I knew I had a free arm under my printer table in my sewing/computer/guest room. Well, I dragged it out to mend a worn knee and found out it was this model. I tried to thread it but I really don't have a clue. It is all in such a narrow area. Of course I don't have a manual.
I feel like such a bad person, lol, everyone treats their machines so nice and gives them names and all. I have no idea where I got this one, it has just been gathering dust. Like an orphan that showed up on my doorstep.

If any one knows how to thread it I would love to hear from them. BTW, there is a great site I found
www.sewusa.com
that has free threading diagrams for a lot of machines. They sell manuals, and if they have the manual they put the diagram online for free. I thought that was nice of them. Of course they don't have mine.

I am also open to name suggestions. Maybe if I name it I will use it more.

Almost all of the old sewing machines are threaded in a very similar manner. All of the Singer Merritts should thread the same way. Here is a link to the sewusa threading diagram for a different model of the Singer Merritt:

Should work for your machine too.

i have a singer merritt 3314c and its threaded the same as the other merritts, so try and do yours the same way. on that same site.

I just looked at the diagram and my machine, and I do not have the normal tension adjustment. Instead there is a numbered wheel to the left of the thread take-up lever (?). I have never seen a machine before without that tension thingie.
I will try to post a pic tomorrow.

OK here are some pics of the thread area. Sorry they are not real clear. I tried to find a pic of this machine on Google Images, not one. I was getting pictures of herons at Merritt Island NWR, lol.
You can see what I mean about the whole area the thread goes in being about 1/4" wide.

Where is the thread guide on the top of the machine? If it's on the right, I would thread from right to left. If it's on the left, I would try threading from left to right (which I've never seen before on a machine, but I suppose it's possible). It seems to me the tensioning discs must be on the left side where the tension dial is.

on the top back of machine, the thread guide is in the same groove as everything else. I thought about threading it backwards too.

Have you tried threading it to see what happens? I have experimented on some old machines that did not thread normally and (I think) managed to figure all of them out eventually. It's been awhile since I had to do that.....

I think I will try that when I get more time. I like to have a free arm machine. I did not realize it was so obscure.

I have one and can help you with it. This machine is England made, so it threads backwards from the way we do ours. Kind of like the way they drive on the opposite side of the road.
