers. Any help is greatly appreciated.

Interesting to see what it turns out to be.

By the "K" stamped in the bed, it was a early model K, which I am not familiar with. Model E was the normal 10" lathe of the period, and gearhead 12" lathes were Model K's, so this must be a early cone head K.

The overhead drive system looks to be factory built and is an arrangement I haven't seen before. Monarch made many "one offs" to fulfill customer requirements (normally piecing together different parts of lathes with a special casting here or there). Very interring lathe. More pictures would be helpful.

Thank you for your help. The “K” is the model, is the “359” the serial number? I’ll take some more photos tomorrow. Anything in particular i should photograph?

This lathe was built before 1927 when Monarch started using serial numbers. The abron still has the star knobs so it was made before 1924 when Monarch Patented the cone clutch apron. The number after the K is the lot number. These lot number turned over at least once if not twice. Monarch Lathe still has these lot numbers in their records.

I believe this is the Monarch Junior. They made this lathe for a few years and then sold the design to Sidney Tool Company who made the lathe for several years basically unchanged. I just bought one of these and was able to find better information searching for Monarch Junior Lathe. Once I get the one I bought home I'll clean it up a bit and add a couple photos here.
The Junior came in bed lengths as short at 2.5' and up to 5'. Swings were 9" and 11". There are a few on PM. Here's one

Value and info on Monarc JR lathe

I've had this older Monarch Jr for a few years, got it with a bunch of other items from a shop. Everything works fine and the cross slide and compound seen nice and tight. I believe it's a 9" and it was made in 1921 with about 900 being made. Nice little lathe and be great for a restoration...

The design was sold to or copied by Sheldon Machine and not Sidney Machine. And looking at the photos it does look like a junior. The K stamp through me as i thought model K was different from juniors.

Oops... I've been typing Sidney too many times!!!

The K stamp confused me as well because I was absolutely sure this was an older "Model K". I actually bought the lathe because I thought that was the case and that it should be restored and carefully documented since it represented a rare model. Nope.. just a Monarch Junior. It did come with taper attachment, 3-jaw, 4-jaw and 2 face plates so I guess I'll keep it around.

Included in the purchase was a 10EC which is fairly rare. I'll start a thread on that next year when I get around to restoring it. I'm going to wish I had studied my Electrical Engineering courses a little more throughly once I dive into the motor controllers.
