Mason Rotary
 

This is the second machine I got today for my offer of $20. It is also missing its shuttle, bobbin and plate. Its also locked up
Mason Rotary #FR7042912. I can't find its date but from number deductions I figure somewhere between 1915-1921.

I finally got the hand wheel and the face plate off and took a damp rag to the table/base. The machine is not quite as bad as it looks in the initial pictures. Most if not all the decal is there under a lot of grime. The screws in the back plate are stuck so rather than messing them up I'll let them soak over night with a bit of oil. Hopefully it will come off and I can see why its locked up. There was a bit of rust on the presser bar shaft and most of it wiped off with the oil. I am taking pictures as I go so others can see but also so I know how it goes back together should I forget something or end up with a spare part :0

Neat looking machine. Any relationship to White Rotary?

It looks to be a White's machine with a different name, at least according to Treadleon.net. Everything is exactly the same and the Whites Owners Manual shows pretty much the same machine. Even the face plate comes off exactly the same. In my opinion this is a rebadged Whites machine. I'm going to call on Monday to get the exact date.

I have a soft spot for White machines. At age eleven I took my mother's apart and fixed it, thereby gaining rights to sew on it anytime I wanted. By any other name, it is a White. Good of you to rescue it. Looking forward to pictures as you progress.

After a lot of cussing, those stubborn inspection plate screws are finally out. It looks like a dirt dauber had taken up residence at one time as I found its single floor apartment. There is also quite a bit of rust and old grease/oil in the joints. I've heard of some soaking it in a bucket but I'm not sure I'm understanding. Do you mean to just set it in a pan/shallow container and pour the/spray the oil through the parts or actually covering the machine in a bucket of oil?

I contacted Whites @ 1-800-446-2333 and they gave the actual year this machine was manufactured. Its a couple years older than previously thought. The date they gave me was 1913.

Woot Woot Woo Hoo, its alive. I put several drops of Singer oil on each part that even looked like it might move and let it set for a week. Well tonight while I was waiting for the power to go off I put the hand wheel back on, gave it a pull and it moved an inch. I turned the wheel back and it moved another inch. I kept rocking it for about 5 minutes and everything broke free. It still needs more cleaning but its alive and on the road to recovery. Now to find the bobbin case, bobbin and a treadle base.

Crocee,
The hand wheel on a White Rotary goes backwards from Singers. They are awesome machines.

Thanks for reminding me PF. I remember the treadle on website saying something about White's machines being a bit bass ackwards from others. I got the face plate back on after a bit of fiddling and everything moves as it should. Now I can get down to the business of the exterior when the power comes back on. Its not off just yet but it will be. Theres already ice forming on the trees.
